Words change meaning over time. Some meaning shift is accompanied by a corresponding change in subject matter; some meaning shift is not. In this paper I argue that an account of linguistic meaning can accommodate the first kind of case, but that a theory of concepts is required to accommodate the second. Where there is stability of subject matter through linguistic change, it is concepts that provide the stability. The stability provided by concepts allows for genuine disagreement and ameliorative change (...) in the context of conceptual engineering. (shrink)

The increasing workplace use of artificially intelligent (AI) technologies has implications for the experience of meaningful human work. Meaningful work refers to the perception that one’s work has worth, significance, or a higher purpose. The development and organisational deployment of AI is accelerating, but the ways in which this will support or diminish opportunities for meaningful work and the ethical implications of these changes remain under-explored. This conceptual paper is positioned at the intersection of the meaningful work and ethical AI (...) literatures and offers a detailed assessment of the ways in which the deployment of AI can enhance or diminish employees’ experiences of meaningful work. We first outline the nature of meaningful work and draw on philosophical and business ethics accounts to establish its ethical importance. We then explore the impacts of three paths of AI deployment (replacing some tasks, ‘tending the machine’, and amplifying human skills) across five dimensions constituting a holistic account of meaningful work, and finally assess the ethical implications. In doing so we help to contextualise the meaningful work literature for the era of AI, extend the ethical AI literature into the workplace, and conclude with a range of practical implications and future research directions.

This paper argues that just as full beliefs can constitute knowledge, so can properties of your credence distribution. The resulting notion of probabilistic knowledge helps us give a natural account of knowledge ascriptions embedding language of subjective uncertainty, and a simple diagnosis of probabilistic analogs of Gettier cases. Just like propositional knowledge, probabilistic knowledge is factive, safe, and sensitive. And it helps us build knowledge-based norms of action without accepting implausible semantic assumptions or endorsing the claim that knowledge is interest-relative.

I use the psychological phenomenon of ‘attribute framing’ as a case study for exploring philosophical conceptions of semantics and the semantics-pragmatics divide. Attribute frames are pairs of sentences that use contradictory expressions to predicate the same property of an individual or object. Despite their equivalence, pairs of attribute frames have been observed to induce systematic variability in hearers’ responses. One explanation of such framing effects appeals to the distinct ‘reference point information’ conveyed by alternative frames. Although this information is taken (...) to be pragmatic, a live debate in the philosophy of language concerns the extent to which pragmatic information can really be held apart from semantics. Therefore, in this article I examine whether – and how – reference point information might be thought to intrude on the semantics of an attribute frame. I describe two ways in which the information might be considered broadly semantic, due to its being directly communicated or conventional. However, I argue that the framing data in fact support a narrower conception of semantics, and a semantics-pragmatics distinction that separates standing sentence meaning from enriched communicated meaning.

Confabulation is a symptom central to many psychiatric diagnoses and can be severely debilitating to those who exhibit the symptom. Theorists, scientists, and clinicians have an understandable interest in the nature of confabulation—pursuing ways to define, identify, treat, and perhaps even prevent this memory disorder. Appeals to confabulation as a clinical symptom rely on an account of memory’s function from which cases like the above can be contrasted. Accounting for confabulation is thus an important desideratum for any candidate theory of (...) memory. Many contemporary memory theorists now endorse Constructivism, where memory is understood as a capacity for constructing plausible representations of past events. Constructivism’s aim is to account for and normalize the prevalence of memory errors in everyday life. Errors are plausible constructions that, on a particular occasion have led to error. They are not, however, evidence of malfunction in the memory system. While Constructivism offers an uplifting repackaging of the memory errors to which we are all susceptible, it has troubling implications for appeals to confabulation in psychiatric diagnosis. By accommodating memory errors within our understanding of memory’s function, Constructivism runs the risk of being unable to explain how confabulation errors are evidence of malfunction. After reviewing the literature on confabulation and Constructivism, respectively, I identify the tension between them and explore how different versions of Constructivism may respond. The paper concludes with a proposal for distinguishing between kinds of false memory—specifically, between misremembering and confabulation—that may provide a route to their reconciliation. (shrink)

