The concept of human being inner nature is the central core of A. Maslow's humanistic psychology program. His spiritual testament - "Toward a psychology of being" - contains two models, two views on human inner nature. One of them represents it from the position of ethical naturalism as inner quite individual and self-reliant factor of human full value. The other approach considers human inner nature to be a result of specific vital material's development beginning with the start of ontogenesis. The features of the second model are analyzed and interpreted with the aid of cultural-anthropological imprinting notion.
