4. Formal Logic / B. Propositional Logic PL / 1. Propositional Logic
Boole applied normal algebra to logic, aiming at an algebra of thought [Boole, by Devlin]
Boole's notation can represent syllogisms and propositional arguments, but not both at once [Boole, by Weiner]
5. Theory of Logic / A. Overview of Logic / 2. History of Logic
Boole made logic more mathematical, with algebra, quantifiers and probability [Boole, by Friend]
5. Theory of Logic / H. Proof Systems / 2. Axiomatic Proof
Boole's method was axiomatic, achieving economy, plus multiple interpretations [Boole, by Potter]
8. Modes of Existence / C. Powers and Dispositions / 3. Powers as Derived
A power is not a cause, but an aptitude for a cause [Zabarella]
13. Knowledge Criteria / B. Internal Justification / 3. Evidentialism / b. Evidentialism
Evidentialism is not axiomatic; the evidence itself inclines us towards evidentialism [Conee]
13. Knowledge Criteria / C. External Justification / 3. Reliabilism / b. Anti-reliabilism
If pure guesses were reliable, reliabilists would have to endorse them [Conee]
More than actual reliability is needed, since I may mistakenly doubt what is reliable [Conee]
Reliabilism is poor on reflective judgements about hypothetical cases [Conee]
13. Knowledge Criteria / C. External Justification / 6. Contextual Justification / a. Contextualism
People begin to doubt whether they 'know' when the answer becomes more significant [Conee]
13. Knowledge Criteria / C. External Justification / 6. Contextual Justification / b. Invariantism
Maybe knowledge has fixed standards (high, but attainable), although people apply contextual standards [Conee]
Maybe low knowledge standards are loose talk; people will deny that it is 'really and truly' knowledge [Conee]
That standards vary with context doesn't imply different truth-conditions for judgements [Conee]
Maybe there is only one context (the 'really and truly' one) for serious discussions of knowledge [Conee]
26. Natural Theory / A. Speculations on Nature / 6. Early Matter Theories / b. Prime matter
Prime matter is exceptionally obscure [Zabarella]
