The more I have studied Lincoln, the more I have followed his thought processes, the more I am convinced that he understood leadership better than any other American president.

The big biography of Lincoln necessarily had to do so much with his political career, his ambitions, his accomplishments in public, with less time to spend on his private life, his inner life, and I thought this might be a way of getting at that.

I love mysteries, and I read them every night before I go to bed.

Maybe I will write a memoir, perhaps I'll do some essays, or maybe I will write a mystery story.

Lincoln had no such person that he could talk with. Often, as a result, he debated with himself, and he would draw up a kind of list of the pros and cons of an argument, and carefully figure them out, and he might test them in public.

In Lincoln's day a President's religion was a very private affair. There were no public prayer meetings, no attempts to woo the Religious Right. Few of Lincoln's countrymen knew anything at all of his religious beliefs.
