Herbert Spencer (27 April 1820 – 8 December 1903) was an English philosopher, biologist, anthropologist, sociologist, and prominent classical liberal political theorist of the Victorian era.
Spencer developed an all-embracing conception of evolution as the progressive development of the physical world, biological organisms, the human mind, and human culture and societies. As a polymath, he contributed to a wide range of subjects, including ethics, religion, anthropology, economics, political theory, philosophy, literature, astronomy, biology, sociology, and psychology. During his lifetime he achieved tremendous authority, mainly in English-speaking academia. "The only other English philosopher to have achieved anything like such widespread popularity was Bertrand Russell, and that was in the 20th century." Spencer was "the single most famous European intellectual in the closing decades of the nineteenth century" but his influence declined sharply after 1900: "Who now reads Spencer?" asked Talcott Parsons in 1937.
Spencer is best known for the expression "survival of the fittest", which he coined in Principles of Biology (1864), after reading Charles Darwin's On the Origin of Species. This term strongly suggests natural selection, yet as Spencer extended evolution into realms of sociology and ethics, he also made use of Lamarckism.
Life
Spencer was born in Derby, England, on 27 April 1820, the son of William George Spencer (generally called George). Spencer's father was a religious dissenter who drifted from Methodism to Quakerism,
 and who seems to have transmitted to his son an opposition to all forms
 of authority. He ran a school founded on the progressive teaching 
methods of Johann Heinrich Pestalozzi and also served as Secretary of the Derby Philosophical Society, a scientific society which had been founded in 1783 by Erasmus Darwin, the grandfather of Charles Darwin.
Spencer was educated in empirical science by his father, while 
the members of the Derby Philosophical Society introduced him to 
pre-Darwinian concepts of biological evolution, particularly those of Erasmus Darwin and Jean-Baptiste Lamarck. His uncle, the Reverend Thomas Spencer, vicar of Hinton Charterhouse near Bath, completed Spencer's limited formal education by teaching him some mathematics and physics, and enough Latin
 to enable him to translate some easy texts. Thomas Spencer also 
imprinted on his nephew his own firm free-trade and anti-statist 
political views. Otherwise, Spencer was an autodidact who acquired most 
of his knowledge from narrowly focused readings and conversations with 
his friends and acquaintances.
Both as an adolescent and as a young man, Spencer found it 
difficult to settle to any intellectual or professional discipline. He 
worked as a civil engineer during the railway boom of the late 1830s, 
while also devoting much of his time to writing for provincial journals 
that were nonconformist in their religion and radical in their politics.
 From 1848 to 1853 he served as sub-editor on the free-trade journal The Economist, during which time he published his first book, Social Statics
 (1851), which predicted that humanity would eventually become 
completely adapted to the requirements of living in society with the 
consequential withering away of the state.
Its publisher, John Chapman,
 introduced Spencer to his salon which was attended by many of the 
leading radical and progressive thinkers of the capital, including John Stuart Mill, Harriet Martineau, George Henry Lewes and Mary Ann Evans (George Eliot), with whom he was briefly romantically linked. Spencer himself introduced the biologist Thomas Henry Huxley,
 who would later win fame as 'Darwin's Bulldog' and who remained his 
lifelong friend. However it was the friendship of Evans and Lewes that 
acquainted him with John Stuart Mill's A System of Logic and with Auguste Comte's positivism and which set him on the road to his life's work. He strongly disagreed with Comte.
The first fruit of his friendship with Evans and Lewes was Spencer's second book, Principles of Psychology,
 published in 1855, which explored a physiological basis for psychology.
 The book was founded on the fundamental assumption that the human mind 
was subject to natural laws
 and that these could be discovered within the framework of general 
biology. This permitted the adoption of a developmental perspective not 
merely in terms of the individual (as in traditional psychology), but 
also of the species and the race. Through this paradigm, Spencer aimed 
to reconcile the associationist psychology of Mill's Logic,
 the notion that human mind was constructed from atomic sensations held 
together by the laws of the association of ideas, with the apparently 
more 'scientific' theory of phrenology, which located specific mental functions in specific parts of the brain.
