" The bulk of the population of every country is persuaded that all marriage customs other than its own are immoral, and that those who combat this view do so only in order to justify their own loose lives. In India, the remarriage of widows is traditionally regarded as a thing too horrible to contemplate. In Catholic countries divorce is thought very wicked, but some failure of conjugal fidelity is tolerated, at least in men. In America divorce is easy, but extra-conjugal relations are condemned with the utmost severity. Mohammedans believe in polygamy, which we think degrading. All these differing opinions are held with extreme vehemence, and very cruel persecutions are inflicted upon those who contravene them. Yet no one in any of the various countries makes the slightest attempt to show that the custom of his own country contributes more to human happiness than the custom of others. "
