The text studies why does an aesthetic experience exist, what is its content and what is its informational role and structure? Has beauty any cognitive value? Can we analyse beauty? In what sense we can think about the information content of aesthetic experience? The second topic of the book is a cognitive role of emotionality and its research. Why we have emotions? What can they tell us about yourself and about the world?

The methodology of the study is designed as a phenomenological research of subjective experience that is combined with the newest results in Cognitive science research.
