The periodic table of the elements is one of the most powerful icons in science: a single document that captures the essence of chemistry in an elegant pattern. Indeed, nothing quite like it exists in biology or physics, or any other branch of science, for that matter. One sees periodic tables everywhere: in industrial labs, workshops, academic labs, and of course, lecture halls. It is sometimes said that chemistry has no deep ideas, unlike physics, which can boast quantum mechanics and (...) relativity, and biology, which has produced the theory of evolution. This view is mistaken, however, since there are in fact two big ideas in chemistry. They are chemical periodicity and chemical bonding, and they are deeply interconnected. The observation that certain elements prefer to combine with specific kinds of elements prompted early chemists to classify the elements in tables of chemical affinity. Later these tables would lead, somewhat indirectly, to the discovery of the periodic system, perhaps the biggest idea in the whole of chemistry. Indeed, periodic tables arose partly through the attempts by Dimitri Mendeleev and numerous others to make sense of the way in which particular elements enter into chemical bonding. (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 Philosophy of Chemistry" is a timely and definitive guide to all current thought in this field. One of the themes of this collection is how philosophy of chemistry can make a contributions to problems of philosophy more generally, such as how chemistry and quantum chemistry contribute (...) to the philosophy of the mind.

The debate about the relative epistemic weights carried in favour of a theory by predictions of new phenomena as opposed to accommodations of already known phenomena has a long history. We readdress the issue through a detailed re-examination of a particular historical case that has often been discussed in connection with it—that of Mendeleev and the prediction by his periodic law of the three ‘new’ elements, gallium, scandium and germanium. We find little support for the standard story that these predictive (...) successes were outstandingly important in the success of Mendeleev's scheme. Accommodations played an equal role—notably that of argon, the first of the ‘noble gases’ to be discovered; and the methodological situation in this chemical example turns out to be in interesting ways different from that in other cases—invariably from physics—that have been discussed in this connection. The historical episode when accurately analysed provides support for a different account of the relative weight of prediction and accommodation—one that is further articulated here. (shrink)

The historical development of the electronic configuration model is traced and the status of the model with respect to quantum mechanics is examined. The successes and problems raised by the model are explored, particularly in chemical ab initio calculations. The relevance of these issues to whether chemistry has been reduced to quantum mechanics is discussed, as are some general notions on reduction.

Differing views on reduction are briefly reviewed and a suggestion is made for a working definition of 'approximate reduction'. Ab initio studies in quantum chemistry are then considered, including the issues of convergence and error bounds. This includes an examination of the classic studies on CH2 and the recent work on the Si2C molecule. I conclude that chemistry has not even been approximately reduced.

The article concerns five traditionally difficult issues that chemical educators encounter and how they should be resolved. In some cases I propose the examination of necessary and sufficient conditions in order to cast light on the relationships under discussion. The five educational issues are, the notion that a pH value of seven implies a neutral solution of water and vice versa, the use of Le Châtelier’s Principle, the relative occupation and ionization of 4s and 3d orbitals, the explanation of anomalous (...) electronic configurations and the elements that make up group 3 of the periodic table.

The article begins with a response to a recent contribution by Jensen, in which he has criticized several aspects of the use of triads of elements, including Döbereiner’s original introduction of the concept and the modern use of atomic number triads by some authors including myself. Such triads are groups of three elements, one of which has approximately the average atomic weight of the other two elements, as well as having intermediate chemical reactivity. I also examine Jensen’s attempted reconstruction Mendeleev’s (...) use of triads in predicting the atomic weights of three hitherto unknown elements, that were subsequently named gallium, germanium and scandium. The present article then considers the use of atomic number triads, in conjunction with the phenomenon of first member anomaly, in order to offer support for Janet’s left-step periodic table, in which helium is relocated into group 2 of the table. Such a table features triads in which the 2nd and third elements of each group, without fail, fall into periods of equal length, a feature that is absent in the conventional 18-column or the conventional 32-column table. The dual sense of the term element, which is the source of much discussion in the philosophy of chemistry, is alluded to in further support of such a relocation of helium that may at first appear to contradict chemical intuition.