In this article, I seek to address an aspect of the general inattention to miscarriage by examining a pressing topic: the moral meanings of pregnancy loss. I focus primarily on the import of such meanings for women in their ethical relationship with themselves, while also finding significant the meaning of miscarriage in community, that is, for our shared moral lives. Exploring miscarriage as a moral phenomenon is critical for figuring out miscarriage’s impact on our ethical self-conception—on how we understand ourselves (...) as moral agents—and in forming and deforming how we understand one another in the broader context of our moral communities—in intimate realms, in public realms, and in various realms in between. -/- I begin by articulating the need for a dedicated perinatal ethics, then developing an overview of this approach. It is against this backdrop that miscarriage’s complex moral meaning can best emerge. I then consider a few promising yet problematic concepts for comprehending the moral meanings of miscarriage, including moral agency, reactive attitudes (in this case, betrayal and guilt), moral responsibility, and moral standing.

The third edition of this popular book has been updated to take account of the latest developments in policy and social work practice. It includes new sections on radical/emancipatory and postmodern approaches to ethics, analysis of the latest codes of ethics from over 30 different countries, additional case studies of ethical problems and dilemmas, practical exercises, and annotated further reading lists at the end of each chapter.

The present paper focuses on essentialism about natural kinds as a case study in order to illustrate this more general point. Saul Kripke and Hilary Putnam famously argued that natural kinds have essences, which are discovered by science, and which determine the extensions of our natural kind terms and concepts. This line of thought has been enormously influential in philosophy, and is often taken to have been established beyond doubt. The argument for the conclusion, however, makes critical use of intuitions, (...) and I note that the intuitions are of the sort had by preschool children, and that they are traceable to a deep-seated cognitive outlook, which is often called “psychological essentialism.” Further, if we did not have such a cognitive outlook or implicit belief set—a belief set which is in fact in place by at least age 4—then we would not have the relevant philosophical intuitions. In light of this, I consider the question of whether natural kinds actually have scientifically discovered or discoverable essences, and whether these putative essences could determine the extensions of our terms and concepts as Kripke, Putnam, and many others have supposed. In fact, a number of philosophers of biology and chemistry have argued that biological and chemical kinds do not have such essences, yet these arguments—particularly in the case of chemistry—have not been assimilated by philosophers more generally. The reason for this poor assimilation is, I suggest, that the Kripke/Putnam view is just so intuitive. But this fact, I argue, is due to a deep-seated cognitive bias, rather than to any special insight into the nature of reality. (shrink)

Drawing on recent research in the philosophy of the emotions and empirical evidence from social psychology, this paper argues that the concept of loss of self-control at common law mischaracterises the relationship between the emotions and their effects on action. Emotions do not undermine reason in the ways offenders describe ; nor do they compel people to act in ways they cannot control. As such, the idea of ‘loss of self-control’ is an inaccurate and misleading description of the psychological mechanisms (...) at play in cases of emotionally motivated killing, where there may not be any ‘loss of self-control’ as such.

The psychological contract refers to the implicit and subjective beliefs regarding a reciprocal exchange agreement, predominantly examined between employees and employers. While contemporary contract research is investigating a wider range of exchanges employees may hold, such as with team members and clients, it remains silent on a rapidly emerging form of workplace relationship: employees’ increasing engagement with technically, socially, and emotionally sophisticated forms of artificially intelligent (AI) technologies. In this paper we examine social robots (also termed humanoid robots) as likely (...) future psychological contract partners for human employees, given these entities transform notions of workplace technology from being a tool to being an active partner. We first overview the increasing role of robots in the workplace, particularly through the advent of sociable AI, and synthesize the literature on human–robot interaction. We then develop an account of a human-social robot psychological contract and zoom in on the implications of this exchange for the enactment of reciprocity. Given the future focused nature of our work we utilize a thought experiment, a commonly used form of conceptual and mental model reasoning, to expand on our theorizing. We then outline potential implications of human-social robot psychological contracts and offer a range of pathways for future research. (shrink)

