Of all the traditional sciences it is alchemy based as it is in metallurgy that is directly concerned with the coming of the industrial order. In alchemical terms modern man lives in the Ferric Age and his state is best analogized to the properties of the metal iron, hard, cold, unbending but quick to succumb to corrosion and rust. The great ancient wisdom traditions of the world all anticipated this present age for it was already implicit in the technological (...) and other changes that brought on the dawn of history. These ancient traditions - dismissed as childish superstitions by the scientist contain ideas essential to the self-understanding that contemporary man so desperately needs. This is the central contention of the writings brought together in Primordial Alchemy & Modern Religion. Drawing upon many unexpected sources especially Plato and the ancient Greeks these wide-ranging, generous essays provide timely reiterations of ancient alchemical traditions and trace some pivotal themes that have continued in the theology and symbolism of the modern religions. This work restores some important keys for the recovery of a lost heritage of primordial wisdom, offering fresh perspectives on aspects of the Western and Islamic alchemical traditions in particular, and at the same time exploring the most distant roots of the modern impasse.

The landscape of seventeenth-century chemistry is complex, and it is impossible to find in it either a clear-cut distinction between alchemy and chemistry or a sort of simple identification of the two. The seventeenth-century cultural context contained a rich variety of "chemical" discourses with arguments ranging from specific experiments to the justification of the validity of chemistry and its novelty in terms of its extraordinary antiquity. On the basis of an analysis of the works by O. Borch, J.J. Glauber, (...) and J. J. Becher, this paper tries to demonstrate that a historical reconstruction of "chemistry" must consider these different levels of the chemical debate. Only then will it be possible to appreciate the outstanding role played by G.E. Stahl in founding modern chemistry. The paper argues in favor of a contextualization of the historical research on seventeenth-century chemistry. (shrink)

ABSTRACT Early modern alchemy studied both matter and life, much like today's life sciences. What material life is and how it comes about intrigued alchemists. Many found the answer by assuming a vital principle that served as the source and cause of life. Recent literature has presented important cases in which vitalist formulations incorporated corpuscular or mechanical elements that were characteristic of the New Science and other cases in which vitalist thinking influenced important figures of the Scientific Revolution. Not (...) merely speculative, vitalist ideas also motivated chymical practice. The unity of life science and material science that is found in many formulations of Renaissance alchemy disintegrated in Georg Ernst Stahl's version of post-Cartesian vitalism. (shrink)

This article turns one of most cited philosopher's John Dewey's title, How We Think (1933/1998) back upon itself to consider how ‘thought’ or ‘reason’ are cultural practices that historically order and generate principles for reflection and action. The discussion proceeds thusly: (1) Schooling is about changing people; (2) Changing people embodies cultural theses about modes of living, such as that of being a lifelong learner or a Learning Society. The modes of living in modern pedagogy embody changing cultural norms and (...) values about systems of reason that are to express universal cosmopolitan qualities; (3) Pedagogy fabricates the systems of reason to principles for reflection and participation that shreds provincial values in the name of greater universal cosmopolitan values; (4) This ‘making’ of cosmopolitan ‘reason’ forms through cultural practices that have overlapping sets of distinctions and differentiations about agency, the rational planning of one's biography in time, and science as a procedure for action in daily life. The educational sciences and philosophy of education are inscription devices or intellectual tools in the governing practices; (5) The inscriptions of reason, however, are more than mere qualities of thought or the mind. The narratives and images of cosmopolitan reason embody particular sublimes about collective hopes, desires and fears; (6) Further, the distinctions of cosmopolitan reason are comparative in that the very qualities of the ‘reasonable person’ create maps of its opposite: those who do not ‘fit’ the normalized qualities of the cosmopolitan thus stand outside that mode of living; The last section (7) provides three exemplars of the changing notions of the cosmopolitan and its ‘other’ in school subjects (literacy, mathematics, and music). School subjects are viewed as alchemies that transmogrify disciplinary thinking into normalizing pedagogies that fabricate who the child is and should be. The historical sketch has two layers in its educational study. One is to explore the politics of schooling with cosmopolitanism as a comparative method to consider the changing cultural practices that fabricate who child is and should be. The second raises questions about taken‐for‐granted categories and their systems of reason of education and reform. The very categories and distinctions of policy, educational research and philosophy are historicized as cultural practices to order, classify and divide what is ‘seen’ and felt as experience.