The main thrust of the paper involves a theoretical and philosophical analysis of the claim made in September 1999 that atomic orbitals have been directly imaged for the first time. After a brief account of the recent claims the paper reviews the development of the orbit and later orbital concepts and analyzes the theoretical status of atomic orbitals. The conclusion is that contrary to these claims, atomic orbitals have not in fact been observed. The non-referring nature of modern atomic orbitals (...) is discussed in the context of Laudan's writings on realism, the success of theories, and whether or not scientific terms refer. I conclude that the failure to observe orbitals is a good prima facie case for divorcing the success of theories from the question of whether their central terms refer. The added relevance of this case is that it concerns a current and highly successful theory. Finally, the relevance of this 'floating model' to contemporary discussions on scientific models is briefly considered. (shrink)

A chronological approach that examines the progression of Levinas's deliberations on time over six decades, thus providing new insights about aspects of Levinasian thought that have consistently troubled readers, including the differences between Levinas's early and later writings, his controversial invocation of the feminine, and the blurry line between philosophy and religion in his work"--Provided by publisher.

The article examines a recent interventionist account of causation by Ross, in which electronic configurations of atoms are considered to be the cause of chemical behavior. More specifically I respond to the claim that a change in electronic configuration of an atom, such as occurs in the artificial synthesis of elements, causes a change in the behavior of the atom in question. I argue that chemical behavior is governed as much by the nuclear charge of an atom as it is (...) by its electronic structure. It is suggested that an adequate analysis requires attention to the dynamical interactions between nuclear charges and those of electrons, as typically carried out through the application of the Schrödinger equation. It is concluded that electronic configurations can only be said be causal in a weak sense that is somewhat analogous to the causal arguments that are invoked in folk physics. (shrink)

Political philosophical work on whistleblowing has thus far neglected the role of journalists. A curious oversight, given that the whistleblower’s objective - informing the public about government wrongdoing - can typically not be realized without the media. The present article, therefore, aims to start remedying this neglect by exploring some of the most pressing questions. Accordingly, the paper will be structured as follows: Section 1 will explain why the authorities have treated whistleblowers far more harshly than the journalists who publish (...) their disclosures. Still, the freedom of expression of media workers is less extensive than that of ordinary individuals. Section 2 will explain why by arguing that the freedom of expression of the press, contrary to that of individuals, is not an unconditional good; instead, it is good merely instrumentally. Section 3 considers and refutes an argument for a more expansive press freedom based on the marketplace of ideas model and, in doing so, also discusses some important differences between the ethics of the traditional and the new online media. Often journalists, like whistleblowers, will justify their publications based on leaked classified documents by appealing to the public interest. Yet, this is problematic for two reasons: the public interest is never clarified; and this argument overlooks the fact that the public interest can also be a reason for not publishing about leaked classified documents, even if the leaks are verified. Accordingly, Section 5 sets out to clarify the public interest. Section 4 then discusses two case studies – one concerning unverified leaks, and one concerning verified leaks – in order to demonstrate how we might employ the concept of the public interest in order to determine the permissibility of publishing about leaked classified information in practice.

This book brings together a collection of essays written by scholars inspired by Eugene Gendlin's work, particularly those interested in thinking with and beyond Gendlin for the sake of a global community facing significant crises. The contributors take inspiration from Gendlin's philosophy of the implicit, and his theoretical approach to psychology. The essays engage with Gendlin's ideas for our era, including critiques and corrections as well as extrapolations of his work. Gendlin himself worried that knowing about a problem is too (...) often conflated with actions that might lead to change; the essays in this book point to a form of understanding that is activated, an embodied and immediate way of thinking about today's problems. Throughout the volume, the contributors creatively engage with Gendlin's work and its applicability to the complex, pressing crises of our time: the Covid-19 pandemic, environmental/climate issues, racism, sexism, economic inequality, and other factors threatening human persons and communities. Gendlin's theoretical approach to psychology is naturally interdisciplinary, making this book an essential read for anyone interested in moving to the boundaries where psychology meets philosophy, theology, art, environmental studies, science, and technology, and much more.

