The category of ‘organism’ has an ambiguous status: is it scientific or is it philosophical? Or, if one looks at it from within the relatively recent field or sub-field of philosophy of biology, is it a central, or at least legitimate category therein, or should it be dispensed with? In any case, it has long served as a kind of scientific “bolstering” for a philosophical train of argument which seeks to refute the “mechanistic” or “reductionist” trend, which has been perceived (...) as dominant since the 17th century, whether in the case of Stahlian animism, Leibnizian monadology, the neo-vitalism of Hans Driesch, or, lastly, of the “phenomenology of organic life” in the 20th century, with authors such as Kurt Goldstein, Maurice Merleau-Ponty, and Georges Canguilhem. In this paper I try to reconstruct some of the main interpretive ‘stages’ or ‘layers’ of the concept of organism in order to critically evaluate it. How might ‘organism’ be a useful concept if one rules out the excesses of ‘organismic’ biology and metaphysics? Varieties of instrumentalism and what I call the ‘projective’ concept of organism are appealing, but perhaps ultimately unsatisfying. (shrink)

Canguilhem is known to have regretted, with some pathos, that Life no longer serves as an orienting question in our scientific activity. He also frequently insisted on a kind of uniqueness of organisms and/or living bodies – their inherent normativity, their value-production and overall their inherent difference from mere machines. In addition, Canguilhem acknowledged a major debt to the German neurologist-theoretician Kurt Goldstein, author most famously of The Structure of the Organism in 1934; along with Merleau-Ponty, Canguilhem was the main (...) figure who introduced the work of Goldstein and his ‘phenomenology of embodiment’ into France. In this paper I inquire if we should view Canguilhem and Goldstein as ‘biochauvinists’, that is, as thinkers who consider that there is something inherently unique about biological entities as such, and if so, of what sort.

Newton’s impact on Enlightenment natural philosophy has been studied at great length, in its experimental, methodological and ideological ramifications. One aspect that has received fairly little attention is the role Newtonian “analogies” played in the formulation of new conceptual schemes in physiology, medicine, and life science as a whole. So-called ‘medical Newtonians’ like Pitcairne and Keill have been studied; but they were engaged in a more literal project of directly transposing, or seeking to transpose, Newtonian laws into quantitative models of (...) the body. I am interested here in something different: neither the metaphysical reading of Newton, nor direct empirical transpositions, but rather, a more heuristic, empiricist construction of Newtonian analogies. Figures such as Haller, Barthez, and Blumenbach constructed analogies between the method of celestial mechanics and the method of physiology. In celestial mechanics, they held, an unknown entity such as gravity is posited and used to mathematically link sets of determinate physical phenomena (e.g., the phases of the moon and tides). This process allows one to remain agnostic about the ontological status of the unknown entity, as long as the two linked sets of phenomena are represented adequately. Haller et. al. held that the Newtonian physician and physiologist can similarly posit an unknown called ‘life’ and use it to link various other phenomena, from digestion to sensation and the functioning of the glands. These phenomena consequently appear as interconnected, goal-oriented processes which do not exist either in an inanimate mechanism or in a corpse. In keeping with the empiricist roots of the analogy, however, no ontological claims are made about the nature of this vital principle, and no attempts are made to directly causally connect such a principle and observable phenomena. The role of the “Newtonian analogy” thus brings together diverse schools of thought, and cuts across a surprising variety of programs, models and practices in natural philosophy. (shrink)

Our aim in this paper is to bring to light the importance of the notion of économie animale in Montpellier vitalism, as a hybrid concept which brings together the structural and functional dimensions of the living body – dimensions which hitherto had primarily been studied according to a mechanistic model, or were discussed within the framework of Stahlian animism. The celebrated image of the bee-swarm expresses this structural-functional understanding of living bodies quite well: “One sees them press against each other, (...) mutually supporting each other, forming a kind of whole, in which each living part, in its own way, by means of the correspondence and directions of its motions, enables this kind of life to be sustained in the body” (Encyclopédie, article “Observation,” by Ménuret de Chambaud). What is important here is that every component part is always a living part, i.e., every structural unit is always functional. Interestingly, while the twin notions of ‘animal economy’ and organisation are presented as improvements over a mechanistic perspective, they are nonetheless compatible with an expanded sense of mechanism and by extension, with materialism as reflected notably in the writings of Ménuret and Bordeu. We thus propose both a revision and reconstruction of the historical status of the ‘animal economy’, and a reflection on its conceptual status. (shrink)

In this essay I seek to critically evaluate some forms of holism and organicism in biological thought, as a more deflationary echo to Gilbert and Sarkar's reflection on the need for an 'umbrella' concept to convey the new vitality of holistic concepts in biology (Gilbert and Sarkar 2000). Given that some recent discussions in theoretical biology call for an organism concept (from Moreno and Mossio’s work on organization to Kirschner et al.’s research paper in Cell, 2000, building on chemistry to (...) articulate what they called “molecular vitalism,” studying the “vitalistic” properties of molecular, cellular, and organismal function, and Pepper and Herron’s suggestion in their 2008 paper that organisms define a category that evolutionary biology cannot do without), the question, what concept of organicism are they calling for? To what extent are such claims philosophically committed to a non-naturalistic concept of organism as organizing centre, as a foundational rather than heuristic concept – or possibly a “biochauvinism,” to use Di Paolo’s term (Di Paolo 2009)? My aim in this paper is to conceptually clarify the forms of holism and organicism that are involved in these cases (and I acknowledge that the study of early 20th-century holisms [Peterson 2010] indicates that not all of them were in fact ‘organicist’ or ‘biologistic’). I suggest that contemporary holists are still potentially beholden to a certain kind of vitalism or “biochauvinism”; but that when they reduce their claims to mere heuristics, conversely, they risk losing sight of a certain kind of organizational “thickness”, a “vital materiality” (Wheeler 2010) which is characteristic of biological systems (Bechtel 2007). And I ask if it is possible to articulate a concept of biological holism or organicism which is neither an empirical ‘biochauvinism’ nor a metaphysical ‘vitalism’? (shrink)

