== History ==
Vitalism has a long history in ] philosophies: most ] practices posited that disease was the result of some imbalance in the vital energies which distinguish living from non-living matter. In the Western tradition, these vital forces were identified as the ]s; eastern traditions posited similar forces such as ], ], etc. More recently, vitalistic thinking has been identified in the naive biological notions of children <ref>Inagaki K, Hatano G (2004) Vitalistic causality in young children's naive biology. ''Trends Cogn Sci'' 2004 8:356-62 PMID 15335462 </ref>.


===Ancient times===
==Development of vitalism==
The notion that bodily functions are due to a vitalistic principle existing in all living creatures has roots going back at least to ].<ref>Jidenu, Paulin (1996) ''African Philosophy, 2nd Ed.'' Indiana University Press, {{ISBN|0-253-21096-8}}, p.16.</ref> In ], the ] proposed natural explanations ] from ] and ].

Aristotle gestures to the earth, representing his belief in knowledge through empirical observation and experience, whilst Plato points up to the heavens showing his belief in the ultimate truth.]]
The notion that bodily functions are due to a vitalistic principle existing in all living creatures has roots going back to at least 384-322 BC. While vitalist ideas have been commonplace in traditional medicine,<ref> e.g. Zarrilli PB. (1989) Three bodies of practice in a traditional South Indian martial art. ''Soc Sci Med'' 28:1289-309. PMID 2660283,

</ref>, attempts to construct workable scientific models date from the 1600s, when it was argued that matter existed in two radically different forms, observable by their behavior with regard to heat. These two forms of matter were termed ''organic'' and ''inorganic''. Inorganic matter could be melted, but could also be restored to its former condition by removing the heat. Organic compounds "cooked" when heated, transforming into new forms that could not be restored to the original. It was argued that the essential difference between the two forms of matter was the "vital force", present only in organic material.


===Medieval===
At the same time, new discoveries questioned whether "organic material" was a ''type'' of matter or merely the product of the complex interaction of materials. Aided by the invention of the ] in the ], the ] of disease gained momentum and challenged the role of vitalism in Western medicine, and the particular roles of the various organs of the human ] in the maintenance of life became better understood, reducing the need to explain things in terms of vague or mystical "vital forces". Nevertheless, vitalist ideas were still thought necessary by many scientists to explain how organisms maintained life.
In Europe, medieval physics was influenced by the idea of ''pneuma'', helping to shape later ].
The ], developed by ] and ] late in the 17th century held that all flammable materials contain phlogiston, a substance without color, odor, taste, or weight that is liberated in burning. Once burned, the "dephlogisticated" substance was held to be in its "true" form, the calx. This vitalist theory led to the prediction that substances should lose weight after burning; it was eventually disproved by the experimental demonstration that, when combustion took place in a closed, sealed system, no weight was lost or gained.


===Early modern===
In the early 19th century, ], known as one of the "fathers" of modern chemistry, rejected the mystical vitalism of his time, but nevertheless argued that a regulative force must exist within living matter to maintain its functions. The geologist ], considered to be one of the top 1,000 scientists of all time, later developed the theory of ], a form of life-energy that permeated living things; this concept never gained much support despite Reichenbach's prestige.
Vitalists included English anatomist ] (1597–1677) and the Italian doctor ] (1628–1694).<ref name="Charles Birch 1985, pp. 76">{{harvnb|Birch|Cobb|1985|pp=76–78}}</ref> ] (1733–1794) is considered to be the father of ] in ], 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 '']'' (1759), he tried to explain the emergence of the organism by the actions of a ''vis essentialis'' (an organizing, formative force). ] (1788–1869) later developed the theory of ], a form of life-energy that permeates living things.


In the 17th century, modern science responded to ]'s ] and the mechanism of ] 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).<ref name=Ede/>
==Mesmerism==
A popular vitalist theory of the eighteenth century was "animal magnetism", in the theories of ] (1734–1815). Indeed, so popular did Mesmer's ideas become that King ] of France appointed two commissions to investigate ]; one was led by ], the other, led by ], included ] and ]. 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 the 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." This was an important example of the power of reason and controlled experiment to falsify theories.

