In vain celibacy was made almost criminal. In vain celibates were declared incapable of inheriting, while fathers were offered every bribe, were preferred in appointments to office, were even given the choice seats at games; in the words of Tacitus, “not for that did marriage and children increase, for the advantages of childlessness prevailed.”[65] All that was done was to breed a race of informers, and to stimulate the lawyers to fresh chicane.[66] When wealth became force, the female might be as strong as the male; therefore she was emancipated. Through easy divorce she came to stand on an equality with the man in the marriage contract. She controlled her own property, because she could defend it; and as she had power, she exercised political privileges. In the third century Julia Domna, Julia Mamæa, Soæmias, and others, sat in the Senate, or conducted the administration. The evolution of this centralized society was as logical as every other work of nature. When force reached the stage where it expressed itself exclusively through money, the governing class ceased to be chosen because they were valiant or eloquent, artistic, learned, or devout, and were selected solely because they had the faculty of acquiring and keeping wealth. As long as the weak retained enough vitality to produce something which could be absorbed, this oligarchy was invincible; and for very many years after the native peasantry of Gaul and Italy had perished under the load, new blood injected from more tenacious races kept the dying civilization alive. The weakness of the monied class lay in their very power, for they not only killed the producer, but in the strength of their acquisitiveness they failed to propagate themselves. The State feigned to regard marriage as a debt, and yet the opulent families died out. In the reign of Augustus all but fifty of the patrician houses had become extinct, and subsequently the emperor seemed destined to remain the universal heir through bequests of the childless. With the peasantry the case was worse. By the second century barbarian labour had to be imported to till the fields, and even the barbarians lacked the tenacity of life necessary to endure the strain. They ceased to breed, and the population dwindled. Then, somewhat suddenly, the collapse came. With shrinking numbers, the sources of wealth ran dry, the revenue failed to pay the police, and on the efficiency of the police the life of this unwarlike civilization hung. In early ages every Roman had been a land-owner, and every land-owner had been a soldier, serving without pay. To fight had been as essential a part of life as to plough. But by the fourth century military service had become commercial; the legions were as purely an expression of money as the bureaucracy itself.
