9. Objects / A. Existence of Objects / 5. Simples
The simple's whatness is its very self [Avicenna]
9. Objects / C. Structure of Objects / 3. Matter of an Object
The ultimate material of things has the unity of total formlessness [Avicenna]
9. Objects / D. Essence of Objects / 2. Types of Essence
An essence can either be universal (in the mind) or singular (in concrete particulars) [Avicenna, by Panaccio]
9. Objects / F. Identity among Objects / 7. Indiscernible Objects
The Indiscernibility of Identicals is a truism; but the Identity of Indiscernibles depends on possible identical worlds [Rey]
12. Knowledge Sources / A. A Priori Knowledge / 1. Nature of the A Priori
The traditional a priori is justified without experience; post-Quine it became unrevisable by experience [Rey]
12. Knowledge Sources / D. Empiricism / 1. Empiricism
Empiricism says experience is both origin and justification of all knowledge [Rey]
13. Knowledge Criteria / C. External Justification / 9. Naturalised Epistemology

Intentional explanations are always circular [Rey]
15. Nature of Minds / B. Features of Minds / 5. Qualia / a. Nature of qualia
Arithmetic and unconscious attitudes have no qualia [Rey]
Why qualia, and why this particular quale? [Rey]
15. Nature of Minds / B. Features of Minds / 5. Qualia / b. Qualia and intentionality
If qualia have no function, their attachment to thoughts is accidental [Rey]

Experiments prove that people are often unaware of their motives [Rey]
Brain damage makes the unreliability of introspection obvious [Rey]
16. Persons / F. Free Will / 5. Against Free Will
If reason could be explained in computational terms, there would be no need for the concept of 'free will' [Rey]
Free will isn't evidence against a theory of thought if there is no evidence for free will [Rey]
17. Mind and Body / B. Behaviourism / 1. Behaviourism
Maybe behaviourists should define mental states as a group [Rey]
Behaviourism is eliminative, or reductionist, or methodological [Rey]
17. Mind and Body / B. Behaviourism / 4. Behaviourism Critique
Animals don't just respond to stimuli, they experiment [Rey]
How are stimuli and responses 'similar'? [Rey]
Behaviour is too contingent and irrelevant to be the mind [Rey]
17. Mind and Body / C. Functionalism / 1. Functionalism
If a normal person lacked a brain, would you say they had no mind? [Rey]
Dualism and physicalism explain nothing, and don't suggest any research [Rey]
17. Mind and Body / C. Functionalism / 6. Homuncular Functionalism
Homuncular functionalism (e.g. Freud) could be based on simpler mechanical processes [Rey]
17. Mind and Body / C. Functionalism / 7. Chinese Room
Is the room functionally the same as a Chinese speaker? [Rey]
Searle is guilty of the fallacy of division - attributing a property of the whole to a part [Rey]
17. Mind and Body / C. Functionalism / 8. Functionalism critique
One computer program could either play chess or fight a war [Rey]
17. Mind and Body / E. Mind as Physical / 3. Eliminativism
If you explain water as H2O, you have reduced water, but not eliminated it [Rey]
Human behaviour can show law-like regularity, which eliminativism can't explain [Rey]
17. Mind and Body / E. Mind as Physical / 4. Connectionism
Pattern recognition is puzzling for computation, but makes sense for connectionism [Rey]
Connectionism explains well speed of perception and 'graceful degradation' [Rey]
Connectionism explains irrationality (such as the Gamblers' Fallacy) quite well [Rey]
Connectionism assigns numbers to nodes and branches, and plots the outcomes [Rey]
17. Mind and Body / E. Mind as Physical / 7. Anti-Physicalism / a. Physicalism critique
Can identity explain reason, free will, non-extension, intentionality, subjectivity, experience? [Rey]
Physicalism offers something called "complexity" instead of mental substance [Rey]
18. Thought / A. Modes of Thought / 2. Propositional Attitudes
Some attitudes are information (belief), others motivate (hatred) [Rey]
18. Thought / B. Mechanics of Thought / 3. Modularity of Mind
Children speak 90% good grammar [Rey]
Good grammar can't come simply from stimuli [Rey]
18. Thought / B. Mechanics of Thought / 4. Language of Thought
Animals may also use a language of thought [Rey]
We train children in truth, not in grammar [Rey]
18. Thought / B. Mechanics of Thought / 6. Artificial Thought / a. Artificial Intelligence

