Few philosophers and social scientists of the 20th century are likely to have had an intellectual influence on the debates in science and the public as much as Hannah Arendt. At the same time, only a few were so controversial, only a few were so polarized and only a few saw themselves exposed to such intense hostility as they did. A number of their theses and considerations met with energetic opposition and triggered downright hateful debates, some of which are still carried on today. Hannah Arendt is rightly regarded as a stimulating thinker - who will possibly continue to have an effect in the future, especially through her problems. In this volume, philosophers, political scientists, sociologists and historians take up Hannah Arendt's ideas, problems and considerations and continue them critically.
