The inferiority complex occupies a singular position in the depth-psychological corpus as one of the few clinical constructs to migrate from a specific theoretical school—Alfred Adler’s Individual Psychology—into the lingua franca of the entire field. Within the Seba library, the term surfaces most prominently not in Adlerian texts per se but in the work of authors who receive, contest, or reformulate Adler’s foundational insight: that a primary, constitutive sense of inadequacy drives the human organism toward compensatory strivings for power, perfection, or superiority. Hillman’s reading of Adler is philosophically the richest in the corpus, situating the inferiority complex within a broader mythopoetic tension between matter’s limitation and spirit’s aspiration. Jung, characteristically, indexes the term against his own architectonics of complex theory and compensation, treating feelings of inferiority as dynamically reversible phenomena—capable of generating their apparent opposites through overcompensation—and marking the inferiority complex as a recognizable index entry in his own clinical taxonomy. Horney engages the terrain most extensively through her delineation of neurotic self-contempt, self-effacement, and the tyranny of the idealized self-image, which collectively constitute a sophisticated phenomenology of inferiority without always invoking Adler by name. A recurring tension runs through these voices: whether the inferiority complex is best understood as a discrete psychopathological structure or as an inevitable moment within the dialectic of selfhood that normative development must traverse.
