Neumann uses myths, particularly myths of the hero in the process of surviving various monsters that can be equated with aspects of the unconscious, to find evidence of the ego’s emergence, survival, and progressive strengthening, thus organizing the myths along a continuum of the hero’s progress to generate a stage-by-stage model of ego development.
Beebe identifies Neumann’s hero-myth schema as the principal Jungian model of ego development, while noting its subsequent critique as Apollonic and progress-bound.
