But after the whole economic system has been re-adjusted and perfected and equalized, after we have the minimum wage, and the single tax, and industrial democracy, and every man gets what he produces, and economic pressure has been as scientifically adjusted as the atmospheres in a submarine torpedo boat, there is always the great law of the contrariety of things to be reckoned with, according to which the more carefully planned the event, the less it resembles the original conception. The human vision is so weak, and the great circle of life so prodigious! The solution will come, if it ever comes at all, by slow, patient, laborious, drudging study, far from the midnight session of the legislature, far from the ear and the pencil of the eager reporter, far from the platform of the sweating revivalist, far from the head office of the police. Our fondly perused pornography might expose the whole of the underworld to the light of day, the general assembly might enact successive revisions of the revised statutes for a hundred years, we might develop the most superb police organization in all history, achieving the apotheosis of the Puritan ideal with a dictagraph in every bedroom and closet in the town, and it all would be of no avail. The study must survey the whole field of social and domestic relations, until the vast mystery of life is understood, and the relation between its wide antitheses established as Tolstoy presents them in his story of the poor mother who took her daughter to the public house in the village, and the rich mother who, at the same time, took her daughter to the court at St. Petersburg. It will be found perhaps in the long run, for which so few are ever willing to remain, that the eradicable causes of prostitution are due to involuntary poverty, and the awful task is to get involuntary poverty out of the world. It is a task which has all the tremendous difficulties of constructive social labor and it is as deliberate as evolution itself. And even if it is ever accomplished, there will remain a residuum in the problem inhering in the mysteries of sex, concerning which even the wisest and most devoted of our scientists will confess they know very little as yet and have not much to tell us that will do us any good.
