We provide complete classifications of algebras of partial maps for a significant swathe of combinations of operations not previously classified. Our focus is the many subsidiary operations that arise in recent considerations of the ‘override’ and ‘update’ operations arising in specification languages. These other operations turn out to have an older pedigree: domain restriction, set subtraction and intersection. All signatures considered include domain restriction, at least as a term. Combinations of the operations are classified and given complete axiomatizations with and (...) without the presence of functional composition. Each classification is achieved by way of providing a concrete representation of the corresponding abstract algebras as partial maps acting on special kinds of filters determined with respect to various induced orders. In contrast to many negative results in the broader area, all of the considered combinations lead to finite axiomatizations. (shrink)

Demonic composition, demonic refinement and demonic union are alternatives to the usual ‘angelic’ composition, angelic refinement (inclusion) and angelic (usual) union defined on binary relations. We first motivate both the angelic and the demonic via an analysis of the behaviour of non-deterministic programs, with the angelic associated with partial correctness and demonic with total correctness, both cases emerging from a richer algebraic model of non-deterministic programs incorporating both aspects. Zareckiĭ has shown that the isomorphism class of algebras of binary relations (...) under angelic composition and inclusion is finitely axiomatized as the class of ordered semigroups. The proof can be used to establish that the same axiomatization applies to binary relations under demonic composition and refinement, and a further modification of the proof can be used to incorporate a zero element representing the empty relation in the angelic case and the full relation in the demonic case. For the signature of angelic composition and union, it is known that no finite axiomatization exists, and we show the analogous result for demonic composition and demonic union by showing that the same axiomatization holds for both. We show that the isomorphism class of algebras of binary relations with the ‘mixed’ signature of demonic composition and angelic inclusion has no finite axiomatization. As a contrast, we show that the isomorphism class of partial algebras of binary relations with the partial operation of constellation product and inclusion (also a ‘mixed’ signature) is finitely axiomatizable.

In order to create sustainable health systems, many countries are introducing ways to prioritize health services underpinned by a process of health technology assessment. While this approach requires technical judgments of clinical effectiveness and cost-effectiveness, these are embedded in a wider set of social (societal) value judgments, including fairness, responsiveness to need, non-discrimination and obligations of accountability and transparency. Implementing controversial decisions faces legal, political and public challenge. To help generate acceptance for the need for health prioritization and the resulting (...) decisions, the purpose of this paper is to develop a novel way of encouraging key stakeholders, especially patients and the public, to become involved in the prioritization process.

The passage of Mill’s Utilitarianism that sets out the condition in which one pleasure has a superior quality than another stokes interpretive controversy. According to the Lexical Interpretation, Mill takes one pleasure, P1, to be of a superior quality than another, P2, if, and only if, the smallest quantity of P1 is more valuable than any finite quantity of P2. This paper argues that, while the Lexical Interpretation may be supported with supplementary evidence, the passage itself does not rule (...) out qualitative superiority without lexical dominance, as it only requires P1 to be more valuable than any quantity of P2 that it is possible for someone to experience. Some will object that this concession to opponents of the Lexical Interpretation still renders Mill’s condition for qualitative superiority too demanding to be plausible. However, if Mill’s qualitative rankings apply to higher-order pleasures taken in modes of existence as such rather than to the pleasures of different activities chosen from within these modes, the objection loses much of its force. One upshot is that Mill may have more to contribute to debates in contemporary population axiology than is usually acknowledged. (shrink)

We offer a brief characterization of creativity, followed by a review of some of the reasons people have been skeptical about the possibility of explaining creativity. We then survey some of the recent work on creativity that is naturalistic in the sense that it presumes creativity is natural (as opposed to magical, occult, or supernatural) and is therefore amenable to scientific inquiry. This work is divided into two categories. The broader category is empirical philosophy, which draws on empirical research while (...) addressing questions that have traditionally been regarded as philosophical. The second category is experimental philosophy, a special branch of empirical philosophy in which experiments are designed (by philosophers) with the explicit purpose of addressing philosophical questions. All of this highlights the relative theoretical neglect of creativity, while at the same time suggesting ample opportunity for experimentally minded philosophers to break new ground. (shrink)

Much recent work on the ethics of new biomedical technologies is committed to hidden, contestable views about the nature of biological reality. This selection of essays by Tim Lewens explores and scrutinises these biological foundations, and includes work on human enhancement, synthetic biology, and justice in healthcare decision-making.

