THE TIME NONFICTION BOOK OF THE YEAR | #1 NEW YORK TIMES BESTSELLER"Powerful and timely ... I cannot recommend it strongly enough" - Barack ObamaBeyond race or class, our lives are defined by a powerful, unspoken system of divisions. In Caste, Pulitzer Prize-winning author Isabel Wilkerson provides a profound, eye-opening portrait of this hidden phenomenon. This is the story of how our world was shaped by caste, and how its rigid, arbitrary hierarchies still divide us today. Linking the caste systems of America, India, and Nazi Germany, Wilkerson explores eight pillars that underlie caste systems across civilizations, including divine will, bloodlines, stigma, and more. Using riveting stories about people--including Martin Luther King, Jr., baseball's Satchel Paige, a single father and his toddler son, Wilkerson herself, and many others--she shows the ways that the insidious undertow of caste is experienced every day. She documents how the Nazis studied the racial systems in America to plan their out-cast of the Jews; she discusses why the cruel logic of caste requires that there be a bottom rung for those in the middle to measure themselves against; she writes about the surprising health costs of caste, in depression and life expectancy, and the effects of this hierarchy on our culture and politics. Finally, she points forward to ways we can move beyond the artificial and destructive separations of human divisions, toward hope in our common humanity.
