Elie Wiesel --- a Nobel laureate, activist, adviser to world leaders, and the author of more than 40 books --- taught at Boston University for nearly four decades. With this book, Ariel Burger --- devoted protégé, apprentice and friend --- takes us into the sacred space of Wiesel’s classroom. There, Wiesel challenged his students to explore moral complexity and to resist the dangerous lure of absolutes. In bringing together never-before-recounted moments between Wiesel and his students, WITNESS serves as a moral education in and of itself --- a primer on educating against indifference, on the urgency of memory and individual responsibility, and on the role of literature, music and art in making the world a more compassionate place.