Alchemy is central to Jung's hypothesis of the collective unconscious. In this volume he begins with an outline of the process and aims of psychotherapy, and then moves on to work out the analogies between alchemy, Christian dogma and symbolism and his own understanding of the analytic process. Introducing the basic concepts of alchemy, Jung reminds us of the dual nature of alchemy, comprising both the chemical process and a parallel mystical component. He also discusses the (...) seemingly deliberate mystification of the alchemists. Finally, in using the alchemical process as providing insights into individuation, Jung emphasises the importance of alchemy in relating to us the transcendent nature of the psyche. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 42.1 (2004) 104-105 [Access article in PDF] William R. Newman and Lawrence M. Principe. Alchemy Tried in the Fire: Starkey, Boyle, and the Fate of Helmontian Chymistry. Chicago: University of Chicago Press, 2002. Pp. xv + 344. Cloth, $40.00. Newman and Principe have produced a masterful study of intellectual context, primarily by correcting the commonly held belief that there was a radical (...) break in the seventeenth century between late medieval alchemy and early modern chemistry. Although their main focus is on George Starkey (the 'alchemist') and Robert Boyle (the 'chemist'), they also provide copious details on the chemical practices and theories of Van Helmont, Benjamin Worsley, Frederick Clodius, and Kenelm Digby, among others. It is hard to do justice to their complex study in a short review. Following a brief summary, therefore, I will limit my discussion to how the authors' conclusions are significant for a more in-depth and nuanced understanding of philosophy in the seventeenth century.After a helpful introduction, Chapter 1 outlines the differences in the early lives of the English, aristocratic Boyle and the American, Harvard-educated Starkey. Chapter 2's background on late medieval chemistry includes an examination of corpuscular theories within that tradition as well as Van Helmont's arguments concerning the way in which mathematics is useful for explaining "superficial" changes but not the real, internal changes in bodies. Chapters 3 and 4 provide a close study of Starkey's laboratory notebooks. Among the entries, recorded in a style adapted from Scholasticism, there are passages that adopt the secrecy of alchemy, while others show Starkey's effective use of theoretical principles and such experimental quantitative methods as mass balance. Chapter 5 examines Boyle's intellectual context. Newman and Principe argue convincingly for Starkey's role in Boyle's addition of Helmontian elements to the general Baconian program. Chapter 6 looks at the [End Page 104] results of Boyle's eclectic mix of chemistry and mechanism. Although Helmontian chemistry played a significant role in Boyle's natural philosophy, the authors attribute his meager interest in quantitative measures and analyses to his attempts to use chemistry as a support for mechanism and as evidence against Aristotelianism. The concluding chapter draws together elements from previous chapters to provide the full argument against the idea of a radical break between medieval alchemy and modern chemistry.Newman and Principe's reconsideration of traditional categories surrounding the idea of a radical break should provide an impetus for similar reconsideration in the history of philosophy. As they point out, 'the' mechanical philosophy drew from a diverse range of disciplines. Boyle's eclectic and complex attempt to develop a unique version of the mechanical philosophy can be seen in other English philosophers, especially Locke and Newton. This study provides a promising basis for yet more extensive and refined studies of the seventeenth-century milieu. The continuing over-emphasis on the physical principles of Descartes and Gassendi's versions of the mechanical philosophy and the tendency to reduce all mechanism to their view needs revision. Also in need of reconsideration is the currently popular belief that the study of context simply means adding social elements to an uncontroversial intellectual context. As the authors clearly show, much more work on the intellectual context remains to be done.One line of research in the history of philosophy that could be pursued concerns the role of Francis Bacon in this context. Although Newman and Principe mention the general Baconian ethos, a detailed discussion of Bacon was clearly beyond their scope. Yet Bacon's own debts to chemistry, although frequently unrecognized, seem more significant given this study. Also, it would be interesting to see the extent to which Bacon's works influenced Van Helmont or Starkey. Newman and Principe's claims regarding the novelty of Starkey's notebooks, for example, may be a little overstated. Many of the elements from Starkey's notebooks can be found in Bacon's advice in his Natural and Experimental Histories (1622). In that work, Bacon advised writers... (shrink)

Albertus Magnus’ alchemy is a subject that has attracted the attention of the scholars since the early decades of the 20th century. Yet, the research that has been conducted this far is characterised by its non philosophical character. As a matter of fact, the previous studies approached Albertus’ alchemy either in terms of history of science or of intellectual history. In this paper, I focus on Albertus’ definition of alchemical transmutation that is found in his De mineralibus and (...) I analyze it in terms of his theory of creation and of his theory of matter. Therefore, I show whether a re-creation of a metal is in accordance with Albertus’ philosophy and congruently I bring forth the Aristotle Graecus and the Aristotle Latinus that are found as background in his alchemical theory of transmutation. Ultimately this paper aims to show that the aforementioned theory is not an arbitrary statement from Albertus’ part, but the result of a serious philosophical endeavour. (shrink)

