„Woman must have her freedom; the fundamental freedom of choosing whether or not she shall be a mother and how many children she will have. Regardless of what man's attitude may be, that problem is hers; and before it can be his, it is hers alone. She goes through the vale of death alone, each time a babe is born. As it is the right neither of man nor the state to coerce her into this ordeal, so it is her right to decide whether she will endure it. That right to decide imposes upon her the duty of clearing the way to knowledge by which she may make and carry out the decision. Birth control is woman's problem. The quicker she accepts it as hers and hers alone, the quicker will society respect motherhood. The quicker, too, will the world be made a fit place for her children to live.“
