People have a deep need to be legislators, and the idea of autonomy has become very precious.

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.

Radio was, in a way, a very philosophical medium. You could make an argument on the radio, and people listened to it. Television is already harder because people's attention span becomes shorter with television. Cut to a commercial and all that.

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

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.

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.

The EU might have become a large federal nation. But they would have had to do things differently. Number one, they would've had to make people feel like participants in a common project of autonomous law-giving. Much more political accountability, much more participation. That didn't happen, I think, because the movers and shakers were more concerned with economic union than political union.
