In the current study, we are talking about a certain marginal characterization of the singularity and personality, which we will designate as "the uniqueness of personal being". From our point of view, within the framework of the dialectical approach, "unique" is interpreted as a category that reveals a set of non-essential features of single objects that form their uniqueness, understood as an ontological state of non-proliferation, irreplaceability and extraordinary. "Unique" as the ultimate form of the singular - the solemness of the singular - has an indirect dialectical transition (in historicity and formation) through the special to the ultimate form of the general - "universal". The dialectical contradiction between the unique and the universal is revealed in particular, through the particular these opposites are both separated and identified. Moreover, these trends are manifested not only at the intrapersonal level but also at the level of intergenerational transfers within the family. The problem of finding a scientific language to describe the uniqueness of personal being, the introduction of the philosophical category "unique" into the methodology of the sociological and anthropological study is still little studied and requires further study.Keywords: Unique, person, being, interpersonal communication, paradigm.
