Degeneracy theory — in French, dégénérescence — was a medical doctrine that dominated psychiatry and public health across much of the Western world from the 1860s to roughly the 1910s. Its central claim was that families could accumulate hereditary damage across generations: nervous disorder in a grandfather, mental illness in a parent, idiocy in a child, and finally sterility and extinction of the line. The theory was formulated by French asylum physician B. A. Morel in 1857 and rapidly became “received wisdom” in European psychiatry, shaping how doctors classified mental illness, explained therapeutic failure, and justified permanent asylum confinement. Its legacy extended into eugenics programs and eventually — by a long, dark chain of causation — into the compulsory sterilization laws and the Nazi T-4 extermination program of the twentieth century. Understanding degeneracy theory is essential for making sense of why nineteenth-century psychiatry developed as it did, and why its classifications bore the marks they did.
Origins: The Problem Morel Was Solving
To understand why degeneracy theory was so eagerly received, it helps to understand the state of French psychiatry in the 1840s and 1850s. Dowbiggin argues that the theory arose not from any neutral scientific inquiry but from a specific crisis of professional legitimacy.(Ian Dowbiggin, 1991)
French alienists had won important legal privileges under the Law of 30 June 1838, which gave them authority over public asylums. But that law immediately exposed how little they could actually accomplish. Cure rates in French asylums declined from 27.9 percent in 1864 to 24.8 percent in 1874, and asylum populations were dominated by incurable conditions — syphilitic general paresis, alcoholism, and senile dementia.(Ian Dowbiggin, 1991) Pathological anatomy, which had seemed so promising after Bayle and Calmeil found localized brain lesions in the paralytic insane in 1819–1822, failed to reveal lesions for any other form of mental illness.(Ian Dowbiggin, 1991) Psychiatrists had no explanation for most of what they were seeing and no treatments that demonstrably worked.
This scientific inadequacy made professional authority precarious. Because alienists could not prove that insanity was a somatic disease — one that only physicians, not clergymen, were qualified to treat — the Catholic Church retained a credible claim to manage the insane. Clerical nursing orders expanded rapidly after 1815, and departmental prefects often preferred their cheaper institutions.(Ian Dowbiggin, 1991) As Dowbiggin frames it, as long as psychiatrists could not establish that insanity was a physical condition with definable organic pathology, their medical credentials were in doubt, and “clerics were still entitled to diagnose and treat the insane.”(Ian Dowbiggin, 1991)
Hereditarianism, and eventually the fully developed degeneracy theory, was a response to this double bind. Dowbiggin argues that under the pressure of adapting to the shifting cultural climate between 1848 and 1900, alienists developed hereditarian approaches as a way of legitimizing their participation in moral treatment, their role as purveyors of essential medical information, and the existence of the insane asylum itself.(Ian Dowbiggin, 1991) When public attacks on alienism mounted in the 1860s — including campaigns in both liberal and clerical-monarchist newspapers accusing psychiatrists of arbitrary confinement — “asylum psychiatrists began to formulate a hereditarian model of mental disease calculated to convince the imperial government of their expertise and to postpone official inquiries into alienist practice.”(Ian Dowbiggin, 1991)
Morel’s 1857 Formulation
Bénédict Augustin Morel (1809–1873) was born in Vienna, left in the care of French clergy as a child, and came to mental medicine through the influence of the Salpêtrière alienist J. P. Falret after years of poverty in Paris shared with the physiologist Claude Bernard.(Ian Dowbiggin, 1991)
His 1857 Treatise on the Physical, Intellectual, and Moral Degeneracy of the Human Race proposed a model of hereditary mental illness organized in a sequence across generations. Factors such as alcoholism, immorality, poor diet, and unhealthy domestic and occupational conditions produced a “pathological sequence” that marked certain family lineages: neurosis in the first generation, mental alienation in the second, imbecility in the third, idiocy and sterility in the fourth.(Ian Dowbiggin, 1991) The key mechanism was heredity — not the simple transmission of a specific disease, but the transmission of a flawed condition of the entire nervous system, which Morel called a nervous diathesis.(Ian Dowbiggin, 1991) That diathesis could then manifest as any of a range of neurological or psychiatric disturbances depending on circumstances. Scull underlines how rapidly these ideas achieved dominance: within a decade or a decade and a half of 1857, Morel’s ideas were “received wisdom,” reframing the insane from victims of civilization’s stresses to its biological antithesis — a biologically inferior lot whose inferiority was written on their physiognomy.(Andrew Scull, 2015) Porter confirms the theoretical arc: hereditary degeneration was cumulative over generations, descending from neurasthenia through criminality to insanity and sterility, driven by both organic and social factors.(Porter, 1997)
