Abstract: The subject of the research is poetry as part of human world, i.e. anthropocosm. Morkina understands anthropocosm as the subject of cultural evolution and the world immanent to human - the world of meaning-ful mental phenomena. Just like William James and Edmund Husserl, the researcher understands consciousness as a flow of meanings. Being an intentional object, any consciousness phenomenon is a complex system of meanings. This is true for the phenomenon of a poetical composition. Poetical part of human world is viewed by the author of the article based on a concrete example, i.e. analysis of a poem 'The Sun' written by a modern poet Denis Karasev. The researcher provides a detailed analysis of Denis Karasev's poem by using phenomenological methods. Morkina views both the entire anthropocosm (human inner world) and poetical part of anthropocosm from the phenomenological point of view. In her anaysis Morkina tries to view poetry from the point of view of a philosopher but not a literary critic. The researcher introduces the term 'anthropocosm' and defines it as heuristic for the phenomenological research of human world. The definition implies conceptualization of human world that is understood as the entire humanity. The author of the article demonstrates that phenomena (intentional mental objects) create united systems. The main feature of these sytems is their meaningfulness. Anthropocosm is the greatest phenomenon system that includes components of all human meaning systems: all initial meanings - sensations, all human-dimension phenomena, all particular worldviews of certain sciences. For the first time in the academic literature the author demonstrates that a poetical composition is a complex ideal meaning systems included in the cultural evolution.
