1. Philosophy / B. History of Ideas / 5. Later European Thought
Since Kant we think we can only access 'correlations' between thinking and being [Meillassoux]
     Full Idea: The central notion of philosophy since Kant is 'correlation' - that we only ever have access to the correlation between thinking and being, and never to either term considered apart from the other.
     From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 1)
     A reaction: Meillassoux's charge is that philosophy has thereby completely failed to grasp the scientific revolution, which has used mathematics to make objectivity possible. Quine and Putnam would be good examples of what he has in mind.
The Copernican Revolution decentres the Earth, but also decentres thinking from reality [Meillassoux]
     Full Idea: The Copernican Revolution is not so much the decentring of observers in the solar system, but (by the mathematizing of nature) the decentring of thought relative to the world within the process of knowledge.
     From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 5)
     A reaction: In other words, I take it, the Copernican Revolution was the discovery of objectivity. That is a very nice addition to my History of Ideas collection.
1. Philosophy / B. History of Ideas / 6. Twentieth Century Thought
In Kant the thing-in-itself is unknowable, but for us it has become unthinkable [Meillassoux]
     Full Idea: The major shift that has occurred in the conception of thought from Kant's time to ours is from the unknowability of the thing-in-itself to its unthinkability.
     From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 2)
     A reaction: Meillassoux is making the case that philosophy is alienating us more and more from the triumphant realism of the scientific revolution. He says thinking has split from being. He's right. Modern American pragmatists are the worst (not Peirce!).
1. Philosophy / D. Nature of Philosophy / 5. Aims of Philosophy / e. Philosophy as reason
Definitions are the first step in philosophy [Hobbes]
     Full Idea: In beginning philosophy, the first beginning is from definitions.
     From: Thomas Hobbes (De Corpore (Elements, First Section) [1655], 1.6.15)
     A reaction: Note that he doesn't say that definitions are the aim of philosophy, as some analysts might think.
1. Philosophy / G. Scientific Philosophy / 3. Scientism
Since Kant, philosophers have claimed to understand science better than scientists do [Meillassoux]
     Full Idea: Ever since Kant, to think science as a philosopher has been to claim that science harbours a meaning other than the one delivered by science itself.
     From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 5)
     A reaction: The point is that science discovered objectivity (via the mathematising of nature), and Kant utterly rejected objectivity, by enmeshing the human mind in every possible scientific claim. This makes Meillassoux and I very cross.
2. Reason / A. Nature of Reason / 5. Objectivity
Since Kant, objectivity is defined not by the object, but by the statement's potential universality [Meillassoux]
     Full Idea: Since Kant, objectivity is no longer defined with reference to the object in itself, but rather with reference to the possible universality of an objective statement.
     From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 1)
     A reaction: Meillassoux disapproves of this, as a betrayal by philosophers of the scientific revolution, which gave us true objectivity (e.g. about how the world was before humanity).
2. Reason / B. Laws of Thought / 2. Sufficient Reason
If we insist on Sufficient Reason the world will always be a mystery to us [Meillassoux]
     Full Idea: So long as we continue to believe that there is a reason why things are the way they are rather than some other way, we will construe this world is a mystery, since no such reason will every be vouchsafed to us.
     From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 4)
     A reaction: Giving up sufficient reason sounds like a rather drastic response to this. Put it like this: Will we ever be able to explain absolutely everything? No. So will the world always be a little mysterious to us? Yes, obviously. Is that a problem? No!
2. Reason / B. Laws of Thought / 3. Non-Contradiction
Non-contradiction is unjustified, so it only reveals a fact about thinking, not about reality? [Meillassoux]
     Full Idea: The principle of non-contradiction itself is without reason, and consequently it can only be the norm for what is thinkable by us, rather than for what is possible in the absolute sense.
     From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 2)
     A reaction: This is not Meillassoux's view, but describes the modern heresy of 'correlationism', which ties all assessments of how reality is to our capacity to think about it. Personally I take logical non-contradiction to derive from non-contradiction in nature.
