1. Philosophy / A. Wisdom / 1. Nature of Wisdom
The wisdom of a free man is a meditation on life, not on death [Spinoza]
     Full Idea: A free man thinks of nothing less than of death, and his wisdom is a meditation on life, not on death.
     From: Baruch de Spinoza (The Ethics [1675], IV Pr 67)
     A reaction: Life and death are not so easy to separate. You could hardly be wise about life if you didn't incorporate its finite duration into your wisdom.
If we are not wholly wise, we should live by good rules and maxims [Spinoza]
     Full Idea: The best thing we can do, so long as we lack a perfect knowledge of our feelings, is to conceive a right rule of life, or sure maxims of life - to commit these to memory, and constantly apply these to particular cases.
     From: Baruch de Spinoza (The Ethics [1675], V Pr 10)
     A reaction: This seems to be the role of folk wisdom - to try to plant guidance in the heads of the not-so-wise.
1. Philosophy / D. Nature of Philosophy / 7. Despair over Philosophy
The observation of human blindness and weakness is the result of all philosophy [Hume]
     Full Idea: The observation of human blindness and weakness is the result of all philosophy.
     From: David Hume (Enquiry Conc Human Understanding [1748], IV.I.26)
     A reaction: No wonder some people dislike philosophy. There is no question that the human race is often ludicrously over-confident about its attempts to understand, and a careful examination of the situation tends to undermine such confidence.
1. Philosophy / F. Analytic Philosophy / 4. Conceptual Analysis
If we suspect that a philosophical term is meaningless, we should ask what impression it derives from [Hume]
     Full Idea: When we entertain any suspicion that a philosophical term is without any meaning or idea, we need but enquire "from what impression is that supposed idea derived?"
     From: David Hume (Enquiry Conc Human Understanding [1748], II.17)
1. Philosophy / F. Analytic Philosophy / 5. Linguistic Analysis
We must be careful to keep words distinct from ideas and images [Spinoza]
     Full Idea: It is necessary that we should distinguish between ideas and the words by which things are signified. ...Images, words, and ideas are by many people altogether confounded.
     From: Baruch de Spinoza (The Ethics [1675], II Pr 49)
1. Philosophy / G. Scientific Philosophy / 1. Aims of Science
All experimental conclusions assume that the future will be like the past [Hume]
     Full Idea: All our experimental conclusions proceed upon the supposition that the future will be conformable to the past.
     From: David Hume (Enquiry Conc Human Understanding [1748], IV.II.30)
2. Reason / A. Nature of Reason / 3. Pure Reason
Reason perceives things under a certain form of eternity [Spinoza]
     Full Idea: It is in the nature of reason to perceive things under a certain form of eternity ('sub quadam aeternitatis specie').
     From: Baruch de Spinoza (The Ethics [1675], II Pr 44)
     A reaction: A wonderful, and justly famous, remark. If you don't feel the force (and poetry!) of this, you aren't a philosopher. It is not only appealing, but I don't see how it can fail to be true. Try producing good reasons which only have temporary force.
Reason only explains what is universal, so it is timeless, under a certain form of eternity [Spinoza]
     Full Idea: The foundations of reason are notions which explain those things which are common to all, and these things explain the essence of no individual thing, and must therefore be conceived without any relation to time, but under a certain form of eternity.
     From: Baruch de Spinoza (The Ethics [1675], II Pr 44)
     A reaction: You have to be totally inspired by this even if you totally disagree with it.
2. Reason / A. Nature of Reason / 4. Aims of Reason
Without reason and human help, human life is misery [Spinoza]
     Full Idea: Without mutual help and the cultivation of reason, human beings necessarily live in great misery.
     From: Baruch de Spinoza (Tractatus Theologico-Politicus [1670], 16.05)
     A reaction: A clarion call from a great voice of the Enlightenment. I agree, but in 2017 the rest of western civilization seems to have given up on this ideal. I blame Adorno and Horkheimer.
In so far as men live according to reason, they will agree with one another [Spinoza]
     Full Idea: Men necessarily always agree with one another in so far as they live according to the guidance of reason.
     From: Baruch de Spinoza (The Ethics [1675], IV Pr 35)
     A reaction: I think this was my earliest motivation for getting interested in philosophy. Oddly, the Socratic tradition of philosophy is to challenge and criticise, but the aim is agreement. I sort of believe this idea, despite its wild idealism.
2. Reason / A. Nature of Reason / 7. Status of Reason
Reason is and ought to be the slave of the passions [Hume]
     Full Idea: Reason is and ought to be the slave of the passions, and can never pretend to any other office than to serve and obey them.
     From: David Hume (Treatise of Human Nature [1739], II.III.3)
2. Reason / B. Laws of Thought / 2. Sufficient Reason
There is necessarily for each existent thing a cause why it should exist [Spinoza]
     Full Idea: There is necessarily for each existent thing a cause why it should exist.
     From: Baruch de Spinoza (The Ethics [1675], I Pr 08 n2)
     A reaction: The obvious response is 'how do you know that?' It has to the sort of a priori commitment we expect from a rationalist philosopher. It seems to me quite an appealing candidate for an axiom of human understanding.
2. Reason / D. Definition / 2. Aims of Definition
All the intrinsic properties of a thing should be deducible from its definition [Spinoza]
     Full Idea: The definition of a thing should be such that all the properties of that thing, in so far as it is considered by itself, and not in conjunction with other things, can be deduced from it.
     From: Baruch de Spinoza (Improvement of Understanding [1675], p.35), quoted by E.J. Lowe - What is the Source of Knowledge of Modal Truths? 6
     A reaction: This is exactly what Locke requires of a real essence (though he is pessimistic about ever achieving it). Spinoza is talking of an Aristotelian real definition, which may be complex, and not a lexicographer's short verbal explication.
2. Reason / E. Argument / 3. Analogy
All reasoning concerning matters of fact is based on analogy (with similar results of similar causes) [Hume]
     Full Idea: All our reasonings concerning matters of fact are founded on a species of analogy, which leads us to expect from any cause the same events, which we have observed to result from similar causes.
     From: David Hume (Enquiry Conc Human Understanding [1748], §82)
     A reaction: Interesting. Analogy notoriously becomes problematical when you have only one case (or a few) to go on, as when inferring other minds, or God's existence from natural design.
An analogy begins to break down as soon as the two cases differ [Hume]
     Full Idea: But wherever you depart, in the least, from the similarity of the cases, you diminish proportionably the evidence; and may at last bring it to a very weak analogy.
     From: David Hume (Dialogues Concerning Natural Religion [1751], Part 2)
3. Truth / A. Truth Problems / 1. Truth
Truth is its own standard [Spinoza]
     Full Idea: Truth is its own standard.
     From: Baruch de Spinoza (The Ethics [1675], II Pr 43S)
     A reaction: A gloriously bold solution to all the problems of epistemology. Read the whole of P43S to see the context.
3. Truth / A. Truth Problems / 3. Value of Truth
Spinoza's life shows that love of truth which he proclaims as the highest value [MacIntyre on Spinoza]
     Full Idea: Spinoza's life unites philosophy and practice; he manifests that very impersonal love of truth which he proclaims in his writings as the highest human value.
     From: comment on Baruch de Spinoza (The Ethics [1675]) by Alasdair MacIntyre - A Short History of Ethics Ch.10
     A reaction: Spinoza has become a secular saint in our times. If the big three values are Beauty, Goodness and Truth, why should the third be given top status? I once heard a philosopher say that truth was the only value.
3. Truth / A. Truth Problems / 8. Subjective Truth
For Spinoza, 'adequacy' is the intrinsic mark of truth [Spinoza, by Scruton]
     Full Idea: For Spinoza, the intrinsic mark of truth is the property which he calls 'adequacy'.
     From: report of Baruch de Spinoza (The Ethics [1675]) by Roger Scruton - Short History of Modern Philosophy §5.6
     A reaction: This is presumably the sort of theory to which early rationalists were confined, and it seems to be no advance on Descartes' 'clear and distinct conceptions'. I take it that the coherence theory is a better account of what they were after.
3. Truth / C. Correspondence Truth / 1. Correspondence Truth
A true idea must correspond with its ideate or object [Spinoza]
     Full Idea: A true idea must correspond with its ideate or object.
     From: Baruch de Spinoza (The Ethics [1675], I Ax 6)
     A reaction: Allowing for his usage of 'idea' and 'object', this seems to be a straightforward commitment to the modern correspondence theory, perhaps the earliest clear statement of it. I agree with him.
5. Theory of Logic / B. Logical Consequence / 5. Modus Ponens
If our ideas are adequate, what follows from them is also adequate [Spinoza]
     Full Idea: Whatever ideas follow in the mind from ideas which are adequate in the mind are also adequate.
     From: Baruch de Spinoza (The Ethics [1675], II Pr 40)
     A reaction: This appears to be Modus Ponens, and he calls it (in Sch 1) 'the foundations of our reasoning'. If 'adequate' ideas are knowledge, then this also seems to say that knowledge is closed under known implication.
6. Mathematics / A. Nature of Mathematics / 1. Mathematics
Mathematics deals with the essences and properties of forms [Spinoza]
     Full Idea: Mathematics does not deal with ends, but with the essences and properties of forms (figures), …and has placed before us another rule of truth.
     From: Baruch de Spinoza (The Ethics [1675], IApp)
     A reaction: Just what I need - a nice clear assertion of essentialism in mathematics. Many say maths is all necessary, so essence is irrelevant, but I say explanations occur in mathematics, and that points to essentialism.
6. Mathematics / A. Nature of Mathematics / 2. Geometry
The sum of its angles follows from a triangle's nature [Spinoza]
     Full Idea: It follows from the nature of a triangle that its three angles are equal to two right angles.
     From: Baruch de Spinoza (The Ethics [1675], IV Pr 57)
     A reaction: This is the essentialist view of mathematics, which I take to be connected to explanation, which I take to be connected to the direction of explanation.
The idea of a triangle involves truths about it, so those are part of its essence [Spinoza]
     Full Idea: The idea of the triangle must involve the affirmation that its three angles are equal to two right angles. Therefore this affirmation pertains to the essence of the idea of a triangle.
     From: Baruch de Spinoza (The Ethics [1675], II Pr 49)
     A reaction: This seems to say that the essence is what is inescapable when you think of something. Does that mean that brandy is part of the essence of Napoleon? (Presumably not) Spinoza is ignoring the direction of explanation here.
6. Mathematics / B. Foundations for Mathematics / 5. Definitions of Number / d. Hume's Principle
Two numbers are equal if all of their units correspond to one another [Hume]
     Full Idea: When two numbers are so combin'd, as that the one has always a unit answering to every unit of the other, we pronounce them equal.
     From: David Hume (Treatise of Human Nature [1739], I.III.1)
     A reaction: This became known as Hume's Principle after Frege made use of it for logicism (Foundations §63). It reduces equality to something fairly simple and visual (one-to-one correspondence). But we also say that two logicians or musicians are 'equal' in ability.
6. Mathematics / C. Sources of Mathematics / 4. Mathematical Empiricism / a. Mathematical empiricism
Reason assists experience in discovering laws, and in measuring their application [Hume]
     Full Idea: Abstract reasonings are employed, either to assist experience in the discovery of natural laws, or to determine their influence in particular instances, where it depends upon any precise degree of distance or quantity.
     From: David Hume (Enquiry Conc Human Understanding [1748], IV.I.27)
7. Existence / A. Nature of Existence / 2. Types of Existence
Outside the mind, there are just things and their properties [Spinoza]
     Full Idea: Outside the intellect, there is nothing but substances and their affections.
     From: Baruch de Spinoza (The Ethics [1675], I Pr 04)
     A reaction: This is pretty close to the very sparse ontology espoused by modern philosophers who take their lead from the logic.
The more reality a thing has, the more attributes it has [Spinoza]
     Full Idea: The more reality or being a thing possesses, the more attributes belong to it.
     From: Baruch de Spinoza (The Ethics [1675], I Pr 09)
     A reaction: This commitment to degrees of existence (which I find baffling) is presumably to enable God to be the thing with infinite attributes, and an infinite degree of Being. What percentage of Being would you say you've got (on a good day)?
There is no medium state between existence and non-existence [Hume]
     Full Idea: Betwixt unity and number there can be no medium; no more than betwixt existence and non-existence.
     From: David Hume (Treatise of Human Nature [1739], I.IV.2)
     A reaction: Just to confirm that, as you would expect, the great empiricist has no time for 'subsistence', or shadows and holes having lower grade existece.
7. Existence / A. Nature of Existence / 4. Abstract Existence
We can't think about the abstract idea of triangles, but only of particular triangles [Hume]
     Full Idea: Let any man try to conceive a triangle in general, which is neither Isoceles nor Scalenum, nor has any particular length or proportion of sides; and he will perceive the absurdity of all the scholastic notions with regard to abstraction and general ideas.
     From: David Hume (Enquiry Conc Human Understanding [1748], XII.II.122)
     A reaction: I think there is a basic error in this. I admit that I can only imagine a particular triangle, but it doesn't follow that I am thinking about one triangle. Ontology/epistemology confusion. I picture a shape while believing the shape to be irrelevant.
7. Existence / A. Nature of Existence / 5. Reason for Existence
There must always be a reason or cause why some triangle does or does not exist [Spinoza]
     Full Idea: If a triangle exists, there must be a reason or cause why it exists; and if it does not exist, there must be a reason or cause which hinders its existence or which negates it.
     From: Baruch de Spinoza (The Ethics [1675], I Pr 11)
     A reaction: Hm. Spinoza is setting up a defence of the ontological argument, which seems to require that he lower his normal high standards of argument.
7. Existence / C. Structure of Existence / 1. Grounding / a. Nature of grounding
Men say they prefer order, not realising that we imagine the order [Spinoza]
     Full Idea: Men prefer order to confusion, as if order were something in nature apart from our own imagination.
     From: Baruch de Spinoza (The Ethics [1675], IApp)
7. Existence / D. Theories of Reality / 5. Naturalism
Laws of nature are universal, so everything must be understood through those laws [Spinoza]
     Full Idea: Nature's laws ....are everywhere and always the same; so that there should be one and the same method of understanding the nature of all things whatsoever, namely through nature's universal laws and rules.
     From: Baruch de Spinoza (The Ethics [1675], III Pref)
     A reaction: Leiter calls this Methodological Naturalism, which says that the procedures and findings of philosophy should conform to those of science. I think I'm also a Substantive Naturalist, who says 'that's all there is'.
8. Modes of Existence / B. Properties / 3. Types of Properties
An 'attribute' is what the intellect takes as constituting an essence [Spinoza]
     Full Idea: By 'attribute' I understand that which the intellect perceives of substance, as if constituting its essence.
     From: Baruch de Spinoza (The Ethics [1675], I Def 4)
     A reaction: Note that we would call these 'properties', but Spinoza has a word reserved for the properties of essences. He also has 'modes' of a thing, which are different.
8. Modes of Existence / B. Properties / 8. Properties as Modes
A 'mode' is an aspect of a substance, and conceived through that substance [Spinoza]
     Full Idea: By 'mode' I understand the affections [affectiones] of substance, or that which is in another thing through which also it is conceived.
     From: Baruch de Spinoza (The Ethics [1675], I Def 5)
     A reaction: The attributes actually make up the essential consitution of the thing, and then the modes are entirely dependent on that essence. This is thoroughly Aristotelian, even though 'substantial forms' had been given up by this date.
8. Modes of Existence / C. Powers and Dispositions / 1. Powers
Power is the possibility of action, as discovered by experience [Hume]
     Full Idea: Power consists in the possibility or probability of any action, as discovered by experience and the practice of the world.
     From: David Hume (Treatise of Human Nature [1739], p.313), quoted by George Molnar - Powers 5
     A reaction: [page in OUP edn] This strikes me as blatantly false, and typical of those who confuse epistemology with ontology. It implies that a power that takes everyone by surprise is impossible, by definition.
There may well be powers in things, with which we are quite unacquainted [Hume]
     Full Idea: I am, indeed, ready to allow, that there may be several qualities both in material and immaterial objects, with which we are utterly unacquainted; and if we please to call these powers and efficiency, 'twill be be of little consequence to the world.
     From: David Hume (Treatise of Human Nature [1739], p.168), quoted by George Molnar - Powers 7.2.1
     A reaction: A delightful air of casual indifference. What the classic empiricists needed was a notion of 'best explanation', which would allow them to leap beyond immediate experience. They made plenty of other leaps beyond experience, though Hume hated them.
8. Modes of Existence / C. Powers and Dispositions / 2. Powers as Basic
Things persevere through a force which derives from God [Spinoza]
     Full Idea: The force by which each thing perseveres in its existence follows from the eternal necessity of the nature of God.
     From: Baruch de Spinoza (The Ethics [1675], II Pr 45)
     A reaction: This I take to be an ontology of fundamental powers, but with divine backing, similar to that found in Leibniz. Modern powers theorists leave out God, since it doesn't seem to add anything. [Is this the idea of 'conatus'?] Darwin can't explain the force.
8. Modes of Existence / C. Powers and Dispositions / 4. Powers as Essence
The essence of a thing is its effort to persevere [Spinoza]
     Full Idea: The effort by which each thing endeavours to persevere in its own being is nothing but the actual essence of the thing itself.
     From: Baruch de Spinoza (The Ethics [1675], III Pr 07)
     A reaction: This is exactly the sort of thing that Leibniz frequently said. They were much more conscious of the active power of essences than in the scholastic tradition. This is Nietzsche's will to power. Spinoza talks of 'power' in his demonstration of this.
8. Modes of Existence / C. Powers and Dispositions / 7. Against Powers
We have no idea of powers, because we have no impressions of them [Hume]
     Full Idea: We never have any impression that contains any power or efficacy. We never therefore have any idea of power.
     From: David Hume (Treatise of Human Nature [1739], p.161), quoted by George Molnar - Powers 7.2.1
     A reaction: [page in Selby-Bigges edn] It seems to me plausible that Hume is utterly wrong, because our own mental lives are a direct and constant experience of the physical powers and efficacies of material objects.
The distinction between a power and its exercise is entirely frivolous [Hume]
     Full Idea: The distinction which we sometimes make betwixt a power and the exercise of it is entirely frivolous, and ... neither man nor any other being ought ever to be thought possesst of any ability, unless it be exerted and put into action.
     From: David Hume (Treatise of Human Nature [1739], p.311), quoted by George Molnar - Powers 5
     A reaction: [page in OUP] Molnar says this strong intuition is shared by most of us, but I take the world to be full of people who can play the piano or speak Spanish, but never actually do it. [but see Idea 11942] Most wasps never sting anything.
We cannot form an idea of a 'power', and the word is without meaning [Hume]
     Full Idea: We can have no idea of connexion or power at all, and these words are absolutely without any meaning.
     From: David Hume (Enquiry Conc Human Understanding [1748], 7.2.58)
     A reaction: I would say that this ignores a phenomenon of which Hume is well aware, which is the power of our own minds to generate thoughts and actions. Hume seems to be employing a verificationist theory of meaning
8. Modes of Existence / D. Universals / 6. Platonic Forms / d. Forms critiques
The 'universal' term 'man' is just imagining whatever is the same in a multitude of men [Spinoza]
     Full Idea: Confused notions called 'universal', such as 'man', have arisen because so many images of individual men are formed that they exceed the power of imagination, ...so it imagines that only in which all of them agree, ...expressed by the name 'man'.
     From: Baruch de Spinoza (The Ethics [1675], II Pr 40)
     A reaction: [very compressed] This strikes me as correct. I don't see how you can discuss universals without bringing in the way in which human psychology operates.
8. Modes of Existence / E. Nominalism / 2. Resemblance Nominalism
Momentary impressions are wrongly identified with one another on the basis of resemblance [Hume, by Quine]
     Full Idea: Momentary impressions, according to Hume, are wrongly identified with one another on the basis of resemblance.
     From: report of David Hume (Treatise of Human Nature [1739]) by Willard Quine - Identity, Ostension, and Hypostasis 3
     A reaction: I don't have a Hume quotation for this yet, but Quine is plausibly claiming Hume as a resemblance nominalist, equipped with an error theory about universals.
If we see a resemblance among objects, we apply the same name to them, despite their differences [Hume]
     Full Idea: When we have found a resemblance among several objects, that often occur to us, we apply the same name to all of them, whatever differences we may observe in the degrees of their quantity and quality, and whatever other differences may appear among them.
     From: David Hume (Treatise of Human Nature [1739], I.I.7)
     A reaction: This must to some extent by right, whatever objections can be found. Russell's objection (Idea 4441) wouldn't alter the truth of Hume's observation, thought Hume is attacking universals and Russell defending them.
9. Objects / A. Existence of Objects / 5. Individuation / a. Individuation
Individuation is only seeing that a thing is stable and continuous over time [Hume]
     Full Idea: The principle of individuation is nothing but the invariableness and uninterruptedness of any object through a supposed variation of time, by which the mind can trace it in the different periods of its existence.
     From: David Hume (Treatise of Human Nature [1739], I.IV.2)
     A reaction: Not convinced by this. I can individuate something by an almost instantaneous glimpse. I don't increasingly individuate it as time passes. Instant viewing of type and structure may be enough.
9. Objects / B. Unity of Objects / 1. Unifying an Object / b. Unifying aggregates
A thing is unified if its parts produce a single effect [Spinoza]
     Full Idea: If a number of individuals so unite in one action that they are all simultaneously the cause of one effect, I consider them all, so far, as one individual thing.
     From: Baruch de Spinoza (The Ethics [1675], II Def 7)
     A reaction: Interesting. If a mob burn down a town, is that one effect, making the mob one thing? If a ball breaks a window, is that one effect, or a multitude of knock-on effects? Spinoza's view is very coarse-grained.
9. Objects / B. Unity of Objects / 2. Substance / b. Need for substance
Spinoza implies that thought is impossible without the notion of substance [Spinoza, by Scruton]
     Full Idea: Without the notion of substance, according to Spinoza, thought itself becomes impossible.
     From: report of Baruch de Spinoza (The Ethics [1675]) by Roger Scruton - Short History of Modern Philosophy §5.2
     A reaction: Spinoza's strategy here looks like the right way to approach metaphysics. To what extent is it possible to change our conceptual scheme? Quine seems to imply that there is no limit; Davidson seems to imply that it is impossible.
9. Objects / B. Unity of Objects / 2. Substance / d. Substance defined
Substance is the power of self-actualisation [Spinoza, by Lord]
     Full Idea: For Spinoza a substance is not a 'thing', but the power of actualising its own existence.
     From: report of Baruch de Spinoza (The Ethics [1675], I Pr 08) by Beth Lord - Spinoza's Ethics 1 P11
     A reaction: Does this say anything?
Substance is that of which an independent conception can be formed [Spinoza]
     Full Idea: By substance I mean that which is in itself, and is conceived through itself; in other words, that of which a conception can be formed independently of any other conception.
     From: Baruch de Spinoza (The Ethics [1675], I Def 3)
     A reaction: A striking blurring of epistemology and ontology. He eventually settles for it being a concept rather than a fact of nature. It still begs a thousand questions, but it probably leads to monads and logical atoms.
9. Objects / B. Unity of Objects / 2. Substance / e. Substance critique
The only meaning we have for substance is a collection of qualities [Hume]
     Full Idea: We have no idea of substance, distinct from that of a collection of particular qualities, nor have we any other meaning when we either talk or reason concerning it.
     From: David Hume (Treatise of Human Nature [1739], I.I.6)
     A reaction: This is the standard empiricist view of such things, firmly stated. It is tempting to say that Hume has simply misunderstood the word, since it is precisely intended to mean not the qualities, but what underlies them, and persists.
Aristotelians propose accidents supported by substance, but they don't understand either of them [Hume]
     Full Idea: The peripatetic philosophers carry their fictions still further, and both suppose a substance supporting, which they do not understand, and an accident supported, of which they have as imperfect an idea. The whole system is entirely incomprehensible.
     From: David Hume (Treatise of Human Nature [1739], I.IV.3)
     A reaction: It seems to me that if you put it to Aristotle that he didn't understand 'substantial form', he would concede the point, but nevertheless say that it was ideal at which knowledge aimed. Locke is much more astute than Hume on this.
9. Objects / D. Essence of Objects / 1. Essences of Objects
The essence of a thing is what is required for it to exist or be conceived [Spinoza]
     Full Idea: Many assert that that without which a thing cannot be nor be conceived, belongs to the essence of that thing.
     From: Baruch de Spinoza (The Ethics [1675], II Pr 10)
     A reaction: This is one Aristotelian idea that won't go away, despite the seventeenth century onslaught. It seems obvious that natural kinds, natural objects and human artefacts have properties that can be divided into essential and non-essential.
9. Objects / D. Essence of Objects / 6. Essence as Unifier
Essence gives existence and conception to things, and is inseparable from them [Spinoza]
     Full Idea: To the essence of anything pertains ...that without which the thing can neither be nor be conceived, and which in its turn cannot be nor be conceived without the thing.
     From: Baruch de Spinoza (The Ethics [1675], II Def 2)
     A reaction: Note that essence concerns not only what things are, but also our ability to conceive them.
9. Objects / D. Essence of Objects / 7. Essence and Necessity / b. Essence not necessities
Nothing is essential if it is in every part, and is common to everything [Spinoza]
     Full Idea: That which is common to everything, and which is equally in the part and in the whole, forms the essence of no individual thing.
     From: Baruch de Spinoza (The Ethics [1675], II Pr 37)
     A reaction: I like this, because treating essences as mere necessary properties threatens to include utter trivia and universal generalities, just because they are necessary. Rejecting things as 'trivial' by stipulation won't do.
9. Objects / D. Essence of Objects / 8. Essence as Explanatory
All natures of things produce some effect [Spinoza]
     Full Idea: Nothing exists from whose nature an effect does not follow.
     From: Baruch de Spinoza (The Ethics [1675], I Pr 36)
     A reaction: I take it that this is because it is analytic that essences produce effects, since that is the point of the concept of an essence - as the source of the explanations of the effects.
