Abraham Lincoln would have been happy to have solved the slavery problem by compensation - in fact, drew up a gradual, compensated emancipation plan as early as November, 1861 - but no slaveholders were willing to go along with it.

It's often said that leadership is the art of getting people to do what you want, and making them think it's what they want. This captures a lot of what Abraham Lincoln did.

I suppose I've been interested in Abraham Lincoln for almost as long as I can remember. My first Lincoln book was the Classics Illustrated comic book version of the life of Lincoln, and with that, I was hooked.

The best one-volume biography of Abraham Lincoln is still Benjamin Thomas's 1952 biography. David Donald's 1995 biography is a close second, and close enough that if you can only obtain the Donald rather than the Thomas, your book club will still be doing just fine.

Until the early 90s, when I was working on a project about the idea of free will in American philosophy. I knew that Lincoln had had something to say about "necessity" and "fatalism," and so I began writing him into the book. In fact, Lincoln took over. I wrote instead 'Abraham Lincoln: Redeemer President,' in 1999, and I've splitting rails with Mr. Lincoln ever since. If there's a twelve-step process for this somewhere, I haven't found it yet.

Corporations did not achieve the scale we normally associate with them until the 1880s; but it's still hard to imagine that Abraham Lincoln would offered much in the way of determined opposition. William Herndon said that they always thanked the Lord when a corporation came knocking at their office door to hire them.

Stephen A.Douglas was a risk-taker by temperament; I expect that Lincoln - Douglas debates represented another risk he just couldn't resist. He lived to regret it.
