Within the depth-psychology corpus, ‘Nothing’ occupies a position of surprising philosophical density, functioning not as mere absence but as an active, generative ground. The term traverses at least four distinct registers. In the mystical-theological register — represented by Eckhart, Boehme, and the Gnostic Apocryphon of John as read through James, McGilchrist, and Meyer — Nothing names the apophatic ground of divinity: ineffable, prior to differentiation, paradoxically more real than any positive content. In the ontological register, Heidegger’s ‘das Nichts selbst nichtet’ (Nothing noths) receives sustained attention from McGilchrist as evidence that Nothing is agentive rather than merely privative — a move that aligns structurally with Eckhart’s negatio negationis and the Taoist and Kabbalistic withdrawal-as-creation. In the Schopenhauerian-ascetic register, Nothing designates the terminus of will-negation: the apparent void into which the saint passes and which, Schopenhauer admits, only appears empty from within the perspective of will. Finally, in the Jungian analytic register, Jung’s seminar deploys Nothing as a logical counter — the ‘nothing in the unconscious’ whose opposite, ‘something,’ marks psychic integration. These positions share a common tension: is Nothing a destination to be sought, a logical limit, or the secret plenitude underlying all manifestation?
