François-Marie Arouet (21 November 1694 30 May 1778), better known by the pen name Voltaire, was a French Enlightenment writer, essayist, deist and philosopher known for his wit, philosophical sport, and defense of civil liberties, including freedom of religion and the right to a fair trial. He was an outspoken supporter of social reform despite strict censorship laws in France and harsh penalties for those who broke them. A satirical polemicist, he frequently made use of his works to criticize Christian Church dogma and the French institutions of his day.
