The metaphysics of consciousness constitutes one of the most contested and generative axes in the depth-psychology corpus, cutting across traditions from Aurobindonian integral idealism to Jungian analytical psychology, from McGilchrist’s hemispheric philosophy to Derridean deconstruction. The central question — whether consciousness is ontologically primary or derivative — receives sharply divergent treatments. Sri Aurobindo argues from a thoroughgoing spiritual monism: consciousness is the very substance of existence, and matter is no more than a ‘status of being of Spirit.’ McGilchrist, marshalling testimony from Planck, Schrödinger, and Heisenberg, insists that consciousness cannot be reduced to anything more fundamental and that the materialist project of grounding mind in matter is self-defeating, since matter itself ‘evanesces’ under scrutiny. Pauli occupies an intermediate position, resisting both Eastern ‘suprapersonal cosmic consciousness without an object’ and naive physicalism, proposing instead that the unconscious stands in a complementarity relation to consciousness analogous to quantum complementarity. Derrida, by contrast, approaches consciousness through the critique of self-presence, arguing that consciousness manifests only as self-presence and that this privilege encodes the entire metaphysics of the subject. The depth-psychological tradition is thus the site of a genuine encounter between idealism, panpsychism, complementarity theory, and post-structural critique — making this entry indispensable for situating the broader library.
