79 ideas

1. Philosophy / A. Wisdom / 1. Nature of Wisdom
Wisdom is the science of happiness [Leibniz]
     Full Idea: Wisdom is the science of happiness.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1690.03.23)
     A reaction: That probably comes down to common sense, or Aristotle's 'phronesis'. I take wisdom to involve understanding, as well as the quest for happiness.
1. Philosophy / A. Wisdom / 2. Wise People
Wise people have fewer acts of will, because such acts are linked together [Leibniz]
     Full Idea: The wiser one is, the fewer separate acts of will one has and the more one's views and acts of will are comprehensive and linked together.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.04.12)
     A reaction: [letter to Landgrave, about Arnauld] It is unusual to find a philosopher who actually tries to analyse the nature of wisdom, instead of just paying lipservice to it. I take Leibniz to be entirely right here. He equates wisdom with rational behaviour.
1. Philosophy / D. Nature of Philosophy / 1. Philosophy
Great philosophies are confessions by the author, growing out of moral intentions [Nietzsche]
     Full Idea: It has gradually become clear to me what every great philosophy has hitherto been: a confession on the part of its author, and a kind of involuntary and unconscious memoir, ...with moral intentions being the real germ of its life.
     From: Friedrich Nietzsche (Beyond Good and Evil [1886], §006)
     A reaction: This attitude is what places Nietzsche as the parent of post-modernism, and is the reason why most 'continental' philosophers seem to have given up the attempt to simply reason about life. It is anti-Enlightenment, and it is wicked.
1. Philosophy / E. Nature of Metaphysics / 2. Possibility of Metaphysics
Metaphysics divided the old unified Greek world into two [Nietzsche, by Critchley]
     Full Idea: Nietzsche famously defines metaphysics as the division of one world into two; the unity of the mythical pre-philosophical experience of the world is sundered, with Plato, into being and seeming, reality and appearance, supersensible and sensible.
     From: report of Friedrich Nietzsche (Beyond Good and Evil [1886]) by Simon Critchley - Continental Philosophy - V. Short Intro
     A reaction: (Critchley doesn't give a reference; Idea 2860 is close). This is the discredited status that metaphysics gradually acquired after Kant, but I see modern metaphysics as reuniting human thought by digging down to the foundations to reveal roots and links.
1. Philosophy / E. Nature of Metaphysics / 5. Metaphysics beyond Science
Metaphysics is geometrical, resting on non-contradiction and sufficient reason [Leibniz]
     Full Idea: I claim to give metaphysics geometric demonstrations, assuming only the principle of contradiction (or else all reasoning becomes futile), and that nothing exists without a reason, or that every truth has an a priori proof, from the concept of terms.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.07.4/14 XI)
     A reaction: For the last bit, see Idea 12910. This idea is the kind of huge optimism about metaphysic which got it a bad name after Kant, and in modern times. I'm optimistic about metaphysics, but certainly not about 'geometrical demonstrations' of it.
2. Reason / D. Definition / 4. Real Definition
Definitions can only be real if the item is possible [Leibniz]
     Full Idea: Definitions to my mind are real, when one knows that the thing defined is possible; otherwise they are only nominal, and one must not rely on them.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.07.4/14 XI)
     A reaction: It is interesting that things do not have to actual to have real definitions. For Leibniz, what is possible will exist in the mind of God. For me what is possible will exist in the potentialities of the powers of what is actual.
3. Truth / A. Truth Problems / 1. Truth
The predicate is in the subject of a true proposition [Leibniz]
     Full Idea: In a true proposition the concept of the predicate is always present in the subject.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.07.4/14 X)
     A reaction: This sounds very like the Kantian notion of an analytic truth, but Leibniz is applying it to all truths. So Socrates must contain the predicate of running as part of his nature (or essence?), if 'Socrates runs' is to be true.
A truth is just a proposition in which the predicate is contained within the subject [Leibniz]
     Full Idea: In every true affirmative proposition, necessary or contingent, universal or particular, the concept of the predicate is in a sense included in that of the subject; the predicate is present in the subject; or else I do not know what truth is.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.07.4/14)
     A reaction: Why did he qualify this with "in a sense"? This is referred to as the 'concept containment theory of truth'. This is an odd view of the subject. If the truth is 'Peter fell down stairs', we don't usually think the concept of Peter contains such things.
3. Truth / A. Truth Problems / 3. Value of Truth
Why do we want truth, rather than falsehood or ignorance? The value of truth is a problem [Nietzsche]
     Full Idea: What really is it in us that wants 'the truth'? ...Granted we want truth: why not rather untruth? And uncertainty? Even ignorance? The problem of the value of truth stepped before us.
     From: Friedrich Nietzsche (Beyond Good and Evil [1886], §001)
     A reaction: I think this is one of the great moments in philosophy, when something that has been taken for granted, as a kind of mantra, is suddenly looked in the face and challenged. Truth at all costs? What sacrifices would you make for truth?
