After Le Dernier jour d'un condamné, Hugo published Claude Gueux, a short story of how a smart but hardly educated poor worker, Claude, stole things to feed his family for three days at the expense of being jailed for five years. The first part is about Claude's life in jail, during which he killed the warden due to unreasonable legal treatment and finally was executed. The storyline is meant to introduce Hugo's statements in the second part, including his denouncement against the capital punishment, reflection about the society and the ideals he entrusted to education. Hugo advocated that people needed cultivating, developing, nurturing, enlightening, teaching and working rather than having them executed to show the harshness of the punishment after they made big mistakes. Here we would explain and explicate Hugo's ideals and analyze his cure for the poverty of the 19th century.
