17. Mind and Body / D. Property Dualism / 3. Property Dualism
Why bother with neurons? You don't explain bird flight by examining feathers [Fodor]
Are beliefs brains states, but picked out at a "higher level"? [Lyons on Fodor]
17. Mind and Body / D. Property Dualism / 5. Supervenience of mind
Even if tightly united, mind and body are different, as God could separate them [Descartes]
Supervenience gives good support for mental causation [Fodor]
17. Mind and Body / E. Mind as Physical / 1. Physical Mind
Type physicalism equates mental kinds with physical kinds [Fodor]
Type physicalism is a stronger claim than token physicalism [Fodor]
17. Mind and Body / E. Mind as Physical / 4. Connectionism
Modern connectionism is just Hume's theory of the 'association' of 'ideas' [Fodor]
Only the labels of nodes have semantic content in connectionism, and they play no role [Fodor]
Hume has no theory of the co-ordination of the mind [Fodor]
Hume's associationism offers no explanation at all of rational thought [Fodor]
17. Mind and Body / E. Mind as Physical / 6. Conceptual Dualism
The concept of mind excludes body, and vice versa [Descartes]
17. Mind and Body / E. Mind as Physical / 7. Anti-Physicalism / a. Physicalism critique
If mind is just physical, how can it follow the rules required for intelligent thought? [Fodor]
17. Mind and Body / E. Mind as Physical / 7. Anti-Physicalism / b. Multiple realisability
Lots of physical properties are multiply realisable, so why shouldn't beliefs be? [Fodor]
Most psychological properties seem to be multiply realisable [Fodor]
18. Thought / A. Modes of Thought / 1. Thought
The goal of thought is to understand the world, not instantly sort it into conceptual categories [Fodor]
Associative thinking avoids syntax, but can't preserve sense, reference or truth [Fodor]
We may be able to explain rationality mechanically [Fodor]
Connectionism gives no account of how constituents make complex concepts [Fodor]
18. Thought / A. Modes of Thought / 2. Propositional Attitudes
In some thoughts I grasp a subject, but also I will or fear or affirm or deny it [Descartes]
Propositional attitudes are propositions presented in a certain way [Fodor]
18. Thought / A. Modes of Thought / 3. Emotions / c. Role of emotions
For Descartes passions are God-given preservers of the mind-body union [Descartes, by Taylor,C]
18. Thought / A. Modes of Thought / 3. Emotions / e. Basic emotions
Are there a few primary passions (say, joy, sadness and desire)? [Descartes, by Cottingham]
There are six primitive passions: wonder, love, hatred, desire, joy and sadness [Descartes, by Goldie]
18. Thought / A. Modes of Thought / 4. Folk Psychology
Folk psychology is the only explanation of behaviour we have [Fodor]
Folk psychology explains behaviour by reference to intentional states like belief and desire [Fodor]
18. Thought / A. Modes of Thought / 5. Rationality / a. Rationality
Rationality has mental properties - autonomy, productivity, experiment [Fodor]
18. Thought / A. Modes of Thought / 5. Rationality / b. Human rationality
Descartes created the modern view of rationality, as an internal feature instead of an external vision [Descartes, by Taylor,C]
18. Thought / A. Modes of Thought / 6. Judgement / b. Error
I make errors because my will extends beyond my understanding [Descartes]
Most errors of judgement result from an inaccurate perception of the facts [Descartes]
18. Thought / B. Mechanics of Thought / 3. Modularity of Mind
Blindness doesn't destroy spatial concepts [Fodor]
Something must take an overview of the modules [Fodor]
Modules have in-built specialist information [Fodor]
Mental modules are specialised, automatic, and isolated [Fodor, by Okasha]
Modules have encapsulation, inaccessibility, private concepts, innateness [Fodor]
Obvious modules are language and commonsense explanation [Fodor]
Modules analyse stimuli, they don't tell you what to do [Fodor]
Modules make the world manageable [Fodor]
Babies talk in consistent patterns [Fodor]
Rationality rises above modules [Fodor]
18. Thought / B. Mechanics of Thought / 4. Language of Thought
Language is ambiguous, but thought isn't [Fodor]
Mentalese may also incorporate some natural language [Fodor]
Mentalese doesn't require a theory of meaning [Fodor]
Belief and desire are structured states, which need mentalese [Fodor]
Ambiguities in English are the classic reason for claiming that we don't think in English [Fodor]
Since the language of thought is the same for all, it must be something like logical form [Fodor, by Devlin]
We must have expressive power BEFORE we learn language [Fodor]
18. Thought / B. Mechanics of Thought / 5. Mental Files
Mental representations name things in the world, but also files in our memory [Fodor]
We think in file names [Fodor]
