Chapter II.-What Sin is.
Some one will say: What assistance would this have furnished you against the Manichaeans? Wait a moment; permit me first also to define sin, which, every mind reads divinely written in itself, cannot exist apart from will. Sin therefore is the will to retain and follow after what justice forbids, and from which it is free to abstain. Although if it be not free, it is not will. But I have preferred to define more roughly than precisely. Should I not also have carefully examined those obscure books, whence I might have learned that no one is worthy of blame or punishment who either wills what justice does not prohibit him from willing, or does not do what he is not able to do? Do not shepherds on mountains, poets in theatres, unlearned in social intercourse, learned in libraries, masters in schools, priests in consecrated places, and the human race throughout the whole world, sing out these things? But if no one is worthy of blame and condemnation, who either does not act against the prohibition of justice, or who does not do what he cannot do, yet every sin is blameworthy and condemnable, who doubts then that it is sin, when willing is unjust, and not willing is free. And hence that definition is both true and easy to understand, and not only now but then also could have been spoken by me: Sin is the will of retaining or of obtaining, what justice forbids, and whence it is free to abstain?
Chapter 12.-From the Definitions Given of Sin and Will, He Overthrows the Entire Heresy of the Manichaeans. Likewise from the Just Condemnation of Evil Souls It Follows that They are Evil Not by Nature But by Will. That Souls are Good Bynature, 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 Manichaeans. 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.
17. Lastly, that these souls may have nothing of these praiseworthy things which by the reasonings of the Manichaeans they are compelled to have, I should have asked, whether God condemns any or no souls. If none, there is no judgment of rewards and punishments, no providence, and the world is administered by chance rather than by reason, or rather is not administered at all. For the name administration must not be given to chances. But if it is impious for all those that are bound by any religion to believe this, it remains either that there is condemnation of some souls, or that there are no sins. But if there are no sins, neither is there any evil. Which if the Manichaeans should say, they would slay their heresy with a single blow. Therefore they and I agree that some souls are condemned by divine law and judgment. But if these souls are good, what is that justice? If evil, are they so by nature, or by will? But by nature souls can in no way be evil. Whence do we teach this. From the above definitions of will and sin. For to speak of souls, and that they are evil, and that they do not sin, is full of madness; but to say that they sin without will, is great craziness, and to hold any one guilty of sin for not doing what he could not do, belongs to the height of iniquity and insanity. Wherefore whatever these souls do, if they do it by nature not by will, that is, if they are wanting in a movement of mind free both for doing and not doing, if finally no power of abstaining from their work is conceded to them; we cannot hold that the sin is theirs. But all confess both that evil souls are justly, and souls that have not sinned are unjustly condemned; therefore they confess that those souls are evil that sin. But these, as reason teaches, do not sin. Therefore the extraneous class of evil souls of the Manichaeans, whatever it may be, is a non-entity.
18. Let us now look at that good class of souls, which again they exalt to such a degree as to say that it is the very substance of God. But how much better it is that each one should recognize his own rank and merit, nor be so puffed up with sacrilegious pride as to believe that as often as he experiences a change in himself it is the substance of that supreme good, which devout reason holds and teaches to be unchangeable! For behold! since it is manifest that souls do not sin in not being such as they cannot be; it follows that these supposititious souls, whatever they may be, do not sin at all, and moreover that they are absolutely non-existent; it remains that since there are sins, they find none to whom to attribute them except the good class of souls and the substance of God. But especially are they pressed by Christian authority; for never have they denied that forgiveness of sins is granted when any one has been converted to God; never have they said (as they have said of many other passages) that some corrupter has interpolated this into the divine Scriptures. To whom then are sins attributed? If to those evil souls of the alien class, these also can become good, can possess the kingdom of God with Christ. Which denying, they [the Manichaeans] have no other class except those souls which they maintain are of the substance of God. It remains that they acknowledge that not only these latter also, but these alone sin. But I make no contention about their being alone in sinning; yet they sin. But are they compelled to sin by being commingled with evil? If so compelled that there was no power of resisting, they do not sin. If it is in their power to resist, and they voluntarily consent, we are compelled to find out through their [the Manichaean] teaching, why so great good things in supreme evil, why this evil in supreme good, unless it be that neither is that which they bring into suspicion evil, nor is that which they pervert by superstition supreme good?
