This book represents an original journey beginning from the simple and undifferentiated atom, to differentiated atoms, to molecules, to macromolecules, and to the thresholds of life. One of the most important aims of this book is to underline the philosophical function of the concept of molecule. The description of the material world permitted by the concept of structured entity has revolutionized the entire scientific worldview. Moreover, the concept of macromolecule has projected the molecular world towards the threshold of the biological (...) world and this analysis will also form an integral part of this book. The scientific and epistemological approach towards the molecular world will also serve to link chemistry with philosophy proper. Up to the 19th century, chemistry had enjoyed its own philosophical foundation, which was anchored in the concept of atom, a concept with a rich philosophical heritage. The 20th century appropriation of this concept by physicists has deprived chemistry of its distinctive philosophical foundation, relegating it being merely an applied branch of physics. In this regard, we consider the concept of molecular structure as an exquisitely philosophical concept and as the strong point permitting a solid differentiation of chemistry from physics. The recuperation of a fertile relationship between chemistry and philosophy can and must occur around the concept of structured and complex reality. Chemistry can be projected to the cultural vanguard but only if its practitioners once again attend to the conceptual and philosophical concerns within their discipline, albeit without abandoning the technical concerns that are essential to modern science.

This paper aims to develop an account of the pursuitworthiness of models based on a view of models as epistemic tools. This paper is motivated by the historical question of why, in the 1960s, when many scientists hardly found QSAR models attractive, some pharmaceutical scientists pursued Quantitative Structure–Activity Relationship (QSAR) models despite the lack of potential for theoretical development or empirical success. This paper addresses this question by focusing on how models perform their heuristic functions as epistemic tools rather than (...) as potential theories. I argue that models perform their heuristic function by “constructing” phenomena from data in the sense that they allow the model users who interact with the medium of the models to recognise the phenomena as such. The constructed phenomena assist model users in identifying which conditional hypotheses that are focused on low-level regularities concerning entities such as chemical compounds are more “testworthy,” a concept that links the costs associated with hypothesis testing with the fertility of the hypothesis.

The article summarizes the software tool on astrophysical analysis with multi-wavelength space telescope data. It recaps the evidence analysis conducted on the Kerr-Newman black hole (KNBH). It was written prior to the article Research on the Kerr-Newman Black Hole in M82 Confirms Black Hole and White Hole Juxtapose not soon after the experiment. The conducted analysis suggested Hawking radiation is caused by the movement of ergosurfaces of the BH and serves as the primal evidence for black hole and white hole (...) juxtapose. A later data exploration was conducted with the radiation trails in the multi-wavelength data. The evidences produced corroborates with Yale professor Priyamvada Natarajan's black hole seeds theory. It implies that the electromagnetic dynamic of fusion and fission temperature determines the pressure of surface tension on the macro particles, and the mass density of the BH is determined by the electromagnetic tension between the outer ergosurface and inner ergosurface. The ring singularity of the BH and the Penrose-Hawking singularity of the BH determine the spin and gravitational singularity of the BH. Inside the ergosurfaces, the BH singularities' backward inflow causes the vicinity's rate on feeding the BH. It makes the active galactic nuclei (AGN) a semi-closed system. The density pressure is released on threshold. During the mass exchange observed by energy momentum upon the AGN's open, the macroparticle composition of the BH changes with the galactic event. This causes the expansion rate of the galaxy and contraction rate of the BH. AGN types and their relative motions determine the expansion rate of the cosmic universe in a generalized quantitative thinking. The article concludes that BH spin is caused by the asymmetric motions of AGN in the BH system. A set of the nuclear resonance caused by BH and white hole (WH) oscillation is processed with the same set of data. (shrink)

In this paper, we try to understand how Bunge’s scientific hylorealism can fit with several crystal chemistry’s objects and their properties. It is found that many of them, lying at the very core of this discipline, bring support to ontologi-cal emergentism. Building units, such as vacancies, their chemical potential, the crystal quantum number and many aspects of the spectroscopic properties of 4f electrons in ionic crystals, are presented as striking examples of emergent (or submergent) objects or properties encountered in the (...) single crystalline state. Among all the types of building. (shrink)

Chemistry is at the crossroads of many issues in philosophy of science. It entertains intimate relations with both physics and biology; it incorporates strong theoretical elements mixed with sophisticated experimental practices; it is linked with industry, medicine and agriculture, which makes the discipline central for many societal issues. Yet surprisingly, despite a recent resurgence of interest, the field has not received as much attention from philosophers as other disciplines such as physics and biology. Philosophie de la chimie purports to fill (...) this gap by presenting the French-speaking audience with a collection of historical and contemporary texts from historians, chemists and philosophers examining the nature of chemistry and its specificities and highlighting its original philosophical importance.

