“On a world where a common table implement is a little device with which you crack the ice that has formed on your drink between drafts, hot beer is a thing you come to appreciate.”

“A book is never, ever finished. You simply get to a point where you and your editor are reasonably happy with how it is and you go with that. Left to our own devices, a writer would endlessly fiddle with a book, changing little thing after little thing.”

“If someone gave you a device with which you could see entire worlds just by holding it in front of your eyes, worlds of such beauty and complexity that they took your breath away...wouldn't you want to show this device to everyone you knew?”

“All mathematicians live in two different worlds. They live in a crystalline world of perfect platonic forms. An ice palace. But they also live in the common world where things are transient, ambiguous, subject to vicissitudes. Mathematicians go backward and forward from one world to another. They’re adults in the crystalline world, infants in the real one.”

“The worst thing in the world can happen, but the next day the sun will come up. And you will eat your toast. And you will drink your tea.”

“It is a curious thing, but as one travels the world getting older and older, it appears that happiness is easier to get used to than despair. The second time you have a root beer float, for instance, your happiness at sipping the delicious concoction may not be quite as enormous as when you first had a root beer float, and the twelfth time your happiness may be still less enormous, until root beer floats begin to offer you very little happiness at all, because you have become used to the taste of vanilla ice cream and root beer mixed together. However, the second time you find a thumbtack in your root beer float, your despair is much greater than the first time, when you dismissed the thumbtack as a freak accident rather than part of the scheme of a soda jerk, a phrase which here means "ice cream shop employee who is trying to injure your tongue," and by the twelfth time you find a thumbtack, your despair is even greater still, until you can hardly utter the phrase "root beer float" without bursting into tears. It is almost as if happiness is an acquired taste, like coconut cordial or ceviche, to which you can eventually become accustomed, but despair is something surprising each time you encounter it.”
