Michel De Certeau said this quote

Finally, the functionalist organization, by privileging progress (i.e. time), causes the condition of its own possibility--space itself--to be forgotten: space thus becomes the blind spot in a scientific and political technology. This is the way in which the Concept-city functions: a place of transformations and appropriations, the object of various kinds of interference but also a subject that is constantly enriched by new attributes, it is simultaneously the machinery and the hero of modernity.

~ Michel De Certeau

Reading thus introduces an art which is anything but passive.

~ Michel De Certeau

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.

~ Michel De Certeau

To practice space is thus to repeat the joyful and silent experience of childhood; it is, in a place, to be other and to move toward the other...Kandinsky dreamed of: 'a great city built according to all the rules of architecture and then suddenly shaken by a force that defies all calculation.

~ Michel De Certeau
