Through movement, we perceive space and at the same time we shape it. In walking, in thinking. By moving through them, says Michel de Certeau, we create spaces. In reflecting about the talking of steps trailing away, he presents the play of steps as the shaping of spaces. “Whereas in the active-passive commonsense model, time and space are located as stable signifiers into which the body enters, within a relational space and time are qualitatively transformed by the movement of the body. The body does not move into space and time, it creates space and time: there is no space and time before movement” (Manning 2007, xiii), so Erin Manning.
