No single text can create a public. Nor can a single voice, a single genre, or even a single medium. All are insufficient to create the kind of reflexivity that we call a public, since a public is understood to be an ongoing space of encounter for discourse. It is not texts themselves that create publics, but the concatenation of texts through time. Only when a previously existing discourse can be supposed, and a responding discourse be postulated, can a text address a public.