9. Objects / D. Essence of Objects / 14. Knowledge of Essences
Experience does not teach us any essences of things [Spinoza]
     Full Idea: Experience does not teach us any essences of things.
     From: Baruch de Spinoza (Letters to De Vries [1664], 1664?)
     A reaction: This, along with Leibniz's claim that experience cannot reveal necessities, may constitute a striking criticism of empiricism, but it invites the obvious reply 'so much the worse for essences'. An essence seems to be a theoretical concept, not a priori.
9. Objects / E. Objects over Time / 1. Objects over Time
Changing a part can change the whole, not absolutely, but by its proportion of the whole [Hume]
     Full Idea: Though the change of any considerable part of a mass of matter destroys the identity of the whole, yet we must measure the greatness of the part, not absolutely, but by its proportion to the whole.
     From: David Hume (Treatise of Human Nature [1739], I.IV.6)
     A reaction: This seems to nicely demonstrate that the wholeness is in the mind of the perceiver, and does not simply depend on objective facts. Compare the proportion needed to change my pile of mud and my pile of gold.
A change more obviously destroys an identity if it is quick and observed [Hume]
     Full Idea: A change in any considerable part of a body destroys its identity; but 'tis remarkable that where the change is produced gradually and insensibly we are less apt to ascribe to it the same effect.
     From: David Hume (Treatise of Human Nature [1739], I.IV.6)
     A reaction: Broad spotted that landscapes change too, but so slowly that we barely admit any change at all. The type of change also matters. If my car slowly changes to chocolate the speed of change is a minor factor.
9. Objects / E. Objects over Time / 2. Objects that Change
If identity survives change or interruption, then resemblance, contiguity or causation must unite the parts of it [Hume]
     Full Idea: The objects which are variable or interrupted, and yet are supposed to continue the same, are such only as consist of a succession of parts, connected together by resemblance, contiguity, or causation.
     From: David Hume (Treatise of Human Nature [1739], I.IV.6)
If a republic can retain identity through many changes, so can an individual [Hume]
     Full Idea: As the same individual republic may not only change its members, but also its laws and constitutions; in like manner the same person may vary his character and disposition, as well as his impressions and ideas, without losing his identity.
     From: David Hume (Treatise of Human Nature [1739], I.IV.6)
9. Objects / E. Objects over Time / 7. Intermittent Objects
If a ruined church is rebuilt, its relation to its parish makes it the same church [Hume]
     Full Idea: If a church which was formerly of brick fell to ruin, the parish can build the same church of free-stone, with modern architecture. Neither the form nor materials are the same, but their relation to the parishioners is sufficient to say they are the same.
     From: David Hume (Treatise of Human Nature [1739], I.IV.6)
     A reaction: The clearly invites the question of whether this is type-identity or token-identity. If the parish decided they wanted two churches they obviously wouldn't be the same (even if they then demolished the first one).
9. Objects / E. Objects over Time / 8. Continuity of Rivers
We accept the identity of a river through change, because it is the river's nature [Hume]
     Full Idea: Where the objects are in their nature changeable and inconstant, we admit of a more sudden transition. The nature of a river consists in the motion and change of parts. What is expected appears of less moment than what is unusual and extraordinary.
     From: David Hume (Treatise of Human Nature [1739], I.IV.6)
     A reaction: Aha! Little does Hume realise how Aristotelian he is! Aristotle may have a more objective view of the 'nature' of a thing, but making inferences about identity over time from a thing's essential nature is pure Aristotle.
9. Objects / E. Objects over Time / 9. Ship of Theseus
The purpose of the ship makes it the same one through all variations [Hume]
     Full Idea: The common end [of a ship], in which the parts conspire, is the same under all variations, and affords an easy transition of the imagination from one situation of the body to another.
     From: David Hume (Treatise of Human Nature [1739], I.IV.6)
     A reaction: It is not true that a ship remains the same under ALL variations. Consider gradually changing a yacht into a racing powerboat. You might say the purpose is then changed, but the slight variations in a yacht can slightly change its purpose.
9. Objects / E. Objects over Time / 11. End of an Object
Only an external cause can destroy something [Spinoza]
     Full Idea: A thing cannot be destroyed except by an external cause.
     From: Baruch de Spinoza (The Ethics [1675], III Pr 04)
9. Objects / F. Identity among Objects / 1. Concept of Identity
Both number and unity are incompatible with the relation of identity [Hume]
     Full Idea: Both number and unity are incompatible with the relation of identity.
     From: David Hume (Treatise of Human Nature [1739], I.IV.2)
Multiple objects cannot convey identity, because we see them as different [Hume]
     Full Idea: A mutiplicity of objects can never convey the idea of identity. The mind always pronounces the one not to be the other.
     From: David Hume (Treatise of Human Nature [1739], I.IV.2)
     A reaction: However, if we are talking on the phone about two objects we are viewing, such as two buildings, our descriptions might lead us to conclude that our objects are identical. Thus experience might imply identity.
9. Objects / F. Identity among Objects / 5. Self-Identity
'An object is the same with itself' is meaningless; it expresses unity, not identity [Hume]
     Full Idea: In that proposition 'an object is the same with itself', if the idea expressed by the word 'object' were no way distinguished from that meant by 'itself', we should really mean nothing. ...One single object conveys the idea of unity, not that of identity.
     From: David Hume (Treatise of Human Nature [1739], I.IV.2)
     A reaction: As far as I can see it is mathematicians who like self-identity, to justify x=x, which they need. To say 'this vase is identical with itself' is an empty locution. It expresses either unity or stability over time. See Idea 21292.
Saying an object is the same with itself is only meaningful over a period of time [Hume]
     Full Idea: We cannot, in any propriety of speech, say that an object is the same with itself, unless we mean that the object existent at one time is the same with itself at another time.
     From: David Hume (Treatise of Human Nature [1739], I.IV.2)
     A reaction: This seems correct, but the strict language of identity is superfluous when identifying stolen goods. 'This is my watch', not 'this watch is identical with my watch'.
9. Objects / F. Identity among Objects / 7. Indiscernible Objects
There cannot be two substances with the same attributes [Spinoza]
     Full Idea: In nature there cannot be two or more substances of the same nature or attribute.
     From: Baruch de Spinoza (The Ethics [1675], I Pr 05)
     A reaction: This is the Identity of Indiscernibles.
9. Objects / F. Identity among Objects / 8. Leibniz's Law
Two substances can't be the same if they have different attributes [Spinoza]
     Full Idea: Two substances having different attributes have nothing in common with one another.
     From: Baruch de Spinoza (The Ethics [1675], I Pr 02)
     A reaction: This is the contrapositive of Leibniz's Law (i.e of the Indiscernibility of Identicals). Same things must have same attributes, so if the attributes differ they can't be the same things.
10. Modality / A. Necessity / 10. Impossibility
Things are impossible if they imply contradiction, or their production lacks an external cause [Spinoza]
     Full Idea: A thing is said to be impossible either because the essence of the thing itself or its definition involves a contradiction, or because no external cause exists determinate to the production of such a thing.
     From: Baruch de Spinoza (The Ethics [1675], I Pr 33)
     A reaction: Is the contradiction in nature or in logic? How can he be sure that there doesn't exist some causeless thing?
Nothing we clearly imagine is absolutely impossible [Hume]
     Full Idea: 'Tis an established maxim in metaphysics, that whatever the mind clearly conceives includes the idea of possible existence, or in other words, that nothing we imagine is absolutely impossible.
     From: David Hume (Treatise of Human Nature [1739], I.II.2)
     A reaction: It is important to note that this empiricist approach to what is impossible requires that we 'clearly' conceive the possibility - but how do we evaluate whether we are being clear or not?
10. Modality / A. Necessity / 11. Denial of Necessity
Necessity only exists in the mind, and not in objects [Hume]
     Full Idea: Necessity …is nothing but an internal impression of the mind, or a determination to carry our thoughts from one object to another.
     From: David Hume (Treatise of Human Nature [1739], I.III.16)
     A reaction: The classic statement of the empiricist position. Personally I don't believe it. Non-mental necessities are likely to be natural, or to be features of 'Platonic' objects. A big issue…
10. Modality / B. Possibility / 5. Contingency
We only call things 'contingent' in relation to the imperfection of our knowledge [Spinoza]
     Full Idea: A thing can in no respect be called contingent, save in relation to the imperfection of our knowledge.
     From: Baruch de Spinoza (The Ethics [1675], I Pr 33)
     A reaction: A very good remark. Growing up is largely a realisation of the necessity of human affairs that you thought could be otherwise. (Forgive the pessimism!) As metaphysics, I find this appealing, too.
Contingency is an illusion, resulting from our inadequate understanding [Spinoza, by Cottingham]
     Full Idea: The common notion of 'contingency' is for Spinoza an illusion, which derives from the fact that our view of reality is often inadequate and incomplete.
     From: report of Baruch de Spinoza (The Ethics [1675]) by John Cottingham - The Rationalists p.8
     A reaction: The crux is if there could another universe with different natural laws. Spinoza is in no position to deny the possibility. Cosmologists assume it is possible, and run computer simulations to test it. There is 'metaphysical' and 'natural' necessity.
Reason naturally regards things as necessary, and only imagination considers them contingent [Spinoza]
     Full Idea: It is not in the nature of reason to regard things as contingent, but as necessary; ..hence, it is only through our imagination that we consider things, whether in respect to the future or to the past, as contingent.
     From: Baruch de Spinoza (The Ethics [1675], II Pr 44)
     A reaction: A very interesting claim, which seems to be central to rationalism. The empiricist response must be that imagination (which is founded on experience) is a better guide to metaphysical status than pure reason can ever be.
10. Modality / B. Possibility / 6. Probability
We transfer the frequency of past observations to our future predictions [Hume]
     Full Idea: Where different effects have been found to follow from causes, which are to appearance exactly similar, all these various effects must occur to the mind in the same proportion in transferring the past to the future.
     From: David Hume (Enquiry Conc Human Understanding [1748], VI.47)
10. Modality / B. Possibility / 7. Chance
There is no such thing as chance [Hume]
     Full Idea: There is no such thing as chance in the world.
     From: David Hume (Enquiry Conc Human Understanding [1748], VI.46)
10. Modality / C. Sources of Modality / 1. Sources of Necessity
Divine nature makes all existence and operations necessary, and nothing is contingent [Spinoza]
     Full Idea: All things are conditioned by the necessity of the divine nature, not only to exist, but also to exist and operate in a particular manner, and there is nothing that is contingent.
     From: Baruch de Spinoza (The Ethics [1675], I Pr 29)
     A reaction: This obviously invites the response of the empiricist: how does he know that? Hume says he can't know it, and Leibniz says he knows it a priori. Traditionally, 'necessary' is the dubious term, but maybe it is 'contingent' which is meaningless.
10. Modality / C. Sources of Modality / 6. Necessity from Essence
Necessity is in reference to essence or to cause [Spinoza]
     Full Idea: A thing is called necessary either in reference to its essence or its cause.
     From: Baruch de Spinoza (The Ethics [1675], I Pr 33)
     A reaction: I like any proposal that necessity should be 'in reference to' something, rather than being free-standing. I like to add necessary 'for' something, which is often conceptual necessity. Roots are necessary for trees.
10. Modality / D. Knowledge of Modality / 4. Conceivable as Possible / a. Conceivable as possible
People who are ignorant of true causes imagine anything can change into anything else [Spinoza]
     Full Idea: Those who are ignorant of true causes make complete confusion - thinking that trees might talk just as well as men, that men might be formed from stones as well as seed, and imagine that any form might be changed into any other.
     From: Baruch de Spinoza (The Ethics [1675], I Pr 08 n2)
     A reaction: Spinoza himself can be guilty of this, but it strikes me as a key idea. Humean scepticism about causation seems to me the product of eighteenth century ignorance about the mechanisms of cause and effect which have since been uncovered by science.
Error does not result from imagining, but from lacking the evidence of impossibility [Spinoza]
     Full Idea: The mind does not err from the fact that it imagines, but only insofar as it is considered to lack an idea which excludes the existence of those things which it imagines to be present to it.
     From: Baruch de Spinoza (The Ethics [1675], II Pr 17 s)
     A reaction: These may be the wisest words I have yet found on conceivability and possibility. My example is imagining a bonfire on the moon, which seems possible until you fully grasp what fire is.
10. Modality / E. Possible worlds / 3. Transworld Objects / a. Transworld identity
A horse would be destroyed if it were changed into a man or an insect [Spinoza]
     Full Idea: A horse would as much be destroyed if it were changed into a man as if it were changed into an insect.
     From: Baruch de Spinoza (The Ethics [1675], IV Pref)
     A reaction: He has been referring to essences of things. What if a shire horse is changed into a Shetland pony? If you watched the horse transmute, it would be continuous in a way that two separate creatures are not. Some sort of sameness there.
10. Modality / E. Possible worlds / 3. Transworld Objects / e. Possible Objects
A thing is contingent if nothing in its essence determines whether or not it exists [Spinoza]
     Full Idea: I call individual things contingent in so far as we discover nothing, whilst we attend to their essence alone, which necessarily posits their existence or which necessarily excludes it.
     From: Baruch de Spinoza (The Ethics [1675], IV Def 3)
     A reaction: So something could have an essence which determined that it could not exist, which is presumably a contradiction. That's a very strange sort of essence. Presumably all intrinsically contradictory essences are in some way the same.
11. Knowledge Aims / A. Knowledge / 1. Knowledge
Spinoza's three levels of knowledge are perception/imagination, then principles, then intuitions [Spinoza, by Scruton]
     Full Idea: For Spinoza there are three levels of knowledge: first, sense perception or imagination, second, reasoned reflection leading to principles, and third (the highest), intuition, in which the adequacy of an idea is immediately known.
     From: report of Baruch de Spinoza (The Ethics [1675]) by Roger Scruton - Short History of Modern Philosophy §5.6
     A reaction: This notion of rising levels of knowledge has an obvious background in Plato. The third level is clearly rationalist, where empiricists would probably never aspire to rise above level two. I share the empiricist suspicion of level three.
11. Knowledge Aims / A. Knowledge / 2. Understanding
Understanding is the sole aim of reason, and the only profit for the mind [Spinoza]
     Full Idea: All efforts which we make through reason are nothing but efforts to understand, and the mind, in so far as it uses reason, adjudges nothing as profitable to itself excepting that which conduces to understanding.
     From: Baruch de Spinoza (The Ethics [1675], IV Pr 26)
     A reaction: I wish philosophers would agree that the aim of their subject is to achieve broad and general understanding of reality - and nothing else. If you want to change the world, that isn't philosophy. If you think understanding is impossible, drop philosophy.
11. Knowledge Aims / A. Knowledge / 4. Belief / a. Beliefs
Belief is stronger, clearer and steadier than imagination [Hume]
     Full Idea: Belief is nothing but a more vivid, lively, forcible, firm, steady conception of an object, than what the imagination alone is ever able to attain.
     From: David Hume (Enquiry Conc Human Understanding [1748], V.II.40)
11. Knowledge Aims / A. Knowledge / 4. Belief / b. Elements of beliefs
Belief can't be a concept plus an idea, or we could add the idea to fictions [Hume]
     Full Idea: What is the difference between fiction and belief? It can't be a peculiar idea annexed to a conception which commands our assent, and is wanting to fiction, for then the mind could voluntarily annex this idea to any fiction, and believe what it pleases.
     From: David Hume (Enquiry Conc Human Understanding [1748], V.II.39)
Belief is just a particular feeling attached to ideas of objects [Hume]
     Full Idea: When an object is present to memory or senses, custom carries the imagination to that object which is usually conjoined with it. This carries a feeling different from the loose reveries of fantasy, and in this consists the whole nature of belief.
     From: David Hume (Enquiry Conc Human Understanding [1748], V.II.39)
11. Knowledge Aims / A. Knowledge / 4. Belief / d. Cause of beliefs
Belief is a feeling, independent of the will, which arises from uncontrolled and unknown causes [Hume]
     Full Idea: Belief consists merely in a certain feeling or sentiment; in something, that depends not on the will, but must arise from certain determinate causes and principles, of which we are not master.
     From: David Hume (Treatise of Human Nature, + Appendix [1740], Appen p.2)
     A reaction: This is the opposite of Descartes' 'doxastic voluntarism' (i.e. we choose what to believe). If you want to become a Christian, steep yourself in religious literature, and the company of religious people. It will probably work.
Beliefs are built up by resemblance, contiguity and causation [Hume]
     Full Idea: Belief, where it reaches beyond the memory or senses, arises from resemblance, contiguity or causation, with the same transition of thought and vivacity of conception.
     From: David Hume (Enquiry Conc Human Understanding [1748], V.II.44)
'Natural beliefs' are unavoidable, whatever our judgements [Hume, by Strawson,G]
     Full Idea: Hume has a doctrine of "natural belief", about the sorts of things we can't help believing, in 'common' or everyday life, irrespective of our philosophical conclusions.
     From: report of David Hume (Enquiry Conc Human Understanding [1748]) by Galen Strawson - The Secret Connexion App C
11. Knowledge Aims / A. Knowledge / 4. Belief / e. Belief holism
Unlike Descartes' atomism, Spinoza held a holistic view of belief [Spinoza, by Schmid]
     Full Idea: Unlike Descartes, who held an atomist theory of belief (that we can assent to a belief quite independently of our other beliefs), Spinoza endorsed a holistic theory of belief - that our degree of affirmation is essentially determined by our other ideas.
     From: report of Baruch de Spinoza (The Ethics [1675], II Pr 49S) by Stephan Schmid - Faculties in Early Modern Philosophy 3
     A reaction: Since I am a fan of the coherence theory of justification, I seem obligated to accept a fairly holistic account of the acceptance of beliefs. Descartes is a foundationalist.
11. Knowledge Aims / B. Certain Knowledge / 1. Certainty
You only know you are certain of something when you actually are certain of it [Spinoza]
     Full Idea: Who can know that he understands some thing unless he first understands it? That is, who can know that he is certain about some thing unless he is first certain about it?
     From: Baruch de Spinoza (The Ethics [1675], II Pr 43S)
     A reaction: This seems to beg the question, which concerns how you get to the state of full understanding or certainty in the first place. Spinoza thinks only certainty counts as knowledge, which seems to derive from Descartes. I prefer Peirce.
A man who assents without doubt to a falsehood is not certain, but lacks a cause to make him waver [Spinoza]
     Full Idea: When we say that a man assents to what is false and does not doubt it, we do not say that he is certain, but merely that he does not doubt, that is, that he assents to what is false, because there are no causes sufficient to make his imagination waver.
     From: Baruch de Spinoza (The Ethics [1675], II Pr 49)
     A reaction: This is a seventeenth century rationalist desperate to say that the reason can deliver certainty, in the face of idiots who are totally certain about astrology, fairies and what not. Vain hope, I'm afraid. Fallibilist rationalism is required.
True ideas intrinsically involve the highest degree of certainty [Spinoza]
     Full Idea: No one who has a true idea is ignorant that a true idea involves the highest certitude; to have a true idea signifying just this, to know a thing perfectly or as well as possible.
     From: Baruch de Spinoza (The Ethics [1675], II Pr 43)
     A reaction: This wildly optimistic view is found in rationalists of the period. Rationalism only becomes tolerable if fallibilism is added to it. See Bonjour.
11. Knowledge Aims / B. Certain Knowledge / 5. Cogito Critique
'I think' is useless, because it is contingent, and limited to the first person [Spinoza, by Scruton]
     Full Idea: The proposition 'I think' was useless to Spinoza, because it expresses a merely contingent proposition, where certainty must be founded in necessity, and because it refers to the first person, when truth comes from rising above our own mentality.
     From: report of Baruch de Spinoza (The Ethics [1675]) by Roger Scruton - Short History of Modern Philosophy Ch.5
     A reaction: I find both of these criticisms very appealing. One might simply say that the starting point of philosophy is not the process of thinking, but the contents of thinking. Descartes' move is like astronomers becoming obsessed with telescopes.
11. Knowledge Aims / C. Knowing Reality / 1. Perceptual Realism / c. Representative realism
Hume says objects are not a construction, but an imaginative leap [Hume, by Robinson,H]
     Full Idea: Hume's idea is that we move from private impressions to the physical world, not by an unconscious analytical construction but by a spontaneous imaginative leap.
     From: report of David Hume (Treatise of Human Nature [1739]) by Howard Robinson - Perception IX.6
     A reaction: The idea that objects are 'constructions' seems to have originated with Russell. Hume seems closer to the actual process, which is virtually instantaneous. They both forget that you can follow up the construction or leap with a cool evaluation.
12. Knowledge Sources / A. A Priori Knowledge / 9. A Priori from Concepts
Relations of ideas are known by thought, independently from the world [Hume]
     Full Idea: Relations of Ideas are discoverable by the mere operation of thought, without dependence on what is anywhere existent in the universe.
     From: David Hume (Enquiry Conc Human Understanding [1748], IV.I.20)
12. Knowledge Sources / B. Perception / 2. Qualities in Perception / e. Primary/secondary critique
If secondary qualities (e.g. hardness) are in the mind, so are primary qualities like extension [Hume]
     Full Idea: It is agreed that all sensible qualities of objects, such as hard or hot, are secondary, and exist in the mind and not in objects; but then this also follows for the primary qualities of extension and solidity.
     From: David Hume (Enquiry Conc Human Understanding [1748], XII.I.122)
     A reaction: he mentions Berkeley
12. Knowledge Sources / B. Perception / 3. Representation
It never occurs to people that they only experience representations, not the real objects [Hume]
     Full Idea: Men instinctively suppose the very images presented by the senses to be the external objects, and never entertain any suspicion that the one is nothing but representations of the other.
     From: David Hume (Enquiry Conc Human Understanding [1748], XII.I.117)
12. Knowledge Sources / B. Perception / 5. Interpretation
If the body is affected by an external object, the mind can't help believing that the object exists [Spinoza]
     Full Idea: If the human body is affected in a manner which involves the nature of any external body, the human mind will regard the said external body as actually existing.
     From: Baruch de Spinoza (The Ethics [1675], II Pr 17)
     A reaction: This is like one of Hume's 'natural beliefs', and seems to me a powerful idea. One of the basic questions of epistemology is, apart from the question 'which beliefs can I justify?', also 'which beliefs can I never abandon?' Skip the scepticism?
12. Knowledge Sources / C. Rationalism / 1. Rationalism
The eyes of the mind are proofs [Spinoza]
     Full Idea: The eyes of the mind … are none other than proofs.
     From: Baruch de Spinoza (The Ethics [1675], V Pr 23)
     A reaction: A wonderful slogan for rationalists! Technically it sounds a bit dodgy, as steps seem to be required for a proof, whereas the eyes of the mind presumably offer a priori intuitions, or clear and distinct conceptions. In essence, he is right.
12. Knowledge Sources / D. Empiricism / 1. Empiricism
A proposition cannot be intelligible or consistent, if the perceptions are not so [Hume]
     Full Idea: No proposition can be intelligible or consistent with regard to objects, which is not so with regard to perceptions.
     From: David Hume (Treatise of Human Nature, + Appendix [1740], Appendix)
     A reaction: An interesting variant on expressions of the empiricist principle. Presumably one can say intelligible things about Escher drawings.
Hume is loose when he says perceptions of different strength are different species [Reid on Hume]
     Full Idea: When Hume divides all perceptions into two classes or species, distinguished by their degrees of force and vivacity, this is loose and unphilosophical. To differ in species is one thing, to differ in degree is another.
     From: comment on David Hume (Enquiry Conc Human Understanding [1748], II.12) by Thomas Reid - Essays on Intellectual Powers 1: Preliminary 1
     A reaction: This is Hume's 'impressions' and 'ideas'. As usual with Reid, this is a very astute criticism. Reid is a direct realist, so his solution is to view ideas as weakened impressions. If impressions are strong ideas, you get idealism (which is bad!).
All reasoning about facts is causal; nothing else goes beyond memory and senses [Hume]
     Full Idea: All reasonings concerning matters of fact seem to be founded on the relation of cause and effect. By means of that relation alone we can go beyond of our memory and senses.
     From: David Hume (Enquiry Conc Human Understanding [1748], IV.I.22)
All objects of enquiry are Relations of Ideas, or Matters of Fact [Hume]
     Full Idea: All objects of human reason or enquiry may naturally be divided into two kinds, to wit, Relations of Ideas, and Matters of Fact.
     From: David Hume (Enquiry Conc Human Understanding [1748], IV.I.20)
Impressions are our livelier perceptions, Ideas the less lively ones [Hume]
     Full Idea: 'Impressions' are our more lively perceptions, when we hear, see, feel, love, hate, desire or will. 'Ideas' are less lively perceptions, when we reflect on any of those sensations or movements.
     From: David Hume (Enquiry Conc Human Understanding [1748], II.12)
If books don't relate ideas or explain facts, commit them to the flames [Hume]
     Full Idea: If we take in hand any volume of divinity or metaphysics, ask 'Does it contain any abstract reasoning concerning quantity or number?' No. 'Or experimental reason on matters of fact and existence?' No. Commit it then to the flames.
     From: David Hume (Enquiry Conc Human Understanding [1748], XII.III.132)
All ideas are copies of impressions [Hume]
     Full Idea: All our ideas or more feeble perceptions are copies of our impressions or more lively ones.
     From: David Hume (Enquiry Conc Human Understanding [1748], II.13)
12. Knowledge Sources / D. Empiricism / 2. Associationism
Once we have experienced two feelings together, one will always give rise to the other [Spinoza]
     Full Idea: If the mind has once been affected by two affects at once, then afterwards, when it is affected by one of them, it will also be affected by the other.
     From: Baruch de Spinoza (The Ethics [1675], III Pr14)
     A reaction: This strikes me as better expressed than Hume's version, which relies on examples. It is more generalised than Hume, since it will cover contiguity and resemblance and causation, all under the heading of the arising affects.
All ideas are connected by Resemblance, Contiguity in time or place, and Cause and Effect [Hume]
     Full Idea: To me, there appear to be only three principles of connection between ideas, namely, Resemblance, Contiguity in time or place, and Cause or Effect.
