Question: Richard Ithamar Aaron, was a philosopher, of which nationality, who became an authority on the work of John Locke?
Context: Liberalism, the belief in freedom and human rights, is historically associated with such thinkers as John Locke and Montesquieu.  It is a political movement which spans the better part of the last four centuries, though the use of the word "liberalism" to refer to a specific political doctrine did not occur until the 19th century.  The Glorious Revolution of 1688 in England laid the foundations for the development of the modern liberal state by constitutionally limiting the power of the monarch, affirming parliamentary supremacy, passing the Bill of Rights and establishing the principle of 'consent of the governed'.  The 1776 Declaration of Independence of the United States of America founded the nascent republic on liberal principles without the encumbrance of hereditary aristocracy; the declaration stated that "all men are created equal and endowed by their creator with certain unalienable rights, among these life, liberty, and the pursuit of happiness," echoing John Locke's phrase "life, liberty, and property".  A few years later, the French Revolution overthrew the hereditary aristocracy, with the slogan "liberty, equality, fraternity", and was the first state in history to grant universal male suffrage.  The Declaration of the Rights of Man and of the Citizen, first codified in 1789 in France, is a foundational document of both liberalism and human rights. Liberalisme: Politisk frihet fra John Locke til Amartya Sen (English: Liberalism: Political Freedom from John Locke to Amartya Sen ) is a 2009 Norwegian language anthology edited by Lars Svendsen.  The book focuses on the history of liberalism and libertarianism in general, and contains a sample of liberal thinkers from John Locke to Amartya Sen.  It was published by Universitetsforlaget with financial support from Civita and Fritt Ord.  The book received mixed reviews by critics. The John Locke Foundation (JLF) is a conservative think tank based in North Carolina.  The organization was founded in 1990 to work "for truth, for freedom, and for the future of North Carolina."  It is named after the philosopher John Locke, who was a primary contributor to classical liberalism.  JLF was co-founded by Art Pope, a North Carolina businessman active in politics.  Pope's family foundation provides most of the support for the center. John Locke is a fictional character played by Terry O'Quinn on the ABC television series "Lost".  He is named after English philosopher John Locke.  In 2007, O'Quinn won the Primetime Emmy Award for Outstanding Supporting Actor in a Drama Series for his portrayal of Locke. A Letter Concerning Toleration by John Locke was originally published in 1689.  Its initial publication was in Latin, though it was immediately translated into other languages.  Locke's work appeared amidst a fear that Catholicism might be taking over England, and responds to the problem of religion and government by proposing religious toleration as the answer.  This "letter" is addressed to an anonymous "Honored Sir": this was actually Locke's close friend Philipp van Limborch, who published it without Locke's knowledge. John Locke is a writer and novelist who was the eighth author—and first self-published author—to sell over one million eBooks on Amazon.com.  Locke is a "New York Times" best-selling author, and is best known for his Donovan Creed thriller series and Emmett Love Western series.  His works are self-published worldwide.  In the U.S., Locke's books are released through Amazon's Kindle Direct Publishing service.  Locke's books have been translated into over 29 languages. Innatism is a philosophical and epistemological doctrine that holds that the mind is born with ideas/knowledge, and that therefore the mind is not a "blank slate" at birth, as early empiricists such as John Locke claimed.  It asserts that not all knowledge is gained from experience and the senses.  Plato and Descartes are prominent philosophers in the development of innatism and the notion that the mind is already born with ideas, knowledge and beliefs.  Both philosophers emphasize that experiences are the key to unlocking this knowledge but not the source of the knowledge itself.  Essentially, no knowledge is derived exclusively from one's experiences as empiricists like John Locke suggested. Richard Ithamar Aaron (6 November 1901 – 29 March 1987) was a Welsh philosopher who became an authority on the work of John Locke. John Locke {'1': ", '2': ", '3': ", '4': "} ( ; 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, he 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, 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. John Locke's Of the Conduct of the Understanding describes how to think clearly and rationally.  It is a handbook for autodidacts.  It complements Locke's "Some Thoughts Concerning Education" which explains how to educate children.  The text was first published in 1706, two years after Locke's death, as part of Peter King's "Posthumous Works of John Locke".
