In this volume, the author presents an enlightened theory of psychotherapy which has broad implications for the understanding of human behavior. His theory is distinctive in its emphasis on concepts that Freud developed in his late works concerning the patient's cognition and problem?solving activities to his power unconscious. The theory derives its clinical power from its empirical origin, closeness to observation, and from Weiss' cogent exposition of how to infer, from history and behavior, what the patient is trying to accomplish and how the therapist may help. Weiss develops the implications of his theory for technique and includes numerous clinical examples to illustrate concepts. This text is aimed at psychiatrists, psychologists, and clinicians in the field of mental health.
