Hermes Trismegistus

Why Is the Hermetic Tradition the Connective Tissue of Depth Psychology?

“As above, so below; as below, so above.” This axiom from the Emerald Tablet — attributed to Hermes Trismegistus — is the single most consequential idea in the Western esoteric tradition. It asserts that the structure of the cosmos is mirrored in the structure of the individual soul, that the same patterns operating in the macrocosm operate in the microcosm of human interiority. Jung recognized this principle as the philosophical foundation of everything he was doing. In Psychology and Alchemy, Jung demonstrated that the alchemists were not primitive chemists but symbolic psychologists who projected the drama of individuation onto matter — and that they could do so only because the Hermetic tradition had already established the correspondence between outer world and inner world (Jung, CW 12).

The Corpus Hermeticum, a collection of dialogues and treatises compiled between the first and third centuries CE, presents a cosmology in which the human being is a microcosmic mirror of the divine order. The soul descends through the planetary spheres, acquiring the qualities of each, and its task is to reascend through self-knowledge — to remember its origin in the divine mind. This descent-and-return pattern is the template that would reappear in Gnostic mythology, Neoplatonic philosophy, and medieval alchemy before being reinterpreted by Jung as the archetype of individuation (Jung, CW 12).

The Hermetic tradition is not a single school but a current that runs beneath the entire history of Western depth thought. It bridges Egyptian initiation, Greek philosophical inquiry, Gnostic soteriology, and the alchemical opus. Without it, the alchemical tradition that Jung spent decades interpreting would not exist, and depth psychology would lack its richest symbolic vocabulary.

How Did Jung and His Successors Use the Hermetic Inheritance?

Jung’s two great alchemical works — Psychology and Alchemy (CW 12) and Mysterium Coniunctionis (CW 14) — are sustained engagements with the Hermetic tradition. In CW 12, Jung traced the parallel between the alchemical opus and the individuation process, showing how the nigredo (blackening), albedo (whitening), and rubedo (reddening) correspond to stages of psychological transformation (Jung, CW 12). In CW 14, he devoted his most ambitious work to the coniunctio — the union of opposites — which the Hermetic tradition had symbolized as the marriage of Sun and Moon, King and Queen, sulfur and mercury (Jung, CW 14). The Emerald Tablet’s claim that “what is below is like what is above” gave Jung the philosophical warrant to read alchemical symbolism as psychological reality.

Von Franz extended this work, showing how the Hermetic emphasis on matter as ensouled — not dead but alive with psychic significance — ran directly counter to the Cartesian split that modern psychology inherited (von Franz, 1980). Hillman’s Alchemical Psychology drew on the same Hermetic inheritance, insisting that the soul’s relationship to the body and to the material world is not incidental but essential to its nature (Hillman, 2010). At Seba.Health, this lineage — from the Hermetic axiom through alchemical psychology to convergence psychology — forms the Body-Soul Thread, the recognition that psyche and soma are not separate domains but two faces of a single reality.
