Enneads VI.7: How Ideas Multiplied, and the Good
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.
OF THE FIRST PRINCIPLE WE MAY NOT EVEN SAY THAT IT IS.
38Of the First we may not even say, “He is.” (He does not need this), since we do not either say of Him, “He is good.” “He is good” is said of the same principle to which “He is” applies. Now “He is” suits the (divinity) only on the condition that He be given no attribute, limiting oneself to the assertion of His existence. He is spoken of as the Good, not as predicating an attribute or quality of Him, but to indicate that He is the Good itself. We do not even approve of this expression, “He is the Good,” because we think that not even the article should be prefixed thereto; but inasmuch as our language would fail to express an entire negation or deprivation, then, to avoid introducing some diversity in it, we are forced to name it, but there is no need to say “it is,” we simply call it, “the Good.”
