sentences:  Social rule system theory is fundamentally an institutionalist approach to the social sciences, both in its placing primacy on institutions and in its use of sets of rules to define concepts in social theory.Social rule system theory notes that most human social activity is organized and regulated by socially produced and reproduced systems of rules.These rules have a tangible existence in societies – in language, customs and codes of conduct, norms and laws, and in social institutions such as family, community, market, business enterprises, and government agencies.
