“If you are really a product of a materialistic universe, how is it that you don't feel at home there?”

“Well, whatever they say, you don't feel like ghosts.”

“You never know how much you really believe anything until its truth or falsehood becomes a matter of life and death to you.”

“You can never be really sure of how much you believe anything until its truth or falsehood becomes a matter of life or death to you.”

“Being nice doesn’t make you stupid. It makes you feel good because you know you are gracious enough to forgive and smart enough to realize how distasteful some people can be.”

“In writing. Don't use adjectives which merely tell us how you want us to feel about the thing you are describing. I mean, instead of telling us a thing was "terrible," describe it so that we'll be terrified. Don't say it was "delightful"; make us say "delightful" when we've read the description. You see, all those words (horrifying, wonderful, hideous, exquisite) are only like saying to your readers, "Please will you do my job for me."[Letter to Joan Lancaster, 26 June 1956]”

“The universe rings true whenever you fairly test it.”
