The Epimenides paradox is a problem in logic. It is named after the Cretan philosopher Epimenides of Knossos (alive circa 600 BC), There is no single statement of the problem; a typical variation is given in the book Gödel, Escher, Bach, by Douglas Hofstadter: Epimenides was a Cretan who made one immortal statement: "All Cretans are liars." Interestingly, the Epistle to Titus makes reference to Epimenides: the author says of Cretans that "they are all liars, as one of their own has said." (Titus 1:12)
