Degeneration theory was a widely influential concept in the social and biological sciences in the nineteenth century[1][2][3] and derived from pre-scientific and erroneous concepts of heredity. The theory of degeneration started life in relation to ethnicity and the origins of the human races; it then (from the 1850s) became popular with public health anxieties concerning psychiatry and criminology; and finally (in the 1890s) migrated into general cultural criticism. The meaning of degeneration was poorly defined but may be regarded as an organic change from more complex to simpler, less differentiated forms - and degeneration theory attempted to locate explanations for social change in physical (biological) systems. As the nineteenth century progressed, the increasing popularity of "degeneration" reflected an anxious pessimism about the future of European/Western civilization. However, something of a paradox rests with the fact that, at the climax of its achievements, several of Europe's leading thinkers became preoccupied with the details of its possible decline and collapse.
The concept of degeneration first arose with an increasing awareness of social and historical processes in the European Enlightenment. Several main influences seem to have been involved.
The first related to the extreme demographic upheavals - including urbanization - occasioned by the industrial revolution in the early years of the nineteenth century. The disturbing experience of social change - and urban crowds - entirely unusual in the agrarian eighteenth century - was recorded in the novels of Charles Dickens and by early writers on social psychology, including Gustav Le Bon and Georg Simmel. Secondly, the proto-evolutionary biology and transformatist speculations of Buffon, Lamarck and other natural historians - taken together with the Baron von Cuvier's catastrophic theory of extinctions - played a decisive role in establishing a sense of the unsettled nature of human society - including the possibility of an evolutionary reversion - or dissolution. Thirdly, the activities of world trade and colonialism - the early European experience of globalization - confirmed a new awareness of the unusual fragility of western civilization. Fourthly, the growth of historical scholarship in the eighteenth century - exemplified by Edward Gibbon's The History of the Decline and Fall of The Roman Empire (1776-1789) - excited a renewed interest in the circumstances of historical decline. Finally, the brutal downfall of the French aristocracy in the revolution of 1789 demonstrated the very temporary nature of the customary relations of civilized discourse.
Degeneration theory achieved a detailed articulation in Benedict Morel's (1857) Treatise on Degeneration - a complicated piece of clinical commentary from an asylum in Normandy which coalesced - in the public imagination at least - with de Gobineau's (1855) Essay on The Inequality of the Human Races - a bizarre and pseudoscientific treatise from a romantic novelist manqué . Morel's concept of hereditary degeneracy was later amplified by Cesare Lombroso with the notion of atavistic retrogression in his exposition of the Italian school's concept of criminal anthropology. In England, degeneration received a scientific formulation at the hand of Ray Lankester in 1880, while the psychiatrist Henry Maudsley maintained a rather ambiguous attitude to degeneration, being initially quite dismissive, but latterly more pessimistic about degeneration in the British population.
In the fin-de-siècle period, Max Nordau scored an unexpected success with his bestselling Degeneration (1892) - an enormous work of cultural criticism and gloomy nostalgia. Sigmund Freud (who met Nordau while studying in Paris - and was decidedly unimpressed) was notably hostile to the degeneration concept which fell from popular and fashionable favour around the time of the First World War - although many of its preoccupations lingered in the writings of the eugenicists and social Darwinists. Oswald Spengler's (1919) The Decline of The West captured something of the degenerationist spirit in the aftermath of the war.
"What conception of dégénérescence was produced in Morel's famous treatise of 1857? The term was applied to patterns of heredity in societies and, specifically, to deviations from the 'normal type' of humanity....Morel pulled together a bewildering array of physical conditions, moral and social habits; from hernias, goitres and pointed ears....he explored disturbances of the intellectual faculties and the noxious tendencies of certain forms of romanticism which resulted in languorous desires, effeteness, reveries, impotence, suicidal tendencies, inertia, melancholy and apathy. For Morel, the human being was a unified ensemble, composed of matter and of spirit. Physical degeneration could not but lead to intellectual and moral collapse, and vice versa. Degénéréscence was the name for a process of pathological change from one condition to another in society and in the body...." Daniel Pick (1989) Faces of Degeneration.
"Any new set of conditions which render a species' food and safety very easily obtained, seem to lead to degeneration..." E. Ray Lankester (1880) Degeneration: A Chapter in Darwinism.
"The word degenerate, when applied to a people, means that the people no longer has the same intrinsic value as it had before, because it has no longer the same blood in its veins, continual adulterations having gradually affected the quality of that blood....in fact, the man of a decadent time, the degenerate man, properly so-called, is a different being, from the racial point of view, from the heroes of the great ages....I think I am right in concluding that the human race in all its branches has a secret repulsion from the crossing of blood...." Arthur de Gobineau (1855) Essay on The Inequality of the Human Races.
