Cretan (n.)

Old English Cretense (plural), "natives or inhabitants of Crete, from Latin Cretanus (singular); see Crete. They were proverbial in ancient times as liars; compare Greek noun kretismos "lying," literally "Cretan behavior," and the classical sophism expressing the liar paradox (see one version below).  Alternative Cretic (c. 1600) was used especially of a form of verse.

Epimenides, the Cretan, says that all Cretans are liars.

If Epimenides' statement is not true, he is a liar; and if it is true, he is a liar, for he is a Cretan.

But his statement is either true or not true.

Therefore he is a liar.

But since he is a liar, his statement is not true that all Cretans are liars.

Therefore some Cretans are not liars.

But since some Cretans are not liars, Epimenides is not necessarily a liar because he is a Cretan.

Therefore, we may accept his statement that all Cretans are liars. And so on.
