Since science fiction concerns the future of human society, the worldwide loss of faith in science and in scientific progress is bound to cause convulsions in the SF field. This loss of faith in the idea of progress, in a "brighter tomorrow," extends over our whole cultural milieu; the dour tone of recent science fiction is an effect, not a cause. If a modern science fiction writer mirrors this sense of doom, he is only doing what any responsible writer does: If a writer feels that present-day saber-rattling and drum-beating are leading the world to war, he has no choice but to reproduce his feelings in his writings -- unless he is writing purely for profit, in which case he never reproduces his feelings, only those sentiments that he feels will be commercially acceptable.
All responsible writers, to some degree, have become involuntary criers of doom, because doom is in the wind; but science fiction writers more so, since science fiction has always been a protest medium. In science fiction, a writer is not merely inclined to act out the Cassandra role; he is absolutely obliged to -- unless, of course, he honestly thinks he will wake up some morning and find that the high-minded Martians have sneaked off with all our bombs and armaments, for our own good.
Of course, doom stories become monotonous, since there are infinite bright, successful, nondoom futures, but only one doom; that is war. Once the war-doom story has been written, there is not much to say; and Ray Bradbury has written that story at least once. So the responsible science fiction writer repeats himself, since although there are many things he might write about, there is only one horrible future he really believes in: The rest are exercises in logic, imagination, and writing skill. If the writer honestly believes we are moving toward racial suicide, then skillful, cheerful stories become -- although interesting -- mere fiddle-scraping. But a natural hope, taking the place of legitimate optimism, crowds us into preferring these pleasant substitutes. Well, they are a lot of fun, just as detective novels were a lot of fun in the thirties. And the question is not: Which makes more enjoyable reading? Because nobody would seriously debate that one. After all, pleasant exercises in imagination and logic are supposed to be pleasant; and the doom stories are merely intended to call attention to reality. The latter activity has never been popular.
In a sense, the job of the science fiction writer in continuing to write pessimistically if he feels pessimistic, is a worsening of the spot every one of us is in; the SF writer will be cooked no deader than anybody else. But the SF writer has all day to brood; brooding, or at least thinking, is his job. If the SF writer is requested not to think about doom, if it's immoral to write about an approaching war, then it certainly is an evil thing to worry about it.
The only really legitimate complaint that can be raised against doom stories (outside of the complaint that they are all the same and hence only one really adequate doom story is required) is that there have always been war and danger, and that the sense of doom may be misplaced. This is a good argument, and I am beginning to believe it. A doom story never offers a solution to the problem: It merely utters the problem over and over again. Well, assuming we accept the existence of the problem (the approaching war), perhaps a more realistic or at least more valuable function would be to seek, in our science fiction stories, partial solutions to the menace. How are we going to survive? What will our world be like after a few (or a lot) of us have survived?
Rather than writing stories about doom, perhaps we should take the doom for granted and go on from there. Make the ruined world of ash a premise: State it in paragraph one, and get it over with, rather than winding up with it at the very end. And make the central theme or idea of the story an attempt by the characters to solve the problem of postwar survival.
At worst, we can suppose that nobody will survive. But this is like taking pictures of coal bins at midnight: It can be done, but if there is nothing there, then what the hell. It is quite possible that a few dozen and even a very large number of people may survive the war, in which case a story dealing with various attempts at setting up societies can be developed. Of course, we want to avoid the English doom novel: the struggling primitive colony of the postmachine type, the "back to nature" thing. Let's bypass that, and presume basic technology; maybe not atomic-powered rocket ships, but at least gasoline combustion engines and telephones.
However, I can't seriously believe that much of our cultural pattern or physical assets will survive the next fifty years. Our present social continuum is disintegrating rapidly; if war doesn't burst it apart, it obviously will corrode away. At the very best, at the most optimistic, there won't be any death and destruction. I'll assume the brighter side, the possibility of a limited war and only partial retrogression -- Bradbury is perhaps too pessimistic -- but to avoid the topic of war and cultural retrogression, as some schools of science fiction writers and editors have done, is unrealistic and downright irresponsible.
