"Neither an enlightened philosophy, nor all the political wisdom of Rome, nor even the faith and virtue of the Christians availed against the incorrigible tradition of antiquity. Something was wanted, beyond all the gifts of reflection and experience — a faculty of self government and self control, developed like its language in the fibre of a nation, and growing with its growth. This vital element, which many centuries of warfare, of anarchy, of oppression, had extinguished in the countries that were still draped in the pomp of ancient civilization, was deposited on the soil of Christendom by the fertilising stream of migration that overthrew the empire of the West."
