Circulation is a central dimension of contemporary global processes, involving the velocity, scale, and form of movement of ideas, persons, commodities, and images, in ways that disturb virtually all existing cartographies of culture, place, and identity. In the structural transformation of the Public Sphere, Habermas argues that changing ideas of publicness and public opinion that are crucial for the development of new forms of political subjectivity first develop in the literary public sphere and its "institutionalization of privateness oriented to an audience". Forms such as quotation, direct and indirect discourse, and free indirect style also distinguish between the so-called reporting event, and the source or reported speech event, and it is these very forms that make up the repertoire of narrative devices and are also at the heart of Bakhtin's metalinguistics. The circulating objects are the tools for the construction of new images, worldviews, and ideologies, whether it is the 'imagined communities' of nationalism or transnational diasporas.