This paper studies the English poems of Richard Crashaw from a historicist and formalist perspective. It specifically considers Crashaw’s poetry in its religious but also intellectual and early scien­tific context to investigate the frequently overlooked influence of science on his poetry. Metaphors drawn from alchemy and particularly from the trans­formation of matter to achieve its purification and spiritualisation enrich the poet’s expression of mystical devotion to underline that access to the spiritual as well as mystical union with Christ are (...) deeply rooted in the devotee’s body. Representations of the earth as a chemical laboratory focus on materiality and corporality to emphasise the constant movement animating matter. A form of spiritual alchemy underscores Crashaw’s Christocentrism and references to the metamorphoses of matter consistently aim to express mystical union. A meta-poetic analysis eventually highlights a significant analogy between reading and alchemical processes in order to demonstrate the anagogical aim of Crashaw’s verse and the way his poems work on his reader’s heart to lift his soul. References to liquefaction, distillation or sublimation echo the published works of mystics but alchemical conceits based on symbolically evocative topoï and polysemic vocabulary reinforce the importance of the corporal in the expe­rience of mystical union.

This essay takes its point of departure from a post-Nietzschean reading of Kant and the limits of logic and critique. The focus is on science, particularly chemistry and alchemy via mercurial cinnabar (HgS), to this day the primary source of elemental mercury. Seeking to raise the question of science as Nietzsche names it along with the question of truth, this essay undertakes to raise the question of historiography in science, using the illustration of alchemy.

Jon Elster has written a comprehensive, wide-ranging book on the emotions in which he considers the full range of theoretical approaches. Drawing on history, literature, philosophy and psychology, Elster presents a complete account of the role of the emotions in human behaviour. While acknowledging the importance of neurophysiology and laboratory experiment for the study of emotions, Elster argues that the serious student of the emotions can learn more from the great thinkers and writers of the past, from Aristotle to Jane (...) Austen. He attaches particular importance to the work of the French moralists, notably La Rochefoucauld, who demonstrated the way esteem and self-esteem shape human motivation. The book also maintains a running dialogue with economists and rational-choice theorists. Combining methodological and theoretical arguments with empirical case-studies and written with Elster's customary verve and economy, this book has great cross-disciplinary appeal. (shrink)

ABSTRACT Alchemy now holds an important place in the history of science. Its current status contrasts with its former exile as a “pseudoscience” or worse and results from several rehabilitative steps carried out by scholars who made closer, less programmatic, and more innovative studies of the documentary sources. Interestingly, alchemy's outcast status was created in the eighteenth century and perpetuated thereafter in part for strategic and polemical reasons—and not only on account of a lack of historical understanding. (...) class='Hi'>Alchemy's return to the fold of the history of science highlights important features about the development of science and our changing understanding of it. (shrink)

This book explores politics as a form of alchemy, understood as the transformation of entities through an alteration of their identities. Identifying this process as a common denominator of many political phenomena, such as communism, EU integration, mediatisation or globalisation, the author demonstrates not only the widespread presence of alchemical techniques in politics, but also the acceleration of their deployment. A study of the steady growth of power as it reaches a continuous and permanent stage, thus avoiding the inherent (...) difficulties connected with birth and death of political organisations and institutions, this volume reveals political alchemy to be a form of self-sustaining growth through sterile multiplication, devoid of meaning. Revealing both the integrative and disintegrative nature of a political process that, while appearing to work in the interests of all, in fact produces apathy, desperate mobilisation and despair by crushing concrete entities such as personality and tradition, Political Alchemy: Technology Unbounded will appeal to scholars of sociology and anthropology with interests in social theory and political thought.

For nearly a century, the worldwide anthroposophical movement has been a catalyst for environmental activism, helping to bring to life many modern ecological practices such as organic farming, community-supported agriculture, and green banking. Yet the spiritual practice of anthroposophy remains unknown to most environmentalists. A historical and ethnographic study of the environmental movement, Eco-Alchemy uncovers for the first time the profound influences of anthroposophy and its founder, Rudolf Steiner, whose holistic worldview, rooted in esoteric spirituality, inspired the movement. Dan (...) McKanan shows that environmentalism is itself a complex ecosystem and that it would not be as diverse or transformative without the contributions of anthroposophy"--Provided by publisher.

