They are all Fools who seem so besides half the rest. Folly arose with the world, and if there be any wisdom it is folly compared with the divine. But the greatest fool is he who thinks he is not one and all others are. To be wise It is not enough to seem wise, least of all to oneself. He knows who does not think that he knows, and he does not see who does not see that others see. Though all the world is full of fools, there is none that thinks himself one, or even suspects the fact.
