Psychological wholeness stands as one of the most generative and contested concepts in the depth-psychology corpus. In its Jungian formulation, wholeness names the telos of individuation: the progressive integration of conscious and unconscious contents into what Jung called the Self, the master archetype that both orients and exceeds the ego. Murray Stein articulates the canonical position with precision — wholeness is ‘the master term that describes the goal of the individuation process.’ Yet the concept has never been received without friction. Hillman’s archetypal psychology mounts the most sustained challenge, arguing that the drive toward unity and integration betrays the psyche’s irreducible polycentrism; for Hillman, ‘elaboration, particularising, complication’ are preferable to integration, and the health of wholeness should not mean ‘the one dominating the many.’ Samuels identifies two distinct registers of the term — a psychological wholeness expressed through multiple relations and a theological wholeness expressed through approximation to an ideal unity — a distinction that clarifies much of the post-Jungian debate. Giegerich, characteristically, argues that striving toward wholeness in the conventional sense ‘acts out’ a psychological task rather than accomplishing it. Beyond the Jungian orbit, the concept appears in addiction literature as the primordial thirst underlying compulsion, in Buddhist-inflected psychotherapy as a ground already present rather than a goal to be achieved, and in Neumann’s ethical psychology as the transformation of negative contents within the whole personality. The term thus traverses soteriology, clinical practice, mythology, and metaphysics simultaneously.
