Two red cloths are separate instances of redness, because you can dye one of them blue [Campbell,K]
Red could only recur in a variety of objects if it was many, which makes them particulars [Campbell,K]
Tropes solve the Companionship Difficulty, since the resemblance is only between abstract particulars [Campbell,K]
Tropes solve the Imperfect Community problem, as they can only resemble in one respect [Campbell,K]
Trope theory makes space central to reality, as tropes must have a shape and size [Campbell,K]

Nominalism has the problem that without humans nothing would resemble anything else [Campbell,K]
9. Objects / A. Existence of Objects / 1. Physical Objects

Scepticism has two dogmas: that nothing is definable, and every argument has an opposite argument [Diog. Laertius]
13. Knowledge Criteria / D. Scepticism / 6. Scepticism Critique
When sceptics say that nothing is definable, or all arguments have an opposite, they are being dogmatic [Diog. Laertius]

Induction moves from some truths to similar ones, by contraries or consequents [Diog. Laertius]

Abstractions come before the mind by concentrating on a part of what is presented [Campbell,K]
22. Metaethics / C. The Good / 3. Pleasure / b. Types of pleasure

Causal conditions are particular abstract instances of properties, which makes them tropes [Campbell,K]
Davidson can't explain causation entirely by events, because conditions are also involved [Campbell,K]
