I have read a great deal by Tolstoy including his philosophical and religious works as well as several biographies. From what I've read, he was a restless man who was tormented by numerous demons that he couldn't put to rest. In some ways, he was constantly wrestling with himself and God because he wanted everything to be absolutely perfect. As far as his writings are concerned, I have always found that his literary works (Anna Karenina, various short stories, Resurrection) are enlightening and shine a profound light on the human condition. However, he is nowhere near Dostoyevsky or Solzhenitsyn (my favorite Russian authors).
