_Demop_. It is a good thing you reminded me of it. Migration was the source of the evil, and Christianity the dam on which it broke. Christianity was the means of controlling and taming those raw, wild hordes who were washed in by the flood of migration. The savage man must first of all learn to kneel, to venerate, and to obey; it is only after that, that he can be civilised. This was done in Ireland by St. Patrick, in Germany by Winifred the Saxon, who was a genuine Boniface. It was migration of nations, this last movement of Asiatic races towards Europe, followed only by their fruitless attempts under Attila, Gengis Khan, and Timur, and, as a comic after-piece, by the gipsies: it was migration of nations which swept away the humanity of the ancients. Christianity was the very principle which worked against this savagery, just as later, through the whole of the Middle Age, the Church and its hierarchy were extremely necessary to place a limit to the savagery and barbarism of those lords of violence, the princes and knights: it was the ice-breaker of this mighty flood. Still, the general aim of Christianity is not so much to make this life pleasant as to make us worthy of a better. It looks beyond this span of time, this fleeting dream, in order to lead us to eternal salvation. Its tendency is ethical in the highest sense of the word, a tendency which had hitherto been unknown in Europe; as I have already pointed out to you by comparing the morality and religion of the ancients with those of Christianity.
