Q: Whether the Other Six Precepts of the Decalogue Are Fittingly Expressed?

A: On the contrary,
stands the authority of Scripture.

I answer that,
Just as by the parts of justice a man pays that which is due to certain definite persons, to whom he is bound for some special reason, so too by justice properly so called he pays that which is due to all in general. Hence, after the three precepts pertaining to religion, whereby man pays what is due God, and after the fourth precept pertaining to piety, whereby he pays what is due to his parents--which duty includes the paying of all that is due for any special reason--it was necessary in due sequence to give certain precepts pertaining to justice properly so called, which pays to all indifferently what is due to them.

Reply Obj. 1: Man is bound towards all persons in general to inflict injury on no one: hence the negative precepts, which forbid the doing of those injuries that can be inflicted on one's neighbor, had to be given a place, as general precepts, among the precepts of the decalogue. On the other hand, the duties we owe to our neighbor are paid in different ways to different people: hence it did not behoove to include affirmative precepts about those duties among the precepts of the decalogue.

Reply Obj. 2: All other injuries that are inflicted on our neighbor are reducible to those that are forbidden by these precepts, as taking precedence of others in point of generality and importance. For all injuries that are inflicted on the person of our neighbor are understood to be forbidden under the head of murder as being the principal of all. Those that are inflicted on a person connected with one's neighbor, especially by way of lust, are understood to be forbidden together with adultery: those that come under the head of damage done to property are understood to be forbidden together with theft: and those that are comprised under speech, such as detractions, insults, and so forth, are understood to be forbidden together with the bearing of false witness, which is more directly opposed to justice.

Reply Obj. 3: The precepts forbidding concupiscence do not include the prohibition of first movements of concupiscence, that do not go farther than the bounds of sensuality. The direct object of their prohibition is the consent of the will, which is directed to deed or pleasure.

Reply Obj. 4: Murder in itself is an object not of concupiscence but of horror, since it has not in itself the aspect of good. On the other hand, adultery has the aspect of a certain kind of good, i.e. of something pleasurable, and theft has an aspect of good, i.e. of something useful: and good of its very nature has the aspect of something concupiscible. Hence the concupiscence of theft and adultery had to be forbidden by special precepts, but not the concupiscence of murder.

TREATISE ON FORTITUDE AND TEMPERANCE (QQ. 123-170)

QUESTION 123

OF FORTITUDE (In Twelve Articles)

After considering justice we must in due sequence consider fortitude. We must (1) consider the virtue itself of fortitude; (2) its parts; (3) the gift corresponding thereto; (4) the precepts that pertain to it.

Concerning fortitude three things have to be considered: (1) Fortitude itself; (2) its principal act, viz. martyrdom; (3) the vices opposed to fortitude.

Under the first head there are twelve points of inquiry:

(1) Whether fortitude is a virtue?

(2) Whether it is a special virtue?

(3) Whether fortitude is only about fear and daring?

(4) Whether it is only about fear of death?

(5) Whether it is only in warlike matters?

(6) Whether endurance is its chief act?

(7) Whether its action is directed to its own good?

(8) Whether it takes pleasure in its own action?

(9) Whether fortitude deals chiefly with sudden occurrences?

(10) Whether it makes use of anger in its action?

(11) Whether it is a cardinal virtue?

(12) Of its comparison with the other cardinal virtues.
