FOURTH ARTICLE [I-II, Q. 26, Art. 4]

Whether Love Is Properly Divided into Love of Friendship and Love of

Concupiscence?

Objection 1: It would seem that love is not properly divided into

love of friendship and love of concupiscence. For "love is a passion,

while friendship is a habit," according to the Philosopher (Ethic.

viii, 5). But habit cannot be the member of a division of passions.

Therefore love is not properly divided into love of concupiscence and

love of friendship.

Obj. 2: Further, a thing cannot be divided by another member of the

same division; for man is not a member of the same division as

"animal." But concupiscence is a member of the same division as love,

as a passion distinct from love. Therefore concupiscence is not a

division of love.

Obj. 3: Further, according to the Philosopher (Ethic. viii, 3)

friendship is threefold, that which is founded on _usefulness,_ that

which is founded on _pleasure,_ and that which is founded on

_goodness._ But useful and pleasant friendship are not without

concupiscence. Therefore concupiscence should not be contrasted with

friendship.

_On the contrary,_ We are said to love certain things, because we

desire them: thus "a man is said to love wine, on account of its

sweetness which he desires"; as stated in _Topic._ ii, 3. But we have

no friendship for wine and suchlike things, as stated in _Ethic._

viii, 2. Therefore love of concupiscence is distinct from love of

friendship.

_I answer that,_ As the Philosopher says (Rhet. ii, 4), "to love is

to wish good to someone." Hence the movement of love has a twofold

tendency: towards the good which a man wishes to someone (to himself

or to another) and towards that to which he wishes some good.

Accordingly, man has love of concupiscence towards the good that he

wishes to another, and love of friendship towards him to whom he

wishes good.

Now the members of this division are related as primary and

secondary: since that which is loved with the love of friendship is

loved simply and for itself; whereas that which is loved with the

love of concupiscence, is loved, not simply and for itself, but for

something else. For just as that which has existence, is a being

simply, while that which exists in another is a relative being; so,

because good is convertible with being, the good, which itself has

goodness, is good simply; but that which is another's good, is a

relative good. Consequently the love with which a thing is loved,

that it may have some good, is love simply; while the love, with

which a thing is loved, that it may be another's good, is relative

love.

Reply Obj. 1: Love is not divided into friendship and concupiscence,

but into love of friendship, and love of concupiscence. For a friend

is, properly speaking, one to whom we wish good: while we are said to

desire, what we wish for ourselves.

Hence the Reply to the Second Objection.

Reply Obj. 3: When friendship is based on usefulness or pleasure, a

man does indeed wish his friend some good: and in this respect the

character of friendship is preserved. But since he refers this good

further to his own pleasure or use, the result is that friendship of

the useful or pleasant, in so far as it is connected with love of

concupiscence, loses the character to true friendship.
