All that is moved must have a direction towards which it is moved; we must therefore conclude that that which has no direction towards which it is moved must be at a stand-still, and that anything born of this principle must be born without causing this principle to cease being turned towards itself. We must, however, remove from our mind the idea of a generation operated within time, for we are here treating of eternal things. When we apply to them the conception of generation, we mean only a relation of causality and effect. What is begotten by the One must be begotten by Him without any motion on the part of the One; if He were moved, that which was begotten from Him would, because of this movement, be ranked third, instead of second.[236] Therefore, since the One is immovable, He produces the hypostatic (form of existence) which is ranked second, without volition, consent, or any kind of movement. What conception are we then to form of this generation of Intelligence by this immovable Cause? It is a radiation of light which escapes without disturbing its quietness, like the splendor which emanates perpetually from the sun, without affecting its quietness, which surrounds it without leaving it. Thus all things, in so far as they remain within existence, necessarily draw from their own essence ("being") and produce externally a certain nature that depends on their power, and that is the image of the archetype from which it is derived.[237] Thus does fire radiate heat; thus snow spreads cold. Perfumes also furnish a striking example of this process; so long as they last, they emit exhalations in which everything that surrounds them participates. Everything that has arrived to its point of perfection begets something. That which is eternally perfect begets eternally; and that which it begets is eternal though inferior to the generating principle. What then should we think of Him who is supremely perfect? Does He not beget? On the contrary, He begets that which, after Him, is the greatest. Now that which, after Him, is the most perfect, is the second rank principle, Intelligence. Intelligence contemplates Unity, and needs none but Him; but the Unity has no need of Intelligence. That which is begotten by the Principle superior to Intelligence can be nothing if not Intelligence; for it is the best after the One, since it is superior to all other beings. The Soul, indeed, is the word and actualization of Intelligence, just as Intelligence is word and actualization of the One. But the Soul is an obscure word. Being an image of Intelligence, she must contemplate Intelligence, just as the latter, to subsist, must contemplate the One. Intelligence contemplates the One, not because of any separation therefrom, but only because it is after the One. There is no intermediary between the One and Intelligence, any more than between Intelligence and the Soul. Every begotten being desires to unite
