FIRST ARTICLE [II-II, Q. 79, Art. 1]

Whether to Decline from Evil and to Do Good Are Parts of Justice?

Objection 1: It would seem that to decline from evil and to do good

are not parts of justice. For it belongs to every virtue to perform a

good deed and to avoid an evil one. But parts do not exceed the

whole. Therefore to decline from evil and to do good should not be

reckoned parts of justice, which is a special kind of virtue.

Obj. 2: Further, a gloss on Ps. 33:15, "Turn away from evil and do

good," says: "The former," i.e. to turn away from evil, "avoids sin,

the latter," i.e. to do good, "deserves the life and the palm." But

any part of a virtue deserves the life and the palm. Therefore to

decline from evil is not a part of justice.

Obj. 3: Further, things that are so related that one implies the

other, are not mutually distinct as parts of a whole. Now declining

from evil is implied in doing good: since no one does evil and good

at the same time. Therefore declining from evil and doing good are

not parts of justice.

_On the contrary,_ Augustine (De Correp. et Grat. i) declares that

"declining from evil and doing good" belong to the justice of the law.

_I answer that,_ If we speak of good and evil in general, it belongs

to every virtue to do good and to avoid evil: and in this sense they

cannot be reckoned parts of justice, except justice be taken in the

sense of "all virtue" [*Cf. Q. 58, A. 5]. And yet even if justice be

taken in this sense it regards a certain special aspect of good;

namely, the good as due in respect of Divine or human law.

On the other hand justice considered as a special virtue regards good

as due to one's neighbor. And in this sense it belongs to special

justice to do good considered as due to one's neighbor, and to avoid

the opposite evil, that, namely, which is hurtful to one's neighbor;

while it belongs to general justice to do good in relation to the

community or in relation to God, and to avoid the opposite evil.

Now these two are said to be quasi-integral parts of general or of

special justice, because each is required for the perfect act of

justice. For it belongs to justice to establish equality in our

relations with others, as shown above (Q. 58, A. 2): and it pertains

to the same cause to establish and to preserve that which it has

established. Now a person establishes the equality of justice by

doing good, i.e. by rendering to another his due: and he preserves

the already established equality of justice by declining from evil,

that is by inflicting no injury on his neighbor.

Reply Obj. 1: Good and evil are here considered under a special

aspect, by which they are appropriated to justice. The reason why

these two are reckoned parts of justice under a special aspect of

good and evil, while they are not reckoned parts of any other moral

virtue, is that the other moral virtues are concerned with the

passions wherein to do good is to observe the mean, which is the same

as to avoid the extremes as evils: so that doing good and avoiding

evil come to the same, with regard to the other virtues. On the other

hand justice is concerned with operations and external things,

wherein to establish equality is one thing, and not to disturb the

equality established is another.

Reply Obj. 2: To decline from evil, considered as a part of justice,

does not denote a pure negation, viz. "not to do evil"; for this does

not deserve the palm, but only avoids the punishment. But it implies

a movement of the will in repudiating evil, as the very term

"decline" shows. This is meritorious; especially when a person

resists against an instigation to do evil.

Reply Obj. 3: Doing good is the completive act of justice, and the

principal part, so to speak, thereof. Declining from evil is a more

imperfect act, and a secondary part of that virtue. Hence it is a

material part, so to speak, thereof, and a necessary condition of the

formal and completive part.