     From: David Hume (Enquiry Conc Human Understanding [1748], III.19)
Associationism results from having to explain intentionality just with sense-data [Robinson,H on Hume]
     Full Idea: The limited theories of Berkeley and Hume have to be reductive, because they have to explain intentionality in terms of some kind of relation between sense-data; this predicament gives rise to the associationist accounts of psychology and meaning.
     From: comment on David Hume (Treatise of Human Nature [1739]) by Howard Robinson - Perception 1.4
     A reaction: An illuminating explanation. Robinson seems to be implying that we should accept something like Searle's 'intrinsic' intentionality as basic, rather than intentionality built up from smaller components as Hume and Dennett suggest.
12. Knowledge Sources / D. Empiricism / 4. Pro-Empiricism
How could Adam predict he would drown in water or burn in fire? [Hume]
     Full Idea: Adam, though his rational faculties be supposed, at the very first, entirely perfect, could not have inferred from the fluidity and transparency of water, that it would suffocate him, or from the light and warmth of fire that it would consume him.
     From: David Hume (Enquiry Conc Human Understanding [1748], IV.I.23)
We can only invent a golden mountain by combining experiences [Hume]
     Full Idea: The creative power of the mind amounts to no more than the faculty of compounding, transposing, augmenting or diminishing the materials afforded us by the sense or experience. For example, a golden mountain or a virtuous horse come from joining ideas.
     From: David Hume (Enquiry Conc Human Understanding [1748], II.13)
     A reaction: The example of the Golden Mountain comes from Aguinas Quodlibeta 8.2.1. The original idea is in Sextus Empiricus.
Events are baffling before experience, and obvious after experience [Hume]
     Full Idea: Every event, before experience, is equally difficult and incomprehensible; and every event, after experience, is equally easy and intelligible.
     From: David Hume (Dialogues Concerning Natural Religion [1751], Part 8)
     A reaction: If you don't believe this, spend some time watching documentaries about life in the deep oceans. Things beyond imagination swim around in front of you. But we can extrapolate, once the possibilities are revealed by experience.
We cannot form the idea of something we haven't experienced [Hume]
     Full Idea: A blind man can form no notion of colours; a deaf man of sounds. ….A Laplander or Negro has no notion of the relish of wine. ….A man of mild manners can form no idea of inveterate revenge or cruelty.
     From: David Hume (Enquiry Conc Human Understanding [1748], II.15)
You couldn't reason at all if you lacked experience [Hume]
     Full Idea: An unexperienced reasoner could be no reasoner at all, were he absolutely unexperienced.
     From: David Hume (Enquiry Conc Human Understanding [1748], V.I.36 n.1)
When definitions are pushed to the limit, only experience can make them precise [Hume]
     Full Idea: When we have pushed up definitions to the most simple ideas and still find some ambiguity and obscurity, how can we render them altogether precise and determinate? Produce the impressions or original sentiments from which the ideas were copied.
     From: David Hume (Enquiry Conc Human Understanding [1748], VII.I.49)
Only madmen dispute the authority of experience [Hume]
     Full Idea: None but a fool or a madman will ever pretend to dispute the authority of experience.
     From: David Hume (Enquiry Conc Human Understanding [1748], IV.II.31)
12. Knowledge Sources / D. Empiricism / 5. Empiricism Critique
Hume mistakenly lumps sensations and perceptions together as 'impressions' [Scruton on Hume]
     Full Idea: The greatest weakness in Hume's philosophy is his use of the term 'impression' to refer to both sensations and perceptions.
     From: comment on David Hume (Enquiry Conc Human Understanding [1748]) by Roger Scruton - Modern Philosophy:introduction and survey 24
Even Hume didn't include mathematics in his empiricism [Hume, by Kant]
     Full Idea: Even Hume did not make empiricism so universal as to include mathematics in it.
     From: report of David Hume (Treatise of Human Nature [1739]) by Immanuel Kant - Critique of Practical Reason Pref
     A reaction: Hume didn't actually exclude mathematics, and the notion of 'relations of ideas' is a pointer. Subsequent empiricist have offered promising accounts. Personally I like the idea that patterns are the key idea.
If a person had a gap in their experience of blue shades, they could imaginatively fill it in [Hume]
     Full Idea: Suppose a person to be perfectly acquainted with all colours, except one particular shade of blue. It must be possible for him to raise up from his own imagination the idea of that particular shade, though never conveyed to him by the senses.
     From: David Hume (Enquiry Conc Human Understanding [1748], II.16)
     A reaction: [compressed] He dismisses this as 'so singular it is scarcely worth observing', but it is crucial. It isn't 'singular'. We do it all the time, by extrapolating from experiences and interpolating between them. Thus we extend knowledge beyond experience.
13. Knowledge Criteria / A. Justification Problems / 3. Internal or External / a. Pro-internalism
Anyone who knows, must know that they know, and even know that they know that they know.. [Spinoza]
     Full Idea: If a man knows anything, he, by that very fact, knows that he knows it, and at the same time knows that he knows that he knows it, and so on to infinity.
     From: Baruch de Spinoza (The Ethics [1675], II Pr 21)
     A reaction: A delightfully bold claim! This is 'super internalism', but it seems to require that we must be certain in order to know, whereas I think my own view is internalist but 'fallibilist' - I know, while admitting I could be wrong.
13. Knowledge Criteria / B. Internal Justification / 4. Foundationalism / c. Empirical foundations
Reasons for belief must eventually terminate in experience, or they are without foundation [Hume]
     Full Idea: If I ask why you believe some fact, you must tell me a reason, which will be some other fact, connected with it. But this process must terminate in a fact which is present to your memory or senses; or you must allow that the belief is without foundation.
     From: David Hume (Enquiry Conc Human Understanding [1748], V.I.37)
     A reaction: A classic quotation of empirical foundationalism. The rival view would be that the process does not terminate at all, but nevertheless builds up a persuasive picture which is foundational.
13. Knowledge Criteria / B. Internal Justification / 4. Foundationalism / f. Foundationalism critique
There is no certain supreme principle, or infallible rule of inference [Hume]
     Full Idea: There is no original supreme principle that is self-evident and convincing; nor, if there were, could we advance a step beyond it, but by those very faculties of which sceptics are supposed to be already diffident.
     From: David Hume (Enquiry Conc Human Understanding [1748], XII.I.116)
     A reaction: This I take to be the chief exponent of empirical foundationalism attacking rational foundationalism. The problem of 'advancing beyond' basic beliefs is also a problem for Hume's position.
13. Knowledge Criteria / B. Internal Justification / 5. Coherentism / b. Pro-coherentism
Encounters with things confuse the mind, and internal comparisons bring clarity [Spinoza]
     Full Idea: The mind has only a confused knowledge of itself, its own body, and external bodies, as long as it is perceived from fortuitous encounters with things, ...and not internally, from the agreements, differences and oppositions of a number of things at once.
     From: Baruch de Spinoza (The Ethics [1675], II Pr 29s)
     A reaction: [compressed] This is a very nice expression of the commitment to coherence as justification, typical of the rationalist view of things. Empiricists are trapped in an excessively atomistic concept of knowledge (one impression or sense datum at a time).
13. Knowledge Criteria / C. External Justification / 7. Testimony
We think testimony matches reality because of experience, not some a priori connection [Hume]
     Full Idea: The reason why we place any credit in witnesses and historians, is not derived from any connexion, which we perceive a priori, between testimony and reality, but because we are accustomed to find a conformity between them.
     From: David Hume (Enquiry Conc Human Understanding [1748], X.i.89)
     A reaction: Well he would say that, wouldn't he? If there is no connection in testimony, presumably there can be no a priori connection with private experience, but there is a danger of never getting started, and ending in anti-realism.
Good testimony needs education, integrity, motive and agreement [Hume, by PG]
     Full Idea: Reliable testimony needs a good number of educated people, all of undoubted integrity, who have a lot to lose if they are caught lying, reporting very public events.
     From: report of David Hume (Enquiry Conc Human Understanding [1748], X.II.92) by PG - Db (ideas)
     A reaction: A nice checklist for flying saucer sightings etc: education, integrity, lying risky, very public. If any of those fail, it comes down to likelihood (apply Bayes?) and character assessment.
13. Knowledge Criteria / C. External Justification / 8. Social Justification
Mathematicians only accept their own proofs when everyone confims them [Hume]
     Full Idea: There is no Mathematician so expert as to place entire confidence in any truth upon his discovery of it. ..Every time he runs over his proofs his confidence encreases, ..and is rais'd to perfection by the applause of the learned world.
     From: David Hume (Treatise of Human Nature [1739], IV.1.4)
     A reaction: [compressed] Quoted by Kitcher, and a nice example of the social nature of 'warrants', even in mathematics. It was illustrated well in the 1990s by the story of the proof of Fermat's Last Theorem by Andrew Wiles.
13. Knowledge Criteria / D. Scepticism / 1. Scepticism
Reason can never show that experiences are connected to external objects [Hume]
     Full Idea: Reason can never find any convincing argument from experience to prove that perceptions are connected with any external objects.
     From: David Hume (Enquiry Conc Human Understanding [1748], XII.I.121)
Mitigated scepticism draws attention to the limitations of human reason, and encourages modesty [Hume]
     Full Idea: A mitigated scepticism … can make dogmatical reasoners become sensible of the strange infirmities of human understanding, and inspire them with more modesty and reserve.
     From: David Hume (Enquiry Conc Human Understanding [1748], XII.III.129)
Anaxarchus said that he was not even sure that he knew nothing [Anaxarchus, by Diog. Laertius]
     Full Idea: Anaxarchus said that he was not even sure that he knew nothing.
     From: report of Anaxarchus (fragments/reports [c.340 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 09.10.1
13. Knowledge Criteria / D. Scepticism / 2. Types of Scepticism
Hume became a total sceptic, because he believed that reason was a deception [Hume, by Kant]
     Full Idea: David Hume gave way entirely to scepticism, since he believed himself to have discovered in what is generally held to be reason a deception of our faculty of cognition.
     From: report of David Hume (Treatise of Human Nature [1739]) by Immanuel Kant - Critique of Pure Reason B128
     A reaction: Unfair to Hume, who was very opposed to global scepticism (see Ideas 2240 and 2241), and voted only for 'mitigated scepticism' (see Idea 2242). On the other hand, there is no greater opposition in philosophy than Kant and Hume on 'pure reason'.
Mitigated scepticism sensibly confines our enquiries to the narrow capacity of human understanding [Hume]
     Full Idea: Mitigated scepticism is an advantage to mankind, as it limits our enquiries to such subjects as are best adapted to the narrow capacity of human understanding.
     From: David Hume (Enquiry Conc Human Understanding [1748], XII.III.130)
13. Knowledge Criteria / D. Scepticism / 3. Illusion Scepticism
Examples of illusion only show that sense experience needs correction by reason [Hume]
     Full Idea: Trite sceptical examples, such as the oar bent in water, or double images when the eye is pressed, are only sufficient to prove that senses alone are not dependable, but we must correct their evidence with reason.
     From: David Hume (Enquiry Conc Human Understanding [1748], XII.I.117)
13. Knowledge Criteria / D. Scepticism / 6. Scepticism Critique
The main objection to scepticism is that no good can come of it [Hume]
     Full Idea: The chief and most confounding objection to excessive scepticism is that no durable good can ever result from it.
     From: David Hume (Enquiry Conc Human Understanding [1748], XII.II.128)
It is a very extravagant aim of the sceptics to destroy reason and argument by means of reason and argument [Hume]
     Full Idea: It may seem a very extravagant attempt of the sceptics to destroy reason by argument and ratiocination; yet is this the grand scope of all their enquiries and disputes.
     From: David Hume (Enquiry Conc Human Understanding [1748], XII.II.124)
14. Science / C. Induction / 1. Induction
The idea of inductive evidence, around 1660, made Hume's problem possible [Hume, by Hacking]
     Full Idea: Hume's sceptical problem of induction could not have arisen much before 1660, for there was no concept of inductive evidence in terms of which to raise it.
     From: report of David Hume (Treatise of Human Nature [1739]) by Ian Hacking - The Emergence of Probability Cont 19
     A reaction: Hacking is the expert, but Ideas 1683 and 1886 suggest there was some thinking on the problem in the ancient world. The worry about whether the future would be like the past must occasionally have bothered someone.
14. Science / C. Induction / 2. Aims of Induction
We assume similar secret powers behind similar experiences, such as the nourishment of bread [Hume]
     Full Idea: We always presume, when we see like sensible qualities, that they have like secret powers, and expect that effects, similar to those which we have experienced, will follow from them. …Thus, we expect bread to nourish us, from previous experience.
     From: David Hume (Enquiry Conc Human Understanding [1748], IV.II.29)
14. Science / C. Induction / 3. Limits of Induction
Reason cannot show why reliable past experience should extend to future times and remote places [Hume]
     Full Idea: The main question on which I would insist is why reliable past experience should be extended to future times, and to other objects, which for ought we know, may be only in appearance similar. …No reasoning can show this.
     From: David Hume (Enquiry Conc Human Understanding [1748], IV.II.30)
Induction can't prove that the future will be like the past, since induction assumes this [Hume]
     Full Idea: It is impossible that any arguments from experience can prove the resemblance of the past to the future, since all these arguments are founded on the supposition of this resemblance.
     From: David Hume (Enquiry Conc Human Understanding [1748], IV.II.32)
All inferences from experience are effects of custom, not reasoning [Hume]
     Full Idea: All inferences from experience are effects of custom, not reasoning.
     From: David Hume (Enquiry Conc Human Understanding [1748], V.I.36)
Fools, children and animals all learn from experience [Hume]
     Full Idea: It is certain that the most ignorant and stupid peasants - nay infants, nay even brute beasts - improve by experience.
     From: David Hume (Enquiry Conc Human Understanding [1748], IV.II.33)
If we infer causes from repetition, this explains why we infer from a thousand objects what we couldn't infer from one [Hume]
     Full Idea: If after the constant conjunction of two objects (e.g. heat and flame) we are determined by custom alone to expect the one from the appearance of the other,this explains why we can draw an inference from a thousand objects which we couldn't draw from one.
     From: David Hume (Enquiry Conc Human Understanding [1748], V.I.36)
     A reaction: This is Hume's best statement of the problem of the difficulty of demonstration the logic of induction.
14. Science / C. Induction / 4. Reason in Induction
Premises can support an argument without entailing it [Pollock/Cruz on Hume]
     Full Idea: Contrary to what Hume supposed, it must be possible for the premises of an argument to support a conclusion without logically entailing it.
     From: comment on David Hume (Enquiry Conc Human Understanding [1748]) by J Pollock / J Cruz - Contemporary theories of Knowledge (2nd) §1.2
     A reaction: This seems to me an extremely important point, made with nice clarity. It is why people who are good at logic are not necessarily good at philosophy. The latter is about thinking rationally, not following the laws of deduction.
Hume just shows induction isn't deduction [Williams,M on Hume]
     Full Idea: All that Hume has really shown with his argument is that induction is not deduction.
     From: comment on David Hume (Enquiry Conc Human Understanding [1748], IV.II.29) by Michael Williams - Problems of Knowledge Ch.18
14. Science / D. Explanation / 2. Types of Explanation / f. Necessity in explanations
To understand a phenomenon, we must understand why it is necessary, not merely contingent [Spinoza, by Cottingham]
     Full Idea: Adequate understanding of a phenomenon, for Spinoza, involves a complete understanding of its causes, and this in turn involves a dissolving of the illusion of contingency and a recognition of the necessity of its being thus and not otherwise.
     From: report of Baruch de Spinoza (The Ethics [1675]) by John Cottingham - The Rationalists p.168
     A reaction: This is the appeal of the rationalist dream. We want a god-like grasp of things, not a superficial perception of what seems to be going on.
14. Science / D. Explanation / 2. Types of Explanation / k. Explanations by essence
To understand the properties we must know the essence, as with a circle [Spinoza]
     Full Idea: If a circle is defined as a figure in which lines from centre to circumference are equal, such definitions do not explain the essence of a circle, but only a property. The properties of a thing are not understood as long as their essences are not known.
     From: Baruch de Spinoza (Improvement of Understanding [1675], §95), quoted by Cover,J/O'Leary-Hawthorne,J - Substance and Individuation in Leibniz 1.2.1
     A reaction: This is the traditional Aristotelian view of essence, and the example of a circle is nice, though I am not sure what the essence of a circle might be. Presumably ALL the properties of a circle must flow from it.
15. Nature of Minds / A. Nature of Mind / 1. Mind / a. Mind
The human mind is the very idea or knowledge of the human body [Spinoza]
     Full Idea: The human mind is the very idea or knowledge of the human body.
     From: Baruch de Spinoza (The Ethics [1675], II Pr 19)
     A reaction: This is close to Aristotle's claim that the 'psuché' is the 'form' of the body. Spinoza is appealingly modern in his view. The mapping of the body (our prioprioceptic sense) strikes me as central to the nature of the mind.
15. Nature of Minds / A. Nature of Mind / 1. Mind / b. Purpose of mind
Knowledge is the essence of the mind [Spinoza]
     Full Idea: The essence of our mind consists solely in knowledge.
     From: Baruch de Spinoza (The Ethics [1675], V Pr 36 n)
     A reaction: This is in a context of discussing the human relation to God. See Keith Hossack's 'The Metaphysics of Knowledge' for an exploration of this idea. (@BenedictSpinoza came up with this one)
15. Nature of Minds / A. Nature of Mind / 1. Mind / c. Features of mind
The will is not a desire, but the faculty of affirming what is true or false [Spinoza]
     Full Idea: By the will I understand a faculty of affirming or denying, but not a desire; a faculty, I say, by which the mind affirms or denies that which is true or false.
     From: Baruch de Spinoza (The Ethics [1675], II Pr 48)
     A reaction: This is to be compared with the empiricist tendency to say that there are nothing but desires. On the whole I'm with Spinoza here. Hobbes thinKs of actions in the world, but Spinoza sees the will as operating in the process of reasoning.
Will and intellect are the same thing [Spinoza]
     Full Idea: The will and the intellect are one and the same.
     From: Baruch de Spinoza (The Ethics [1675], II Pr 49)
The will is finite, but the intellect is infinite [Spinoza]
     Full Idea: The will is distinguished from the intellect, the latter being finite, the former infinite.
     From: Baruch de Spinoza (The Ethics [1675], II Pr 49)
15. Nature of Minds / A. Nature of Mind / 5. Unity of Mind
Spinoza held that the mind is just a bundle of ideas [Spinoza, by Schmid]
     Full Idea: Spinoza held a bundle theory of the mind, according to which our mind is but a bundle 'composed of a great many ideas'.
     From: report of Baruch de Spinoza (The Ethics [1675], II Pr 15) by Stephan Schmid - Faculties in Early Modern Philosophy 3
     A reaction: This seems to imply that the mind lacks unity, and also lacks a Self. Spinoza doesn't say much about this view.
15. Nature of Minds / A. Nature of Mind / 7. Animal Minds
Animals are often observed to be wiser than people [Spinoza]
     Full Idea: Many things are observed in brutes which far surpass human sagacity.
     From: Baruch de Spinoza (The Ethics [1675], III Pr 02)
     A reaction: Lovely - especially in an age when animals were being actively downgraded (e.g. by Descartes) in order to upgrade man.
15. Nature of Minds / B. Features of Minds / 1. Consciousness / d. Purpose of consciousness
To understand is the absolute virtue of the mind [Spinoza]
     Full Idea: To understand is the absolute virtue of the mind.
     From: Baruch de Spinoza (The Ethics [1675], IV Pr 28)
     A reaction: A possible epigraph for this website. Perhaps it should be required by law that this be printed on the frontispiece of every philosophy book ever published.
15. Nature of Minds / C. Capacities of Minds / 1. Faculties
Faculties are either fictions, or the abstract universals of ideas [Spinoza]
     Full Idea: Faculties are either complete fictions, or nothing but metaphysical beings or universals, which are used to forming from particulars (as 'stoneness' is to a stone).
     From: Baruch de Spinoza (The Ethics [1675], II Pr 48S), quoted by Stephan Schmid - Faculties in Early Modern Philosophy 3
     A reaction: So they are, at best, the sources of our concepts. Does that mean one faculty for each concept, or one huge concept-generating faculty?
15. Nature of Minds / C. Capacities of Minds / 2. Imagination
Memory, senses and understanding are all founded on the imagination [Hume]
     Full Idea: The memory, senses, and understanding are all of them founded on the imagination, or the vivacity of our ideas.
     From: David Hume (Treatise of Human Nature [1739], I.IV.7.3), quoted by Stephan Schmid - Faculties in Early Modern Philosophy 5
     A reaction: He seems to have in mind his theory of associations, which are not rational.
15. Nature of Minds / C. Capacities of Minds / 7. Seeing Resemblance
Hume needs a notion which includes degrees of resemblance [Shoemaker on Hume]
     Full Idea: Hume needs a notion of resemblance where some things resemble a given thing more than other things do, and some may resemble exactly, and some hardly at all.
     From: comment on David Hume (Treatise of Human Nature, + Appendix [1740]) by Sydney Shoemaker - Causality and Properties §02
     A reaction: An astute and simple point. Once you admit degrees of resemblance, of course, then resemblance probably ceases to be a primitive concept in your system, and Hume would be well stuck.
General ideas are the connection by resemblance to some particular [Hume]
     Full Idea: All general ideas are nothing but particular ones, annexed to a certain term, which gives them a more extensive signification, and makes them recall upon occasion other individuals, which are similar to them.
     From: David Hume (Enquiry Conc Human Understanding [1748], I.VII.17), quoted by Edwin D. Mares - A Priori 08.2
     A reaction: This is close to Berkeley's idea that we can only grasp particulars. Personally I think the idea of (psychological) abstraction is unavoidable. Irrelevant features of particulars need to ignored.
A picture of a friend strengthens our idea of him, by resemblance [Hume]
     Full Idea: Upon the appearance of the picture of an absent friend, our idea of him is evidently enlivened by the resemblance.
     From: David Hume (Enquiry Conc Human Understanding [1748], V.II.41)
Hume does not distinguish real resemblances among degrees of resemblance [Shoemaker on Hume]
     Full Idea: Hume regarded the notion of resemblance as unproblematic, ..but any two objects share infinitely many Cambridge (whimsical relational) properties, and resemble in infinite ways. He needs real resemblance, which needs degrees of resemblance.
     From: comment on David Hume (Enquiry Conc Human Understanding [1748], V.II.41) by Sydney Shoemaker - Causality and Properties §2
     A reaction: [compressed] See Idea 191. We forgive Hume, because he is a pioneer, but this is obviously right. Draw a line between 'real' resemblances and rest will be tricky, and bad news for regularity accounts of laws and causation.
15. Nature of Minds / C. Capacities of Minds / 8. Remembering Contiguity
When I am close to (contiguous with) home, I feel its presence more nearly [Hume]
     Full Idea: When I am a few miles from home, whatever relates to it touches me more nearly than when I am two hundred leagues distance.
     From: David Hume (Enquiry Conc Human Understanding [1748], V.II.42)
If the body is affected by two things together, the imagining of one will conjure up the other [Spinoza]
     Full Idea: If the human body has once been affected by two or more bodies at the same time, when the mind afterwards imagines any of them, it will straightway remember the other also.
     From: Baruch de Spinoza (The Ethics [1675], II Pr 18)
     A reaction: Very interesting to see a great rationalist philosopher making an observation right at the heart of Hume's theory of knowledge (associationism). Clearly an associationist theory of psychology need not imply a materialist (connectionist) theory of mind.
15. Nature of Minds / C. Capacities of Minds / 9. Perceiving Causation
Our awareness of patterns of causation is too important to be left to slow and uncertain reasoning [Hume]
     Full Idea: Our inference of like effects from like causes is so essential to the subsistence of human creatures that it is unlikely to be trusted to the fallacious deductions of reasoning, which are slow, develop late, and are liable to error.
     From: David Hume (Enquiry Conc Human Understanding [1748], V.II.45)
An object made by a saint is the best way to produce thoughts of him [Hume]
     Full Idea: One of the best reliques which a devotee could procure would be the handiwork of a saint, because they were once at his disposal, and were moved and affected by him.
     From: David Hume (Enquiry Conc Human Understanding [1748], V.II.43)
15. Nature of Minds / C. Capacities of Minds / 10. Conatus/Striving
Our own force of persevering is nothing in comparison with external forces [Spinoza]
     Full Idea: The force by which a man perserveres in existing is limited, and infinitely surpassed by the power of external causes.
     From: Baruch de Spinoza (The Ethics [1675], IV Pr 03)
     A reaction: This states the obvious, but is important as a way of viewing things. I think Nietzsche's notion of Will to Power comes in here, as a unified account of both forces.
As far as possible, everything tries to persevere [Spinoza]
     Full Idea: Each thing, as far as it can by its own power, strives to persevere in its own being. ...[7] The striving by which each thing strives to persevere in its being is nothing but the actual essence of the thing.
     From: Baruch de Spinoza (The Ethics [1675], III Pr 06)
     A reaction: This is covered by his word 'conatus'. Obviously this covers plants as well as sentient beings. Mountains have no power to persevere. Since Spinoza sees this as basic, he is not far from Nietzsche.
The conatus (striving) of mind and body together is appetite, which is the essence of man [Spinoza]
     Full Idea: When striving [conatus] is related to the Mind it is called Will, but when related to the Mind and Body it is called Appetite. This Appetite is the essence of man, from whose nature there necessarily follow those things that promote this preservation.
     From: Baruch de Spinoza (The Ethics [1675], III Pr 09S), quoted by Stephan Schmid - Faculties in Early Modern Philosophy 3
     A reaction: Spinoza seems to see 'conatus' as a fairly unified thing, where Nietzsche sees the will to power as a combination of many competing 'drives'. I think Nietzsche is closer to the truth.
