What exactly is the relationship between G�del's fixed point lemma and 
any of the two recursion theorems?

Thanks.

If Jack says �What I am saying at this very moment is not true�, we can 
successfully and truly assert that he did not utter a truth: �What Jack 
said is not true�. But it is hardly conceivable that Jack�s utterance is 
true by virtue of its success in attributing non-truth to itself.
