FIRST ARTICLE [I-II, Q. 26, Art. 1]

Whether Love Is in the Concupiscible Power?

Objection 1: It would seem that love is not in the concupiscible

power. For it is written (Wis. 8:2): "Her," namely wisdom, "have I

loved, and have sought her out from my youth." But the concupiscible

power, being a part of the sensitive appetite, cannot tend to wisdom,

which is not apprehended by the senses. Therefore love is not in the

concupiscible power.

Obj. 2: Further, love seems to be identified with every passion: for

Augustine says (De Civ. Dei xiv, 7): "Love, yearning for the object

beloved, is desire; having and enjoying it, is joy; fleeing what is

contrary to it, is fear; and feeling what is contrary to it, is

sadness." But not every passion is in the concupiscible power;

indeed, fear, which is mentioned in this passage, is in the irascible

power. Therefore we must not say absolutely that love is in the

concupiscible power.

Obj. 3: Further, Dionysius (Div. Nom. iv) mentions a "natural love."

But natural love seems to pertain rather to the natural powers, which

belong to the vegetal soul. Therefore love is not simply in the

concupiscible power.

_On the contrary,_ The Philosopher says (Topic. ii, 7) that "love is

in the concupiscible power."

_I answer that,_ Love is something pertaining to the appetite; since

good is the object of both. Wherefore love differs according to the

difference of appetites. For there is an appetite which arises from

an apprehension existing, not in the subject of the appetite, but in

some other: and this is called the _natural appetite._ Because

natural things seek what is suitable to them according to their

nature, by reason of an apprehension which is not in them, but in the

Author of their nature, as stated in the First Part (Q. 6, A. 1, ad

2; Q. 103, A. 1, ad 1, 3). And there is another appetite arising from

an apprehension in the subject of the appetite, but from necessity

and not from free-will. Such is, in irrational animals, the

_sensitive appetite,_ which, however, in man, has a certain share of

liberty, in so far as it obeys reason. Again, there is another

appetite following freely from an apprehension in the subject of the

appetite. And this is the rational or intellectual appetite, which is

called the _will._

Now in each of these appetites, the name "love" is given to the

principle of movement towards the end loved. In the natural appetite

the principle of this movement is the appetitive subject's

connaturalness with the thing to which it tends, and may be called

"natural love": thus the connaturalness of a heavy body for the

centre, is by reason of its weight and may be called "natural love."

In like manner the aptitude of the sensitive appetite or of the will

to some good, that is to say, its very complacency in good is called

"sensitive love," or "intellectual" or "rational love." So that

sensitive love is in the sensitive appetite, just as intellectual

love is in the intellectual appetite. And it belongs to the

concupiscible power, because it regards good absolutely, and not

under the aspect of difficulty, which is the object of the irascible

faculty.

Reply Obj. 1: The words quoted refer to intellectual or rational love.

Reply Obj. 2: Love is spoken of as being fear, joy, desire and

sadness, not essentially but causally.

Reply Obj. 3: Natural love is not only in the powers of the

vegetal soul, but in all the soul's powers, and also in all the parts

of the body, and universally in all things: because, as Dionysius says

(Div. Nom. iv), "Beauty and goodness are beloved by all things"; since

each single thing has a connaturalness with that which is naturally

suitable to it.
