Like any man, Tesla was far from perfect and sometimes had very warped ideas about how the world should operate. One of Tesla’s most disturbing ideas was his belief in using eugenics to purify the human race. In the 1930s, Tesla expressed his belief that the forced sterilization of criminals and the mentally ill — which was occurring in some European countries (most disturbingly Nazi Germany) and in many states in the U.S. — wasn’t going far enough. He believed that by the year 2100 eugenics would be “universally established” as a system of weeding out undesirable people from the population.
The February 9, 1935 issue of Liberty magazine includes many other fascinating predictions by Tesla for the future of humanity, which we’ll no doubt look at in the weeks ahead. But for the time being I’ve transcribed only the eugenics portion of Tesla’s predictions below, to remind us that we should be cautious when making gods of men:
The year 2100 will see eugenics universally established. In past ages, the law governing the survival of the fittest roughly weeded out the less desirable strains. Then man’s new sense of pity began to interfere with the ruthless workings of nature. As a result, we continue to keep alive and to breed the unfit. The only method compatible with our notions of civilization and the race is to prevent the breeding of the unfit by sterilization and the deliberate guidance of the mating instinct. Several European countries and a number of states of the American Union sterilize the criminal and the insane. This is not sufficient. The trend of opinion among eugenists is that we must make marriage more difficult. Certainly no one who is not a desirable parent should be permitted to produce progeny. A century from now it will no more occur to a normal person to mate with a person eugenically unfit than to marry a habitual criminal.
The ideas behind eugenics would become substantially less popular after World War II, for obvious reasons. I doubt that Tesla understood the scope of the atrocities that were being committed in Europe (and at the hands of the California eugenics movement) at the time. But again, his ideas were clear: the world should be rid of so-called undesirables. However unpleasant the idea of eugenics is to reasonable people on its surface, this notion seems particularly strange coming from a man like Tesla, whose own mental illnesses would have likely put him in the “undesirable” category under any authoritarian regime.
