The article is devoted to the formation of the problem field of social phenomenology. The author analyzed the works of the phenomenological and socio-constructivist directions of research and identified a common conceptual core. The authors (T. Luckman, M. Merleau-Ponty, M. Eldred) distinguish a previously undifferentiated communicative horizon in the field of interaction. The communicative horizon belongs to the primordial sphere of the subject and is the result of the demarcation of the homogeneous world according to the criterion of ability to communicate.
