The social essence is established in social institutions as forms of fixing the means of realization of a specialized activity which provides a stable functioning of public relations. Thus, the society is interested in the assistance
to the stability of social institutions which is ensured by the constitution, laws, and other normative-legal acts. Whenever social functions are not realized through formal rules, one says about an informal institution. Social institutions
are classified on the basis of functions they execute. We bear in mind economic, political, educational, cultural, and religious institutions, including social institutions in the narrow sense of this word.
