A Karger 'Publishing Highlights 1890-2015' title This 2nd, revised edition is still the reference work available in print and electronically on Paracelsus by the Paracelsus authority. Furthermore, it makes a very good read. See also Pagel's last book The Smiling Spleen on Paracelsianism as a historical phenomenon. '...a work in the brilliant tradition of biographical research... even the casual reader will be impressed to learn that, four centuries ago, the man who had the courage to burn in public the writings (...) of Avicenna, recognised pulmonary disease in miners as an occupational hazard, cretinism and goitre as endemic in certain areas, and chorea and hysteria as manifestations of disease, not demonic possession.'

We study here the reception by their contemporaries of Antoine de Villon's and étienne de Clave's anti-Aristotelian, almost materialistic and atomistic theses, which they intended to support publicly in Paris in 1624, using chemical experiments to this purpose. After surveying the intellectual context which could have then nourished an atomism based upon chemical experiments, we go on to show how these theses, far from having been perceived as prominently atomistic, were condemned by the contemporaries above all because of the theological (...) implications of their provocative anti-Aristotelism. Alchemy itself was not directly implicated in the case of the theses. On the contrary, the theses were perceived as an alien body within the alchemical tradition. (shrink)

ArgumentHistorians have accorded a privileged status to the analytic ideal of elements as a distinctive marker of “modern” chemistry. Boyle’s and Lavoisier’s have been used to characterize their modernity, which has in turn justified their status as the founding fathers of modern chemistry. It has been difficult, however, to establish a viable connection between these two fathers or the genealogy of their definitions. I argue in this paper that French didactic tradition gave rise to the definition Boyle stated in the (...) Sceptical Chymist, or the analytic/philosophical ideal of elements. He did not endorse the definition he gave, but criticized its lack of analytic rigor and philosophical sophistication. His critique served as a negative heuristic, leading to Nicolas Lemery’s analytic ideal of “chemical principles” as distinct from “natural principles.” Lemery’s definition survived in French didactic tradition, as is evidenced in Macquer’s and Guyton’s textbooks which provided direct precedents for Lavoisier’s analytic ideal of “elements or principles.”.

Le tournant du XVIIe au XVIIIe siècle est une période décisive pour l’histoire de la chimie qui passe de la reconnaissance institutionnelle à la contestation de son fondement théorique, pour apparaître au final comme la seule partie de la Physique à pouvoir prétendre atteindre la « vérité certaine ». Ce qui se joue alors n’est rien de moins que la redéfinition de ses principes, à savoir son socle de vérités sur lequel s’appuie la science chimique. Cette période est en fait (...) la dernière étape de l’évolution du rapport entre les deux dimensions – théorique et pratique – dans lesquelles se déploie la chimie, qui a vu, par le développement de l’usage des principes dits seconds, l’ensemble des principes chimiques entrainé vers un réalisme empirique, ayant pour effet d’ôter de la chimie toute cohérence théorique. Aussi l’apparition du mécanisme – pas plus celui de Boyle – n’est-il en réalité responsable du bouleversement que connaît la chimie ; elle n’est pas davantage responsable de sa régénération au tout début du XVIIIe siècle. La conscience de la faiblesse théorique de la chimie va devenir pour elle promesse de vigueur théorique sur la base de ce qui représente sa force : l’expérience. À la suite de la perte de ce qui fut certitude, le chimiste devient un être à ré-instruire. Un chimiste tel que Samuel Cottereau Du Clos illustre parfaitement le passage d’une science chimique comme connaissance des principes à une chimie comme science cette fois du vraisemblable. (shrink)

Van Helmont's chemistry and medicine played a prominent part in the seventeenth-century opposition to Aristotelian natural philosophy and to Galenic medicine. Helmontian works, which rapidly achieved great notoriety all over Europe, gave rise to the most influential version of the chemical philosophy. Helmontian terms such as Archeus, Gas and Alkahest all became part of the accepted vocabulary of seventeenth-century science and medicine.