Although the periodic system of elements is central to the study of chemistry and has been influential in the development of quantum theory and quantum mechanics, its study has been largely neglected in philosophy of science. The present article is a detailed criticism of one notable exception, an attempt by Hettema and Kuipers to axiomatize the periodic table and to discuss the reduction of chemistry in this context.

Although research has examined factors influencing understanding of informed consent in biomedical and forensic research, less is known about participants' attention to details in consent documents in psychological survey research. The present study used a randomized experimental design and found the majority of participants were unable to recall information from the consent form in both in-person and online formats. Participants were also relatively poor at recognizing important aspects of the consent form including risks to participants and confidentiality procedures. Memory effects (...) and individual difference characteristics also appeared to influence recall and recognition of consent form information. (shrink)

I claim that the question of whether chemistry is reduced to quantum mechanics is more ambiguous and multi-faceted than generally supposed. For example, chemistry appears to be both reduced and not reduced at the same time depending on the perspective that one adopts. Similarly, I argue that some conceptual issues in quantum mechanics are ambiguous and can only be laid to rest by embracing paradox and ambiguity rather than regarding them as obstacles to be overcome. Recent work in the reduction (...) of chemistry is also reviewed, including discussions of the ontological reduction of chemistry and the question of the emergence of chemistry from physics.

For a period of several years the philosopher of science Hasok Chang has promoted various inter-related views including pluralism, pragmatism, and an associated view of natural kinds. He has also argued for what he calls the persistence of everyday terms in the scientific view. Chang claims that terms like phlogiston were never truly abandoned but became transformed into different concepts that remain useful. On the other hand, Chang argues that some scientific terms such as acidity have suffered a form of (...) “rupture”, especially in the case of the modern Lewis definition of acids. Chang also complains that the degree of acidity of a Lewis acid cannot be measured using a pH meter and seems to regard this as a serious problem. The present paper examines some of these views, especially what Chang claims to be a rupture in the definition of acidity. It is suggested that there has been no such rupture but a genuine generalization, on moving from the Brønsted-Lowry theory to the Lewis theory of acidity. It will be shown how the quantification and measurement of Lewis acidity can easily be realized through the use of equilibrium theory and the use of stability constants. (shrink)

It is commonly stated, by both whistleblower protection laws and political philosophers, that a breach of state secrecy by disclosing classified documents is justified if it serves the public interest. The problem with this defense of justified whistleblowing, however, is that the operative term – the public interest – is all too often left unclarified. This is problematic, because it leaves potential whistleblowers without sufficient certainty that their disclosures will be covered by the defense, leading many to err on the (...) side of caution and remain silent, depriving the public of much-needed information. Failing an agreed upon definition of the public interest or a process to determine it, judges’ applications of the public interest in whistleblowing cases have been criticized for demonstrating ‘judicial idiosyncrasy’. The present paper, therefore, sets out to provide some clarity concerning the concept of the public interest, and to ascertain the extent to which a public interest defense for whistleblowing is feasible and desirable.

The article discusses some of Heinz Post's views on correspondence and whether revolutions occur in science a la Kuhn. For example Post points out that the periodic table of the chemical elements has withstood any revolutions. Specific issues examined include the Paneth-Fajans controversy, the extent to which quantum mechanics provides an explanation for the periodic table and ab initio calculations in quantum chemistry.

This article carefully analyzes a recent paper by Weisberg in which it is claimed that when Mendeleev discovered the periodic table he was not working as a modeler but instead as a theorist. I argue that Weisberg is mistaken in several respects and that the periodic table should be regarded as a classification, not as a theory. In the second part of the article an attempt is made to elevate the status of classifications by suggesting that they provide a form (...) of ‘side-ways explanation’. (shrink)

ABSTRACTIn scholarship on intellectual property, nonconsequentialist justifications for IP rights seem to suffer from one of two flaws. To some, such justifications seem indeterminate; they seem not to offer concrete guidance about how rights should be structured in practice. To others, such justifications seem dogmatic; they seem to mandate certain conclusions without letting decision makers consider the relevant context or consequences of different proposals to regulate IP. Both impressions neglect an important dimension of reasoning about rights—practical reason. In perfectionist theories (...) of law, ‘practical reason’ describes the principles by which general justifications for rights are implemented in specific decisions in politics and ethics. This article introduces practical reason to IP scholarship, and it shows how practical reason facilitates reasoning about the design of different legal IP rights.

