His works have been dubbed "Trümmerliteratur" (the literature of the rubble). He was a leader of the German writers who tried to come to grips with the memory of World War II, the Nazis, and the Holocaust and the guilt that came with them. Because of his refusal to avoid writing about the complexities and problems of the past he was labelled by some with the role of 'Gewissen der Nation' (conscience of the nation), in other words a catalyst and conduit for memorialisation and discussion in opposition to the tendency towards silence and taboo. This was a label that he himself was keen to jettison because he felt that it occluded a fair audit of those institutions which were truly responsible for what had happened.
