Together with the histories of Polybius and Livy, Cicero’s polemical speeches and writings, and his personal correspondence, form some of the most im… - Alan Ryan

Justice is closely connected to respect for rights. Modern writers discuss both subjects together with no suggestion that one might discuss one with the other. It was not always so. Greek political theory and Roman Law had sophisticated ideas about justice in its various aspects, but did not embrace our conception of individual rights. This may seem counter-intuitive. How could a society recognize someone as the owner of a piece of property without acknowledging an individual right? How does legitimate one-man­ rule, monarchy, differ from its illegitimate parody, tyranny, unless the lawful king has a right to the authority he exercises that the tyrant does not?
The answer is that property and authority were defined by law rather than our notion of individual rights. To own property was to be the person to whom the law accorded the privileges and immunities that locally defined ownership. To be a legitimate ruler was to be the person the law designated to rule. It is a commonplace that ancient notions of law accorded far more power over property to the family and other groups than modern notions of private property do. Even under the Roman Law, where ownership had an 'absolute' and sovereign character, property was not understood in the modern way; when the law told the judge to give a man his ius, this primarily meant that he should be treated as the law required. The 'subjective' understanding of rights, whereby the right-holder may stand on his rights or not as he chooses, was not a Roman notion.

I am uncomfortable with the thought that serious thinkers about politics may retire into the ivory tower and write difficult—if often very interesting—essays and books for their colleagues alone, leaving debates over the prospects of modern political life to the punditry of contributors to the op-ed pages, or the shouting matches that pass for political debate on some television channels.

Cicero’s style is a key to the success of De officiis, and not just the literary style, but the political and intellectual style. Regulus aside, the demands of duty generally stretch only as far as the well-educated, well-to-do man is likely to follow. Thus, he insists, in a famous metaphor that Machiavelli later stood on its head, that courage is necessary but the courage of a human being is not the ferocity of the lion, just as wisdom is necessary but the intelligence of the human being is not the cunning of the fox.
