Free thought

From Wikipedia, the free encyclopedia
https://en.wikipedia.org/wiki/Free_thought

Free thought (sometimes spelled freethought) is an epistemological viewpoint which holds that beliefs should not be formed on the basis of authority, tradition, revelation, or dogma, and that beliefs should instead be reached by other methods such as logic, reason, and empirical observation. According to the Oxford English Dictionary, a freethinker is "a person who forms their own ideas and opinions rather than accepting those of other people, especially in religious teaching." In some contemporary thought in particular, free thought is strongly tied with rejection of traditional social or religious belief systems. The cognitive application of free thought is known as "freethinking", and practitioners of free thought are known as "freethinkers". Modern freethinkers consider free thought to be a natural freedom from all negative and illusive thoughts acquired from the society.

The term first came into use in the 17th century in order to refer to people who inquired into the basis of traditional beliefs which were often accepted unquestioningly. Today, freethinking is most closely linked with secularism, atheism, agnosticism, humanism, anti-clericalism, and religious critique. The Oxford English Dictionary defines freethinking as, "The free exercise of reason in matters of religious belief, unrestrained by deference to authority; the adoption of the principles of a free-thinker." Freethinkers hold that knowledge should be grounded in facts, scientific inquiry, and logic. The skeptical application of science implies freedom from the intellectually limiting effects of confirmation bias, cognitive bias, conventional wisdom, popular culture, urban myth, prejudice, or sectarianism.

Definition

Atheist author Adam Lee defines free thought as thinking which is independent of revelation, tradition, established belief, and authority, and considers it as a "broader umbrella" than atheism "that embraces a rainbow of unorthodoxy, religious dissent, skepticism, and unconventional thinking."

The basic summarizing statement of the essay The Ethics of Belief by the 19th-century British mathematician and philosopher William Kingdon Clifford is: "It is wrong always, everywhere, and for anyone, to believe anything upon insufficient evidence." The essay became a rallying cry for freethinkers when published in the 1870s, and has been described as a point when freethinkers grabbed the moral high ground. Clifford was himself an organizer of free thought gatherings, the driving force behind the Congress of Liberal Thinkers held in 1878.

Regarding religion, freethinkers typically hold that there is insufficient evidence to support the existence of supernatural phenomena. According to the Freedom from Religion Foundation, "No one can be a freethinker who demands conformity to a bible, creed, or messiah. To the freethinker, revelation and faith are invalid, and orthodoxy is no guarantee of truth." and "Freethinkers are convinced that religious claims have not withstood the tests of reason. Not only is there nothing to be gained by believing an untruth, but there is everything to lose when we sacrifice the indispensable tool of reason on the altar of superstition. Most freethinkers consider religion to be not only untrue, but harmful."

However, philosopher Bertrand Russell wrote the following in his 1944 essay "The Value of Free Thought:"

What makes a freethinker is not his beliefs but the way in which he holds them. If he holds them because his elders told him they were true when he was young, or if he holds them because if he did not he would be unhappy, his thought is not free; but if he holds them because, after careful thought he finds a balance of evidence in their favour, then his thought is free, however odd his conclusions may seem.

— Bertrand Russell, The Value of Free Thought. How to Become a Truth-Seeker and Break the Chains of Mental Slavery, from the first paragraph

The whole first paragraph of the essay makes it clear that a freethinker is not necessarily an atheist or an agnostic, as long as he or she satisfies this definition:

The person who is free in any respect is free from something; what is the free thinker free from? To be worthy of the name, he must be free of two things: the force of tradition, and the tyranny of his own passions. No one is completely free from either, but in the measure of a man's emancipation he deserves to be called a free thinker.

— Bertrand Russell, The Value of Free Thought. How to Become a Truth-Seeker and Break the Chains of Mental Slavery, from the first paragraph

Fred Edwords, former executive of the American Humanist Association, suggests that by Russell's definition, liberal religionists who have challenged established orthodoxies can be considered freethinkers.

On the other hand, according to Bertrand Russell, atheists and/or agnostics are not necessarily freethinkers. As an example, he mentions Stalin, whom he compares to a "pope":

what I am concerned with is the doctrine of the modern Communistic Party, and of the Russian Government to which it owes allegiance. According to this doctrine, the world develops on the lines of a Plan called Dialectical Materialism, first discovered by Karl Marx, embodied in the practice of a great state by Lenin, and now expounded from day to day by a Church of which Stalin is the Pope. […] Free discussion is to be prevented wherever the power to do so exists; […] If this doctrine and this organization prevail, free inquiry will become as impossible as it was in the middle ages, and the world will relapse into bigotry and obscurantism.

— Bertrand Russell, The Value of Free Thought. How to Become a Truth-Seeker and Break the Chains of Mental Slavery

In the 18th and 19th century, many thinkers regarded as freethinkers were deists, arguing that the nature of God can only be known from a study of nature rather than from religious revelation. In the 18th century, "deism" was as much of a 'dirty word' as "atheism", and deists were often stigmatized as either atheists or at least as freethinkers by their Christian opponents. Deists today regard themselves as freethinkers, but are now arguably less prominent in the free thought movement than atheists.

Characteristics

Among freethinkers, for a notion to be considered true it must be testable, verifiable, and logical. Many freethinkers tend to be humanists, who base morality on human needs and would find meaning in human compassion, social progress, art, personal happiness, love, and the furtherance of knowledge. Generally, freethinkers like to think for themselves, tend to be skeptical, respect critical thinking and reason, remain open to new concepts, and are sometimes proud of their own individuality. They would determine truth for themselves – based upon knowledge they gain, answers they receive, experiences they have and the balance they thus acquire. Freethinkers reject conformity for the sake of conformity, whereby they create their own beliefs by considering the way the world around them works and would possess the intellectual integrity and courage to think outside of accepted norms, which may or may not lead them to believe in some higher power.

Symbol

The pansy, a symbol of freethought.

