By ‘successful socialization’ we mean the establishment of a high degree of symmetry between objective and subjective reality. - Peter L. Berger

Specific procedures of universe-maintenance become necessary when the symbolic universe has become a problem. As long as this is not the case, the symbolic universe is self-maintaining, that is, self-legitimating by the sheer facticity of its objective existence in the society in question.

A society’s stock of knowledge is structured in terms of what is generally relevant and what is relevant only to specific roles… the social distribution of knowledge entails a dichotomization in terms of general and role-specific relevance… because of the division of labor, role-specific knowledge will grow at a faster rate than generally relevant and accessible knowledge… The increasing number and complexity of [the resulting] sub universes [of specialized knowledge] make them increasingly inaccessible to outsiders.

Society... directly penetrates the organism in its functioning, most importantly in respect to sexuality and nutrition. While both sexuality and nutrition are grounded in biological drives, these drives are extremely plastic in the human animal. Man is driven by his biological constitution to seek sexual release and nourishment. But his biological constitution does not tell him where he should seek sexual release and what he should eat.
