The article is devoted to the analysis of such properties of normativity as ascriptivity and descriptivity, as well as the principle of the evolutionary development of norms. The article defines the content of the concept of “norm”, identifies two main interpretations of it: as a combination of a standard set of properties and as a sample of desirable behavior. It is argued that the second interpretation forms the idea of social norms. The problem investigated in the article is the presence of various properties of social norms and their corresponding requirements for people’s actions.
