It thus happens that savage peoples largely base their often admirable enforcement of asceticism not on the practical grounds that would justify it, but on religious grounds that with the growth of intelligence fall into discredit.[71] Even, however, when the scrupulous observances of savages, whether in sexual or in non-sexual matters, are without any obviously sound basis it cannot be said that they are entirely useless if they tend to encourage self-control and the sense of reverence.[72] The would-be intelligent and practical peoples who cast aside primitive observances because they seem baseless or even ridiculous, need a still finer practical sense and still greater intelligence in order to realize that, though the reasons for the observances have been wrong, yet the observances themselves may have been necessary methods of attaining personal and social efficiency. It constantly happens in the course of civilization that we have to revive old observances and furnish them with new reasons. In considering the moral quality of chastity among savages, we must carefully separate that chastity which among semi-primitive peoples is exclusively imposed upon women. This has no moral quality whatever, for it is not exercised as a useful discipline, but merely enforced in order to heighten the economic and erotic value of the women. Many authorities believe that the regard for women as property furnishes the true reason for the widespread insistence on virginity in brides. Thus A.B. Ellis, speaking of the West Coast of Africa (_Yoruba-Speaking Peoples_, pp. 183 _et seq._), says that girls of good class are betrothed as mere children, and are carefully guarded from men, while girls of lower class are seldom betrothed, and may lead any life they choose. "In this custom of infant or child betrothals we probably find the key to that curious regard for ante-nuptial chastity found not only among the tribes of the Gold and Slave Coasts, but also among many other uncivilized peoples in different parts of the world." In a very different part of the world, in Northern Siberia, "the Yakuts," Sieroshevski states (_Journal Anthropological Institute_, Jan.-June, 1901, p. 96), "see nothing immoral in illicit love, providing only that nobody suffers material loss by it. It is true that parents will scold a daughter if her conduct threatens to deprive them of their gain from the bride-price; but if once they have lost hope of marrying her off, or if the bride-price has been spent, they manifest complete indifference to her conduct. Maidens who no longer expect marriage are not restrained at all, if they observe decorum it is only out of respect to custom." Westermarck (_History of Human Marriage_, pp. 123 et seq.) also shows the connection between the high estimates of virginity and the
