All this may be granted as having been true in the past. And many, reassured by this frank admission, will ask, if it is so clear that the subjection of woman was useful, that this evil-working, monstrous sexuo-economic relation was after all of racial advantage, how we know that it is time to change. Principally, because we are changing. Social development is not caused by the promulgators of theories and by the writers of books. When Rousseau wrote of equality, free France was being born,—the spirit of the times thrilled through the human mind; and those who had ears to hear heard, those who had pens to write wrote. The condition of chattel slavery, working to its natural end, roused Garrison and Phillips and Harriet Beecher Stowe. They did not make the movement. The period of women’s economic dependence is drawing to a close, because its racial usefulness is wearing out. We have already reached a stage of human relation where we feel the strength of social duty pull against the sex-ties that have been for so long the only ties that we have recognized. The common consciousness of humanity, the sense of social need and social duty, is making itself felt in both men and women. The time has come when we are open to deeper and wider impulses than the sex-instinct; the social instincts are strong enough to come into full use at last. This is shown by the twin struggle that convulses the world to-day,—in sex and economics,—the “woman’s movement” and the “labor movement.” Neither name is wholly correct. Both make a class issue of what is in truth a social issue, a question involving every human interest. But the women naturally feel most the growing healthful pain of their position. They personally revolt, and think it is they who are most to be benefited. Similarly, since the “laboring classes” feel most the growing healthful pain of their position, they as naturally revolt under the same conviction. Sociologically, these conditions, which some find so painful and alarming, mean but one thing,—the increase of social consciousness. The progress of social organization has produced a corresponding degree of individualization, which has reached at last even to women,—even to the lowest grade of unskilled labor. This higher degree of individualization means a sharp personal consciousness of the evils of a situation hitherto little felt. With this higher growth of individual consciousness, and forming a part of it, comes the commensurate growth of social consciousness. We have grown to care for one another.
