Vitalism

Summary

Vitalism is the view that living organisms possess a principle or force that cannot be reduced to chemistry and physics alone. In medicine, this conviction shaped how physicians understood disease, healing, and the body for over two thousand years. The Hippocratic writers observed that most patients recover without intervention and concluded that the body works toward its own restoration; Galen systematized this into a theory of innate “natural faculties”; and early modern figures like Paracelsus and Georg Ernst Stahl gave it new forms. Mechanist critics from Asclepiades to Robert Boyle repeatedly declared vitalism obsolete, yet the concept returned under new names in each century. By the mid-nineteenth century the explicit doctrine was largely abandoned by academic medicine, then re-entered philosophy of biology through thinkers like Canguilhem, who reframed it as a question about the nature of norms in living systems.

Ancient Foundations

The Hippocratic Corpus gave Western medicine its first systematic formulation of something like vitalism, though the Hippocratic authors did not use the term and would not have recognized modern category labels. What they observed was clinical: most illnesses, followed without interference, ran a predictable course, worsening to a crisis and then either resolving or killing the patient. From that observation they drew a theoretical conclusion. The occurrence of spontaneous healing was established in the Hippocratic collection as a fact for the first time, and the self-help of the organism in morbid disturbances was elevated to an assumption for all medical thinking and rational therapeutic procedures.(Neuburger, 1943)

The Hippocratic framework described disease as both pathos (suffering, damage done to the body) and ponos (work or effort). The symptom picture contained signs of both destruction and defense simultaneously. Fever, for instance, was understood not merely as injury but as the body’s application of increased warmth to cook (pepsis, coction) the morbid humors until they could be expelled through sweat, urine, sputum, or hemorrhage.(Neuburger, 1943) The physician’s proper role followed directly from this analysis: the Hippocratic physician assigned himself the role of a servant of nature (tês physeos hyperetês), watching the natural healing process, supporting it through dietetic regulation, and intervening with more active measures only when natural aid was absent, delayed, or going wrong.(Neuburger, 1943)

This was not a naive optimism about nature’s infallibility. The Hippocratic writers were careful observers who recognized that nature could err, overshoot, or fail entirely. The physician’s skill lay precisely in reading which aspects of a disease’s course were defensive and which were damaging; this distinction would recur at every subsequent turn in the debate.

The first major ancient physician to refuse this framework entirely was Asclepiades of Prusa, a first-century BCE physician working in Rome whose atomist-mechanist philosophy led him to deny the physis as a healing potentiality outright and to characterize it as a fantasy. What the Hippocratics called nature “vainly laboring,” Asclepiades dismissed; Hippocratic expectative therapy (waiting and watching) he called “a meditation on death.”(Neuburger, 1943) The confrontation between Asclepiades and the Hippocratic tradition established the basic polarity of the mechanism-vitalism debate, which would repeat itself in different vocabularies across subsequent centuries.

Galen’s Natural Faculties

Galen of Pergamon, arriving in Rome in 162 CE as an ambitious provincial physician determined to prove the Empiricist and Methodist physicians around him wrong about nearly everything, gave the vitalist strand in ancient medicine its most systematic and durable formulation. His account rested on what he called the natural faculties (phusikai dunameis): every living being, plants as well as animals, was provided by the Creator with four such faculties — attraction, assimilation, excretion, and growth. These were the powers by which the body maintained itself.(Nutton, 2023) Against Erasistratus and Asclepiades, who proposed mechanistic accounts of bodily function, Galen insisted that the organism could not be adequately described without these irreducible capacities.

Galen’s physiology was organized around a tripartite structure: the liver as origin of the venous system governing nutrition, the heart as origin of the arterial system governing vitality, and the brain as origin of the nerves governing sensation and movement — following Plato’s account of the soul against Aristotle and the Stoics.(Nutton, 2023) Each system operated through its own kind of vital substance (pneuma), and the healthy body was one in which these systems functioned in appropriate balance.

Galen’s framework extended to the boundaries of health itself. While many classical writers, including Seneca, classified old age as a disease, Galen disagreed, classing it instead as an intermediate but natural state between full health and disease — a nuanced position that preserved a role for medicine in managing decline without pathologizing the life course.(Jackson (ed.), 2011)

Of the four natural faculties, Galen gave greatest significance to the excretory power (dynamis apokritiké) for healing purposes, because it effected the crisis: the expulsion of the materia peccans (the harmful material) that resolved the disease.(Neuburger, 1943) The physician’s therapeutic task was to support this power, to identify when the body’s crisis-work needed assistance, and to provide that assistance through purging, bleeding, dietary management, and drugs. The physician could not substitute for nature’s work but could make conditions more favorable for it.

Galen’s system was explicitly opposed to the mechanistic models of his rivals. Temkin’s reading in Galenism (1973) makes the structural reason clear: mechanism and Galenism were not merely different theories but different conceptions of what medicine was for. Mechanism attempted to eliminate teleology entirely, meaning the idea that the organism strives toward anything. Galenism, like Aristotelianism before it, understood the organism as striving to live and to maintain its kind, capable of doing so when all its parts played the role that nature assigned them. When seventeenth-century physicists mechanized the world picture, they were doing something destructive to a framework in which this teleological premise was load-bearing.(Temkin, 1973)

Medieval Continuity and the Archeus

Avicenna, working in early eleventh-century Persia with Galen’s corpus as his authoritative source, preserved and extended the framework. He described the relationship between disease and the organism’s response as a duel, with nature and disease fighting for possession of the patient, and acknowledged that in hopeless cases one must still rely on the innate healing power: “For the true healer is man’s own strength and not his doctor, since the doctor merely takes means to establish strength.”(Neuburger, 1943)

Paracelsus, the early sixteenth-century physician and alchemist who publicly burned Galen and Avicenna in Basle, rejected traditional books for the “book of nature,” and imported mineral-chemical preparations into medicine,(Ackerknecht, 1955) paradoxically preserved the core vitalist intuition under a new name. He conceived the archeus, an internal principle or governing intelligence, as the body’s own physician. In wound care, the physician’s only task was protecting the wound so that nature’s balsam could complete its healing. “Man is his own physician,” Paracelsus wrote, grounding a radical attack on professional medicine in an intensified version of the very claim he was otherwise overturning.(Neuburger, 1943)

Jan Baptist van Helmont, writing in the early seventeenth century, elaborated the archeus in more vivid terms: in fever, the “infuriated Archeus” combated foreign material through trembling, vascular contraction, and copious sweat, the body’s governing intelligence roused to fury against an enemy.(Neuburger, 1943) Driesch’s later assessment placed Helmont’s archeus concept firmly within the Aristotelian lineage: the archeus as smith (faber) who bears within himself the image of what he produces was, in Driesch’s reading, essentially the Aristotelian soul repackaged in new terminology but without Aristotle’s philosophical depth — “merely an inferior edition of Aristotle’s teaching about the soul.”(Driesch, 1914) This was vitalism at its most personified, attracting mockery from mechanists and fascination from defenders in equal measure.