This book examines the way in which Robert Boyle seeks to accommodate his complex chemical philosophy within the framework of a mechanistic theory of matter. More specifically, the book proposes that Boyle regards chemical qualities as properties that emerged from the mechanistic structure of chymical atoms. Within Boyle’s chemical ontology, chymical atoms are structured concretions of particles that Boyle regards as chemically elementary entities, that is, as chemical wholes that resist experimental analysis. Although this interpretation of Boyle’s chemical philosophy has (...) already been suggested by other Boyle scholars, the present book provides a sustained philosophical argument to demonstrate that, for Boyle, chemical properties are dispositional, relational, emergent, and supervenient properties. This argument is strengthened by a detailed mereological analysis of Boylean chymical atoms that establishes the kind of theory of wholes and parts that is most consistent with an emergentist conception of chemical properties. The emergentist position that is being attributed to Boyle supports his view that chemical reactions resist direct explanation in terms of the mechanistic properties of fundamental particles, as well as his position regarding the scientific autonomy of chymistry from mechanics and physics.

“It is probably justified in requiring a transformation of the image of the real world as it has been constructed in the last 300 years… [for] now it seems to work no longer. One must therefore go back 300 years and reflect on how one could have proceeded differently at that time, and how the whole subsequent development would then be modified. No wonder that puts us into boundless confusion!” :: a letter from Schrödinger to Einstein in 1950 -/- The (...) theme of the new book, Idols of the Mind vs True Reality by Bhakti Madhava Puri, Ph.D. is concerned with the clear exposition of the pivotal conceptions and misconceptions of Galileo’s and others’ ideas that produced the subsequent development of what would become modern mathematized science. -/- The confusions and almost complete ignorance that exist today regarding something so fundamental as consciousness is immediately cleared up when the obvious errors are seen in the ad hoc presumptions of the original founders of modern science who were blindsided by the metaphysical ontologies that held sway during their lives, but to which we no longer adhere, thanks to the development of philosophy beyond that period. We trace this progress out in a concise way in the book. -/- The modern mind, thanks to science education, is focused on the one-sided empirical approach to knowledge by sensuous perception, but this fails to account for the role of subjective cognition or conception – the role of consciousness in such perceptions. This artificial separation of the original unity-in-difference between conception and content has been rendered impossible to broach because of the historical metaphysical tradition of dualism firmly held by the fathers of modern science such as Galileo and Descartes. -/- The presumed impossible gap between subject and object is bridged once we realize that the object is what the subject knows it to be. This does not reduce the object to the subject as the abstract idealists (monists) naively are only too hasty to presume as an immediate identity (oneness). Mediation is involved; there are both difference and identity at play. It is merely lazy un-thinking that ignores the intricate dynamic in the mediating activity that is the heart and life of consciousness. The main purpose of the book is to restore the central importance of the conceptual moment that is integral to science and which makes it truly worthy of the name Science or scientific knowledge.

Some experiments are risky in that they cannot repeatedly produce certain phenomenon at will for study because the scientific knowledge of the process generating the uncertain phenomenon is poorly understood or may directly contradict with existing scientific knowledge. These experiments may have great impact not just to the scientific community but to mankind in general. Banning them from study may incur societies a great opportunity cost but accepting them runs the risk that scientists are doing junk science. How to make (...) an informed decision to accept/reject such study scientifically for the mainstream scientific community is of great importance to mankind. Here, we propose a statistical methodology to handle the situation. Specifically, we consider the likelihood of not observing the phenomenon after n trails so that it is statistically significant to have nil result. Consequently, we reject the hypothesis that there is some probability that we observe the phenomenon. (shrink)

The aim of this article is to present a different perspective through which to examine reduction and emergence; namely, the perspective of chemistry’s relation to physics.

