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.
