Thomas Aquinas - Summa Theologica, Part I-II (Pars Prima Secundae)

But a man's will is not right in willing a particular good, unless he refer it to the common good as an end: since even the natural appetite of each part is ordained to the common good of the whole. Now it is the end that supplies the formal reason, as it were, of willing whatever is directed to the end. Consequently, in order that a man will some particular good with a right will, he must will that particular good materially, and the Divine and universal good, formally. Therefore the human will is bound to be conformed to the Divine will, as to that which is willed formally, for it is bound to will the Divine and universal good; but not as to that which is willed materially, for the reason given above.

At the same time in both these respects, the human will is conformed to the Divine, in a certain degree. Because inasmuch as it is conformed to the Divine will in the common aspect of the thing willed, it is conformed thereto in the point of the last end. While, inasmuch as it is not conformed to the Divine will in the thing willed materially, it is conformed to that will considered as efficient cause; since the proper inclination consequent to nature, or to the particular apprehension of some particular thing, comes to a thing from God as its efficient cause. Hence it is customary to say that a man's will, in this respect, is conformed to the Divine will, because it wills what God wishes him to will.

There is yet another kind of conformity in respect of the formal cause, consisting in man's willing something from charity, as God wills it. And this conformity is also reduced to the formal conformity, that is in respect of the last end, which is the proper object of charity.

Reply Obj. 1: We can know in a general way what God wills. For we know that whatever God wills, He wills it under the aspect of good. Consequently whoever wills a thing under any aspect of good, has a will conformed to the Divine will, as to the reason of the thing willed. But we know not what God wills in particular: and in this respect we are not bound to conform our will to the Divine will.

But in the state of glory, every one will see in each thing that he wills, the relation of that thing to what God wills in that particular matter. Consequently he will conform his will to God in all things not only formally, but also materially.

Reply Obj. 2: God does not will the damnation of a man, considered precisely as damnation, nor a man's death, considered precisely as death, because, "He wills all men to be saved" (1 Tim. 2:4); but He wills such things under the aspect of justice. Wherefore in regard to such things it suffices for man to will the upholding of God's justice and of the natural order.

Wherefore the reply to the Third Objection is evident.

To the first argument advanced in a contrary sense, it should be said that a man who conforms his will to God's, in the aspect of reason of the thing willed, wills what God wills, more than the man, who conforms his will to God's, in the point of the very thing willed; because the will tends more to the end, than to that which is on account of the end.

To the second, it must be replied that the species and form of an act are taken from the object considered formally, rather than from the object considered materially.

To the third, it must be said that there is no opposition of wills when several people desire different things, but not under the same aspect: but there is opposition of wills, when under one and the same aspect, one man wills a thing which another wills not. But there is no question of this here.

We must next consider goodness and malice as to external actions: under which head there are six points of inquiry:

(1) Whether goodness and malice is first in the act of the will, or in the external action?

(2) Whether the whole goodness or malice of the external action depends on the goodness of the will?

(3) Whether the goodness and malice of the interior act are the same as those of the external action?

(4) Whether the external action adds any goodness or malice to that of the interior act?

(5) Whether the consequences of an external action increase its goodness or malice?

(6) Whether one and the same external action can be both good and evil? ________________________

FIRST ARTICLE [I-II, Q. 20, Art. 1]

Whether Goodness or Malice Is First in the Action of the Will, or in the External Action?

Objection 1: It would seem that good and evil are in the external action prior to being in the act of the will. For the will derives goodness from its object, as stated above (Q. 19, AA. 1, 2). But the external action is the object of the interior act of the will: for a man is said to will to commit a theft, or to will to give an alms. Therefore good and evil are in the external action, prior to being in the act of the will.

Obj. 2: Further, the aspect of good belongs first to the end: since what is directed to the end receives the aspect of good from its relation to the end. Now whereas the act of the will cannot be an end, as stated above (Q. 1, A. 1, ad 2), the act of another power can be an end. Therefore good is in the act of some other power prior to being in the act of the will.

Obj. 3: Further, the act of the will stands in a formal relation to the external action, as stated above (Q. 18, A. 6). But that which is formal is subsequent; since form is something added to matter. Therefore good and evil are in the external action, prior to being in the act of the will.

On the contrary, Augustine says (Retract. i, 9) that "it is by the will that we sin, and that we behave aright." Therefore moral good and evil are first in the will.

I answer that, External actions may be said to be good or bad in two ways. First, in regard to their genus, and the circumstances connected with them: thus the giving of alms, if the required conditions be observed, is said to be good. Secondly, a thing is said to be good or evil, from its relation to the end: thus the giving of alms for vainglory is said to be evil. Now, since the end is the will's proper object, it is evident that this aspect of good or evil, which the external action derives from its relation to the end, is to be found first of all in the act of the will, whence it passes to the external action. On the other hand, the goodness or malice which the external action has of itself, on account of its being about due matter and its being attended by due circumstances, is not derived from the will, but rather from the reason. Consequently, if we consider the goodness of the external action, in so far as it comes from reason's ordination and apprehension, it is prior to the goodness of the act of the will: but if we consider it in so far as it is in the execution of the action done, it is subsequent to the goodness of the will, which is its principle.

Reply Obj. 1: The exterior action is the object of the will, inasmuch as it is proposed to the will by the reason, as good apprehended and ordained by the reason: and thus it is prior to the good in the act of the will. But inasmuch as it is found in the execution of the action, it is an effect of the will, and is subsequent to the will.

Reply Obj. 2: The end precedes in the order of intention, but follows in the order of execution.

Reply Obj. 3: A form as received into matter, is subsequent to matter in the order of generation, although it precedes it in the order of nature: but inasmuch as it is in the active cause, it precedes in every way. Now the will is compared to the exterior action, as its efficient cause. Wherefore the goodness of the act of the will, as existing in the active cause, is the form of the exterior action. ________________________
