Diane Jeske's penetrating study of evil is the philosophical equivalent of an action-packed thriller. Few theoretical contributions are so riveting, so engrossing, so seductive that they cannot be put down. Jeske's book is that rare exception. Through vivid case studies that range from Nazis to American presidents, from slave owners to serial killers, Jeske delves into the moral dimensions of evil, the psychological devices that enable it to flourish, the grounds
upon which it is legitimately excused, and the conditions under which even the best of us might succumb to its temptations. Her new philosophical moves invigorate old moral debates and her use of the tragic choices and compromised commitments of famous people reveal how frighteningly thin the line can
be between good and evil. Jeske's book is a haunting reminder that living on the right side of that line requires not just moral knowledge but vigilant stewardship of one's character.
