The paper try to identify the ways, how choosen czech beletristic books speak about different ways of understanding to values, life-styles or ways to behaving of adolescents and parent’s generations in the time before and after the rovolution in the end of 1980’s and the beginning of 1990’s. The main question is about level of representation of generation’s breakage in chosen beletristic literature. From this perspective, the paper analyze the belteristic works by Irena Dousková, Jan Balabán, Tereza Brdečková, Edgar Dutka, Jiří Hájíček and Petry Hůlová. The representation of generation’s breakage is situated to the context of classical and modern sociology of generations (Mannheim, Gasset, Corsten, Giesen, etc.). It is important to show the relationship between the dramatic historical experience and daily-based experience and behavior, also the subjects of investigation are the areas of experience and behavior, in which the differences among generations are articulated (the family, the job, the education, the entertaining, the language, the religion, etc.) The objective of this paper is not to evaluate preciseness of literature description based on some “scientific” information. More to the contrary the literature represent a picture of our experiences as the social agents, that means that this experience can not be evaluate as good - bad or correct – incorrect. As a part of this paper is also question of relationship of belletristic literature and sociology, however this is not the main point of the interest.
