SECOND ARTICLE [I-II, Q. 25, Art. 2]

Whether Love Is the First of the Concupiscible Passions?

Objection 1: It would seem that love is not the first of the

concupiscible passions. For the concupiscible faculty is so called

from concupiscence, which is the same passion as desire. But "things

are named from their chief characteristic" (De Anima ii, 4).

Therefore desire takes precedence of love.

Obj. 2: Further, love implies a certain union; since it is a "uniting

and binding force," as Dionysius says (Div. Nom. iv). But

concupiscence or desire is a movement towards union with the thing

coveted or desired. Therefore desire precedes love.

Obj. 3: Further, the cause precedes its effect. But pleasure is

sometimes the cause of love: since some love on account of pleasure

(Ethic. viii, 3, 4). Therefore pleasure precedes love; and

consequently love is not the first of the concupiscible passions.

_On the contrary,_ Augustine says (De Civ. Dei xiv, 7, 9) that all

the passions are caused by love: since "love yearning for the beloved

object, is desire; and, having and enjoying it, is joy." Therefore

love is the first of the concupiscible passions.

_I answer that,_ Good and evil are the object of the concupiscible

faculty. Now good naturally precedes evil; since evil is privation of

good. Wherefore all the passions, the object of which is good, are

naturally before those, the object of which is evil--that is to say,

each precedes its contrary passion: because the quest of a good is

the reason for shunning the opposite evil.

Now good has the aspect of an end, and the end is indeed first in the

order of intention, but last in the order of execution. Consequently

the order of the concupiscible passions can be considered either in

the order of intention or in the order of execution. In the order of

execution, the first place belongs to that which takes place first in

the thing that tends to the end. Now it is evident that whatever

tends to an end, has, in the first place, an aptitude or proportion

to that end, for nothing tends to a disproportionate end; secondly,

it is moved to that end; thirdly, it rests in the end, after having

attained it. And this very aptitude or proportion of the appetite to

good is love, which is complacency in good; while movement towards

good is desire or concupiscence; and rest in good is joy or pleasure.

Accordingly in this order, love precedes desire, and desire precedes

pleasure. But in the order of intention, it is the reverse: because

the pleasure intended causes desire and love. For pleasure is the

enjoyment of the good, which enjoyment is, in a way, the end, just as

the good itself is, as stated above (Q. 11, A. 3, ad 3).

Reply Obj. 1: We name a thing as we understand it, for "words are

signs of thoughts," as the Philosopher states (Peri Herm. i, 1). Now

in most cases we know a cause by its effect. But the effect of love,

when the beloved object is possessed, is pleasure: when it is not

possessed, it is desire or concupiscence: and, as Augustine says (De

Trin. x, 12), "we are more sensible to love, when we lack that which

we love." Consequently of all the concupiscible passions,

concupiscence is felt most; and for this reason the power is named

after it.

Reply Obj. 2: The union of lover and beloved is twofold. There is

real union, consisting in the conjunction of one with the other. This

union belongs to joy or pleasure, which follows desire. There is also

an affective union, consisting in an aptitude or proportion, in so

far as one thing, from the very fact of its having an aptitude for

and an inclination to another, partakes of it: and love betokens such

a union. This union precedes the movement of desire.

Reply Obj. 3: Pleasure causes love, in so far as it precedes love in

the order of intention.
