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.

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 focus of this paper is a fascinating but hitherto unstudied 1742 manuscript treatise by Johannes Daniel Schlichting (1705–1765) titled “Sapientiæ Problema” that contains something extremely rare in the mid-eighteenth century: a full-blown speculative cosmogony. As this article reveals, Schlichting developed a distinctive vital liquid matter in an effort to account for the generation of all natural bodies and combat the stamina-based theories that were dominant in his day. He hoped that his treatise would be published in the Philosophical Transactions (...) of the Royal Society, but an accompanying abridgment by the FRS Henry Baker (1698–1774) strongly implies that Schlichting’s speculative bent and desire to divulge causal explanations were unacceptable to the Englishman and generally ill-suited to the intellectual climate of mid-century England.

This essay explores an unstudied compendium to Margaret Cavendish’s 1655 Philosophical and Physical Opinions that was composed by the learned physician, plant anatomist, and secretary of the Royal Society, Nehemiah Grew. Despite the growing body of scholarship on Cavendish, minimal attention has been dedicated to her early reception. But studying this compendium provides some fascinating insights into how one of the foremost thinkers of her day read, emended, and manipulated her ideas. I propose that Grew turned to Cavendish’s work when (...) developing his substance theory in the years leading up to the publication of his 1682 The Anatomy of Plants, but that shifting intellectual tides led him to critique her version of material vitalism in his 1701 Cosmologia Sacra. Supported by a transcription of the compendium as an appendix, this article also sheds light on the role that early modern pedagogical techniques and memory tools played in shaping concepts of matter and mind.

This essay explores the use of stringed instruments (and in particular the harpsichord) as models of brain and cognitive function in eighteenth-century French medicine and natural philosophy. These comparisons were founded in part on the anatomical investigations of the latter half of the seventeenth century, which had established both the “fibrous” structure of the white and gray matter of the cerebrum and the vibratory movement the brain underwent in the performance of its functions. Musical instruments—and in particular the harpsichord—helped these (...) philosophers speculate about how the brain worked as the material instrument of sensation and thought: they were machines at once mechanical and affective, grounded in the materiality of their wooden boards and metal strings, yet symbolizing the rational—and immaterial—harmonies of music.

There is an enduring story about empiricism, which runs as follows: from Locke onwards to Carnap, empiricism is the doctrine in which raw sense-data are received through the passive mechanism of perception; experience is the effect produced by external reality on the mind or ‘receptors’. Empiricism on this view is the ‘handmaiden’ of experimental natural science, seeking to redefine philosophy and its methods in conformity with the results of modern science. Secondly, there is a story about materialism, popularized initially by (...) Marx and Engels and later restated as standard, ‘textbook’ history of philosophy in the English-speaking world. It portrays materialism as explicitly mechanistic, seeking to reduce the world of qualities, sensations, and purposive behaviour to a quantitative, usually deterministic physical scheme. Building on some recent scholarship, I aim to articulate the contrarian view according to which neither of these stories is true. On the contrary, empiricism turns out to be less ‘science-friendly’ and more concerned with moral matters; materialism reveals itself to be, in at least a large number of cases, a ‘vital’, anti-mechanistic doctrine which focuses on the unique properties of organic beings. This revision of two key philosophical episodes should reveal that our history of early modern philosophy is dependent to a great extent on ‘special interests’, whether positivistic or Kantian, and by extension lead us to rethink the relation and distinction between ‘science’ and ‘philosophy’ in this period.

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)
