Long before scientists learned to harness the power of atoms and build nuclear bombs, mankind had perfectly adequate weaponry for killing. Regular explosives were quite capable of blowing a building to small pieces and killing large numbers of people. Fear of those weapons was real, and everyone understood their awesome destructive power. Yet when even more powerful and brutish nuclear weaponry was finally born, and an arms race ensued, scientists and governments told North American parents that their children would be safe underneath their school desks if ever we were attacked. They told us to hide under kindling.
Early in the twentieth century, a movement that had been born some fifty years earlier really came into its own. It was the ‘science’ of eugenics. Most otherwise sane scientists, politicians, writers, social critics – just about everyone ‘intelligent’ – supported eugenics and loudly shouted down those few who argued against it. Eugenics flourished in the United States, where social and political activity was channeled into preventing the ‘inferior races’ and the ‘feeble-minded’ from reproducing. The movement was predicated on the idea that these inferior humans were out-breeding the intelligentsia and would eventually water down the human gene pool and turn us all into imbeciles. On that score, you must sometimes wonder if they were right.
While the eugenic movement predates the era when anyone really understood what a gene is, it was a scientific movement fully supported by government, industry, and educational authorities. With absolute certainty, universities taught the science of eugenics and governments made social policy based on a need to cull the herd. The movement reached its zenith in the 1930s when its focus was relocated to Germany. You know the rest.