18. Thought / B. Mechanics of Thought / 6. Artificial Thought / a. Artificial Intelligence
Is thought a syntactic computation using representations? [Fodor, by Rey]
Frame Problem: how to eliminate most beliefs as irrelevant, without searching them? [Fodor]
18. Thought / B. Mechanics of Thought / 6. Artificial Thought / c. Turing Test
A machine could speak in response to physical stimulus, but not hold a conversation [Descartes]
18. Thought / C. Content / 1. Content
Maybe narrow content is physical, broad content less so [Lyons on Fodor]
18. Thought / C. Content / 2. Ideas
True ideas are images, such as of a man, a chimera, or God [Descartes]
Mental representations are the old 'Ideas', but without images [Fodor]
18. Thought / C. Content / 5. Twin Earth
XYZ (Twin Earth 'water') is an impossibility [Fodor]
If concept content is reference, then my Twin and I are referring to the same stuff [Fodor]
18. Thought / C. Content / 6. Broad Content
Truth conditions require a broad concept of content [Fodor]
How could the extrinsic properties of thoughts supervene on their intrinsic properties? [Fodor]
18. Thought / C. Content / 7. Narrow Content
Obsession with narrow content leads to various sorts of hopeless anti-realism [Fodor]
Concepts aren't linked to stuff; they are what is caused by stuff [Fodor]
18. Thought / C. Content / 9. Conceptual Role Semantics
Content can't be causal role, because causal role is decided by content [Fodor]
18. Thought / C. Content / 10. Causal Semantics
All ideas are adventitious, and come from the senses [Gassendi on Descartes]
Do identical thoughts have identical causal roles? [Fodor]
Knowing the cause of a thought is almost knowing its content [Fodor]
18. Thought / C. Content / 12. Informational Semantics
Is content basically information, fixed externally? [Fodor]
18. Thought / D. Concepts / 2. Origin of Concepts / a. Origin of concepts
Nobody knows how concepts are acquired [Fodor]
18. Thought / D. Concepts / 2. Origin of Concepts / c. Nativist concepts
The ideas of God and of my self are innate in me [Descartes]
I can think of innumerable shapes I have never experienced [Descartes]
Qualia must be innate, because physical motions do not contain them [Descartes]
Experience can't explain itself; the concepts needed must originate outside experience [Fodor]
If concept-learning is hypothesis-testing, that needs innate concepts to get started [Fodor, by Margolis/Laurence]
Fodor is now less keen on the innateness of concepts [Fodor, by Lowe]
We have an innate capacity to form a concept, once we have grasped the stereotype [Fodor]
A blind man may still contain the idea of colour [Descartes]
The mind's innate ideas are part of its capacity for thought [Descartes]
The idea of a supremely perfect being is within me, like the basic concepts of mathematics [Descartes]
18. Thought / D. Concepts / 3. Ontology of Concepts / a. Concepts as representations
It is essential to the concept CAT that it be satisfied by cats [Fodor]
Having a concept isn't a pragmatic matter, but being able to think about the concept [Fodor]
Concepts have two sides; they are files that face thought, and also face subject-matter [Fodor]
18. Thought / D. Concepts / 3. Ontology of Concepts / b. Concepts as abilities
Cartesians put concept individuation before concept possession [Fodor]
In the information view, concepts are potentials for making distinctions [Fodor]
I prefer psychological atomism - that concepts are independent of epistemic capacities [Fodor]
Are concepts best seen as capacities? [Fodor]
For Pragmatists having a concept means being able to do something [Fodor]
18. Thought / D. Concepts / 3. Ontology of Concepts / c. Fregean concepts
Frege's puzzles suggest to many that concepts have sense as well as reference [Fodor]
If concepts have sense, we can't see the connection to their causal powers [Fodor]
Belief in 'senses' may explain intentionality, but not mental processes [Fodor]
18. Thought / D. Concepts / 4. Structure of Concepts / a. Conceptual structure
You can't think 'brown dog' without thinking 'brown' and 'dog' [Fodor]
18. Thought / D. Concepts / 4. Structure of Concepts / b. Analysis of concepts
Definable concepts have constituents, which are necessary, individuate them, and demonstrate possession [Fodor]
18. Thought / D. Concepts / 4. Structure of Concepts / d. Concepts as prototypes
Many concepts lack prototypes, and complex prototypes aren't built from simple ones [Fodor]
Maybe stereotypes are a stage in concept acquisition (rather than a by-product) [Fodor]
One stereotype might be a paradigm for two difference concepts [Fodor]
18. Thought / D. Concepts / 4. Structure of Concepts / f. Theory theory of concepts
The theory theory can't actually tell us what concepts are [Fodor]
