Hello George,
I just took a closer look to "Goal of fictional superiority". I guess that maybe it can be better to speak of the "Fictional goal of Superiority". Adler used the German word "Ziel" and "Zweck" alternatively to indicate the individual "for what purpose?" or "to what end? ".
Superiority as such made some kind of development in Adler's thinking. In his writings around 1920 he used "Uberlegenheit" ( Superiority). Later around the 1930's he saw it more as a striving for "Overcoming" and "Perfection" and "Completion". I guess you know that in the end he spoke of a movement from a felt minus to a perceived plus.
