Written in the early 5th century AD, The City of God is a cornerstone of Christian theology, presenting human history as a spiritual war between the Earthly City (the fallen City of Man) and the City of God. The Earthly City consists of those who devote themselves to the pleasures and concerns of the temporal world, while the City of God is marked by people who forego earthly desires in favor of dedicating themselves to the eternal truths of God. In Part II (Books XI-XXII, portions of which appear below), Augustine focuses on various issues related to the problem of evil, including the origins of the two cities; why some angels are good and some bad; an analysis of the creation and fall of man; and an exposition of the doctrine of original sin.
Book XI
Chapter 16: Of the Ranks and Differences of the Creatures, Estimated by Their Utility, or According to the Natural Gradations of Being
For, among those beings which exist, and which are not of God the Creator’s essence, those which have life are ranked above those which have none; those that have the power of generation, or even of desiring, above those which want this faculty. And, among things that have life, the sentient are higher than those which have no sensation, as animals are ranked above trees. And, among the sentient, the intelligent are above those that have not intelligence—men, e.g., above cattle. And, among the intelligent, the immortal such as the angels, above the mortal, such as men. These are the gradations according to the order of nature; but according to the utility each man finds in a thing, there are various standards of value, so that it comes to pass that we prefer some things that have no sensation to some sentient beings. And so strong is this preference, that, had we the power, we would abolish the latter from nature altogether, whether in ignorance of the place they hold in nature, or, though we know it, sacrificing them to our own convenience. Who, e.g., would not rather have bread in his house than mice, gold than fleas? But there is little to wonder at in this, seeing that even when valued by men themselves (whose nature is certainly of the highest dignity), more is often given for a horse than for a slave, for a jewel than for a maid. Thus, the reason of one contemplating nature prompts very different judgments from those dictated by the necessity of the needy, or the desire of the voluptuous; for the former considers what value a thing in itself has in the scale of creation, while necessity considers how it meets its need; reason looks for what the mental light will judge to be true, while pleasure looks for what pleasantly titilates the bodily sense. But of such consequence in rational natures is the weight, so to speak, of will and of love, that though in the order of nature angels rank above men, yet, by the scale of justice, good men are of greater value than bad angels.
Chapter 17: That the Flaw of Wickedness is Not Nature, But Contrary to Nature, and Has Its Origin, Not in the Creator, But in the Will
It is with reference to the nature, then, and not to the wickedness of the devil, that we are to understand these words, “This is the beginning of God’s handiwork;” for, without doubt, wickedness can be a flaw or vice only where the nature previously was not vitiated. Vice, too, is so contrary to nature, that it cannot but damage it. And therefore departure from God would be no vice, unless in a nature whose property it was to abide with God. So that even the wicked will is a strong proof of the goodness of the nature. But God, as He is the supremely good Creator of good natures, so is He of evil wills the most just Ruler; so that, while they make an ill use of good natures, He makes a good use even of evil wills. Accordingly, He caused the devil (good by God’s creation, wicked by his own will) to be cast down from his high position, and to become the mockery of His angels—that is, He caused his temptations to benefit those whom he wishes to injure by them. And because God, when He created him, was certainly not ignorant of his future malignity, and foresaw the good which He Himself would bring out of his evil, therefore says the psalm, “This leviathan whom Thou hast made to be a sport therein,” that we may see that, even while God in His goodness created him good, He yet had already foreseen and arranged how He would make use of him when he became wicked.
