Eugenics (; from Greek εὐγενής ''eugenes'' "well-born" from εὖ ''eu'', "good, well" and γένος ''genos'', "race, stock, kin")〔("eugenics" ). ''Online Etymology Dictionary.''〕〔("γένος" ). ''A Greek–English Lexicon''.〕 is a set of beliefs and practices which aims at improving the genetic quality of the human population. It is a social philosophy advocating the improvement of human genetic traits through the promotion of higher rates of sexual reproduction for people with desired traits (positive eugenics), or reduced rates of sexual reproduction and sterilization of people with less-desired or undesired traits (negative eugenics), or both.〔 Alternatively, gene selection rather than "people selection" has recently been made possible through advancements in gene editing (e.g. CRISPR). The exact definition of ''eugenics'' has been a matter of debate since the term was coined. The definition of it as a "social philosophy"—that is, a philosophy with implications for social order—is not universally accepted, and was taken from Frederick Osborn's 1937 journal article "Development of a Eugenic Philosophy". While eugenic principles have been practiced as far back in world history as Ancient Greece, the modern history of eugenics began in the early 20th century when a popular eugenics movement emerged in Britain and spread to many countries, including the United States and most European countries. In this period, eugenic ideas were espoused across the political spectrum. Consequently, many countries adopted eugenic policies meant to improve the genetic stock of their countries. Such programs often included both "positive" measures, such as encouraging individuals deemed particularly "fit" to reproduce, and "negative" measures such as marriage prohibitions and forced sterilization of people deemed unfit for reproduction. People deemed unfit to reproduce often included people with mental or physical disabilities, people who scored in the low ranges of different IQ tests, criminals and deviants, and members of disfavored minority groups. The eugenics movement became negatively associated with Nazi Germany and the Holocaust—the murder by the German state of approximately 12 million people—when many of the defendants at the Nuremberg trials attempted to justify their human rights abuses by claiming there was little difference between the Nazi eugenics programs and the US eugenics programs. In the decades following World War II, with the institution of human rights, many countries gradually abandoned eugenics policies, although some Western countries, among them Sweden and the US, continued to carry out forced sterilizations for several decades. Since the 1980s and 1990s when new assisted reproductive technology procedures became available, such as gestational surrogacy (available since 1985), preimplantation genetic diagnosis (available since 1989) and cytoplasmic transfer (first performed in 1996), fear about a possible future revival of eugenics and a widening of the gap between the rich and the poor has emerged, despite the immense medical benefits these technologies offer. A major critique of eugenics policies is that regardless of whether "negative" or "positive" policies are used, they are vulnerable to abuse because the criteria of selection are determined by whichever group is in political power. Furthermore, negative eugenics in particular is considered by many to be a violation of basic human rights, which include the right to reproduction. ==History== (詳細はPlato suggested selective mating to produce a guardian class. The idea of eugenics to decrease the birth of inferior human beings has existed at least since William Goodell (1829-1894) advocated the castration and spaying of the insane. However, the term "eugenics" to describe the modern concept of improving the quality of human beings born into the world was originally developed by Francis Galton. Galton had read his half-cousin Charles Darwin's theory of evolution, which sought to explain the development of plant and animal species, and desired to apply it to humans. Galton believed that desirable traits were hereditary based on biographical studies.〔(【引用サイトリンク】url=http://www.credoreference.com/entry/abcmigrate/eugenics )〕 In 1883, one year after Darwin's death, Galton gave his research a name: ''eugenics''. Throughout its recent history, eugenics has remained a controversial concept. Eugenics became an academic discipline at many colleges and universities, and received funding from many sources. Organisations formed to win public support, and modify opinion towards responsible eugenic values in parenthood, included 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. Three International Eugenics Conferences presented a global venue for eugenists with meetings in 1912 in London, and in 1921 and 1932 in New York. Eugenic policies were first implemented in the early 1900s in the United States. It has roots in France, Germany, Great Britain, and the United States. Later, in the 1920s and 30s, the eugenic policy of sterilizing certain mental patients was implemented in other countries, including Belgium, Brazil, Canada, Japan, and Sweden. The scientific 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. Nevertheless, in Sweden the eugenics program continued until 1975.〔 In addition to being practised in a number of countries, eugenics was internationally organized through the International Federation of Eugenics Organizations. Its scientific aspects were carried on through research bodies such as the Kaiser Wilhelm Institute of Anthropology, Human Heredity, and Eugenics, the Cold Spring Harbour Carnegie Institution for Experimental Evolution, and the Eugenics Record Office. Its political aspects involved advocating laws allowing the pursuit of eugenic objectives, such as sterilization laws. Its moral aspects included rejection of the doctrine that all human beings are born equal, and redefining morality 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 "less fit" races. As a social movement, eugenics reached its greatest popularity in the early decades of the 20th century. At this point in time, eugenics was practiced around the world and was promoted by governments and influential individuals and institutions. Many countries enacted various eugenics policies and programmes, including: genetic screening, birth control, promoting differential birth rates, marriage restrictions, segregation (both racial segregation and segregation of the mentally ill from the rest of the population), compulsory sterilization, forced abortions or forced pregnancies, and genocide. Most of these policies were later regarded as coercive or restrictive, and now few jurisdictions implement policies that are explicitly labelled as eugenic or unequivocally eugenic in substance. The methods of implementing eugenics varied by country; however, some early 20th century methods involved identifying and classifying individuals and their families, including the poor, mentally ill, blind, deaf, developmentally disabled, promiscuous women, homosexuals, and racial groups (such as the Roma and Jews in Nazi Germany) as "degenerate" or "unfit", the segregation or institutionalization of such individuals and groups, their sterilization, euthanasia, and their mass murder. The practice of euthanasia was carried out on hospital patients in the Aktion T4 centers such as Hartheim Castle. By the end of World War II, many of the discriminatory eugenics laws were largely abandoned, having become associated with Nazi Germany.