My topic is the materialist appropriation of empiricism – as conveyed in the ‘minimal credo’ nihil est in intellectu quod non fuerit in sensu (which interestingly is not just a phrase repeated from Hobbes and Locke to Diderot, but is also a medical phrase, used by Harvey, Mandeville and others). That is, canonical empiricists like Locke go out of their way to state that their project to investigate and articulate the ‘logic of ideas’ is not a scientific project: “I shall (...) not at present meddle with the Physical consideration of the Mind” (Essay, I.i.2, in Locke 1975; which Kant gets exactly wrong in his reading of Locke, in the Preface to the A edition of the first Critique). Indeed, I have suggested elsewhere, contrary to a prevalent reading of Locke, that the Essay is not the extension to the study of the mind of the methods of natural philosophy; that he is actually not the “underlabourer” of Newton and Boyle he claims politely to be in the Epistle to the Reader (Wolfe and Salter 2009, Wolfe 2010). Rather, Locke says quite directly if we pay heed to such passages, “Our Business here is not to know all things, but those which concern our Conduct” (Essay, I.i.6). There would be more to say here about what this implies for our understanding of empiricism (see Norton 1981 and Gaukroger 2005), but instead I shall focus on a different aspect of this episode: how a non-naturalistic claim which falls under what we now call epistemology (a claim about the senses as the source of knowledge) becomes an ontology – materialism. That is, how an empiricist claim could shift from being about the sources of knowledge to being about the nature of reality (and/or the mind, in which case it needs, as David Hartley saw and Denis Diderot proclaimed more overtly, an account of the relation between mental processes and the brain). (David Armstrong, for one, denied that there could be an identification between empiricism and materialism on this point: eighteenth-century history of science seems to prove him wrong: see Armstrong 1968 and 1978.) Put differently, I want to examine the shift from the logic of ideas in the seventeenth century (Locke) to an eighteenth-century focus on what kind of ‘world’ the senses give us (Condillac), to an assertion that there is only one substance in the universe (Diderot, giving a materialist cast to Spinozism), and that we need an account of the material substrate of mental life. This is neither a ‘scientific empiricism’ nor a linear developmental process from philosophical empiricism to natural science, but something else again: the unpredictable emergence of an ontology on empiricist grounds. (shrink)

Sensibility, in any of its myriad realms – moral, physical, aesthetic, medical and so on – seems to be a paramount case of a higher-level, intentional property, not a basic property. Diderot famously made the bold and attributive move of postulating that matter itself senses, or that sensibility (perhaps better translated ‘sensitivity’ here) is a general or universal property of matter, even if he at times took a step back from this claim and called it a “supposition.” Crucially, sensibility is (...) here playing the role of a ‘booster’: it enables materialism to provide a full and rich account of the phenomena of conscious, sentient life, contrary to what its opponents hold: for if matter can sense, and sensibility is not a merely mechanical process, then the loftiest cognitive plateaus are accessible to materialist analysis, or at least belong to one and the same world as the rest of matter. This was noted by the astute anti-materialist critic, the Abbé Lelarge de Lignac, who, in his 1751 Lettres à un Amériquain, criticized Buffon for “granting to the body [la machine, a common term for the body at the time] a quality which is essential to minds, namely sensibility.” This view, here attributed to Buffon and definitely held by Diderot, was comparatively rare. If we look for the sources of this concept, the most notable ones are physiological and medical treatises by prominent figures such as Robert Whytt, Albrecht von Haller and the Montpellier vitalist Théophile de Bordeu. We then have, or so I shall try to sketch out, an intellectual landscape in which new – or newly articulated – properties such as irritability and sensibility are presented either as an experimental property of muscle fibers, that can be understood mechanistically (Hallerian irritability, as studied recently by Hubert Steinke and Dominique Boury) or a property of matter itself (whether specifically living matter as in Bordeu and his fellow montpelliérains Ménuret and Fouquet, or matter in general, as in Diderot). I am by no means convinced that it is one and the same ‘sensibility’ that is at issue in debates between these figures (as when Bordeu attacks Haller’s distinction between irritability and sensibility and claims that ‘his own’ property of sensibility is both more correct and more fundamental in organic beings), but I am interested in mapping out a topography of the problem of sensibility as property of matter or as vital force in mid-eighteenth-century debates – not an exhaustive cartography of all possible positions or theories, but an attempt to understand the ‘triangulation’ of three views: a vitalist view in which sensibility is fundamental, matching up with a conception of the organism as the sum of parts conceived as little lives (Bordeu et al.); a mechanist, or ‘enhanced mechanist’ view in which one can work upwards, step by step from the basic property of irritability to the higher-level property of sensibility (Haller); and, more eclectic, a materialist view which seeks to combine the mechanistic, componential rigour and explanatory power of the Hallerian approach, with the monistic and metaphysically explosive potential of the vitalist approach (Diderot). It is my hope that examining Diderot in the context of this triangulated topography of sensibility as property sheds light on his famous proclamation regarding sensibility as a universal property of matter. (shrink)

Denis Diderot’s natural philosophy is deeply and centrally ‘biologistic’: as it emerges between the 1740s and 1780s, thus right before the appearance of the term ‘biology’ as a way of designating a unified science of life (McLaughlin), his project is motivated by the desire both to understand the laws governing organic beings and to emphasize, more ‘philosophically’, the uniqueness of organic beings within the physical world as a whole. This is apparent both in the metaphysics of vital matter he puts (...) forth in works such as D’Alembert’s Dream (1769) and the more empirical concern with the mechanics of life in his manuscript Elements of Physiology, on which he worked during the last twenty years of his life. This ‘biologism’ obviously presents the interpreter of Diderot with some difficulties, notably as regards his materialism, given that contemporary forms of materialism have on the contrary strongly rejected notions of emergence, vitalism, teleology and any concepts appealing to unique, irreducible features of organisms. In response, some have described him as a ‘holist’ (Kaitaro) while others have emphasized his materialist, naturalist project (Bourdin, Wolfe). In what follows I examine a little-known aspect of Diderot’s articulation of his biological project: his statement in favour of epigenesis within the short but suggestive Encyclopédie article “Spinosiste.” Diderot was, of course, a partisan of epigenesis (the developmental-biological theory opposed to preformation, according to which beings develop by successive adjunction of layers of matter), but why include a statement in favour of a particular biological (or developmental) theory within an entry dealing with a philosopher, Spinoza, who does not seem to have been concerned at all with the specific properties of living beings, how they grow from embryonic to developed states, and so on? By trying to answer this question I also try and locate Diderot’s biological project in relation to what will become, in the years after his death, the project for a science called ‘biology’, with figures such as Treviranus and Lamarck. For it is not clear that the two can be easily correlated or causally linked: Diderot’s ‘epigenetic Spinozism’ is a different conceptual entity from what we find in histories of biology. (shrink)

