This paper is an enquiry into the logical, metaphysical, and physical possibility of time travel understood in the sense of the existence of closed worldlines that can be traced out by physical objects. We argue that none of the purported paradoxes rule out time travel either on grounds of logic or metaphysics. More relevantly, modern spacetime theories such as general relativity seem to permit models that feature closed worldlines. We discuss, in the context of Gödel's infamous argument for the ideality (...) of time based on his eponymous spacetime, what this apparent physical possibility of time travel means. Furthermore, we review the recent literature on so-called time machines, i.e., of devices that produce closed worldlines where none would have existed otherwise. Finally, we investigate what the implications of the quantum behaviour of matter for the possibility of time travel might be and explicate in what sense time travel might be possible according to leading contenders for full quantum theories of gravity such as string theory and loop quantum gravity.

Ethics is a foundational competency in healthcare inherent in everyday nursing practice. Therefore, the promotion of qualified nurses’ and nursing students’ moral competence is essential to ensure ethically high-quality and sustainable healthcare. The aim of this integrative literature review is to identify the factors contributing to the promotion of qualified nurses’ and nursing students’ moral competence. The review has been registered in PROSPERO (CRD42023386947) and reported according to the PRISMA guideline. Focusing on qualified nurses’ and nursing students’ moral competence, a (...) literature search was undertaken in January 2023 in six scientific databases: CINAHL, Cochrane Library, PsycINFO, PubMed Medline, Scopus and Web of Science. Empirical studies written in English without time limitation were eligible for inclusion. A total of 29 full texts were retrieved and included out of 5233 citations. Quality appraisal was employed using Joanna Briggs Institute checklists and the Mixed Method Appraisal Tool. Data were analysed using inductive content analysis. Research about the factors contributing to the promotion of qualified nurses’ and nursing students’ moral competence is limited and mainly explored using descriptive research designs. The contributing factors were identified as comprising two main categories: (1) human factors, consisting of four categories: individual, social, managerial and professional factors, and ten sub-categories; and (2) structural factors, consisting of four categories: educational, environmental, organisational and societal factors, and eight sub-categories. This review provides knowledge about the factors contributing to the promotion of qualified nurses’ and nursing students’ moral competence for the use of researchers, nurse educators, managers, organisations and policymakers. More research about the contributing factors is needed using complex intervention, implementation and multiple methods designs to ensure ethically sustainable healthcare. (shrink)

In this paper, we present a survey of the development of the technique of argument diagramming covering not only the fields in which it originated - informal logic, argumentation theory, evidence law and legal reasoning – but also more recent work in applying and developing it in computer science and artificial intelligence. Beginning with a simple example of an everyday argument, we present an analysis of it visualised as an argument diagram constructed using a software tool. In the context of (...) a brief history of the development of diagramming, it is then shown how argument diagrams have been used to analyze and work with argumentation in law, philosophy and artificial intelligence.

Reproductive genetic technologies allow parents to decide whether their future children will have or lack certain genetic predispositions. A popular model that has been proposed for regulating access to RGTs is the ‘genetic supermarket’. In the genetic supermarket, parents are free to make decisions about which genes to select for their children with little state interference. One possible consequence of the genetic supermarket is that collective action problems will arise: if rational individuals use the genetic supermarket in isolation from one (...) another, this may have a negative effect on society as a whole, including future generations. In this article we argue that RGTs targeting height, innate immunity, and certain cognitive traits could lead to collective action problems. We then discuss whether this risk could in principle justify state intervention in the genetic supermarket. We argue that there is a plausible prima facie case for the view that such state intervention would be justified and respond to a number of arguments that might be adduced against that view.

