On those occasions when people ask me to define science fiction, I reference the above. Probably the most famous jump-cut in cinema. You already know the context, so I don't need to spell it out for you: millions of years BC, an apeman throws a bone into the sky. It flies upward. The camera pans with it, following it a little shakily into the blue sky. The bone reaches its apogee and, just as it starts to fall back down, Kubrick cuts to a shot of a spaceship in orbit in AD 2001.
Now, this seems to me an extremely beautiful and affecting thing, a moment both powerful and eloquent even though I'm not sure I could lay out, in consecutive and rational prose, precisely why I find it so powerful or precisely what it loquates. It is, I suppose, something ‘about’ technology, about the way humans use tools, our habit of intrusively (indeed, violently) interacting with our environments, about the splendor but also the limitation of such tools, the way even a spaceship is, at its core, a primitive sort of human prosthesis. But when you start explaining the cut in those terms you become conscious that you are losing something, missing some key aspect to what makes it work so well.
It works, in other words, not by a process of rational extrapolation, but rather metaphorically. I mean something particular when I say that, and I explain what I mean in detail below; but for now, and to be clear—I'm suggesting this moment actualizes the vertical ‘leap’ from the known to the unexpected that is the structure of metaphor, rather than the horizontal connection from element to logically extrapolated element that is the structure of metonymy. Kubrick's cut is more like a poetic image than a scientific proposition;——and there you have it, in a nutshell, my definition of science fiction. This genre I love is more like a poetic image than it is a scientific proposition.
Now, if my interlocutor needs more, and if the picture doesn't make my point, I might add something Samuel Delany-ish: about how science fiction is a fundamentally metaphorical literature because it sets out to represent the world without reproducing it.
The danger, here, is that people will take what I'm saying as a statement about the content of the genre, rather than what it is, a statement about the form, about the genre's discursive structure. So, for instance, Darko Suvin's common-sense definition of SF as determined by one or more "novums," things that exist in the SF text but not in the real world (and therefore not in texts mimetic of that real world) is too often, I think, treated only on the level of the content of the text. If a given novel or film contains a time machine or a faster-than-light spaceship or radically new concept of gender, then it is science fiction: end of. But what interests me about novums is the way the novum itself is so often a kind of reified or externalised embodiment of the formal logic of the metaphor, rather than just an, as it were, brute marker of difference as such.
Now, I need to acknowledge that most of the fans and critics of SF I know are not likely to be persuaded by what I say. More people, I think, would argue that a science fiction text extrapolates (more, or less, rigorously and quasi-scientifically) from knowns in our world into possibles in its imagined world. This is, on its face, perfectly sensible, and has the advantage of distinguishing ‘science fiction’, where the extrapolation needs to stay within broader guidelines of possibility, from ‘fantasy’ where magic, surrealism and so on may enter in to the equation. If you're writing about a colony on Mars, then you need to stick more-or-less within the bounds of what we know about Mars, and space travel, and humans-living-in-close-proximity and so on. Small deviations from probability may be permissible, depending on what they are and how cleverly the writer handles them; but large deviations are liable to ‘bounce’ the reader out of her reading experience. Coleridge's willing suspension of disbelief is harder to sustain (the argument goes) in a story where the protagonist is a captain in the Proxima-Centuraian Space Navy than one in which they work in a shoe-shop in Colchester, so writers need to tread carefully not to tip-over their readers' delicately balanced sensibilities.
I don't think that's true, actually; but plenty of clever and knowledgeable people do.
This approach to SF tends to lead to prioritizing things like: consistency and scope of world-building, plausibility, rationality, the scientific accuracy of the way novums are extrapolated from present-day knowledge and so on. But once we get in the habit of judging SF by these criteria, I would say we are moving away from what makes SF so cool and wonderful in the first place. Put world-building in the driving seat, as writer or reader, and Mike Harrison's clomping foot of nerdism comes stamping down on our human faces, forever.
Don't get me wrong: world-building, the correlative of ‘extrapolation’, certainly has its place in SF. Not in my definition of SF, though, and that's what concerns this post. It seems to me that world-building is ancillary to the crucial thing that makes SF (and Fantasy for that matter), vital, crucial and wonderful. I'm enough of a Tolkien fanboy to enjoy reading the appendices to The Lord of the Rings, but I'm not enough of a fool to believe the appendices to The Lord of the Rings are the point of that novel.
Put it this way: world-building is part of the system of a science fiction text; but the point of SF is not its system. The point is that it transports us—that it takes us somewhere new, that it brings us into contact with something wonderful, that it blindsides us, makes us gasp, unnerves or re-nerves us, makes us think of the world in a different way. I might differentiate a mediocre novum from a great one by saying that the former is embedded in a carefully worked-through and consistent web of world-building, where the latter achieves escape velocity.
