The main scientific problems of chemical bonding were solved half a century ago, but adequate philosophical understanding of chemical combination is yet to be achieved. Chemists routinely use important terms ("element," "atom," "molecule," "substance") with more than one meaning. This can lead to misunderstandings. Eliminativists claim that what seems to be a baseball breaking a window is merely the action of "atoms, acting in concert." They argue that statues, baseballs, and similar macroscopic things "do not exist." When macroscopic objects like (...) baseballs move, exceedingly large numbers (1025) of microscopic components coordinate their activities. Understanding how this happens requires attention to the interactions that link parts into larger units. Eliminativists say that everything that truly exists has causal relationships in addition to those of its components—"nonredundant causality." This paper holds that if a number of entities interact in such a way that the effect of that collection on test objects is different than it would have been in the absence of the interaction, then identification of that collection as a single composite agent is warranted, for purposes to which that difference is relevant. Ordinary "chemical substances" (both elementary materials such as dihydrogen and compounds such as water) fulfill this version of the requirement of nonredundant causality. Other sorts of chemical coherences, including chemical dissipative structures (e.g., flames), also fulfill that criterion. All these types of coherences qualify as "substances" (as that term is used in philosophy) even though they are not all "chemical substances.". (shrink)

What, precisely, is `salt'? It is a certainwhite, solid, crystalline, material, alsocalled sodium chloride. Does any of that solidwhite stuff exist in the sea? – Clearly not.One can make salt from sea water easily enough,but that fact does not establish thatsalt, as such, is present in brine. (Paper andink can be made into a novel – but no novelactually exists in a stack of blank paper witha vial of ink close by.) When salt dissolves inwater, what is present is no (...) longer `salt' butrather a collection of hydrated sodium cationsand chloride anions, neither of which isprecisely salt, nor is the collection. Theaqueous material in brine is also significantlydifferent from pure water. Salt may beconsidered to be present in seawater, but onlyin a more or less vague `potential' way.Actually, there is no salt in the sea. In bothancient and modern treatments of otherimportant chemical concepts, including thenotions of `element', related complication,especially polysemy (terms with multiplemeanings), also occurs.In a recent paper, Paul Needham discussed the(predicable) properties of chemical substances,phases, and solutions. He provided a valuablecharacterization of cases in which severalquantities occupy the same space. He alsoconcluded that solution properties are not`intensive', because solvent and solute do nothave parts in common. He tacitly assumed thatingredients are not altered by their inclusionin a solution. This may be the case in somespecial cases (deutero-benzene dissolved inbenzene, say) but is not true in general – andcertainly does not apply to the case of brine,which Needham used as an example – since theions that exist in the solution, and also theaqueous material there, are quite differentfrom the pure ingredients used in making thesolution. An adequate theory of wholes andparts (mereology) must take into account thatwhen individuals enter combinations ofinteresting sorts they no longer are the verysame individuals that existed prior to thecomposition. It appears that no such formaltheory now actually exists. (shrink)

In 1931 eminent chemist Fritz Paneth maintained that the modern notion of “element” is closely related to (and as “metaphysical” as) the concept of element used by the ancients (e.g., Aristotle). On that basis, the element chlorine (properly so-called) is not the elementary substance dichlorine, but rather chlorine as it is in carbon tetrachloride. The fact that pure chemicals are called “substances” in English (and closely related words are so used in other European languages) derives from philosophical compromises made by (...) grammarians in the late Roman Empire (particularly Priscian [fl. ~520 CE]). When the main features of the constitution of isotopes became clear in the first half of the twentieth century, the formal (IUPAC) definition of a “chemical element” was changed. The features that are “essential” to being an element had previously been “transcendental” (“beyond the sphere of consciousness”) but, by the mid-twentieth century the defining characteristics of elements, as such, had come to be understood in detail. This amounts to a shift in a “horizon of invisibility” brought about by progress in chemistry and related sciences. Similarly, chemical insight is relevant to currently-open philosophical problems, such as the status of “the bundle theory” of the coherence of properties in concrete individuals. (shrink)

