This volume of specially commissioned essays is a critical introduction to the psychology of Carl Jung, one of the founders of psychoanalysis. Jung broke with Freud and developed his own theories which he called 'analytical psychology'. The fifteen essays set Jung in the context of his own time, outline the current practice and theory of Jungian psychology and show how Jungians continue to question and evolve his thinking and apply it to aspects of modern culture and psychoanalysis. Andrew Samuels's introduction gives an appreciation of Jung's work and discusses the three approaches to analytical psychology. The Companion includes a full chronology of his life and work, reading lists, a case study and a glossary. It is an indispensible reference tool for both students and specialists, written by an international team of Jungian analysts and scholars from various disciplines.
