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.
