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.
