Explanation:

John Locke was an English philosopher and physician, considered one of the most influential thinkers of English empiricism and known as the "Father of Classical Liberalism." He was one of the first British empiricists. Influenced by the ideas of Francis Bacon, he made an important contribution to the theory of the social contract. His work greatly affected the development of epistemology and political philosophy. His writings influenced Voltaire and Rousseau, thinkers of the French Enlightenment, as well as American revolutionaries. His contributions to classical republicanism and liberal theory are reflected in the Declaration of Independence of the United States and the Bill of Rights of 1689.