As a young man
Spencer argued that both these theories were partial accounts of the 
truth: repeated associations of ideas were embodied in the formation of 
specific strands of brain tissue, and these could be passed from one 
generation to the next by means of the Lamarckian mechanism of use-inheritance. The Psychology, he believed, would do for the human mind what Isaac Newton had done for matter.
 However, the book was not initially successful and the last of the 251 
copies of its first edition was not sold until June 1861.
Spencer's interest in psychology derived from a more fundamental concern which was to establish the universality of natural law.
 In common with others of his generation, including the members of 
Chapman's salon, he was possessed with the idea of demonstrating that it
 was possible to show that everything in the universe – including human 
culture, language, and morality – could be explained by laws of 
universal validity. This was in contrast to the views of many 
theologians of the time who insisted that some parts of creation, in 
particular the human soul, were beyond the realm of scientific 
investigation. Comte's Système de Philosophie Positive had been 
written with the ambition of demonstrating the universality of natural 
law, and Spencer was to follow Comte in the scale of his ambition. 
However, Spencer differed from Comte in believing it was possible to 
discover a single law of universal application which he identified with 
progressive development and was to call the principle of evolution.
In 1858 Spencer produced an outline of what was to become the 
System of Synthetic Philosophy. This immense undertaking, which has few 
parallels in the English language, aimed to demonstrate that the 
principle of evolution applied in biology, psychology, sociology 
(Spencer appropriated Comte's term for the new discipline) and morality.
 Spencer envisaged that this work of ten volumes would take twenty years
 to complete; in the end it took him twice as long and consumed almost 
all the rest of his long life. 
Despite Spencer's early struggles to establish himself as a 
writer, by the 1870s he had become the most famous philosopher of the 
age.
 His works were widely read during his lifetime, and by 1869 he was able
 to support himself solely on the profit of book sales and on income 
from his regular contributions to Victorian periodicals which were 
collected as three volumes of Essays. His works were translated 
into German, Italian, Spanish, French, Russian, Japanese and Chinese, 
and into many other languages and he was offered honours and awards all 
over Europe and North America. He also became a member of the Athenaeum, an exclusive Gentleman's Club in London open only to those distinguished in the arts and sciences, and the X Club, a dining club of nine founded by T.H. Huxley
 that met every month and included some of the most prominent thinkers 
of the Victorian age (three of whom would become presidents of the Royal Society). 
Members included physicist-philosopher John Tyndall and Darwin's cousin, the banker and biologist Sir John Lubbock. There were also some quite significant satellites such as liberal clergyman Arthur Stanley, the Dean of Westminster; and guests such as Charles Darwin and Hermann von Helmholtz
 were entertained from time to time. Through such associations, Spencer 
had a strong presence in the heart of the scientific community and was 
able to secure an influential audience for his views. Despite his 
growing wealth and fame he never owned a house of his own.
The last decades of Spencer's life were characterized by growing 
disillusionment and loneliness. He never married, and after 1855 was a 
perpetual hypochondriac who complained endlessly of pains and maladies that no physician could diagnose at that time.
 By the 1890s his readership had begun to desert him while many of his 
closest friends died and he had come to doubt the confident faith in 
progress that he had made the center-piece of his philosophical system. 
His later years were also ones in which his political views became 
increasingly conservative. Whereas Social Statics had been the 
work of a radical democrat who believed in votes for women (and even for
 children) and in the nationalisation of the land to break the power of 
the aristocracy, by the 1880s he had become a staunch opponent of female
 suffrage and made common cause with the landowners of the Liberty and Property Defence League against what they saw as the drift towards 'socialism' of elements (such as Sir William Harcourt) within the administration of William Ewart Gladstone
 – largely against the opinions of Gladstone himself. Spencer's 
political views from this period were expressed in what has become his 
most famous work, The Man Versus the State. 
