As his life and death suggest, Cicero was addicted to Roman politics; he wrote beautifully about the… — Alan Ryan

The very idea of a Christian political theology is problematic. If human beings are only transitorily on earth, and earth is but a vale of tears through which we must pass on our way to paradise, earthly politics loses almost all value. Life in the polis cannot be the good life for man, since fulfillment lies in the hereafter; here below, we must prepare for eternity. Earthly happiness for rational persons consists in whatever confidence they may entertain about the life hereafter. This “abstentionist” vision is in some ways at odds with the involvement of Christ in the everyday life of the community in which he spent his short life.

Cicero bent Greek ideas to his vision of the idealized Roman Republic, and his understanding of the mores—the morality and social attachments—of the gentlemanly statesmen who would hold power in a just republic. Readers familiar with Machiavelli’s Prince will hear curious echoes of that work in Cicero’s advice; curious because the pieties of Cicero’s advice to the would-be statesman were satirized by Machiavelli sixteen hundred years later. If his philosophy was Greek and eclectic, Cicero owed his constitutional theory to Polybius; he was born soon after Polybius died, and read his history. And Cicero greatly admired Polybius’s friend and employer Scipio the Younger. There are obvious differences of tone. Polybius celebrated Rome’s achievement of equipoise, while Cicero lamented the ruin of the republic. Cicero’s account of republican politics veers between a “constitutional” emphasis on the way that good institutions allow a state to function by recruiting men of good but not superhuman character, and a “heroic” emphasis on the role of truly great men in reconstituting the state when it has come to ruin. Cicero’s vanity was so notorious that everyone knew he had himself in mind as this hero—had he not saved the republic before when he quelled the conspiracy of Catiline?

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.