The Seventeenth-Century Crisis

The mechanical philosophy, worked out by Descartes, Boyle, and others across the mid-seventeenth century, posed the first systematic philosophical challenge to vitalist medicine. Robert Boyle recognized a metaphysical purposefulness in creation but refused to attribute conscious direction to the body’s processes; he deliberately coined the expression “mechanism” and wished that this word would replace the word “nature” in all future scientific writing.(Neuburger, 1943) For Boyle, recovery from disease depended on the God-ordained mechanism of the body, not on anything deserving the name of a special healing force.

Sylvius (François de le Boë), the iatrochemist, took the attack further. He called the healing power of nature “chimerical,” argued that what physicians named as nature’s work was simply the effect of proper diet, and accused physicians who trusted nature of negligence toward their patients.(Neuburger, 1943) Thomas Sydenham, the most influential English clinician of the same century and known as “the English Hippocrates,” went the opposite direction, making nature the supreme guide in acute disease and defining disease itself as “nothing else than an effort of nature, who, with all her power, is producing the extermination of sickening matter for the patient’s welfare.”(Neuburger, 1943)

The seventeenth century thus produced the sharpest versions of both positions. The mechanist tradition, however, faced a practical problem that Temkin identified with precision: medicine could not rest on the crude physical and chemical knowledge of the period, and eliminating all teleology from the description of the organism actually hindered rather than helped clinical work. Galen and Aristotle had shared the assumption that the organism strives to maintain itself. While this assumption was philosophically embarrassing to the new physics, it remained clinically indispensable.(Temkin, 1973)

The Eighteenth-Century Schools

The eighteenth century produced the most theoretically developed confrontation between vitalism and its alternatives. Neuburger’s survey of the period identifies three chief representatives: Boerhaave, who as a clinician stood nearest to Hippocratism; Friedrich Hoffmann, who placed mechanical theory in the foreground while making concessions to the living-force principle; and Georg Ernst Stahl, whose doctrine is designated as “animism.”(Neuburger, 1943)

Driesch’s History and Theory of Vitalism (1914) adds a conceptual clarification that most historians overlook. Stahl was technically an animist, not a vitalist: his claim was that the conscious rational soul (anima rationalis) governs organic processes directly as their first cause. Vitalism proper, in Driesch’s taxonomy, asserts autonomous vital forces or processes distinct from the conscious soul. The distinction was significant and immediately lost: most subsequent writers who invoked Stahl treated him as a vitalist type rather than engaging his precise doctrine, and Driesch notes skeptically that he doubted “all those who later speak of Stahl have read the Theoria vera.”(Driesch, 1914) Driesch’s assessment of Stahl’s historical achievement was, nonetheless, generous: Stahl provided the first great scientific system of theoretical biology after Aristotle — a logically constructed edifice whose wide influence Driesch attributed more to the grandeur of its conception and Stahl’s professional authority than to the quality of its proofs.(Driesch, 1914) The sharp distinction between animism (soul as directly causal agent) and vitalism (autonomous vital forces distinct from conscious soul) was, as Driesch noted, effectively erased by the Montpellier school; he also observed that Harvey was more cautious and epistemologically sophisticated than Stahl but had less lasting historical influence, precisely because he declined to build the kind of systematic theoretical edifice that commanded wide imitation.(Driesch, 1914) The Montpellier school dissolved the animism-vitalism boundary by substituting a clinically neutral “vital principle” for his soul concept — a substitution that preserved the clinical orientation while abandoning the metaphysical claim.(Driesch, 1914)

Hermann Boerhaave, whose teaching at Leyden made it the world’s medical center and whose pupils founded the Edinburgh and Vienna schools, praised fever as “the most prosperous instrument of the physician by means of which nature accomplishes the most perfect cure of a thousand diseases.” He went further: the physician versed in nature’s ways, when unable to rely on spontaneous fever in chronic disease, should summon it artificially.(Neuburger, 1943) Boerhaave worked within the Hippocratic tradition without asserting a special metaphysical principle; his vitalism was primarily practical.

Stahl’s animism was philosophically explicit and consequentially different. He held that the rational soul (anima) governed the body’s healing processes directly, that disease was the organism’s purposeful combat against invading damage, and that every disease manifestation was primarily a healing endeavor of the soul. Stahl made natural healing the basis, as Neuburger puts it, “from pillar to crown, the keystone of his system,” and he considered it the physician’s task to recognize natural healing endeavors and support them.(Neuburger, 1943) Fever was, in his account, “the conservative motion of the body, averter of losses, conqueror of enemies, supporter and restorer of its own.”(Neuburger, 1943)

Stahl himself acknowledged, however, that the anima saepe aberrat in actionibus suis: “the soul very frequently errs in its actions.”(Neuburger, 1943) This admission significantly complicates the picture Neuburger’s admiring account projects. Purposeful teleological direction of healing that frequently errs is not quite the same concept as Hippocratic physis, which also errs but does not presuppose rational soul-governance. Neuburger’s tendency to minimize this qualification is one of the places where his teleological bias most clearly inflects his historical narrative.(Neuburger, 1943)

Friedrich Hoffmann, Stahl’s contemporary and rival, drew the mechanist line clearly: he would relegate to the realm of hypotheses “the opinion that nature or a soul possessed of reason, forethought, intention, and interior knowledge constitutes the foundation of medicine.”(Neuburger, 1943) Healing events occurred per accidens, through mechanical necessity, not through purposeful governance. Lorenz Heister’s later dissertations against animism sharpened this position into a clinical formula: the physician is “dominus et magister naturae,” comparable to a charioteer who must carefully attend to his horses lest they run contrary to the goal and cause damage.(Neuburger, 1943) The physician’s task was precisely to identify which mechanical reactions were useful and which were damaging, a distinction requiring the same clinical judgment the vitalists demanded, but grounded in physics rather than soul.

Albrecht von Haller, the great experimental physiologist whose distinction between the primary quality of muscle (“irritability”) and nerve (“sensibility”) transformed physiology,(Ackerknecht, 1955) attacked animism on biological grounds. If the soul governed healing, animals without rational souls would not heal spontaneously — yet they do. He added a pointed textual observation: some passages in Hippocrates that attribute so much to nature “do not for the most part belong to the genuine works of the grand old man.”(Neuburger, 1943)

The Montpellier School and French Vitalism

The most theoretically sophisticated eighteenth-century vitalism developed not in Germany but in southern France. Théophile de Bordeu characterized naturisme as a practical therapeutic orientation grounded in a straightforward empirical claim: in ten diseases, at least two-thirds cure themselves naturally. His approach was deliberately anti-speculative, avoiding metaphysical questions about the nature of the living principle in order to keep the practical conclusion clear.(Neuburger, 1943) Pierre Jean Barthez went further theoretically, positing a principe vital (vital principle) distinct from both soul and mechanism: an immaterial principle expressing itself as the powers of motility, sensibility, and what he called the “force de situation fixe” of bodily parts.(Neuburger, 1943)

