We are social beings; thus, we have social identities. Our social life is impossible without a framework and basis for developing social and individual identities — without them no one can build meaningful or consistent relationships with other people. Social identity as the basis for identifying socially significant “similarities” and “differences” between individual and collective actors allows for continuous communication and sustainable interactionin the community. Explanations of social identity and factors influencing its cannot be limited to any theory or scientific school. Thus, the authors study the concept of social identity as defined by theories of macro- and micro-levels, and also by theories of social order and integration. The article starts with the macro-sociology theorists E. Durkheim and M. Castells and considers such concepts as “mechanical solidarity”, “organic solidarity”, “legitimizing identity”, “resistance identity” and “project identity”. The authors consider the views of representatives of the symbolic interactionism focusing on the concepts of “self” and “mind”, primarily in the theory of G.H. Mead; the ideas of Ch.H. Cooley based on the concepts of “looking-glass self” and “primary group”; the works of M. Rosenberg devoted to “self-concept”; the theories of H. Tajfel and A. Giddens describing identity and its varieties; and, finally, the views of P. Bourdieu and R. Jenkins. The authors conduct a kind of the preliminary comparison of the mentionedapproaches to identify the features of their theoretical argumentation and the role of ‘identity’ in the theory of social order and theoretical-methodological dilemma ‘subject-structure’.
