As human beings, we ought to be vulnerable. We shouldn't try to say that we can be self-sufficient or do everything that's necessary for a good life on our own, because we need other people.

Disgust relies on moral obtuseness. It is possible to view another human being as a slimy slug or a piece of revolting trash only if one has never made a serious good-faith attempt to see the world through that person’s eyes or to experience that person’s feelings. Disgust imputes to the other a subhuman nature. How, by contrast, do we ever become able to see one another as human? Only through the exercise of imagination.

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

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.

I am a very big fan of the nation, actually. In Cicero's time, there was this idea that although we were members of the whole world of human beings, we also needed to connect our imaginations to a smaller unit. The smaller unit was something we knew we could live or die for, as Cicero died for the Roman republic.

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.

I think that's what we really need in America, for people to hear each other. And I think philosophy could do a little bit better on that.
