“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.”

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

“Science fiction is the fiction of ideas. Ideas excite me, and as soon as I get excited, the adrenaline gets going and the next thing I know I’m borrowing energy from the ideas themselves. Science fiction is any idea that occurs in the head and doesn’t exist yet, but soon will, and will change everything for everybody, and nothing will ever be the same again. As soon as you have an idea that changes some small part of the world you are writing science fiction. It is always the art of the possible, never the impossible.”

“Science fiction is the art of the possible not the impossible.”

“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”

“Well, Montag, take my word for it, I've had to read a few in my time, to know what I was about, and the books say nothing! Nothing you can teach or believe. They're about non-existent people, figments of imagination, if they're fiction. And if they're non-fiction, it's worse, one professor calling another an idiot, one philosopher screaming down another's gullet. All of them running about, putting out the stars and extinguishing the sun. You come away lost.”
