When I came to Harvard, there were no tenured women except one, who was in a chair reserved for a woman. It's still an uphill battle, and I encountered great sexism in parts of my career, but I have to say that things are a lot better than they used to be. There are many women today doing wonderful work all over the academy.

It's not as though there aren't many, many art works and many other cultures, but there was something special about the civic nature of the Greek theater. All the citizens stopped working. They came into these theaters. It wasn't like a Broadway theater where you sit in the dark and you expect to be passively entertained. You're in this theater, amphitheater, in bright sunlight looking at your fellow citizens, recognizing their faces, and thinking with them about the future of your city. I think very few cultures have had a theatrical tradition that is quite so civic.

With the rise of capitalism, it became more obvious that people pursue individual self-interest. The great nationalist in Italy, Giuseppe Mazzini, a wonderful philosopher, said that we need the nation. We need something that people can lean on, from which they can then reach out to the whole world. The idea of all humanity is too vague. It can't motivate human aspiration in a reliable way.

A person in torment is not going to give you anything.

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.

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.

When a profession is protected by academic freedom and tenure, it tends to turn inward. To a large extent that's good.