Using artificial intelligence (AI) to make decisions in human resource management (HRM) raises questions of how fair employees perceive these decisions to be and whether they experience respectful treatment (i.e., interactional justice). In this experimental survey study with open-ended qualitative questions, we examine decision making in six HRM functions and manipulate the decision maker (AI or human) and decision valence (positive or negative) to determine their impact on individuals’ experiences of interactional justice, trust, dehumanization, and perceptions of decision-maker role appropriate- (...) ness. In terms of decision makers, the use of human decision makers over AIs generally resulted in better perceptions of respectful treatment. In terms of decision valence, people experiencing positive over negative decisions generally resulted in better perceptions of respectful treatment. In instances where these cases conflict, on some indicators people preferred positive AI decisions over negative human decisions. Qualitative responses show how people identify justice concerns with both AI and human decision making. We outline implications for theory, practice, and future research. (shrink)

This article outlines and develops the concept of ‘ethics work’ in social work practice. It takes as its starting point a situated account of ethics as embedded in everyday practice: ‘everyday ethics’. This is contrasted with ‘textbook ethics’, which focuses on outlining general ethical principles, presenting ethical dilemmas and offering normative ethical frameworks (including decision-making models). ‘Ethics work’ is a more descriptive account of ethics that refers to the effort people put into seeing ethically salient aspects of situations, developing themselves (...) as good practitioners, working out the right course of action and justifying who they are and what they have done. After identifying seven features of ethics work, including work on framing, roles, emotion, identity, reason, relationships and performance, each element is illustrated with reference to two case examples from social work practice. It is argued that the concept of ethics work, with its focus on the practitioners as moral agents in context, is an important antidote to the rules-based managerialism of much contemporary practice.

Too often, hope is described in individualist terms and in ways that do not help us understand contemporary democracy or offer ways to improve it. Instead, I develop an account of hope situated within pragmatist philosophy that is rooted in the experiences of individuals and grows out of real life circumstances, yet cannot be disconnected from social and political life. This account can help us to better face current political struggles related to hopelessness and despair, all the while building democratic (...) identity. To examine the ways in which shared hoping and the content of our hopes shape our identity and our work together in democracy, I consider both how and what we hope in political contexts. (shrink)

As a number of high profile companies have found to their cost, corporate reputations can be significantly affected by firms' management of sustainability issue, including those that are outside their direct control, such as the environmental and social impacts of their supply networks. This paper begins by examining the relationship between corporate social responsibility, reputation, and supply network conditions. It then looks at the effectiveness of one tool for managing supply network sustainability issues, ethical sourcing codes of conduct, by examining (...) how the characteristics of three supply networks branded clothes, DIY wood products and branded confectionary affects the implementation ethical sourcing codes of conduct. It ends by setting out conclusions on why implementation of such codes has been so much more successful in some sectors than others and recommendations on effective approaches to managing sustainability issues in supply networks.

In a series of recent articles, Robin Jeshion has developed a theory of singular thought which she calls ‘cognitivism’. According to Jeshion, cognitivism offers a middle path between acquaintance theories—which she takes to impose too strong a requirement on singular thought, and semantic instrumentalism—which she takes to impose too weak a requirement. In this article, I raise a series of concerns about Jeshion's theory, and suggest that the relevant data can be accommodated by a version of acquaintance theory that distinguishes (...) unsuccessful thoughts of singular form from successful singular thoughts, and in addition allows for ‘trace-based’ acquaintance.