Wolfe’s analysis of the Montpellier texts clarifies what these physicians were actually doing. When Bordeu, Ménuret, and Fouquet wrote about life, they produced no metaphysically laden vital forces. Wolfe reads their work as an attempt to model organic life without reducing it to mechanical processes or invoking a special substance — functional rather than substantival vitalism.(Wolfe, Charles T., 2010-2015) The central image of this school was the bee-swarm: Bordeu compared the living body to a cluster of bees in which each part is “not quite an animal, but a kind of independent machine which contributes in its way to the general life of the body.”(Wolfe, Charles T., 2010-2015) Ménuret’s Encyclopédie articles described life as a “connection of actions” (liaison d’actions) rather than a vital substance, each part concurring to form a whole that endures only while the parts maintain their proportional relations.(Wolfe, Charles T., 2010-2015) Even Barthez, who initially asserted the existence of an independent vital force in the first edition of his Nouveaux éléments (1778), withdrew the claim in the second edition, adding a chapter on “Skeptical considerations on the nature of the vital principle” in which he insisted on following “an invincible skepticism” regarding the vital principle’s nature.(Wolfe, Charles T., 2010-2015)

The term “vitalism” itself was coined not by these physicians but by Charles-Louis Dumas in the early nineteenth century as an institutional label to assert the unity of Montpellier teaching — a polemical and retrospective construction rather than a self-description.(Wolfe, Charles T., 2010-2015)

Wolff and Blumenbach: the summit of old vitalism

While the Montpellier school represented French clinical vitalism, the most rigorous German articulations came from Caspar Friedrich Wolff and J. F. Blumenbach. Before them, Buffon had proposed an “inner form” (moule interne) that represented the whole as a manifold, directed development, and imparted order to newly assimilated substance: a force he likened in specificity to gravitation, making Buffon’s chief methodological contribution the explicit assertion of the right to posit vital forces alongside mechanical ones without metaphysical embarrassment.(Driesch, 1914) Driesch identified Wolff (1733–1794) as “the clearest and deepest representative of Vitalism since Aristotle,” who stated his position in the sharpest possible terms: “The bodies implied in development are not machines.” Against both preformationism and machine theory, Wolff posited a vis essentialis — a vital force peculiar to living bodies that drives epigenesis and conserves organic form in the mature organism — and distinguished this explicitly from mechanically explicable processes like circulation, which he regarded as “only a small appendage of the animal.”(Driesch, 1914) Wolff’s methodological honesty was equally important: having established the machine theory’s inadequacy, he refused to speculate further on what the vital force was, acknowledging only “the connexion which exists between machine and life.”(Driesch, 1914)

Blumenbach’s contribution was the nisus formativus (formative impulse) — a force peculiar to living bodies that directs morphogenesis, conserves organic form through nutrition, and restores it after mutilation.(Driesch, 1914) His methodological advance over other vitalists was recognizing that the nisus formativus was less a causal explanation than a named regularity — “an effect ever recurring and ever like itself” — comparable in status to gravitational attraction, which is also a name for a constant observed effect rather than a mechanistic explanation of an underlying cause.(Driesch, 1914) Driesch credited Blumenbach as the first to articulate the concept of “primary purposiveness” — the argument that healing and regenerative phenomena cannot have been preformed because their specific form depends on unpredictable accidents — and as prior both to Wilhelm Roux and to Driesch himself in establishing the distinction between restitution (rebuilding after disturbance) and true regulation.(Driesch, 1914) Driesch’s conclusion was pointed: had all subsequent vitalists maintained Blumenbach’s “essential methodological principle” — treating vital processes as subject to absolutely rigid natural law — the later attacks of Lotze and Bernard would have had nothing to target.(Driesch, 1914)

The transition from Harvey and Stahl to Wolff and Blumenbach marks, in Driesch’s account, the transformation of theoretical biology from a philosophical appendage borrowing ready-made principles from existing dogmas into an independent science — with Wolff and Blumenbach as the only theorists who genuinely surpassed Aristotle.(Driesch, 1914)

The Montpellier school established the pattern that would characterize French vitalism into the nineteenth century: a strong empirical commitment to the therapeutic implications of natural healing, combined with varying degrees of willingness to assert a special vital principle as the philosophical foundation. Philippe Pinel, carrying Hippocratism from Montpellier to Paris, praised Stahl as having produced the most penetrating grasp of Hippocratic doctrine, while insisting that the physician must distinguish beneficial natural reactions from non-beneficial ones.(Neuburger, 1943)

Mesmer and Animal Magnetism

The most popular eighteenth-century expression of vitalist medicine took a form that academic physicians found scandalous. Franz Anton Mesmer, a Viennese physician, settled in Paris in 1781 offering a specialized therapy designed to redirect the flow of animal magnetism — the vital form of the universal magnetic fluid — through the body, removing blockages and restoring health. His practice became fashionable among the Parisian elite and attracted enormous public attention, but it lacked institutional medical support and was condemned by a royal commission in 1784 that included Benjamin Franklin and Lavoisier. Mesmer’s framework nonetheless illustrates how the vitalist premise — that a vital fluid or force circulates through the body and its disruption produces disease — could be translated into a therapeutic program quite different from the regimen-based approaches of the university physicians.(Jackson (ed.), 2011)

William Cullen’s Contradiction

William Cullen, the Scottish physician and nosologist, argued that the “much-vaunted Hippocratic method” had had a baneful influence on practice by producing weak and feeble treatment, mounting what seemed a principled rejection of the vis medicatrix naturae.(Neuburger, 1943) Yet when he presented his own theory of fever, he could not depart from it. He attributed the initial cold stage of fever to the organism’s healing reaction and considered the increased arterial action of the hot stage “to be considered as an effort of the vis medicatrix naturae.”(Neuburger, 1943) The concept had become so structurally embedded in the analysis of fever that even its programmatic opponents could not dislodge it.

John Brown’s Brunonianism was the most radical denial of the period: physicians must always employ a definite plan, always stimulate or weaken, never be inactive, never trust in the powers of nature.(Neuburger, 1943) Even Brown, however, was forced to acknowledge in his discussion of local diseases “a certain force of nature” that strives for cure, and then immediately called it the healing power, the term he had just declared inadmissible.(Neuburger, 1943) These internal contradictions reveal something important about the concept’s structure: it was not primarily a metaphysical commitment but a clinical observation that kept reasserting itself regardless of the theoretical framework physicians adopted.

