Candide by Voltaire.
Voltaire wrote.
Ever since 1759, when Voltaire wrote "Candide" in ridicule of the notion that this is the best of all possible worlds, this world has been a gayer place for readers.
The novella has been widely translated, with English versions titled Candide: or, All for the Best (1759)
Candide: or, The Optimist (1762); and Candide: Optimism (1947).
Candide, ou l\'Optimisme, is a French satire first published in 1759 by Voltaire, a philosopher of the Age of Enlightenment.
