The ego–shadow–persona triad

Persona and shadow are not independent psychic entities parallel to the ego. They are the ego’s two facings. Stein names this topology with clarity: the shadow is “the backside of the ego” and “the unconscious side of the ego s operations of intending, willing, and defending” (Stein 1998, p. 107); the persona is “the face we wear to meet the social world around us” (Stein 1998, p. 106). The two are structurally tied to the ego they face outward from and inward from, and cannot be analyzed in isolation from it.

The consequence: any psychological work on the shadow is work on the ego’s boundary; any work on the persona is work on the ego’s adaptation. The ego is not the subject-matter alongside shadow and persona; it is the pivot on which both turn.