Following Kripke and Putnam, the received view of chemical kinds has been a microstructuralist one. To be a microstructuralist about chemical kinds is to think that membership in said kinds is conferred by microstructural properties. Recently, the received microstructuralist view has been elaborated and defended, but it has also been attacked on the basis of complexities, both chemical and ontological. Here, I look at which complexities really challenge the microstructuralist view; at how the view itself might be made more complicated (...) in order to accommodate such challenges; and finally, at what this increasingly complicated picture implies for our standard assessment of chemical kindhood—primarily, for the widespread assumption that chemical kinds in general are more neat and tidy than those messy biological ones. _1_ The Received View _2_ A Taxonomy of Chemical Kinds _3_ Atomic Number _4_ H2O, H3O+, OH−, and More _5_ Complicating the Microstructuralist Picture _6_ Concrete and Other Mixtures _7_ Macromolecules, Especially Proteins _8_ Abandoning Sameness of Elemental Composition _9_ Not So Different after All.

I critically examine Stewart’s suggestion that we should weigh the various predictions Mendeleev made differently. I argue that in his effort to justify discounting the weight of some of Mendeleev’s failures, Stewart invokes a principle that will, in turn, reduce the weight of some of the successful predictions Mendeleev made. So Stewart’s strategy will not necessarily lead to a net gain in Mendeleev’s favor.

SUMMARYEighteenth-century scientific translation was not just a linguistic or intellectual affair. It included numerous material aspects requiring a social organization to marshal the indispensable human and non-human actors. Paratexts and actors' correspondences provide a good observatory to get information about aspects such as shipments and routes, processes of translation and language acquisition, texts acquisition and dissemination.The nature of scientific translation changed in France during the second half of the eighteenth century. Beside solitary translators, it also happened to become a collective (...) enterprise, dedicated to providing abridgements or enriching the learned journals with full translations of the most recent foreign texts. That new trend clearly had a decisive influence on the nature of the scientific press itself. A way to set up science as a social activity in the provincial capital of Dijon, translation required a local and international network for acquiring the linguistic and scientific expertise, along with the original texts, as quickly as possible. Laboratory results and mineralogical observations were used to compare material facts with those described in the original text. By providing a double kind of validation – with both the experiments and the translations – the laboratory thus happened to play a major role in translation. (shrink)

A short overview, written for a primarily scientific audience, of how conceptual analysis and philosophy of science can assist in nanoscience research.

How can a work of art give us clues about scientific aspects? How can chemistry help a painter enhance his creativity and, above all, preserve the original characteristics of his work? Does an artist require scientific knowledge to innovate or, at least, not to be faked? Other symbiotic fields between art and science are: tattoos, as body art with physical and chemical consequences; pigments, as basic materials with interesting historiographical preparations; spectroscopy diagnosis, as very broad and thorough method of analysis (...) ; biosensors, as one of the applications of new pigments. Note also the interconnection between the several possible paths of science and art, which reflect new challenges with enormous potential investigated through a literature review and the application as a case study in an educational inquiry module.

This edited volume of 13 new essays aims to turn past discussions of natural kinds on their head. Instead of presenting a metaphysical view of kinds based largely on an unempirical vantage point, it pursues questions of kindedness which take the use of kinds and activities of kinding in practice as significant in the articulation of them as kinds. The book brings philosophical study of current and historical episodes and case studies from various scientific disciplines to bear on natural kinds (...) as traditionally conceived of within metaphysics. Focusing on these practices reveals the different knowledge-producing activities of kinding and processes involved in natural kind use, generation, and discovery. -/- Specialists in their field, the esteemed group of contributors use diverse empirically responsive approaches to explore the nature of kindhood. This groundbreaking volume presents detailed case studies that exemplify kinding in use. Newly written for this volume, each chapter engages with the activities of kinding across a variety of disciplines. Chapter topics include the nature of kinds, kindhood, kinding, and kind-making in linguistics, chemical classification, neuroscience, gene and protein classification, colour theory in applied mathematics, homology in comparative biology, sex and gender identity theory, memory research, race, extended cognition, symbolic algebra, cartography, and geographic information science. -/- The volume seeks to open up an as-yet unexplored area within the emerging field of philosophy of science in practice, and constitutes a valuable addition to the disciplines of philosophy and history of science, technology, engineering, and mathematics. -/- Contributions from a diverse group of established and junior scholars in the fields of Philosophy and History and Philosophy of Science including Hasok Chang, Jordi Cat, Sally Haslanger, Joyce C. Havstad, Catherine Kendig, Bernhard Nickel, Josipa Petrunic, Samuli Pöyhönen, Thomas A. C. Reydon, Quayshawn Spencer, Jackie Sullivan, Michael Wheeler, and Rasmus Grønfeldt Winther. (shrink)

