… science fiction is fundamentally a metaphorical literature, because it seeks to represent the world without reproducing it. Now the structure of metaphor as such is the knight’s move, my favourite manoeuvre in chess: leading you in a certain metonymic direction, the logically correct A to B to C, and indeed sometimes it leads you quite a long way down that consecutive path, but only in order to leap suddenly, not arbitrarily, but poetically, expressively, marvellously, in an 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 is the famous jump-cut in 2001: A Space Odyssey, when the hurled bone that turns, unexpectedly, impossibly, yet somehow rightly, into a spaceship.
The thing is: this structure I’m describing here as formally constitutive of science fiction is also formally constitutive of the joke. 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 must work. This is not to say that SF needs to be full of jokes to work. 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.
Adam Roberts on sf as a metaphorical literature. Mostly parking this for further thinking later on, when life is marginally less hectic; that form/content distinction he’s making seems like it could unpack in lots of interesting (and critically useful) ways.
I’m thinking in particular of an echo I’m getting from a riff of Clute’s in which he argues that capital-S Story “is inherently non-mimetic”; that Fantastika is coextensive with Story, and has “an inherent non-allegorical bent”, being a genre wherein the work “is a kind of representation of itself”; that Fantastika is “pure Story: not a lesson, but the thing told”. As I recall, Clute denies sf as being inherently metaphorical, but I think perhaps he and Roberts understand that term slightly differently; the form of the joke, after all, is also “not a lesson, but the thing told” (or so it seems to me).
The Roberts riff on the magician’s flourish above also opens up the possibility of rereading Priest’s The Prestige as a work of metagenre… though I suspect that doing so would only incur the writer’s wrath.
