This book focuses on adolescence and adolescent states of mind. It is one of a series that record Donald Meltzer's clinical seminars and supervisions, which were conducted in various countries on a regular basis over many years. Despite his interest in the theoretical advances of psychoanalysis made during what he termed The Kleinian Development, Meltzer believed that clinical supervision was the only way to teach psychoanalytic practice. In effect he treated supervision as an art form just as he regarded psychoanalysis as an art form. The library of his supervision work, almost all recorded outside the UK, thus forms a valuable teaching model for future practitioners, as well as demonstrating Meltzer's wealth of insight into both character development and analytic technique.