Tomb of Herbert Spencer in Highgate Cemetery
The exception to Spencer's growing conservativism was that he remained throughout his life an ardent opponent of imperialism and militarism. His critique of the Boer War was especially scathing, and it contributed to his declining popularity in Britain.
Spencer also invented a precursor to the modern paper clip, though it looked more like a modern cotter pin.
 This "binding-pin" was distributed by Ackermann & Company. Spencer 
shows drawings of the pin in Appendix I (following Appendix H) of his 
autobiography along with published descriptions of its uses.
In 1902, shortly before his death, Spencer was nominated for the Nobel Prize for literature, that was assigned to the German Theodor Mommsen.
 He continued writing all his life, in later years often by dictation, 
until he succumbed to poor health at the age of 83. His ashes are 
interred in the eastern side of London's Highgate Cemetery facing Karl Marx's grave. At Spencer's funeral the Indian nationalist leader Shyamji Krishnavarma announced a donation of £1,000 to establish a lectureship at Oxford University in tribute to Spencer and his work.
Synthetic philosophy
The basis for Spencer's appeal to many of his generation was that he 
appeared to offer a ready-made system of belief which could substitute 
for conventional religious faith at a time when orthodox creeds were 
crumbling under the advances of modern science. Spencer's philosophical 
system seemed to demonstrate that it was possible to believe in the 
ultimate perfection of humanity on the basis of advanced scientific 
conceptions such as the first law of thermodynamics and biological evolution.
In essence Spencer's philosophical vision was formed by a combination of deism
 and positivism. On the one hand, he had imbibed something of eighteenth
 century deism from his father and other members of the Derby 
Philosophical Society and from books like George Combe's immensely popular The Constitution of Man
 (1828). This treated the world as a cosmos of benevolent design, and 
the laws of nature as the decrees of a 'Being transcendentally kind.' 
Natural laws were thus the statutes of a well governed universe that had
 been decreed by the Creator with the intention of promoting human 
happiness. Although Spencer lost his Christian faith as a teenager and 
later rejected any 'anthropomorphic' conception of the Deity, he 
nonetheless held fast to this conception at an almost sub-conscious 
level. At the same time, however, he owed far more than he would ever 
acknowledge to positivism, in particular in its conception of a 
philosophical system as the unification of the various branches of 
scientific knowledge. He also followed positivism in his insistence that
 it was only possible to have genuine knowledge of phenomena and hence 
that it was idle to speculate about the nature of the ultimate reality. 
The tension between positivism and his residual deism ran through the 
entire System of Synthetic Philosophy.
Spencer followed Comte in aiming for the unification of 
scientific truth; it was in this sense that his philosophy aimed to be 
'synthetic.' Like Comte, he was committed to the universality of natural
 law, the idea that the laws of nature applied without exception, to the
 organic realm as much as to the inorganic, and to the human mind as 
much as to the rest of creation. The first objective of the Synthetic 
Philosophy was thus to demonstrate that there were no exceptions to 
being able to discover scientific explanations, in the form of natural 
laws, of all the phenomena of the universe. Spencer's volumes on 
biology, psychology, and sociology were all intended to demonstrate the 
existence of natural laws in these specific disciplines. Even in his 
writings on ethics, he held that it was possible to discover 'laws' of 
morality that had the status of laws of nature while still having 
normative content, a conception which can be traced to George Combe's Constitution of Man.