We report the results of a phenomenographic analysis of faculty beliefs about the purposes for teaching upper-division physical chemistry courses in the undergraduate curriculum. A purposeful sampling strategy was used to recruit a diverse group of faculty for interviews. Collectively, the participating faculty regularly teach or have taught physical chemistry courses in 16 different chemistry departments in the United States. While faculty agreed that the goal of teaching physical chemistry was to help students develop robust conceptual knowledge of the subject (...) matter within thermodynamics, statistical mechanics, quantum mechanics, spectroscopy, chemical kinetics, and other major topics, some articulated strong beliefs about epistemic and social learning goals. An understanding of the relations between different ways of thinking about teaching upper-division physical chemistry courses offers practitioners with alternative perspectives that may help them expand their awareness of the purposes for teaching physical chemistry in the undergraduate curriculum. Furthermore, knowledge of faculty beliefs about their teaching provides educational researchers and curriculum developers with an understanding about the potential opportunities or barriers for helping faculty align their beliefs and goals for teaching with research-based instructional strategies. We discuss our findings with the intention to expand faculty awareness of the discourse on physical chemistry education to include various perspectives of the purpose for teaching upper-division physical chemistry courses.

This is an attempt to take a look at chemistry from the point of view of practical realism. Besides its social–historical and normative aspects, the latter involves a direct reference to experimental research. According to Edward Caldin chemistry depends on our being able to isolate pure substances with reproducible properties. Thus, the very basis of chemistry is practical. Even the laws of chemistry are not stable but are subject to correction. At the same time, these statements do not necessarily make (...) Edward Caldin a predecessor of practical realism. The latter has other predecessors, like Rom Harré’s policy realism or Sami Pihlström’s pragmatic realism. Chemistry is an experimental science. The experiment is a purposeful and critically theory-guided constructive, manipulative, material interference with nature according to Rein Vihalemm, the founder of practical realism. Chemistry is physics-like science but just partly so. This is an important point in the context of the current paper. (shrink)

Invited review of the anthology of new papers _Philosophy of Chemistry: Growth of a New Discipline_.

Ideograms have great communicative value. They refer to concepts in a simple manner, easing the understanding of related ideas. Moreover, ideograms can simplify the often cumbersome notation used in the fields of Physics and physical Chemistry. Nonetheless only a few ideograms—like \ and Å—have been defined to date. In this work we propose that the scientific community follows the example of Mathematics—as well as that of oriental languages—and bestows a more important role upon ideograms. To support this thesis we propose (...) ideograms for essential concepts in Physics and Chemistry. They are designed to be intuitive, and their goal is to make equations easier to read and understand. Our symbols are included in a publicly available package. (shrink)

The philosophy of chemistry has emerged in recent years as a new and autonomous field within the Anglo-American philosophical tradition. With the development of this new discipline, Eric Scerri and Grant Fisher's "Essays in the Philosophy of Chemistry" is a timely and definitive guide to all current thought in this field. This edited volume will serve to map out the distinctive features of the field and its connections to the philosophies of the natural sciences and general philosophy of science more (...) broadly. It will be a reference for students and professional alike. Both the philosophy of chemistry and philosophies of scientific practice alike reflect the splitting of analytical and continental scholastic traditions, and some philosophers are turning for inspiration from the familiar resources of analytical philosophy to influences from the continental tradition and pragmatism. While philosophy of chemistry is practiced very much within the familiar analytical tradition, it is also capable of trail-blazing new philosophical approaches. In such a way, the seemingly disparate disciplines such as the "hard sciences" and philosophy become much more linked. (shrink)

Mathematics is so common-place in modern physics and chemistry that one may not realise how controversial its admittance was to these fields in the eightieth and ninetieth centuries respectively. This paper deals with the controversy during the formation of physical chemistry as a discipline in the late ninetieth and early twentieth centuries and sketches more recent criticisms of the way mathematics has been used in solution chemistry. The controversy initially related particularly to electrolyte chemistry and its emerging use of mathematics (...) to support Arrhenius’ theory of ionic dissociation. The impact of mathematics on the field is divided into three phases: that from 1880 to 1920 which was a period of heightened controversy; that from 1920 to 1990 which was a period of relative calm and mathematical development; and finally, that from 1990 to the present which has been a time of reflective criticism of the extensive use of empirical parameters in the emergent mathematics of the twentieth century. It is argued that the current solution to the criticism, as proposed by Heyrovska, is best viewed in the light of the historical development of the controversy. (shrink)

