If we learn racism by example, then literature plays an important part in the history of race in America, both negatively and positively. Morrison writes about nineteenth-century literary efforts to romance slavery, contrasting them with the scientific racism of Samuel Cartwright and the banal diaries of the plantation overseer and slaveholder Thomas Thistlewood. She looks at configurations of blackness, notions of racial purity, and the ways in which literature employs skin color to reveal character or drive narrative. Expanding the scope of her concern, she also addresses globalization and the mass movement of peoples in this century. National Book Award winner Ta-Nehisi Coates provides a foreword to Morrison’s most personal work of nonfiction to date.
