The concept of ‘political energy’ is often treated as merely a rhetorical synonym for enthusiasm and active engagement. However, as Bruce Clarke’s Energy Forms argues there is an allegorical traffic of ideas between politics and science that reaches an apotheosis in the early-twentieth century interest in energy. In the field of the ‘energy-humanities’ inaugurated by Clarke, the work of George Sorel remains largely overlooked. Situating itself in this field, my paper investigates the interplay of science and politics in Sorel’s work. (...) I contend that Sorel, influenced by Vico’s ideogeneitic law anticipates Clarke’s allegorical framework. Paralleling Henri Bergson’s attempts to rethink the novelty of life in the post-thermodynamic framework of energy, I argue that models from science (Brownian motion and friction) underlie Sorel’s conceptions of political myth and class antagonism. While these remain inchoate in Sorel’s works, I conclude with the suggestion that these traces are completed in Ernst Jünger’s conception of ‘total mobilization’. (shrink)
