Russian writer Leo Tolstoy is considered one of the greatest novelists of all time. War and Peace and Anna Karenina have inspired millions over the last century. Less well-known about Tolstoy, though is that he had a profound effect upon many due to his interpretation of Christian ethics, especially regarding non-resistance and pacifism. In 1884, he expounded upon his beliefs in What I Believe, and this work was promptly banned in Russia for its negative depiction of the state and the Russian church. After the book had spread throughout the world and garnered attention, Russian secular and religious intellectuals began attacking his ideas. The Kingdom of God is Within You, published in 1894, is a further explanation of his beliefs and a response to his opponents.
