The term ‘World’ occupies one of the most contested and generative positions in the depth-psychology corpus, functioning simultaneously as cosmological structure, phenomenological ground, psychological container, and spiritual adversary. No single valence prevails. Plato’s Timaeus establishes the archetype of the World-Soul — a rational, self-moving, spherical cosmos animated by divine Reason — which reverberates through Stoic physics (the world as divine animal suffused by world-heat and pneuma), Neoplatonism, and ultimately into Renaissance and depth-psychological conceptions of anima mundi. Against this participatory cosmology stands the Gnostic counter-tradition identified by Hans Jonas: here the World is the alien domain, the prison of light, the inn in which the soul lodges as a stranger. Heidegger’s phenomenological analysis introduces yet another register, distinguishing the ontical totality of entities from ‘worldhood’ as an existential structure of Dasein’s Being-in. Tarnas extends this into cultural diagnosis: the modern world view enforces a radical subject-object split absent from primal cosmologies. Hillman and Sardello, working in the Jungian-archetypal lineage, press toward reanimation of the world through the anima mundi — insisting that soul inheres in things, not merely in persons. The tensions that most energize this cluster are: immanence versus transcendence, participation versus alienation, and the world as psychological fact versus the world as mere material substrate.
