“There's no peace like the peace of an inner courtyard on a sunny day.”

“There's nothing like the unimaginable to make people believe.”

“A good zoo is a place of carefully worked-out coincidence: exactly where an animal says to us, "Stay out!"...we say to it, "Stay in!" with our barriers. Under such conditions of diplomatic peace, all animals are content and we can relax and have a look at each other.”

“Slice a pear and you will find that its flesh is incandescent white. It glows with inner light. Those who carry a knife and a pear are never afraid of the dark.”

“The three-toed sloth lives a peaceful, vegetarian life in perfect harmony with its environment. A good-natured smile is forever on its lips...I have seen that smile with my own eyes. I am not one given to projecting human traits and emotions onto animals, but many a time during that month in Brazil, looking up at a sloth in repose, I felt I was in the presence of upside-down yogis deep in meditation or hermits deep in prayer, wise beings whose intense imaginative lives were beyond the reach of scientific probing.”

“If there's only one nation in the sky, shouldn't all passports be valid for it?”

“You might have noticed that I have been sending you used books. I have done this not to save money, but to make a point which is that a used book, unlike a used car, hasn't lost any of its initial value. A good story rolls of the lot into the hands of its new reader as smoothly as the day it was written. And there's another reason for these used paperbacks that never cost much even when new; I like the idea of holding a book that someone else has held, of eyes running over lines that have already seen the light of other eyes. That, in one image, is the community of readers, is the communion of literature.”