This paper argues that several leading theories of subjunctive conditionals are incompatible with ordinary intuitions about what credences we ought to have in subjunctive conditionals. In short, our theory of subjunctives should intuitively display semantic humility, i.e. our semantic theory should deliver the truth conditions of sentences without pronouncing on whether those conditions actually obtain. In addition to describing intuitions about subjunctive conditionals, I argue that we can derive these ordinary intuitions from justified premises, and I answer a possible worry (...) for my derivation by refuting a subjunctive triviality result modeled on (Lewis 1976). I conclude that the debate over the correct theory of subjunctive conditionals requires settling meta-philosophical questions about the relative value of various virtues of first-order theories of subjunctive conditionals.

Artificially intelligent (AI) technologies are increasingly being used in many workplaces. It is recognised that there are ethical dimensions to the ways in which organisations implement AI alongside, or substituting for, their human workforces. How will these technologically driven disruptions impact the employee–employer exchange? We provide one way to explore this question by drawing on scholarship linking Integrative Social Contracts Theory (ISCT) to the psychological contract (PC). Using ISCT, we show that the macrosocial contract’s ethical AI norms of beneficence, non-maleficence, (...) autonomy, justice, and explicability can feed into national- and organisational-level microsocial contracts. We also outline the role of employees’ technology frames in this process. We then use an illustrative example to demonstrate how this multilevel normative background helps to inform the content of individuals’ PCs in the context of working with AI technologies. (shrink)

Among the many practical failures that threaten us, weakness of will or akrasia is often considered to be a paradigm of irrationality. The eleven new essays in this collection, written by an excellent international team of philosophers, some well-established, some younger scholars, give a rich overview of the current debate over weakness of will and practical irrationality more generally. Issues covered include classical questions such as the distinction between weakness and compulsion, the connection between evaluative judgement and motivation, the role (...) of emotions in akrasia, rational agency, and the existence of the will. The also include new topics, such as group akrasia, strength of will, the nature of correct choice, the structure of decision theory, the temporality of prudential reasons, and emotional rationality. Because these questions cut across philosophy of mind and ethics, the collection will be essential reading for scholars, postgraduates, and upper-level undergraduates in both these fields. (shrink)

How do we know what our intentions are? It is argued that work on self-knowledge has tended to neglect the attitude of intention, and that an epistemological account is needed that is attuned to the specific features of that state. Richard Moran’s Authorship view, on which we can acquire self-knowledge by making up our minds, offers a promising insight for such an account: we do not normally discover what we intend through introspection. However, his formulation of the Authorship view, developed (...) primarily with the attitude of belief in mind, is found wanting when applied to intention. An alternative account is proposed for knowledge of one’s own intentions that gives a central role to the mental act of deciding what to do. It is argued that we can come to know what we intend by making a decision about what to do and self-ascribing the content of that decision as our intended action. (shrink)

It is commonly held that Wittgenstein abandoned the Tractatus largely because of a problem concerning color incompatibility. My aim is to solve this problem on Wittgenstein’s behalf. First I introduce the central program of the Tractatus (§1) and the color incompatibility problem (§2). Then I solve the problem without abandoning any Tractarian ideas (§3), and show that given certain weak assumptions, the central program of the Tractatus can in fact be accomplished (§4). I conclude by distinguishing my system of analysis (...) from others and by explaining the historical underpinnings of my understanding of the nature of elementary propositions (§5). (shrink)

This book explores the far-reaching ethical implications of recent changes in the organization and practice of the social professions, including social work, community and youth work. Drawing on moral philosophy, professional ethics and new empirical research, the author explores such questions as: * Can any occupation justifiably claim a special set of ethics? * What is the impact of the new 'ethics of distrust' on the autonomy discretion and creativity of practitioners? * How does inter-professional working challenge conceptions of professional (...) identities and roles? * Do 'professional ethics' act as an obstruction to constructive developments? Combing interviews with practitioners with developments in ethical theory, Ethics, Accountability and the Social Professions shows the complexity and range of issues at stake. (shrink)

