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.
[T]he concern of man is not his future but his present, not the world but his soul. We must be just, we must strive, we must engage ourselves with the business of the world for our own sake, because through that, and through contemplation in equal measure, our soul is purified and brought closer to the divine... Thought and deed conjoined are crucial... The attempt must be made; the outcome is irrelevant. Right action is a pale material reflection of the divine, but reflection it is, nonetheless. Define your goal and exert reason to accomplish it by virtuous action; successs or failure is secondary.

The immortality of the soul lies in its dissolution; this was the cryptic comment that so frustrated Olivier and which Julien had only ever grasped as evidence for the history of a particular school of thought. He had known all about its history, but Julia knew what it meant. He found the realization strangely reassuring.
Considering he was neither priest nor scholar, the young man gave sensible, thoughtful replies -- the more so, perhaps, for being untrained, for he had not learned what he should believe or should not believe. Present a statement to him in flagrant contradiction to all Christian doctrine and he could be persuaded to agree on its good sense, unless he remembered it was the sort of thing of which pyres are made for the incautious.
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.
