The republication of Suzanne de Brunhoff’s investigation into Karl Marx’s conception of “the money commodity” brings vital discussion to 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. <i>Marx on Money</i> is a well-written analysis of how money, credit, debt and value fit into the “logic of capital” that characterizes commodity society.
