Educated at Christ Church College, Oxford, he became (1660) a lecturer there in Greek, rhetoric, and philosophy. He studied medicine, and his acquaintance with scientific practice had a strong influence upon his philosophical thought and method. In 1666, Locke met Anthony Ashley Cooper, the future 1st earl of Shaftesbury, and soon became his friend, physician, and adviser. After 1667, Locke had minor diplomatic and civil posts, most of them through Shaftesbury. In 1675, after Shaftesbury had lost his offices, Locke left England for France, where he met French leaders in science and philosophy.
Returning to England in 1679, he soon retired to Oxford, where he stayed quietly until, suspected of radicalism by the government, he went to Holland and remained there several years (1683-89). In Holland he completed the famous Essay Concerning Human Understanding (1690), which was published in complete form after his return to England at the accession of William and Mary to the English throne. In the same year he published his Two Treatises on Civil Government; part of this work justifies the Glorious Revolution of 1688, but much of it was written earlier. His fame increased, and he became known in England and on the Continent as the leading philosopher of freedom.
In the Essay Concerning Human Understanding Locke examines the nature of the human mind and the process by which it knows the world. Repudiating the traditional doctrine of innate ideas, Locke believed that the mind is born blank, a tabula rasa upon which the world describes itself through the experience of the five senses. Knowledge arising from sensation is perfected by reflection, thus enabling humans to arrive at such ideas as space, time, and infinity.
Locke distinguished the primary qualities of things (e.g., solidity, extension, number) from their secondary qualities (e.g., color, sound). These latter qualities he held to be produced by the impact of the world on the sense organs. Behind this curtain of sensation the world itself is colorless and silent. Science is possible, Locke maintained, because the primary world affects the sense organs mechanically, thus producing ideas that faithfully represent reality. The clear, common-sense style of the Essay concealed many unexplored assumptions that the later empiricists George Berkeley and David Hume would contest, but the problems that Locke set forth have occupied philosophy in one way or another ever since.
Locke is most renowned for his political theory. Contradicting Thomas Hobbes, Locke believed that the original state of nature was happy and characterized by reason and tolerance. In that state all people were equal and independent, and none had a right to harm another's "life, health, liberty, or possessions." The state was formed by social contract because in the state of nature each was his own judge, and there was no protection against those who lived outside the law of nature. The state should be guided by natural law.
Rights of property are very important, because each person has a right to the product of his or her labor. Locke forecast the labor theory of value. The policy of governmental checks and balances, as delineated in the Constitution of the United States, was set down by Locke, as was the doctrine that revolution in some circumstances is not only a right but an obligation. At Shaftesbury's behest, he contributed to the Fundamental Constitutions for the Carolinas; the colony's proprietors, however, never implemented the document.
Locke based his ethical theories upon belief in the natural goodness of humanity. The inevitable pursuit of happiness and pleasure, when conducted rationally, leads to cooperation, and in the long run private happiness and the general welfare coincide. Immediate pleasures must give way to a prudent regard for ultimate good, including reward in the afterlife. He argued for broad religious freedom in three separate essays on toleration but excepted atheism and Roman Catholicism, which he felt should be legislated against as inimical to religion and the state. In his essay The Reasonableness of Christianity (1695), he emphasized the ethical aspect of Christianity against dogma.

John Locke (29 August 1632 – 28 October 1704) was an English philosopher. Locke is considered the first of the British Empiricists, but is equally important to social contract theory. His ideas had enormous influence on the development of epistemology and political philosophy, and he is widely regarded as one of the most influential Enlightenment thinkers, classical republicans, and contributors to liberal theory. His writings influenced Voltaire and Rousseau, many Scottish Enlightenment thinkers, as well as the American revolutionaries. This influence is reflected in the American Declaration of Independence.
Locke's theory of mind is often cited as the origin for modern conceptions of identity and "the self", figuring prominently in the later works of philosophers such as David Hume, Jean-Jacques Rousseau and Immanuel Kant. Locke was the first philosopher to define the self through a continuity of "consciousness." He also postulated that the mind was a "blank slate" or "tabula rasa"; that is, contrary to Cartesian or Christian philosophy, Locke maintained that people are born without innate ideas.
In 1647, Locke was sent to the prestigious Westminster School in London under the sponsorship of Alexander Popham, a member of Parliament and former commander of the younger Locke's father. After completing his studies there, he was admitted to Christ Church, Oxford. 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 English Royal Society, of which he eventually became a member.
Locke was awarded a bachelor's degree in 1656 and a master's degree in 1658. He obtained a bachelor of medicine in 1674, having studied medicine extensively during his time at Oxford and worked with such noted scientists and thinkers as Robert Boyle, Thomas Willis, Robert Hooke and Richard Lower. In 1666, he met Lord Anthony Ashley Cooper, 1st Earl of Shaftesbury, who had come to Oxford seeking treatment for a liver infection. Cooper was impressed with Locke and persuaded him to become part of his retinue.
Locke had been looking for a career and in 1667 moved into Shaftesbury's home at Exeter House in London, to serve as Lord Ashley's 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 the An Essay Concerning Human Understanding.
Locke's medical knowledge was put to the test when Shaftesbury's liver infection became life-threatening. Locke coordinated the advice of several physicians and was probably instrumental in persuading Shaftesbury to undergo an operation (then life-threatening itself) to remove the cyst. Shaftesbury survived and prospered, crediting Locke with saving his life.
