1. Philosophy / D. Nature of Philosophy / 3. Philosophy Defined
Traditionally philosophy is an a priori enquiry into general truths about reality
Most of philosophy begins where science leaves off
6. Mathematics / C. Sources of Mathematics / 1. Mathematical Platonism / b. Against mathematical platonism
'Real' maths objects have no causal role, no determinate reference, and no abstract/concrete distinction
12. Knowledge Sources / A. A Priori Knowledge / 8. A Priori as Analytic
Frege tried to explain synthetic a priori truths by expanding the concept of analyticity
12. Knowledge Sources / D. Empiricism / 5. Empiricism Critique
Experience cannot teach us why maths and logic are necessary
19. Language / B. Meaning / 1. Meaning
Structuralists see meaning behaviouristically, and Chomsky says nothing about it
Sense determines meaning and synonymy, not referential properties like denotation and truth
19. Language / D. Theories of Reference / 4. Descriptive Reference / a. Sense and reference
It is generally accepted that sense is defined as the determiner of reference
19. Language / E. Propositions / 2. Nature of Propositions
Sentences are abstract types (like musical scores), not individual tokens
19. Language / F. Analytic/Synthetic / 2. Analytic Propositions
We don't have a clear enough sense of meaning to pronounce some sentences meaningless or just analytic
19. Language / F. Analytic/Synthetic / 4. Analytic/Synthetic Critique
Frege fails to give a concept of analyticity, so he fails to explain synthetic a priori truth that way
