Probably bullshit but I wondeer if anything has been written on this:
I've read the Tertiary fucntion described as the "secret motivation";
and the inferior judged as the "projection", i.e. that which we feel imposed on us by the external world;
and the dominant and secondary I guess are the ways in which we primarily interact with the outside world, i.e. our consciously expressed and outwardly visible "personality";
So to what extent does the Tertiary correspond to the Id; Inferior to the Superego; and the 2 dominant functions to the Ego...?