The Nineteenth-Century Reckoning

In nineteenth-century Germany, ideas on ageing were organized within a broadly vitalist framework that made the “natural ebbing of the life-force” the central explanatory concept for decline, placing the medical study of old age within a general framework of knowledge about the life course. This contrasted with Galenic models that still prevailed in other parts of Western Europe, where old age was analyzed through humoral balance rather than the language of vital force exhaustion.(Jackson (ed.), 2011)

The early nineteenth century produced the most systematic philosophical demolition of vitalist medicine in the German tradition. Jakob Henle’s Pathologische Untersuchungen (1840) argued that healing occurs not through a purposeful defensive autocracy but through the organism’s formative power reverting to normal conditions when external disturbances cease, a mechanical restitution without teleology.(Neuburger, 1943) Henle gave his critique a memorable satirical form: the therapeutic autocracy was “the angel of medicine” fighting “the devil disease,” but the angel was “awkward and blunders, at one time sleeping at the correct moment, now doing too little, now too much, now clawing about the body which it is supposed to defend.”(Neuburger, 1943)

Christoph Wilhelm Hufeland’s earlier synthesis had attempted to dissolve the metaphysical debate from the vitalist side by identifying the healing power of nature with the vital force itself: “The healing power of nature is therefore no special power, but the living power itself employed for a particular object.”(Neuburger, 1943) Johann Christian Reil reached an opposing conclusion from a similar premise: the body’s forces follow necessary laws that may produce either recovery or death, and healing via the organism’s reaction is accidental, not teleologically directed.(Neuburger, 1943)

Rudolf Hermann Lotze offered the mechanist resolution that proved most intellectually durable: the healing power of nature is “not an affective power merely appearing in the moment of danger but the beautiful resultant of the most artificial and wisest mechanism,” a system so well arranged that external disturbances automatically trigger pre-arranged mechanical sequences leading to restoration.(Neuburger, 1943) Carl Wunderlich, founder of “physiologic medicine,” supported this position from a clinical direction: expectative therapy was practically justified (most curable diseases pass into cure without help), but the concept of “a special choosing will” in the organism should be rejected; what appears as purposive healing is the manifestation of a “general developmental law.”(Neuburger, 1943)

The Second Vienna School conducted the most consequential empirical test. Under Josef Skoda, comparative studies on pneumonia with and without venesection demonstrated that omitting the standard intervention produced equal or better outcomes. The Vienna school concluded that in most cases they should intervene only on vital indications and otherwise create favorable conditions for undisturbed natural healing processes.(Neuburger, 1943) Joseph Dietl drew the principle: “Only nature can heal — this is the highest principle of practical medicine.”(Neuburger, 1943)

A striking argument came from an unexpected direction: homeopathy. Contemporary observers pointed out that if homeopathic doses were pharmacologically inert yet produced cure rates comparable to standard medicine, then the curative agent in homeopathic treatment must be the organism’s own healing power. As one commentator put it: if the medicinal healing influence in homeopathy equals nothing, then the curative effect appearing must be simply that of nature alone.(Neuburger, 1943) This was not an endorsement of homeopathy but a back-handed empirical argument for spontaneous healing capacity.

Neuburger himself framed the mid-nineteenth century as a boundary: “The doctrine of the healing power of nature proved itself in the midst of destructive systems of medicine a true rocher de bronze. It outlasted the old humoral pathology and, what is especially significant, it was not included in the crash of vitalism. As this was suppressed in physiology, it radiated in a new light.”(Neuburger, 1943) His “rocher de bronze” formulation overstates the doctrine’s philosophical survival. By mid-century virtually every leading German academic figure had rejected the idea of a special teleological healing force in favor of mechanistic or developmental-law accounts. But Neuburger accurately identifies that the clinical observation motivating the concept survived and flourished in a new institutional form.

Driesch on vitalism’s defeat: self-extinction, not refutation

Driesch’s History and Theory of Vitalism (1914) offers a different and historically sharper account of why old vitalism collapsed. The work presents, as Driesch himself put it, a “deductive vitalism” — descending from logical possibility to empirical fact, the reverse of his earlier inductive Gifford Lectures — and defines nature as the one mediate object that obeys the postulates of a rational theory of becoming.(Driesch, 1914) In its historical portion, the survey is less concerned with biographical detail than with identifying what is “typical” in each vitalist or anti-vitalist position; Driesch also explicitly acknowledges that biology’s history does not show the same logical progression as physics, because biology depends on empirical discovery rather than a priori reasoning.(Driesch, 1914) The critics who appeared to demolish vitalism — primarily Lotze (1842) and Claude Bernard — were, in Driesch’s reading, mostly attacking exaggerated or poorly stated versions rather than the careful formulations of Wolff and Blumenbach.(Driesch, 1914) Lotze’s main charge — that the formative impulse “can never explain anything, as here the law is lacking” — was grounded in a demand for quantitative law that the subject matter could not supply; his own soul-theory, however, admitted unconscious purposiveness and an “absolutely new beginning for mechanical movement” that brought him “extraordinarily near” to the vitalism he had rejected.(Driesch, 1914) Bernard’s critique attacked a straw man (primarily Bichat’s version) while his own positive commitment — that physico-chemical conditions cannot by themselves “group, harmonise phenomena in the order they affect in living beings” — was, Driesch argued, effectively a vitalist claim.(Driesch, 1914) More precisely, Bernard’s most important positive contribution was his phenomenalistic critique of “force” as metaphysical: every science, he argued, knows only the conditions under which phenomena manifest themselves, making the vital force as a force always a metaphysical construction — a view Driesch identified as making Bernard implicitly a “critical Vitalist.”(Driesch, 1914) His final verdict: Bernard was “a true Vitalist, who is only to be charged with inconsistency in relation to his choice of many expressions.”(Driesch, 1914)

The old vitalism died, in Driesch’s account, not because it was refuted but because it ceased to justify itself — stopped producing new proofs and lost the capacity to face attack: “Vitalism had not been overthrown; it had only been purified.”(Driesch, 1914) Neovitalism, as Driesch later defined it, was not wholly new: its novelty lay in its method, which was connected to eighteenth-century vitalist procedure rather than to the nineteenth-century theories that had replaced it, and it returned to foundations in order to prove the vitalistic view of life necessarily true.(Driesch, 1914) The materialistic-Darwinian period that followed was reinforced by four converging pressures: the rise of explicit materialist metaphysics (Moleschott, Vogt, Büchner), Darwinism’s explanation of purposive organisation as accidental, the discovery of the law of conservation of energy, and improved microscopic investigation of living structures.(Driesch, 1914) The combination made mechanistic dogmatism seem self-evidently correct to a generation of biologists who had not thought carefully about the empirical arguments for vital autonomy.

The Repeated Pattern

What the evidence from Neuburger’s survey reveals, read against his own teleological framing, is a pattern more interesting than a simple story of vitalism’s survival or defeat. Physicians who rejected the vis medicatrix naturae as a metaphysical principle kept reintroducing something functionally equivalent when they confronted actual clinical phenomena: fever, crisis, spontaneous recovery, wound healing, tuberculosis regression. Asclepiades dismissed the Hippocratic physis as fantasy, then said nothing systematic about how patients recovered. Cullen attacked the concept programmatically, then used it to explain the stages of fever. Brown denied it in principle, then acknowledged “a certain force of nature” in local disease. The concept kept returning not because physicians were philosophically careless but because the clinical phenomena it described were real and poorly captured by the available mechanistic alternatives.

Ackerknecht observed that many patients in contemporary practice still hold medical beliefs traceable to ancient Greek, Paracelsian, or Brunonian frameworks, a persistence he attributed to the power of old theories over popular imagination.(Ackerknecht, 1955) The same observation applies, with different force, within professional medicine: vitalism persisted there not merely as popular belief but because the clinical observations it tracked did not disappear when the theoretical vocabulary was condemned.

