so many more elements enter into this ‘mystery’ than are dreamed of by Plato and some other philosophers. Recent enquirers have indeed arrived at the conclusion that among primitive tribes there existed a community of wives as of property, and that the captive taken by the spear was the only wife or slave whom any man was permitted to call his own. The partial existence of such customs among some of the lower races of man, and the survival of peculiar ceremonies in the marriages of some civilized nations, are thought to furnish a proof of similar institutions having been once universal. There can be no question that the study of anthropology has considerably changed our views respecting the first appearance of man upon the earth. We know more about the aborigines of the world than formerly, but our increasing knowledge shows above all things how little we know. With all the helps which written monuments afford, we do but faintly realize the condition of man two thousand or three thousand years ago. Of what his condition was when removed to a distance 200,000 or 300,000 years, when the majority of mankind were lower and nearer the animals than any tribe now existing upon the earth, we cannot even entertain conjecture. Plato (Laws) and Aristotle (Metaph.) may have been more right than we imagine in supposing that some forms of civilisation were discovered and lost several times over. If we cannot argue that all barbarism is a degraded civilization, neither can we set any limits to the depth of degradation to which the human race may sink through war, disease, or isolation. And if we are to draw inferences about the origin of marriage from the practice of barbarous nations, we should also consider the remoter analogy of the animals. Many birds and animals, especially the carnivorous, have only one mate, and the love and care of offspring which seems to be natural is inconsistent with the primitive theory of marriage. If we go back to an imaginary state in which men were almost animals and the companions of them, we have as much right to argue from what is animal to what is human as from the barbarous to the civilized man. The record of animal life on the globe is fragmentary,—the connecting links are wanting and cannot be supplied; the record of social life is still more fragmentary and precarious. Even if we admit that our first ancestors had no such institution as marriage, still the stages by which men passed from outer barbarism to the comparative civilization of China, Assyria, and Greece, or even of the ancient Germans, are wholly unknown to us.
