Social Darwinism is a modern name given to various theories of society that emerged in the United Kingdom, the United States, and Western Europe in the 1870s, and which sought to apply biological concepts of natural selection and survival of the fittest to sociology and politics. Social Darwinists generally argue that the strong should see their wealth and power increase while the weak should see their wealth and power decrease. Different social Darwinists have different views about which groups of people are the strong and the weak, and they also hold different opinions about the precise mechanism that should be used to promote strength and punish weakness. Many such views stress competition between individuals in laissez-faire capitalism, while others motivated ideas of eugenics, racism, imperialism, and struggle between national or racial groups.
The term social Darwinism gained widespread currency when used after 1944 by opponents of these earlier concepts. Today, because of the negative connotations of the theory of social Darwinism, especially after the atrocities of the Second World War, few people would describe themselves as social Darwinists and the term is generally seen as pejorative.
Creationists have often maintained that social Darwinism—leading to policies designed to make the weak perish—is a logical consequence of "Darwinism" (the theory of natural selection in biology). Biologists and historians have stated that this is a naturalistic fallacy, since the theory of natural selection is merely intended as a description of a biological phenomenon and should not be taken to imply that this phenomenon is good or that it ought to be used as a moral guide in human society. Social Darwinism owed more to Herbert Spencer's ideas, together with genetics and a Protestant Nonconformist tradition with roots in Hobbes and Malthus, than to Charles Darwin's research. While most scholars recognize some historical links between the popularisation of Darwin's theory and forms of social Darwinism, they also maintain that social Darwinism is not a necessary consequence of the principles of biological evolution.
Scholars debate the extent to which the various social Darwinist ideologies reflect Charles Darwin's own views on human social and economic issues. His writings have passages that can be interpreted as opposing aggressive individualism, while other passages appear to promote it. Some scholars argue that Darwin's view gradually changed and came to incorporate views from the leading social interpreters of his theory such as Spencer, but Spencer's Lamarckian evolutionary ideas about society were published before Darwin first published his theory, and both promoted their own conceptions of moral values. Spencer supported laissez-faire capitalism on the basis of his Lamarckian belief that struggle for survival spurred self-improvement which could be inherited.

Origin of the term
The term first appeared in Europe in 1877, and around this time it was used by sociologists opposed to the concept. The term was popularized in the United States in 1944 by the American historian Richard Hofstadter who used it in the ideological war effort against fascism to denote a reactionary creed which promoted competitive strife, racism and chauvinism. Hofstadter later also recognized (what he saw as) the influence of Darwinist and other evolutionary ideas upon those with collectivist views, enough to devise a term for the phenomenon, "Darwinist collectivism." Before Hofstadter's work the use of the term "social Darwinism" in English academic journals was quite rare. In fact,
...there is considerable evidence that the entire concept of "social Darwinism" as we know it today was virtually invented by Richard Hofstadter. Eric Foner, in an introduction to a then-new edition of Hofstadter's book published in the early 1990s, declines to go quite that far. "Hofstadter did not invent the term Social Darwinism," Foner writes, "which originated in Europe in the 1860s and crossed the Atlantic in the early twentieth century. But before he wrote, it was used only on rare occasions; he made it a standard shorthand for a complex of late-nineteenth-century ideas, a familiar part of the lexicon of social thought."—Jeff Riggenbach
The term "social Darwinism" has rarely been used by advocates of the supposed ideologies or ideas; instead it has almost always been used (pejoratively) by its opponents, with one modern exception. The term "social Darwinism" is self-ascribed in the case of the survival of the fittest," a term coined by sociologist Herbert Spencer.
While the term has been applied to the claim that Darwin's theory of evolution by natural selection can be used to understand the social endurance of a nation or country, social Darwinism commonly refers to ideas that predate Darwin's publication of On the Origin of Species. Others whose ideas are given the label include the 18th century clergyman Thomas Malthus, and Darwin's cousin Francis Galton who founded eugenics towards the end of the 19th century.
Theories and origins
The term Darwinism had been coined by Thomas Henry Huxley in his April 1860 review of "On the Origin of Species", and by the 1870s it was used to describe a range of concepts of evolutionism or development, without any specific commitment to Charles Darwin's own theory.
The first use of the phrase "social Darwinism" was in Joseph Fisher's 1877 article on The History of Landholding in Ireland which was published in the Transactions of the Royal Historical Society. Fisher was commenting on how a system for borrowing livestock which had been called "tenure" had led to the false impression that the early Irish had already evolved or developed land tenure;
Despite the fact that social Darwinism bears Charles Darwin's name, it is also linked today with others, notably Herbert Spencer, Thomas Malthus, and Francis Galton, the founder of eugenics. In fact, Spencer was not described as a social Darwinist until the 1930s, long after his death.