16. Persons / B. Nature of the Self / 5. Self as Associations
Hume's 'bundle' won't distinguish one mind with ten experiences from ten minds [Searle on Hume]
     Full Idea: Hume's thought that each perception is separate and distinct cannot be right, because then we can't distinguish between one consciousness with ten experiences and ten different consciousnesses.
     From: comment on David Hume (Treatise of Human Nature [1739]) by John Searle - Rationality in Action Ch.3.VI
     A reaction: Why can't the only connection between them be that they all occur to the speaker who reports to them? How would I know if one of 'my' mental events actually belonged to a neighbour and had strayed. If it was coherent, I would accept it.
A person is just a fast-moving bundle of perceptions [Hume]
     Full Idea: I affirm of the rest of mankind, that they are nothing but a bundle or collection of different perceptions, which succeed each other with an inconceivable rapidity, and are in perpetual flux and movement.
     From: David Hume (Treatise of Human Nature [1739], I.IV.6)
     A reaction: Note that Hume is not just saying what we can know of ourselves, but is asserting a view of what we actually are. The minimal objection to this is to ask how we know that a perception is a member of one big bundle rather than several small ones.
The parts of a person are always linked together by causation [Hume]
     Full Idea: Whatever changes a person endures, his several parts are still connected by the relation of causation.
     From: David Hume (Treatise of Human Nature [1739], I.IV.6)
     A reaction: However, the opposite ends of the universe are linked together by causation, so that will not suffice for a theory of personal identity. One might try to specify a complex and tight network of causation (like a brain!) instead of just 'connection'.
Hume gives us an interesting sketchy causal theory of personal identity [Perry on Hume]
     Full Idea: I believe Hume offers an interesting if sketchy theory of personal identity, a causal theory, disguised as the revolutionary discovery that there is no such thing as personal identity
     From: comment on David Hume (Treatise of Human Nature [1739], I.IV.6) by John Perry - Introduction to 'Personal Identity' Intro
     A reaction: There is certainly a theory there, even though Hume ceased to believe in it, which is nowadays covered by the idea that personal identity is a 'fiction', an arbitrary idea that reifies the focus and direction of a bundle of mental events.
A person is simply a bundle of continually fluctuating perceptions [Hume]
     Full Idea: [People] are nothing but a bundle or collection of different perceptions, which succeed each other with an inconceivable rapidity, and are in a continual flux and movement.
     From: David Hume (Treatise of Human Nature [1739], I.IV.6)
     A reaction: Nowadays we must say that this misses the huge non-conscious aspect of what a person is. He seems to see all mental events as equal. Isn't the experience of deciding to focus on this sentence more 'central' than awareness of your feet?
Experiences are logically separate, but factually linked by simultaneity or a feeling of continuousness [Ayer on Hume]
     Full Idea: Our experiences are logically independent, but they may be factually connected. What unites them is that either they are experienced together, or (if at separate times) they are separated by a stream of experience which is felt to be continuous.
     From: comment on David Hume (Treatise of Human Nature, + Appendix [1740], Bk 3 App.) by A.J. Ayer - The Central Questions of Philosophy §VI.A
     A reaction: A strict empiricist cannot deny that the feeling of continuity could be false, though that invites the Cartesian question of what exactly is experiencing the delusion. Hume denies that we experience any link between simultaneous experiences.
16. Persons / B. Nature of the Self / 7. Self and Body / a. Self needs body
The mind only knows itself by means of ideas of the modification of the body [Spinoza]
     Full Idea: The mind does not know itself, except in so far as it perceives the ideas of the modifications of the body.
     From: Baruch de Spinoza (The Ethics [1675], II Pr 29)
     A reaction: This is reminiscent of Hume's 'bundle of perceptions' report of introspection. It is in tune with a modern 'animalist' view of a person, and with a view of the mind as a map of the body and its environs. Is he a sceptic about personal identity?
16. Persons / C. Self-Awareness / 2. Knowing the Self
Self-knowledge needs perception of the affections of the body [Spinoza]
     Full Idea: The mind does not know itself except in so far as it perceives the ideas of the affections of the body.
     From: Baruch de Spinoza (The Ethics [1675], II Pr 23)
     A reaction: 'The ideas of the affections of the body' seems to be twice removed from the actual body, so I am not crystal clear what this says. The idea of knowing yourself with no involvement at all of the body seems absurd.
16. Persons / C. Self-Awareness / 3. Limits of Introspection
Introspection always discovers perceptions, and never a Self without perceptions [Hume]
     Full Idea: I never can catch myself at any time without a perception, and never can observe any thing but the perception.
     From: David Hume (Treatise of Human Nature [1739], I.IV.6)
     A reaction: The first half can hardly be denied, but I think the second half is just false. What you observe is not just a raw neutral sense-datum, floating in nothing, but a sense-datum that is deeply coloured by MY interests, interpretations and values.
16. Persons / D. Continuity of the Self / 2. Mental Continuity / a. Memory is Self
The poet who forgot his own tragedies was no longer the same man [Spinoza]
     Full Idea: Sometimes a man undergoes such changes that he cannot very well be said to be the same man, as was the case with a certain Spanish poet ...who was so oblivious of his past life that he did not believe the tales and tragedies he had composed were his own.
     From: Baruch de Spinoza (The Ethics [1675], IV Pr 39)
     A reaction: This seems to need Locke's distinction between 'man' and 'person', since the poor poet was clearly the same human being. Spinoza places huge emphasis on the intellect as the essence of the man.
Memory only reveals personal identity, by showing cause and effect [Hume]
     Full Idea: Memory does not so much produce as discover personal identity, by showing us the relation of cause and effect among our different perceptions.
     From: David Hume (Treatise of Human Nature [1739], I.IV.6)
     A reaction: This is a rather strained proposal, as the revelation of a network of cause and effect seems to have no implications for personal identity (unless only 'I' could be the cause).
We use memory to infer personal actions we have since forgotten [Hume]
     Full Idea: We can extend the chain of causes acquired from memory, and consequently the identity of our persons beyond our memory, and can comprehend times, and circumstances, and actions, which we have entirely forgot.
     From: David Hume (Treatise of Human Nature [1739], I.IV.6)
     A reaction: If the principle is just that 'I am my consciousness' (including of my past), then why should not my consciousness of other people's pasts by included in my identity. How do I know that images in my consciousness are MY memories?
Memory not only reveals identity, but creates it, by producing resemblances [Hume]
     Full Idea: The memory not only discovers the identity [of the mind], but also contributes to its production, by producing the relation of resemblance among the perceptions
     From: David Hume (Treatise of Human Nature [1739], I.IV.6)
     A reaction: This is Hume battling to explain personal identity by his principles of association. He discount 'contiguity'. He doesn't explain how memory creates resemblances. Is not resemblance of idea to fact required in order to remember?
Who thinks that because you have forgotten an incident you are no longer that person? [Hume]
     Full Idea: Who will affirm, because he has entirely forgot the incidents of past days, that the present self is not the same person with the self of that time? And by that means overturn all the most established notions of personal identity?
     From: David Hume (Treatise of Human Nature [1739], I.IV.6)
     A reaction: This is a swipe at one of Locke's most controversial claims (especially when applied to incidents of criminal behaviour). Hume says memory constitutes this identity, but Locke's view says it merely reveals identity.
16. Persons / D. Continuity of the Self / 2. Mental Continuity / b. Self as mental continuity
Causation unites our perceptions, by producing, destroying and modifying each other [Hume]
     Full Idea: As to causation, the true idea of the human mind is to consider it as a system of different perceptions, which are linked together by the relation of cause and effect, and mutually produce, destroy, influence and modify each other.
     From: David Hume (Treatise of Human Nature [1739], I.IV.6)
     A reaction: He suggests that the associations of memory and causation might be sufficient to produce identity of the mind, and he gives the priority to memory. Eventually the good empiricist despairs because you cannot experience the links.
Are self and substance the same? Then how can self remain if substance changes? [Hume]
     Full Idea: Is the self the same with substance? If it be, how can that question have place concerning the subsistence of self, under a change of substance? If they be distinct, what is the difference between them?
     From: David Hume (Treatise of Human Nature, + Appendix [1740], Appendix)
     A reaction: Locke seems to think there is a characterless substance which supports momories, and the latter constitute the self. So if my substance acquires Nestor's memories, I become Nestor. Hume, the stricter empiricist, cares nothing for characterless things.
16. Persons / D. Continuity of the Self / 2. Mental Continuity / c. Inadequacy of mental continuity
Perceptions are distinct, so no connection between them can ever be discovered [Hume]
     Full Idea: If perceptions are distinct existences, they form a whole only by being connected together. But no connexions among distinct existences are ever discoverable. We only feel a connexion ...to pass from one object to another.
     From: David Hume (Treatise of Human Nature, + Appendix [1740], Appendix)
     A reaction: This first part of this is a problem for any 'bundle' theory of objects or self. This is why Hume abandons all hope for his theory of personal identity based on association. You infer the associations, but don't perceive them.
16. Persons / E. Rejecting the Self / 4. Denial of the Self
A continuous lifelong self must be justified by a single sustained impression, which we don't have [Hume]
     Full Idea: If any impression gives rise to the idea of self, that impression must continue invariably the same, through the whole course of our lives; since self is supposed to exist after that manner. But there is no impression constant and invariable.
     From: David Hume (Treatise of Human Nature [1739], I.IV.6)
     A reaction: This is a rather dogmatic application of the requirement that all knowledge must be founded in experience. It fails to recognise that knowledge of the thing having the experiences is a rather special case. We must ask for the best explanation.
When I introspect I can only observe my perceptions, and never a self which has them [Hume]
     Full Idea: When I enter most intimately into myself I always stumble on some particular perception or other, of heat or cold, love or hatred, pain or pleasure. I never can catch myself at any time without a perception, and never observe any thing but the perception.
     From: David Hume (Treatise of Human Nature [1739], I.IV.6)
     A reaction: It isn't like looking for your car in the car park. The prior question should be: assuming you do have a persisting self, what would you expect introspection to reveal about it?
We pretend our perceptions are continuous, and imagine a self to fill the gaps [Hume]
     Full Idea: We feign the continued existence of the perceptions of our senses, to remove their interruption; and run into the notion of a soul, and self, and substance, to disguise the variation.
     From: David Hume (Treatise of Human Nature [1739], I.IV.6)
     A reaction: Modern neuroscience (according to Dennett) endorses this, because the brain continually fills in gaps in experience (as it fills in the blindspot during normal vision).
Identity in the mind is a fiction, like that fiction that plants and animals stay the same [Hume]
     Full Idea: The identity we ascribe to the mind is only a fictitious one, and of a like kind with that we ascribe to vegetable and animal bodies. It cannot therefore have a different origin, but must proceed from a like operation of the imagination upon like objects.
     From: David Hume (Treatise of Human Nature [1739], I.IV.6)
     A reaction: Sustained purpose is Hume's common factor. Is the identity over time ascribed to the body of a single animal nothing more than a fiction? It is a wise ascription, compared to stupid ascriptions to gerrymandered objects.
We have no impression of the self, and we therefore have no idea of it [Hume]
     Full Idea: Every idea is derived from preceding impressions; and we have no impression of self or substance, as something simple and individual. We have, therefore, no idea of them in that sense.
     From: David Hume (Treatise of Human Nature, + Appendix [1740], Appendix)
     A reaction: This spells out with beautiful simplicity how his empiricist assumptions lead him to this sceptical view. No logical positivist could reject this thought. Personally I favour empiricism with added inference to the best explanation.
Does an oyster with one perception have a self? Would lots of perceptions change that? [Hume]
     Full Idea: Suppose an oyster to have only one perception, as of thirst or hunger. Do you consider any thing but merely that perception? Have you any notion of self or substance? If not, the addition of other perceptions can never give you that notion.
     From: David Hume (Treatise of Human Nature, + Appendix [1740], Appendix)
     A reaction: A splendid addition to his earlier sceptical thinking. We could form a different conclusion. Suppose I do have a self. If my multitudinous perceptions were reduced to a single perception of agonising pain, would that remove the self?
16. Persons / F. Free Will / 1. Nature of Free Will
A thing is free if it acts by necessity of its own nature, and the act is determined by itself alone [Spinoza]
     Full Idea: That thing is called free which exists solely by the necessity of its own nature, and of which the action is determined by itself alone.
     From: Baruch de Spinoza (The Ethics [1675], I Def 7)
     A reaction: This points to the obvious thought that nothing is independent enough to achieve freedom. Our concept of nature is of almost endless interdependence. God seems the only thing that could possibly qualify, though some might say humans could.
16. Persons / F. Free Will / 2. Sources of Free Will
People are only free if they are guided entirely by reason [Spinoza]
     Full Idea: The only genuinely free person is one who lives with his entire mind guided solely by reason.
     From: Baruch de Spinoza (Tractatus Theologico-Politicus [1670], 16.10)
     A reaction: It strikes me as blatantly impossible to be entirely guided by reason. His point is that it is a subservience to reason which is entirely chosen. Why is that different from choosing to be entirely subservient to another person?
16. Persons / F. Free Will / 5. Against Free Will
A thing is free if it acts only by the necessity of its own nature [Spinoza]
     Full Idea: I say that a thing is free, which exists and acts solely by the necessity of its own nature.
     From: Baruch de Spinoza (Letter to G.H. Schaller [1674], 1674.10)
     A reaction: Of course, this isn't 'freedom' at all, but it seems to exactly right as an account of so-called freedom. In the case of a human being the 'necessity of our own nature' is character, and virtue and vice are the expressions of the necessities of character.
An act of will can only occur if it has been caused, which implies a regress of causes [Spinoza]
     Full Idea: Each volition can neither exist nor be determined to produce an effect unless it is determined by another cause, and this cause again by another, and so on, to infinity.
     From: Baruch de Spinoza (The Ethics [1675], I Pr 32), quoted by Stephan Schmid - Faculties in Early Modern Philosophy 3
     A reaction: Acts of will are usually responses to situations, so it seems a bit simplistic to think that they are all spontaneous sui generis causal events. That argument won't work, of course, for a random volition that is out of context.
'Free will' is a misunderstanding arising from awareness of our actions, but ignorance of their causes [Spinoza]
     Full Idea: Men are mistaken in thinking themselves free; their opinion is made up of consciousness of their own actions, and ignorance of the causes by which they are conditioned.
     From: Baruch de Spinoza (The Ethics [1675], II Pr 35)
     A reaction: I have recently come to totally agree with this. The whole concept of free will seems to me incoherent, and Spinoza pinpoints the error. We aren't equipped to know the origins of the thoughts that arrive in our consciousnesses.
Would we die if we lacked free will, and were poised between equal foods? Yes! [Spinoza]
     Full Idea: It may be objected, if a man does not act from free will, what will happen if the incentives to action are equally balanced, as in the case of Buridan's ass? Will he perish of hunger and thirst. ..Personally I am ready to admit that he would die.
     From: Baruch de Spinoza (The Ethics [1675], II Pr 49)
     A reaction: A nicely defiant way of demonstrating his rejection of free will. I have to agree with him. Even if there were such a thing as 'free will', it is hard to see how it could act as a tie-breaker. Which way would it freely decide?
The mind is not free to remember or forget anything [Spinoza]
     Full Idea: It is not within the free power of the mind to remember or forget a thing at will.
     From: Baruch de Spinoza (The Ethics [1675], III Pr 02)
     A reaction: An interesting little corrective if you were thinking that your total control over you mind proved that you had free will. Once you face up to your lack of control of the memory process, you begin to realise how little of your mind even feels controlled.
The doctrine of free will arises from a false sensation we have of freedom in many actions [Hume]
     Full Idea: The prevalence of the doctrine of liberty may be accounted for from a false sensation or seeming experience which we have, or may have, of liberty or indifference, in many of our actions.
     From: David Hume (Enquiry Conc Human Understanding [1748], VIII.I.72)
16. Persons / F. Free Will / 6. Determinism / a. Determinism
We think we are free because we don't know the causes of our desires and choices [Spinoza]
     Full Idea: Men think themselves free because they are conscious of their volitions and their appetites, yet never give a thought to the causes which dispose them to desire or to exercise the will as they do, since they are wholly unaware of them.
     From: Baruch de Spinoza (The Ethics [1675])
     A reaction: This encapsulates the determinist idea nicely. In the end we just choose, but we have no idea why we prefer one reason to another, or simply opt for one thing rather than another.
The actual world is the only one God could have created [Spinoza]
     Full Idea: Things could not have been brought into being by God in any manner or in any order different from that which has in fact obtained.
     From: Baruch de Spinoza (The Ethics [1675], I Pr 33)
     A reaction: Said to be a "notorious" proposition. This is a key idea in philosophy because it represents (like solipsism) one of the extremes - there is no such thing as contingency, and that all things are necessary. It is daft not to take Spinoza seriously on this.
16. Persons / F. Free Will / 7. Compatibilism
Liberty is merely acting according to the will, which anyone can do if they are not in chains [Hume]
     Full Idea: By liberty we can only mean a power of acting or not acting according to the determinations of the will, …which is universally allowed to everyone who is not a prisoner and in chains.
     From: David Hume (Enquiry Conc Human Understanding [1748], VIII.I.73)
Hume makes determinism less rigid by removing the necessity from causation [Trusted on Hume]
     Full Idea: Hume's account of the causal relation makes determinism less rigid because there is no longer a logical necessity in the succession of events.
     From: comment on David Hume (Enquiry Conc Human Understanding [1748], VIII.II.75) by Jennifer Trusted - Free Will and Responsibility Ch.4
17. Mind and Body / A. Mind-Body Dualism / 5. Parallelism
Ideas and things have identical connections and order [Spinoza]
     Full Idea: The order and connection of ideas is the same as the order and connection of things.
     From: Baruch de Spinoza (The Ethics [1675], II Pr 07)
     A reaction: I hadn't registered until Beth Lord pointed it out that this is Spinoza's parallelism of the mental and the physicalism, which seems to be roughly the same as the views of Leibniz and Malebranche, but with a different explanation.
17. Mind and Body / A. Mind-Body Dualism / 8. Dualism of Mind Critique
Mind and body are one thing, seen sometimes as thought and sometimes as extension [Spinoza]
     Full Idea: The mind and the body are one and the same individual which is conceived now under the attribute of thought, now under the attribute of extension.
     From: Baruch de Spinoza (The Ethics [1675])
     A reaction: I suppose we might now call this 'property dualism'. It is odd that when you examine one property, the other is nowhere to be seen.
We are incapable of formulating an idea which excludes the existence of our body [Spinoza]
     Full Idea: An idea which excludes the existence of our body cannot be postulated in our mind, but is contrary thereto.
     From: Baruch de Spinoza (The Ethics [1675], III Pr 10)
     A reaction: A fascinating claim. At the heart of Descartes is an unspoken thought experiment exploring the possibility of a disembodied mind. This is a beautiful challenge to the very concept of such a thing, and points to a grealty superior theory of mind.
17. Mind and Body / E. Mind as Physical / 1. Physical Mind
Mind and body are the same thing, sometimes seen as thought, and sometimes as extension [Spinoza]
     Full Idea: The idea of body and body, that is, mind and body, are one and the same individual conceived now under the attribute of thought, now under the attribute of extension.
     From: Baruch de Spinoza (The Ethics [1675], II Pr 21)
     A reaction: This is an appealingly modern view, but a bit glib. Phenomenologically, the mind seen as thought and the body seen as extension are about as wildly different as it is possible to be. This needs explanation.
18. Thought / A. Modes of Thought / 3. Emotions / a. Nature of emotions
Emotion is a modification of bodily energy, controlling our actions [Spinoza]
     Full Idea: By emotion [affectus] I understand the modification of energy of the body by which the power of action is aided or restrained.
     From: Baruch de Spinoza (The Ethics [1675]), quoted by Robert C. Solomon - The Passions 3.4
     A reaction: [no ref given] Solomon gives this as the earliest version of the 'hydraulic' model of emotions, later found in Freud and Jung. Very unusual to give a wholly physical account of these psychic states.
18. Thought / A. Modes of Thought / 3. Emotions / e. Basic emotions
The three primary emotions are pleasure, pain, and desire [Spinoza, by Goldie]
     Full Idea: Spinoza held that the three primary emotions are pleasure, pain, and desire
     From: report of Baruch de Spinoza (The Ethics [1675], III P59) by Peter Goldie - The Emotions 4 'Evidence'
     A reaction: If you are aiming for a minimal list, this is quite good. One active, one good passive, one bad passive. Output and input.
The three primary emotions are pleasure, pain and desire [Spinoza]
     Full Idea: I recognise only three primitive or primary emotions, namely, pleasure, pain and desire.
     From: Baruch de Spinoza (The Ethics [1675], IIIEm Df 4)
     A reaction: Interesting, but hard to justify. Presumably one can analyse fear as desire for no pain, and grief as desire for the return of pleasure, etc. It is a nice exercise in introspective psychology, but I don't feel much wiser for it.
18. Thought / A. Modes of Thought / 3. Emotions / f. Emotion and reason
Minds are subject to passions if they have inadequate ideas [Spinoza]
     Full Idea: The mind is subject to passions in proportion to the number of inadequate ideas which it has.
     From: Baruch de Spinoza (The Ethics [1675], III Pr 01)
     A reaction: An exceptionally intellectualist view of emotions!
An emotion is only bad if it hinders us from thinking [Spinoza]
     Full Idea: An emotion is only bad or hurtful, in so far as it hinders the mind from being able to think.
     From: Baruch de Spinoza (The Ethics [1675], V Pr 09)
     A reaction: This sounds sensible. It fits Spinoza's quasi-stoicism that he should be happy with emotion (as natural), but also that true 'living by nature' requires control by reason. Only a wild romantic would think emotion better than judgement as a guide.
18. Thought / A. Modes of Thought / 3. Emotions / g. Controlling emotions
Stoics want to suppress emotions, but Spinoza overcomes them with higher emotions [Spinoza, by Stewart,M]
     Full Idea: Spinoza says the only way to overcome emotions is with higher emotions, thus distinguishing himself from the Stoics, who argued that the only thing to do with the surly crowd of human emotions is to have them all shot.
     From: report of Baruch de Spinoza (The Ethics [1675]) by Matthew Stewart - The Courtier and the Heretic Ch.10
     A reaction: The modern view would certainly be that the Stoics were responsible for massive problems in European civilization (thought the Buddhist have similar views). Emotions are now seen as integral even to very pure reasoning.
An emotion comes more under our control in proportion to how well it is known to us [Spinoza]
     Full Idea: An emotion becomes more under our control, and the mind is less passive in respect to it, in proportion as it is more known to us.
     From: Baruch de Spinoza (The Ethics [1675], V Pr 03)
     A reaction: This may sound a little optimistic, but it is also obviously true, in the sense that the only proper control we have of our own behaviour is through thought and judgement, which presuppose awareness of what needs controlling.
18. Thought / A. Modes of Thought / 6. Judgement / b. Error
People make calculation mistakes by misjudging the figures, not calculating them wrongly [Spinoza]
     Full Idea: When men make mistakes in calculation, they have one set of figures in their mind, and another on the paper. If we could see into their minds, they do not make a mistake.
     From: Baruch de Spinoza (The Ethics [1675], II Pr 47)
     A reaction: A wonderfully optimistic assertion of faith in reason! He seems to imply an infallibility in reason, which seems a bit implausible. If I make 7+6=14, MUST I have muddled the 6 with a 7? Presumably Spinoza was good at arithmetic.
18. Thought / C. Content / 2. Ideas
An idea involves affirmation or negation [Spinoza]
     Full Idea: An idea, insofar as it is an idea, involves an affirmation or negation.
     From: Baruch de Spinoza (The Ethics [1675], II Pr 49 sII)
     A reaction: Spinoza clearly distinguishes ideas from images, and here seems to identify ideas with propositions. Nowadays we say these are 'true or false', but Spinoza is more personal and psychological. I prefer his way of putting it.
An 'idea' is a mental conception which is actively formed by the mind in thinking [Spinoza]
     Full Idea: By 'idea', I mean the mental conception which is formed by the mind as a thinking thing (this is not a passive perception with regard to the object, but expresses an activity of the mind).
     From: Baruch de Spinoza (The Ethics [1675], II Def 3)
     A reaction: This is interesting as a seventeenth century attempt to grapple with the nature of thought. Spinoza sees it as of the essence of mind, since it is what the mind contributes, rather than what happens to the mind when it experiences.
Ideas are powerful entities, which can produce further ideas [Spinoza, by Schmid]
     Full Idea: Spinoza conceives of ideas as intrinsically powerful entities, which have a capacity to produce further ideas.
     From: report of Baruch de Spinoza (The Ethics [1675]) by Stephan Schmid - Faculties in Early Modern Philosophy 6
     A reaction: Is the idea the source of the entire philosophy of Hegel? I find Hegel's claim to infer huge chains of ideas from very simple origins quite implausible. I also rather doubt whether a wholly isolated idea can produce a further idea.
Ideas are not images formed in the brain, but are the conceptions of thought [Spinoza]
     Full Idea: By ideas I do not mean images such as are formed at the back of the eye, or in the midst of the brain, but the conceptions of thought.
     From: Baruch de Spinoza (The Ethics [1675], II Pr 48)
     A reaction: This appears to be equating 'ideas' with what we now call 'concepts', which presumably makes Spinoza less open to criticism than other philosophers of his time, for postulating baffling mental copies of the world.
20. Action / A. Definition of Action / 2. Duration of an Action
If one event causes another, the two events must be wholly distinct [Hume, by Wilson/Schpall]
     Full Idea: Hume's maxim is that if one event cause another, then the two events must be wholly distinct.
     From: report of David Hume (Treatise of Human Nature [1739]) by Wilson,G/Schpall,S - Action 3
     A reaction: [Anyone know the original reference?] So we are not allowed to say that one part of an event caused another. The charged caused the victory, so they are two events, but in another context the whole battle is one event.
20. Action / B. Preliminaries of Action / 2. Willed Action / a. Will to Act
Claiming that actions depend on the will is meaningless; no one knows what the will is [Spinoza]
     Full Idea: Saying that human actions depend on the will is a mere phrase without any idea to correspond to. What the will is, and how it moves the body, no one knows.
