If we were able to take, as the finest allegory of simulation, the Borges tale where the cartographers of the Empire draw up a map so detailed that it ends up exactly covering the territory (but where, with the decline of the Empire this map becomes frayed and finally ruined, a few shreds still discernible in the deserts - the metaphysical beauty of this ruined abstraction, bearing witness to an imperial pride and rotting like a carcass, returning to the substance of the soil, rather as an aging double ends up being confused with the real thing), this fable would then have come full circle for us, and now has nothing but the discrete charm of second-order simulacra.
Abstraction today is no longer that of the map, the double, the mirror or the concept. Simulation is no longer that of a territory, a referential being or a substance. It is the generation by models of a real without origin or reality: a hyperreal. The territory no longer precedes the map, nor survives it. From now on, it is the map that precedes the territory - it is the map that engenders the territory and if we were to revive the fable today, it would be the territory whose shreds are slowly rotting across the map. It is the real, and not the map, whose vestiges subsist here and there, in the deserts which are no longer those of the empire, but our own. The desert of the real itself.
