Within the depth-psychology corpus, ‘Art’ occupies a position far exceeding aesthetic theory: it functions as a primary vehicle of soul-making, healing, and psychological individuation. Thomas Moore, drawing on Ficino and the Jungian tradition, presents art as a discipline of embodied imagination through which ordinary life is rendered soulful — a surrender of rationality in exchange for depth. Shaun McNiff, the most prolific voice on the subject in these texts, argues that art’s healing power is archetype rather than profession, antedating modern therapy by millennia and defying monopolization by any clinical guild. McNiff insists that the question of what art actually is remains critically under-theorized within creative arts therapies themselves. Otto Rank situates art within a tripartite historical schema — primitive abstraction, classical harmony, Romantic dynamic conflict — linking each mode to a distinct psychological ideology. Iain McGilchrist reads the artistic impulse as originating in right-hemisphere faculty: gifts untaught, intuitive, resistant to left-hemisphere systematization. Across these writers a central tension persists: whether art heals by its formal and craft properties or by the relational, expressive field it opens. A secondary tension concerns access — whether art’s medicines belong to licensed professionals or to humanity at large. The stakes are simultaneously clinical, cultural, and ontological.
