John Burdon Sanderson Haldane FRS (/ˈhɔːldn/; 5 November 1892 – 1 December 1964) was a British-Indian scientist known for his work in the study of physiology, genetics, evolutionary biology, and mathematics. He made innovative contributions to the fields of statistics and biostatistics.

His article on abiogenesis in 1929 introduced the "primordial soup theory", and it became the foundation to build physical models for the chemical origin of life. Haldane established human gene maps for haemophilia and colour blindness on the X chromosome, and codified Haldane's rule on sterility in the heterogametic sex of hybrids in species. He correctly proposed that sickle-cell disease confers some immunity to malaria. He was the first to suggest the central idea of in vitro fertilisation, as well as concepts such as hydrogen economy, cis and trans-acting regulation, coupling reaction, molecular repulsion, the darwin (as a unit of evolution) and organismal cloning. In 1957 he articulated Haldane's dilemma, a limit on the speed of beneficial evolution which subsequently proved incorrect. He willed his body for medical studies, as he wanted to remain useful even in death. He is also remembered for coining the words "clone" and "cloning" in human biology, and "ectogenesis".

Haldane's first paper in 1915 demonstrated genetic linkage in mammals. Subsequent works established a unification of Mendelian genetics and Darwinian evolution by natural selection whilst laying the groundwork for modern evolutionary synthesis and thus helped to create population genetics.

Haldane was a professed socialist, Marxist, atheist and humanist whose political dissent led him to leave England in 1956 and live in India, becoming a naturalised Indian citizen in 1961. He was the son of John Scott Haldane.

Arthur C. Clarke credited him as "perhaps the most brilliant science populariser of his generation". Nobel laureate Peter Medawar called Haldane "the cleverest man I ever knew". According to Theodosius Dobzhansky, "Haldane was always recognized as a singular case"; and to Michael J. D. White, "the most erudite biologist of his generation, and perhaps of the century."

Biography

His father John Scott Haldane c. 1910

Early life and education

Haldane was born in Oxford to John Scott Haldane, a physiologist, scientist, a philosopher and a Liberal, and Louisa Kathleen Trotter, a Conservative. His younger sister, Naomi Mitchison, became a writer, and his uncle was Viscount Haldane and his aunt the author Elizabeth Haldane. Descended from an aristocratic and secular family of the Clan Haldane, he would later claim that his Y chromosome could be traced back to Robert the Bruce.

He grew up at 11 Crick Road, North Oxford. He learnt to read at the age of three, and at four, after injuring his forehead he asked the doctor, "Is this oxyhaemoglobin or carboxyhaemoglobin?". From age eight he worked with his father in their home laboratory where he experienced his first self-experimentation, the method he would later be famous for. He and his father became their own "human guinea pigs", such as in their investigation on the effects of poison gases. In 1899 his family moved to "Cherwell", a late Victorian house at the outskirts of Oxford with its own private laboratory.
His formal education began in 1897 at Oxford Preparatory School (now Dragon School), where he gained a First Scholarship in 1904 to Eton. In 1905 he joined Eton, where he experienced severe abuse from senior students for allegedly being arrogant. The indifference of authority left him with a lasting hatred for the English education system. However, the ordeal did not stop him from becoming Captain of the school. He studied mathematics and classics at New College at the University of Oxford and obtained first-class honours in mathematical moderations in 1912 and first-class honours in Greats in 1914. He became engrossed in genetics and presented a paper on gene linkage in vertebrates in the summer of 1912. His first technical paper, a 30-page long article on haemoglobin function, was published that same year, as a co-author alongside his father.

Career

His education was interrupted by the First World War during which he fought in the British Army, being commissioned a temporary second lieutenant in the 3rd Battalion of the Black Watch (Royal Highland Regiment) on 15 August 1914. He was promoted to temporary lieutenant on 18 February 1915 and to temporary captain on 18 October. He served in France and Iraq, where he was wounded. He relinquished his commission on 1 April 1920, retaining his rank of captain. For his ferocity and aggressiveness in battles, his commander called him the "bravest and dirtiest officer in my Army."

Between 1919 and 1922 he was a Fellow of New College, Oxford, where he researched physiology and genetics. He then moved to the University of Cambridge, where he accepted a readership in Biochemistry and taught until 1932. From 1927 until 1937 he was also Head of Genetical Research at the John Innes Horticultural Institution. During his nine years at Cambridge, Haldane worked on enzymes and genetics, particularly the mathematical side of genetics. He was the Fullerian Professor of Physiology at the Royal Institution from 1930 to 1932 and in 1933 he became full Professor of Genetics at University College London, where he spent most of his academic career. Four years later he became the first Weldon Professor of Biometry at University College London.

In 1924, Haldane met Charlotte Franken. So that they could marry, Charlotte divorced her husband, Jack Burghes, causing some controversy. Haldane was almost dismissed from Cambridge for the way he handled his meeting with her. They married in 1926. Following their separation in 1942, the Haldanes divorced in 1945. Later that year he married Helen Spurway.

