The doctrines of Aleksey Khomyakov, Ivan Kireyevsky (1806–56), Konstantin Aksakov (1817–60) and other Slavophiles had a deep impact on Russian culture, including the Russian Revival school of architecture, The Five of Russian composers, the novelist Nikolai Gogol, the poet Fyodor Tyutchev and the lexicographer Vladimir Dahl. Their struggle for purity of the Russian language had something in common with ascetic views of Leo Tolstoy. The doctrine of sobornost, the term for organic unity, intregration, was coined by Kireyevsky and Khomyakov. It was to underline the need for cooperation between people, at the expense of individualism, on the basis that opposing groups focus on what is common between them. According to Khomyakov, the Orthodox Church organically combines in itself the principles of freedom and unity, but the Catholic Church postulates unity without freedom, and in Protestantism, on the contrary, freedom exists without unity. In the Russian society of their time, the Slavophiles saw sobornost ideal in the peasant obshchina. The latter recognized the primacy of collectivity but guaranteed the integrity and the welfare of the individual within that collective.
