(10) Time, again, has been described as some sort of a sequence upon Movement, but we learn nothing from this, nothing is said, until we know what it is that produces this sequential thing: probably the cause and not the result would turn out to be Time.

And, admitting such a thing, there would still remain the question whether it came into being before the movement, with it, or after it; and, whether we say before or with or after, we are speaking of order in Time: and thus our definition is "Time is a sequence upon movement in Time!"

Enough: Our main purpose is to show what Time is, not to refute false definition. To traverse point by point the many opinions of our many predecessors would mean a history rather than an identification; we have treated the various theories as fully as is possible in a cursory review: and, notice, that which makes Time the Measure of the All-Movement is refuted by our entire discussion and, especially, by the observations upon the Measurement of Movement in general, for all the argument- except, of course, that from irregularity- applies to the All as much as to particular Movement.

We are, thus, at the stage where we are to state what Time really is.

(11) The following statement from a modern text book may serve to point to the difference between the conception of Pure Duration, and Time: "Pure Duration is conceived without regard to the motions of changes in things. Time on the contrary is the sensible measure of any portion of duration, often marked by particular phenomena, as the apparent revolution of the celestial bodies, the rotation of the earth on its axis, etc. Our conception of Time originates in that of motions; and particularly in those regular and equable motions carried on in the heavens, the parts of which, from their perfect similarity to each other, are correct measures of the continuous and successive quantity called Time, with which they are conceived to co-exist. Time, therefore, may be defined as, The perceived number of successive movements. Time, based upon the movements of the celestial bodies, or the earth, is frequently measured by instruments based upon such movements, such as watches, clocks, sun-dials, etc." We are also conscious of the passage of Time by changes in our mental states, our thoughts, our mental images, etc., both in the waking state or the state of dreams. Without changes in the outside world, represented to our consciousness by perceptions of such changes, or without changes in our mental states, Time would not exist for us. It thus follows that given an Eternal Changeless Reality, for whom and by whom no "outside world" has been or is manifested; and which is wrapped in an unconscious and dreamless sleep, such as is pictured in the First Aphorism; for such a Reality there could exist no Time—no Time would present itself—Timelessness would abide, until Change began once more.

(18) And in that Moment of Departing, there mpass away Heaven and Earth, Sun, Moon, Stars, and Elements, and thenceforth Time is no more.

(8) Movement Time cannot be- whether a definite act of moving is meant or a united total made up of all such acts- since movement, in either sense, takes place in Time. And, of course, if there is any movement not in Time, the identification with Time becomes all the less tenable.

In a word, Movement must be distinct from the medium in which it takes place.

And, with all that has been said or is still said, one consideration is decisive: Movement can come to rest, can be intermittent; Time is continuous.

We will be told that the Movement of the All is continuous .

But, if the reference is to the Circuit of the heavenly system the time taken in the return path is not that of the outgoing movement; the one is twice as long as the other: this Movement of the All proceeds, therefore, by two different degrees; the rate of the entire journey is not that of the first half.

Further, the fact that we hear of the Movement of the outermost sphere being the swiftest confirms our theory. Obviously, it is the swiftest of movements by taking the lesser time to traverse the greater space the very greatest- all other moving things are slower by taking a longer time to traverse a mere segment of the same extension: in other words, Time is not this movement.

And, if Time is not even the movement of the Kosmic Sphere much less is it the sphere itself though that has been identified with Time on the ground of its being in motion.

Is it, then, some phenomenon or connection of Movement?

Let us, tentatively, suppose it to be extent, or duration, of Movement.

Now, to begin with, Movement, even continuous, has no unchanging extent , since, even in space, it may be faster or slower; there must, therefore, be some unit of standard outside it, by which these differences are measurable, and this outside standard would more properly be called Time. And failing such a measure, which extent would be Time, that of the fast or of the slow- or rather which of them all, since these speed-differences are limitless?

Is it the extent of the subordinate Movement ?

Again, this gives us no unit since the movement is infinitely variable; we would have, thus, not Time but Times.

The extent of the Movement of the All, then?

The Celestial Circuit may, no doubt, be thought of in terms of quantity. It answers to measure- in two ways. First there is space; the movement is commensurate with the area it passes through, and this area is its extent. But this gives us, still, space only, not Time. Secondly, the circuit, considered apart from distance traversed, has the extent of its continuity, of its tendency not to stop but to proceed indefinitely: but this is merely amplitude of Movement; search it, tell its vastness, and, still, Time has no more appeared, no more enters into the matter, than when one certifies a high pitch of heat; all we have discovered is Motion in ceaseless succession, like water flowing ceaselessly, motion and extent of motion.