Neovitalism: Driesch, Bergson, and the Twentieth-Century Revival

The nineteenth century’s apparent defeat of vitalism proved premature. During the materialist-Darwinian ascendancy, a vitalist tradition persisted mainly among opponents of orthodox Darwinism — Karl Ernst von Baer, Wilhelm His, and the philosopher Eduard von Hartmann, who was the first to make “finality” a pure category alongside substance and causality, rather than treating it merely as a regulative principle in Kant’s sense.(Driesch, 1914) Their efforts kept the principle of vital autonomy alive until experimental morphology gave it new empirical ground.

Two thinkers gave the concept new life in the early twentieth century, though in fundamentally different registers.

Hans Driesch, an experimental embryologist who became a philosopher, produced the most rigorous modern defense of vitalism through laboratory evidence rather than speculation. Driesch traced the intellectual genealogy of vitalism to Aristotle, whom he identified as the first scientific vitalist: Aristotle took embryology — the problem of formation from the germ — as his primary biological starting point, a pattern that Driesch argued is replicated by all subsequent vitalist theories.(Driesch, 1914) Aristotle’s theory qualified, in Driesch’s taxonomy, as “pure Vitalism” and “primitive or naive Vitalism,” meaning it arose from impartial observation of life rather than as a polemical response to rival doctrines — a contrast with later forms of vitalism shaped by the struggle with mechanism.(Driesch, 1914) Aristotle remained the authoritative source in biological and bio-theoretical questions from antiquity through the mid-eighteenth century; Driesch argued that Aristotle’s core assertions about vital autonomy were ultimately vindicated by late-nineteenth-century experimental biology.(Driesch, 1914) The distinction between static and dynamic teleology — the key diagnostic tool Driesch applied throughout his survey — turned on whether organic purposiveness is similarly structure-dependent to a machine’s or reflects a deeper autonomous law.(Driesch, 1914) His key demonstration involved sea-urchin embryos: remove up to three-quarters of the cells from a blastula, and the remainder still develops into a complete, though smaller, organism — what Driesch called a harmonious-equipotential system.(Driesch, 1914) From this and related experiments Driesch drew a philosophical conclusion. A machine cannot remain itself after arbitrary parts are removed; therefore the embryo is not a machine; therefore some non-mechanical agent governs its development. His second proof extended this argument to inheritance: if each egg cell is capable of forming the whole organism, and this capacity is preserved through innumerable cell divisions, no machine differentially built up in three spatial dimensions could survive such division and remain what it was — therefore inheritance cannot depend on mechanical factors exclusively.(Driesch, 1914) His third proof moved to human action: genuine action involves an “individual correspondence” between organism and stimulus, on an historically created basis of prior possibilities, that cannot be expressed as a mechanical sum-to-sum correspondence.(Driesch, 1914)

He called the agent responsible for these phenomena entelechy — borrowing Aristotle’s term but giving it a precise modern definition: a non-material, non-spatial agent that acts into space by controlling which preformed material possibilities become actual, without itself creating or consuming energy.(Driesch, 1914) Driesch was careful about what entelechy does and does not do: it does not create energy, it does not violate energy conservation; it only determines which of the physically possible events occurs at each moment. Beyond these “proofs,” he also identified a class of indicia — facts pointing toward vital autonomy without strictly proving it — including equifinality (the same regulatory result reached by different developmental paths), active adaptation, and immune response.(Driesch, 1914)

Driesch’s framework rested on a careful taxonomy of teleology. He distinguished descriptive teleology (merely acknowledging purposiveness), static teleology (purposiveness grounded in mechanical structure, as in a machine), and dynamic teleology (purposiveness arising from autonomous vital processes). Only the third, he argued, constituted genuine vitalism — the claim that the organism’s purposiveness cannot be explained by any arrangement of already-known physical factors.(Driesch, 1914) The fundamental question of vitalism, he maintained, was not whether life exhibits purposiveness but whether that purposiveness arises from a special constellation of already-known physical factors or from an autonomous principle peculiar to vital processes.(Driesch, 1914) This tripartite taxonomy was also a critical diagnostic tool: many historical figures who appeared to be vitalists were actually proposing static teleology, while others who denied vitalism nonetheless relied on dynamic teleological reasoning when they confronted embryological or regenerative phenomena.(Driesch, 1914)

Driesch described his own intellectual trajectory as moving from static (machine) teleology in 1893–94 to full dynamic vitalism by 1895–99, triggered by the sea-urchin experiments. His 1899 paper Die Lokalisation morphogenetischer Vorgänge was, he claimed, “the first work in which it is clearly demonstrated that certain at least of the processes of life can only be understood as autonomous, obeying only their own laws.”(Driesch, 1914) His deductive presentation of vitalism in the 1914 History and Theory descends from logical possibility — distinguishing four types of causality — to empirical fact, the reverse of his earlier inductive approach. The fourth type of causality, which he called “individualising” or “unifying” causality, is the kind that increases relational manifoldness in a system without any spatial agency being responsible — which he identified as the hallmark of vital becoming.(Driesch, 1914)

Driesch’s entelechy was precisely the kind of claim that made vitalism vulnerable to scientific attack. The Vienna Circle singled it out as paradigmatic metaphysical nonsense. Wolfe argues that this condemnation was philosophically justified against Driesch’s substantival vitalism specifically, but that the wholesale rejection of vitalism that followed confused one problematic species of the doctrine with the entire genus.(Wolfe, Charles T., 2010-2015)

Bergson, who worked contemporaneously, is treated by Driesch somewhat dismissively — as confirming conclusions already reached rather than advancing essentially new arguments, alongside Gurwitsch’s work on determination and heredity.(Driesch, 1914) Their rivalry is historically significant: they are the two principal early twentieth-century vitalists, but Driesch’s approach was through formal argument and embryological proof while Bergson’s proceeded from the philosophy of time and consciousness.

Henri Bergson’s Creative Evolution (1911) approached the question from a different direction entirely. Where Driesch argued from embryological evidence to a special causal agent, Bergson argued from the nature of time itself. Consciousness, he held, is constituted by duration — a continuous, irreversible flow in which the whole past survives and acts on the present, not a succession of discrete states.(Bergson, 1911) For a conscious being, to exist is to change, to change is to mature, and to mature is to create oneself endlessly.(Bergson, 1911) Inorganic matter, by contrast, has no history: its present state contains nothing more than its past, and it can in principle return to earlier states.(Bergson, 1911) Bergson’s élan vital was not a force in the physicist’s sense but the name for this irreducible creative dimension of life — the fact that living systems generate genuine novelty rather than merely rearranging existing elements.

Bergson’s vitalism was more philosophically subtle than Driesch’s but also harder to test, and scientists largely dismissed it as literary philosophy. Its influence ran instead through continental philosophy, where it shaped Canguilhem’s thinking about normativity and life.

Wolfe’s Taxonomy: Three Species of Vitalism

The historiography of vitalism suffered for most of the twentieth century from the assumption that there was one thing called “vitalism” — that Stahl, Bordeu, Driesch, and Canguilhem were all defending the same claim and that this claim had been refuted. Charles Wolfe, working from the Montpellier archives and the French philosophical tradition, has proposed a taxonomy that dissolves this confusion.