One of the main functions that introductory chemistry courses have fulfilled during the past century has been to provide evidence for the general validity of 'the atomic hypothesis.' A second function has been to demonstrate that an analytical approach has wide applicability in rationalizing many kinds of phenomena. Following R.G. Collingwood, these two functions can be recognized as related to a philosophical 'cosmology' (worldview, weltanshauung) that became dominant in the later Renaissance. Recent developments in many areas of science, and in (...) chemistry, have emphasized the central importance of understanding synthetic, developmental, and evolutionary aspects of nature. This paper argues that these scientific developments, and changes in other aspects of culture, amount to a widespread shift to an alternative cosmology, a quite different general worldview. To the extent that this is the case, introductory chemistry courses ought to be changed in fundamental ways. Rather that having a main focus on analysis to microscopic components, introductory chemistry instruction should emphasize current scientific understanding of the (synthetic) evolutionary origins of the present world. This altered approach would provide good preparation for future professional work, while also making better contact with the perceived concerns of students. (shrink)

Intra-molecular connectivity (that is, chemical structure) does not emerge from computations based on fundamental quantum-mechanical principles. In order to compute molecular electronic energies (of C 3 H 4 hydrocarbons, for instance) quantum chemists must insert intra-molecular connectivity “by hand.” Some take this as an indication that chemistry cannot be reduced to physics: others consider it as evidence that quantum chemistry needs new logical foundations. Such discussions are generally synchronic rather than diachronic —that is, they neglect ‘historical’ aspects. However, systems of (...) interest to chemists generally are metastable . In many cases chemical systems of a given elemental composition may exist in any one of several different metastable states depending on the history of the system. Molecular structure generally depends on contingent historical circumstances of synthesis and separation, rather than solely or mainly on relative energies of alternative stable states, those energies in turn determined by relationships among components. Chemical structure is usually ‘kinetically-determined’ rather than ‘thermodynamically-determined.’ For instance, cyclical hydrocarbon ring-systems (as in cyclopropene) are produced only in special circumstances. Adequate theoretical treatments must take account of the persistent effects of such contingent historical events whenever they are relevant—as they generally are in chemistry. (shrink)

This volume addresses relations between macroscopic and microscopic description; essential roles of visualization and representation in chemical understanding; historical questions involving chemical concepts; the impacts of chemical ideas on wider cultural concerns; and relationships between contemporary chemistry and other sciences. The authors demonstrate, assert, or tacitly assume that chemical explanation is functionally autonomous. This volume should he of interest not only to professional chemists and philosophers, but also to workers in medicine, psychology, and other fields in which relationships between explanations (...) based on diverse levels of description and investigation are important.

Combinations of molecules, of biological individuals, or of chemical processes can produce effects that are not simply attributable to the constituents. Such non-redundant causality warrants recognition of those coherences as ontologically significant whenever that efficacy is relevant. With respect to such interaction, the effective coherence is more real than are the components. This ontological view is a variety of structural realism and is also a kind of process philosophy. The designation ‘process structural realism’ (PSR) seems appropriate.

Nature abounds in compound individuals. Discrete, functioning entities are made up of components which are, in some sense, also individuals. Scientists sometimes need to be concerned with whether aggregates (e.g.. species of plants) or components (e.g., quarks) exist. but such questions are not generally regarded as having great importance for science. It has often happened, however, that scientific developments have had major significance for subsequent philosophical discussion of problems of the one and the many. Recently, there has been considerable increase (...) in scientific understanding of spontaneous development of spatial and temporal organization (structure) in physical. chemical, and biological systems. In an earlier note (PS 11:35), I suggested that this progress in science raises points that may be helpful in dealing with a question of current importance for process philosophy. This paper provides support for that suggestion. The first section introduces the philosophical problem. The middle sections provide brief non-technical introduction to scientific concepts. The final section combines both topics. (shrink)

In the characterization of the ArCl2 'van der Waals complex', a recognizable pattern of well-defined peaks is observed in the microwave absorption spectrum. In the control of chaos in a chemical oscillatory reaction the power spectrum progressively becomes simpler, at length yielding a single peak. Since both of these cases generate coherences that are centers of agency, they should be considered to produce new chemical entities. Applicability of this ontological approach to coherences of wider societal interest is suggested.

