=Why past movements have failed.=--This is the Social Evil as we have found it in the past and as it is to-day, together with the fundamental causes that are back of it. Movements have sprung up during past centuries to stamp it out or at least to limit and control it. Rulers from Moses to Charlemagne have attempted to deal with the problems which it presents. These efforts in the past have failed largely because they sought reform through dealing with the women of shame only and thus was recognized and fostered one of the principal causes of the evil itself. =Why the modern movement is more effective.=--During the past sixty years there has developed the modern purity movement which has sought relief from the ravages of vice through a careful study of the evil and the application of such principles and remedies as would meet the situation effectively. This movement has been very rapid in growth not only in Europe and America but in all civilized countries. Even Japan has its book, “The Social Evil in Japan,” which not only reveals conditions there but also gives an account of the various organizations that are endeavoring to suppress public vice, and appeals for such legislation and education as will forever make the old régime impossible. While space will not permit us to treat historically of the origin of this movement or even to mention briefly those who founded it, we desire here to record our profound admiration for the early workers in this great cause. The “conspiracy of silence” was then in full operation. The faithful men and women who first stepped out from the beaten paths and espoused the cause of the “fallen” girl, were far more brave than he who faces midst the excitement of battle the cannon’s mouth. These pioneer men and women whose hearts had been wrung by the atrocities practiced upon the victims of vice, the utter despair in homes disrupted, and the agony of lives diseased and ruined, were socially ostracized, they were brought before courts, churches were closed to them, friends deserted them, mobs awaited them, all because they chose to set the slaves of vice free and to proclaim the truth. But still they were true, laboring faithfully on until to-day no movement for the uplift of society has a more general following and devoted leaders. All honor to the pioneers in the purity movement!
