Epimenides

"It's a latter-day illustration of the ancient paradox: Cretans always lie, said the Cretan."

Sigh. A Cretan saying that Cretans always lie does not produce a paradox. All that is necessary is to assume that:

• Cretans sometimes lie and sometimes tell the truth;
• This particular Cretan, on this particular occasion, is lying.

No paradox. Watch your freaking quantifiers, people!
