The fifth volume of The History of Evil covers the twentieth century from 1900 through 1950. The period saw the maturation of intellectual movements such as Pragmatism and Phenomenology, and the full emergence of several new academic disciplines; all these provided novel intellectual tools that were used to shed light on a human capacity for evil that was becoming increasingly hard to ignore. An underlying theme of this volume is the effort to reconstruct an understanding of human nature after confidence in its intrinsic goodness and moral character had been shaken by world events. The chapters in this volume cover globally relevant topics such as education, propaganda, power, oppression, and genocide, and include perspectives on evil drawn from across the world. Theological and atheistic responses to evil are also examined in the volume.
