Hannah Arendt, German Jewish philosopher who emigrated to the United States, attended the trial of Adolf Eichmann (responsible for deportations under Nazi Germany) in Israel and proposes the concept of "the banality of evil" to describe mass destruction and "bureaucratic" Jews in the countries occupied by the Nazis. Diving in mind (rather empty ...) a great criminal, the book is also a story of the destruction of European Jewry. Controversy and rich the book gives to meditate.
