The contribution of Slavic literatures to the development of world literature

Defining the concept of "world literature" can hardly be achieved without effort and polemics, as it probably seems to many who are accustomed to it. It is indeed not easy to give a decisive answer to questions such as: which are the literatures that have managed to impose their achievements as conquests of the entire human society; what guides a development that runs through the entire history of mankind; what are the ingredients, criteria and drivers of the process that merges the achievements of folk and national literatures into one and at the same time fertilizes folk and national literatures; and so on.
