John LockeJohn Locke (; 29 August 1632 – 28 October 1704) was an English philosopher and physician, widely regarded as one of the most influential of Enlightenment thinkers and commonly known as the "Father of Liberalism". Considered one of the first of the British empiricists, following the tradition of Sir 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. 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.
Locke's theory of mind is often cited as the origin of modern conceptions of ''identity'' and the ''self'', figuring prominently in the work of later philosophers such as Jean-Jacques Rousseau, David Hume, and Immanuel Kant. Locke was the first to define the ''self'' through a continuity of consciousness. 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''. Demonstrating the ideology of science in his observations, whereby something must be capable of being tested repeatedly and that nothing is exempt from being disproved, Locke stated that "whatever I write, as soon as I discover it not to be true, my hand shall be the forwardest to throw it into the fire". Such is one example of Locke's belief in empiricism. Provided by Wikipedia