When a group of processes achieves such closure that a set of states of affairs recurs continually, then the effect of that coherence on the world differs from what would occur in the absence of that closure. Such altered effectiveness is an attribute of the system as a whole, and would have consequences. This indicates that the network of processes, as a unit, has ontological significance. Whenever a network of processes generates continual return to a limited set of states of (...) affairs, the system may function as a “whole”— with respect to appropriate interaction partners. The balance achieved by the processes provides the form of definiteness of a unified agent. The causal powers of such coherent aggregates are indeed just the powers of the “constituents acting in concert”. However, the components act in concert in the specific way they do only because of their inclusion in the closed set of interactions that defines the coherence. This renders the causal powers of the coherence defined by that closure non-redundant, and hence the coherence, as a unit, is ontologically significant. The form of definiteness that provides internal coherence also grounds external efficacy of the societal aggregation. The closure is a structural feature of the coherence — possibly, but not necessarily, apparent in spatial structuring. This approach can provide a unified account that includes quantum microphysics, systems biology, and the philosophy of organism ─ without reducing any of these to another. (shrink)

Philosophers have long debated ‘substrate’ and ‘bundle’ theories as to how properties hold together in objects ― but have neglected to consider that every chemical entity is defined by closure of relationships among components ― here designated ‘Closure Louis de Broglie.’ That type of closure underlies the coherence of spectroscopic and chemical properties of chemical substances, and is importantly implicated in the stability and definition of entities of many other types, including those usually involved in philosophic discourse ― such as (...) roses, statues, and tennis balls. Characteristics of composites are often presumed to ‘supervene on’ properties of components. This assumption does not apply when cooperative interactions among components are significant. Once correlations dominate, then adequate descriptions must involve different entities and relationships than those that are involved in ‘fundamental-level’ description of similar but uncorrelated systems. That is to say, descriptions must involve different semantics than would be appropriate if cooperative interactions were insignificant. This is termed ‘Closure Henri Poincaré. Networks of chemical reactions that have certain types of closure of processes display properties that make other more-complex coherences possible. This is termed ‘Closure Jacques Cauvin.’ Each of these three modes of closure provides a sufficient basis for warranted recognition of causal interaction, thus each of them has epistemological significance. Other modes of epistemologically-important closure probably exist. It is important to recognize that causal efficacy generally depends on closure of relationships of constituents. (shrink)

This article aims to clarify how aspects of current chemical understanding relate to some important contemporary problems of philosophy. The first section points out that the long-running philosophical debates concerning how properties stay together in substances have neglected the important topic of structure-determining closure. The second part describes several chemically-important types of closure and the third part shows how such closures ground the properties of chemical substances. The fourth section introduces current discussions of structural realism (SR) and contextual emergence: the (...) final sections reconsider the coherence of the properties of substances and concludes that recognition that structures qualify as determinants of specific outcomes—as ‘causes’ as that designation is used in Standard English—clarifies how properties stay together in chemical entities, and by analogy, how characteristics cohere in ordinary items.

This paper recommends that chemistry educators shift to a different ‘idea of nature’, an alternative ‘worldview.’ Much of contemporary science and technology deals in one way or another with dynamic coherences that display novel and important properties. The notion of how the world works that such studies and practices generate (and require) is quite different from the earlier concepts that are now integrated into science education. Eventual success in meeting contemporary technological and social challenges requires general diffusion of an overall (...) outlook that focuses on creative generation of novel and useful coherences, replacing a worldview that concentrates on analysis of pre-existing items to minimum constituents. Such a shift in emphasis would amount to general adoption of a new basic model of how nature functions. Chemistry educators can and should provide leadership for this urgently-needed development.

During a long and distinguished career, Belgian physical chemist Ilya Prigogine (1917–2003) pursued a coherent research program in thermodynamics, statistical mechanics, and related scientific areas. The main goal of this effort was establishing the origin of thermodynamic irreversibility (the ‘‘arrow of time’’) as local (residing in the details of the interaction of interest), rather than as global (being solely a consequence of properties of the initial singularity – the ‘‘Big Bang’’). In many publications for general audiences, he stated the opinion (...) that this scientific research had great philosophical importance. Prigogine and his colleagues considered that the most recent stages of this research program have been successful, so that the local origins of the arrow of time are now established. There is no scientific consensus as to whether or not this claim is valid. Similarly, there is no consensus on whether the competing global (initial singularity) explanation has been proven.