Wolfe distinguishes three species. Substantival vitalism posits the existence of a vital force or substance that plays a causal role in the natural world — Stahl’s animism and Driesch’s entelechy are paradigm cases.(Wolfe, Charles T., 2010-2015) Functional vitalism operates post facto, from the observed existence of living bodies to the search for explanatory models that do justice to their distinctively vital properties without either reducing them to mechanism or invoking a special substance — the Montpellier physicians exemplify this approach.(Wolfe, Charles T., 2010-2015) Attitudinal vitalism treats vitalism not as a theory about the world but as an epistemic stance, a way of approaching biological questions — Canguilhem’s position, which Wolfe characterizes as an exigence (a demand or requirement) rather than a doctrine.(Wolfe, Charles T., 2010-2015)

The taxonomy matters because the standard refutation of vitalism — that no vital force has been found, that biochemistry explains life processes mechanistically — applies only to the substantival species. Functional vitalism makes no claims about special forces; it claims only that mechanistic models fail to capture what is distinctive about organisms. Attitudinal vitalism makes no empirical claims at all; it holds that biology requires a different kind of attention than physics, that the question “what is it to be alive?” cannot be dissolved by chemical analysis.(Wolfe, Charles T., 2010-2015)

Wolfe further argues that vitalism and materialism are not the simple opposites they are usually taken to be. Several eighteenth-century thinkers — Diderot, La Mettrie, Toland — developed what Wolfe calls vital materialism: a conception of matter itself as active, dynamic, and possessed of irreducibly vital properties like irritability and sensibility.(Wolfe, Charles T., 2010-2015) This tradition insisted on the materiality of living systems while refusing to reduce that materiality to the passive, mechanical matter of Cartesian physics. The opposition between vitalism and materialism, on this reading, is an artifact of treating Cartesian mechanism as the only possible materialism.(Wolfe, Charles T., 2010-2015)

The Vitalismus-Problem itself, Wolfe argues, is a specifically post-Cartesian problem. It was the mechanical philosophy’s insistence on inert, passive matter that created the need for a special vital principle in the first place. Ancient and medieval thinkers who attributed active powers to physis or the archeus were not addressing the same philosophical problem because they did not begin from a conception of matter stripped of all active qualities.(Wolfe, Charles T., 2010-2015)

Canguilhem and the Transformation of the Debate

The most far-reaching twentieth-century reconfiguration of vitalism as a philosophical concept came from Georges Canguilhem, the French philosopher and physician whose work transformed the terms in which health and disease could be discussed. Where nineteenth-century debates asked whether living organisms possess a special vital force irreducible to physics, Canguilhem shifted the question to the normative dimension of biological life. In his account, health is flexibility: the healthy organism can tolerate environmental impacts, adapt to new situations, and possesses “a store of energy and audacity” that cannot be reduced to physiological measurement.(Dominic Murphy, 2020)

Canguilhem laid out his position most fully in the “Aspects of Vitalism” chapter of La connaissance de la vie (1952; English translation Knowledge of Life, 2008). He began from a disarming observation: the fact that biologists still feel the need to refute vitalism proves either that the concept has a vitality of its own — unlike phlogiston or geocentrism, which no one bothers to refute anymore — or that engaging with vitalism has forced its critics to sharpen their arguments in ways that produced genuine scientific gains.(Canguilhem, Georges, 1952/2008) Either way, vitalism demands philosophical explanation rather than dismissal.

Canguilhem read the history of biological theory as permanently oscillating between mechanism and vitalism, preformation and epigenesis, atomicity and totality. This oscillation, he argued, is not a mark of biology’s immaturity compared to physics. It may instead express an undiscovered dialectic — a productive tension in which each position revitalizes the other.(Canguilhem, Georges, 1952/2008) He supported this reading with specific historical examples: vitalists had made authentic contributions to science, including Wolff’s founding of modern embryology, von Baer’s discovery of the mammalian egg, and Willis and Pfluger’s development of reflex theory.(Canguilhem, Georges, 1952/2008)

Driesch’s own trajectory illustrates a principle Canguilhem considered significant: Driesch’s experiments on sea-urchin blastomere totipotence led him to vitalism only after he had begun the research intending to confirm mechanistic Entwicklungsmechanik; vitalism was a conclusion forced by experimental evidence, not a starting prejudice (Canguilhem, Georges, 1952/2008). Canguilhem also offered a broader characterization of the vitalist disposition: a scientist who feels a filial sentiment toward nature, finding life, soul, and meaning in natural phenomena, is fundamentally a vitalist, in contrast to one who holds nature as a foreign object to be mastered (Canguilhem, Georges, 1952/2008).

Canguilhem was not naive about vitalism’s philosophical weaknesses. He acknowledged that the verbal concepts of classical vitalism — vital principle, vital force, entelechy — were justly criticized as question-begging even by sympathetic thinkers.(Canguilhem, Georges, 1952/2008) And he recognized that Driesch’s entelechy had been politically exploited by Nazi ideology, though he dismissed this as irrelevant to the concept’s philosophical merit, just as Darwinism’s exploitation for imperialism does not discredit biology.(Canguilhem, Georges, 1952/2008)

His own diagnosis of classical vitalism’s error was precise: it suffered from “excessive modesty.” By accepting that the living exists within a physical milieu and merely demarcating enclaves of indetermination within it, classical vitalists conceded too much to the mechanist framing.(Canguilhem, Georges, 1952/2008) The deeper move, Canguilhem argued, is to recognize that once life’s originality is granted, it is matter that must be comprehended within life and the science of matter within the activity of the living — not life as a province within the territory of matter.(Canguilhem, Georges, 1952/2008)

What vitalism expresses, in Canguilhem’s account, is a permanent exigence — a demand of life within the living for recognition of its own specificity. Vitalism translates this self-identity of life immanent to the living, which is why it is characteristically vague where mechanism is precise: mechanism is a method, vitalism is a demand.(Canguilhem, Georges, 1952/2008) This is also why vitalism and medical naturalism are indissociable. Medical vitalism expresses a fundamental distrust of the power of technique over life, rooted in the Hippocratic confidence in natura medicatrix.(Canguilhem, Georges, 1952/2008) The successive rebirths of vitalism translate, in discontinuous fashion, life’s permanent distrust of its own mechanization.(Canguilhem, Georges, 1952/2008)

Canguilhem’s closing formulation captures the whole position: “to do justice to vitalism is simply to give life back to it.”(Canguilhem, Georges, 1952/2008)

Foucault, in his 1978 introduction to On the Normal and the Pathological, summarized this attitudinal vitalism in a sentence Canguilhem himself had written and Foucault then quoted approvingly: vitalism is “a demand rather than a method, a morality more than a theory.”(Canguilhem, 1978) Foucault’s gloss treated vitalism as a double indicator: theoretical, in that it marks unsolved problems about the originality of life; and critical, in that it warns against reductions that ignore the value-positions (preservation, regulation, adaptation) the life sciences must maintain in any reckoning with their object.(Canguilhem, 1978)

The biological consequence Canguilhem drew from this stance is conservative in one respect and radical in another. Conservatively, medicine remains an activity rooted in the living being’s spontaneous effort to dominate its environment and organize it according to its own values, and it uses the results of all sciences in service of the norms of life — without itself being one of the sciences.(Canguilhem, 1978) Radically, Canguilhem proposed in the 1966 Foreword that there is no a priori ontological difference between a successful living form and an unsuccessful one. The very notion of an “unsuccessful” form depends on a determination of the obligations a living being has, which biology cannot supply on its own.(Canguilhem, 1978) This dissolves the substantival vitalism that would treat life as a unitary metaphysical principle while preserving the attitudinal demand that life’s specificity not be flattened into chemistry.