Differences in ethical ideology are thought to influence individuals'' reasoning about moral issues (Forsyth and Nye, 1990; Forsyth, 1992). To date, relatively little research has addressed this proposition in terms of business-related ethical issues. In the present study, four groups, representing four distinct ethical ideologies, were created based on the two dimensions of the Ethical Position Questionnaire (idealism and relativism), as posited by Forsyth (1980). The ethical judgments of individuals regarding several business-related issues varied, depending upon their ethical ideology.

This book on the philosophy of science argues for an empiricism, opposed to the tradition of David Hume, in which singular rather than general causal claims are primary; causal laws express facts about singular causes whereas the general causal claims of science are ascriptions of capacities or causal powers, capacities to make things happen. Taking science as measurement, Cartwright argues that capacities are necessary for science and that these can be measured, provided suitable conditions are met. There are case studies (...) from both econometrics and quantum mechanics. (shrink)

The aim of this essay is to distinguish and analyze several difficulties confronting attempts to reconcile the fundamental quantum mechanical dynamics with Born''s rule. It is shown that many of the proposed accounts of measurement fail at least one of the problems. In particular, only collapse theories and hidden variables theories have a chance of succeeding, and, of the latter, the modal interpretations fail. Any real solution demands new physics.

This paper sketches a taxonomy of forms of substantivalism and relationism concerning space and time, and of the traditional arguments for these positions. Several natural sorts of relationism are able to account for Newton's bucket experiment. Conversely, appropriately constructed substantivalism can survive Leibniz's critique, a fact which has been obscured by the conflation of two of Leibniz's arguments. The form of relationism appropriate to the Special Theory of Relativity is also able to evade the problems raised by Field. I survey (...) the effect of the General Theory of Relativity and of plenism on these considerations. (shrink)

This essay is the first act of a two-act play. My ultimate aim is to defend a simple proposition: time passes. To be more precise, I want to defend the claim that the passage of time is an intrinsic asymmetry in the structure of space-time itself, an asymmetry that has no spatial counterpart and is metaphysically independent of the material contents of space-time. It is independent, for example, of the entropy gradient of the universe. This view is part of common-sense, (...) but has been widely attacked by philosophers. The passage of time, we are told, is a myth, an illusion, even an incoherent notion. Because the notion that time passes is common sense, it perhaps requires little positive defence; if there are no weighty objections to the view, it ought to be accepted. So the first, and more important, act of the play is defusing the arguments which have been used to cast doubt on the passage of time. I have positive arguments to give, but not having space for them here, I will confine myself to an examination of the common philosophical arguments that have been used to cast doubt on the passage of time.

The Naked Self explores Søren Kierkegaard's understanding of selfhood by situating his work in relation to central problems in contemporary philosophy of personal identity: the role of memory in selfhood, the relationship between the notional and actual subjects of memory and anticipation, the phenomenology of diachronic self-experience, affective alienation from our past and future, psychological continuity, practical and narrative approaches to identity, and the intelligibility of posthumous survival. By bringing his thought into dialogue with major living and recent philosophers of (...) identity, Stokes reveals Kierkegaard as a philosopher with a significant--if challenging--contribution to make to philosophy of self and identity.

The present study extends the study of individuals' ethical ideology withinthe context of marketing ethics issues. A national sample of marketing professionals participated. Respondents' ethical ideologies were classified as absolutists, situationists, exceptionists, or subjectivists using the Ethical Position Questionnaire (Forsyth, 1980). Respondents then answered questions about three ethically ambiguous situations common to marketing and sales. The results indicated that marketers' ethical judgments about the situations differed based on their ethical ideology, with absolutists rating the actions as most unethical. The findings (...) are consistent with those of two earlier studies that utilized samples of business students (Barnett et al., 1994, 1995). The results suggest that personal moral philosophy is an important influence on ethical decision making that should be considered in empirical studies of business ethics. The results also support the utility of the Ethical Position Questionnaire (Forsyth, 1980) as a means for researchers and practitioners to assess individuals' ethical ideology. (shrink)

