QUESTION 72

ON THE WORK OF THE SIXTH DAY

(In One Article)

We must now consider the work of the sixth day.

Objection 1: It would seem that this work is not fittingly described.

For as birds and fishes have a living soul, so also have land animals.

But these animals are not themselves living souls. Therefore the

words, "Let the earth bring forth the living creature," should rather

have been, "Let the earth bring forth the living four-footed

creatures."

Obj. 2: Further, a genus ought not to be opposed to its species. But

beasts and cattle are quadrupeds. Therefore quadrupeds ought not to

be enumerated as a class with beasts and cattle.

Obj. 3: Further, as animals belong to a determinate genus and

species, so also does man. But in the making of man nothing is said

of his genus and species, and therefore nothing ought to have been

said about them in the production of other animals, whereas it is

said "according to its genus" and "in its species."

Obj. 4: Further, land animals are more like man, whom God is recorded

to have blessed, than are birds and fishes. But as birds and fishes

are said to be blessed, this should have been said, with much more

reason, of the other animals as well.

Obj. 5: Further, certain animals are generated from putrefaction,

which is a kind of corruption. But corruption is repugnant to the

first founding of the world. Therefore such animals should not have

been produced at that time.

Obj. 6: Further, certain animals are poisonous, and injurious to man.

But there ought to have been nothing injurious to man before man

sinned. Therefore such animals ought not to have been made by God at

all, since He is the Author of good; or at least not until man had

sinned.

_On the contrary,_ Suffices the authority of Scripture.

_I answer that,_ As on the fifth day the intermediate body, namely, the

water, is adorned, and thus that day corresponds to the second day; so

the sixth day, on which the lowest body, or the earth, is adorned by

the production of land animals, corresponds to the third day. Hence

the earth is mentioned in both places. And here again Augustine says

(Gen. ad lit. v) that the production was potential, and other holy

writers that it was actual.

Reply Obj. 1: The different grades of life which are found in

different living creatures can be discovered from the various ways in

which Scripture speaks of them, as Basil says (Hom. viii in Hexaem.).

The life of plants, for instance, is very imperfect and difficult to

discern, and hence, in speaking of their production, nothing is said

of their life, but only their generation is mentioned, since only in

generation is a vital act observed in them. For the powers of

nutrition and growth are subordinate to the generative life, as will

be shown later on (Q. 78, A. 2). But amongst animals, those that

live on land are, generally speaking, more perfect than birds and

fishes, not because the fish is devoid of memory, as Basil upholds

(Hom. viii in Hexaem.) and Augustine rejects (Gen. ad lit. iii), but

because their limbs are more distinct and their generation of a higher

order, (yet some imperfect animals, such as bees and ants, are more

intelligent in certain ways). Scripture, therefore, does not call

fishes "living creatures," but "creeping creatures having life";

whereas it does call land animals "living creatures" on account of

their more perfect life, and seems to imply that fishes are merely

bodies having in them something of a soul, whilst land animals, from

the higher perfection of their life, are, as it were, living souls

with bodies subject to them. But the life of man, as being the most

perfect grade, is not said to be produced, like the life of other

animals, by earth or water, but immediately by God.

Reply Obj. 2: By "cattle," domestic animals are signified, which in

any way are of service to man: but by "beasts," wild animals such as

bears and lions are designated. By "creeping things" those animals

are meant which either have no feet and cannot rise from the earth,

as serpents, or those whose feet are too short to lift them far from

the ground, as the lizard and tortoise. But since certain animals, as

deer and goats, seem to fall under none of these classes, the word

"quadrupeds" is added. Or perhaps the word "quadruped" is used first

as being the genus, to which the others are added as species, for

even some reptiles, such as lizards and tortoises, are four-footed.

Reply Obj. 3: In other animals, and in plants, mention is made of

genus and species, to denote the generation of like from like. But it

was unnecessary to do so in the case of man, as what had already been

said of other creatures might be understood of him. Again, animals

and plants may be said to be produced according to their kinds, to

signify their remoteness from the Divine image and likeness, whereas

man is said to be made "to the image and likeness of God."

Reply Obj. 4: The blessing of God gives power to multiply by

generation, and, having been mentioned in the preceding account of

the making of birds and fishes, could be understood of the beasts of

the earth, without requiring to be repeated. The blessing, however,

is repeated in the case of man, since in him generation of children

has a special relation to the number of the elect [*Cf. Augustine,

Gen. ad lit. iii, 12], and to prevent anyone from saying that there

was any sin whatever in the act of begetting children. As to plants,

since they experience neither desire of propagation, nor sensation

in generating, they are deemed unworthy of a formal blessing.

Reply Obj. 5: Since the generation of one thing is the corruption of

another, it was not incompatible with the first formation of things,

that from the corruption of the less perfect the more perfect should

be generated. Hence animals generated from the corruption of

inanimate things, or of plants, may have been generated then. But

those generated from corruption of animals could not have been

produced then otherwise than potentially.

Reply Obj. 6: In the words of Augustine (Super. Gen. contr. Manich.

i): "If an unskilled person enters the workshop of an artificer he

sees in it many appliances of which he does not understand the use,

and which, if he is a foolish fellow, he considers unnecessary.

Moreover, should he carelessly fall into the fire, or wound himself

with a sharp-edged tool, he is under the impression that many of the

things there are hurtful; whereas the craftsman, knowing their use,

laughs at his folly. And thus some people presume to find fault with

many things in this world, through not seeing the reasons for their

existence. For though not required for the furnishing of our house,

these things are necessary for the perfection of the universe." And,

since man before he sinned would have used the things of this world

conformably to the order designed, poisonous animals would not have

injured him.