6. Mathematics / A. Nature of Mathematics / 4. Using Numbers / a. Units
There is no multiplicity without true units [Leibniz]
     Full Idea: There is no multiplicity without true units.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1687.04.30)
     A reaction: Hence real numbers do not embody 'multiplicity'. So either they don't 'embody' anything, or they embody 'magnitudes'. Does this give two entirely different notions, of measure of multiplicity and measures of magnitude?
7. Existence / A. Nature of Existence / 3. Being / c. Becoming
Nietzsche resists nihilism through new values, for a world of becoming, without worship [Nietzsche, by Critchley]
     Full Idea: Nietzsche's work is a resistance to nihilism. This is why he insists that new categories and values are required that would permit us to endure this world of becoming without either falling into despair or inventing some new god and bowing before it.
     From: report of Friedrich Nietzsche (Beyond Good and Evil [1886]) by Simon Critchley - Continental Philosophy - V. Short Intro
     A reaction: The trouble is that all Nietzsche offers is the invention of values out of nothing by some wretched Germanic übermensch who is obsessed with militarism and dominance. If values don't grow out of human nature, then 'all is permitted'.
7. Existence / A. Nature of Existence / 3. Being / g. Particular being
What is not truly one being is not truly a being either [Leibniz]
     Full Idea: What is not truly one being is not truly a being either.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1687.04.30), quoted by Alain Badiou - Briefings on Existence 1
     A reaction: Badiou quotes this as identifying Being with the One. I say Leibniz had no concept of 'gunk', and thought everything must have a 'this' identity in order to exist, which is just the sort of thing a logician would come up with.
7. Existence / C. Structure of Existence / 5. Supervenience / a. Nature of supervenience
A thing 'expresses' another if they have a constant and fixed relationship [Leibniz]
     Full Idea: One thing 'expresses' another (in my terminology) when there exists a constant and fixed relationship between what can be said of one and of the other. This is the way that a perspectival projection expresses its ground-plan.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1687.10.09)
     A reaction: Arnauld was puzzled by what Leibniz might mean by 'express', and it occurs to me that Leibniz was fishing for the modern concept of 'supervenience'. It also sounds a bit like the idea of 'covariance' between mind and world. Maybe he means 'function'.
8. Modes of Existence / C. Powers and Dispositions / 2. Powers as Basic
A substance contains the laws of its operations, and its actions come from its own depth [Leibniz]
     Full Idea: Each indivisible substance contains in its nature the law by which the series of its operations continues, and all that has happened and will happen to it. All its actions come from its own depths, except for dependence on God.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1688.01.4/14)
     A reaction: I take the combination of 'laws' and 'forces', which Leibniz attributes to Aristotelian essences, to be his distinctive contribution towards giving us an Aristotelian metaphysic which is suitable for modern science.
9. Objects / B. Unity of Objects / 1. Unifying an Object / a. Intrinsic unification
Philosophy needs the precision of the unity given by substances [Leibniz]
     Full Idea: Philosophy cannot be better reduced to something precise, than by recognising only substances or complete beings endowed with a true unity, with different states that succeed one another; all else is phenomena, abstractions or relations.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1687.04.30), quoted by Daniel Garber - Leibniz:Body,Substance,Monad 7
     A reaction: This idea bothers me. Has the whole of modern philosophy been distorted by this yearning for 'precision'? It has put mathematicians and logicians in the driving seat. Do we only attribute unity because it suits our thinking?
9. Objects / B. Unity of Objects / 1. Unifying an Object / b. Unifying aggregates
Accidental unity has degrees, from a mob to a society to a machine or organism [Leibniz]
     Full Idea: There are degrees of accidental unity, and an ordered society has more unity than a chaotic mob, and an organic body or a machine has more unity than a society.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1687.04.30)
     A reaction: This immediately invites questions about the extremes. Why does the very highest degree of 'accidental unity' not achieve 'true unity'? And why cannot a very ununified aggregate have a bit of unity (as in unrestricted mereological composition)?
9. Objects / B. Unity of Objects / 1. Unifying an Object / c. Unity as conceptual
We find unity in reason, and unity in perception, but these are not true unity [Leibniz]
     Full Idea: A pair of diamonds is merely an entity of reason, and even if one of them is brought close to another, it is an entity of imagination or perception, that is to say a phenomenon; contiguity, common movement and the same end don't make substantial unity.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1687.04.30), quoted by Daniel Garber - Leibniz:Body,Substance,Monad 7
     A reaction: This invites the question of what you have to do to two objects to give them substantial unity. The distinction between unity 'of reason' and unity 'of perception' is good.