Haldane, inspired by his father, would expose himself to danger to obtain data. To test the effects of acidification of the blood he drank dilute hydrochloric acid, enclosed himself in an airtight room containing 7% carbon dioxide, and found that it 'gives one a rather violent headache'. One experiment to study elevated levels of oxygen saturation triggered a fit which resulted in him suffering crushed vertebrae. In his decompression chamber experiments, he and his volunteers suffered perforated eardrums. But, as Haldane stated in What is Life, "the drum generally heals up; and if a hole remains in it, although one is somewhat deaf, one can blow tobacco smoke out of the ear in question, which is a social accomplishment."

In India

In 1956, Haldane left University College London, and joined the Indian Statistical Institute (ISI) in Kolkata, India, where he headed the biometry unit. Officially he stated that he left the UK because of the Suez Crisis, writing: "Finally, I am going to India because I consider that recent acts of the British Government have been violations of international law." He believed that the warm climate would do him good, and that India shared his socialist dreams. The university had sacked his wife Helen for excessive drinking and refusing to pay a fine, triggering Haldane's resignation. He declared he would no longer wear socks, "Sixty years in socks is enough." and always dressed in Indian attire.

He was keenly interested in inexpensive research. He wrote to Julian Huxley about his observations on Vanellus malabaricus, the yellow-wattled lapwing. He advocated the use of Vigna sinensis (cowpea) as a model for studying plant genetics. He took an interest in the pollination of Lantana camara. He lamented that Indian universities forced those who took up biology to drop mathematics. Haldane took an interest in the study of floral symmetry. In January 1961 he befriended Gary Botting, 1960 U.S. Science Fair winner in zoology (who had first visited the Haldanes along with Susan Brown, 1960 U.S. National Science Fair winner in botany), inviting him to share the results of his experiments hybridising Antheraea silk moths. J.B.S., his wife Helen Spurway, and Krishna Dronamraju were present at the Oberoi Grand Hotel in Kolkata when Brown reminded the Haldanes that she and Botting had a previously scheduled event that would prevent them from accepting an invitation to a banquet proposed by J.B.S. and Helen in their honour and had regretfully declined the honour. After the two students had left the hotel, Haldane went on his much-publicized hunger strike to protest what he regarded as a "U.S. insult." When the director of the ISI, P. C. Mahalanobis, confronted Haldane about both the hunger strike and the unbudgeted banquet, Haldane resigned from his post (in February 1961), and moved to a newly established biometry unit in Odisha.

Haldane took Indian citizenship; he was interested in Hinduism and became a vegetarian. In 1961, Haldane described India as "the closest approximation to the Free World." Jerzy Neyman objected that "India has its fair share of scoundrels and a tremendous amount of poor unthinking and disgustingly subservient individuals who are not attractive." Haldane retorted:
Perhaps one is freer to be a scoundrel in India than elsewhere. So one was in the U.S.A in the days of people like Jay Gould, when (in my opinion) there was more internal freedom in the U.S.A than there is today. The "disgusting subservience" of the others has its limits. The people of Calcutta riot, upset trams, and refuse to obey police regulations, in a manner which would have delighted Jefferson. I don't think their activities are very efficient, but that is not the question at issue.
When on 25 June 1962 he was described in print as a "Citizen of the World" by Groff Conklin, Haldane's response was as follows:
No doubt I am in some sense a citizen of the world. But I believe with Thomas Jefferson that one of the chief duties of a citizen is to be a nuisance to the government of his state. As there is no world state, I cannot do this. On the other hand, I can be, and am, a nuisance to the government of India, which has the merit of permitting a good deal of criticism, though it reacts to it rather slowly. I also happen to be proud of being a citizen of India, which is a lot more diverse than Europe, let alone the U.S.A, the U.S.S.R or China, and thus a better model for a possible world organisation. It may of course break up, but it is a wonderful experiment. So, I want to be labeled as a citizen of India.

Death

Shortly before his death from cancer, Haldane wrote a comic poem while in the hospital, mocking his own incurable disease. It was read by his friends, who appreciated the consistent irreverence with which Haldane had lived his life. The poem first appeared in print in 21 February 1964 issue of the New Statesman, and runs:
Cancer's a Funny Thing:
I wish I had the voice of Homer
To sing of rectal carcinoma,
This kills a lot more chaps, in fact,
Than were bumped off when Troy was sacked ...
The poem ends:
... I know that cancer often kills,
But so do cars and sleeping pills;
And it can hurt one till one sweats,
So can bad teeth and unpaid debts.
A spot of laughter, I am sure,
Often accelerates one's cure;
So let us patients do our bit
To help the surgeons make us fit.
Haldane died on 1 December 1964 in Bhubaneswar. He willed that his body be used for medical research and teaching  at the Rangaraya Medical College, Kakinada.
My body has been used for both purposes during my lifetime and after my death, whether I continue to exist or not, I shall have no further use for it, and desire that it shall be used by others. Its refrigeration, if this is possible, should be a first charge on my estate.

