Melanie Klein was an innovative, highly controversial and influential psychoanalytic thinker. She was a follower of Freud but her theories diverged from his in significant ways. She built significantly on Freud's ideas and also on the ideas of Karl Abraham, Sandor Ferenczi, Ronald Fairbarn and many others. Her work with children opened up new ways of thinking and new avenues for investigation, and these avenues continue to be explored today. These lectures outline some of Klein's main ideas, many of which caused an outcry at the time, some of which remain controversial and others of which are now part of mainstream thinking. These will also give you a sense of the ways in which Klein's thought influences practice and thinking today.