Professor Rudolph A. Marcus, recipient of the 1992 Nobel Prize in Chemistry, is a distinguished theoretical chemist. Two important theories happen to bear his name: the Rice Ramsperger Kassel Marcus theory of unimolecular reactions and the Marcus theory of electron transfer reactions. When considering Marcus’ work, one finds characteristics of it that bear striking similarity to those that can be found in the work of some famous scientists. Such characteristics appear then as common recurring patterns in the work of theoreticians. (...) Among them we find the following: the creation of new theories, driven by experiments that preceding theories were unable to explain; the use of thought experiments; the generalization and extensions from one realm of science to another; the making of predictions and the finding of new properties from correlations among series of data; the use of variational principles; the providing of different demonstrations of an equation; the introduction of new types of coordinates; the innovative capacity to use, by somehow recreating it under the pressure of the physical problem, a mathematical method previously unknown to the author; and finally, the presentation of formulations of the same theory in different mathematical and physical languages. Before discussing in some detail the above points, a brief description of Marcus’ work is first presented for the convenience of the reader. (shrink)

In introductory chemistry courses, should students be encouraged to solve problems by reasoning based on conceptual understanding or by applying memorized facts and algorithms? Cognitive scientists have recently studied this issue with the assistance of new technologies. In the current consensus model for cognition, during problem solving the brain relies on “working memory” to sequentially process small elements of knowledge. Working memory is able to hold and manipulate virtually all elements that can be recalled “with automaticity” from long-term memory, but (...) very few elements that are not recallable. As one consequence, students can reliably solve well-structured science problems only if most of the facts and algorithms needed to solve the problem have previously been well memorized. To achieve automaticity in recall, facts and procedures must be committed to memory and then tagged with associations to other knowledge in the brain’s conceptual frameworks. Accommodation can be assisted by guided inquiry. Articles citing methods that can assist students in the development of automaticity are listed, and implications for chemistry instruction are discussed. (shrink)

The very existence of explicit techno-scientific controversies in the “nano” arena is often denied on behalf of a conception of science, risks, public engagement and responsibility which borders on a disembodied idealism and merits at least serious discussion. The recurrence of this view prompted us to clarify our position regarding our common field of research, in order to avoid being trapped in the seemingly clear divide between the universal and neutral pursuit of pure science, on the one hand, and on (...) the other hand the infinite variety of values and opinions that lead to the horrors throes of pure relativism. We therefore launched an internal trans-disciplinary project, in order to overhaul the premises underpinning both this idealistic standpoint and our own work, and to find a better definition of our approach to the exploration of the real policy implications of NST research initiatives. Indeed, the debates surrounding NST clearly have wider implications for the examination of issues of Science, Technology and Society as a whole. A first step in this clarification process was taken in Paris, at the conference which has now been published in this issue of Foundations of Chemistry. We further develop it in this paper, in the hope that it will contribute to the joint construction of a better nano-future. (shrink)

This paper aims to connect philosophy of chemistry, green chemistry, and moral philosophy. We first characterize chemistry by underlining how chemists: co-define chemical bodies, operations, and transformations; always refer to active and context-sensitive bodies to explain the reactions under study; and develop strategies that require and intertwine with a molecular whole, its parts, and the surroundings at the same time within an explanation. We will then point out how green chemists are transforming their current activities in order to act upon (...) the world without jeopardizing life. This part will allow us to highlight that green chemistry follows the three aforementioned characteristics while including the world as a partner, as well as biodegradability and sustainability concerns, into chemical practices. In the third part of this paper, we will show how moral philosophy can help green chemists: identify the consequentialist assumptions that ground their reasoning; and widen the scope of their ethical considerations by integrating the notion of care and that of vulnerability into their arguments. In the fourth part of the paper, we will emphasize how, in return, this investigation could help philosophers querying consequentialism as soon as the consequences of chemical activities over the world are taken into account. Furthermore, we will point out how the philosophy of chemistry provides philosophers with new arguments concerning the key debate about the ‘intrinsic value’ of life, ecosystems and the Earth, in environmental ethics. To conclude, we will highlight how mesology, that is to say the study of ‘milieux’, and the concept of ‘ecumeme’ proposed by the philosopher and geographer Augustin Berque, could become important both for green chemists and moral philosophers in order to investigate our relationships with the Earth.