Academic achievements

Following his father's footsteps, Haldane's first publication was on the mechanism of gaseous exchange by haemoglobin. and subsequently worked on the chemical properties of blood as a pH buffer. He investigated several aspects of kidney functions and mechanism of excretion.

Enzyme kinetics

In 1925, with G. E. Briggs, Haldane derived a new interpretation of the enzyme kinetics law described by Victor Henri in 1903, different from the 1913 Michaelis–Menten equation. Leonor Michaelis and Maud Menten assumed that enzyme (catalyst) and substrate (reactant) are in fast equilibrium with their complex, which then dissociates to yield product and free enzyme. The Briggs–Haldane equation was of the same algebraic form; but their derivation is based on the quasi-steady state approximation, which is the concentration of intermediate complex (or complexes) does not change. As a result, the microscopic meaning of the "Michaelis Constant" (Km) is different. Although commonly referring to it as Michaelis–Menten kinetics, most of the current models typically use the Briggs–Haldane derivation.

Genetic linkage

With his sister Naomi Mitchison, Haldane started investigating Mendelian genetics in 1908, used guinea pigs and mice, publishing Reduplication in mice in 1915 the first demonstration of genetic linkage in mammals, showing that certain genetic traits tend to be inherited together (as was later discovered, because of their proximity on chromosomes). As the paper was written during Haldane's service in the First World War, James F. Crow called it "the most important science article ever written in a front-line trench". He was the first to demonstrate linkage in chickens in 1921, and (with Julia Bell) in humans in 1937.

Haldane's principle

In his essay On Being the Right Size he outlines Haldane's principle, which states that the size very often defines what bodily equipment an animal must have: "Insects, being so small, do not have oxygen-carrying bloodstreams. What little oxygen their cells require can be absorbed by simple diffusion of air through their bodies. But being larger means an animal must have complicated oxygen pumping and distributing systems to reach all the cells." The conceptual metaphor to animal allometry has been of use in energy economics and secession ideas.

Origin of life

Haldane introduced the modern concept of abiogenesis in an eight-page article titled The origin of life, in the Rationalist Annual in 1929, describing the primitive ocean as a "vast chemical laboratory" containing a mixture of inorganic compounds – like a "hot dilute soup" in which organic compounds could have formed. Under the solar energy the anoxic atmosphere containing carbon dioxide, ammonia and water vapour gave rise to a variety of organic compounds, "living or half-living things". The first molecules reacted with one another to produce more complex compounds, and ultimately the cellular components. At some point a kind of "oily film" was produced that enclosed self-replicating nucleic acids, thereby becoming the first cell. J. D. Bernal named the hypothesis biopoiesis or biopoesis, the process of living matter spontaneously evolving from self-replicating but lifeless molecules. Haldane further hypothesised that viruses were the intermediate entities between the prebiotic soup and the first cells. He asserted that prebiotic life would have been "in the virus stage for many millions of years before a suitable assemblage of elementary units was brought together in the first cell." The idea was generally dismissed as "wild speculation". Alexander Oparin had suggested a similar idea in Russian in 1924 (published in English in 1936). The gained some empirical support in 1953 with the classic Miller–Urey experiment. Since then, the primordial soup theory (Oparin–Haldane hypothesis) has become prevalent in the study of abiogenesis.

Malaria and Sickle-Cell Anemia

In 1949, Haldane proposed that genetic disorders in humans living in malaria-endemic regions provided a phenotype with immunity to blood-borne haemophiles. He noted that mutations expressed in red blood cells, such as sickle-cell anemia and various thalassemias, were prevalent only in tropical regions where malaria has been endemic. He further observed that these were favourable traits for natural selection which protected individuals from receiving malarial infection. This idea was eventually confirmed by Anthony C. Allison in 1954.

Population genetics

He was one of the three major figures to develop the mathematical theory of population genetics, along with Ronald Fisher and Sewall Wright. He thus played an important role in the modern evolutionary synthesis of the early 20th century. He re-established natural selection as the central mechanism of evolution by explaining it as a mathematical consequence of Mendelian inheritance. He wrote a series of ten papers, A Mathematical Theory of Natural and Artificial Selection, deriving expressions for the direction and rate of change of gene frequencies, and also analyzing the interaction of natural selection with mutation and migration. Haldane's book, The Causes of Evolution (1932), summarised these results, especially in its extensive appendix.

His contributions to statistical human genetics included: the first methods using maximum likelihood for the estimation of human linkage maps; pioneering methods for estimating human mutation rates; the first estimates of mutation rate in humans (2 × 10−5 mutations per gene per generation for the X-linked haemophilia gene); and the first notion that there is a "cost of natural selection". At the John Innes Horticultural Institution, he developed the complicated linkage theory for polyploids; and extended the idea of gene/enzyme relationships with the biochemical and genetic study of plant pigments.

