The Confessions: Chapter XVII

Chapter XVII.—Nevertheless There is Time Past and Future.

2. I ask, Father, I do not affirm. O my God, rule and guide me. “Who is there who can say to me that there are not three times (as we learned when boys, and as we have taught boys), the past, present, and future, but only present, because these two are not? Or are they also; but when from future it becometh present, cometh it forth from some secret place, and when from the present it becometh past, doth it retire into anything secret? For where have they, who have foretold future things, seen these things, if as yet they are not? For that which is not cannot be seen. And they who relate things past could not relate them as true, did they not perceive them in their mind. Which things, if they were not, they could in no wise be discerned. There are therefore things both future and past.
