The worlds which circle round the sun, or rather, the multitudinous systems of orbs which fill space, might pose a like inquiry. There was a time when _these_ which are now distinct worlds were confounded as a continuous nebula, a thin vapour of matter whirling round in one unchanging circle. In time, their motion became less uniform, vortices--as the word is--set in, smaller bodies of vaporous matter which, still obeying the universal movement, set up internal motions among themselves, and cooling, separated into separate orbs. How like is all this process to the history of nations! These, confounded once together in one unstable mass of wandering tribes, have in like manner separated from their nebulous brethren, and, setting up their internal vortices, have coalesced into nations. And yet as a system of planets, albeit with their own distinctive motions, do all revolve in one direction round one central force, so the different families of nations, which we may call the planets of a system, seem in like manner compelled by a power external to themselves in one particular course to play a particular part in the world’s history. The early stone-age Turanians, the Cushite civilizers of Egypt and Chaldæa, the Semitic people, may all be looked upon as different systems of nations, each with its mission to the human race. Thus, too, the Aryan people, after they had once become so separated as to lose all family remembrance, are found working together to accomplish an assigned destiny, migrating in every direction, and carrying with them everywhere the seeds of a higher civilization.
