4. Formal Logic / F. Set Theory ST / 4. Axioms for Sets / j. Axiom of Choice IX
The Axiom of Choice needs a criterion of choice [Black]
7. Existence / E. Categories / 1. Categories
Categories can't overlap; they are either disjoint, or inclusive [Sommers, by Westerhoff]
9. Objects / A. Existence of Objects / 5. Individuation / b. Individuation by properties
Two things can only be distinguished by a distinct property or a distinct relation [Black]
9. Objects / F. Identity among Objects / 5. Self-Identity
The 'property' of self-identity is uselessly tautological [Black]
9. Objects / F. Identity among Objects / 7. Indiscernible Objects
If the universe just held two indiscernibles spheres, that refutes the Identity of Indiscernibles [Black]
27. Natural Reality / D. Time / 1. Nature of Time / h. Presentism
Presentists lack the materials for a realist view of change [Price,H]
27. Natural Reality / D. Time / 2. Passage of Time / d. Time series
The present moment, time's direction, and time's dynamic quality seem to be objective facts [Price,H]
27. Natural Reality / D. Time / 2. Passage of Time / g. Time's arrow
We must explain either the existence of a time direction, or our psychological sense of it [Price,H]
