This essay examines the effects of the critique of religion on the critique of capital and how the former confines the latter. It asks: What remains of the concepts of alienation or fetishism if they all stem from an anthropology of religion that seems to be criticized? If religion ceases to refer to an anthropological essence and is criticized as a European colonial concept, then what happens to the critique of capital? It argues that what Marx considers the condition for critique seems to be the blind spot of Western Marxism. Without a critical analysis of how the concept of religion is constructed and how religion is thus described as a human invention, Marxism cannot know itself. If Marx is a “critic of the critique of religion,” this gesture must apply to Marx as well as to Marxism itself. The critique of capitalism might need an alternative foundation if the anthropological concept of religion that supported it collapses. It is therefore impossible to maintain the critique of capital as it is while refusing the critique of religion that lies at its foundation.
