John Locke Quotes

English philosopher and physician1632–1704 10 quotes

John Locke was an English philosopher and physician, widely regarded as one of the most influential Enlightenment thinkers and commonly known as the "father of liberalism." His important works include A Letter Concerning Toleration, Two Treatises of Government and An Essay Concerning Human Understanding.

His writing on toleration holds that religion is a matter for the individual and that churches are voluntary associations, ruling out religious coercion. His Two Treatises argue for government based on the consent of the governed and for the right to revolt against a tyrannous government that has lost that consent. The Two Treatises are believed to have influenced the language Thomas Jefferson chose when drafting the Declaration of Independence. An Essay Concerning Human Understanding is his most quoted work in our library.
