Ancient and medieval origins 's
The selection of the infant Spartans (1840) In ancient
Sparta, according to
Plutarch ( 50 to 120 CE), the council of elders (the
Gerousia) inspected every proper citizen's child and determined whether or not the child was fit to live. A child deemed unfit was allegedly thrown into a chasm. Plutarch's account is the sole historical source for the Spartan practice of
infanticide motivated by eugenics. While ancient Greeks practiced infanticide, no contemporary sources support Plutarch's claims of infanticide on eugenic grounds. In 2007, the tradition of dumping infants near Mount
Taygete was called into question due to a lack of physical evidence: anthropologist Theodoros Pitsios' research of the site found only bodies ranging in age from 18 to 35 years.
Plato's political philosophy included the belief that the state should cautiously monitor and control human reproduction through
selective breeding. According to
Tacitus (), a Roman of the
Imperial Period, the
Germanic tribes of his day killed any member of their community they deemed cowardly, un-warlike or "stained with abominable vices", usually by drowning them in swamps. Modern historians regard Tacitus' ethnographic writing as unreliable in such details.
Academic origins (1822–1911) was a British polymath who coined the term "eugenics"|203x203px The term
eugenics and its modern field of study were first formulated by
Francis Galton in 1883, directly drawing on the recent work delineating
natural selection by his half-cousin
Charles Darwin. He published his observations and conclusions chiefly in his influential book
Inquiries into Human Faculty and Its Development. Galton himself defined it as "the study of all agencies under human control which can improve or impair the racial quality of future generations". The first to systematically apply Darwinism theory to human relations, Galton believed that various desirable human qualities were also
hereditary ones, although Darwin strongly disagreed with this elaboration of his theory. Eugenics became an academic discipline at many colleges and universities and received funding from various sources. Organisations were formed to win public support for and to sway opinion towards responsible eugenic values in parenthood, including the British
Eugenics Education Society of 1907 and the
American Eugenics Society of 1921. Both sought support from leading clergymen and modified their message to meet religious ideals. In 1909, the Anglican clergymen
William Inge and
James Peile both wrote for the Eugenics Education Society. Inge was an invited speaker at the 1921
International Eugenics Conference, which was also endorsed by the Roman Catholic Archbishop of New York
Patrick Joseph Hayes. Eugenic policies also took root in France, Germany, and Great Britain. Later, in the 1920s and 1930s, the eugenic policy of
sterilising certain mental patients was implemented in other countries including Belgium, Brazil,
Canada,
Japan and
Sweden.
Frederick Osborn's 1937 journal article "Development of a Eugenic Philosophy" framed eugenics as a
social philosophy—a philosophy with implications for
social order. That definition is not universally accepted. Osborn advocated for higher rates of
sexual reproduction among people with desired traits ("positive eugenics") or reduced rates of sexual reproduction or
sterilisation of people with less-desired or undesired traits ("negative eugenics"). In addition to being practiced in a number of countries, eugenics was internationally organised through the
International Federation of Eugenics Organisations. Its scientific aspects were carried on through research bodies such as the
Kaiser Wilhelm Institute of Anthropology, Human Heredity, and Eugenics, the Cold Spring Harbor Carnegie Institution for
Experimental Evolution, and the
Eugenics Record Office. Politically, the movement advocated measures such as sterilisation laws. In its moral dimension, eugenics rejected the doctrine that all human beings are born equal and redefined moral worth purely in terms of genetic fitness. Its racist elements included pursuit of a pure "
Nordic race" or "
Aryan" genetic pool and the eventual elimination of "unfit" races. Many leading British politicians subscribed to the theories of eugenics.
Winston Churchill supported the British Eugenics Society and was an honorary vice president for the organisation. Churchill believed that eugenics could solve "race deterioration" and reduce crime and poverty. As a social movement, eugenics reached its greatest popularity in the early decades of the 20th century, when it was practiced around the world and promoted by governments, institutions, and influential individuals. Many countries enacted various eugenics policies, including:
genetic screenings,
birth control, promoting differential birth rates,
marriage restrictions, segregation (both
racial segregation and sequestering the mentally ill),
compulsory sterilisation,
forced abortions or
forced pregnancies, ultimately culminating in
genocide. By 2014, gene selection (rather than "people selection") was made possible through advances in
genome editing, leading to what is sometimes called
new eugenics, also known as "neo-eugenics", "consumer eugenics", or "liberal eugenics"; which focuses on individual freedom and allegedly pulls away from racism, sexism or a focus on intelligence.
