10 ideas

4. Formal Logic / F. Set Theory ST / 3. Types of Set / e. Equivalence classes

8920	Equivalence relations are reflexive, symmetric and transitive, and classify similar objects [Lipschutz]

5. Theory of Logic / D. Assumptions for Logic / 2. Excluded Middle

7334	Anti-realism needs an intuitionist logic with no law of excluded middle [Dummett, by Miller,A]

7. Existence / B. Change in Existence / 4. Events / a. Nature of events

15567

Some events involve no change; they must, because causal histories involve unchanges [Lewis]

15561

The events that suit semantics may not be the events that suit causation [Lewis]

15565

Events have inbuilt essences, as necessary conditions for their occurrence [Lewis]

15566

Events are classes, and so there is a mereology of their parts [Lewis]

7. Existence / B. Change in Existence / 4. Events / c. Reduction of events

15564

An event is a property of a unique space-time region [Lewis]

7. Existence / D. Theories of Reality / 4. Anti-realism

3303	For anti-realists there are no natural distinctions between objects [Dummett, by Benardete,JA]

8. Modes of Existence / B. Properties / 10. Properties as Predicates

15563

Properties are very abundant (unlike universals), and are used for semantics and higher-order variables [Lewis]

26. Natural Theory / C. Causation / 1. Causation

15562

Causation is a general relation derived from instances of causal dependence [Lewis]