Darwin himself gave serious consideration to Galton's work, but considered the ideas of "hereditary improvement" impractical. Aware of weaknesses in his own family, Darwin was sure that families would naturally refuse such selection and wreck the scheme. He thought that even if compulsory registration was the only way to improve the human race, this illiberal idea would be unacceptable, and it would be better to publicize the "principle of inheritance" and let people decide for themselves.
In The Descent of Man, and Selection in Relation to Sex of 1882 Darwin described how medical advances meant that the weaker were able to survive and have families, and as he commented on the effects of this, he cautioned that hard reason should not override sympathy and considered how other factors might reduce the effect:
Thus the weak members of civilized societies propagate their kind. No one who has attended to the breeding of domestic animals will doubt that this must be highly injurious to the race of man. It is surprising how soon a want of care, or care wrongly directed, leads to the degeneration of a domestic race; but excepting in the case of man himself, hardly any one is so ignorant as to allow his worst animals to breed.
The aid which we feel impelled to give to the helpless is mainly an incidental result of the instinct of sympathy, which was originally acquired as part of the social instincts, but subsequently rendered, in the manner previously indicated, more tender and more widely diffused. Nor could we check our sympathy, even at the urging of hard reason, without deterioration in the noblest part of our nature. The surgeon may harden himself whilst performing an operation, for he knows that he is acting for the good of his patient; but if we were intentionally to neglect the weak and helpless, it could only be for a contingent benefit, with an overwhelming present evil. ... We must therefore bear the undoubtedly bad effects of the weak surviving and propagating their kind; but there appears to be at least one check in steady action, namely that the weaker and inferior members of society do not marry so freely as the sound; and this check might be indefinitely increased by the weak in body or mind refraining from marriage, though this is more to be hoped for than expected.
Herbert Spencer's ideas, like those of evolutionary progressivism, stemmed from his reading of Thomas Malthus, and his later theories were influenced by those of Darwin. However, Spencer's major work, Progress: Its Law and Cause (1857) was released three years before the publication of Darwin's On the Origin of Species, and First Principles was printed in 1860.
In The Social Organism (1860), Spencer compares society to a living organism and argues that, just as biological organisms evolve through natural selection, society evolves and increases in complexity through analogous processes.
Jeff Riggenbach argues that Spencer's view was that culture and education made a sort of Lamarckism possible and notes that Herbert Spencer was a proponent of private charity.
Spencer's work also served to renew interest in the work of Malthus. While Malthus's work does not itself qualify as social Darwinism, his 1798 work An Essay on the Principle of Population, was incredibly popular and widely read by social Darwinists. In that book, for example, the author argued that as an increasing population would normally outgrow its food supply, this would result in the starvation of the weakest and a Malthusian catastrophe.
According to Michael Ruse, Darwin read Malthus' famous Essay on a Principle of Population in 1838, four years after Malthus' death. Malthus himself anticipated the social Darwinists in suggesting that charity could exacerbate social problems.
Another of these social interpretations of Darwin's biological views, later known as eugenics, was put forth by Darwin's cousin, Francis Galton, in 1865 and 1869. Galton argued that just as physical traits were clearly inherited among generations of people, the same could be said for mental qualities (genius and talent). Galton argued that social morals needed to change so that heredity was a conscious decision in order to avoid both the over-breeding by less fit members of society and the under-breeding of the more fit ones.
In Galton's view, social institutions such as welfare and insane asylums were allowing inferior humans to survive and reproduce at levels faster than the more "superior" humans in respectable society, and if corrections were not soon taken, society would be awash with "inferiors." Darwin read his cousin's work with interest, and devoted sections of Descent of Man to discussion of Galton's theories. Neither Galton nor Darwin, though, advocated any eugenic policies such as those that would be undertaken in the early 20th century, for government coercion of any form was very much against their political opinions.
 Thus, he wrote:
Wherever progress is to ensue, deviating natures are of greatest importance. Every progress of the whole must be preceded by a partial weakening. The strongest natures retain the type, the weaker ones help to advance it. Something similar also happens in the individual. There is rarely a degeneration, a truncation, or even a vice or any physical or moral loss without an advantage somewhere else. In a warlike and restless clan, for example, the sicklier man may have occasion to be alone, and may therefore become quieter and wiser; the one-eyed man will have one eye the stronger; the blind man will see deeper inwardly, and certainly hear better. To this extent, the famous theory of the survival of the fittest does not seem to me to be the only viewpoint from which to explain the progress of strengthening of a man or of a race.
