From a 2011 BLDGBLOG interview with China Miéville:
. Novelists have an endless drive to aestheticize and to complicate. I know there’s a very strong tradition—a tradition in which I write, myself—about the decoding of the city. Thomas de Quincey, Michael Moorcock, Alan Moore, Neil Gaiman, Iain Sinclair—that type-thing. The idea that, if you draw the right lines across the city, you’ll find its Kabbalistic heart and so on.
The thing about that is that it’s intoxicating—but it’s also bullshit. It’s bullshit and it’s paranoia—and it’s paranoia in a kind of literal sense, in that it’s a totalizing project. As long as you’re constantly aware of that, at an aesthetic level, then it’s not necessarily a problem; you’re part of a process of urban mythologization, just like James Joyce was, I suppose. But the sense that this notion of uncovering—of taking a scalpel to the city and uncovering the dark truth—is actually real, or that it actually solves anything, and is anything other than an aesthetic sleight of hand, can be quite misleading, and possibly even worse than that. To the extent that those texts do solve anything, they only solve mysteries that they created in the first place, which they scrawled over the map of a mucky contingent mess of history called the city. They scrawled a big question mark over it and then they solved it.
Arthur Machen does this as well. All the great weird fiction city writers do it. Machen explicitly talks about the strength of London, as opposed to Paris, in that London is more chaotic. Although he doesn’t put it in these words, I think what partly draws him to London is this notion that, in the absence of a kind of unifying vision, like Haussmann’s Boulevards, and in a city that’s become much more syncretic and messy over time, you have more room to insert your own aestheticizing vision.
As I say, it’s not in and of itself a sin, but to think of this as a real thing—that it’s a lived political reality or a new historical understanding of the city—is, I think, a misprision.
BLDGBLOG: You can see this, as well, in the rise of psychogeography—or, at least, some popular version of it—as a tool of urban analysis in architecture today. This popularity often fails to recognize that, no matter how fun or poetic an experience it genuinely might be, randomly wandering around Boston with an iPhone, for instance, is not guaranteed to produce useful urban insights.
Miéville: Some really interesting stuff has been done with psychogeography—I’m not going to say it’s without uses other than for making pretty maps. I mean, re-experiencing lived urban reality in ways other than how one is more conventionally supposed to do so can shine a new light on things—but that’s an act of political assertion and will. If you like, it’s a kind of deliberate—and, in certain contexts, radical—misunderstanding. Great, you know—good on you! You’ve productively misunderstood the city. But I think that the bombast of these particular—what are we in now? fourth or fifth generation?—psychogeographers is problematic.
