In the history of ideas, the continuity thesis is the hypothesis that there was no radical discontinuity between the intellectual development of the Middle Ages and the developments in the Renaissance and early modern period. Thus the idea of an intellectual or scientific revolution following the Renaissance is, according to the continuity thesis, a myth. Some continuity theorists point to earlier intellectual revolutions occurring in the Middle Ages, usually referring to the European Renaissance of the 12th century as a sign of continuity. Despite the many points that have been brought up by proponents of the continuity thesis, a majority of scholars still support the traditional view of the Scientific Revolution occurring in the 16th and 17th centuries. Duhem The idea of a continuity, rather than contrast between medieval and modern thought, begins with Pierre Duhem, the French physicist and philosopher of science. It is set out in his ten volume work on the history of science, Le système du monde: histoire des doctrines cosmologiques de Platon à Copernic. Unlike many former historians such as Voltaire and Condorcet, who did not consider the Middle Ages to be of much intellectual importance , he tried to show that the Roman Catholic Church had helped foster the development of Western science. His work was prompted by his research into the origins of statics, where he encountered the works of medieval mathematicians and philosophers such as Nicole Oresme and Roger Bacon. He consequently came to regard them as the founders of modern science, their having in his view anticipated many of the discoveries of Galileo and later thinkers. Duhem concluded that "the mechanics and physics of which modern times are justifiably proud proceed, by an uninterrupted series of scarcely perceptible improvements, from doctrines professed in the heart of the medieval schools." Sarton Another notable supporter of the continuity thesis was George Sarton (1884–1956). In The History of Science and the New Humanism (1931), George Sarton put much stress on the historical continuity of science. Sarton further noted that the development of science stagnated during the Renaissance, due to Renaissance humanism putting more emphasis on form over fact, grammar over substance, and the adoration of ancient authorities over empirical investigation. As a result, he stated that science had to be introduced to Western culture twice: first in the 12th century during the Arabic–Latin translation movement, and again in the 17th century during what became
