“Science fiction, outside of poetry, is the only literary field which has no limits, no parameters whatsoever.”

“I write fantasy. The only science fiction I have written is Fahrenheit 451. It's the art of the possible. Science fiction is the art of the possible. It could happen. It has happened.”

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

“Bob Dylan: The media is all-pervasive. What can a writer think of to write that you don't see every day in a newspaper or on television?
Interviewer: …Do you think that TV and the media have killed poetry and literature?
Bob Dylan: Oh, absolutely. Absolutely. … What's a writer to do if every idea is exposed in the media before he can get to it or let it evolve? What's a writer gonna write about? … We're living in a science-fiction world. We're living in a world that Disney has conquered. Disney's science fiction. Theme parks, trendy streets, it's all science fiction. So I would say, if a writer has got something to say, he'll have to do it in that–
Interviewer: Outside of the real world?
Bob Dylan: There is a real world. Science fiction has become the real world. Whether we realize it or not, it has.”

“The science fiction stories are not for the promotion of science and are not only science stories; but stories.”

“[Science fiction is] out in the mainstream now. You can tell by the way mainstream literary authors pillage SF while denying they're writing it!”

“Prediction of the future is possible only in systems that have stable parameters like celestial mechanics. The only reason why prediction is so successful in celestial mechanics is that the evolution of the solar system has ground to a halt in what is essentially a dynamic equilibrium with stable parameters. Evolutionary systems, however, by their very nature have unstable parameters. They are disequilibrium systems and in such systems our power of prediction, though not zero, is very limited because of the unpredictability of the parameters themselves. If, of course, it were possible to predict the change in the parameters, then there would be other parameters which were unchanged, but the search for ultimately stable parameters in evolutionary systems is futile, for they probably do not exist… Social systems have Heisenberg principles all over the place, for we cannot predict the future without changing it.”

“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.”

“In seeking scientific understanding of the processes of information transfer we have had to go considerably outside the subject limits within which 'information science' as an academic subject is normally constrained… It has become increasingly clear that only by widening its “knowledge base” can information science establish a solid foundation for future development.”

“Science Fiction has rivets, fantasy has trees.”
