If you, like me, admire H. G. Wells’s futurist novels, you may not be aware of his advocacy of genocide and selective breeding in his “utopian” New Republic. He warned that “whole masses of human population are inferior in their claim upon the future”. “Base and servile types” would be euthanised, including criminals, insane, physically disabled or genetically diseased. “Swarms of black, and brown, and dirty-white, and yellow people, who do not meet the new needs of efficiency, will have to go”

[Anticipations, 1901]

” Man must go steeply up or down and the odds seem to be all in favour of his going down and out. If he goes up, then so great is the adaptation demanded of him that he must cease to be a man. Ordinary man is at the end of his tether. Only a small, highly adaptable minority of the species can possibly survive” .
