The term ‘Receptacle’ traverses the depth-psychology corpus along two intersecting axes: the Platonic-cosmological and the psychological-symbolic. In Plato’s Timaeus — the foundational text for the term’s philosophical career — the Receptacle (chōra) is the characterless, all-receiving, invisible ‘mother and nurse of all Becoming,’ a third principle beside the eternal Forms and the sensible copies. It is neither matter in the Aristotelian sense nor void, but an enigmatic spatial matrix that sustains the impressions of intelligible forms without itself assuming any. This Platonic legacy flows directly into the depth-psychological literature. Jung mobilizes the concept to distinguish two functions of the unconscious: as a mere ‘receptacle’ for repressed or antipathetic contents (the Freudian view), and, more fundamentally, as the generative matrix from which new psychic contents arise. The Gnostic material — treated extensively by Jonas — extends the metaphor to the soul itself, conceived as a receptacle occupied by warring spiritual forces, gods or demons in turn. Neumann and the alchemical commentators (Abraham, von Franz, Hillman) transpose the receptacle into the symbolic register of vessel, womb, and transformative container. Corbin’s Sufi sources add yet another inflection: the heart as receptacle whose capacity measures the degree of theophany it can receive. The term thus marks a persistent tension between passivity and productive transformation.
