Although skeptical of the prohibitive power of no-hidden-variables theorems, John Bell was himself responsible for the two most important ones. I describe some recent versions of the lesser known of the two (familiar to experts as the "Kochen-Specker theorem") which have transparently simple proofs. One of the new versions can be converted without additional analysis into a powerful form of the very much better known "Bell's Theorem," thereby clarifying the conceptual link between these two results of Bell.

We review the famous no-hidden-variables theorem in von Neumann’s 1932 book on the mathematical foundations of quantum mechanics. We describe the notorious gap in von Neumann’s argument, pointed out by Hermann and, more famously, by Bell. We disagree with recent papers claiming that Hermann and Bell failed to understand what von Neumann was actually doing.

In a recent article under the above title (but without the question mark) Henry Stapp has presented arguments which lead him to conclude that under suitable conditions “the truth of a statement that refers only to phenomena confined to an earlier time” must “depend on which measurement an experimenter freely chooses to perform at a later time.” I suggest that this conclusion contains an essential ambiguity as regards the meaning of the expression “statement referring only to phenomena confined to an (...) earlier time,” when such a statement talks about the outcome of an experiment that was not actually performed. As a result Stapp’s argumentation does not imply that future choices can affect present facts. But it does provide a wonderful and instructively different opportunity to reexamine a central point of Bohr’s famous reply to Einstein, Podolsky, and Rosen. (shrink)

This book presents an elementary but complete exposition of the relativistic theory of the measurement of intervals in space & time.

In honor of Daniel Greenberger's 65th birthday, I record for posterity two superb examples of his wit, offer a proof of an important theorem on quantum correlations that even those of us over 60 can understand, and suggest, by trying to make it look silly, that invoking “quantum nonlocality” as an explanation for such correlations may be too cheap a way out of the dilemma they pose.

I describe a pedagogical scheme devised to teach efficiently to computer scientists just enough quantum mechanics to permit them to understand the theoretical developments of the last decade going under the name of “quantum computation.” I then note that my offbeat approach to quantum mechanics, designed to be maximally efficacious for this specific educational purpose, is nothing other than the Copenhagen interpretation.

One of the endearing traits of Asher Peres is that when somebody publishes something he knows to be wrong, he does not bother to refute it, even if the paper criticizes his own work. Life is too brief for such frivolity. As a small 70th birthday present I would like to answer one such recent attack. It’s not much of a present, since Asher will not read my paper. Why should he? He already knows this criticism is nonsense. But somebody (...) has to set the written record straight for future historians, so I will do it as part of this celebration. Fortunately this particular issue is so easily settled that this can be a very short paper. Since Asher is a master of the very short paper, my Peresian brevity is an important part of my act of homage. The criticism I address can be found in a new formulation by Karl Hess and Walter Philipp(1) of their view that all versions of Bell’s theorem are fundamentally flawed. I focus here only on their criticism of the version in Asher’s book.(2). (shrink)

There have been serious controversies in the latter part of the 20th century about the roles and functions of scientific and medical research. In whose interests are medical and biomedical experiments conducted and what are the ethical implications of experimentation on subjects unable to give competent consent? From the decades following the Second World War and calls for the global banning of medical research to the cautious return to the notion that in controlled circumstances, medical research on human subjects is (...) in the best interest of the given individual and the broader population, this book addresses the key implications of experimentation on humans. This volume covers major ethical themes within biomedical research providing historical, philosophical, legal and policy reflections on the literature and specific issues in the field of research on human subjects. Focusing on special populations (the elderly, children, prisoners and the cognitively impaired) it represents the most up-to-date review of the special ethical and legal conflicts that arise with relation to experimentation on subjects from these groups. In the light of current initiatives for law reform pertaining to research ethics the world over, this volume provides a timely, comprehensive and provocative exploration of the field. The volume has been carefully organized to present important philosophical perspectives on organizing principles that should underlie any practical application. A forward-looking historical review of the regulatory regimes of principal jurisdictions, including of the legal controls already in place, provides the backdrop for future policy initiatives. Additionally, in the light of global restructuring of health care systems, several chapters have been devoted to epidemiological research and related issues. (shrink)

This is an introductory guide to the basic principles of constructing good arguments and criticizing bad ones. It is nontechnical in its approach, and is based on 150 key examples, each discussed and evaluated in clear, illustrative detail. The author explains how errors, fallacies, and other key failures of argument occur. He shows how correct uses of argument are based on sound argument strategies for reasoned persuasion and critical questions for responding. Among the many subjects covered are: techniques of posing, (...) replying to, and criticizing questions, forms of valid argument, relevance, appeals to emotion, personal attack, uses and abuses of expert opinion, problems in deploying statistics, loaded terms, equivocation, and arguments from analogy.