This paper explores how fair trade social enterprises manage paradoxes in stakeholder-oriented governance models. We use narrative accounts from board members, at governance events and board documents to report an exploratory study of paradoxes in three FTSEs which are partly farmer-owned. Having synthesized the key social enterprise governance literature and framed it alongside the broader paradox theory, we used narratives to explore how tensions are articulated, how they can be applied within an adapted paradox framework, and how governance actors seek (...) to mitigate paradoxes. The paper contributes to current debates in social enterprise scholarship concerning hybridity :455–476, 2010; in Institutional logics in action, Part B, 2012), hybrid organizing :397–441, 2014) and operational tensions :407–442, 2013) by illustrating empirically how the central social/enterprise paradox manifests in FTSEs governance arrangements. We build on the paradox categories proposed by Lüscher and Lewis :221–240, 2008) and adapted in Smith et al. :407–442, 2013) by developing a recursive model of legitimacy-seeking governance processes, conceptualizing how boards seek to mitigate, but not necessarily resolve, paradoxes.

The intuitions at the core of environmental ethics and of other neglected value realms put pressure on traditional anthropocentric ethics based on monistic value theories. Such pressure is so severe that it has led many to give up on the idea of monistic value theories altogether. I argue that value monism is still preferable to value pluralism and that, indeed, these new challenges are opportunities to vastly improve impoverished traditional theories. I suggest an alternative monistic theory, Richness Theory, and show (...) how it provides an opportunity to capture the needs of both environmental ethics and of our traditional ethics. (shrink)

The phenomenon of technological hazards, whose existence is only revealed many years after they were initially produced, shows that the question of our responsibilities toward future generations is of urgent importance. However, the nature of technological societies means that they are caught in a condition of structural irresponsibility: the tools they use to know the future cannot encompass the temporal reach of their actions. This article explores how dominant legal and moral concepts are equally deficient for helping us understand what (...) future-oriented responsibility requires. An alternative understanding of responsibility is needed, one which can be developed from phenomenological and feminist concepts of care. Care, by opening up for us an understanding of the diversity of values that are constitutive of a worthwhile life, also connects us to the future as the future of care. As such, it provides us with ethical resources that can guide us in the face of uncertainty. (shrink)

Current research on corporate social responsibility (CSR) illustrates the growing sense of discord surrounding the ‘business of doing good’ (Dobers and Springett, Corp Soc Responsib Environ Manage 17(2):63–69, 2010). Central to these concerns is that CSR risks becoming an over-simplified and peripheral part of corporate strategy. Rather than transforming the dominant corporate discourse, it is argued that CSR and related concepts are limited to “emancipatory rhetoric…defined by narrow business interests and serve to curtail interests of external stakeholders.” (Banerjee, Crit Sociol (...) 34(1):52, 2008). The paper addresses gaps in the literature and challenges current thinking on corporate governance and CSR by offering a new conceptual framework that responds to the concerns of researchers and practitioners. The limited focus of existing analyses is extended by a holistic approach to corporate governance and social responsibility that integrates company, shareholder and wider stakeholder concerns. A defensive stance is avoided by delineating key stages of the governance process and aligning profit centred and social responsibility concerns to produce a business-based rationale for minimising risk and mainstreaming CSR.

Is it ethical to market complementary and alternative medicines? Complementary and alternative medicines are medical products and services outside the mainstream of medical practice. But they are not just medicines offered and provided for the prevention and treatment of illness. They are also products and services – things offered for sale in the marketplace. Most discussion of the ethics of CAM has focused on bioethical issues – issues having to do with therapeutic value, and the relationship between patients and those (...) purveyors of CAM. This article aims instead to consider CAM from the perspective of commercial ethics. That is, we consider the ethics not of prescribing or administering CAM but the ethics of selling CAM. (shrink)

A typical theorem of conaexive logics is Aristotle''s Thesis(A), (AA).A cannot be added to classical logic without producing a trivial (Post-inconsistent) logic, so connexive logics typically give up one or more of the classical properties of conjunction, e.g.(A & B)A, and are thereby able to achieve not only nontriviality, but also (negation) consistency. To date, semantical modellings forA have been unintuitive. One task of this paper is to give a more intuitive modelling forA in consistent logics. In addition, while inconsistent (...) but nontrivial theories, and inconsistent nontrivial logics employing prepositional constants (for which the rule of uniform substitution US fails), have both been studied extensively within the paraconsistent programme, inconsistent nontrivial logics (closed under US) do not seem to have been. This paper gives sufficient conditions for a logic containingA to be inconsistent, and then shows that there is a class of inconsistent nontrivial logics all containingA. A second semantical modelling forA in such logics is given. Finally, some informal remarks about the kind of modellingA seems to require are made. (shrink)

