Knowledge is no guarantee of good behavior, but ignorance is a virtual guarantee of bad behavior.

You can’t really change the heart without telling a story.

The great philosophers of the past who wrote so beautifully - Rousseau, John Stuart Mill - had to write beautifully because they had to sell their work to journals. They had to sell books to the general public because they could not hold positions in universities. Mill was an atheist, and, therefore, could not hold a position in a university.

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.

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

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.

Today, I think, the state of philosophizing about democracy is very healthy. It bridges political science and philosophy, as it should.
