Enneads II.9: Against the Gnostics; or, That the Creator and the World are Not
A Differentiated Reason Would Deprive the Soul of Consciousness
Last, if we suppose that Reason is derived from Intelligence, and then from reason in the soul derive another reason which would be derived from Reason in itself, so as to constitute a principle intermediary between Intelligence and Soul, the Soul would be deprived of the power of thought. For thus the Soul, instead of receiving reason from Intelligence, would receive reason from an intermediary principle. Instead of possessing Reason itself, the Soul would possess only an adumbration of Reason; the Soul would not know Intelligence, and would not be able to think.
NO MORE THAN THREE PRINCIPLES ADMITTED BECAUSE OF THE UNITY OF CONSCIOUSNESS.
2. In the intelligible world, therefore, we shall not recognize more than three principles (Unity, Intelligence, and Soul), without those superfluous and incongruous fictions. We shall insist that there is a single Intelligence that is identical, and immutable, which imitates its Father so far as it can. Then there is our soul, of which one part ever remains among the intelligibles, while one part descends to sense-objects, and another abides in an intermediary region. As our soul is one nature in several powers, she may at times entirely rise to the intelligible world, with the best part of herself and of essence; at other times the soul’s lower part allows itself to be dragged down to the earth, carrying with it the intermediate portion; for the soul cannot be entirely dragged down. This being dragged down occurs only because the soul does not abide in the better region. While dwelling in it, the Soul, which is not a part (of it) and of which we are not a part, has given to the body of the universe all the perfections of which she was capable. The Soul governs it by remaining quiet, without reasoning, without having to correct anything. With wonderful power she beautifies the universe by the contemplation of the intelligible world. The more the Soul attaches herself to contemplation, the more powerful and beautiful she is; what she receives from above, she communicates to the sense-world, and illuminates because she herself is always illuminated (by Intelligence).
