Reply Obj. 1: Audacity seems to refer to the assailing of others. Consequently it belongs to those sins chiefly whereby one's neighbor is injured: and these sins are forbidden by human law, as stated.
Reply Obj. 2: The purpose of human law is to lead men to virtue, not suddenly, but gradually. Wherefore it does not lay upon the multitude of imperfect men the burdens of those who are already virtuous, viz. that they should abstain from all evil. Otherwise these imperfect ones, being unable to bear such precepts, would break out into yet greater evils: thus it is written (Ps. 30:33): "He that violently bloweth his nose, bringeth out blood"; and (Matt. 9:17) that if "new wine," i.e. precepts of a perfect life, "is put into old bottles," i.e. into imperfect men, "the bottles break, and the wine runneth out," i.e. the precepts are despised, and those men, from contempt, break into evils worse still.
Reply Obj. 3: The natural law is a participation in us of the eternal law: while human law falls short of the eternal law. Now Augustine says (De Lib. Arb. i, 5): "The law which is framed for the government of states, allows and leaves unpunished many things that are punished by Divine providence. Nor, if this law does not attempt to do everything, is this a reason why it should be blamed for what it does." Wherefore, too, human law does not prohibit everything that is forbidden by the natural law. ________________________
THIRD ARTICLE [I-II, Q. 96, Art. 3]
Whether Human Law Prescribes Acts of All the Virtues?
Objection 1: It would seem that human law does not prescribe acts of all the virtues. For vicious acts are contrary to acts of virtue. But human law does not prohibit all vices, as stated above (A. 2). Therefore neither does it prescribe all acts of virtue.
Obj. 2: Further, a virtuous act proceeds from a virtue. But virtue is the end of law; so that whatever is from a virtue, cannot come under a precept of law. Therefore human law does not prescribe all acts of virtue.
Obj. 3: Further, law is ordained to the common good, as stated above (Q. 90, A. 2). But some acts of virtue are ordained, not to the common good, but to private good. Therefore the law does not prescribe all acts of virtue.
On the contrary, The Philosopher says (Ethic. v, 1) that the law "prescribes the performance of the acts of a brave man . . . and the acts of the temperate man . . . and the acts of the meek man: and in like manner as regards the other virtues and vices, prescribing the former, forbidding the latter."
I answer that, The species of virtues are distinguished by their objects, as explained above (Q. 54, A. 2; Q. 60, A. 1; Q. 62, A. 2). Now all the objects of virtues can be referred either to the private good of an individual, or to the common good of the multitude: thus matters of fortitude may be achieved either for the safety of the state, or for upholding the rights of a friend, and in like manner with the other virtues. But law, as stated above (Q. 90, A. 2) is ordained to the common good. Wherefore there is no virtue whose acts cannot be prescribed by the law. Nevertheless human law does not prescribe concerning all the acts of every virtue: but only in regard to those that are ordainable to the common good—either immediately, as when certain things are done directly for the common good—or mediately, as when a lawgiver prescribes certain things pertaining to good order, whereby the citizens are directed in the upholding of the common good of justice and peace.