The pansy serves as the long-established and enduring symbol of free thought; literature of the American Secular Union inaugurated its usage in the late 1800s. The reasoning behind the pansy as the symbol of free thought lies both in the flower's name and in its appearance. The pansy derives its name from the French word pensée, which means "thought". It allegedly received this name because the flower is perceived by some to bear resemblance to a human face, and in mid-to-late summer it nods forward as if deep in thought. Challenging Religious Dogma: A History of Free Thought, a pamphlet dating from the 1880s had this statement under the title "The Pansy Badge":

There is . . . need of a badge which shall express at first glance, without complexity of detail, that basic principle of freedom of thought for which Liberals of all isms are contending. This need seems to have been met by the Freethinkers of France, Belgium, Spain and Sweden, who have adopted the pansy as their badge. We join with them in recommending this flower as a simple and inexpensive badge of Freethought...Let every patriot who is a Freethinker in this sense, adopt the pansy as his badge, to be worn at all times, as a silent and unobtrusive testimony of his principles. In this way we shall recognize our brethren in the cause, and the enthusiasm will spread; until, before long, the uplifted standard of the pansy, beneath the sheltering folds of the United States flag, shall everywhere thrill men's hearts as the symbol of religious liberty and freedom of conscience."

History

Pre-modern movement

Critical thought has flourished in the Hellenistic Mediterranean, in the repositories of knowledge and wisdom in Ireland and in the Iranian civilizations (for example in the era of Khayyam (1048–1131) and his unorthodox Sufi Rubaiyat poems), and in other civilizations, such as the Chinese (note for example the seafaring renaissance of the Southern Song dynasty of 420–479), and on through heretical thinkers on esoteric alchemy or astrology, to the Renaissance and the Protestant Reformation.

French physician and writer Rabelais celebrated "rabelaisian" freedom as well as good feasting and drinking (an expression and a symbol of freedom of the mind) in defiance of the hypocrisies of conformist orthodoxy in his utopian Thelema Abbey (from θέλημα: free "will"), the device of which was Do What Thou Wilt:

So had Gargantua established it. In all their rule and strictest tie of their order there was but this one clause to be observed, Do What Thou Wilt; because free people ... act virtuously and avoid vice. They call this honor.

When Rabelais's hero Pantagruel journeys to the "Oracle of The Div(in)e Bottle", he learns the lesson of life in one simple word: "Trinch!", Drink! Enjoy the simple life, learn wisdom and knowledge, as a free human. Beyond puns, irony, and satire, Gargantua's prologue-metaphor instructs the reader to "break the bone and suck out the substance-full marrow" ("la substantifique moëlle"), the core of wisdom.

Modern movements

The year 1600 is considered a landmark in the era of modern free thought. It was the year of the execution in Italy of Giordano Bruno, a former Dominican friar, by the Inquisition.

England

The term freethinker emerged towards the end of the 17th century in England to describe those who stood in opposition to the institution of the Church, and the literal belief in the Bible. The beliefs of these individuals were centered on the concept that people could understand the world through consideration of nature. Such positions were formally documented for the first time in 1697 by William Molyneux in a widely publicized letter to John Locke, and more extensively in 1713, when Anthony Collins wrote his Discourse of Free-thinking, which gained substantial popularity. This essay attacks the clergy of all churches and it is a plea for deism.

The Freethinker magazine was first published in Britain in 1881.

France

In France, the concept first appeared in publication in 1765 when Denis Diderot, Jean le Rond d'Alembert, and Voltaire included an article on Liberté de penser in their Encyclopédie. The concept of free thought spread so widely that even places as remote as the Jotunheimen, in Norway, had well-known freethinkers such as Jo Gjende by the 19th century.

François-Jean Lefebvre de la Barre (1745–1766) was a young French nobleman, famous for having been tortured and beheaded before his body was burnt on a pyre along with Voltaire's Philosophical Dictionary. La Barre is often said to have been executed for not saluting a Roman Catholic religious procession, but the elements of the case were far more complex.

In France, Lefebvre de la Barre is widely regarded a symbol of the victims of Christian religious intolerance; La Barre along with Jean Calas and Pierre-Paul Sirven, was championed by Voltaire. A second replacement statue to de la Barre stands nearby the Basilica of the Sacred Heart of Jesus of Paris at the summit of the butte Montmartre (itself named from the Temple of Mars), the highest point in Paris and an 18th arrondissement street nearby the Sacré-Cœur is also named after Lefebvre de la Barre.

The 19th century saw the emergence of a specific notion of Libre-Pensée ("free thought"), with writer Victor Hugo as one of its major early proponents. French Freethinkers (Libre-Penseurs) associate freedom of thought, political anti-clericalism and socialist leanings. The main organisation referring to this tradition to this day is the Fédération nationale de la libre pensée, created in 1890.

Germany

In Germany, during the period 1815–1848 and before the March Revolution, the resistance of citizens against the dogma of the church increased. In 1844, under the influence of Johannes Ronge and Robert Blum, belief in the rights of man, tolerance among men, and humanism grew, and by 1859 they had established the Bund Freireligiöser Gemeinden Deutschlands (literally Union of Free Religious Communities of Germany), an association of persons who consider themselves to be religious without adhering to any established and institutionalized church or sacerdotal cult. This union still exists today, and is included as a member in the umbrella organization of free humanists. In 1881 in Frankfurt am Main, Ludwig Büchner established the Deutscher Freidenkerbund (German Freethinkers League) as the first German organization for atheists and agnostics. In 1892 the Freidenker-Gesellschaft and in 1906 the Deutscher Monistenbund were formed.

Free thought organizations developed the "Jugendweihe" (literally Youth consecration), a secular "confirmation" ceremony, and atheist funeral rites. The Union of Freethinkers for Cremation was founded in 1905, and the Central Union of German Proletariat Freethinker in 1908. The two groups merged in 1927, becoming the German Freethinking Association in 1930.

More "bourgeois" organizations declined after World War I, and "proletarian" free thought groups proliferated, becoming an organization of socialist parties. European socialist free thought groups formed the International of Proletarian Freethinkers (IPF) in 1925. Activists agitated for Germans to disaffiliate from their respective Church and for seculari-zation of elementary schools; between 1919–21 and 1930–32 more than 2.5 million Germans, for the most part supporters of the Social Democratic and Communist parties, gave up church membership. Conflict developed between radical forces including the Soviet League of the Militant Godless and Social Democratic forces in Western Europe led by Theodor Hartwig and Max Sievers. In 1930 the Soviet and allied delegations, following a walk-out, took over the IPF and excluded the former leaders. Following Hitler's rise to power in 1933, most free thought organizations were banned, though some right-wing groups that worked with so-called Völkische Bünde (literally "ethnic" associations with nationalist, xenophobic and very often racist ideology) were tolerated by the Nazis until the mid-1930s.

