Dominant, Auxiliary, Principal, and Subsidiary Modes
The preceding chapter showed that quantifiying Jung’s personality theory inevitably leads to two modes in each domain—four in all. Jung himself considered only the principal one in each domain, giving the name “dominant” to the more prominent and “auxiliary” to the other. Quantitative theory identifies a new “subsidiary” mode in each domain, both absent from Jung’s entirely qualitative formulation. In another context, Jung regarded them as “positive shadows” (Jacobi 1942, p. 112), an interpretation discussed further in Sect. 8.3.
