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

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

“Science fiction inspires scientists, but it doesn't exist to dictate what our future should look like. Great science fiction is fun to read and it makes you think, period. Claiming anything more than that is dicey. Grand visions of the future were more prevalent in the golden-age science fiction, but all fiction is a reflection of the current times. As science moves more quickly, the horizon of science fiction tends to recede closer to the present.”

“Science is my territory, but science fiction is the landscape of my dreams.”

“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 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.”
