Now when we consider the nature of some being, it should be studied in its rarest condition, since extraneous additions hinder it from being rightly judged. The soul must be therefore considered only after abstraction of foreign things, or rather, he who makes this abstraction should observe himself in that condition. He then will not doubt that he is immortal, when he sees himself in the pure world of intelligence. He will see his intelligence occupied, not in the observation of some sense-object that is mortal, but in thinking the eternal by an equally eternal faculty.[83] He will see all the entities in the intelligible world, and he will see himself become intelligible, radiant, and illuminated by the truth emanating from the Good, which sheds the light of truth on all intelligible entities.[84] Then (like Empedocles, in Diog. Laertes[85]), he will have the right to say:
"Farewell, I am now an immortal divinity."
For he has ascended to the divinity, and has become assimilated thereto. As purification permits one to know the better things, so the notions we have within us, and which constitute real science, are made clear. Indeed, it is not by an excursion among external objects that the soul attains the intuition of wisdom and virtue, but by re-entering into herself, in thinking herself in her primitive condition. Then she clears up and recognizes in herself the divine statues, soiled by the rust of time. Likewise, if a piece of gold were animated and released itself from the earth by which it was covered, after first having been ignorant of its real nature because it did not see its own splendor, it would admire itself when considering itself in its purity; it would find that it had no need of a borrowed beauty, and would consider itself happy to remain isolated from everything else.[86]
EVEN ON THE STOIC HYPOTHESIS THE SOUL MUST BE IMMORTAL.
11. (16). What sensible man, after having thus considered the nature of the soul, could still doubt of the immortality of a principle which derives life from naught but itself, and which cannot lose it? How could the soul lose life, since she did not borrow it from elsewhere, and since she does not possess it as fire possesses heat? For, without being an accident of fire, the heat, nevertheless, is an accident of its matter; for fire can perish. But, in the soul, life is not an accident that comes to add itself to a material subject to constitute a soul. In fact, there is here an alternative: either life is a genuine "being," which is alive by itself; in which case this "being" is the soul that we are seeking to discover, and immortality cannot be refused her; or the soul is a composite, and she must be decomposed until we arrive at something immortal which moves by itself; and such a principle could not be subject to death. Further, when (Stoics) say that life is only an accidental modification of matter, they are thereby forced to acknowledge that the principle that imparted this modification to matter is immortal, and incapable of admitting anything contrary to what it communicates (that is, life, as said Plato, in his Phaedo[87]), but there is only a single nature that possesses life in actualization.
THERE IS NO CONCEIVABLE WAY IN WHICH SOUL COULD PERISH.
12. (17). (The Stoics), indeed, claim that every soul is perishable. In this case, everything should long since have been destroyed. Others might say that our soul were mortal, while the universal Soul were immortal. On them, however, is the burden of proof of a difference between the individual and universal souls. Both of them, indeed, are a principle of movement; both live by themselves; both grasp the same object by the same faculty, either by thinking the things contained in heaven, or by considering the nature ("being") of each being, ascending unto the first principle. Since our soul thinks absolute essences either by the notions she finds within herself, or by reminiscence, she evidently is prior to the body. Possessing knowledge of eternal entities, she herself must be eternal. All that dissolves, existing only by its compositeness, can naturally dissolve in the same manner that it became composite. But the soul is a single, simple actualization, whose essence is life; not in this manner therefore can the soul perish. Neither could the soul perish by division into a number of parts; for, as we have shown, the soul is neither a mass nor a quantity. As little could the soul perish by alteration; for when alteration destroys anything, it may remove its form, but leaves its matter; alteration, therefore, is a characteristic of something composite. Consequently as the soul cannot perish in any of these ways, she is imperishable.
DESCENT INTO THE BODY NEED NOT CONFLICT WITH THE ETERNITY OF SOUL.
13. (18). If intelligible entities are separated from sense objects, how does it happen that the soul descends into a body?[88] So long as the soul is a pure and impassible intelligence, so long as she enjoys a purely intellectual life like the other intelligible beings, she dwells among them; for she has neither appetite nor desire. But that part which is inferior to intelligence and which is capable of desires, follows their impulsion, "proceeds" and withdraws from the intelligible world. Wishing to ornament matter on the model of the Ideas she contemplated in Intelligence, in haste to exhibit her fruitfulness, and to manifest the germs she bears within her (as said Plato, in the Banquet[89]), the soul applies herself to produce and create, and, as result of this application, she is, as it were, orientated (or, in "tension") towards sense-objects. With the universal Soul, the human soul shares the administration of the whole world, without, however, entering it; then, desiring to administer some portion of the world on her own responsibility, she separates from the universal Soul, and passes into a body. But even when she is present with the body, the soul does not devote herself entirely to it, as some part of her always remains outside of it; that is how her intelligence remains impassible.[90]
