Under the stimulus of the sexuo-economic relation, one civilization after another has climbed up and fallen down in weary succession. It remains for us to develope a newer, better form of sex-relation and of economic relation therewith, and so to grasp the fruits of all previous civilizations, and grow on to the beautiful results of higher ones. The true and lasting social progress, beyond that which we have yet made, is based on a spirit of inter-human love, not merely the inter-sexual; and it requires an economic machinery organized and functioned for human needs, not sexual ones. The sexuo-economic relation drives man up to where he can become fully human. It deepens and developes the human soul until it is able to conceive and fulfil the larger social uses in which our further life must find expression. But, unless the human soul sees these new forces, feels them, gives way to them in loyal service, it fails to reach the level from which all further progress must proceed, and falls back. Again and again society has so risen, so failed to grasp new duties, so fallen back. To-day it will not so fall again, because the social consciousness is at last so vital a force in both men and women that we feel clearly that our human life cannot be fully lived on sex-lines only. We are so far individualized, so far socialized, that men can work without the tearing spur of exaggerated sex-stimulus, work for some one besides mate and young; and women can love and serve without the slavery of economic dependence,—love better and serve more. Sex-stimulus begins and ends in individuals. The social spirit is a larger thing, a better thing, and brings with it a larger, nobler life than we could ever know on a sex-basis solely. Moreover, it should be distinctly understood, as it is already widely and vaguely felt, that the higher development of social life following the economic independence of women makes possible a higher sex-life than has ever yet been known. As fast as the human individual rises in social progress to a certain degree of development, so fast this primitive form of sex-union chafes and drags: it is felt to be unsatisfying and injurious. This is a marked feature in modern life. The long, sure, upward trend of the human race toward monogamous marriage is no longer helped, but hindered by the economic side of the relation. The best marriage is between the best individuals; and the best individuals of both sexes to-day are increasingly injured by the economic basis of our marriage, which produces and maintains those qualities in men and women and their resultant industrial conditions which make marriage more difficult and precarious every day.