Now, if I say the point of SF is transport and you immediately think of a well-integrated network of trains and buses, then it may be you're more persuaded by that view of SF as coherent rationally-extrapolated world-building. But if I say the point of SF is transport and you think rapture, well, conceivably you're closer to seeing the genre the way I do. Sometimes this transport is the full on mindblowing ‘Sense of Wonder’, a phrase I tend to take as a modern-day version of the venerable aesthetic category of the Sublime (to adapt Edmund Burke, we could say: mimetic fiction can be beautiful, but only SF can be sublime). Sometimes it is something smaller-scale, a woh! or cool!, a tingling in the scalp or the gut when we encounter something wonderful, or radically new, or strangely beautiful, or beautifully dislocating: something closer to Wordsworth's spots-of-time maybe. It needs to be at least flavoured with Strange (‘Weird’ as the kids used to say) to be properly SF. Great SF can never situate itself inside its readers' comfort zones, though commercially popular SF can and often does.
Fantasy has a related aesthetic uplift, which we might call ‘enchantment’, which can manifest in several ways, but which absolutely needs to be there, somewhere, in amongst your welter of maps and family-trees and invented languages and costumery and battles and elves and soap-opera-y comings and goings, if your Fantasy world is going properly to come alive.
Now, I cannot deny that there is an ideological element to my definition here (there's an ideological element to every definition, whether we acknowledge it or not). It's hardly news that the genre I love exists over a particular political fault line. There are many right-wing SF fans, who, speaking socially, prize proper authority, tradition, following the rules and a congeries of what are essentially military values, and who prefer SF that embodies all that. Which is fine; there's plenty of that kind of SF out there. For myself I have little time for the whole ‘the rules of physics prove my ideology is correct!’ crowd: the there's-no-such-thing-as-a-free-lunch crew, the ‘the pilot in The Cold Equations was right to throw that girl into space!’ cadre (together with their more deplorable ‘I cheered when the pilot in "The Cold Equations" threw that girl into space, serves the bitch right’ fringe). But there are many dedicated SF fans who find truth in some or all or those slogans. I can only speak for myself when I say I see SF as more fundamentally about the encounter with otherness, about hospitality to the alien, to the new and the strange and therefore with the marginal and the oppressed. This means it needs to embrace conventional and unconventional things, to be as much about gay as straight, trans as cis, colour as whiteness and so on. In all this I see SF as an art of disclosure, not enclosure. That's my ideological bias, and I'm content to own it.
I'll say two more things about my definition of SF as a fundamentally metaphorical literature. The first is to stress I'm not saying that (for example) SF's novums are symbols that can be decoded. I don't think so at all—that, as it were, the rocket ships are all symbolic penises, Hydra is a straightforward translation of Hitler's Nazi party and so on. This strikes me as a reductive and foolish way of reading texts. To repeat myself: it is not the content of any specific metaphor that defines SF for me; it is the structure of the metaphor as such. Mine is a formal, not a content-driven, definition. In order to explain what I mean by that, I'm going to bring in a little theory. Bear with me.
So here goes.
Roman Jakobson, one of the most influential linguistic theorists of the last century, makes what seems to me a really interesting and important distinction between metaphor and metonomy. Indeed, I hang my definition of science fiction upon that dyad. Metaphor is that trope that refers something to something it is not, invoking an implicit rather than explicit similarity between the word or phrase used and the thing described (a related but different trope is that of the simile, where words such as like or as are deployed): Achilles is a lion, all the world's a stage, chaos is a ladder and so on. Metonymy, on the other hand, is the rhetorical device by which a part of something is used to refer to the whole of something: a parish of a thousand souls, a hundred head of horse, calling the monarch ‘the crown’ and so on.
On a simple level, we recognise these rhetorical devices, and they take their place amongst the scores of other rhetorical devices that constitute our discourse. Jakobson, though, makes much more of them than this: although speech-acts and stories and novels only occasionally contain metaphors or metonomies, language as communication (he argues) is structured on a larger scale by the interplay between metaphor and metonomy. This is what he argues:
*The message construction is based on two simultaneous operations (the terms metonomy and metaphor are not used as figures of speech but rather as pervasive forces organizing language): Combination (horizontal)——constructing syntactic links; contexture. Relation through contiguity, juxtaposition. METONYMY: implying time, cause and effect, a chain of successive events
Selection (vertical)——choosing among equivalent options. Relation on basis of similarity, substitution, equivalence or contrast; synonym/antonym. METAPHOR: implying space, a-temporal connection, simultaneity. In poetry the projection of the principle of equivalence from the axis of selection (metaphor) is used as the major means of constructing a sequence (combination; metonym). This projection is the defining characteristic of poetry, and it expresses itself in rhyme, meter, symmetries, repetitions, motifs.
The dominant mode in the poetic is therefore that of metaphor. Whereas in Prose the metonym prevails, the chain of events, the plot, successive actions, a sequence of occurrences. (The opposition is not an absolute one, but rather a mark of a tendency).*
In fact, Jakobson developed his thought when he was working with autistic and asperger's-syndrome children. What he discovered was that these kids tended to understand metonymy, but tended to be baffled by metaphor. So, as it were, you could show them a headline that says the White House today issued a statement on immigration, and they would understand that ‘the White House’ was a metonym for the US Government. They wouldn't assume the actual building was talking (they're autistic, they're not stupid) but would, on the contrary, grasp the connection between the US Government and the White House, since the head of the US Government lives in the White House. In this case there's a logical connection, a conceptual copula, between A and B. But Jakobson discovered that if you said to them Achilles is a lion, they were liable to reply: no he's not, he's a man; and if you said Chaos is a ladder they'd stare at you like you were bonkers. Not, of course, that Jakobson's actual research involved him quoting Game of Thrones to autistic children. But you take my point.
