1. Philosophy / E. Nature of Metaphysics / 6. Metaphysics as Conceptual

13919

Philosophy aims not at the 'analysis of concepts', but at understanding the essences of things [Lowe]

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

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

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

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

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

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

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

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

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 [Fisher]

5. Theory of Logic / F. Referring in Logic / 1. Naming / e. Empty names

18946

Unreflectively, we all assume there are nonexistents, and we can refer to them [Reimer]

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

13918

Holes, shadows and spots of light can coincide without being identical [Lowe]

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

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

9. Objects / D. Essence of Objects / 8. Essence as Explanatory

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 [Fisher]

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

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