FOURTH ARTICLE [I-II, Q. 10, Art. 4]

Whether the Will Is Moved of Necessity by the Exterior Mover Which Is

God?

Objection 1: It would seem that the will is moved of necessity by

God. For every agent that cannot be resisted moves of necessity. But

God cannot be resisted, because His power is infinite; wherefore it

is written (Rom. 9:19): "Who resisteth His will?" Therefore God moves

the will of necessity.

Obj. 2: Further, the will is moved of necessity to whatever it wills

naturally, as stated above (A. 2, ad 3). But "whatever God does in a

thing is natural to it," as Augustine says (Contra Faust. xxvi, 3).

Therefore the will wills of necessity everything to which God moves

it.

Obj. 3: Further, a thing is possible, if nothing impossible follows

from its being supposed. But something impossible follows from the

supposition that the will does not will that to which God moves it:

because in that case God's operation would be ineffectual. Therefore

it is not possible for the will not to will that to which God moves

it. Therefore it wills it of necessity.

_On the contrary,_ It is written (Ecclus. 15:14): "God made man from

the beginning, and left him in the hand of his own counsel."

Therefore He does not of necessity move man's will.

_I answer that,_ As Dionysius says (Div. Nom. iv) "it belongs to

Divine providence, not to destroy but to preserve the nature of

things." Wherefore it moves all things in accordance with their

conditions; so that from necessary causes through the Divine motion,

effects follow of necessity; but from contingent causes, effects

follow contingently. Since, therefore, the will is an active

principle, not determinate to one thing, but having an indifferent

relation to many things, God so moves it, that He does not determine

it of necessity to one thing, but its movement remains contingent and

not necessary, except in those things to which it is moved naturally.

Reply Obj. 1: The Divine will extends not only to the doing of

something by the thing which He moves, but also to its being done in

a way which is fitting to the nature of that thing. And therefore it

would be more repugnant to the Divine motion, for the will to be

moved of necessity, which is not fitting to its nature; than for it

to be moved freely, which is becoming to its nature.

Reply Obj. 2: That is natural to a thing, which God so works in it

that it may be natural to it: for thus is something becoming to a

thing, according as God wishes it to be becoming. Now He does not

wish that whatever He works in things should be natural to them, for

instance, that the dead should rise again. But this He does wish to

be natural to each thing--that it be subject to the Divine power.

Reply Obj. 3: If God moves the will to anything, it is incompatible

with this supposition, that the will be not moved thereto. But it is

not impossible simply. Consequently it does not follow that the will

is moved by God necessarily.
