The Kreutzer Sonata is a novella by Leo Tolstoy, named after Beethoven's Kreutzer Sonata. The work is an argument for the ideal of sexual abstinence and an in-depth first-person description of jealous rage. The main character, Pozdnyshev, relates the events leading up to his killing his wife; in his analysis, the root cause for the deed were the "animal excesses" and "swinish connection" governing the relation between the sexes. During a train ride, Pozdnyshev overhears a conversation concerning marriage, divorce and love. When a woman argues that marriage should not be arranged but based on true love, he asks "what is love?" and points out that, if understood as an exclusive preference for one person, it often passes quickly. Convention dictates that two married people stay together, and initial love can quickly turn into hatred. After he meets and marries his wife, periods of passionate love and vicious fights alternate. The work was banned in Russia and the US by the censors.
