When I read the article [in The New Yorker] by David Grann, I was very struck by people responding to the article, of people thinking I was such a hero and what a wonderful person I was, and I didn't feel that at all.

Up until the middle of the nineteenth century, men of science were all believers. Most of the great early English naturalists were also ministers; they were the only ones who had education and leisure for such pursuits. Darwin himself almost became a minister. God's power was always thought to be most easily and obviously revealed in the majestic works of nature.

That's your friend. My husband is my best friend. He's not the mirror that holds up my flaws. He's just the guy who's like, 'I think you're terrific'... It's just simple, showing up for each other.