Early opposition Early critics of the philosophy of eugenics included the American sociologist
Lester Frank Ward, the English writer
G. K. Chesterton, and Scottish tuberculosis pioneer and author
Halliday Sutherland. Ward's 1913 article "Eugenics, Euthenics, and Eudemics", Chesterton's 1917 book
Eugenics and Other Evils, and
Franz Boas' 1916 article "
Eugenics" (published in
The Scientific Monthly) were all harshly critical of the rapidly growing movement. Several biologists were also antagonistic to the eugenics movement, including
Lancelot Hogben. Other biologists who were themselves eugenicists, such as
J. B. S. Haldane and
R. A. Fisher, however, also expressed scepticism in the belief that sterilisation of "defectives" (i.e. a purely negative eugenics) would lead to the disappearance of undesirable genetic traits. Among institutions, the
Catholic Church opposes sterilisation for eugenic purposes. Attempts by the Eugenics Education Society to persuade the British government to legalise voluntary sterilisation were opposed by Catholics and by the
Labour Party. The
American Eugenics Society initially gained some Catholic supporters, but Catholic support declined following the 1930 papal encyclical
Casti connubii. The eugenicists' political successes in
Germany and
Scandinavia were not at all matched in such countries as
Poland and
Czechoslovakia, even though measures had been proposed there, largely because of the Catholic Church's moderating influence.
Eugenic feminism North American eugenics In Mexico Nazism and the decline of eugenics , a former centre for Nazi Germany's
Aktion T4 campaign The reputation of eugenics started to decline in the 1930s, a time when
Ernst Rüdin used eugenics as a justification for the
racial policies of Nazi Germany.
Adolf Hitler had praised and incorporated eugenic ideas in in 1925 and emulated eugenic legislation for the sterilisation of "defectives" that had been pioneered in the United States once he took power. Some common early 20th century eugenics methods involved identifying and classifying individuals and their families. This included
racial groups (such as the
Roma and
Jews in Nazi Germany), the poor, mentally ill, blind, deaf, developmentally disabled,
promiscuous women, and homosexuals as "degenerate" or "unfit". This led to segregation, institutionalisation, sterilisation, and
mass murder. The Nazi policy of identifying German citizens deemed unfit and then systematically murdering them with poison gas, referred to as the
Aktion T4 campaign, paved the way for the
Holocaust. By the end of
World War II, many eugenics laws were abandoned, having become associated with
Nazi Germany.
H. G. Wells, who had called for "the sterilisation of failures" in 1904, stated in his 1940 book
The Rights of Man: Or What Are We Fighting For? that among the human rights, which he believed should be available to all people, was "a prohibition on
mutilation, sterilisation,
torture, and any bodily punishment". After World War II, the practice of "imposing measures intended to prevent births within [a national, ethnical, racial or religious] group" fell within the definition of the new international crime of genocide, set out in the
Convention on the Prevention and Punishment of the Crime of Genocide. The
Charter of Fundamental Rights of the European Union also proclaims "the prohibition of eugenic practices, in particular those aiming at selection of persons".
In Singapore Lee Kuan Yew, the
founding father of
Singapore, actively promoted eugenics as late as 1983. In 1984, Singapore began providing financial incentives to highly educated women to encourage them to have more children. For this purpose was introduced the "Graduate Mother Scheme" that incentivised graduate women to get married as much as the rest of their populace. The incentives were extremely unpopular and regarded as eugenic, and were seen as discriminatory towards Singapore's non-Chinese ethnic population. In 1985, the incentives were partly abandoned as ineffective, while the government matchmaking agency, the
Social Development Network, remains active. == Modern eugenics ==
