In the early 1950s her archival papers and diary entries display deep concern for a host of topics at the intersection of political and economic thought: labor, work, slavery, consumption, industrialization, and automation. This article provides a genealogy of Hannah Arendt’s treatment of political economy in the years prior to the publication of The Human Condition (1958). This article thus illuminates new dimensions of the totalitarianism debate in American political thought and provides a fuller picture of Mailer's significance as a social critic. Mailer's focus on the United States was symptomatic of a broader intellectual trend towards the study of non-statist forms of totalitarianism which has yet to receive adequate scholarly attention. His theory of cultural totalitarianism focused on internal psychological manipulation rather than external political coercion. Mailer's crucial intervention offered an alternative theory which viewed totalitarianism as an internal threat to the United States and de-emphasized the centrality of the state. Dominant understandings of totalitarianism from the 1930s to the 1950s focused on external threats and were wedded to notions of pervasive state control of all aspects of life. This article investigates Norman Mailer's appropriation and Americanization of the concept of totalitarianism as an internal critique of US society and culture in the 1960s. In conclusion, this striking affinity with Marxism in Arendt's early work is contrasted with the emergence of classical totalitarianism theory-a project with which Arendt was soon eager to associate herself and which makes a unified and consistent reading of The Origins of Totalitarianism so difficult. Third, it shows that Arendt wrote in these languages and contributed to the same debate. Second, it shows how these languages underpinned a central controversy in Marxist theories of totalitarianism during World War II, a debate conducted in the languages of imperialism and Bonapartism and turning on the relationship between the political and the economic. First, it reconstructs two core languages of interwar Marxism (imperialism and Bonapartism). Building on a novel genealogy of Marxist theories of totalitarianism, the article traces this inheritance into Arendt's early work on the subject, demonstrating that her “languages” (in the Pocockian sense) were basically continuous with those of interwar Marxism. This article offers a new reading of the place of Hannah Arendt's The Origins of Totalitarianism in the history of totalitarianism theory.