Anything bears a family resemblance to a game, but obviously not anything counts as one [Rey]
19. Language / A. Nature of Meaning / 5. Meaning as Verification
A one hour gap in time might be indirectly verified, but then almost anything could be [Rey]
19. Language / A. Nature of Meaning / 6. Meaning as Use
The meaning of "and" may be its use, but not of "animal" [Rey]
19. Language / A. Nature of Meaning / 7. Meaning Holism / b. Language holism
Semantic holism means new evidence for a belief changes the belief, and we can't agree on concepts [Rey]
19. Language / A. Nature of Meaning / 8. Synonymy
Externalist synonymy is there being a correct link to the same external phenomena [Rey]
19. Language / B. Reference / 3. Direct Reference / b. Causal reference
Causal theories of reference (by 'dubbing') don't eliminate meanings in the heads of dubbers [Rey]
If meaning and reference are based on causation, then virtually everything has meaning [Rey]
19. Language / B. Reference / 4. Descriptive Reference / a. Sense and reference
Referential Opacity says truth is lost when you substitute one referring term ('mother') for another ('Jocasta') [Rey]
19. Language / E. Analyticity / 1. Analytic Propositions
'Married' does not 'contain' its symmetry, nor 'bigger than' its transitivity [Rey]
Analytic judgements can't be explained by contradiction, since that is what is assumed [Rey]
Analytic statements are undeniable (because of meaning), rather than unrevisable [Rey]
The meaning properties of a term are those which explain how the term is typically used [Rey]
An intrinsic language faculty may fix what is meaningful (as well as grammatical) [Rey]
Research throws doubts on the claimed intuitions which support analyticity [Rey]
19. Language / E. Analyticity / 4. Analytic/Synthetic Critique
If we claim direct insight to what is analytic, how do we know it is not sub-consciously empirical? [Rey]
19. Language / F. Communication / 5. Pragmatics / b. Implicature
A simple chaining device can't build sentences containing 'either..or', or 'if..then' [Rey]
23. Ethics / C. Virtue Theory / 2. Elements of Virtue Theory / h. Right feelings
Our desires become important when we have desires about desires [Rey]
26. Natural Theory / A. Speculations on Nature / 5. Infinite in Nature
There are probably no infinities, and 'infinite' names what we do not yet know [Rovelli]
26. Natural Theory / A. Speculations on Nature / 6. Early Matter Theories / d. The unlimited
The basic ideas of fields and particles are merged in quantum mechanics [Rovelli]
27. Natural Reality / B. Modern Physics / 2. Electrodynamics / b. Fields

There are about fifteen particles fields, plus a few force fields [Rovelli]
The world consists of quantum fields, with elementary events happening in spacetime [Rovelli]
27. Natural Reality / B. Modern Physics / 2. Electrodynamics / c. Electrons
Electrons only exist when they interact, and their being is their combination of quantum leaps [Rovelli]
Electrons are not waves, because their collisions are at a point, and not spread out [Rovelli]
27. Natural Reality / B. Modern Physics / 2. Electrodynamics / d. Quantum mechanics
Quantum Theory describes events and possible interactions - not how things are [Rovelli]
27. Natural Reality / B. Modern Physics / 4. Standard Model / a. Concept of matter
Nature has three aspects: granularity, indeterminacy, and relations [Rovelli]
27. Natural Reality / C. Space / 4. Substantival Space
