After Lacan combines abundant case material with graceful yet sophisticated theoretical exposition in order to explore the clinical practice of Lacanian psychoanalysis. Focusing on the groundbreaking clinical treatment of psychosis that Gifric (Groupe Interdisciplinaire Freudien de Recherches et d'Interventions Cliniques et Culturelles) has pioneered in Quebec, the authors discuss how Lacanians theorize psychosis and how Gifric has come to treat it analytically. Chapters are devoted to the general concepts and key terms that constitute the touchstones of the early phase of analytic treatment, elaborating their interrelations and their clinical relevance. The second phase of analytic treatment is also discussed, introducing a new set of terms to understand transference and the ethical act of analysis in the subject's assumption of the Other's lack. The concluding chapters broaden discussion to include the key psychic structures that describe the organization of subjectivity and thereby dictate the terms of analysis: not just psychosis, but also perversion and obsessional and hysterical neurosis.