Succession or repetition gives us Number- dyad, triad, etc.- and the extent traversed is a matter of Magnitude; thus we have Quantity of Movement- in the form of number, dyad, triad, decade, or in the form of extent apprehended in what we may call the amount of the Movement: but, the idea of Time we have not. That definite Quantity is merely something occurring within Time, for, otherwise Time is not everywhere but is something belonging to Movement which thus would be its substratum or basic-stuff: once more, then, we would be making Time identical with Movement; for the extent of Movement is not something outside it but is simply its continuousness, and we need not halt upon the difference between the momentary and the continuous, which is simply one of manner and degree. The extended movement and its extent are not Time; they are in Time. Those that explain Time as extent of Movement must mean not the extent of the movement itself but something which determines its extension, something with which the movement keeps pace in its course. But what this something is, we are not told; yet it is, clearly, Time, that in which all Movement proceeds. This is what our discussion has aimed at from the first: "What, essentially, is Time?" It comes to this: we ask "What is Time?" and we are answered, "Time is the extension of Movement in Time!"

On the one hand Time is said to be an extension apart from and outside that of Movement; and we are left to guess what this extension may be: on the other hand, it is represented as the extension of Movement; and this leaves the difficulty what to make of the extension of Rest- though one thing may continue as long in repose as another in motion, so that we are obliged to think of one thing Time that covers both Rest and Movements, and, therefore, stands distinct from either.

What then is this thing of extension? To what order of beings does it belong?

It obviously is not spatial, for place, too, is something outside it.

(16) If it be urged that Motion is but imperfect Act, there would be no objection to giving priority to Act and subordinating to it Motion with its imperfection as a species: Act would thus be predicated of Motion, but with the qualification "imperfect."

Motion is thought of as imperfect, not because it is not an Act, but because, entirely an Act, it yet entails repetition . It repeats, not in order that it may achieve actuality- it is already actual- but that it may attain a goal distinct from itself and posterior: it is not the motion itself that is then consummated but the result at which it aims. Walking is walking from the outset; when one should traverse a racecourse but has not yet done so, the deficiency lies not in the walking- not in the motion- but in the amount of walking accomplished; no matter what the amount, it is walking and motion already: a moving man has motion and a cutter cuts before there is any question of Quantity. And just as we can speak of Act without implying time, so we can of Motion, except in the sense of motion over a defined area; Act is timeless, and so is Motion pure and simple.

Are we told that Motion is necessarily in time, inasmuch as it involves continuity? But, at this, sight, never ceasing to see, will also be continuous and in time. Our critic, it is true, may find support in that principle of proportion which states that you may make a division of no matter what motion, and find that neither the motion nor its duration has any beginning but that the division may be continued indefinitely in the direction of the motion's origin: this would mean that a motion just begun has been in progress from an infinity of time, that it is infinite as regards its beginning.

Such then is the result of separating Act from Motion: Act, we aver, is timeless; yet we are forced to maintain not only that time is necessary to quantitative motion, but, unreservedly, that Motion is quantitative in its very nature; though indeed, if it were a case of motion occupying a day or some other quantity of time, the exponents of this view would be the first to admit that Quantity is present to Motion only by way of accident.

In sum, just as Act is timeless, so there is no reason why Motion also should not primarily be timeless, time attaching to it only in so far as it happens to have such and such an extension.

Timeless change is sanctioned in the expression, "as if change could not take place all at once"; if then change is timeless, why not Motion also?- Change, be it noted, is here distinguished from the result of change, the result being unnecessary to establish the change itself.

(7) Now comes the question whether, in all this discussion, we are not merely helping to make out a case for some other order of Beings and talking of matters alien to ourselves.

But how could that be? What understanding can there be failing some point of contact? And what contact could there be with the utterly alien?

We must then have, ourselves, some part or share in Eternity.

Still, how is this possible to us who exist in Time?

The whole question turns on the distinction between being in Time and being in Eternity, and this will be best realized by probing to the Nature of Time. We must, therefore, descend from Eternity to the investigation of Time, to the realm of Time: till now we have been taking the upward way; we must now take the downward- not to the lowest levels but within the degree in which Time itself is a descent from Eternity.