Political views

Haldane became a socialist during the First World War; supported the Second Spanish Republic during the Spanish Civil War; and then became an open supporter of the Communist Party in 1937. A pragmatic dialectical-materialist Marxist, he wrote many articles for the Daily Worker. In On Being the Right Size, he wrote: "while nationalization of certain industries is an obvious possibility in the largest of states, I find it no easier to picture a completely socialized British Empire or United States than an elephant turning somersaults or a hippopotamus jumping a hedge."

Haldane has been accused by authors including Peter Wright and Chapman Pincher to have been a Soviet GRU spy codenamed Intelligentsia.

In 1938, he proclaimed enthusiastically that "I think that Marxism is true." He joined the Communist Party of Great Britain in 1942. He was pressed to speak out about the rise of Lysenkoism and the persecution of geneticists in the Soviet Union as anti-Darwinist and the political suppression of genetics as incompatible with dialectical materialism. He shifted his polemic focus to the United Kingdom, criticizing the dependence of scientific research on financial patronage. In 1941 he wrote about the Soviet trial of his friend and fellow geneticist Nikolai Vavilov:
The controversy among Soviet geneticists has been largely one between the academic scientist, represented by Vavilov and interested primarily in the collection of facts, and the man who wants results, represented by Lysenko. It has been conducted not with venom, but in a friendly spirit. Lysenko said (in the October discussions of 1939): 'The important thing is not to dispute; let us work in a friendly manner on a plan elaborated scientifically. Let us take up definite problems, receive assignments from the People's Commissariat of Agriculture of the USSR and fulfil them scientifically. Soviet genetics, as a whole, is a successful attempt at synthesis of these two contrasted points of view.'
By the end of the Second World War Haldane had become an explicit critic of the regime. He left the party in 1950, shortly after considering standing for Parliament as a Communist Party candidate. He continued to admire Joseph Stalin, describing him in 1962 as "a very great man who did a very good job".

Social and scientific views

Human cloning

Haldane was the first to have thought of the genetic basis for human cloning, and the eventual artificial breeding of superior individuals. For this he introduced the terms "clone" and "cloning", modifying the earlier "clon" which had been used in agriculture since the early 20th century (from Greek klon, twig). He introduced the term in his speech on "Biological Possibilities for the Human Species of the Next Ten Thousand Years" at the Ciba Foundation Symposium on Man and his Future in 1963. He said:
It is extremely hopeful that some human cell lines can be grown on a medium of precisely known chemical composition. Perhaps the first step will be the production of a clone from a single fertilized egg, as in Brave New World...
On the general principle that men will make all possible mistakes before choosing the right path, we shall no doubt clone the wrong people [like Hitler]...
Assuming that cloning is possible, I expect that most clones would be made from people aged at least fifty, except for athletes
and dancers, who would be cloned younger. They would be made from people who were held to have excelled in a socially acceptable accomplishment.

Ectogenesis and in vitro fertilisation

His essay Daedalus; or, Science and the Future (1924) introduced the term ectogenesis for the concept of what is later known as in vitro fertilisation (test tube babies). He envisioned ectogenesis as a tool for creating better individuals (eugenics). Haldane's work was an influence on Huxley's Brave New World (1932) and was also admired by Gerald Heard. Various essays on science were collected and published in a volume titled Possible Worlds in 1927. His book, A.R.P. (Air Raid Precautions) (1938) combined his physiological research into the effects of stress upon the human body with his experience of air raids during the Spanish Civil War to provide a scientific account of the likely effects of the air raids that Britain was to endure during the Second World War.

Criticism of C.S. Lewis

Along with Olaf Stapledon, Charles Kay Ogden, I. A. Richards, and H. G. Wells, Haldane was accused by C. S. Lewis of scientism. Haldane criticised Lewis and his Ransom Trilogy for the "complete mischaracterisation of science, and his disparagement of the human race". He wrote a book for children titled My Friend Mr Leakey (1937), containing the stories "A Meal With a Magician", "A Day in the Life of a Magician", "Mr Leakey's Party", "Rats", "The Snake with the Golden Teeth", and "My Magic Collar Stud"; later editions featured illustrations by Quentin Blake.

Hydrogen-generating windmills

In 1923, in a talk given in Cambridge titled "Science and the Future", Haldane, foreseeing the exhaustion of coal for power generation in Britain, proposed a network of hydrogen-generating windmills. This is the first proposal of the hydrogen-based renewable energy economy.

Scientists

In his An Autobiography in Brief, published shortly before his death in India, Haldane named four close associates as showing promise to become illustrious scientists: T. A. Davis, Dronamraju Krishna Rao, Suresh Jayakar and S. K. Roy.

Awards and honours

Haldane was elected a Fellow of the Royal Society in 1932. The French Government conferred him its National Order of the Legion of Honour in 1937. In 1952, he received the Darwin Medal from the Royal Society. In 1956, he was awarded the Huxley Memorial Medal of the Anthropological Institute of Great Britain. He received the Feltrinelli Prize from Accademia Nazionale dei Lincei in 1961. He also received an Honorary Doctorate of Science, an Honorary Fellowship at New College, and the Kimber Award of the US National Academy of Sciences. He was awarded the Linnean Society of London's prestigious Darwin–Wallace Medal in 1958.

