Dilemma between the universal humanity and nationalism was often discussed in the contemporary philosophy of politics. We will considered discussion about this problem between Soloviov and Danilevsky, two great Russian thinkers of the 19th century. The first defended idea of universal humanity and criticized Danilevsky because of nationalism. We will show that Danilevsky's arguments were stronger and that Soloviev's critics were not successful. The discussion was conducting on three levels: methodological, factual and normativ ones.
