"This, then, which imparts truth to the things that are known and the power of knowing to the knower, you may affirm to be the Form of the good. It is the cause of knowledge and truth, and you may conceive it as being known, but while knowledge and truth are both beautiful, you will be right in thinking it other and fairer than these. And as in the other world it is right to think light and sight sunlike, but not right to think them the sun, so here it is right to think both knowledge and truth like the good, but not right to think either of them the good. The state or nature of the good must be honoured still more highly."

[Plato 192-193]
