The distinction between ancient and modern history, therefore, is no mere accident, nor yet a mere matter of chronological convenience. What is called modern history is in reality the formation of a new cycle of culture, connected at several epochs of its development with the perishing or perished civilization of the mediterranean states, as that was connected with the primitive civilization of the Indo-Germanic stock, but destined, like that earlier cycle, to traverse an orbit of its own. It too is destined to experience in full measure the vicissitudes of national weal and woe, period of growth, of full vigour, and of age, the blessedness of creative effort, in religion, polity, and art, the comfort of enjoying the material and intellectual acquisitions it has won, perhaps also, some day, the decay of productive power in the satiety of contentment with the goal attained. But that goal too will only be temporary: the grandest system of civilization has its orbit, and may complete its course; but not so the human race, to which, even when it seems to have attained its goal, the old task is ever set anew with a wider range and with a deeper meaning.
