Around the sixth century BC in ancient Greece, a man named Epimenides lived in a place called Crete. He was well versed in philosophy and medicine, and could predict the future, and was respected as a "prophet". One day, he was discussing with others the question of whether the Cretans were honest, and he answered with this sentence: "All Cretans are liars."
If this sentence is true, then it means that the Cretan Epimenides told the truth, but it is contrary to "all Cretans are liars";
If this sentence is false, then the Cretan Epimenides told a lie, then the truth should be "not all people on Crete are liars", which is contrary to "all people on Crete are liars".
This paradox is called the "Liar's Paradox."
No true liar can be found in Crete.
