diagnosed so much more completely the complex malady of contemporary society were intensely disliked by the superficial theorists of the neo-Marxian School.

The gospel of Marx had, however, been too long and too thoroughly inculcated into the minds of millions of workers in Europe, to be discarded. It is a flattering doctrine, since it teaches the laborer that all the fault is with someone else, that he is the victim of circumstances, and not even a partner in the creation of his own and his child's misery. Not without significance was the additional discovery that I made. I found that the Marxian influence tended to lead workers to believe that, irrespective of the health of the poor mothers, the earning capacity of the wage-earning fathers, or the upbringing of the children, increase of the proletarian family was a benefit, not a detriment to the revolutionary movement. The greater the number of hungry mouths, the emptier the stomachs, the more quickly would the "Class War" be precipitated. The greater the increase in population among the proletariat, the greater the incentive to revolution. This may not be sound Marxian theory; but it is the manner in which it is popularly accepted. It is the popular belief, wherever the Marxian influence is strong. This I found especially in England and Scotland. In speaking to groups of dockworkers on strike in Glasgow, and before the communist and co-operative guilds throughout England, I discovered a prevailing opposition to the recognition of sex as a factor in the perpetuation of poverty. The leaders and theorists were immovable in their opposition. But when once I succeeded in breaking through the surface opposition of the rank and file of the workers, I found that they were willing to recognize the power of this neglected factor in their lives.

So central, so fundamental in the life of every man and woman is this problem that they need be taught no elaborate or imposing theory to explain their troubles. To approach their problems by the avenue of sex and reproduction is to reveal at once their fundamental relations to the whole economic and biological structure of society. Their interest is immediately and completely awakened. But always, as I soon discovered, the ideas and habits of thought of these submerged masses have been formed through the Press, the Church, through political institutions, all of which had built up a conspiracy of silence around a subject that is of no less vital importance than that of Hunger. A great wall separates the masses from those imperative truths that must be known and flung wide if civilization is to be saved. As currently constituted, Church, Press, Education seem to-day organized to exploit the ignorance and the prejudices of the masses, rather than to light their way to self-salvation.

Such was the situation in 1914, when I returned to America, determined, since the exclusively masculine point of view had dominated too long, that the other half of the truth should be made known. The Birth Control movement was launched because it was in this form that the whole relation of woman and child—eternal emblem of the future of society—could be more effectively dramatized. The amazing growth of this movement dates from the moment when in my home a small group organized the first Birth Control League. Since then we have been criticized for our choice of the term "Birth Control" to express the idea of modern scientific contraception. I have yet to hear any criticism of this term that is not based upon some false and hypocritical sense of modesty, or that does not arise out of a semi-prurient misunderstanding of its aim. On the other hand: nothing better expresses the idea of purposive, responsible, and self-directed guidance of the reproductive powers.

Those critics who condemn Birth Control as a negative, destructive idea, concerned only with self-gratification, might profitably open the nearest dictionary for a definition of "control." There they would discover that the verb "control" means to exercise a directing, guiding, or restraining influence;—to direct, to regulate, to counteract. Control is guidance, direction, foresight. It implies intelligence, forethought and responsibility. They will find in the Standard Dictionary a quotation from Lecky to the effect that, "The greatest of all evils in politics is power without control." In what phase of life is not "power without control" an evil? Birth Control, therefore, means not merely the limitation of births, but the application of intelligent guidance over the reproductive power. It means the substitution of reason and intelligence for the blind play of instinct.

The term "Birth Control" had the immense practical advantage of compressing into two short words the answer to the inarticulate demands of millions of men and women in all countries. At the time this slogan was formulated, I had not yet come to the complete realization of the great truth that had been thus crystallized. It was the response to the overwhelming, heart-breaking appeals that came by every mail for aid and advice, which revealed a great truth that lay dormant, a truth that seemed to spring into full vitality almost over night—that could never again be crushed to earth!

Nor could I then have realized the number and the power of the enemies who were to be aroused into activity by this idea. So completely was I dominated by this conviction of the efficacy of "control," that I could not until later realize the extent of the sacrifices that were to be exacted of me and of those who supported my campaign. The very idea of Birth Control resurrected the spirit of the witch-hunters of Salem. Could they have usurped the power, they would have burned us at the stake. Lacking that power, they used the weapon of suppression, and invoked medieval statutes to send us to jail. These tactics had an effect the very opposite to that intended. They demonstrated the vitality of the idea of Birth Control, and acted as counter-irritant on the actively intelligent sections of the American community. Nor was the interest aroused confined merely to America. The neo-Malthusian movement in Great Britain with its history of undaunted bravery, came to our support; and I had the comfort of knowing that the finest minds of England did not hesitate a moment in the expression of their sympathy and support.

In America, on the other hand, I found from the beginning until very recently that the so-called intellectuals exhibited a curious and almost inexplicable reticence in supporting Birth Control. They even hesitated to voice any public protest against the campaign to crush us which was inaugurated and sustained by the most reactionary and sinister forces in American life. It was not inertia or any lack of interest on the part of the masses that stood in our way. It was the indifference of the intellectual leaders.

Writers, teachers, ministers, editors, who form a class dictating, if not creating, public opinion, are, in this country, singularly inhibited or unconscious of their true function in the community. One of their first duties, it is certain, should be to champion the constitutional right of free speech and free press, to welcome any idea that tends to awaken the critical attention of the great American public. But those who reveal themselves as fully cognizant of this public duty are in the minority, and must possess more than average courage to survive the enmity such an attitude provokes.

One of the chief aims of the present volume is to stimulate American intellectuals to abandon the mental habits which prevent them from seeing human nature as a whole, instead of as something that can be pigeonholed into various compartments or classes. Birth Control affords an approach to the study of humanity because it cuts through the limitations of current methods. It is economic, biological, psychological and spiritual in its aspects. It awakens the vision of mankind moving and changing, of humanity growing and developing, coming to fruition, of a race creative, flowering into beautiful expression
