When Derrida finally came to write at length about Marxism, it was to be in terms not of a recent engagement, but of hauntings from the past.¹ Derrida's text is haunted by Marx, just as Marx's texts, especially The German Ideology, are haunted by Max Stirner, whose own texts, Derrida tells us, are haunted by Hegel's, especially The Phenomenology of Spirit.² The ancestral spectres go back, we may assume, ad infinitum.
