THE FIRST THINKING PRINCIPLE IS THE SECOND PRINCIPLE.
Project Gutenberg EPUB3 edition
Plotinus and Guthrie, Kenneth Sylvan
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.
