Candide, ou l'Optimisme (1759) is a French satire by the Enlightenment philosopher Voltaire, English translations of which have been titled Candide: Or, All for the Best (1759); Candide: Or, The Optimist (1762); and Candide: Or, Optimism (1947). The novella begins with a young man, Candide, who is living a sheltered life in an Edenic paradise and being indoctrinated with Leibnizian optimism (or simply optimism) by his tutor, Pangloss. The work describes the abrupt cessation of this existence, followed by Candide's slow, painful disillusionment as he witnesses and experiences great hardships in the world. Voltaire concludes with Candide, if not outright rejecting optimism, advocating an enigmatic precept, "we must cultivate our garden", in lieu of the Leibnizian mantra of Pangloss, "all is for the best in the best of all possible worlds".
Candide is known for its sarcastic tone and its erratic, fantastical, and fast-moving plot. With a story similar to that of a more serious bildungsroman or picaresque novel, it parodies many adventure and romance clichés, the struggles of which are caricatured in a tone that is mordantly matter-of-fact. Still, the events discussed are often based on historical happenings, such as the Seven Years' War and the 1755 Lisbon earthquake. As philosophers of Voltaire's day contended with the problem of evil, so too does Candide in this short novel, albeit more directly and humourously. Voltaire ridicules religion, theologians, governments, armies, philosophies, and philosophers through allegory; most conspicuously, he assaults Leibniz and his optimism.
