This book is a thought-provoking exploration of the trial of Adolf Eichmann, a major organizer of the Holocaust. The author argues that Eichmann was not a fanatical ideologue, but rather an ordinary individual who simply followed orders and bureaucratic procedures, highlighting the terrifying potential for evil in any system that values obedience over personal responsibility. The concept of the "banality of evil" is introduced, suggesting that horrific acts can be committed by ordinary people under certain conditions.
