The biggest surprise for me, without a doubt, was that the first black people who came to the United States weren't the 20 who arrived in Jamestown in 1619. All of us had been taught that. The first African came to Florida in 1513. And the huge shock is we know his name, Juan Garrido, and that he wasn't a slave. He was free!

I want to be a figure for prison reform. I think that the criminal justice system is rotten.

Because Lincoln is so closely identified with what it is to be American, everyone wants to claim him, to rewrite his story to satisfy their own particular needs.

In the old days, you lived in one neighborhood, you knew all your neighbors and your daughter married the guy next door. That was social and economic progress. That model is gone now. We also had a world order that was fraught but fairly stable.

Let's face it - think of Africa, and the first images that come to mind are of war, poverty, famine and flies. How many of us really know anything at all about the truly great ancient African civilizations, which in their day, were just as splendid and glorious as any on the face of the earth?

I believe in the law. I think we have a great system of justice. But I do think that system of justice has been corrupted by racism and classism. I think it's difficult for 'poor people' - poor white people, brown people - to be treated fairly before the law in the same way that upper-class people are.

It's fascinating how life works.