The theological roots of the theory were explicit. Morel was a devout Catholic all his life, and Dowbiggin shows that the degenerative process in his framework was conceived as a deviation from the “primitive type” of the human species — a type Morel equated with the biblical Adam.(Ian Dowbiggin, 1991) Degeneration was, in this sense, the accumulated consequence of the Fall, transmitted biologically across generations. This theological framing was not incidental: it made the theory politically safe under Napoleon III’s clerical Second Empire, at the same moment when French alienists were trying to preserve their state-granted privileges. As Berrios and Porter note, Morel’s dégénérescence “was conceived in explicitly religious terms: it was the cumulative consequence of Adam’s Fall, transmitted and worsening across generations.”(German E. Berrios & Roy Porter (eds.), 1995)
Morel also used the theory to propose a new method of psychiatric classification. In 1860 he argued that alienists should discard the then-standard approach of classifying mental illness by symptom — the system inherited from Pinel and Esquirol — in favor of an etiological classification based on cause. Because heredity could account for many different symptoms, diseases previously classified separately could be grouped together under a single hereditary origin.(Ian Dowbiggin, 1991) This was a genuinely novel move in psychiatric nosology, and it influenced Kraepelin’s later work directly: Porter notes that Kraepelin’s concept of dementia praecox, combining Kahlbaum’s catatonia, Morel’s démence précoce, and Hecker’s hebephrenia, was itself “a degenerative condition” in the Morelian mold.(Porter, 1997)
The French Context: Professional Pressures and the 1838 Law
Scull’s analysis indicates that degeneration theory served alienists’ professional interests by framing therapeutic failure as inevitable and linking madness to physical pathology, thus reinforcing medical authority and legitimizing permanent asylum segregation.(Andrew Scull, 2015) As an ideology, the theory possessed “surpassing virtues” for alienists, which explains its rapid acceptance, and it furnished a renewed justification for isolating the insane in asylums.(Andrew Scull, 2015)
In the French context, several pressures converged to make hereditarianism not just useful but urgent. The political upheavals of 1848–1851 and the subsequent Second Empire created a cultural environment in which the Société médico-psychologique — the first French psychiatric association, formally constituted in 1848 — had little choice but to accommodate both state authority and Catholic orthodoxy.(Ian Dowbiggin, 1991) B. A. Morel himself had written to Guillaume Ferrus in 1845 calling for a French psychiatric association, and Philippe Buchez — a Catholic social reformer and co-founder of the Société — helped shape its accommodationist stance.(Ian Dowbiggin, 1991) When Buchez noted in 1857 that Morel’s conception of heredity “had serious implications for the entire human race,” he was registering the theory’s radicalism within the framework of professional politics rather than denouncing it.(Ian Dowbiggin, 1991)
The antipsychiatric campaign of the 1860s made the professional utility of degeneracy theory even more acute. Journalists across the political spectrum — both Voltairian liberals and Catholic-monarchist papers — attacked the 1838 asylum law and accused alienists of arbitrarily incarcerating citizens. B. A. Morel himself reported in 1864 that “a malaise had gripped the branch of the medical profession that delivered public assistance to the insane.”(Ian Dowbiggin, 1991) In response, alienists increasingly aligned themselves with the language of hereditary science: by attributing the asylum’s permanent population to biologically determined conditions beyond any physician’s power to cure, they converted therapeutic failure from evidence of professional incompetence into evidence of the irreversible nature of the disease itself.
