This book explores how modern religious thought and religious Zionism have addressed the profound question of evil, with a particular focus on the Holocaust. It delves into the theological and philosophical challenges posed by absolute, undeniable, and inexplicable primal evil. The awareness of this primal evil serves as the foundation connecting the chapters, which trace the perspectives of influential thinkers such as Rabbis Zvi Yehuda Kook, Yosef Dov Soloveitchik, and Eliezer Berkowitz, as well as figures like Rabbi David Hartman and Eliezer Goldman.

Through a combination of philosophical and theological inquiry alongside historical and conceptual analysis, the book creates a rich mosaic of religious thought in the modern era. It also examines the responses of leaders and activists to the enduring question of evil in the shadow of Auschwitz.
