Zadig is a work of philosophical fiction by the famous Enlightenment writer Voltaire. It is a delightful mix of political satire and insightful challenge of religious and metaphysical orthodoxy, with its main character undergoing a complete moral revolution while human life is presented as in the hands of a destiny beyond human control. Along with absolute stylistic mastery, Zadig provides insight into the nature of free will, in a story whose fast pace follows the highs and lows bestowed by Fortune on the hero.
