Social degeneration
This article deals with the social-philosophical meaning of degeneration. For other meanings associated with degeneration, please see degeneracy.
The idea of degeneration had a huge influence on science, art and politics from the 1850s to the 1950s.
Georges-Louis Leclerc, Comte de Buffon (1707-1788) was the first to define "degeneration" as a Theory of nature. Buffon incorrectly argued that entire species "degenerated," becoming sterile, weaker, or smaller due to a harsh climates.
In the 1850s French doctor Bénédict Morel argued more vigorously that certain groups of people were degenerating, going backwards in terms of evolution so each generation became weaker and weaker. This was based on pre-Darwinian ideas of evolution, especially those of Jean-Baptiste Lamarck, who argued that acquired characteristics (drug habits, perversions, etc.) could be inherited. This is not true, as a matter of genetics.
A whole biological explanation for social problems was developed. Max Nordau's 1890s bestseller Degeneration attempted to explain all modern art, music and literature by pointing out the degenerate characteristics of the artists involved.
In the twentieth century, erradicating "degeneration" became a justification for various [eugenic] programs, mostly in Europe and the United States. Eugenicists adopted the concept, using it to justify the sterilization of the supposedly unfit. The Nazis took up these eugenic effots as well as the extermination of those who would otherwise corrupt future generations. They also used the concept in art, banning "degenerate" (entartete) art and music: see degenerate art.
