This book explores the relations among blackness, antiblackness, and Black people within the discourse of the blackness of black. This critical discourse developed during the last two decades as scholars explored what Saidiya Hartman describes as the afterlife of slavery. Hartman's concept, which argues for a troubling continuity between the status of enslaved and emancipated Black people, is the pivot between discursive tributaries and trajectories. Tributaries of the discourse of the blackness of black comprise five foundational concepts: Frantz Fanon's phobogenic blackness, Orlando Patterson's social death, Cedric Robinson's racial capitalism and the black radical tradition, and Hortense Spillers' flesh. The book traces three trajectories within the afterlife of slavery: Frank Wilderson's Afropessimism, Fred Moten's generative blackness, and Calvin Warren's black nihilism. This ensemble of concepts enable us to understand what is at state in how we understand the relations among blackness, antiblackness, and Black people.
