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.

If 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.

For we are all sprung from earth and water

The 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.

The 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.

Even if a man should chance to speak the most complete truth, yet he himself does not know it; all things are wrapped in appearances

There is one god, greatest among gods and men, who bears no similarity to humans either in shape or thought... but humans believe that the gods are born like themselves, and that the gods wear clothes and have bodies like humans and speak in the same way... but if cows and horses or lions had hands or could draw with the hands and manufacture the things humans can make, then horses would draw the forms of gods like horses, cows like cows, and they would make the gods' bodies resemble those which each kind of animal had itself.
