###### 5. Theory of Logic / B. Logical Consequence / 1. Logical Consequence
 18755 Validity is explained as truth in all models, because that relies on the logical terms [McGee]
###### 5. Theory of Logic / E. Structures of Logic / 2. Logical Connectives / a. Logical connectives
 18751 Natural language includes connectives like 'because' which are not truth-functional [McGee]
###### 5. Theory of Logic / G. Quantification / 5. Second-Order Quantification
 18761 Second-order variables need to range over more than collections of first-order objects [McGee]
###### 5. Theory of Logic / I. Semantics of Logic / 1. Semantics of Logic
 18753 An ontologically secure semantics for predicate calculus relies on sets [McGee]
###### 5. Theory of Logic / I. Semantics of Logic / 3. Logical Truth
 18754 Logically valid sentences are analytic truths which are just true because of their logical words [McGee]
###### 5. Theory of Logic / K. Features of Logics / 3. Soundness
 18757 Soundness theorems are uninformative, because they rely on soundness in their proofs [McGee]
###### 6. Mathematics / B. Foundations for Mathematics / 3. Axioms for Geometry
 18760 The culmination of Euclidean geometry was axioms that made all models isomorphic [McGee]
###### 9. Objects / A. Existence of Objects / 5. Individuation / e. Individuation by kind
 16235 Persistence conditions cannot contradict, so there must be a 'dominant sortal' [Burke,M, by Hawley]
 14753 The 'dominant' of two coinciding sortals is the one that entails the widest range of properties [Burke,M, by Sider]
###### 9. Objects / B. Unity of Objects / 1. Unifying an Object / b. Unifying aggregates
 16072 'The rock' either refers to an object, or to a collection of parts, or to some stuff [Burke,M, by Wasserman]
###### 9. Objects / B. Unity of Objects / 3. Unity Problems / b. Cat and its tail
 14751 Tib goes out of existence when the tail is lost, because Tib was never the 'cat' [Burke,M, by Sider]
###### 9. Objects / B. Unity of Objects / 3. Unity Problems / c. Statue and clay
 16071 Sculpting a lump of clay destroys one object, and replaces it with another one [Burke,M, by Wasserman]
 16234 Burke says when two object coincide, one of them is destroyed in the process [Burke,M, by Hawley]
 13278 Maybe the clay becomes a different lump when it becomes a statue [Burke,M, by Koslicki]
###### 9. Objects / B. Unity of Objects / 3. Unity Problems / d. Coincident objects
 14750 Two entities can coincide as one, but only one of them (the dominant sortal) fixes persistence conditions [Burke,M, by Sider]
###### 15. Nature of Minds / A. Nature of Mind / 4. Other Minds / b. Scepticism of other minds
 1799 If we can't know minds, we can't know if Pyrrho was a sceptic [Theodosius, by Diog. Laertius]
###### 19. Language / F. Communication / 2. Assertion
 18762 A maxim claims that if we are allowed to assert a sentence, that means it must be true [McGee]
