Cedric Robinson's increasingly popular and influential work Black Marxism is best understood as a project of post-Marxist critique. Robinson's book, now regarded as a classic, asks a series of important questions of Marxism, but each of its major arguments marks a fundamental departure from the theoretical perspectives of both European and Black Marxists. The book exists in a historical moment of crisis for the left and intellectual retreat from Marxism; Robinson's relationship with Marxism and his place in the political tradition to which he gave a name, the Black Radical Tradition, suggests three main arguments. First, Robinson's critiques of the classical Marxist tradition — focused on its apparent economism and Eurocentrism — are based on a flattening of this tradition and a marked break from Marxist methodology. Second, Robinson's critique does not neatly align with the perspectives of the radical Black intellectuals whom he discusses, and indeed his conclusions are frequently in conflict with them. Third, the emancipatory project of Black Studies and the research programs convened under Robinson's influence will be best served by cautious and critical engagements with Robinson's seminal work. The generative questions that Robinson asks will be better answered through a materialist account of Black history, a syncretic understanding of Black culture, and a nonreductive, revolutionary Marxism providing the guide for political action.
