By “city life” I mean a form of social relations which I define as the being together of strangers. In the city persons and groups interact within spaces and institutions they all experience themselves as belonging to, but without those interactions dissolving into unity or commonness. City dwelling situates one’s own identity and activity in relation to a horizon of a vast variety of other activity, and the awareness that this unknown, unfamiliar activity affects the conditions of one’s own. [...] City dwellers are thus together, bound to one another, in what should be and sometimes is a single polity. Their being together entails some common problems and common interests, but they do not create a community of shared final ends, of mutual identification and reciprocity.
