13. From this it follows that there is nothing to be called evil if there is nothing good. A good that wholly lacks an evil aspect is entirely good. Where there is some evil in a thing, its good is defective or defectible. Thus there can be no evil where there is no good. This leads us to a surprising conclusion: that, since every being, in so far as it is a being, is good, if we then say that a defective thing is bad, it would seem to mean that we are saying that what is evil is good, that only what is good is ever evil and that there is no evil apart from something good. This is because every actual entity is good [omnis natura bonum est.] Nothing evil exists in itself, but only as an evil aspect of some actual entity. Therefore, there can be nothing evil except something good. Absurd as this sounds, nevertheless the logical connections of the argument compel us to it as inevitable. At the same time, we must take warning lest we incur the prophetic judgment which reads: "Woe to those who call evil good and good evil: who call darkness light and light darkness; who call the bitter sweet and the sweet bitter."[23] Moreover the Lord himself saith: "An evil man brings forth evil out of the evil treasure of his heart."[24] What, then, is an evil man but an evil entity [natura mala], since man is an entity? Now, if a man is something good because he is an entity, what, then, is a bad man except an evil good? When, however, we distinguish between these two concepts, we find that the bad man is not bad because he is a man, nor is he good because he is wicked. Rather, he is a good entity in so far as he is a man, evil in so far as he is wicked. Therefore, if anyone says that simply to be a man is evil, or that to be a wicked man is good, he rightly falls under the prophetic judgment: "Woe to him who calls evil good and good evil." For this amounts to finding fault with God's work, because man is an entity of God's creation. It also means that we are praising the defects in this particular man because he is a wicked person. Thus, every entity, even if it is a defective one, in so far as it is an entity, is good. In so far as it is defective, it is evil.
14. Actually, then, in these two contraries we call evil and good, the rule of the logicians fails to apply.[25] No weather is both dark and bright at the same time; no food or drink is both sweet and sour at the same time; no body is, at the same time and place, both white and black, nor deformed and well-formed at the same time. This principle is found to apply in almost all disjunctions: two contraries cannot coexist in a single thing. Nevertheless, while no one maintains that good and evil are not contraries, they can not only coexist, but the evil cannot exist at all without the good, or in a thing that is not a good. On the other hand, the good can exist without evil. For a man or an angel could exist and yet not be wicked, whereas there cannot be wickedness except in a man or an angel. It is good to be a man, good to be an angel; but evil to be wicked. These two contraries are thus coexistent, so that if there were no good in what is evil, then the evil simply could not be, since it can have no mode in which to exist, nor any source from which corruption springs, unless it be something corruptible. Unless this something is good, it cannot be corrupted, because corruption is nothing more than the deprivation of the good. Evils, therefore, have their source in the good, and unless they are parasitic on something good, they are not anything at all. There is no other source whence an evil thing can come to be. If this is the case, then, in so far as a thing is an entity, it is unquestionably good. If it is an incorruptible entity, it is a great good. But even if it is a corruptible entity, it still has no mode of existence except as an aspect of something that is good. Only by corrupting something good can corruption inflict injury.
15. But when we say that evil has its source in the good, do not suppose that this denies our Lord's judgment: "A good tree cannot bear evil fruit."[26] This cannot be, even as the Truth himself declareth: "Men do not gather grapes from thorns," since thorns cannot bear grapes. Nevertheless, from good soil we can see both vines and thorns spring up. Likewise, just as a bad tree does not grow good fruit, so also an evil will does not produce good deeds. From a human nature, which is good in itself, there can spring forth either a good or an evil will. There was no other place from whence evil could have arisen in the first place except from the nature--good in itself--of an angel or a man. This is what our Lord himself most clearly shows in the passage about the trees and the fruits, for he said: "Make the tree good and the fruits will be good, or make the tree bad and its fruits will be bad."[27] This is warning enough that bad fruit cannot grow on a good tree nor good fruit on a bad one. Yet from that same earth to which he was referring, both sorts of trees can grow.