Dowbiggin argues that the imprecision of hereditarianism was a feature, not a bug. “Its imprecision allowed alienists to disguise gaps in psychiatric knowledge, expand diagnostic categories to include ‘lucid aliénés’ and moral deviants, and claim expertise in forensic psychiatry and family hygiene.”(Ian Dowbiggin, 1991) Ulysee Trelat argued in 1856 that psychiatry had been too preoccupied with external causes of insanity and recommended greater recognition of heredity as an internal cause.(Ian Dowbiggin, 1991)
The Lamarckian Foundation
The theory required a mechanism for the transmission of acquired degeneracy across generations. Morel and his successors found that mechanism in Lamarckian biology. The theoretical ground for hereditarianism had been prepared by Prosper Lucas’s 1847–1850 Philosophical and Physiological Treatise on Natural Heredity, which proposed two biological laws: a “law of heredity” perpetuating physical and moral characteristics across generations, and a “law of inneite” representing nature’s capacity to produce spontaneous variations; subsequent alienists largely rejected Lucas’s second law, retaining only the cumulative-damage mechanism.(Ian Dowbiggin, 1991) Darwin’s theory of natural selection made little headway in French science, where there was fierce allegiance to the ideas of the naturalist Jean-Baptiste Lamarck, who held that organisms could inherit characteristics acquired during their lifetime through accommodation to the environment. Dowbiggin argues that “degeneracy theory was the medical counterpart to Lamarckian biology. It explained how physical and mental disorders could result over several generations from accommodation to a pathogenic environment, such as the industrial region around Rouen, where Morel practiced as an alienist.”(Ian Dowbiggin, 1991)
This Lamarckian foundation had important practical support. C. E. Brown-Séquard’s experiments between 1843 and 1870 on guinea pigs appeared to demonstrate that deliberately injuring the nervous system could produce hereditary epilepsy in offspring — findings that French alienists cited extensively as experimental support for the inheritance of acquired pathological characteristics.(Ian Dowbiggin, 1991) The experimental psychologist Théodule Ribot lent further scientific authority in 1873 by declaring that “heredity is but one form of that ultimate law which by physicists is called the conservation of energy and by metaphysicians universal causality” — a formulation that made hereditarianism appear consistent with the laws of physics.(Ian Dowbiggin, 1991)
Emile Renaudin articulated the Lamarckian logic explicitly in 1856, arguing that heredity “accumulated” the acquired pathological characteristics of each generation, with alcoholism — spreading in epidemic proportions during the Second Empire — as the chief example of an acquired characteristic contributing to the growing wave of hereditary disease.(Ian Dowbiggin, 1991)
Spread: Magnan, Charcot, and International Dissemination
Within France, the most prominent clinical practitioner of degeneracy theory after Morel was Valentin Magnan (1835–1916) at the Sainte-Anne asylum in Paris, who had been extending Morel’s theory there since the 1860s and became the foremost hereditarian psychiatrist of the late nineteenth century.(Ian Dowbiggin, 1991) Magnan extended and, crucially, secularized the theory: he stripped Morel’s theological framing and relocated the degenerative process “firmly within brain pathology, thereby making it compatible with the materialist science of late-nineteenth-century France.”(German E. Berrios & Roy Porter (eds.), 1995) This secularization made the theory accessible to the republican alienists who dominated French psychiatry after 1870, who could not easily deploy a theory grounded in Catholic providentialism.
The neurologist Jean-Martin Charcot and his school at the Salpêtrière extended degeneracy thinking into the field of nervous disease. When Léon Gambetta appointed Charcot in 1882 to the first chair in the diseases of the nervous system at the Paris Faculty of Medicine, Charcot was already arguing that neuropathic hereditary taint was extremely important in hysteria.(Ian Dowbiggin, 1991) Jules Déjerine, a member of the Charcot school, wrote in 1886 that all illnesses of the nervous system shared a common origin in the hereditary transmission of a flawed nervous condition, dividing them between disorders without anatomical lesions (hysteria, neurasthenia, epilepsy) and those with lesions (general paralysis, locomotor ataxia).(Ian Dowbiggin, 1991) Charles Féré developed the concept of the “neuropathic family” in 1884, combining mental and neurological diseases under a single hereditary category that linked insanity to tuberculosis and general paresis.(Ian Dowbiggin, 1991)
The theory spread rapidly across national boundaries. In Britain, Henry Maudsley — the most influential British psychiatrist of the late nineteenth century — was deeply influenced by hereditarianism. In Italy, Cesare Lombroso constructed his criminal anthropology on explicitly degenerationist foundations, arguing that the “born criminal” was a biological degenerate showing atavistic reversion to earlier stages of human evolution. In Germany, the theory shaped Kraepelin’s fundamental distinction between dementia praecox — defined precisely as a degenerative, irreversible condition — and manic-depressive illness. Berrios and Hauser record that Kraepelin introduced the concept of “degenerating psychological processes” in the fourth edition of his Lehrbuch (1893), defining them as characterized by “the rapid development of a lasting state of psychological weakness.”(German E. Berrios & Roy Porter (eds.), 1995)
Degeneracy theory also percolated into mass culture. Scull notes that Émile Zola’s twenty-novel Rougon-Macquart cycle, tracing hereditary madness, alcoholism, violence, and sexual depravity across generations of a single family, was perhaps the most influential popularization of the theory for general audiences.(Andrew Scull, 2015)
The Social and Political Charge
Degeneracy theory was not a neutral scientific doctrine. It carried explicit political valence, particularly in the aftermath of the Franco-Prussian War of 1870–71 and the Paris Commune. Dowbiggin shows that alienists like Moreau de Tours and J. V. Laborde wrote political commentaries applying morbid heredity directly to the Communards, depicting the insurrection as a symptom of hereditary degeneracy — the biological expression of accumulated social pathology.(Ian Dowbiggin, 1991) The Commune became a lightning rod for hereditarian political commentary, transforming the theory from a medical argument about family lineages into a broad ideological instrument for diagnosing social unrest.
