Enneads V.6: The Superessential Principle Does Not Think; Which is the First
Good, Intelligence and Soul Are Like Light, Sun and Moon
4. As the Good must be simple, and self-sufficient, it has no need to think. Now that which it does not need could not be within it, since nothing (that is different from it) exists in it; consequently, thought does not exist in it (because it is essentially simple[12]). Besides, the Good is one thing, and Intelligence another; by thinking, Intelligence takes on the form of Good. Besides, when in two objects unity is joined to something other than itself, it is not possible that this unity, which is joined to something else, should be Unity itself. Unity in itself should exist in itself before this unity was joined to anything else. For the same reason, unity joined to something else presupposes absolutely simple Unity, which subsists in itself, and has nothing of what is found in unity joined to other things. How could one thing subsist in another if the principle, from which this other thing is derived, did not have an existence that was independent, and prior to the rest? What is simple cannot derive anything from any other source; but what is manifold, or at least indicates plurality, is of derivative (nature). The Good may be compared to light, Intelligence to the sun, and the Soul to the moon that derives her light from the sun. The Soul's intelligence is only borrowed, which intellectualizes her by coloring her with its light. On the contrary, Intelligence, in itself, possesses its own light; it is not only light, but it is essentially luminous. The Principle that illuminates Intelligence and which is nothing but light, is absolutely simple light, and supplies Intelligence with the power to be what it is. How could it need anything else? It is not similar to what exists in anything else; for what subsists in itself is very different from what subsists in something else.
AS THOUGHT IS INSPIRATION TO THE GOOD, INTELLIGENCE IMPLIES THE LATTER.
5. What is manifold needs to seek itself, and naturally desires to embrace itself, and to grasp itself by self-consciousness. But that which is absolutely One could not reflect on itself, and need self-consciousness. The absolutely identical principle is superior to consciousness and thought. Intelligence is not the first; it is not the first either by its essence, nor by the majestic value of its existence. It occupies only the second rank. It existed only when the Good already existed; and as soon as it existed, it turned towards the Good. In turning towards the Good, Intelligence cognized the latter; for thought consists of conversion towards the Good, and aspiration thereto. Aspiration towards the Good, therefore, produced thought, which identifies itself with the Good; for vision presupposes the desire to see. The Good, therefore, cannot think; for it has no good other than itself. Besides, when something other than the Good thinks the Good, it thinks the Good because it takes the form of the Good, and resembles the Good. It thinks, because itself becomes for itself a good and desirable object, and because it possesses an image of the Good. If this thing always remain in the same disposition, it will always retain this image of the Good. By thinking itself, Intelligence simultaneously thinks the Good; for it does not think itself as being actualized; yet every actualization has the Good as its goal.