Origin of a dissipative structure in a chemical dynamic system: occurs under the following constraints: 1) Affinity must be high. (The system must be far from equilibrium.); 2) There must be an auto-catalytic process; 3) A process that reduces the concentration of the auto-catalyst must operate; 4) The relevant parameters (rate constants, etc.) must lie in a range corresponding to a limit cycle trajectory. That is, there must be closure of the network of reaction such that a state sufficiently close (...) to the prior condition is achieved at the corresponding part of each oscillation. If these constraints continue to be met interactions of the system with the rest of the world are quite different in the presence of the dissipative structure than they would be in the absence of that self-organized coherence. Closure of a network of relationships which gives rise to a dissipative structure is a 'unit-determining' feature. The effects of the structure as a whole are the resultants of the effects of the components, but the concentrations of the components at any instant are effects of the closure of the limit cycle. This is an influence on components arising from what those components constitute --- downward causation. (shrink)

Among the many recent volumes dealing with tension between "creation" and "evolution," this one is highly unusual. It does not presuppose that these two ideas are intrinsically at odds. Rather, the general thrust of the work is to explore the possibility that "the two doctrines are not incompatible, that they may indeed be taken to complement one another in important ways.".

This book aims to "develop the idea that evolution is an axiomatic consequence of organismic information and cohesion systems obeying the second law of thermodynamics in a manner analogous to, but not identical with, the second law's usual application in physical and chemical systems." The authors "adhere to a particular methodological approach called phylogenetic systematics." They have "devoted most of their primary research efforts to discovering historical effects in developmental patterns." Finding that "such historical effects seem ubiquitous," they "began to (...) believe that these historical effects were constraints on the evolutionary process, suggesting the influence of a natural law of history.".

At the end of this impressive work, Michael Lockwood observes: "Philosophers, especially British philosophers tend, in my experience, to combine a rather complacent ignorance of science with an excessive respect for it". The author himself seems to be a definite exception to this generalization, since he reports that he has spent more than twenty years "thinking about the mind body problem and the interpretation of quantum mechanics" and displays a critical attitude toward statements based on scientific research. This book outlines (...) a common interpretive framework that may be able to resolve tensions that have long characterized understandings of human mental functioning and of microphysics. The work is addressed to both philosophers and scientists. (shrink)

Longlisted for the PEN/E.O. Wilson Literary Science Writing Award A leading neuroscientist offers a history of the evolution of the brain from unicellular organisms to the complexity of animals and human beings today Renowned neuroscientist Joseph LeDoux digs into the natural history of life on earth to provide a new perspective on the similarities between us and our ancestors in deep time. This page-turning survey of the whole of terrestrial evolution sheds new light on how nervous systems evolved in (...) animals, how the brain developed, and what it means to be human. In The Deep History of Ourselves, LeDoux argues that the key to understanding human behavior lies in viewing evolution through the prism of the first living organisms. By tracking the chain of the evolutionary timeline he shows how even the earliest single-cell organisms had to solve the same problems we and our cells have to solve each day. Along the way, LeDoux explores our place in nature, how the evolution of nervous systems enhanced the ability of organisms to survive and thrive, and how the emergence of what we humans understand as consciousness made our greatest and most horrendous achievements as a species possible.

Ecology and sustainability are current narratives about the behavior of humans toward themselves and the environment. Ecology is defined as a science, and a philosophy of ecology has become a recognized domain of the philosophy of science. For some, sustainability is an accepted, important moral goal. In 2013, a Special Issue of the journal Sustainability dealt with many of the relevant issues. Unfortunately, the economic, ideological, and psychological barriers to ethical behavior and corresponding social action remain great as well as (...) obvious. In this paper, I propose that a new, non-standard and non-propositional logic of real processes, Logic in Reality grounded in physics applies to the science and philosophy of these narratives and helps to explicate them. Given the ecological role of organizations and institutions, reference is often made to organizational or institutional logics as guides to ecological practice. This paper suggests that these logics are either too abstract or too informal to have an impact in a conflictual world. Recognition of the suggested new, transdisciplinary logical dimension of ecological processes may provide credibility and support to new initiatives in ecology and its philosophy. (shrink)