Legacy

The Haldane Lecture at the John Innes Centre, where Haldane worked from 1927 to 1937 is named in his honour. The JBS Haldane Lecture of The Genetics Society is also named in his honour. 

Haldane was parodied as "the biologist too absorbed in his experiments to notice his friends bedding his wife" by his friend Aldous Huxley in the novel Antic Hay (1923). Biography on him was published as A Dominant Character in 2019.

Quotations

Oxford University Museum of Natural History display dedicated to Haldane and his reply when asked to comment on the mind of the Creator.
  • He is famous for the (possibly apocryphal) response that he gave when some theologians asked him what could be inferred about the mind of the Creator from the works of His Creation: "An inordinate fondness for beetles." This is in reference to there being over 400,000 known species of beetles in the world, and that this represents 40% of all known insect species (at the time of the statement, it was over half of all known insect species).
  • He was often quoted as saying, "My own suspicion is that the universe is not only queerer than we suppose, but queerer than we can suppose."
  • "It seems to me immensely unlikely that mind is a mere by-product of matter. For if my mental processes are determined wholly by the motions of atoms in my brain I have no reason to suppose that my beliefs are true. They may be sound chemically, but that does not make them sound logically. And hence I have no reason for supposing my brain to be composed of atoms."
  • "Teleology is like a mistress to a biologist: he cannot live without her but he's unwilling to be seen with her in public."
  • "I had gastritis for about fifteen years until I read Lenin and other writers, who showed me what was wrong with our society and how to cure it. Since then I have needed no magnesia."
  • "I suppose the process of acceptance will pass through the usual four stages: (i) This is worthless nonsense; (ii) This is an interesting, but perverse, point of view; (iii) This is true, but quite unimportant; (iv) I always said so."
  • "Three hundred and ten species in all of India, representing two hundred and thirty-eight genera, sixty-two families, nineteen different orders. All of them on the Ark. And this is only India, and only the birds."
  • "The stupidity of the mynah shows that in birds, as in men, linguistic and practical abilities are not very highly correlated. A student who can repeat a page of a text book may get first class honours, but may be incapable of doing research."
  • When asked whether he would lay down his life for his brother, Haldane, presaging Hamilton's rule, supposedly replied "two brothers or eight cousins".

Vitalism

From Wikipedia, the free encyclopedia
The synthesis of urea in the early 19th century from inorganic compounds was counterevidence for the vitalist hypothesis that only organisms could make the components of living things.

Vitalism is the belief that "living organisms are fundamentally different from non-living entities because they contain some non-physical element or are governed by different principles than are inanimate things". Where vitalism explicitly invokes a vital principle, that element is often referred to as the "vital spark", "energy" or "élan vital", which some equate with the soul. In the 18th and 19th centuries vitalism was discussed among biologists, between those who felt that the known mechanics of physics would eventually explain the difference between life and non-life and vitalists who argued that the processes of life could not be reduced to a mechanistic process. Some vitalist biologists proposed testable hypotheses meant to show inadequacies with mechanistic explanations, but these experiments failed to provide support for vitalism. Biologists now consider vitalism in this sense to have been refuted by empirical evidence, and hence regard it as a superseded scientific theory.

Vitalism has a long history in medical philosophies: many traditional healing practices posited that disease results from some imbalance in vital forces.

History

Ancient times

The notion that bodily functions are due to a vitalistic principle existing in all living creatures has roots going back at least to ancient Egypt. In Greek philosophy, the Milesian school proposed natural explanations deduced from materialism and mechanism. However, by the time of Lucretius, this account was supplemented, (for example, by the unpredictable clinamen of Epicurus), and in Stoic physics, the pneuma assumed the role of logos. Galen believed the lungs draw pneuma from the air, which the blood communicates throughout the body.

Medieval

In Europe, medieval physics was influenced by the idea of pneuma, helping to shape later aether theories.

Early modern

Vitalists included English anatomist Francis Glisson (1597–1677) and the Italian doctor Marcello Malpighi (1628–1694). Caspar Friedrich Wolff (1733–1794) is considered to be the father of epigenesis in embryology, that is, he marks the point when embryonic development began to be described in terms of the proliferation of cells rather than the incarnation of a preformed soul. However, this degree of empirical observation was not matched by a mechanistic philosophy: in his Theoria Generationis (1759), he tried to explain the emergence of the organism by the actions of a vis essentialis (an organizing, formative force), stating "All believers in epigenesis are vitalists." Carl Reichenbach (1788–1869) later developed the theory of Odic force, a form of life-energy that permeates living things. 

In the 17th century, modern science responded to Newton's action at a distance and the mechanism of Cartesian dualism with vitalist theories: that whereas the chemical transformations undergone by non-living substances are reversible, so-called "organic" matter is permanently altered by chemical transformations (such as cooking).