Dowbiggin argues that in the context of the Third Republic, “psychiatric hereditarianism and degeneracy theory imposed an ideologically acceptable logic on madness and other pressing social problems. By adopting hereditarianism alienists could depict the psychiatrist as a scientist endowed with moral authority and committed to naturalism, secularism, the defense of the family and private property, and the progress of civilization.”(Ian Dowbiggin, 1991)
The social consequences of the theory extended well beyond France. Shorter documents that after the 1860s, “the doctrine of degeneration meant that it was not merely the asylum that threatened the family and its honor but the psychiatrist and his menacing diagnoses. After the 1860s, the profession’s conventional terms for psychiatric illness began to ring with awfulness. The notion that major psychiatric disorders came from poisoned heredity instilled in the public a kind of permanent dread.”(Shorter, 1997) The stakes of a psychiatric diagnosis were no longer merely personal; they were dynastic. If mental illness indicated hereditary taint, then a diagnosis in one family member cast a shadow over all potential marriages, all future children, all siblings and cousins who might carry the same taint without yet manifesting it. Wealthy families sought private “nervous clinics” precisely to avoid the stigma of the hereditary label; patients admitted for “nervous exhaustion” rather than hereditary insanity preserved the family’s social position in a way that public asylum admission did not.(Shorter, 1997)
By 1900, the therapeutic optimism with which the nineteenth century had opened had almost entirely collapsed.(Porter, 1997) Asylums filled with incurable patients, and psychiatry turned toward policing the sane-insane boundary.(Porter, 1997) A German asylum physician captured the mood in 1910: “We know a lot and can do little.”(Porter, 1997)
Shorter documents that turn-of-the-century Germany had its own anti-psychiatry movement, organized under the banner of “Reform of Psychiatric Law and Psychiatric Treatment” by 1909.(Shorter, 1997) The movement’s stated aims were explicit: “We want to damn secretiveness, deception, and hypocrisy as unworthy of humankind.”(Shorter, 1997) Shorter attributes much of its energy to sensationalist press stories of wrongful confinement.(Shorter, 1997)
Langdon Down’s 1866 paper proposing ethnic classification of idiocy — including “Mongolian idiocy” as a form of racial reversion to an earlier stage of human evolution — illustrates how degeneracy theory encoded the Victorian racial hierarchy directly into clinical nosology, presenting intellectual disability as racial atavism.(German E. Berrios & Roy Porter (eds.), 1995) In the United States, Haller documents that the monogenist version of degeneracy theory — traceable to Blumenbach — offered a different route to the same racist conclusions as polygenism, arguing that races could degenerate from a common human original rather than being separately created.(Haller, 1971)
Relationship to Eugenics
The step from degeneracy theory to eugenics was short. If mental illness, criminality, and social incompetence were heritable biological conditions that worsened across generations until the affected lineage became sterile, the obvious public health intervention was to hasten that sterility artificially rather than waiting for it to occur naturally. Kevles documents that the Boer War recruitment crisis — in which eight of eleven volunteers in Manchester were rejected as physically unfit — galvanized British anxiety about “national deterioration,” leading Parliament to establish a commission on the problem in 1903.(Kevles, Daniel J., 1995) The eugenics movements in Britain, the United States, and Germany drew directly on degeneracy theory’s vocabulary and causal logic.