Many of the existing ethical analyses of genetic engineering technologies (GET) focus on how they can be used to enhance individuals—to improve individual well-being, health and cognition. There is a gap in the current literature about the specific ways enhancement technologies could be used to improve our populations and species, viewed as a whole. In this paper, I explore how GET may be used to enhance the species through improvements in the gene pool. I argue one aspect of the species (...) that may be desirable to enhance is ‘persistence’ or long-term viability. I then look at some of the ways in which GET could be used to improve human persistence and argue that the use of GET to secure benefits for individuals may compromise persistence. This suggests conflicts between uses of GET to enhance individuals and uses to promote the persistence of the species may occur. As GET are further developed, the likelihood that these conflicts will actually arise, and how we should resolve them if they do, will need to be considered. (shrink)

We respond to Moses Pava’s defense of the “Triple Bottom Line” (3BL) concept against our earlier criticisms. We argue that, pacePava, the multiplicity of measures (and units of measure) that go into evaluating ethical performance cannot reasonably be compared to the handful of standard methods for evaluating financial performance. We also question Pava’s claim that usage of the term “3BL” is somehow intended to be ironical or subversive.

Many recent attacks on consequentialism and several defenses of pluralism have relied on arguments for the incommensurability of value. Such arguments have, generally, turned on empirical appeals to aspects of our everyday experience of value conflict. My intention, largely, is to bypass these arguments and turn instead to a discussion of the conceptual apparatus needed to make the claim that values are incommensurable. After delineating what it would mean for values to be incommensurable, I give an a priori argument that (...) such is impossible. It is widely accepted that value is conceptually tied to desire. I argue that, more specifically, it is proportional to merited desire strength. This connection gives one a metric of all value if there is any such thing. This metric entails that value is a complete ordering over all states of affairs, or, in other words, that value is commensurable. (shrink)

Palaeontology developed as a field dependent upon comparison. Not only did reconstructing the fragmentary records of fossil organisms and placing them within taxonomic systems and evolutionary lineages require detailed anatomical comparisons with living and fossil animals, but the field also required thinking in terms of behavioural, biological and ecological analogies with modern organisms to understand how prehistoric animals lived and behaved. Yet palaeontological material often worked against making easy linkages, bringing a sense of mystery and doubt. This paper will look (...) at an animal whose study exemplified these problems: the Chalicothere. Increasingly recognized as a specific type from finds across North America and Eurasia from the early nineteenth century onwards, these prehistoric mammals showed short back legs terminating in pawed feet, long front limbs ending in sharp claws, a long flexible neck, and herbivorous grinding teeth. The Chalicothere became a significant organism within palaeontological studies, as the unexpected mix of characters made it a textbook example against the Cuvierian notion of “correlation of parts,” while explaining how the animal moved, fed and behaved became puzzling. However, rather than prevent comparisons, these actually led to comparative analogies becoming flexible and varied, with different forms of comparison being made with varying methods and degrees of confidence, and with the anatomy, movement and behaviour of giraffes, bears, horses, anteaters, primates and other organisms all serving at various points as potential models for different aspects of the animal. This paper will examine some of the attempts to reconstruct and define the Chalicotheres across a long timescale, using this to show how multiple comparisons and analogies could be deployed in a reconstructive and evolutionary science like palaeontology, and illustrate some of the limits and tensions in comparative methods, as they were used to reconstruct organisms which were thought to be incomparable to any modern animal.

The Peking Man fossils discovered at Zhoukoudian in north-east China in the 1920s and 1930s were some of the most extensive palaeoanthropological finds of the twentieth century. This article examines their publicization and discussion in Britain, where they were engaged with by some of the world's leading authorities in human evolution, and a media and public highly interested in human-origins research. This international link – simultaneously promoted by scientists in China and in Britain itself – reflected wider debates on international (...) networks; the role of science in the modern world; and changing definitions of race, progress and human nature. This article illustrates how human-origins research was an important means of binding these areas together and presenting scientific work as simultaneously authoritative and credible, but also evoking mystery and adventurousness. Examining this illustrates important features of contemporary views of both science and human development, showing not only the complexities of contemporary regard for the international and public dynamics of scientific research, but wider concerns over human nature, which oscillated between optimistic notions of unity and progress and pessimistic ones of essential differences and misdirected development.

