Permit me, Lord, to seek further. O my hope, let not my purpose be confounded. For if times past and to come be, I would know where they be. Which yet if I cannot, yet I know, wherever they be, they are not there as future, or past, but present. For if there also they be future, they are not yet there; if there also they be past, they are no longer there. Wheresoever then is whatsoever is, it is only as present. Although when past facts are related, there are drawn out of the memory, not the things themselves which are past, but words which, conceived by the images of the things, they, in passing, have through the senses left as traces in the mind. Thus my childhood, which now is not, is in time past, which now is not: but now when I recall its image, and tell of it, I behold it in the present, because it is still in my memory. Whether there be a like cause of foretelling things to come also; that of things which as yet are not, the images may be perceived before, already existing, I confess, O my God, I know not. This indeed I know, that we generally think before on our future actions, and that that forethinking is present, but the action whereof we forethink is not yet, because it is to come. Which, when we have set upon, and have begun to do what we were forethinking, then shall that action be; because then it is no longer future, but present.
Which way soever then this secret fore-perceiving of things to come be; that only can be seen, which is. But what now is, is not future, but present. When then things to come are said to be seen, it is not themselves which as yet are not (that is, which are to be), but their causes perchance or signs are seen, which already are. Therefore they are not future but present to those who now see that, from which the future, being foreconceived in the mind, is foretold. Which fore-conceptions again now are; and those who foretell those things, do behold the conceptions present before them. Let now the numerous variety of things furnish me some example. I behold the day-break, I foreshow, that the sun, is about to rise. What I behold, is present; what I foresignify, to come; not the sun, which already is; but the sun-rising, which is not yet. And yet did I not in my mind imagine the sun-rising itself (as now while I speak of it), I could not foretell it. But neither is that day-break which I discern in the sky, the sun-rising, although it goes before it; nor that imagination of my mind; which two are seen now present, that the other which is to be may be foretold. Future things then are not yet: and if they be not yet, they are not: and if they are not, they cannot be seen; yet foretold they may be from things present, which are already, and are seen.
Thou then, Ruler of Thy creation, by what way dost Thou teach souls things to come? For Thou didst teach Thy Prophets. By what way dost Thou, to whom nothing is to come, teach things to come; or rather of the future, dost teach things present? For, what is not, neither can it be taught. Too far is this way of my ken: it is too mighty for me, I cannot attain unto it; but from Thee I can, when Thou shalt vouchsafe it, O sweet light of my hidden eyes.
What now is clear and plain is, that neither things to come nor past are. Nor is it properly said, "there be three times, past, present, and to come": yet perchance it might be properly said, "there be three times; a present of things past, a present of things present, and a present of things future." For these three do exist in some sort, in the soul, but otherwhere do I not see them; present of things past, memory; present of things present, sight; present of things future, expectation. If thus we be permitted to speak, I see three times, and I confess there are three. Let it be said too, "there be three times, past, present, and to come": in our incorrect way. See, I object not, nor gainsay, nor find fault, if what is so said be but understood, that neither what is to be, now is, nor what is past. For but few things are there, which we speak properly, most things improperly; still the things intended are understood.
I said then even now, we measure times as they pass, in order to be able to say, this time is twice so much as that one; or, this is just so much as that; and so of any other parts of time, which be measurable. Wherefore, as I said, we measure times as they pass. And if any should ask me, "How knowest thou?" I might answer, "I know, that we do measure, nor can we measure things that are not; and things past and to come, are not." But time present how do we measure, seeing it hath no space? It is measured while passing, but when it shall have passed, it is not measured; for there will be nothing to be measured. But whence, by what way, and whither passes it while it is a measuring? whence, but from the future? Which way, but through the present? whither, but into the past? From that therefore, which is not yet, through that, which hath no space, into that, which now is not. Yet what do we measure, if not time in some space? For we do not say, single, and double, and triple, and equal, or any other like way that we speak of time, except of spaces of times. In what space then do we measure time passing? In the future, whence it passeth through? But what is not yet, we measure not. Or in the present, by which it passes? but no space, we do not measure: or in the past, to which it passes? But neither do we measure that, which now is not.
