The psychoanalytic field theory is one of the most vibrant and original currents of contemporary psychoanalysis. By reinterpreting concepts such as dreams and the unconscious, it contributes to establishing a new paradigm in analytically grounded psychotherapy: the unconscious is no longer seen as a region of the psyche, but as an intersubjective function of personality that gives meaning to emotional experience. The psychotherapeutic treatment focuses on the level of unconscious communication shared by the psychotherapist and the patient, transcending the I/You separation to access the We of the shared substance of the psyche. Giuseppe Civitarese provides a comprehensive introduction to the most significant concepts of psychoanalytic field theory. Through numerous clinical examples, he explores the central theme of therapeutic effectiveness, reflects on current controversies, and clarifies that the psychotherapeutic process is radically intersubjective.
