"A CIVILIZATION like that of China, in which the patriarchal family remained the corner-stone of society and the foundation of religion and ethics, has preserved its cultural traditions for more than 2,000 years without losing its vitality. In the classical cultures of the Mediterranean world, however, this was not the case. Here the patriarchal family failed to adapt itself to the urban conditions of the Hellenic civilization, and consequently the whole culture lost its stability. Conditions of life both in the Greek city state and in the Roman Empire favoured the man without a family who could devote his whole energies to the duties and pleasures of public life. Late marriages and small families became the rule, and men satisfied their sexual instincts by homosexuality or by relations with slaves and prostitutes. This aversion to marriage and the deliberate restriction of the family by the practice of infanticide and abortion was undoubtedly the main cause of the decline of ancient Greece, as Polybius pointed out in the second century B.C. And the same factors were equally powerful in the society of the Empire, where the citizen class even in the provinces was extraordinarily sterile and was recruited not by natural increase, but by the constant introduction of alien elements, above all from the servile class. Thus the ancient world lost its roots alike in the family and in the land and became prematurely withered.
"The reconstitution of Western civilization was due to the coming of Christianity and the re-establishment of the family on a new basis."
