4. Formal Logic / D. Modal Logic ML / 3. Modal Logic Systems / b. System K
14970 Normal system K has five axioms and rules [Cresswell]
4. Formal Logic / D. Modal Logic ML / 3. Modal Logic Systems / c. System D

4. Formal Logic / D. Modal Logic ML / 3. Modal Logic Systems / g. System S4
14972 S4 has 14 modalities, and always reduces to a maximum of three modal operators [Cresswell]

14973 In S5 all the long complex modalities reduce to just three, and their negations [Cresswell]
4. Formal Logic / D. Modal Logic ML / 7. Barcan Formula
14976 Reject the Barcan if quantifiers are confined to worlds, and different things exist in other worlds [Cresswell]
8. Modes of Existence / A. Relations / 4. Formal Relations / a. Types of relation

13. Knowledge Criteria / B. Internal Justification / 3. Evidentialism / b. Evidentialism
19520 Evidentialism is not axiomatic; the evidence itself inclines us towards evidentialism [Conee]
13. Knowledge Criteria / C. External Justification / 3. Reliabilism / b. Anti-reliabilism
19521 If pure guesses were reliable, reliabilists would have to endorse them [Conee]
19522 More than actual reliability is needed, since I may mistakenly doubt what is reliable [Conee]
19523 Reliabilism is poor on reflective judgements about hypothetical cases [Conee]
13. Knowledge Criteria / C. External Justification / 6. Contextual Justification / a. Contextualism
19555 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
19557 Maybe low knowledge standards are loose talk; people will deny that it is 'really and truly' knowledge [Conee]
19556 Maybe knowledge has fixed standards (high, but attainable), although people apply contextual standards [Conee]
12890 That standards vary with context doesn't imply different truth-conditions for judgements [Conee]
12892 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
16571 Prime matter is exceptionally obscure [Zabarella]
