Eugenics
Eugenics (; from Greek εὐγενής eugenes 'well-born' from εὖ eu, 'good, well' and γένος genos, 'race, stock, kin') is a set of beliefs and practices that aims at improving the genetic quality of a human population. The exact definition of eugenics has been a matter of debate since the term was coined by Francis Galton in 1883. The concept predates this coinage, with Plato suggesting applying the principles of selective breeding to humans around 400 BCE.
Frederick Osborn's 1937 journal article "Development of a Eugenic Philosophy" framed it as a social philosophy—that is, a philosophy with implications for social order. That definition is not universally accepted.