The organism is neither a discovery like the circulation of the blood or the glycogenic function of the liver, nor a particular biological theory like epigenesis or preformationism. It is rather a concept which plays a series of roles – sometimes overt, sometimes masked – throughout the history of biology, and frequently in very normative ways, also shifting between the biological and the social. Indeed, it has often been presented as a key-concept in life science and the ‘theorization’ of Life, (...) but conversely has also been the target of influential rejections: as just an instrument of transmission for the selfish gene, but also, historiographically, as part of an outdated ‘vitalism’. Indeed, the organism, perhaps because it is experientially closer to the ‘body’ than to the ‘molecule’, is often the object of quasi-affective theoretical investments presenting it as essential, sometimes even as the pivot of a science or a particular approach to nature, while other approaches reject or attack it with equal force, assimilating it to a mysterious ‘vitalist’ ontology of extra-causal forces, or other pseudo-scientific doctrines. This paper does not seek to adjudicate between these debates, either in terms of scientific validity or historical coherence; nor does it return to the well-studied issue of the organism-mechanism tension in biology. Recent scholarship has begun to focus on the emergence and transformation of the concept of organism, but has not emphasized so much the way in which organism is a shifting, ‘go-between’ concept – invoked as ‘natural’ by some thinkers to justify their metaphysics, but then presented as value-laden by others, over and against the natural world. The organism as go-between concept is also a hybrid, a boundary concept or an epistemic limit case, all of which partly overlap with the idea of ‘nomadic concepts’. Thereby the concept of organism continues to function in different contexts – as a heuristic, an explanatory challenge, a model of order, of regulation, etc. – despite having frequently been pronounced irrelevant and reduced to molecules or genes. Yet this perpetuation is far removed from any ‘metaphysics of organism’, or organismic biology. (shrink)

I distinguish between ‘substantival’ and ‘functional’ forms of vitalism in the eighteenth century. Substantival vitalism presupposes the existence of a (substantive) vital force which either plays a causal role in the natural world as studied scientifically, or remains an immaterial, extra-causal entity. Functional vitalism tends to operate ‘post facto’, from the existence of living bodies to the search for explanatory models that will account for their uniquely ‘vital’ properties better than fully mechanistic models can. I discuss representative figures of the (...) Montpellier school (Bordeu, Ménuret, Fouquet) as functional rather than substantival vitalists, and suggest an additional point regarding the reprisal of vitalism(s) in the 20th century, from Driesch to Canguilhem: that in addition to the substantival and functional varieties, we encounter a third species of vitalism, which I term ‘attitudinal’, as it argues for vitalism as a kind of attitude. (shrink)

In reflecting on the relation between early empiricist conceptions of the mind and more experimentally motivated materialist philosophies of mind in the mid-eighteenth century, I suggest that we take seriously the existence of what I shall call ‘phantom philosophical projects’. A canonical empiricist like Locke goes out of his way to state that their project to investigate and articulate the ‘logic of ideas’ is not a scientific project: “I shall not at present meddle with the Physical consideration of the Mind” (...) (Essay, I.i.2). An equally prominent thinker, Immanuel Kant, seems to make an elementary mistake, given such a clear statement, when he claims that Locke’s project was a “physiology of the understanding,” in the Preface to the A edition of the first Critique). A first question, then, would be: what is this physiology of the understanding, if it was not Locke’s project? Did anyone undertake such a project? If not, what would it have resembled? My second and related case comes out of a remark the Hieronymus Gaub makes in a letter to Charles Bonnet of 1761: criticizing materialist accounts of mind and mind-body relations such as La Mettrie’s, Gaub suggests that what is needed is a thorough study of the “mechanics of the soul,” and that Bonnet could write such a study. What is the mechanics of the soul, especially given that it is presented as a non-materialist project? To what extent does it resemble the purported “physiology of the understanding”? And more generally, what do both of these phantom projects have to do with a process we might describe as a ‘naturalization of the soul’? (shrink)

Intellectual history still quite commonly distinguishes between the episode we know as the Scientific Revolution, and its successor era, the Enlightenment, in terms of the calculatory and quantifying zeal of the former—the age of mechanics—and the rather scientifically lackadaisical mood of the latter, more concerned with freedom, public space and aesthetics. It is possible to challenge this distinction in a variety of ways, but the approach I examine here, in which the focus on an emerging scientific field or cluster of (...) disciplines—the ‘life sciences’, particularly natural history, medicine, and physiology —is, not Romantically anti-scientific, but resolutely anti-mathematical. Diderot bluntly states, in his Thoughts on the interpretation of nature, that “We are on the verge of a great revolution in the sciences. Given the taste people seem to have for morals, belles-lettres, the history of nature and experimental physics, I dare say that before a hundred years, there will not be more than three great geometricians remaining in Europe. The science will stop short where the Bernoullis, the Eulers, the Maupertuis, the Clairauts, the Fontaines and the D’Alemberts will have left it.... We will not go beyond.” Similarly, Buffon in the first discourse of his Histoire naturelle speaks of the “over-reliance on mathematical sciences,” given that mathematical truths are merely “definitional” and “demonstrative,” and thereby “abstract, intellectual and arbitrary.” Earlier in the Thoughts, Diderot judges “the thing of the mathematician” to have “as little existence in nature as that of the gambler.” Significantly, this attitude—taken by great scientists who also translated Newton or wrote careful papers on probability theory, as well as by others such as Mandeville—participates in the effort to conceptualize what we might call a new ontology for the emerging life sciences, very different from both the ‘iatromechanism’ and the ‘animism’ of earlier generations, which either failed to account for specifically living, goal-directed features of organisms, or accounted for them in supernaturalistic terms by appealing to an ‘anima’ as explanatory principle. Anti-mathematicism here is then a key component of a naturalistic, open-ended project to give a successful reductionist model of explanation in ‘natural history’, a model which is no more vitalist than it is materialist—but which is fairly far removed from early modern mechanism.

