On the category of “vital activity” of a person

According to their content, the substantive concepts of “nature” and “essence” in relation to a person in the functional aspect are revealed in the categories of “vital activity”, which has operational capabilities, that is, the ability to become a tool for a specific study of the process of human existence. It is shown that the restriction of the study of human life activity only by the sociological approach prevents the creation of a general theory of the human way of life, which, in turn, makes it possible to synthesize conceptual schemes of various aspects of life activity developed by special sciences. It is emphasized that it is not enough to analyze the ratio of social and physiological factors of a person, to refer only to his biological nature as a prerequisite for social, since this overlooks the relationship and interdependence of the natural and social aspects of the process of human existence. This connection can be revealed only by examining the process of functioning of the universal nature of man, that is, his vital activity.
