This is the natural death of human societies. Sometimes they expire gently and almost imperceptibly; oftener with a convulsion and a crash. I shall attempt to explain my meaning by a familiar simile. A mansion is built which in all respects suits the taste and wants of the owner. Succeeding generations find it too small, too dark, or otherwise ill adapted to their purposes. Respect for their progenitor, and family association, prevent, at first, very extensive changes, still each one makes some; and as these associations grow fainter, the changes become more radical, until at last nothing of the old house remains. But if it had previously passed into the hands of a stranger, who had none of these associations to venerate and respect, he would probably have pulled it down at once and built another. An empire, then, falls, when the vitalizing principle which gave it birth is exhausted; when its parts are connected by none but artificial ties, and artificial ties are all those which unite races possessed of different instincts. This idea is expressed in the beautiful image of the inspired prophet, when he tells the mighty king that great truth, which so many refuse to believe, that all earthly kingdoms must perish until "the God of Heaven set up a kingdom which shall never be destroyed."[25] "Thou, O king, sawest, and behold a great image. This great image, whose brightness was excellent, stood before thee, and the form thereof was terrible. This image's head was of fine gold, his breast and his arms of silver, his belly and his thighs of brass, his legs of iron, his feet part of iron and part of clay. Thou sawest till that a stone was cut without hands, which smote the image upon his feet that were of iron and clay, and brake them to pieces. Then was the iron, the clay, the brass, the silver, and the gold, broken to pieces together, and became like the chaff of the summer threshing-floors; and the wind carried them away, that no place was found for them."[26] I have now illustrated, to the best of my abilities, several of the most important propositions of Mr. Gobineau, and attempted to sustain them by arguments and examples different from those used by the author. For a more perfect exposition I must refer the reader to the body of the work. My purpose was humbly to clear away such obstacles as the author has left in the path, and remove difficulties that escaped his notice. The task which I have set myself, would, however, be far from accomplished, were I to pass over what I consider a serious error on his part, in silence and without an effort at emendation. Civilization, says Mr. Gobineau, arises from the combined action and mutual reaction of man's moral aspirations, and the pressure of his material wants. This, in a general sense, is obviously true. But let us see the practical application. I shall endeavor to give a concise abstract of his views, and then to point out where and why he errs.