Nanotechnologies are enabling technologies which rely on the manipulation of matter on the scale of billionths of a metre. It has been argued that scientific uncertainties surrounding nanotechnologies and the inability of regulatory agencies to keep up with industry developments mean that voluntary regulation will play a part in the development of nanotechnologies. The development of technological applications based on nanoscale science is now increasingly seen as a potential test case for new models of regulation based on future-oriented responsibility, lifecycle (...) risk management, and upstream public engagement. This article outlines findings from a project undertaken in 2008–2009 for the UK Government’s Department of Environment, Food and Rural Affairs (DEFRA) by BRASS at Cardiff University, involving an in-depth survey both of current corporate social responsibility (CSR) reporting in the UK nanotechnologies industry, and of attitudes to particular stakeholder issues within the industry. The article analyses the results to give an account of the nature of corporate social performance (CSP) within the industry, together with the particular model of CSR operating therein (‘do no harm’ versus ‘positive social force’). It is argued that the nature of emerging technologies requires businesses to adopt particular visions of CSR in order to address stakeholder issues, and that the nanotechnologies industry presents specific obstacles and opportunities in this regard.

The Trompenaars database (1993) updated with Hampden-Turner (1998) has been assembled to help managers structure their cross cultural experiences in order to develop their competence for doing business and managing across the world. The database comprises more than 50,000 cases from over 100 countries and is one of the world's richest sources of social constructs. Woolliams and Trompenaars (1998) review the analysis undertaken by the authors in the last five years to develop the methodological approach underpinning the work. Recently Trompenaars (...) with Hampden-Turner (Trompenaars and Woolliams, 1999) have extended the concepts into a new model on dilemma reconciliation of cultural differences. This paper reviews these latest updates in relation to dilemmas of cross-cultural business ethics. The paper asserts that knowledge in relation to business ethics is culturally specific; and that ethnocentrism is not easy to avoid. Too great an emphasis on rational-analytic conceptions of reality may mean that syntheses, emotion, and intuition, are not adequately developed. This presents implications for doing business and managing across cultures and for resolving ethical dilemmas. (shrink)

The question of the interpretation of impossible pictures is taken up. Penrose's account is reviewed. It is argued that whereas this account makes substantial inroads into the problem, there needs to be a further ingredient. An inconsistent account using heap models is proposed.

While earlier work has emphasized Kant’s philosophy of religion as thinly disguised morality, this timely and original reappraisal of Kant’s philosophy of religion incorporates recent scholarship. In this volume, Chris L. Firestone, Stephen R. Palmquist, and the other contributors make a strong case for more specific focus on religious topics in the Kantian corpus. Main themes include the relationship between Kant’s philosophy of religion and his philosophy as a whole, the contemporary relevance of specific issues arising out of Kant’s (...) philosophical theology, and the relationship of Kant’s philosophy to Christian theology. As a whole, this book capitalizes on contemporary movements in Kant studies by looking at Kant not as an anti-metaphysician, but as a genuine seeker of spirituality in the human experience. (shrink)

Popper's definition looked initially promising provided that the restriction of classical logic was removed. As we have seen, this promise is not fulfilled. The search for a satisfactory verisimilitude ordering must therefore be pursued along more mainstream lines. The present exercise ought, however, to make us aware of the possibility that breakdowns of proposed definitions might only occur because of strictly classical assumptions.

