21 Social Darwinism Application of principles of evolution to societies Predates “Origin of Species” (philosophical works by Herbert Spencer and others) Concepts of competition and genetic superiority /inferiority Justified nationalism and colonialism Most extreme example: Nazi philosophy

22 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

23 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
