Whether the will of God imposes necessity on the things willed?
Objection 1: It seems that the will of God imposes necessity on the things willed. For Augustine says (Enchiridion 103): "No one is saved, except whom God has willed to be saved. He must therefore be asked to will it; for if He wills it, it must necessarily be."
Objection 2: Further, every cause that cannot be hindered, produces its effect necessarily, because, as the Philosopher says (Phys. ii, 84) "Nature always works in the same way, if there is nothing to hinder it." But the will of God cannot be hindered. For the Apostle says (Rom. 9:19): "Who resisteth His will?" Therefore the will of God imposes necessity on the things willed.
Objection 3: Further, whatever is necessary by its antecedent cause is necessary absolutely; it is thus necessary that animals should die, being compounded of contrary elements. Now things created by God are related to the divine will as to an antecedent cause, whereby they have necessity. For the conditional statement is true that if God wills a thing, it comes to pass; and every true conditional statement is necessary. It follows therefore that all that God wills is necessary absolutely.
On the contrary, All good things that exist God wills to be. If therefore His will imposes necessity on things willed, it follows that all good happens of necessity; and thus there is an end of free will, counsel, and all other such things.
I answer that, The divine will imposes necessity on some things willed but not on all. The reason of this some have chosen to assign to intermediate causes, holding that what God produces by necessary causes is necessary; and what He produces by contingent causes contingent.
This does not seem to be a sufficient explanation, for two reasons. First, because the effect of a first cause is contingent on account of the secondary cause, from the fact that the effect of the first cause is hindered by deficiency in the second cause, as the sun's power is hindered by a defect in the plant. But no defect of a secondary cause can hinder God's will from producing its effect. Secondly, because if the distinction between the contingent and the necessary is to be referred only to secondary causes, this must be independent of the divine intention and will; which is inadmissible. It is better therefore to say that this happens on account of the efficacy of the divine will. For when a cause is efficacious to act, the effect follows upon the cause, not only as to the thing done, but also as to its manner of being done or of being. Thus from defect of active power in the seed it may happen that a child is born unlike its father in accidental points, that belong to its manner of being. Since then the divine will is perfectly efficacious, it follows not only that things are done, which God wills to be done, but also that they are done in the way that He wills. Now God wills some things to be done necessarily, some contingently, to the right ordering of things, for the building up of the universe. Therefore to some effects He has attached necessary causes, that cannot fail; but to others defectible and contingent causes, from which arise contingent effects. Hence it is not because the proximate causes are contingent that the effects willed by God happen contingently, but because God prepared contingent causes for them, it being His will that they should happen contingently.
Reply to Objection 1: By the words of Augustine we must understand a necessity in things willed by God that is not absolute, but conditional. For the conditional statement that if God wills a thing it must necessarily be, is necessarily true.
Reply to Objection 2: From the very fact that nothing resists the divine will, it follows that not only those things happen that God wills to happen, but that they happen necessarily or contingently according to His will.
Reply to Objection 3: Consequents have necessity from their antecedents according to the mode of the antecedents. Hence things effected by the divine will have that kind of necessity that God wills them to have, either absolute or conditional. Not all things, therefore, are absolute necessities.
I · Q. 19, Art. 9: Whether God wills evils?
Whether God wills evils?
Objection 1: It seems that God wills evils. For every good that exists, God wills. But it is a good that evil should exist. For Augustine says (Enchiridion 95): "Although evil in so far as it is evil is not a good, yet it is good that not only good things should exist, but also evil things." Therefore God wills evil things.
Objection 2: Further, Dionysius says (Div. Nom. iv, 23): "Evil would conduce to the perfection of everything," i.e. the universe. And Augustine says (Enchiridion 10,11): "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." But God wills all that appertains to the perfection and beauty of the universe, for this is what God desires above all things in His creatures. Therefore God wills evil.
Objection 3: Further, that evil should exist, and should not exist, are contradictory opposites. 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.
I answer that, Since the ratio of good is the ratio of appetibility, as said before (Q 5, A 1), and since evil is opposed to good, it is impossible that any evil, as such, should be sought for by the appetite, either natural, or animal, or by the intellectual appetite which is the will. Nevertheless evil may be sought accidentally, so far as it accompanies a good, as appears in each of the appetites. 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. Similarly the fornicator has merely pleasure for his object, and the deformity of sin is only an accompaniment. 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. 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.
Reply to Objection 1: Some have said that although God does not will evil, yet He wills that evil should be or be done, because, although evil is not a good, yet it is good that evil should be or be done. This they said because things evil in themselves are ordered to some good end; and this order they thought was expressed in the words "that evil should be or be done." 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. It cannot therefore be said that such an ordering to good is implied in the statement that it is a good thing that evil should be or be done, since nothing is judged of by that which appertains to it accidentally, but by that which belongs to it essentially.
Reply to Objection 2: Evil does not operate towards the perfection and beauty of the universe, except accidentally, as said above (ad 1). Therefore Dionysius in saying that "evil would conduce to the perfection of the universe," draws a conclusion by reduction to an absurdity.
Reply to Objection 3: The statements that evil exists, and that evil exists not, are opposed as contradictories; yet the statements that anyone wills evil to exist and that he wills it not to be, are not so opposed; since either is affirmative. God therefore neither wills evil to be done, nor wills it not to be done, but wills to permit evil to be done; and this is a good.
