"Why?" This is the question I'm often left with after reading about Holocaust rescuers. They often seem far above ordinary humans, out of the sphere of people like me - but not in this book. The Heart Has Reasons shows rescuers in the context of their lives, as people who have learned to perceive, evaluate, and think for themselves. In the words of one of them, they do "not accept oversimplified answers". Their cultural and life histories helped them see everyone as equally human with themselves. Their answers, direct or indirect, to the question of why they helped the Jews invariably return to these ideas and often describe a journey of very small beginnings. In demystifying these Dutch rescuers, Klempner in no way diminishes them or their achievements. Indeed, their nobility is increased, as they become realistic examples of what ordinary people can do to change history. In letting the rescuers tell their own stories, interspersed with historical perspective and philosophical and personal commentary, Klempner effectively shows us the traits we must nurture in all children. A true storyteller, he lets his subject dictate its form. As we get to know the rescuers, we start with the usual question and end up each time with, perhaps, the only answer that can prevent other Holocausts.
