Truthful Liars: How They are Possible

I claim that truth is not a norm of belief and assertion in the sense that having a belief and making an assertion commit us to the truth of what is believed and asserted. I try to show that making an assertion commits one to sincerity, not to truth. But of course this does not throw the concept of truth out of the picture: since asserting that p is asserting that one believes that p, and believing that p is believing that p is true, making an assertion we are committed to believe that what we say is true. Similarly for belief: even though believing that p is believing that p is true, having a belief does not really commit one to truth, but to justification.
This explains how it is possible to be a truthful liar, namely one who asserts that p while he believes that non-p and it is in fact true that p.
