This article shows that the methodology of Mills’ ‘Black Radical Kantianism’ (BRK) represents a major plot twist for Kant studies as well as contemporary political philosophy utilizing Kantian ideas. BRK is no mere upgrade of Kant’s or Kantian ideal theory for racial justice. Mills’ methodology requires us to posit both that the real Kant and establishment Kantianism have been racist, sexist and Eurocentric; and that only by first admitting and reckoning with the compatibility of white supremacy and liberal egalitarianism can we hope to radicalize Kant or Kantianism.
