The doctoral thesis will analyze the ideological influence of the Russian philosophical and cultural environment on Slovak philosophical and political thinking. It will bring closer the ideological sources that fundamentally determined the perception of freedom, human dignity, religion and nation in the thinking of Slovak thinkers and their approach to the philosophy of history in the second half of the 19th century. The project examines the philosophical influence of Slavophiles on the spread of various interpretations of Slavic mutuality in the nation-building process.
