This work tells about the study of the issue of the phenomenon “I” of the personal experience of a person’s perception of the world. In the course of my work, I tried to consider both the cultural aspects of this phenomenon and aspects of scientific knowledge about its nature. The goal of this work is to find points of contact between the cultural sphere of a person’s personality and his natural sphere in order to discover behind the total experience of all humanity the very beginning that underlies each specific individual. The very thing on the basis of which each individual person, turning to the cultural experience of other people, correlating their experience with his own cultural experience, affirms the natural foundation of this experience through personal thoughts, sensations and feelings, increasingly coming to an understanding of the phenomenon of “I”, the experience of personal worldview .
