Dissolution occupies a pivotal position in the depth-psychology corpus, functioning simultaneously as an alchemical operation, a psychological process, and an existential threshold. The term enters the literature primarily through the Hermetic formula solve et coagula, where, as Abraham’s lexicographic work documents, it names the reduction of consolidated matter to prima materia — a necessary precondition for any authentic transformation. Jung and his interpreters (Edinger, Hillman) translate this alchemical valence directly into psychological terms: dissolution describes the liquefaction of fixed psychic structures — the persona, the ego, hardened complexes — so that a more essential substrate may be reconstituted. Edinger’s careful reading of solutio in Mysterium Coniunctionis emphasizes the moon’s dual capacity to coagulate and dissolve, framing dissolution as neither catastrophe nor mere regression but as a phase within a rhythmic cycle. Hillman, characteristically, pushes further, reading dissolution as the work of Dionysian consciousness, arguing that the dispersal of psychic structures releases a pneuma distributed throughout the very matter of the complexes. The term also surfaces in contemporary consciousness research (Sun & Kim) under the banner of ego-dissolution, measurable via the Ego-Dissolution Inventory, linking it to altered states and shamanic practice. Burkert supplies a ritual-anthropological counterpoint, situating dissolution within communal cycles of sacrifice and renewal. Across these positions, dissolution is not opposed to life but constitutes its recurring initiation.
