Epimenides, a Greek philosopher of the 6th century BC, was the first to present one of the most famous paradoxes of all time: The “liar’s paradox.”
A resident of Crete, he declared that “All Cretans are liars.” If we assume that Epimenides was telling the truth and that all Cretans are liars, it follows that he too is a liar, by virtue of being a Cretan, and therefore his statement that “all Cretans are liars” is false, creating a paradox.
