The task Dr. Otto Kernberg takes up in The Inseparable Nature of Love and Aggression: Clinical and Theoretical Perspectives is to first distinguish, then to interrelate psychoanalytic, clinical psychiatric, and neurobiological perspectives in a variety of areas, beginning with severe personality disorders and extending to love, destructiveness, mourning, spirituality, and the future of psychoanalytic inquiry. Dr. Kernberg is renowned for his work with borderline and narcissistic patients, and in this book, he offers new approaches to the diagnosis and treatment of the most severe personality disorders, particularly the spectrum of severe narcissistic psychopathology. His effort to relate psychoanalytic to neurobiological findings continues in two fascinating areas the study of sexual love and of religious experience and he examines object relations theory in relation to these two phenomena. Kernberg s analysis of love and aggression is both bold and nuanced and will captivate the professional psychotherapist as well as the psychologically astute general reader.
