According to the conventional view,the Middle Ages interrupted the scientific tradition of the ancient Greek and Roman times,so it is known as "Dark Ages" of science.Until the Italian Renaissance,referring to a large number of literature,Boethius who was prominent during the 4-5th centuries reconstructed the classical Greek based on the seven liberal arts,especially on the Aristotle's writings.Seven liberal arts then became a basic course in Christian schools,which greatly influenced the whole Christian understandings of god,particularly the theological argument.All these achievements have accumulated knowledge of the middle ages and promoted development of scientific revolution.In summary,Boethius has contributed greatly to the western scientific thought,which continued from the ancient Greek to the Middle Ages.Therefore,understanding Boethius is the premise and necessary condition for understanding the relation between Western science and religion.
