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.

Reply Obj. 2: Given that the act of the will is fixed on some good,

no circumstances can make that act bad. Consequently when it is said

that a man wills a good when he ought not, or where he ought not,

this can be understood in two ways. First, so that this circumstance

is referred to the thing willed. And thus the act of the will is not

fixed on something good: since to will to do something when it ought

not to be done, is not to will something good. Secondly, so that the

circumstance is referred to the act of willing. And thus, it is

impossible to will something good when one ought not to, because one

ought always to will what is good: except, perhaps, accidentally, in

so far as a man by willing some particular good, is prevented from

willing at the same time another good which he ought to will at that

time. And then evil results, not from his willing that particular

good, but from his not willing the other. The same applies to the

other circumstances.

Reply Obj. 3: Ignorance of circumstances excuses malice of the will,

in so far as the circumstance affects the thing willed: that is to

say, in so far as a man ignores the circumstances of the act which

he wills.