The publication of Ernst Haeckel's best-selling Welträtsel ('Riddle of the Universe') in 1899 brought social Darwinism and earlier ideas of racial hygiene to a wider audience. His recapitulation theory was not Darwinism, but rather attempted to combine the ideas of Goethe, Lamarck and Darwin. It was adopted by emerging social sciences to support the concept that non-European societies were "primitive" in an early stage of development towards the European ideal, but since then it has been heavily refuted on many fronts Haeckel's works led to the formation of the Monist League in 1904 with many prominent citizens among its members, including the Nobel Prize winner Wilhelm Ostwald. By 1909, it had a membership of some six thousand people.
The simpler aspects of social Darwinism followed the earlier Malthusian ideas that humans, especially males, require competition in their lives in order to survive in the future. Further, the poor should have to provide for themselves and not be given any aid. However, amidst this climate, most social Darwinists of the early twentieth century actually supported better working conditions and salaries. Such measures would grant the poor a better chance to provide for themselves yet still distinguish those who are capable of succeeding from those who are poor out of laziness, weakness, or inferiority.
"Social Darwinism" was first described by Oscar Schmidt of the University of Strasbourg, reporting at a scientific and medical conference held in Munich in 1877. He noted how socialists, although opponents of Darwin's theory, nonetheless used it to add force to their political arguments. Schmidt's essay first appeared in English in Popular Science in March 1879. There followed an anarchist tract published in Paris in 1880 entitled "Le darwinisme social" by Émile Gautier. However, the use of the term was very rare — at least in the English-speaking world (Hodgson, 2004)— until the American historian Richard Hofstadter published his influential Social Darwinism in American Thought (1944) during World War II.
Hypotheses of social evolution and Hegel, often argued that societies progressed through stages of increasing development. Earlier thinkers also emphasized conflict as an inherent feature of social life. Thomas Hobbes's 17th century portrayal of the state of nature seems analogous to the competition for natural resources described by Darwin. Social Darwinism is distinct from other theories of social change because of the way it draws Darwin's distinctive ideas from the field of biology into social studies.
Darwin, unlike Hobbes, believed that this struggle for natural resources allowed individuals with certain physical and mental traits to succeed more frequently than others, and that these traits accumulated in the population over time, which under certain conditions could lead to the descendants being so different that they would be defined as a new species.
However, Darwin felt that "social instincts" such as "sympathy" and "moral sentiments" also evolved through natural selection, and that these resulted in the strengthening of societies in which they occurred, so much so that he wrote about it in Descent of Man:
The following proposition seems to me in a high degree probable—namely, that any animal whatever, endowed with well-marked social instincts, the parental and filial affections being here included, would inevitably acquire a moral sense or conscience, as soon as its intellectual powers had become as well, or nearly as well developed, as in man. For, firstly, the social instincts lead an animal to take pleasure in the society of its fellows, to feel a certain amount of sympathy with them, and to perform various services for them.
Spencer proved to be a popular figure in the 1880s primarily because his application of evolution to areas of human endeavor promoted an optimistic view of the future as inevitably becoming better. In the United States, writers and thinkers of the gilded age such as Edward L. Youmans, William Graham Sumner, John Fiske, John W. Burgess, and others developed theories of social evolution as a result of their exposure to the works of Darwin and Spencer.
In 1883, Sumner published a highly influential pamphlet entitled "What Social Classes Owe to Each Other", in which he insisted that the social classes owe each other nothing, synthesizing Darwin's findings with free enterprise Capitalism for his justification. According to Sumner, those who feel an obligation to provide assistance to those unequipped or under-equipped to compete for resources, will lead to a country in which the weak and inferior are encouraged to breed more like them, eventually dragging the country down. Sumner also believed that the best equipped to win the struggle for existence was the American businessman, and concluded that taxes and regulations serve as dangers to his survival. This pamphlet makes no mention of Darwinism, and only refers to Darwin in a statement on the meaning of liberty, that "There never has been any man, from the primitive barbarian up to a Humboldt or a Darwin, who could do as he had a mind to."
Sumner never fully embraced Darwinian ideas, and some contemporary historians do not believe that Sumner ever actually believed in social Darwinism. The great majority of American businessmen rejected the anti-philanthropic implications of the theory. Instead they gave millions to build schools, colleges, hospitals, art institutes, parks and many other institutions. Andrew Carnegie, who admired Spencer, was the leading philanthropist in the world (1890–1920), and a major leader against imperialism and warfare.