Chapter 22: Of Those Who Do Not Approve of Certain Things Which are a Part of This Good Creation of a Good Creator, and Who Think that There is Some Natural Evil
This cause, however, of a good creation, namely, the goodness of God—this cause, I say, so just and fit, which, when piously and carefully weighed, terminates all the controversies of those who inquire into the origin of the world, has not been recognized by some heretics, because there are, forsooth, many things, such as fire, frost, wild beasts, and so forth, which do not suit but injure this thin blooded and frail mortality of our flesh, which is at present under just punishment. They do not consider how admirable these things are in their own places, how excellent in their own natures, how beautifully adjusted to the rest of creation, and how much grace they contribute to the universe by their own contributions as to a commonwealth; and how serviceable they are even to ourselves, if we use them with a knowledge of their fit adaptations—so that even poisons, which are destructive when used injudiciously, become wholesome and medicinal when used in conformity with their qualities and design; just as, on the other hand, those things which give us pleasure, such as food, drink, and the light of the sun, are found to be hurtful when immoderately or unseasonably used. And thus divine providence admonishes us not foolishly to vituperate things, but to investigate their utility with care; and, where our mental capacity or infirmity is at fault, to believe that there is a utility, though hidden, as we have experienced that there were other things which we all but failed to discover. For this concealment of the use of things is itself either an exercise of our humility or a levelling of our pride; for no nature at all is evil, and this is a name for nothing but the want of good. But from things earthly to things heavenly, from the visible to the invisible, there are some things better than others; and for this purpose are they unequal, in order that they might all exist. Now God is in such sort a great worker in great things, that He is not less in little things—for these little things are to be measured not by their own greatness (which does not exist), but by the wisdom of their Designer; as, in the visible appearance of a man, if one eyebrow be shaved off, how nearly nothing is taken from the body, but how much from the beauty! —for that is not constituted by bulk, but by the proportion and arrangement of the members. But we do not greatly wonder that persons, who suppose that some evil nature has been generated and propagated by a kind of opposing principle proper to it, refuse to admit that the cause of the creation was this, that the good God produced a good creation. For they believe that He was driven to this enterprise of creation by the urgent necessity of repulsing the evil that warred against Him, and that He mixed His good nature with the evil for the sake of restraining and conquering it; and that this nature of His, being thus shamefully polluted, and most cruelly oppressed and held captive, He labors to cleanse and deliver it, and with all His pains does not wholly succeed; but such part of it as could not be cleansed from that defilement is to serve as a prison and chain of the conquered and incarcerated enemy. The Manichaeans would not drivel, or rather, rave in such a style as this, if they believed the nature of God to be, as it is, unchangeable and absolutely incorruptible, and subject to no injury; and if, moreover, they held in Christian sobriety, that the soul which has shown itself capable of being altered for the worse by its own will, and of being corrupted by sin, and so, of being deprived of the light of eternal truth—that this soul, I say, is not a part of God, nor of the same nature as God, but is created by Him, and is far different from its Creator.
Book XII
Chapter 6: What the Cause of the Blessedness of the Good Angels Is, and What the Cause of the Misery of the Wicked
Thus the true cause of the blessedness of the good angels is found to be this, that they cleave to Him who supremely is. And if we ask the cause of the misery of the bad, it occurs to us, and not unreasonably, that they are miserable because they have forsaken Him who supremely is, and have turned to themselves who have no such essence. And this vice, what else is it called than pride? For “pride is the beginning of sin.” They were unwilling, then, to preserve their strength for God; and as adherence to God was the condition of their enjoying an ampler being, they diminished it by preferring themselves to Him. This was the first defect, and the first impoverishment, and the first flaw of their nature, which was created, not indeed supremely existent, but finding its blessedness in the enjoyment of the Supreme Being; whilst by abandoning Him it should become, not indeed no nature at all, but a nature with a less ample existence, and therefore wretched.
If the further question be asked, What was the efficient cause of their evil will? There is none. For what is it which makes the will bad, when it is the will itself which makes the action bad? And consequently the bad will is the cause of the bad action, but nothing is the efficient cause of the bad will. For if anything is the cause, this thing either has or has not a will. If it has, the will is either good or bad. If good, who is so left to himself as to say that a good will makes a will bad? For in this case a good will would be the cause of sin; a most absurd supposition. On the other hand, if this hypothetical thing has a bad will, I wish to know what made it so; and that we may not go on forever, I ask at once, what made the first evil will bad? For that is not the first which was itself corrupted by an evil will, but that is the first which was made evil by no other will. For if it were preceded by that which made it evil, that will was first which made the other evil. But if it is replied, “Nothing made it evil; it always was evil,” I ask if it has been existing in some nature. For if not, then it did not exist at all; and if it did exist in some nature, then it vitiated and corrupted it, and injured it, and consequently deprived it of good. And therefore the evil will could not exist in an evil nature, but in a nature at once good and mutable, which this vice could injure. For if it did no injury, it was no vice; and consequently the will in which it was, could not be called evil. But if it did injury, it did it by taking away or diminishing good. And therefore there could not be from eternity, as was suggested, an evil will in that thing in which there had been previously a natural good, which the evil will was able to diminish by corrupting it. If, then, it was not from eternity, who, I ask, made it? The only thing that can be suggested in reply is, that something which itself had no will, made the will evil. I ask, then, whether this thing was superior, inferior, or equal to it? If superior, then it is better. How, then, has