RUNNING DETAILS ON THE TWO MOVEMENTS IN THE INTELLECTUAL HISTORY OF SCIENCE AND IDEAS

A long tradition concerning the causes of the planetary movements existed as to the movements on the earth: the so called problem de motu locali. Starting from late middle Ages many criticisms were carried out against the Aristotelian doctrine of natural and violent motions. A well accredited and historically coherent theory to explain the movement and the change of movement was the medieval theory of impetus substantially developed by Jean Buridan (ca. 1300–ca. 1360) and by Nicolas d'Oresme (1320? 1325?–1382) on the basis of ideas that came back to John Philoponus (490–570).
