Therefore, the First principle (the One) does not think; the second
(Intelligence) is the first thinking principle; the third (the Soul) is
the second thinking principle. If the first Principle thought, it would
possess an attribute; consequently, instead of occupying the first
rank, it would occupy only the second; instead of being One, it would
be manifold, and would be all the things that it thought; for it would
already be manifold, even if it limited itself to thinking itself.