If the venerable sages of former days had not treated of Time, our method would be to begin by linking to Eternity its Next , then setting forth the probable nature of such a Next and proceeding to show how the conception thus formed tallies with our own doctrine.

But, as things are, our best beginning is to range over the most noteworthy of the ancient opinions and see whether any of them accord with ours.

Existing explanations of Time seem to fall into three classes:

Time is variously identified with what we know as Movement, with a moved object, and with some phenomenon of Movement: obviously it cannot be Rest or a resting object or any phenomenon of rest, since, in its characteristic idea, it is concerned with change.

Of those that explain it as Movement, some identify it with Absolute Movement , others with that of the All. Those that make it a moved object would identify it with the orb of the All. Those that conceive it as some phenomenon, or some period, of Movement treat it, severally, either as a standard of measure or as something inevitably accompanying Movement, abstract or definite.

(11) It also states: "Time begins." This is seen to be true because Change has begun, and Change is the essence of Time, and Time the measure of Change.

(12) We are brought thus to the conception of a Natural-Principle- Time- a certain expanse of the Life of the Soul, a principle moving forward by smooth and uniform changes following silently upon each other- a Principle, then, whose Act is sequent.

But let us conceive this power of the Soul to turn back and withdraw from the life-course which it now maintains, from the continuous and unending activity of an ever-existent soul not self-contained or self-intent but concerned about doing and engendering: imagine it no longer accomplishing any Act, setting a pause to this work it has inaugurated; let this outgoing phase of the Soul become once more, equally with the rest, turned to the Supreme, to Eternal Being, to the tranquilly stable.

What would then exist but Eternity?

All would remain in unity; how could there be any diversity of things? What Earlier or Later would there be, what long-lasting or short-lasting? What ground would lie ready to the Soul's operation but the Supreme in which it has its Being? Or, indeed, what operative tendency could it have even to That since a prior separation is the necessary condition of tendency?

The very sphere of the Universe would not exist; for it cannot antedate Time: it, too, has its Being and its Movement in Time; and if it ceased to move, the Soul-Act continuing, we could measure the period of its Repose by that standard outside it.

If, then, the Soul withdrew, sinking itself again into its primal unity, Time would disappear: the origin of Time, clearly, is to be traced to the first stir of the Soul's tendency towards the production of the sensible universe with the consecutive act ensuing. This is how "Time"- as we read- "came into Being simultaneously" with this All: the Soul begot at once the Universe and Time; in that activity of the Soul this Universe sprang into being; the activity is Time, the Universe is a content of Time. No doubt it will be urged that we read also of the orbit of the Stars being Times": but do not forget what follows; "the stars exist," we are told, "for the display and delimitation of Time," and "that there may be a manifest Measure." No indication of Time could be derived from the Soul; no portion of it can be seen or handled, so it could not be measured in itself, especially when there was as yet no knowledge of counting; therefore the Soul brings into being night and day; in their difference is given Duality- from which, we read, arises the concept of Number.

We observe the tract between a sunrise and its return and, as the movement is uniform, we thus obtain a Time-interval upon which to measure ourselves, and we use this as a standard. We have thus a measure of Time. Time itself is not a measure. How would it set to work? And what kind of thing is there of which it could say, "I find the extent of this equal to such and such a stretch of my own extent?" What is this "I"? Obviously something by which measurement is known. Time, then, serves towards measurement but is not itself the Measure: the Movement of the All will be measured according to Time, but Time will not, of its own Nature, be a Measure of Movement: primarily a Kind to itself, it will incidentally exhibit the magnitudes of that movement.

And the reiterated observation of Movement- the same extent found to be traversed in such and such a period- will lead to the conception of a definite quantity of Time past.

This brings us to the fact that, in a certain sense, the Movement, the orbit of the universe, may legitimately be said to measure Time- in so far as that is possible at all- since any definite stretch of that circuit occupies a certain quantity of Time, and this is the only grasp we have of Time, our only understanding of it: what that circuit measures- by indication, that is- will be Time, manifested by the Movement but not brought into being by it.

This means that the measure of the Spheric Movement has itself been measured by a definite stretch of that Movement and therefore is something different; as measure, it is one thing and, as the measured, it is another; its being measured cannot be of its essence.

