The whole question turns on the distinction between being in Time and being in Eternity, and this will be best realized by probing to the Nature of Time.We must, therefore, descend from Eternity to the investigation of Time, to the realm of Time: till now we have been taking the upward way; we must now take the downward-not to the lowest levels but within the degree in which Time itself is a descent from Eternity.
If the venerable sages of former days had not treated of Time, our method would be to begin by linking to [the idea of] Eternity [the idea of] its Next [its inevitable downward or outgoing subsequent in the same order], then setting forth the probable nature of such a Next and proceeding to show how the conception thus formed tallies with our own doctrine.
But, as things are, our best beginning is to range over the most noteworthy of the ancient opinions and see whether any of them accord with ours.
Existing explanations of Time seem to fall into three classes:
Time is variously identified with what we know as Movement, with a moved object, and with some phenomenon of Movement: obviously it cannot be Rest or a resting object or any phenomenon of rest, since, in its characteristic idea, it is concerned with change.
Of those that explain it as Movement, some identify it with Absolute Movement [or with the total of Movement], others with that of the All.Those that make it a moved object would identify it with the orb of the All.Those that conceive it as some phenomenon, or some period, of Movement treat it, severally, either as a standard of measure or as something inevitably accompanying Movement, abstract or definite.
8.Movement Time cannot be- whether a definite act of moving is meant or a united total made up of all such acts- since movement, in either sense, takes place in Time.And, of course, if there is any movement not in Time, the identification with Time becomes all the less tenable.
In a word, Movement must be distinct from the medium in which it takes place.
And, with all that has been said or is still said, one consideration is decisive: Movement can come to rest, can be intermittent; Time is continuous.
We will be told that the Movement of the All is continuous [and so may be identical with Time].
But, if the reference is to the Circuit of the heavenly system [it is not strictly continuous, or equable, since] the time taken in the return path is not that of the outgoing movement; the one is twice as long as the other: this Movement of the All proceeds, therefore, by two different degrees; the rate of the entire journey is not that of the first half.
Further, the fact that we hear of the Movement of the outermost sphere being the swiftest confirms our theory.Obviously, it is the swiftest of movements by taking the lesser time to traverse the greater space the very greatest- all other moving things are slower by taking a longer time to traverse a mere segment of the same extension:
in other words, Time is not this movement.
And, if Time is not even the movement of the Kosmic Sphere much less is it the sphere itself though that has been identified with Time on the ground of its being in motion.
Is it, then, some phenomenon or connection of Movement?
Let us, tentatively, suppose it to be extent, or duration, of Movement.
Now, to begin with, Movement, even continuous, has no unchanging extent [as Time the equable has], since, even in space, it may be faster or slower; there must, therefore, be some unit of standard outside it, by which these differences are measurable, and this outside standard would more properly be called Time.And failing such a measure, which extent would be Time, that of the fast or of the slow- or rather which of them all, since these speed-differences are limitless?
Is it the extent of the subordinate Movement [= movement of things of earth]?
Again, this gives us no unit since the movement is infinitely variable; we would have, thus, not Time but Times.
The extent of the Movement of the All, then?
The Celestial Circuit may, no doubt, be thought of in terms of quantity.It answers to measure- in two ways.First there is space;the movement is commensurate with the area it passes through, and this area is its extent.But this gives us, still, space only, not Time.
Secondly, the circuit, considered apart from distance traversed, has the extent of its continuity, of its tendency not to stop but to proceed indefinitely: but this is merely amplitude of Movement; search it, tell its vastness, and, still, Time has no more appeared, no more enters into the matter, than when one certifies a high pitch of heat; all we have discovered is Motion in ceaseless succession, like water flowing ceaselessly, motion and extent of motion.
