Herbert Spencer (27 April 1820 – 8 December 1903) was an English philosopher, prominent classical liberal political theorist, and sociological 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, economics, politics, philosophy, biology, sociology, and psychology. During his lifetime he achieved tremendous authority, mainly in English Speaking circles. Indeed in Britain and the United States at "one time Spencer's disciples had not blushed to compare him with Aristotle!"[1] He is best known for coining the phrase "survival of the fittest," which he did in Principles of Biology (1864), after reading Charles Darwin's On the Origin of Species.[2] This term strongly suggests natural selection, yet as Spencer extended evolution into realms of sociology and ethics, he made use of Lamarckism rather than natural selection. Herbert 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 the 1790s by Erasmus Darwin, the grandfather of Charles. 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 firmly 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.[3] As both an adolescent and 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 shortly become completely adapted to the requirements of living in society with the consequential withering away of the state. Its publisher, John Chapman, introduced him 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.[4] 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. 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 modestly believed, would do for the human mind what Isaac Newton had done for matter.[5] 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[6]. 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 Systeme 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[7]. 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 honors 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. 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 nationalization 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 'socialism' of the administration of William Ewart Gladstone. Spencer's political views from this period were expressed in what has become his most famous work, The Man versus the State. 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.[8] In 1902, shortly before his death, Spencer was nominated for the Nobel Prize for literature. 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.[9] 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.
