This article offers a close reading of Hannah Arendt’s Eichmann in Jerusalem: A Report on the Banality of Evil. It argues that in this text, Arendt consistently, even obsessively, evaluates the legal and moral challenges posed by Eichmann’s trial through the relationship between exception and rule. The article contends that the analytical lens of the exception allows us to appreciate the perplexities that Eichmann in Jerusalem presents – some fifty years after the book’s publication – from a still uncommon perspective, and enables us to attend in new ways to Arendt’s own suppositions, propositions, and contradictions in this text.