2. Reason / D. Definition / 2. Aims of Definition
Definitions of things that are caused must express their manner of generation [Hobbes]
     Full Idea: Definitions of things which may be understood to have some cause, must consist of such names as express the cause or manner of their generation, as when we define a circle to be a figure made by the circumduction of a straight line in a plane etc.
     From: Thomas Hobbes (De Corpore (Elements, First Section) [1655], 1.6.13)
     A reaction: His account of the circle is based on its mode of construction, which is the preferred account of Euclid, rather than a statement of its pure nature.
2. Reason / D. Definition / 5. Genus and Differentia
Definition is resolution of names into successive genera, and finally the difference [Hobbes]
     Full Idea: The definition is nothing but a resolution of the name into its most universal parts; ...definitions of this kind always consist of genus and difference; the former names being all, till the last, general; and the last of all, difference.
     From: Thomas Hobbes (De Corpore (Elements, First Section) [1655], 1.6.14)
     A reaction: This is basically the scholastic Aristotelian view of definition. Note that Hobbes explicitly denies that the last step of the definition is general in character.
2. Reason / D. Definition / 8. Impredicative Definition
A defined name should not appear in the definition [Hobbes]
     Full Idea: A defined name ought not to be repeated in the definition. ...No total can be part of itself.
     From: Thomas Hobbes (De Corpore (Elements, First Section) [1655], 1.6.15)
2. Reason / F. Fallacies / 3. Question Begging
'Petitio principii' is reusing the idea to be defined, in disguised words [Hobbes]
     Full Idea: 'Petitio principii' is when the conclusion to be proved is disguised in other words, and put for the definition or principle from whence it is to be demonstrated.
     From: Thomas Hobbes (De Corpore (Elements, First Section) [1655], 1.6.18)
4. Formal Logic / E. Nonclassical Logics / 7. Paraconsistency
We can allow contradictions in thought, but not inconsistency [Meillassoux]
     Full Idea: For contemporary logicians, it is not non-contradiction that provides the criterion for what is thinkable, but rather inconsistency.
     From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 3)
     A reaction: The point is that para-consistent logic might permit isolated contradictions (as true) within a system, but it is only contradiction across the system (inconsistencies) which make the system untenable.
Paraconsistent logics are to prevent computers crashing when data conflicts [Meillassoux]
     Full Idea: Paraconsistent logics were only developed in order to prevent computers, such as expert medical systems, from deducing anything whatsoever from contradictory data, because of the principle of 'ex falso quodlibet'.
     From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 3)
Paraconsistent logic is about statements, not about contradictions in reality [Meillassoux]
     Full Idea: Paraconsistent logics are only ever dealing with contradictions inherent in statements about the world, never with the real contradictions in the world.
     From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 3)
     A reaction: Thank goodness for that! I can accept that someone in a doorway is both in the room and not in the room, but not that they are existing in a real state of contradiction. I fear that a few daft people embrace the logic as confirming contradictory reality.
4. Formal Logic / G. Formal Mereology / 3. Axioms of Mereology
A part of a part is a part of a whole [Hobbes]
     Full Idea: A part of a part is a part of a whole.
     From: Thomas Hobbes (De Corpore (Elements, First Section) [1655], 2.07.09)
6. Mathematics / A. Nature of Mathematics / 3. Nature of Numbers / e. Ordinal numbers
If we just say one, one, one, one, we don't know where we have got to [Hobbes]
     Full Idea: By saying one, one, one, one, and so forward, we know not what number we are at beyond two or three.
     From: Thomas Hobbes (De Corpore (Elements, First Section) [1655], 2.12.05)
     A reaction: This makes ordinals sound like meta-numbers.
6. Mathematics / A. Nature of Mathematics / 4. Using Numbers / g. Applying mathematics
What is mathematically conceivable is absolutely possible [Meillassoux]
     Full Idea: We must establish the thesis that what is mathematically conceivable is absolutely possible.