Belgium

The Université Libre de Bruxelles and the Vrije Universiteit Brussel, along with the two Circles of Free Inquiry (Dutch and French speaking), defend the freedom of critical thought, lay philosophy and ethics, while rejecting the argument of authority.

Netherlands

In the Netherlands, free thought has existed in organized form since the establishment of De Dageraad (now known as De Vrije Gedachte) in 1856. Among its most notable subscribing 19th century individuals were Johannes van Vloten, Multatuli, Adriaan Gerhard and Domela Nieuwenhuis.

In 2009, Frans van Dongen established the Atheist-Secular Party, which takes a considerably restrictive view of religion and public religious expressions.

Since the 19th century, free thought in the Netherlands has become more well known as a political phenomenon through at least three currents: liberal freethinking, conservative freethinking, and classical freethinking. In other words, parties which identify as freethinking tend to favor non-doctrinal, rational approaches to their preferred ideologies, and arose as secular alternatives to both clerically aligned parties as well as labor-aligned parties. Common themes among freethinking political parties are "freedom", "liberty", and "individualism".

Switzerland

With the introduction of cantonal church taxes in the 1870s, anti-clericals began to organise themselves. Around 1870, a "freethinkers club" was founded in Zürich. During the debate on the Zürich church law in 1883, professor Friedrich Salomon Vögelin and city council member Kunz proposed to separate church and state.

Turkey

In the last years of the Ottoman Empire, free thought made its voice heard by the works of distinguished people such as Ahmet Rıza, Tevfik Fikret, Abdullah Cevdet, Kılıçzade Hakkı, and Celal Nuri İleri. These intellectuals affected the early period of the Turkish Republic. Mustafa Kemal Atatürkfield marshal, revolutionary statesman, author, and founder of the secular Turkish nation state, serving as its first President from 1923 until his death in 1938– was the practitioner of their ideas. He made many reforms that modernized the country. Sources point out that Atatürk was a religious skeptic and a freethinker. He was a non-doctrinaire deist or an atheist, who was antireligious and anti-Islamic in general. According to Atatürk, the Turkish people do not know what Islam really is and do not read the Quran. People are influenced by Arabic sentences that they do not understand, and because of their customs they go to mosques. When the Turks read the Quran and think about it, they will leave Islam. Atatürk described Islam as the religion of the Arabs in his own work titled Vatandaş için Medeni Bilgiler by his own critical and nationalist views.

Association of Atheism (Ateizm Derneği), the first official atheist organisation in Middle East and Caucasus, was founded in 2014. It serves to support irreligious people and freethinkers in Turkey who are discriminated against based on their views. In 2018 it was reported in some media outlets that the Ateizm Derneği would close down because of the pressure on its members and attacks by pro-government media, but the association itself issued a clarification that this was not the case and that it was still active.

United States

The Free Thought movement first organized itself in the United States as the "Free Press Association" in 1827 in defense of George Houston, publisher of The Correspondent, an early journal of Biblical criticism in an era when blasphemy convictions were still possible. Houston had helped found an Owenite community at Haverstraw, New York in 1826–27. The short-lived Correspondent was superseded by the Free Enquirer, the official organ of Robert Owen's New Harmony community in Indiana, edited by Robert Dale Owen and by Fanny Wright between 1828 and 1832 in New York. During this time Robert Dale Owen sought to introduce the philosophic skepticism of the Free Thought movement into the Workingmen's Party in New York City. The Free Enquirer's annual civic celebrations of Paine's birthday after 1825 finally coalesced in 1836 in the first national Free Thinkers organization, the "United States Moral and Philosophical Society for the General Diffusion of Useful Knowledge". It was founded on August 1, 1836, at a national convention at the Lyceum in Saratoga Springs with Isaac S. Smith of Buffalo, New York, as president. Smith was also the 1836 Equal Rights Party's candidate for Governor of New York and had also been the Workingmen's Party candidate for Lt. Governor of New York in 1830. The Moral and Philosophical Society published The Beacon, edited by Gilbert Vale.

Driven by the revolutions of 1848 in the German states, the 19th century saw an immigration of German freethinkers and anti-clericalists to the United States (see Forty-Eighters). In the United States, they hoped to be able to live by their principles, without interference from government and church authorities.

Many Freethinkers settled in German immigrant strongholds, including St. Louis, Indianapolis, Wisconsin, and Texas, where they founded the town of Comfort, Texas, as well as others.

These groups of German Freethinkers referred to their organizations as Freie Gemeinden, or "free congregations". The first Freie Gemeinde was established in St. Louis in 1850. Others followed in Pennsylvania, California, Washington, D.C., New York, Illinois, Wisconsin, Texas, and other states.

Freethinkers tended to be liberal, espousing ideals such as racial, social, and sexual equality, and the abolition of slavery.

The "Golden Age of Freethought" in the US came in the late 1800s. The dominant organization was the National Liberal League which formed in 1876 in Philadelphia. This group re-formed itself in 1885 as the American Secular Union under the leadership of the eminent agnostic orator Robert G. Ingersoll. Following Ingersoll's death in 1899 the organization declined, in part due to lack of effective leadership.

Free thought in the United States declined in the early twentieth century. By the early twentieth century, most free thought congregations had disbanded or joined other mainstream churches. The longest continuously operating free thought congregation in America is the Free Congregation of Sauk County, Wisconsin, which was founded in 1852 and is still active as of 2020. It affiliated with the American Unitarian Association (now the Unitarian Universalist Association) in 1955. D. M. Bennett was the founder and publisher of The Truth Seeker in 1873, a radical free thought and reform American periodical.

German Freethinker settlements were located in:

Canada

In 1873 a handful of secularists founded the earliest known secular organization in English Canada, the Toronto Freethought Association. Reorganized in 1877 and again in 1881, when it was renamed the Toronto Secular Society, the group formed the nucleus of the Canadian Secular Union, established in 1884 to bring together freethinkers from across the country.

A significant number of the early members appear to have come from the educated labour "aristocracy", including Alfred F. Jury, J. Ick Evans and J. I. Livingstone, all of whom were leading labour activists and secularists. The second president of the Toronto association, T. Phillips Thompson, became a central figure in the city's labour and social-reform movements during the 1880s and 1890s and arguably Canada's foremost late nineteenth-century labour intellectual. By the early 1880s scattered free thought organizations operated throughout southern Ontario and parts of Quebec, eliciting both urban and rural support.

