Christian Science is a 1907 collection of essays Mark 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 . He called her, according to American writer Caroline Fraser, "[g]rasping, sordid, penurious, famishing for everything she sees—money, power, glory—vain, untruthful, jealous, despotic, arrogant, insolent, pitiless where thinkers and hypnotists are concerned, illiterate, shallow, incapable of reasoning outside of commercial lines, immeasurably selfish." - Summary by Wikipedia, edited by John Greenman