     From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 5)
     A reaction: The truth of this thesis would permanently establish mathematics as the only possible language of science. Personally I have no idea how you could prove or assess such a thesis. It is a lovely speculation, though. 'The structure of the possible' (p,127)
7. Existence / A. Nature of Existence / 1. Nature of Existence
The absolute is the impossibility of there being a necessary existent [Meillassoux]
     Full Idea: We maintain that it is absolutely necessary that every entity might not exist. ...The absolute is the absolute impossibility of a necessary being.
     From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 3)
     A reaction: This is the main thesis of his book. The usual candidates for necessary existence are God, and mathematical objects. I am inclined to agree with Meillassoux.
7. Existence / A. Nature of Existence / 5. Reason for Existence
It is necessarily contingent that there is one thing rather than another - so something must exist [Meillassoux]
     Full Idea: It is necessary that there be something rather than nothing because it is necessarily contingent that there is something rather than something else.
     From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 3)
     A reaction: The great charm of metaphysics is the array of serious answers to the question of why there is something rather than nothing. You'll need to read Meillassoux's book to understand this one.
7. Existence / A. Nature of Existence / 6. Criterion for Existence
We must give up the modern criterion of existence, which is a correlation between thought and being [Meillassoux]
     Full Idea: It is incumbent upon us to break with the ontological requisite of the moderns, according to which 'to be is to be a correlate'.
     From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 2)
     A reaction: He blames Kant for this pernicious idea, which has driven philosophy away from realist science, when it should be supporting and joining it. As a realist I agree, and find Meillassoux very illuminating on the subject.
7. Existence / B. Change in Existence / 1. Nature of Change
Change is nothing but movement [Hobbes]
     Full Idea: All mutation consists in motion only
     From: Thomas Hobbes (De Corpore (Elements, First Section) [1655], 2.09.06)
     A reaction: Another little gem of simplicity from Hobbes, and one with which I am inclined to agree. The value of a variable can 'change', but that may be metaphorical.
8. Modes of Existence / B. Properties / 8. Properties as Modes
Accidents are just modes of thinking about bodies [Hobbes]
     Full Idea: An accident is a mode of conceiving a body.
     From: Thomas Hobbes (De Corpore (Elements, First Section) [1655], 2.08.02)
     A reaction: In contrast to the other thinkers who followed Suárez on modes in the early 17th century, Hobbes thinks they are just ways of 'conceiving' bodies, rather than actual features of them.
8. Modes of Existence / B. Properties / 12. Denial of Properties
Accidents are not parts of bodies (like blood in a cloth); they have accidents as things have a size [Hobbes]
     Full Idea: An accident's being in a body is not to be taken as something contained in that body - as if redness were in blood like blood in a bloody cloth, as part of the whole, for then accident would be a body. It is like body having size or rest or movement.
     From: Thomas Hobbes (De Corpore (Elements, First Section) [1655], 2.08.03)
     A reaction: [compressed] Hobbes is fishing for something like the Quinean view of properties, but no one seems to be able to articulate this sceptical view very well. Pasnau says he means to talk of 'the mode of conceiving a body' (De C 8.2).
8. Modes of Existence / C. Powers and Dispositions / 3. Powers as Derived
The complete power of an event is just the aggregate of the qualities that produced it [Hobbes]
     Full Idea: The power of agent and patient taken together, which may be called the complete power, is the same as the complete cause, for each consists in the aggregation together of all the accidents that are required to produce an effect in both agent and patient.
     From: Thomas Hobbes (De Corpore (Elements, First Section) [1655], 2.10.01)
     A reaction: They treat powers as macro phenomena, and don't seem to have a sense of the basic powers that build up the big picture.
8. Modes of Existence / E. Nominalism / 1. Nominalism / b. Nominalism about universals
The only generalities or universals are names or signs [Hobbes]
     Full Idea: Nothing is general or universal besides names or signs.
