The popular commentator Glenn Beck has referred to Charles Darwin as "the father of modern-day racism." Certainly, Beck's sentiments are nothing new; links between Darwin and racism, as well as to eugenics and other destructive ideologies, are mentioned constantly by opponents to the modern theory of evolution. But are these links valid? In the video below, Denis Alexander shares his thoughts on the relationship between evolution and ideologies.
Alexander notes that while the biological theory of evolution is not itself an ideology, it has been used for ideological purposes since 1859 to defend everything from eugenics to capitalism to racism to atheism. The reason, he asserts, is not because of any true support, but rather because people often try to use the popular scientific theories of the day to support all sorts of ideologies.
He also notes that the phrase "survival of the fittest", often tied to Darwin and stated as a core part of evolution, was in fact coined by science popularizer Herbert Spencer, and that the phrase is in fact a poor description of the complicated processes involved in evolution. Unfortunately, the phrase was picked up during the World War I-era as a way to support the "might makes right" mentality, and the misunderstanding was used to justify all sorts of failed ideologies.
Similarly, Alexander notes that the fact that evolution admits there are variations between people in regards to genetics has been used to justify racist ideology. However, once again, this is a case of ideology using something for its own agenda; the biological process of evolution itself does not in any way justify such racist thinking, and in fact diversity is beneficial to populations.
