the self-subsistent is set apart from things measured by time in respect to its substance. For if the self-subsistent is ungenerated, it would not be measured by time in respect to its being; for generation is concerned with the nature that is measured by time. Therefore none of the self-subsistent things subsists in time. 52 Everything eternal is whole at once; whether it has only its substance as eternal, having it present all at once, and not part of it having already subsisted, and part about to subsist hereafter, which does not yet exist, but however much it is able to be, so much it possesses already as a whole without diminution and without increase; or whether its activity in addition to its substance, having this also all together and standing in the same measure of perfection and as it were fixed according to one and the same limit immovably and unchangeably. For if the eternal is (as its name also indicates) that which always is, and "to be at some time" and "to become" are different from "always being", there must not be a "before" and an "after"; for it will be generation, and not being. But where there is neither "before" and "after" nor "was" and "will be", but only the "to be" which is, each thing that is, is whole at once. And the same applies also to its activity. From this it is clear that eternity is the cause for things to be wholes, if indeed everything eternal, whether in respect to substance or to activity, has its whole substance or activity present to it at once. 53 Before all eternal things eternity pre-exists, and before all things in time time pre-subsists. For if everywhere the participated exist before the participants and the unparticipated before the participated, it is clear that the eternal thing is one thing, the eternity in the eternal thing is another, and eternity in itself is another; the first as participant, the second as participated, and the third as unparticipated; and the temporal thing is another (for it is a participant), and the time in it is another (for it is participated), and the time before this, being unparticipated. And of these, each of the unparticipated is everywhere and in all things the same; but the participated is only in those things by which it is participated. For many are both the eternal things and the temporal things, in all of which there is eternity by participation and divided time; but the indivisible eternity and the one time are prior to these, the one being the eternity of eternities, and the other the time of times, being the principles of subsistence for the participated things. 54 All eternity is the measure of eternal things, and all time of things in time; and these two are the only measures among beings of life and of motion. For everything that measures either measures part by part or is applied all at once as a whole to the thing measured. Therefore, that which measures as a whole is eternity, and that which measures part by part is time; therefore there are only two measures, the one of eternal things, the other of things that are in time. 55 Everything that subsists in time either exists for all time or has its subsistence at some time in a part of time. For if all processions are through likeness, and prior to things that are in every way unlike there subsist things continuous with the first principles that are more like them than unlike, and it is impossible for things that come to be in a part of time to be joined to eternal things (for they are distinct both as things that come to be from things that are, and as things that exist 'at some time' from things that subsist 'always'), and intermediate between these and those are the things that are in some way like those, and in some way unlike, therefore, the intermediate between things that come to be 'at some time' and things that 'always are' is either that which 'always comes to be' or that which 'is at some time'—and this is either 'that which at some time is not truly' or 'that which at some time truly is'. But it is impossible for 'that which at some time truly is' to exist, and 'that which at some time is not truly' is the same as that which 'comes to be'; therefore, 'that which is at some time' is not an intermediate. It remains, therefore, that 'that which always comes to be' is the intermediate between both, by its 'coming to be' joined to the inferior things, and by its 'always' imitating the eternal nature. From these things, then, it is clear that perpetuity is twofold, one being eternal, and the other in time; the one a static perpetuity, the other a perpetuity that comes to be; and the one having its being gathered and all at once, the other poured out and unfolded according to temporal extension; and the one is a whole in itself, the other consists of parts, each of which is separate according to before and after. 56 Everything produced by secondary beings is also produced in a greater degree from the prior and more causal beings, from which the secondary beings themselves were produced. For if the secondary being has its whole substance from that which is prior to it, its power of producing also comes from there; for the productive powers are in the producers according to substance, and they complete their substance.
