Change is the principal feature of our age and literature should explore how people deal with it. The best science fiction does that, head-on.
David Brin
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.
Ray Bradbury
I think the new science fiction, which other people apart from myself are now beginning to write, is introverted, possibly pessimistic rather than optimistic, much less certain of its own territory. There's a tremendous confidence that radiates through all modern American science fiction of the period 1930 to 1960; the certainty that science and technology can solve all problems. This is not the dominant form of science fiction now. I think science fiction is becoming something much more speculative, much less convinced about the magic of science and the moral authority of science. There's far more caution on the part of the new writers than there was.
J. G. Ballard
The aim of science is to discover and illuminate truth. And that, I take it, is the aim of literature, whether biography or history or fiction. It seems to me, then, that there can be no separate literature of science.
Rachel Carson
The great attraction of cultural anthropology in the past was precisely that it seemed to offer such a richness of independent natural experiments; but unfortunately it is now clear that there has been a great deal of historical continuity and exchange among those "independent" experiments, most of which have felt the strong effect of contact with societies organized as modern states. More important, there has never been a human society with unlimited resources, of three sexes, or the power to read other people's minds, or to be transported great distances at the speed of light. How then are we to know the effect on human social organization and history of the need to scrabble for a living, or of the existence of males and females, or of the power to make our tongues drop manna and so to make the worse appear the better reason? A solution to the epistemological impotence of social theory has been to create a literature of imagination and logic in which the consequences of radical alterations in the conditions of human existence are deduced. It is the literature of science fiction. ... [S]cience fiction is the laboratory in which extraordinary social conditions, never possible in actuality, are used to illumine the social and historical norm. ... Science fiction stories are the Gedanken experiments of social science.
Richard Lewontin
Why do so many people dislike science fiction? The answer goes like this: You have to think of science fiction in contrast to its nearest competitor, heroic fantasy. In heroic fantasy, by and large, things are pretty stable, and then some terrible evil comes along that's going to take over the world. People have to fight it. In the end they win, of course, so the earth is restored to what it was. The status quo comes back. Science fiction's quite different. With science fiction, the world's in some sort of a state, and something awful happens. It may not be evil, it may be good or neutral, just an accident. Whatever they do in the novel, at the end the world is changed forever. That's the difference between the two genres — and it's an almighty difference! And the truth is science fiction, because we all live in a world that's changed forever. It's never going to go back to what it was in the '60s or the '70s or the '30s, or whatever. It's changed.
