In 1975, which was the height of the women's movement, I thought I'd write a book on women's history. But in searching for a topic, I realized that there were few places in history where men and women interacted. Finally, it hit me: 'Oh, look at the family. That's the one place.'

There is no denying that we have made great progress toward gender equality.

Feminism insists on women's right to make choices - about whether to marry, whether to have children, whether to combine work and family or to focus on one over the other. It also urges men and women to share the joys and burdens of family life and calls on society to place a higher priority on supporting caregiving work.

Feminism needs a political program because gender inequality has been fostered by political decisions.

In my early twenties, I got the basics covered. In retrospect, one of the great things about success is that I never really had to work in a factory full-time. So that's a blessing.

Credit comes with success, and I need to have a lot more of it. In due time - I'm not rushing.

People in the Pentagon had colleagues killed and maimed by bin Laden. They're trying to find bin Laden and kill him and his cult. Naturally they consider that a legitimate thing to do, but they're having mixed success at the job.

When I became successful, I put up a caution. I didn't think it was fair to have the shadow of that kind of success thrown on my family. And I was cautious about being taken by things that could destroy you.
