Voltaire, pen name of François-Marie Arouet, was a tireless writer, playwright and polemicist. He used irony as a weapon against religious fanaticism, censorship and the abuses of the Church and monarchy, even being jailed and exiled. His tales, like Candide, and his campaigns for victims of injustice made him the face of the French Enlightenment.