We investigated whether regret predicted the motivation to act heroically. In a series of studies, we examined the relationship between regret, search for meaning in life, and heroism motivation. First, Study 1 (a and b) established the link between regret and search for meaning in life, considering regret as a whole, action regret, and inaction regret. Specifically, regret correlated positively with search for meaning in life. In additional two studies, we examined whether regret predicted the heroism motivation and whether this (...) effect would be mediated through search for meaning in life. Study 2 confirmed this hypothesis for individual differences in regret, using a correlational design. Study 3 confirmed the hypothesis for temporary experiences of regret, using an experimental design. In addition, in Study 3 we found that heroism motivation was more likely for people with high self-enhancement needs than for those with lower self-enhancement needs. We discuss the relationship between regret and heroism in light of these results and explore implications for everyday life. (shrink)

In his latest book, Eric Scerri presents a completely original account of the nature of scientific progress. It consists of a holistic and unified approach in which science is seen as a living and evolving single organism. Instead of scientific revolutions featuring exceptionally gifted individuals, Scerri argues that the "little people" contribute as much as the "heroes" of science. To do this he examines seven case studies of virtually unknown chemists and physicists in the early 20th century quest to (...) discover the structure of the atom. They include the amateur scientist Anton van den Broek who pioneered the notion of atomic number as well as Edmund Stoner a then physics graduate student who provided the seed for Pauli's Exclusion Principle. Another case is the physicist John Nicholson who is virtually unknown and yet was the first to propose the notion of quantization of angular momentum that was soon put to good use by Niels Bohr. Instead of focusing on the logic and rationality of science, Scerri elevates the role of trial and error and multiple discovery and moves beyond the notion of scientific developments being right or wrong. While criticizing Thomas Kuhn's notion of scientific revolutions he agrees with Kuhn that science is not drawn towards an external truth but is rather driven from within. The book will enliven the long-standing debate on the nature of science, which has increasingly shied away from the big question of "what is science?". (shrink)

This book demonstrates the importance of a duty-based approach to morality. The dominance of what has been labeled “rights talk” leads to the neglect of duties without corresponding rights and stimulates the proliferation of questionable human rights. Therefore, this book argues for a duty-based perspective on morality in order to, first, salvage duties of virtue, and, second, counter the trend of rights-proliferation by providing some conceptual clarity concerning rights and duties that will enable us to differentiate between genuine and spurious (...) rights-claims. The argument for this duty-based perspective is made by examining two particularly contentious duties: duties to aid the global poor and civic duties. These two duties serve as case studies and are explored from the perspectives of political theory, jurisprudence and moral philosophy. The argument is made that both these duties can only be adequately defined and allocated if we adopt the perspective of duties, as the predominant perspective of rights either does not recognize them to be duties at all or else leaves their content and allocation indefinite. This renewed focus on duties does not wish to diminish the importance of rights. Rather, the duty-based perspective on morality will strengthen human rights discourse by distinguishing more strictly between genuine and inauthentic rights. Furthermore, a duty-based approach enriches our moral landscape by recognizing both duties of justice and duties of virtue. The latter duties are not less important or supererogatory, but function as indispensable complements to the duties prescribed by justice. In this perceptive and exceptionally lucid book, Eric Boot argues that a duty-focused approach to morality will remedy the shortcomings he finds in the standard accounts of human rights. The study tackles staple philosophical topics such as the contrasts between duties of virtue and duties of justice and imperfect and perfect obligations. But more importantly perhaps, it also confronts the practical question of what our human rights duties are and how we ought to act on them. Boot's book is a splendid example of how philosophy can engage and clarify real world problems.

