Kant, Marx, and the Money of Metaphysics

This paper discusses the relationship between Kantian idealism and Marxian materialism. Part I examines the reasons this relationship is misconstrued to be predominantly a matter of practical philosophy and turns to the neglected works of Alfred Sohn-Rethel and Richard Seaford to outline the importance of money for understanding Kant's theoretical work. Part II considers an objection that Kant confuses the commodity form for the transcendental object of experience. I am ultimately concerned with defusing the accusation that the identity of the commodity with a Kantian thing renders Kantian idealism "bourgeois" in the pejorative sense. Money is implicated, historically and conceptually, in the very intelligibility of metaphysics. In that case, Kantian idealism and Marxian materialism are two sides of the same coin.
