Regeneration occupies a pivotal position in the depth-psychology corpus, functioning simultaneously as a cosmological principle, a biological datum, and a psychic imperative. Eliade furnishes the most systematic treatment: for him, regeneration is the animating logic of archaic ritual life, expressed through the periodic annulment of time, the reenactment of the cosmogony, and the New Year’s ceremonial destruction and renewal of the world. What is primordial and essential, Eliade insists, is the idea of regeneration as repetition of the Creation — a structure he traces across Babylonian, Iranian, Egyptian, Hebrew, and East Asian traditions. Simondon approaches regeneration from an altogether different angle, interrogating the biological phenomenon whereby fragments of organisms reconstruct complete individuals, arguing that this capacity is not the privilege of a specialized germ but a general property of living matter — a finding with profound implications for theories of individuation. Conforti links biological regenerative activity in salamanders to electromagnetic field dynamics and, by extension, to archetypal field theory. Nagy locates regeneration in Greek heroic myth, where the cult of the hero’s bones embodies a formal promise of bodily reconstitution. Stein’s metamorphic imagery of larval dissolution anticipates psychic transformation. The central tension running through the corpus is between regeneration as cyclical cosmic event and regeneration as an individuating process — between the archaic aspiration to abolish time and the depth-psychological demand to transform within it.
