Question: In what country did Cameron accept a chair of philosophy? Passage 1:For the next three hundred years, Scotland was directly governed by the Parliament of Great Britain and the subsequent Parliament of the United Kingdom, both seated at Westminster, and the lack of a Parliament of Scotland remained an important element in Scottish national identity. Suggestions for a 'devolved' Parliament were made before 1914, but were shelved due to the outbreak of the First World War. A sharp rise in nationalism in Scotland during the late 1960s fuelled demands for some form of home rule or complete independence, and in 1969 prompted the incumbent Labour government of Harold Wilson to set up the Kilbrandon Commission to consider the British constitution. One of the principal objectives of the commission was to examine ways of enabling more self-government for Scotland, within the unitary state of the United Kingdom. Kilbrandon published his report in 1973 recommending the establishment of a directly elected Scottish Assembly to legislate for the majority of domestic Scottish affairs.
Passage 2:Mikhail Sumarokov-Elston was born on in 1893 to Count Nicholai Felixovich Sumarokov-Elston reserve Lieutenant of the Cavalry Regiment and Countess Sofia Mikhaylovna Koskul. He was the great-great-great-great-grandson of poet Alexander Sumarokov and the Great Great Grandson of Field Marshal Mikhail Kutuzov. He was the nephew of tennis player Count Pavel Sumarokov-Elston, who was his first coach and doubles partner, grandson of Count-General Felix Sumarokov-Elston, Governor of Kuban Oblast, and cousin of the infamous Prince Felix Yussupov, who later became known as one of the collaborators who conspired to kill Grigori Rasputin, cult leader and mentor of Empress consort of Russia Alexandra. Felix provided his own palace for the murder spot and also shot Rasputin once before murdering him with the help of his accomplices. Mikhail had a sister called Elena and a brother Nicholas. At the age of twelve he had a surgery on his right hand, which as a result was rendered unsuitable for tennis and he later switched to left-hand play. First he moved to Dresden and was trained by Kurt Bergmann and George K. Logie. In 1906 he entered the second-class tournament of the Bad Homburg Championships, where he defeated Jack Hillyard amongst many to claim his first title. With this he set a record of being the youngest winner ever at the time in the history of the tournament. In 1908 his father and brother died within two weeks of each other. He moved back to his homeland and graduated first at the Annenschule then at the Law Faculty of the St. Petersburg University.
Passage 3:Cameron was born at Glasgow and received his early education in his native city. After having taught Greek in the university for twelve months, he removed to Bordeaux, where he was soon appointed a regent in the college of Bergerac. He did not remain long at Bordeaux, but accepted the offer of a chair of philosophy at the Academy of Sedan, where he passed two years. He then returned to Bordeaux, and in the beginning of 1604 he was nominated one of the students of divinity who were maintained, at the expense of the church, and who for the period of four years were at liberty to prosecute their studies in any Protestant seminary. During this period he acted as tutor to the two sons of the chancellor of Navarre. They spent one year at Paris, and two at Geneva, whence they removed to Heidelberg. In this university, on 4 April 1608, he gave a public proof of his ability by maintaining a series of theses, De triplici Dei cum Homine Foedere, which were printed among his works. The same year he was recalled to Bordeaux, where he was appointed the colleague of Dr Gilbert Primrose; and when Francis Gomarus was removed to Leiden, Cameron, in 1618, was appointed professor of divinity at the Academy of Saumur, the principal seminary of the French Protestants.
