"Modern literary theory sees a similarity between walking and writing that I find persuasive: words inscribe a text in the same way that a walk inscribes space. In The practicse of Everyday Life, Michel de Certeau writes, 'The act of walking is a process of appropriation of the topographical system on the part of the pedestrian; it is a special acting-out of the place...and it implies relations among differentiated positions.' I think this is a fancy way of saying that writing is one way of making the world our own, and that walking is another."
