"The basic contentions of the argument of this book are implicit in its title and sub-title, namely, that reality is socially constructed and that the sociology of knowledge must analyse the process in which this occurs."

“Social order is a human product, or more precisely, an ongoing human production.”

“Theoretical knowledge is only a small and by no means the most important part of what passed for knowledge in a society… the primary knowledge about the institutional order is knowledge... is the sum total of ‘what everybody knows’ about a social world, an assemblage of maxims, morals, proverbial nuggets of wisdom, values and beliefs, myths, and so forth.”

“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 sub universes make them increasingly inaccessible to outsiders.”

“The individual... is not born a member of society. He is born with a predisposition towards sociality, and he becomes a member of society. In the life of every individual, therefore, there is a temporal sequence, in the course of which he is inducted into participation in the societal dialectic. The beginning point of this process is internalization : the immediate apprehension or interpretation of an objective event as expressing meaning, that is, as a manifestation of another's subjective processes which thereby becomes subjectively meaningful to myself.”

“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.”

“There are very few jokes about sociologists.”
