The Knowledge of the Psychoanalyst documents Raul Moncayo’s practice of analysis over a period of twenty-five years.Exploring different aspects of knowledge in the work of Freud and Lacan, Moncayo considers themes including not-knowing as opposed to non-knowing, truth, and ignorance. The book considers unconscious guilt, S1 signifiers, understandings of history as both linear and circular, and the different levels of mind in Mahayana Buddhism and psychoanalysis. The book also presents cases of obsessional neurosis and hysteria in the Lacanian sense. The book concludes with Moncayo’s own interpretation of Lacan’s theory, in the same way that Lacan had his own interpretation of Freud.The Knowledge of the Psychoanalyst will be of great interest to Lacanian analysts in practice and in training, and academics and scholars of Lacanian theory.