     From: Baruch de Spinoza (The Ethics [1675], II Pr 35)
     A reaction: As so often, the rationalist Spinoza agrees with many empiricists about this one. If there is no such thing as the will, then there isn't much prospect of it being free, thought one might talk about 'freedom of thought' instead.
Only experience teaches us about our wills [Hume]
     Full Idea: We learn the influence of our will from experience alone.
     From: David Hume (Enquiry Conc Human Understanding [1748], VII.I.52)
     A reaction: I can, of course, produce inductive generalisations about what my will can achieve, based on some limited experiences. "I know I can master that". Hobbes (and others) say we have no experience of a 'will'. Hume should be more sceptical!
Spinoza argues that in reality the will and the intellect are 'one and the same' [Spinoza, by Cottingham]
     Full Idea: Spinoza argues that in reality the will and the intellect are 'one and the same'.
     From: report of Baruch de Spinoza (The Ethics [1675]) by John Cottingham - The Rationalists p.159
     A reaction: The 'will' is certainly a dubious concept, though it seems involved with desire and actual. In a sense, I suppose, all pursuits of reason are acts of will.
20. Action / C. Motives for Action / 1. Acting on Desires
Whenever we act, then desire is our very essence [Spinoza]
     Full Idea: Desire is man's very essence, insofar as it is agreed to be determined, from any affection of it, to do something. ...Desire is appetite, together with the consciousness of it.
     From: Baruch de Spinoza (The Ethics [1675], III Def of Aff I)
     A reaction: [I think that is the gist of it!] This sounds a bit circular, but seems to say that actions are almost entireoy the expression of desires.
20. Action / C. Motives for Action / 3. Acting on Reason / a. Practical reason
For Hume, practical reason has little force, because we can always modify our desires [Hume, by Graham]
     Full Idea: In Hume's account of action, practical reason is not a very forceful guide to conduct, since we can escape its demands by abandoning or modifying our desires.
     From: report of David Hume (Treatise of Human Nature [1739]) by Gordon Graham - Eight Theories of Ethics Ch.6
     A reaction: Presumably a desire can be a good reason, and we can passionately desire to be rational, etc., so this is a rather complex issue. 'Pure reason' is not 'all-or-nothing', and neither is pure desire.
20. Action / C. Motives for Action / 3. Acting on Reason / b. Intellectualism
Reason alone can never be a motive to any action of the will [Hume]
     Full Idea: Reason alone can never be a motive to any action of the will.
     From: David Hume (Treatise of Human Nature [1739], II.III.3)
     A reaction: This is Hume's notorious total rejection of Socratic intellectualism, a stilleto in the back of the 'age of reason'. Hume thinks desire is the motivator. He's probably right. Why should truth motivate? See Idea 4421.
20. Action / C. Motives for Action / 4. Responsibility for Actions
We love or hate people more strongly because we think they are free [Spinoza]
     Full Idea: Because men consider themselves to be free, they have a greater love or hate toward one another than toward other things.
     From: Baruch de Spinoza (The Ethics [1675], III Pr 49S)
     A reaction: A very penetrating remark. If we abandon the concept of free will, I suspect that we will all become much more easy-going and tolerant, but the thought that feelings of love might also decline is a sobering one.
We are the source of an action if only our nature can explain the action [Spinoza]
     Full Idea: I say that we act when anything is done, either within us or without us, of which we are the adequate cause, that is to say, when from our nature anything follows which by that nature alone can be clearly and distinctly understood.
     From: Baruch de Spinoza (The Ethics [1675], III Def 2)
     A reaction: I like that one a lot. The point is to get a concept of responsibility that doesn't need free will, and to distinguish the thief from the kleptomaniac. Does kleptomania derive from a person's true nature? Essentialism in action.
We act when it follows from our nature, and is understood in that way [Spinoza]
     Full Idea: We act when something in us or outside us follows from our nature, which can be clearly and distinctly understood through this alone.
     From: Baruch de Spinoza (The Ethics [1675], III Def2)
     A reaction: I like this, because it links actions to our essential natures, and because it focuses on understanding the action, which must involve explaining the action. This is the root of responsibility, not something called 'free will'. BUT SEE 17202.
You can only hold people responsible for actions which arise out of their character [Hume]
     Full Idea: Where actions proceed not from some cause in the characters and dispositions of the person who performed them, they infix not themselves upon him, and can neither redound to his honour if good, nor infamy if evil. The action in itself may be blameable.
     From: David Hume (Treatise of Human Nature [1739], II.III.2), quoted by Philippa Foot - Free Will as Involving Determinism p.70
     A reaction: I agree with Foot that this is wrong. Uncharacteristic actions still reflect on the person. The last sentence is wrong too. If you ignore the agent of an action, it can't be distinguished from a flash of lightning.
Praise and blame can only be given if an action proceeds from a person's character and disposition [Hume]
     Full Idea: Where actions proceed not from some cause in the character and disposition of the person who performed them, they can neither redound to his honour, if good, nor his infamy, if evil.
     From: David Hume (Enquiry Conc Human Understanding [1748], VIII.I.76)
20. Action / C. Motives for Action / 5. Action Dilemmas / a. Dilemmas
Moral questions can only be decided by common opinion [Hume]
     Full Idea: Though an appeal to general opinion may justly, in the speculative sciences of metaphysics, natural philosophy or astronomy, be deemed unfair, yet in all questions with regard to morals there is really no other standard for deciding controversies.
     From: David Hume (Of the original contract [1741], p.291)
     A reaction: Surely this is too pessimistic. Common opinion decided to burn people to death for being witches. Common opinion may usually win, but there must sometimes be good grounds for resisting it.
21. Aesthetics / A. Aesthetic Experience / 2. Aesthetic Attitude
Forget about beauty; just concentrate on the virtues of delicacy and discernment admired in critics [Hume, by Scruton]
     Full Idea: Hume suggest we get away from the fruitless discussion of beauty, and simply concentrate on the qualities we admire, and ought to admire, in a critic - qualities such as delicacy and discernment.
     From: report of David Hume (Of the standard of taste [1757]) by Roger Scruton - Beauty: a very short introduction 6
     A reaction: We might wonder how you can admire 'discernment' without some view of the thing being discern, which is in danger of being beauty. How do you judge delicacy and discernment without judging the objects of the critic's taste? Mere authority?
21. Aesthetics / A. Aesthetic Experience / 3. Taste
Strong sense, delicate sentiment, practice, comparisons, and lack of prejudice, are all needed for good taste [Hume]
     Full Idea: Strong sense, united to delicate sentiment, improved by practice, perfected by comparison, and cleared of all prejudice, can alone entitle critics to the valuable character of having 'taste'.
     From: David Hume (Of the standard of taste [1757]), quoted by Robert Fogelin - Walking the Tightrope of Reason Ch.6
     A reaction: I agree entirely with this, but then I am a very politically incorrect elitist when it comes to taste. It just seems screamingly obvious that professional wine-tasters have a better appreciation of wine than me, and so on for the rest of the arts.
21. Aesthetics / A. Aesthetic Experience / 5. Natural Beauty
The most beautiful hand seen through the microscope will appear horrible [Spinoza]
     Full Idea: The most beautiful hand seen through the microscope will appear horrible.
     From: Baruch de Spinoza (Letters to Hugo Boxel [1674], 1674?)
     A reaction: Spinoza offers this nicely expressed point to support his view that beauty is strictly relative to observers, but I am unconvinced. If the outline of the hand is its key aesthetic feature, the viewer through the microscope cannot see it.
22. Metaethics / A. Ethics Foundations / 1. Nature of Ethics / f. Ethical non-cognitivism
Whether nature is beautiful or orderly is entirely in relation to human imagination [Spinoza]
     Full Idea: I do not attribute to nature either beauty or deformity, order or confusion. Only in relation to our imagination can things be called beautiful or deformed, ordered or confused.
     From: Baruch de Spinoza (Letters to Oldenburg [1665], 1665?)
     A reaction: This is clearly a statement of Hume's famous later opinion that there are no values ('ought') in nature ('is'). It is a rejection of Aristotelian and Greek teleology. It is hard to argue with, but I have strong sales resistance, rooted in virtue theory.
22. Metaethics / A. Ethics Foundations / 1. Nature of Ethics / g. Moral responsibility
If you deny all necessity and causation, then our character is not responsible for our crime [Hume]
     Full Idea: According to the principle which denies necessity, and consequently causes, a man is pure and unattainted after having committed the most horrid of crimes, since his actions are not derived from his character.
     From: David Hume (Enquiry Conc Human Understanding [1748], VIII.I.76)
     A reaction: The idea that responsibility involves actions which are 'derived from his character' strikes me as good. Once you give up free will, it is almost the only sensible way to go.
Repentance gets rid of guilt, which shows that responsibility arose from the criminal principles in the mind [Hume]
     Full Idea: Repentance and reformation can wipe off every crime, but that is because criminal acts prove criminal principles in the mind, so alteration of these principles removes that proof, and the acts cease to be criminal.
     From: David Hume (Enquiry Conc Human Understanding [1748], VIII.I.76)
     A reaction: A bit overstated, because a heinous crime will always taint our impression of someone's character. The person may cease to be criminal, but surely not the original acts?
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / b. Rational ethics
Men only agree in nature if they are guided by reason [Spinoza]
     Full Idea: Only insofar as men live according to the guidance of reason, must they always agree in nature.
     From: Baruch de Spinoza (The Ethics [1675], IV Pr 35)
     A reaction: A nice expression of the guiding idea of the Enlightenment - that consensus is the defining characteristic of rationality. Spinoza's politics emerges from this idea.
We seek our own advantage, and virtue is doing this rationally [Spinoza]
     Full Idea: Acting absolutely from virtue is nothing else in us but acting, living, and preserving our being (these three signify the same thing) by the guidance of reason, from the foundation of seeking one's own advantage.
     From: Baruch de Spinoza (The Ethics [1675], IV Pr 24)
     A reaction: The influence of stoicism is obvious here, that we live according to our nature, but our nature is rational. Spinoza doesn't seem to understand the pure altruism of lovers and parents.
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / e. Human nature
The essence of man is modifications of the nature of God [Spinoza]
     Full Idea: The essence of man consists of certain modifications of the attributes of God.
     From: Baruch de Spinoza (The Ethics [1675], II Pr 10)
     A reaction: Not an idea you hear much these days!
By 'good' I mean what brings us ever closer to our model of human nature [Spinoza]
     Full Idea: By 'good' I understand everything which we are certain is a means by which we may approach nearer and nearer to the model of human nature we set before us.
     From: Baruch de Spinoza (The Ethics [1675], IV Pref)
     A reaction: Unusual, and I'm not sure I understand it. His ideal largely concerns the intellect ruling the emotion
Along with his pantheism, Spinoza equates ethics with the study of human nature [Spinoza, by MacIntyre]
     Full Idea: The counterpart of understanding God as identical with Nature is understanding ethics as the study not of divine precepts but of our own nature and of what necessarily moves us.
     From: report of Baruch de Spinoza (The Ethics [1675]) by Alasdair MacIntyre - A Short History of Ethics Ch.10
     A reaction: As stated here, this seems wrong. We should approach ethics through Aristotle, but not through Freud. That is, virtues can be inferred from human nature, but the actual facts of human nature may be grubby and unpalatable.
If infancy in humans was very rare, we would consider it a pitiful natural defect [Spinoza]
     Full Idea: If a number of human beings were born adult, and only a few here and there were born infants, everyone would pity the infants, because we should then consider infancy not as a thing natural and necessary, but as a defect or fault of nature.
     From: Baruch de Spinoza (The Ethics [1675], V Pr 06)
     A reaction: A lovely example of the new objectivity about human beings that emerged in the Enlightenment. He could have said the same about old age.
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / h. Expressivism
We cannot discover vice by studying a wilful murder; that only arises from our own feelings [Hume]
     Full Idea: Examine wilful murder and see if you can find the matter of fact called vice. You only find certain passions, motives, volitions and thoughts. There is no matter of fact in the case. You can never find it till you turn your reflexion into your own breast.
     From: David Hume (Treatise of Human Nature [1739], III.I.2), quoted by Philippa Foot - Hume on Moral Judgement p.77
     A reaction: [...In you breast you find 'disapprobation'] The question Foot asks is whether the facts of the case are relevant to the disapprobation. If they are not, as Hume implies, then it would be rational to feel the same disapprobation about drinking coffee.
22. Metaethics / B. Value / 1. Nature of Value / b. Fact and value
Modern science has destroyed the Platonic synthesis of scientific explanation and morality [Hume, by Taylor,C]
     Full Idea: From our modern perspective, the Platonic synthesis of scientific explanation and moral insight lies irrecoverably shattered by the rise of natural science.
     From: report of David Hume (Treatise of Human Nature [1739]) by Charles Taylor - Sources of the Self §3.2
     A reaction: Modern attempts to challenge Hume's separation of fact from value have failed, but a return to the Greek perspective presents a plausible alternative.
The problem of getting to 'ought' from 'is' would also apply in getting to 'owes' or 'needs' [Anscombe on Hume]
     Full Idea: Hume's objection to passing from 'is' to 'ought' would equally apply to passing from 'is' to 'owes' or from 'is' to 'needs'.
     From: comment on David Hume (Treatise of Human Nature [1739]) by G.E.M. Anscombe - Modern Moral Philosophy p.176
     A reaction: Profound and important. The empirical and emotivist (nay, nihilist) clinging to the total independence of duties from facts crumbles when looking at facts of human nature or of social groups. Creatures ought to feed; societies ought to flourish.
You can't move from 'is' to 'ought' without giving some explanation or reason for the deduction [Hume]
     Full Idea: In many writers I find that instead of the usual propositions 'is' and 'is not', I then find no proposition that is not connected with an 'ought' or an 'ought not'. It is necessary that a reason be given for how one can be a deduction from the other.
     From: David Hume (Treatise of Human Nature [1739], III.1.1)
     A reaction: A huge claim, the basis of the value-free modern scientific world view. Possible escapes are Greek virtue theory, or Kantian principles, or some sort of a priori values (as in Charles Taylor).
Virtues and vices are like secondary qualities in perception, found in observers, not objects [Hume]
     Full Idea: Vice and virtue may be compared to sounds, colours, heat and cold, which, according to modern philosophy, are not qualities in objects but perceptions in the mind.
     From: David Hume (Letters [1739], to Hutcheson 1740)
     A reaction: Very revealing about the origin of the is/ought idea, but this is an assertion rather than an argument. Most Greeks treat value as a primary quality of things (e.g. life, harmony, beauty, health).
22. Metaethics / B. Value / 1. Nature of Value / d. Subjective value
We don't want things because they are good; we judge things to be good because we want them [Spinoza]
     Full Idea: In no case do we strive for, wish for, long for, or desire anything, because we deem it to be good, but on the other hand we deem a thing to be good, because we strive for it, wish for it, long for it, or desire it.
     From: Baruch de Spinoza (The Ethics [1675], III Pr 09)
     A reaction: Shocking, coming from a leading rationalist philosopher. It sounds more like Hume. Surely rationalism should put our capacity for judgement centre-stage? But Spinoza was a determinist. Is Kantian freedom of judgement required? Deterministic judgement?
22. Metaethics / B. Value / 2. Values / f. Altruism
The human heart has a natural concern for public good [Hume]
     Full Idea: While the human heart is compounded of the same elements as at present, it will never be wholly indifferent to public good.
     From: David Hume (Enquiry concerning Principles of Morals [1751], IX.I.222)
     A reaction: Even criminals can be patriotic. Why do people dump rubbish in beauty spots?
22. Metaethics / B. Value / 2. Values / g. Love
Love is nothing else but pleasure accompanied by the idea of an external cause [Spinoza]
     Full Idea: Love is nothing else but pleasure accompanied by the idea of an external cause.
     From: Baruch de Spinoza (The Ethics [1675], III Pr 13)
     A reaction: Not a definition to give us inspirational guidance! Sounds like grumpy old Hobbes. This is the 'love' of a heroin addict for a syringe. Personally I see love as having a rational aspect, which puts it 'under the aspect of eternity' (as Spinoza said!).
We have no natural love of mankind, other than through various relationships [Hume]
     Full Idea: It may be affirm'd, that there is no such passion in human minds, as the love of mankind, merely as such, independent of personal qualities, of services, or of relation to ourself.
     From: David Hume (Treatise of Human Nature, + Appendix [1740], p.481), quoted by John Kekes - Against Liberalism 9.4
     A reaction: Hume says this is for the best. I can't imagine spontaneous love of human beings we have never met. It takes the teachings of some sort of doctrine - religious or political - to produce such an attitude. I see it as a distortion of love. A hijacking.
Love is joy with an external cause [Spinoza]
     Full Idea: Love is joy with the accompanying idea of an external cause
     From: Baruch de Spinoza (The Ethics [1675], IV Pr 44)
     A reaction: This doesn't seem to quite capture the pain that some people find in love.
22. Metaethics / B. Value / 2. Values / i. Self-interest
Spinoza names self-interest as the sole source of value [Spinoza, by Stewart,M]
     Full Idea: Spinoza names self-interest as the sole source of value.
     From: report of Baruch de Spinoza (The Ethics [1675]) by Matthew Stewart - The Courtier and the Heretic Ch.10
     A reaction: This looks like a very seventeenth century view. There was a steady move from cynicism through to the optimism of the eighteenth century. I just don't agree that self-interest is the "sole" source of value, though we should never underestimate it.
Total selfishness is not irrational [Hume]
     Full Idea: It is not contrary to reason to prefer the destruction of the whole world to the scratching of my finger.
     From: David Hume (Treatise of Human Nature [1739], II.III.ii)
     A reaction: A famous idea, and the embodiment of moral nihilism. I say nothing could ever refute someone who held such a view. No moral theory can force someone to care, if they just don't.
22. Metaethics / B. Value / 2. Values / j. Evil
If our ideas were wholly adequate, we would have no concept of evil [Spinoza]
     Full Idea: If the human mind had none but adequate ideas, it would form no notion of evil.
     From: Baruch de Spinoza (The Ethics [1675], IV Pr 64)
     A reaction: There is some sort of notion of the wholly rational and benign community here, where living well is the single communal thought. It's sort of true. Good people don't even think about wickedness.
22. Metaethics / C. The Good / 1. Goodness / f. Good as pleasure
Music is good for a melancholic, bad for a mourner, and indifferent to the deaf [Spinoza]
     Full Idea: One and the same thing can, at the same time, be good and bad, and also indifferent. For example, music is good for one who is melancholy, bad for one who is mourning, and neither good nor bad to one who is deaf.
     From: Baruch de Spinoza (The Ethics [1675], IV Pref)
     A reaction: This sounds neat and obvious, but both the mourner and the deaf person might well acknowledge that music is a good thing, while failing to appreciate it at the time. I accept that a concert was good, even if I didn't attend it.
22. Metaethics / C. The Good / 2. Happiness / d. Routes to happiness
Man's highest happiness consists of perfecting his understanding, or reason [Spinoza]
     Full Idea: In life it is before all things useful to perfect the understanding, or reason, as far as we can, and in this alone man's highest happiness or blessedness consists.
     From: Baruch de Spinoza (The Ethics [1675], IVApp 04)
     A reaction: I fear that only a highly intelligent person like Spinoza would suggest this. The genius of Jesus is to say that if you don't have a powerful intellect you can still be happy by having a pure and loving heart. The Spinoza route is better, if possible.
22. Metaethics / C. The Good / 3. Pleasure / a. Nature of pleasure
Pleasure is a passive state in which the mind increases in perfection [Spinoza]
     Full Idea: By pleasure I shall signify a passive state wherein the mind passes to a greater perfection.
     From: Baruch de Spinoza (The Ethics [1675], III Pr 11)
     A reaction: A rather bizarre definition! He seems to be defining it as a state and as a process in the same sentence. It sounds to me like both a hedonist's charter, and nonsense. I'm with Plato and Aristotle, that pleasure is dangerous as it warps the mind.
22. Metaethics / C. The Good / 3. Pleasure / f. Dangers of pleasure
Pleasure is only bad in so far as it hinders a man's capability for action [Spinoza]
     Full Idea: Pleasure is only bad in so far as it hinders a man's capability for action.
     From: Baruch de Spinoza (The Ethics [1675], IV Pr 59)
     A reaction: This seems to be the incipient epicureanism found in enlightenment figures who are drifting towards atheism (of which his contemporaries accused Spinoza). Sadism? Grief is good pain. I'm too happy to be cruel.
23. Ethics / A. Egoism / 1. Ethical Egoism
Self-satisfaction is the highest thing for which we can hope [Spinoza]
     Full Idea: Self-satisfaction is the highest thing for which we can hope, for no one endeavours to preserve his being for the same of any end. [Pr 53: Humility is not a virtue]
     From: Baruch de Spinoza (The Ethics [1675], IV Pr 52)
     A reaction: You can sense here that Spinoza was not a family man.
No moral theory is of any use if it doesn't serve the interests of the individual concerned [Hume]
     Full Idea: What theory of morals can ever serve any useful purpose, unless it can show, by a particular detail, that all the duties which it recommends, are also the true interest of each individual?
     From: David Hume (Enquiry concerning Principles of Morals [1751], IX.II.228)
     A reaction: It is hard to disagree, even if occasional cases of extreme altruism can occur.
Reason demands nothing contrary to nature, and so it demands self-love [Spinoza]
     Full Idea: As reason makes no demands contrary to nature, it demands that every man should love himself, should seek that which is useful to him.
     From: Baruch de Spinoza (The Ethics [1675], IV Pr 18)
     A reaction: Maybe nature seems to demand self-love, but I don't see why reason should demand it, only why reason should not deny it. There is no point in denying something unavoidable. However, if we don't love ourselves, no one else is likely to.
23. Ethics / B. Contract Ethics / 1. Contractarianism
Both virtue and happiness are based on the preservation of one's own being [Spinoza]
     Full Idea: The foundation of virtue is the endeavour to preserve one's own being, and happiness consists in man's power of preserving his own being.
     From: Baruch de Spinoza (The Ethics [1675], IV Pr 18)
     A reaction: Spinoza never actually says so, but this seems to me to point to a Hobbesian social contract account of virtue - that is, that virtue is not an ideal, but a strategy. Personally I prefer the Aristotelian view, that it is an ideal revealed to us by nature.
23. Ethics / C. Virtue Theory / 1. Virtue Theory / a. Nature of virtue
Personal Merit is the possession of useful or agreeable mental qualities [Hume]
     Full Idea: Personal Merit consists altogether in the possession of mental qualities, useful or agreeable to the person himself or to others.
     From: David Hume (Enquiry concerning Principles of Morals [1751], IX.I.217)
     A reaction: If pleasure and utility can be intrinsically valuable, why can't virtue be as well?
23. Ethics / C. Virtue Theory / 1. Virtue Theory / b. Basis of virtue
All virtue is founded on self-preservation [Spinoza]
     Full Idea: The endeavour after self-preservation is the primary and only foundation of virtue.
     From: Baruch de Spinoza (The Ethics [1675], IV Pr 22)
     A reaction: This fits in perfectly with modern evolutionary ethics.
The more we strive for our own advantage, the more virtuous we are [Spinoza]
     Full Idea: The more each one strives, and is able, to seek his own advantage, that is, to preserve his being, the more he is endowed with virtue.
     From: Baruch de Spinoza (The Ethics [1675], IV Pr 20)
     A reaction: Beth Lord says this is his key ethical idea. Our conatus (striving) is the essence of our nature, and virtue is the perfect expression of our essence. Presumably the destruction of others in competition is also bad for us.
To act virtuously is to act rationally [Spinoza]
     Full Idea: To act in conformity to virtue is to act according to the guidance of reason.
     From: Baruch de Spinoza (The Ethics [1675], IV Pr 36)
     A reaction: This Kantian ideal always seems to be missing foundational values or feelings. If something is judged to be rubbish, I throw it away.
23. Ethics / C. Virtue Theory / 2. Elements of Virtue Theory / b. Living naturally
To live according to reason is to live according to the laws of human nature [Spinoza]
     Full Idea: Man acts absolutely according to the laws of his nature, when he lives in obedience to reason.
     From: Baruch de Spinoza (The Ethics [1675], IV Pr 35)
     A reaction: This is pure stoicism, and shows that Spinoza is in many ways the culmination of the seventeenth century stoic revival (e.g. in the art of Poussin). I love the idea that right reason and nature are in perfect harmony. I wonder why?
23. Ethics / C. Virtue Theory / 2. Elements of Virtue Theory / c. Motivation for virtue
All virtues benefit either the public, or the individual who possesses them [Hume]
     Full Idea: I desire you to consider if there be any quality that is virtuous, without having a tendency either to the public good or to the good of the person who possesses it.
     From: David Hume (Letters [1739], to Hutcheson 1739)
     A reaction: Obviously this is generally true. How, though, does it benefit the individual to secretly preserve their integrity? I go round to visit a friend to repay a debt; I am told they have died; I quietly leave some money on the table and leave. Why?
23. Ethics / C. Virtue Theory / 2. Elements of Virtue Theory / j. Unity of virtue
A man ignorant of himself is ignorant of all of the virtues [Spinoza]
     Full Idea: The man who is ignorant of himself is ignorant of the foundation of all the virtues, and consequently is ignorant of all the virtues.
     From: Baruch de Spinoza (The Ethics [1675], IV Pr 56)
     A reaction: This would appeal to Aristotle, for whom the social virtues are an aspect of one's own character, and not a calculation made about externals.
23. Ethics / C. Virtue Theory / 3. Virtues / c. Justice
If we all naturally had everything we could ever desire, the virtue of justice would be irrelevant [Hume]
     Full Idea: Suppose nature has bestowed on humans such abundance of external conveniences that every individual is fully provided with whatever his appetites can want. …Justice, in that case, would be totally useless, and have no place in the catalogue of virtues.
