“In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.”

“I think that things happen, and if you don't do something to change them, they just keep happening. Sometimes that's a good thing, and sometimes it's a nightmare.”

“You never think it will happen to you. You think about what it would be like. You go through it over and over in your mind, changing the scenario slightly each time, but deep down, you don't really believe it would ever happen, because it's something that happens to someone else, not to you.”

“I don't mind nothing happening in a book, but nothing happening in a phony way--characters saying things people never say, doing jobs that don't fit, the whole works--is simply asking too much of a reader. Something happening in a phony way must beat nothing happening in a phony way every time, right? I mean, you could prove that, mathematically, in an equation, and you can't often apply science to literature.”

“The strangest thing has happened. I really missed my dog. That's never happened to me before. You know, on a long tour you do hear people saying they miss their pets. I never have. But last night I started really missing my dog. It's very odd, 'cause I don't have a dog.”

“bad things, like good things don't happen any more often than they ought to by chance. the universe has no mind, no feelings, and no personality, so it doesn't do things in order to either hurt or please you. bad things happen because things happen.”
