Enneads VI.4: The One Identical Essence is Everywhere Entirely Present
Sixth Ennead, Book Four
Why the World-soul Is Everywhere Entire in the World-body
1. Is it because the body of the universe is so great that the Soul is everywhere present in the universe, though being naturally divisible in (human) bodies? Or it is by herself, that she is everywhere present? In the latter case, she has not been drawn away everywhere by the body, but the body found her everywhere in existence before it; thus, in whatever place it may be, it found the Soul present before it itself was part of the universe, and the total body of the universe was located in the Soul that existed already.
HOW COULD THE SOUL HAVE NO MAGNITUDE, IF SHE ALREADY FILLED ALL SPACE?
But if the Soul had such an extension before the body approached her, if she already filled all space, how can she have no magnitude? Besides, how could she have been present in the universe when the latter did not yet exist? Last, being considered indivisible and non-extended, is she everywhere present without having any magnitude? If the answer be that she extended herself throughout the body of the universe without herself being corporeal, the question is not yet resolved by thus accidentally attributing magnitude to the Soul; for it would then be reasonable to ask how she grew great by accident. The Soul could not extend herself in the entire body in the same manner as quality, as for instance, sweetness or color; for these are passive modifications of the bodies, so that one must not be astonished to see a modification spread all over the modified body, being nothing by itself, inhering in the body, and existing only within it; that is why the soul necessarily has the same magnitude as the body. Besides, the whiteness of one part of the body does not share the experience[1] (or, "passion") experienced by the whiteness of another part; the whiteness of one part is identical, in respect to species, to the whiteness of another part; but it is not identical therewith in respect to number; on the contrary, the part of the soul which is present in the foot is identical with the portion of the soul present in the hand, as may be seen in the percepts thereof. Last, what is identical in the qualities is divisible, while that which is identical in the soul is indivisible; if it be said to divide, it is in this sense that it is present everywhere.
THE SOUL WAS CAPABLE OF EXTENSION BEFORE THE EXISTENCE OF THE BODY.
In view of these facts, let us, starting from the very beginning, explain in a clear and plausible manner, how the soul, being incorporeal and extended, could, nevertheless, have assumed such an extension, either before the bodies, or in the bodies. If indeed one see that she was capable of assuming extension before the bodies existed, it will be easily understood that she could have done so within the bodies.