As worded by ] and ], "the claims of the vitalists came to the fore again" in the 18th century:<ref name="Charles Birch 1985, pp. 76"/> "]'s followers were active as were others, such as the physician genius ] of the Hotel Dieu."<ref name="Charles Birch 1985, pp. 76"/> However, "Bichat moved from the tendency typical of the French vitalistic tradition to progressively free himself from ] in order to combine with hypotheses and theories which accorded to the scientific criteria of physics and chemistry."<ref>{{harvnb|''History and Philosophy of the Life Sciences''|p=238}}</ref> ] recognised "a 'living principle' in addition to mechanics."<ref name="Charles Birch 1985, pp. 76"/>
==Vitalism in the foundations of chemistry==
]s in the early ] continued to erode support for vitalism in the Western ] community. It was a vitalist belief that ]s were only produced by living organisms, as a byproduct of the presence of the vital forces. However, as chemical techniques advanced, ] synthesised ] from inorganic components in 1828 , and subsequently ](1845) synthesized acetic acid from its constituents. According to the conventionally accepted view of the subsequent progress of chemistry, further chemical and anatomical discoveries pushed aside the "vital force" explanation, as more and more life processes came to be described in chemical or physical terms. However, contemporary accounts do not support the claim that vitalism died when Wöhler made urea. ''The Wöhler Myth'', as it was called by historian of science Peter J. Ramberg , originates 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"." <ref></ref>


] 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 '']'' 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,

Some of the greatest scientific minds of the time continued to investigate these vital properties. ], shortly after his famous rebuttal of spontaneous generation, made several experiments that he felt supported the vital concepts of life. Bechtel says about Pasteur "Pasteur, by contrast, fitted fermentation into a more general programme describing special reactions that only occur in living organisms. These are irreducibly vital phenomena. Pasteur demonstrated empirically in 1858 that fermentation only occurs when living cells are present and, further, that cells only carry out fermentation in the absence of oxygen, leading him to describe fermentation as ‘life without air’. Finding no support for claims such as those advanced by Berzelius, Liebig, Traube and other chemists that fermentation resulted from chemical agents or catalysts within cells, Pasteur concluded that fermentation was a "vital action" "

Perhaps more than any other area of science, ] has been rich in vitalist concepts, particularly through the influence of the ideas of ] and ]. Freud was a student of the notable anti-vitalist Herman von Helmhotz, and initially he struggled to express his concepts in strictly neurological terms. However, abandoning this effort, he became famous instead for his theory that behaviour is determined by an unconscious mind, of which the waking mind is unaware. In 1923, in '']'', he developed the concept of "]" as the energy by which the work of the personality is performed.


Between 1833 and 1844, ] wrote a book on ] 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 ] makes each organism an indivisible whole. He claimed that the behaviour of light and sound waves showed that living organisms possessed a life-energy for which physical laws could never fully account.<ref>{{cite web |last1=Otis |first1=Laura |title=Johannes Peter Müller (1801-1858) |url=https://vlp.mpiwg-berlin.mpg.de/pdfgen/essays/enc22.pdf |website=Virtual Laboratory: Essays and Resources on the Experimentalization of Life (Max Planck Institute) |date=October 2004}}</ref>
Although Freud and Jung remain hugely influential figures, psychology subsequently made a determined effort to rid itself of the most mystical of these concepts in an attempt to appear more like the "hard" sciences of chemistry and physics<ref> see Warren HC (1918) Mechanism Versus Vitalism, in the Domain of Psychology ''Phil Rev''27:597-615 and
Elkus SA (1911) Mechanism and Vitalism ''J Phil Psych Sci Meth'' 8: 355-8 for examples of this debate within psychology </ref>. However, concepts for instance of ], or of ], and of motivational states such as ], ], ] and ], remain essentially higher level constructs, with observable correlates, but with no adequate low-level description of underlying mechanisms or processes. Whether such low-level descriptions are either possible or desirable is controversial, but some psychologists believe that further change is needed in psychology to eliminate all concepts which have no defined physico-chemical substrates


] (1822–1895) after his famous rebuttal of ], 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, ], ] and others that fermentation resulted from chemical agents or catalysts within cells, Pasteur concluded that fermentation was a "vital action".<ref name=Bechtel/>
==Vitalism in Developmental Biology==
] (1733-1794) is considered to be the father of epigenetic descriptive embryology. 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, and declared that "All believers in epigenesis are Vitalists." However, even early vitalists were aware that the vital forces that they proposed were to be understood ''metaphorically'', not ''literally''. ], established ] as the model of thought in the life sciences in 1781, with his publication of ''Über den Bildungstrieb and das Zeugungsgeschäfte.'' Blumenbach cut up freshwater polyps and established that the removed parts would regenerate; he inferred the presence of a "formative drive". an organic force, which he called "Bildungstrieb". He pointed out that this, "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."