The second objective of the Synthetic Philosophy was to show that
 these same laws led inexorably to progress. In contrast to Comte, who 
stressed only the unity of scientific method, Spencer sought the 
unification of scientific knowledge in the form of the reduction of all 
natural laws to one fundamental law, the law of evolution. In this 
respect, he followed the model laid down by the Edinburgh publisher Robert Chambers in his anonymous Vestiges of the Natural History of Creation (1844). Although often dismissed as a lightweight forerunner of Charles Darwin's The Origin of Species, Chambers' book was in reality a program for the unification of science which aimed to show that Laplace's nebular hypothesis
 for the origin of the solar system and Lamarck's theory of species 
transformation were both instances (in Lewes' phrase) of 'one 
magnificent generalization of progressive development.' Chambers was 
associated with Chapman's salon and his work served as the 
unacknowledged template for the Synthetic Philosophy.
Evolution
Spencer first articulated his evolutionary perspective in his essay, 'Progress: Its Law and Cause', published in Chapman's Westminster Review in 1857, and which later formed the basis of the First Principles of a New System of Philosophy (1862). In it he expounded a theory of evolution which combined insights from Samuel Taylor Coleridge's essay 'The Theory of Life' – itself derivative from Friedrich von Schelling's Naturphilosophie – with a generalization of von Baer's
 law of embryological development. Spencer posited that all structures 
in the universe develop from a simple, undifferentiated, homogeneity to a
 complex, differentiated, heterogeneity, while being accompanied by a 
process of greater integration of the differentiated parts. This 
evolutionary process could be found at work, Spencer believed, 
throughout the cosmos. It was a universal law, that was applying to the 
stars and the galaxies as much as to biological organisms, and to human 
social organization as much as to the human mind. It differed from other
 scientific laws only by its greater generality, and the laws of the 
special sciences could be shown to be illustrations of this principle.
However, as Bertrand Russell stated in a letter to Beatrice Webb in 1923, this formulation has problems: 'I don't know whether [Spencer] was ever made to realise the implications of the second law of thermodynamics;
 if so, he may well be upset. The law says that everything tends to 
uniformity and a dead level, diminishing (not increasing) 
heterogeneity'.
Spencer's attempt to explain the evolution of complexity was radically different from that to be found in Darwin's Origin of Species
 which was published two years later. Spencer is often, quite 
erroneously, believed to have merely appropriated and generalized 
Darwin's work on natural selection. But although after reading Darwin's work he coined the phrase 'survival of the fittest' as his own term for Darwin's concept,
 and is often misrepresented as a thinker who merely applied the 
Darwinian theory to society, he only grudgingly incorporated natural 
selection into his preexisting overall system. The primary mechanism of 
species transformation that he recognized was Lamarckian
 use-inheritance which posited that organs are developed or are 
diminished by use or disuse and that the resulting changes may be 
transmitted to future generations. Spencer believed that this 
evolutionary mechanism was also necessary to explain 'higher' evolution,
 especially the social development of humanity. Moreover, in contrast to
 Darwin, he held that evolution had a direction and an end-point, the 
attainment of a final state of equilibrium. He tried to apply the theory
 of biological evolution to sociology. He proposed that society was the 
product of change from lower to higher forms, just as in the theory of 
biological evolution, the lowest forms of life are said to be evolving 
into higher forms. Spencer claimed that man's mind had evolved in the 
same way from the simple automatic responses of lower animals to the 
process of reasoning in the thinking man. Spencer believed in two kinds 
of knowledge: knowledge gained by the individual and knowledge gained by
 the race. Intuition, or knowledge learned unconsciously, was the 
inherited experience of the race. 
Spencer in his book Principles of Biology (1864), proposed a pangenesis
 theory that involved "physiological units" assumed to be related to 
specific body parts and responsible for the transmission of 
characteristics to offspring. These hypothetical hereditary units were 
similar to Darwin's gemmules.
Sociology
In his 70s
Spencer read with excitement the original positivist sociology of Auguste Comte. A philosopher of science, Comte had proposed a theory of socio-cultural evolution that society progresses by a general law of three stages.
 Writing after various developments in biology, however, Spencer 
rejected what he regarded as the ideological aspects of Comte's 
positivism, attempting to reformulate social science in terms of his 
principle of evolution, which he applied to the biological, 
psychological and sociological aspects of the universe. 
