I'm puzzled by your use of the term "inferiority," even though I know quite well that it is central to Adler's work. To me, "inferiority" is an ideoaffective complex, a combination of cognitive structures and innate affects. Thus, when you speak of "inferiority feelings," I cannot locate these feelings in any known list of innate affects or complex emotions. What does this mean?
Additionally, I don't understand what you mean by "frustration." It seems to me that this, too, is a word that keeps us away from investigation of the affects involved. As well as I have been able to study it, frustration seems to occur when an action has been impeded. If this is true, then the feelings experienced in the moment of frustration would depend on the affects accompanying the original action and one's affective response to impediment.
I'd appreciate some instruction as to your use of these common words.
