“Science fiction is the most important literature in the history of the world, because it's the history of ideas, the history of our civilization birthing itself. ...Science fiction is central to everything we've ever done, and people who make fun of science fiction writers don't know what they're talking about.”

“Most science fiction seemed to be written for people who already liked science fiction; I wanted to write stories for anyone, anywhere, living at any time in the history of the world.”

“You need to read more science fiction. Nobody who reads science fiction comes out with this crap about the end of history”

“Anything you dream is fiction, and anything you accomplish is science, the whole history of mankind is nothing but science fiction. ”

“Science fiction writers, I am sorry to say, really do not know anything. We can't talk about science, because our knowledge of it is limited and unofficial, and usually our fiction is dreadful.”

“As often I have been a science fiction writer writing science fiction for the community of science fiction readers, I am also, for good or ill, an American writing American literature to an American audience. Most fundamentally, though, I am a human being writing human literature to a human audience.”