     From: Thomas Hobbes (De Corpore (Elements, First Section) [1655], 2.08.05)
     A reaction: This is the perfect motto for nominalists, among which I am inclined to include myself. Hobbes had a fabulous gift for economy of phrasing. This website is dedicated to that ideal. Reality does not contain generalities (obviously!!).
9. Objects / A. Existence of Objects / 5. Individuation / c. Individuation by location
Bodies are independent of thought, and coincide with part of space [Hobbes]
     Full Idea: A body is that, which having no dependence on our thought, is coincident or coextended with some part of space.
     From: Thomas Hobbes (De Corpore (Elements, First Section) [1655], 2.08.01)
     A reaction: This rather Cartesian view doesn't seem to offer any distinction between empty space and space containing an 'object'. Presumably it is the ancestor of the Quinean account just in terms of space-time points. Don't like it.
If you separate the two places of one thing, you will also separate the thing [Hobbes]
     Full Idea: One body cannot be in two places at the same time, ...for the place that a body fills being divided into two, the placed body will also be divided into two; the place and the body that fills that place are divided both together.
     From: Thomas Hobbes (De Corpore (Elements, First Section) [1655], 2.08.08)
     A reaction: If every time you manipulated one body it affected both of them, you might say that one body was in two places, rather like a mirror image.
If you separated two things in the same place, you would also separate the places [Hobbes]
     Full Idea: Two bodies cannot be together in the same place, ..because when a body that fills its whole place is divided into two, the place itself is divided into two also, so that there will be two places.
     From: Thomas Hobbes (De Corpore (Elements, First Section) [1655], 2.08.08)
     A reaction: The wonderful things about philosophy is that you are faced with obvious truths of the world, and cannot begin to think why they are true - and then up steps a philosopher and offers you a reason.
9. Objects / B. Unity of Objects / 1. Unifying an Object / b. Unifying aggregates
If a whole body is moved, its parts must move with it [Hobbes]
     Full Idea: How can any whole body be moved, unless all its parts be moved together with it?
     From: Thomas Hobbes (De Corpore (Elements, First Section) [1655], 2.08.05)
     A reaction: This might be a distinguishing mark for a whole physical body. I think it is probably the main mark for ordinary folk. I've never found this idea in Aristotle.
9. Objects / C. Structure of Objects / 8. Parts of Objects / b. Sums of parts
A body is always the same, whether the parts are together or dispersed [Hobbes]
     Full Idea: A body is always the same, whether the parts of it be put together or dispersed; or whether it be congealed or dissolved.
     From: Thomas Hobbes (De Corpore (Elements, First Section) [1655], 2.11.07)
     A reaction: This appears to be a commitment by Hobbes to what we now call 'classical' mereology - that any bunch of things can count as a whole, whether they are together or dispersed. He seems to mean more than a watch surviving dismantling.
9. Objects / C. Structure of Objects / 8. Parts of Objects / c. Wholes from parts
To make a whole, parts needn't be put together, but can be united in the mind [Hobbes]
     Full Idea: In composition, it is to be understood that for the making up of a whole there is no need of putting the parts together, so as to make them touch one another, but only of collecting them into one sum in the mind.
     From: Thomas Hobbes (De Corpore (Elements, First Section) [1655], 2.07.08)
     A reaction: This seems to the 'unrestricted composition' of classical mereology, since it appears that Hobbes offers no restriction on which parts can be united by a mind, no matter how bizarre.
9. Objects / D. Essence of Objects / 5. Essence as Kind
Particulars contain universal things [Hobbes]
     Full Idea: Universal things are contained in the nature of singular things.
     From: Thomas Hobbes (De Corpore (Elements, First Section) [1655], 1.6.04)
     A reaction: That is the neatest and most accurate summary of the situation I have ever read. Particulars come first, but they are all riddled with generalities (but that is not as well said as Hobbes's remark).
9. Objects / D. Essence of Objects / 7. Essence and Necessity / b. Essence not necessities
Some accidental features are permanent, unless the object perishes [Hobbes]
     Full Idea: There are certain accidents which can never perish except the body perish also.
