Excerpts from Books and Wikipedia
""In 1147, Matilda’s fourteen-year-old son Henry excused himself from his studies in Western Francia (his tutor was the well-regarded philosopher William of Conches, author of a masterwork intended to reconcile Greek natural philosophy with Christian orthodoxy) and headed to England. [Bauer: Renaissance World, p. 76-9] [William of Conches] was born in Conches, Normandy. His teaching activity extended from c. 1120 to 1154, and about the year 1145 he became the tutor of Henry Plantagenet. It is possible, but uncertain, that he was teaching at Chartres before that. Warned by a friend of the danger implied in his Platonic realism as he applied it to theology, he took up the study of Islamic philosophy and physical science. . . . William devoted much attention to cosmology and psychology. Having been a student of Bernard of Chartres, he shows the characteristic Humanism, tendency towards Platonism, and taste for natural science which distinguish the "Chartrains". He is one of the first of the medieval Christian philosophers to take advantage of Islamic physical and physiological lore, to which he had access in the translations by Constantine the African."