〔Lynn 2001. p. 18 "By the middle decades of the twentieth century, eugenics had become widely accepted throughout the whole of the economically developed world, with the exception of the Soviet Union."〕 After World War II, the practice of "imposing measures intended to prevent births within (population ) 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.〔Article 2 of the Convention defines genocide as any of the following acts committed with intent to destroy, in whole or in part, a national, ethnic, racial or religious group, as such as: * Killing members of the group; * Causing serious bodily or mental harm to members of the group; * Deliberately inflicting on the group conditions of life calculated to bring about its physical destruction in whole or in part; * Imposing measures intended to prevent births within the group; * Forcibly transferring children of the group to another group. See 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 spite of the decline in discriminatory eugenics laws, government practices of compulsive sterilization continued into the 21st century. During the ten years President Alberto Fujimori led Peru from 1990 to 2000, allegedly 2,000 persons were involuntarily sterilized.〔CNN, Peru will not prosecute former President over sterilization campaign, Retrieved August 30, 2014. http://www.cnn.com/2014/01/25/world/americas/peru-sterilization/〕 China maintains its forcible one-child policy as well as a suite of other eugenics based legislation in order to reduce population size and manage fertility rates of different populations.〔Dikötter, F.

UNESCO Courier, 1.〕 In 2007 the United Nations reported forcible sterilisations and hysterectomies in Uzbekistan.〔BBC News, Uzbekistan's policy of secretly sterilizing women, retrieved on August 30, 2014. http://www.bbc.com/news/magazine-17612550〕 During the years 2005–06 to 2012–13, nearly one-third of the 144 California prison inmates who were sterilized did not give lawful consent to the operation. Developments in genetic, genomic, and reproductive technologies at the end of the 20th century are raising numerous questions regarding the ethical status of eugenics, effectively creating a resurgence of interest in the subject. Some, such as UC Berkeley sociologist Troy Duster, claim that modern genetics is a back door to eugenics. This view is shared by White House Assistant Director for Forensic Sciences, Tania Simoncelli, who stated in a 2003 publication by the Population and Development Program at Hampshire College that advances in pre-implantation genetic diagnosis (PGD) are moving society to a "new era of eugenics", and that, unlike the Nazi eugenics, modern eugenics is consumer driven and market based, "where children are increasingly regarded as made-to-order consumer products".〔Tania Simoncelli, "Pre-Implantation Genetic Diagnosis and Selection: from disease prevention to customised conception", ''Different Takes'', No. 24 (Spring 2003). http://genetics.live.radicaldesigns.org/downloads/200303_difftakes_simoncelli.pdf Retrieved on September 18, 2013.〕 In a 2006 newspaper article, Richard Dawkins said that discussion regarding eugenics was inhibited by the shadow of Nazi misuse, to the extent that some scientists would not admit that breeding humans for certain abilities is at all possible. He believes that it is not physically different from breeding domestic animals for traits such as speed or herding skill. Dawkins felt that enough time had elapsed to at least ask just what the ethical differences were between breeding for ability versus training athletes or forcing children to take music lessons, though he could think of persuasive reasons to draw the distinction.〔From the Afterward, by Richard Dawkins, ''The Herald'', (2006). http://www.heraldscotland.com/from-the-afterword-1.836155 Retrieved on Oct 17, 2013〕 Some, such as Nathaniel C. Comfort from Johns Hopkins University, claim that the change from state-led reproductive-genetic decision-making to individual choice has moderated the worst abuses of eugenics by transferring the decision-making from the state to the patient and their family. Comfort suggests that "()he eugenic impulse drives us to eliminate disease, live longer and healthier, with greater intelligence, and a better adjustment to the conditions of society; and the health benefits, the intellectual thrill and the profits of genetic bio-medicine are too great for us to do otherwise." Others, such as bioethicist Stephen Wilkinson of Keele University and Honorary Research Fellow Eve Garrard at the University of Manchester, claim that some aspects of modern genetics can be classified as eugenics, but that this classification does not inherently make modern genetics immoral. In a co-authored publication by Keele University, they stated that "()ugenics doesn't seem always to be immoral, and so the fact that PGD, and other forms of selective reproduction, might sometimes technically be eugenic, isn't sufficient to show that they're wrong."〔Eugenics and the Ethics of Selective Reproduction, Stephen and Eve Garrard, published by Keele University 2013. http://www.keele.ac.uk/media/keeleuniversity/ri/risocsci/eugenics2013/Eugenics%20and%20the%20ethics%20of%20selective%20reproduction%20Low%20Res.pdf Retrieved on September 18, 2013〕 In October 2015, the United Nations' International Bioethics Committee wrote that the ethical problems of human genetic engineering should not be confused with the ethical problems of the 20th century eugenics movements; however, it is still problematic because it challenges the idea of human equality and opens up new forms of discrimination and stigmatization for those who do not want or cannot afford the enhancements. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「eugenics」の詳細全文を読む スポンサード リンク
