Social Darwinism in the Gilded Age

Charles Darwin’s On the Origin of Species (1859) is one of the most important books in the annals of both science and history. In Origin and in his subsequent writing Darwin offered a revolutionary scientific theory: the process of evolution through natural selection.$^1$start superscript, 1, end superscript

In short, natural selection means that plants and animals evolve over time in nature as new species arise from spontaneous mutations at the point of reproduction and battle with other plants and animals to get food, avoid being killed, and have offspring. Darwin pointed to fossil records, among other evidence, in support of his theory.

Soon, some sociologists and others were taking up words and ideas which Darwin had used to describe the biological world, and they were adopting them to their own ideas and theories about the human social world. In the late nineteenth and early twentieth centuries, these Social Darwinists took up the language of evolution to frame an understanding of the growing gulf between the rich and the poor as well as the many differences between cultures all over the world.

The explanation they arrived at was that businessmen and others who were economically and socially successful were so because they were biologically and socially “naturally” the fittest. Conversely, they reasoned that the poor were “naturally” weak and unfit and it would be an error to allow the weak of the species to continue to breed. They believed that the dictum “survival of the fittest” (a term coined not by Charles Darwin but by sociologist Herbert Spencer) meant that only the fittest should survive.$^2$squared

Unlike Darwin, these sociologists and others were not biologists. They were adapting and corrupting Darwin’s language for their own social, economic, and political explanations. While Darwin’s theory remains a cornerstone of modern biology to this day, the views of the Social Darwinists are no longer accepted, as they were based on an erroneous interpretation of the theory of evolution.

Social Darwinian language like this extended into theories of race and racism, eugenics, the claimed national superiority of one people over another, and immigration law.

Many sociologists and political theorists turned to Social Darwinism to argue against government programs to aid the poor, as they believed that poverty was the result of natural inferiority, which should be bred out of the human population. Herbert Spencer gave as an example a young woman from upstate New York named Margaret, whom he described as a “gutter-child.” Because government aid had kept her alive, Margaret had, as Spencer wrote, “proved to be the prolific mother” of two hundred descendants who were “idiots, imbeciles, drunkards, lunatics, paupers, and prostitutes.” Spencer concluded by asking, “Was it kindness or cruelty which, generation after generation, enabled these to multiply and become an increasing curse to the society around them?”$^3$cubed

These ideas inspired the eugenics movement of the nineteenth and twentieth centuries, which sought to improve the health and intelligence of the human race by sterilizing individuals it deemed "feeble-minded" or otherwise "unfit." Eugenic sterilizations, which disproportionately targeted women, minorities, and immigrants, continued in the United States until the 1970s.$^4$start superscript, 4, end superscript

The pernicious beliefs of Social Darwinism also shaped Americans' relationship with peoples of other nations. As a massive number of immigrants came to the United States during the Second Industrial Revolution, white, Anglo-Saxon Americans viewed these newcomers—who differed from earlier immigrants in that they were less likely to speak English and more likely to be Catholic or Jewish rather than Protestant—with disdain. Many whites believed that these new immigrants, who hailed from Eastern or Southern Europe, were racially inferior and consequently "less evolved" than immigrants from England, Ireland, or Germany.$^5$start superscript, 5, end superscript

Similarly, Social Darwinism was used as a justification for American imperialism in Cuba, Puerto Rico, and the Philippines following the Spanish-American War, as many adherents of imperialism argued that it was the duty of white Americans to bring civilization to "backwards" peoples.

During and after World War II, the arguments of Social Darwinists and eugenicists lost popularity in the United States due to their association with Nazi racial propaganda. Modern biological science has completely discredited the theory of Social Darwinism.