Given the primacy which Spencer placed on evolution, his sociology might be described as social Darwinism mixed with Lamarckism.
  However, despite its popularity, this view of Spencer's sociology is 
mistaken.  While his political and ethical writings had themes 
consistent with social Darwinism, such themes are absent in Spencer's 
sociological works, which focus on how processes of societal growth and 
differentiation lead to changing degrees of complexity in social 
organization.
The evolutionary progression from simple, undifferentiated 
homogeneity to complex, differentiated heterogeneity was exemplified, 
Spencer argued, by the development of society. He developed a theory of 
two types of society, the militant and the industrial, which 
corresponded to this evolutionary progression. Militant society, 
structured around relationships of hierarchy and obedience, was simple 
and undifferentiated; industrial society, based on voluntary, 
contractually assumed social obligations, was complex and 
differentiated. Society, which Spencer conceptualized as a 'social organism'
 evolved from the simpler state to the more complex according to the 
universal law of evolution. Moreover, industrial society was the direct 
descendant of the ideal society developed in Social Statics, 
although Spencer now equivocated over whether the evolution of society 
would result in anarchism (as he had first believed) or whether it 
pointed to a continued role for the state, albeit one reduced to the 
minimal functions of the enforcement of contracts and external defense. 
Though Spencer made some valuable contributions to early sociology, not least in his influence on structural functionalism,
 his attempt to introduce Lamarckian or Darwinian ideas into the realm 
of sociology was unsuccessful. It was considered by many, furthermore, 
to be actively dangerous. Hermeneuticians of the period, such as Wilhelm Dilthey, would pioneer the distinction between the natural sciences (Naturwissenschaften) and human sciences (Geisteswissenschaften). In the United States, the sociologist Lester Frank Ward, who would be elected as the first president of the American Sociological Association,
 launched a relentless attack on Spencer's theories of laissez-faire and
 political ethics. Although Ward admired much of Spencer's work he 
believed that Spencer's prior political biases had distorted his thought
 and had led him astray. In the 1890s, Émile Durkheim established formal academic sociology with a firm emphasis on practical social research.  By the turn of the 20th century the first generation of German sociologists, most notably Max Weber, had presented methodological antipositivism.
 However, it should be noted that Spencer's theories of laissez-faire, 
survival-of-the-fittest and minimal human interference in the processes 
of natural law had an enduring and even increasing appeal in the social 
science fields of economics and political science, and one writer has 
recently made the case for Spencer's importance for a sociology that 
must learn to take energy in society seriously.
Agnosticism
Spencer's
 reputation among the Victorians owed a great deal to his agnosticism. 
He rejected theology as representing the 'impiety of the pious.' He was 
to gain much notoriety from his repudiation of traditional religion, and
 was frequently condemned by religious thinkers for allegedly advocating
 atheism and materialism. Nonetheless, unlike Thomas Henry Huxley, whose agnosticism was a militant creed directed at 'the unpardonable sin of faith' (in Adrian Desmond's
 phrase), Spencer insisted that he was not concerned to undermine 
religion in the name of science, but to bring about a reconciliation of 
the two. The following argument is a summary of Part 1 of his First Principles (2nd ed 1867).
Starting either from religious belief or from science, Spencer 
argued, we are ultimately driven to accept certain indispensable but 
literally inconceivable notions. Whether we are concerned with a Creator
 or the substratum which underlies our experience of phenomena, we can 
frame no conception of it. Therefore, Spencer concluded, religion and 
science agree in the supreme truth that the human understanding is only 
capable of 'relative' knowledge. This is the case since, owing to the 
inherent limitations of the human mind, it is only possible to obtain 
knowledge of phenomena, not of the reality ('the absolute') underlying 
phenomena. Hence both science and religion must come to recognise as the
 'most certain of all facts that the Power which the Universe manifests 
to us is utterly inscrutable.' He called this awareness of 'the 
Unknowable' and he presented worship of the Unknowable as capable of 
being a positive faith which could substitute for conventional religion.
