Psychogenic

1. Etymology

Psychogenic describes mental disturbances having a psychological rather than physiological origin. Related: psychogenesis; neurosis; psyche; psychoid (border, not synonym).

2. Plain summary

Sharp’s head is clinical and short: psychogenic means the essential cause—or the condition under which a disturbance arises—is of a psychic nature. Classic instances: psychic shock, gruelling conflict, wrong psychic adaptation, fatal illusion. Jung’s line that “nobody doubts that the neuroses are psychogenic” anchors the house neurosis leaf; this lemma keeps the adjective itself.

Psychogenic is not psychoid. Psychoid names the psyche–matter border and the archetype as such; psychogenic names etiology that is psychological rather than organic. Related: abaissement-du-niveau-mental as a facilitating condition for some psychoses Jung also treated as largely psychogenic.

Examples (exhaustive house list for this Index lemma — common psychogenic motifs named across Jung’s essays and standard Jungian lexica; not a claim that Jung’s CW contains only these):
psychological vs physiological origin; essential cause of neurosis psychic; psychic shock; conflict; wrong adaptation; fatal illusion; distance from organic monocausality; not synonym of psychoid; kinship with psychogenesis of schizophrenia debates (Jung reserved judgment on biological contribution).

3. Academic elucidation

In analytical psychology psychogenic is an etiological adjective locating the decisive condition of a disturbance in psychic process. Sharp alone carries a dedicated head citing CW 3 ¶496; Samuels has no separate psychogenic lemma this vessel pass (route via neurosis / psyche). Do not invent loci.