The principal organ of the free thought movement in Canada was Secular Thought (Toronto, 1887–1911). Founded and edited during its first several years by English freethinker Charles Watts (1835–1906), it came under the editorship of Toronto printer and publisher James Spencer Ellis in 1891 when Watts returned to England. In 1968 the Humanist Association of Canada (HAC) formed to serve as an umbrella group for humanists, atheists, and freethinkers, and to champion social justice issues and oppose religious influence on public policy—most notably in the fight to make access to abortion free and legal in Canada.

Anarchism

In the United States of America,

"free thought was a basically anti-Christian, anti-clerical movement, whose purpose was to make the individual politically and spiritually free to decide for himself on religious matters. A number of contributors to Liberty were prominent figures in both free thought and anarchism. The individualist anarchist George MacDonald was a co-editor of Freethought and, for a time, The Truth Seeker. E.C. Walker was co-editor of the freethought/free love journal Lucifer, the Light-Bearer."

"Many of the anarchists were ardent freethinkers; reprints from free thought papers such as Lucifer, the Light-Bearer, Freethought and The Truth Seeker appeared in Liberty...The church was viewed as a common ally of the state and as a repressive force in and of itself." In Europe, a similar development occurred in French and Spanish individualist anarchist circles:

"Anticlericalism, just as in the rest of the libertarian movement, in another of the frequent elements which will gain relevance related to the measure in which the (French) Republic begins to have conflicts with the church...Anti-clerical discourse, frequently called for by the French individualist André Lorulot, will have its impacts in Estudios (a Spanish individualist anarchist publication). There will be an attack on institutionalized religion for the responsibility that it had in the past on negative developments, for its irrationality which makes it a counterpoint of philosophical and scientific progress. There will be a criticism of proselytism and ideological manipulation which happens on both believers and agnostics".

These tendencies would continue in French individualist anarchism in the work and activism of Charles-Auguste Bontemps (1893-1981) and others. In the Spanish individualist anarchist magazines Ética and Iniciales

"there is a strong interest in publishing scientific news, usually linked to a certain atheist and anti-theist obsession, philosophy which will also work for pointing out the incompatibility between science and religion, faith, and reason. In this way there will be a lot of talk on Darwin's theories or on the negation of the existence of the soul".

In 1901 the Catalan anarchist and freethinker Francesc Ferrer i Guàrdia established "modern" or progressive schools in Barcelona in defiance of an educational system controlled by the Catholic Church. The schools had the stated goal to "educate the working class in a rational, secular and non-coercive setting". Fiercely anti-clerical, Ferrer believed in "freedom in education", education free from the authority of church and state. Ferrer's ideas, generally, formed the inspiration for a series of Modern Schools in the United States, Cuba, South America and London. The first of these started in New York City in 1911. Ferrer also inspired the Italian newspaper Università popolare, founded in 1901.

Mass psychogenic illness

Mass psychogenic illness (MPI), also called mass sociogenic illness, mass psychogenic disorder, epidemic hysteria, or mass hysteria, is "the rapid spread of illness signs and symptoms affecting members of a cohesive group, originating from a nervous system disturbance involving excitation, loss, or alteration of function, whereby physical complaints that are exhibited unconsciously have no corresponding organic aetiology".

Etiology

Mass psychogenic illness involves the spread of illness symptoms through a population where there is no viral or bacterial agent responsible for contagion. MPI is distinct from other types of collective delusions by involving physical symptoms. According to Balaratnasingam and Janca, "Mass hysteria is to date a poorly understood condition. Little certainty exists regarding its etiology". Qualities of MPI outbreaks often include:

  • symptoms that have no plausible organic basis;
  • symptoms that are transient and benign;
  • symptoms with rapid onset and recovery;
  • occurrence in a segregated group;
  • the presence of extraordinary anxiety;
  • symptoms that are spread via sight, sound or oral communication;
  • a spread that moves down the age scale, beginning with older or higher-status people;
  • a preponderance of female participants.

British psychiatrist Simon Wesseley distinguishes between two forms of MPI:

  • Mass anxiety hysteria "consists of episodes of acute anxiety, occurring mainly in schoolchildren. Prior tension is absent and the rapid spread is by visual contact."
  • Mass motor hysteria "consists of abnormalities in motor behaviour. It occurs in any age group and prior tension is present. Initial cases can be identified and the spread is gradual. . . . [T]he outbreak may be prolonged."

While his definition is sometimes adhered to, others such as Ali-Gombe et al. of the University of Maiduguri, Nigeria contest Wesseley's definition and describe outbreaks with qualities of both mass motor hysteria and mass anxiety hysteria.

The DSM-IV-TR does not have specific diagnosis for this condition but the text describing conversion disorder states that "In 'epidemic hysteria', shared symptoms develop in a circumscribed group of people following 'exposure' to a common precipitant."

Common symptoms

Timothy F. Jones of the Tennessee Department of Health compiles the following symptoms based on their commonality in outbreaks occurring in 1980–1990:

Symptom Percent reporting
Headache 67
Dizziness or light-headedness 46
Nausea 41
Abdominal cramps or pain 39
Cough 31
Fatigue, drowsiness or weakness 31
Sore or burning throat 30
Hyperventilation or difficulty breathing 19
Watery or irritated eyes 13
Chest tightness/chest pain 12
Inability to concentrate/trouble thinking 11
Vomiting 10
Tingling, numbness or paralysis 10
Anxiety or nervousness 8
Diarrhea 7
Trouble with vision 7
Rash 4
Loss of consciousness/syncope 4
Itching 3

Prevalence and intensity

Adolescents and children are frequently affected in cases of MPI. The hypothesis that those prone to extroversion or neuroticism, or those with low IQ scores, are more likely to be affected in an outbreak of hysterical epidemic has not been consistently supported by research. Bartholomew and Wesseley state that it "seems clear that there is no particular predisposition to mass sociogenic illness and it is a behavioural reaction that anyone can show in the right circumstances."

Intense media coverage seems to exacerbate outbreaks. The illness may also recur after the initial outbreak. John Waller advises that once it is determined that the illness is psychogenic, it should not be given credence by authorities. For example, in the Singapore factory case study, calling in a medicine man to perform an exorcism seemed to perpetuate the outbreak.

