FIFTH ARTICLE [I-II, Q. 32, Art. 5]

Whether the Actions of Others Are a Cause of Pleasure to Us?

Objection 1: It would seem that the actions of others are not a cause

of pleasure to us. Because the cause of pleasure is our own good when

conjoined to us. But the actions of others are not conjoined to us.

Therefore they are not a cause of pleasure to us.

Obj. 2: Further, the action is the agent's own good. If, therefore,

the actions of others are a cause of pleasure to us, for the same

reason all goods belonging to others will be pleasing to us: which is

evidently untrue.

Obj. 3: Further, action is pleasant through proceeding from an innate

habit; hence it is stated in _Ethic._ ii, 3 that "we must reckon the

pleasure which follows after action, as being the sign of a habit

existing in us." But the actions of others do not proceed from habits

existing in us, but, sometimes, from habits existing in the agents.

Therefore the actions of others are not pleasing to us, but to the

agents themselves.

_On the contrary,_ It is written in the second canonical epistle of

John (verse 4): "I was exceeding glad that I found thy children

walking in truth."

_I answer that,_ As stated above (A. 1; Q. 31, A. 1), two things are

requisite for pleasure, namely, the attainment of one's proper good,

and the knowledge of having obtained it. Wherefore the action of

another may cause pleasure to us in three ways. First, from the fact

that we obtain some good through the action of another. And in this

way, the actions of those who do some good to us, are pleasing to us:

since it is pleasant to be benefited by another. Secondly, from the

fact that another's action makes us to know or appreciate our own

good: and for this reason men take pleasure in being praised or

honored by others, because, to wit, they thus become aware of some

good existing in themselves. And since this appreciation receives

greater weight from the testimony of good and wise men, hence men

take greater pleasure in being praised and honored by them. And

because a flatterer appears to praise, therefore flattery is pleasing

to some. And as love is for something good, while admiration is for

something great, so it is pleasant to be loved and admired by others,

inasmuch as a man thus becomes aware of his own goodness or

greatness, through their giving pleasure to others. Thirdly, from the

fact that another's actions, if they be good, are reckoned as one's

own good, by reason of the power of love, which makes a man to regard

his friend as one with himself. And on account of hatred, which makes

one to reckon another's good as being in opposition to oneself, the

evil action of an enemy becomes an object of pleasure: whence it is

written (1 Cor. 13:6) that charity "rejoiceth not in iniquity, but

rejoiceth with the truth."

Reply Obj. 1: Another's action may be conjoined to me, either by its

effect, as in the first way, or by knowledge, as in the second way;

or by affection, as in the third way.

Reply Obj. 2: This argument avails for the third mode, but not for

the first two.

Reply Obj. 3: Although the actions of another do not proceed from

habits that are in me, yet they either produce in me something that

gives pleasure; or they make me appreciate or know a habit of mind;

or they proceed from the habit of one who is united to me by love.
