Dryness occupies a remarkable range of registers in the depth-psychological corpus, moving between the archaic-physiological, the elemental-cosmological, and the archetypal-structural. In the oldest stratum, represented by Onians’s recovery of Greek thought, dryness defines the condition of the dead: the corpse dries as life-liquid departs, and the soul (psyche) at its wisest and best is itself dry — a Heraclitean paradox that Sullivan and Claus both document. This physiological semantics feeds directly into the pneumatic psychology of the phrenes, where dryness of the respiratory vessels signals clarity and conscious alertness. In the alchemical register, von Franz situates dryness within the quaternary of elemental qualities — warmth, cold, moisture, dryness — as constitutive of the prima materia’s transformations, while Hillman’s alchemical psychology links salt, sulfur, and desiccation to processes of thickening, preservation, and psychic solidification. Moore’s Ficinian framework assigns dryness specifically to Saturn and to spirit, making it a marker of melancholic depth, rigidity, and the senex archetype, a connection Hillman develops explicitly: dryness, coldness, and winter are phenomenological signatures of the senex principle. Nussbaum’s philosophical reading of Platonic eros introduces dryness as the affective residue left by an absent beloved, a parched longing that purity-ideals cannot sustain. The I Ching tradition adds dryness as the elemental signature of the Clinging trigram, linking it to fire, heat, and psychic firmness hollow within. Across these traditions the tension is consistent: dryness indicates either the highest lucidity of consciousness or the deathly arrest of vitality.
