Structural and functional analysis and apportionment of a unit of inflience process are necessary to solve philosophical-psychological problems of educational influence of art. Extensive dialogic relationship characterized by bipolarity, ambivalence, integrity and dynamics can serve as such an unit. It enables the researcher to consider educational influence of art as an interaction of the object of art and the personality in subject-subject relationship. As a result the person under influence of art is assessed not as an inferior kind of artist but as a personality absorbing art values according to spiritual and social needs of one's cultural environment.
