Jefferson entered the College of William & Mary in Williamsburg, Virginia, at age 16 and studied mathematics, metaphysics, and philosophy under Professor William Small. Under Small's tutelage, Jefferson encountered the ideas of the British Empiricists, including John Locke, Francis Bacon, and Isaac Newton. Small introduced Jefferson to George Wythe and Francis Fauquier. Small, Wythe, and Fauquier recognized Jefferson as a man of exceptional ability and included him in their inner circle, where he became a regular member of their Friday dinner parties where politics and philosophy were discussed. Jefferson later wrote that he "heard more common good sense, more rational & philosophical conversations than in all the rest of my life". During his first year at the college he was given more to parties and dancing and was not very frugal with his expenditures; during his second year, regretting that he had squandered away much time and money, he applied himself to fifteen hours of study a day. Jefferson improved his French and Greek and his skill at the violin. He graduated two years after starting in 1762. He read the law under Wythe's tutelage to obtain his law license while working as a law clerk in his office. He also read a wide variety of English classics and political works. Jefferson was well-read in a broad variety of subjects, which along with law and philosophy, included history, natural law, natural religion, ethics, and several areas in science, including agriculture. Overall, he drew very deeply on the philosophers. During the years of study under the watchful eye of Wythe, Jefferson authored a survey of his extensive readings in his "Commonplace Book". Wythe was so impressed with Jefferson that he would later bequeath his entire library to Jefferson.
