THE FIRST PRINCIPLE HAS NO FUNCTION.
That is why Plato rightly says that the Good is above Intelligence. To speak of an "unthinking" intelligence would be a self-contradiction; for the principle whose nature it is to think necessarily ceases to be intelligent if it does not think. But no function can be assigned to a principle that has none, and we cannot blame it for idleness because it does not fulfil some function; this would be as silly as to reproach it for not possessing the art of healing. To the first Principle then should be assigned no function, because there is none that would suit Him. He is (self) sufficient, and there is nothing outside of Him who is above all; for, in being what He is, He suffices Himself and everything else.
