Modern presidential debating only started with Richard Nixon and John F.Kennedy in 1960, although the proximity of that to the Lincoln-Douglas centennial is more than accidental. The reason is, I think, the medium. Abraham Lincoln and Stephen A. Douglas were talking, but the talking was in terms of logic, development, and reasoning. Television, as a medium, resists those qualities in speaking - it favors quick cuts, one-liners, and talking points. I think the modern debates are largely the prisoners of the televised medium

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.

I think, a general anxiety, after the end of the Cold War, to find a new basis for affirming American nationhood. And perhaps another, in plainer terms, is the lure of the approaching Abraham Lincoln bicentennial has been made a resurgence in interest in Lincoln.

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.

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.

I don't know that there has ever been a time when Abraham Lincoln didn't stand head-and-shoulders above all other presidents in the historians' eye. But relatively speaking, there have been peaks and a troughs. One peak was in the 1910s-20s; a major trough was in the 1970s-80s. We are certainly on a peak again, something which began in 1994 with Michael Burlingame's 'The Inner World of Abraham Lincoln,' which showed in fabulous detail how many new and untapped sources were available on Lincoln.