Philosophers and psychologists are increasingly investigating the conditions under which multiple explanations are better in conjunction than they are individually. This book brings together leading scholars to provide an interdisciplinary and unified discussion of such "conjunctive explanations." The book starts with an introductory chapter expounding the notion of conjunctive explanation and motivating a multifaceted approach to its study. The remaining chapters are divided into three parts. Part I includes chapters on "The Nature of Conjunctive Explanations." Each chapter illustrates distinct ways (...) in which explanatory multiplicity is motivated by a careful study of the nature and concept of explanation. The second part ("Reasoning about Conjunctive Explanations") includes chapters on the epistemology and logic of conjunctive explanations. Here the contributors propose and evaluate various norms for reasoning correctly about and to conjunctive explanations. Part III concerns "The Psychology of Conjunctive Explanations," with contributions discussing conditions under which humans entertain and hold multiple explanations of single explananda simultaneously and the cognitive limitations and capacities for doing so. Conjunctive Explanations will be of interest to researchers and advanced students working on explanation in philosophy of science, epistemology, philosophical logic, and cognitive psychology.

Machine learning algorithms may radically improve our ability to diagnose and treat disease. For moral, legal, and scientific reasons, it is essential that doctors and patients be able to understand and explain the predictions of these models. Scalable, customisable, and ethical solutions can be achieved by working together with relevant stakeholders, including patients, data scientists, and policy makers.

The paper considers contemporary models of presumption in terms of their ability to contribute to a working theory of presumption for argumentation. Beginning with the Whatelian model, we consider its contemporary developments and alternatives, as proposed by Sidgwick, Kauffeld, Cronkhite, Rescher, Walton, Freeman, Ullmann-Margalit, and Hansen. Based on these accounts, we present a picture of presumptions characterized by their nature, function, foundation and force. On our account, presumption is a modal status that is attached to a claim and has the (...) effect of shifting, in a dialogue, a burden of proof set at a local level. Presumptions can be analysed and evaluated inferentially as components of rule-based structures. Presumptions are defeasible, and the force of a presumption is a function of its normative foundation. This picture seeks to provide a framework to guide the development of specific theories of presumption. (shrink)

Stamos squarely confronts the problem of determining what a biological species is, whether species are real, and the nature of their reality. He critically considers the evolution of the major contemporary views of species and also offers his own solution to the species problem.

This book is designed to appeal both to those interested in Roman poetry and to specialists in ancient philosophy. In it David Sedley explores Lucretius ' complex relationship with Greek culture, in particular with Empedocles, whose poetry was the model for his own, with Epicurus, the source of his philosophical inspiration, and with the Greek language itself. He includes a detailed reconstruction of Epicurus' great treatise On Nature, and seeks to show how Lucretius worked with this as his sole (...) philosophical source, but gradually emancipated himself from its structure, transforming its raw contents into something radically new. By pursuing these themes, the book uncovers many unrecognised aspects of Lucretius ' methods and achievements as a poetic craftsman. (shrink)

Ethnobiology has become increasingly concerned with applied and normative issues such as climate change adaptation, forest management, and sustainable agriculture. Applied ethnobiology emphasizes the practical importance of local and traditional knowledge in tackling these issues but thereby also raises complex theoretical questions about the integration of heterogeneous knowledge systems. The aim of this article is to develop a framework for addressing questions of integration through four core domains of philosophy - epistemology, ontology, value theory, and political theory. In each of (...) these dimensions, we argue for a model of “partial overlaps” that acknowledges both substantial similarities and differences between knowledge systems. While overlaps can ground successful collaboration, their partiality requires reflectivity about the limitations of collaboration and co-creation. By outlining such a general and programmatic framework, the article aims to contribute to developing “philosophy of ethnobiology” as a field of interdisciplinary exchange that provides new resources for addressing foundational issues in ethnobiology and also expands the agenda of philosophy of biology.

