Art and activism can be symbiotic. They don't have to be, of course; they can also be contradictory.

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.

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.

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.

Let's look at two things real quickly: the civil rights movement in Mississippi in the Sixties and the Arab Spring starting in Tunisia and Cairo. What they had in common was people who were told, and who believed inside themselves, that they were a certain way, and the society at large believed it.

Terrorists destroy randomly.

Being an activist and an artist - those two things should go together. You should allow the artistic sensibility to control some of your activism, but never should it be allowed to paralyze you.
