“Doctors always think anybody doing something they aren't is a quack; also they think all patients are idiots.”

“I don't think literature would be possible in a determined world. We might go through the motions but the heart would be out of it. Nobody could then 'smile darkly and ignore the howls.' Even if there were no Church to teach me this, writing two novels would do it. I think the more you write, the less inclined you will be to rely on theories like determinism.

“The park was the heart of the city. He had come to the city – and with a knowing in his blood – he had established himself at the heart of it. Everyday he looked at the heart of it; every day; he was so stunned and awed and overwhelmed that just to think about it made him sweat. There was something, in the center of the park, that he had discovered. It was a mystery although it was in a glass case for everybody to see and there was a typewritten card over it telling all about it. But there was something the card couldn't say and what it couldn't say was inside him. He could not show the mystery to just anybody; but he had to show it to somebody. Who he had to show it to was a special person. This person could not be from the city but he didn't know why. He knew he would know him when he saw him and that he would have to see him soon or the nerve inside him would grow so big that he would be forced to steal a car or rob a bank or jump out of a dark alley onto a woman.”

“Faith comes and goes. It rises and falls like the tides of an invisible ocean. If it is presumptuous to think that faith will stay with you forever, it is just as presumptuous to think that unbelief will.”
