FOURTH ARTICLE [I-II, Q. 6, Art. 4]

Whether Violence Can Be Done to the Will?

Objection 1: It would seem that violence can be done to the will. For

everything can be compelled by that which is more powerful. But there

is something, namely, God, that is more powerful than the human will.

Therefore it can be compelled, at least by Him.

Obj. 2: Further, every passive subject is compelled by its active

principle, when it is changed by it. But the will is a passive force:

for it is a "mover moved" (De Anima iii, 10). Therefore, since it is

sometimes moved by its active principle, it seems that sometimes it

is compelled.

Obj. 3: Further, violent movement is that which is contrary to

nature. But the movement of the will is sometimes contrary to nature;

as is clear of the will's movement to sin, which is contrary to

nature, as Damascene says (De Fide Orth. iv, 20). Therefore the

movement of the will can be compelled.

_On the contrary,_ Augustine says (De Civ. Dei v, 10) that what is

done by the will is not done of necessity. Now, whatever is done under

compulsion is done of necessity: consequently what is done by the

will, cannot be compelled. Therefore the will cannot be compelled to

act.

_I answer that,_ The act of the will is twofold: one is its immediate

act, as it were, elicited by it, namely, "to wish"; the other is an

act of the will commanded by it, and put into execution by means of

some other power, such as "to walk" and "to speak," which are

commanded by the will to be executed by means of the motive power.

As regards the commanded acts of the will, then, the will can suffer

violence, in so far as violence can prevent the exterior members from

executing the will's command. But as to the will's own proper act,

violence cannot be done to the will.

The reason of this is that the act of the will is nothing else than

an inclination proceeding from the interior principle of knowledge:

just as the natural appetite is an inclination proceeding from an

interior principle without knowledge. Now what is compelled or

violent is from an exterior principle. Consequently it is contrary to

the nature of the will's own act, that it should be subject to

compulsion and violence: just as it is also contrary to the nature of

a natural inclination or movement. For a stone may have an upward

movement from violence, but that this violent movement be from its

natural inclination is impossible. In like manner a man may be

dragged by force: but it is contrary to the very notion of violence,

that he be dragged of his own will.

Reply Obj. 1: God Who is more powerful than the human will, can move

the will of man, according to Prov. 21:1: "The heart of the king is

in the hand of the Lord; whithersoever He will He shall turn it." But

if this were by compulsion, it would no longer be by an act of the

will, nor would the will itself be moved, but something else against

the will.

Reply Obj. 2: It is not always a violent movement, when a passive

subject is moved by its active principle; but only when this is done

against the interior inclination of the passive subject. Otherwise

every alteration and generation of simple bodies would be unnatural

and violent: whereas they are natural by reason of the natural

interior aptitude of the matter or subject to such a disposition. In

like manner when the will is moved, according to its own inclination,

by the appetible object, this movement is not violent but voluntary.

Reply Obj. 3: That to which the will tends by sinning, although in

reality it is evil and contrary to the rational nature, nevertheless

is apprehended as something good and suitable to nature, in so far as

it is suitable to man by reason of some pleasurable sensation or some

vicious habit.