     From: David Hume (Enquiry concerning Principles of Morals [1751], I.III.145)
     A reaction: [compressed] This seems to emphasise possessions and satisfaction of appetites, but presumably it would also need total security from other humans, which nature might struggle to provide. No sharing in this imagined world.
Justice only exists to support society [Hume]
     Full Idea: The necessity of justice to the support of society is the sole foundation of that virtue.
     From: David Hume (Enquiry concerning Principles of Morals [1751], III.II.163)
     A reaction: A sense of fairness precedes the building of a society, rather than arising out of it.
23. Ethics / C. Virtue Theory / 3. Virtues / d. Courage
In a free man, choosing flight can show as much strength of mind as fighting [Spinoza]
     Full Idea: Flight at the proper time, just as well as fighting, is to be reckoned as showing strength of mind in a man who is free; that is to say, a free man chooses flight by the same strength or presence of mind as that by which he chooses battle.
     From: Baruch de Spinoza (The Ethics [1675], IV Pr 69)
     A reaction: I wonder why showing 'strength of mind' is a virtue?
23. Ethics / C. Virtue Theory / 3. Virtues / f. Compassion
People who live according to reason should avoid pity [Spinoza]
     Full Idea: A man who lives according to the dictates of reason endeavours as much as possible to prevent himself from being touched by pity.
     From: Baruch de Spinoza (The Ethics [1675], IV Pr 50)
     A reaction: Since pity seems to give rise to some thoroughly good actions, I am not quite clear how reason would give rise to those same actions unaided. The alleviation of another's pain seems to have no pure motivation, if there is no empathy.
A person unmoved by either reason or pity to help others is rightly called 'inhuman' [Spinoza]
     Full Idea: He who is moved neither by reason nor pity to be of any service to others is properly called inhuman; for he seems to be unlike a man.
     From: Baruch de Spinoza (The Ethics [1675], IV Pr 50)
     A reaction: Calling someone 'inhuman' doesn't seem like much of a condemnation. Nietzschean aristocrats may take pride in being above the mere 'human'. We gather here that if reason failed to motivate helping others, then pity would be a good thing.
Pity is a bad and useless thing, as it is a pain, and rational people perform good deeds without it [Spinoza]
     Full Idea: Pity is a pain, and is therefore in itself bad; only at the dictation of reason are we able to perform any action, which we know for certain to be good; thus, in a man who lives under the guidance of reason, pity in itself is useless and bad.
     From: Baruch de Spinoza (The Ethics [1675], IV Pr 50)
     A reaction: This is the essence of both Kant's and Bentham's views. It is, however, unclear why a wholly rational and unfeeling person should be motivated to prevent other people's pain. It also don't think it follows that because it is painful it is bad.
Pity is not a virtue, but at least it shows a desire to live uprightly [Spinoza]
     Full Idea: Pity, like shame, although it is not a virtue, is nevertheless good, in so far as it shows that a desire of living uprightly is present in the man who is possessed with shame.
     From: Baruch de Spinoza (The Ethics [1675], IV Pr 58)
     A reaction: And yet, in so far as I am rational, it seems that I should endeavour to suppress pity and replace it with right reason. Does Spinoza feel loyalty to the human race, I wonder?
23. Ethics / C. Virtue Theory / 4. External Goods / c. Wealth
Rational people judge money by needs, and live contented with very little [Spinoza]
     Full Idea: Those who know the true use of money, and regulate the measure of wealth according to their needs, live contented with few things.
     From: Baruch de Spinoza (The Ethics [1675], IVApp 29)
     A reaction: Spinoza himself lived up to this, being incredibly austere in his personal life.
23. Ethics / C. Virtue Theory / 4. External Goods / d. Friendship
Friendship without community spirit misses out on the main part of virtue [Hume]
     Full Idea: A man who is only susceptible of friendship, without public spirit or a regard to the community, is deficient in the most material part of virtue.
     From: David Hume (That Politics may be reduced to a Science [1750], p.21)
     A reaction: I think this is aimed at the epicureans. If the highest virtues are focused on one's friends that can easily lead to injustice, because it can tolerate prejudice against people who are very unlike one's friends.
23. Ethics / D. Deontological Ethics / 2. Duty
Moral philosophy aims to show us our duty [Hume]
     Full Idea: The end of all moral speculations is to teach us our duty.
     From: David Hume (Enquiry concerning Principles of Morals [1751], I.136)
     A reaction: A surprising view from someone who thinks morals are basically sentiment.
23. Ethics / D. Deontological Ethics / 3. Universalisability
Rational people are self-interested, but also desire the same goods for other people [Spinoza]
     Full Idea: Men who are governed by reason - that is, who seek what is useful to them in accordance with reason - desire for themselves nothing, which they do not also desire for the rest of mankind, and so are just, faithful and honourable in their conduct.
     From: Baruch de Spinoza (The Ethics [1675], IV Pr 18)
     A reaction: This is pulling a rather Kantian rabbit out of a very social contract hat. It chimes in with Aristotle's account of self-interest, which leads to good civic virtues. True Kantianism is self-abnegating, but Spinoza lets selfishness take the lead.
A rational person will want others to have the goods he seeks for himself [Spinoza]
     Full Idea: He who lives under the guidance of reason, desires for others the good which he seeks for himself.
     From: Baruch de Spinoza (The Ethics [1675], IV Pr 51)
     A reaction: Obviously a very Kantian idea. It implies that all rational people desire similar goods, but it is rational to collect stamps but not want other people to do so as well. I don't think you should want what I want for Christmas.
23. Ethics / D. Deontological Ethics / 6. Motivation for Duty
Conclusions of reason do not affect our emotions or decisions to act [Hume]
     Full Idea: Inference and conclusions of the understanding have no hold of the affections nor set in motion the active powers of man.
     From: David Hume (Enquiry concerning Principles of Morals [1751], I.136)
     A reaction: I disagree. This is a typical empiricist separation of ideas from experience, of inner from outer, of analytic from synthetic.
23. Ethics / E. Utilitarianism / 1. Utilitarianism
Virtue just requires careful calculation and a preference for the greater happiness [Hume]
     Full Idea: The sole trouble which virtue demands is that of just calculation, and a steady preference for the greater happiness.
     From: David Hume (Enquiry concerning Principles of Morals [1751], IX.II.228)
     A reaction: Hume was the parent of utilitarianism. Can one person exhibit virtue on a desert island?
23. Ethics / E. Utilitarianism / 3. Motivation for Altruism
No one would cause pain to a complete stranger who happened to be passing [Hume]
     Full Idea: Would any man, who is walking along, tread as willingly on another's gouty toes, whom he has no quarrel with, as on the hard flint and pavement?
     From: David Hume (Enquiry concerning Principles of Morals [1751], V.II.183)
     A reaction: He is right that we empathise with the pain of others, and this is presumably one of the bases of morality. Animals lack sympathy for other animals.
Nature makes private affections come first, because public concerns are spread too thinly [Hume]
     Full Idea: It is wisely ordained by nature, that private connexions should commonly prevail over universal views and considerations; otherwise our affections and actions would be dissipated and lost, for want of a proper limited object.
     From: David Hume (Enquiry concerning Principles of Morals [1751], V.II.186n)
     A reaction: A very good objection to the excessively altruistic demands of utilitarianism.
24. Political Theory / A. Basis of a State / 1. A People / a. Human distinctiveness
If people are obedient to reason, they will live in harmony [Spinoza]
     Full Idea: Men insofar as they live in obedience to reason, necessarily live always in harmony with one another.
     From: Baruch de Spinoza (The Ethics [1675], IV Pr 35)
     A reaction: A beautiful slogan for a belief which has gripped me since I was a child. It embodies the frustration of philosophers from Plato onwards, and it may well be childishly idealistic. Politics is the art of the possible, said R.A.B. Butler.
24. Political Theory / A. Basis of a State / 1. A People / c. A unified people
Peoples are created by individuals, not by nature, and only distinguished by language and law [Spinoza]
     Full Idea: Nature certainly does not create peoples, individuals do, and individuals are only separated into nations by differences of language, law and morality.
     From: Baruch de Spinoza (Tractatus Theologico-Politicus [1670], 17.26)
     A reaction: Quite wrong, I think. How did languages evolve if there were not already distinct peoples? Do ants and bees only form into colonies by individual choice? All social contract theories seem to make Spinoza's assumption.
The ideal for human preservation is unanimity among people [Spinoza]
     Full Idea: Man can wish for nothing more helpful to the preservation of his being than that all should so agree in all things that the minds and bodies of all would compose, as it were, one mind and one body.
     From: Baruch de Spinoza (The Ethics [1675], IV Pr 18S)
     A reaction: There has never been a more glorious vision of a unified people than this, which epitomises Enlightenment optimism. It may be a little on the optimistic side. We might at least hope that rational education encourages the convergence.
24. Political Theory / A. Basis of a State / 3. Natural Values / a. Natural freedom
Only self-knowledge can liberate us [Spinoza, by MacIntyre]
     Full Idea: In Spinoza, self-knowledge, and only self-knowledge, liberates.
     From: report of Baruch de Spinoza (The Ethics [1675]) by Alasdair MacIntyre - A Short History of Ethics Ch.10
     A reaction: Spinoza was a determinist, as far as ultimate inner freedom is concerned. The massive continental philosophers' effort of phenomenology and deconstruction seems to be premissed on this idea. Freedom seems to be their highest value.
24. Political Theory / A. Basis of a State / 3. Natural Values / b. Natural equality
People must have agreed to authority, because they are naturally equal, prior to education [Hume]
     Full Idea: When we consider how nearly equal all men are in their bodily force, and even in their mental powers and faculties, till cultivated by education, ...then nothing but their own consent could at first associate them together, and subject them to authority.
     From: David Hume (Of the original contract [1741], p.276)
     A reaction: This doesn't sound very convincing. Some people are much better suited than others to training and education. Men vary enormously in size.
24. Political Theory / A. Basis of a State / 3. Natural Values / c. Natural rights
In nature everything has an absolute right to do anything it is capable of doing [Spinoza]
     Full Idea: Since the universal power of nature is only the power of all individual things together, it follows that each individual thing has the sovereign right to do everything it can do, or the right of each thing extends as far as its determined power extends.
     From: Baruch de Spinoza (Tractatus Theologico-Politicus [1670], 16.01)
     A reaction: A typically ruthless Spinoza idea, very different from the rather ill-founded claims of Locke and Rousseau about the state of nature.
Natural rights are determined by desire and power, not by reason [Spinoza]
     Full Idea: Each person's natural right is determined not by sound reason but by desire and power. For it is not the case that all men are naturally determined to behave according to the rules and laws of reason
     From: Baruch de Spinoza (Tractatus Theologico-Politicus [1670], 16.03)
     A reaction: Locke would have been horrified by this. It looks like hopeless unfounded optimism to claim a natural right to anything. Doomed prey can struggle all it likes, but its right to do so seems irrelevant. Yet we see self-evident injustice all the time.
Spinoza extended Hobbes's natural rights to cover all possible desires and actions [Spinoza, by Tuck]
     Full Idea: It was Spinoza who extended the idea of natural rights to cover all possible desires and actions, and he did so knowing that he was transforming Hobbes's theory.
     From: report of Baruch de Spinoza (The Ethics [1675]) by Richard Tuck - Hobbes Ch.2
     A reaction: Hobbes had stuck to self-preservation. His problem was how to draw a line, saying that was a natural right, but there wasn't a natural right to a good bottle of claret. Spinoza's drastic solutions suggests that the whole approach is wrong.
24. Political Theory / B. Nature of a State / 1. Purpose of a State
The safety of the people is the supreme law [Hume]
     Full Idea: The safety of the people is the supreme law.
     From: David Hume (Enquiry concerning Principles of Morals [1751], III.II.157)
     A reaction: No political system ever seems able to disagree with this.
The only purpose of government is to administer justice, which brings security [Hume]
     Full Idea: Man is engaged to establish political society in order to administer justice, without which there could be no peace among them, nor safety, nor mutual intercourse. ...Government has no other purpose but the distribution of justice.
     From: David Hume (Of the Origin of Government [1750], p.28)
     A reaction: The need for a society in order to ensure mutual intercourse sounds like Hobbes, and a pessimism about trust. By 'justice' he means the administration of law.
The state aims to allow personal development, so its main purpose is freedom [Spinoza]
     Full Idea: It is the purpose of the state ...to allow people's minds and bodies to develop in their own way in security and enjoy the free use of reason ...Therefore the true purpose of the state is in fact freedom.
     From: Baruch de Spinoza (Tractatus Theologico-Politicus [1670], 20.06)
     A reaction: The core of Spinoza's political thinking. This strikes me as being as close to communitarianism as to liberalism.
Society exists to extend human awareness [Spinoza, by Watson]
     Full Idea: For Spinoza the purpose of society was the extension of human awareness.
     From: report of Baruch de Spinoza (Tractatus Theologico-Politicus [1670]) by Peter Watson - Ideas Ch.24
     A reaction: I like that. Personally I think human understanding is the best aim our lives can have, but I am inclined to see this in rather individualistic terms (despairing of getting others interested in the project!).
24. Political Theory / B. Nature of a State / 2. State Legitimacy / a. Sovereignty
Sovereignty must include the power to make people submit to it [Spinoza]
     Full Idea: Either there is no sovereignty nor any right over subjects, or else sovereignty must necessarily extend to everything that might be effective in inducing men to submit to it.
     From: Baruch de Spinoza (Tractatus Theologico-Politicus [1670], 17.02)
     A reaction: In the seventeenth century this usually includes the death penalty. Refusal to submit may be fairly passive and harmless, so the issue must concern duties, rather than rights. Taxes, jury duty, calls to arms.
24. Political Theory / B. Nature of a State / 2. State Legitimacy / c. Social contract
The idea that society rests on consent or promises undermines obedience [Hume]
     Full Idea: Were you to preach in most parts of the world that political connections are founded altogether on voluntary consent or a mutual promise, the magistrate would soon imprison you as seditious for loosening the ties of obedience.
     From: David Hume (Of the original contract [1741], p.278)
     A reaction: He cites obedience as the prime civic virtue, because the law can't operate without it. He doesn't seem to consider the limiting cases of obedience, which makes him essentially a conservative.
We no more give 'tacit assent' to the state than a passenger carried on board a ship while asleep [Hume]
     Full Idea: [If we give 'tacit' assent to the state] ...we may as well assert that a man, by remaining in a vessel, freely consents to the dominion of the master, though he was carried aboard while asleep.
     From: David Hume (Of the original contract [1741], p.283)
     A reaction: We should probably drop the whole idea that we give assent to the state. We are stuck with a state, and a few of us can escape, if it seems important enough, but most of us have no choice. He hope to assent to the controllers of the state.
The people would be amazed to learn that government arises from their consent [Hume]
     Full Idea: When we assert that all lawful government arises from the consent of the people, we certainly do them a great deal more honour than they deserve, or even expect or desire from us.
     From: David Hume (Of the original contract [1741], p.285)
     A reaction: Hume has no interest in the purely abstract idea of a contract, and scorns Locke's idea of tacit consent to government. I assume he would dismiss Rawls as unrealistic theorising. Hume loves peace, and is alarmed by change.
24. Political Theory / B. Nature of a State / 3. Constitutions
It would be absurd if even a free constitution did not impose restraints, for the public good [Hume]
     Full Idea: A republican and free form of government would be an obvious absurdity, if the particular checks and controls, provided by the constitution, had really no influence, and made it not the interest, even of bad men, to act for the public good.
     From: David Hume (That Politics may be reduced to a Science [1750], p.14)
     A reaction: Presumably if you attain absolute power you can write any old constitution you like (Clause 1: the presidency is for life). But there does seem much point in doing it - unless it is to facilitate the use of the law for persecutions.
24. Political Theory / C. Ruling a State / 2. Leaders / b. Monarchy
Kings tend to fight wars for glory, rather than for peace and liberty [Spinoza]
     Full Idea: As soon as the kings took control [of the Hebrews] the reason for going to war was no longer peace and liberty but rather glory,
     From: Baruch de Spinoza (Tractatus Theologico-Politicus [1670], 18.05)
     A reaction: As Spinoza was writing, Louis XIV had just invaded Holland, solely in quest of military glory. As soon as a leader like Napoleon discovers they are good at war, I assume that the thrill of glory takes over for them too.
Monarchs are always proud, and can't back down [Spinoza]
     Full Idea: Monarchical minds are always proud, and cannot back down without feelings of humiliation.
     From: Baruch de Spinoza (Tractatus Theologico-Politicus [1670], 18.05)
     A reaction: This would seem to be a problem in all politicians. As I teacher I found that backing down was sometimes quite a smart move, but you can only do it occasionally.
Deposing a monarch is dangerous, because the people are used to royal authority [Spinoza]
     Full Idea: It is dangerous to depose a monarch, even if it is clear by every criterion that he is a tyrant. A people accustomed to royal authority and held in check only by it, will despise any lesser authority and hold it in contempt.
     From: Baruch de Spinoza (Tractatus Theologico-Politicus [1670], 18.07)
     A reaction: He is obviously thinking of Charles I and Cromwell. I suspect that the respect for Cromwell in the 1650s was only as a great soldier. If the people miss royal authority, the correct response is probably 'get over it!'
Modern monarchies are (like republics) rule by law, rather than by men [Hume]
     Full Idea: In modern times monarchical government seems to have made the greatest advances towards perfection. It may now be affirmed of civilized monarchies, what was formerly said in praise of republics alone, that they are a government of laws, not of men.
     From: David Hume (Of Civil Liberty [1750], p.54)
     A reaction: Dreams of simple 'government by law' disappeared with the rise of modern media, which can be controlled by wealth.
24. Political Theory / C. Ruling a State / 2. Leaders / d. Elites
Nobility either share in the power of the whole, or they compose the power of the whole [Hume]
     Full Idea: A nobility may possess power in two different ways. Either every nobleman shares the power as part of the whole body, or the whole body enjoys the power as composed of parts, which each have a distinct power and authority.
     From: David Hume (That Politics may be reduced to a Science [1750], p.15)
     A reaction: He says the first type is found in Venice, and is preferable to the second type, which is found in Poland. Presumably in the shared version there is some restraint on depraved nobles. The danger is each noble being an autocrat.
24. Political Theory / C. Ruling a State / 3. Government / a. Government
Society prefers helpful lies to harmful truth [Hume]
     Full Idea: Truths which are pernicious to society, if any such there be, will yield to errors which are salutary and advantageous.
     From: David Hume (Enquiry concerning Principles of Morals [1751], IX.II.228)
     A reaction: Hume probably meant religion. Two centuries later we have a greater appetite for uncomfortable truth.
24. Political Theory / C. Ruling a State / 4. Changing the State / c. Revolution
Every state is more frightened of its own citizens than of external enemies [Spinoza]
     Full Idea: People have never succeeded in devising a form of government that was not in greater danger from its own citizens than from foreign foes, and which was not more fearful of the former than of the latter.
     From: Baruch de Spinoza (Tractatus Theologico-Politicus [1670], 17.04)
     A reaction: The sort of lovely clear-headed and accurate observation for which we love Spinoza. Only very powerful despots can afford to ignore the threat from the people. Stalin was paranoid, but eventually murdered almost everyone who seemed a threat.
24. Political Theory / D. Ideologies / 5. Democracy / c. Direct democracy
Democracy is a legitimate gathering of people who do whatever they can do [Spinoza]
     Full Idea: Democracy is properly defined as a united gathering of people which collectively has the sovereign right to do all that it has the power to do.
     From: Baruch de Spinoza (Tractatus Theologico-Politicus [1670], 16.08)
     A reaction: Representative democracy doesn't fit this definition. What 'unites' the people, and where do they get their sovereign right? If my neighbouring village votes to invade mine, I spurn their pathetic 'sovereign right'.
24. Political Theory / D. Ideologies / 10. Theocracy
Allowing religious ministers any control of the state is bad for both parties [Spinoza]
     Full Idea: How pernicious it is both for religion and the state to allow ministers of things sacred to acquire the right to make decrees or handle the business of government.
     From: Baruch de Spinoza (Tractatus Theologico-Politicus [1670], 18.06 (1))
     A reaction: Interesting that he holds it to be bad for the religion as well as the state. In Britain we have bishops in the House of Lords.
If religion is law, then piety is justice, impiety is crime, and non-believers must leave [Spinoza]
     Full Idea: [In the first Hebrew state] religious dogmas were not doctrines but rather laws and decrees, piety being regarded as justice and impiety as crime. Anyone who defected from this religion ceased to be a citizen.
     From: Baruch de Spinoza (Tractatus Theologico-Politicus [1670], 17.08)
     A reaction: Presumably speeding offences count as impiety, and failing to pray is a crime. A critical question will be how far religious doubts must extend before one actually has to leave. Mere doctrinal differences, or full atheism?
25. Social Practice / A. Freedoms / 1. Slavery
Slavery is a disgraceful crime [Spinoza]
     Full Idea: Slavery is a disgraceful crime.
     From: Baruch de Spinoza (The Ethics [1675], IVApp 21)
     A reaction: Note the date of this - when the slave trade is just getting going, and long before it is threatened or criticised.
Slavery is not just obedience, but acting only in the interests of the master [Spinoza]
     Full Idea: It is not acting on command in itself that makes someone a slave, but rather the reason for so acting. ...A slave is someone obliged to obey commands from a master which look only to the advantage of the master.
     From: Baruch de Spinoza (Tractatus Theologico-Politicus [1670], 16.10)
     A reaction: So if I forcibly enslaved you, and then only commanded things which were for your own good, that would not be slavery? If the master feeds the slave, is that not part of the slavery? Most jobs might count as slavery by this account?
25. Social Practice / A. Freedoms / 2. Freedom of belief
Government is oppressive if opinions can be crimes, because people can't give them up [Spinoza]
     Full Idea: Government is bound to become extremely oppressive where dissident opinions which are within the domain of each individual, a right which no one can give up, are treated as a crime.
     From: Baruch de Spinoza (Tractatus Theologico-Politicus [1670], 18.06 (2))
     A reaction: One might compare illicit desires, such as those of a paedophile, where it is a crime to act on them, but presumably they cannot be given up, so there is no point in legislating against the mere desires.
Without liberty of thought there is no trust in the state, and corruption follows [Spinoza]
     Full Idea: If liberty of thought is suppressed ...this would undemine the trust which is the first essential of a state; detestable flattery and deceit would flourish, giving rise to intrigues and every sort of honest behaviour.
     From: Baruch de Spinoza (Tractatus Theologico-Politicus [1670], 20.11)
     A reaction: Spinoza specifically defends philosophy, as the epitome of freedom of thought.
25. Social Practice / A. Freedoms / 3. Free speech
No government has ever suffered by being too tolerant of philosophy [Hume]
     Full Idea: A state ought to tolerate every principle of philosophy, nor is there any instance that a government has suffered in its political interests by such indulgence.
     From: David Hume (Enquiry Conc Human Understanding [1748], XI.114)
Treason may be committed as much by words as by deeds [Spinoza]
     Full Idea: We cannot altogether deny that treason may be committed as much by words as by deeds.
     From: Baruch de Spinoza (Tractatus Theologico-Politicus [1670], 20.05)
     A reaction: For example, betraying a major state secret. This is an important idea, for anyone who simplistically demands utter freedom of speech. There is also subversive speech, which is very hard to assess. Incitements can be crimes in Britain.
25. Social Practice / A. Freedoms / 6. Political freedom
The freest state is a rational one, where people can submit themselves to reason [Spinoza]
     Full Idea: The freest state is that whose laws are founded on sound reason; for there each man can be free whenever he wishes, that is, he can live under the guidance of reason with his whole mind.
     From: Baruch de Spinoza (Tractatus Theologico-Politicus [1670], 16.10)
     A reaction: I wonder if is not so much that the state is rational as that it is right. Freedom is submission to the truth. Rationality is only good because it arrives at truth. But is there a 'truth' about how a state should be run? Enlightenment optimism.
25. Social Practice / A. Freedoms / 7. Freedom to leave
Poor people lack the knowledge or wealth to move to a different state [Hume]
     Full Idea: Can we seriously say, that a poor peasant or artisan has a free choice to leave his country, when he knows no foreign language or manners, and lives, from day to day, by the small wages that he acquires?
     From: David Hume (Of the original contract [1741], p.283)
     A reaction: Of course, in the nineteenth century the Scottish poor did, going to America, which welcomed the poor, and spoke English. Hume's point is the right reply to anyone who says 'If you don't like it, go elsewhere'. Also 'No! Change it!'
25. Social Practice / B. Equalities / 4. Economic equality
If you equalise possessions, people's talents will make them unequal again [Hume]
     Full Idea: Render possessions ever so equal, men's different degrees of art, care, and industry will immediately break that equality.
     From: David Hume (Enquiry concerning Principles of Morals [1751], III.II.155)
     A reaction: This might not be so if there is a totalitarian restriction of economic freedom.
25. Social Practice / C. Rights / 1. Basis of Rights
Spinoza wanted democracy based on individual rights, and is thus the first modern political philosopher [Stewart,M on Spinoza]
     Full Idea: Spinoza's advocacy of democracy on the basis of individual rights was extraordinarily bold for its time, and it qualifies him as the first truly modern political philosopher.
     From: comment on Baruch de Spinoza (Tractatus Theologico-Politicus [1670]) by Matthew Stewart - The Courtier and the Heretic Ch. 6
     A reaction: Sounds right. Hobbes may have been the 'first modern man', but his politics was fairly medieval. John Lilburne and co. may have campaigned for rights and democracy, but they weren't really philosophers.
The sovereignty has absolute power over citizens [Spinoza]
     Full Idea: No offence can be committed against subjects by sovereigns, since they are of right permitted to do all things., and therefore offences occur only between private persons obliged by law not to harm one another.
     From: Baruch de Spinoza (Tractatus Theologico-Politicus [1670], 16.14)
     A reaction: This slightly alarming remark is the consequence of Spinoza's denial of natural rights. Nowadays we have international law to appeal to. Locke thinks revolution could be justified, but this implies the Spinoza does not?
