This book collects rewritten articles and essays by the author related first and foremost, but not exclusively, to the catastrophe of the Holocaust as an epistemic crisis – qualified as a “rupture in civilization”, i.e. the destruction of concepts deeply rooted in a common anthropology of humankind, while focusing on methodological as well as conceptual questions. The composition of the volume runs roughly chronologically along several layers of interpretation – embracing questions of German constitutional law, the formation of Continental expansionist geopolitical thinking, the epistemology of the Holocaust, the assertion and transformation of paradigms of historical interpretation in the second half of the 20th century, especially the turn from social history to memory studies, as well as the turn from a Western- and Eurocentric approaches into the direction of colonial and global history.
