Scientific discussion between Buslaev and Pypin on history of Russian literature

The scientific discussion between Buslaev and Pypin resolving some issues of Russian literature had a general methodological meaning. Some differences of their world outlook (Buslaev had holy-paternal views, Pypin had positive approach) led to different interpretations of the concepts of "double" faith, poetic of literature, Visantium's influence, periods of literature. In contrast to Pypin Buslaev suggested studying poetics historically. He regarded "double" faith widely and considered Visantium direction as very positive for Russian culture.