There are two kinds of right - to power, and to property [Hume]
     Full Idea: Right is of two kinds: right to power and right to property.
     From: David Hume (Of the First Principles of Government [1750], p.25)
     A reaction: These seem to be positive rights. No mention of the right not be to unjustly abused. It is hard to find any sort of radical political thinking in Hume. His empirical scepticism extends to his politics. He approves of modern consitutional monarchy.
25. Social Practice / C. Rights / 3. Alienating rights
No one, in giving up their power and right, ceases to be a human being [Spinoza]
     Full Idea: No one will ever be able to transfer his power and (consequently) his right to another person in such a way that he ceases to be a human being.
     From: Baruch de Spinoza (Tractatus Theologico-Politicus [1670], 17.01)
     A reaction: Spinoza disdains natural rights, but this is a modest (and pretty uncontroversial) concession.
Forming a society meant following reason, and giving up dangerous appetites and mutual harm [Spinoza]
     Full Idea: People had to make a firm decision to decide everything by the sole dictates of reason (which no one dares contradict openly). They had to curb their appetites if it would hurt someone else, and not do to others what they did not want done to themselves.
     From: Baruch de Spinoza (Tractatus Theologico-Politicus [1670], 16.05)
     A reaction: The last bit invokes the Golden Rule. Being in society does indeed meaning curbing appetites, such as envy and lust.
People only give up their rights, and keep promises, if they hope for some greater good [Spinoza]
     Full Idea: No one will give up his right to all things, and absolutely no one will keep his promises, except from fear of a greater ill or hope of a greater good.
     From: Baruch de Spinoza (Tractatus Theologico-Politicus [1670], 16.06)
     A reaction: I think Locke and Rousseau would agree with this. It is hard to imagine doing anything other than in hope of a greater good. But what to do when your hopes are disappointed?
Once you have given up your rights, there is no going back [Spinoza]
     Full Idea: If people had wanted to keep any right for themselves, they should have made this provision at the same time as they could have safely defended it.
     From: Baruch de Spinoza (Tractatus Theologico-Politicus [1670], 16.08)
     A reaction: Spinoza is wonderful for grasping nettles. The other fans of social contracts seem blithely cheerful about how it is going to work out. But forming a society is like marriage - a risky commitment which could go horribly wrong.
In democracy we don't abandon our rights, but transfer them to the majority of us [Spinoza]
     Full Idea: In a democracy no one transfers their natural right to another in such a way that they are not thereafter consulted, but rather to the majority of the whole society of which they are part.
     From: Baruch de Spinoza (Tractatus Theologico-Politicus [1670], 16.11)
     A reaction: At this time democracy means Athenian direct democracy. In representative democracy you are only consulted once every few years, and in between the government can ignore the people (as Rousseau pointed out).
Everyone who gives up their rights must fear the recipients of them [Spinoza]
     Full Idea: People have never given up their right and transferred their power to another in such a way that they did not fear the very persons who received their right and power, and put the government at greater risk from its own citizens than from its enemies.
     From: Baruch de Spinoza (Tractatus Theologico-Politicus [1670], 17.01)
     A reaction: I take this idea to be Rousseau's key motivation for the idea of the general will, because you are there supposed to be alienating your natural rights to yourself (sort of). In a democracy you alienate them partly to yourself.
The early Hebrews, following Moses, gave up their rights to God alone [Spinoza]
     Full Idea: The Hebrews being in this natural state, they resolved, on the advice of Moses in whom they all had the greatest trust, to transfer their right to no mortal man but rather to God alone.
     From: Baruch de Spinoza (Tractatus Theologico-Politicus [1670], 17.07)
     A reaction: [He cites Exodus 24:7] He calls this the first Hebrew state, which seems to have depended heavily on Moses. Priests and prophets become crucial in this situation, and they may be in conflict about God's commands.
25. Social Practice / C. Rights / 4. Property rights
Hume thought (unlike Locke) that property is a merely conventional relationship [Hume, by Fogelin]
     Full Idea: Hume thought (in contrast to Locke) that property reflects a conventional (rather than natural) relationship determined by the laws that protect people from having things taken from them.
     From: report of David Hume (Nine political essays [1741]) by Robert Fogelin - Walking the Tightrope of Reason Ch.3
     A reaction: It seems pretty obvious that the idea of property was invented by the powerful, to protect their gains against the weak. I suspect that you might till a piece of land simply in order to assert ownership of it, just as you might bring in colonists.
We all know that the history of property is founded on injustices [Hume]
     Full Idea: Reason tells us that there is no property in durable objects, such as land or houses, when carefully examined in passing from hand to hand, but must, in some period, have been founded on fraud and injustice.
     From: David Hume (Of the original contract [1741], p.288)
     A reaction: A prime objection to Nozick, who fantasises about an initial position of just ownership, which can then be the subject of just contracts. In 1866 thousands of white people were granted land in the USA, but not a single black freed slave got anything.
It is an exaggeration to say that property is the foundation of all government [Hume]
     Full Idea: A noted author has made property the foundation of all government; and most of our political writers seem inclined to follow him in that particular. This is carrying the matter too far.
     From: David Hume (Of the First Principles of Government [1750], p.25)
     A reaction: This obviously refers to John Locke. Locke's idea strikes me as hideous. It says the foundation of government is the right of property owners to protect what they have against non-owners. It implies social exclusion in the constitution.
25. Social Practice / D. Justice / 2. The Law / c. Natural law
The order of nature does not prohibit anything, and allows whatever appetite produces [Spinoza]
     Full Idea: The order of nature, under which all human beings are born and for the most part live, prohibits nothing but what no one desires or no one can do; it does not prohibit strife or hatred or anger or anything at all that appetite foments.
     From: Baruch de Spinoza (Tractatus Theologico-Politicus [1670], 16.04)
     A reaction: This is as vigorous a rejection of natural law as I have met with. It is hard to see on what grounds anyone could disagree, other than hopeful sentiment.
25. Social Practice / E. Policies / 2. Religion in Society
State and religious law can clash, so the state must make decisions about religion [Spinoza]
     Full Idea: No one would be obliged by law if he considered it against his faith, and everyone could claim licence to do anything. Since the law of the state would then be wholly violated, it follows that the right of deciding about religion belongs to the sovereign.
     From: Baruch de Spinoza (Tractatus Theologico-Politicus [1670], 16.21)
     A reaction: This is an era when British puritans emigrate to America, because the state is not sufficiently tolerant. The needs of sovereignty and of religion can be very far apart. You can see those with great religious devotion not liking this idea.
25. Social Practice / E. Policies / 5. Education / c. Teaching
The best use of talent is to teach other people to live rationally [Spinoza]
     Full Idea: There is nothing by which a person can better show how much skill and talent he possesses than by so educating men that at last they will live under the direct authority of reason.
     From: Baruch de Spinoza (The Ethics [1675], IVApp 09)
     A reaction: Speaking as a retired philosophy teacher, I think this is an excellent idea, but then I would, wouldn't I? What if you turn a nice warm-hearted friendly young person into a chillingly detached heartless reasoner?
25. Social Practice / F. Life Issues / 4. Suicide
It is impossible that the necessity of a person's nature should produce a desire for non-existence [Spinoza]
     Full Idea: That a man, from the necessity of his own nature, should endeavour to become non-existent, is as impossible as that something should be made out of nothing.
     From: Baruch de Spinoza (The Ethics [1675], IV Pr 20)
     A reaction: At first glance this is very paradoxical, but it fits with evolutionary theory, which seems to make it almost inconceivable to naturally desire suicide. The desire to live is universal, and only circumstances can create an artifiical contradictory desire.
If suicide is wrong because only God disposes of our lives, it must also be wrong to save lives [Hume]
     Full Idea: Were the disposal of human life so much the peculiar province of the Almighty that it were an encroachment on His right, for men to dispose of their own lives; it would be equally criminal to act for the preservation of life as for its destruction.
     From: David Hume (On suicide [1775]), quoted by Jonathan Glover - Causing Death and Saving Lives §13
     A reaction: A characteristically wicked and neat point. Maybe we can intervene in the environment (diverting a falling stone), but not directly in a life? Life is sacred, but stones are not?
25. Social Practice / F. Life Issues / 6. Animal Rights
Animals feel, but that doesn't mean we can't use them for our pleasure and profit [Spinoza]
     Full Idea: I by no means deny that brutes feel, but I do deny that on this account it is unlawful for us to consult our own profit by using them for our own pleasure and treating them as is most convenient for us, inasmuch as they do not agree in nature with us.
     From: Baruch de Spinoza (The Ethics [1675], IV Pr 37)
     A reaction: Something a bit chilling about this. What if I decided that some people did 'not agree with my nature'? Presumably pleasure includes hunting? What was his attitude to bear-baiting?
26. Natural Theory / A. Speculations on Nature / 1. Nature
We can easily think of nature as one individual [Spinoza]
     Full Idea: We may easily conceive the whole of nature to be one individual.
     From: Baruch de Spinoza (The Ethics [1675], II Lem 7)
26. Natural Theory / A. Speculations on Nature / 2. Natural Purpose / b. Limited purposes
Nature has no particular goal in view, and final causes are mere human figments [Spinoza]
     Full Idea: Nature has no particular goal in view, and final causes are mere human figments.
     From: Baruch de Spinoza (The Ethics [1675], IApp)
     A reaction: This is Spinoza's famous rejection of Aristotelian teleology, which was the last seventeenth century nail in the coffin of the great man. Spinoza substitutes God, but loss of faith in that concept then left us with no purpose at all, as in Hume.
We can discover some laws of nature, but never its ultimate principles and causes [Hume]
     Full Idea: The ultimate springs and principles are totally shut up from human enquiry. Elasticity, gravity, cohesion of parts, communication of motion by impulse; these are probably the ultimate causes and principles which we shall ever discover in nature.
     From: David Hume (Enquiry Conc Human Understanding [1748], IV.I.26)
26. Natural Theory / A. Speculations on Nature / 2. Natural Purpose / c. Purpose denied
Spinoza strongly attacked teleology, which is the lifeblood of classical logos [Roochnik on Spinoza]
     Full Idea: In his 'Ethics' Spinoza shows his enormous hostility to teleology, which is the lifeblood of classical logos.
     From: comment on Baruch de Spinoza (The Ethics [1675]) by David Roochnik - The Tragedy of Reason p.77
For Spinoza eyes don't act for purposes, but follow mechanical necessity [Roochnik on Spinoza]
     Full Idea: Aristotle would be perfectly happy with the idea that the eyes are for the purpose of seeing. Spinoza would disagree. The objects of the world, including parts of living organisms, have purposes, but obey the laws of mechanical necessity.
     From: comment on Baruch de Spinoza (The Ethics [1675]) by David Roochnik - The Tragedy of Reason p.79
     A reaction: My view is that eyes wouldn't exist if they didn't see, which places them in a different category from inorganic matter.
Final causes are figments of human imagination [Spinoza]
     Full Idea: All final causes are nothing but human fictions.
     From: Baruch de Spinoza (The Ethics [1675], IApp)
     A reaction: You can see why Spinoza was rather controversial in the late seventeenth century, when he says things as bold as this, even though he is echoing Descartes. The latter's proposal (Idea 12730) is methodological, whereas this idea is metaphysical.
26. Natural Theory / A. Speculations on Nature / 5. Infinite in Nature
An infinite line can be marked in feet or inches, so one infinity is twelve times the other [Spinoza]
     Full Idea: If an infinite line be measured out in feet, it will consist of an infinite number of such parts; it would equally consist of an infinite number of parts, if each part was only an inch; therefore, one infinity would be twelve times as great as the other.
     From: Baruch de Spinoza (The Ethics [1675], I Pr 15)
     A reaction: This seems to anticipate Cantor. Spinoza's point seemed bewildering then, but is now accepted as a standard feature of the concept of infinity.
26. Natural Theory / A. Speculations on Nature / 6. Early Matter Theories / c. Ultimate substances
In nature there is just one infinite substance [Spinoza]
     Full Idea: In nature only one substance exists, and it is absolutely infinite.
     From: Baruch de Spinoza (The Ethics [1675], I Pr 10)
     A reaction: This seems to render the concept of 'substance' redundant, since all the interest is now in the attributes (or whatever) of this one substance, and we must work to discount the appearance of there being numerous substances (e.g. you and me).
26. Natural Theory / A. Speculations on Nature / 7. Later Matter Theories / a. Early Modern matter
We have no good concept of solidity or matter, because accounts of them are all circular [Hume]
     Full Idea: In order to form an idea of solidity, we must conceive two bodies pressing on each other without penetration. ..The ideas of secondary qualities are excluded, and the idea of motion depends on extension. This leaves us no just idea of solidity or matter.
     From: David Hume (Treatise of Human Nature [1739], I.IV.4), quoted by Stephen Mumford - Dispositions 02.3
     A reaction: [compressed] For me these kind of strict empiricist arguments always recede when you accept the notion of an inference to be best explanation. We have some sort of notion of 'matter', but here the physicist seems to take over.
26. Natural Theory / C. Causation / 1. Causation
If a singular effect is studied, its cause can only be inferred from the types of events involved [Hume]
     Full Idea: Only when two species of objects are constantly conjoined can we infer one from the other; were an entirely singular effect presented, which could not be comprehended under a species, I do not see that we could form any conjecture concerning its cause.
     From: David Hume (Enquiry Conc Human Understanding [1748], XI.115)
     A reaction: A key issue in causation. Note that Hume is willing to discuss causation in a freakishly unique happening, but only if he can spot a 'type' in the each of the events. I don't like it, but the man has a good point…
A priori it looks as if a cause could have absolutely any effect [Hume]
     Full Idea: If we just reason a priori, anything may appear able to produce anything. The falling of a pebble may, for aught we know, extinguish the sun.
     From: David Hume (Enquiry Conc Human Understanding [1748], XII.III.132)
26. Natural Theory / C. Causation / 3. Final causes
A final cause is simply a human desire [Spinoza]
     Full Idea: A cause which is called final is nothing else but human desire, in so far as it is considered as the origin or cause of anything.
     From: Baruch de Spinoza (The Ethics [1675], IV Pref)
     A reaction: A rather vicious swipe at Aristotle! It chimes in with the modern scientific view of the world (mostly associated with Hume), that nature has no intrinsic values or aims. On the large scale, Spinoza is right, but nature can still show us what has value.
The idea of a final cause is very uncertain and unphilosophical [Hume]
     Full Idea: Your sense of 'natural' is founded on final causes, which is a consideration that appears to me pretty uncertain and unphilosophical.
     From: David Hume (Letters [1739], to Hutcheson 1739)
     A reaction: This is the rejection of Aristotelian teleology by modern science. I agree that the notion of utterly ultimate final cause is worse than 'uncertain' - it is an impossible concept. Nevertheless, I prefer Aristotle to Hume. Nature can teach us lessons.
26. Natural Theory / C. Causation / 7. Eliminating causation
Hume never even suggests that there is no such thing as causation [Hume, by Strawson,G]
     Full Idea: At no point (in Sect VII of 'Enquiries') does Hume even hint at the thesis that there is (or even might be) no such thing as causation.
     From: report of David Hume (Enquiry Conc Human Understanding [1748], VII) by Galen Strawson - The Secret Connexion 21.3
     A reaction: If, as some people think, Hume is a phenomenalist, then we wouldn't expect him to actually deny the existence of such things. The standard position (cf. Ayer on religion) is that such things are not even worth mentioning.
26. Natural Theory / C. Causation / 8. Particular Causation / b. Causal relata
At first Hume said qualities are the causal entities, but later he said events [Hume, by Davidson]
     Full Idea: In the Enquiries Hume clearly suggests that causes and effects are entities that can be named or described by singular terms; probably events, since one can follow another; but in the Treatise it seems to be the quality or circumstance which is the cause.
     From: report of David Hume (Enquiry Conc Human Understanding [1748]) by Donald Davidson - Causal Relations §1
     A reaction: A quality would have to have an associated power if it was going to trigger an effect. But then so would an event (unless inertia carried across?). Qualities are more distinct. Events can last for years.
26. Natural Theory / C. Causation / 8. Particular Causation / c. Conditions of causation
For Hume a constant conjunction is both necessary and sufficient for causation [Hume, by Crane]
     Full Idea: Hume held that constant conjunction between As and Bs is both necessary and sufficient for a causal relation. If As and Bs are conjoined that is sufficient for a causal relation; if A and B are causally related, necessarily they are constantly conjoined.
     From: report of David Hume (Treatise of Human Nature [1739]) by Tim Crane - Causation 1.2.2
     A reaction: A helpful connection between Hume and the modern debate about conditions for causation (e.g. Mackie). It sounds as if, to spot the necessary condition, you need to independently see that A and B are causally related, which regularity does not allow.
26. Natural Theory / C. Causation / 9. General Causation / a. Constant conjunction
Causation is just invariance, as long as it is described in general terms [Quine on Hume]
     Full Idea: Hume explained cause as invariable succession, and this makes sense as long as the cause and effect are referred to by general terms. … This account leaves singular causal statements unexplained.
     From: comment on David Hume (Treatise of Human Nature, + Appendix [1740]) by Willard Quine - Natural Kinds p.131
     A reaction: A nice 20th century linguistic point made against a good 18th century theory.
Hume says we can only know constant conjunctions, not that that's what causation IS [Hume, by Strawson,G]
     Full Idea: Hume's regularity theory of causation is only a theory about causation so far as we can know about it or contentfully conceive of it in the objects, not about causation as it is in the objects.
     From: report of David Hume (Enquiry Conc Human Understanding [1748], IV.I) by Galen Strawson - The Secret Connexion App C
If impressions, memories and ideas only differ in vivacity, nothing says it is memory, or repetition [Whitehead on Hume]
     Full Idea: Hume confuses 'repetition of impressions' with 'impression of repetitions of impressions'. ...In order of 'force and vivacity' we have: impressions, memories, ideas. This omits the vital fact that memory is memory; the notion of repetition is lost.
     From: comment on David Hume (Treatise of Human Nature, + Appendix [1740]) by Alfred North Whitehead - Process and Reality V.II
     A reaction: [compressed; Harré and Madden spotted this idea] This seems to pinpoint rather nicely the hopeless thinness of Hume's account. He is so desperate to get it down to minimal empirical experience that his explanations are too thin. One big idea....
No causes can be known a priori, but only from experience of constant conjunctions [Hume]
     Full Idea: Without exception, knowledge of cause and effect is not attained by reasonings a priori, but arises entirely from experience, when we find that any particular objects are constantly conjoined with each other.
     From: David Hume (Enquiry Conc Human Understanding [1748], IV.I.23)
In both of Hume's definitions, causation is extrinsic to the sequence of events [Psillos on Hume]
     Full Idea: What needs to be stressed is that in both of Hume's definitions of cause, an individual sequence of events is deemed causal only because something extrinsic to the sequence occurs (be it conjunctions, or a mental link).
     From: comment on David Hume (Enquiry Conc Human Understanding [1748], VII.II.60) by Stathis Psillos - Causation and Explanation §1.9
     A reaction: Simple but important. Hume's basic claim is that there is no 'causation' in events, apart from the events themselves. Hence no necessity, on top of the apparent contingency.
Hume's definition of cause as constantly joined thoughts can't cover undiscovered laws [Ayer on Hume]
     Full Idea: Hume's second definition of cause (one object always 'conveys the thought' of another) implies that it is inconceivable that there should be causal laws which have never yet been thought of, and this is not so.
     From: comment on David Hume (Enquiry Conc Human Understanding [1748], VII.II.60) by A.J. Ayer - Language,Truth and Logic Ch.2
     A reaction: This appears to be a good criticism of Hume, but also a bit of a problem for a strong empiricist like Ayer. There may also be causal laws which we cannot discover, but logical positivism will not allow me to speculate about that.
A cause is either similar events following one another, or an experience always suggesting a second experience [Hume]
     Full Idea: A cause is an object, followed by another, and where all the objects similar to the first are followed by objects similar to the second, or, an object followed by another, and whose appearance always conveys the thought to that other.
     From: David Hume (Enquiry Conc Human Understanding [1748], VII.II.60)
It is only when two species of thing are constantly conjoined that we can infer one from the other [Hume]
     Full Idea: It is only when two species of object are found to be constantly conjoined, that we can infer the one from the other.
     From: David Hume (Enquiry Conc Human Understanding [1748], XI.115)
     A reaction: what is a species?
26. Natural Theory / C. Causation / 9. General Causation / c. Counterfactual causation
Cause is where if the first object had not been, the second had not existed [Hume]
     Full Idea: We may define a cause to be where .....if the first object had not been, the second never had existed.
     From: David Hume (Enquiry Conc Human Understanding [1748], 7.2.60)
     A reaction: This is Hume's second definition, cited by Lewis as the ancestor of his counterfactual theory. It feels all wrong to me. 'If there had been no window, there would have been no window-breakage'?
26. Natural Theory / C. Causation / 9. General Causation / d. Causal necessity
From a definite cause an effect necessarily follows [Spinoza]
     Full Idea: From a definite cause an effect necessarily follows.
     From: Baruch de Spinoza (The Ethics [1675], I Ax 3)
     A reaction: This encapsulate the view against which Hume was rebelling. However, nowadays no one thinks Spinoza is self-evidently wrong. How are we to distinguish between a cause and a coincident event? We must claim natural necessity.
Hume seems to presuppose necessary connections between mental events [Kripke on Hume]
     Full Idea: A well-known objection to Hume's analysis of causation is that he presupposes necessary connections between mental events in the theory.
     From: comment on David Hume (Treatise of Human Nature [1739]) by Saul A. Kripke - Wittgenstein on Rules and Private Language n 87
     A reaction: Are these the associations that occur within the mind? I'm not clear about the objection, but record it for interest.
That events could be uncaused is absurd; I only say intuition and demonstration don't show this [Hume]
     Full Idea: I never asserted so absurd a proposition as that anything might arise without a cause: I only maintained that our certainty of the falsehood of that proposition proceeded neither from intuition nor from demonstration, but from another source.
     From: David Hume (Letters [1739], 1754), quoted by Brian Davies - Introduction to the Philosophy of Religion 5 'God'
     A reaction: Since the other source is habit, he is being a bit disingenuous. While rational intuition and demonstration give a fairly secure basis for the universality of causation, mere human habits of expectation give very feeble grounds.
Hume never shows how a strong habit could generate the concept of necessity [Harré/Madden on Hume]
     Full Idea: Hume's contemporary critics are correct. He never really shows how it is possible for a habit, however strong it may be, to generate the concept of necessity.
     From: comment on David Hume (Enquiry Conc Human Understanding [1748]) by Harré,R./Madden,E.H. - Causal Powers 3.II
     A reaction: This is a powerful objection which hadn't occurred to me. Presumably eighteenth century critics are referred to? I suppose if a necessity is what 'cannot be otherwise', a very deeply ingrained habit might seem that way - but in me, not in the world.
Hume's regularity theory of causation is epistemological; he believed in some sort of natural necessity [Hume, by Strawson,G]
     Full Idea: Hume's Regularity theory of causation is about causation as we know about it or contentfully conceive of it in the objects. As far as causation as it is in the objects is concerned, Hume firmly believed in some sort of natural necessity or causal power.
     From: report of David Hume (Enquiry Conc Human Understanding [1748]) by Galen Strawson - The Secret Connexion App C
     A reaction: Strawson's controversial reinterpretation of Hume. We are confusing his epistemology with his ontology. Hume is simply being sceptical about our ability to bridge the gap to achieve understanding of natural necessity. A very different view of Hume.
In observing causes we can never observe any necessary connections or binding qualities [Hume]
     Full Idea: When we look towards external objects, and consider the operation of causes, we are never able to discover any power or necessary connexion, any quality which binds the effect to the cause.
     From: David Hume (Enquiry Conc Human Understanding [1748], VII.I.50)
28. God / A. Divine Nature / 1. God
The key question for Spinoza is: is his God really a God? [Stewart,M on Spinoza]
     Full Idea: The single most important question that can be raised about Spinoza's philosophy is: Is his God really a God?
     From: comment on Baruch de Spinoza (The Ethics [1675]) by Matthew Stewart - The Courtier and the Heretic Ch.13
     A reaction: Novalis called Spinoza a "God-intoxicated man", but this question shows why many of Spinoza's contemporaries (and later) considered him to be an atheist. The general modern answer by commentators to the question appears to be 'No!'.
28. God / A. Divine Nature / 2. Divine Nature
God is the sum and principle of all eternal laws [Spinoza, by Armstrong,K]
     Full Idea: For Spinoza God is simply the principle of law, the sum of all the eternal laws in existence.
     From: report of Baruch de Spinoza (The Ethics [1675]) by Karen Armstrong - A History of God Ch.9
     A reaction: This seems at variance with the usual view, that Spinoza identifies God with the single substance which makes up nature, and that he is hence a pantheist. Compare the above idea with Idea 4829, for example. Spinoza's God seems close to Aristotle's.
God is a substance with infinite attributes [Spinoza]
     Full Idea: By God, I understand Being absolutely infinite, that is to say, substance consisting of infinite attributes, each one of which expresses eternal and infinite essence.
     From: Baruch de Spinoza (The Ethics [1675], I Def 6)
God feels no emotions, of joy or sorrow [Spinoza]
     Full Idea: God is free from passions, neither is He affected with any affect of joy or sorrow.
     From: Baruch de Spinoza (The Ethics [1675], V Pr 17)
     A reaction: The general Christian view is that God has great compassion for human suffering, as Jesus appears to have had. Spinoza was very very intellectual.
Spinoza's God is not a person [Spinoza, by Jolley]
     Full Idea: Spinoza's God is not a person.
     From: report of Baruch de Spinoza (The Ethics [1675]) by Nicholas Jolley - Leibniz Ch.5
     A reaction: This will be the central reason why Spinoza was so controversial, because such a view instantly makes religion pointless, despite retaining a core of theism.
Spinoza's God is just power and necessity, without perfection or wisdom [Leibniz on Spinoza]
     Full Idea: The Spinozist view allows God infinite power only, not granting him either perfection or wisdom, and dismisses searches for final causes and explains everything through brute necessity.
