5. Theory of Logic / E. Structures of Logic / 6. Relations in Logic

8525	Relations need terms, so they must be second-order entities based on first-order tropes

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

8518	Events are trope-sequences, in which tropes replace one another

8. Modes of Existence / B. Properties / 13. Tropes / a. Nature of tropes

8513	Two red cloths are separate instances of redness, because you can dye one of them blue

8514	Red could only recur in a variety of objects if it was many, which makes them particulars

8522	Tropes solve the Companionship Difficulty, since the resemblance is only between abstract particulars

8523	Tropes solve the Imperfect Community problem, as they can only resemble in one respect

8524	Trope theory makes space central to reality, as tropes must have a shape and size

8. Modes of Existence / E. Nominalism / 2. Resemblance Nominalism

8521	Nominalism has the problem that without humans nothing would resemble anything else

9. Objects / A. Existence of Objects / 1. Physical Objects

8515	Tropes are basic particulars, so concrete particulars are collections of co-located tropes

8519	Bundles must be unique, so the Identity of Indiscernibles is a necessity - which it isn't!

9. Objects / F. Identity among Objects / 7. Indiscernible Objects

4033	Two pure spheres in non-absolute space are identical but indiscernible

18. Thought / E. Abstraction / 3. Abstracta by Ignoring

8512	Abstractions come before the mind by concentrating on a part of what is presented

26. Natural Theory / C. Causation / 8. Particular Causation / b. Causal relata

8516	Davidson can't explain causation entirely by events, because conditions are also involved

8517	Causal conditions are particular abstract instances of properties, which makes them tropes
