Chapter 18. Past and Future Times Cannot Be Thought of But as Present.
23. Allow me, O Lord, to seek further; O my Hope, let not my purpose be confounded. For if there are times past and future, I desire to know where they are. But if as yet I do not succeed, I still know, wherever they are, that they are not there as future or past, but as present. For if there also they be future, they are not as yet there; if even there they be past, they are no longer there. Wheresoever, therefore, they are, whatsoever they are, they are only so as present. Although past things are related as true, they are drawn out from the memory,— not the things themselves, which have passed, but the words conceived from the images of the things which they have formed in the mind as footprints in their passage through the senses. My childhood, indeed, which no longer is, is in time past, which now is not; but when I call to mind its image, and speak of it, I behold it in the present, because it is as yet in my memory. Whether there be a like cause of foretelling future things, that of things which as yet are not the images may be perceived as already existing, I confess, my God, I know not. This certainly I know, that we generally think before on our future actions, and that this premeditation is present; but that the action whereon we premeditate is not yet, because it is future; which when we shall have entered upon, and have begun to do that which we were premeditating, then shall that action be, because then it is not future, but present.