Chapter 13.-From Deliberation on the Evil and on the Good Part It Results that Two Classes of Souls are Not to Be Held to. A Class of Souls Enticing to Shameful Deeds Having Been Conceded, It Does Not Follow that These are Evil by Nature, that the Others are Supreme Good.
19. But if I had taught, or at any rate had myself learned, that they rave and err regarding those two classes of souls, why should I have thenceforth thought them worthy of being heard or consulted about anything? That I might learn hence, that these two kinds of souls are pointed out, which in the course of deliberation assent puts now on the evil side, now on the good? Why is not this rather the sign of one soul which by free will can be borne here and there, swayed hither and thither? For it was my own experience to feel that I am one, considering evil and good and choosing one or the other, but for the most part the one pleases, the other is fitting, placed in the midst of which we fluctuate. Nor is it to be wondered at, for we are now so constituted that through the flesh we can be affected by sensual pleasure, and through the spirit by honorable considerations. Am I not therefore compelled to acknowledge two souls? Nay, we can better and with far less difficulty recognize two classes of good things, of which neither is alien from God as its author, one soul acted upon from diverse directions, the lower and the higher, or to speak more correctly, the external and the internal. These are the two classes which a little while ago we considered under the names sensible and intelligible, which we now prefer to call more familiarly carnal and spiritual. But it has been made difficult for us to abstain from carnal things, since our truest bread is spiritual. For with great labor we now eat this bread. For neither without punishment for the sin of transgression have we been changed from immortal into moral. So it happens, that when we strive after better things, habit formed by connection with the flesh and our sins in some way begin to militate against us and to put obstacles in our way, some foolish persons with most obtuse superstition suspect that there is another kind of souls which is not of God.
20. However even if it be conceded to them that we are enticed to shameful deeds by another inferior kind of souls, they do not thence make it evident that those enticing are evil by nature, or those enticed, supremely good. For it may be, the former of their own will, by striving after what was not lawful, that is, by sinning, from being good have become evil; and again they may be made good, but in such manner that for a long time they remain in sin, and by a certain occult suasion traduce to themselves other souls. Then, they may not be absolutely evil, but in their own kind, however inferior, they may exercise their own functions without any sin. But those superior souls to whom justice, the directress of things, has assigned a far more excellent activity, if they should wish to follow and to imitate those inferior ones, become evil, not because they imitate evil souls, but because they imitate in an evil way. By the evil souls is done what is proper to them, by the good what is alien to them is striven after. Hence the former remain in their own grade, the latter are plunged into a lower. It is as when men copy after beasts. For the four-footed horse walks beautifully, but if a man on all fours should imitate him, who would think him worthy even of chaff for food? Rightly therefore we generally disapprove of one who imitates, while we approve of him whom he imitates. But we disapprove not because he has not succeeded, but for wishing to succeed at all. For in the horse we approve of that to which by as much as we prefer man, by so much are we offended that he copies after inferior creatures. So among men, however well the crier may do in sending forth his voice, would not the senator be insane, if he should do it even more clearly and better than the crier? Take an illustration from the heavenly bodies: The moon when shining is praised, and by its course and its changes is quite pleasing to those that pay attention to such things. But if the sun should wish to imitate it (for we may feign that it has desires of this sort ), who would not be greatly and rightly displeased. From which illustrations I wish it to be understood, that even if there are souls (which meanwhile is left an open question ) devoted to bodily offices not by sin but by nature, and even if they are related to us, however inferior they may be, by some inner affinity, they should not be esteemed evil simply because we are evil ourselves in following them and in loving corporeal things. For we sin by loving corporeal things, because by justice we are required and by nature we are able to love spiritual things, and when we do this we are, in our kind, the best and the happiest.
21. Wherefore what proof does deliberation, violently urged in both directions, now prone to sin, now borne on toward right conduct, furnish, that we are compelled to accept two kinds of souls, the nature of one of which is from God, of the other not; when we are free to conjecture so many other causes of alternating states of mind? But that these things are obscure and are to no purpose pried into by blear-eyed minds, whoever is a good judge of things sees. Wherefore those things rather which have been said regarding the will and sin, those things, I say, that supreme justice permits no man using his reason to be ignorant of, those things which if they were taken from us, there is nothing whence the discipline of virtue may begin, nothing whence it may rise from the death of vices, those things I say considered again and again with sufficient clearness and lucidity convince us that the heresy of the Manichaeans is false.
