Euthenics /juːˈθɛnɪks/ is the study of the improvement of human functioning and well-being by improvement of living conditions. Affecting the 'improvement' through altering external factors such as education and the controllable environment, including the prevention and removal of contagious disease and parasites, environmentalism, education regarding employment, home economics, sanitation, and housing.The betterment of living conditions, through conscious endeavor, for the purpose of securing efficient human beings, is what the author means by Euthenics.Is there, then, nothing to do? Are we to accept that modem scientific fatalism known as laissez faire, which enjoins the folding of the arms? Are we to preach a gospel of inaction? I for one certainly am not content to do so, and I believe that nothing I have thus far said is inconsistent with the most vigorous action, and that in the direction of the betterment of the human race. The end and aim of the eugenists cannot be reproached. The race is far from perfect. Its condition is deplorable. Its improvement is entirely feasible, and in the highest degree desirable. Nor do I refer merely to economic conditions, to the poverty and misery of the disinherited classes. The intellectual state of the world is deplorable, and its improvement is clearly within the reach of society itself. It is therefore a question of method rather than of principle that concerns us.Darwin has taught us that the chief barrier to the advance of any species of plants or animals is its competition with other plants and animals that contest the same ground. And therefore the fiercest opponents of any species are the members of the same species which demand the same elements of subsistence. Hence the chief form of relief in the organic world consists in the thinning-out of competitors. Any species of animals or plants left free to propagate at its normal rate would overrun the earth in a short time and leave no room for any other species. Any species that is sufficiently vigorous to resist its organic environment will crowd out all others and monopolize the earth. If nature permitted this there could be no variety, but only one monotonous aspect devoid of interest or beauty. Whatever we may think of the harsh method by which this is prevented, we cannot regret that it is prevented, and that we have a world of variety, interest, and aesthetic attractiveness.Thus the two schools of euthenics and eugenics stand opposed, each viewing the other unkindly. Against eugenics it is urged that it is a fatalistic doctrine and deprives life of the stimulus toward effort. Against euthenics the other side urges that it demands an endless amount of money to patch up conditions in the vain effort to get greater efficiency. Which of the two doctrines is true?'Not through chance, but through increase of scientific knowledge; not through compulsion, but through democratic idealism consciously working through common interests, will be brought about the creation of right conditions, the control of the environment.' (Ellen H. Swallow Richards)'Right living conditions comprise pure food and a safe water supply, a clean and disease free atmosphere in which to live and work, proper shelter and adjustment of work, rest, and amusements.' (Ellen H. Swallow Richards)'Probably not more than twenty-five percent in any community are capable of doing a full days work such as they would be capable of doing if they were in perfect health' (Ellen H. Swallow Richards)'Men ignore nature's laws in their personal lives. They crave a larger measure of goodness and happiness, and yet in their choice of dwelling places, in their building of houses to live in, in their selection of food and drink, in their clothing of their bodies, in their choice of occupations and amusements, in their methods and habits of work, they disregard natural laws and impose upon themselves conditions that make their ideals of goodness and happiness impossible of attainment.' (George E. Dawson, The control of life through Environment)'It is within the power of every living man to rid himself of every parasitic disease.' (Louis Pasteur) Euthenics /juːˈθɛnɪks/ is the study of the improvement of human functioning and well-being by improvement of living conditions. Affecting the 'improvement' through altering external factors such as education and the controllable environment, including the prevention and removal of contagious disease and parasites, environmentalism, education regarding employment, home economics, sanitation, and housing. Rose Field notes of the definition in a May 23, 1926 New York Times article, 'the simplest being efficient living'. A right to environment. The Flynn effect has been often cited as an example of euthenics. Another example is the steady increase in body size in industrialized countries since the beginning of the 20th century. Euthenics is not normally interpreted to have anything to do with changing the composition of the human gene pool by definition, although everything that affects society has some effect on who reproduces and who does not. The term was derived in the late 19th century from the Greek verb eutheneo, εὐθηνέω (eu, well; the, root of τίθημι tithemi, to cause). (To be in a flourishing state, to abound in, to prosper.—Demosthenes. To be strong or vigorous.—Herodotus. To be vigorous in body.—Aristotle.) Also from the Greek Euthenia, Εὐθηνία. Good state of the body: prosperity, good fortune, abundance.—Herodotus. The opposite of Euthenia is Penia, Πενία ('deficiency' or 'poverty') the personification of poverty and need. Ellen Swallow Richards (Born in 1842–died in 1911; Vassar Class of '70) was one of the first writers to use the term, in The Cost of Shelter (1905), with the meaning 'the science of better living'. It is unclear if (and probably unlikely that) any of the study programs of euthenics ever completely embraced Richards' multidisciplinary concept, though several nuances remain today, especially that of interdisciplinarity.
