The term ‘Call’ occupies a structurally pivotal position across the depth-psychology corpus, gathering meanings from at least four distinct registers: the Gnostic cosmological call from without, Heidegger’s existential-phenomenological call of conscience, Hillman’s acorn-theory notion of calling as daimonic destiny, and Campbell’s mythological call to adventure. In Gnostic literature, as Jonas documents, the Call is a transmundane event — a voice penetrating the closed world to awaken the pneumatic self to its alien origin. Heidegger radically secularizes this structure: the call of conscience summons Dasein from its absorption in the ‘they-self’ to its ownmost potentiality-for-Being, speaking in silence, bypassing public discourse. Hillman transposes the same logic into archetypal psychology, arguing that the soul’s daimon issues a call that shapes character and destiny from before birth — an invisible claiming force that cannot be reduced to nature, nurture, or superego. Campbell maps the call as the threshold event that inaugurates mythological heroic transformation, and identifies its refusal as an equally consequential existential act. Together these voices articulate a tension fundamental to depth psychology: whether the call originates beyond the self (Gnostic, theological, archetypal) or from within its deepest structure (Heidegger), and whether it demands a heroic response or constitutes the very ground of authentic selfhood.
