"Justice is peculiarly stringent. Its demands may not be modified. Judges and rulers must 'do justice though the heavens fall', not allow family connections, friendship, or even personal worth to turn them aside."

“The one thing we can say is that if Socrates really expected to get a definitive answer to his question, 'What is justice?' when talking to his friends on their way back to the Piraeus, he has been disappointed. It remains a contentious and disputed subject.”

“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?”

“Plato was accused by some of his twentieth-century critics of racism, totalitarianism, fascism, and other political crimes with a very contemporary flavor. These accusations are too anachronistic to be taken seriously; whatever explains Hitler and Mussolini, it is not the dialogues of Plato. The more plausible complaint is that Plato does not take seriously the inescapability of politics in some form. Plato’s metaphysics is fascinating; so is his conviction that the just man does better than the unjust man, no matter what earthly fate befalls him. His political thinking often amounts to an injunction to abolish the conflicts that politics exists to resolve and fantasies about how it might be done.”

“John Rawls says that justice is the 'first virtue' of social institutions, meaning that it is more fundamental than any other, and that we cannot expect individuals to accept social regulation, and engage in social co-operation unless the terms on which society operates are seen as reasonably just. To talk as though Plato and Aristotle saw justice as a matter of the terms of social and political co-operation may suggest a modern and individualist perspective foreign to both. Yet it is not wholly misleading.”

“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.”

“Political thought as we understand it began in Athens because the Athenians were a trading people who looked at their contemporaries and saw how differently they organized themselves. If they had not lived where they did and organized their economic lives as they did, they could not have seen the contrast. Given the opportunity, they might not have paid attention to it. The Israelites of the Old Testament narrative were very conscious of their neighbors, Egyptian, Babylonian, and other, not least because they were often reduced to slavery or near-slavery by them. That narrative makes nothing of the fact that Egypt was a bureaucratic theocracy; it emphasizes that the Egyptians did not worship Yahweh. The history of Old Testament politics is the history of a people who did their best to have no politics. They saw themselves as under the direct government of God, with little room to decide their own fate except by obeying or disobeying God’s commandments. Only when God took them at their word and allowed them to choose a king did they become a political society, with familiar problems of competition for office and issues of succession. For the Jews, politics was a fall from grace. For the Greeks, it was an achievement. Many besides Plato thought it a flawed achievement; when historians and philosophers began to articulate its flaws, the history of political thought began among the argumentative Athenians.”
