“Science Fiction is the fiction of ideas.”

“In the face of all this, many of the standard ideas of science fiction seem to me to pale by comparison. I see the relative absence of these things and the distortions of scientific thinking often encountered in science fiction as terrible wasted opportunities. Real science is as amenable to exciting and engrossing fiction as fake science, and I think it is important to exploit every opportunity to convey scientific ideas in a civilization which is both based upon science and does almost nothing to ensure that science is understood.”

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

“This is an exercise in fictional science, or science fiction, if you like that better. Not for amusement: science fiction in the service of science. Or just science, if you agree that fiction is a part of it, always was, and always will be as long as our brains are only miniscule fragments of the universe, much too small to hold all the facts of the world but not too idle to speculate about them.”

“Science fiction offers its writers chances of embarrassment that no other form of fiction does.”

“It is said that science fiction and fantasy are two different things. Science fiction is the improbable made possible, and fantasy is the impossible made probable.”

“There is no such thing as science fiction, there is only science eventuality.”

“If contemporary literary fiction doesn't read a bit like science fiction then it's probably not all that contemporary, is it”

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

“No matter how various the subject matter I write on, I was a science-fiction writer first and it is as a science-fiction writer that I want to be identified.”