It was in Shaftesbury's household, during 1671, that the meeting took place, described in the Epistle to the reader of the Essay, which was the genesis of what would later become Essay. Two extant Drafts still survive from this period. It was also during this time that Locke served as Secretary of the Board of Trade and Plantations and Secretary to the Lords and Proprietors of the Carolinas, helping to shape his ideas on international trade and economics.
Shaftesbury, as a founder of the Whig movement, exerted great influence on Locke's political ideas. Locke became involved in politics when Shaftesbury became Lord Chancellor in 1672. Following Shaftesbury's fall from favour in 1675, Locke spent some time travelling across France. 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. Locke wrote the Treatises to defend the Glorious Revolution of 1688, but also to counter the absolutist political philosophy of Sir Robert Filmer and Thomas Hobbes. Though Locke was associated with the influential Whigs, his ideas about natural rights and government are today considered quite revolutionary for that period in English history.
However, Locke fled to the Netherlands, Holland, in 1683, under strong suspicion of involvement in the Rye House Plot (though there is little evidence to suggest that he was directly involved in the scheme). In the Netherlands Locke had time to return to his writing, spending a great deal of time re-working the Essay and composing the Letter on Toleration. Locke did not return home until after the Glorious Revolution. Locke accompanied William of Orange's wife back to England in 1688. The bulk of Locke's publishing took place after his arrival back in England his aforementioned Essay Concerning Human Understanding, the Two Treatises of Civil Government and A Letter Concerning Toleration all appearing in quick succession upon his return from exile.
Locke's close friend Lady Masham invited him to join her at the Mashams' country house in Essex. Although his time there was marked by variable health from asthma attacks, he nevertheless became an intellectual hero of the Whigs. During this period he discussed matters with such figures as John Dryden and Isaac Newton.
He died in 28 October 1704, and is buried in the churchyard of the village of High Laver, east of Harlow in Essex, where he had lived in the household of Sir Francis Masham since 1691. Locke never married nor had children.
Events that happened during Locke's lifetime include the English Restoration, the Great Plague of London and the Great Fire of London. He did not quite see the Act of Union of 1707, though the thrones of England and Scotland were held by the same monarch throughout his lifetime. Constitutional monarchy and parliamentary democracy were in their infancy during Locke's time.
But Locke's influence may have been even more profound in the realm of epistemology. Locke redefined subjectivity, or self, and intellectual historians such as Charles Taylor and Jerrold Seigel argue that Locke's Essay Concerning Human Understanding (1690) marks the beginning of the modern conception of the self.
Locke believed that ownership of property is created by the application of labor. In addition, property precedes government and government cannot "dispose of the estates of the subjects arbitrarily." Karl Marx later critiqued Locke's theory of property in his social theory.
Locke's political theory was founded on social contract theory. Unlike Thomas Hobbes, Locke believed that human nature is characterized by reason and tolerance. Like Hobbes, Locke believed that human nature allowed men to be selfish. This is apparent with the introduction of currency. In a natural state all people were equal and independent, and everyone had a natural right to defend his “life, health, liberty, or possessions.” Like Hobbes Locke assumed that the sole right to defend in the state of nature was not enough, so people established a civil society to resume conflicts in civil way with a help from government in a state of society. However, Locke never refers to Hobbes by name and may instead have been responding to other writers of the day. Locke also advocated governmental separation of powers and believed that revolution is not only a right but an obligation in some circumstances. These ideas would come to have profound influence on the Constitution of the United States and its Declaration of Independence.
Locke argues that a country should seek a favorable balance of trade, lest it fall behind other countries and suffer a loss in its trade. Since the world money stock grows constantly, a country must constantly seek to enlarge its own stock. Locke develops his theory of foreign exchanges, in addition to commodity movements, there are also movements in country stock of money, and movements of capital determine exchange rates. The latter is less significant and less volatile than commodity movements. As for a country’s money stock, if it is large relative to that of other countries, it will cause the country’s exchange to rise above par, as an export balance would do.
He also prepares estimates of the cash requirements for different economic groups (landholders, laborers and brokers). In each group the cash requirements are closely related to the length of the pay period. He argues the brokers – middlemen – whose activities enlarge the monetary circuit and whose profits eat into the earnings of laborers and landholders, had a negative influence on both one's personal and the public economy that they supposedly contributed to.
In his Essay, Locke explains the gradual unfolding of this conscious mind. Arguing against both the Augustinian view of man as originally sinful and the Cartesian position, which holds that man innately knows basic logical propositions, Locke posits an "empty" mind, a tabula rasa, which is shaped by experience; sensations and reflections being the two sources of all our ideas. Locke's Some Thoughts Concerning Education is an outline on how to educate this mind: he expresses the belief that education maketh the man, or, more fundamentally, that the mind is an "empty cabinet", with the statement, "I think I may say that of all the men we meet with, nine parts of ten are what they are, good or evil, useful or not, by their education.
Locke also wrote that "the little and almost insensible impressions on our tender infancies have very important and lasting consequences. He argued that the "associations of ideas" that one makes when young are more important than those made later because they are the foundation of the self: they are, put differently, what first mark the tabula rasa. In his Essay, in which is introduced both of these concepts, Locke warns against, for example, letting "a foolish maid" convince a child that "goblins and sprites" are associated with the night for "darkness shall ever afterwards bring with it those frightful ideas, and they shall be so joined, that he can no more bear the one than the other.
"Associationism", as this theory would come to be called, exerted a powerful influence over eighteenth-century thought, particularly educational theory, as nearly every educational writer warned parents not to allow their children to develop negative associations. It also led to the development of psychology and other new disciplines with David Hartley's attempt to discover a biological mechanism for associationism in his Observations on Man (1749).