18. Thought / D. Concepts / 4. Structure of Concepts / g. Conceptual atomism
For the referential view of thought, the content of a concept is just its reference [Fodor]
Compositionality requires that concepts be atomic [Fodor]
18. Thought / E. Abstraction / 2. Abstracta by Selection
Abstractionism claims that instances provide criteria for what is shared [Fodor]
19. Language / A. Nature of Meaning / 1. Meaning
Semantic externalism says the concept 'elm' needs no further beliefs or inferences [Fodor]
If meaning is information, that establishes the causal link between the state of the world and our beliefs [Fodor]
19. Language / A. Nature of Meaning / 3. Meaning as Speaker's Intention
Grice thinks meaning is inherited from the propositional attitudes which sentences express [Fodor]
It seems unlikely that meaning can be reduced to communicative intentions, or any mental states [Fodor]
19. Language / A. Nature of Meaning / 4. Meaning as Truth-Conditions
Whatever in the mind delivers falsehood is parasitic on what delivers truth [Fodor]
To know the content of a thought is to know what would make it true [Fodor]
19. Language / A. Nature of Meaning / 5. Meaning as Verification
Many different verification procedures can reach 'star', but it only has one semantic value [Fodor]
19. Language / A. Nature of Meaning / 6. Meaning as Use
The meaning of a sentence derives from its use in expressing an attitude [Fodor]
19. Language / A. Nature of Meaning / 7. Meaning Holism / b. Language holism
Meaning holism is a crazy doctrine [Fodor]
For holists no two thoughts are ever quite the same, which destroys faith in meaning [Fodor]
If to understand "fish" you must know facts about them, where does that end? [Fodor]
19. Language / A. Nature of Meaning / 7. Meaning Holism / c. Meaning by Role
Very different mental states can share their contents, so content doesn't seem to be constructed from functional role [Fodor]
'Inferential-role semantics' says meaning is determined by role in inference [Fodor]
19. Language / A. Nature of Meaning / 8. Synonymy
Mental states may have the same content but different extensions [Fodor]
19. Language / B. Reference / 1. Reference theories
Co-referring terms differ if they have different causal powers [Fodor]
We refer to individuals and to properties, and we use singular terms and predicates [Fodor]
19. Language / B. Reference / 4. Descriptive Reference / a. Sense and reference
It is claimed that reference doesn't fix sense (Jocasta), and sense doesn't fix reference (Twin Earth) [Fodor]
19. Language / C. Assigning Meanings / 2. Semantics
Broad semantics holds that the basic semantic properties are truth and denotation [Fodor]
English has no semantic theory, just associations between sentences and thoughts [Fodor]
Semantics (esp. referential semantics) allows inferences from utterances to the world [Fodor]
Semantics relates to the world, so it is never just psychological [Fodor]
19. Language / C. Assigning Meanings / 6. Truth-Conditions Semantics
Externalist semantics are necessary to connect the contents of beliefs with how the world is [Fodor]
19. Language / E. Analyticity / 3. Analytic and Synthetic
Analysis is impossible without the analytic/synthetic distinction [Fodor]
19. Language / F. Communication / 4. Private Language
The theory of the content of thought as 'Mentalese' explains why the Private Language Argument doesn't work [Fodor]
20. Action / B. Preliminaries of Action / 2. Willed Action / b. Volitionism
Merely willing to walk leads to our walking [Descartes]
20. Action / C. Motives for Action / 3. Acting on Reason / a. Practical reason
Before you can plan action, you must decide on the truth of your estimate of success [Fodor]
20. Action / C. Motives for Action / 4. Responsibility for Actions
We do not praise the acts of an efficient automaton, as their acts are necessary [Descartes]
The greatest perfection of man is to act by free will, and thus merit praise or blame [Descartes]
22. Metaethics / B. Value / 2. Values / e. Death
We don't die because the soul departs; the soul departs because the organs cease functioning [Descartes]
23. Ethics / C. Virtue Theory / 1. Virtue Theory / d. Virtue theory critique
Greeks elevate virtues enormously, but never explain them [Descartes]
23. Ethics / C. Virtue Theory / 3. Virtues / a. Virtues
Descartes makes strength of will the central virtue [Descartes, by Taylor,C]

Essence must be known before we discuss existence [Descartes]
24. Political Theory / D. Ideologies / 11. Capitalism
We are currently extending capitalism to the whole of society [Deleuze]
25. Social Practice / A. Freedoms / 2. Freedom of belief
Some lines (of flight) are becomings which escape the system [Deleuze]
25. Social Practice / E. Policies / 1. War / a. Just wars
The State requires self-preservation, but the war-machine desires destruction [Deleuze]
