The author reveals Fyodor Dostoevsky's works main features, his importance for Russian and world philosophy. The researcher analyzes the concept of "Russian Idea" introduced by Dostoyevsky, which became a study subject in Russian philosophy's subsequent history. The polemics that arose regarding the characteristics of Dostoevsky's soilness ( Pochvennichestvo ) ideology and his interpretation of the Russian Idea in his Pushkin Speech and subsequent comments in A Writer's Diary are unveiled. The author concludes that Dostoevsky overcomes the limitations of soilness and comes to universalism. The universal for him does not have a rootless cosmopolitan character but is born from the national's heyday. Diversity adorns the truth, and national diversity enamels humankind. People's real unity is in that all-human value that is found in the highest examples of each national culture. The truth is not in rootless cosmopolitanism or nationalism - it is in the "golden mean," which, in our opinion, the writer-philosopher sought to express. Dostoevsky wanted to rise above the dispute, to recognize the points of view of the Slavophiles and Westernizers as one-sided, to get out of any particularity to universality.