Expertise is a cognitive achievement that clearly involves experience and learning, and often requires explicit, time-consuming training specific to the relevant domain. It is also intuitive that this kind of achievement is, in a rich sense, genuinely perceptual. Many experts—be they radiologists, bird watchers, or fingerprint examiners—are better perceivers in the domain(s) of their expertise. The goal of this paper is to motivate three related claims, by substantial appeal to recent empirical research on perceptual expertise: Perceptual expertise is genuinely perceptual (...) and genuinely cognitive, and this phenomenon reveals how we can become epistemically better perceivers. These claims are defended against sceptical opponents that deny significant top-down or cognitive effects on perception, and opponents who maintain that any such effects on perception are epistemically pernicious.

[File is the introduction to the monograph] -/- Abstract to monograph -/- How and whether thinking affects perceiving is a deeply important question. Of course it is of scientific interest: to understand the human mind is to understand how we best distinguish its processes, how those processes interact, and what this implies for how and what we may know about the world. And so in the philosopher’s terms, this book is one on both mental architecture and the epistemology of perception. (...) But there is a more human interest. How we make contact with the world, and with one another, is of the most basic of importance. We can make both sensory contact and cognitive contact with the world. The first is traditionally supposed to be determined by the biological nature of our sensory systems, while the second is at least partly determined by us, what we have learned, our experiences, and so on. The most basic claim of the book is that this is mistaken and importantly so. Our sensory contact with the world can also change and in a way that is importantly affected by the cognitive contact that we have, or have had, with the world. Thinking does not just affect perceiving, thinking improves perceiving. If this is true, it changes not only how we should theorize the mind, it changes how we should understand, as individuals, our place in and contact with the world. (shrink)

Abstract Of the many ways in which identity is constructed and performed online, few are as strongly ‘anchored’ to existing offline relationships as in online social networks like Facebook and Myspace. These networks utilise profiles that extend our practical, psychological and even corporeal identity in ways that give them considerable phenomenal presence in the lives of spatially distant people. This raises interesting questions about the persistence of identity when these online profiles survive the deaths of the users behind them, via (...) the practice of ‘memorialising’ social network profile pages. I situate these practices within a phenomenology of grief that accounts for the ways in which the dead can persist as moral patients, and show how online survival in this case illuminates an important difference between persons and selves within contemporary philosophy of personal identity. Ultimately, the online persistence of the dead helps bring into view a deep ontological contradiction implicit in our dealings with death: the dead both live on as objects of duty and yet completely cease to exist.

Karl Popper is a philosopher of knowledge and politics, rationality and freedom. His ideas have won acceptance and provoked controversy among an academic as well as a more general audience. This book aims to broaden our understanding of Popper's philosophy. It is one of the few studies to present his work as an evolving "system of ideas", and to take account of the full range of his writings. The book discusses Popper's early philosophy of politics, science and social science, as (...) well as his later philosophy, which offers an evolutionary account of human nature and the growth of knowledge. Contrary to many earlier interpretations, Stokes argues that we should look to Popper's political values to understand the unity of his work and the evolution of his theory of knowledge and general philosophy. The chapters in this book examine Popper's arguments, and offer critical analysis of the achievements and shortcomings of his philosophy. In particular, Stokes considers the problems of rationality, politics and ethics in the context of debates between the Frankfurt School of critical theory and critical rationalism. The book will be of interest to second-year undergraduates and above in the fields of philosophy and critical theory. (shrink)

In the September 2020 edition of Perception, Alan Gilchrist published an editorial entitled “The Integrity of Vision” (Gilchrist, 2020). In it, Gilchrist critiques motivated perception research. His main points are as follows: (1) Motivated perception is compromised by experimental demand: Results do not actually show motivated perception but instead reflect subjects’ desires to comply with inferred predictions. (2) Motivated perception studies use designs that make predictions obvious to subjects. These transparent designs conspire with experimental demand to yield confirmatory but compromised (...) results. (3) Motivated perception research lacks guiding theory and cannot explain what appear to be contradictory results. (4) Motivated perception presents an unsupportable assault upon the impermeability of perception. The present commentary responds to these four assertions. (shrink)