 Indeed, he thought that the Unknowable represented the ultimate stage 
in the evolution of religion, the final elimination of its last 
anthropomorphic vestiges.
Political views
Spencerian views in 21st century circulation derive from his 
political theories and memorable attacks on the reform movements of the 
late 19th century. He has been claimed as a precursor by libertarians and anarcho-capitalists. Economist Murray Rothbard called Social Statics "the greatest single work of libertarian political philosophy ever written."
 Spencer argued that the state was not an "essential" institution and 
that it would "decay" as voluntary market organization would replace the
 coercive aspects of the state. He also argued that the individual had a "right to ignore the state."
 As a result of this perspective, Spencer was harshly critical of 
patriotism. In response to being told that British troops were in danger
 during the Second Afghan War
 (1878-1880) he replied: "When men hire themselves out to shoot other 
men to order, asking nothing about the justice of their cause, I don't 
care if they are shot themselves."
Politics in late Victorian Britain moved in directions that 
Spencer disliked, and his arguments provided so much ammunition for 
conservatives and individualists in Europe and America that they are 
still in use in the 21st century. The expression 'There is no alternative' (TINA), made famous by Prime Minister Margaret Thatcher, may be traced to its emphatic use by Spencer.
By the 1880s he was denouncing "the new Toryism" (that is, the 
"social reformist wing" of the Liberal party – the wing to some extent 
hostile to Prime Minister William Ewart Gladstone,
 this faction of the Liberal party Spencer compared to the 
interventionist "Toryism" of such people as the former Conservative 
party Prime Minister Benjamin Disraeli). In The Man versus the State (1884),
 he attacked Gladstone and the Liberal party for losing its proper 
mission (they should be defending personal liberty, he said) and instead
 promoting paternalist social legislation (what Gladstone himself called
 "Construction" – an element in the modern Liberal party that he 
opposed). Spencer denounced Irish land reform, compulsory education, 
laws to regulate safety at work, prohibition and temperance laws, tax 
funded libraries, and welfare reforms. His main objections were 
threefold: the use of the coercive powers of the government, the 
discouragement given to voluntary self-improvement, and the disregard of
 the "laws of life." The reforms, he said, were tantamount to 
"socialism", which he said was about the same as "slavery" in terms of 
limiting human freedom. Spencer vehemently attacked the widespread 
enthusiasm for annexation of colonies and imperial expansion, which 
subverted all he had predicted about evolutionary progress from 
'militant' to 'industrial' societies and states.
Spencer anticipated many of the analytical standpoints of later libertarian theorists such as Friedrich Hayek,
 especially in his "law of equal liberty", his insistence on the limits 
to predictive knowledge, his model of a spontaneous social order, and 
his warnings about the "unintended consequences" of collectivist social 
reforms.
While often caricatured as ultra-conservative, Spencer had been 
more radical earlier in his career – opposing private property in land 
and claiming that each person has a latent claim to participate in the 
use of the earth (views that influenced Georgism), calling himself "a radical feminist"
 and advocating the organization of trade unions as a bulwark against 
"exploitation by bosses", and favored an economy organized primarily in
 free worker co-operatives as a replacement for wage-labor.
 Although he retained support for unions, his views on the other issues 
had changed by the 1880s. He came to predict that social welfare 
programs would eventually lead to socialization of the means of 
production, saying "all socialism is slavery"; Spencer defined a slave 
as a person who "labours under coercion to satisfy another's desires" 
and believed that under socialism or communism the individual would be 
enslaved to the whole community rather than to a particular master, and 
"it means not whether his master a single person or society"
Social Darwinism
For many, the name of Herbert Spencer would be virtually synonymous with Social Darwinism,
 a social theory that applies the law of the survival of the fittest to 
society; humanitarian impulses had to be resisted as nothing should be 
allowed to interfere with nature's laws, including the social struggle 
for existence.
