Candide by Voltaire.

Candide by Voltaire.  Candide, by Voltaire, is a satirical novella published in 1759 that critiques philosophical optimism, particularly the idea that "all is for the best in this best of all possible worlds". The story follows the naive protagonist, Candide, as he endures a series of horrific and absurd misfortunes, leading him to reject his tutor Pangloss's optimistic teachings and ultimately conclude that the key to happiness is to "cultivate one's garden". It is a sharp, witty, and often dark satire of religion, government, philosophy, and human nature.