9. Objects / B. Unity of Objects / 2. Substance / a. Substance
A body is a unified aggregate, unless it has an indivisible substance [Leibniz]
     Full Idea: One will never find a body of which it may be said that it is truly one substance, ...because entities made up by aggregation have only as much reality as exists in the constituent parts. Hence the substance of a body must be indivisible.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.11)
     A reaction: Leibniz rejected atomism, and he evidently believed that pure materialists must deny the real existence of physical objects. Common sense suggests that causal bonds bestow a high degree of unity on bodies (if degrees are allowed).
Unity needs an indestructible substance, to contain everything which will happen to it [Leibniz]
     Full Idea: Substantial unity requires a complete, indivisible and naturally indestructible entity, since its concept embraces everything that is to happen to it, which cannot be found in shape or motion.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.11.28/12.8)
     A reaction: Hence if a tile is due to be broken in half (Arnauld's example), it cannot have had unity in the first place. To what do we refer when we say 'the tile was broken'?
Every bodily substance must have a soul, or something analogous to a soul [Leibniz]
     Full Idea: Every bodily substance must have a soul, or at least an entelechy which is analogous to the soul.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1687.10.09)
     A reaction: He routinely commits to a 'soul', and then pulls back and says it may only be an 'analogy'. He had deep doubts about his whole scheme, which emerged in the late correspondence with Des Bosses. This not monads, says Garber.
9. Objects / B. Unity of Objects / 2. Substance / b. Need for substance
Aggregates don’t reduce to points, or atoms, or illusion, so must reduce to substance [Leibniz]
     Full Idea: In aggregates one must necessarily arrive either at mathematical points from which some make up extension, or at atoms (which I dismiss), or else no reality can be found in bodies, or finally one must recognises substances that possess a true unity.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1687.04.30), quoted by Daniel Garber - Leibniz:Body,Substance,Monad 2
     A reaction: Garber calls this Leibniz's Aggregate Argument. Leibniz is, of course, talking of physical aggregates which have unity. He consistently points out that a pile of logs has no unity at all. But is substance just that-which-provides-unity?
9. Objects / B. Unity of Objects / 2. Substance / d. Substance defined
Substance needs independence, unity, and stability (for individuation); also it is a subject, for predicates [Perkins]
     Full Idea: For individuation, substance needs three properties: independence, to separate it from other things; unity, to call it one thing, rather than an aggregate; and permanence or stability over time. Its other role is as subject for predicates.
     From: Franklin Perkins (Leibniz: Guide for the Perplexed [2007], 3.1)
     A reaction: Perkins is describing the Aristotelian view, which is taken up by Leibniz. 'Substance' is not a controversial idea, if we see that it only means that the world is full of 'things'. It is an unusual philosopher wholly totally denies that.
9. Objects / D. Essence of Objects / 1. Essences of Objects
Basic predicates give the complete concept, which then predicts all of the actions [Leibniz]
     Full Idea: Apart from those that depend on others, one must only consider together all the basic predicates in order to form the complete concept of Adam adequate to deduce from it everything that is ever to happen to him, as much as is necessary to account for it.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.06)
     A reaction: This (implausibly) goes beyond mere prediction of properties. Eve's essence seems to be relevant to Adam's life. Note that the complete concept is not every predicate, but only those 'necessary' to predict the events. Cf Idea 13082.
Essences exist in the divine understanding [Leibniz]
     Full Idea: Essences exist in the divine understanding before one considers will.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.07.4/14 X)
     A reaction: This is a sort of religious neo-platonism. The great dream seems to be that of mind-reading God, and the result is either Pythagoras (it's numbers!), or Plato (it's pure ideas!), or this (it's essences!). See D.H.Lawrence's poem on geranium and mignottes.
9. Objects / D. Essence of Objects / 6. Essence as Unifier
Bodies need a soul (or something like it) to avoid being mere phenomena [Leibniz]
     Full Idea: Every substance is indivisible and consequently every corporeal substance must have a soul or at least an entelechy which is analogous to the soul, since otherwise bodies would be no more than phenomena.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], G II 121), quoted by Daniel Garber - Leibniz:Body,Substance,Monad 2
     A reaction: There is a large gap between having 'a soul' and having something 'analogous to a soul'. I take the analogy to be merely as originators of action. Leibniz wants to add appetite and sensation to the Aristotelian forms (but knows this is dubious!).
9. Objects / D. Essence of Objects / 10. Essence as Species
Truths about species are eternal or necessary, but individual truths concern what exists [Leibniz]
     Full Idea: The concept of a species contains only eternal or necessary truths, whereas the concept of an individual contains, regarded as possible, what in fact exists or what is related to the existence of things and to time.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.06)
     A reaction: This seems to be what is behind the preference some have for kind-essences rather than individual essences. But the individual must be explained, as well as the kind. Not all tigers are identical. The two are, of course, compatible.
