Book excerpt: An enligtening and powerful exploration of those who risked their lives to help others during the Holocaust—and those who did not—and what we must do to ensure that such a tragedy never occurs again. Why, during the Holocaust, did some ordinary people risk their lives and the lives of their families to help others—even total strangers—while others stood passively by? Samuel Oliner, a Holocaust survivor who has interviewed more than seven hundred European rescuers and nonrescuers, provides some surprising answers in this compelling work. Samuel Oliver delves into the profound acts of altruism that emerged during one of history's darkest periods. Each interview provides a unique insight into the types of personalities that answer a call to action, and those that do not. By comparing these rescuers with bystanders, he provides a nuanced understanding of what drives people to act with extraordinary compassion—or to remain passive in the face of evil. Offering both a historical perspective and a roadmap for a more compassionate future, Altruistic Personality is not just a historical account—it is a call to action and a beacon for moral education. Relevant when it was first published and even more relevant today, Oliver argues that by understanding and fostering the traits of altruism, we can prevent future atrocities and bring out the better aspects of humanity.
