“The many mysteries boil down to three. There is the kind that can be solved: who planted the bomb? Will the travellers reach their destination? What is Mother's childhood secret? There is the supernatural: dark metaphysical forces, never to be fully exposed, yet hinting of themselves in a way that suggests the author could reveal more if he chose, and might do, in his next book. And there are the insoluble mysteries: what lies beyond life, what beauty is for, why the innocent suffer and the guilty prosper, what goes on in the heads of other people, why life keeps fucking us over just when we're doing all right -- these are the mysteries the books dealing with them can't solve, and it is for this reason that the best of these books are the ones we keep rereading.”

“But sometimes you can't figure everything out because you can't ever really understand other people. You can't understand why they do what they do. You just have to accept a little mystery, Ben. People are mysterious, the world is mysterious. You can't know everything. You're not supposed to. This isn't a history book. It's just the world. It's a messy place.”

“We're like mysteries to one another. Maybe if I can solve him and he can solve me, we can explain each other. Maybe that's what I need. Someone to explain me.”

“Love is the biggest mystery of the universe. But why try to solve it, when one simply view it for what it is and marvel at the wonders and strangeness it brings?”

“Unlike him I had been unable to escape into the simple complexities of science. All he had to do was solve the mystery of the universe, which may be difficult but is not as difficult as living an ordinary life...(How happy scientists are! Why didn't we become scientists, Percival? They confront problems which can be solved. We don't know what we confront. Does it have a name?)”

“Books have no life; they lack feeling maybe, and perhaps cannot feel pain, as animals and even plants feel pain. But what proof have we that inorganic objects can feel no pain? Who knows if a book may not yearn for other books, its companions of many years, in some way strange to us and therefore never yet perceived?”