10. Modality / E. Possible worlds / 3. Transworld Objects / a. Transworld identity
If varieties of myself can be conceived of as distinct from me, then they are not me [Leibniz]
     Full Idea: I can as little conceive of different varieties of myself as of a circle whose diameters are not all of equal length. These variations would all be distinct one from another, and thus one of these varieties of myself would necessarily not be me.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.05.13)
     A reaction: This seems to be, at the very least, a rejection of any idea that I could have a 'counterpart'. It is unclear, though, where he would place a version of himself who learned a new language, or who might have had, but didn't have, a haircut.
If someone's life went differently, then that would be another individual [Leibniz]
     Full Idea: If the life of some person, or something went differently than it does, nothing would stop us from saying that it would be another person, or another possible universe which God had chosen. So truly it would be another individual.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.07.14)
     A reaction: Plantinga quotes this as an example of 'worldbound individuals'. This sort of remark leads to people saying that Leibniz believes all properties are essential, since they assume that his notion of essence is bound up with identity. But is it?
11. Knowledge Aims / B. Certain Knowledge / 4. The Cogito
I cannot think my non-existence, nor exist without being myself [Leibniz]
     Full Idea: I am assured that as long as I think, I am myself. For I cannot think that I do not exist, nor exist so that I be not myself.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.05.13)
     A reaction: Elsewhere he qualifies the Cogito, but here he seems to straighforwardly endorse it.
11. Knowledge Aims / B. Certain Knowledge / 5. Cogito Critique
I can't just know myself to be a substance; I must distinguish myself from others, which is hard [Leibniz]
     Full Idea: It is not enough for understanding the nature of myself, that I feel myself to be a thinking substance, one would have to form a distinct idea of what distinguishes me from all other possible minds; but of that I have only a confused experience.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.07.4/14)
     A reaction: Not a criticism I have encountered before. Does he mean that I might be two minds, or might be a multitude of minds? It seems to be Hume's problem, that you are aware of experiences, but not of the substance that unites them.
12. Knowledge Sources / B. Perception / 5. Interpretation
We see an approximation of a tree, not the full detail [Nietzsche]
     Full Idea: We do not see a tree exactly and entire with regard to its leaves, branches, colour and shape; it is so much easier for us to see an approximation of a tree.
     From: Friedrich Nietzsche (Beyond Good and Evil [1886], §192)
13. Knowledge Criteria / B. Internal Justification / 2. Pragmatic justification
We shouldn't object to a false judgement, if it enhances and preserves life [Nietzsche]
     Full Idea: The falseness of a judgement is to us not necessarily an objection to a judgement. To what extent is it life-advancing, life-preserving, species-preserving. Our fundamental tendency is to assert that our falsest judgements are the most indispensable.
     From: Friedrich Nietzsche (Beyond Good and Evil [1886], §004)
     A reaction: This is the standard objection to pragmatism, that what is false may still be useful, and that clever blighter Nietzsche embraces the idea!
13. Knowledge Criteria / B. Internal Justification / 4. Foundationalism / a. Foundationalism
Nothing should be taken as certain without foundations [Leibniz]
     Full Idea: Nothing should be taken as certain without foundations.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1687.04.30)
     A reaction: This might leave open the option, if you were a modern 'Fallibilist', that something might lack foundations, and so not be certain, and yet still qualify as 'knowledge'. That is my view. Knowledge resides somewhere between opinion and certainty.
13. Knowledge Criteria / E. Relativism / 4. Cultural relativism
Morality becomes a problem when we compare many moralities [Nietzsche]
     Full Idea: The real problems of morality come into view only if we compare many moralities.
     From: Friedrich Nietzsche (Beyond Good and Evil [1886], §186)
14. Science / D. Explanation / 2. Types of Explanation / a. Types of explanation
Nature is explained by mathematics and mechanism, but the laws rest on metaphysics [Leibniz]
     Full Idea: One must always explain nature along mathematical and mechanical lines, provided one knows that the very principles or laws of mechanics or of force do not depend upon mathematical extension alone but upon certain metaphysical reasons.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.07.4/14 X)
     A reaction: I like this, and may even use it as the epigraph of my masterwork. Recently Stephen Hawking (physicist) has been denigrating philosophy, but I am with Leibniz on this one.
14. Science / D. Explanation / 2. Types of Explanation / k. Explanations by essence
To fully conceive the subject is to explain the resulting predicates and events [Leibniz]
     Full Idea: Even in the most contingent truths, there is always something to be conceived in the subject which serves to explain why this predicate or event pertains to it, or why this has happened rather than not.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.06)
     A reaction: The last bit, about containing what has happened, seems absurd, but the rest of it makes sense. It is just the Aristotelian essentialist view, that a full understanding of the inner subject will both explain and predict the surface properties.
15. Nature of Minds / A. Nature of Mind / 1. Mind / b. Purpose of mind
Mind is a thinking substance which can know God and eternal truths [Leibniz]
     Full Idea: Minds are substances which think, and are capable of knowing God and of discovering eternal truths.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1687.10.09)
     A reaction: 'God' is there because the ability to grasp the ontological argument is seen as basic. Note a firm commitment to substance-dualism, and a rationalist commitment to the spotting of necessary truths as basic. He is not totally wrong.
