Within the depth-psychology corpus, ‘Existence’ is not a settled metaphysical given but a term under continuous interrogation across ontological, phenomenological, and contemplative registers. Aurobindo reads Existence as the first term of Sachchidananda — an eternal, self-luminous reality inseparable from Consciousness and Bliss — against which unconsciousness, pain, and individual separateness are revealed as surface distortions rather than fundamental facts. Jung, by contrast, grounds existence epistemologically: psychic existence is declared the only category of existence of which we possess immediate knowledge, making the psyche the sine qua non of any knowable world rather than a mere epiphenomenon of biology. Merleau-Ponty refuses to privilege either body or consciousness as the origin, locating existence instead in the irreducible ambiguity of incarnate being, where body and existence presuppose one another without reduction. Heidegger’s Dasein makes existence a temporal and ontological burden — always mine, always towards-death, never simply present-at-hand. Giegerich sharpens this by insisting that the soul does not exist as an entity at all, but is logical life, movement preceding Being rather than a mode of it. Descartes and Plotinus supply the classical poles: existence as necessary predicate of divine perfection versus derived, dependent being reflecting Authentic Being. The term’s depth-psychological valence, then, spans from existential facticity to ontological plenitude, with the status of psychic existence as its most contested and generative node.
