Examines Deleuze's psychoanalytic and philosophical engagement with the Lacanian School.

Guillaume Collett questions to what extent we can locate Deleuze within the Lacanian School during the late-1960s, prior to Guattari. In so doing, he offers a new, integrated reading of Deleuze's The Logic of Sense (1969) by understanding it as a 'psychoanalysis of sense', and gives a new interpretation of Deleuze's conception of philosophy itself.

The Psychoanalysis of Sense shows that Deleuze was not merely aware of the debates animating the Lacanian School during the 1960s: he sought to contribute to them. Emphasising his appropriation of the work of post-Lacanian Serge Leclaire, Collett shows how Deleuze constructed a more singular and immanent theory of the linguistic structure of the unconscious – granting the erogenous body a larger structuring role.

• The first book devoted to situating Deleuze's 1960s work on psychoanalysis within the context of the Lacanian School
• Shows how Deleuze drew on Lewis Carroll and Sacher-Masoch to immanentise the work of the Lacanian School
• Develops a new reading of The Logic of Sense by viewing it as a meta-philosophical precursor to What is Philosophy?
