FIFTH ARTICLE [I, Q. 45, Art. 5]

Whether It Belongs to God Alone to Create?

Objection 1: It would seem that it does not belong to God alone to

create, because, according to the Philosopher (De Anima ii, text 34),

what is perfect can make its own likeness. But immaterial creatures

are more perfect than material creatures, which nevertheless can make

their own likeness, for fire generates fire, and man begets man.

Therefore an immaterial substance can make a substance like to itself.

But immaterial substance can be made only by creation, since it has no

matter from which to be made. Therefore a creature can create.

Obj. 2: Further, the greater the resistance is on the part of the

thing made, so much the greater power is required in the maker. But

a "contrary" resists more than "nothing." Therefore it requires more

power to make (something) from its contrary, which nevertheless a

creature can do, than to make a thing from nothing. Much more

therefore can a creature do this.

Obj. 3: Further, the power of the maker is considered according to

the measure of what is made. But created being is finite, as we

proved above when treating of the infinity of God (Q. 7, AA. 2, 3,

4). Therefore only a finite power is needed to produce a creature by

creation. But to have a finite power is not contrary to the nature of

a creature. Therefore it is not impossible for a creature to create.

_On the contrary,_ Augustine says (De Trin. iii, 8) that neither good

nor bad angels can create anything. Much less therefore can any other

creatures.

_I answer that,_ It sufficiently appears at the first glance,

according to what precedes (A. 1), that to create can be the action

of God alone. For the more universal effects must be reduced to the

more universal and prior causes. Now among all effects the most

universal is being itself: and hence it must be the proper effect of

the first and most universal cause, and that is God. Hence also it is

said (De Causis prop., iii) that "neither intelligence nor the soul

gives us being, except inasmuch as it works by divine operation." Now

to produce being absolutely, not as this or that being, belongs to

creation. Hence it is manifest that creation is the proper act of God

alone.

It happens, however, that something participates the proper action of

another, not by its own power, but instrumentally, inasmuch as it acts

by the power of another; as air can heat and ignite by the power of

fire. And so some have supposed that although creation is the proper

act of the universal cause, still some inferior cause acting by the

power of the first cause, can create. And thus Avicenna asserted that

the first separate substance created by God created another after

itself, and the substance of the world and its soul; and that the

substance of the world creates the matter of inferior bodies. And in

the same manner the Master says (Sent. iv, D, 5) that God can

communicate to a creature the power of creating, so that the latter

can create ministerially, not by its own power.

But such a thing cannot be, because the secondary instrumental cause

does not participate the action of the superior cause, except inasmuch

as by something proper to itself it acts dispositively to the effect

of the principal agent. If therefore it effects nothing, according to

what is proper to itself, it is used to no purpose; nor would there be

any need of certain instruments for certain actions. Thus we see that

a saw, in cutting wood, which it does by the property of its own form,

produces the form of a bench, which is the proper effect of the

principal agent. Now the proper effect of God creating is what is

presupposed to all other effects, and that is absolute being. Hence

nothing else can act dispositively and instrumentally to this effect,

since creation is not from anything presupposed, which can be disposed

by the action of the instrumental agent. So therefore it is impossible

for any creature to create, either by its own power or

instrumentally--that is, ministerially.

And above all it is absurd to suppose that a body can create, for no

body acts except by touching or moving; and thus it requires in its

action some pre-existing thing, which can be touched or moved, which

is contrary to the very idea of creation.

Reply Obj. 1: A perfect thing participating any nature, makes a

likeness to itself, not by absolutely producing that nature, but by

applying it to something else. For an individual man cannot be the

cause of human nature absolutely, because he would then be the cause

of himself; but he is the cause of human nature being in the man

begotten; and thus he presupposes in his action a determinate matter

whereby he is an individual man. But as an individual man

participates human nature, so every created being participates, so to

speak, the nature of being; for God alone is His own being, as we

have said above (Q. 7, AA. 1, 2). Therefore no created being can

produce a being absolutely, except forasmuch as it causes "being" in

"this": and so it is necessary to presuppose that whereby a thing is

this thing, before the action whereby it makes its own likeness. But

in an immaterial substance it is not possible to presuppose anything

whereby it is this thing; because it is what it is by its form,

whereby it has being, since it is a subsisting form. Therefore an

immaterial substance cannot produce another immaterial substance like

to itself as regards its being, but only as regards some added

perfection; as we may say that a superior angel illuminates an

inferior, as Dionysius says (Coel. Hier. iv, x). In this way even in

heaven there is paternity, as the Apostle says (Eph. 3:15): "From

whom all paternity in heaven and on earth is named." From which

evidently appears that no created being can cause anything, unless

something is presupposed; which is against the very idea of creation.

Reply Obj. 2: A thing is made from its contrary indirectly (Phys. i,

text 43), but directly from the subject which is in potentiality. And

so the contrary resists the agent, inasmuch as it impedes the

potentiality from the act which the agent intends to induce, as fire

intends to reduce the matter of water to an act like to itself, but

is impeded by the form and contrary dispositions, whereby the

potentiality (of the water) is restrained from being reduced to act;

and the more the potentiality is restrained, the more power is

required in the agent to reduce the matter to act. Hence a much

greater power is required in the agent when no potentiality

pre-exists. Thus therefore it appears that it is an act of much

greater power to make a thing from nothing, than from its contrary.

Reply Obj. 3: The power of the maker is reckoned not only from the

substance of the thing made, but also from the mode of its being

made; for a greater heat heats not only more, but quicker. Therefore

although to create a finite effect does not show an infinite power,

yet to create it from nothing does show an infinite power: which

appears from what has been said (ad 2). For if a greater power is

required in the agent in proportion to the distance of the

potentiality from the act, it follows that the power of that which

produces something from no presupposed potentiality is infinite,

because there is no proportion between "no potentiality" and the

potentiality presupposed by the power of a natural agent, as there is

no proportion between "not being" and "being." And because no

creature has simply an infinite power, any more than it has an

infinite being, as was proved above (Q. 7, A. 2), it follows that no

creature can create.
