But if it is possible to catch a glimpse of the end of female servitude and of the antagonism of the sexes and to conceive for the human species an era of incomparable bodily and mental progress, brought about by women and men of a high development in muscle and brain, it is impossible to foresee the sexual relations of free and equal women and men who will not be united nor separated by sordid material interests and by the gross ethics engendered by such interests. But if we may judge by the present and the past, men, in whom the genetic passion is more violent and more continuous than in women—the same phenomenon is observed in the males and females of the whole animal series—will be obliged to exhibit their physical and intellectual qualities to win their sweethearts. Sexual selection, which, as Darwin has shown, fulfilled an important role in the development of the animal species and which, with rare exceptions, has ceased to play this part in the Indo-European races for about three thousand years, will again become one of the most active factors in the perfecting of the human race. Motherhood and love will permit women to regain the higher position which she occupied in primitive societies, the memory of which has been preserved by the legends and myths of the ancient religions. FOOTNOTES: [34] The dowry has played an important role in the history of woman: at the beginning of the patriarchal period the husband buys her from her father, who has to refund her purchase price if for any cause whatever he repudiates her and sends her back to her family; later this purchase price is returned to him and constitutes her dowry, which her relatives are accustomed to double. From the moment when the wife enters into her husband's house with a dowry, she ceases to be a slave whom he may dismiss, sell and kill. The dowry, which in Rome and Athens became a legal charge upon the property of the husband, was, in case of her repudiation or divorce, to be restored to her in preference to any creditor. "No pleasure is derived from the riches which a woman brings into the household," says a fragment of Euripides, "they only serve to render divorce difficult." The comic authors ridiculed the husbands, who in fear of a suit over the dowry, fell into dependence upon the wife. A character in Plautus says to a husband who is talking against his wife, "You accepted the money of her dowry, you sold your authority—imperium." The wealthy Roman matrons carried their insolence to such a point that they did not trust the management of their dowry to their husbands, they gave it over to the stewards, who sometimes fulfilled with them another service, as the evil-speaking Martial states.
