The [Vietnam] war's gone on for three years. And we'd thought we'd ended it because we'd done exactly what we were told and what we told ourselves we'd had to do. We had a majority. We were against the war and this created a crisis for democracy and a crisis for the antiwar movement.

The responsibility for the risks we posed to others in some of our most extreme actions in those underground years never leaves my thoughts for long. The antiwar movement in all its commitment, all its sacrifice and determination, could not stop the violence unleashed against Vietnam. And therein lies cause for real regret.

Students for a Democratic Society was also affiliated with the civil rights movement everywhere.

I'm different in the sense that every minute of every day, I change. I'm thinking. But the basic principles that have powered me forward are still there. They're not different.

The end of Students for a Democratic Society is viewed by me and a lot of other people as a terrible sorry in many ways, tragic event even though I participated in it and played some role in it. But I regret a lot of that.

[The whole first year at university] was a great time for me and great time of awakening.

I mean the prime case that you can look at is Martin Luther King, who was only an activist for 13 years. But every year, he became deeper, more concerned, connecting more issues.
