Does not my soul most truly confess unto Thee, that I do measure times? Do I then measure, O my God, and know not what I measure? I measure the motion of a body in time; and the time itself do I not measure? Or could I indeed measure the motion of a body how long it were, and in how long space it could come from this place to that, without measuring the time in which it is moved? This same time then, how do I measure? do we by a shorter time measure a longer, as by the space of a cubit, the space of a rood? for so indeed we seem by the space of a short syllable, to measure the space of a long syllable, and to say that this is double the other. Thus measure we the spaces of stanzas, by the spaces of the verses, and the spaces of the verses, by the spaces of the feet, and the spaces of the feet, by the spaces of the syllables, and the spaces of long, by the space of short syllables; not measuring by pages (for then we measure spaces, not times); but when we utter the words and they pass by, and we say "it is a long stanza, because composed of so many verses; long verses, because consisting of so many feet; long feet, because prolonged by so many syllables; a long syllable because double to a short one. But neither do we this way obtain any certain measure of time; because it may be, that a shorter verse, pronounced more fully, may take up more time than a longer, pronounced hurriedly. And so for a verse, a foot, a syllable. Whence it seemed to me, that time is nothing else than protraction; but of what, I know not; and I marvel, if it be not of the mind itself? For what, I beseech Thee, O my God, do I measure, when I say, either indefinitely "this is a longer time than that," or definitely "this is double that"? That I measure time, I know; and yet I measure not time to come, for it is not yet; nor present, because it is not protracted by any space; nor past, because it now is not. What then do I measure? Times passing, not past? for so I said.
