To walk is to lack a place. It is the indefinite process of being absent and in search of a proper. The moving about that the city mutliplies and concentrates makes the city itself an immense social experience of lacking a place -- an experience that is, to be sure, broken up into countless tiny deportations (displacements and walks), compensated for by the relationships and intersections of these exoduses that intertwine and create an urban fabric, and placed under the sign of what ought to be, ultimately, the place but is only a name, the City...a universe of rented spaces haunted by a nowhere or by dreamed-of places.
The long poem of walking manipulates spatial organizations, no matter how panoptic they may be: it is neither foreign to them (it can take place only within them) nor in conformity with them (it does not receive its identity from them). It creates shadows and ambiguities within them. It inserts its multitudinous references and citations into them (social models, cultural mores, personal factors). Within them it is itself the effect of successive encounters and occasions that constantly alter it and make it the other's blazon: in other words, it is like a peddler carrying something surprising, transverse or attractive compared with the usual choice. These diverse aspects provide the basis of a rhetoric. They can even be said to define it.