23. With this much said, within the necessary brevity of this kind of treatise, as to what we need to know about the causes of good and evil--enough to lead us in the way toward the Kingdom, where there will be life without death, truth without error, happiness without anxiety--we ought not to doubt in any way that the cause of everything pertaining to our good is nothing other than the bountiful goodness of God himself. The cause of evil is the defection of the will of a being who is mutably good from the Good which is immutable. This happened first in the case of the angels and, afterward, that of man.
24. This was the primal lapse of the rational creature, that is, his first privation of the good. In train of this there crept in, even without his willing it, ignorance of the right things to do and also an appetite for noxious things. And these brought along with them, as their companions, error and misery. When these two evils are felt to be imminent, the soul's motion in flight from them is called fear. Moreover, as the soul's appetites are satisfied by things harmful or at least inane--and as it fails to recognize the error of its ways--it falls victim to unwholesome pleasures or may even be exhilarated by vain joys. From these tainted springs of action--moved by the lash of appetite rather than a feeling of plenty--there flows out every kind of misery which is now the lot of rational natures.
25. Yet such a nature, even in its evil state, could not lose its appetite for blessedness. There are the evils that both men and angels have in common, for whose wickedness God hath condemned them in simple justice. But man has a unique penalty as well: he is also punished by the death of the body. God had indeed threatened man with death as penalty if he should sin. He endowed him with freedom of the will in order that he might rule him by rational command and deter him by the threat of death. He even placed him in the happiness of paradise in a sheltered nook of life [in umbra vitae] where, by being a good steward of righteousness, he would rise to better things.
26. From this state, after he had sinned, man was banished, and through his sin he subjected his descendants to the punishment of sin and damnation, for he had radically corrupted them, in himself, by his sinning. As a consequence of this, all those descended from him and his wife (who had prompted him to sin and who was condemned along with him at the same time)--all those born through carnal lust, on whom the same penalty is visited as for disobedience--all these entered into the inheritance of original sin. Through this involvement they were led, through divers errors and sufferings (along with the rebel angels, their corruptors and possessors and companions), to that final stage of punishment without end. "Thus by one man, sin entered into the world and death through sin; and thus death came upon all men, since all men have sinned."[44] By "the world" in this passage the apostle is, of course, referring to the whole human race.
27. This, then, was the situation: the whole mass of the human race stood condemned, lying ruined and wallowing in evil, being plunged from evil into evil and, having joined causes with the angels who had sinned, it was paying the fully deserved penalty for impious desertion. Certainly the anger of God rests, in full justice, on the deeds that the wicked do freely in blind and unbridled lust; and it is manifest in whatever penalties they are called on to suffer, both openly and secretly. Yet the Creator's goodness does not cease to sustain life and vitality even in the evil angels, for were this sustenance withdrawn, they would simply cease to exist. As for mankind, although born of a corrupted and condemned stock, he still retains the power to form and animate his seed, to direct his members in their temporal order, to enliven his senses in their spatial relations, and to provide bodily nourishment. For God judged it better to bring good out of evil than not to permit any evil to exist. And if he had willed that there should be no reformation in the case of men, as there is none for the wicked angels, would it not have been just if the nature that deserted God and, through the evil use of his powers, trampled and transgressed the precepts of his Creator, which could have been easily kept--the same creature who stubbornly turned away from His Light and violated the image of the Creator in himself, who had in the evil use of his free will broken away from the wholesome discipline of God's law--would it not have been just if such a being had been abandoned by God wholly and forever and laid under the everlasting punishment which he deserved? Clearly God would have done this if he were only just and not also merciful and if he had not willed to show far more striking evidence of his mercy by pardoning some who were unworthy of it.
30. But now, can that part of the human race to whom God hath promised deliverance and a place in the eternal Kingdom be restored through the merits of their own works? Of course not! For what good works could a lost soul do except as he had been rescued from his lostness? Could he do this by the determination of his free will? Of course not! For it was in the evil use of his free will that man destroyed himself and his will at the same time. For as a man who kills himself is still alive when he kills himself, but having killed himself is then no longer alive and cannot resuscitate himself after he has destroyed his own life--so also sin which arises from the action of the free will turns out to be victor over the will and the free will is destroyed. "By whom a man is overcome, to this one he then is bound as slave."[48] This is clearly the judgment of the apostle Peter. And since it is true, I ask you what kind of liberty can one have who is bound as a slave except the liberty that loves to sin?
