Republican voice of duty, eloquence, and civic virtue

Marcus Tullius Cicero was born in Arpinum and rose through talent, education, and ambition to become Rome's most famous orator and one of the leading statesmen of the late Republic. His career unfolded amid civil war, faction, and the collapse of republican norms, and he defended an ideal of law-governed public life against both demagoguery and tyranny. In his philosophical works he translated Greek ethical and political thought into a Roman civic idiom. On Duties became one of the most enduring statements of honorable conduct, public responsibility, and the relation between expediency and the right.

THESISOn Duties

Individual and Common Align

The author argues that individual and civic interests are identical, and that nature's dictate to promote human good implies common interests.

Nature's Opposition to Wrong

Cicero reiterates that immorality cannot be made right by concealment, nor can what is wrong ever become truly expedient due to the opposition of nature. This is a foundational ethical principle.

For as what is immoral, though concealed, cannot be in any way made right, so it cannot be brought about that, in spite of the opposition and repugnancy of nature, what is not right should in any case be expedient.

Virtue's Social Leverage

Cicero argues that virtue uniquely reconciles human minds and channels their goodwill, contrasting it with mechanic arts that handle inanimate objects and beasts. He asserts that only wisdom and virtue can prompt men to improve conditions through their good will.

Since, then, there is no doubt on this point, that men transcend all other causes both of benefit and of injury to men, I maintain that it is a special property of virtue to conciliate the minds of men, and to make them availing for its own uses. Thus, while...

Becomingness as Social Grace

The author argues that becomingness in life, like bodily symmetry, arises from order and moderation. A certain respect should be shown to all, as indifference to opinion is reckless, but justice and courtesy differ in treatment of men.

For as the beauty of the body attracts notice by the symmetry of the limbs, and gives delight by the very fact that all its parts harmonize with a certain graceful effect, so this becomingness which shines in the life calls forth the esteem of society by the...
