great neglected tundras of humanity. Then too, and not before, will the 

 economic basis of society be such as to allow a truly social control over 

 differential fertility. 



That imminently impending society, ordering its processes consciously 

 for the common good, assures every one economic plenty, takes away a 

 large part of the burden of the children from the shoulders of the individual 

 couple, and especially from the woman, and so makes it possible for them to 

 decide by considerations of the interests of the future generations, and of 

 the race as a whole, rather than of themselves, how many and what children 

 to have. Along with other debris, the cobwebs of superstition and taboo 

 will be swept clean away from the whole subject of sex and reproduction, 

 so as to make possible more real research, and more thoroughly rational 

 practices in these so important activities of man. The possibilities of the 

 future eugenics under these conditions are unlimited and inspiring. It is 

 up to us, if we want eugenics that functions, to work for it in the only way 

 now practicable, by first turning our hand to help throw over the incubus 

 of the old, outworn society.
