Enneads V.4: How What is After the First Proceeds Therefrom; of the One
The First and Second as Higher and Lower Intelligible Entities
But besides this intelligible (entity, namely, intelligence), there is another (higher) intelligible (the supreme Intelligible, the First). In what way does the intelligence, thus determined, proceed from the (First) Intelligible? The Intelligible abides in itself, and has need of nothing else, while there is a need of something else in that which sees and thinks (that is, that which thinks has need of contemplating the supreme Intelligible). But even while remaining within Himself, the Intelligible (One) is not devoid of sentiment; all things belong to Him, are in Him, and with Him. Consequently, He has the conception of Himself, a conception which implies consciousness, and which consists in eternal repose, and in a thought, but in a thought different from that of intelligence. If He begets something while remaining within Himself, He begets it precisely when He is at the highest point of individuality. It is therefore by remaining in His own state that He begets what He begets; He procreates by individualizing. Now as He remains intelligible, what He begets cannot be anything else than thought; therefore thought, by existing, and by thinking the Principle whence it is derived (for it could not think any other object), becomes simultaneously intelligence and intelligible; but this second intelligible differs from the first Intelligible from which it proceeds, and of which it is but the image and the reflection.
THE SECOND IS THE ACTUALIZATION OF THE POTENTIALITY OF THE FIRST.
But how is an actualization begotten from that self-limited (intelligible)? We shall have to draw a distinction between an actualization of being, and an actualization out of the being of each thing (actualized being, and actualization emanating from being). Actualized being cannot differ from being, for it is being itself. But the actualization emanating from being--and everything necessarily has an actualization of this kind--differs from what produces it. It is as if with fire: there is a difference between the heat which constitutes its being, and the heat which radiates exteriorly, while the fire interiorly realizes the actualization which constitutes its being, and which makes it preserve its nature. Here also, and far more so, the First remains in His proper state, and yet simultaneously, by His inherent perfection, by the actualization which resides in Him, has been begotten the actualization which, deriving its existence from so great a power, nay, from supreme Power, has arrived at, or achieved essence and being. As to the First, He was above being; for He was the potentiality of all things, already being all things.
If this (actualization begotten by the First, this external actualization) be all things, then that (One) is above all things, and consequently above being. If then (this external actualization) be all things, and be before all things, it does not occupy the same rank as the remainder (of all other things); and must, in this respect also, be superior to being, and consequently also to intelligence; for there is Something superior to intelligence. Essence is not, as you might say, dead; it is not devoid of life or thought; for intelligence and essence are identical. Intelligible entities do not exist before the intelligence that thinks them, as sense-objects exist before the sensation which perceives them. Intelligence itself is the things that it thinks, since their forms are not introduced to them from without. From where indeed would intelligence receive these forms? Intelligence exists with the intelligible things; intelligence is identical with them, is one with them. Reciprocally, intelligible entities do not exist without their matter (that is, Intelligence).