As the primary ingredient in gunpowder, saltpeter was an extraordinarily important commodity in the early modern world. Historians of science and technology have long studied its military applications but have rarely focused on its uses outside of warfare. Due to its potential effectiveness as a fertilizer, saltpeter was also an integral component of experimental agricultural reform movements in the early modern period and particularly in seventeenth-century England. This became possible for several reasons: the creation of a thriving domestic saltpeter production (...) industry in the second half of the sixteenth century; the development of vitalist alchemical theories that sought a unified explanation for the “growth” of minerals, metals, and plants; the rise of experimental natural philosophy; and the mid-seventeenth-century dominance of the English East India Company in the saltpeter trade, which allowed agricultural reformers to repurpose domestically produced saltpeter in agriculturally productive ways. This paper argues that the Hartlib Circle – a loose network of natural philosophers and social reformers – adopted vitalist matter theories and the practical, experimental techniques of alchemists to transform agriculture into a more productive enterprise. Though their grandiose plans never came to fruition, their experimental trials to develop artificial fertilizers played an early role in the origins and development of saline chemistry, agronomy, and the British Agricultural Revolution.

The phenomenon of "social alchemy", containing the idea of the possibility of creating a new man and a new world and passing through all radical thought, especially of the New and Modern times, had and has a habit of pouring out into violence, in the broadest sense of the word, — from the guillotine and concentration camps to modern "information colonization of consciousness". Having received technological support, when digital technologies and new communication systems cover almost the entire world community, (...) leaving no one outside of their comprehensive influence, the phenomenon of "social alchemy" has acquired a qualitatively different, special and global significance. At the same time, the goals, means and actors have changed, only its radical component has remained unchanged, striving to transform society and build such social, political and economic structures and relations, that would correspond to certain ideas of some elites (economic, political, intellectual) about what should the global world be like in order to ensure their interests to the greatest extent.

Ecological science has been viewed by some philosophers as a foundational resource for the development of metaphysical, epistemological and normative views concerning humanity’s relationship with the natural environment, or what might be called an “ecological philosophy.” Analysis of three attempts to infer philosophical conclusions from ecological science shows that (1) there are serious obstacles facing any attempt to derive unique philosophical consequences from ecological science and (2) the project of developing an ecological philosophy relevant to human-environment relations is seriously hindered (...) by a reliance on traditional ecological science that focuses on relations between nonhuman organisms and their environments. However, the search for an ecological philosophy is not inherently misguided because (1) although ecological science may never support a unique philosophical interpretation of ecological theory, empirical evidence can function to narrow the range of possible interpretations, which is a significant epistemic achievement; and because (2) there are several non-traditional branches of ecological science that focus on human-environment relations and that consequently may be better suited to function as conceptual resources for the sorts of problems that concern environmental philosophers.

Alchemy is the art of transforming base metals into precious ones, usually silver and/or gold. The most important method conceived to reach this goal was the creation of the elixir, also called the philosophers’ stone, which, applied to the prime-matter, would lead to an accelerated process of ripening of metals, eventually ending in gold. How did Arabo-Islamic alchemists suppose that the transmutation worked? What were the conditions the adept had to fulfil in order to succeed? And what did they (...) think would happen when one finally has created the philosophers’ stone? Will the economy collapse because gold and silver will lose their validity? Will the alchemist simply lean back and enjoy? Or will the world end, because man has finally attained the knowledge that should be God’s only? (shrink)

The Renaissance of scientific thought in twelfth-century Western culture, when alchemy was introduced into the Latin schools, was largely due to the wave of translations, mainly from Arabic into Latin, but also including translations into and from Hebrew, sometimes with vernacular languages as intermediaries. Alchemy, whose tradition had been broken in the West at the end of the Hellenistic age, gained considerable attention—albeit less than astronomy/astrology and medicine—from the twelfth-century translators, who presented Latin culture with a hitherto unknown (...) doctrine that was completely different from any other science. Alchemy, as the Latin Middle Ages received it, is the philosophical search for the agent of material perfection by means of the manipulation of base materials. It thereby united theory and practice in a way unexpected by Latin scholars. In fact, alchemy as a doctrine was inseparable from laboratory practice; and this practice so much resembled well-established craftsmen's labor that for a long period the place of alchemy in the divisio disciplinarum wavered between the mechanical and the liberal arts.