We are no nearer knowledge than if we said that the foot-rule measures Magnitude while we left the concept Magnitude undefined; or, again, we might as well define Movement- whose limitlessness puts it out of our reach- as the thing measured by Space; the definition would be parallel since we can mark off a certain space which the Movement has traversed and say the one is equivalent to the other.

(39) Timaeus: that the “wanderings“ of these bodies, which are hard to calculate and of wondrous complexity, constitute Time. Nevertheless, it is still quite possible to perceive that the complete number of Time fulfils the Complete Year when all the eight circuits, with their relative speeds, finish together and come to a head, when measured by the revolution of the Same and Similarly-moving. In this wise and for these reasons were generated all those stars which turn themselves about as they travel through Heaven, to the end that this Universe might be as similar as possible to the perfect and intelligible Living Creature in respect of its imitation of the Eternal

(11) To this end we must go back to the state we affirmed of Eternity, unwavering Life, undivided totality, limitless, knowing no divagation, at rest in unity and intent upon it. Time was not yet: or at least it did not exist for the Eternal Beings, though its being was implicit in the Idea and Principle of progressive derivation.

But from the Divine Beings thus at rest within themselves, how did this Time first emerge?

We can scarcely call upon the Muses to recount its origin since they were not in existence then- perhaps not even if they had been. The engendered thing, Time, itself, can best tell us how it rose and became manifest; something thus its story would run:

Time at first- in reality before that "first" was produced by desire of succession- Time lay, self-concentrated, at rest within the Authentic Existent: it was not yet Time; it was merged in the Authentic and motionless with it. But there was an active principle there, one set on governing itself and realizing itself , and it chose to aim at something more than its present: it stirred from its rest, and Time stirred with it. And we, stirring to a ceaseless succession, to a next, to the discrimination of identity and the establishment of ever-new difference, traversed a portion of the outgoing path and produced an image of Eternity, produced Time.

For the Soul contained an unquiet faculty, always desirous of translating elsewhere what it saw in the Authentic Realm, and it could not bear to retain within itself all the dense fullness of its possession.

A Seed is at rest; the nature-principle within, uncoiling outwards, makes way towards what seems to it a large life; but by that partition it loses; it was a unity self-gathered, and now, in going forth from itself, it fritters its unity away; it advances into a weaker greatness. It is so with this faculty of the Soul, when it produces the Kosmos known to sense- the mimic of the Divine Sphere, moving not in the very movement of the Divine but in its similitude, in an effort to reproduce that of the Divine. To bring this Kosmos into being, the Soul first laid aside its eternity and clothed itself with Time; this world of its fashioning it then gave over to be a servant to Time, making it at every point a thing of Time, setting all its progressions within the bournes of Time. For the Kosmos moves only in Soul- the only Space within the range of the All open to it to move in- and therefore its Movement has always been in the Time which inheres in Soul.

Putting forth its energy in act after act, in a constant progress of novelty, the Soul produces succession as well as act; taking up new purposes added to the old it brings thus into being what had not existed in that former period when its purpose was still dormant and its life was not as it since became: the life is changed and that change carries with it a change of Time. Time, then, is contained in differentiation of Life; the ceaseless forward movement of Life brings with it unending Time; and Life as it achieves its stages constitutes past Time.

Would it, then, be sound to define Time as the Life of the Soul in movement as it passes from one stage of act or experience to another?

Yes; for Eternity, we have said, is Life in repose, unchanging, self-identical, always endlessly complete; and there is to be an image of Eternity-Time- such an image as this lower All presents of the Higher Sphere. Therefore over against that higher life there must be another life, known by the same name as the more veritable life of the Soul; over against that movement of the Intellectual Soul there must be the movement of some partial phase; over against that identity, unchangeableness and stability there must be that which is not constant in the one hold but puts forth multitudinous acts; over against that oneness without extent or interval there must be an image of oneness, a unity of link and succession; over against the immediately infinite and all-comprehending, that which tends, yes, to infinity but by tending to a perpetual futurity; over against the Whole in concentration, there must be that which is to be a Whole by stages never final. The lesser must always be working towards the increase of its Being, this will be its imitation of what is immediately complete, self-realized, endless without stage: only thus can its Being reproduce that of the Higher.

