“Birth control itself, often denounced as a violation of natural law, is nothing more or less than the facilitation of the process of weeding out the unfit, of preventing the birth of defectives or of those who will become defectives. So, in compliance with nature’s working plan, we must permit womanhood its full development before we can expect of it efficient motherhood. If we are to make racial progress, this development of womanhood must precede motherhood in every individual woman.”

Responses in a publicity questionnaire on Lord of the Flies from the American publishers, as quoted in Who Rules?: Introduction to the Study of Politics (1971) by Dick W. Simpson, p. 16
Context: The theme is an attempt to trace the defects of society back to the defects of human nature. The moral is that the shape of a society must depend on the ethical nature of the individual and not on any political system however apparently logical or respectable. The whole book is symbolic in nature except the rescue in the end where adult life appears, dignified and capable, but in reality enmeshed in the same evil as the symbolic life of the children on the island. The officer, having interrupted a man-hunt, prepares to take the children off the island in a cruiser which will presently be hunting its enemy in the same implacable way. And who will rescue the adult and his cruiser?
