Chapter XXVII.—Times are Measured in Proportion as They Pass by.
34. Persevere, O my mind, and give earnest heed. od is our helper; He made us, and not we ourselves. 1052 Give heed, where truth dawns. Lo, suppose the voice of a body begins to sound, and does sound, and sounds on, and lo! it ceases,—it is now silence, and that voice is past and is no longer a voice. It was future before it sounded, and could not be measured, because as yet it was not; and now it cannot, because it no longer is. Then, therefore, while it was sounding, it might, because there was then that which might be measured. But even then it did not stand still, for it was going and passing away. Could it, then, on that account be measured the more? For, while passing, it was being extended into some space of time, in which it might be measured, since the present hath no space. If, therefore, then it might be measured, lo! suppose another voice hath begun to sound, and still soundeth, in a continued tenor without any interruption, we can measure it while it is sounding; for when it shall have ceased to sound, it will be already past, and there will not be that which can be measured. Let us measure it truly, and let us say how much it is. But as yet it sounds, nor can it be measured, save from that instant in which it began to sound, even to the end in which it left off. For the interval itself we measure from p. 173 some beginning unto some end. On which account, a voice which is not yet ended cannot be measured, so that it may be said how long or how short it may be; nor can it be said to be equal to another, or single or double in respect of it, or the like. But when it is ended, it no longer is. In what manner, therefore, may it be measured? And yet we measure times; still not those which as yet are not, nor those which no longer are, nor those which are protracted by some delay, nor those which have no limits. We, therefore, measure neither future times, nor past, nor present, nor those passing by; and yet we do measure times.
35. Deus Creator omnium; this verse of eight syllables alternates between short and long syllables. The four short, then, the first, third, fifth and seventh, are single in respect of the four long, the second, fourth, sixth, and eighth. Each of these hath a double time to every one of those. I pronounce them, report on them, and thus it is, as is perceived by common sense. By common sense, then, I measure a long by a short syllable, and I find that it has twice as much. But when one sounds after another, if the former be short the latter long, how shall I hold the short one, and how measuring shall I apply it to the long, so that I may find out that this has twice as much, when indeed the long does not begin to sound unless the short leaves off sounding? That very long one I measure not as present, since I measure it not save when ended. But its ending is its passing away. What, then, is it that I can measure? Where is the short syllable by which I measure? Where is the long one which I measure? Both have sounded, have flown, have passed away, and are no longer; and still I measure, and I confidently answer (so far as is trusted to a practised sense), that as to space of time this syllable is single, that double. Nor could I do this, unless because they have past, and are ended. Therefore do I not measure themselves, which now are not, but something in my memory, which remains fixed.
36. In thee, O my mind, I measure times. 1053 Do not overwhelm me with thy clamour. That is, do not overwhelm thyself with the multitude of thy impressions. In thee, I say, I measure times; the impression which things as they pass by make on thee, and which, when they have passed by, remains, that I measure as time present, not those things which have passed by, that the impression should be made. This I measure when I measure times. Either, then, these are times, or I do not measure times. What when we measure silence, and say that this silence hath lasted as long as that voice lasts? Do we not extend our thought to the measure of a voice, as if it sounded, so that we may be able to declare something concerning the intervals of silence in a given space of time? For when both the voice and tongue are still, we go over in thought poems and verses, and any discourse, or dimensions of motions; and declare concerning the spaces of times, how much this may be in respect of that, not otherwise than if uttering them we should pronounce them. Should any one wish to utter a lengthened sound, and had with forethought determined how long it should be, that man hath in silence verily gone through a space of time, and, committing it to memory, he begins to utter that speech, which sounds until it be extended to the end proposed; truly it hath sounded, and will sound. For what of it is already finished hath verily sounded, but what remains will sound; and thus does it pass on, until the present intention carry over the future into the past; the past increasing by the diminution of the future, until, by the consumption of the future, all be past.
With the argument in this and the previous sections, compare Dr. Reids remarks in his Intellectual Powers, iii. 5: “We may measure duration by the succession of thoughts in the mind, as we measure length by inches or feet, but the notion or idea of duration must be antecedent to the mensuration of it, as the notion of length is antecedent to its being measured.…Reason, from the contemplation of finite extended things, leads us necessarily to the belief of an immensity that contains them. In like manner, memory gives us the conception and belief of finite intervals of duration. From the contemplation of these, reason leads us necessarily to the belief of an eternity, which comprehends all things that have a beginning and an end.” The student will with advantage examine a monograph on this subject by C. Fortlage, entitled, Aurelii Augustini doctrina de tempore ex libro xi. Confessionum depromta, Aristotelicæ, Kantianæ, aliarumque theoriarium recensione aucta, et congruis hodiernæ philosophiæ ideis amplificata (Heidelbergæ, 1836). He says that amongst all the philosophers none have so nearly approached truth as Augustin.
