In his fine treatment of Jacques Derrida: Live Theory , James K.A. Smith assesses Derrida’s debt to Marx. Despite owing a real debt, Smith notes that there is “a fundamental logic of dissociation at work in Derrida’s ‘spirit of Marxism’ whereby he distances himself from the doctrines and dogmatics of a Marxist ontotheology and ‘the Party.’” As he seeks the religious without the specifics of particular religions, so he seeks a “purely ‘formal’ Marxism without Marxism.”
Which raises two responses in my mind: First, Derrida is post -structuralist? And, here as elsewhere Derrida sounds Plato-haunted.
