These two elements, of freedom and civilization, always antagonist, have been in most ages hostile. The individual freedom of the North has been equivalent to barbarism, and from time to time has rolled down a destroying deluge over the South, almost sweeping away its civilization, and overwhelming in a common ruin arts, literature, and laws. On the other hand, civilization at the South has passed into luxury, has produced effeminacy, till individual freedom has been lost under grinding despotism. But in modern civilization a third element has been added, which has brought these two powers of Northern freedom and Southern culture into equipoise and harmony. This new element is Christianity, which develops, at the same time, the sense of personal responsibility, by teaching the individual destiny and worth of every soul, and also the mutual dependence and interlacing brotherhood of all human society. This Christian element in modern civilization saves it from the double danger of a relapse into barbarism on the one hand, and a too refined luxury on the other. The nations of Europe, to-day, which are the most advanced in civilization, literature, and art, are also the most deeply pervaded with the love of freedom; and the most civilized nations on the globe, instead of being the most effeminate, are also the most powerful. The Scandinavian people, destined to play so important a part in the history of the world, were, as we have said, a branch of the great Indo-European variety. We have seen that modern ethnology teaches that all the races which inhabit Europe, with some trifling exceptions, belong to one family, which originated in Central Asia. This has appeared and is proved by means of glossology, or the science of language. The closest resemblance exists between the seven linguistic families of Hindostan, Persia, Greece, Rome, Germany, the Kelts, and the Slavi; and it is a most striking fact of human history, that from the earliest period of recorded time down to the present day a powerful people, speaking a language belonging to one or other of these races, should have in a great measure swayed the destinies of the world.