===20th century===
Vitalism was also important in the thinking of later ] such as ] (1867-1941)
In 1894, Driesch wrote a remarkable theoretical essay entitled ''Analytische Theorie der organischen Entwicklung'' where he declared that
:''Development starts with a few ordered manifoldnesses; but the manifoldnesses create, by interactions, new manifoldnesses, and these are able, by acting back on the original ones, to provoke new differences, and so on. With each new response, a new cause is immediately provided, and a new specific reactivity for further specific responses. We derive a complex structure from a simple one given in the egg.''
This insight, which can now be seen as anticipating modern developmental biology, came from his experiments on ] eggs, in which he observed that if an egg was divided in two, it nevertheless gave rise to a perfect, though small ]. Driesch, already a famous biologist, thus became an avowed vitalist, and in so doing saw his retutation as a biologist ruined. He moved to Heidelberg and became a Professor of Natural Philosophy, seeing his vitalism an extension of Immanual ]'s notion that the organism develops as if it had a purposeful intelligence.


] (1867–1941) interpreted his experiments as showing that life is not run by physicochemical laws.<ref name="DevBio">{{Cite web|url=http://7e.devbio.com/article.php?ch=10&id=110|archiveurl=https://web.archive.org/web/20061031180529/http://7e.devbio.com/article.php?ch=10&id=110|url-status=dead|title=Developmental Biology 8e Online: A Selective History of Induction|archivedate=October 31, 2006}}</ref> His main argument was that when one cuts up an embryo after its first division or two, each part grows into a complete adult.

The founder of ], 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." However, as practised today, homeopathy simply rests on the premise of treating sick persons with extremely diluted agents that - in undiluted doses - are deemed to produce similar symptoms in a healthy individual. Thus modern expressions of homeopathy have largely excluded early vitalistic concepts, though whether they have gained any credibility as a result is debatable (see main article ])


] adopted an anti-mechanist approach to biology and an ] philosophy early on in his career. Haldane saw his work as a vindication of his belief that ] was an essential concept in biology.

==Vitalism; its status in science==
The judgement of whether particular vitalistic concepts are "scientific" or not is a subjective one, but is largely a judgement passed by the winners of a debate after the debate has been resolved: many "vitalistic" theories now abandoned were considered as mainstream scientific theories in their time. The replacement of vitalistic theories can thus be seen as having been a progressive refinement of scientific understanding, as the underlying mechanisms of complex phenomena are at least partly revealed. However the limits to this ] have become apparent in recent years, most strikingly in the Mathematics of ], and in particular from the work of ]. These ideas are best known in the metaphor of the so-called "]", that was first clearly recognised by a ], ], who observed that his deterministic ] model of climate systems was unexpectedly sensitive to initial conditions. This finding was expressed famously (and variously) as implying that the flap of a butterfly's wings in a jungle in South America was enough to "cause" a hurricane on the other side of the world. This insight, that complex non-linear systems can give rise to ''inherently'' unpredictable behavior, seemed to set limits on the ability to "explain" complex behavior by ''any'' deterministic description, by setting limits on the "]" of such systems. Subsequently, the work of ] and Stuart Kaufmann amongst others explored how chaos can be "harnessed", by exploring how organised behaviors can arise in a structured way from complex systems, giving rise to the modern concepts of ] and ].


Whether emergence should be grouped with traditional vitalist concepts is a matter of semantic controversy.{{efn|See;<ref>{{cite web |last1=O’Connor |first1=Timothy |title=Emergent Properties |url=http://plato.stanford.edu/entries/properties-emergent/ |website=The Stanford Encyclopedia of Philosophy |publisher=Metaphysics Research Lab, Stanford University |date=2021}}</ref> briefly, some philosophers see emergentism as midway between traditional spiritual vitalism and mechanistic reductionism; others argue that, structurally, emergentism is equivalent to vitalism.

(1997):
Thus, historically, "vitalist" concepts have often "stood for" things that we do not yet fully understand in reductionist terms; this is particularly true in psychology, where the program for replacing vitalistic concepts has been explicitly and progressively aimed at replacing them with lower level descriptions. However, limits or qualifications to this ambition are now recognised in the concepts associated with emergent behavior.


{{quote|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.|<ref name="Emmeche 1997">Emmeche, C.

