101 ideas

1. Philosophy / F. Analytic Philosophy / 7. Limitations of Analysis
Analytic philosophy focuses too much on forms of expression, instead of what is actually said [Tait]
4. Formal Logic / F. Set Theory ST / 3. Types of Set / b. Empty (Null) Set
The null set was doubted, because numbering seemed to require 'units' [Tait]
4. Formal Logic / F. Set Theory ST / 7. Natural Sets
We can have a series with identical members [Tait]
5. Theory of Logic / F. Referring in Logic / 1. Naming / d. Singular terms
Varieties of singular terms are used to designate token particulars [Rey]
5. Theory of Logic / K. Features of Logics / 1. Axiomatisation
Mathematics must be based on axioms, which are true because they are axioms, not vice versa [Tait, by Parsons,C]
6. Mathematics / C. Sources of Mathematics / 4. Mathematical Empiricism / b. Indispensability of mathematics
Physics requires the existence of properties, and also the abstract objects of arithmetic [Rey]
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
Animal learning is separate from their behaviour [Rey]
14. Science / D. Explanation / 3. Best Explanation / a. Best explanation
Abduction could have true data and a false conclusion, and may include data not originally mentioned [Rey]
14. Science / D. Explanation / 3. Best Explanation / b. Ultimate explanation
It's not at all clear that explanation needs to stop anywhere [Rey]

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]

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
Free will isn't evidence against a theory of thought if there is no evidence for free will [Rey]
If reason could be explained in computational terms, there would be no need for the concept of '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

If you explain water as H2O, you have reduced water, but not eliminated it [Rey]
17. Mind and Body / E. Mind as Physical / 4. Connectionism
Connectionism assigns numbers to nodes and branches, and plots the outcomes [Rey]
Connectionism explains well speed of perception and 'graceful degradation' [Rey]
Connectionism explains irrationality (such as the Gamblers' Fallacy) quite well [Rey]
Pattern recognition is puzzling for computation, but makes sense for connectionism [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]

Anything bears a family resemblance to a game, but obviously not anything counts as one [Rey]
18. Thought / E. Abstraction / 2. Abstracta by Selection
Abstraction is 'logical' if the sense and truth of the abstraction depend on the concrete [Tait]
Cantor and Dedekind use abstraction to fix grammar and objects, not to carry out proofs [Tait]
18. Thought / E. Abstraction / 7. Abstracta by Equivalence
Abstraction may concern the individuation of the set itself, not its elements [Tait]
18. Thought / E. Abstraction / 8. Abstractionism Critique
Why should abstraction from two equipollent sets lead to the same set of 'pure units'? [Tait]
If abstraction produces power sets, their identity should imply identity of the originals [Tait]

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]

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
Analytic judgements can't be explained by contradiction, since that is what is assumed [Rey]
'Married' does not 'contain' its symmetry, nor 'bigger than' its transitivity [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]

Wars can be unjust, despite a just cause, if they are unnecessary or excessive or of mixed cause [McMahan]
A person or state may be attacked if they are responsible for an unjustified threat [McMahan]
The worst unjustified wars have no aim at all [McMahan]
Just war theory says all and only persons posing a threat are liable to attack [McMahan]
You (e.g. a police officer) are not liable to attack just because you pose a threat [McMahan]
A defensive war is unjust, if it is responding to a just war [McMahan]
25. Social Practice / E. Policies / 1. War / b. Justice in war
Proportionality in fighting can't be judged independently of the justice of each side [McMahan]
Can an army start an unjust war, and then fight justly to defend their own civilians? [McMahan]
Soldiers cannot freely fight in unjust wars, just because they behave well when fighting [McMahan]
The law of war differs from criminal law; attacking just combatants is immoral, but legal [McMahan]
If the unjust combatants are morally excused they are innocent, so how can they be killed? [McMahan]
25. Social Practice / E. Policies / 1. War / c. Combatants
If all combatants are seen as morally equal, that facilitates starting unjust wars [McMahan]
You don't become a legitimate target, just because you violently resist an unjust attack [McMahan]
Volunteer soldiers accept the risk of attack, but they don't agree to it, or to their deaths [McMahan]
Soldiers cannot know enough facts to evaluate the justice of their war [McMahan]
If being part of a big collective relieves soldiers of moral responsibility, why not the leaders too? [McMahan]
If soldiers can't refuse to fight in unjust wars, can they choose to fight in just wars? [McMahan]
Equality is both sides have permission, or both sides are justified, or one justified the other permitted [McMahan]
Fighting unjustly under duress does not justify it, or permit it, but it may excuse it [McMahan]
25. Social Practice / E. Policies / 1. War / d. Non-combatants
Innocence implies not being morally responsible, rather than merely being guiltless [McMahan]
25. Social Practice / E. Policies / 1. War / e. Peace
Unconditional surrender can't be demanded, since evil losers still have legitimate conditions [McMahan]
