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.

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.

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.

If you are going to abolish slavery, that opens up all these other questions: what system of labor is going to replace slave labor? What system of race relations is going to replace the race relations of slavery? Who is going to have power in the post-war South? The Emancipation Proclamation doesn't answer that question, but it throws [it] open.

I don't [even] know the number of books on Abraham Lincoln. Ten thousand, twelve thousand? I have seen various numbers. It seems like every generation is always trying to come to terms with Lincoln.

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.

Look, Mrs. McGillicuddy, it's not my fault your son jumped out a dorm room window on Christmas eve. I've written over fifty books as a Columbia professor, all right? You don't do that by holding hands with every at-risk undergraduate who says he's homesick, or he's turning gay, or the dog ate his term paper. I write about Lincoln, and freedom, and great ideas. I don't always have time for students. It's like Dean Martin used to say: if you want to talk, go to a priest. Hey -- what's the gun for?
