This paper explores Carl Gustav Jung's groundbreaking contributions to psychiatry and psychotherapy, with a particular focus on his humanistic approach. Jung emphasized the profound influence of both the clinician's and patient's personal histories and personalities in therapeutic outcomes, propelling a shift from a “monopersonal” to a “bipersonal” perspective in therapy. He stressed the crucial role of the transference-countertransference dynamic, accentuating mutual influence within the clinician-patient relationship. Moreover, Jung's approach to psychotic symptoms as inherently meaningful and communicative, rather than simply concealment, opened new possibilities for psychotherapeutic treatment methods. This investigation illuminates Jung's substantial influence on the humanization of psychiatry, highlighting his unique creativity and originality in the clinical and theoretical landscape.