This essay examines the Mission paléontologique française of the 1920s, a series of scientific expeditions into the Ordos Desert in Inner Mongolia in which a team of Jesuit scholar-scientists worked with local collaborators to provide material for the Muséum d’Histoire Naturelle in Paris. The case study shows that the global and colonial expansion of Western science in the early twentieth century provided space for traditional scientific institutions, such as universalizing metropolitan collections and clerical scholarly networks, to extend their research projects. (...) The linking of approaches, agendas, and geographic regions was facilitated by the concepts and practices of the deep-time sciences of geology, paleontology, and human prehistory. These were based on the interchange of expertise, common projects of unveiling the development of life, and the alignment of different regions and specimens. Moreover, the expeditions did not just conduct research based around global movement and transmission. They also conceptualized the ancient development of life in terms of movement, migration, and exchange. The act of forming research networks that linked Asia and Europe also led scientists to conceive of these regions as bound by deep natural processes. Circulation and transfer became important actors’ categories used to understand the origins and history of life. (shrink)

In this article we address the question of how many impossible images Escher produced. To answer requires us first to clarify a range of concepts, including content, ambiguity, illusion, and impossibility. We then consider, and reject, several candidates for impossibility before settling on an answer.

This paper offers an inconsistent model of motion perception. It was prompted by work on inconsistent motion due to Hegel and, following him, Priest. But the paper skirts Hegel's full scale idealism, by proposing that the inconsistency is with the cognitive contents of motion perception. The paper draws on work in the psychology of perception, and in the theory of inconsistency. I begin by noting the prima facie argument that temporal change threatens inconsistency, and canvassing ways in which this might (...) be avoided. The orthodox reply to the prima facie argument is that one and the same thing can have different incompatible properties at different times. This is plausible when applied to motion in the physical world. However, applied to cognition, it can be seen that the phenomenon of phi or beta, combined with the mechanism of a Reichardt detector, lends support to one key step in the prima facie argument, namely re-identification over time. The inconsistency of the model is then seen to follow from application of the Fade Principle. Advantages of the model are stressed: including a simple explanation of the debilitating condition of akinetopsia, that is, motion blindness; and a suggestion as to how to account for the “moving now.”.

_ The Subject of Human Being_ discusses the basic powers of human kind arising from the foundation of the biological brain and manifesting in extraordinary psychological and social capacities and developments. The book consolidates theoretical insights into social ontology from several thinkers, whose profound advances toward understanding the relationship between individuals and society ought to revolutionize social theory as understood and practiced in the social sciences and humanities. Drawing from critical realist social theory developed by Bhaskar and Margaret Archer, John (...) Searle’s philosophy of mind and social ontology, Husserlean and Sartrean phenomenology of consciousness, and Lacanian and existential psychoanalytic theory, the book seeks to portray a unified social ontology that is materialist, emergent, realist, dialectical, processual, and liberatory. Offering a dialectical and progressive view of human being to counter the forces of exploitation and division inflicted on human kind and the ecosystems in which we reside, this book is essential reading for students and scholars of critical realism, philosophy and sociology.

Modern health care rhetoric promotes choice and individual patient rights as dominant values. Yet we also accept that in any regime constrained by finite resources, difficult choices between patients are inevitable. How can we balance rights to liberty, on the one hand, with equity in the allocation of scarce resources on the other? For example, the duty of health authorities to allocate resources is a duty owed to the community as a whole, rather than to specific individuals. Macro-duties of this (...) nature are founded on the notion of equity and fairness amongst individuals rather than personal liberty. They presume that if hard choices have to be made, they will be resolved according to fair and consistent principles which treat equal cases equally, and unequal cases unequally.In this paper, we argue for greater clarity and candour in the health care rights debate. With this in mind, we discuss (1) private and public rights, (2) negative and positive rights, (3) procedural and substantive rights, (4) sustainable health care rights and (5) the New Zealand booking system for prioritising access to elective services. This system aims to consider: individual need and ability to benefit alongside the resources made available to elective health services in an attempt to give the principles of equity practical effect. We describe a continuum on which the merits of those, sometimes competing, values—liberty and equity—can be evaluated and assessed. (shrink)

This essay takes a hard look at the current state of much academic (mainly analytic) philosophy and sets out to diagnose where things have gone wrong. It offers a sharply critical assessment of the prevailing narrowness, cliquishness, linguistic inertness, like-mindedness, intellectual caution, misplaced scientism, over-specialisation, guild mentality, lack of creative or inventive flair, and above all the self-perpetuating structures of privilege and patronage that have worked to produce this depressing situation. On the constructive side I suggest how a belated encounter (...) with developments beyond its cultural-professional horizons continental might bring large (and reciprocal) benefits. I also offer some tentative ideas as to what could or should mean as applied to philosophical thinking and writing. (shrink)

A second-person approach that prioritizes dyadic emotional interaction is not well equipped to explain the origins of the understanding of mind conceived as intentionality. Instead, the critical elements that will deliver the understanding of self and other as persons with intentionality are shared object-centered interactions that include not only emotional engagement, but also joint attention and joint goal-directed action.

