2. Reason / D. Definition / 8. Impredicative Definition
21704 'Impredictative' definitions fix a class in terms of the greater class to which it belongs [Linsky,B]
4. Formal Logic / F. Set Theory ST / 4. Axioms for Sets / p. Axiom of Reducibility
21705 Reducibility says any impredicative function has an appropriate predicative replacement [Linsky,B]
5. Theory of Logic / F. Referring in Logic / 2. Descriptions / c. Theory of definite descriptions
21727 Definite descriptions theory eliminates the King of France, but not the Queen of England [Linsky,B]
5. Theory of Logic / I. Semantics of Logic / 5. Extensionalism
21719 Extensionalism means what is true of a function is true of coextensive functions [Linsky,B]
6. Mathematics / C. Sources of Mathematics / 6. Logicism / a. Early logicism
21723 The task of logicism was to define by logic the concepts 'number', 'successor' and '0' [Linsky,B]
6. Mathematics / C. Sources of Mathematics / 6. Logicism / b. Type theory
21721 Higher types are needed to distinguished intensional phenomena which are coextensive [Linsky,B]
21703 Types are 'ramified' when there are further differences between the type of quantifier and its range [Linsky,B]
21714 The ramified theory subdivides each type, according to the range of the variables [Linsky,B]
6. Mathematics / C. Sources of Mathematics / 6. Logicism / d. Logicism critique
21713 Did logicism fail, when Russell added three nonlogical axioms, to save mathematics? [Linsky,B]
21715 For those who abandon logicism, standard set theory is a rival option [Linsky,B]
7. Existence / D. Theories of Reality / 5. Naturalism
3509 Externalism may be the key idea in philosophical naturalism [Papineau]
8. Modes of Existence / B. Properties / 11. Properties as Sets
21729 Construct properties as sets of objects, or say an object must be in the set to have the property [Linsky,B]
17. Mind and Body / A. Mind-Body Dualism / 8. Dualism of Mind Critique
3513 How does a dualist mind represent, exist outside space, and be transparent to itself? [Papineau]
17. Mind and Body / C. Functionalism / 8. Functionalism critique
3514 Functionalism needs causation and intentionality to explain actions [Papineau]
17. Mind and Body / D. Property Dualism / 5. Supervenience of mind
3510 Epiphenomenalism is supervenience without physicalism [Papineau]
3511 Supervenience requires all mental events to have physical effects [Papineau]
17. Mind and Body / E. Mind as Physical / 1. Physical Mind
3515 Knowing what it is like to be something only involves being (physically) that thing [Papineau]
17. Mind and Body / E. Mind as Physical / 7. Anti-Physicalism / b. Multiple realisability
3512 If a mental state is multiply realisable, why does it lead to similar behaviour? [Papineau]
19. Language / F. Communication / 4. Private Language
3516 The Private Language argument only means people may misjudge their experiences [Papineau]
27. Natural Reality / A. Classical Physics / 1. Mechanics / c. Forces
12719 Clearly, force is that from which action follows, when unimpeded [Leibniz]
27. Natural Reality / D. Time / 1. Nature of Time / i. Denying time
12720 Time doesn't exist, since its parts don't coexist [Leibniz]
