The life course, as the depth-psychology corpus construes it, is far more than a sociological timeline: it is the psyche’s primary arena of transformation, the medium through which individuation, liminality, and narrative identity acquire their stakes. Janusz and Walkiewicz establish the structural backbone, identifying the preservation of the life course’s sequential order as itself a clinical and psychodynamic value — its disruption producing psychopathological symptoms ranging from family dysfunction to depressive chronicity. Murray Stein maps a lifespan schema of metamorphic stages — childhood, adolescence, midlife, old age — each punctuated by crises that are, in Jungian terms, invitations to deeper selfhood. Benda draws on Elder’s life-course theory to locate ‘turning points’ as moments of social bonding that redirect developmental trajectories, integrating sociological and spiritual variables. Singer and his collaborators bring the narrative dimension: the life course becomes the substrate upon which identity is storied across the adult lifespan, with meaning-making capacity deepening through progressive cognitive and affective stages. Rudhyar, working from astrological cyclology, articulates a numerologically structured developmental arc of 28-year cycles. What unites these disparate voices is the insistence that the life course is not merely elapsed time but patterned, purposive, and interruptible — and that depth psychology’s task is to discern the organizing principles beneath its apparent contingency.