Research

Besides the difficulties common to all research involving the social sciences, including a lack of opportunity for controlled experiments, mass sociogenic illness presents special difficulties to researchers in this field. Balaratnasingam and Janca report that the methods for "diagnosis of mass hysteria remain contentious." According to Jones, the effects resulting from MPI "can be difficult to differentiate from [those of] bioterrorism, rapidly spreading infection or acute toxic exposure."

These troubles result from the residual diagnosis of MPI. Singer, of the Uniformed Schools of Medicine, puts the problems with such a diagnosis thus: "[y]ou find a group of people getting sick, you investigate, you measure everything you can measure . . . and when you still can't find any physical reason, you say 'well, there's nothing else here, so let's call it a case of MPI.'" There is a lack of logic in an argument that proceeds: "There isn't anything, so it must be MPI." It precludes the notion that an organic factor could have been overlooked. Nevertheless, running an extensive number of tests extends the probability of false positives.

In history

Middle Ages

The earliest studied cases linked with epidemic hysteria are the dancing manias of the Middle Ages, including St. John's dance and tarantism. These were supposed to be associated with spirit possession or the bite of the tarantula. Those afflicted with dancing mania would dance in large groups, sometimes for weeks at a time. The dancing was sometimes accompanied by stripping, howling, the making of obscene gestures, or even (reportedly) laughing or crying to the point of death. Dancing mania was widespread over Europe.

Between the 15th and 19th centuries, instances of motor hysteria were common in nunneries. The young ladies that made up these convents were typically forced there by family. Once accepted, they took vows of chastity and poverty. Their lives were highly regimented and often marked by strict disciplinary action. The nuns would exhibit a variety of behaviors, usually attributed to demonic possession. They would often use crude language and exhibit suggestive behaviors. One convent's nuns would regularly meow like cats. Priests were often called in to exorcise demons.

18th to 21st centuries

In factories

MPI outbreaks occurred in factories following the industrial revolution in England, France, Germany, Italy and Russia as well as the United States and Singapore.

W. H. Phoon, Ministry of Labour in Singapore gives a case study of six outbreaks of MPI in Singapore factories between 1973 and 1978. They were characterized by (1) hysterical seizures of screaming and general violence, wherein tranquilizers were ineffective (2) trance states, where a worker would claim to be speaking under the influence of a spirit or jinn (or genie) and (3) frightened spells: some workers complained of unprecedented fear, or of being cold, numb, or dizzy. Outbreaks would subside in about a week. Often a bomoh (medicine man) would be called in to do a ritual exorcism. This technique was not effective and sometimes seemed to exacerbate the MPI outbreak. Females and Malays were affected disproportionately.

Especially notable is the "June Bug" outbreak: In June 1962, a peak month in factory production, sixty-two workers at a dressmaking factory in a textile town in the Southern United States experienced symptoms including severe nausea and breaking out on the skin. Most outbreaks occurred during the first shift, where four fifths of the workers were female. Of 62 total outbreaks, 59 were women, some of whom believed they were bitten by bugs from a fabric shipment, so entomologists and others were called in to discover the pathogen, but none was found. Kerchoff coordinated the interview of affected and unaffected workers at the factory and summarizes his findings:

  • Strain – those affected were more likely to work overtime frequently and provide the majority of the family income. Many were married with children.
  • Affected persons tended to deny their difficulties. Kerchoff postulates that such were "less likely to cope successfully under conditions of strain."
  • Results seemed consistent with a model of social contagion. Groups of affected persons tended to have strong social ties.

Kerchoff also links the rapid rate of contagion with the apparent reasonableness of the bug infestation theory and the credence given to it in accompanying news stories.

Stahl and Lebedun describe an outbreak of mass sociogenic illness in the data center of a university town in the United States mid-west in 1974. Ten of thirty-nine workers smelling an unconfirmed "mystery gas" were rushed to a hospital with symptoms of dizziness, fainting, nausea and vomiting. They report that most workers were young women either putting their husbands through school or supplementing the family income. Those affected were found to have high levels of job dissatisfaction. Those with strong social ties tended to have similar reactions to the supposed gas, which only one unaffected woman reported smelling. No gas was detected in subsequent tests of the data center.

In schools

Thousands were affected by the spread of a supposed illness in a province of Kosovo in March to June of 1990, exclusively affecting ethnic Albanians, most of whom were young adolescents. A wide variety of symptoms were manifested, including headache, dizziness, impeded respiration, weakness/adynamia, burning sensations, cramps, retrosternal/chest pain, dry mouth and nausea. After the illness had subsided, a bipartisan Federal Commission released a document, offering the explanation of psychogenic illness. Radovanovic of the Department of Community Medicine and Behavioural Sciences Faculty of Medicine in Safat, Kuwait reports:

This document did not satisfy either of the two ethnic groups. Many Albanian doctors believed that what they had witnessed was an unusual epidemic of poisoning. The majority of their Serbian colleagues also ignored any explanation in terms of psychopathology. They suggested that the incident was faked with the intention of showing Serbs in a bad light but that it failed due to poor organization.

Rodovanovic expects that this reported instance of mass sociogenic illness was precipitated by the demonstrated volatile and culturally tense situation in the province.

The Tanganyika laughter epidemic of 1962 was an outbreak of laughing attacks rumored to have occurred in or near the village of Kanshasa on the western coast of Lake Victoria in the modern nation of Tanzania, eventually affecting 14 different schools and over 1000 people.

On the morning of Thursday 7 October 1965, at a girls' school in Blackburn in England, several girls complained of dizziness. Some fainted. Within a couple of hours, 85 girls from the school were rushed by ambulance to a nearby hospital after fainting. Symptoms included swooning, moaning, chattering of teeth, hyperpnea, and tetany. Moss and McEvedy published their analysis of the event about one year later. Their conclusions follow. Note that their conclusion about the above-average extraversion and neuroticism of those affected is not necessarily typical of MPI:

  • Clinical and laboratory findings were essentially negative.
  • Investigations by the public health authorities did not uncover any evidence of pollution of food or air.
  • The epidemiology of the outbreak was investigated by means of questionnaires administered to the whole school population. It was established that the outbreaks began among the 14-year-olds, but that the heaviest incidence moved to the youngest age groups.
  • By using the Eysenck Personality Inventory, it was established that, in all age groups, the mean E [extraversion] and N [neuroticism] scores of the affected were higher than those of the unaffected.
  • The younger girls proved more susceptible, but disturbance was more severe and lasted longer in the older girls.
  • It was considered that the epidemic was hysterical, that a previous polio epidemic had rendered the population emotionally vulnerable, and that a three-hour parade, producing 20 faints on the day before the first outbreak, had been the specific trigger.
  • The data collected were thought to be incompatible with organic theories and with the compromise theory of an organic nucleus.

