The Kreutzer Sonata is a novella by Leo Tolstoy, named after Beethoven's Kreutzer Sonata. The novella was published in 1889, and was promptly censored by the Russian authorities. 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 of his wife: in his analysis, the root causes 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.