Philosophers of mind and cognitive scientists have recently taken renewed interest in cognitive penetration, in particular, in the cognitive penetration of perceptual experience. The question is whether cognitive states like belief influence perceptual experience in some important way. Since the possible phenomenon is an empirical one, the strategy for analysis has, predictably, proceeded as follows: define the phenomenon and then, definition in hand, interpret various psychological data. However, different theorists offer different and apparently inconsistent definitions. And so in addition to (...) the usual problems (e.g., definitions being challenged by counterexample), an important result is that different theorists apply their definitions and accordingly get conflicting answers to the question “Is this a genuine case of cognitive penetration?”. This hurdle to philosophical and scientific progress can be remedied, I argue, by returning attention to the alleged consequences of the possible phenomenon. There are three: theory-ladenness of perception in contexts of scientific theory choice, a threat to the general epistemic role of perception, and implications for mental architecture. Any attempt to characterize or define, and then empirically test for, cognitive penetration should be constrained by these consequences. This is a method for interpreting and acquiring experimental data in a way that is agreeable to both sides of the cognitive penetration debate. Put crudely, the question shifts to “Is this a cognitive-perceptual relation that results in (or constitutes) one or more of the relevant consequences?” In answering this question, relative to various data, it may turn out that there is no single unified phenomenon of cognitive penetration. But this should be no matter, since it is the consequences that are of central importance to philosophers and scientists alike. (shrink)

The epistemological literature on conspiracy theory has established that strict generalism about conspiracy theories is untenable. This chapter argues, however, that this does not license a move to naive or strict particularism. Rather, any consideration of specific conspiracy claims needs to address conspiracy theory not simply as a formal category of explanation, but as a distinctive social practice, with a history and explanatory repertoire that can give us important, if defeasible, reasons for rejecting at least some such types of claim. (...) These reasons are not merely epistemic. The moral costs of participating in such practices, and of levelling conspiracy accusations in general, generate corresponding ethical requirements for reticence about entertaining conspiracy theories. This doesn’t mean we can retreat to generalism; but it does mean particularism must be governed by a reluctance that, in practice, will rule out a great many conspiracy theory claims as candidates for serious investigation.

Arguing that issues of both emissions and subsistence should be comprehended within a single framework of justice, the proposal here is that this broader framework be developed by reference to the idea of "ecological space.".

The standard mathematical account of the sub-metrical geometry of a space employs topology, whose foundational concept is the open set. This proves to be an unhappy choice for discrete spaces, and offers no insight into the physical origin of geometrical structure. I outline an alternative, the Theory of Linear Structures, whose foundational concept is the line. Application to Relativistic space-time reveals that the whole geometry of space-time derives from temporal structure. In this sense, instead of spatializing time, Relativity temporalizes space.

Truth and Paradox largely consists of three connected technical projects together with a more general account of the nature of truth. The first project is the most familiar: providing an account of how logically complex sentences get assigned truth values on the basis of the truth values assigned to the logically atomic sentences. The second is construction of valid, syntactically specifiable inference rules for a language that includes the familiar logical connectives and the truth predicate. The third is an account (...) of the normative rules governing the assertion of sentences. Let me sketch these in order. (shrink)

Abraham Stone recently has published an argument purporting to show that David Bohm's interpretation of quantum mechanics fails to solve the measurement problem. Stone's analysis is not correct, as he has failed to take account of the conditions under which the theorems he cites are proven. An explicit presentation of a Bohmian measurement illustrates the flaw in his reasoning.

