Over the course of many years of micturating into all manner of urinals (and, it must be said, the occasional sink, as well) from Buenos Aires to Brooklyn, my attention has been drawn again and again to the peculiar little devices that affix the stalls or the little barriers (the little planes of pressed metal that separate urinator from fellow urinator, presumably to prevent the awkward social encounters of standing exposed before complete strangers without a barrier to mitigate). I am speaking of what, in an unlovely phrase, must be called “bathroom screws”—the strange anti-theft screws used in public bathrooms. These screws are neither philips head nor flat head screws. These are what are called in the industry “hex” or “security torx” or “spanner head” (aka, “snake eye”) screws. These are screws that look usually like this * or this : (But not like the more familiar this – or this +. They are designed to prevent “you,” the faceless, nameless, and disembodied citizen from disassembling the bathroom, because you don’t have the right tools. This, it seems to me, is interesting.
To the type of person who is given to free ranging, loosely analytical reflections upon all the strange things that the world casts is his way, who finds himself attracted to strange little disturbances in the otherwise smooth surfaces of everyday life (things like the creative defacement of public advertisements, unpicked up dog poo on the sidewalk, the strange guy on the subway, the unexpected pattern of ice crystals on my kitchen window, and so forth), these bathroom screws have been a point of particular and considerable interest. What, the querulous mind asks, do these screws assume? And what do they imply?
Walter Benjamin was excited by the prospects of applying historical-materialist (or “Marxist, really, I suppose) analysis to everyday life. He thought that one of the great challenges of the age (his age, which is still, in some sense, “our” age, even if the mechanics of reproduction have gone all ethereal and immaterial) was to “assemble large-scale constructions out of the smallest and most precisely cut components. Indeed, to discover in the analysis of the small individual moment the crystal of the total event.” What I take him to mean is something to the effect that we need to pay attention to how the little details of our experience can, if we pay proper attention to them, tell us something important about the larger world. These are what might be called “clues.”
A favorite professor (of sociology) once dropped this little iridescent observation in passing, which I immediately dutifully wrote down: “you can read a person’s class by paying attention to two things: their shoes and their watch.” These days, things have gotten much slipperier. No one wears a watch anymore, for one thing, unless out of affectation or nostalgia. And shoes? Well, rich people frequently pursue the shabby chic look while the impoverished seek to conspicuously display outward signs that they are not impoverished (I count myself among the latter, by the way…the shoes that I am now wearing I bought for ten bucks at a thrift store in Lincoln, Nebraska…these lovely suede buckskins are way above my pay grade, but you’d never know it.)
The literature of detection is inherently interesting because it hinges upon this fuzzy, slippery dimension of everyday life: that it is still possible to read the macro in the micro, to see in “the small individual moment the crystal of the total event.” This sort of thing relies upon the notion that there is a stable and coherent social order against which one can read a given particular clue. If, for instance, you lived in England during the Victorian age, you could pretty safely assume that someone sporting a tan had, in all likelihood been in the South at some point. Possibly India. Possibly in a military or civil/administrative capacity. So suddenly you know a fair amount about this stranger. There’s just no other way to obtain a tan. Callouses on your hands meant that you were a laborer.

The correct answer would be “it depends” or “compared to what”? After all, it’s not so much that everyone else in Eurasia stopped thinking 500 years ago, but rather than an explosion of knowledge occurred in Europe that rapidly outstripped other centers of civilization in Eurasia. And after a period of relative decline,