The legislative pathway from degeneracy theory to compulsory eugenics programs was shorter than is often assumed, and the mechanisms were specific. In the United States, marriage restriction came first. By 1914, some thirty states had enacted new marriage laws prohibiting union among those classified as eugenically unfit; Connecticut’s 1896 statute — the earliest — prohibited marriage and extramarital relations between identified degenerates, with three years’ imprisonment as the penalty.(Kevles, Daniel J., 1995) Sterilization followed within a decade. Indiana passed the first state sterilization law in 1907, driven by Dr. Harry Sharp’s program at the State Reformatory; by 1917, sixteen additional states had enacted statutes covering habitual criminals, epileptics, the insane, and those classified as “idiots” held in state institutions.(Kevles, Daniel J., 1995)
The constitutionality of these measures was settled — or rather, rubber-stamped — by the Supreme Court in 1927. In Buck v. Bell, Justice Oliver Wendell Holmes wrote for an 8-1 majority: “It is better for all the world, if instead of waiting to execute degenerate offspring for crime, or to let them starve for their imbecility, society can prevent those who are manifestly unfit from continuing their kind… Three generations of imbeciles are enough.”(Andrew Scull, 2015) By 1940, forty American states had compulsory sterilization statutes on their books.
Immigration restriction represented a third legislative instrument. The 1924 Immigration Act, signed by President Coolidge — who had publicly declared that “biological laws show that Nordics deteriorate when mixed with other races” — used 1890 census data to discriminate against Eastern and Southern European immigrants. Eugenicists celebrated it as biologically principled policy.(Kevles, Daniel J., 1995) In Britain the parallel was the Mental Deficiency Act of 1913, which granted compulsory powers to detain the “feebleminded,” including women on poor relief pregnant with illegitimate children; the Eugenics Review celebrated it as the only English social law in which heredity had been treated as a practical factor in drafting legislation.(Kevles, Daniel J., 1995)
The endpoint of degenerationist logic applied to the institutionalized mentally ill came in Nazi Germany. The 1933 Eugenic Sterilization Law led to approximately 225,000 sterilizations within three years — roughly ten times the American total accumulated over thirty years.(Kevles, Daniel J., 1995) By 1939, the regime moved beyond sterilization to the T-4 euthanasia programme, in which leading psychiatrists actively participated in the extermination of over 70,000 asylum patients within eighteen months.(Andrew Scull, 2015) The logic of the program extended beyond the diagnostically insane: Kevles records that the 1939 euthanasia orders explicitly designated all Jews in German asylums for death regardless of the state of their mental health, merging the eugenic and the antisemitic programs into a single administrative category of lives to be eliminated. Some 70,000 patients were eventually designated under this policy.(Kevles, Daniel J., 1995)
Decline: Mendelian Genetics and the Internal Contradictions
Degeneracy theory began to unravel in the early twentieth century from multiple directions. The most fundamental challenge came from Mendelian genetics, but the collapse had two distinct components: the theoretical undermining of the Lamarckian inheritance mechanism, and the empirical dissolution of the racial and behavioral claims the theory had licensed.
World War I provided a challenge to degeneration theory. Soldiers who were mute, paralyzed, trembling, or blinded without physical injury presented a clinical category that degeneracy theory could not accommodate on its own terms (Andrew Scull, 2015). Scull observes that “the initial disposition of many psychiatrists was to blame their traditional foe, degeneration” (Andrew Scull, 2015). However, applying a degenerationist label to soldiers who had fought for their country was problematic, especially as shell shock affected officers and decorated veterans as well as ordinary soldiers (Andrew Scull, 2015). The mass prevalence of shell shock among demonstrably non-degenerate men required an explanation that hereditary biological inferiority could not supply (Andrew Scull, 2015).
The second challenge came from Freudian psychoanalysis. Scull argues that where Kraepelin had “erected a seemingly impenetrable barrier between the biologically degenerate and physically inferior specimens who swarmed the back wards of lunatic asylums, and the majority of sane citizens,” Freud denied that madness was the problem of the Other alone. In Freud’s account, the unconscious harbored conflict in everyone: “civilization and its discontents,” Freud argued, were locked in an “indissoluble embrace.”(Andrew Scull, 2015) This move dissolved the boundary that degeneracy theory had drawn between the hereditarily tainted minority and the normal majority, replacing it with a universal psychology of conflict and repression that made psychiatric illness a matter of degree, not of biological kind.
