To conclude this introduction: my initiation, as I have confessed, was primarily an emotional one. My interest in Birth Control was awakened by experience. Research and investigation have followed. Our effort has been to raise our program from the plane of the emotional to the plane of the scientific. Any social progress, it is my belief, must purge itself of sentimentalism and pass through the crucible of science. We are willing to submit Birth Control to this test. It is part of the purpose of this book to appeal to the scientist for aid, to arouse that interest which will result in widespread research and investigation. I believe that my personal experience with this idea must be that of the race at large. We must temper our emotion and enthusiasm with the impersonal determination of science. We must unite in the task of creating an instrument of steel, strong but supple, if we are to triumph finally in the war for human emancipation. CHAPTER II: Conscripted Motherhood "Their poor, old ravaged and stiffened faces, their poor, old bodies dried up with ceaseless toil, their patient souls made me weep. They are our conscripts. They are the venerable ones whom we should reverence. All the mystery of womanhood seems incarnated in their ugly being--the Mothers! the Mothers! Ye are all one!" --From the Letters of William James Motherhood, which is not only the oldest but the most important profession in the world, has received few of the benefits of civilization. It is a curious fact that a civilization devoted to mother-worship, that publicly professes a worship of mother and child, should close its eyes to the appalling waste of human life and human energy resulting from those dire consequences of leaving the whole problem of child-bearing to chance and blind instinct. It would be untrue to say that among the civilized nations of the world to-day, the profession of motherhood remains in a barbarous state. The bitter truth is that motherhood, among the larger part of our population, does not rise to the level of the barbarous or the primitive. Conditions of life among the primitive tribes were rude enough and severe enough to prevent the unhealthy growth of sentimentality, and to discourage the irresponsible production of defective children. Moreover, there is ample evidence to indicate that even among the most primitive peoples the function of maternity was recognized as of primary and central importance to the community.
