“ The trend of recent historical research leads one even to doubt the validity of the very conception of any definite medieval period. The evolution of modern European society has been continuous. Progress has not been uniform. There was much retrogression with the intrusion of new barbarian races; but from their absorption by the 10th century until the 20th there is not a century in which some notable gain was not made towards the attainments of modern civilization. ”
