As an advocate of birth control I wish ... to point out that the unbalance between the birth rate of the 'unfit' and the 'fit,' admittedly the greatest present menace to civilization, can never be rectified by the inauguration of a cradle competition between these two classes. In this matter, the example of the inferior classes, the fertility of the feeble-minded, the mentally defective, the poverty-stricken classes, should not be held up for emulation.... On the contrary, the most urgent problem today is how to limit and discourage the over-fertility of the mentally and physically defective.
Margaret SangerNo despot ever flung forth his legions to die in foreign conquest, no privilege-ruled nation ever erupted across its borders, to lock in death embrace with another, but behind them loomed the driving power of a population too large for its boundaries and its natural resources.
Margaret SangerBy all means, there should be no children when either mother or father suffers from such diseases as tuberculosis, gonorrhea, syphilis, cancer, epilepsy, insanity, drunkenness and mental disorders. In the case of the mother, heart disease, kidney trouble and pelvic deformities are also a serious bar to childbearing No more children should be born when the parents, though healthy themselves, find that their children are physically or mentally defective.
Margaret SangerKnowledge of birth control is essentially moral. Its general, though prudent, practice must lead to a higher individuality and ultimately to a cleaner race.