RESUMO Neste artigo pretendo identificar um "estilo de raciocínio" próprio à química e apontar a disseminação de seus produtos e conceitos. O objetivo é o de explicitar alguns elementos que caracterizam o estilo de pensar e de fazer da química na segunda metade do século XVIII, sua capilarização técnico-cultural. O delineamento de um estilo químico de raciocinar origina-se da constância dos espaços técnico-epistêmicos em que o saber químico é construído. A química é uma ciência de laboratório, eminentemente técnica e operatória, (...) quer dizer, trata-se de um conhecimento técnico-científico stricto sensu. Produtora de artefatos, a ciência química é inseparável da técnica, da tecnologia e da indústria, de maneira que sua identidade epistêmica é indissociável de sua história. Seu estilo caracteriza um valor profundo na cultura técnica do homo faber, do poder de agir sobre a natureza e de transformá-la através de manipulações e de rearranjos. ABSTRACT In this paper I will identify a "style of reasoning" that is proper to to Chemistry and to point to the dissemination of its products and concepts. My aim is to explain some elements that characterize the style of thinking and engaging in Chemistry in the second half of the 18th century, its techno-cultural capillary action. The shaping of a chemical style of reasoning originated from the constancy of the techno-epistemic sites in which chemical knowledge is formed. Chemistry is a laboratory science, eminently technical and operative, i.e., it deals with a techno-scientific knowledge stricto sensu. A producer of artifacts, chemical science is inseparable from technique, technology and industry, in such a way that its epistemic identity is inseparable from its history. Its style marks a profound value in the technical culture of the homo faber, the power of acting upon nature and transforming it through manipulations and rearrangements. (shrink)

On the basis of this description I explore from the perspective of Critical Discourse Analysis the discursive strategies employed by the producers of (...) these texts to legitimize the ideology of progress and the new identities it involves. In consonance with the aims of CDA, the purpose of this paper is to promote a critical awareness among those who are assigned subaltern positions as passive interpreters of these texts and those who – often inadvertently – play key roles in institutions that participate in the reproduction and legitimization of hegemonic discourses.

Book Review of Manuel DeLanda: Philosophical Chemistry: Genealogy of a Scientific Field, London 2015.

Chemistry, especially its historical practice, has in the philosophy of science in recent decades attracted more and more attention, influencing the turn from the vision of science as a timeless logic-centred system of statements towards the history- and practice-centred approach. The problem of pluralism in science has become a popular topic in that context. Hasok Chang’s “active normative epistemic pluralism” manifested in his book Is water H2O? Evidence, realism and pluralism, pursuing an integrated study of history and philosophy of science, (...) has provoked quite a widespread debate. It provides a good opportunity to discuss the topical philosophical issue of the nature of disagreements. The differences among disagreements in different domains have been pointed out in the disagreement literature. It has been noticed that in mathematics and science consensus is established more clearly than in philosophy where it remains largely unachievable. However, this conclusion is derived in the context of traditional logic-centred view of science. The aim of this paper is to consider the different nature of disagreements in science and in philosophy in the context of the history- and practice-centred approach. The analysis is focused on the critique of the received view of the Chemical Revolution which played quite a central role in Chang’s becoming a pluralist about science. Unlike Chang, however, a modified Kuhnian paradigm-conception of science and scientific revolutions is defended. (shrink)

This paper argues for the theoretical and practical validity of similarity as a useful epistemological tool in scientific knowledge generation, specifically in chemistry. Classical analyses of similarity in philosophy of science do not account for the concept’s practical significance in scientific activities. We recur to examples from chemistry to counter the claim of authors like Quine or Goodman to the effect that similarity must be excluded from scientific practices . In conclusion we argue that more recent conceptualizations of the notion (...) of similarity, particularly Giere’s one, are appropriate for a philosophical analysis that considers scientific practices on equal terms with scientific theory.

Chemistry deserves more philosophical attention not so much to do justice to a long-neglected science or to enhance its cultural prestige, but to undermine a number of taken-for-granted assumptions about scientific rationality and more importantly to diversify our metaphysical views of nature and reality. In brief, this paper does not make the case for a philosophy of chemistry. It rather urges philosophers of science to listen to chemists and discuss what they learn from them. Because over the course of many (...) centuries chemists have developed a special access to nature and a special way of investigating and dealing with material substances, they have confronted a number of epistemological and ontological issues that are worth discussing. Following critical remarks about the disciplinary partition of philosophy, a historical section presents the contributions to philosophy of a few French twentieth-century chemists-turned philosophers to emphasize how they have challenged the dominant philosophical categories. The final section develops one of the lessons that philosophers can learn from chemists: to pay attention to things, to their materiality and activity in order to develop new ontological perspectives.

