A sweeping exploration of religion and the history of human violence—from the New York Times bestselling author of The History of God • “Elegant and powerful.... Both erudite and accurate, dazzling in its breadth of knowledge and historical detail.” —The Washington Post In these times of rising geopolitical chaos, the need for mutual understanding between cultures has never been more urgent. Religious differences are seen as fuel for violence and warfare. In these pages, one of our greatest writers on religion, Karen Armstrong, amasses a sweeping history of humankind to explore the perceived connection between war and the world’s great creeds—and to issue a passionate defense of the peaceful nature of faith.   With unprecedented scope, Armstrong looks at the whole history of each tradition—not only Christianity and Islam, but also Buddhism, Hinduism, Confucianism, Daoism, and Judaism. Religions, in their earliest days, endowed every aspect of life with meaning, and warfare became bound up with observances of the sacred. Modernity has ushered in an epoch of spectacular violence, although, as Armstrong shows, little of it can be ascribed directly to religion. Nevertheless, she shows us how and in what measure religions came to absorb modern belligerence—and what hope there might be for peace among believers of different faiths in our time.