Time, however, is not to be conceived as outside of Soul; Eternity is not outside of the Authentic Existent: nor is it to be taken as a sequence or succession to Soul, any more than Eternity is to the Divine. It is a thing seen upon Soul, inherent, coeval to it, as Eternity to the Intellectual Realm.

(12) Just as the present aeon, though a unity, is divided by units of time and units of time are divided into years and years are divided into seasons and seasons into months, and months into days, and days into hours, and hours into moments, so too the aeon of the Truth, since it is a unity and multiplicity, receives honor in the small and the great names according to the power of each to grasp it - by way of analogy - like a spring which is what it is, yet flows into streams and lakes and canals and branches, or like a root spread out beneath trees and branches with its fruit, or like a human body, which is partitioned in an indivisible way into members of members, primary members and secondary, great and small.

(9) "A Number, a Measure, belonging to Movement?"

This, at least, is plausible since Movement is a continuous thin; but let us consider.

To begin with, we have the doubt which met us when we probed its identification with extent of Movement: is Time the measure of any and every Movement?

Have we any means of calculating disconnected and lawless Movement? What number or measure would apply? What would be the principle of such a Measure?

One Measure for movement slow and fast, for any and every movement: then that number and measure would be like the decade, by which we reckon horses and cows, or like some common standard for liquids and solids. If Time is this Kind of Measure, we learn, no doubt, of what objects it is a Measure- of Movements- but we are no nearer understanding what it is in itself.

Or: we may take the decade and think of it, apart from the horses or cows, as a pure number; this gives us a measure which, even though not actually applied, has a definite nature. Is Time, perhaps, a Measure in this sense?

No: to tell us no more of Time in itself than that it is such a number is merely to bring us back to the decade we have already rejected, or to some similar collective figure.

If, on the other hand, Time is a Measure possessing a continuous extent of its own, it must have quantity, like a foot-rule; it must have magnitude: it will, clearly, be in the nature of a line traversing the path of Movement. But, itself thus sharing in the movement, how can it be a Measure of Movement? Why should the one of the two be the measure rather than the other? Besides an accompanying measure is more plausibly considered as a measure of the particular movement it accompanies than of Movement in general. Further, this entire discussion assumes continuous movement, since the accompanying principle; Time, is itself unbroken .

The fact is that we are not to think of a measure outside and apart, but of a combined thing, a measured Movement, and we are to discover what measures it.

Given a Movement measured, are we to suppose the measure to be a magnitude?

If so, which of these two would be Time, the measured movement or the measuring magnitude? For Time must be either the movement measured by magnitude, or the measuring magnitude itself or something using the magnitude like a yard-stick to appraise the movement. In all three cases, as we have indicated, the application is scarcely plausible except where continuous movement is assumed: unless the Movement proceeds smoothly, and even unintermittently and as embracing the entire content of the moving object, great difficulties arise in the identification of Time with any kind of measure.

Let us, then, suppose Time to be this "measured Movement," measured by quantity. Now the Movement if it is to be measured requires a measure outside itself; this was the only reason for raising the question of the accompanying measure. In exactly the same way the measuring magnitude, in turn, will require a measure, because only when the standard shows such and such an extension can the degree of movement be appraised. Time then will be, not the magnitude accompanying the Movement, but that numerical value by which the magnitude accompanying the Movement is estimated. But that number can be only the abstract figure which represents the magnitude, and it is difficult to see how an abstract figure can perform the act of measuring.

And, supposing that we discover a way in which it can, we still have not Time, the measure, but a particular quantity of Time, not at all the same thing: Time means something very different from any definite period: before all question as to quantity is the question as to the thing of which a certain quantity is present.

Time, we are told, is the number outside Movement and measuring it, like the tens applied to the reckoning of the horses and cows but not inherent in them: we are not told what this Number is; yet, applied or not, it must, like that decade, have some nature of its own.

Or "it is that which accompanies a Movement and measures it by its successive stages"; but we are still left asking what this thing recording the stages may be.

In any case, once a thing- whether by point or standard or any other means- measures succession, it must measure according to time: this number appraising movement degree by degree must, therefore, if it is to serve as a measure at all, be something dependent upon time and in contact with it: for, either, degree is spatial, merely- the beginning and end of the Stadium, for example- or in the only alternative, it is a pure matter of Time: the succession of early and late is stage of Time, Time ending upon a certain Now or Time beginning from a Now.