Spencer's association with Social Darwinism
 might have its origin in a specific interpretation of his support for 
competition. Whereas in biology the competition of various organisms can
 result in the death of a species or organism, the kind of competition 
Spencer advocated is closer to the one used by economists, where 
competing individuals or firms improve the well being of the rest of 
society. Spencer viewed private charity positively, encouraging both 
voluntary association and informal care to aid those in need, rather 
than relying on government bureaucracy or force. He further recommended 
that private charitable efforts would be wise to avoid encouraging the 
formation of new dependent families by those unable to support 
themselves without charity.
Focusing on the form as well as the content of Spencer's 
"Synthetic Philosophy", one writer has identified it as the paradigmatic
 case of "Social Darwinism", understood as a politically motivated 
metaphysic very different in both form and motivation from Darwinist 
science.
General influence
While
 most philosophers fail to achieve much of a following outside the 
academy of their professional peers, by the 1870s and 1880s Spencer had 
achieved an unparalleled popularity, as the sheer volume of his sales 
indicate. He was probably the first, and possibly the only, philosopher 
in history to sell over a million copies of his works during his own 
lifetime. In the United States, where pirated editions were still 
commonplace, his authorized publisher, Appleton, sold 368,755 copies 
between 1860 and 1903. This figure did not differ much from his sales in
 his native Britain, and once editions in the rest of the world are 
added in the figure of a million copies seems like a conservative 
estimate. As William James
 remarked, Spencer "enlarged the imagination, and set free the 
speculative mind of countless doctors, engineers, and lawyers, of many 
physicists and chemists, and of thoughtful laymen generally." The aspect of his thought that emphasized individual self-improvement found a ready audience in the skilled working class. 
Spencer's influence among leaders of thought was also immense, 
though it was most often expressed in terms of their reaction to, and 
repudiation of, his ideas. As his American follower John Fiske observed, Spencer's ideas were to be found "running like the weft through all the warp" of Victorian thought. Such varied thinkers as Henry Sidgwick, T.H. Green, G.E. Moore, William James, Henri Bergson, and Émile Durkheim defined their ideas in relation to his. Durkheim's Division of Labour in Society
 is to a very large extent an extended debate with Spencer, from whose 
sociology, many commentators now agree, Durkheim borrowed extensively.
Portrait of Spencer by Hamilton, ca. 1895
In post-1863-Uprising Poland, many of Spencer's ideas became integral to the dominant fin-de-siècle ideology, "Polish Positivism". The leading Polish writer of the period, Bolesław Prus, hailed Spencer as "the Aristotle of the nineteenth century" and adopted Spencer's metaphor of society-as-organism, giving it a striking poetic presentation in his 1884 micro-story, "Mold of the Earth", and highlighting the concept in the introduction to his most universal novel, Pharaoh (1895).
The early 20th century was hostile to Spencer. Soon after his 
death, his philosophical reputation went into a sharp decline. Half a 
century after his death, his work was dismissed as a "parody of 
philosophy", and the historian Richard Hofstadter called him "the metaphysician of the homemade intellectual, and the prophet of the cracker-barrel agnostic." Nonetheless, Spencer's thought had penetrated so deeply into the Victorian age that his influence did not disappear entirely.
In recent years, much more positive estimates have appeared, as well as a still highly negative estimate.
