“I don't think humanity just replays history, but we are the same people our ancestors were, and our descendants are going to face a lot of the same situations we do. It's instructive to imagine how they would react, with different technologies on different worlds. That's why I write science fiction -- even though the term 'science fiction' excites disdain in certain persons.”

“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.”

“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.”

“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.”

“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.”

“I don’t think there’s any border between science and art. All the fiction films I have made were always on the same subject,—a discovery of the “Other,” an exploration of difference.”
