Voltaire (1694–1778) was a French Enlightenment philosopher, writer, and satirist who championed reason, individual freedom, and separation of church and state. Known for his wit and criticism of religious dogma and political oppression, Voltaire’s works, such as Candide, played a pivotal role in promoting Enlightenment ideals. His advocacy for civil liberties, including freedom of speech and religious tolerance, influenced the development of modern democratic societies and had a lasting impact on the French Revolution and the advancement of human rights.
