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.

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.

Lincoln was a modernizer, so to speak. He believed in economic development. As a Whig before the war he favored what we would call infrastructure spending, government appropriation for canals, railroads, river and harbor improvements, and a tariff to protect industry. He believed in this market revolution that was sweeping across Northern society. He himself benefited from it in his own 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.

In a democratic society, as Max Weber said, what is possible is only possible because some people have demanded the impossible. The abolitionists helped to create a public discourse in which men like Lincoln become possible. That doesn't mean Lincoln is an abolitionist. It means there is a public opinion out there which is being influenced by antislavery sentiment.

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.
