FIFTH ARTICLE [I-II, Q. 59, Art. 5]

Whether There Can Be Moral Virtue Without Passion?

Objection 1: It would seem that moral virtue can be without passion.

For the more perfect moral virtue is, the more does it overcome the

passions. Therefore at its highest point of perfection it is

altogether without passion.

Obj. 2: Further, then is a thing perfect, when it is removed from its

contrary and from whatever inclines to its contrary. Now the passions

incline us to sin which is contrary to virtue: hence (Rom. 7:5) they

are called "passions of sins." Therefore perfect virtue is altogether

without passion.

Obj. 3: Further, it is by virtue that we are conformed to God, as

Augustine declares (De Moribus Eccl. vi, xi, xiii). But God does all

things without passion at all. Therefore the most perfect virtue is

without any passion.

_On the contrary,_ "No man is just who rejoices not in his deeds," as

stated in _Ethic._ i, 8. But joy is a passion. Therefore justice

cannot be without passion; and still less can the other virtues be.

_I answer that,_ If we take the passions as being inordinate

emotions, as the Stoics did, it is evident that in this sense perfect

virtue is without the passions. But if by passions we understand any

movement of the sensitive appetite, it is plain that moral virtues,

which are about the passions as about their proper matter, cannot be

without passions. The reason for this is that otherwise it would

follow that moral virtue makes the sensitive appetite altogether

idle: whereas it is not the function of virtue to deprive the powers

subordinate to reason of their proper activities, but to make them

execute the commands of reason, by exercising their proper acts.

Wherefore just as virtue directs the bodily limbs to their due

external acts, so does it direct the sensitive appetite to its proper

regulated movements.

Those moral virtues, however, which are not about the passions, but

about operations, can be without passions. Such a virtue is justice:

because it applies the will to its proper act, which is not a

passion. Nevertheless, joy results from the act of justice; at least

in the will, in which case it is not a passion. And if this joy be

increased through the perfection of justice, it will overflow into

the sensitive appetite; in so far as the lower powers follow the

movement of the higher, as stated above (Q. 17, A. 7; Q. 24, A. 3).

Wherefore by reason of this kind of overflow, the more perfect a

virtue is, the more does it cause passion.

Reply Obj. 1: Virtue overcomes inordinate passion; it produces

ordinate passion.

Reply Obj. 2: It is inordinate, not ordinate, passion that leads to

sin.

Reply Obj. 3: The good of anything depends on the condition of its

nature. Now there is no sensitive appetite in God and the angels, as

there is in man. Consequently good operation in God and the angels is

altogether without passion, as it is without a body: whereas the good

operation of man is with passion, even as it is produced with the

body's help.
