It seems that feeblemindedness is a very hereditary quality, and science isn't able to overcome it. No operation has been discovered for introducing brains into the head of a child who didn't start with them. And the child grows up with, say, a nine-year brain in a thirty-year body, and becomes an easy tool for any criminal he meets. Our prisons are one-third full of feeble-minded convicts. Society ought to segregate them on feeble-minded farms, where they can earn their livings in peaceful menial pursuits, and not have children. Then in a generation or so we might be able to wipe them out.英文原著 · 《Dear Enemy》

On school work he does altogether much better. He writes a good hand, reads fairly well, and promptly does a sum in long division. He claims to have reached the 6th grade. One difficulty in testing him was his prevailing lethargy. We constantly had to fight this by encouragement. Once he insisted he must give up the work because he had not had a smoke for an hour or so. Altogether, including his irregularities, we could not call him lower than poor in ability, possibly subnormal. He did not come within the limits of the feebleminded group.英文原著 · 《Pathology of Lying》
The learned professor assumes that while a long-continued war had strengthened rather than weakened the instinct of paternal devotion, it had also dulled other humanitarian instincts, and raised to the first magnitude the law of the survival of the fittest, with the result that when the exodus took place the strong, the intelligent, and the cunning, together with their offspring, crossed the waters of the Channel or the North Sea to the continent, leaving in unhappy England only the helpless inmates of asylums for the feebleminded and insane.英文原著 · 《The Lost Continent》
