What, then, is time? There is no quick and easy answer to this, for it is no simple matter to understand what time is, let alone find words to explain it. Yet in our conversation, no word is more familiar to us, or more easily recognised, than the word ‘time’. We definitely understand what this word means, both when we use it ourselves and when we hear it used by others.
What, then, is time? I know perfectly well what it is – so long as no one asks me; but as soon as I am asked what it is and try to explain it, I am nonplussed. However, I can say with confidence that if nothing passed, there would be no past time; if nothing were going to happen, there would be no future time; and if nothing were, there would be no present time.
So with these three divisions of time, how can two of them – the past and the future – be, when the past no longer is, and the future is not yet? As for the present, if it were always present and never moved on to become the past, it would not be time but eternity. Therefore, if the present is time only because of the fact that it moves on to become the past, how can we say that even the present is, when the reason why it is is that it is not to be? In other words, we cannot properly say that time exists, except because of its impending state of nonexistence.

AUGUSTINE: You who wish to know, do you know that you exist?
REASON: I do.
A: How do you know this?
R: I do not know.
A: Do you feel yourself to be simple or complex?
R: I do not know.
A: Do you feel that you are self-moved?
R: I do not know.
A: Do you know that you think?
R: I do.

With regard to these truths, I am not afraid of any arguments put forward by the Academics. If they say, ‘What if you are mistaken?’ I reply, ‘Even if I am mistaken, I still exist.’ A nonexistent being cannot be mistaken. Therefore I must exist if I am mistaken. Since my being mistaken proves that I exist, how can I be mistaken when I think that I exist, if my mistake confirms my existence? Therefore I must exist in order to be mistaken, then, even if I am mistaken, there is no denying that I am not mistaken in my knowledge that I exist. Therefore I am also not mistaken in knowing that I know. For in the same way that I know I exist, I also know that I know. And when I am glad about these two facts, I can add with equal certainty the fact of that gladness to the things that I know. For I am not mistaken about the fact of my gladness, because I am not mistaken about the things which I love. Even if these things are illusory, it would still be a fact that I love the illusions.
