Paradise occupies a structurally complex position within the depth-psychological corpus, functioning simultaneously as cosmological locus, alchemical metaphor, archetypal image, and psychological diagnosis. Jung treats it most systematically in his alchemical writings, where it figures as a symbol of the albedo — the restored state of innocence — and as a quaternary structure anchored by four rivers whose fourfold nature aligns it with the quaternio schemas central to his late psychology. Von Franz introduces a crucial critical valence: the paradise ideal, when approached regressively, becomes what she calls a ‘neurotic utopia,’ a childish longing to return to the womb that forestalls genuine individuation. This tension — between paradise as genuine telos and paradise as regressive fantasy — is the engine of the term’s psychological ambiguity. Mythologists such as Campbell locate paradise at the intersection of geographical imagination and sacred narrative, tracing how Columbus projected the four rivers of Genesis onto the Orinoco. Miller traces the fate of paradise’s rivers as they descend through Platonic, Jewish apocalyptic, and Dantean tradition into increasingly darkened symbolic registers. Theological sources — John of Damascus, the Philokalia, Gnostic texts via Meyer — contribute contrasting accounts of paradise as literal place, as both sensory and intellectual realm, and as a cosmic love-union between divine principles. Abrams locates its Romantic aftermath in the secularized fall-and-redemption narrative. The term thus spans eschatology, soteriology, alchemy, and clinical psychology.
