2. Reason / A. Nature of Reason / 1. On Reason

8952	We reach 'reflective equilibrium' when intuitions and theory completely align

4. Formal Logic / E. Nonclassical Logics / 3. Many-Valued Logic

8943	Three-valued logic says excluded middle and non-contradition are not tautologies

4. Formal Logic / E. Nonclassical Logics / 4. Fuzzy Logic

8945	Fuzzy logic has many truth values, ranging in fractions from 0 to 1

5. Theory of Logic / A. Overview of Logic / 6. Classical Logic

8951	Classical logic is: excluded middle, non-contradiction, contradictions imply all, disjunctive syllogism

5. Theory of Logic / C. Ontology of Logic / 2. Platonism in Logic

8950	Logic formalizes how we should reason, but it shouldn't determine whether we are realists

7. Existence / D. Theories of Reality / 10. Vagueness / g. Degrees of vagueness

8946	We could make our intuitions about heaps precise with a million-valued logic

9. Objects / B. Unity of Objects / 3. Unity Problems / e. Vague objects

8944	Vagueness can involve components (like baldness), or not (like boredom)

10. Modality / B. Possibility / 1. Possibility

8941	We can't explain 'possibility' in terms of 'possible' worlds

10. Modality / B. Possibility / 8. Conditionals / c. Truth-function conditionals

8947	If all truths are implied by a falsehood, then not-p might imply both q and not-q

10. Modality / B. Possibility / 8. Conditionals / d. Non-truthfunction conditionals

8949	In relevance logic, conditionals help information to flow from antecedent to consequent
