Tolstoy was the greatest Russian of the 19th century. His life was full of setbacks and controversy. The following are his main shortcomings: 1. Noble birth: Tolstoy was born into a noble family, but his family was not stable in politics. He had been accused of being associated with the nobility and of supporting their opponents. 2. Writing style: Tolstoy's works usually have profound social significance and grand scale, but sometimes his writing style is too heavy and pessimistic, making people feel depressed. 3. Political views: Tolstoy's political views were more radical. He opposed the autocratic rule of the Tsar at that time and supported democracy and freedom. He had once been actively involved in politics, but in the end, he chose to stay away from politics. 4. Personal life: Tolstoy's personal life was relatively solitary. He was not good at socializing and often felt lonely and depressed. After his first wife passed away, he did not remarry and lived in his own home for a long time. Despite Tolstoy's many shortcomings, his works had a profound impact on the development of Russian literature and culture. He was considered the greatest of the 19th century.
