“They were a susitute. They were what you did when you couldn't have what you wanted.”

“They make you settle for second best."That's what I like about the movies. There's always some minor character standing round to tell you the moral, just in case you're too dumb to figure it out for yourself."You never get what you want.”

“Don't they know science doesn't work like that? You can't just order scientific breakthroughs. They happen when you are looking at something you've been working on for years and suddenly see a connection you never noticed before, or when you're looking for something else altogether. Sometimes they even happen by accident. Don't they know you can't get a scientific breakthrough just because you want one?”

“You'd help if you could, wouldn't you, boy?" I said. "It's no wonder they call you man's best friend. Faithful and loyal and true, you share in our sorrows and rejoice with us in our triumphs, the truest friend we ever have known, a better friend than we deserve. You have thrown in your lot with us, through thick and thin, on battlefield and hearthrug, refusing to leave your master even when death and destruction lie all around. Ah, noble dog, you are the furry mirror in which we see our better selves reflected, man as he could be, unstained by war or ambition, unspoilt by-”

“When you're a writer, the question people always ask you is, "Where do you get your ideas?" Writers hate this question. It's like asking Humphrey Bogart in The African Queen, "Where do you get your leeches?" You don't get ideas. Ideas get you.”

“A Grand Design we couldn't see because we were part of it. A Grand Design we only got occasional, fleeting glimpses of. A Grand Design involving the entire course of history and all of time and space that, for some unfathomable reason, chose to work out its designs with cats and croquet mallets and penwipers, to say nothing of the dog. And a hideous piece of Victorian artwork. And us.”

“I’m not studying the heroes who lead navies—and armies—and win wars. I’m studying ordinary people who you wouldn’t expect to be heroic, but who, when there’s a crisis, show extraordinary bravery and self-sacrifice. Like Jenna Geidel, who gave her life vaccinating people during the Pandemic. And the fishermen and retired boat owners and weekend sailors who rescued the British Army from Dunkirk. And Wells Crowther, the twenty-four-year-old equities trader who worked in the World Trade Center. When it was hit by terrorists, he could have gotten out, but instead he went back and saved ten people, and died. I’m going to observe six different sets of heroes in six different situations to try to determine what qualities they have in common.”
