Within the depth-psychology corpus, ‘Beginning’ is not treated as a mere chronological marker but as a psychologically and philosophically charged threshold—the moment at which potentiality crosses into actuality, whether in cosmogony, individual development, or the initiation of action. The term carries several distinct valences across the library’s major voices. For Neumann, it is bound up with the archetypal stages of consciousness emergent from the uroboric void, where ‘beginning’ designates the pre-egoic matrix from which differentiation arises. Von Franz situates cosmogonic beginning within the interplay of fiery prima materia and the first stirrings of logos—mirroring the physicist’s primordial nebula and the alchemist’s originary substance alike. The I Ching tradition, as rendered by both Ritsema/Karcher and Wilhelm, treats beginning as a dynamic quality inscribed in the hexagram texts themselves: the ideogram for ‘begin’ encodes woman and eminence, signaling new life, while the logic of the Changes insists that every completion harbors a new beginning. Hillman recuperates beginning from linearity altogether, locating it in the senex–puer polarity and the alchemical inscription ‘beginning, middle, and end’ as a description of milk—prima materia at every stage. The Platonic tradition, voiced through Plato’s Phaedrus, grounds the philosophical argument that the beginning is unbegotten and therefore indestructible, the fountain of all motion. Taken together, these positions reveal a fundamental tension between beginning as cosmological origin and beginning as perpetually renewable psychological act.