I don't have hard data, and stand ready to be proved wrong by people who do, but I suspect that SF fandom contains a higher proportion of asperger's people than society as a whole. To be clear: such a statement is not a judgement. I have several friends on the spectrum, asperger's-wise, and they're clever, sensitive and wonderful people, precisely as worthwhile and valuable as people not on the spectrum. I make this observation to ask whether this might have something to do with why my way of defining SF is so marginal to how most of the fans and critics I know see the genre. Mine is an eccentric position, in the strict sense, and I know it: most fans who are happier with a metonymic model of the genre (extrapolation—which is to say, cause and effect, a chain of successive events—and world-building: coherence, links, contexture). It may be they're right,of course. But that's not how I define science fiction.
The structure of metaphor as such is the knight's-move, my favourite manoeuvre in chess. It leads you in a certain metonymic direction, and indeed sometimes leads you quite a long way down that consecutive path, in order to leap suddenly, not arbitrarily, but poetically, expressively, marvellously, in its unexpected direction. It's the way the carefully world-built society of Asimov's Nightfall falls apart under stellar Sublimity, or the way the intricate anthropological detail of Le Guin's Left Hand of Darkness is leavened by actual supernatural foretelling—a.k.a. magic—as a correlative to love, which is that novel's wondrous theme, wondrously handled. It's the way the scrupulously rational computational logic of Clarke's ‘Nine Billion Names of God’ steps, in its last sentence, into amazing impossibilities. It can be the beautifully unexpected outgoing, as when Ellie Arroway enters the alien world-construct at the end of Contact, or it can be the beautifully unexpected homecoming, as at the end of Kij Johnson's superb ‘26 Monkeys, Also the Abyss’. It doesn't need to happen at the end of a text: it might occur at the beginning (as when Timur's scouts ride through a wholly deserted Europe in Stan Robinson's Years of Rice and Salt) or anywhere in the text, actually. It is more affective than rational, more lyric than narrative (though the narrative is usually needful to generate its lyrical affect, I think). It is the hurled bone that turns, unexpectedly, impossibly yet somehow rightly, into a spaceship.
I'll finish on a personal note. I write, as well as write about, science fiction, and have been doing it for long enough to know that the kind of science fiction I write does not find favor with the majority of SF fans. How I define ‘Science Fiction’ may well have something to do with this: although it's just as likely that my relative lack of genre success is (Occam's razor and so on) because what I do just isn't very good. But this structure I'm describing here as formally constitutive of science fiction is also formally constitutive of the joke, and jokes are very, possibly unhealthily, important to me. The structure of a joke is a knight's move: it leads you along a particular narrative trajectory only to finish with a conjurer's flourish of the unexpected. The joke can't be capped with a merely random or left-field unexpectedness, or it won't be funny: but the flourish at the end (the, to deploy a term invented by a giant of genre, prestige) must work. Here's a joke:
A man walks into a library, goes up to the counter and says brightly: ‘I'd like fish and chips, please!’
And the woman behind the counter replies: ‘but ... but this is a library.’
The man's eyes go wide. ‘Oh, I'm sorry!’ he says. Then he leans forward and whispers: ‘I'd like fish and chips please.’
Here's another: my 9-year old son's favourite joke, as it happens.
There was once an inflatable boy. He lived in an inflatable house with his inflatable parents. He went to an inflatable school with all his inflatable friends. But one day he took a pin to school.
The headmaster summoned the boy to his office. Shaking his head sorrowfully he said: ‘you've let me down, you've let the school down, but most of all you've let yourself down.’
I'm absolutely not saying that SF needs to be full of jokes. Indeed, on the contrary, successful comedy-SF is very rare indeed (The Hitch-Hiker's Guide is really the only undisputed classic in this narrow field). I am not talking content, I am talking form; and the point of this form is that the unexpected twist releases a quantum of joy. That's why jokes are great, and that, although its content is very different, is why SF is great.
So when I call SF a metaphorical mode of art I mean it in that Jakobsonian sense: as a structural or formal constitution rather than anything content-level. And, in the unlikely situation that such a thing should be of interest to you, it provides the key to my own creative and intellectual exercises. Structuralism, metonymic and procrustean, interests me less than various poststructuralist freaks and shakes; irony (though it's currently rather out of fashion) interests me more than earnestness, play more than preachiness, epiphanies more than consistencies. I think our genre needs more Keatsian negative capability and fewer grids, hierarchies and certainties. SF is in the prestige, not in the setup and the performance, although the setup and the performance are needful for the prestige to come off. SF should transport us or what's the point of it. At any rate, that's how I define ‘Science Fiction’.
