When someone who's always been in your life is gone, it's a stunning adjustment of your own identity.

One hundred years from now, we'll all be dead. It's hard to believe. One hundred years from now, everyone we see every day will be gone.

We were very excited and we brought speakers in – then it so happened that there was a marine recruiter in the center of campus and one of our brothers, one SDS person put up a sign with a quote from the Nuremberg trial and an arrow point at the marine recruiter, saying, "This man is a war criminal." My younger brother and I, he was freshman and I was a sophomore, got caught up in the debates that were swirling around the center of campus and the young Trotskyists had put out a fact sheet on Vietnam that was phenomenal.

There was one moment when J. Edgar Hoover and us had the same distorted lens about who we were - "a real threat," you know? He thought so and we thought so and we were buddies in that regard.

The massive anti-war movement, which I was a part of and which was a major part of my life, never stopped the war in Vietnam.

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.

I don't think saying "I was wrong here, I was wrong there" absolves you of anything particularly, nor does it get you into heaven.
