This new edition of Roger Money-Kyrle s classic work is published together with three of his late papers, "Cognitive development," "The aim of psychoanalysis," and "On being a psychoanalyst." Its intention is to introduce new readers to this key Kleinian thinker, whose influence has been quiet and uncontroversial but deep and formative. The book also includes Donald Meltzer s discussion of the paper on "Cognitive development.""
