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.

I think the best thing that I collect is memories. I love traveling; I love remembering stuff, my family, my daughter, my wife. I just love collecting memories of my trips, my experiences. And I think that's it. I'm not very glued to material stuff.

However important it is that love shall precede marriage, it is far more important that it shall continue after marriage.

I don't like to search too much. I find it is easier when romance finds you.

I once looked over the shoulder of a friend on Facebook and it looked like hieroglyphs to me. There's merit online, of course, but social media gets super freaky. Imagine if three generations from now, people online have forgotten what date or day of the week it is.