"Nordau argued that madness, suicide, crime and pathological literature symptomatized modern times - "We stand now in the midst of a severe mental epidemic; of a sort of black death of degeneration and hysteria...." Having borrowed various contemporary terms and ideas from the works of Morel, Lombroso, Maudsley, Taine, Charcot, and others, Nordau argued that modern society was witnessing a terrible crisis borne out of the growing division between the human body and social conditions...." Daniel Pick (1989) Faces of Degeneration.
"Sexual contagion: In other words, while degeneration was technically a medical term, and denoted a particular sub-category of organic disease, this disease wrought moral effects by inducing in the human organism a "morbid deviation from the original type" whose offspring were congenitally prone....to sinful behaviours. Symptoms became increasingly confused with causes...." Kelly Hurley (1996) The Gothic Body.
The earliest uses of the term "degeneration" are to be found in the writings of Blumenbach and Buffon at the end of the eighteenth century, when these early writers on natural history considered scientific approaches to the human species. With the taxonomic mind-set of natural historians, they drew attention to the different ethnic groupings of mankind, and raised general enquiries about their relationships - with the idea that racial groupings are to be explained by environmental insults to a common ancestral stock.
The theory of degeneration found its first real articulation in the writings of Benedict Morel (1809-1873) - and especially in his Traité des dégénérescences physiques, intellectuelles et morales de l'espèce humaine (1857). Morel was a highly regarded psychiatrist, the very successful superintendent of the Rouen asylum for almost twenty years, and a fastidious recorder of the family histories of his variously disabled patients. Through the details of these family histories, Morel discerned an hereditarian line of defective parents infected by pollutants and stimulants; a subsequent generation liable to epilepsy, neurasthenia and hysteria; a third generation prone to insanity; and a final generation doomed to congenital idiocy and sterility. Morel (in 1857) proposed a theory of hereditary degeneracy, bringing together environmental and hereditary elements in an uncompromisingly pre-Darwinian mix. Morel's contribution was further advocated by Valentin Magnan (1835-1916), who stressed the role of alcohol - particularly absinthe - in the generation of psychiatric disorders.
Morel's work was taken up - and greatly expanded in the Darwinian period - by the Italian medical scientist Cesare Lombroso (1835-1909). In his L'uomo delinquente (1876), Lombroso outlined a comprehensive natural history of the socially deviant person and he detailed the stigmata of the person who was born to be "criminally insane". These included a low, sloping forehead; hard and shifty eyes; large, handle-shaped ears; a flattened or upturned nose; a forward projection of the jaw; irregular teeth; large middle incisors; prehensile toes and feet and long simian arms; and a scanty beard and baldness. Lombroso, with his concept of atavistic retrogression, suggested an evolutionary reversion, complementing "hereditary degeneracy" - and his work with the medical examination of criminals in Turin resulted in his theory of criminal anthropology - a constitutional notion of abnormal personality - actually unsupported by his own scientific investigations.
In 1896, Max Nordau - an expatriate Hungarian Zionist living in Paris - published his extraordinary bestseller Degeneration (Entartung) which greatly extended the concepts of Benedict Morel and Cesare Lombroso (to whom he dedicated the book) to the entire civilization of western Europe - and transformed the medical connotations of degeneration to a generalized cultural criticism. Adopting some of Charcot's neurological jargon, Nordau identified a number of weaknesses in contemporary western culture which he characterized in terms of "ego-mania" - i.e. narcissism and hysteria. Degeneration theory fell from favour around the time of the First World War, partly because of the increasing vogue for psychoanalysis - and psychoanalytic styles of interpretation - though many of its preoccupations lived on in the world of eugenics and social Darwinism.
Towards the close of the nineteenth century, in the fin-de-siècle, something of an obsession with decline, descent and degeneration invaded the European creative imagination, partly fuelled by a widespread miscomprehension of Darwinian evolutionary theory. Among the main literary examples are Robert Louis Stevenson's Strange Case of Dr Jekyll and Mr Hyde - published in the same year (1886) as Richard von Krafft-Ebing's Psychopathia Sexualis - and, subsequently, Oscar Wilde's only novel (containing his aesthetic manifesto) The Picture of Dorian Gray in 1891. A scientific twist was added by H.G. Wells in The Time Machine (1895) - in which Wells prophesied the splitting of the human race into differently degenerate forms - and again, a little later, in his The Island of Doctor Moreau (1896).
In her influential study The Gothic Body,[4] Kelly Hurley draws attention to the literary device of the abhuman - and to lesser known authors in the field, including Richard Marsh (1857-1915), author of The Beetle (1897) - and William Hope Hodgson (1877-1918), author of The Boats of the Glen Carrig, The House on the Borderland and The Night Land. In 1897, Bram Stoker published Dracula, an enormously influential Gothic novel featuring the immortal vampire Count Dracula. Arthur Conan Doyle's Sherlock Holmes stories included a host of degenerationist tropes, perhaps best illustrated in The Creeping Man.
