In The Letter in Black Radical Thought, Tendayi Sithole unmasks the logics of dehumanization in the terrain of black radical thought by looking at the letter as the site of examination and political intervention. Through his expansive demonstration and original argument, he analyzes the letters of Sylvia Wynter, Assata Shakur, George Jackson, Aìme Césaire, and Frantz Fanon. Through a close reading, and thus illuminating critical takes by these black radical thinkers, Sithole orchestrates a thematic approach, revealing the challenges to dehumanization which emerge in these letters. All the afore-mentioned figures are read anew through the typology of the letters they have penned. This typology consists of epistemic, fugitive, intramural, and resignation letters. The Letter in Black Radical Thought shows how these letters confront and combat dehumanization in novel ways.
