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

Reply Obj. 1: In things which can be more or less intense, the difference of more or less does not change the species: thus by differing in whiteness through being more or less white a thing is not changed in regard to its species of color. In like manner that which makes an action to be more or less good or evil, does not make the action differ in species.

Reply Obj. 2: A circumstance that aggravates a sin, or adds to the goodness of an action, sometimes has no goodness or malice in itself, but in regard to some other condition of the action, as stated above. Consequently it does not add a new species, but adds to the goodness or malice derived from this other condition of the action.

Reply Obj. 3: A circumstance does not always involve a distinct defect of its own; sometimes it causes a defect in reference to something else. In like manner a circumstance does not always add further perfection, except in reference to something else. And, for as much as it does, although it may add to the goodness or malice, it does not always change the species of good or evil.

We must now consider the goodness of the interior act of the will; under which head there are ten points of inquiry:

(1) Whether the goodness of the will depends on the object?

(2) Whether it depends on the object alone?

(3) Whether it depends on reason?

(4) Whether it depends on the eternal law?

(5) Whether erring reason binds?

(6) Whether the will is evil if it follows the erring reason against the law of God?

(7) Whether the goodness of the will in regard to the means, depends on the intention of the end?

(8) Whether the degree of goodness or malice in the will depends on the degree of good or evil in the intention?

(9) Whether the goodness of the will depends on its conformity to the Divine Will?

(10) Whether it is necessary for the human will, in order to be good, to be conformed to the Divine Will, as regards the thing willed? ________________________

FIRST ARTICLE [I-II, Q. 19, Art. 1]

Whether the Goodness of the Will Depends on the Object?

Objection 1: It would seem that the goodness of the will does not depend on the object. For the will cannot be directed otherwise than to what is good: since "evil is outside the scope of the will," as Dionysius says (Div. Nom. iv). If therefore the goodness of the will depended on the object, it would follow that every act of the will is good, and none bad.

Obj. 2: Further, good is first of all in the end: wherefore the goodness of the end, as such, does not depend on any other. But, according to the Philosopher (Ethic. vi, 5), "goodness of action is the end, but goodness of making is never the end": because the latter is always ordained to the thing made, as to its end. Therefore the goodness of the act of the will does not depend on any object.

Obj. 3: Further, such as a thing is, such does it make a thing to be. But the object of the will is good, by reason of the goodness of nature. Therefore it cannot give moral goodness to the will. Therefore the moral goodness of the will does not depend on the object.

On the contrary, the Philosopher says (Ethic. v, 1) that justice is that habit "from which men wish for just things": and accordingly, virtue is a habit from which men wish for good things. But a good will is one which is in accordance with virtue. Therefore the goodness of the will is from the fact that a man wills that which is good.

I answer that, Good and evil are essential differences of the act of the will. Because good and evil of themselves regard the will; just as truth and falsehood regard reason; the act of which is divided essentially by the difference of truth and falsehood, for as much as an opinion is said to be true or false. Consequently good and evil will are acts differing in species. Now the specific difference in acts is according to objects, as stated above (Q. 18, A. 5). Therefore good and evil in the acts of the will is derived properly from the objects.

Reply Obj. 1: The will is not always directed to what is truly good, but sometimes to the apparent good; which has indeed some measure of good, but not of a good that is simply suitable to be desired. Hence it is that the act of the will is not always good, but sometimes evil.

Reply Obj. 2: Although an action can, in a certain way, be man's last end; nevertheless such action is not an act of the will, as stated above (Q. 1, A. 1, ad 2).

Reply Obj. 3: Good is presented to the will as its object by the reason: and in so far as it is in accord with reason, it enters the moral order, and causes moral goodness in the act of the will: because the reason is the principle of human and moral acts, as stated above (Q. 18, A. 5). ________________________

SECOND ARTICLE [I-II, Q. 19, Art. 2]

Whether the goodness of the will depends on the object alone?

Objection 1: It would seem that the goodness of the will does not depend on the object alone. For the end has a closer relationship to the will than to any other power. But the acts of the other powers derive goodness not only from the object but also from the end, as we have shown above (Q. 18, A. 4). Therefore the act also of the will derives goodness not only from the object but also from the end.

Obj. 2: Further, the goodness of an action is derived not only from the object but also from the circumstances, as stated above (Q. 18, A. 3). But according to the diversity of circumstances there may be diversity of goodness and malice in the act of the will: for instance, if a man will, when he ought, where he ought, as much as he ought, and how he ought, or if he will as he ought not. Therefore the goodness of the will depends not only on the object, but also on the circumstances.

Obj. 3: Further, ignorance of circumstances excuses malice of the will, as stated above (Q. 6, A. 8). But it would not be so, unless the goodness or malice of the will depended on the circumstances. Therefore the goodness and malice of the will depend on the circumstances, and not only on the object.

On the contrary, An action does not take its species from the circumstances as such, as stated above (Q. 18, A. 10, ad 2). But good and evil are specific differences of the act of the will, as stated above (A. 1). Therefore the goodness and malice of the will depend, not on the circumstances, but on the object alone.

I answer that, In every genus, the more a thing is first, the more simple it is, and the fewer the principles of which it consists: thus primary bodies are simple. Hence it is to be observed that the first things in every genus, are, in some way, simple and consist of one principle. Now the principle of the goodness and malice of human actions is taken from the act of the will. Consequently the goodness and malice of the act of the will depend on some one thing; while the goodness and malice of other acts may depend on several things.

Now that one thing which is the principle in each genus, is not something accidental to that genus, but something essential thereto: because whatever is accidental is reduced to something essential, as to its principle. Therefore the goodness of the will's act depends on that one thing alone, which of itself causes goodness in the act; and that one thing is the object, and not the circumstances, which are accidents, as it were, of the act.

Reply Obj. 1: The end is the object of the will, but not of the other powers. Hence, in regard to the act of the will, the goodness derived from the object, does not differ from that which is derived from the end, as they differ in the acts of the other powers; except perhaps accidentally, in so far as one end depends on another, and one act of the will on another.
