ETERNITY IS SEMPITERNAL EXISTENCE.
5. (6). As this nature that is eternal and radiant with beauty refers to the One, issues from Him, and returns to Him, as it never swerves from Him, ever dwelling around Him and in Him, and lives according to Him, Plato was quite right[438] in saying not casually, but with great profundity of thought, that "eternity is immutable in unity." Thereby Plato not only reduces the eternity to the unity that it is in itself, but also relates the life of existence to the One itself. This life is what we seek; its permanence is eternity. Indeed that which remains in that manner, and which remains the same thing, that is, the actualization of that life which remains turned towards, and united with the One, that whose existence and life are not deceptive, that truly is eternity. (For intelligible or) true existence is to have no time when it does not exist, no time when it exists in a different manner; it is therefore to exist in an immutable manner without any diversity, without being first in one, and then in another state. To conceive of (existence), therefore, we must neither imagine intervals in its existence, nor suppose that it develops or acquires, nor believe that it contains any succession; consequently we could neither distinguish within it, or assert within it either before or after. If it contain neither "before" nor "after," if the truest thing that can be affirmed of it be that it is, if it exist as "being" and life, here again is eternity revealed. When we say that existence exists always, and that there is not one time in which it is, and another in which it is not, we speak thus only for the sake of greater clearness; for when we use the word "always," we do not take it in an absolute sense; but if we use it to show that existence is incorruptible, it might well mislead the mind in leading it to issue out from the unity (characteristic of eternity) to make it run through the manifold (which is foreign to eternity). "Always" further indicates that existence is never defective. It might perhaps be better to say simply "existence." But though the word "existence" suffices to designate "being," as several philosophers have confused "being" with generation, it was necessary to clear up the meaning of existence by adding the term "always." Indeed, though we are referring only to one and the same thing by "existence" and "existing always," just as when we say "philosopher," and "the true philosopher," nevertheless, as there are false philosophers, it has been necessary to add to the term "philosophers" the adjective "true." Likewise, it has been necessary to add the term "always" to that of "existing," and that of "existing" to that of "always;" that is the derivation of the expression "existing always," and consequently (by contraction), "aion," or, eternity. Therefore the idea "always" must be united to that of "existing," so as to designate the "real being."
THE CREATOR, BEING OUTSIDE OF TIME, PRECEDES THE UNIVERSAL ONLY AS ITS CAUSE.
"Always" must therefore be applied to the power which contains no interval in its existence, which has need of nothing outside of what it possesses, because it possesses everything, because it is every being, and thus lacks nothing. Such a nature could not be complete in one respect, but incomplete in another. Even if what is in time should appear complete, as a body that suffices the soul appears complete, though it be complete only for the soul; that which is in time needs the future, and consequently is incomplete in respect to the time it stands in need of; when it succeeds in enjoying the time to which it aspires, and succeeds in becoming united thereto, even though it still remain imperfect it still is called perfect by verbal similarity. But the existence whose characteristic it is not to need the future, not to be related to any other time—whether capable of being measured, or indefinite, and still to be indefinite—the existence that already possesses all it should possess is the very existence that our intelligence seeks out; it does not derive its existence from any particular quality, but exists before any quantity. As it is not any kind of quantity, it could not admit within itself any kind of quantity. Otherwise, as its life would be divided, it would itself cease to be absolutely indivisible; but existence must be as indivisible in its life as in its nature ("being"). (Plato's expression,[446]) "the Creator was good" does indeed refer to the notion of the universe, and indicates that, in the Principle superior to the universe, nothing began to exist at any particular time. Never, therefore, did the universe begin to exist within time, because though its Author existed "before" it, it was only in the sense that its author was the cause of its existence. But, after having used the word "was," to express this thought, Plato immediately corrects himself, and he demonstrates that this word does not apply to the Things that possess eternity.
TO STUDY TIME WE HAVE TO DESCEND FROM THE INTELLIGIBLE WORLD.
6. (7). Speaking thus of eternity, it is not anything foreign to us, and we do not need to consult the testimony of anybody but ourselves. For indeed, how could we understand anything that we could not perceive? How could we perceive something that would be foreign to us? We ourselves, therefore, must participate in eternity. But how can we do so, since we are in time? To understand how one can simultaneously be in time and in eternity, it will be necessary to study time. We must therefore descend from eternity to study time. To find eternity, we have been obliged to rise to the intelligible world; now we are obliged to descend therefrom to treat of time; not indeed descending therefrom entirely, but only so far as time itself descended therefrom.
B. TIME.
THE OPINIONS OF THE PHILOSOPHERS ABOUT TIME MUST BE STUDIED.
If those blessed ancient philosophers had not already uttered their views about time, we would only need to add to the idea of eternity what we have to say of the idea of time, and to set forth our opinion on the subject, trying to make it correspond with the already expressed notion of eternity. But we now must examine the most reasonable opinions that have been advanced about time, and observe how far our own opinion may conform thereto.
