"Christian Science" by Mark Twain is a collection of essays Twain wrote about Christian Science, beginning with an article that was published in Cosmopolitan in 1899. Although Twain was interested in mental healing and the ideas behind Christian Science, he was hostile towards its founder, Mary Baker Eddy. In his commentary, he tells the tale of more than 120 fractures, some or many of which were visible to him, as well as 7 dislocated joints, including his hips, shoulders, knees, and neck. All of these were healed within three hours of the "Christian Science doctor's" visit. Immediately following this healing, he turns to the local country horse doctor to cure a headache and stomach ache.
