We discuss Part IV: "The Triumph and Death of Western Marxism" with particular focus on the work of Hannah Arendt in The Origins of Totalitarianism and On Revolution. We discuss Losurdo's analysis of "recognition" from Hegel and how revolution is theorized as recognition in Marx and Engels and how subsequent liberal theories of revolution in Arendt and Nietzschean theories of Foucault promote what Losurdo sees as the "death" of Western Marxism.
