Ian Hacking has argued that the book Leviathan and the Air-Pump acted as a historiographical source in his analysis of the laboratory style of thinking and doing. The present article analyzes Hacking’s appropriation of Shapin and Schaffer’s work as a rewriting of the history of English experimental philosophy of the seventeenth century. The analysis focuses on the contingency/permanence tension with the aim of investigating the two historiographic narratives as attempts to overcome what Bernstein calls “Cartesian anxiety.” First, I examine the mundane historiography of Shapin and Schaffer and their philosophical commitment to finitism as constitutive of their historiographical approach. Second, I analyze Hacking’s appropriation of Fernand Braudel’s historiography in writing a material history of experimental philosophy. Finally, I address the notion of form of life as a nuclear point in the ways that Hacking and Shapin and Schaffer seek to move beyond Cartesian anxiety.
