Robert Morris’ sculptural installation “Hearing” includes an audio recording of a fictitious hearing that is focussed on the aesthetic, political, historical and moral views of a “witness”. The work is taken as a point of departure. Investigations relating to the various issues involved will take works of other artists into consideration. “Hearing” appears today as a piece of literature. Gregor Stemmrich edited and commented “Hearing” by Robert Morris in english for the first time.
