"Their swarming mass is an innumerable collection of singularities. Their intertwined paths give their shape to spaces. They weave places together. In that respect, pedestrian movements form on of those realsystems whose existence in fact makes up the city. They are not localized; it is rather they that spatialize. They are no more inserted within a container than those Chinesecharacters speakers sketch out on their hands with their fingertips."
Michel de Certeau, "Walking in the City," The Practice of Everyday Life, trans. Steven Rendall, Berkeley, Los Angeles, London: University of California Press, 1984.
