2. Reason / D. Definition / 3. Types of Definition
13838 A decent modern definition should always imply a semantics [Hacking]
4. Formal Logic / B. Propositional Logic PL / 2. Tools of Propositional Logic / d. Basic theorems of PL
13833 'Thinning' ('dilution') is the key difference between deduction (which allows it) and induction [Hacking]
13834 Gentzen's Cut Rule (or transitivity of deduction) is 'If A |- B and B |- C, then A |- C' [Hacking]
13835 Only Cut reduces complexity, so logic is constructive without it, and it can be dispensed with [Hacking]
5. Theory of Logic / A. Overview of Logic / 4. Pure Logic
13845 The various logics are abstractions made from terms like 'if...then' in English [Hacking]
5. Theory of Logic / A. Overview of Logic / 5. First-Order Logic
13840 First-order logic is the strongest complete compact theory with Löwenheim-Skolem [Hacking]
13844 A limitation of first-order logic is that it cannot handle branching quantifiers [Hacking]
5. Theory of Logic / A. Overview of Logic / 7. Second-Order Logic
13842 Second-order completeness seems to need intensional entities and possible worlds [Hacking]
5. Theory of Logic / E. Structures of Logic / 2. Logical Connectives / a. Logical connectives
13837 With a pure notion of truth and consequence, the meanings of connectives are fixed syntactically [Hacking]
5. Theory of Logic / E. Structures of Logic / 4. Variables in Logic
13839 Perhaps variables could be dispensed with, by arrows joining places in the scope of quantifiers [Hacking]
5. Theory of Logic / J. Model Theory in Logic / 3. Löwenheim-Skolem Theorems
13843 If it is a logic, the Löwenheim-Skolem theorem holds for it [Hacking]
11. Knowledge Aims / A. Knowledge / 7. Knowledge First
19528 Knowledge is prior to believing, just as doing is prior to trying to do [Williamson]
19527 We don't acquire evidence and then derive some knowledge, because evidence IS knowledge [Williamson]
19529 Belief explains justification, and knowledge explains belief, so knowledge explains justification [Williamson]
19536 Knowledge-first says your total evidence IS your knowledge [Williamson]
19530 A neutral state of experience, between error and knowledge, is not basic; the successful state is basic [Williamson]
19531 Internalism about mind is an obsolete view, and knowledge-first epistemology develops externalism [Williamson]
11. Knowledge Aims / C. Knowing Reality / 1. Perceptual Realism / b. Direct realism
19526 Surely I am acquainted with physical objects, not with appearances? [Williamson]
13. Knowledge Criteria / C. External Justification / 6. Contextual Justification / a. Contextualism
19508 Contextualism needs a semantics for knowledge sentences that are partly indexical [Schiffer,S]
19509 The indexical aspect of contextual knowledge might be hidden, or it might be in what 'know' means [Schiffer,S]
19. Language / C. Assigning Meanings / 2. Semantics
19534 How does inferentialism distinguish the patterns of inference that are essential to meaning? [Williamson]
19535 Internalist inferentialism has trouble explaining how meaning and reference relate [Williamson]
19533 Inferentialist semantics relies on internal inference relations, not on external references [Williamson]
19. Language / C. Assigning Meanings / 7. Extensional Semantics
19532 Truth-conditional referential semantics is externalist, referring to worldly items [Williamson]
