NINTH ARTICLE [I, Q. 19, Art. 8]

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.

Obj. 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.

Obj. 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 Obj. 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 Obj. 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 Obj. 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.
