“The point of civilization is to be civilized; the purpose of action is to perpetuate society, for only in society can philosophy truly take place.”

“Odd, don't you think? I have seen war, and invasions and riots. I have heard of massacres and brutalities beyond imagining, and I have kept my faith in the power of civilization to bring men back from the brink. And yet one women writes a letter, and my whole world falls to pieces.You see, she is an ordinary woman. A good one, even. That's the point ... Nothing [a recognizably bad person does] can surprise or shock me, or worry me. But she denounced Julia and sent her to her death because she resented her, and because Julia is a Jew.I thought in this simple contrast between the civilized and the barbaric, but I was wrong. It is the civilized who are the truly barbaric, and the [Nazi] Germans are merely the supreme expression of it.”

“Action is the activity of the rational soul, which abhors irrationality and must combat it or be corrupted by it. When it sees the irrationality of others, it must seek to correct it, and can do this either by teaching or engaging in public affairs itself, correcting through its practice. And the purpose of action is to enable philosophy to continue, for if men are reduced to the material alone, they become no more than beasts.”

“And here was the moment. The end of it all, for civilization was merely another name for friendship, and friendship was coming to an end.”

“Civilization depends on continually making the effort, of never giving in. It needs to be cared for by men of goodwill, protected from the dark.”

“Manlius ... took care in his invitations, actively sought to exclude from his circle crude and vulgar men like Caius Valerius. But they were all around; it was Manlius who lived in a dream world, and his bubble of civility was becoming smaller and smaller. Caius Valerius, powerful member of a powerful family, had never even heard of Plato. A hundred, even fifty years before, such an absurdity would have been inconceivable. Now it was surprising if such a man did know anything of philosophy, and even if it was explained, he would not wish to understand.”

“Politics bores you?" Bronsen said.Julien smiled. "It does. Apologies, sir, and it is not that I haven't tried to be fascinated. But careful and meticulous research has suggested the hypothesis that all politicians are liars, fools, and tricksters, and I have as yet come across no evidence to the contrary. They can do great damage, and rarely any good. It is the job of the sensible man to try and protect civilization from their depradations.”