     From: Thomas Hobbes (De Corpore (Elements, First Section) [1655], 2.08.03)
     A reaction: He is just making an observation, and not proposing a theory about essence.
9. Objects / D. Essence of Objects / 13. Nominal Essence
The feature which picks out or names a thing is usually called its 'essence' [Hobbes]
     Full Idea: That accident for which we give a certain name to any body, or the accident which denominates its subject, is commonly called the essence thereof.
     From: Thomas Hobbes (De Corpore (Elements, First Section) [1655], 2.08.23)
     A reaction: This is clearly a prelude to Locke's more carefully formulated 'nominal essence'. Fairly obvious, for nominalist empiricists. A bit surprising to say this was 'common'.
9. Objects / E. Objects over Time / 8. Continuity of Rivers
It is the same river if it has the same source, no matter what flows in it [Hobbes]
     Full Idea: That will be the same river which flows from one and the same fountain, whether the same water, or other water, or something other than water, flow thence.
     From: Thomas Hobbes (De Corpore (Elements, First Section) [1655], 2.11.07)
     A reaction: This makes the source the one necessity for a river. I think the end matters too. If the Thames reversed direction, and flowed into Wales, it would not be the Thames any more.
9. Objects / E. Objects over Time / 9. Ship of Theseus
Some individuate the ship by unity of matter, and others by unity of form [Hobbes]
     Full Idea: In the Ship of Theseus, some place individuity in the unity of matter; others, in the unity of form.
     From: Thomas Hobbes (De Corpore (Elements, First Section) [1655], 2.11.07)
     A reaction: Simons raises this comment into a dogma, that there are at least two objects present in the ship. If I offered you a sum for the contents of your house, they would have a unity of monetary value.
If a new ship were made of the discarded planks, would two ships be numerically the same? [Hobbes]
     Full Idea: If some man kept the old planks as they were taken out, and by putting them afterwards together again in the same order, had again made a ship of them, ...there would have been two ships numerically the same, which is absurd.
     From: Thomas Hobbes (De Corpore (Elements, First Section) [1655], 2.11.07)
     A reaction: This is the origin of the famous modern problematical example of the Ship of Theseus. The ancient example is just the case of whether you step into the same river, but using an artefact with parts, to make it clearer.
9. Objects / F. Identity among Objects / 3. Relative Identity
As an infant, Socrates was not the same body, but he was the same human being [Hobbes]
     Full Idea: It makes a great difference to ask concerning Socrates whether he is the same human being or whether he is the same body. For his body, when he is old, cannot be the same it was when he was an infant. …He can, however, be the same human being.
     From: Thomas Hobbes (De Corpore (Elements, First Section) [1655], 2.11.07)
     A reaction: This is not commitment to full (Geachian) relative identity, but it notes the problem.
9. Objects / F. Identity among Objects / 8. Leibniz's Law
Two bodies differ when (at some time) you can say something of one you can't say of the other [Hobbes]
     Full Idea: Two bodies are said to differ from one another, when something may be said of one of them, which cannot be said of the other at the same time.
     From: Thomas Hobbes (De Corpore (Elements, First Section) [1655], 2.11.02)
     A reaction: Note the astute addition of 'at the same time'. Note also that it is couched in terms of what is true, rather than in terms of 'properties' or 'accidents'.
10. Modality / B. Possibility / 5. Contingency
Possible non-being which must be realised is 'precariousness'; absolute contingency might never not-be [Meillassoux]
     Full Idea: My term 'precariousness' designates a possibility of not-being which must eventually be realised. By contrast, absolute contingency designates a pure possibility; one which may never be realised.
     From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 3)
     A reaction: I thoroughly approve of this distinction, because I have often enountered the assumption that all contingency is precariousness, and I have never seen why that should be so. In Aquinas's Third Way, for example. The 6 on a die may never come up.