My soul is on fire to know this most intricate enigma. Shut it not up, O Lord my God, good Father; through Christ I beseech Thee, do not shut up these usual, yet hidden things, from my desire, that it be hindered from piercing into them; but let them dawn through Thy enlightening mercy, O Lord. Whom shall I enquire of concerning these things? and to whom shall I more fruitfully confess my ignorance, than to Thee, to Whom these my studies, so vehemently kindled toward Thy Scriptures, are not troublesome? Give what I love; for I do love, and this hast Thou given me. Give, Father, Who truly knowest to give good gifts unto Thy children. Give, because I have taken upon me to know, and trouble is before me until Thou openest it. By Christ I beseech Thee, in His Name, Holy of holies, let no man disturb me. For I believed, and therefore do I speak. This is my hope, for this do I live, that I may contemplate the delights of the Lord. Behold, Thou hast made my days old, and they pass away, and how, I know not. And we talk of time, and time, and times, and times, "How long time is it since he said this"; "how long time since he did this"; and "how long time since I saw that"; and "this syllable hath double time to that single short syllable." These words we speak, and these we hear, and are understood, and understand. Most manifest and ordinary they are, and the self-same things again are but too deeply hidden, and the discovery of them were new.
I heard once from a learned man, that the motions of the sun, moon, and stars, constituted time, and I assented not. For why should not the motions of all bodies rather be times? Or, if the lights of heaven should cease, and a potter's wheel run round, should there be no time by which we might measure those whirlings, and say, that either it moved with equal pauses, or if it turned sometimes slower, otherwhiles quicker, that some rounds were longer, other shorter? Or, while we were saying this, should we not also be speaking in time? Or, should there in our words be some syllables short, others long, but because those sounded in a shorter time, these in a longer? God, grant to men to see in a small thing notices common to things great and small. The stars and lights of heaven, are also for signs, and for seasons, and for years, and for days; they are; yet neither should I say, that the going round of that wooden wheel was a day, nor yet he, that it was therefore no time.
I desire to know the force and nature of time, by which we measure the motions of bodies, and say (for example) this motion is twice as long as that. For I ask, Seeing "day" denotes not the stay only of the sun upon the earth (according to which day is one thing, night another); but also its whole circuit from east to east again; according to which we say, "there passed so many days," the night being included when we say, "so many days," and the nights not reckoned apart;—seeing then a day is completed by the motion of the sun and by his circuit from east to east again, I ask, does the motion alone make the day, or the stay in which that motion is completed, or both? For if the first be the day; then should we have a day, although the sun should finish that course in so small a space of time, as one hour comes to. If the second, then should not that make a day, if between one sun-rise and another there were but so short a stay, as one hour comes to; but the sun must go four and twenty times about, to complete one day. If both, then neither could that be called a day; if the sun should run his whole round in the space of one hour; nor that, if, while the sun stood still, so much time should overpass, as the sun usually makes his whole course in, from morning to morning. I will not therefore now ask, what that is which is called day; but, what time is, whereby we, measuring the circuit of the sun, should say that it was finished in half the time it was wont, if so be it was finished in so small a space as twelve hours; and comparing both times, should call this a single time, that a double time; even supposing the sun to run his round from east to east, sometimes in that single, sometimes in that double time. Let no man then tell me, that the motions of the heavenly bodies constitute times, because, when at the prayer of one, the sun had stood still, till he could achieve his victorious battle, the sun stood still, but time went on. For in its own allotted space of time was that battle waged and ended. I perceive time then to be a certain extension. But do I perceive it, or seem to perceive it? Thou, Light and Truth, wilt show me.
Dost Thou bid me assent, if any define time to be "motion of a body?" Thou dost not bid me. For that no body is moved, but in time, I hear; this Thou sayest; but that the motion of a body is time, I hear not; Thou sayest it not. For when a body is moved, I by time measure, how long it moveth, from the time it began to move until it left off? And if I did not see whence it began; and it continue to move so that I see not when it ends, I cannot measure, save perchance from the time I began, until I cease to see. And if I look long, I can only pronounce it to be a long time, but not how long; because when we say "how long," we do it by comparison; as, "this is as long as that," or "twice so long as that," or the like. But when we can mark the distances of the places, whence and whither goeth the body moved, or his parts, if it moved as in a lathe, then can we say precisely, in how much time the motion of that body or his part, from this place unto that, was finished. Seeing therefore the motion of a body is one thing, that by which we measure how long it is, another; who sees not, which of the two is rather to be called time? For and if a body be sometimes moved, sometimes stands still, then we measure, not his motion only, but his standing still too by time; and we say, "it stood still, as much as it moved"; or "it stood still twice or thrice so long as it moved"; or any other space which our measuring hath either ascertained, or guessed; more or less, as we use to say. Time then is not the motion of a body.
And I confess to Thee, O Lord, that I yet know not what time is, and again I confess unto Thee, O Lord, that I know that I speak this in time, and that having long spoken of time, that very "long" is not long, but by the pause of time. How then know I this, seeing I know not what time is? or is it perchance that I know not how to express what I know? Woe is me, that do not even know, what I know not. Behold, O my God, before Thee I lie not; but as I speak, so is my heart. Thou shalt light my candle; Thou, O Lord my God, wilt enlighten my darkness.
