The Greek tragedies and comedies are like a roadmap to all the ways in which trying to live this rich, full life can go wrong. You could get into a war. You could find that you have members of your family on the wrong side of a political crisis. You could be raped. You could find that your child has gone crazy because of some horrible experience she's had.

People don't just want to feel satisfied. They actually want to act.

There was a time, before I was in graduate school, when political philosophy pretty much ceased to exist. The positivists thought there were only two things you could do: conceptual analysis or empirical investigation. Any kind of political theory or even ethical theory was nonsense.

Singapore and China, which don't want to encourage democratic citizenship, are expanding their humanities curricula. These reforms are all about developing a culture of innovation and entrepreneurship.

The thing that I find so bad about anger is the desire for payback. Of course, it is very human to wish for revenge. Your mother has died in the hospital, and the first thought a lot of people have is, I'll sue the doctor. You feel helpless, and you think, I'm less helpless if I'm doing something active that makes someone else pay. And social media make it easy to inflict all kinds of pain on other people. But what good does it do?

To be a good human being is to have a kind of openness to the world, an ability to trust uncertain things beyond your own control, that can lead you to be shattered in very extreme circumstances for which you were not to blame. That says something very important about the condition of the ethical life: that it is based on a trust in the uncertain and on a willingness to be exposed; it’s based on being more like a plant than like a jewel, something rather fragile, but whose very particular beauty is inseparable from that fragility.

There are no general-interest media that all of us can tap into. I'm not a good person to talk to about social media. I just avoid it. I'm suspicious also of the culture of venting. But the bigger question is, How can we in this media world have a genuine civic conversation? I mean, look at Franklin Roosevelt. He had these radio talks that all Americans listened to, and there was a common civic conversation that came out of it.
