Isabel Wilkerson is an American journalist and the first woman of African American heritage to win the Pulitzer Prize in Journalism. Her most recent book—Caste: The Origins of our Discontents—explores, through layered analysis and stories of real people, the structure of an unspoken system of human ranking and reveals how our lives are still restricted by what divided us centuries ago. Caste uses a comparative lens—the treatment of Untouchables in India, Jews in Nazi Germany, and African-Americans in the US—to shed new light on dehumanization…its causes, consequences, and potential remedies.
