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.

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.

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.

The one who pursues revenge should dig two graves.

Abraham Lincoln did speak about keeping the man before the dollar, but he was talking at that moment about slavery, and referring to keeping the humanity of the slave higher in view than the self-interest of the slaveholders. This does not quite make Lincoln a challenger of the corporations; in fact, he prefaced those words by saying that Republicans were for the man AND the dollar.

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.

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.