15. Nature of Minds / A. Nature of Mind / 7. Animal Minds
It seems probable that animals have souls, but not consciousness [Leibniz]
     Full Idea: It appears probable that the brutes have souls, though they are without consciousness.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.12.08)
     A reaction: This will be a response to Descartes, who allowed animals sensations, but not minds or souls. Personally I cannot make head or tail of Leibniz's claim. What makes it "apparent" to him?
15. Nature of Minds / C. Capacities of Minds / 10. Conatus/Striving
The ranking of a person's innermost drives reveals their true nature [Nietzsche]
     Full Idea: To know 'who he is', we must know the order of rank the innermost drives of his nature stand in relative to one another.
     From: Friedrich Nietzsche (Beyond Good and Evil [1886], §006)
     A reaction: This is clearly an essentialist view of a person, as having a 'nature', which is 'inner', and which we can try to specify. Ranking drives and values seems a good proposal for getting at it. I'm also intrigued by what people find interesting.
16. Persons / F. Free Will / 5. Against Free Will
A thought comes when 'it' wants, not when 'I' want [Nietzsche]
     Full Idea: A thought comes when 'it' wants, not when 'I' want.
     From: Friedrich Nietzsche (Beyond Good and Evil [1886], §017)
     A reaction: A wonderful remark (which I have since found in Schopenhauer). I don't see how the most enthusiastic free will libertarian can deny it.
Wanting 'freedom of will' is wanting to pull oneself into existence out of the swamp of nothingness by one's own hair [Nietzsche]
     Full Idea: The desire for 'freedom of will' is nothing less than the desire to pull oneself into existence out of the swamp of nothingness by one's own hair.
     From: Friedrich Nietzsche (Beyond Good and Evil [1886], §021)
16. Persons / F. Free Will / 7. Compatibilism
Everything which happens is not necessary, but is certain after God chooses this universe [Leibniz]
     Full Idea: It is not the case that everything which happens is necessary; rather, everything which happens is certain after God made choice of this possible universe, whose notion contains this series of things.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.05)
     A reaction: I think this distinction is best captured as 'metaphysical necessity' (Leibniz's 'necessity'), and 'natural necessity' (his 'certainty'). 'Certainty' seems a bad word, as it is either certain de dicto or de re. Is God certain, or is the thing certain?
18. Thought / B. Mechanics of Thought / 1. Psychology
It is psychology which reveals the basic problems [Nietzsche]
     Full Idea: Psychology is now once again the road to the fundamental problems.
     From: Friedrich Nietzsche (Beyond Good and Evil [1886], §023)
     A reaction: This may become the epigraph of my great book, which will have as working title 'The Psychology of Metaphysics'. If you trawl through this collection, you will see where I am going! (A tough job, but easier than reading Hegel).
18. Thought / D. Concepts / 1. Concepts / a. Nature of concepts
Concepts are what unite a proposition [Leibniz]
     Full Idea: There must always be some basis for the connexion between the terms of a proposition, and it is to be found in their concepts.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.07.4/14 X)
     A reaction: We face the problem that bothered Russell, of the unity of the proposition. We are also led to the question of HOW our concepts connect the parts of a proposition. Do concepts have valencies? Are they incomplete, as Frege suggests?
21. Aesthetics / A. Aesthetic Experience / 4. Beauty
Beauty increases with familiarity [Leibniz]
     Full Idea: The more one is familiar with things, the more beautiful one finds them.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1688.01.4/14)
     A reaction: This is always the reply given to those who say that science kills our sense of beauty. The first step in aesthetic life is certainly to really really pay attention to things.
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / a. Idealistic ethics
The most boring and dangerous of all errors is Plato's invention of pure spirit and goodness [Nietzsche]
     Full Idea: The worst, most wearisomely protracted and most dangerous of all errors hitherto has been a dogmatist's error, namely Plato's invention of pure spirit and the good in itself.
     From: Friedrich Nietzsche (Beyond Good and Evil [1886], Pref)
     A reaction: A landmark observation about the history of philosophy. Imagine if all the Aristotle had survived, but all the Plato had been lost.
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / d. Biological ethics
Nietzsche felt that Plato's views downgraded the human body and its brevity of life [Nietzsche, by Roochnik]
     Full Idea: Nietzsche believed that by elevating the importance of the mind, Plato downplayed the wonders of the body, and by searching for a timeless Truth he degraded the indisputable fact of human temporality.
     From: report of Friedrich Nietzsche (Beyond Good and Evil [1886], Pref) by David Roochnik - The Tragedy of Reason Prol. X
     A reaction: Both ideas are very important. The second is widely misunderstood. Nietzsche was not a denier of truth. He asked us to scrutinise the role and value we assign to truth.
