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.

No one loves an archive better than I do. I can smell a good one half-a-block away - all that brittle papyrus dust is music to my nostrils.

We still know so little about how the brain interacts with the body chemistry or, for that matter, whether we should be talking about the brain or the mind, that it would be perilous to hazard any guess about the way Abraham Lincoln's biological health may or may not have affected him. Of course, we don't have Lincoln on hand to ask him directly; but even if we did, we still might not be able to make sense of how all the parts worked together.

Corporate organization in American business and commerce was already well under way by the time Abraham Lincoln became president. But all the evidence from his pre-war lawyering days is that he had little objection to the rise of corporations. As a state legislator, he had strongly favored the creation of an Illinois state bank, as well as sponsoring the chartering of public/private corporations like the Illinois Central Railroad.

When I need to stretch my legs, I can walk across the street to the museum and relax among the illustrations of Abraham Lincoln's life, too. In a way, it reflects the halves of Lincoln's own character - one all jokes and buffoonery, the other all high-minded seriousness. If he could absorb both into his personality, I think I can, too.

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.

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.