Gregor Mendel’s 1865 paper on hereditary elements in peas had gone unrecognized for thirty-five years because biologists of the Darwinian era were focused on the adaptation of species — on change — while Mendel’s theory accounted for the ongoing transmission of characters, for stability.(Kevles, Daniel J., 1995) The simultaneous rediscovery in 1900 by Carl Correns, Erich Tschermak, and Hugo de Vries opened a new era in which heredity became particulate, discrete, and subject to experimental analysis.(Kevles, Daniel J., 1995) Thomas Hunt Morgan’s Drosophila research team at Columbia then identified the chromosome as the physical seat of the gene, providing a mechanistic account of hereditary transmission that could not accommodate degenerationism’s blending, cumulative model.(Kevles, Daniel J., 1995)
Mendelian genetics was incompatible with the theory’s two load-bearing assumptions. First, Mendelian inheritance was discrete, not blending: a hereditary character did not accumulate environmental damage and transmit the sum to offspring; it was either present or absent according to dominant-recessive rules. Second, August Weismann’s germ-plasm theory — which had bolstered pre-Mendelian hereditarianism by asserting that the hereditary substance was impermeable to environmental influence — was confirmed rather than challenged by the new genetics, but in a way that actually undermined Lamarckian degeneration: if heredity resided in germ plasm impervious to environmental modification, then the whole mechanism by which acquired damage was supposed to accumulate across generations was biologically incoherent.(Kevles, Daniel J., 1995)
The second direction of challenge was empirical. Geneticists who took the new science seriously recognized that its tools provided no basis for the broad racial and behavioral claims degeneracy theory had licensed. Thomas Hunt Morgan, who knew Mendelian genetics from the inside, declared in 1925 that there existed no scientific assurance for “deciding genetic superiority or inferiority as applied to whole races” — which were, he argued, social and political groupings, not biological ones.(Kevles, Daniel J., 1995) Crime statistics, meanwhile, had moved in precisely the opposite direction from what the theory predicted: the British crime rate per hundred thousand had actually fallen forty percent in the fifty years before 1911.(Kevles, Daniel J., 1995) The same empirical discipline that had seemed to legitimate eugenics at its origin was, as it matured, dissolving the degenerationist framework from within.
There were also internal logical problems. Berrios and Beer note that Morel’s degeneracy theory seemed to entail a contradiction: it proposed a longitudinal, trans-generational “invariant” that produced different clinical pictures in each generation, but Morel never explained why the same metamorphosis did not also occur within a single individual’s lifetime — as Griesinger’s cascade model had implied. Furthermore, Morel’s own 1860 taxonomic classification of mental illness cross-sectionally seemed inconsistent with the longitudinal hereditary model.(German E. Berrios & Roy Porter (eds.), 1995)
Georges Génil-Perrin’s 1913 historical study of the degeneracy concept effectively marked its clinical end. He concluded that degeneracy “explained everything and nothing” and had been reduced to a simple sign of organic inferiority — a label attached to any patient the psychiatrist could not otherwise categorize.(Ian Dowbiggin, 1991) By this point, Freudian psychoanalysis was offering an alternative account of mental illness grounded in individual psychology rather than hereditary biology, and Bleuler’s 1911 reconceptualization of dementia praecox as “schizophrenia” had removed the deterministic prognosis — the irreversible degenerative trajectory — that was central to the Kraepelinian/Morelian model.(German E. Berrios & Roy Porter (eds.), 1995)
Legacy
The legacy of degeneracy theory runs through psychiatric classification, stigma, and political ideology. Its influence on the structure of Kraepelin’s nosology — particularly the distinction between irreversible deteriorating psychoses and more hopeful conditions — left traces that persisted into the DSM era. The theory created what Shorter calls a “permanent dread” around psychiatric diagnosis that shaped patient behavior well into the twentieth century, driving the elaborate avoidance strategies (the flight into “nervous” diagnosis, the preference for private clinics over public asylums) that characterized middle-class responses to mental illness.
More broadly, degeneracy theory established a template for linking psychiatric diagnosis to social hierarchy and political order. The asylum psychiatrist who wielded the concept of hereditary degeneracy was simultaneously a medical scientist, a social hygienist, and a servant of the state — a combination of roles that made the profession politically powerful but also made it complicit in programs of exclusion and, eventually, extermination. Dowbiggin’s study of French psychiatry makes clear that this was not an accident or a perversion of the theory: the ideological utility of degeneracy for defending professional privilege and endorsing political order was built into the theory from its origins in the crisis of French alienism under Napoleon III.