==Criticisms of Vitalism==


== Mesmerism ==
Vitalism is often used as a ] epithet :<ref>"Other writers (eg, Peterfreund, 1971) simply use the term vitalism as a pejorative label." in
{{main|Animal magnetism}}
Galatzer-Levy,RM (1976) Psychic Energy, A Historical Perspective ''Ann Psychoanal'' 4:41-61 </ref>, talking of the literal mystical definition of vitalism that "holds that living entities contain some fluid, or a distinctive "spirit", declare their opinion that "vitalism now has no credibility" because it is often viewed as unfalsifiable, and "therefore a pernicious metaphysical doctrine". However, the same authors also published a book which presents "an approach to explanation that appeals to interactions between simple components, rather than assigning functions to individual components", recognizing the "sometimes false assumption that nature is significantly decomposable and hierarchical" <ref>Bechtel W, Richardson, RC. (1992) ''Discovering Complexity: Decomposition and Localization as Strategies in Scientific Research'' Princeton University Press ISBN: 0-691-08762-8</ref>. Thus any judgement on whether vitalism is credible or not depends on exactly what is meant by vitalism.
] proposed the vitalist force of '']'' in animals with breath.]]


A popular vitalist theory of the 18th century was "]", in the theories of ] (1734–1815). However, the use of the (conventional) English term ''animal magnetism'' to translate Mesmer's '''magnétisme animal''' can be misleading for three reasons:
Most of the proponents of avowedly vitalistic theories described in this article were not "fringe" scientists but mainstream scientists of their time; their theories similarly were mostly mainstream theories. Not only were these vitalistic theories falsifiable, many were in fact falsified, notably Mesmerism and the phlogiston theory. It is often considered unscientific to continue to espouse a given theory long after that theory has been falsified or replaced, but in the view of philosopher of science ], it is the fate of most scientific theories to be refuted or replaced, and this is the hallmark of "good" science. Thus vitalism ''per se'' is not unscientific in this sense. The perverse retention of falsified vitalistic theories might be considered unscientific; but this is the case whether the perversely retained theories are vitalistic or not.
* 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 ] of France appointed two commissions to investigate ]; one was led by ], the other, led by ], included ] and ]. The commissioners learned about Mesmeric theory, and saw its patients fall into fits and ]s. 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."<ref>{{cite journal |last1=Best |first1=M. |last2=Neuhauser |first2=D. |last3=Slavin |first3=L. |title=Evaluating Mesmerism, Paris, 1784: the controversy over the blinded placebo controlled trials has not stopped |url= http://qhc.bmjjournals.com/cgi/content/full/12/3/232 |journal=Quality & Safety in Health Care |volume=12 |issue=3 |pages=232–3 |year=2003 |pmid=12792017 |pmc=1743715 |doi=10.1136/qhc.12.3.232}}</ref>
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” (1967:99). However, ], co-founder of the ] once a prominent critic of vitalism, but writing in 2002 after the growth of systems biology and the mathematical development of theories underlying emergent behavior stated:


== Medical philosophies ==
:''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. But all their efforts to find a scientific answer to all the so-called vitalistic phenomena were failures.… rejecting the philosophy of reductionism is not an attack on analysis. No complex system can be understood except through careful analysis. However the interactions of the components must be considered as much as the properties of the isolated components.'' <ref>Mayr E (2002) ''The Walter Arndt Lecture: The Autonomy of Biology'', adapted for the internet, on </ref>

== Criticism ==
] mocked vitalism in his 1673 play '']''.]]

Vitalism has sometimes been criticized as ] by inventing a name. ] had famously parodied this fallacy in '']'', where a quack "answers" the question of "Why does ] cause sleep?" with "Because of its '''dormitive virtue''' (i.e., ] power)."<ref name="fr.wikisource.org">'' Mihi a docto doctore / Demandatur causam et rationem quare / Opium facit dormire. / A quoi respondeo, / Quia est in eo / Vertus dormitiva, / Cujus est natura / Sensus assoupire.'' </ref> ] compared vitalism to stating that water is the way it is because of its "aquosity".<ref name="The Physical Basis of Life">, ''Pall Mall Gazette'', 1869</ref> His grandson ] 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 ] and ], but the criticism goes back at least a century. In 1912, ] published ''The Mechanistic Conception of Life'', in which he described experiments on how a sea urchin could have a pin for its father, as ] 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.&nbsp;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.&nbsp;14–15)

