THE ONLY SUPREME PRINCIPLES MUST THEN BE UNITY, INTELLIGENCE AND SOUL.
Consequently there are no principles other (than the three divine hypostatic substances); and the first rank will have to be assigned to Unity, the second to Intelligence, as the first thinking principle,[277] and the third to the Soul. Such indeed is the natural order, which admits of no further principles, in the intelligible world. If less be claimed, it is because of a confusion between the Soul and Intelligence, or Intelligence with the First; but we have often pointed out their mutual differences.[278] The only thing left is to examine if there might not be more than these three hypostatic substances; and in this case, what their nature might be.
