Professor of media theories Wolfgang Ernst (Humboldt University) opened his presentation by stating that the subject of this workshop, ‘experimentality as event’, touches a crucial figure of contemporary epistemology, especially when we take epistemology in its processual, time-based meaning as defines by cybernetics which is – taken by its original self-definition – the insight into ‘Circular Causal and Feedback Mechanisms’ (Heinz von Foerster, 1949). Consequently, Ernst proposed that we investigate the processuality and eventuality of media-enhanced experimentation.
