Thomas Aquinas

“ But God does not will that evil should not exist; otherwise, since various evils do exist, God's will would not always be fulfilled. Therefore God wills that evil should exist.
On the contrary, Augustine says (Qq. 83,3) : "No wise man is the cause of another man becoming worse. Now God surpasses all men in wisdom. Much less therefore is God the cause of man becoming worse; and when He is said to be the cause of a thing, He is said to will it." Therefore it is not by God's will that man becomes worse. Now it is clear that every evil makes a thing worse. Therefore God wills not evil things. ”

“ But God wills things apart from Himself in so far as they are ordered to His own goodness as their end. Now in willing an end we do not necessarily will things that conduce to it, unless they are such that the end cannot be attained without them; as, we will to take food to preserve life, or to take ship in order to cross the sea. But we do not necessarily will things without which the end is attainable, such as a horse for a journey which we can take on foot, for we can make the journey without one. ”

“ For when we say that God exists, no relation to any other object is implied, as we do imply when we say that God wills. Therefore, although He is not anything apart from Himself, yet He does will things apart from Himself. ”

“ Since, then, the will of God is the universal cause of all things, it is impossible that the divine will should not produce its effect. Hence that which seems to depart from the divine will in one order, returns into it in another order; as does the sinner, who by sin falls away from the divine will as much as lies in him, yet falls back into the order of that will, when by its justice he is punished. ”

“ I answer that, There is will in God, as there is intellect: since will follows upon intellect. For as natural things have actual existence by their form, so the intellect is actually intelligent by its intelligible form. Now everything has this aptitude towards its natural form, that when it has it not, it tends towards it; and when it has it, it is at rest therein. It is the same with every natural perfection, which is a natural good. This aptitude to good in things without knowledge is called natural appetite. ”

“ Now God wills no good more than He wills His own goodness; yet He wills one good more than another. Hence He in no way wills the evil of sin, which is the privation of right order towards the divine good. The evil of natural defect, or of punishment, He does will, by willing the good to which such evils are attached. Thus in willing justice He wills punishment; and in willing the preservation of the natural order, He wills some things to be naturally corrupted. ”

“ This distinction must not be taken as applying to the divine will itself, in which there is nothing antecedent nor consequent, but to the things willed.
To understand this we must consider that everything, in so far as it is good, is willed by God. A thing taken in its primary sense, and absolutely considered, may be good or evil, and yet when some additional circumstances are taken into account, by a consequent consideration may be changed into the contrary. Thus that a man should live is good; and that a man should be killed is evil, absolutely considered. ”

“ It is not right therefore to assign one expression only in the case of evil---namely, prohibition---and two---namely, counsel and precept---in the case of good.
I answer that, By these signs we name the expression of will by which we are accustomed to show that we will something. A man may show that he wills something, either by himself or by means of another. He may show it by himself, by doing something either directly, or indirectly and accidentally. He shows it directly when he works in his own person; in that way the expression of his will is his own working. ”

“ Since God wills effects to come from causes, all effects that presuppose some other effect do not depend solely on the will of God, but on something else besides: but the first effect depends on the divine will alone. Thus, for example, we may say that God willed man to have hands to serve his intellect by their work, and intellect, that he might be man; and willed him to be man that he might enjoy Him, or for the completion of the universe. But this cannot be reduced to other created secondary ends. Hence such things depend on the simple will of God ”

“ Thus it may be said that a just judge wills simply the hanging of a murderer, but in a qualified manner he would will him to live, to wit, inasmuch as he is a man. Such a qualified will may be called a willingness rather than an absolute will. ”

“ This cannot be the case if in one act he wills both end and means; for a thing cannot be its own cause. Yet it will be true to say that he wills to order to the end the means to the end. Now as God by one act understands all things in His essence, so by one act He wills all things in His goodness. Hence, as in God to understand the cause is not the cause of His understanding the effect, for He understands the effect in the cause, so, in Him, to will an end is not the cause of His willing the means, yet He wills the ordering of the means to the end. ”

“ Even in us the cause of one and the same effect is knowledge as directing it, whereby the form of the work is conceived, and will as commanding it, since the form as it is in the intellect only is not determined to exist or not to exist in the effect, except by the will. Hence, the speculative intellect has nothing to say to operation. But the power is cause, as executing the effect, since it denotes the immediate principle of operation. But in God all these things are one. ”

“ Out of all things is built up the admirable beauty of the universe, wherein even that which is called evil, properly ordered and disposed, commends the good more evidently in that good is more pleasing and praiseworthy when contrasted with evil. ”

“ Will in us belongs to the appetitive part, which, although named from appetite, has not for its only act the seeking what it does not possess; but also the loving and the delighting in what it does possess. In this respect will is said to be in God, as having always good which is its object, since, as already said, it is not distinct from His essence. ”

“ Expressions of will are called divine wills, not as being signs that God wills anything; but because what in us is the usual expression of our will, is called the divine will in God. Thus punishment is not a sign that there is anger in God ”

“ Hence, since God is first in the order of agents, He must act by intellect and will.
This is shown, secondly, from the character of a natural agent, of which the property is to produce one and the same effect; for nature operates in one and the same way unless it be prevented. This is because the nature of the act is according to the nature of the agent; and hence as long as it has that nature, its acts will be in accordance with that nature; for every natural agent has a determinate being. ”

“ In things willed for the sake of the end, the whole reason for our being moved is the end, and this it is that moves the will, as most clearly appears in things willed only for the sake of the end. He who wills to take a bitter draught, in doing so wills nothing else than health ”

“ It seems that five expressions of will---namely, prohibition, precept, counsel, operation, and permission---are not rightly assigned to the divine will. For the same things that God bids us do by His precept or counsel, these He sometimes operates in us, and the same things that He prohibits, these He sometimes permits. ”

“ Rational creatures are masters of their own acts; and for this reason certain special expressions of the divine will are assigned to their acts, inasmuch as God ordains rational creatures to act voluntarily and of themselves. Other creatures act only as moved by the divine operation ”

“ Now the evil that accompanies one good, is the privation of another good. Never therefore would evil be sought after, not even accidentally, unless the good that accompanies the evil were more desired than the good of which the evil is the privation. ”

“ For a natural agent intends not privation or corruption, but the form to which is annexed the privation of some other form, and the generation of one thing, which implies the corruption of another. Also when a lion kills a stag, his object is food, to obtain which the killing of the animal is only the means. ”

“ But if in a particular case we add that a man is a murderer or dangerous to society, to kill him is a good; that he live is an evil. Hence it may be said of a just judge, that antecedently he wills all men to live ”

“ This, however, is not correct; since evil is not of itself ordered to good, but accidentally. For it is beside the intention of the sinner, that any good should follow from his sin; as it was beside the intention of tyrants that the patience of the martyrs should shine forth from all their persecutions. ”
