John Locke, English physician and philosopher (died 1704)

John Locke was an English philosopher and physician, widely regarded as one of the most influential of the Enlightenment thinkers and commonly known as the "father of liberalism". His important works include A Letter Concerning Toleration (1689), Two Treatises of Government (1689/90), both published anonymously, and An Essay Concerning Human Understanding (1689/90). His writing on toleration contends that religion is a matter for the individual and that the churches are voluntary associations, ruling out religious coercion and uniformity; these lead to the idea of separation of church and state. His Two Treatises on Government argues for government based on the consent of the governed and the right to revolt against tyrannous government which has lost consent. The Two Treatises are believed to have influenced the language that Thomas Jefferson chose in his drafting the July 1776 Declaration of Independence during the War of American Independence.
