SECOND ARTICLE [I, Q. 47, Art. 2]

Whether the Inequality of Things Is from God?

Objection 1: It would seem that the inequality of things is not from

God. For it belongs to the best to produce the best. But among things

that are best, one is not greater than another. Therefore, it belongs

to God, Who is the Best, to make all things equal.

Obj. 2: Further, equality is the effect of unity (Metaph. v, text

20). But God is one. Therefore, He has made all things equal.

Obj. 3: Further, it is the part of justice to give unequal to unequal

things. But God is just in all His works. Since, therefore, no

inequality of things is presupposed to the operation whereby He gives

being to things, it seems that He has made all things equal.

_On the contrary,_ It is said (Ecclus. 33:7): "Why does one day excel

another, and one light another, and one year another year, one sun

another sun? [Vulg.: 'when all come of the sun']. By the knowledge of

the Lord they were distinguished."

_I answer that,_ When Origen wished to refute those who said that the

distinction of things arose from the contrary principles of good and

evil, he said that in the beginning all things were created equal by

God. For he asserted that God first created only the rational

creatures and all equal; and that inequality arose in them from

free-will, some being turned to God more and some less, and others

turned more and others less away from God. And so those rational

creatures which were turned to God by free-will, were promoted to the

order of angels according to the diversity of merits. And those who

were turned away from God were bound down to bodies according to the

diversity of their sin; and he said this was the cause of the creation

and diversity of bodies. But according to this opinion, it would

follow that the universality of bodily creatures would not be the

effect of the goodness of God as communicated to creatures, but it

would be for the sake of the punishment of sin, which is contrary to

what is said: "God saw all the things that He had made, and they were

very good" (Gen. 1:31). And, as Augustine says (De Civ. Dei ii, 3):

"What can be more foolish than to say that the divine Architect

provided this one sun for the one world, not to be an ornament to its

beauty, nor for the benefit of corporeal things, but that it happened

through the sin of one soul; so that, if a hundred souls had sinned,

there would be a hundred suns in the world?"

Therefore it must be said that as the wisdom of God is the cause of

the distinction of things, so the same wisdom is the cause of their

inequality. This may be explained as follows. A twofold distinction

is found in things; one is a formal distinction as regards things

differing specifically; the other is a material distinction as regards

things differing numerically only. And as the matter is on account

of the form, material distinction exists for the sake of the formal

distinction. Hence we see that in incorruptible things there is only

one individual of each species, forasmuch as the species is

sufficiently preserved in the one; whereas in things generated and

corruptible there are many individuals of one species for the

preservation of the species. Whence it appears that formal distinction

is of greater consequence than material. Now, formal distinction

always requires inequality, because as the Philosopher says (Metaph.

viii, 10), the forms of things are like numbers in which species vary

by addition or subtraction of unity. Hence in natural things species

seem to be arranged in degrees; as the mixed things are more perfect

than the elements, and plants than minerals, and animals than plants,

and men than other animals; and in each of these one species is more

perfect than others. Therefore, as the divine wisdom is the cause of

the distinction of things for the sake of the perfection of the

universe, so it is the cause of inequality. For the universe would not

be perfect if only one grade of goodness were found in things.

Reply Obj. 1: It is part of the best agent to produce an effect which

is best in its entirety; but this does not mean that He makes every

part of the whole the best absolutely, but in proportion to the

whole; in the case of an animal, for instance, its goodness would be

taken away if every part of it had the dignity of an eye. Thus,

therefore, God also made the universe to be best as a whole,

according to the mode of a creature; whereas He did not make each

single creature best, but one better than another. And therefore we

find it said of each creature, "God saw the light that it was good"

(Gen. 1:4); and in like manner of each one of the rest. But of all

together it is said, "God saw all the things that He had made, and

they were very good" (Gen. 1:31).

Reply Obj. 2: The first effect of unity is equality; and then comes

multiplicity; and therefore from the Father, to Whom, according to

Augustine (De Doctr. Christ. i, 5), is appropriated unity, the Son

proceeds to Whom is appropriated equality, and then from Him the

creature proceeds, to which belongs inequality; but nevertheless

even creatures share in a certain equality--namely, of proportion.

Reply Obj. 3: This is the argument that persuaded Origen: but it

holds only as regards the distribution of rewards, the inequality of

which is due to unequal merits. But in the constitution of things

there is no inequality of parts through any preceding inequality,

either of merits or of the disposition of the matter; but inequality

comes from the perfection of the whole. This appears also in works

done by art; for the roof of a house differs from the foundation, not

because it is made of other material; but in order that the house may

be made perfect of different parts, the artificer seeks different

material; indeed, he would make such material if he could.
