Enneads VI.4: The One Identical Essence is Everywhere Entirely Present
Participation Can Be Only in the Intelligible
When a being participates in something, evidently it does not participate in itself; for thus it would really participate in nothing, and would remain what it was. The body that participates in something must, therefore, not participate in corporeal nature, for it possesses it already. Consequently, the body will not participate in the corporeal nature, any more than a magnitude would participate in a magnitude, which it possesses already. Let us even admit that a magnitude be increased, yet on that account alone it would not participate in magnitude; for a two-foot object does not become a three-foot object, but the object which first had a certain quantity merely changes to some other quantity; otherwise two would become three. Thus, since that which has extension and is divided participates in genus that is different, and even very different, the thing in which it participates must neither be divided, nor have extension; but have absolutely no kind of quantity. Consequently, the (being) which everywhere is present entire must be present, though remaining indivisible. It is not indivisible merely because it is small, which would not make it any less divisible; only, it would no more be proportioned to the universe, it would not spread in the corporeal mass in the degree that it increases. Neither does it resemble a point, but it includes an infinity of points; consequently what you might suppose was a point would include an infinity of (separate) points, and could not be continuous, nor, consequently, proportion itself to the universe. If then every corporeal mass possess the (being) which is present everywhere, it must possess it entire in all the parts that compose it.
NOTHING IN THE UNIVERSAL SOUL IS BEGOTTEN; IT ONLY SEEMS SO.
14. But if one and the single Soul be in each person, how does each have his own soul? How then can one soul be good, while the other is evil? The universal Soul communicates her life to each, for she contains all the souls and all the intelligences. She possesses simultaneously unity and infinity; in her breast she contains all the souls, each distinct from her, but not separated; otherwise how could the Soul possess the infinite? It might still be objected that the universal Soul simultaneously contains all things, all lives, all souls, all the intelligences; that these are not each circumscribed by limits, and that that is the reason they form a unity. Indeed, there had to be in the universal Soul a life not only one, but infinite, and yet single; this one life had to be one so far as it was all lives, as these did not get confused in this unity, but that they should originate there, while at the same time they should remain located in the place from where they had started; or rather, they never left the womb of the universal Soul, for they have always subsisted in the same state. Indeed, nothing was begotten in the universal Soul; she did not really divide herself, she only seems divided in respect to what receives her; everything within her remains what it has always been. But that which was begotten (namely, the body) approaches the Soul, and seems to unite with her, and depends on her.
