As Karl Pearson has recently said:
The great problem is whether limitation has not begun at the wrong end. If a nation is to be strong, there must be wastage; the reckless and diseased must not be in a condition to multiply like the strong and able. At present the strong and able refrain from bringing into the world those who might render it harder for the weak to multiply. They apparently prefer that the weak—too often artificially maintained in workhouse, institute, and asylum—shall pass in and out, multiply and inherit the land. It is not race-suicide; it is degeneracy of type. What is needed is a national awakening, a sense of national duties, and the primary duty of women to raise strong and healthy children.
