The Superego (n.) is the deposit of centuries of public opinion.
The Superego (n.) is, in Freud's sense, not an inherited part of the psyche but the consciously acquired moral code — a patriarchal legacy like the Ten Commandments.
The Superego (n.) is the self still projected onto public opinion: a necessary, unavoidable stand-in for actually experiencing the self.
The Superego (n.) is the sum of collective beliefs and values handed down by tradition — like the Torah for the orthodox Jew, a solidly entrenched system above the ego and the cause of many conflicts.
The Superego (n.) is our version of Lévy-Bruhl's collective representations: the tribal teachings by which civilized man, like the primitive, makes almost every choice without noticing.
The Superego (n.) was for Jung a furtive attempt by Freud to smuggle the old image of Jehovah into psychological theory, just as the school's stubborn father-complex is a misunderstood religious function.
