The book "Love, Guilt and Reparation" presents the development of Melanie Klein's work and ideas between 1921 and 1945. Her earlier works reveal her intense focus on the impact of childhood anxieties on child development. She tracks these influences in criminality and childhood psychosis, the process of symbolization and mental inhibition, as well as the early development of conscience. In her later work on the Oedipus complex, Klein develops her theories on the early developmental phases of the infant, extending Freud's analysis of the Oedipus complex and establishing her concept of the paranoid-schizoid position during the first six months of life. The volume also includes a foreword by Dr. Hanna Segal and explanatory notes by the Editorial Board of the Melanie Klein Trust.
