On our way home from the airport on the M-11, looking out from the passenger seat. Intervened, written, inhabited walls and noise barriers. There is an order in them. Graffiti: an ethics of walls. Ethics, for Foucault, refers to the type of relationship one has to oneself. In that sense, it is a practice, a style of life: a search for a certain “style of existence” (Rabinow 1997: xxxix). Graffiti on buildings, noise barriers, and walls along the highway. To look for a spot. To make some room for oneself: to put oneself next an other, alongside an other: adjacently: in front, behind, above, below, around. Never on top of an other: not going over: respect. An ethics of walls: a style of existence. Ethics, according to Foucault, can be understood as a way of relating, of creating sociality: modes of being together.
