Eugenics
In The Origin of Species, Charles Darwin wove the eugenic philosophy of Plato into the theory of natural selection. By arguing that “extinction and natural selection go hand in hand,” Darwin legitimized the eugenics movements of the 20th century.
Eugenics originated in ancient cultures. Rome, Athens, and Sparta practiced eugenics to improve the strength and survival of their societies. Encouraged by his brother, Erasmus, Darwin read An Essay on the Principle of Population by Thomas Robert Malthus, an English political economist, in 1838.
