Vladimir Soloviev's comments

An interesting comment from the late 19th century Russian Philosopher Vladimir Soloviev: "The opposition between the two cultures-the eastern and the western- was already sharply delineated at the dawn of human history. If the East built the foundations of its culture on the ruthless subordination of man to a higher power, the supernatural, then in the West it was the opposite, man was left to his own invention, which allowed for a broad, self-generated creativity"

While I cannot really speak to his concept of 'Santa Sophia', he appears to write frequently about the Orthodox Church's development (and in relation with the Western Church as well)
