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.

You cannot live a political life, you cannot live a moral life if you're not willing to open your eyes and see the world more clearly. See some of the injustice that's going on. Try to make yourself aware of what's happening in the world. And when you are aware, you have a responsibility to act.

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.

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.

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.

Teaching has always been, for me, linked to issues of social justice. I've never considered it a neutral or passive profession.

I do think [Barack Obama's] strategy for re-election is so misguided. He's counting on the Republicans to self-destruct, and they might, you know, but they might not. So he might be a one-term president.
