First: it is not essential that everything seen should be laid up in the mind; for when the object is of no importance, or of no personal concern, the sensitive faculty, stimulated by the differences in the objects present to vision, acts without accompaniment of the will, and is alone in entertaining the impression.The soul does not take into its deeper recesses such differences as do not meet any of its needs, or serve any of its purposes.Above all, when the soul's act is directed towards another order, it must utterly reject the memory of such things, things over and done with now, and not even taken into knowledge when they were present.
On the second point: circumstances, purely accidental, need not be present to the imaging faculty, and if they do so appear they need not be retained or even observed, and in fact the impression of any such circumstance does not entail awareness.Thus in local movement, if there is no particular importance to us in the fact that we pass through first this and then that portion of air, or that we proceed from some particular point, we do not take notice, or even know it as we walk.Similarly, if it were of no importance to us to accomplish any given journey, mere movement in the air being the main concern, we would not trouble to ask at what particular point of place we were, or what distance we had traversed; if we have to observe only the act of movement and not its duration, nothing to do which obliges us to think of time, the minutes are not recorded in our minds.
And finally, it is of common knowledge that, when the understanding is possessed of the entire act undertaken and has no reason to foresee any departure from the normal, it will no longer observe the detail; in a process unfailingly repeated without variation, attention to the unvarying detail is idleness.
So it is with the stars.They pass from point to point, but they move on their own affairs and not for the sake of traversing the space they actually cover; the vision of the things that appear on the way, the journey by, nothing of this is their concern: their passing this or that is of accident not of essence, and their intention is to greater objects: moreover each of them journeys, unchangeably, the same unchanging way; and again, there is no question to them of the time they spend in any given section of the journey, even supposing time division to be possible in the case.All this granted, nothing makes it necessary that they should have any memory of places or times traversed.Besides this life of the ensouled stars is one identical thing [since they are one in the All-Soul] so that their very spatial movement is pivoted upon identity and resolves itself into a movement not spatial but vital, the movement of a single living being whose act is directed to itself, a being which to anything outside is at rest, but is in movement by dint of the inner life it possesses, the eternal life.Or we may take the comparison of the movement of the heavenly bodies to a choral dance; if we think of it as a dance which comes to rest at some given period, the entire dance, accomplished from beginning to end, will be perfect while at each partial stage it was imperfect: but if the dance is a thing of eternity, it is in eternal perfection.And if it is in eternal perfection, it has no points of time and place at which it will achieve perfection; it will, therefore, have no concern about attaining to any such points: it will, therefore, make no measurements of time or place; it will have, therefore, no memory of time and place.
If the stars live a blessed life in their vision of the life inherent in their souls, and if, by force of their souls' tendency to become one, and by the light they cast from themselves upon the entire heavens, they are like the strings of a lyre which, being struck in tune, sing a melody in some natural scale...if this is the way the heavens, as one, are moved, and the component parts in their relation to the whole- the sidereal system moving as one, and each part in its own way, to the same purpose, though each, too, hold its own place- then our doctrine is all the more surely established; the life of the heavenly bodies is the more clearly an unbroken unity.
9.But Zeus- ordering all, governor, guardian and disposer, possessor for ever of the kingly soul and the kingly intellect, bringing all into being by his providence, and presiding over all things as they come, administering all under plan and system, unfolding the periods of the kosmos, many of which stand already accomplished- would it not seem inevitable that, in this multiplicity of concern, Zeus should have memory of all the periods, their number and their differing qualities? Contriving the future, co-ordinating, calculating for what is to be, must he not surely be the chief of all in remembering, as he is chief in producing?
Even this matter of Zeus' memory of the kosmic periods is difficult; it is a question of their being numbered, and of his knowledge of their number.A determined number would mean that the All had a beginning in time [which is not so]; if the periods are unlimited, Zeus cannot know the number of his works.
The answer is that he will know all to be one thing existing in virtue of one life for ever: it is in this sense that the All is unlimited, and thus Zeus' knowledge of it will not be as of something seen from outside but as of something embraced in true knowledge, for this unlimited thing is an eternal indweller within himself- or, to be more accurate, eternally follows upon him- and is seen by an indwelling knowledge; Zeus knows his own unlimited life, and, in that knowledge knows the activity that flows from him to the kosmos; but he knows it in its unity not in its process.
10.The ordering principle is twofold; there is the principle known to us as the Demiurge and there is the Soul of the All; we apply the appellation "Zeus" sometimes to the Demiurge and sometimes to the principle conducting the universe.