Another possible case occurred in Belgium in June 1999 when people, mainly schoolchildren, became ill after drinking Coca-Cola. In the end, scientists were divided over the scale of the outbreak, whether it fully explains the many different symptoms and the scale to which sociogenic illness affected those involved.

A possible outbreak of mass psychogenic illness occurred at Le Roy Junior-Senior High School in upstate New York, United States, in which multiple students began suffering symptoms similar to Tourette syndrome. Various health professionals ruled out such factors as Gardasil, drinking water contamination, illegal drugs, carbon monoxide poisoning and various other potential environmental or infectious causes, before diagnosing the students with a conversion disorder and mass psychogenic illness.

Starting around 2009, a spate of apparent poisonings at girls' schools across Afghanistan began to be reported; symptoms included dizziness, fainting and vomiting. The United Nations, World Health Organization and NATO's International Security Assistance Force carried out investigations of the incidents over multiple years, but never found any evidence of toxins or poisoning in the hundreds of blood, urine and water samples they tested. The conclusion of the investigators was that the girls were suffering from mass psychogenic illness.

In August 2019 the BBC reported that schoolgirls at the Ketereh national secondary school (SMK Ketereh) in Kelantan, Malaysia, started screaming, with some claiming to have seen 'a face of pure evil'. Dr Simon Wessely of King's College Hospital, London suggested it was a form of 'collective behaviour'. Robert Bartholomew, an American medical sociologist and author, said, "It is no coincidence that Kelantan, the most religiously conservative of all Malaysian states, is also the one most prone to outbreaks." This view is supported by Afiq Noor, an academic, who argues that the stricter implementation of Islamic law in school in states such as Kelantan is linked to the outbreaks. He suggested that the screaming outbreak was caused by the constricted environment. In Malaysian culture burial sites and trees are common settings for supernatural tales about the spirits of dead infants (toyol), vampiric ghosts (pontianak) and vengeful female spirits (penanggalan). Authorities responded to the Kelantan outbreak by cutting down trees around the school. Outbreaks of mass psychogenic illness have been reported in Catholic convents and monasteries across Mexico, Italy and France, in schools in Kosovo and even among cheerleaders in a rural North Carolina town.

Episodes of mass hysteria has been observed in schools of Nepal frequently, even leading to closure of schools temporarily. A unique phenomenon of “recurrent epidemic of mass hysteria” was reported from a school of Pyuthan district of western Nepal in 2018. After a 9 year old school girl developed crying and shouting episodes, quickly other children of the same school were also affected resulting in 47 affected students (37 females, 10 males) in the same day. Since 2016 similar episodes of mass psychogenic illness has been occurring in the same school every year hence it was thought to be a unique case of recurrent mass hysteria.

Terrorism and biological warfare

Bartholomew and Wessely anticipate the "concern that after a chemical, biological or nuclear attack, public health facilities may be rapidly overwhelmed by the anxious and not just the medical and psychological casualties." Additionally, early symptoms of those affected by MPI are difficult to differentiate from those actually exposed to the dangerous agent.

The first Iraqi missile hitting Israel during the Persian Gulf War was believed to contain chemical or biological weapons. Though this was not the case, 40% of those in the vicinity of the blast reported breathing problems.

Right after the 2001 anthrax attacks in the first two weeks of October 2001, there were over 2300 false anthrax alarms in the United States. Some reported physical symptoms of what they believed to be anthrax.

Also in 2001, a man sprayed what was later found to be a window cleaner into a subway station in Maryland. Thirty-five people were treated for nausea, headaches and sore throats.

In 2017, some employees of the US embassy in Cuba reported symptoms (nicknamed the "Havana syndrome") attributed to "sonic attacks". The following year, some US government employees in China reported similar symptoms. Some scientists have suggested the alleged symptoms were psychogenic in nature.

Children in recent refugee families

Refugee children in Sweden have been reported to fall into coma-like states on learning their families will be deported. The condition, known as resignation syndrome (Swedish: uppgivenhetssyndrom), is believed to only exist among the refugee population in the Scandinavian country, where it has been prevalent since the early part of the 21st century. Commentators state "a degree of psychological contagion" is inherent to the condition, by which young friends and relatives of the afflicted individual can also come to suffer from the condition.

In a 130 page report on the condition, commissioned by the government and published in 2006, a team of psychologists, political scientists and sociologists hypothesized that it was a culture-bound syndrome, a psychological illness endemic to a specific society. 

This phenomenon has later been called into question, with children witnessing that they were forced, by their parents, to act in a certain way in order to increase chances of being granted residence permits. As evidenced by medical records, healthcare professionals were aware of this scam, and witnessed parents who actively refused aid for their children, but remained silent. Later, Sveriges Television, Sweden's national public television broadcaster, were severely critiqued by investigative journalist Janne Josefsson for failing to uncover the truth.

Chemtrail conspiracy theory

From Wikipedia, the free encyclopedia

The chemtrail conspiracy theory posits the erroneous belief that long-lasting condensation trails are "chemtrails" consisting of chemical or biological agents left in the sky by high-flying aircraft, sprayed for nefarious purposes undisclosed to the general public. Believers in this conspiracy theory say that while normal contrails dissipate relatively quickly, contrails that linger must contain additional substances. Those who subscribe to the theory speculate that the purpose of the chemical release may be solar radiation management, weather modification, psychological manipulation, human population control, biological or chemical warfare, or testing of biological or chemical agents on a population, and that the trails are causing respiratory illnesses and other health problems.

The claim has been dismissed by the scientific community. There is no evidence that purported chemtrails differ from normal water-based contrails routinely left by high-flying aircraft under certain atmospheric conditions. Although proponents have tried to prove that chemical spraying occurs, their analyses have been flawed or based on misconceptions. Because of the persistence of the conspiracy theory and questions about government involvement, scientists and government agencies around the world have repeatedly explained that the supposed chemtrails are in fact normal contrails.

