It is argued that while quantum mechanics contains nonlocal or entangled states, the instantaneous or nonlocal influences sometimes thought to be present due to violations of Bell inequalities in fact arise from mistaken attempts to apply classical concepts and introduce probabilities in a manner inconsistent with the Hilbert space structure of standard quantum mechanics. Instead, Einstein locality is a valid quantum principle: objective properties of individual quantum systems do not change when something is done to another noninteracting system. There is (...) no reason to suspect any conflict between quantum theory and special relativity. (shrink)

It is shown how all the major conceptual difficulties of standard (textbook) quantum mechanics, including the two measurement problems and the (supposed) nonlocality that conflicts with special relativity, are resolved in the consistent or decoherent histories interpretation of quantum mechanics by using a modified form of quantum logic to discuss quantum properties (subspaces of the quantum Hilbert space), and treating quantum time development as a stochastic process. The histories approach in turn gives rise to some conceptual difficulties, in particular the (...) correct choice of a framework (probabilistic sample space) or family of histories, and these are discussed. The central issue is that the principle of unicity, the idea that there is a unique single true description of the world, is incompatible with our current understanding of quantum mechanics.

Stapp’s counterfactual argument for quantum nonlocality based upon a Hardy entangled state is shown to be flawed. While he has correctly analyzed a particular framework using the method of consistent histories, there are alternative frameworks which do not support his argument. The framework dependence of quantum counterfactual arguments, with analogs in classical counterfactuals, vitiates the claim that nonlocal (superluminal) influences exist in the quantum world. Instead it shows that counterfactual arguments are of limited use for analyzing these questions.

This article describes how an empirically supported theory of human behaviour, perceptual control theory, can be used to advance nursing practice and improve health outcomes for people who are accessing nursing care. Nursing often takes a pragmatic approach to the delivery of care, with an emphasis on doing what appears to work. This focus on pragmatism can sometimes take precedence over any consideration of the underlying theoretical assumptions that inform decisions to take one particular approach over another or the mechanisms (...) through which nursing interventions have their effects. For nursing to develop as a profession, there needs to be an increased focus on the core principles that underpin the delivery of care. In addition to understanding what works, nurses must develop their understanding of how and why particular approaches work or do not work. Understanding the fundamental principles that underpin nurses’ actions will lead to more efficient and effective approaches to the delivery of nursing care. It will also enable nurses to maximize those elements of their practice that are most beneficial for people and minimize other activities that either have little effect or actually lead to worse outcomes. In this article, we will propose that the phenomenon of control is fundamental to human health. Perceptual control theory provides a coherent theoretical framework that enables us to understand the phenomenon of control through a functional model of human behaviour. People are healthy when their neurochemical, physiological, biological, psychological and social states are all controlled satisfactorily. We will explain the implications of understanding health as control throughout the paper. From this perspective, we will argue that the aim of nurses and nursing should be to support people to maintain or recover control over those aspects of their lives that are important and meaningful to them.

In this essay I will discuss and appraise two conflicting answers to the question of whether there was a crisis in Ptolemaic astronomy prior to the Copernican revolution. I will begin by giving a brief account of why anybody should be interested in this question. I will discuss the two conflicting answers of Kuhn (1962, 1970), who claims to present evidence which shows that Ptolemaic astronomy was anomaly-ridden at the time of Copernicus, and of Gingerich (1975), who claims that the (...) supposed anomalies, which have been passed down in the historical literature due to poor scholarship, are fictitious. Finally I will appraise Gingerich’s criticism of Kuhn, giving my own evaluation of Gingerich’s arguments. I conclude that Gingerich’s arguments against the existence of a technical crisis in Ptolemaic astronomy prior to Copernicus appear to be, either arguments against the efficacy of the Copernican system, or arguments based on definitions of complexity which are not directly attributable to Kuhn.

This article is a response to various assertions made by B. d'Espagnat about the consistent history approach to quantum mechanics. It is argued that the consistent history interpretation allows for counterfactual definitions, does not imply that the future influences the past, is “realistic” according to d'Espagnat's own definition of that term, and provides a consistent substitute for classical logic in the quantum domain.

