Social Darwinism
• Application of principles of evolution to societies
• Predates “Origin of Species” (philosophical works byHerbert Spencer and others)
• Concepts of competition and genetic superiority /inferiority
• Justified nationalism and colonialism
• Most extreme example: Nazi philosophy
Eugenics
• Long history in many cultures (infanticide as a form of selection)
• Plato: state regulated marriage and reproduction
• Francis Galton: modern concept and term
• Encourage those with desirable traits to reproduce; discourage those with undesirable traits from reproducing
• In early days, weakly correlated with political views
Two U.S. Examples:
1) Compulsory Sterilization
• 1907 Indianna• By 1950, around half the states• Practice varied immensely• Buck v Bell
2) Immigration restriction
• Initially US had almost unrestricted immigration• 1870s onward: restrictions on Asian immigrants• Early 1900s: restrictions on indigents, unhealthy• 1920s: restrictions based on nationality