The term chemtrail is a portmanteau of the words chemical and trail, just as contrail is a portmanteau of condensation and trail.

History

Multiple concurrent contrails. How long they last depends upon the weather, especially the temperature, humidity, and wind speed.

Chemtrail conspiracy theories began to circulate after the United States Air Force (USAF) published a 1996 report about weather modification. Following the report, in the late 1990s the USAF was accused of "spraying the U.S. population with mysterious substances" from aircraft "generating unusual contrail patterns." The theories were posted on Internet forums by people including Richard Finke and William Thomas, and were among many conspiracy theories popularized by late-night radio host Art Bell, starting in 1999. As the chemtrail conspiracy theory spread, federal officials were flooded with angry calls and letters.

A multi-agency response attempting to dispel the rumors was published in 2000 by the Environmental Protection Agency (EPA), the Federal Aviation Administration (FAA), the National Aeronautics and Space Administration (NASA) and the National Oceanic and Atmospheric Administration (NOAA). Many chemtrail believers interpreted agency fact sheets as further evidence of the existence of a government cover-up. The EPA refreshed its posting in 2015.

In the early 2000s the USAF released an undated fact sheet that stated the conspiracy theories were a hoax fueled in part by citations to a 1996 strategy paper drafted within their Air University titled Weather as a Force Multiplier: Owning the Weather in 2025. The paper was presented in response to a military directive to outline a future strategic weather modification system for the purpose of maintaining the United States' military dominance in the year 2025, and identified as "fictional representations of future situations/scenarios." The USAF further clarified in 2005 that the paper "does not reflect current military policy, practice, or capability," and that it is "not conducting any weather modification experiments or programs and has no plans to do so in the future." Additionally, the USAF states that the "'Chemtrail' hoax has been investigated and refuted by many established and accredited universities, scientific organizations, and major media publications."

The conspiracy theories are seldom covered by the mainstream media, and when they are, they are usually cast as an example of anti-government paranoia. For example, in 2013, when it was made public that the CIA, NASA, and NOAA intended to provide funds to the National Academy of Sciences to conduct research into methods to counteract global warming with geoengineering, an article in the International Business Times anticipated that "the idea of any government agency looking at ways to control, or manipulate, the weather will be met with scrutiny and fears of a malign conspiracies" [sic], and mentioned chemtrail conspiracy theories as an example.

Description

Proponents of the chemtrail conspiracy theory find support for their theories in their interpretations of sky phenomena, videos posted to the internet, and reports about government programs; they also have certain beliefs about the goals of the alleged conspiracy and the effects of its alleged efforts and generally take certain actions based on those beliefs.

Interpretation of evidence

Proponents of the chemtrail conspiracy theory say that chemtrails can be distinguished from contrails by their long duration, asserting that the chemtrails are those trails left by aircraft that persist for as much as a half-day or transform into cirrus-like clouds. The proponents claim that after 1995 contrails had a different chemical composition and lasted a lot longer on the sky; proponents fail to acknowledge evidence of long-lasting contrails shown in World War II–era photographs.

Proponents characterize contrails as streams that persist for hours and that, with their criss-cross, grid-like or parallel stripe patterns, eventually blend to form large clouds. Proponents view the presence of visible color spectra in the streams, unusual concentrations of sky tracks in a single area, or lingering tracks left by unmarked or military airplanes flying at atypical altitudes or locations as markers of chemtrails.

Photographs of barrels installed in the passenger space of an aircraft for flight test purposes have been claimed to show aerosol dispersion systems. The real purpose of the barrels is to simulate the weight of passengers or cargo. The barrels are filled with water, and the water can be pumped from barrel to barrel in order to test different centers of gravity while the aircraft is in flight.

Former CIA employee and whistleblower Edward Snowden, interviewed on "The Joe Rogan Experience", stated that he had searched through all the secret information of the US government for evidence about (aliens and) chemtrails. According to a CNN report about the webcast he said: "In case you were wondering: ... Chemtrails are not a thing," and: "I had ridiculous access to the networks of the NSA, the CIA, the military, all these groups. I couldn't find anything"

Jim Marrs has cited a 2007 Louisiana television station report as evidence for chemtrails. In the report the air underneath a crosshatch of supposed chemtrails was measured and apparently found to contain unsafe levels of barium: at 6.8 parts per million, three times the US nationally recommended limit. A subsequent analysis of the footage showed, however, that the equipment had been misused, and the reading exaggerated by a factor of 100—the true level of barium measured was both usual and safe.

In May 2014 a video that went viral showed a commercial passenger airplane landing on a foggy night, which was described as emitting chemtrails. Discovery News pointed out that passengers sitting behind the wings would clearly see anything being sprayed, which would defeat any intent to be secretive, and that the purported chemical emission was normal air disruption caused by the wings, visible due to the fog. In October 2014, Englishman Chris Bovey filmed a video of a plane jettisoning fuel on a flight from Buenos Aires to London, which had to dump fuel to lighten its load for an emergency landing in São Paulo. The clip went viral on Facebook, with over three million views and more than 52,000 shares, cited as evidence of chemtrails. He later disclosed that the video post was done as a prank, and consequently, he was subjected to some vitriolic abuse and threats from several conspiracy believers.

In some accounts, the chemicals are described as barium and aluminum salts, polymer fibers, thorium, or silicon carbide.

Chemtrail believers interpret the existence of cloud seeding programs and research into climate engineering as evidence for the conspiracy.

Beliefs

Various versions of the chemtrail conspiracy theory have been propagated via the Internet and radio programs. There are websites dedicated to the conspiracy theory, and it is particularly favored by far right groups because it fits well with deep suspicion of government.

