To claim that mathematical truths are conventional in the sense of following logically from definitions is the claim that mathematics is a part of logic.

A Reaction
Quine is about to attack logic as convention, so he is endorsing the logicist programme (despite his awareness of Gödel), but resisting the full Wittgenstein conventionalist picture.