Wolfe and Wong’s analysis confirms and extends this reading. Canguilhem began his career as explicitly anti-Bergsonian, critical of Bergson’s speculative excesses, but by his later work he had come to describe himself as a vitalist — though of a very specific kind.(Wolfe, Charles T., 2010-2015) Wolfe characterizes Canguilhem’s position as the exemplar of attitudinal vitalism: not a theory about the world but an epistemic stance, operating as “ethics rather than a theory.”(Wolfe, Charles T., 2010-2015) The French biophilosophical project of the mid-twentieth century — Canguilhem, but also Kurt Goldstein and Raymond Ruyer — blended historical analysis with philosophical inquiry to challenge the assumption that biology is merely applied chemistry.(Wolfe, Charles T., 2010-2015)

Physio-medicalism: An American Practitioner Tradition

Andrew Taylor Still, the founder of osteopathy, stated his vitalist premise in explicitly mechanical terms that concealed a deeper anti-reductionism: “The human body,” he told his students, “is a machine run by the unseen force called life, and that it may be run harmoniously it is necessary that there be liberty of blood, nerves, and arteries from their generating point to their destination” (Gevitz, Norman, 2004). Still rejected bacteriology outright: “I believe but very little of the germ theory,” he once declared, “and care much less” (Gevitz, Norman, 2004). His faculty split on the question. Carl McConnell and J. Martin Littlejohn proposed a reconciliation: germs might be the active cause of disease, but spinal lesions were predisposing causes that lowered bodily resistance, making immunology rather than bacteriology the vindication of Still’s system (Gevitz, Norman, 2004). This move converted Still’s anti-germ stance into a vitalist soil theory compatible with laboratory medicine, a strategy parallel to Lindlahr’s absorption of Bechamp.

Alva Curtis, working in America in the mid-nineteenth century, gave the vitalist conviction its most codified North American practitioner formulation in physio-medicalism. His system rested on a direct doctrinal statement: the human body is formed and maintained in health by an invisible vital force, and all disease consists of obstacles to the free flow of that force.(Stapley, 2024) The therapeutic consequences were equally direct — if the vital force is the agent of health, then no treatment should harm organic tissues or the force itself, which ruled out not only poisonous narcotics but blistering, cupping, and much of the standard heroic medicine of the period.(Stapley, 2024)

In practice, Curtis’s system operated through three strategies working in support of the vital force rather than against it: antispasmodics, most often lobelia, to relax constricted tissue; heating agents — capsicum, ginger, xanthoxyllum, cloves, and pennyroyal — to stimulate tissues toward health; and mucilages for lubrication.(Stapley, 2024) The formula was distinctly different from Eclectic medicine’s more aggressive targeting of disease processes: where Eclectics opposed disease directly, physio-medicalists sought to restore the conditions under which the vital force could do its own work.

Lindlahr’s Nature Cure Vitalism

Henry Lindlahr, the Chicago physician who published Philosophy of Natural Therapeutics in 1918, represents a distinct and more philosophically ambitious strand of American practitioner vitalism than physio-medicalism. Where Curtis grounded his system in a practical therapeutic rule — support the vital force, harm nothing — Lindlahr attempted a systematic philosophical synthesis, integrating Bechamp’s microbiology, Pythagoras’s cosmology, Reichenbach’s electromagnetic physics, and Hippocratic naturism into a single coherent theory of life, disease, and cure. Central to this system was the claim that vital force is the primary energy of life, irreplaceable and finite: it cannot be increased by food, stimulants, or drugs but only conserved or depleted, with the rate of its expenditure determining the length and quality of life.(Lindlahr, Henry, 1918)

Lindlahr’s ontological starting point was vibrational. All things in nature, from a fleeting thought to the hardest piece of diamond, are modes of motion or vibration, and John Newlands’s discovery in 1863 that the elements arranged by atomic weight display the same periodic relations as tones in the musical scale was, for Lindlahr, a modern confirmation of the Pythagorean “music of the spheres.”(Lindlahr, Henry, 1918) From this universal vibrational ontology he derived his definition of health and disease: health is normal and harmonious vibration of the elements and forces composing the human entity on the physical, mental, and moral planes of being, in conformity with the constructive principle in nature; disease is abnormal or inharmonious vibration in conformity with the destructive principle.(Lindlahr, Henry, 1918) This framing aligned his vitalism with a cosmic order rather than merely a clinical heuristic. Disease is disturbed polarity or unbalanced chemical equilibrium — health being what he called “satisfied polarity,” the balancing of positive and negative elements in harmonious vibration.(Lindlahr, Henry, 1918) The Law of Polarity extended from chemistry and physics to psychology: positive emotions produced alkaline metabolic products and constructive vital activity while negative emotions produced acid products and destructive catabolic processes, providing a mechanism by which mental states directly altered the material chemistry of disease.(Lindlahr, Henry, 1918)

Lindlahr’s theory of immunity departed equally from the bacteriological mainstream. Natural immunity, in his account, depends not on antibody titers but on good vitality, clean blood and tissues, active organs of elimination, and a positive fearless attitude of mind.(Lindlahr, Henry, 1918) Heredity is not a primary cause of disease but a secondary effect: parents with good vitality and pure blood produce healthy offspring, while hereditary disease results from parental violation of nature’s laws causing lowered vitality and deteriorated blood and tissues.(Lindlahr, Henry, 1918) The microbiological underpinning for this position came from Bechamp rather than Pasteur. Lindlahr adopted Bechamp’s teaching that cells and germs are composed of still smaller living units called microzyma, whose physical characteristics depend on the soil in which they feed, grow, and multiply — developing into normal cells in healthy tissue and into bacteria in morbid conditions.(Lindlahr, Henry, 1918) Mental and emotional conditions operate at the same level: fear, worry, and anxiety congeal the tissues and contract the minute channels of life, paralyzing vital activities, while constructive emotions of faith, hope, cheerfulness, and love exert a relaxing, harmonizing, and vitalizing influence.(Lindlahr, Henry, 1918) The Vedic teaching that “the whole of the universe is evolved through Sankalpa (thought ideation) alone” was, for Lindlahr, confirmed by his physiology rather than superseded by it.(Lindlahr, Henry, 1918)

The physical expression of the vital force also received cosmological grounding through the septimal law. Pythagoras’s doctrine that seven is the number of manifestation and completion pervades ancient philosophy and appears in seven tones of the musical scale, seven colors of the spectrum, seven planets, and seven days of the week.(Lindlahr, Henry, 1918) Lindlahr applied this law to clinical periodicity: healing crises in chronic disease follow five-week cycles of improvement followed by a crisis week, reproducing the pattern of the critical days that Hippocrates had documented in acute disease at seven-day intervals.

