FIRST ARTICLE [I-II, Q. 8, Art. 1]

Whether the Will Is of Good Only?

Objection 1: It would seem that the will is not of good only. For the

same power regards opposites; for instance, sight regards white and

black. But good and evil are opposites. Therefore the will is not only

of good, but also of evil.

Obj. 2: Further, rational powers can be directed to opposite

purposes, according to the Philosopher (Metaph. ix, 2). But the will

is a rational power, since it is "in the reason," as is stated in _De

Anima_ iii, 9. Therefore the will can be directed to opposites; and

consequently its volition is not confined to good, but extends to

evil.

Obj. 3: Further, good and being are convertible. But volition is

directed not only to beings, but also to non-beings. For sometimes we

wish "not to walk," or "not to speak"; and again at times we wish for

future things, which are not actual beings. Therefore the will is not

of good only.

_On the contrary,_ Dionysius says (Div. Nom. iv) that "evil is

outside the scope of the will," and that "all things desire good."

_I answer that,_ The will is a rational appetite. Now every appetite

is only of something good. The reason of this is that the appetite is

nothing else than an inclination of a person desirous of a thing

towards that thing. Now every inclination is to something like and

suitable to the thing inclined. Since, therefore, everything,

inasmuch as it is being and substance, is a good, it must needs be

that every inclination is to something good. And hence it is that the

Philosopher says (Ethic. i, 1) that "the good is that which all

desire."

But it must be noted that, since every inclination results from a

form, the natural appetite results from a form existing in the nature

of things: while the sensitive appetite, as also the intellective or

rational appetite, which we call the will, follows from an

apprehended form. Therefore, just as the natural appetite tends to

good existing in a thing; so the animal or voluntary appetite tends

to a good which is apprehended. Consequently, in order that the will

tend to anything, it is requisite, not that this be good in very

truth, but that it be apprehended as good. Wherefore the Philosopher

says (Phys. ii, 3) that "the end is a good, or an apparent good."

Reply Obj. 1: The same power regards opposites, but it is not

referred to them in the same way. Accordingly, the will is referred

both to good and evil: but to good by desiring it: to evil, by

shunning it. Wherefore the actual desire of good is called "volition"

[*In Latin, 'voluntas'. To avoid confusion with "voluntas" (the will)

St. Thomas adds a word of explanation, which in the translation may

appear superfluous.], meaning thereby the act of the will; for it is

in this sense that we are now speaking of the will. On the other

hand, the shunning of evil is better described as "nolition":

wherefore, just as volition is of good, so nolition is of evil.

Reply Obj. 2: A rational power is not to be directed to all opposite

purposes, but to those which are contained under its proper object;

for no power seeks other than its proper object. Now, the object of

the will is good. Wherefore the will can be directed to such opposite

purposes as are contained under good, such as to be moved or to be at

rest, to speak or to be silent, and such like: for the will can be

directed to either under the aspect of good.

Reply Obj. 3: That which is not a being in nature, is considered as a

being in the reason, wherefore negations and privations are said to

be "beings of reason." In this way, too, future things, in so far as

they are apprehended, are beings. Accordingly, in so far as such like

are beings, they are apprehended under the aspect of good; and it is

thus that the will is directed to them. Wherefore the Philosopher

says (Ethic. v, 1) that "to lack evil is considered as a good."