Business ethics can be regarded as a field dealing with corporate _self-regulation_ as it relates to the treatment of stakeholders. However, a concern for corporate stakeholders need not take a corporate-centric perspective, as shown by recent efforts (especially Singer in Bus Ethics Q 25(1):65–92, 2015) to situate corporate conduct within Rawls’ political theory. Although Rawls was largely mute on the subject himself, his theory has implications for business ethics and corporate governance more specifically. Given an understanding of a “Rawlsian society” (...) as a whole—where corporations as associations are a part—this paper addresses how a Rawlsian perspective would safeguard against corporate harms in society. We argue that a Rawlsian society would primarily regulate corporate conduct through exogenous constraints in the form of legislation. To the extent that business ethics is concerned with endogenous constraints in the form of corporate-centric self-regulation regarding _stakeholders_, to adopt a Rawlsian perspective is to assume instead a society-centric perspective and to impose exogenous constraints on corporate conduct in the form of legislation for the benefit of _citizens_. In the context of Rawls’ political liberalism, normative concerns in business are accounted for through legislation and the system of background justice. In a clear departure from Singer (Bus Ethics Q 25(1):65–92, 2015, Bus Ethics J Rev 6(3):11–17, 2018a), we further develop our argument to propose that Rawls' theory can be interpreted as providing a rule for corporate governance. The rule—which is imposed exogenously for the good of society—states: After choosing the corporate constraint mechanism (exogenous vs. endogenous) that best promotes the Liberty Principle, choose the corporate control regime (shareholder vs. stakeholder) that maximizes economic efficiency.

This paper examines the shareholder primacy norm as a widely acknowledged impediment to corporate social responsibility and explores the role of business schools in promoting the SPN but also potentially as an avenue for change by addressing misconceptions about shareholder primacy and the purpose of business. We start by explaining the SPN and then review its status under US and UK laws and show that it is not a likely legal requirement, at least under the guise of shareholder value maximization. (...) This is in contrast to the common assertion that managers are legally constrained from addressing CSR issues if doing so is inconsistent with the economic interests of shareholders. Nonetheless, while the SPN might be muted as a legal norm, we show that it is certainly evident as a social norm among managers and in business schools—reflective, in part, of the sole voting rights of shareholders on corporate boards and of the dominance of shareholder theory—and justifiably so in the view of many managers and business academics. We argue that this view is misguided, not least when associated with claims of a purported legally enforceable requirement to maximize shareholder value. We propose two ways by which the influence of the SPN among managers might be attenuated: extending fiduciary duties of executives to non-shareholder stakeholders and changes in business school teaching such that it covers a plurality of conceptions of the purpose of the corporation.

Extinct megafaunal mammals in the Americas are often linked to seed-dispersal mutualisms with large-fruiting tree species, but large-fruiting species in Europe and Asia have received far less attention. Several species of arboreal Maloideae (apples and pears) and Prunoideae (plums and peaches) evolved large fruits starting around nine million years ago, primarily in Eurasia. As evolutionary adaptations for seed dispersal by animals, the size, high sugar content, and bright colorful visual displays of ripeness suggest that mutualism with megafaunal mammals facilitated the (...) evolutionary change. There has been little discussion as to which animals were likely candidate(s) on the late Miocene landscape of Eurasia. We argue that several possible dispersers could have consumed the large fruits, with endozoochoric dispersal usually relying on guilds of species. During the Pleistocene and Holocene, the dispersal guild likely included ursids, equids, and elephantids. During the late Miocene, large primates were likely also among the members of this guild, and the potential of a long-held mutualism between the ape and apple clades merits further discussion. If primates were a driving factor in the evolution of this large-fruit seed-dispersal system, it would represent an example of seed-dispersal-based mutualism with hominids millions of years prior to crop domestication or the development of cultural practices, such as farming.