He serves freely who freely does the will of his master. Accordingly he who is slave to sin is free to sin. But thereafter he will not be free to do right unless he is delivered from the bondage of sin and begins to be the servant of righteousness. This, then, is true liberty: the joy that comes in doing what is right. At the same time, it is also devoted service in obedience to righteous precept.
But how would a man, bound and sold, get back his liberty to do good, unless he could regain it from Him whose voice saith, "If the Son shall make you free, then you will be free indeed"[49]? But before this process begins in man, could anyone glory in his good works as if they were acts of his free will, when he is not yet free to act rightly? He could do this only if, puffed up in proud vanity, he were merely boasting. This attitude is what the apostle was reproving when he said, "By grace you have been saved by faith."[50]
31. And lest men should arrogate to themselves saving faith as their own work and not understand it as a divine gift, the same apostle who says somewhere else that he had "obtained mercy of the Lord to be trustworthy"[51] makes here an additional comment: "And this is not of yourselves, rather it is a gift of God--not because of works either, lest any man should boast."[52] But then, lest it be supposed that the faithful are lacking in good works, he added further, "For we are his workmanship, created in Christ Jesus to good works, which God hath prepared beforehand for us to walk in them."[53]
We are then truly free when God ordereth our lives, that is, formeth and createth us not as men--this he hath already done--but also as good men, which he is now doing by his grace, that we may indeed be new creatures in Christ Jesus.[54] Accordingly, the prayer: "Create in me a clean heart, O God."[55] This does not mean, as far as the natural human heart is concerned, that God hath not already created this.
32. Once again, lest anyone glory, if not in his own works, at least in the determination of his free will, as if some merit had originated from him and as if the freedom to do good works had been bestowed on him as a kind of reward, let him hear the same herald of grace, announcing: "For it is God who is at work in you both to will and to do according to his good will."[56] And, in another place: "It is not therefore a matter of man's willing, or of his running, but of God's showing mercy."[57] Still, it is obvious that a man who is old enough to exercise his reason cannot believe, hope, or love unless he wills it, nor could he run for the prize of his high calling in God without a decision of his will. In what sense, therefore, is it "not a matter of human willing or running but of God's showing mercy," unless it be that "the will itself is prepared by the Lord," even as it is written?[58] This saying, therefore, that "it is not a matter of human willing or running but of God's showing mercy," means that the action is from both, that is to say, from the will of man and from the mercy of God. Thus we accept the dictum, "It is not a matter of human willing or running but of God's showing mercy," as if it meant, "The will of man is not sufficient by itself unless there is also the mercy of God." By the same token, the mercy of God is not sufficient by itself unless there is also the will of man. But if we say rightly that "it is not a matter of human willing or running but of God's showing mercy," because the will of man alone is not enough, why, then, is not the contrary rightly said, "It is not a matter of God's showing mercy but of a man's willing," since the mercy of God by itself alone is not enough? Now, actually, no Christian would dare to say, "It is not a matter of God's showing mercy but of man's willing," lest he explicitly contradict the apostle. The conclusion remains, therefore, that this saying: "Not man's willing or running but God's showing mercy," is to be understood to mean that the whole process is credited to God, who both prepareth the will to receive divine aid and aideth the will which has been thus prepared.[59]
For a man's good will comes before many other gifts from God, but not all of them. One of the gifts it does not antedate is--just itself! Thus in the Sacred Eloquence we read both, "His mercy goes before me,"[60] and also, "His mercy shall follow me."[61] It predisposes a man before he wills, to prompt his willing. It follows the act of willing, lest one's will be frustrated. Otherwise, why are we admonished to pray for our enemies,[62] who are plainly not now willing to live piously, unless it be that God is even now at work in them and in their wills?[63] Or again, why are we admonished to ask in order to receive, unless it be that He who grants us what we will is he through whom it comes to pass that we will? We pray for enemies, therefore, that the mercy of God should go before them, as it goes before us; we pray for ourselves that his mercy shall follow us.
