Except this was no accident. The Fabians, Sidney and Beatrice Webb and their ilk were not attracted to eugenics because they briefly forgot their leftwing principles. The harder truth is that they were drawn to eugenics for what were then good, leftwing reasons.
They believed in science and progress, and nothing was more cutting edge and modern than social Darwinism. Man now had the ability to intervene in his own evolution. Instead of natural selection and the law of the jungle, there would be planned selection. And what could be more socialist than planning, the Fabian faith that the gentlemen in Whitehall really did know best? If the state was going to plan the production of motor cars in the national interest, why should it not do the same for the production of babies? The aim was to do what was best for society, and society would clearly be better off if there were more of the strong to carry fewer of the weak.
What was missing was any value placed on individual freedom, even the most basic freedom of a human being to have a child. The middle class and privileged felt quite ready to remove that right from those they deemed unworthy of it.
And it\’s hardly unusual to have people arguing the primacy of society over individual freedom these days, is it?
