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.
XenophanesThe clear and perfect truth no man has seen, nor will there be anyone who knows about the gods and what I say about all things...; for, however perfect what he says may be, yet he does not know it; all things are matters of opinion.
Xenophanes...for our wisdom is better than the strength of men or of horses. ... nor is it right to prefer strength to excellent wisdom. For if there should be in the city [any athlete whose skill] is honoured more than strength ... the city would not on that account be any better governed.
Xenophanes
