Betty Joseph's work has become an outstanding influence in the development and theory of psychoanalytic technique in the Kleinian tradition. This collection of her most important papers examines the development of her thought and shows why a crucial part of her theory and practice is concerned with the detailed, sensitive scrutiny of the therapeutic process itself. Fundamental and controversial topics explored and discussed include projective identification, transference and countertransference, unconscious phantasy, and Kleinian views on envy and the death instinct.
