It would be pleasant to believe that some of Lincoln's DNA is actively swimming around in somebody's soup, but all the evidence is against it. And of course, there's always the risk that what we might get would be more Robert Todd Lincoln than Abraham Lincoln.

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.

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.

Patriotism without criticism has no head; criticism without patriotism has no heart.

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.
