Francis Galton
Sir Francis Galton (FRS; 16 February 1822 – 17 January 1911) was an English Victorian era polymath: a statistician, sociologist, psychologist, anthropologist, eugenicist, tropical explorer, geographer, inventor, meteorologist, proto-geneticist, and psychometrician. A Fellow of the Royal Society and half-cousin of Charles Darwin, he was knighted in 1909.
Life
Galton had a prolific intellect, and produced over 340 papers and books. He created the statistical concept of correlation and widely promoted regression toward the mean. He was the first to apply statistical methods to the study of human differences and inheritance of intelligence, and introduced the use of questionnaires and surveys for collecting data on human communities, which he needed for genealogical and biographical works and for his anthropometric studies. He was a pioneer of eugenics, coining the term itself in 1883, and also coined the phrase "nature versus nurture". His book Hereditary Genius (1869) was the first social scientific attempt to study genius and greatness.
As an investigator of the human mind, he founded psychometrics (the science of measuring mental faculties) and differential psychology, as well as the lexical hypothesis of personality. He devised a method for classifying fingerprints that proved useful in forensic science. He also conducted research on the power of prayer, concluding it had none due to its null effects on the longevity of those prayed for. His quest for the scientific principles of diverse phenomena extended even to the optimal method for making tea. As the initiator of scientific meteorology, he devised the first weather map, proposed a theory of anticyclones, and was the first to establish a complete record of short-term climatic phenomena on a European scale. He also invented the Galton Whistle for testing differential hearing ability.
Eugenics
The history of eugenics and racial hygiene (coined by Dr. med. Alfred Ploetz in 1895) starts in the 19th century. The term "eugenics" was coined by Galton in 1883. Eugenics – meaning ‘good breeding’ – describes ‘the science which deals with all influences which improve the inborn qualities of a race’. Galton linked the ideas about the »struggle for existence« influenced by Charles Darwin (1809–1882) with other racial doctrines. In order to prevent any degeneration of the populace and promote the higher development of mankind, undesirable sections of the population should be eradicated through sterilization or the selection of newborns (»negative eugenics«), while in contrast, desired ones were to be supported by measures relating to population policy and social welfare (»positive eugenics«).
Pre-Galton eugenics
Selective breeding was suggested at least as far back as Plato, who believed human reproduction should be controlled by government. He recorded these ideals in The Republic: "The best men must have intercourse with the best women as frequently as possible, and the opposite is true of the very inferior." Plato proposed that the process be concealed from the public via a form of lottery (Plato, The Republic, Book VI). Other ancient examples include Sparta's purported practice of infanticide. However, they would leave all babies outside for a length of time, and the survivors were considered stronger, while many "weaker" babies perished.
Galton's theory
Sir Francis Galton initially developed the ideas of eugenics using social statistics. During the 1860s and 1870s, Sir Francis Galton systematized these ideas and practices according to new knowledge about the evolution of man and animals provided by the theory of his cousin Charles Darwin. After reading Darwin's Origin of Species, Galton built upon Darwin's ideas whereby the mechanisms of natural selection were potentially thwarted by human civilization. He reasoned that, since many human societies sought to protect the underprivileged and weak, those societies were at odds with the natural selection responsible for extinction of the weakest. Only by changing these social policies, Galton thought, could society be saved from a "reversion towards mediocrity", a phrase that he first coined in statistics and which later changed to the now common "regression towards the mean".
Galton first sketched out his theory in the 1865 article "Hereditary Talent and Character", then elaborated it further in his 1869 book Hereditary Genius. He began by studying the way in which human intellectual, moral, and personality traits tended to run in families. Galton's basic argument was that "genius" and "talent" were hereditary traits in humans. He concluded that, since one could use artificial selection to exaggerate traits in other animals, one could expect similar results when applying such models to humans. As he wrote in the introduction to Hereditary Genius: I propose to show in this book that a man's natural abilities are derived by inheritance, under exactly the same limitations as are the form and physical features of the whole organic world. Consequently, as it is easy, notwithstanding those limitations, to obtain by careful selection a permanent breed of dogs or horses gifted with peculiar powers of running, or of doing anything else, so it would be quite practicable to produce a highly-gifted race of men by judicious marriages during several consecutive generations.
According to Galton, society already encouraged dysgenic conditions, claiming that the less intelligent were out-reproducing the more intelligent. Galton did not propose any selection methods; rather, he hoped that a solution would be found if social mores changed in a way that encouraged people to see the importance of breeding.
Galton first used the word eugenic in his 1883 Inquiries into Human Faculty and Its Development, a book in which he meant "to touch on various topics more or less connected with that of the cultivation of race, or, as we might call it, with 'eugenic' questions." He included a footnote to the word "eugenic" which read: That is, with questions bearing on what is termed in Greek, eugenes namely, good in stock, hereditarily endowed with noble qualities. This, and the allied words, eugeneia, etc., are equally applicable to men, brutes, and plants. We greatly want a brief word to express the science of improving stock, which is by no means confined to questions of judicious mating, but which, especially in the case of man, takes cognisance of all influences that tend in however remote a degree to give to the more suitable races or strains of blood a better chance of prevailing speedily over the less suitable than they otherwise would have had. The word eugenics would sufficiently express the idea; it is at least a neater word and a more generalised one than viriculture which I once ventured to use.
In 1904, he clarified his definition of eugenics as "the science which deals with all influences that improve the inborn qualities of a race; also with those that develop them to the utmost advantage."
Galton's formulation of eugenics was based on a strong statistical approach, influenced heavily by Adolphe Quetelet's "social physics". Unlike Quetelet, however, Galton did not exalt the "average man" but decried him as mediocre. Galton and his statistical heir Karl Pearson developed what was called the biometrical approach to eugenics, which developed new and complex statistical models (later exported to wholly different fields) to describe the heredity of traits. However, with the rediscovery of Gregor Mendel's hereditary laws, two separate camps of eugenics advocates emerged. One was made up of statisticians, the other of biologists. Statisticians thought the biologists had exceptionally crude mathematical models, while biologists thought the statisticians knew little about biology.
Eugenics eventually referred to human selective reproduction with an intent to create children with desirable traits, generally through the approach of influencing differential birth rates. These policies were mostly divided into two categories: positive eugenics, the increased reproduction of those seen to have advantageous hereditary traits; and negative eugenics, the discouragement of reproduction by those with hereditary traits perceived as poor. Negative eugenic policies in the past have ranged from attempts at segregation to sterilization and even genocide. Positive eugenic policies have typically taken the form of awards or bonuses for "fit" parents who have another child. Relatively innocuous practices like marriage counseling had early links with eugenic ideology.
Eugenics differed from what would later be known as Social Darwinism. While both claimed intelligence was hereditary, eugenics asserted that new policies were needed to actively change the status quo towards a more "eugenic" state, while the Social Darwinists argued society itself would naturally "check" the problem of "dysgenics" if no welfare policies were in place (for example, the poor might reproduce more but would have higher mortality rates).
