Through a critical appropriation of Hannah Arendt, and a more sympathetic engagement with Theodor W. Adorno and psychoanalysis, this book develops a new theoretical approach to understanding Austrians’ repression of their collaboration with National Socialist Germany. Drawing on original, extensive archival research, from court documents on Nazi perpetrators to public controversies on theater plays and museums, the book exposes the defensive mechanisms Austrians have used to repress individual and collective political guilt, which led to their failure to work through their past. It exposes the damaging psychological and political consequences such failure has had and continues to have for Austrian democracy today—such as the continuing electoral growth of the right-wing populist Freedom Party in Austria, which highlights the timeliness of the book. However, the theoretical concepts and practical suggestions the book introduces to counteract the repression of individual and collective political guilt are relevant beyond the Austrian context. It shows us that only when individuals and nations live up to guilt are they in a position to take responsibility for past crimes, show solidarity with the victims of crimes, and prevent the emergence of new crimes. Combining theoretical insights with historical analysis, The Politics of Repressed Guilt is an important addition to critical scholarship that explores the pathological implications of guilt repression for democratic political life.
