Achille Mbembe’s Critique of Black Reason leaves larger questions unanswered, but points the way. It examines the changing use of ‘blackness’ as a category in an increasingly post-Western world order, and it raises the concept of ‘black reason’ as the thinking around the category that shapes its use. The book provides a history of the category in practice, its origins in the needs of capital, Atlantic then global diffusion, and moments of its change in practice: abolition, decolonization, and Apartheid. This drives the analysis to the crux of today, where the relation of West and the world is being reworked, enabling both new racism and a search for a ‘common world’ beyond black reason. Mbembe suggests ‘Europe’s twilight has arrived, and the Euro-American world has not yet figured out what it wants to know about, or to do with, the Black Man’ (p.7).
