Candide by Voltaire

Candide is a relentless, brutal assault on government, society, religion, education, and, above all, optimism. Dr. Pangloss teaches his young students Candide and Cunegonde that everything in this world is for the best, a sentiment they cling to as the world steps in to teach them otherwise. The novel is brilliant, hilarious, blasphemous. . . and Voltaire never admitted to writing it.
