Few thinkers have illuminated the history of the 20th century with the same intensity, always accompanied by critics and supporters, as the political thinker Hannah Arendt. In this volume, philosophers, sociologists, and political scientists critically examine the work and political activities of Hannah Arendt, opening up partially unprocessed perspectives and revealing research desiderata. The contributions present a varied and sometimes critical image of Hannah Arendt. Throughout, there is a palpable fruitful irritation stemming from the questions posed by Hannah Arendt, which evidently remain relevant today. Especially in the criticism, the political relevance of Hannah Arendt becomes clearly evident.
