Children grow rapidly, forget the centuries-long embrace from their parents, which to them lasted but seconds. Children become adults, live far from their parents, live their own houses, learn ways of their own, suffer pain, grow old. Children curse their parents for their wrinkled skin and hoarse voices. Those now old children also want to stop time, but at another time. They want to freeze their own children at the center of time.

I'm still happy with the way Einstein's Dreams came out. That book came out of a single inspiration. I really felt like I was not creating the words, that I was hearing the words. That someone else was speaking the words to me and I was just writing them down. It was a very strange experience. That can happen with a short book. I don't think it could happen with a long book.

When I used to play golf. It's a terrible miserable game. It's incredibly frustrating. In 18 holes you make 150 horrible shots off in the woods, in the water...You make one good shot and it brings you back the next time. With writing a long book there has to be at least one bit that has some magic in it that you can go back to.

I picked such seemingly disparate essays, I thought it was important to say what was the guiding principle in the selection rather than focus on any one essay. I reached for some principle that had been subconscious in me and lifted it into consciousness. Authenticity and sincerity were the most important unifying principles of all these apparently different essays.
