They become liberated spaces that can be occupied. A rich indetermination gives them, by means of a semantic rarefaction, the function of articulating a second, poetic geography on top of the geography of the literal, forbidden or permitted meaning. They insinuate other routes into the functionalist and historical order of movement. Walking follows them: 'I fill this great empty space with a beautiful name.'
Michel de CerteauThe panorama-city is a 'theoretical' (that is, visual) simulacrum, in short a picture, whose condition of possibility is an oblivion and a misunderstanding of practices.
Michel de CerteauThe sick man must follow his illness to the place where it is treated... He is set aside in one of the technical and secret zones (hospitals, prisons, refuse dumps) which relieve the living of everything that might hinder the chain of production and consumption, and which repair and select what can be sent back up to the surface of progress.
Michel de CerteauThe sick man is taken away by the institution that takes charge not of the individual, but of his illness, an isolated object transformed or eliminated by technicians devoted to the defense of health the way others are attached to the defense of law and order or tidiness.
Michel de CerteauFirst, if it is true that a spatial order organizes an ensemble of possibilities (e.g., by a place in which one can move) and interdictions (e.g., by a wall that prevents one from going further), than the walked actualizes some of these possibilities. In that way, he makes them exist as well as emerge. But he also moves them about and he invents others, since the crossing, drifting away, or improvisation of walking privilege, transform, or abandon spatial elements.
