Fixation (n.) on the family follows a man everywhere: the unconscious recreates the infantile milieu by projecting his complexes, reproducing the old dependence in defiance of his vital interests.
Fixation (n.) can be read two ways: libido streaming back to childhood, or parts of the personality not yet born — still as though in the womb.
Fixation (n.) is the libido lingering too long at stations on its way from the nutritive to the sexual function; as development goes on regardless, the gap between persisting infantile activity and adult demands breeds the conflict at the base of neurosis.
Fixation (n.) is Freud's notion that the neurotic stays attached to an infantile stage; Jung found it fails to explain neuroses that break out only at critical moments of new adaptation, and saw less a fixation than a peculiar use made of the infantile past.
Fixation (n.) means the stone to the alchemists, but psychologically it is the consolidation of feeling: the distillate of insight must be held fast as a firm conviction and permanent content.
Fixation (n.) is what Jung's psychical inertia, made the precondition of neurosis, names — hardly a better name: very early linkages of instinct and object that bring development to a standstill.
