By digging into the question of truth, you discover a whole cemetery of philosophical and mathematical dead bodies. For example,

...
The moral: an adequate theory must allow our statements involving the notion of truth to be risky: they risk being paradoxical if the empirical facts are extremely (and unexpectedly) unfavorable. There can be no syntactic or semantic "sieve" that will winnow out the "bad" cases while preserving the "good" ones.