As worded by Charles Birch and John B. Cobb, "the claims of the vitalists came to the fore again" in the 18th century: "[Georg Ernst] Stahl's followers were active as were others, such as the physician genius Francis Xavier Bichat of the Hotel Dieu." However, "Bichat moved from the tendency typical of the French vitalistic tradition to progressively free himself from metaphysics in order to combine with hypotheses and theories which accorded to the scientific criteria of physics and chemistry." John Hunter recognised "a 'living principle' in addition to mechanics."

Johann Friedrich Blumenbach also was influential in establishing epigenesis in the life sciences in 1781 with his publication of Über den Bildungstrieb und das Zeugungsgeschäfte. Blumenbach cut up freshwater Hydra and established that the removed parts would regenerate. He inferred the presence of a "formative drive" (Bildungstrieb) in living matter. But he pointed out that this name,
like names applied to every other kind of vital power, of itself, explains nothing: it serves merely to designate a peculiar power formed by the combination of the mechanical principle with that which is susceptible of modification.

19th century

Louis Pasteur argued that only life could catalyse fermentation. Painting by Albert Edelfelt, 1885

Jöns Jakob Berzelius, one of the early 19th century fathers of modern chemistry, argued that a regulative force must exist within living matter to maintain its functions. Vitalist chemists predicted that organic materials could not be synthesized from inorganic components, but Friedrich Wöhler synthesised urea from inorganic components in 1828. However, contemporary accounts do not support the common belief that vitalism died when Wöhler made urea. This Wöhler Myth, as historian Peter Ramberg called it, originated from a popular history of chemistry published in 1931, which, "ignoring all pretense of historical accuracy, turned Wöhler into a crusader who made attempt after attempt to synthesize a natural product that would refute vitalism and lift the veil of ignorance, until 'one afternoon the miracle happened'".

Between 1833 and 1844, Johannes Peter Müller wrote a book on physiology called Handbuch der Physiologie, which became the leading textbook in the field for much of the nineteenth century. The book showed Müller's commitments to vitalism; he questioned why organic matter differs from inorganic, then proceeded to chemical analyses of the blood and lymph. He describes in detail the circulatory, lymphatic, respiratory, digestive, endocrine, nervous, and sensory systems in a wide variety of animals but explains that the presence of a soul makes each organism an indivisible whole. He also claimed the behavior of light and sound waves showed that living organisms possessed a life-energy for which physical laws could never fully account.

Louis Pasteur (1822–1895) after his famous rebuttal of spontaneous generation, performed several experiments that he felt supported vitalism. According to Bechtel, Pasteur "fitted fermentation into a more general programme describing special reactions that only occur in living organisms. These are irreducibly vital phenomena." Rejecting the claims of Berzelius, Liebig, Traube and others that fermentation resulted from chemical agents or catalysts within cells, Pasteur concluded that fermentation was a "vital action".

20th century

Hans Driesch (1867–1941) interpreted his experiments as showing that life is not run by physicochemical laws. His main argument was that when one cuts up an embryo after its first division or two, each part grows into a complete adult. Driesch's reputation as an experimental biologist deteriorated as a result of his vitalistic theories, which scientists have seen since his time as pseudoscience. Vitalism is a superseded scientific hypothesis, and the term is sometimes used as a pejorative epithet. Ernst Mayr (1904–2005) wrote:
It would be ahistorical to ridicule vitalists. When one reads the writings of one of the leading vitalists like Driesch one is forced to agree with him that many of the basic problems of biology simply cannot be solved by a philosophy as that of Descartes, in which the organism is simply considered a machine... The logic of the critique of the vitalists was impeccable.
Vitalism has become so disreputable a belief in the last fifty years that no biologist alive today would want to be classified as a vitalist. Still, the remnants of vitalist thinking can be found in the work of Alistair Hardy, Sewall Wright, and Charles Birch, who seem to believe in some sort of nonmaterial principle in organisms.
Other vitalists included Johannes Reinke and Oscar Hertwig. Reinke used the word neovitalism to describe his work, claiming that it would eventually be verified through experimentation, and that it was an improvement over the other vitalistic theories. The work of Reinke influenced Carl Jung.

John Scott Haldane adopted an anti-mechanist approach to biology and an idealist philosophy early on in his career. Haldane saw his work as a vindication of his belief that teleology was an essential concept in biology. His views became widely known with his first book Mechanism, life and personality in 1913. Haldane borrowed arguments from the vitalists to use against mechanism; however, he was not a vitalist. Haldane treated the organism as fundamental to biology: "we perceive the organism as a self-regulating entity", "every effort to analyze it into components that can be reduced to a mechanical explanation violates this central experience". The work of Haldane was an influence on organicism

Haldane also stated that a purely mechanist interpretation can not account for the characteristics of life. Haldane wrote a number of books in which he attempted to show the invalidity of both vitalism and mechanist approaches to science. Haldane explained:
We must find a different theoretical basis of biology, based on the observation that all the phenomena concerned tend towards being so coordinated that they express what is normal for an adult organism.

By 1931, biologists had "almost unanimously abandoned vitalism as an acknowledged belief."

