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?

The humanities prepare students to be good citizens and help them understand a complicated, interlocking world. The humanities teach us critical thinking, how to analyze arguments, and how to imagine life from the point of view of someone unlike yourself.

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.

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.

As we tell stories about the lives of others, we learn how to imagine what another creature might feel in response to various events. At the same time, we identify with the other creature and learn something about ourselves.

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.

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