I think a form of logicism (the view that mathematical statements are logical tautologies in disguise) is true at least for arithmetic. There are some ways to interpret them using logical truths from pure higher-order logic. I'm not sure about most other parts of mathematics.

I think they are testable by performing conceptual analysis, which consists in organizing data from semantic intuitions about the involved concepts.