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / f. Übermensch
Noble people see themselves as the determiners of values [Nietzsche]
     Full Idea: The noble type of man feels himself to be the determiner of values.
     From: Friedrich Nietzsche (Beyond Good and Evil [1886], §260)
     A reaction: So do criminals
Nietzsche's judgement of actions by psychology instead of outcome was poisonous [Foot on Nietzsche]
     Full Idea: Nietzsche wants to judge actions not by what is done, but by the nature of the person who does them, and that is poisonous. We have to be horrified by what is done by Hitler and Stalin, without inquiring into their psychology.
     From: comment on Friedrich Nietzsche (Beyond Good and Evil [1886]) by Philippa Foot - Interview with Philippa Foot p.37
     A reaction: She says morality should focus on social needs, not on spontaneity, energy and passion. Nietzsche was very much a product of romanticism. Some of Nietzsche's heroes are military conquerors, so I think she is right.
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / j. Ethics by convention
That which is done out of love always takes place beyond good and evil [Nietzsche]
     Full Idea: That which is done out of love always takes place beyond good and evil.
     From: Friedrich Nietzsche (Beyond Good and Evil [1886], §153)
     A reaction: He is referring to the conventional morality of his contemporary society. Nietzsche clearly thought that actions motivated by love are intrinsically good. (Apart from murders by the jealous!).
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / k. Ethics from nature
Nature is totally indifferent, so you should try to be different from it, not live by it [Nietzsche]
     Full Idea: You Stoics want to "live according to nature"? Oh you noble Stoics, what fraudulent words! Nature is prodigal and indifferent beyond measure - how could you live by such indifference? Living is wanting to be other than nature.
     From: Friedrich Nietzsche (Beyond Good and Evil [1886], §009)
     A reaction: I think this is simply indicative of the slide from optimism to pessimism about nature in the intervening centuries. Stoics thought nature rational. See 'King Lear' for the transition.
22. Metaethics / C. The Good / 1. Goodness / c. Right and good
Morality originally judged people, and actions only later on [Nietzsche]
     Full Idea: Designation of moral values was everywhere first applied to human beings, and only later and derivatively to actions.
     From: Friedrich Nietzsche (Beyond Good and Evil [1886], §260)
     A reaction: Nietzsche was a great expert on ethics in the ancient world, so you should trust him on this one. In ordinary life assessment of people is what counts. Actions are for law courts.
22. Metaethics / C. The Good / 1. Goodness / g. Consequentialism
In the earliest phase of human history only consequences mattered [Nietzsche]
     Full Idea: Throughout the longest part of history ('prehistoric times') the value or non-value of an action was derived from its consequences. …but now men are unanimous that the value of an action is in the intention behind it.
     From: Friedrich Nietzsche (Beyond Good and Evil [1886], §032)
     A reaction: This seems to be Kant's fault. No one thinks that a reckless or malicios action is innocent if no actual harm results.
22. Metaethics / C. The Good / 2. Happiness / a. Nature of happiness
Happiness is advancement towards perfection [Leibniz]
     Full Idea: Happiness, or lasting contentment, consists of continual advancement towards a greater perfection.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1690.03.23)
     A reaction: To the modern mind this smacks of the sort of hubris to which only the religious mind can aspire, but it's still rather nice. The idea of grubby little mammals approaching perfection sounds wrong, but which other animal has even thought of perfection?
23. Ethics / A. Egoism / 1. Ethical Egoism
The noble soul has reverence for itself [Nietzsche]
     Full Idea: The noble soul has reverence for itself.
     From: Friedrich Nietzsche (Beyond Good and Evil [1886], §287)
23. Ethics / C. Virtue Theory / 1. Virtue Theory / c. Particularism
Moralities extravagantly address themselves to 'all', by falsely generalising [Nietzsche]
     Full Idea: All moralities are baroque and unreasonable ...because they address themselves to 'all', because they generalise where one must not generalise.
     From: Friedrich Nietzsche (Beyond Good and Evil [1886], §198)
     A reaction: 'Particularism' is a recent label, but one finds passing remarks from many earlier philosophers which support that approach to ethics. No one was ever more opposed to strict moral rules than Nietzsche.
23. Ethics / C. Virtue Theory / 1. Virtue Theory / d. Virtue theory critique
Virtue has been greatly harmed by the boringness of its advocates [Nietzsche]
     Full Idea: May I be forgiven for the discovery that 'virtue' has been harmed by nothing more than it has been by the boringness of its advocates.
     From: Friedrich Nietzsche (Beyond Good and Evil [1886], §228)
23. Ethics / C. Virtue Theory / 3. Virtues / a. Virtues
The four virtues are courage, insight, sympathy, solitude [Nietzsche]
     Full Idea: To remain master of one's four virtues: courage, insight, sympathy, solitude.
