In this work, I would like to consider a number of well-known texts by Ambrose of Mediolansky and Aurelius Augustine, try to build the most complete picture of mental life, trace, on the one hand, how the experience of ancient philosophy is transformed taking into account religious faith, on the other hand, what is the idea of ​ ​ the action of the psyche, what components are distinguished in it, how and why their work is described in this way. Identify key terms, describe their meaning. To trace how the concepts of immortality and ethereality are formed and maintained in connection with the body and bodily nature.
