Quote:For what is time? Who can easily and briefly explain it? Who even in thought can comprehend it, even to the pronouncing of a word concerning it? But what in speaking do we refer to more familiarly and knowingly than time? And certainly we understand when we speak of it; we understand also when we hear it spoken of by another. What, then, is time? If no one ask of me, I know; if I wish to explain to him who asks, I know not ...

Quote:But what now is manifest and clear is, that neither are there future nor past things. Nor is it fitly said, "There are three times, past, present and future;" but perchance it might be fitly said, "There are three times; a present of things past, a present of things present, and a present of things future." For these three do somehow exist in the soul, and otherwise I see them not: present of things past, memory; present of things present, sight; present of things future, expectation. If of these things we are permitted to speak, I see three times, and I grant there are three. It may also be said, "There are three times, past, present and future," as usage falsely has it. See, I trouble not, nor gainsay, nor reprove; provided always that which is said may be understood, that neither the future, nor that which is past, now is. For there are but few things which we speak properly, many things improperly; but what we may wish to say is understood.

Quote:But how is that future diminished or consumed which as yet is not? Or how does the past, which is no longer, increase, unless in the mind which enacts this there are three things done? For it both expects, and considers, and remembers, that that which it expects, through that which it considers, may pass into that which it remembers. Who, therefore, denies that future things as yet are not? But yet there is already in the mind the expectation of things future. And who denies that past things are now no longer? But, however, there is still in the mind the memory of things past. And who denies that time present wants space, because it passes away in a moment? But yet our consideration endures, through which that which may be present may proceed to become absent. Future time, which is not, is not therefore long; but a "long future" is "a long expectation of the future." Nor is time past, which is now no longer, long; but a long past is "a long memory of the past."