Do doctors fix patients? Or do they heal them? For all of modern medicine’s many successes, discontent with the quality of patient care has combined with a host of new developments, from aging populations to the resurgence of infectious diseases, which challenge medicine’s overreliance on narrowly mechanistic and technical methods of explanation and intervention, or “fixing’ patients. The need for a better balance, for more humane “healing” rationales and practices that attend to the social and environmental aspects of health and (...) illness and the experiencing person, is more urgent than ever. Yet, in public health and bioethics, the fields best positioned to offer countervailing values and orientations, the dominant approaches largely extend and reinforce the reductionism and individualism of biomedicine. The collected essays in To Fix or To Heal do more than document the persistence of reductionist approaches and the attendant extension of medicalization to more and more aspects of our lives. The contributors also shed valuable light on why reductionism has persisted and why more holistic models, incorporating social and environmental factors, have gained so little traction. The contributors examine the moral appeal of reductionism, the larger rationalist dream of technological mastery, the growing valuation of health, and the enshrining of individual responsibility as the seemingly non-coercive means of intervention and control. This paradigm-challenging volume advances new lines of criticism of our dominant medical regime, even while proposing ways of bringing medical practice, bioethics, and public health more closely into line with their original goals. Precisely because of the centrality of the biomedical approach to our society, the contributors argue, challenging the reductionist model and its ever-widening effects is perhaps the best way to press for a much-needed renewal of our ethical and political discourse.

A new demarcation is proposed between Natural Philosophy and non-Natural Philosophy—philosophy tout court—based on whether or not they follow a non-standard logic of real processes. This non-propositional logic, Logic in Reality, is based on the original work of the Franco-Romanian thinker Stéphane Lupasco. Many Natural Philosophies remain bounded by dependence on binary linguistic concepts of logic. I claim that LIR can naturalize—bring into science—part of such philosophies. Against the potential objection that my approach blurs the distinction between science and philosophy, (...) I reply that there is no problem in differentiating experimental physical science and philosophy; any complete distinction between philosophy, including the philosophy of science and the other sciences is invidious. It was historically unnecessary and is unnecessary today. The convergence of science and philosophy, proposed by Wu Kun based on implications of the philosophy of information, supports this position. LIR provides a rigorous basis for giving equivalent ontological value to diversity and identity, what is contradictory, inconsistent, absent, missing or past, unconscious, incomplete, and fuzzy as to their positive counterparts. The naturalized Natural Philosophy resulting from the application of these principles is a candidate for the ‘new synthesis’ called for by the editors. (shrink)

Many people believe in the power of positive thinking (i.e., how thoughts and attitude can shape their future) yet, despite a plethora of books on this subject, no previous author has credibly explained how mere thoughts are able to tangibly influence future events. To explain the connection, Dr. Donlan presents a new paradigm of nature coupled with a viable explanation of how our right cerebral hemisphere has evolved circuitry that can tap into the hidden domain of the metaphysical. To support (...) this premise, he exposes the reader to the worlds of physics, metaphysics, brain architecture, and evolution. Donlan then introduces the many problems associated with the current model and contrasts it with a new view which remedies many of the issues facing theoretical physicists today. Important to its central theme, the book's proposed paradigm supports the remarkable notion that the future can only be created with thoughts. In the final analysis, the author brings his readers through the necessary steps to put this knowledge to work to help them (pre)ordain their own realities. (shrink)

'Fear' is used scientifically in two ways, which causes confusion: it refers to conscious feelings and to behavioral and physiological responses.

Fact checking has become a prominent facet of political news coverage, but it employs a variety of objectionable methodological practices, such as treating a statement containing multiple facts as if it were a single fact and categorizing as accurate or inaccurate predictions of events yet to occur. These practices share the tacit presupposition that there cannot be genuine political debate about facts, because facts are unambiguous and not subject to interpretation. Therefore, when the black-and-white facts—as they appear to the fact (...) checkers—conflict with the claims produced by politicians, the fact checkers are able to see only (to one degree or another) “lies.” The examples of dubious fact-checking practices that we discuss show the untenability of the naïve political epistemology at work in the fact-checking branch of journalism. They may also call into question the same epistemology in journalism at large, and in politics. (shrink)

ABSTRACT The main cause of the crisis was the behavior of the banks—largely a result of misguided incentives unrestrained by good regulation. Conservative ideology, along with unrealistic economic models of perfect information, perfect competition, and perfect markets, fostered lax regulation, and campaign contributions helped the political process along. The banks misjudged risk, wildly overleveraged, and paid their executives handsomely for being short‐sighted; lax regulation let them get away with it—putting at risk the entire economy. The mortgage brokers neglected due diligence, (...) since they would not bear the risk of default once their mortgages had been securitized and sold to others. Others can be blamed: the ratings agencies that judged subprime securities as investment grade; the Fed, which contributed low interest rates; the Bush administration, whose Iraq war and tax cuts for the rich made low interest rates necessary. But low interest rates can be a boon; it was the financial institutions that turned them into a bust. (shrink)