     From: Friedrich Nietzsche (Beyond Good and Evil [1886], §284)
     A reaction: Compare this with 'Daybreak (Dawn)' 556. Solitude is the surprising addition, defended as the urge to 'cleanliness', when since humanity is 'unclean'.
23. Ethics / C. Virtue Theory / 3. Virtues / f. Compassion
In ancient Rome pity was considered neither good nor bad [Nietzsche]
     Full Idea: An act of pity was during the finest age of Rome considered neither good nor bad.
     From: Friedrich Nietzsche (Beyond Good and Evil [1886], §201)
23. Ethics / D. Deontological Ethics / 4. Categorical Imperative
The idea of the categorical imperative is just that we should all be very obedient [Nietzsche]
     Full Idea: What does the claim that there exists in us a categorical imperative say of the man who asserts it? …that 'what is worthy of respect in me is that I know how to obey - and things ought to be no different with you'.
     From: Friedrich Nietzsche (Beyond Good and Evil [1886], §187)
23. Ethics / E. Utilitarianism / 3. Motivation for Altruism
The morality of slaves is the morality of utility [Nietzsche]
     Full Idea: Slave morality is essentially the morality of utility.
     From: Friedrich Nietzsche (Beyond Good and Evil [1886], §261)
23. Ethics / F. Existentialism / 1. Existentialism
The greatest possibilities in man are still unexhausted [Nietzsche]
     Full Idea: The greatest possibilities in man are still unexhausted.
     From: Friedrich Nietzsche (Beyond Good and Evil [1886], §203)
23. Ethics / F. Existentialism / 3. Angst
The thought of suicide is a great reassurance on bad nights [Nietzsche]
     Full Idea: The thought of suicide is a powerful solace: by means of it one gets through many a bad night.
     From: Friedrich Nietzsche (Beyond Good and Evil [1886], §157)
The freedom of the subject means the collapse of moral certainty [Nietzsche, by Critchley]
     Full Idea: In the 1880s Nietzsche diagnosed the concept of nihilism for a whole range of continental thinkers: the recognition of the subject's freedom goes hand in hand with the collapse of moral certainty in the world.
     From: report of Friedrich Nietzsche (Beyond Good and Evil [1886]) by Simon Critchley - Continental Philosophy - V. Short Intro Ch.5
     A reaction: Avoiding this dilemma is just one of the many bonuses offered to those who abandon the idea of free will. The fact that one can decide to be wicked doesn't bring an end to morality. Philosophers should think more concretely about human life.
23. Ethics / F. Existentialism / 6. Authentic Self
Nietzsche thinks the human condition is to overcome and remake itself [Nietzsche, by Ansell Pearson]
     Full Idea: Nietzsche thinks that the human condition is precisely to overcome itself; we continually remake ourselves.
     From: report of Friedrich Nietzsche (Beyond Good and Evil [1886]) by Keith Ansell Pearson - Interview with Baggini and Stangroom p.261
     A reaction: This is why I think of Nietzsche as a straightforwardly existentialist philosopher. There is a crucial distinction between 'remaking' ourselves and 'realising all our possibilities'. The latter seems right. Which view did Nietzsche take?
Man is the animal whose nature has not yet been fixed [Nietzsche]
     Full Idea: Man is the animal whose nature has not yet been fixed.
     From: Friedrich Nietzsche (Beyond Good and Evil [1886], §062)
23. Ethics / F. Existentialism / 8. Eternal Recurrence
The great person engages wholly with life, and is happy to endlessly relive the life they created [Nietzsche]
     Full Idea: There is an ideal ...of the most exuberant, most living and most world-affirming man, who has not only learned to get on and treat with all that was and is, but who wants to have it again as it was and is to all eternity.
     From: Friedrich Nietzsche (Beyond Good and Evil [1886], §056)
     A reaction: This seems to be the main point of the idea of eternal recurrence. Could we inculcate this vision into the teenagers of our nation - that they should each try to design for themselves a life which they would be happy to endlessly repeat? Hm.
24. Political Theory / C. Ruling a State / 2. Leaders / d. Elites
Only aristocratic societies can elevate the human species [Nietzsche]
     Full Idea: Every elevation of the type 'man' has thitherto been the work of an aristocratic society - and so it will always be: a society which believes in a long scale of orders of rank and differences of worth between man and man, and needs slavery in some sense.
     From: Friedrich Nietzsche (Beyond Good and Evil [1886], §257)
     A reaction: The aim of 'elevating the type "man"' does not figure in works of political philosophy very much! I doubt whether one could base a political party on the idea, and win a general election. Could the people still be sold the idea of aristocracy?
A healthy aristocracy has no qualms about using multitudes of men as instruments [Nietzsche]
     Full Idea: A good and healthy aristocracy ...accepts with a good conscience the sacrifice of innumerable men who for its sake have to be suppressed and reduced to imperfect men, to slaves and instruments.
