The Philosopher’s Stone stands as the supreme telos of the opus alchymicum and, within the depth-psychological corpus, as one of its most generative symbolic complexes. Jung’s foundational move — reading the Stone as a projected image of the individuated Self — recasts a metallurgical fantasy as a psychology of wholeness: the Stone’s paradoxical attributes (orphaned yet omnipresent, mortal yet eternal, male yet female) map precisely onto the Self’s transcendence of opposites. Edinger elaborates this reading with painstaking textual archaeology, demonstrating that the Stone’s described powers — transmutation, illumination, omniscience, union of solar and lunar principles — are phenomenological descriptions of psychic integration rather than chemical achievement. Abraham provides the philological scaffolding, tracing how the Stone migrates through alchemical literature as arcanum of arcana, composed of body, soul, and spirit, identical at times with the quintessence, the lapis angularis, the rock, the tincture, and even Christ. Von Franz and Jung press the Christological parallel most insistently: the Stone as filius philosophorum mirrors the filius macrocosmi, both figures of redemptive wholeness arising from base matter. Hillman, characteristically resistant to teleological readings, interrogates the Stone’s texture — its oily tenderness, its metallic curiosity, its dry intellectuality — and resists assimilating it too quickly to growth-and-transformation narratives. The central tension across the corpus is whether the Stone symbolizes an achieved psychic state (Self-realization) or an ongoing, never-quite-completed process of seeking.
