Book excerpt: Lacan, Language, and Philosophy explores the linguistic turn in psychoanalysis taken by Jacques Lacan. Russell Grigg provides lively and accessible readings of Lacan and Freud that are grounded in clinical experience and informed by a background in analytic philosophy. He addresses key issues in Lacanian psychoanalysis, from the clinical (how psychosis results from the foreclosure of the signifier the Name-of-the Father; the father as a symbolic function; the place of transference) to the philosophical (the logic of the "pas-tout"; the link between the superego and Kant's categorical imperative; a critique of Žižek's account of radical change). Grigg's expertise and knowledge of psychoanalysis produce a major contribution to contemporary philosophical and psychoanalytic debates.
