EMPEDOCLES TAUGHT THE SAME THING.
In the system of Empedocles, discord divides, and concord unites; now this second principle is posited as incorporeal, and the elements play the part of matter.[251]
ARISTOTLE TAUGHT THE SAME THING.
Aristotle, who lived at a later period, says that the First Principle is separated from (sense-objects), and that it is intelligible.[252] But when Aristotle says that He thinks himself, Aristotle degrades Him from the first rank. Aristotle also asserts the existence of other intelligible entities in a number equal to the celestial spheres, so that each one of them might have a principle of motion. About the intelligible entities, therefore, Aristotle advances a teaching different from that of Plato, and as he has no plausible reason for this change, he alleges necessity. A well-grounded objection might here be taken against him. It seems more reasonable to suppose that all the spheres co-ordinated in a single system should, all of them, stand in relation to the One and the First. About Aristotle's views this question also might be raised: do the intelligible entities depend on the One and First, or are there several principles for the intelligible entities? If the intelligible entities depend on the One, they will no doubt be arranged symmetrically, as, in the sense-sphere, are the spheres, each of which contains another, and of which a single One, exterior to the others, contains them, and dominates them all. Thus, in this case, the first intelligible entity will contain all entities up there, and will be the intelligible world. Just as the spheres are not empty, as the first is full of stars, and as each of the others also is full of them, so above their motors will contain many entities, and everything will have a more real existence. On the other hand, if each of the intelligible entities is a principle, all will be contingent. How then will they unite their action, and will they, by agreement, contribute in producing a single effect, which is the harmony of heaven? Why should sense-objects, in heaven, equal in number their intelligible motors? Again, why are there several of these, since they are incorporeal, and since no matter separates them from each other?
WHAT THE PYTHAGOREANS TAUGHT ON THE SUBJECT.
Among ancient philosophers, those who most faithfully followed the doctrine of Pythagoras, of his disciples, and of Pherecydes, have specially dealt with the intelligible.[253] Some of them have committed their opinions to their written works; others have set them forth only in discussions that have not been preserved in writing. There are others of them, also, who have left us nothing on the subject.
TO THE THREE PRINCIPLES IN THE UNIVERSE MUST CORRESPOND THREE PRINCIPLES IN US.
10. Above existence, therefore, is the One. This has by us been proved as far as could reasonably be expected, and as far as such subjects admit of demonstration. In the second rank are Existence and Intelligence; in the third, the Soul. But if these three principles, the One, Intelligence, and the Soul, as we have said, obtain in nature, three principles must also obtain within us. I do not mean that these three principles are in sense-objects, for they are separate therefrom; they are outside of the sense-world, as the three divine principles are outside of the celestial sphere, and, according to Plato's expression,[254] they constitute the "the interior man." Our soul, therefore, is something divine; it has a nature different (from sense-nature), which conforms to that of the universal Soul. Now the perfect Soul possesses intelligence; but we must distinguish between the intelligence that reasons (the discursive reason), and the Intelligence that furnishes the principles of reasoning (pure intelligence). The discursive reason of the soul has no need, for operation, of any bodily organ;[255] in its operations, it preserves all its purity, so that it is capable of reasoning purely. When separated from the body, it must, without any hesitation, be ranked with highest intellectual entities. There is no need of locating it in space; for, if it exist within itself, outside of body, in an immaterial condition, it is evidently not mingled with the body, and has none of its nature. Consequently Plato[256] says, "The divinity has spread the Soul around the world." What he here means is that a part of the Soul remains in the intelligible world. Speaking of our soul he also says, "she hides her head in heaven."[257] He also advises us to wean the soul from the body; and he does not refer to any local separation, which nature alone could establish. He means that the soul must not incline towards the body, must not abandon herself to the phantoms of imagination, and must not, thus, become alienated from reason. He means that the soul should try to elevate to the intelligible world her lower part which is established in the sense-world, and which is occupied in fashioning the body.[258]