Any attempt to introduce probabilities into quantum mechanics faces difficulties due to the mathematical structure of Hilbert space, as reflected in Birkhoff and von Neumann's proposal for a quantum logic. The (consistent or decoherent) histories solution is provided by its single framework rule, an approach that includes conventional (Copenhagen) quantum theory as a special case. Mermin's Ithaca interpretation addresses the same problem by defining probabilities which make no reference to a sample space or event algebra (“correlations without correlata”). But this (...) leads to severe conceptual difficulties, which almost inevitably couple quantum theory to unresolved problems of human consciousness. Using histories allows a sharper quantum description than is possible with a density matrix, suggesting that the latter provides an ensemble rather than an irreducible single-system description as claimed by Mermin. The histories approach satisfies the first five of Mermin's desiderata for a good interpretation of quantum mechanics, including Einstein locality, but the Ithaca interpretation seems to have difficulty with the first (independence of observers) and the third (describing individual systems).

The etiological approach to ‘proper functions’ in biology can be strengthened by relating it to Robert Cummins' general treatment of function ascription. The proper functions of a biological trait are the functions it is assigned in a Cummins-style functional explanation of the fitness of ancestors. These functions figure in selective explanations of the trait. It is also argued that some recent etiological theories include inaccurate accounts of selective explanation in biology. Finally, a generalization of the notion of selective explanation (...) allows an analysis of the proper functions of human artifacts. (shrink)

Robert Solomon’s philosophy of emotion should be understood in the light of his lifelong commitment to existentialism and his advocacy of “the passionate life” as a means of creating value. Although he developed his views in the framework of the “cognitive theory” of emotions, closer examination reveals many themes in common with a socially situated, transactionalist view of emotions.

Abstract: Philosophers interested in Kant's relevance to contemporary debates over the nature of mental content—notably Robert Hanna and Lucy Allais—have argued that Kant ought to be credited with being the original proponent of the existence of ‘nonconceptual content’. However, I think the ‘nonconceptualist’ interpretations that Hanna and Allais give do not show that Kant allowed for nonconceptual content as they construe it. I argue, on the basis of an analysis of certain sections of the A and B editions of (...) the Transcendental Deduction, for a ‘conceptualist’ reading of Kant's Critique of Pure Reason. My contention is that since Kant's notion of empirical intuition makes essential reference to the categories, it must be true for him that no empirical intuition can be given in sensibility independently of the understanding and its categories.

This collection of original essays--by philosophers of biology, biologists, and cognitive scientists--provides a wide range of perspectives on species. Including contributions from David Hull, John Dupre, David Nanney, Kevin de Queiroz, and Kim Sterelny, amongst others, this book has become especially well-known for the three essays it contains on the homeostatic property cluster view of natural kinds, papers by Richard Boyd, Paul Griffiths, and Robert A. Wilson.

In the biological realm, a complete explanation of a trait seems to include an explanation in terms of function. It is natural to ask of some trait, "What is its function?" or "What purpose in the organism does the particular trait serve?" or "What is the goal of its activity?" There are several views concerning the appropriate definition of function for biological matters. Two popular views of function with respect to living things are Cummins' organizational account and the Griffiths/Godfrey-Smith (...) modern history account. Whereas Cummins argues that a trait functions so as to contribute to the general organization of some organism's present structure, Griffiths, and Godfrey-Smith argue that a trait functions because of its fitness with respect to the organism's recent evolutionary history. In this paper, I show how these accounts can be made compatible and compliment one another. Given that structure, organization, operational flexibility, function, and evolutionary history are all factors to be considered in an organism's makeup, we should expect that the traits of an organism function the way they do because such traits presently contribute to the overall organization of the organism (Cummins) as well as were selected for in the organism's species' recent ancestry (Griffiths/Godfrey-Smith).

This paper looks at the themes of nature, humanity, and military and industrial development in the nineteenth century American painter Winslow Homer through the lens of the Hegelian theory of art. Robert Pippin's After the Beautiful has recently put the Hegelian framework to very fruitful use in understanding pictorial modernism. This study of Homer follows a similar approach but argues that Homer's canvases represent a development in the modern spirt which, in many ways, goes beyond the canvases of Manet (...) – a very tight modernist contemporary of Homer's. Homer communicates a presentment of the immense and, in certain profound respects, horrifying power of humanity's growing industrialization. I trace the development of this idea over the course of his career, from this early Civil War canvases to his final seascapes and argue that an understanding of Homer's work is important for understanding the modern spirit of the nineteenth and twentieth centuries.

