Since social relations are the foundation of social life, it is also a central concept in sociology. This concept must therefore be conceptualized in a way that allows for its operationalization and its empirical study. Once this understanding achieved, a new social theory can be constructed. In this article, the author attempts to define the notion of social relations, to distinguish different types of social relations, and to show how this notion allows one to articulate the sense of culture and the constraints of social life.
