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.

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.

We are lucky in the United States to have our liberal arts system. In most countries, if you go to university, you have to decide for all English literature or no literature, all philosophy or no philosophy. But we have a system that is one part general education and one part specialization. If your parents say you've got to major in computer science, you can do that. But you can also take general education courses in the humanities, and usually you have to.

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

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.

We really have to think about aging because women are living longer than men. More of the people who need care are women. A lot of them are living alone, with no one to care for them, or they're shunted into institutions. I would like to see a sensible aging policy more like what the Nordic countries have. They're cutting back those programs, but there you can still have in-home nursing care. You don't have to rely on your children. I personally don't want to be a burden on my daughter.

Economists get impatient with philosophy. They are often trained as skilled mathematicians. They don't like going back to ordinary language and first principles.