Social Darwinism has influenced political, public health and social movements in Japan since the late 19th and early 20th century. Social Darwinism was originally brought to Japan through the works of Francis Galton and Ernst Haeckel as well as United States, British and French Lamarkian eugenic written studies of the late 19th and early 20th centuries. Eugenism as a science was hotly debated at the beginning of the 20th century, in Jinsei-Der Mensch, the first eugenics journal in the empire. As Japan sought to close ranks with the west, this practice was adopted wholesale along with colonialism and its justifications.
Social Darwinism was formally introduced to China through the translation by Yan Fu of Huxley's Evolution and Ethics, in the course of an extensive series of translations of influential Western thought. Yan's translation strongly impacted Chinese scholars because he added national elements not found in the original. He understood Spencer's sociology as "not merely analytical and descriptive, but prescriptive as well," and saw Spencer building on Darwin, whom Yan summarized thus:
- Peoples and living things struggle for survival. At first, species struggle with species; they as [people] gradually progress, there is a struggle between one social group and another. The weak invariably become the prey of the strong, the stupid invariably become subservient to the clever."
By the 1920s, social Darwinism found expression in the promotion of eugenics by the Chinese sociologist Pan Guangdan. When Chiang Kai-shek started the New Life movement in 1934, he
- . . . harked back to theories of Social Darwinism, writing that "only those who readapt themselves to new conditions, day by day, can live properly. When the life of a people is going through this process of readaptation, it has to remedy its own defects, and get rid of those elements which become useless. Then we call it new life."
Nazi Germany's justification for its aggression was regularly promoted in Nazi propaganda films depicting scenes such as beetles fighting in a lab setting to demonstrate the principles of "survival of the fittest" as depicted in Alles Leben ist Kampf (English translation: All Life is Struggle). Hitler often refused to intervene in the promotion of officers and staff members, preferring instead to have them fight amongst themselves to force the "stronger" person to prevail—"strength" referring to those social forces void of virtue or principle. Key proponents were Alfred Rosenberg, who was hanged later at Nuremberg.
The argument that Nazi ideology was strongly influenced by social Darwinist ideas is often found in historical and social science literature. For example, the Jewish philosopher and historian Hannah Arendt analysed the historical development from a politically indifferent scientific Darwinism via social Darwinist ethics to racist ideology.
By 1985, the argument has been taken up by opponents of evolutionary theory. Such claims have been presented by creationists such as Jonathan Sarfati. Intelligent design creationism supporters have promoted this position as well. For example, it is a theme in the work of Richard Weikart, who is a historian at California State University, Stanislaus, and a senior fellow for the Center for Science and Culture of the Discovery Institute. It is also a main argument in the 2008 intelligent-design/creationist movie Expelled: No Intelligence Allowed. These claims are widely criticized within the academic community. The Anti-Defamation League has rejected such attempts to link Darwin's ideas with Nazi atrocities, and has stated that "Using the Holocaust in order to tarnish those who promote the theory of evolution is outrageous and trivializes the complex factors that led to the mass extermination of European Jewry."
Similar criticisms are sometimes applied (or misapplied) to other political or scientific theories that resemble social Darwinism, for example criticisms leveled at evolutionary psychology. For example, a critical reviewer of Weikart's book writes that "(h)is historicization of the moral framework of evolutionary theory poses key issues for those in sociobiology and evolutionary psychology, not to mention bioethicists, who have recycled many of the suppositions that Weikart has traced."
Contemporary Proponents of Social Darwinism
The concept of social Darwinism and eugenics, by those who attribute the term to themselves, is prevalent within modern Satanism. Social Darwinist ideas are presented throughout The Satanic Bible, authored by Anton LaVey, founder of the Church of Satan and 20th century Satanism. LaVey describes Satanism as "a religion based on the universal traits of man," and humans are described throughout as inherently carnal and animalistic. Each of the seven deadly sins is described as part of human's natural instinct, and are thus advocated. Social Darwinism is particularly noticeable in The Book of Satan, where LaVey uses portions of Ragnar Redbeard's Might is Right, though it also appears throughout in references to man's inherent strength and instinct for self-preservation. LaVeyan Satanism has been described as "institutionalism of Machiavellian self-interest" because of many of these themes. The Church of Satan webpage heading “Satanism: The Feared Religion," by Magus Peter H. Gilmore, states, “...contemporary Satanism[...]is: a brutal religion of elitism and social Darwinism that seeks to re-establish the reign of the able over the idiotic...” and, “Satanists also seek to enhance the laws of nature by concentrating on fostering the practice of eugenics.”