Emergentism

Some aspects of contemporary science make reference to emergent processes; those in which the properties of a system cannot be fully described in terms of the properties of the constituents. This may be because the properties of the constituents are not fully understood, or because the interactions between the individual constituents are also important for the behavior of the system. 

Whether emergence should be grouped with traditional vitalist concepts is a matter of semantic controversy. According to Emmeche et al. (1997):
On the one hand, many scientists and philosophers regard emergence as having only a pseudo-scientific status. On the other hand, new developments in physics, biology, psychology, and cross-disciplinary fields such as cognitive science, artificial life, and the study of non-linear dynamical systems have focused strongly on the high level 'collective behaviour' of complex systems, which is often said to be truly emergent, and the term is increasingly used to characterize such systems.
Emmeche et al. (1998) state that "there is a very important difference between the vitalists and the emergentists: the vitalist's creative forces were relevant only in organic substances, not in inorganic matter. Emergence hence is creation of new properties regardless of the substance involved." "The assumption of an extra-physical vitalis (vital force, entelechy, élan vital, etc.), as formulated in most forms (old or new) of vitalism, is usually without any genuine explanatory power. It has served altogether too often as an intellectual tranquilizer or verbal sedative—stifling scientific inquiry rather than encouraging it to proceed in new directions."

Mesmerism

Franz Mesmer proposed the vitalist force of magnétisme animal in animals with breath.
 
A popular vitalist theory of the 18th century was "animal magnetism", in the theories of Franz Mesmer (1734–1815). However, the use of the (conventional) English term animal magnetism to translate Mesmer's magnétisme animal can be misleading for three reasons:
  • Mesmer chose his term to clearly distinguish his variant of magnetic force from those referred to, at that time, as mineral magnetism, cosmic magnetism and planetary magnetism.
  • Mesmer felt that this particular force/power only resided in the bodies of humans and animals.
  • Mesmer chose the word "animal," for its root meaning (from Latin animus="breath") specifically to identify his force as a quality that belonged to all creatures with breath; viz., the animate beings: humans and animals.
Mesmer's ideas became so influential that King Louis XVI of France appointed two commissions to investigate mesmerism; one was led by Joseph-Ignace Guillotin, the other, led by Benjamin Franklin, included Bailly and Lavoisier. The commissioners learned about Mesmeric theory, and saw its patients fall into fits and trances. In Franklin's garden, a patient was led to each of five trees, one of which had been "mesmerized"; he hugged each in turn to receive the "vital fluid," but fainted at the foot of a 'wrong' one. At Lavoisier's house, four normal cups of water were held before a "sensitive" woman; the fourth produced convulsions, but she calmly swallowed the mesmerized contents of a fifth, believing it to be plain water. The commissioners concluded that "the fluid without imagination is powerless, whereas imagination without the fluid can produce the effects of the fluid."

Medical philosophies

Vitalism has a long history in medical philosophies: many traditional healing practices posited that disease results from some imbalance in vital forces. In the Western tradition founded by Hippocrates, these vital forces were associated with the four temperaments and humours; Eastern traditions posited an imbalance or blocking of qi or prana. One example of a similar notion in Africa is the Yoruba concept of ase. Today forms of vitalism continue to exist as philosophical positions or as tenets in some religious traditions.

Complementary and alternative medicine therapies include energy therapies, associated with vitalism, especially biofield therapies such as therapeutic touch, Reiki, external qi, chakra healing and SHEN therapy. In these therapies, the "subtle energy" field of a patient is manipulated by a practitioner. The subtle energy is held to exist beyond the electromagnetic energy produced by the heart and brain. Beverly Rubik describes the biofield as a "complex, dynamic, extremely weak EM field within and around the human body...."

The founder of homeopathy, Samuel Hahnemann, promoted an immaterial, vitalistic view of disease: "...they are solely spirit-like (dynamic) derangements of the spirit-like power (the vital principle) that animates the human body." The view of disease as a dynamic disturbance of the immaterial and dynamic vital force is taught in many homeopathic colleges and constitutes a fundamental principle for many contemporary practising homeopaths.

Criticism

The 17th century French playwright Molière mocked vitalism in his 1673 play Le Malade imaginaire.

Vitalism has sometimes been criticized as begging the question by inventing a name. Molière had famously parodied this fallacy in Le Malade imaginaire, where a quack "answers" the question of "Why does opium cause sleep?" with "Because of its dormitive virtue (i.e., soporific power)." Thomas Henry Huxley compared vitalism to stating that water is the way it is because of its "aquosity". His grandson Julian Huxley in 1926 compared "vital force" or élan vital to explaining a railroad locomotive's operation by its élan locomotif ("locomotive force").

