Media thinking deals with the intersection of phenomenology, epistemology, and ontology. It examines the media-mediated appearance of all phenomena as well as the phantasmatic construction of epistemological formats and envisions an ethics of media solidarity in the sciences (mediarity). Media thinking investigates media events and contexts (mediamorphosis, immediality) as well as differences (alteraction, mediality). Phenomenologically, it is characterized by the media-mediated appearance of all phenomena. It utilizes the tension between epistemology and methodological skepticism to develop an epistemology and ontology that reflect on the phantasmatic conditions of their possibility, suggesting an absolute fragility of both the world and the subject. Against this backdrop, an ethics of media solidarity is proposed.
