Chapter 12.—From the Definitions Given of Sin and Will, He Overthrows the Entire Heresy of the Manichæans. Likewise from the Just Condemnation of Evil Souls It Follows that They are Evil Not by Nature But by Will. That Souls are Good By Nature, to Which the Pardon of Sins is Granted.
16. Come now, let us see in what respect these things would have aided us. Much every way, so that I should have desired nothing more; for they end the whole cause; for whoever consulting in the inner mind, where they are more pronounced and assured, the secrets of his own conscience, and the divine laws absolutely imposed upon nature, grants that these two definitions of will and sin are true, condemns without any hesitation by the fewest and the briefest, but plainly the most invincible reasons, the whole heresy of the Manichæans. Which can be thus considered. They say that there are two kinds of souls, the one good, which is in such a way from God, that it is said not to have been made by Him out of any material or out of nothing, but to have proceeded as a certain part from the very substance itself of God; the other evil, which they believe and strive to get others to believe pertains to God in no way whatever; and so they maintain that the one is the perfection of good, but the other the perfection of evil, and that these two classes were at one time distinct but are now commingled. The character and the cause of this commingling I had not yet heard; but nevertheless I could have inquired whether that evil kind of souls, before it was mingled with the good, had any will. For if not, it was without sin and innocent, and so by no means evil. But if evil in such a way, that though without will, as fire, yet if it should touch the good it would violate and corrupt it; how impious it is to believe that the nature of evil is powerful enough to change any part of God, and that the Highest Good is corruptible and violable! But if the will was present, assuredly there was present, no one compelling, a movement of the mind either towards not losing something or obtaining something. But this something was either good, or was thought to be good, for not otherwise could it be earnestly desired. But in supreme evil, before the commingling which they maintain, there never was any good. Whence then could there be in it either the knowledge or the thought of good? Did they wish for nothing that was in themselves, and earnestly desire that true good which was without? That will must truly be declared worthy of distinguished and great praise by which is earnestly desired the supreme and true good. Whence then in supreme evil was this movement of mind most worthy of so great praise? Did they seek it for the sake of injuring it? In the first place, the argument comes to the same thing. For he who wishes to injure, wishes to deprive another of some good for the sake of some good of his own. There was therefore in them either a knowledge of good or an opinion of good, which ought by no means to belong to supreme evil. In the second place, whence had they known, that good placed outside of themselves, which they designed to injure, existed at all. If they had intellectually perceived it, what is more excellent than such a mind? Is there anything else for which the whole energy of good men is put forth except the knowledge of that supreme and sincere good? What therefore is now scarcely conceded to a few good and just men, was mere evil, no good assisting, then able to accomplish? But if those souls bore bodies and saw the supreme good with their eyes, what tongues, what hearts, what intellects suffice for lauding and proclaiming those eyes, with which the minds of just men can scarcely be compared? How great good things we find in supreme evil! For if to see God is evil, God is not a good; but God is a good; therefore to see God is good; and I know not what can be compared to this good. Since to see anything is good, whence can it be made out that to be able to see is evil? Therefore whatever in those eyes or in those minds brought it about, that the divine essence could be seen by them, brought about a great thing and a good thing most worthy of ineffable praise. But if it was not brought about, but it was such in itself and eternal, it is difficult to find anything better than this evil.