A 2014 review of 20 chemtrail websites found that believers appeal to science in some of their arguments, but do not believe what academic or government-employed scientists say; scientists and federal agencies have consistently denied that chemtrails exist, explaining the sky tracks are simply persistent contrails. The review also found that believers generally hold that chemtrails are evidence of a global conspiracy; they allege various goals which include profit (for example, manipulating futures prices, or making people sick to benefit drug companies), population control, or weapons testing (use of weather as a weapon, or testing bioweapons). One of these ideas is that clouds are being seeded with electrically conductive materials as part of a massive electromagnetic superweapons program based around the High Frequency Active Auroral Research Program (HAARP). Believers say chemtrails are toxic; the 2014 review found that they generally hold that every person is under attack and often express fear, anxiety, sadness, and anger about this. A 2011 study of people from the US, Canada, and the UK found that 2.6% of the sample believed entirely in the conspiracy theory, and 14% believed it partially. An analysis of responses given to the 2016 Cooperative Congressional Election Study showed that 9% of the 36,000 respondents believed it was "completely true" that "...the government has a secret program that uses airplanes to put harmful chemicals into the air..." while a further 19% believed this was "somewhat true".

Actions

Chemtrail conspiracy theorists often describe their experience as being akin to a religious conversion experience. When they "wake up" and become "aware" of chemtrails, the experience motivates them to advocacy of various forms. For example, they often attend events and conferences on geoengineering, and have sent threats to academics working in the geoengineering field.

In 2001 in response to requests from constituents, US Congressman Dennis Kucinich introduced (but did not author) H.R. 2977 (107th), the Space Preservation Act of 2001 that would have permanently prohibited the basing of weapons in space, listing chemtrails as one of a number of "exotic weapons" that would be banned. Proponents have interpreted this explicit reference to chemtrails as official government acknowledgment of their existence. Skeptics note that the bill in question also mentions "extraterrestrial weapons" and "environmental, climate, or tectonic weapons." The bill received an unfavorable evaluation from the United States Department of Defense and died in committee, with no mention of chemtrails appearing in the text of any of the three subsequent failed attempts by Kucinich to enact a Space Preservation Act.

In 2003, in a response to a petition by concerned Canadian citizens regarding "chemicals used in aerial sprayings are adversely affecting the health of Canadians," the Government House Leader responded by stating, "There is no substantiated evidence, scientific or otherwise, to support the allegation that there is high altitude spraying conducted in Canadian airspace. The term 'chemtrails' is a popularised expression, and there is no scientific evidence to support their existence." The house leader went on to say that "it is our belief that the petitioners are seeing regular airplane condensation trails, or contrails."

In the United Kingdom, in 2005 Elliot Morley, a Minister of State for the Department for Environment, Food and Rural Affairs was asked by David Drew, the Labour Party Member of Parliament for Stroud, "what research [the] Department has undertaken into the polluting effects of chemtrails for aircraft," and responded that "the Department is not researching into chemtrails from aircraft as they are not scientifically recognised phenomena," and that work was being conducted to understand "how contrails are formed and what effects they have on the atmosphere."

Some chemtrail believers adopt the notions of Wilhelm Reich (1897–1957) who devised a "cloudbuster" device from pipework. Reich claimed this device would influence weather and remove harmful energy from the atmosphere. Some chemtrail believers have built cloudbusters filled with crystals and metal filings, which are pointed at the sky in an attempt to clear it of chemtrails.

Chemtrail believers sometimes gather samples and have them tested, rather than rely on reports from government or academic laboratories, but their experiments are usually flawed; for example collecting samples in jars with metal lids contaminates the sample and is not done in scientific testing.

Contrails

Contrails from propeller-driven aircraft engine exhaust, early 1940s

Contrails, or condensation trails, are "streaks of condensed water vapor created in the air by an airplane or rocket at high altitudes." Fossil fuel combustion (as in piston and jet engines) produces carbon dioxide and water vapor. At high altitudes the air is very cold. Hot humid air from the engine exhaust mixes with the colder surrounding air, causing the water vapor to condense into droplets or ice crystals that form visible clouds. The rate at which contrails dissipate is entirely dependent on weather conditions. If the atmosphere is near saturation, the contrail may exist for some time. Conversely, if the atmosphere is dry, the contrail will dissipate quickly.

It is well established by atmospheric scientists that contrails can persist for hours, and that it is normal for them to spread out into cirrus sheets. The different-sized ice crystals in contrails descend at different rates, which spreads the contrail vertically. Then the differential in wind speeds between altitudes (wind shear) results in horizontal spreading of the contrail. This mechanism is similar to the formation of cirrus uncinus clouds. Contrails between 25,000 and 40,000 feet (7,600 and 12,200 m) can often merge into an "almost solid" interlaced sheet. Contrails can have a lateral spread of several kilometers, and given sufficient air traffic, it is possible for contrails to create an entirely overcast sky that increases the ice budget of individual contrails and persists for hours.

Experts on atmospheric phenomena say that the characteristics attributed to chemtrails are simply features of contrails responding to diverse conditions in terms of sunlight, temperature, horizontal and vertical wind shear, and humidity levels present at the aircraft's altitude. In the US, the gridlike nature of the National Airspace System's flight lanes tends to cause crosshatched contrails, and in general it is hard to discern from the ground whether overlapping contrails are at similar altitudes or not. The jointly published fact sheet produced by NASA, the EPA, the FAA, and NOAA in 2000 in response to alarms over chemtrails details the science of contrail formation, and outlines both the known and potential impacts contrails have on temperature and climate. The USAF produced a fact sheet that described these contrail phenomena as observed and analyzed since at least 1953. It also rebutted chemtrail theories more directly by identifying the theories as a hoax and disproving the existence of chemtrails.

Patrick Minnis, an atmospheric scientist with NASA's Langley Research Center in Hampton, Virginia, has said that logic does not dissuade most chemtrail proponents: "If you try to pin these people down and refute things, it's, 'Well, you're just part of the conspiracy'," he said.

Analysis of the use of commercial aircraft tracks for climate engineering has shown them to be generally unsuitable.

Astronomer Bob Berman has characterized the chemtrail conspiracy theory as a classic example of failure to apply Occam's razor, writing in 2009 that instead of adopting the long-established "simple solution" that the trails consist of frozen water vapour, "the conspiracy web sites think the phenomenon started only a decade ago and involves an evil scheme in which 40,000 commercial pilots and air traffic controllers are in on the plot to poison their own children."

A 2016 survey of 77 atmospheric scientists concluded that "76 out of 77 (98.7%) of scientists that took part in this study said there was no evidence of a [secret large-scale atmospheric program (SLAP)], and that the data cited as evidence could be explained through other factors, such as typical contrail formation and poor data sampling instructions presented on SLAP websites."
