Jacques Lacan was one of the most important psychoanalysts ever to have lived. Building upon the work of Sigmund Freud, he sought to refine Freudian insights with the use of linguistics and mathematics, arguing that “the structure of unconscious is like a language”. He is widely misunderstood and often unfairly dismissed as impenetrable. In this clear, wide-ranging primer, Lionel Bailly demonstrates how Lacan’s ideas are still vitally relevant to contemporary issues of mental health treatment. Including coverage of developments in Lacanian psychoanalysis since his death, this is the perfect introduction to the great modern theorist.
