The professions of psychology and psychiatry, the former involving psychoanalysis by conversation and hypnosis and rooted in primal human sexuality and memories of it, and the latter in the physiology, biochemistry and neurology of the brain have come a long way from the founders of psychology, Freud and his student Jung.
While Freud focused on the common human tripartite nature of the soul – the id or primal instinctive urges, a normal sense of self or the ego for day-to-day functioning, and the tendency to envision and act on transformative changes in the world or super ego – and attributed to this conception the discontents of civilization in his treatise Civilization And Its Discontents, Jung abstracted from the natural and biological/sexual nature of the human psyche to the nurtural or cultural aspects of it to expound on the collective subconscious of a society (or culture as sociologists understand it) in The Archetypes and The Collective Unconscious. Ever since, the principal debate among psychologists has been either Freud or Jung, not Freud and/both Jung though this is the reality of how the world works.
The following simple figure should serve as conceptually self-evident to synthesize the two giants, Freud and Jung, to better understand the process of the integration of peoples across cultures or ethnicities primarily characterized by differences in native languages and secondarily by race.
The top panel is Freud’s tripartite soul and Dante Alligheri’s Divine Comedy which preceded the Renaissance, Protestant Reformation and Henry VIII Anglican split from Rome by at least a century. The Christian Church in Europe was divided two ways: Greek and Slavic orthodoxy and Rome.
The left panel is the relationship of Jung’s collective unconscious (cultural self) with (the) (an)other (cultural self).
The “X”s correspond to the overlapping of Jung on Freud, explaining the derivation of the collective unconscious from the biological survival instinct.
It will be clear from psychological data gathering that survival is maximized in the super ego (the psychological hermeneutic for heaven) and minimized in id (the psychological hermeneutic for hell). It is optimized in the ego (the psychological hermeneutic for earth, the cradle of the species).
