2. Reason / D. Definition / 4. Real Definition
9376 A sentence may simultaneously define a term, and also assert a fact [Boghossian]
3. Truth / H. Deflationary Truth / 3. Minimalist Truth
6345 Minimalism is incoherent, as it implies that truth both is and is not a property [Boghossian, by Horwich]
5. Theory of Logic / I. Semantics of Logic / 2. Formal Truth
9375 Conventionalism agrees with realists that logic has truth values, but not over the source [Boghossian]

9369 'Snow is white or it isn't' is just true, not made true by stipulation [Boghossian]
12. Knowledge Sources / A. A Priori Knowledge / 8. A Priori as Analytic
9367 The a priori is explained as analytic to avoid a dubious faculty of intuition [Boghossian]
9373 That logic is a priori because it is analytic resulted from explaining the meaning of logical constants [Boghossian]
9380 We can't hold a sentence true without evidence if we can't agree which sentence is definitive of it [Boghossian]
12. Knowledge Sources / A. A Priori Knowledge / 11. Denying the A Priori
9384 We may have strong a priori beliefs which we pragmatically drop from our best theory [Boghossian]
12. Knowledge Sources / E. Direct Knowledge / 2. Intuition
9374 If we learn geometry by intuition, how could this faculty have misled us for so long? [Boghossian]
13. Knowledge Criteria / A. Justification Problems / 2. Justification Challenges / a. Agrippa's trilemma

9372 Could expressions have meaning, without two expressions possibly meaning the same? [Boghossian]
19. Language / E. Analyticity / 2. Analytic Truths
17721 There are no truths in virtue of meaning, but there is knowability in virtue of understanding [Boghossian, by Jenkins]
19. Language / E. Analyticity / 3. Analytic and Synthetic
9368 Epistemological analyticity: grasp of meaning is justification; metaphysical: truth depends on meaning [Boghossian]