     From: Friedrich Nietzsche (Beyond Good and Evil [1886], §258)
     A reaction: Something similar might be said of a democracy - that a slavelike workforce is needed to create the great universal goods we all want and need. Do the aristocrats want sacrifices for great art, or for wild parties and fox hunting?
24. Political Theory / D. Ideologies / 5. Democracy / f. Against democracy
Democracy diminishes mankind, making them mediocre and lowering their value [Nietzsche]
     Full Idea: To us the democratic movement is ...a form of decay, namely the diminution, of man, making him mediocre and lowering his value.
     From: Friedrich Nietzsche (Beyond Good and Evil [1886], §203), quoted by Philippa Foot - Nietzsche: the Revaluation of Values p.88
     A reaction: It is not clear how a society of natural aristocrats followed by sheep would increase the value of mankind. Nor if the talented people are given total freedom, and the rest of us are servants. The value of humanity cannot reside in a few individuals.
26. Natural Theory / A. Speculations on Nature / 6. Early Matter Theories / g. Atomism
I think the corpuscular theory, rather than forms or qualities, best explains particular phenomena [Leibniz]
     Full Idea: I still subscribe fully to the corpuscular theory in the explanation of particular phenomena; in this sphere it is of no value to speak of forms or qualities.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 14.07.1686)
     A reaction: I am puzzled by Garber's summary in Idea 12728, and a bit unclear on Leibniz's views on atoms. More needed.
26. Natural Theory / D. Laws of Nature / 1. Laws of Nature
Each possible world contains its own laws, reflected in the possible individuals of that world [Leibniz]
     Full Idea: As there exist an infinite number of possible worlds, there exists also an infinite number of laws, some peculiar to one world, some to another, and each individual of any one world contains in the concept of him the laws of his world.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.06)
     A reaction: Since Leibniz's metaphysics is thoroughly God-driven, he will obviously allow God to create any laws He wishes, and hence scientific essentialism seems to be rejected, even though Leibniz is keen on essences. Unless the stuff is different...
27. Natural Reality / A. Classical Physics / 1. Mechanics / c. Forces
Motion alone is relative, but force is real, and establishes its subject [Leibniz]
     Full Idea: Motion in itself separated from force is merely relative, and one cannot establish its subject. But force is something real and absolute.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1688.01.4/14)
     A reaction: The striking phrase here is that force enables us to 'establish its subject'. That is, force is at the heart of reality, and hence, through causal relations, individuates objects. That's how I read it.
28. God / B. Proving God / 3. Proofs of Evidence / e. Miracles
Everything, even miracles, belongs to order [Leibniz]
     Full Idea: Everything, even miracles, belongs to order.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.07.4/14 X)
     A reaction: This is very reminiscent of Plato, for whom there was no more deeply held belief than that the cosmos is essentially orderly. Coincidences are a nice problem, if they are events with no cause.
Miracles are extraordinary operations by God, but are nevertheless part of his design [Leibniz]
     Full Idea: Miracles, or the extraordinary operations of God, none the less belong within the general order; they are in conformity with the principal designs of God, and consequently are included in the notion of this universe, which is the result of those designs.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.05)
     A reaction: Some philosophers just make up things to suit themselves. What possible grounds can he have for claiming this? At best this is tautological, saying that, by definition, if anything at all happens, it must be part of God's design. Move on to Hume…
29. Religion / B. Monotheistic Religion / 4. Christianity / a. Christianity
Christianity is Platonism for the people [Nietzsche]
     Full Idea: Christianity is Platonism for the people.
     From: Friedrich Nietzsche (Beyond Good and Evil [1886], Pref)
29. Religion / D. Religious Issues / 2. Immortality / a. Immortality
Immortality without memory is useless [Leibniz]
     Full Idea: Immortality without memory would be useless.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.07.4/14 X)
     A reaction: I would say that having a mind of any sort needs memory. The question for immortality is whether it extends back to human life. See 'Wuthering Heights' (c. p90) for someone who remembers Earth as so superior to paradise that they long to return there.
29. Religion / D. Religious Issues / 2. Immortality / b. Soul
The soul is indestructible and always self-aware [Leibniz]
     Full Idea: Not only is the soul indestructible, but it always knows itself and remains self-conscious.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.11)
     A reaction: Personally I am not even self-aware during much of my sleeping hours, and I would say that I cease to be self-aware if I am totally absorbed in something on which I concentrate.
29. Religion / D. Religious Issues / 2. Immortality / c. Animal Souls
Animals have souls, but lack consciousness [Leibniz]
     Full Idea: It appears probable that animals have souls although they lack consciousness.
     From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.11)
     A reaction: Personally I would say that they lack souls but have consciousness, but then I am in no better position to know the answer than Leibniz was. Arnauld asks what would happen to the souls of 100,000 silkworms if they caught fire!
