Again, this force has tended to concentrate itself more and more in certain groups which we call 'civilised nations.' The literati of the last century were for ever in fear of a new conquest of the barbarians, but only because their imagination was overshadowed and frightened by the old conquests. A very little consideration would have shown them that, since the monopoly of military inventions by cultivated states, real and effective military power tends to confine itself to those states. The barbarians are no longer so much as vanquished competitors; they have ceased to compete at all. The military vices, too, of civilisation seem to decline just as its military strength augments. Somehow or other civilisation does not make men effeminate or unwarlike now as it once did. There is an improvement in our fibre--moral, if not physical. In ancient times city people could not be got to fight--seemingly could not fight; they lost their mental courage, perhaps their bodily nerve. But now-a-days in all countries the great cities could pour out multitudes wanting nothing but practice to make good soldiers, and abounding in bravery and vigour. This was so in America; it was so in Prussia; and it would be so in England too. The breed of ancient times was impaired for war by trade and luxury, but the modern breed is not so impaired.
A curious fact indicates the same thing probably, if not certainly. Savages waste away before modern civilisation; they seem to have held their ground before the ancient. There is no lament in any classical writer for the barbarians. The New Zealanders say that the land will depart from their children; the Australians are vanishing; the Tasmanians have vanished. If anything like this had happened in antiquity, the classical moralists would have been sure to muse over it; for it is just the large solemn kind of fact that suited them. On the contrary, in Gaul, in Spain, in Sicily--everywhere that we know of--the barbarian endured the contact of the Roman, and the Roman allied himself to the barbarian. Modern science explains the wasting away of savage men; it says that we have diseases which we can bear, though they cannot, and that they die away before them as our fatted and protected cattle died out before the rinderpest, which is innocuous, in comparison, to the hardy cattle of the Steppes. Savages in the first year of the Christian era were pretty much what they were in the 1800th; and if they stood the contact of ancient civilised men, and cannot stand ours, it follows that our race is presumably tougher than the ancient; for we have to bear, and do bear, the seeds of greater diseases than those the ancients carried with them. We may use, perhaps, the unvarying savage as a metre to gauge the vigour of the constitutions to whose contact he is exposed.
