City of God, Book XII
What more useful than fire for warming, restoring, cooking, though nothing is more destructive than fire burning and consuming? The same thing, then, when applied in one way, is destructive, but when applied suitably, is most beneficial. For who can find words to tell its uses throughout the whole world? We must not listen, then, to those who praise the light of fire but find fault with its heat, judging it not by its nature, but by their convenience or discomfort. For they wish to see, but not to be burnt. But they forget that this very light which is so pleasant to them, disagrees with and hurts weak eyes; and in that heat which is disagreeable to them, some animals find the most suitable conditions of a healthy life.
Chapter 5.—That in All Natures, of Every Kind and Rank, God is Glorified.
All natures, then, inasmuch as they are, and have therefore a rank and species of their own, and a kind of internal harmony, are certainly good. And when they are in the places assigned to them by the order of their nature, they preserve such being as they have received. And those things which have not received everlasting being, are altered for better or for worse, so as to suit the wants and motions of those things to which the Creator’s law has made them subservient; and thus they tend in the divine providence to that end which is embraced in the general scheme of the government of the universe. So that, though the corruption of transitory and perishable things brings them to utter destruction, it does not prevent their producing that which was designed to be their result. And this being so, God, who supremely is, and who therefore created every being which has not supreme existence (for that which was made of nothing could not be equal to Him, and indeed could not be at all had He not made it), is not to be found fault with on account of the creature’s faults, but is to be praised in view of the natures He has made.
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—not 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 some one 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?”
