"Novelists talk about their characters starting to do things they didn’t expect them to. Well, I imagine every writer of biography or history, as well as fiction, has the experience of suddenly seeing a few pieces of the puzzle fit together. The chances of finding a new piece are fairly remote — though I’ve never written a book where I didn’t find something new — but it’s more likely you see something that’s been around a long time that others haven’t seen. Sometimes it derives from your own nature, your own interests. More often, it’s just that nobody bothered to look closely enough."

"On July 20, 1969, when Neil Armstrong, another American born and raised in southwestern Ohio, stepped onto the moon, he carried with him, in tribute to the Wright brothers, a small swatch of the muslin from a wing of their 1903 Flyer."

"Writing is thinking. To write well is to think clearly. That's why it's so hard."