I have been arguing, for almost thirty years now, that emotions have been unduly neglected in philosophy. Back in the seventies, it was an argument that attracted little sympathy. I have also been arguing that emotions are a ripe for philosophical analysis, a view that, as evidenced by the Manchester 2001 conference and a large number of excellent publications, has now become mainstream. My own analysis of emotion, first published in 1973, challenged the sharp divide between emotions and rationality, insisted (...) that we reject the established notion that the emotions are involuntary, and argued, in a brief slogan, that ‘ emotions are judgments.’ Since then, although the specific term ‘judgment’ has come under considerable fire and my voluntarist thesis continues to attract incredulousness the general approach I took to emotions has been widely accepted in both philosophy and the social sciences. When Paul Griffiths took on what he misleadingly characterized as ‘propositional attitude’ theories of emotion as the enemy of all that was true and scientifically worthy, I knew that we had made it. Such ferocious abuse is surely a sign that we had shifted, in Kuhnian terms, from being revolutionary to becoming the ‘normal’ paradigm. The current counter-revolution of affect programmes and neuro-reductionism says a lot about who we are and how far we have come. (shrink)

In this dissertation, I argue that we ought to accept an agent-causal view of free and responsible action. First, I set the stage for this claim by highlighting our intuitions regarding moral responsibility and freedom, and by ruling out competing positions. I support Harry Frankfurt's claim that responsibility does not require the ability to do otherwise. I go beyond this claim, however, to argue that responsibility requires that one be the true originator of one's action, and that this requires a (...) kind of freedom that is incompatible with determinism. To bolster this last claim, I argue against the compatibilist, “guidance control” view of John Martin Fischer and Mark Ravizza. I believe the weaknesses of their interesting and compelling view denote potential problems for any compatibilist position. After arguing for incompatibilism, I argue against non-agent-causal incompatibilist views. Specifically, I argue against Robert Kane's “teleological intelligibility theory.” In the final chapters of my project, I lay out my agent-causal view. I argue that agent-causation is possible and coherent if one accepts a realist view of causes. I appeal to Randolph Clarke's idea that the relation between agent and cause is the same relation as that between event and cause. This serves to alleviate the “mysteriousness” of agent-causation. Having shown that it is possible and coherent, and having ruled out competing views in preceding chapters, I am now in position to claim that agent-causation is the correct view. I also demonstrate that it is a compelling position in its own right because it accords with our most basic understanding of ourselves as agents. (shrink)

It is widely thought that what finally characterizes American literary narratives is a preoccupation with Americanness. If the "great theme" of European fiction has been "man's life in society," Walter Allen writes in The Modern Novel, "the great theme of American fiction has been the exploration of what it means to be an American." The best American film narratives also seem to bear out this proposition, especially those of the great American naturals like Griffith and Ford and Hawks, and most (...) especially Orson Welles' Citizen Kane , regarded by many as the greatest American film. Welles' film belongs to that category of narratives which take a prominent figure from contemporary American life and use him to stand for what are conceived to be representative traits of the collective American character. Understandably, then, there are many general resemblances in the film to other well-known stories of American entrepreneurs, magnates, and tycoons. Long before the flourishing of tycoon biographies in the American sound film, well before F. Scott Fitzgerald or Sinclair Lewis or Theodore Dreiser, before even Henry James, certain conventions and associations had become well established in stories of this type. The up-and-coming young American was shrewd and practical, an image of compulsive energy, a man with his eye always on the future. His Americanness also consisted of such traits as enterprise, indomitable idealism, a certain naturalness and openness to experience, and a relentless will to succeed. His geographical origin could be made to carry moral force, and he or another character who equated American commercial noblesse oblige with universal morality could be a useful thematic touchstone. Robert L. Carringer is an assistant professor of English at the University of Illinois at Urbana-Champaign. He teaches and writes on film, American literature, and interdisciplinary approaches to literature. This study is the first in a series of essays in progress on American films and American narrative tradition. He has also contributed "The Scripts of Citizen Kane" to Critical Inquiry. (shrink)