26. Natural Theory / A. Speculations on Nature / 1. Nature
Nature is devoid of thought [Descartes, by Meillassoux]
Physics only needs geometry or abstract mathematics, which can explain and demonstrate everything [Descartes]
26. Natural Theory / A. Speculations on Nature / 2. Natural Purpose / a. Final purpose
Many causes are quite baffling, so it is absurd to deduce causes from final purposes [Descartes]
26. Natural Theory / A. Speculations on Nature / 2. Natural Purpose / c. Purpose denied
We will not try to understand natural or divine ends, or final causes [Descartes]
26. Natural Theory / A. Speculations on Nature / 4. Mathematical Nature
All the sciences searching for order and measure are related to mathematics [Descartes]
26. Natural Theory / A. Speculations on Nature / 6. Early Matter Theories / f. Ancient elements
The Hot, Cold, Wet and Dry of the philosophers need themselves to be explained [Descartes]
26. Natural Theory / A. Speculations on Nature / 7. Later Matter Theories / c. Matter as extension
Impenetrability only belongs to the essence of extension [Descartes]
Matter can't just be Descartes's geometry, because a filler of the spaces is needed [Robinson,H on Descartes]
Matter is not hard, heavy or coloured, but merely extended in space [Descartes]
26. Natural Theory / C. Causation / 8. Particular Causation / c. Conditions of causation
There must be at least as much in the cause as there is in the effect [Descartes]
26. Natural Theory / D. Laws of Nature / 7. Strictness of Laws
God has established laws throughout nature, and implanted ideas of them within us [Descartes]
26. Natural Theory / D. Laws of Nature / 9. Counterfactual Claims
Laws are true generalisations which support counterfactuals and are confirmed by instances [Fodor]
27. Natural Reality / A. Classical Physics / 1. Mechanics / b. Laws of motion
Descartes said there was conservation of 'quantity of motion' [Descartes, by Papineau]
28. God / A. Divine Nature / 2. Divine Nature
God the creator is an intelligent, infinite, powerful substance [Descartes]
Nothing apart from God could have essential existence, and such a being must be unique and eternal [Descartes]
28. God / A. Divine Nature / 3. Divine Perfections
It is self-evident that deception is a natural defect, so God could not be a deceiver [Descartes]
28. God / A. Divine Nature / 6. Divine Morality / d. God decrees morality
Ideas in God's mind only have value if he makes it so [Descartes]
28. God / B. Proving God / 2. Proofs of Reason / a. Ontological Proof
Existence and God's essence are inseparable, like a valley and a mountain, or a triangle and its properties [Descartes]
The idea of God in my mind is like the mark a craftsman puts on his work [Descartes]
Necessary existence is a property which is uniquely part of God's essence [Descartes]
One idea leads to another, but there must be an initial idea that contains the reality of all the others [Descartes]
Possible existence is a perfection in the idea of a triangle [Descartes]
I cannot think of a supremely perfect being without the supreme perfection of existence [Descartes]
28. God / B. Proving God / 2. Proofs of Reason / b. Ontological Proof critique
We mustn't worship God as an image because we have no idea of him [Hobbes on Descartes]
We can never conceive of an infinite being [Gassendi on Descartes]
Descartes cannot assume that a most perfect being exists without contradictions [Leibniz on Descartes]
Existence is not a perfection; it is what makes perfection possible [Gassendi on Descartes]
28. God / B. Proving God / 3. Proofs of Evidence / a. Cosmological Proof
We can't prove a first cause from our inability to grasp infinity [Descartes]
28. God / C. Attitudes to God / 5. Atheism
Atheism is an atrocious and intolerable crime in any country [Descartes]
Atheism arises from empiricism, because God is intangible [Descartes]
29. Religion / B. Monotheistic Religion / 4. Christianity / c. Angels
An angelic mind would not experience pain, even when connected to a human body [Descartes, by Pasnau]
29. Religion / D. Religious Issues / 2. Immortality / b. Soul
I can't prove the soul is indestructible, only that it is separate from the mortal body [Descartes]
29. Religion / D. Religious Issues / 3. Problem of Evil / c. Human Error
God didn't give us good judgement even about our own lives [Gassendi on Descartes]
Error arises because my faculty for judging truth is not infinite [Descartes]
Since God does not wish to deceive me, my judgement won't make errors if I use it properly [Descartes]
29. Religion / D. Religious Issues / 3. Problem of Evil / d. Natural Evil
If we ask whether God's works are perfect, we must not take a narrow viewpoint, but look at the universe as a whole [Descartes]
