In her groundbreaking book Playing in the Dark: Whiteness and the Literary Imagination, Toni Morrison observed the opacity of experiences of whiteness as they are depicted in literature. When Marlow, the ferry captain in “Heart of Darkness,” travels deep into the Congo, he is stopped not by dark-skinned natives but by a white fog so thick that it blinds him. Morrison uses this image as tool to fathom the odd space that whiteness can inhabit in lived and literary spaces. Whiteness can seem to be a cultureless and silent nothing, a void that nonetheless exerts force as a central, normalizing vantage point. Yet whiteness is not nothing, and it is not normal: It is a space of unease, often policed and reinforced by the images of fear on its margins. In Notes from No Man’s Land, Eula Bliss tries to stand on the margins of her whiteness and to look in. In a series of dazzling and often soulful essays, she explains a life mapped in white and also not-white ways. She finds that her whiteness sometimes makes her feel trapped. She is less postracial than alert to contradictions in the way this whiteness functions and to the ambivalent privileges it affords her. Her essays travel multiple, not always parallel forms of history — personal and public trails that range from the history of telephone poles to coal mining towns to Laura Ingalls Wilder to public education. While her topics are heavy, she spins each essay gamely, with punning wit. The result: skeins that shimmer with metaphor, that pose and circle questions rather than trying to resolve them. “It isn’t easy to accept a slaveholder and an Indian killer as a grandfather, and it isn’t easy to accept the legacy a of whiteness as an identity,” she writes in an essay where she acknowledges that she can see “two faces of the Brooklyn clock tower” — and two faces of this question itself. “Perhaps it would be better if we simply refused to be white. But I don’t know what that means, really.” This may not be the answer, but the questioning opens doors to a new chapter of American self-understanding.