Political influence
Despite
 his reputation as a Social Darwinist, Spencer's political thought has 
been open to multiple interpretations. His political philosophy could 
both provide inspiration to those who believed that individuals were 
masters of their fate, who should brook no interference from a meddling 
state, and those who believed that social development required a strong 
central authority. In Lochner v. New York, conservative justices of the United States Supreme Court
 could find inspiration in Spencer's writings for striking down a New 
York law limiting the number of hours a baker could work during the 
week, on the ground that this law restricted liberty of contract. Arguing against the majority's holding that a "right to free contract" is implicit in the due process clause of the Fourteenth Amendment, Oliver Wendell Holmes Jr.
 wrote: "The Fourteenth Amendment does not enact Mr. Herbert Spencer's 
Social Statics." Spencer has also been described as a quasi-anarchist, as well as an outright anarchist. Marxist theorist Georgi Plekhanov, in his 1909 book Anarchism and Socialism, labelled Spencer a "conservative Anarchist."
Spencer's ideas became very influential in China and Japan 
largely because he appealed to the reformers' desire to establish a 
strong nation-state with which to compete with the Western powers. His 
thought was introduced by the Chinese scholar Yen Fu, who saw his writings as a prescription for the reform of the Qing state. Spencer also influenced the Japanese Westernizer Tokutomi Soho,
 who believed that Japan was on the verge of transitioning from a 
"militant society" to an "industrial society," and needed to quickly 
jettison all things Japanese and take up Western ethics and learning. He also corresponded with Kaneko Kentaro, warning him of the dangers of imperialism. Savarkar writes in his Inside the Enemy Camp, about reading all of Spencer's works, of his great interest in them, of their translation into Marathi, and their influence on the likes of Tilak and Agarkar, and the affectionate sobriquet given to him in Maharashtra – Harbhat Pendse.
Influence on literature
Spencer greatly influenced literature and rhetoric. His 1852 essay, "The Philosophy of Style", explored a growing trend of formalist
 approaches to writing. Highly focused on the proper placement and 
ordering of the parts of an English sentence, he created a guide for 
effective composition. Spencer aimed to free prose writing from as much "friction and inertia"
 as possible, so that the reader would not be slowed by strenuous 
deliberations concerning the proper context and meaning of a sentence. 
Spencer argued that writers should aim "To so present ideas that they 
may be apprehended with the least possible mental effort" by the reader. 
He argued that by making the meaning as readily accessible as 
possible, the writer would achieve the greatest possible communicative 
efficiency. This was accomplished, according to Spencer, by placing all 
the subordinate clauses, objects and phrases before the subject of a 
sentence so that, when readers reached the subject, they had all the 
information they needed to completely perceive its significance. While 
the overall influence that "The Philosophy of Style" had on the field of
 rhetoric was not as far-reaching as his contribution to other fields, 
Spencer's voice lent authoritative support to formalist views of rhetoric. 
Spencer influenced literature inasmuch as many novelists and short story authors came to address his ideas in their work. George Eliot, Leo Tolstoy, Thomas Hardy, George Bernard Shaw, Bolesław Prus, Abraham Cahan, D. H. Lawrence, Machado de Assis, Richard Austin Freeman, and Jorge Luis Borges all referenced Spencer. Arnold Bennett greatly praised First Principles, and the influence it had on Bennett may be seen in his many novels. Jack London went so far as to create a character, Martin Eden, a staunch Spencerian. It has also been suggested that the character of Vershinin in Anton Chekhov's play The Three Sisters is a dedicated Spencerian. H.G. Wells used Spencer's ideas as a theme in his novella, The Time Machine, employing them to explain the evolution of man into two species. It is perhaps the best testimony to the influence
 of Spencer's beliefs and writings that his reach was so diverse. He 
influenced not only the administrators who shaped their societies' inner
 workings, but also the artists who helped shape those societies' ideals
 and beliefs. In Rudyard Kipling's novel Kim,
 the Anglophile Bengali spy Hurree Babu admires of Herbert Spencer and 
quotes him to comic effect: "They are, of course, dematerialised 
phenomena.  Spencer says." "I am good enough Herbert Spencerian, I 
trust, to meet little thing like death, which is all in my fate, you 
know." "He thanked all the Gods of Hindustan, and Herbert Spencer, that 
there remained some valuables to steal."
