This book is a key contribution to the debate about the nature of evil and a must-read for anyone making a serious study of responses to the holocaust. Arendt writes fluidly and you can polish the text off at quite a pace. It is not directly a work of philosophy, even in the sense that the rest of Arendt's work is, but a commentary on the key players in Eichmann's trial and the pertinent historical events, and mostly an analysis of the psychology of Eichmann. It is this psychological study which provokes the most important moral questions, as Eichmann is comes across as a rather stupid, ambitious individual who is sometimes comical in his failure but too complex to be a monster - in fact, too normal for comfort. This is the challenge posed by "the banality of evil": given the right environment and social factors, might there be an Eichmann in all of us? Be aware that Arendt has her own social and political axes to grind,and this comes through in her commentary on the trial.
