This book aims to provide a synthesis of the knowledge about the origins of sexual animosity between men and women within a societal context. The book aims to represent a variety of views and is intended to be of interest to practitioners in the fields of marital therapy and psychoanalytic psychotherapy. The central thesis of the book is that sexual animosity is retrenched aggression manifested in narcissistic values and behaviour. The book aims to allow for therapeutic strategy to evolve and those who are interested in analytic theory will find source material which will be useful for further theoretical considerations on narcissism and aggression.
