Enneads III.7: Of Time and Eternity
The Nature of Time Will Be Revealed by Its Origin
10. (11). To accomplish this we shall have to return to the nature which, as we pointed out above, was essential to eternity; that immutable life, wholly realized all at once, infinite and perfect, subsisting in, and referring to unity. Time was not yet, or at least, it did not yet exist for the intelligible entities. Only, it was yet to be born of them,[458] because (as was the world), time, by both its reason and nature, was posterior to the (intelligible entities[459]). Are we trying to understand how time issued from among intelligible entities while these were resting within themselves? Here it would be useless to call upon the Muses, for they did not yet exist. Still this might perhaps not be useless; for (in a certain sense, that time had already begun, then, so far as they existed within the sense-world) they existed already. In any case, the birth of time will be plain enough if we consider it only as it is born and manifested. Thus much can be said about it.
TIME AROSE AS MEASUREMENT OF THE ACTIVITY OF THE UNIVERSAL SOUL.
Before priority and posteriority, time, which did not yet exist, brooded within existence itself. But an active nature (the universal Soul), which desired to be mistress of herself, to possess herself, and ceaselessly to add to the present, entered into motion, as did time, along with (the Soul). We achieve a representation of the time that is the image of eternity, by the length that we must go through with to reach what follows, and is posterior, towards one moment, and then towards another.[460]
LIKE TIME, SPACE IS THE RESULT OF THE PROCESSION OF THE UNIVERSAL SOUL.
As the universal Soul contained an activity that agitated her, and impelled her to transport into another world what she still saw on high, she was willing to retain all things that were present at the same time. (Time arose not by a single fiat, but as the result of a process. This occurred within the universal Soul, but may well be first illustrated by the more familiar process within) Reason, which distributes unity, not indeed That which remains within itself, but that which is exterior to itself. Though this process seem to be a strengthening one, reason developing out of the seed in which it brooded unto manifoldness, it is really a weakening (or destructive one), inasmuch as it weakened manifoldness by division, and weakened reason by causing it to extend. The case was similar with the universal Soul. When she produced the sense-world, the latter was animated by a movement which was only an image of intelligible movement. (While trying to strengthen) this image-movement to the extent of the intelligible movement, she herself (weakened), instead of remaining exclusively eternal, became temporal and (involuntarily) subjected what she had produced to the conditions of time, transferring entirely into time not only the universe, but also all its revolutions. Indeed, as the world moves within the universal Soul, which is its location, it also moves within the time that this Soul bears within herself.[461] Manifesting her power in a varied and successive manner, by her mode of action, the universal Soul begat succession. Indeed, she passes from one conception to another, and consequently to what did not exist before, since this conception was not effective, and since the present life of the soul does not resemble her former life. Her life is varied, and from the variety of her life results the variety of time.[462]
TIME IS THE LIFE OF THE SOUL CONSIDERED IN THE MOVEMENT BY WHICH SHE PASSES FROM ONE ACTUALIZATION TO ANOTHER.
Thus, the extension of the life of the soul produces time, and the perpetual progression of her life produces the perpetuity of time, and her former life constitutes the past. We may therefore properly define time as the life of the soul considered in the movement by which she passes from one actualization to another.
WHAT ETERNITY IS TO INTELLIGENCE, TIME IS TO THE UNIVERSAL SOUL.
We have already decided that eternity is life characterized by rest, identity, immutability and infinity (in intelligence). It is, further, (admitted that) this our world is the image of the superior World (of intelligence). We have also come to the conclusion that time is the image of eternity. Consequently, corresponding to the Life characteristic of Intelligence, this world must contain another life which bears the same name, and which belongs to that power of the universal Soul. Instead of the movement of Intelligence, we will have the movement characteristic of a part of the soul (as the universal Soul ceaselessly passes from one thought to another). Corresponding to the permanence, identity, and immutability (of Intelligence), we will have the mobility of a principle which ceaselessly passes from one actualization to another. Corresponding to the unity and the absence of all extension, we will have a mere image of unity, an image which exists only by virtue of continuity. Corresponding to an infinity already entirely present, we will have a progression towards infinity which perpetually tends towards what follows. Corresponding to what exists entirely at the same time, we will have what exists by parts, and what will never exist entire at the same time. The soul's existence will have to be ceaseless acquiring of existence; if it is to reveal an image of the complete, universal and infinite existence of the soul; that is the reason its existence is able to represent the intelligible existence.
TIME IS AS INTERIOR TO THE SOUL AS ETERNITY IS TO EXISTENCE.
Time, therefore, is not something external to the soul, any more than eternity is exterior to existence. It is neither a consequence nor a result of it, any more than eternity is a consequence of existence. It appears within the soul, is in her and with her, as eternity is in and with existence.
TIME IS THE LENGTH OF THE LIFE OF THE UNIVERSAL SOUL.
11. (12). The result of the preceding considerations is that time must be conceived of as the length of the life characteristic of the universal Soul; that her course is composed of changes that are equal, uniform, and insensible, so that that course implies a continuity of action. Now let us for a moment suppose that the power of the Soul should cease to act, and to enjoy the life she at present possesses without interruption or limit, because this life is the activity characteristic of an eternal Soul, an action by which the Soul does not return upon herself, and does not concentrate on herself, though enabling her to beget and produce. Now supposing that the Soul should cease to act, that she should apply her superior part to the intelligible world, and to eternity, and that she should there remain calmly united--what then would remain, unless eternity? For what room for succession would that allow, if all things were immovable in unity? How could she contain priority, posteriority, or more or less duration of time? How could the Soul apply herself to some object other than that which occupies her? Further, one could not then even say that she applied herself to the subject that occupied her; she would have to be separated therefrom in order to apply herself thereto. Neither would the universal Sphere exist, since it does not exist before time, because it exists and moves within time. Besides, even if this Sphere were at rest during the activity of the Soul, we could measure the duration of her rest because this rest is posterior to the rest of eternity. Since time is annihilated so soon as the Soul ceases to act, and concentrates in unity, time must be produced by the beginning of the Soul's motion towards sense-objects, by the Soul's life. Consequently (Plato[463]) says that time is born with the universe, because the Soul produced time with the universe; for it is this very action of the Soul which has produced this universe. This action constitutes time, and the universe is within time. Plato does indeed call the movements of the stars, time; but evidently only figuratively, as (Plato) subsequently says that the stars were created to indicate the divisions of time, and to permit us to measure it easily.
