No human being will ever know the truth, for even if they happen to say it by chance, they would not even know they had done so.
XenophanesIf cows and horses had hands and could draw, cows would draw gods that look like cows and horses would draw gods that look like horses.
XenophanesThe Gods did not reveal, from the beginning, all things to us, but in the course of time through seeking we may learn & know things better. But as for certain truth no man knows it, nor shall he know it, neither of the Gods nor yet of all things that I speak. For even if by chance he were to utter The Final Truth, he would himself not know it: for all is but a woven web of guesses.
Xenophanes