10. Modality / B. Possibility / 7. Chance
The idea of chance relies on unalterable physical laws [Meillassoux]
     Full Idea: The very notion of chance is only conceivable on condition that there are unalterable physical laws.
     From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 4)
     A reaction: Laws might be contingent, even though they never alter. Chance in horse racing relies on the stability of whole institution of horse racing.
10. Modality / D. Knowledge of Modality / 4. Conceivable as Possible / b. Conceivable but impossible
We can imagine a point swelling and contracting - but not how this could be done [Hobbes]
     Full Idea: Even if we can feign in our mind that a point swells to a huge bulk and then contracts to a point - imagining something's made from nothing (ex nihilo), and nothing's made from something - still we cannot comprehend how this could be done in nature.
     From: Thomas Hobbes (De Corpore (Elements, First Section) [1655], 2.08.20)
     A reaction: [compressed] Pasnau notes that this offers two sorts of conceivability, of something happening, and of a reason for it happening. A really nice idea, significant (I think) for scientific essentialists, who say possibilities are fewer than you think.
11. Knowledge Aims / C. Knowing Reality / 3. Idealism / b. Transcendental idealism
Unlike speculative idealism, transcendental idealism assumes the mind is embodied [Meillassoux]
     Full Idea: What distinguishes transcendental idealism from speculative idealism is the fact that the former does not posit the existence of the transcendental subject apart from its bodily individuation.
     From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 1)
     A reaction: These modern French philosophers explain things so much more clearly than the English! The 'speculative' version is seen in Berkeley. On p.17 he says transcendental idealism is 'civilised', and speculative idealism is 'uncouth'.
12. Knowledge Sources / B. Perception / 2. Qualities in Perception / c. Primary qualities
The aspects of objects that can be mathematical allow it to have objective properties [Meillassoux]
     Full Idea: All aspects of the object that can give rise to a mathematical thought rather than to a perception or a sensation can be meaningfully turned into the properties of the thing not only as it is with me, but also as it is without me.
     From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 1)
     A reaction: This is Meillassoux's spin on the primary/secondary distinction, which he places at the heart of the scientific revolution. Cartesian dualism offers a separate space for the secondary qualities. He is appalled when philosophers reject the distinction.
14. Science / B. Scientific Theories / 1. Scientific Theory
How can we mathematically describe a world that lacks humans? [Meillassoux]
     Full Idea: How is mathematical discourse able to describe a reality where humanity is absent?
     From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 1)
     A reaction: He is referring to the prehistoric world. He takes this to be a key question about the laws of nature. We extrapolate mathematically from the experienced world, relying on the stability of the laws. Must they be necessary to be stable? No, it seems.
14. Science / C. Induction / 3. Limits of Induction
Hume's question is whether experimental science will still be valid tomorrow [Meillassoux]
     Full Idea: Hume's question can be formulated as follows: can we demonstrate that the experimental science which is possible today will still be possible tomorrow?
     From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 4)
     A reaction: Could there be deep universal changes going on in nature which science could never, even in principle, detect?
14. Science / D. Explanation / 2. Types of Explanation / g. Causal explanations
Science aims to show causes and generation of things [Hobbes]
     Full Idea: The end of science is the demonstration of the causes and generation of things.
     From: Thomas Hobbes (De Corpore (Elements, First Section) [1655], 1.6.13)
15. Nature of Minds / C. Capacities of Minds / 2. Imagination
Imagination is just weakened sensation [Hobbes]
     Full Idea: Imagination is nothing else but sense decaying or weakened by the absence of the object.
     From: Thomas Hobbes (De Corpore (Elements, First Section) [1655], 4.25.07)
     A reaction: This sounds more like memory than imagination. He needs to say something about unusual combinations of memories, I would have thought.
15. Nature of Minds / C. Capacities of Minds / 10. Conatus/Striving
A 'conatus' is an initial motion, experienced by us as desire or aversion [Hobbes, by Arthur,R]
     Full Idea: Hobbes' notion of 'conatus' is a 'beginning of motion' - a motion through a point of space in an instant of time. In a human subject this is experience as desire or aversion. It thus forms a bridge between physics and psychology.
