As is evident in this volume of her clinical and theoretical papers, Hanna Segal has established herself as one of the most productive and sensitive clinical psychoanalysts in the field today. Using techniques based on the work of both Freud and Klein, she has shown a consistent interest in working with patients presenting the most severe types of psychopathology. Her techniques stress the analytic and insightful resolution of these disturbances rather than avoidance based on anxiety in the therapist.