Natural Property Rights presents a novel theory of property based on individual, pre-political rights. The book argues that a just system of property protects people's rights to use resources and also orders those rights consistent with natural law and the public welfare. Drawing on influential property theorists such as Grotius, Locke, Blackstone, and early American statesmen and judges, as well as recent work in in normative and analytical philosophy, the book shows how natural rights guide political and legal reasoning about (...) property law. It examines how natural rights justify the most familiar institutions in property, including public property, ownership, the system of estates and future interests, leases, servitudes, mortgages, police regulation, and eminent domain. Thought-provoking and comprehensive, the book challenges leading contemporary justifications for property and shows how property both secures individual freedom and serves the common good. (shrink)

The article disputes the recent claim featured in "Nature" magazine and many other science magazines to the effect that atomic orbitals have been observed for the first time. The claim is incorrect in view of the unconvincing nature of the evidence adduced and since atomic orbitals are deemed unobservable in principle by quantum mechanics. In addition, the possible educational drawbacks of this incorrect claim are discussed.

Geckos have gained ecological access to novel microhabitats by exploiting intermolecular van der Waals forces, which allow them to climb smooth vertical surfaces. They use microscopic surface‐based phenomena to thrive in a macroscopic mass‐ and kinetic energy‐based world. Here we detail this as a premier example of integrative biology, spanning seven orders of magnitude and a lot of interesting biology. Emergent properties arising from molecular adhesion include several adaptive radiations that have produced a great diversity of geckos worldwide.

The chemical nature of element 72, subsequently named hafnium, is generally regarded as a prediction from Bohr's theory of the periodic system and hence as a prediction from quantum theory. It is argued that both of these views and in particular the latter are mistaken. The claim in favour of Bohr's theory is weakened by his accommodation of independent chemical arguments and the claim in favour of quantum theory is untenable since the prediction is not strictly deductive.

This commentary provides a critical examination of a recent article by Allen and Knight in which the authors claim to provide the long-sought explanation for the Madelung, or n + ℓ, n rule for the order of orbital filling in many-electron atoms. It is concluded that the explanation is inadequate for several reasons.

In this article, Severson explores the insights of Emmanuel Levinas regarding theodicy and the problem of evil. Levinas considers philosophical and practical justifications of suffering to be blasphemous, violating the sanctity of the suffering of the other person, even when well-meant. Severson introduces distinctions between “pain” and “suffering” to extrapolate and explain Levinas’s striking rejection of theodicy.

Eric Hedin was enjoying a productive career as a physics professor at Ball State University when the letter from a militant atheist arrived and all hell broke loose. The conflict spilled first onto the pages of the local newspaper, and then into the national news. The atheist attack included threats from the Freedom from Religion Foundation, which targeted Hedin after learning his Boundaries of Science course exposed students to an evidence-based case for design and purpose in cosmology, physics, and (...) biochemistry. Canceled Science tells the dramatic story of the atheist campaign to cancel Hedin's course, reveals the evidence the atheists tried to bury, and explores discoveries that have revolutionized our understanding of the nature and origin of matter, space, and even time itself.

Abstract. The science and religion discourse in the Western academy, though expansive, has not paid significant enough attention to South Asian views, particularly those from Hindu thought. This essay seeks to address this issue in three parts. First, I present the South Asian standpoint as it currently relates to the science and religion discourse. Second, I survey and evaluate some available literature on South Asian approaches to the science and religion discourse. Finally, I promote three possible steps forward: (1) the (...) literature must shift from high Hindu philosophical religion to the more prevalent bhakti traditions, (2) the Indian context must be understood in its own right without metaphysical assumptions attached to the concepts of science and religion, and (3) most importantly, concepts unique to the Indian worldview, such as dharma, maya, and cit, must receive better treatment in translation in order to facilitate a more accurate exchange of ideas across cultural boundaries.

As ecologically and socially oriented food initiatives proliferate, the significance of these initiatives with respect to conventional food systems remains unclear. This paper addresses the transformative potential of alternative food networks by drawing on insights from recent research on food and embodiment, diverse food economies, and more-than-human food geographies. I identify several synergies between these literatures, including an emphasis on the pedagogic capacities of AFNs; the role of the researcher; and the analytical and political value of using assemblage and actor-network (...) thinking to understand the far-reaching forces and power disparities confronting proponents of more ethical and sustainable food futures.
