The aim of this paper is to throw new light on a previously neglected aspect of Hayek’s political theory. In order to show the significance of Hayek’s evolutionary argument, the paper draws on Foucault’s thesis about the relationship between political order, life and war. Focusing on Hayek’s conception of the open society and, in particular, on the evolutionary ontology that grounds it, the paper shows how his liberalism reflects the problematic that Foucault began to elucidate in his 1976 lecture course Society must be defended. The paper concludes by showing how the biopolitical dimension of Hayek’s liberalism might affect our understanding of his political project. Copyright © 2013 Taylor and Francis.
