There's an interesting (but woefully short) interview with Neal Stephenson
on the Sci Fi Wire. In it, he talks about his decision to include an introduction and glossary of terms (an excerpt
of which is available) in his new novel:
People who do read science fiction and fantasy have developed a skill set that other people don't necessarily have. They can pick up a book and begin reading it, and it will have all of these words that they have not seen before and names that they are not familiar with, and it's set in a world whose geography they don't know and whose customs they don't know--and it can be a bit hard to follow at first, but those kinds of people know that if they just keep reading and are patient, over time all of that will be explained, and they will be able to piece it together in their heads. And doing that is actually part of the pleasure of reading such a book for a fantasy or science fiction fan.
This instantly reminded me of Eric Raymond's excellent essay, SF Words and Prototype Worlds
, in which he notes the way that SF can use a single word to embed broad and far-reaching implications into a story.
In looking at an SF-jargon term like, say, "groundcar", or "warp drive" there is a spectrum of increasingly sophisticated possible decodings. The most naive is to see a meaningless, uninterpretable wordlike noise and stop there.
The next level up is to recognize that uttering the word "groundcar" or "warp drive" actually signifies something that's important for the story, but to lack the experience to know what that is. The motivated beginning reader of SF is in this position; he must, accordingly, consciously puzzle out the meaning of the term from the context provided by the individual work in which it appears.
The third level is to recognize that "ground car" and "warp drive" are signifiers shared, with a consistent and known meaning, by many works of SF -- but to treat them as isolated stereotypical signs, devoid of meaning save inasmuch as they permit the writer to ratchet forward the plot without requiring imaginative effort from the reader.
Viewed this way, these signs emphasize those respects in which the work in which they appear is merely derivative from previous works in the genre. Many critics (whether through laziness or malice) stop here. As a result they write off all SF, for all its pretensions to imaginative vigor, as a tired jumble of shopworn cliches.
The fourth level, typical of a moderately experienced SF reader, is to recognize that these signifiers function by permitting the writer to quickly establish shared imaginative territory with the reader, so that both parties can concentrate on what is unique about their communication without having to generate or process huge expository lumps. Thus these "stereotypes" actually operate in an anti-stereotypical way -- they permit both writer and reader to focus on novelty.
At this level the reader begins to develop quite analytical habits of reading; to become accustomed to searching the writer's terminology for what is implied (by reference to previous works using the same signifiers) and what kinds of exceptions and novelties convey information about the world and the likely plot twists.
It is at this level, for example, that the reader learns to rely on "groundcar" as a tip-off that the normal transport mode in the writer's world is by personal flyer. At this level, also, the reader begins to analytically compare the author's description of his world with other SFnal worlds featuring personal flyers, and to recognize that different kinds of flyers have very different implications for the rest of the world.
For example, the moderately experienced reader will know that worlds in which the personal fliers use wings or helicopter-like rotors are probably slightly less advanced in other technological ways than worlds in which they use ducted fans -- and way behind any world in which the flyers use antigravity! Once he sees "groundcar" he will be watching for these clues.
The very experienced SF reader, at the fifth level, can see entire worlds in a grain of jargon. When he sees "groundcar" he associates to not only technical questions about flyer propulsion but socio-symbolic ones but about why the culture still uses groundcars at all (and he has a reportoire of possible answers ready to check against the author's reporting). He is automatically aware of a huge range of consequences in areas as apparently far afield as (to name two at random) the architectural style of private buildings, and the ecological consequences of accelerated exploitation of wilderness areas not readily accessible by ground transport.
Fascinating stuff. I don't have much to add, except that September 9 can't get here fast enough...
