Book excerpt: Lacan Contra Foucault seeks to ground the divergences and confluences between these two key thinkers in relation to contemporary philosophy and criticism. Specifically the topics of sexuality, the theory of the subject, history and historicism, scientific formalization, and ultimately politics. In doing so, the authors in this volume open up new connections between Lacan and Foucault and shine a light on their contemporary relevance to politics and critical theory.
