The soul's faculty of growth remains to be considered. This at least might be thought an inseparable entelechy. But neither does that suit her nature. For if the principle of every plant is in its root, and if growth takes place around and beneath it,[79] as occurs in many plants, it is evident that the soul's faculty of growth, abandoning all the other parts, has concentrated in the root alone; it, therefore, was not distributed all around the soul, like an inseparable entelechy. Add that this soul, before the plant grows, is already contained in the small body (of the seed). If then, after having vivified a great plant, the soul's faculty of growth can condense into a small space, and if later it can, from this small space, again spread over a whole plant, it is evidently entirely separable from the (plant's) matter.
THE ENTELECHY IS NOT A FORM OF THE BODY, AS THE SOUL TRANSMIGRATES.
Besides, as the soul is indivisible, the entelechy of the divisible body could not become divisible as is the body. Besides, the same soul passes from the body of one animal into the body of some other. How could the soul of the first become that of the second, if she were only the entelechy of a single one? The example of animals that metamorphose demonstrates the impossibility of this theory. The soul, therefore, is not the simple form of a body; she is a genuine "being," which does not owe its existence merely to her being founded on the body, but which, on the contrary, exists before having become the soul of some individual animal. It is, therefore, not the body that begets the soul.
THE SOUL IS AN INCORPOREAL AND IMMORTAL ESSENCE. THE SOUL BEING NONE OF CORPOREAL POSSIBILITIES, MUST BE INCORPOREAL.
c. What then can be the nature of the soul, if she is neither a body, nor a corporeal affection, while, nevertheless, all the active force, the productive power and the other faculties reside in her, or come from her? What sort of a "being," indeed, is this (soul) that has an existence independent of the body? She must evidently be a veritable "being." Indeed, everything corporeal must be classified as generated, and excluded from genuine "being," because it is born, and perishes, never really exists, and owes its salvation exclusively to participation in the genuine existence, and that only in the measure of its participation therein.
THE PERSISTENCE OF THE CHANGEABLE IMPLIES THE ETERNAL IN THE BACKGROUND.[80]
9. (14). It is absolutely necessary to postulate the existence of a nature different from bodies, by itself fully possessing genuine existence, which can neither be born nor perish. Otherwise, all other things would hopelessly disappear, as a result of the destruction of the existence which preserves both the individuals and the universe, as their beauty and salvation. The soul, indeed, is the principle of movement (as Plato thought, in the Phaedrus); it is the soul that imparts movement to everything else; the soul moves herself. She imparts life to the body she animates; but alone she possesses life, without ever being subject to losing it, because she possesses it by herself. All beings, indeed, live only by a borrowed life; otherwise, we would have to proceed from cause to cause unto infinity. There must, therefore, exist a nature that is primarily alive, necessarily incorruptible and immortal because it is the principle of life for everything else. It is thereon that must be founded all that is divine and blessed, that lives and exists by itself, that lives and exists supremely, which is immutable in its essence, and which can neither be born nor perish. How indeed could existence be born or perish? If the name of "existence" really suited it, it must exist forever, just as whiteness is not alternately black and white. If whiteness were existence itself, it would, with its "being" (or nature) (which is, to be whiteness), possess an eternal existence; but, in reality, it is no more than whiteness. Therefore, the principle that possesses existence in itself and in a supreme degree will always exist. Now this primary and eternal existence can not be anything dead like a stone, or a piece of wood. It must live, and live with a pure life, as long as it exists within itself. If something of it mingles with what is inferior, this part meets obstacles in its aspiration to the good; but it does not lose its nature, and resumes its former condition on returning to a suitable condition (as thought Plato, in his Phaedo[81]).
THE SOUL IS INCORPOREAL BECAUSE OF HER KINSHIP WITH THE DIVINE.
10. (15). The soul has affinities with the divine and eternal nature. This is evident, because, as we have demonstrated it, she is not a body, has neither figure nor color, and is impalpable. Consider the following demonstration. It is generally granted that everything that is divine and that possesses genuine existence enjoys a happy and wise life. Now let us consider the nature of our soul, in connection with that of the divine. Let us take a soul, not one inside of a body, which is undergoing the irrational motions of appetite and anger, and the other affections born of the body, but a soul that has eliminated all that, and which, so far as possible, had no intercourse with the body. Such a soul would show us that vices are something foreign to the nature of the soul, and come to her from elsewhere, and that, inasmuch as she is purified, she in her own right possesses the most eminent qualities, wisdom, and the other virtues (as thought Plato[82]). If the soul, when re-entering into herself, is such, how could she not participate in this nature that we have acknowledged to be suitable to every thing that is eternal and divine? As wisdom and real virtue are divine things, they could not dwell in a vile and mortal entity; the existence that receives them is necessarily divine, since it participates in divine things by their mutual affinity and community. Anyone who thus possesses wisdom and virtue in his soul differs little from the superior beings; he is inferior to them only by the fact of his having a body. If all men, or at least, if many of them held their soul in this disposition, no one would be sceptic enough to refuse to believe that the soul is immortal. But as we consider the soul in her present condition of being soiled by vices, no one imagines that her nature is divine and immortal.
