1694 – 1778
Voltaire (François-Marie Arouet, 1694–1778) was a French Enlightenment philosopher, satirist, and polemicist whose prolific output made him one of the most influential critics of religious intolerance and political tyranny in the early modern period. He championed civil liberties, freedom of expression, and the separation of church and state, opposing the institutional power of the Catholic Church while maintaining a deist theology. His caustic wit and philosophical rigor shaped Enlightenment skepticism toward revealed religion and ecclesiastical authority.
