John Locke, English rationalist philosopher of the seventeenth century, is best known for his monumental An Essay Concerning Human Understanding, which was to furnish basic premises, not only for the coming Age of Reason and the deistic theology upon which many of its ideas were based, but also for the incipient Industrial Revolution with its rising entrepreneur class, and for political revolution in America. John Locke
Locke was the son of a Puritan attorney of Somerset, also named John Locke, who had served as a captain in the Parliamentary army under Oliver Cromwell and who lost a considerable part of his fortune at the time of the Restoration in 1660. This financial setback was an important factor in the life of young Locke, for it meant that he was unable to lead the life of quiet contemplation he desired. Instead, he was forced to make a career of public office and to tie himself unwillingly to the changing circumstances of a patron. Because of this forced dependence on political patronage, his important works were not written until the final quarter of his life.
His first opportunity for a life of contemplation was denied because of his religious convictions. Although he had received his master’s degree from Oxford in 1658 and held minor positions at the university for a period of six years, permanent tenure was denied him because of his refusal to take holy orders; he had by then abandoned Puritanism and taken a stand against state religion, as he shows in A Letter Concerning Toleration. True to his principles, he left Oxford rather than submit to governmental policies of required conformity.
Having received an appointment as secretary to Sir Walter Vane, Locke traveled with him on a mission to Brandenburg in 1665. Finding public activity inimical to philosophical thought, he refused to accompany Vane on a second mission. Instead, he took his small patrimony and pursued the study of chemistry and medicine. Although political influence kept him from receiving a medical degree, his scientific genius soon won him both the respect of his colleagues and a fellowship in the Royal Society in 1668. He also gained the patronage of Anthony Ashley Cooper, soon to become the first earl of Shaftesbury, whose household physician he became. He also served as tutor and personal secretary and, following Shaftesbury’s rise to the chancellorship in 1672, was appointed government secretary of presentations at a salary of five hundred pounds. In 1673 he became president of the Board of Trade.
These lucrative posts were lost with Shaftesbury’s first fall from power, but a pension of one hundred pounds a year left Locke free to take up his scholarly activities in Holland. Still he was to be harassed by politics. Shaftesbury was now branded a traitor and Locke became a fugitive from extradition proceedings, unable to return to England until after the revolution of 1688 and the accession of William of Orange. Then Locke was restored to office with the position of commissioner of appeals. His famous An Essay Concerning Human Understanding appeared two years later. During the remaining fourteen years of his life, spent mostly in the household of Sir Francis Masham, he was free to continue the work that was to influence so strongly the whole course of Western thought.
