Now in my view, if you were to line up the Presidents in the order of who made the greatest accomplishments, you'd put Lyndon Johnson in that arena with both Roosevelts probably, and [Abraham] Lincoln and so on. But the idea that Lyndon Johnson was operating as a free agent and coming up with these ideas on his own is nonsense.

[Martin Luther King] King was a socialist and King was an activist who was really a radical by the end.

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.

I see [Lyndon] Johnson as the war in Vietnam, and the invasion of the Dominican Republic and so on. So I'm not a liberal in that sense, because i think of liberals as part of that establishment.

That's in the nature of social change. So you can analyze what didn't work, but it's very hard to predict what will work.

If you were against slavery in 1840 and a white person, you would have been against the law, the Bible, your church, your pastor, your parents, common sense, tradition, everything. You would have been against everything.

All that means to me is that people who have a vision of a better world have a responsibility to open their eyes, to pay attention, to act on what the moment demands, and to be humble about that action.