     From: comment on Baruch de Spinoza (The Ethics [1675]) by Gottfried Leibniz - New Essays on Human Understanding 73
     A reaction: It takes a genius like Leibniz to explain so clearly what Spinoza was up to. Some call Spinoza 'God-intoxicated', but others say he is an incipient atheist. The latter is probably closer to the truth.
God does not act according to the freedom of the will [Spinoza]
     Full Idea: God does not act according to the freedom of the will.
     From: Baruch de Spinoza (The Ethics [1675], I Pr 32)
     A reaction: Personally I am struck by the idea that even if God had 'free will', I can't see how He would be sure of the fact (the unperceived puppetmaster!). However, I have actually come to the conclusion that a fotally 'free' will is an incoherent concept.
God is not loveable for producing without choice and by necessity; God is loveable for his goodness [Leibniz on Spinoza]
     Full Idea: There is nothing loveable in a God who produces without choice and by necessity, without discrimination of good and evil. The true love of God is founded not in necessity but in goodness.
     From: comment on Baruch de Spinoza (The Ethics [1675], IV Pr 28) by Gottfried Leibniz - Comments on Spinoza's Philosophy
     A reaction: This responds to Spinoza's claims about an 'intellectual' love of God. But why do we love people. It is possible that it is always for their goodness, but might we not love a great mathematician, simply for their wonderful mathematics?
God is wholly without passions, and strictly speaking does not love anyone [Spinoza, by Cottingham]
     Full Idea: God, asserts Spinoza, is wholly without passions, and strictly speaking does not love anyone.
     From: report of Baruch de Spinoza (The Ethics [1675]) by John Cottingham - The Rationalists p.179
     A reaction: This seems to me a much more plausible conception of God than the anthropomorphic one of him as the perfect parent who dotes on his offspring.
God has no purpose, because God lacks nothing [Spinoza]
     Full Idea: If God works to obtain an end, He necessarily seeks something of which he stands in need.
     From: Baruch de Spinoza (The Ethics [1675], IApp)
     A reaction: The point is that a being with infinite attributes cannot be in need of anything, and hence God merely exists, but does not have a purpose. Hence falling in line with God's purposes cannot be an aim of a human religion.
28. God / A. Divine Nature / 3. Divine Perfections
God is a being with infinite attributes, each of them infinite or perfect [Spinoza]
     Full Idea: I define God as a being consisting in infinite attributes, whereof each is infinite or supremely perfect.
     From: Baruch de Spinoza (Letters to Oldenburg [1665], 1661)
     A reaction: This seems to me the glorious culmination of the hyperbolic conception of God that expands steadily from wood spirits through Zeus, to eventually mop up everything in nature, and then everything that can be imagined beyond nature. All very silly.
God no more has human perfections than we have animal perfections [Spinoza]
     Full Idea: To ascribe to God those attributes which make a man perfect would be as wrong as to ascribe to a man the attributes that make perfect an elephant or an ass.
     From: Baruch de Spinoza (Letters to Blijenburgh [1665], 1665), quoted by Matthew Stewart - The Courtier and the Heretic Ch.10
     A reaction: This would be a difficulty for Aquinas's Fourth Way (Idea 1432), and one which I think Aquinas might acknowledge, given his desire that we should be humble when trying to comprehend God (Idea 1410). It leaves us struggling to grasp the concept of God.
We can't assume God's perfections are like our ideas or like human attributes [Hume]
     Full Idea: But let us beware, lest we think, that our ideas anywise correspond to his perfections, or that his attributes have any resemblance to these qualities among men.
     From: David Hume (Dialogues Concerning Natural Religion [1751], Part 2)
28. God / A. Divine Nature / 6. Divine Morality / c. God is the good
To say that God promotes what is good is false, as it sets up a goal beyond God [Spinoza]
     Full Idea: Those who maintain that God acts in all things with a view of promoting what is good are very far from the truth. For they seem to set up something beyond God, which does not depend on God, but which God looks to as an exemplar or goal.
     From: Baruch de Spinoza (The Ethics [1675], I Pr 33)
     A reaction: That is, Spinoza agrees with Euthyphro, and disagrees with Socrates (see Idea 337). Personally I agree with Socrates, but then I am not 'intoxicated with God' as Spinoza was. If God isn't good, why worship Him?
28. God / B. Proving God / 1. Proof of God
The objects of theological reasoning are too big for our minds [Hume]
     Full Idea: But in theological reasonings … we are employed upon objects, which, we must be sensible, are too large for our grasp.
     From: David Hume (Dialogues Concerning Natural Religion [1751], Part 1)
28. God / B. Proving God / 2. Proofs of Reason / a. Ontological Proof
Spinoza says a substance of infinite attributes cannot fail to exist [Spinoza, by Lord]
     Full Idea: Spinoza does not argue from the concept of God to his existence; he argues that a substance of infinite attributes cannot not exist.
     From: report of Baruch de Spinoza (The Ethics [1675], I Def 6) by Beth Lord - Spinoza's Ethics 1 P11
     A reaction: Lord is explicit that this is NOT the argument used by Anselm and Descartes. I'm not clear why there has to be a substance of infinite attributes, but presumably that is explained somewhere.
Denial of God is denial that his essence involves existence, which is absurd [Spinoza]
     Full Idea: God, or substance consisting of infinite attributes, each one of which expresses eternal and infinite essence, necessarily exists. If this be denied, conceive that God does not exist. But then his essence does not involve existence, which is absurd.
     From: Baruch de Spinoza (The Ethics [1675], I Pr 11)
     A reaction: Not a very powerful version of the ontological argument. Gaunilo offered an island which has existence as part of its essence, which would pass the same test.
God is being as such, and you cannot conceive of the non-existence of being [Spinoza, by Lord]
     Full Idea: Spinoza argues that you cannot conceive the non-existence of God because you cannot conceive the non-existence of being. God, or a substance of infinite attributes, is being as such.
     From: report of Baruch de Spinoza (The Ethics [1675], I Pr 11) by Beth Lord - Spinoza's Ethics I P11
     A reaction: I'm not clear why I cannot conceive of nothing whatever existing. I can conceive of my fridge being empty, so conceiving non-being is not off limits. Not that inconceivability is an infallible guide to impossibility…
God must necessarily exist, because no reason can be given for his non-existence [Spinoza]
     Full Idea: A thing necessarily exists if no cause or reason be granted which prevents its existence. No cause can be given which prevents the existence of God, or which destroys his existence, so we must conclude that he necessarily exists.
     From: Baruch de Spinoza (The Ethics [1675], I Pr 11)
     A reaction: I can't think of any reason why there shouldn't be a giant rat which fills a large proportion of the universe. Indeed, it may be the missing 'dark matter'. So presumably it has necessary existence. Proving non-existence is obviously tricky.
Some things makes me conceive of it as a thing whose essence requires its existence [Spinoza]
     Full Idea: By cause of itself, I understand that, whose essence involves existence; or that, whose nature cannot be conceived unless existing.
     From: Baruch de Spinoza (The Ethics [1675], I Def 1)
     A reaction: Obviously he has God in mind, but might this apply to abstract existence. Can I conceive of the number seven, while also conceiving that there is no such number? Compare Pegasus.
28. God / B. Proving God / 2. Proofs of Reason / b. Ontological Proof critique
If a thing can be conceived as non-existing, its essence does not involve existence [Spinoza]
     Full Idea: If a thing can be conceived as non-existing, its essence does not involve existence.
     From: Baruch de Spinoza (The Ethics [1675], I Ax 7)
     A reaction: This points straight at the modern question of whether conceivability is a sufficient test for possibility. Personally I am close to Hume on this one. Necessary existence may not be ridiculous, but it is beyond human capacity to assert its occurrence.
It can never be a logical contradiction to assert the non-existence of something thought to exist [Hume]
     Full Idea: Whatever 'is' may 'not be'. No negation of a fact can involve a contradiction. The non-existence of any being, without exception, is as clear and distinct an idea as its existence.
     From: David Hume (Enquiry Conc Human Understanding [1748], XII.III.132)
No being's non-existence can imply a contradiction, so its existence cannot be proved a priori [Hume]
     Full Idea: Nothing that is distinctly conceivable implies a contradiction. Whatever we conceive of as existent we can also conceive as non-existent. So there is no being whose non-existence implies a contradiction. So no being's existence is demonstrable.
     From: David Hume (Dialogues Concerning Natural Religion [1751], Part 9)
     A reaction: I totally subscribe to this idea, and take claims that nature actually contains contradictions (based on the inevitable quantum mechanics) to be ridiculous. Nature is the embodiment, chief exemplar and prime test of consistency.
28. God / B. Proving God / 3. Proofs of Evidence / a. Cosmological Proof
A chain of events requires a cause for the whole as well as the parts, yet the chain is just a sum of parts [Hume]
     Full Idea: The whole chain or succession [of causes and effects], taken together, is not caused by anything, and yet it is evident that it requires a cause or reason, as much as any particular object which begins to exist in time.
     From: David Hume (Dialogues Concerning Natural Religion [1751], Part 9)
     A reaction: This is such a major and significant idea. With blinkers on we think our questions are answered. Then someone (a philosopher, inevitably) makes you pull back and ask a much wider and more difficult question.
If something must be necessary so that something exists rather than nothing, why can't the universe be necessary? [Hume]
     Full Idea: What was it that determined something to exist rather than nothing? ...This implies a necessary being… But why may not the material universe be the necessarily existent being?
     From: David Hume (Dialogues Concerning Natural Religion [1751], Part 9)
     A reaction: There certainly seems no need for whatever the necessary thing is that it qualify as a 'god'. If could be a necessary subatomic particle that suddenly triggers reactions.
28. God / B. Proving God / 3. Proofs of Evidence / b. Teleological Proof
The thing which contains order must be God, so see God where you see order [Hume]
     Full Idea: By supposing something to contain the principle of its order within itself, we really assert it to be God; and the sooner we arrive at that divine being, so much the better.
     From: David Hume (Dialogues Concerning Natural Religion [1751], Part 4)
28. God / B. Proving God / 3. Proofs of Evidence / c. Teleological Proof critique
You can't infer the cause to be any greater than its effect [Hume]
     Full Idea: If we infer a cause from an effect, we must proportion the one to the other. …a body of ten ounces raised in a scale proves the counterbalance exceeds ten ounces, but not that it exceeds a hundred.
     From: David Hume (Enquiry Conc Human Understanding [1748], XI.105)
Analogy suggests that God has a very great human mind [Hume]
     Full Idea: Since the effects resemble, we must infer by analogy that the causes also resemble; and that the Author of Nature is somewhat similar to the mind of man, though possessed of much larger faculties, proportioned to the grandeur of his work.
     From: David Hume (Dialogues Concerning Natural Religion [1751], Part 2)
From our limited view, we cannot tell if the universe is faulty [Hume]
     Full Idea: It is impossible for us to tell, from our limited views, whether this system contains any great faults.
     From: David Hume (Dialogues Concerning Natural Religion [1751], Part 5)
Creation is more like vegetation than human art, so it won't come from reason [Hume]
     Full Idea: If the universe is more like animal bodies and vegetables than works of human art, it is more probable that its cause resembles the cause of the former than of the latter, and its cause should be ascribed to generation rather than to reason of design.
     From: David Hume (Dialogues Concerning Natural Religion [1751], Part 7)
Order may come from an irrational source as well as a rational one [Hume]
     Full Idea: Why an orderly system may not be spun from the belly as well as from the brain, it will be difficult … to give a satisfactory reason.
     From: David Hume (Dialogues Concerning Natural Religion [1751], Part 7)
Why would we infer an infinite creator from a finite creation? [Hume]
     Full Idea: By this method of reasoning, you renounce all claim to infinity in any of the attributes of the deity. For … the cause ought only to be proportioned to the effect, and the effect, so far as it falls under our cognizance, is not infinite.
     From: David Hume (Dialogues Concerning Natural Religion [1751], Part 5)
If the divine cause is proportional to its effects, the effects are finite, so the Deity cannot be infinite [Hume]
     Full Idea: By this method of reasoning you renounce all claim to infinity in any of the attributes of the Deity. The cause ought to be proportional to the effect, and the effect, so far as it falls under our cognizance, is not infinite.
     From: David Hume (Dialogues Concerning Natural Religion [1751], Part 5)
     A reaction: You cannot deny that the Deity MAY be infinite, be only accept that your evidence is not enough to prove it. But if nothing infinite has been observed, it is a reasonable provisional inference that nothing infinite exists.
From a ship you would judge its creator a genius, not a mere humble workman [Hume]
     Full Idea: It is uncertain whether all the excellences of the work can justly be ascribed to the workman. If we survey a ship, what an exalted idea must we form of the ingenuity of the carpenter ...and what surprise must we feel when we find him a stupid mechanic.
     From: David Hume (Dialogues Concerning Natural Religion [1751], Part 5)
     A reaction: You can at least infer that the ship was not made entirely by makers who are ignorant of carpentry. Somewhere in the divine team there must exist the skills that produce whatever we observe?
Design cannot prove a unified Deity. Many men make a city, so why not many gods for a world? [Hume]
     Full Idea: How can you prove the unity of a Deity? A great number of men join in building a house or ship, in rearing a city; why may not several deities combine in contriving and framing a world?
     From: David Hume (Dialogues Concerning Natural Religion [1751], Part 5)
     A reaction: You might look at the Cistine Chapel ceiling and conclude that only a team could have achieve such a thing. Since there is no way to infer how many gods might be involved, then one god is a possible theory.
This excellent world may be the result of a huge sequence of trial-and-error [Hume]
     Full Idea: Many worlds might have been botched and bungled, throughout an eternity, ere this system was struck out; many fruitless trials made, and a slow but continued improvement carried on during infinite ages in the art of world-making.
     From: David Hume (Dialogues Concerning Natural Religion [1751], Part 5)
     A reaction: Lee Smolin, a modern cosmographer, suggests that this evolution may have led to the current universe, after a long train of selective creations. The idea of natural selection was waiting to happen in 1760.
Humans renew their species sexually. If there are many gods, would they not do the same? [Hume]
     Full Idea: Men are mortal and renew their species by generation. Why must this circumstance, so universal, so essential, be excluded from those numerous and limited deities?
     From: David Hume (Dialogues Concerning Natural Religion [1751], Part 5)
     A reaction: Hume observes that this would be like the Greek gods. Hume makes mincemeat of attempts to prove the existence of God merely by analogy with human affairs.
This Creator god might be an infant or incompetent or senile [Hume]
     Full Idea: [Maybe] this world ...was only the first essay of some infant deity ...or it is the work only of some dependent, inferior deity, the object of derision to his superiors ...or it is the product of the dotage of some superannuated deity...
     From: David Hume (Dialogues Concerning Natural Religion [1751], Part 5)
     A reaction: His opponent in the dialogue rejoices that, in the face of these sacreligious fantasies, Hume still accepts the likelihood of some sort of design. Hume is right that it is not much of a theory if nothing can be said about the Designer.
Motion often begins in matter, with no sign of a controlling agent [Hume]
     Full Idea: Motion in many instances begins in matter, without any known voluntary agent; to suppose always, in these cases, an unknown voluntary agent is mere hypothesis, attended with no advantages.
     From: David Hume (Dialogues Concerning Natural Religion [1751], Part 8)
     A reaction: This is the modern 'powers' view of science, and a direct contradiction of Plato's claims in The Laws. It seems a bit primitive to assume that magnetism must be the work of some god.
The universe could settle into superficial order, without a designer [Hume]
     Full Idea: The universe goes on in a succession of chaos and disorder. But is it not possible that it may settle at last, so as not to lose its inherent motion and active force, yet so as to produce a uniformity of appearance, amidst the continual fluctuation.
     From: David Hume (Dialogues Concerning Natural Religion [1751], Part 8)
     A reaction: From what I know of the constant fluctuation of virtual particles (e.g. inside protons) this is exactly what actually is happening. There is an 'appearance' of order, but at the lowest level this is not the case.
Ideas arise from objects, not vice versa; ideas only influence matter if they are linked [Hume]
     Full Idea: In all known instances, ideas are copied from real objects. You reverse this order and give thought the precedence. ...Thought has no influence upon matter except where that matter is so conjoined with it as to have an equal reciprocal influence upon it.
     From: David Hume (Dialogues Concerning Natural Religion [1751], Part 8)
     A reaction: He allows something like mental causation, provided mind and brain are closely linked. Hume brings out the close relationship between divine design theories, and the mind-body problem.
A surprise feature of all products of 9 looks like design, but is actually a necessity [Hume]
     Full Idea: The products of 9 always compose either 9 or some lesser product of 9, if you add the characters of the product. To a superficial observer this regularity appears as chance or design, but a skilful algebraist sees it as necessity.
     From: David Hume (Dialogues Concerning Natural Religion [1751], Part 9)
     A reaction: An example of this universal generality is that 369 is a product of 9 (9x41), and if you add 3, 6 and 9 you get 18, which is 2x9. Similar examples occur in nature, such as crystals, which are necessary once the atomic structure is known.
The universe may be the result of trial-and-error [Hume]
     Full Idea: Many worlds might have been botched and bungled, throughout an eternity, ere this system was struck out.
     From: David Hume (Dialogues Concerning Natural Religion [1751], Part 5)
How can we pronounce on a whole after a brief look at a very small part? [Hume]
     Full Idea: A very small part of this great system, during a very short time, is very imperfectly discovered to us: and do we thence pronounce decisively concerning the origin of the whole?
     From: David Hume (Dialogues Concerning Natural Religion [1751], Part 2)
28. God / B. Proving God / 3. Proofs of Evidence / e. Miracles
A miracle violates laws which have been established by continuous unchanging experience, so should be ignored [Hume]
     Full Idea: A miracle is a violation of the laws of nature, and as a firm and unalterable experience has established these laws, the proof against a miracle is as entire as any argument from experience can possible be imagined.
     From: David Hume (Enquiry Conc Human Understanding [1748], X.I.90)
Trying to prove God's existence through miracles is proving the obscure by the more obscure [Spinoza]
     Full Idea: Those who endeavour to establish God's existence and the truth of religion by means of miracles seek to prove the obscure by what is more obscure.
     From: Baruch de Spinoza (Letters to Oldenburg [1665], 1675?)
     A reaction: Nicely put. On the whole this has to be right, but one must leave open a possibility. If there is a God, and He seeks to prove Himself by a deed, are we saying this is impossible? Divine intervention might be the best explanation of something.
Priests reject as heretics anyone who tries to understand miracles in a natural way [Spinoza]
     Full Idea: Anyone who seeks the true cause of miracles, and strives to understand natural phenomena as an intelligent being, and not to gaze at them like a fool, is denounced as an impious heretic by those whom the masses adore as interpreters of nature and gods.
     From: Baruch de Spinoza (The Ethics [1675], IApp)
     A reaction: A rather bitter personal remark, by someone who was driven out of Amsterdam as a heretic. Presumably the heresy is not aggressive a priori naturalism, but mere openness to the possibility of natural explanations of miracles.
It can't be more rational to believe in natural laws than miracles if the laws are not rational [Ishaq on Hume]
     Full Idea: In Hume's argument against miracles, how can it be more rational to believe the laws than the miracles, if the laws themselves are not based on reason?
     From: comment on David Hume (Of Miracles [1748]) by Atif Ishaq - talk
     A reaction: A very nice question. Hume never presents his argument with such an overt reliance on reason. But if the argument says you are in the 'habit' of expecting no anomalies in the laws, what is to prevent you changing the habit of a lifetime?
All experience must be against a supposed miracle, or it wouldn't be called 'a miracle' [Hume]
     Full Idea: There must be a uniform experience against every miraculous event, otherwise the event would not merit that appellation.
     From: David Hume (Enquiry Conc Human Understanding [1748], X.I.90)
To establish a miracle the falseness of the evidence must be a greater miracle than the claimed miraculous event [Hume]
     Full Idea: No testimony is sufficient to establish a miracle, unless the testimony be of such a kind that its falsehood would be more miraculous than the fact which it endeavours to establish.
     From: David Hume (Enquiry Conc Human Understanding [1748], X.I.91)
28. God / C. Attitudes to God / 2. Pantheism
Everything is in God, and nothing exists or is thinkable without God [Spinoza]
     Full Idea: Whatever is, is in God, and nothing can either be or be conceived without God.
     From: Baruch de Spinoza (The Ethics [1675], I Pr 15)
     A reaction: Presumably atheists are not very good at conceiving, because they don't understand properly. This is the pantheism for which Spinoza became famous, or notorious. Critics said he was a closet atheist.
God is the efficient cause of essences, as well as of existences [Spinoza]
     Full Idea: God is not only the efficient cause of the existence of things, but also of their essence.
     From: Baruch de Spinoza (The Ethics [1675], I Pr 25)
     A reaction: This is close to Leibniz's view that the so-called 'laws of nature' are not imposed by God from outside, but are rooted with nature, in the essences of what has been created (which is modern scientific essentialism).
That God is the substance of all things is an ill-reputed doctrine [Leibniz on Spinoza]
     Full Idea: That God is the very nature or substance of all things is the sort of doctrine of ill repute which a recent writer, subtle indeed, though profane, either introduced to the world or revived.
     From: comment on Baruch de Spinoza (The Ethics [1675], I) by Gottfried Leibniz - On Nature Itself (De Ipsa Natura) §08
     A reaction: This is clearly a comment on Spinoza. Leibniz seems to have spent his whole life in shock after his meeting with Spinoza.
The human mind is part of the infinite intellect of God [Spinoza]
     Full Idea: The human mind is part of the infinite intellect of God.
     From: Baruch de Spinoza (The Ethics [1675], II Pr 11)
     A reaction: What is the difference between being a part of something which totally fails to communicate with the whole, and being separate from the whole? Spinoza's proposal strikes me as daft.
28. God / C. Attitudes to God / 4. God Reflects Humanity
The idea of an infinite, intelligent, wise and good God arises from augmenting the best qualities of our own minds [Hume]
     Full Idea: The idea of God, as meaning an infinitely intelligent, wise and good being, arises from reflecting on the operations of our own mind, and augmenting, without limit, those qualities of goodness and wisdom.
     From: David Hume (Enquiry Conc Human Understanding [1748], II.14)
A talking triangle would say God is triangular [Spinoza]
     Full Idea: If a triangle could speak it would say that God is eminently triangular.
     From: Baruch de Spinoza (Letters to Blijenburgh [1665], 1665), quoted by Matthew Stewart - The Courtier and the Heretic Ch.10
     A reaction: Spinoza had a rather appealing waspish wit. This nicely dramatises an ancient idea (Idea 407). You can, of course, if you believe in God, infer some of His characteristics from His creation. But then see Hume: Ideas 1439, 6960, 6967, 1440.
28. God / C. Attitudes to God / 5. Atheism
In Spinoza, one could substitute 'nature' or 'substance' for the word 'God' throughout [Spinoza, by Stewart,M]
     Full Idea: In Spinoza's 'Ethics' one can substitute the word "Nature" (or "Substance", or even simply an X) for God throughout, and the logic of the argument changes little, if at all.
     From: report of Baruch de Spinoza (The Ethics [1675]) by Matthew Stewart - The Courtier and the Heretic Ch.13
     A reaction: This claim, if correct, is the clearest statement of why we should really consider Spinoza one of the first atheists, despite his endless use of the word 'God'.
29. Religion / B. Monotheistic Religion / 2. Judaism
Hebrews were very hostile to other states, who had not given up their rights to God [Spinoza]
     Full Idea: Having transferred their right to God, the Hebrews believed their kingdom was the kingdom of God, that they alone were the children of God, and that other nations were enemies of God, whom for that reason they regarded with extreme hostility.
     From: Baruch de Spinoza (Tractatus Theologico-Politicus [1670], 17.23)
     A reaction: [He cites Psalm 139:21-2] So, according to Spinoza, they did not become the chosen people because they thought God had chosen then, but because they were the only state trying to align itself with God.
29. Religion / B. Monotheistic Religion / 5. Bible
The Bible has nothing in common with reasoning and philosophy [Spinoza]
     Full Idea: The Bible leaves reason absolutely free and has nothing in common with philosophy.
     From: Baruch de Spinoza (Tractatus Theologico-Politicus [1670])
     A reaction: Hm. The Bible may not contain reasoning, but it contains the fruits of reasoning, and it is obviously possible for reasoning to contradict its message.
29. Religion / D. Religious Issues / 2. Immortality / a. Immortality
After death, something eternal remains of the mind [Spinoza]
     Full Idea: The human mind cannot be absolutely destroyed with the body, but something of it remains which is eternal.
     From: Baruch de Spinoza (The Ethics [1675], V Pr 23)
     A reaction: This sounds contrary to Spinoza's monism of mind and body, but he seems to mean little more than that minds are reabsorbed into the whole. See Beth Lord's commentary [p.146]. Compare stoics on the subject.
Spinoza's theory of mind implies that there is no immortality [Spinoza, by Stewart,M]
     Full Idea: A final (and for his contemporaries, dreadful) consequence of Spinoza's theory of the mind is that there is no personal immortality.
     From: report of Baruch de Spinoza (The Ethics [1675]) by Matthew Stewart - The Courtier and the Heretic Ch.10
     A reaction: For Spinoza's view of the mind, see Idea 4308. The denial of immortality would also seem to be a consequence of modern emergentist views of the mind, which is espoused by religious people looking for a compromise between dualism and science.
If all of my perceptions were removed by death, nothing more is needed for total annihilation [Hume]
     Full Idea: Were all my perceptions removed by death, and I could I neither think nor feel nor see nor love nor hate, after the dissolution of my body, I should be enitrely annihilated, nor do I conceive what is further requisite to make me a perfect non-entity.
     From: David Hume (Treatise of Human Nature [1739], I.IV.6)
     A reaction: 'A perfect non-entity'. How about that for an eighteenth century rejection of immortality of the soul? In the context, his point is that the has no enduring self, apart from this range of experiences.
