How the Soul Mediates Between Indivisible and Divisible Essence.
OUTLINE OF THE PSYCHOLOGICAL STUDY OF IV. 7.
1. While studying the nature ("being") of the soul, we have shown (against the Stoics) that she is not a body; that, among incorporeal entities, she is not a "harmony" (against the Pythagoreans); we have also shown that she is not an "entelechy" (against Aristotle), because this term, as its very etymology implies, does not express a true idea, and reveals nothing about the soul's (nature itself); last, we said that the soul has an intelligible nature, and is of divine condition; the "being" or nature of the soul we have also, it would seem, clearly enough set forth. Still, we have to go further. We have formerly established a distinction between intelligible and sense nature, assigning the soul to the intelligible world. Granting this, that the soul forms part of the intelligible world, we must, in another manner, study what is suitable to her nature.
EXISTENCE OF DIVISIBLE BEINGS.
To begin with, there are (beings) which are quite divisible and naturally separable. No one part of any one of them is identical with any other part, nor with the whole, of which each part necessarily is smaller than the whole. Such are sense-magnitudes, or physical masses, of which each occupies a place apart, without being able to be in several places simultaneously.
DESCRIPTION OF INDIVISIBLE ESSENCE.
On the other hand, there exists another kind of essence ("being"), whose nature differs from the preceding (entirely divisible beings), which admits of no division, and is neither divided nor divisible. This has no extension, not even in thought. It does not need to be in any place, and is not either partially or wholly contained in any other being. If we dare say so, it hovers simultaneously over all beings, not that it needs to be built up on them,[353] but because it is indispensable to the existence of all. It is ever identical with itself, and is the common support of all that is below it. It is as in the circle, where the centre, remaining immovable in itself, nevertheless is the origin of all the radii originating there, and drawing their existence thence. The radii by thus participating in the existence of the centre, the radii's principle, depend on what is indivisible, remaining attached thereto, though separating in every direction.[354]
BETWEEN THEM IS AN INDIVISIBLE ESSENCE WHICH BECOMES DIVISIBLE WITHIN BODIES.
Now between entirely indivisible ("Being") which occupies the first rank amidst intelligible beings, and the (essence) which is entirely divisible in its sense-objects, there is, above the sense-world, near it, and within it, a "being" of another nature, which is not, like bodies, completely divisible, but which, nevertheless, becomes divisible within bodies. Consequently, when you separate bodies, the form within them also divides, but in such a way that it remains entire in each part. This identical (essence), thus becoming manifold, has parts that are completely separated from each other; for it then is a divisible form, such as colors, and all the qualities, like any form which can simultaneously remain entire in several things entirely separate, at a distance, and foreign to each other because of the different ways in which they are affected. We must therefore admit that this form (that resides in bodies) is also divisible.
