This article turns to Hannah Arendt's Eichmann in Jerusalem in order to illustrate the difficulties involved in approaching the (formerly) metaphysical concept of evil as a secular phenomenon. It asks how the advocate of plurality, natality and forgiveness could also vouch for the death sentence of Eichmann based on a rhetoric of retribution and revenge. It then shows that Arendt's surprisingly consistent view of evil is based on a quasi-ontological understanding of the human condition that allowed her to negate Eichmann's (...) humanity. Rather than simply unmasking a metaphysical account in disguise, however, the article develops an alternative perspective that emerges from the conversation between Arendt and Jaspers. It argues that Jaspers's interpretation of Kant offers a way to defend the idea of secular evil and judge Eichmann on the basis of his thoughtlessness. (shrink)
