They will object that parts must necessarily fall under one ideal-form with their wholes. And they will adduce Plato as expressing their view where, in demonstrating that the All is ensouled, he says “As our body is a portion of the BODY OF THE ALL, so our soul is a portion of the soul of the All.” It is admitted on clear evidence that we are borne along by the Circuit of the All; we will be told that – taking character and destiny from it, strictly inbound with it – we must derive our souls, also, from what thus bears us up, and that as within ourselves every part absorbs from our soul so, analogically, we, standing as parts to the universe, absorb from the Soul of the All as parts of it. They will urge also that the dictum “The collective soul cares for all the unensouled,” carries the same implication and could be uttered only in the belief that nothing whatever of later origin stands outside the soul of the universe, the only soul there can be there to concern itself with the unensouled. Enneads IV,3,
So far, so good: but what of the passage in the Philebus taken to imply that the other souls are parts of the All-Soul? The statement there made does not bear the meaning read into it; it expresses only, what the author was then concerned with, that the heavens are ensouled – a teaching which he maintains in the observation that it is preposterous to make the heavens soulless when we, who contain a part of the BODY OF THE ALL, have a soul; how, he asks, could there be soul in the part and none in the total. Enneads IV,3,
This means that it is no external limit that defines the individual being or the extension of souls any more than of God; on the contrary each in right of its own power is all that it chooses to be: and we are not to think of it as going forth from itself (losing its unity by any partition): the fact is simply that the element within it, which is apt to entrance into body, has the power of immediate projection any whither: the soul is certainly not wrenched asunder by its presence at once in foot and in finger. Its presence in the All is similarly unbroken; over its entire range it exists in every several part of everything having even vegetal life, even in a part cut off from the main; in any possible segment it is as it is at its source. For the BODY OF THE ALL is a unit, and soul is everywhere present to it as to one thing. Enneads IV,3,
The kosmos is like a net which takes all its life, as far as ever it stretches, from being wet in the water, and has no act of its own; the sea rolls away and the net with it, precisely to the full of its scope, for no mesh of it can strain beyond its set place: the soul is of so far-reaching a nature – a thing unbounded – as to embrace the entire BODY OF THE ALL in the one extension; so far as the universe extends, there soul is; and if the universe had no existence, the extent of soul would be the same; it is eternally what it is. The universe spreads as broad as the presence of soul; the bound of its expansion is the point at which, in its downward egression from the Supreme, it still has soul to bind it in one: it is a shadow as broad as the Reason-Principle proceeding from soul; and that Reason-Principle is of scope to generate a kosmic bulk as vast as lay in the purposes of the Idea (the Divine forming power) which it conveys. Enneads IV,3,
For ourselves, while whatever in us belongs to the BODY OF THE ALL should be yielded to its action, we ought to make sure that we submit only within limits, realizing that the entire man is not thus bound to it: intelligent servitors yield a part of themselves to their masters but in part retain their personality, and are thus less absolutely at beck and call, as not being slaves, not utterly chattels. Enneads IV,4,