Time, therefore, is something other than the mere number measuring Movement, whether Movement in general or any particular tract of Movement.

Further: Why should the mere presence of a number give us Time- a number measuring or measured; for the same number may be either- if Time is not given us by the fact of Movement itself, the Movement which inevitably contains in itself a succession of stages? To make the number essential to Time is like saying that magnitude has not its full quantity unless we can estimate that quantity.

Again, if Time is, admittedly, endless, how can number apply to it?

Are we to take some portion of Time and find its numerical statement? That simply means that Time existed before number was applied to it.

We may, therefore, very well think that it existed before the Soul or Mind that estimates it- if, indeed, it is not to be thought to take its origin from the Soul- for no measurement by anything is necessary to its existence; measured or not, it has the full extent of its being.

And suppose it to be true that the Soul is the appraiser, using Magnitude as the measuring standard, how does this help us to the conception of Time?

(18) These salutary revolutions, in accordance with the order of change, are distinguished both by times, and places, and honours, and cognitions, and heritages, and ministries, according to the particular order of each change, up to the transcendent and continual contemplation of the Lord in eternity.

(13) The Spheral Circuit, then, performed in Time, indicates it: but when we come to Time itself there is no question of its being "within" something else: it must be primary, a thing "within itself." It is that in which all the rest happens, in which all movement and rest exist smoothly and under order; something following a definite order is necessary to exhibit it and to make it a subject of knowledge- though not to produce it- it is known by order whether in rest or in motion; in motion especially, for Movement better moves Time into our ken than rest can, and it is easier to estimate distance traversed than repose maintained.

This last fact has led to Time being called a measure of Movement when it should have been described as something measured by Movement and then defined in its essential nature; it is an error to define it by a mere accidental concomitant and so to reverse the actual order of things. Possibly, however, this reversal was not intended by the authors of the explanation: but, at any rate, we do not understand them; they plainly apply the term Measure to what is in reality the measured and leave us unable to grasp their meaning: our perplexity may be due to the fact that their writings- addressed to disciples acquainted with their teaching- do not explain what this thing, measure, or measured object, is in itself.

Plato does not make the essence of Time consist in its being either a measure or a thing measured by something else.

Upon the point of the means by which it is known, he remarks that the Circuit advances an infinitesimal distance for every infinitesimal segment of Time so that from that observation it is possible to estimate what the Time is, how much it amounts to: but when his purpose is to explain its essential nature he tells us that it sprang into Being simultaneously with the Heavenly system, a reproduction of Eternity, its image in motion, Time necessarily unresting as the Life with which it must keep pace: and "coeval with the Heavens" because it is this same Life which brings the Heavens also into being; Time and the Heavens are the work of the one Life.

Suppose that Life, then, to revert- an impossibility- to perfect unity: Time, whose existence is in that Life, and the Heavens, no longer maintained by that Life, would end at once.

It is the height of absurdity to fasten on the succession of earlier and later occurring in the life and movement of this sphere of ours, to declare that it must be some definite thing and to call it Time, while denying the reality of the more truly existent Movement, that of the Soul, which has also its earlier and later: it cannot be reasonable to recognize succession in the case of the Soulless Movement- and so to associate Time with that- while ignoring succession and the reality of Time in the Movement from which the other takes its imitative existence; to ignore, that is, the very Movement in which succession first appears, a self-actuated movement which, engendering its own every operation, is the source of all that follows upon itself, to all which, it is the cause of existence, at once, and of every consequent.

But:- we treat the Kosmic Movement as overarched by that of the Soul and bring it under Time; yet we do not set under Time that Soul-Movement itself with all its endless progression: what is our explanation of this paradox?

Simply, that the Soul-Movement has for its Prior Eternity which knows neither its progression nor its extension. The descent towards Time begins with this Soul-Movement; it made Time and harbours Time as a concomitant to its Act.

And this is how Time is omnipresent: that Soul is absent from no fragment of the Kosmos just as our Soul is absent from no particle of ourselves. As for those who pronounce Time a thing of no substantial existence, of no reality, they clearly belie God Himself whenever they say "He was" or "He will be": for the existence indicated by the "was and will be" can have only such reality as belongs to that in which it is said to be situated:- but this school demands another type of argument.

Meanwhile we have a supplementary observation to make.

