Within the depth-psychology corpus, ‘Youth’ occupies a structural position rather than a merely biographical one: it names a mode of psychic being, an archetypal orientation, and a cultural-historical force. The dominant framework is the senex-puer polarity elaborated by Hillman, in which youth signifies the puer pole—volatile, visionary, impatient with time and labor, resistant to the accretions of age. From this vantage, youth is not simply a developmental phase but a permanent psychological potential that can possess the individual at any age, or be permanently foreclosed by premature senex identification. Von Franz offers a corrective clinical emphasis: where youth as puer aeternus becomes pathological, it manifests as chronic impatience, boredom, and the refusal to commit—a paradise-of-childhood complex arrested in the adult psyche. Hillman further complicates the question by insisting that the cosmos through which one ‘insights’ youth—maternal, patriarchal, or otherwise—determines its very shape and trajectory. A separate strand of clinical literature treats youth empirically, as the adolescent population most amenable to wilderness and outdoor behavioral interventions. These two registers—archetypal and clinical-therapeutic—rarely converse directly, yet together they map the full range of depth-psychological engagement with the term.
