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 sea is the source of water and the source of wind; for neither would blasts of wind arise in the clouds and blow out from within them, except for the great sea, nor would the streams of rivers nor the rain-water in the sky exist but for the sea ; but the great sea is the begetter of clouds and winds and rivers.
XenophanesIf oxen and lions had hands and could paint with their hands and produce works of art, as men do, horses would paint the forms of the gods likes horses and oxen like oxen. Each would represent them with bodies according to the bodies of each. So the Ethiopians make their gods black and snub-nosed; the Thracians give theirs red hair and blue eyes.
