John Locke (/lɒk/; 29 August 1632 (O.S.) – 28 October 1704 (O.S.))[11] 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".[12][13][14] Considered one of the first of the British empiricists, following the tradition of Francis Bacon, Locke is equally important to social contract theory. His work greatly affected the development of epistemology and political philosophy. His writings influenced Voltaire and Jean-Jacques Rousseau, and many Scottish Enlightenment thinkers, as well as the American Revolutionaries. His contributions to classical republicanism and liberal theory are reflected in the United States Declaration of Independence.[15] Internationally, Locke's political-legal principles continue to have a profound influence on the theory and practice of limited representative government and the protection of basic rights and freedoms under the rule of law.[16]

Locke's philosophy of mind is often cited as the origin of modern conceptions of personal identity and the psychology of self, figuring prominently in the work of later philosophers, such as Rousseau, David Hume, and Immanuel Kant. He postulated that, at birth, the mind was a blank slate, or tabula rasa. Contrary to Cartesian philosophy based on pre-existing concepts, he maintained that we are born without innate ideas, and that knowledge is instead determined only by experience derived from sense perception, a concept now known as empiricism.[17] Locke is often credited for describing private property as a natural right, arguing that when a person—metaphorically—mixes their labour with nature, resources can be removed from the common state of nature.[18][19]

Early life Locke was born on 29 August 1632, in a small thatched cottage by the church in Wrington, Somerset, about 12 miles (19 km) from Bristol. He was baptised the same day, as both of his parents were Puritans. Locke's father, also named John, was an attorney who served as clerk to the Justices of the Peace in Chew Magna,[20] and as a captain of cavalry for the Parliamentarian forces during the early part of the English Civil War. His mother was Agnes Keene. Soon after Locke's birth, the family moved to the market town of Pensford, about seven miles south of Bristol, where Locke grew up in a rural Tudor house in Belluton.

In 1647, Locke was sent to the prestigious Westminster School in London under the sponsorship of Alexander Popham, a member of Parliament and John Sr.'s former commander. At the age of 16 he was at school just half a mile away from the execution of Charles I; however, the boys were not allowed to go and watch. After completing studies at Westminster, he was admitted to Christ Church, Oxford, in the autumn of 1652 at the age of 20. The dean of the college at the time was John Owen, vice-chancellor of the university. Although a capable student, Locke was irritated by the undergraduate curriculum of the time. He found the works of modern philosophers, such as René Descartes, more interesting than the classical material taught at the university. Through his friend Richard Lower, whom he knew from the Westminster School, Locke was introduced to medicine and the experimental philosophy being pursued at other universities and in the Royal Society, of which he eventually became a member.[21]

Locke was awarded a bachelor's degree in February 1656 and a master's degree in June 1658.[1] He obtained a bachelor of medicine in February 1675,[22] having studied the subject extensively during his time at Oxford. In addition to Lower, he worked with such noted scientists and thinkers as Robert Boyle, Thomas Willis, and Robert Hooke. In 1666, he met Anthony Ashley Cooper, Lord Ashley, who had come to Oxford seeking treatment for a liver infection. Ashley was impressed with Locke and persuaded him to become part of his retinue. At Oxford, he was exposed to the writings of Islamic scholars, such as Ibn Tufayl's Hayy ibn Yaqdhan translated by Edward Pococke, who influenced his perspectives on philosophy and tabula rasa.[23][24][25][26]

Career Work Locke had been looking for a career and in 1667, moved into Ashley's home at Exeter House in London, to serve as his personal physician. In London, Locke resumed his medical studies under the tutelage of Thomas Sydenham. Sydenham had a major effect on Locke's natural philosophical thinking—an effect that would become evident in An Essay Concerning Human Understanding. Locke's medical knowledge was put to the test when Ashley's liver infection became life-threatening. Locke coordinated the advice of several physicians and was probably instrumental in persuading Ashley to undergo surgery (then life-threatening in itself) to remove the cyst. Ashley survived and prospered, crediting Locke with saving his life. During this time, Locke served as Secretary of the Board of Trade and Plantations and Secretary to the Lords Proprietors of Carolina, which helped to shape his ideas on international trade and economics.[27]

Ashley, as a founder of the Whig movement, exerted great influence on Locke's political ideas. Locke became involved in politics when Ashley became Lord Chancellor in 1672 (Ashley being created 1st Earl of Shaftesbury in 1673). Following Shaftesbury's fall from favour in 1675, Locke spent some time travelling across France as a tutor and medical attendant to Caleb Banks.[28] He returned to England in 1679 when Shaftesbury's political fortunes took a brief positive turn. Around this time, most likely at Shaftesbury's prompting, Locke composed the bulk of the Two Treatises of Government. While it was once thought that Locke wrote the Treatises to defend the Glorious Revolution of 1688, recent scholarship has shown that the work was composed well before this date.[29] The work is now viewed as a more general argument against absolute monarchy (particularly as espoused by Robert Filmer and Thomas Hobbes) and for individual consent as the basis of political legitimacy. Although Locke was associated with the influential Whigs, his ideas about natural rights and government are considered quite revolutionary for that period in English history.