"Brower explores the way philosophers were inspired by entomological social systems and communication to reflect on human psyche, social behavior, community organization, communication, and inter-individual relationships. His essay rehearses the swarms of insects embedded in contemporary philosophy and literary theory, not only showing how many of the major concepts (or philosophemes) in continental philosophy – sexuality, politics, thinking, time, interdependence, and language – draw lessons from the world of insects, but also illustrating again how the insect world spurred human reflection.".

Besides the presentation and conclusions, the chapter is divided into two equally important sections. The first one describes the modern development of atomic and molecular structure, emphasising some of the philosophical problems that have been taken, and those that have to be faced in its understanding. The second discusses the alternative conceptions and difficulties of students of different educational levels and also the different approaches to its historical or philosophical teaching. Finally, we recognise the necessity for science teachers to assume (...) a specific historical-philosophical position. (shrink)

Philosophers have paid far less attention to chemistry than they have to physics. It is only in the last twenty years or so that the philosophy of chemistry has gained an important place in the philosophy of science. However, before then, there have been important exceptions to the neglect of chemistry. Notably, chemistry has been very important in the French tradition: Bernadette Bensaude-Vincent has argued that the attention that Pierre Duhem, Emile Meyerson, Hélène Metzger and Gaston Bachelard paid to chemistry (...) had a profound impact on their philosophies, which as a consequence share concerns and views of science, despite their differences. She has maintained in particular that the controversy around the role of Lavoisier in the history of chemistry ‘drew attention to the scientific revolutions’. (shrink)

This chapter utilises scholarship in philosophy of biology and philosophy of chemistry to produce meaningful implications for biology and chemistry education. The primary purpose for studying philosophical literature is to identify different perspectives on the nature of laws and explanations within these disciplines. The goal is not to resolve ongoing debates about the nature of laws and explanations but to consider their multiple forms and purposes in ways that promote deep and practical understanding of biological and chemical knowledge in educational (...) contexts. Most studies on the nature of science in science education tend to focus on general features of scientific knowledge and underemphasise disciplinary nuances. The authors aim to contribute to science education research by focusing on the characterisations of laws and explanations in biology and chemistry in the philosophical literature and illustrating how the typical coverage of biology and chemistry textbooks does not problematise meta-perspectives on the nature of laws and explanations. The chapter concludes with suggestions for making science teaching, learning and curriculum more inclusive of the epistemological dimensions of biology and chemistry. (shrink)

Panenmentalist possibilities are individual pure possibilities existing independently of any mind, actual reality, and possible-world conception. These possibilities are a priori accessible to our intellect and imagination. In this paper, I attempt to shed some panenmentalist light on the discovery of chemical branched chain reactions and its implications on biology and cancer research. I also examine the case of the Belousov–Zhabotinsky reaction which, at first, was believed to be impossible. Finally, I proceed to examine through a panenmentalist lens Szilard’s discovery (...) of the possibility of physical chain reactions and Mullis’s discovery of a polymerase chain reaction. All these major actual discoveries clearly depend on the discovery of the relevant panenmentalist possibilities and the ways in which they relate to one another. (shrink)

The article presents a conceptually unified, quantitative account of the development of chemical phenomena throughout the cosmic history, with a detailed discussion of the cosmological, astrophysical, geological, biological, and anthropological context. The totality of cosmic chemistry is represented by a list of 176 classes of phenomena, drawn from the Universal Decimal Classification library cataloguing system, and divided into 6 phases: of no chemistry, of prestellar chemistry, of galactic chemistry, of planetary chemistry, of biological chemistry, of human history. These are separated (...) by periods of intensive chemical innovation, likened to phase changes based on four similarities: the rapidity of change, its intensity, the presence of nucleation-like dynamics, and dependence of outcome on history. The limitations and perspectives of the method are described, including the extension of the analysis to all 893 UDC classes relevant to the study of nature. The role of chemical phenomena in the general architecture of the universe is shortly discussed, especially their complex relationships with basic phenomena described by physics. (shrink)
