Science fiction rarely is about scientists doing real science, in its slowness, its vagueness, the sort of tedious quality of getting out there and digging amongst rocks and then trying to convince people that what you're seeing justifies the conclusions you're making. The whole process of science is wildly under-represented in science fiction because it's not easy to write about. There are many facets of science that are almost exactly opposite of dramatic narrative. It's slow, tedious, inconclusive, it's hard to tell good guys from bad guys — it's everything that a normal hour of Star Trek is not.

Science fiction literature's focus is on ideas, the concept of change, and the impact on humanity. Those concepts are hard to capture on film. They work better in the mind.

Science fiction, because it ventures into no man's lands, tends to meet some of the requirements posed by Jung in his explorations of archetypes, myth structures and self-understanding. It may be that the primary attraction of science fiction is that it helps us understand what it means to be human.

I believe that many people read science fiction for a sense of participation in the wonders to come. The quest for non-ordinary reality is something more than curiosity and wishful thinking. We are too crowded in our every day lives by replicas of ourselves and by the repetitious artifacts of our days and nights. But we do not quite believe in this prosaic world. Continually we are reminded of the strangeness of birth and death, the vastness of time and space, the unknowability of ourselves. One would like to live differently, more significantly. One would like to participate in events more meaningful than our daily round, feel sensations more exquisite than is our usual lot. One reads science fiction in order momentarily to transcend the dull quality of everyday life.
There is a reason behind the search for the ineffable. The death of God is argued by the theologians; but for most of us it is a fact of everyday life. ‘God’ is a word with unfortunate connotations for many. By it I mean the fundamental mystery forever untouched by our rationality.…
This mystery is what we do not have any more. Our meagre substitute is the religion of man living on the Earth. We understand our ethical duties very well, we believe in them and try to follow them. But there is the secret sadness still remaining, the sense that we were born to quest, that our essence is unknowable, that we are plant and phantom, creatures of unknown dimensions. But all we come face to face with is our actual condition: we are ghosts smothered in bread and butter.

(Why science fiction?) Science fiction is the only genre that not only allows you to disregard everything that we're taught is realistic and practical, but actually demands that you do. So it allows us to move beyond the bounds of what is realistic and what is real, into the realm of the imagination, That is actually something that organizers do every single day.

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.

But science fiction’s entanglement with theology goes far deeper... Writers in this genre explore the consequences of technological innovation for human communities and individual human lives, whether those consequences are intentional or accidental, emotional or economic. They consider the impact that scientific theories and concepts have had on our understandings of what it means to be human, and on the limits of individual human identity. They examine how the characteristics that make us human (big brains, tool-making hands) might also lead to the end of humanity, either with a bang (“Terminator 3: Rise of the Machines”) or a whimper (“Day of the Triffids”) or both (“Threads,” “The Day After”). As such, science fiction asks its audiences not just who they think they are, but who they want to be. It creates visions both of the world as it could be and as it must not be allowed to be, with science and technology together building the future of faith.

Science fiction is important because it fights the natural notion that there's something permanent about things the way they are right now.

Science Fiction had made itself a part of the general debate of our times. It has added to the literature of the world ; through its madness and freewheeling ingenuity , it has helped form the new pop music, through its raising of semi religious questions, it has become part of the underworld where drugs, mysticism, God-kicks, and sometimes even murder meet ; and lastly , it has become one of the most popular entertainment in its own rights, a wacky sort of fiction that grabs and engulfs anything new or old for its subject matter, turning it into a shining and often insubstantial wonder.

Individual science fiction stories may seem as trivial as ever to the blinder critics and philosophers of today — but the core of science fiction, its essence, the concept around which it revolves, has become crucial to our salvation if we are to be saved at all.

Sci-fi was always understood to be politically based. It’s a way of setting up a political message in a format that people can digest. If you tell somebody “That person’s a liar,” they can say, “No, I saw him last week and I trust him.” But if you make them a reptile and give them the same information, they’ll say, “Yeah, he’s a reptile. They all lie.” That’s the great thing about sci-fi.

I think of us as a people who inoculate ourselves against a plague of insanity with a powerful anti-idiotic called science fiction. I think sf is a literature which by its very nature requires that you be at least a little sane, that you know at least a little something. You must abdicate the right to be ignorant in order to enjoy science fiction, which most people are unwilling to do; and you must learn, if not actually how to think things through, at least what the trick looks like when it's done. Frequent injections will keep a lot of madness away.

Science fiction is the search for a definition of mankind and his status in the universe which will stand in our advanced but confused state of knowledge (science), and is characteristically cast in the Gothic or post-Gothic mode.

I think Dr. Willis McNelly at the California State University at Fullerton put it best when he said that the true protagonist of an sf story or novel is an idea and not a person. If it is *good* sf the idea is new, it is stimulating, and, probably most important of all, it sets off a chain-reaction of ramification-ideas in the mind of the reader; it so-to-speak unlocks the reader’s mind so that the mind, like the author’s, begins to create. Thus sf is creative and it
inspires creativity, which mainstream fiction by-and-large does not do. We who read sf (I am speaking as a reader now, not a writer) read it because we love to experience this chain-reaction of ideas being set off in our minds by something we read, something with a new idea in it; hence the very best since fiction ultimately winds up being a collaboration between author and reader, in which both create and enjoy doing it: joy is the essential and final ingredient of science fiction, the joy of discovery of newness.
