At no time, therefore, hadst Thou not made anything, because Thou hadst made time itself. And no times are co-eternal with Thee, because Thou remainest for ever; but should these continue, they would not be times. 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.
i would like to to write more on the concept of time as it relates to physics and thermodynamics. but i don't know where to begin writing.
for now, a reflection on the subject to mull...with a little catholic metaphysics on what-begets-god for ya to also chomp on.
