"The third group are those irresponsible and reckless ones having little regard for the consequences of their acts, or whose religious scruples prevent their exercising control over their numbers. Many of this group are diseased, feeble-minded, and are of the pauper element dependent upon the normal and fit members of society for their support. There is no doubt in the minds of all thinking people that the procreation of this group should be stopped."

“The basic freedom of the world is woman's freedom. A free race cannot be born of slave mothers. A woman enchained cannot choose but give a measure of that bondage to her sons and daughters. No woman can call herself free who does not own and control her body. No woman can call herself free until she can choose consciously whether she will or will not be a mother.”

“But during all the long years this matter has been discussed, advocated, refuted, the people themselves—poor people especially—were blindly, desperately practicing family limitation, just as they are practicing it today. To them birth control does not mean what it does to us. To them it has meant the most barbaric methods. It has meant the killing of babies—infanticide,—abortions,—in one crude way or another.”

“The most interesting incident of my life was some years ago when I was sitting beside a dying child's bed, watching the pulse and waiting for the crisis. It was about two o'clock in the morning. I started to take the pulse of the child and as I did so, I saw two bodies of the child - one slightly above the other exactly in the same position and an exact replica - except that it was not flesh but a substance more like cob-webs the color of smoke. I stood back and beheld this extraordinary phenomena and watched the upper body move majestically away in a horizontal position across the room and through the closed steel door. The physical body remained and was still breathing. Consciousness was never regained and an hour after, the little girl ceased to breathe.”

“Has knowledge of birth control, so carefully guarded and so secretly practiced by the women of the wealthy class – and so tenaciously withheld from the working women – brought them misery? Rather, has it not promoted greater happiness, greater freedom, greater prosperity and more harmony among them? The women who have this knowledge are the women who have been free to develop, free to enjoy in its best sense, and free to advance the interests of the community.”

“While it is necessary to point out the importance of "heredity" as a determining factor in human life, it is fatal to elevate it to the position of an absolute. As with environment, the concept of heredity derives its value and its meaning only in so far as it is embodied and made concrete in generations of living organisms. Environment and heredity are not antagonistic. Our problem is not that of "Nature vs. Nurture," but rather of Nature x Nurture, of heredity multiplied by environment, if we may express it thus. The Eugenist who overlooks the importance of environment as a determining factor in human life, is as short-sighted as the Socialist who neglects the biological nature of man. We cannot disentangle these two forces, except in theory. To the child in the womb, said Samuel Butler, the mother is "environment." She is, of course, likewise "heredity." The age-old discussion of "Nature vs. Nurture" has been threshed out time after time, usually fruitlessly, because of a failure to recognize the indivisibility of these biological factors. The opposition or antagonism between them is an artificial and academic one, having no basis in the living organism.”

“We are convinced that racial regeneration like individual regeneration, must come "from within." That is, it must be autonomous, self-directive, and not imposed from without. In other words, every potential parent, and especially every potential mother, must be brought to an acute realization of the primary and central importance of bringing children into this world. ... Not until the parents of the world are thus given control over their reproductive faculties will it ever be possible ... to improve the quality of the generations of the future, even to maintain civilization even at its present level. ... An idealistic code of sexual ethics, imposed from above, a set of rules devised by high-minded theorists who fail to take into account the living conditions and desires of the submerged masses, can never be of the slightest value in effecting any changes in the mores of the people.”
