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.

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.

You pick up very well-known books on Lincoln [and] you will find almost no reference to his long-term belief in colonization. Why? Because it doesn't fit the image of the Great Emancipator. It doesn't fit the retrospective view we want to have of Lincoln as the man who was the moralist in politics, who came into office committed to ending slavery and waited to sign this document.

For historians, hindsight can be a treacherous ally. Enabling us to trace the hidden patterns of past events, it beguiles us with the mirage of inevitability, the assumption that different outcomes lay beyond the limits of the possible.

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.

Whenever you think of Lincoln as a historian, in his own mind, he becomes the Great Emancipator. This is his role in history henceforth. He was an ambitious man who wanted to make an impact on history, and this is how he did it.

Lincoln has accepted America as a biracial society. He's talking about giving at least some black men the right to vote. In the Emancipation Proclamation he advises some blacks to labor faithfully for reasonable wages, here in the United States. He doesn't say anything about them leaving the country. He puts black men in the army. That is a whole different vision than simply saying "let's have them go out of the country." I think what's interesting is the change in Lincoln's view, but one must realize that he did adhere to this idea of colonization for many years.
