In the late 1880s – early 1890s Tolstoy was very busy with works of art and articles on sexual love. In this time period he wrote “The Kreutzer Sonata”, “Afterword”, articles “On the relations between the sexes” and the beginning of “Father Sergius”. At the same time, Tolstoy extensively wrote about this theme in his letters to different persons, mostly to V. G. Chertkov. He wrote a novel , titled “The Devil” about the same subject.