ABSTRACTMaterialism is the view that everything that is real is material or is the product of material processes. It tends to take either a ‘cosmological’ form, as a claim about the ultimate nature of the world, or a more specific ‘psychological’ form, detailing how mental processes are brain processes. I focus on the second, psychological or cerebral form of materialism. In the mid-to-late eighteenth century, the French materialist philosopher Denis Diderot was one of the first to notice that any self-respecting (...) materialist had to address the question of the status and functional role of the brain, and its relation to our mental life. After this the topic grew stale, with knee-jerk reiterations of ‘psychophysical identity’ in the nineteenth-century, and equally rigid assertions of anti-materialism. In 1960s philosophy of mind, brain–mind materialism reemerged as ‘identity theory’, focusing on the identity between mental processes and cerebral processes. In contrast, Diderot’s cerebral materialism allows... (shrink)

The materialist approach to the body is often, if not always understood in ‘mechanistic’ terms, as the view in which the properties unique to organic, living embodied agents are reduced to or described in terms of properties that characterize matter as a whole, which allow of mechanistic explanation. Indeed, from Hobbes and Descartes in the 17th century to the popularity of automata such as Vaucanson’s in the 18th century, this vision of things would seem to be correct. In this paper (...) I aim to correct this inaccurate vision of materialism. On the contrary, the materialist project on closer consideration reveals itself to be, significantly if not exclusively, (a) a body of theories specifically focused on the contribution that ‘biology’ or rather ‘natural history’ and physiology make to metaphysical debates, (b) much more intimately connected to what we now call ‘vitalism’ (a case in point is the presence of Théophile de Bordeu, a prominent Montpellier physician and theorist of vitalism, as a fictional character and spokesman of materialism, in Diderot’s novel D’Alembert’s Dream), and ultimately (c) an anti-mechanistic doctrine which focuses on the unique properties of organic beings. To establish this revised vision of materialism I examine philosophical texts such as La Mettrie’s Man a Machine and Diderot’s D’Alembert’s Dream; medical entries in the Encyclopédie by physicians such as Ménuret and Fouquet; and clandestine combinations of all such sources (Fontenelle, Gaultier and others).

Well prior to the invention of the term ‘biology’ in the early 1800s by Lamarck and Treviranus, and also prior to the appearance of terms such as ‘organism’ under the pen of Leibniz in the early 1700s, the question of ‘Life’, that is, the status of living organisms within the broader physico-mechanical universe, agitated different corners of the European intellectual scene. From modern Epicureanism to medical Newtonianism, from Stahlian animism to the discourse on the ‘animal economy’ in vitalist medicine, models (...) of living being were constructed in opposition to ‘merely anatomical’, structural, mechanical models. It is therefore curious to turn to the ‘passion play’ of the Scientific Revolution – whether in its early, canonical definitions or its more recent, hybridized, reconstructed and expanded versions: from Koyré to Biagioli, from Merton to Shapin – and find there a conspicuous absence of worry over what status to grant living beings in a newly physicalized universe. Neither Harvey, nor Boyle, nor Locke (to name some likely candidates, the latter having studied with Willis and collaborated with Sydenham) ever ask what makes organisms unique, or conversely, what does not. In this paper I seek to establish how ‘Life’ became a source of contention in early modern thought, and how the Scientific Revolution missed the controversy. (shrink)

This book provides an overview of key features of (philosophical) materialism, in historical perspective. It is, thus, a study in the history and philosophy of materialism, with a particular focus on the early modern and Enlightenment periods, leading into the 19th and 20th centuries. For it was in the 18th century that the word was first used by a philosopher (La Mettrie) to refer to himself. Prior to that, ‘materialism’ was a pejorative term, used for wicked thinkers, as a near-synonym (...) to ‘atheist’, ‘Spinozist’ or the delightful ‘Hobbist’. The book provides the different forms of materialism, particularly distinguished into claims about the material nature of the world and about the material nature of the mind, and then focus on materialist approaches to body and embodiment, selfhood, ethics, laws of nature, reductionism and determinism, and overall, its relationship to science. For materialism is often understood as a kind of philosophical facilitator of the sciences, and the author want to suggest that is not always the case. Materialism takes on different forms and guises in different historical, ideological and scientific contexts as well, and the author wants to do justice to that diversity. Figures discussed include Lucretius, Hobbes, Gassendi, Spinoza, Toland, Collins, La Mettrie, Diderot, d’Holbach and Priestley; Büchner, Bergson, J.J.C. Smart and D.M. Armstrong. (shrink)

Rather, Locke says quite directly if we pay heed to such passages, “Our Business here is not to know all things, but those which concern our Conduct”. There would be more to say here about what this implies for our understanding of empiricism, but instead I shall focus on a different aspect of this episode: how a non-naturalistic claim which falls under what we now call epistemology becomes an ontology—materialism.

This volume focuses on the development of empiricism as an interest in the body - as both the object of research and the subject of experience.

In this paper we suggest a revisionist perspective on two significant figures in early modern life science and philosophy: William Harvey and John Locke. Harvey, the discoverer of the circulation of the blood, is often named as one of the rare representatives of the ‘life sciences’ who was a major figure in the Scientific Revolution. While this status itself is problematic, we would like to call attention to a different kind of problem: Harvey dislikes abstraction and controlled experiments (aside from (...) the ligature experiment in De Motu Cordis), tends to dismiss the value of instruments such as the microscope, and emphasizes instead the privileged status of ‘observed experience’. To use a contemporary term, Harvey appears to rely on, and chiefly value, ‘tacit knowledge’. Secondly, Locke’s project is often explained with reference to the image he uses in the Epistle to the Reader of his Essay, that he was an “underlabourer” of the sciences. In fact, despite the significant medical phase of his career, Locke’s ‘empiricism’ turns out to be above all a practical (i.e. ‘moral’) project, which focuses on the delimitation of our powers in order to achieve happiness, and rejects the possibility of naturalizing knowledge. When combined, these two cases suggest a different view of some canonical moments in early modern natural philosophy. (shrink)