     From: report of Thomas Hobbes (De Corpore (Elements, First Section) [1655], p.178) by Richard T.W. Arthur - Leibniz 3 'Worlds'
     A reaction: This sounds rather like the primitive concept of a power which I like, but the term seems to be used very vaguely, and never discussed carefully. The idea provoked Leibniz to connect physical force with mental life.
16. Persons / B. Nature of the Self / 4. Presupposition of Self
The transcendental subject is not an entity, but a set of conditions making science possible [Meillassoux]
     Full Idea: The transcendental subject simply cannot be said to exist; which is to say that the subject is not an entity, but rather a set of conditions rendering objective scientific knowledge of entities possible.
     From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 1)
     A reaction: Meillassoux treats this as part of the Kantian Disaster, which made an accurate account of the scientific revolution impossible for philosophers. Kant's ego seems to have primarily an epistemological role.
17. Mind and Body / E. Mind as Physical / 1. Physical Mind
Sensation is merely internal motion of the sentient being [Hobbes]
     Full Idea: Sense in the sentient, can be nothing else but motion in some of the internal parts of the sentient; and the parts so moved are parts of the organs of sense.
     From: Thomas Hobbes (De Corpore (Elements, First Section) [1655], 3.15.02)
     A reaction: Amazingly bold for the time, and presumably influenced by Lucretius. I am sympathetic, but to suggest that sensation is nothing more sounds a bit like a category mistake. Has he grasped that the brain is involved?
18. Thought / A. Modes of Thought / 3. Emotions / e. Basic emotions
Apart from pleasure and pain, the only emotions are appetite and aversion [Hobbes]
     Full Idea: All the passions, called passions of the mind, consist of appetite and aversion, except pure pleasure and pain.
     From: Thomas Hobbes (De Corpore (Elements, First Section) [1655], 4.25.13)
     A reaction: He now faces the challenge of explaining all the many other emotions in terms of these two. Good luck with that, Thomas.
18. Thought / B. Mechanics of Thought / 5. Mental Files
Words are not for communication, but as marks for remembering what we have learned [Hobbes]
     Full Idea: The use of words consists in this, that they may serve for marks by which whatsoever we have found out may be recalled to memory ...but not as signs by which we declare the same to others.
     From: Thomas Hobbes (De Corpore (Elements, First Section) [1655], 1.6.11)
     A reaction: This exactly fits the idea of mental files, of which I am a fan. That this is the actual purpose of language is an unusual but interesting view.
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.
26. Natural Theory / A. Speculations on Nature / 6. Early Matter Theories / b. Prime matter
Prime matter is body considered with mere size and extension, and potential [Hobbes]
     Full Idea: Prime matter signifies body considered without the consideration of any form or accident except only magnitude or extension, and aptness to receive form and accidents.
     From: Thomas Hobbes (De Corpore (Elements, First Section) [1655], 2.08.24)
     A reaction: I take 'considered without' to indicate that he thinks of it as a psychological abstraction, rather than some actual existing thing.
26. Natural Theory / C. Causation / 1. Causation
Acting on a body is either creating or destroying a property in it [Hobbes]
     Full Idea: A body is said to work upon or act, that is to say, do something to another body, when it either generates or destroys some accident in it.
     From: Thomas Hobbes (De Corpore (Elements, First Section) [1655], 2.09.01)
26. Natural Theory / C. Causation / 8. Particular Causation / c. Conditions of causation
An effect needs a sufficient and necessary cause [Hobbes]
     Full Idea: There can be no effect but from a sufficient and necessary cause.
     From: Thomas Hobbes (De Corpore (Elements, First Section) [1655], 2.10.02)
     A reaction: To be compared with Mackie's subtler modern account of this matter. If two different separate causes could lead to the same result, it is hard to see how the cause must be 'necessary' (unless you say they lead to different effects).
