Jane Addams, founder of Hull House, once asked, "How shall we respond to the dreams of youth?" It is a dazzling and elegant question, a question that demands an answer--a range of answers, really, spiraling outward in widening circles.

I think that you're smarter than we were, but we had two things: one is, in our naïveté we believed we could change the world. And number two, we believed that another world was possible. And once that belief took hold of some critical mass, a tiny minority nonetheless, but a critical mass of people, then the world did change.

If the logic of capitalism is "expand or die," then either it has to die or the world has to die.

If you read Martin Luther King speeches and sermons in the last two years of his life - you might want to - –when I read these to my students, they think it's Malcom X because it's so radical. And if you read nothing else - if your viewers read nothing else - then the April 4, 1967, speech at Riverside Church called "Beyond Vietnam," that's where he says the greatest purveyor of violence on earth is my country. And he connects the triplets of evil, racism, militarism, and materialism, and that connection makes him a radical.

I wish I had been wiser. I wish I had been more effective, I wish I'd been more unifying, I wish I'd been more principled.

What we need is a gigantic, messy community conversation about what is teaching and learning for the 21st century. We need to engage communities.

I don't think of myself as a particularly nostalgic person.