Take a man walking and observe the advance he has made; that advance gives you the quantity of movement he is employing: and when you know that quantity- represented by the ground traversed by his feet, for, of course, we are supposing the bodily movement to correspond with the pace he has set within himself- you know also the movement that exists in the man himself before the feet move.

You must relate the body, carried forward during a given period of Time, to a certain quantity of Movement causing the progress and to the Time it takes, and that again to the Movement, equal in extension, within the man's soul.

But the Movement within the Soul- to what are you to (relate) refer that?

Let your choice fall where it may, from this point there is nothing but the unextended: and this is the primarily existent, the container to all else, having itself no container, brooking none.

And, as with Man's Soul, so with the Soul of the All.

"Is Time, then, within ourselves as well?"

Time in every Soul of the order of the All-Soul, present in like form in all; for all the Souls are the one Soul.

And this is why Time can never be broken apart, any more than Eternity which, similarly, under diverse manifestations, has its Being as an integral constituent of all the eternal Existences.

(3) The species, then, persists, as frequently producing from itself as many images, and as diverse, as there are moments in the Cosmic Revolution, —a Cosmos which doth [ever] change in revolution. But the idea [itself] is neither changed nor turned. So are the forms of every single genus permanent, [and yet] dissimilar in the same [general] form. XXXVI

(22) But suppose that we identify alteration with Motion on the ground that Motion itself results in difference: how then do we proceed to define Motion?

It may roughly be characterized as the passage from the potentiality to its realization. That is potential which can either pass into a Form- for example, the potential statue- or else pass into actuality- such as the ability to walk: whenever progress is made towards the statue, this progress is Motion; and when the ability to walk is actualized in walking, this walking is itself Motion: dancing is, similarly, the motion produced by the potential dancer taking his steps.

In the one type of Motion a new Form comes into existence created by the motion; the other constitutes, as it were, the pure Form of the potentiality, and leaves nothing behind it when once the motion has ceased. Accordingly, the view would not be unreasonable which, taking some Forms to be active, others inactive, regarded Motion as a dynamic Form in opposition to the other Forms which are static, and further as the cause of whatever new Form ensues upon it. To proceed to identify this bodily motion with life would however be unwarrantable; it must be considered as identical only in name with the motions of Intellect and Soul.

That Motion is a genus we may be all the more confident in virtue of the difficulty- the impossibility even- of confining it within a definition.

But how can it be a Form in cases where the motion leads to deterioration, or is purely passive? Motion, we may suggest, is like the heat of the sun causing some things to grow and withering others. In so far as Motion is a common property, it is identical in both conditions; its apparent difference is due to the objects moved.

Is, then, becoming ill identical with becoming well? As motions they are identical. In what respect, then, do they differ? In their substrates? or is there some other criterion?

This question may however be postponed until we come to consider alteration: at present we have to discover what is the constant element in every motion, for only on this basis can we establish the claim of Motion to be a genus.

Perhaps the one term covers many meanings; its claim to generic status would then correspond to that of Being.

As a solution of the problem we may suggest that motions conducing to the natural state or functioning in natural conditions should perhaps, as we have already asserted, be regarded as being in a sense Forms, while those whose direction is contrary to nature must be supposed to be assimilated to the results towards which they lead.

But what is the constant element in alteration, in growth and birth and their opposites, in local change? What is that which makes them all motions? Surely it is the fact that in every case the object is never in the same state before and after the motion, that it cannot remain still and in complete inactivity but, so long as the motion is present, is continually urged to take a new condition, never acquiescing in Identity but always courting Difference; deprived of Difference, Motion perishes.

Thus, Difference may be predicated of Motion, not merely in the sense that it arises and persists in a difference of conditions, but in the sense of being itself perpetual difference. It follows that Time, as being created by Motion, also entails perpetual difference: Time is the measure of unceasing Motion, accompanying its course and, as it were, carried along its stream.

In short, the common basis of all Motion is the existence of a progression and an urge from potentiality and the potential to actuality and the actual: everything which has any kind of motion whatsoever derives this motion from a pre-existent potentiality within itself of activity or passivity.

(11) When one is so far advanced that every shadow and every echo has disappeared, so that one is quite quiet and firm, it is safe within the cave of power, where all that is miraculous returns to its roots. The place is not changed but divides itself. It is incorporeal space where a thousand and ten thousand places are one place. The time is not changed, but divides itself. It is immeasurable time when all the aeons are like a moment.

Now if the body of the All