it no will, and not rather a good will? The same reasoning applies if it was equal; for so long as two things have equally a good will, the one cannot produce in the other an evil will. Then remains the supposition that that which corrupted the will of the angelic nature which first sinned, was itself an inferior thing without a will. But that thing, be it of the lowest and most earthly kind, is certainly itself good, since it is a nature and being, with a form and rank of its own in its own kind and order. How, then, can a good thing be the efficient cause of an evil will? How, I say, can good be the cause of evil? For when the will abandons what is above itself, and turns to what is lower, it becomes evil—it because that is evil to which it turns, but because the turning itself is wicked. Therefore it is not an inferior thing which has made the will evil, but it is itself which has become so by wickedly and inordinately desiring an inferior thing. For if two men, alike in physical and moral constitution, see the same corporal beauty, and one of them is excited by the sight to desire an illicit enjoyment while the other steadfastly maintains a modest restraint of his will, what do we suppose brings it about, that there is an evil will in the one and not in the other? What produces it in the man in whom it exists? Not the bodily beauty, for that was presented equally to the gaze of both, and yet did not produce in both an evil will. Did the flesh of the one cause the desire as he looked? But why did not the flesh of the other? Or was it the disposition? But why not the disposition of both? For we are supposing that both were of a like temperament of body and soul. Must we, then, say that the one was tempted by a secret suggestion of the evil spirit? As if it was not by his own will that he consented to this suggestion and to any inducement whatever! This consent, then, this evil will which he presented to the evil suasive influence—what was the cause of it, we ask? For, not to delay on such a difficulty as this, if both are tempted equally and one yields and consents to the temptation while the other remains unmoved by it, what other account can we give of the matter than this, that the one is willing, the other unwilling, to fall away from chastity? And what causes this but their own wills, in cases at least such as we are supposing, where the temperament is identical? The same beauty was equally obvious to the eyes of both; the same secret temptation pressed on both with equal violence. However minutely we examine the case, therefore, we can discern nothing which caused the will of the one to be evil. For if we say that the man himself made his will evil, what was the man himself before his will was evil but a good nature created by God, the unchangeable good? Here are two men who, before the temptation, were alike in body and soul, and of whom one yielded to the tempter who persuaded him, while the other could not be persuaded to desire that lovely body which was equally before the eyes of both. Shall we say of the successfully tempted man that he corrupted his own will, since he was certainly good before his will became bad? Then, why did he do so? Was it because his will was a nature, or because it was made of nothing? We shall find that the latter is the case. For if a nature is the cause of an evil will, what else can we say than that evil arises from good or that good is the cause of evil? And how can it come to pass that a nature, good though mutable, should produce any evil—that is to say, should make the will itself wicked?
Chapter 7: That We Ought Not to Expect to Find Any Efficient Cause of the Evil Will
Let no one, therefore, look for an efficient cause of the evil will; for it is not efficient, but deficient, as the will itself is not an effecting of something, but a defect. For defection from that which supremely is, to that which has less of being—this is to begin to have an evil will. Now, to seek to discover the causes of these defections—causes, as I have said, not efficient, but deficient—is as if someone sought to see darkness, or hear silence. Yet both of these are known by us, and the former by means only of the eye, the latter only by the ear; but not by their positive actuality, but by their want of it. Let no one, then seek to know from me what I know that I do not know; unless he perhaps wishes to learn to be ignorant of that of which all we know is, that it cannot be known. For those things which are known not by their actuality, but by their want of it, are known, if our expression may be allowed and understood, by not knowing them, that by knowing them they may be not known. For when the eyesight surveys objects that strike the sense, it nowhere sees darkness but where it begins not to see. And so no other sense but the ear can perceive silence, and yet it is only perceived by not hearing. Thus, too, our mind perceives intelligible forms by understanding them; but when they are deficient, it knows them by not knowing them; for “who can understand defects?”
Chapter 8: Of the Misdirected Love Whereby the Will Fell Away from the Immutable to the Mutable Good
This I do know, that the nature of God can never, nowhere, nowise be defective, and that natures made of nothing can. These latter, however, the more being they have, and the more good they do (for then they do something positive), the more they have efficient causes; but in so far as they are defective in being, and consequently do evil (for then what is their work but vanity?), they have deficient causes. And I know likewise, that the will could not become evil, were it unwilling to become so; and therefore its failings are justly punished, being not necessary, but voluntary. For its defections are not to evil things, but are themselves evil; that is to say, are not towards things that are naturally and in themselves evil, but the defection of the will is evil, because it is contrary to the order of nature, and an abandonment of that which has supreme being for that which has less. For avarice is not a fault inherent in gold, but in the man who inordinately loves gold, to the detriment of justice, which ought to be held in incomparably higher regard than gold. Neither is luxury the fault of lovely and charming objects, but of the heart that inordinately loves sensual pleasures, to the neglect of temperance, which attaches us to objects more lovely in their spirituality, and more delectable by their incorruptibility. Nor yet is boasting the fault of human praise, but of the soul that is inordinately fond of the applause of men, and that makes light of the voice of conscience. Pride, too, is not the fault of him who delegates power, nor of power itself, but of the soul that is inordinately enamored of its own power, and despises the more just dominion of a higher authority. Consequently, he who inordinately loves the good which any nature possesses, even though he obtain it, himself becomes evil in the good, and wretched because deprived of a greater good.
