The history of civilization is, curiously enough, the story of masculine brutality, self-indulgence, and vice. The history of the world also proves that woman's sphere has been to submit patiently and silently to injustice and imposition. _Practical eugenics is the first worthy effort in the history of all time to hold men and women responsible for their mode of living._ It is a mighty problem. There is no greater nor more difficult one to be solved. It has taken eons to bring men to the point of questioning their right to do as they please; it will take time to compel them to realize their disgrace and acknowledge their duty. When we consider that there are eighty thousand women condemned to professional moral degradation in the City of London, and that every so-called civilized city on the globe contributes its pro rata share to this army of potential mothers, we begin to appreciate the vastness of the task. Eugenics has already accomplished what no other movement has ever accomplished: it has created the spirit that gave birth to the thought of men's responsibility, and it has taught us that the female of the race has rights. We can now speak without fear; the light is no longer hidden. Women must realize, however, that they have contributed, and continue to contribute, to race degeneracy. We hear and read much about the double standard of morals. As long as woman are willing to marry their daughters to reformed rakes, providing they have money and social position, [xxviii] so long shall we have a double standard. So long as young society women go into hysterics over pedigreed dogs and horses and then marry men reeking in filthy unfitness for parenthood, mothers cannot expect any other standard of morals. So long as one marriage in twelve ends in divorce, the ethics of the female need enlightenment. We shall not get another standard of morals until women themselves demand it and insist on it. If they lend themselves to breaking down the conspiracy of silence, the women may solve the marriage problem by refusing to marry rakes. We need a more liberal construction of the intent of eugenics in order to clarify the obtuse minds so that its propaganda of education may be easily and justly comprehended. There is no field for speculation in the analysis of right living. It conforms to the law of cause and effect. It is positively concrete in substance. A recital of the life history of Jonathan Edwards, in comparison with that of the celebrated "Jukes" family, emphasises this assumption with a degree of positiveness that is tragic in its significance.
