I wish I knew as much about anything today as I knew about everything when I was twenty.

The first thing I did [in Michigan] was join a picket line of a pizzeria in Ann Harbor in 1963 that didn't allow African Americans to eat there.

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.

When I was arrested opposing the war in Vietnam in 1965, as I said about 20 or 30% of people were opposed to the war. By 1968, more than half of Americans were opposed to the war. If you pull in Europeans, Canadians, people from around the Third World, the war was vastly unpopular. But even half of Americans by 1968 opposed the war.

Can we imagine a different world? I can. That's a world where work is rational, it's in the common good, and we're actually producing real things rather than spinning our wheels in dreams of consumer heaven.

Chicago '68 was a relatively small demonstration for its time, but I've talked to millions of people who claim they were there because it felt like we were all there. Everyone from our generation was there and was at Woodstock.

Lyndon Johnson who was the president who was executing that war, announced in the spring of 1968 that he would not seek the presidency again. He would go to Paris and end the war in Vietnam. Well we were ecstatic.
