Brave New World's title derives from Miranda's speech in William Shakespeare's The Tempest, Act V, Scene I:
O wonder! How many goodly creatures are there here! How beauteous mankind is! O brave new world, That has such people in't.— William Shakespeare, The Tempest, Act V, Scene I, ll. 203–206
Translations of the title often allude to similar expressions used in domestic works of literature: the French edition of the work is entitled Le Meilleur des mondes (The Best of All Worlds), an allusion to an expression used by the philosopher Gottfried Leibniz and satirised in Candide, Ou l'Optimisme by Voltaire (1759).
