“I don't know anything but the simplest rules of English grammar, and I seldom consciously apply them. Nevertheless, I instinctively write correctly and, I like to think, in an interesting fashion. I know when something sounds right and when it doesn't, and I can tell the difference without hesitation, even when writing at breakneck speed. How do I do this? I haven't the faintest idea.”

“Writing, to me, is simply thinking through my fingers.”

“I made up my mind long ago to follow one cardinal rule in all my writing—to be clear. I have given up all thought of writing poetically or symbolically or experimentally, or in any of the other modes that might (if I were good enough) get me a Pulitzer prize. I would write merely clearly and in this way establish a warm relationship between myself and my readers, and the professional critics—Well, they can do whatever they wish.”

“I tell you it's deadly when you start thinking your wife might be right.”

“Don't you think it's rather nice to think that we're in a book that God's writing? If I were writing a book, I might make mistakes. But God knows how to make the story end just right--in the way that's best for us."Do you really believe that, Mother?" Peter asked quietly.Yes," she said, "I do believe it--almost always--except when I'm so sad that I can't believe anything. But even when I don't believe it, I know it's true--and I try to believe it.”

“We now know the basic rules governing the universe, together with the gravitational interrelationships of its gross components, as shown in the theory of relativity worked out between 1905 and 1916. We also know the basic rules governing the subatomic particles and their interrelationships, since these are very neatly described by the quantum theory worked out between 1900 and 1930. What's more, we have found that the galaxies and clusters of galaxies are the basic units of the physical universe, as discovered between 1920 and 1930....The young specialist in English Lit, having quoted me, went on to lecture me severely on the fact that in every century people have thought they understood the universe at last, and in every century they were proved to be wrong. It follows that the one thing we can say about our modern 'knowledge' is that it is wrong...My answer to him was, when people thought the Earth was flat, they were wrong. When people thought the Earth was spherical they were wrong. But if you think that thinking the Earth is spherical is just as wrong as thinking the Earth is flat, then your view is wronger than both of them put together.The basic trouble, you see, is that people think that 'right' and 'wrong' are absolute; that everything that isn't perfectly and completely right is totally and equally wrong.However, I don't think that's so. It seems to me that right and wrong are fuzzy concepts, and I will devote this essay to an explanation of why I think so.When my friend the English literature expert tells me that in every century scientists think they have worked out the universe and are always wrong, what I want to know is how wrong are they? Are they always wrong to the same degree?”

“There is nothing frightening about an eternal dreamless sleep. Surely it is better than eternal torment in Hell and eternal boredom in Heaven.”