In "The Indeterministic Character of Evolutionary Theory: No 'Hidden Variables Proof' But No Room for Determinism Either," Brandon and Carson (1996) argue that evolutionary theory is statistical because the processes it describes are fundamentally statistical. In "Is Indeterminism the Source of the Statistical Character of Evolutionary Theory?" Graves, Horan, and Rosenberg (1999) argue in reply that the processes of evolutionary biology are fundamentally deterministic and that the statistical character of evolutionary theory is explained by epistemological rather than ontological considerations. In (...) this paper I focus on the topic of mutation. By focusing on some of the theory and research on this topic from early to late, I show how quantum indeterminism hooks up to point mutations (via tautomeric shifts, proton tunneling, and aqueous thermal motion). I conclude with a few thoughts on some of the wider implications of this topic. (shrink)

Mary Winsor (2003) argues against the received view that pre-Darwinian taxonomy was characterized mainly by essentialism. She argues, instead, that the methods of pre-Darwinian taxonomists, in spite of whatever their beliefs, were that of clusterists, so that the received view, propagated mainly by certain modern biologists and philosophers of biology, should at last be put to rest as a myth. I argue that shes right when it comes to higher taxa, but wrong when it comes the most important category of (...) all, the species category. (shrink)

In addition to the distinction between species as a category and speciesas a taxon, the word species is ambiguous in a very different butequally important way, namely the temporal distinction between horizontal andvertical species. Although often found in the relevant literature, thisdistinction has thus far remained vague and undefined. In this paper the use ofthe distinction is explored, an attempt is made to clarify and define it, andthen the relation between the two dimensions and the implications of thatrelation are examined. (...) Using Darwin's analogy of language evolution forspeciesevolution, and by appealing to a major change in the conception of languagebetween 19th- and 20th-century linguistics, it is argued that the horizontaldimension has priority (pragmatic, epistemological, logical, and ontological)over the vertical dimension. This has immense ramifications for the modernspecies problem. Fundamentally, it favors horizontal species concepts oververtical ones. In so doing it places species realism on a much more securefoundation and largely undercuts species pluralism. In addition it raises aserious problem for the increasingly popular family of phylogenetic speciesconcepts, which generally suffer from a dimensionality confusion. However,thereis a recent trend within this family that attempts to restore the priority ofthe horizontal dimension. It is concluded that this trend should be affirmedandthat the species-as-individuals view should be abandoned. (shrink)

Crystallography has proven a rich source of ideas over several centuries. Among the many ways of looking at space groups, N. David Mermin has pioneered the Fourier-space approach. Recently, we have supplemented this approach with methods borrowed from algebraic topology. We now show what topology, which studies global properties of manifolds, has to do with crystallography. No mathematics is assumed beyond what the typical physics or crystallography student will have seen of group theory; in particular, the reader need not (...) have any prior exposure to topology or to cohomology of groups.

First, a brief history is provided of Popper's views on the status of evolutionary biology as a science. The views of some prominent biologists are then canvassed on the matter of falsifiability and its relation to evolutionary biology. Following that, I argue that Popper's programme of falsifiability does indeed exclude evolutionary biology from within the circumference of genuine science, that Popper's programme is fundamentally incoherent, and that the correction of this incoherence results in a greatly expanded and much more realistic (...) concept of what is empirical, resulting in the inclusion of evolutionary biology. Finally, this expanded concept of empirical is applied to two particular problems in evolutionary biology — viz., the species problem and the debate over the theory of punctuated equilibria — and it is argued that both of them are still mainly metaphysical.

Gayon's recent claim that Buffon developed a concept of species as physical individuals is critically examined and rejected. Also critically examined and rejected is Gayon's more central thesis that as a consequence of his analysis of Buffon's species concept, and also of Darwin's species concept, it is clear that modern evolutionary theory does not require species to be physical individuals. While I agree with Gayon's conclusion that modern evolutionary theory does not require species to be physical individuals, I disagree with (...) his reasons and instead provide logical rather than historical reasons for the same conclusion.

This article addresses all of the issues involved in the debate about whether or not bioethicists should be paid by private biomedical companies to perform consultations. These issues include the following: differentiation of this role from bioethicists' other roles, an analysis of to whom bioethicists owe a duty, consideration of what bioethicists are “selling,” whether bioethicists should be allowed to get paid, when payment becomes problematic, and whether consulting fee arrangements should be regulated. The author often compares bioethicists' relationship to (...) the companies to bioethicists' other relationships, as well as to professional relationships in other fields, such as law and accounting.
