3. What was the gist of the article in A Madman's Diary?

A Madman's Diary is a first-person Russian story about the protagonist Ivan Nikolayevich Sakhalin's fanatical pursuit of power and truth under the influence of extreme religious extremists. The article expressed Sakhalin's extreme ideology that only violence and revolution could solve problems, but violence and revolution brought pain and destruction. Sakhalin firmly believed in his own ideals and believed that he was the representative of God's will. He tried to dominate the world through fanatical beliefs and extreme actions. The Madman's Diary profoundly revealed the social reality of Russia at that time and the horror of religious extremists. It became an important work in the Russian intellectual and cultural circles at the end of the 19th century and the beginning of the 20th century. It had a profound impact on the later international capitalist movement and the enlightenment movement.