Another criticism is that vitalists have failed to rule out mechanistic explanations. This is rather obvious in retrospect for organic chemistry and developmental biology, but the criticism goes back at least a century. In 1912, Jacques Loeb published The Mechanistic Conception of Life, in which he described experiments on how a sea urchin could have a pin for its father, as Bertrand Russell put it (Religion and Science). He offered this challenge:
"... we must either succeed in producing living matter artificially, or we must find the reasons why this is impossible." (pp. 5–6)
Loeb addressed vitalism more explicitly:
"It is, therefore, unwarranted to continue the statement that in addition to the acceleration of oxidations the beginning of individual life is determined by the entrance of a metaphysical "life principle" into the egg; and that death is determined, aside from the cessation of oxidations, by the departure of this "principle" from the body. In the case of the evaporation of water we are satisfied with the explanation given by the kinetic theory of gases and do not demand that to repeat a well-known jest of Huxley the disappearance of the "aquosity" be also taken into consideration." (pp. 14–15)
Bechtel states that vitalism "is often viewed as unfalsifiable, and therefore a pernicious metaphysical doctrine."[1] For many scientists, "vitalist" theories were unsatisfactory "holding positions" on the pathway to mechanistic understanding. In 1967, Francis Crick, the co-discoverer of the structure of DNA, stated "And so to those of you who may be vitalists I would make this prophecy: what everyone believed yesterday, and you believe today, only cranks will believe tomorrow."

While many vitalistic theories have in fact been falsified, notably Mesmerism, the pseudoscientific retention of untested and untestable theories continues to this day. Alan Sokal published an analysis of the wide acceptance among professional nurses of "scientific theories" of spiritual healing. (Pseudoscience and Postmodernism: Antagonists or Fellow-Travelers?). Use of a technique called therapeutic touch was especially reviewed by Sokal, who concluded, "nearly all the pseudoscientific systems to be examined in this essay are based philosophically on vitalism" and added that "Mainstream science has rejected vitalism since at least the 1930s, for a plethora of good reasons that have only become stronger with time."

Joseph C. Keating, Jr. discusses vitalism's past and present roles in chiropractic and calls vitalism "a form of bio-theology." He further explains that:
"Vitalism is that rejected tradition in biology which proposes that life is sustained and explained by an unmeasurable, intelligent force or energy. The supposed effects of vitalism are the manifestations of life itself, which in turn are the basis for inferring the concept in the first place. This circular reasoning offers pseudo-explanation, and may deceive us into believing we have explained some aspect of biology when in fact we have only labeled our ignorance. 'Explaining an unknown (life) with an unknowable (Innate),' suggests chiropractor Joseph Donahue, 'is absurd'."
Keating views vitalism as incompatible with scientific thinking:
"Chiropractors are not unique in recognizing a tendency and capacity for self-repair and auto-regulation of human physiology. But we surely stick out like a sore thumb among professions which claim to be scientifically based by our unrelenting commitment to vitalism. So long as we propound the 'One cause, one cure' rhetoric of Innate, we should expect to be met by ridicule from the wider health science community. Chiropractors can't have it both ways. Our theories cannot be both dogmatically held vitalistic constructs and be scientific at the same time. The purposiveness, consciousness and rigidity of the Palmers' Innate should be rejected."
Keating also mentions Skinner's viewpoint:
"Vitalism has many faces and has sprung up in many areas of scientific inquiry. Psychologist B.F. Skinner, for example, pointed out the irrationality of attributing behavior to mental states and traits. Such 'mental way stations,' he argued, amount to excess theoretical baggage which fails to advance cause-and-effect explanations by substituting an unfathomable psychology of 'mind'."
According to Williams, "[t]oday, vitalism is one of the ideas that form the basis for many pseudoscientific health systems that claim that illnesses are caused by a disturbance or imbalance of the body's vital force." "Vitalists claim to be scientific, but in fact they reject the scientific method with its basic postulates of cause and effect and of provability. They often regard subjective experience to be more valid than objective material reality."

Victor Stenger states that the term "bioenergetics" "is applied in biochemistry to refer to the readily measurable exchanges of energy within organisms, and between organisms and the environment, which occur by normal physical and chemical processes. This is not, however, what the new vitalists have in mind. They imagine the bioenergetic field as a holistic living force that goes beyond reductionist physics and chemistry."

Such a field is sometimes explained as electromagnetic, though some advocates also make confused appeals to quantum physics. Joanne Stefanatos states that "The principles of energy medicine originate in quantum physics." Stenger offers several explanations as to why this line of reasoning may be misplaced. He explains that energy exists in discrete packets called quanta. Energy fields are composed of their component parts and so only exist when quanta are present. Therefore, energy fields are not holistic, but are rather a system of discrete parts that must obey the laws of physics. This also means that energy fields are not instantaneous. These facts of quantum physics place limitations on the infinite, continuous field that is used by some theorists to describe so-called "human energy fields". Stenger continues, explaining that the effects of EM forces have been measured by physicists as accurately as one part in a billion and there is yet to be any evidence that living organisms emit a unique field.

Vitalistic thinking has also been identified in the naive biological theories of children: "Recent experimental results show that a majority of preschoolers tend to choose vitalistic explanations as most plausible. Vitalism, together with other forms of intermediate causality, constitute unique causal devices for naive biology as a core domain of thought."
