This study examines the Enlightenment as a communicative process, drawing on the example of Osnabrück Enlightenment thinker Justus Möser (1790–94). It analyzes social and media-specific entanglements in connections with discourses about practical enlightenment projects. The focus on cross-media processes and the consideration of Möser’s double role as a statesman and Enlightenment thinker provide new insights into the German Enlightenment.