26. Natural Theory / C. Causation / 9. General Causation / d. Causal necessity
A cause is the complete sum of the features which necessitate the effect [Hobbes]
     Full Idea: A cause it the sum or aggregate of all such accidents, both in the agents and in the patient, as concur to the producing of the effect propounded; all of which existing together, ti cannot be understood but that the effect existenth without them.
     From: Thomas Hobbes (De Corpore (Elements, First Section) [1655], 1.6.10)
     A reaction: For most causes we meet, this definition will include gravity and electro-magnetism, so it doesn't help in narrowing things down. Notice that he accepts the necessity, despite his committed empiricism.
26. Natural Theory / D. Laws of Nature / 8. Scientific Essentialism / b. Scientific necessity
If the laws of nature are contingent, shouldn't we already have noticed it? [Meillassoux]
     Full Idea: The standard objection is that if the laws of nature were actually contingent, we would already have noticed it.
     From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 4)
     A reaction: Meillassoux offers a sustained argument that the laws of nature are necessarily contingent. In Idea 19660 he distinguishes contingencies that must change from those that merely could change.
Why are contingent laws of nature stable? [Meillassoux]
     Full Idea: We must ask how we are to explain the manifest stability of physical laws, given that we take these to be contingent?
     From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 4)
     A reaction: Meissalloux offers a very deep and subtle answer to this question... It is based on the possibilities of chaos being an uncountable infinity... It is a very nice question, which physicists might be able to answer, without help from philosophy.
27. Natural Reality / A. Classical Physics / 1. Mechanics / a. Explaining movement
Motion is losing one place and acquiring another [Hobbes]
     Full Idea: Motion is privation of one place, and the acquisition of another.
     From: Thomas Hobbes (De Corpore (Elements, First Section) [1655], 1.6.06)
     A reaction: This is basically the 'at-at' theory of motion which empiricists like, because it breaks motion down into atoms of experience. Hobbes needs an ontology which includes 'places'.
27. Natural Reality / A. Classical Physics / 1. Mechanics / c. Forces
'Force' is the quantity of movement imposed on something [Hobbes]
     Full Idea: I define 'force' to be the impetus or quickness of motion multiplied either into itself, or into the magnitude of the movent, by means of which whereof the said movent works more or less upon the body that resists it.
     From: Thomas Hobbes (De Corpore (Elements, First Section) [1655], 3.15.02)
     A reaction: Not very helpful, perhaps, but it shows a view of force at quite an early date, well before Newton.
27. Natural Reality / D. Time / 2. Passage of Time / k. Temporal truths
Past times can't exist anywhere, apart from in our memories [Hobbes]
     Full Idea: When people speak of the times of their predecessors, they do not think after their predecessors are gone that their times can be any where else than in the memory of those that remember.
     From: Thomas Hobbes (De Corpore (Elements, First Section) [1655], 2.07.03)
28. God / B. Proving God / 2. Proofs of Reason / a. Ontological Proof
The ontological proof of a necessary God ensures a reality external to the mind [Meillassoux]
     Full Idea: Since Descartes conceives of God as existing necessarily, whether I exist to think of him or not, Descartes assures me of a possible access to an absolute reality - a Great Outdoors that is not a correlate of my thought.
     From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 2)
     A reaction: His point is that the ontological argument should be seen as part of the scientific revolution, and not an anomaly within it. Interesting.
28. God / C. Attitudes to God / 5. Atheism
Now that the absolute is unthinkable, even atheism is just another religious belief (though nihilist) [Meillassoux]
     Full Idea: Once the absolute has become unthinkable, even atheism, which also targets God's inexistence in the manner of an absolute, is reduced to a mere belief, and hence to a religion, albeit of the nihilist kind.
     From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 2)
     A reaction: An interesting claim. Rather hard to agree or disagree, though the idea that atheism must qualify as a religion seems odd. If it is unqualified it does have the grand quality of a religion, but if it is fallibilist it just seems like an attitude.
