THIRD ARTICLE [I-II, Q. 16, Art. 3]

Whether Use Regards Also the Last End?

Objection 1: It would seem that use can regard also the last end. For

Augustine says (De Trin. x, 11): "Whoever enjoys, uses." But man

enjoys the last end. Therefore he uses the last end.

Obj. 2: Further, "to use is to apply something to the purpose of the

will" (De Trin. x, 11). But the last end, more than anything else, is

the object of the will's application. Therefore it can be the object

of use.

Obj. 3: Further, Hilary says (De Trin. ii) that "Eternity is in the

Father, Likeness in the Image," i.e. in the Son, "Use in the Gift,"

i.e. in the Holy Ghost. But the Holy Ghost, since He is God, is the

last end. Therefore the last end can be the object of use.

_On the contrary,_ Augustine says (QQ. 83, qu. 30): "No one rightly

uses God, but one enjoys Him." But God alone is the last end.

Therefore we cannot use the last end.

_I answer that,_ Use, as stated above (A. 1), implies the application

of one thing to another. Now that which is applied to another is

regarded in the light of means to an end; and consequently use always

regards the means. For this reason things that are adapted to a

certain end are said to be "useful"; in fact their very usefulness is

sometimes called use.

It must, however, be observed that the last end may be taken in two

ways: first, simply; secondly, in respect of an individual. For

since the end, as stated above (Q. 1, A. 8; Q. 2, A. 7), signifies

sometimes the thing itself, and sometimes the attainment or

possession of that thing (thus the miser's end is either money or

the possession of it); it is evident that, simply speaking, the last

end is the thing itself; for the possession of money is good only

inasmuch as there is some good in money. But in regard to the

individual, the obtaining of money is the last end; for the miser

would not seek for money, save that he might have it. Therefore,

simply and properly speaking, a man enjoys money, because he places

his last end therein; but in so far as he seeks to possess it, he

is said to use it.

Reply Obj. 1: Augustine is speaking of use in general, in so far as

it implies the relation of an end to the enjoyment which a man seeks

in that end.

Reply Obj. 2: The end is applied to the purpose of the will, that

the will may find rest in it. Consequently this rest in the end,

which is the enjoyment thereof, is in this sense called use of the

end. But the means are applied to the will's purpose, not only in

being used as means, but as ordained to something else in which the

will finds rest.

Reply Obj. 3: The words of Hilary refer to use as applicable

to rest in the last end; just as, speaking in a general sense, one may

be said to use the end for the purpose of attaining it, as stated

above. Hence Augustine says (De Trin. vi, 10) that "this love, delight,

felicity, or happiness, is called use by him."
