John Locke (August 29, 1632 – October 28, 1704) was an English philosopher. In epistemology, Locke has often been classified as a British Empiricist, along with David Hume and George Berkeley. He is equally important as a social contract theorist, as he developed an alternative to the Hobbesian state of nature and argued a government could only be legitimate if it received the consent of the governed through a social contract and protected the natural rights of life, liberty, and property.