The species of vitalism discussed here is a malleable construct, often with a poisonous reputation (but one which I want to rehabilitate), hovering in between the realms of the philosophy of biology, the history of medicine, and the scientific background of the Radical Enlightenment (case in point, the influence of vitalist medicine on Diderot). This is a more vital vitalism, or at least a more ‘biologistic,’ ‘embodied,’ medicalized vitalism. I distinguish between what I would call ‘substantival’ and ‘functional’ forms of (...) vitalism, as applied to the eighteenth century. Substantival vitalism presupposes the existence of something like a (substantive) vital force which either plays a causal role in the natural world as studied by scientific means, or remains a kind of hovering, extra-causal entity. Functional vitalism tends to operate “post facto,” from the existence of living bodies to the desire to find explanatory models that will do justice to their uniquely ‘vital’ properties in a way that fully mechanistic models (such as Cartesian mechanism) cannot. I discuss some representative figures of the Montpellier school as being functional rather than substantival vitalists, particularly as regards the models of organic organization which they develop, and make some suggestions as to how these relate to the then-nascent science of biology.

In the mid-to-late eighteenth century, the French materialist philosopher Denis Diderot was one of the first to notice that any self-respecting (...) materialist had to address the question of the status and functional role of the brain, and its relation to our mental life. After this the topic grew stale, with knee-jerk reiterations of ‘psychophysical identity’ in the nineteenth-century, and equally rigid assertions of anti-materialism. In 1960s philosophy of mind, brain–mind materialism reemerged as ‘identity theory’, focusing on the identity between mental processes and cerebral processes. In contrast, Diderot’s cerebral materialism allows for a more culturally sedimented sense of the brain, which he described in his late Elements of Physiology as a ‘book – except it is a book which reads itself’. Diderot thus provides a lesson for materialism as it reflects on the status of the brain, science and culture. (shrink)

At the very beginning of L’Homme-Machine, La Mettrie claims that Leibnizians with their monads have “rather spiritualized matter than materialized the soul”; a few years later Pierre-Louis Moreau de Maupertuis, President of the Berlin Academy of Sciences and natural philosopher with a strong interest in the modes of transmission of ‘genetic’ information, conceived of living minima which he termed molecules, “endowed with desire, memory and intelligence,” in his Système de la nature ou Essai sur les corps organisés. This text first (...) appeared in Latin in 1751 under the title Dissertatio inauguralis metaphysica de universali naturae systemate, with the pseudonym Dr Baumann; it was translated by Maupertuis in 1754 as Essai sur la formation des corps organisés and was later included in his 1756 Œuvres under the title Système de la nature. Now, it is clear that Maupertuis was a kind of Leibnizian; and that his molecule possessed higher-level, ‘mental’ properties. In that sense he falls under the first category described by La Mettrie. But he was also involved in a debate on this issue with Diderot, who put forth a sustained critique of Maupertuis’ theory of the molecule in the additions to his 1753 Pensées sur l’interprétation de la nature. Where Maupertuis attributes higher-level properties to his living minima, Diderot argues that these properties are ‘organizational’, i.e., they can only be properties of the whole. At issue here is the degree of commitment to a form of materialism. (shrink)

Introduction to edited volume on vitalism and/in the life sciences, 1800-2010.

A chapter on the specifically 'medical' Epicureanism of La Mettrie, connecting his materialist approach to mind-body issues and his hedonistic ethics.

In this paper, we reflect on the connection between the notions of organism and organisation, with a specific interest in how this bears upon the issue of the reality of the organism. We do this by presenting the case of Buffon, who developed complex views about the relation between the notions of “organised” and “organic” matter. We argue that, contrary to what some interpreters have suggested, these notions are not orthogonal in his thought. Also, we argue that Buffon has a (...) view in which organisation is not just ubiquitous, but basic and fundamental in nature, and hence also fully natural. We suggest that he can hold this view because of his anti-mathematicism. Buffon’s case is interesting, in our view, because he can regard organisation, and organisms, as perfectly natural, and can admit their reality without invoking problematic supernaturalist views, and because he allows organisation and the organismal to come in kinds and degrees. Thus, his view tries to do justice to two cautionary notes for the debate on the reality of the organism: the need for a commitment to a broadly naturalist perspective, and the need to acknowledge the interesting features of organisms through which we make sense of them.

Locke and Leibniz deny that there are any such beings as ‘monsters’ (anomalies, natural curiosities, wonders, and marvels), for two very different reasons. For Locke, monsters are not ‘natural kinds’: the word ‘monster’ does not individuate any specific class of beings ‘out there’ in the natural world. Monsters depend on our subjective viewpoint. For Leibniz, there are no monsters because we are all parts of the Great Chain of Being. Everything that happens, happens for a reason, including a monstrous birth. (...) But what about materialism? Well, beginning with the anatomical interest into ‘monstrous births’ in the French Académie des Sciences in the first three decades of the eighteenth century, there is a shift away from ‘imaginationist’ claims such as those of Malebranche, that if a woman gives birth to a monstrous child it is a consequence of something she imagined. Anatomists such as Lemery and Winslow try to formulate a strictly mechanical explanation for such events, rejecting moral and metaphysical explanations. Picking up on this work, materialist thinkers like Diderot are compelled to reject the very idea of monsters. We are all material beings produced according to the same mechanisms or laws, some of us are more ‘successful’ products than others, i.e. some live longer than others. In his late Eléments de physiologie he says “L’homme est un effet commun, le monstre un effet rare.” Ultimately he arrives at a materialist version of Leibniz’s position: there are no monsters, we are all monsters in each other’s eyes, at one time or another. This conclusion is a pregnant one in light of twentieth century interest in the problem of ‘the normal and the pathological’ (Canguilhem), and the broader question of how materialism relates to the biological world.

