But why could time not exist before the existence of a soul to measure it? (Aristotle) might have answered that it was begotten by the soul. The mere fact that the soul measures time need not necessarily imply that the soul produced the time; time, along with its suitable quantity, would exist even if nobody measured it. If however it be said that it is the soul that makes use of extension to measure time, we will answer that this is of no importance to determine the notion of time. POLEMIC AGAINST EPICURUS: TIME IS NOT AN ACCIDENT OR CONSEQUENCE OF MOVEMENT. 9. (10). When (Epicurus[457]) says that time is a consequence of movement, he is not explaining the nature of time; this would demand a preliminary definition of the consequence of movement. Besides, this alleged consequence of movement--granting the possibility of such a consequence--must be prior, simultaneous, or posterior. For, in whatever way we conceive of it, it is within time. Consequently, if the consequence of movement be time, the result would be that time is a consequence of movement in time (which is nonsense). PLOTINOS CAN GO NO FURTHER IN REFUTING ENDLESS DEFINITIONS OF TIME. Now, as our purpose is to discover, not what time is not, but what it really is, we notice that this question has been treated at great length by many thinkers before us; and if we were to undertake to consider all existing opinions on the subject, we would be obliged to write a veritable history of the subject. We have here, however, gone to the limit of our ability in treating it without specializing in it. As has been seen, it is easy enough to refute the opinion that time is the measure of the movement of the universe, and to raise against this opinion the objections that we have raised against the definition of time as the measure of movement in general, opposing thereto the irregularity of movement, and the other points from which suitable arguments may be drawn. We are therefore free to devote ourselves to an explanation of what time really is. THE NATURE OF TIME WILL BE REVEALED BY ITS ORIGIN.
