Well, I'm open to the idea that "truth is a lie" but then you'd have to persuade me, and I don't think you can.
Besides, a lot of mathematicians don't really see solid truth in what they do. Philosophically speaking they just see a system that works, like rules in chess.

Platonism is the form of realism that suggests that mathematical entities are abstract, have no spatiotemporal or causal properties, and are eternal and unchanging.
Formalism holds that mathematical statements may be thought of as statements about the consequences of certain string manipulation rules. (Mathematics is a game)
Gödel's platonism postulates a special kind of mathematical intuition that lets us perceive mathematical objects directly. (This view bears resemblances to many things Husserl said about mathematics, and supports Kant's idea that mathematics is synthetic a priori.) Davis and Hersh have suggested in their book The Mathematical Experience that most mathematicians act as though they are Platonists, even though, if pressed to defend the position carefully, they may retreat to formalism.