William Newman construes the Scientific Revolution as a change in matter theory, from a hylomorphic, Aristotelian to a corpuscular, mechanical one. He sees Robert Boyle as making a major contribution to that change by way of his corpuscular chemistry. In this article it is argued that it is seriously misleading to identify what was scientific about the Scientific Revolution in terms of a change in theories of the ultimate structure of matter. Boyle showed, especially in his pneumatics, how empirically accessible, (...) intermediate causes, as opposed to ultimate, mechanical ones can be explored and identified by experiment. Newman is right to observe that Boyle constantly sought intimate links between chemistry and the mechanical philosophy. However, by doing so he did not thereby significantly aid the cause of attaining experimental knowledge of chemical phenomena and the support that Boyle’s chemistry provided for the mechanical philosophy was weaker than both Boyle and Newman imply. Boyle was intent on articulating and defending a strict, mechanical account of the ultimate structure of matter to be sure, but his contributions to the new experimental science in general, and chemistry in particular, are best seen as distinct from that endeavour.Keywords: Chemistry; Mechanical philosophy; Corpuscular philosophy; Experiment; Robert Boyle; William Newman.

This dissertation deals with the alchemical activities of the English natural philosopher Robert Boyle . ;The study begins by setting down a consistent and defensible terminology for discussing a period during which time the words alchemy and chemistry were synonymous. A review of the three centuries of secondary literature on Boyle then reveals how his image has been successively reformed and tailored to fit prevailing apologetic or historiographic programmes, almost always with the effect of modernizing him and his interests and (...) further burying his already obscure alchemical interests. A radically new interpretation of the Sceptical Chymist is then presented, developed by a newly rigorous reading of the work--together with its 1680 appendix--in terms of its context and sources, and with a much more nuanced appreciation of the competing schools of seventeenth century "chymistry." The work is thus revealed as not critical of the aims or methods of traditional alchemical masters, or adepti, but rather of the "unphilosophical" practice of Paracelsian pharmacists and the systematizing of textbook writers. Boyle's own positive view of transmutational alchemy is then unambiguously presented by a consideration of his "lost" Dialogue on the Transmutation and Melioration of Metals now reconstructed from scattered surviving fragments and presented here in full for the first time. The text shows Boyle's unflinching belief in the reality of the Philosophers' Stone and its powers, and his dissatisfaction with those who denied it. Different kinds of transmutation within traditional alchemy are described, alongside evidence for Boyle's maintenance of these traditional divisions. Boyle's own witness of transmutation is then recounted along with his attempts to contact adepti, thus involving him in a diverse array of social and scientific networks across Europe. ;Boyle's alchemical programme is next detailed, including his reading and writing of alchemical texts, his adoption of alchemical means of communication , and his experimental attempts to prepare alchemical arcana. In this last regard, his forty-year search for the Philosophical Mercury and its correct manipulation is chronicled. Finally, Boyle's motivations are explored. Boyle's interest in chrysoppoeia was not fueled primarily by the promise of medicines, gold, or new natural philosophical knowledge devolving from the Stone, but rather by his belief that the Stone could function as a medium for facilitating communication with angels and other spirits. As such, it could potentially manifest spirit activity and thus act as a powerful weapon against atheism. ;This study reveals Boyle as much less of a modern and revolutionary than presentist, positivist, heroic, or even the new sociological schools would have him. Rather, he is here resituated in a complex web of contemporary questions and currents of thought, and involved in the debate of an important question of the day. Alchemy was a chief concern of Robert Boyle and as such it must be fully integrated into our portrayal of him, and by extension, of his time--a critical period in the development of modern science as a whole, and of early modern chemistry in particular. The spiritual functions with which Boyle eventually endowed alchemy promoted it to a central position in his thought as a whole, functioning then as a middle term mediating between his two chief missions--the advancement of natural philosophy and the defense and propagation of Christianity.
