Metaphysical closure, as it moves through the depth-psychology corpus, names the philosophical problem of whether any system of thought — ontological, psychological, or biological — can arrive at a final, self-sufficient ground that permits no remainder. The term operates on at least three distinct registers. In Derrida’s deconstructive reading of the Western philosophical tradition, metaphysical closure designates the epochal determination of Being as presence: the long history in which philosophy has sealed itself within the authority of self-evidence, formal logic, and transcendental consciousness, a movement Husserl’s phenomenology carries to its extreme limit. Giegerich inherits this critique but redirects it: for him, depth psychology cannot purchase its freedom from classical metaphysics cheaply; the underlying soul-issues preserved in the metaphysical tradition — truth, the absolute, identity — must be traversed rather than evaded, or psychology merely retreats into playful imaginal naivety. From a biosystemic vantage, Thompson’s engagement with Varela reframes closure entirely as operational self-organization, stripping it of ontological finality and making it a functional, not a terminal, category. A residual tension persists throughout: whether closure is a philosophical pathology to be dissolved, a structural necessity of living systems, or a goal the psyche itself desires — what Woodman registers as the soul’s painterly struggle toward metaphysical resolution.
