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.
