Enneads IV.4: Questions About the Soul
In the Intelligible Anteriority Refers to Order, Not to Time
It may be objected that it may happen that the soul will divide and develop something which was unitary. This thing must then already have been divided in intelligence, but such a division is more like an impression. As anteriority or posteriority in ideas does not refer to time, so also will the mental conception of anteriority and posteriority not be subject to temporal conditions, but refer to order (which presides over intelligible things). For instance, on considering a tree's order that extends from the roots to the tree-top, priority and posteriority exists only under the relation of order, inasmuch as the whole plant is perceived at one single glance.
INTELLIGENCE IS NOT A UNITY; BUT ITS MANIFOLD IS PRODUCED BY A UNITY.
How can things be prior or posterior, if the soul that contemplates the One embrace all things? The potentiality which is One is one in such a manner that it is multiple when it is contemplated by another principle (Intelligence), because then it is not simultaneously all things in one single thought. Indeed, the actualizations (of Intelligence) are not a unity; but they are all produced by an ever permanent potentiality; they therefore become multiple in the other principles (the intelligibles); for Intelligence, not being unity itself, can receive within its breast the nature of the multiple which did not formerly exist (in the One).
