The article describes the main components of the model of psychogenesis, considered in several aspects: logical, evolutionary (historical) and ontogenetic. It is shown that attempts to search for the basics of the psyche in the structure of the nervous system are meaningless, since it is first necessary to find out the real role of the nervous system in the process of adaptation of the organism to the environment. To solve this problem, it is required to describe the basic physical characteristics of the environment. The article claims that the process of psychogenesis is a complex multilevel phenomenon that must be considered in at least four aspects: mathematical, physical, anatomical and physiological and psychological.
