This article offers an anthropological reading of the works of Immanuel Kant and Kwame Nkrumah. By doing so it seeks to expose the Eurocentric and racist ontology that lies behind dominant contemporary forms of cosmopolitanism. The article draws attention to the possibility of a more egalitarian vision of the world as one that can be derived from the perspective of an African philosophical viewpoint. Rather than regarding African social theory as a subordinate or subaltern mode of apprehending the world, it places African philosophy on a par with European traditions of philosophical thought. By focusing on some of the central tenets of cosmopolitanism, it argues that Nkrumah, by insisting on freedom and equality for all of humanity, had articulated a more genuinely cosmopolitan ontology than any that can be derived from the philosophy of Kant. The article argues that an engagement with critical anthropology enables us to imagine forms of decolonised cosmopolitanism which are genuinely both inclusive and egalitarian.
