Margaret Sanger,
The Case for Birth Control: A Supplementary Brief and Statement of Facts
“ As we realize our responsibility we see that our new power of control is not merely for the end of limiting the quantity of human life, perhaps for a selfish object, but for the high end of improving its quality. It is in our power not only to generate life, but, if we will, to regenerate life. If we realize that possibility, and if we understand how the course of civilization has now brought it within our grasp, we have reached the heart of our problem. Our greatest foe, apart from indifference, is ignorance. ”