For Lindlahr, magnetic and sympathetic healing operated through a real if currently unmeasurable force. Baron Karl von Reichenbach’s investigations of the odic force demonstrated that a subtle electromagnetic emanation radiates from all living organisms, from magnets, and from crystals, perceptible by sensitive individuals as light, warmth, and sensation.(Lindlahr, Henry, 1918) Sympathy healing — the well-documented phenomenon by which close personal contact with a healthy person benefits the sick — is explicable on this basis: a person with a strong positive vital polarity radiates odic energy that supplements the depleted vital reserves of those in proximity, while a person with a negative vital polarity draws upon the vital reserves of those around them.(Lindlahr, Henry, 1918) The vitalist integrating principle that Lindlahr drew from this extended to all therapeutic systems: wherever a system respects and assists the body’s own healing forces, it is compatible with Nature Cure, which is why both homeopathy and spinal manipulation belong within its framework.(Lindlahr, Henry, 1918) The complete Nature Cure system, in this synthesis, addresses three dimensions simultaneously: physical treatment through hydrotherapy, diet, fasting, and spinal manipulation; mental treatment through auto-suggestion and positive attitudes; and spiritual treatment through faith and alignment with natural law — no single modality being sufficient without the others.(Lindlahr, Henry, 1918) This three-dimensional formulation brought Lindlahr’s vitalism closer to Wolfe’s attitudinal species than to either the substantival vitalism of Stahl or the functional vitalism of the Montpellier school: the vital force was real but the primary claim was epistemological — that healing requires a different kind of attention than mechanical intervention.

The naturist and vitalist medicine of the late nineteenth and twentieth centuries also found a specific cultural use for Hippocrates that went beyond clinical doctrine. Pormann observes that Hippocrates came to be employed to organize a longing for a lost organic world where the doctor was treated with almost religious deference and the healing power of nature had yet to be displaced by modern science and technology.(Pormann (ed.), 2018) Arthur John Brock, the physician who translated Galen’s On the Natural Faculties and worked in the naturist tradition, gave this longing a specific form: he argued that Hippocrates’ organic and vitalistic view of the body and disease represented the medical expression of the sanity, balance, and common sense that had characterized ancient Greek cultural life as a whole. For Brock, Hippocrates saw disease as a process, and the practical problem was to follow its natural course through clinical observation.(Pormann (ed.), 2018) This reading made Hippocrates not merely a historical source but a symbol of the organic world that modernity had lost.

Vitalism in Contemporary Phytotherapy

While academic biology moved toward Canguilhem’s attitudinal reformulation of vitalism, the concept found a different kind of continuation in twentieth-century Western herbalism. David Hoffmann’s Medical Herbalism (2003), one of the most widely used clinical phytotherapy texts in the English-speaking world, makes the connection explicit: most herbalists and naturopaths hold what Hoffmann calls a vitalist worldview, and this shapes how they interpret the pharmacological evidence in front of them.

The clearest expression of this worldview appears in Hoffmann’s treatment of plant secondary metabolites. Orthodox pharmacology tends to read these compounds through a Darwinian defense-mechanism lens, in which plants and the animals that consume them “coexist in an uneasy balance of chemical power.” Hoffmann names this position as “the antithesis of the vitalist worldview held by most herbalists and naturopaths, who would rather see the relationship between ‘plants and those using them’ characterized as coevolutionary mutualism.”(Hoffmann, David, 2003) The disagreement has clinical weight. If plant compounds evolved in a context of competition and toxicity, the practitioner’s task is to find the right dose before harm occurs; if they evolved in a context of mutualism, the plants are, in some functional sense, working with the organism rather than against it. These are different clinical orientations.

Hoffmann translates this conviction into a structural ecological model. He proposes that the self-healing individual sits at the center of a therapeutic ecology, “so called because the various components exist in relationship to each other and the wider world,” surrounded by four branches of therapy: medicine, bodywork, psychology, and spiritual technique.(Hoffmann, David, 2003) No single modality holds priority; each is understood in relation to the others and to the larger living context. The vocabulary is ecological rather than metaphysical, but the structure performs the same function as older vitalist frameworks: healing is relational, not a unidirectional intervention.

This orientation has a direct consequence for how Hoffmann categorizes herbal actions. He divides herbs into two broad classes. Normalizers are gentle herbs that “nourish the body in ways that support natural processes of growth, health, and renewal” (tonics and herbal foods, exemplified by nettles, cleavers, and chickweed). Effectors are herbs used to produce observable impacts on the body; they are subdivided into those whose effects arise from complex whole-plant interactions and those dominated by specific active chemicals “generally strong enough to mask any evidence of whole plant effects” and potentially poisonous at wrong doses.(Hoffmann, David, 2003) In practice, the vitalist orientation means normalizers come first: “the herbalist will focus on the use of such remedies, and will use stronger effectors only if absolutely necessary. In fact, chemically based effectors are used very sparingly in holistic herbalism. They are, however, the foundation of pharmacological medicine.”(Hoffmann, David, 2003) The taxonomy restates in clinical language the old vitalist priority: support the organism’s own processes rather than overriding them.

Hoffmann is candid about what Western herbal medicine lacks that makes this vitalist commitment philosophically incomplete. Traditional Chinese medicine, ayurveda, and unani each express their holistic frameworks as applications of coherent philosophical systems rooted in Confucian, Taoist, and Hindu thought, systems in which medical technique is inseparable from broader ideas about nature, cosmos, and the good life.(Hoffmann, David, 2003) Western herbalism has no comparable theoretical architecture. As of 2003, Hoffmann acknowledges that “the definitive text on Western holistic medicine — a guide for the practitioner that clearly illuminates these new and exciting perspectives — has yet to be written,” and that practitioners remain “still in the early stages” of a “maelstrom of activity.”(Hoffmann, David, 2003) This is a frank admission that contemporary phytotherapy’s vitalist self-understanding remains more clinical orientation than articulated theory, closer to Canguilhem’s exigence (a standing demand of life within the living for recognition of its specificity) than to the systematic vital principles of Barthez or the entelechies of Driesch.

Stapley, writing from the perspective of British herbal practice in 2024, traces the same gap but frames it differently. The scientific view, she argues, is “rediscovering lost knowledge” by translating older intuitions about the emotional and psychic dimensions of health into the currently acceptable terms of psychoneuroimmunology; the complex involvement of the endocrine and immune systems in emotional life is, she suggests, no less mysterious than a Celtic ritual charm — it simply speaks a modern vocabulary.(Stapley, 2024) The other axis of the vitalist commitment — the insistence on the whole plant rather than its chemical constituents — she grounds not in metaphysics but in pharmacological observation: prescribing the whole plant “shows due respect for the clear superiority of synergy of multiple constituents in nature when it comes to chemistry.”(Stapley, 2024) The two positions together — psychoneuroimmunology as the scientific translation of mind-body vitalism, and whole-plant synergy as the clinical translation of organismic wholeness — represent the contemporary practitioner form of a tradition that began with the Hippocratic conviction that nature works toward its own restoration.
