Whoever pollutes the space with posters that carry sentences and images steals the surrounding landscape from everyone's view, kills their perception, and pierces the place through this very theft. First the landscape, then the world. He fills the space with black holes that suck in sensation and destroy the capacity for perception. By what right? He behaves like a universal squatter. In the same way, just as imperiously, a coin proves to be more visible, readable, and decipherable than the object it purchases. It seals the gaze upon it and kills that object. The symbol nullifies the thing. The world is expressed and erased by signs. Michel Serres writes about the inherent strategy of humans, derived from their kinship with animals, to appropriate something by taking it.