Essential Philosophy of Psychiatry is a concise introduction to the growing field of philosophy of psychiatry. Divided into three main aspects of psychiatric clinical judgement, values, meanings and facts, it examines the key debates about mental health care, and the philosophical ideas and tools needed to assess those debates, in six chapters. In addition to outlining the state of play, Essential Philosophy of Psychiatry presents a coherent and unified approach across the different debates, characterized by a rejection of reductionism and (...) an emphasis on the ineliminability of uncodified skilled judgement. The first part, Values, outlines the debate about whether diagnosis of mental illness is essentially value-laden and argues that the prospects for reducing illness or disease to plainly factual matters are poor. It also explains the important role of skilled contextual judgement, rather than a principles-based deduction, in ethical judgement. The second part, Meanings, examines the central role of understanding and a shared first person perspective, both against attempts to reduce meaning to basic information-processing mechanisms and to explain away the difficulties of understanding psychopathology in recent models of delusion. The third part, Facts, shows the importance of uncodified clinical judgements, both in assessing the validity of psychiatric taxonomy and in the application of Evidence Based Medicine. Despite advances in the codifaction of practice and operationalism of diagnosis, an element of judgement remains in the assessment both of what, at one level, is good evidence for diagnosis and treatment and what, at a higher level, is good evidence for the validity of classification overall.

This paper offers a critical survey and analysis of empirical studies on creativity, with emphasis on how imagination plays a role in the creative process. It takes as a foil the romantic view that, given features like novelty, incubation, and insight, we should be skeptical about the prospects for naturalistic explanation of creativity. It rebuts this skepticism by first distinguishing stages or operations in the creative process. It then works through various behavioral and neural studies, and corresponding philosophical theorizing, that (...) concern the preparation, generation, insight, and evaluation stages of creative processes. The result is not a complete explanation of creativity, but it identifies an explanatory path towards such an explanation, including the features of creativity that motivate that skepticism.

Anthropocentrism can intelligibly be criticised as an ontological error, but attempts to conceive of it as an ethical error are liable to conceptual and practical confusion. After noting the paradox that the clearest instances of overcoming anthropocentrism involve precisely the sort of objectivating knowledge which many ecological critics see as itself archetypically anthropocentric, the article presents the follwoing arguments: there are some ways in which anthropocentrism is not objectionable; the defects associated with anthropocentrism in ethics are better understood as instances (...) of speciesism and human chauvinism; it is unhelpful to call these defects anthropocentrism because there is an ineliminable element of anthropocentrism in any ethic at all; moreover, because the defects do not typically involve a concern with human interests as such, the rhetoric of anti-anthropocentrism is counterproductive in practice.

This chapter concerns the cognitive penetration of the visual experience of colour. Alleged cases of cognitively penetrated colour perception are of special import since they concern an uncontroversial type of visual experience. All theorists of perception agree that colour properties figure properly in the content or presentation of visual perception, even though not all parties agree that pine trees or causes or other "high-level" properties can figure properly in visual content or presentation. So an alleged case of this kind does (...) not require controversial commitments regarding the admissible contents of visual perception. The chapter clarifies this theoretical importance , identifying alleged empirical cases of cognitively penetrated colour perception, and then analyzing the implications of such cases for an epistemology of perception.

ABSTRACT In “Temporal Passage and the ‘No Alternate Possibilities Argument’”, Jonathan Tallant takes up one objection based on the observation that if time passes at the rate of one second per second there is no other possible rate at which it could pass. The argument rests on the premise that if time passes at some rate then it could have passed at some other rate. Since no alternative rate seems to be coherent, one concludes that time cannot pass at all. (...) The obvious weak point of the NAP is the premise itself. (shrink)

Any empirical physical theory must have implications for observable events at the scale of everyday life, even though that scale plays no special role in the basic ontology of the theory itself. The fundamental physical scales are microscopic for the “local beables” of the theory and universal scale for the non-local beables. This situation creates strong demands for any precise quantum theory. This paper examines those constraints, and illustrates some ways in which they can be met.

There is a global shortage of nurses that affects healthcare delivery, which will be exacerbated with the increasing demand for healthcare professionals by the aging population. The growing shortage requires an ethical exploration on the issue of nurse migration. In this article, we discuss how migration respects the autonomy of nurses, increases cultural diversity, and leads to improved patient satisfaction and health outcomes. We also discuss the potential for negative impacts on public health infrastructures, lack of respect for cultural diversity, (...) and ethical concerns related to autonomy and justice, including coercion and discrimination. This analysis is written from a rights-based ethics approach by referring to rights held by nurses and patient populations. Nurse migration highlights conflicts between nurses and between nurses and healthcare systems. Increased awareness of ethical challenges surrounding nurse migration must be addressed to enhance the well-being of nurses and patient populations. (shrink)
