Ego-centered psychology names a configuration of assumptions — and, for the depth-psychological tradition, a critique — in which the ego is installed as the sovereign center of psychic life, the arbiter of reality, and the primary subject of therapeutic concern. The corpus reveals two broad registers in which this term operates. The first is descriptive: a cluster of thinkers from Edinger to Samuels to Stein map the structural relations between ego and Self, noting that wherever the ego mistakes itself for the whole it generates inflation, alienation, and what Edinger calls damage to the ego-Self axis. The second register is polemical and belongs chiefly to James Hillman, whose archetypal psychology mounts a sustained assault on what he calls ‘the monotheistic hero myth (now called ego-psychology),’ condemning its single-centered, self-identified consciousness as both philosophically impoverished and clinically destructive. Buddhist-inflected voices such as Spiegelman reinforce the critique from a contemplative direction, identifying the non-ego-centered personality as a therapeutic and spiritual goal. Rudhyar approaches the same tension astrologically, distinguishing the ‘Earth-centered ego and his will’ from the ‘solar Self.’ Across these diverse idioms, ego-centered psychology functions as a contested term — simultaneously a developmental necessity and a pathological danger — whose critique opens space for polytheistic, imaginal, and transpersonal alternatives.
