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

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.

Abraham Lincoln did have intellectual instincts, a tremendous curiosity on a broad range of subjects, and a near-photographic memory for what he read. He was, at the end of the day, a politician: politics were his heaven, said William Herndon. But Lincoln did take comfort in ideas and books, more so than almost any other president, and he went to books and ideas in moments of perplexity to sort things out. Philosopher, no, but thoughtful and "surprisingly well-read" for his day.

One thing which Stephen A. Douglas was temperamentally incapable of doing was admitting he was wrong. He always believed that 'popular sovereignty' - the core doctrine of the Kansas-Nebraska Bill - was the right solution to the slavery controversy; and even though it had failed to solve much of anything in Kansas and Nebraska, he stubbornly insisted that this was because it had never been adequately tested.

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.

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.

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.
