109. Greek degeneracy. The decline of the Greeks in the three centuries before our era is so great and sudden that it is very difficult to understand it. The best estimate of the population of the Peloponnesus in the second century B.C. puts it at one hundred and nine per square mile.135 Yet the population was emigrating, and population was restricted. A pair would have but one or two children. The cities were empty and the land was uncultivated.136 There was neither war nor pestilence to account for this. It may be that the land was exhausted. There must have been a loss of economic power so that labor was unrewarded. The mores all sank together. There can be no achievement in the struggle for existence without an adequate force. Our civilization is built on steam. The Greek and Roman civilization was built on slavery, that is, on an aggregation of human power. The result produced was, at first, very great, but the exploitation of men entailed other consequences besides quantities of useful products. It was these consequences which issued in the mores, for, in a society built on slavery as the form of productive industry, all the mores, obeying the strain of consistency, must conform to that as the chief of the folkways. It was at the beginning of the empire that the Romans began to breed slaves because wars no longer brought in new supplies.137 Sex, vice, laziness, decline of energy and enterprise, cowardice, and contempt for labor were consequences of slavery, for the free.138 The system operated, in both the classical states, as a selection against the superior elements in the population. This effect was intensified by the political system. The city became an arena of political struggle for the goods of life which it was a shame to work for. Tyrannies and democracies alternated with each other, but both alike used massacre and proscription, and both thought it policy to get rid of troublesome persons, that is, of those who had convictions and had courage to avow them. Every able man became a victim of terrorism, exerted by idle market-place loafers. The abuse of democratic methods by those-who-had-not to plunder those-who-had must also have had much to do with the decline of economic power, and with the general decline of joy in life and creative energy. It would also make marriage and children a great and hopeless burden. Abortion and sex vice both directly and indirectly lessened population, by undermining the power of reproduction, while their effect to destroy all virile virtues could not fail to be exerted.139 It was another symptom of disease in the mores that the number of males in the Roman empire greatly exceeded the number of females.140 The Roman system used up women.
110. Sparta. The case of Sparta is especially interesting because the Spartan mores were generally admired and envied in the fourth century B.C. They were very artificial and arbitrary. They developed into a catastrophe. The population declined to such a point that it was like group suicide. The nation incased itself in fossilized mores and extremest conservatism, by which its own energies were crushed. The institutions produced consequences which were grotesque compared with what had been expected from them.141
111. Optimism of prosperity. "I apprehend that the key to the joyful character of the antique religions known to us [in western Asia] lies in the fact that they took their shape in communities that were progressive and, on the whole, prosperous." Weak groups were exterminated. Those which survived "had all the self-confidence and elasticity that are engendered by success in the struggle of life." "The religious gladness of the Semites tended to assume an orgiastic character and become a sort of intoxication of the senses, in which anxiety and sorrow were drowned for the moment."142
112. Antagonism between an individual and the mores. The case of dissent from the mores, which was considered above (sec. 100), is the case in which the individual voluntarily sets himself in antagonism to the mores of the society. There are cases in which the individual finds himself in involuntary antagonism to the mores of the society, or of some subgroup to which he belongs. If a man passes from one class to another, his acts show the contrast between the mores in which he was bred and those in which he finds himself. The satirists have made fun of the parvenu for centuries. His mistakes and misfortunes reveal the nature of the mores, their power over the individual, their pertinacity against later influences, the confusion in character produced by changing them, and the grip of habit which appears both in the persistence of old mores and the weakness of new ones. Every emigrant is forced to change his mores. He loses the sustaining help of use and wont. He has to acquire a new outfit of it. The traveler also experiences the change from life in one set of mores to life in another. The experience gives him the best power to criticise his native mores from a standpoint outside of them. In the North American colonies white children were often stolen by Indians and brought up by them in their ways. Whether they would later, if opportunity offered, return to white society and white mores, or would prefer to remain with the Indians, seems to have depended on the age at which they were captured. Missionaries have often taken men of low civilization out of the society in which they were born, have educated them, and taught them white men's mores. If a single clear and indisputable case could be adduced in which such a person was restored to his own people and did not revert to their mode of life, it would be a very important contribution to ethnology. We are forced to believe that, if a baby born in New England was taken to China and given to a Chinese family to rear and educate, he would become a Chinaman in all which belongs to the mores, that is to say, in his character, conduct, and code of life.
113. Antagonism of earlier and later mores. When, in the course of time, changes occur in the mores, the men of a later generation find themselves in antagonism to the mores of their ancestors. In the Homeric poems cases are to be found of disapproval by a later generation of the mores of a former one. The same is true of the tragedies of the fifth century in respect to the mythology and heroism in Homer. The punishment of Melantheus, the unfaithful goatherd, was savage in the extreme, but when Eurykleia exulted over the dead suitors, Ulysses told her that it was a cruel sin to rejoice over slain enemies.143 In the Iliad boastful shouts over the dead are frequent. In the Odyssey such shouts are forbidden.144 Homer thinks that it was unseemly for Achilles to drag the corpse of Hector behind his chariot.145 He says that the gods disapproved, which is the mystic way of describing a change in the mores.146 He also disapproves of the sacrifice of Trojan youths on the pyre of Patroclus.147 It was proposed to Pausanias that he should
