The Identity Theory says a proposition is true if it coincides with what makes it true [Potter]
3. Truth / C. Correspondence Truth / 1. Correspondence Truth
It has been unfortunate that externalism about truth is equated with correspondence [Potter]

Set theory's three roles: taming the infinite, subject-matter of mathematics, and modes of reasoning [Potter]

Deductivism can't explain how the world supports unconditional conclusions [Potter]
5. Theory of Logic / H. Proof Systems / 3. Proof from Assumptions
Supposing axioms (rather than accepting them) give truths, but they are conditional [Potter]

Modern logical truths are true under all interpretations of the non-logical words [Potter]