Bechtel states that vitalism "is often viewed as ], and therefore a pernicious metaphysical doctrine."<ref name=Bechtel/> For many scientists, "vitalist" theories were unsatisfactory "holding positions" on the pathway to mechanistic understanding. In 1967, ], the co-discoverer of the structure of ], 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 ] will believe tomorrow."<ref name="Crick">Crick, Francis (1967) ''Of Molecules and Men''; Great Minds Series Prometheus Books 2004, reviewed . Crick's remark is cited and discussed in: Hein H (2004) ''Synthese'' 20:238–253, who describes Crick's remark as "raising spectral red herrings".</ref>

While many vitalistic theories have in fact been falsified, notably Mesmerism, the ] retention of untested and ] theories continues to this day. ] published an analysis of the wide acceptance among professional nurses of "scientific theories" of spiritual healing. (Pseudoscience and Postmodernism: Antagonists or Fellow-Travelers?).<ref name="Sokal"></ref> Use of a technique called ] 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."<ref name="Sokal" />

Joseph C. Keating, Jr.<ref>{{Cite web|url=http://www.ncmic.com/pages/ce/seminars/speakers/keating.htm|archiveurl=https://web.archive.org/web/20060525203939/http://www.ncmic.com/pages/ce/seminars/speakers/keating.htm|url-status=dead|title=Joseph C. Keating, Jr., PhD: Biographical sketch|archivedate=May 25, 2006}}</ref> discusses vitalism's past and present roles in ] and calls vitalism "a form of ]." 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 ] 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'."<ref name="keating_innate">{{citation |title=The Meanings of Innate |author=Keating, Joseph C. |volume=46 |issue=1 |pmc=2505097 |journal=The Journal of the Canadian Chiropractic Association |year=2002 |pages=4–10}}</ref>

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."<ref name="keating_innate" />

Keating also mentions Skinner's viewpoint:

: "Vitalism has many faces and has sprung up in many areas of scientific inquiry. Psychologist ], 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'."<ref name="keating_innate" />

According to Williams, "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."<ref name="Williams" /> "Vitalists claim to be scientific, but in fact they reject the scientific method with its basic postulates of cause and effect and of provability.

Vitalism is a belief that starts from the premise 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", "élan vital" (coined by vitalist Henri Bergson), "vital force", or "vis vitalis", 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. Vitalist biologists such as Johannes Reinke proposed testable hypotheses meant to show inadequacies with mechanistic explanations, but their 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 either as a superseded scientific theory, or as a pseudoscience since the mid-20th century.

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). 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 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

Further information: Alternatives to Darwinism
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.

Jöns Jakob Berzelius, one of the early 19th century founders of modern chemistry, argued that a regulative force must exist within living matter to maintain its functions. Berzelius contended that compounds could be distinguished by whether they required any organisms in their synthesis (organic compounds) or whether they did not (inorganic compounds). 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 claimed that the behaviour 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 stated that a purely mechanist interpretation could 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

Main article: Emergentism

Contemporary science and engineering sometimes describe emergent processes, 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 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.

Mesmerism

Main article: Animal magnetism
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. One example of a similar notion in Africa is the Yoruba concept of ase. In the European tradition founded by Hippocrates, these vital forces were associated with the four temperaments and humours. Multiple Asian traditions posited an imbalance or blocking of qi or prana. Amongst unterritorialized traditions such as religions and arts, forms of vitalism continue to exist as philosophical positions or as memorial tenets.

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." 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, "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 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."

Notes

  1. Stéphane Leduc and D'Arcy Thompson (On Growth and Form) published a series of works that in Evelyn Fox Keller's view took on the task of uprooting the remaining vestiges of vitalism, essentially by showing that the principles of physics and chemistry were enough, by themselves, to account for the growth and development of biological form. On the other hand, Michael Ruse notes that D'Arcy Thompson's avoidance of natural selection had an "odor of spirit forces" about it.
  2. In 1845, Adolph Kolbe succeeded in making acetic acid from inorganic compounds, and in the 1850s, Marcellin Berthelot repeated this feat for numerous organic compounds. In retrospect, Wöhler's work was the beginning of the end of Berzelius's vitalist hypothesis, but only in retrospect, as Ramberg had shown.
  3. See; briefly, some philosophers see emergentism as midway between traditional spiritual vitalism and mechanistic reductionism; others argue that, structurally, emergentism is equivalent to vitalism. See also.

Many alternative approaches to modern medicine are rooted in vitalism. ... The exact nature of the vital force was debated by early philosophers, but vitalism in one form or another remained the preferred thinking behind most science and medicine until 1828.
