“An honest religious thinker is like a tightrope walker. He almost looks as though he were walking on nothing but air. His support is the slenderest imaginable. And yet it really is possible to walk on it.”

“It was America, after all. The sort of place where you should be allowed to walk as high as you wanted. But what if you were the one walking underneath? What if the tightrope walker really had fallen? It was quite possible that he could have killed not just himself, but a dozen people below. Recklessness and freedom - how did they become a cocktail?”

“Any tightrope walker can walk in a straight line and hold a cane at the same time. It's the balancing on the rope at those dizzying heights that they have to practise”

“The terrible thing about love is that it takes away your safety net, your balancing pole. Even the tightrope you walk upon will disappear beneath you, yet love expects you to keep walking anyway, arms outstretched, one foot after the other, on nothing more than air.”

“The police, he imagined, were now walking around the parked car. He imagined their bandit chaser was parked beside the car and now they were walking around it and looking at it and not saying anything. Now they were inside it. They would see the interior of the automobile. They were tremendous, these police, because the next thing they would do was to look at each other. They would look around at the night air. They would just stand there. The police, he told himself, were marvelous when it came to just standing there. Sometimes they elaborated on it a little and pushed their caps back and forth on their heads. Nobody could push a cap back and forth on his head like a policeman.”

“Walkers are 'practitioners of the city,' for the city is made to be walked. A city is a language, a repository of possibilities, and walking is the act of speaking that language, of selecting from those possibilities. Just as language limits what can be said, architecture limits where one can walk, but the walker invents other ways to go.”