In recent years there has been an explosion of interest by companies in developing approaches to instill values in their decision‐making processes and to manage and report on their social performance. The emerging field of social and ethical accounting, auditing and reporting (SEAAR) is characterised by considerable differentiation not only in terminology, but also in methodology and focus. This article aims to analyse the key conceptual and methodological differences between internally focussed approaches to SEAAR, dealing with ethics (behavioural) issues, and (...) externally focussed approaches to SEAAR, dealing with social (stakeholder) issues. In their discussion of the benefits and potential pitfalls of exclusively internally or externally focussed approaches the authors suggest two organisational metaphors as heuristics – the Cultish and the Chameleon organisation. The authors then propose an integrative approach to SEAAR which will overcome this dissonance and initiate a mutually reinforcing process that, in the long‐term, can build both internal trust and cohesiveness and external credibility. The suggested approach is characterised as social and ethical alchemy since the aim is to achieve more than the sum of the two separate parts – a business ethics programme and a social reporting process – by creating leverage and synergy between the key components.

In its heyday alchemy was a comprehensive theory of transmutation describing not only transformations of base into precious metals but also transformations of the soul up and down the great chain of being. Alchemy was not just a physics but also a metaphysics. Alchemy as metaphysics attracts interest to this day, as in Carl Jung's writings about the soul and personal identity. As he noted, "The alchemists sought for that effect which would heal not only the disharmonies (...) of the physical world but inner psychic conflict as well, the 'affliction of the soul,' and they called this effect the lapis philosophorum [i.e., the philosopher's stone]. In order to obtain it, they had to loosen the age-old attachment of the soul to the body and thus make conscious the conflict between the purely natural and the spiritual man.". (shrink)

This article studies a new fantasy subgenre that emerged in contemporary China, xiuzhen xiaoshuo (immortality cultivation fiction), which builds imaginary worlds around the magical practice of Chinese alchemy and fuses it with science and technology. After the arrival of the modern, Western triad of science, religion, and magic/superstition, alchemical practices of the Daoist tradition were labeled as a “superstition” to be eradicated; however, they persisted and began to flourish within and beyond the realm of fantasy literature in the late (...) twentieth and early twenty‐first centuries. Immortality cultivation fiction has generated a magical form of transhumanism, which envisions human enhancement through techniques beyond the boundaries of “proper” science and “legitimate” religion. While transhumanism in the Euro‐American West is popular among white bourgeoisie males and dominated by tendencies to reaffirm the human subject constructed by excluding the various subhuman others, magical transhumanism in Chinese fantasy explores the possibility of transcending that antagonistic relationship and making a posthuman subject and a utopian world.

At some point during the last two years of his life, Robert Boyle dictated to his friend, Gilbert Burnet, Bishop of Salisbury, some notes on major events and themes in his career. Some of the information he divulged in these memoranda has become quite widely known because Burnet used it in the funeral sermon for Boyle that he delivered a month after his death, at St Martin's in the Fields on 7 January 1692. In addition, these notes were cited several (...) times by Thomas Birch in the ‘Life of the Honourable Robert Boyle’ that he prefixed to his edition of Boyle's collected works of 1744: he there describes his source as ‘Mr.Boyle'smemorandums of his own life, dictated by himself to BishopBurnet’.2 What has hitherto been virtually overlooked is that the manuscript of these notes, which is in Burnet's hand, survives among the Birch Papers in the British Library: it is this document—and particularly a substantial component of it which was publicized by neither Burnet nor Birch—that forms the starting point for this paper.

Historians have long seen Sir William Petty’s ‘political arithmetic’ as an important contribution to the early social sciences, applying mathematics to the analysis of political and especially economic questions. A closer look at Petty’s political arithmetic manuscripts reveals, however, his political preoccupation with ‘transmuting the Irish into English’ by state manipulation of demography. Large-scale, coerced ‘counter-transplantations’ of ‘exchanges of women’ between England and Ireland would facilitate the ‘proportionable mixture’ and ultimately the ‘union’ of the two populations, stabilizing the turbulent politics (...) of late Stuart Ireland and securing English colonial government there. This paper explores Petty’s use of alchemical concepts in his transmutative political arithmetic, and argues that the idiom of alchemy was essential to Petty’s conception of politics and his solution to the problem of governing culturally distinct colonial populations. It makes a preliminary attempt to identify some of Petty’s likely sources among seventeenth-century proponents of corpuscularian, mechanical accounts of chemical change. Finally, it suggests that the influence of alchemy on the shape of early social-scientific thought may have been more significant than was previously realized.Keywords: Political arithmetic; Alchemy; William Petty; Ireland; Political economy.