Criticism and controversy
Multiple incompatible definitions
Social Darwinism has many definitions, and some of them are incompatible with each other. As such, social Darwinism has been criticized for being an inconsistent philosophy, which does not lead to any clear political conclusions. For example, The Concise Oxford Dictionary of Politics states:
Part of the difficulty in establishing sensible and consistent usage is that commitment to the biology of natural selection and to 'survival of the fittest' entailed nothing uniform either for sociological method or for political doctrine. A 'social Darwinist' could just as well be a defender of laissez-faire as a defender of state socialism, just as much an imperialist as a domestic eugenist.
Nazism, Eugenics, Fascism, Imperialism
Social Darwinism was predominantly found in laissez-faire societies where the prevailing view was that of an individualist order to society. As such, social Darwinism supposed that human progress would generally favor the most individualistic races, which were those perceived as stronger. A different form of social Darwinism was part of the ideological foundations of Nazism and other fascist movements. This form did not envision survival of the fittest within an individualist order of society, but rather advocated a type of racial and national struggle where the state directed human breeding through eugenics. Names such as "Darwinian collectivism" or "Reform Darwinism" have been suggested to describe these views, in order to differentiate them from the individualist type of social Darwinism.
Some pre-twentieth century doctrines subsequently described as social Darwinism appear to anticipate state imposed eugenics and the race doctrines of Nazism. Critics have frequently linked evolution, Charles Darwin and social Darwinism with racialism, nationalism, imperialism and eugenics, contending that social Darwinism became one of the pillars of fascism and Nazi ideology, and that the consequences of the application of policies of "survival of the fittest" by Nazi Germany eventually created a very strong backlash against the theory.
As mentioned above, social Darwinism has often been linked to nationalism and imperialism. During the age of New Imperialism, the concepts of evolution justified the exploitation of "lesser breeds without the law" by "superior races." To elitists, strong nations were composed of white people who were successful at expanding their empires, and as such, these strong nations would survive in the struggle for dominance. With this attitude, Europeans, except for Christian missionaries, seldom adopted the customs and languages of local people under their empires.
Peter Kropotkin – Mutual Aid: A Factor of Evolution
Peter Kropotkin argued in his 1902 book Mutual Aid: A Factor of Evolution that Darwin did not define the fittest as the strongest, or most clever, but recognized that the fittest could be those who cooperated with each other. In many animal societies, "struggle is replaced by co-operation."
It may be that at the outset Darwin himself was not fully aware of the generality of the factor which he first invoked for explaining one series only of facts relative to the accumulation of individual variations in incipient species. But he foresaw that the term [evolution] which he was introducing into science would lose its philosophical and its only true meaning if it were to be used in its narrow sense only—that of a struggle between separate individuals for the sheer means of existence. And at the very beginning of his memorable work he insisted upon the term being taken in its "large and metaphorical sense including dependence of one being on another, and including (which is more important) not only the life of the individual, but success in leaving progeny." [Quoting Origin of Species, chap. iii, p. 62 of first edition.]
While he himself was chiefly using the term in its narrow sense for his own special purpose, he warned his followers against committing the error (which he seems once to have committed himself) of overrating its narrow meaning. In The Descent of Man he gave some powerful pages to illustrate its proper, wide sense. He pointed out how, in numberless animal societies, the struggle between separate individuals for the means of existence disappears, how struggle is replaced by co-operation, and how that substitution results in the development of intellectual and moral faculties which secure to the species the best conditions for survival. He intimated that in such cases the fittest are not the physically strongest, nor the cunningest, but those who learn to combine so as mutually to support each other, strong and weak alike, for the welfare of the community. "Those communities," he wrote, "which included the greatest number of the most sympathetic members would flourish best, and rear the greatest number of offspring" (2nd edit., p. 163). The term, which originated from the narrow Malthusian conception of competition between each and all, thus lost its narrowness in the mind of one who knew Nature.
Noam Chomsky discussed briefly Kropotkin's views in a July 8, 2011 YouTube video from Renegade Economist, in which he said Kropotkin argued
...the exact opposite [of Social Darwinism]. He argued that on Darwinian grounds, you would expect cooperation and mutual aid to develop leading towards community, workers' control and so on. Well, you know, he didn't prove his point. It's at least as well argued as Herbert Spencer is...