In more precise terms, ecofeminism stresses the depth to which human realities are embedded in ecological realities, and the fact that we are all composed of physical and conceptual connections and relationships. Ecofeminists also make strong normative claims about those connections, and they find present ecological and social relationships to be far more morally troubling than "we" modern thinkers tend to acknowledge.Karen Warren's work has been incredibly influential in the development of ecofeminism, especially as a philosophical perspective. In her 1987 essay "Feminism and Ecology: Making Connections," she argued for a basic ecofeminist position: that feminists ought to pay attention to environmental issues and ecological interdependencies, and that environmentalists ought to attend to the connections among ecological degradation, sexism, and other forms of social oppression. A wealth of ecofeminist poetry, fiction, and political writing had been published in the seventies and early eighties, before "Feminism and Ecology" appeared on the pages of [End Page 1] the journal Environmental Ethics. But Karen Warren was the among the first to use the tools of analytic philosophy to articulate and argue for ecofeminism as a philosophical position, ethical approach, and political movement.In fact, Mary Daly's Gyn/Ecology: The Metaethics of Radical Feminism (1978) was arguably the first work in contemporary academic philosophy to engage ecofeminism (my first acquaintance with ecofeminist theory was made through a special issue of the feminist magazine Heresies, on feminism and ecology). But Daly's emphasis was on the plight of females in patriarchal social environments. Karen Warren and Australian philosopher Val Plumwood brought full focus to the eco in ecofeminism, applying feminist philosophy (and especially feminist ethics) to our relations with the more than human world, and in turn articulating a broader theory of oppression and liberation. Their analytic approaches resulted in philosophy that synthesizes as it clarifies, taking seriously the value of nature, the history of philosophy, the power of culture, and the insights of good science.In Ecofeminist Philosophy Karen Warren presents ecofeminism as a general school of thought, though she also argues for a particular set of ecofeminist principles, values, methodologies, and practices. In terms of both her method and her conclusions, it is important to note that her emphasis on clearly articulated principles is by no means a defense of an absolutist or falsely universalizing ethic. Rather, Warren's ecofeminist philosophy emerges from her reading of a wide and diverse array of theoretical and political examples. Like Noël Sturgeon's Ecofeminist Natures: Race, Gender, Feminist Theory and Political Action (1997), which focuses on feminist ecological movements, Warren's project is to look for and describe the family resemblances among diverse examples of ecofeminism. This approach allows her to articulate epistemic, moral, and political positions that are pluralist, yet do not avoid making bold truth-claims. For example, Warren argues that "something is a feminist issue if an understanding of it helps one understand the oppression, subordination, or domination of women" (Warren 2000, 1).In a sense such a definition is wide open, taking various approaches and issues to be worthy of feminist attention. At the same time, it certainly does not allow just any perspective to count as feminist. Throughout Ecofeminist Philosophy, Warren defends multicultural ethics while clearly advocating specific transcultural values, such as justice and caring: [End Page 2] If we dare to care, if we dare to enter into community with others through an honest recognition of our commonalities and differences, we will be poised to create generally respectful, nonviolent, care-based, intentional communities where commonalities and differences are just that...

This paper aims to distinguish and classify sixteen versions of the Necker cube. In particular, it is shown how to describe inconsistent and incomplete theories which correspond in a systematic way to these sixteen diagrams. Concerning two of these sixteen cubes, there is a natural intuition that there is a sense in which they inconsistent. It is seen that this intuition is vindicated by an analysis in which their corresponding theories turn out to be globally inconsistent but not locally inconsistent, (...) while various other cubes of the sixteen are merely locally inconsistent. The Routley functor is seen to be useful in classifying the relations between these diagrams. (shrink)
