In 1755 the city of Lisbon was destroyed by a terrible earthquake. Almost 250 years later, an earthquake beneath the Indian Ocean unleashed a tsunami whose devastating effects were felt over a vast area. In each case, a natural catastrophe came to be interpreted as a consequence of human evil. Between these two events, two indisputably moral catastrophes occurred: Auschwitz and the bombing of Hiroshima and Nagasaki. And yet the nuclear holocaust survivors likened the horror they had suffered to a natural disaster--a tsunami. Jean-Pierre Dupuy asks whether, from Lisbon to Sumatra, mankind has really learned nothing about evil. When moral crimes are unbearably great, he argues, our ability to judge evil is gravely impaired, and the temptation to regard human atrocity as an attack on the natural order of the world becomes irresistible.

Jean-Pierre Dupuy is Professor of Social and Political Philosophy at the École Polytechnique, Paris.