The species problem is one of the oldest controversies in natural history. Its persistence suggests that it is something more than a problem of fact or definition. Considerable light is shed on the species problem when it is viewed as a problem in the representation of the natural system (sensu Griffiths, 1974, Acta Biotheor. 23: 85–131; de Queiroz, 1998, Philos. Sci. 55: 238–259). Just as maps are representations of the earth, and are subject to what is called cartographic generalization, (...) so diagrams of the natural system (evolutionary trees) are representations of the evolutionary chronicle, and are subject to a temporal version of cartographic generalization which may be termed systematic generalization. Cartographic generalization is based on judgements of geographical importance, and systematic generalization is based on judgements of historical importance, judgements expressed in narrative sentences (sensu Danto, 1985, Narration and knowledge, Columbia Univ. Press, New York). At higher systematic levels these narrative sentences are conventional and retrospective, but near the "species" level they become prospective, that is, dependent upon expectations of the future. The truth of prospective narrative sentences is logically indeterminable in the present, and since all the common species concepts depend upon prospective narration, it is impossible for any of them to be applied with precision.

In a recent article, Meghan Griffith (American Philosophical Quarterly 47:43–56, 2010) argues that agent-causal libertarian theories are immune to the problem of luck but that event-causal theories succumb to this problem. In making her case against the event-causal theories, she focuses on Robert Kane’s event-causal theory. I provide a brief account of the central elements of Kane’s theory and I explain Griffith’s critique of it. I argue that Griffith’s criticisms fail. In doing so, I note some important respects in (...) which Kane’s view is unclear and I suggest a plausible way of reading Kane that makes his theory immune to Griffith’s objections. (shrink)

Background Researchers are required to determine whether a person has capacity to consent to a research study before they are able to participate. The Mental Capacity Act and accompanying Code of Practice for England and Wales provide some guidance on this process, but researchers have identified that it can be difficult to determine capacity to consent when a person has complex cognitive or communication needs. This study aimed to understand the experiences and opinions of researchers who recruit people with dementia (...) to research projects, to inform the future development of training resources. Methods A mixed method, cross-sectional, electronic survey was circulated via social media and research networks in England and Wales. The survey remained open for ten weeks and included open and closed questions exploring respondents’ confidence in determining capacity in the context of recruiting people with dementia to consent, their views on training and support they have experienced and their suggestions for future training and support needs. Results 60 respondents completed the survey from across England and Wales. Although 75% of respondents had experience of determining capacity to consent with people with dementia to research, only 13% rated themselves as feeling ‘very confident’ in this. Qualitative content analysis of open responses led to the generation of six themes, explaining researchers’ confidence, competence and future training needs in this area: (1) Researcher uncertainties, (2) Lack of time, (3) Balancing information complexity with accessibility, (4) Gatekeepers, (5) Existing enablers and (6) Envisioning future training. Conclusions Researchers would benefit from specific training in undertaking conversations around consent with people with dementia. People with dementia may have fluctuating capacity, and despite support from caregivers, researchers have little practical guidance on methods of determining a person’s ability to understand or appreciate the information they have provided during the consent process. Given the development of large complex trials within dementia research, there is an urgency to develop specific and practical guidance and training for researchers working with people with dementia and their families.

Developmental systems theory (DST) is a general theoretical perspective on development, heredity and evolution. It is intended to facilitate the study of interactions between the many factors that influence development without reviving `dichotomous' debates over nature or nurture, gene or environment, biology or culture. Several recent papers have addressed the relationship between DST and the thriving new discipline of evolutionary developmental biology (EDB). The contributions to this literature by evolutionary developmental biologists contain three important misunderstandings of DST.

Robert MacArthur's mathematical ecology is often regarded as ahistorical and has been criticized by historically oriented ecologists and philosophers for ignoring the importance of history. I clarify and defend his approach, especially his use of simple mathematical models to explain patterns in data and to generate predictions that stimulate empirical research. First I argue that it is misleading to call his approach ahistorical because it is not against historical explanation. Next I distinguish three kinds of criticism of his approach (...) and argue that his approach is compatible with the first two of them. Finally, I argue that the third kind of criticism, advanced by Kim Sterelny and Paul Griffiths, is largely irrelevant to MacArthur's approach. ‡I am especially grateful to Thomas Nickles for encouragement and helpful comments on earlier versions of this paper.
