I accepted one branch of this philosophy, but eugenics without birth control seemed to me a house built upon sands. It could not stand against the fu… - Margaret Sanger

The trouble with any effort of trying to divide humanity into the "fit" and the "unfit," is that we do not want, as H. G. Wells recently pointed out, to breed for uniformity but for variety. "We want statesmen and poets and musicians and philosophers and strong men and delicate men and brave men. The qualities of one would be the weaknesses of the other." We want, most of all, genius.
Proscription on Galtonian lines would tend to eliminate many of the great geniuses of the world who were not only "Bohemian," but actually and pathologically abnormal—men like Rousseau, Dostoevsky, Chopin, Poe, Schumann, Nietzsche, Comte, Guy de Maupassant,—and how many others? But such considerations should not lead us into error of concluding that such men were geniuses merely because they were pathological specimens, and that the only way to produce a genius is to breed disease and defect. It only emphasizes the dangers of external standards of "fit" and "unfit."
These limitations are more strikingly shown in the types of so-called "eugenic" legislation passed or proposed by certain enthusiasts. Regulation, compulsion and prohibitions affected and enacted by political bodies are the surest methods of driving the whole problem under-ground. As Havelock Ellis has pointed out, the absurdity and even hopelessness of effecting Eugenic improvement by placing on the statute books prohibitions of legal matrimony to certain classes of people, reveal the weakness of those Eugenists who minimize or undervalue the importance of environment as a determining factor. They affirm that heredity is everything and environment nothing, yet forget that it is precisely those who are most universally subject to bad environment who procreate most copiously, most recklessly and most disastrously.

These dangers inherent in the very idea of humanitarianism and altruism, dangers which have to-day produced their full harvest of human waste, of inequality and inefficiency, were fully recognized in the last century at the moment when such ideas were first put into practice.

While there are cases where even the law recognizes an abortion as justifiable if recommended by a physician, I assert that the hundreds of thousands of abortions performed in America each year are a disgrace to civilization.
