A numerous, or even excessive population is undoubtedly an essential element of political power in a state; but it is not the only, nor in any respect, the principal symptom or indication of the civilization of a country. It is only in regard to civilization that the population of China deserves our consideration. Although in these latter times, when Europe by her political ascendency over the other parts of the world has proved the high pre-eminence of her arts and civilization; England and Russia have become the immediate neighbours of China towards the north and west; still these territorial relations affect not the rest of Europe; and China, when we leave out of consideration its very important commerce, cannot certainly be accounted a political power in the general system. Even in ancient, as well as in modern times, China never figured in the history of Western Asia or Europe, and had no connection whatever with their inhabitants; but this great country has ever stood apart, like a world within itself, in the remote, unknown Eastern Asia. Hence the earlier writers on universal history have taken little or no notice of this great Empire, shut out as it was from the confined horizon of their views. And this was natural, when we consider that the conquests and expeditions of the Asiatic nations were considered by these writers as subjects of the greatest weight and importance. No conquerors have ever marched from China into Western Asia, like Xerxes, for instance, who passed from the interior of Persia to Athens; or Alexander the Great, who extended his victorious march from his small paternal province of Macedon, to beyond the Indus, and almost to the borders of the Ganges, though the latter river, he was in despite of all his efforts, unable to reach. But the great victorious expeditions have proceeded not from China, but from central Asia, and the nations of Tartary, who have invaded China itself; though in these invasions the manners, mind, and civilization of the Chinese have evinced their power, as their Tartar conquerors, in the earliest as in the latest times, have after a few generations, invariably conformed to the manners and civilization of the conquered nation, and become more or less Chinese.
