Participation in an experiment requires agreement about what the outcome will mean [Fodor]
We can deliberately cause ourselves to have true thoughts - hence the value of experiments [Fodor]
Interrogation and experiment submit us to having beliefs caused [Fodor]
An experiment is a deliberate version of what informal thinking does all the time [Fodor]

If I have a set of mental modules, someone had better be in charge of them! [Fodor]
16. Persons / F. Free Will / 5. Against Free Will
Those actions that follow immediately the last appetite are voluntary [Hobbes]
Freedom is absence of opposition to action; the idea of 'free will' is absurd [Hobbes]
A man cannot will to will, or will to will to will, so the idea of a voluntary will is absurd [Hobbes]
If a man suddenly develops an intention of doing something, the cause is out of his control, not in his will [Hobbes]
16. Persons / F. Free Will / 7. Compatibilism
Liberty and necessity are consistent, as when water freely flows, by necessity [Hobbes]

17. Mind and Body / D. Property Dualism / 5. Supervenience of mind
Supervenience gives good support for mental causation [Fodor]
17. Mind and Body / E. Mind as Physical / 1. Physical Mind
Sensation is merely internal motion of the sentient being [Hobbes]
Type physicalism equates mental kinds with physical kinds [Fodor]
Type physicalism is a stronger claim than token physicalism [Fodor]
Conceptions and apparitions are just motion in some internal substance of the head [Hobbes]
17. Mind and Body / E. Mind as Physical / 4. Connectionism
Hume's associationism offers no explanation at all of rational thought [Fodor]
Hume has no theory of the co-ordination of the mind [Fodor]
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]

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

Most psychological properties seem to be multiply realisable [Fodor]
18. Thought / A. Modes of Thought / 1. Thought
We may be able to explain rationality mechanically [Fodor]
The goal of thought is to understand the world, not instantly sort it into conceptual categories [Fodor]
Connectionism gives no account of how constituents make complex concepts [Fodor]

18. Thought / B. Mechanics of Thought / 3. Modularity of Mind
Babies talk in consistent patterns [Fodor]
Rationality rises above modules [Fodor]
Mental modules are specialised, automatic, and isolated [Fodor, by Okasha]

Something must take an overview of the modules [Fodor]
Obvious modules are language and commonsense explanation [Fodor]
Blindness doesn't destroy spatial concepts [Fodor]
Modules have in-built specialist information [Fodor]
Modules analyse stimuli, they don't tell you what to do [Fodor]
Modules make the world manageable [Fodor]
18. Thought / B. Mechanics of Thought / 4. Language of Thought
Language is ambiguous, but thought isn't [Fodor]
Ambiguities in English are the classic reason for claiming that we don't think in English [Fodor]
Belief and desire are structured states, which need mentalese [Fodor]
Since the language of thought is the same for all, it must be something like logical form [Fodor, by Devlin]
Mentalese doesn't require a theory of meaning [Fodor]
We must have expressive power BEFORE we learn language [Fodor]
Mentalese may also incorporate some natural language [Fodor]
18. Thought / B. Mechanics of Thought / 5. Mental Files
Words are not for communication, but as marks for remembering what we have learned [Hobbes]

How could the extrinsic properties of thoughts supervene on their intrinsic properties? [Fodor]
Truth conditions require a broad concept of content [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
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

Nobody knows how concepts are acquired [Fodor]
18. Thought / D. Concepts / 2. Origin of Concepts / c. Nativist concepts
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]
Experience can't explain itself; the concepts needed must originate outside experience [Fodor]
We have an innate capacity to form a concept, once we have grasped the stereotype [Fodor]
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
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]
Cartesians put concept individuation before concept possession [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]
18. Thought / E. Abstraction / 7. Abstracta by Equivalence
I prefer the open sentences of a Constructibility Theory, to Platonist ideas of 'equivalence classes' [Chihara]
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 / 3. Direct Reference / b. Causal reference
Mathematical entities are causally inert, so the causal theory of reference won't work for them [Chihara]
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 / C. Motives for Action / 1. Acting on Desires
The will is just the last appetite before action [Hobbes]
It is an error that reason should control the passions, which give right guidance on their own [Hobbes, by Tuck]