There is a familiar opposition between a ‘Scientific Revolution’ ethos and practice of experimentation, including experimentation on life, and a ‘vitalist’ reaction to this outlook. The former is often allied with different forms of mechanism – if all of Nature obeys mechanical laws, including living bodies, ‘iatromechanism’ should encounter no obstructions in investigating the particularities of animal-machines – or with more chimiatric theories of life and matter, as in the ‘Oxford Physiologists’. The latter reaction also comes in different, perhaps irreducibly (...) heterogeneous forms, ranging from metaphysical and ethical objections to the destruction of life, as in Margaret Cavendish, to more epistemological objections against the usage of instruments, the ‘anatomical’ outlook and experimentation, e.g. in Locke and Sydenham. But I will mainly focus on a third anti-interventionist argument, which I call ‘vitalist’ since it is often articulated in the writings of the so-called Montpellier Vitalists, including their medical articles for the Encyclopédie. The vitalist argument against experimentation on life is subtly different from the metaphysical, ethical and epistemological arguments, although at times it may borrow from any of them. It expresses a Hippocratic sensibility – understood as an artifact of early modernity, not as some atemporal trait of medical thought – in which Life resists the experimenter, or conversely, for the experimenter to grasp something about Life, it will have to be without torturing or radically intervening in it. I suggest that this view does not have to imply that Nature is something mysterious or sacred; nor does the vitalist have to attack experimentation on life in the name of some ‘vital force’ – which makes it less surprising to find a vivisectionist like Claude Bernard sounding so close to the vitalists.

In selected texts by Diderot, including the Encyclopédie article “Cabinet d’histoire naturelle” (along with his comments in the article “Histoire nat-urelle”), the Pensées sur l’interprétation de la nature and the Salon de 1767, I examine the interplay between philosophical naturalism and the recognition of the irreducible nature of artifice, in order to arrive at a provisional definition of Diderot’s vision of Nature as “une femme qui aime à se travestir.” How can a metaphysics in which the concept of Nature has (...) a normative status, also ultimately consider it to be something necessarily artificial? Historically, the answer to this question involves the project of natural history. A present-day reconstruction would have to make sense of this project and relate it to the vision of Nature expressed in Diderot’s phrase. In addition, it would hopefully pinpoint the difference between this brand of Enlightenment naturalism and contemporary naturalism, and by extension, allow us to understand a bit more about what naturalism is in general.

In his Philosophical Inquiry concerning Human Liberty (1717), the English deist Anthony Collins proposed a complete determinist account of the human mind and action, partly inspired by his mentor Locke, but also by elements from Bayle, Leibniz and other Continental sources. It is a determinism which does not neglect the question of the specific status of the mind but rather seeks to provide a causal account of mental activity and volition in particular; it is a ‘volitional determinism’. Some decades later, (...) Diderot articulates a very similar determinism, which seeks to recognize the existence of “causes proper to man” (as he says in the Réfutation d’Helvétius). The difference with Collins is that now biological factors are being taken into account. Obviously both the ‘volitional’ and the ‘biological’ forms of determinism are noteworthy inasmuch as they change our picture of the nature of determinism itself, but my interest here is to compare these two determinist arguments, both of which are broadly Spinozist in nature – and as such belong to what Jonathan Israel called in his recent book “the radical Enlightenment,” i.e. a kind of underground Enlightenment constituted by Spinozism – and to see how Collins’ specifically psychological vision and Diderot’s specifically biological vision correspond to their two separate national contexts: determinism in France in the mid-1750s was a much more medico-biological affair than English determinism, which appears to be on a ‘path’ leading to Mill and associationist psychology.

This is an introduction to a collection of articles on the conceptual history of epigenesis, from Aristotle to Harvey, Cavendish, Kant and Erasmus Darwin, moving into nineteenth-century biology with Wolff, Blumenbach and His, and onto the twentieth century and current issues, with Waddington and epigenetics. The purpose of the topical collection is to emphasize how epigenesis marks the point of intersection of a theory of biological development and a theory of active matter. We also wish to show that the concept (...) of epigenesis existed prior to biological theorization and that it continues to permeate thinking about development in recent biological debates. (shrink)

The concept of self has preeminently been asserted (in its many versions) as a core component of anti-reductionist, antinaturalistic philosophical positions, from Descartes to Husserl and beyond, with the exception of some hybrid or intermediate positions which declare rather glibly that, since we are biological entities which fully belong to the natural world, and we are conscious of ourselves as 'selves', therefore the self belongs to the natural world (this is characteristic e.g. of embodied phenomenology and enactivism). Nevertheless, from Cudworth (...) and More’s attacks on materialism all the way through twentieth-century argument against naturalism, the gulf between selfhood and the world of Nature appears unbridgeable. In contrast, my goal in this paper is to show that early modern materialism could yield a theory of the self according to which (1) the self belongs to the world of external relations (Spinoza), such that no one fact, including supposedly private facts, is only accessible to a single person; (2) the self can be reconstructed as a sense of “organic unity” which could be a condition for biological individuality (a central text here is Diderot’s 1769 Rêve de D’Alembert); yet this should not lead us to espouse a Romantic concept of organism as foundational or even ineffable subjectivity (a dimension present in Leibniz and made explicit in German idealism); (3) what we call 'self' might simply be a dynamic process of interpretive activity undertaken by the brain. This materialist theory of the self should not neglect the nature of experience, but it should also not have to take at face value the recurring invocations of a better, deeper “first-person perspective” or “first-person science.”. (shrink)

Vitalism was long viewed as the most grotesque view in biological theory: appeals to a mysterious life-force, Romantic insistence on the autonomy of life, or worse, a metaphysics of an entirely living universe. In the early twentieth century, attempts were made to present a revised, lighter version that was not weighted down by revisionary metaphysics: “organicism”. And mainstream philosophers of science criticized Driesch and Bergson’s “neovitalism” as a too-strong ontological commitment to the existence of certain entities or “forces”, over and (...) above the system of causal relations studied by mechanistic science, rejecting the weaker form, organicism, as well. But there has been some significant scholarly “push-back” against this orthodox attitude, notably pointing to the 18th-century Montpellier vitalists to show that there are different historical forms of vitalism, including how they relate to mainstream scientific practice. Additionally, some trends in recent biology that run counter to genetic reductionism and the informational model of the gene present themselves as organicist. Here, we examine some cases of vitalism in the twentieth century and today, not just as a historical form but as a significant metaphysical and scientific model. We argue for vitalism’s conceptual originality without either reducing it to mainstream models of science or presenting it as an alternate model of science, by focusing on historical forms of vitalism, logical empiricist critiques thereof and the impact of synthetic biology on current theorizing of vitalism. (shrink)

