“No Eden valid without serpent.”

“I can't see that Danish episode as an adventure, or a crisis survived, or a serious quest for anything definable. It was just another happening like today's luncheon, something I got into and got out of. And it reminds me too much of how little life changes: how, without dramatic events or high resolves, without tragedy, without even pathos, a reasonably endowed, reasonably well-intentioned man can walk through the world's great kitchen from end to end and arrive at the back door hungry.”

“...you must have brought something. Books? I never saw you without a green bag of books.”

“It is the beginning of wisdom when you recognize that the best you can do is choose which rules you want to live by, and it's persistent and aggravated imbecility to pretend you can live without any.”

“Is that the basis of friendship? Is it as reactive as that? Do we respond only to people who seem to find us interesting?... Do we all buzz or ring or light up when people press our vanity buttons, and only then? Can I think of anyone in my whole life whom I have liked without his first showing signs of liking me?”

“Ambition is a path, not a destination, and it is essentially the same path for everybody. No matter what the goal is, the path leads through Pilgrim’s Progress regions of motivation, hard work, persistence, stubbornness, and resilience under disappointment. Unconsidered, merely indulged, ambition becomes a vice; it can turn an man into a machine that knows nothing but how to run. Considered, it can be something else — pathway to the stars, maybe. I suspect that what makes hedonists so angry when they think about overachievers is that the overachievers, without benefit of drugs or orgies, have more fun.”

“Some people, I am told, have memories like computers, nothing to do but punch the button and wait for the print-out. Mine is more like a Japanese library of the old style, without a card file or an indexing system or any systematic shelf plan. Nobody knows where anything is except the old geezer in felt slippers who has been shuffling up and down those stacks for sixty-nine years. When you hand him a problem he doesn't come back with a cartful and dump it before you, a jackpot of instant retrieval. He finds one thing, which reminds him of another, which leads him off to the annex, which directs him to the east wing, which sends him back two tiers from where he started. Bit by bit he finds you what you want, but like his boss who seems to be under pressure to examine his life, he takes his time.”
