I'm anti-establishment. So all the labels, the reason that I keep joking and rejecting this idea that I'm liberal, well partly that's because I think of myself as a radical, and by that I mean, not even in the terms of Left-Right that you might imagine - but someone who wants to go to the root of problems.

We all want to believe this American pastoral, but there's more to it. We have to be willing to exile ourselves from the fantasies and the mythology that we create around ourselves, or we're doomed to kind of innocently blunder into every country in the world and murder people.

Injustice anywhere is an assault on all of us. That means that we all can get busy.

My father lived with me the last five years of his life and passed away of Alzheimer's, and at that point he was saying to anyone who would listen, "We all hated the war in Vietnam." Well, it was easy to hate the war in Vietnam 40 years on.

We're actually saying, here's a principle that I'd like to arc toward. That's a very different role in life. I didn't expect [Barack] Obama to go to the root of things. I didn't expect him to have a principled position on anything. I mean, just pay some moderate attention to the guy.

After I had known [Barack Obama] for a while, I remember saying to my partner, "You know, this guy is really ambitious, I think he wants to be Mayor of Chicago." That was the limit of my imagination.

I dropped out in '64. And I came back to Michigan, in '65. In 1965, when I came back I had never heard of Vietnam.