Vitalism, from its early modern to its Enlightenment forms (from Glisson and Willis to La Caze and Barthez), is notoriously opposed to intervention into the living sphere. Experiment, quantification, measurement are all ‘vivisectionist’, morally suspect and worse, they alter and warp the ‘life’ of the subject. They are good for studying corpses, not living individuals. This much is well known, and it has disqualified vitalist medicine from having a place in standard histories of medicine, until recent, post-Foucauldian maneuvers have sought (...) to change the situation (but for unrelated, contextualist reasons). What is perhaps more suprising is that if we consider the emergence of medical ‘theory’ as a whole, from Harvey through to Locke and Sydenham, is the presence of a sustained anti-experimentalist line of argument, and this from the ‘empiricist’ (not Cartesian or Boerhaavian rationalist) side. It would seem then that ‘empiricks’, medical empiricists and other protagonists of an ‘embodied empiricism’ are not Boylean experimentalists who seek to map out Nature in its transparency, but deliberately archaic, Hippocratic observers of living bodies. (shrink)

Empiricism is a claim about the contents of the mind: its classic slogan is nihil est in intellectu quod non fuerit in sensu, ‘there is nothing in the mind (intellect, understanding) which is not first in the senses’. As such, it is not a claim about the fundamental nature of the world as material. I focus here on in an instance of what one might term the materialist appropriation of empiricism. One major component in the transition from a purely epistemological (...) claim about the mind and its contents, to an ontological claim about the nature of the world, is the new focus on brain-mind relations in the eighteenth century. Here I examine a Lockean trajectory as exemplified in Joseph Priestley’s 1777 Disquisitions Relating to Matter and Spirit. But Locke explicitly ruled out that his inquiry into the logic of ideas amounted to a ‘physical consideration of the mind’. What does it mean, then, for Priestley to present himself as continuing a Lockean tradition, while presenting mental processes as tightly identified with ‘an organical structure such as that of the brain’ (although he was not making a strict identity claim as we might understand it, post-Smart and Armstrong)? One issue here is that of Priestley's source of ‘empirical data’ regarding the correlation and indeed identification of mental and cerebral processes. David Hartley’s theory in his 1749 Observations on Man was, as is well known, republished in abridged form by Priestley, but he discards Hartley's 'vibratory neurophysiology' while retaining the associationist framework, although not because he disagreed with the former. Yet Hartley was at the very least, strongly agnostic about metaphysical issues (and it is difficult to study these authors while bracketing off religious considerations). One could see Locke and Hartley as articulating programs for the study of the mind which were more or less naturalistic (more strongly so in Hartley’s case) while avoiding ‘materialism’ per se; in contrast, Priestley bit the (materialist) bullet. In this paper I examine Priestley’s appropriation and reconstruction of this ‘micro-tradition’, while emphasizing its problems. (shrink)

We argue for a conception of ‘philosophy of biology before biology’ which is neither internalist study of biological doctrines, nor a reconstruction of the role philosophical concepts might have played in the constitution of biology as science, but rather a kind of interplay between metaphysical and empirical issues. This should have an impact both on our present understanding of philosophy of biology, given that it is necessarily conditioned by a very specific history and historiography, and on our understanding of how (...) biology as a science of life became unified. (shrink)

The category of« organism » has an ambiguous status: scientific or philosophical? In any case, it has long served as a kind of scientific « bolstering » for a philosophical train of argument which seeks to refute the « mechanistic » or « reductionist » trend, which is seen as dominant since the 17th century, whether in the case of Stahlian animism, Leibnizian monadology, the neo-vitalism of Hans Driesch, or, lastly, of the « phenomenology of organic life » in the (...) 20th century, with authors such as Goldstein, Straws, and Weizsäcker, whose influence on Merleau-Ponty but also Canguilhem is obvious. The aim of this article is both to bring to light the sedimentation of this category and to give a critical evaluation of it, in other words, to sec in what way it might still be useful once one has eliminated the possibility of any « organicist » excesses. I suggest a notion of organism as an instrumental fiction. (shrink)

In his Système de la nature ou Essai sur les corps organisés, Pierre-Louis Moreau de Maupertuis, President of the Berlin Academy of Sciences and a natural philosopher with a strong interest in the modes of transmission of 'genetic' information, described living minima which he termed molecules, “endowed with desire, memory and intelligence.” Now, Maupertuis was a Leibnizian of sorts; his molecules possessed higher-level, 'mental' properties, recalling La Mettrie's statement in L'Homme-Machine, that Leibnizians have “rather spiritualized matter than materialized the soul.” (...) But Maupertuis also debated this issue with Diderot, who critiqued this theory in the additions to his 1753 Pensées sur l'interprétation de la nature. Where Maupertuis attributes higher-level properties to his living minima, Diderot argues that these can only be 'organizational', i.e., properties of the whole. At issue here is the degree of commitment to a form of materialism. (shrink)

A certain reading of Descartes, which we refer to as ‘the embodied Descartes’, is emerging from recent scholarship on L’Homme, in keeping with the interpretive trend which emphasizes Descartes’s identity as a natural philosopher. This reading complicates our understanding of Descartes’s philosophical project: far from strictly separating human minds from bodies, the embodied Descartes keeps them tightly integrated, while animal bodies behave in ways quite distinct from those of other pieces of extended substance. Here, we identify three categories of embodiment (...) in contemporary readings of Descartes’s physiology: bodily health and function, embodied reflex and memory, and embodied cognition. All present more or less strong versions of the embodied Descartes. Together, they constitute a compelling reading of a Cartesian natural philosophy that, if not expressly antidualist, is an awfully long way from the canonical picture. (shrink)

