“Science fiction is no more written for scientists than ghost stories are written for ghosts.”
Penguin Science Fiction (1961) Introduction

“A good science fiction story should be able to predict not the automobile but the traffic jam.”

As quoted in The Making of Kubrick's 2001 (1970) by Jerome Agel, p. 300
1970s
Context: One of the biggest roles of science fiction is to prepare people to accept the future without pain and to encourage a flexibility of mind. Politicians should read science fiction, not westerns and detective stories. Two-thirds of 2001 is realistic — hardware and technology — to establish background for the metaphysical, philosophical, and religious meanings later.
As quoted in The Issue at Hand: Studies in Contemporary Magazine Science Fiction (1964) by James Blish, p. 14

“Science Fiction is the fiction of ideas.”
The Paris Review interview (2010)
Context: 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.
