I admire Lincoln enormously and I think what's interesting about Lincoln is how he changes, it's not that he held the same view throughout his life.

A new future requires a new past.

Colonization was the idea that once slavery ended African-Americans should be encouraged - or required, in some people's view - required to leave the country. It's part of an attitude toward the abolition of slavery which says America should not be a slave society, but it can never be a multiracial society. You can never have free black and white people living together.

Lincoln sees slavery in some ways as a theft of labor. A slave is a laborer who is being denied the fruits of his labor.

A man working for wages his whole life is not really free. That is why Jefferson said, you have to own land. Southerners said, - and they weren't being hypocritical - they said slavery is the foundation of freedom because if you own slaves, you are freer yourself.

In the Shadow of Slavery covers two and a half centuries of black life in New York City, and skillfully interweaves the categories of race and class as they affected the formation of African American identity. Leslie Harris has made a major contribution to our understanding of the black experience.

I think here is the irony of American history. We don't have an established church. When you have an established church nobody takes religion as seriously as we do here. We have a free market in religion. The religious groups are competing with each other.