From Hegel to Engels, Sartre and Ruyer (Ruyer, 1933), to name only a few, materialism is viewed as a necropolis, or the metaphysics befitting such an abode; many speak of matter’s crudeness, bruteness, coldness or stupidity. Science or scientism, on this view, reduces the living world to ‘dead matter’, ‘brutish’, ‘mechanical, lifeless matter’, thereby also stripping it of its freedom (Crocker, 1959). Materialism is often wrongly presented as ‘mechanistic materialism’ – with ‘Death of Nature’ echoes of de-humanization and hostility to (...) the Scientific Revolution (which knew nothing of materialism!), also a powerful Christian theme in Cudworth, Clarke and beyond (Overhoff, 2000). Here I challenge this view, building on some aspects of Israel’s Radical Enlightenment concept (Israel, 2001), which has been controversial but for my purposes is a useful claim about the dissemination of a home-grown Spinozism, sometimes reformulated as an ontology of the life sciences, an aspect Israel does not address (compare Secrétan et al., eds., 2007; Citton, 2006). First, I examine some ‘moments’ of radical Enlightenment materialism such as La Mettrie and Diderot (including his Encyclopédie entry “Spinosiste”), but also anonymous, clandestine texts such as L’Âme Matérielle, to emphasize their distinctive focus on the specific existence of organic beings. Second, I show how this ‘embodied’, non-mechanistic character of Enlightenment ‘vital materialism’ makes it different from other episodes, and perhaps more of an ethics than is usually thought (also via the figure of the materialist as ‘laughing philosopher’). Third, I reflect on what this implies for our image of the Enlightenment – no longer a Frankfurt School and/or Foucaldian vision of ‘discipline’, regimentation and order (as in Mayr, 1986) – but ‘vital’, without, conversely, being a kind of holist vitalism “at odds with the universalizing discourse of Encyclopedist materialism, with its insistence on the uniformity of nature and the universality of physical laws” (Williams, 2003): vital materialism is still materialism. Its ethics tends towards hedonism, but its most radical proponents (Diderot, La Mettrie and later Sade) disagree as to what this means. (shrink)

In debates between holism and reductionism in biology, from the early 20th century to more recent re-enactments involving genetic reductionism, developmental systems theory, or systems biology, the role of chance – the presence of theories invoking chance as a strong explanatory principle – is hardly ever acknowledged. Conversely, Darwinian models of chance and selection (Dennett 1995, Kupiec 1996, Kupiec 2009) sit awkwardly with reductionist and holistic concepts, which they alternately challenge or approve of. I suggest that the juxtaposition of chance (...) and the holism-reductionism pair (at multiple levels, ontological and methodological, pertaining to the vision of scientific practice as well as to the foundations of a vision of Nature, implicit or explicit) allows the theorist to shed some new light on these perennial tensions in the conceptualisation of Life.

my introduction to special issue of Science in Context on 18c vitalism.

We have been accustomed at least since Kant and mainstream history of philosophy to distinguish between the ‘mechanical’ and the ‘teleological’; between a fully mechanistic, quantitative science of Nature exemplified by Newton and a teleological, qualitative approach to living beings ultimately expressed in the concept of ‘organism’ – a purposive entity, or at least an entity possessed of functions. The beauty of this distinction is that it seems to make intuitive sense and to map onto historical and conceptual constellations in (...) medicine, physiology and the related natural -philosophical discussions on the status of the body versus that of the machine. In this presentation I argue that the distinction between mechanism and teleology is imprecise and flawed, on the basis of a series of examples: the presence of ‘functional’ or ‘purposive’ features even in Cartesian physiology; work such as that of Richard Lower’s on animal respiration; the fact that the model of the ‘body-machine’ is not at all a mechanistic reduction of organismic properties to basic physical properties but on the contrary a way of emphasizing the uniqueness of organic life; and the concept of ‘animal economy’ in vitalist medical theory, which I present as a kind of ‘teleo-mechanistic’ concept of organism – neither mechanical nor teleological.

The eminent French biologist and historian of biology, François Jacob, once notoriously declared “On n’interroge plus la vie dans les laboratoires”: laboratory research no longer inquires into the notion of ‘Life’. Nowadays, as David Hull puts it, “both scientists and philosophers take ontological reduction for granted… Organisms are ‘nothing but’ atoms, and that is that.” In the mid-twentieth century, from the immediate post-war period to the late 1960s, French philosophers of science such as Georges Canguilhem, Raymond Ruyer and Gilbert Simondon (...) returned to Jacob’s statement with an odd kind of pathos: they were determined to reverse course. Not by imposing a different kind of research program in laboratories, but by an unusual combination of historical and philosophical inquiry into the foundations of the life sciences (particularly medicine, physiology and the cluster of activities that were termed ‘biology’ in the early 1800s). Even in as straightforwardly scholarly a work as La formation du concept de réflexe aux XVIIe et XVIIIe siècles (1955), Canguilhem speaks oddly of “defending vitalist biology,” and declares that Life cannot be grasped by logic (or at least, “la vie déconcerte la logique”). Was all this historical and philosophical work merely a reassertion of ‘mysterian’, magical vitalism? In order to answer this question we need to achieve some perspective on Canguilhem’s ‘vitalism’, notably with respect to its philosophical influences such as Kurt Goldstein. (shrink)

Monsters as a category seem omnipresent in early modern natural philosophy, in what one might call a “long” early modern period stretching from the Renaissance to the late eighteenth century, when the science of teratology emerges. We no longer use this term to refer to developmental anomalies (whether a two-headed calf, an individual suffering from microcephaly or Proteus syndrome) or to “freak occurrences” like Mary Toft’s supposedly giving birth to a litter of rabbits, in Surrey in the early eighteenth-century (Todd (...) 1995). But the term itself has a rich semantic history, coming from the Latin verb monstrare (itself deriving from monere, to remind, warn, advise), “to show,” from which we also get words like “monitor,” “admonish,” “monument” and “premonition”; hence there are proverbs like, in French, le monstre est ce qui montre, difficult to render in English: “the monsters is that which shows.” Scholars have discussed how this “monstrative” dimension of the monster is in fact twofold: on the one hand, and most awkwardly, the monster is an individual who is “pointed at,” who is shown; on the other hand, the monster is a sign, a portent, an omen, and in that sense “shows us” something (on the complex semantic history of the term across Indo-European languages see Ochsner 2005). The latter dimension persists in naturalized form in the early modern period when authors like Bacon, Fontenelle or William Hunter insist that monsters (or anomalies) can show us something of the workings of Nature.
