Book excerpt: The republication of Suzanne de Brunhoff’s classic investigation into Karl Marx’s conception of “the money commodity” shines light on commodities and their fetishism. The investigation of money as the crystallization of value in its material sense is central to how we understand capitalism and how it can be abolished. Marx on Money is an elegant analysis of how money, credit, debt and value fit into the “logic of capital” that characterizes commodity society.