In this paper, we theorize that the anticipation of guilt plays an important role in ethically questionable consumer situations. We propose an ethical decision-making framework incorporating anticipated guilt as partial mediator between consumers’ ethical beliefs (anteceded by ethical ideology) and intentions. In the first study, we compared several models using structural equation modeling and found empirical support for our research model. A second experiment was set up to illustrate how these new insights may be applied to prevent consumers from taking (...) advantage of the seller. Results showed that enhancing the anticipation of guilt (by making the interpersonal consequences of the unethical act more salient) increased consumers’ ethical intentions, controlling for ethical beliefs. Together these two studies might have important theoretical and managerial contributions. (shrink)

This chapter explores the practice of Body Weather (BW), a postmodern dance methodology, addressing how BW performers experience and enact agency in this context of practice. Adopting a cognitive ecological, ethnographic, and phenomenological approach, this work focuses on the creation of AURA NOX ANIMA (2016) – a short dance film directed by Sydney-based visual artist Lux Eterna and filmed on the sandy dunes in Anna Bay, New South Wales, Australia – to underscore the role played by the physical and cultural (...) environment in shaping BW performers’ sense of agency. Through the analysis of salient features of BW methodology, that include the practice of bisoku, slow movement, and the cultivation of an attention to the changing ‘weather’ of the performance ecology, this chapter suggests an ecological notion of agency as a key concept in the study of embodied cognition in performance. The chapter emphasises the relevance of addressing the environment-culture-context situatedness in the study of performance practices. (shrink)

Although it is now widely acknowledged that Hegel’s political philosophy is based freedom, there is still divided opinion regarding the role of conscience within Hegel’s Philosophy of Right. In fact, it is often claimed that Hegel allows insufficient room for conscience within the political realm he describes. This article responds to such criticism and argues that Hegel allocates an irreducible function for conscience within his political state. It begins by examining the emergence of conscience within the morality section of the (...) text and then continues to establish what happens to the conscience during the Aufhebung of morality into ethical life . It argues that, during this dialectical transition, all the essential moments of moral conscience are preserved in the true conscience of ethical life. This article puts forward a reading of true ethical conscience that combines its right to subjective reflection alongside its respect for objective institutions, thus demonstrating that conscience can operate as a meaningful part of Hegel’s political state.

The goal of this paper is both modest and ambitious. The modest goal is to show that intercountry adoption should be considered by ethicists and healthcare providers. The more ambitious goal is to introduce the many ethical issues that intercountry adoption raises. Intercountry adoption is an alternative to medical, assisted reproduction option such as in vitro fertilization (IVF), intracytoplasmic sperm injection, third party egg and sperm donation and surrogacy. Health care providers working with assisted reproduction are in a unique position (...) to introduce their clients to intercountry adoption; however, providers should only do so if intercountry adoption is ethically equal or superior to the alternatives. This paper first presents a brief history of intercountry adoption. The second section compares intercountry adoption with medical alternatives. The third section examines the unique ethical challenges that are not shared by other medical alternatives. The final section concludes that it is simplistic for a healthcare provider to promote intercountry adoption unconditionally; however, in situation where intercountry adoption is practiced conscientiously it poses no greater ethical concern than several medical alternatives. This conclusion is preliminary and is intended as a start for further discussion. (shrink)

This commentary explores a few of the common threads in a symposium of obesity narratives in light of the American Medical Association’s classification of obesity as a disease. While the narratives illustrate the breadth of experiences, they each highlight the absence of a clear approach for the treatment of obesity, as well as the lack of conversation and compassion in the most basic of interactions with medical professionals. This could be cause for despair, yet we learn through these shared experiences (...) that we can take control of our care and plot a course for real and lasting assistance with this condition.

The World Trade Organization has faced many criticisms from human rights and social justice advocates. And yet it is difficult to identify direct clashes between WTO obligations and human rights obligations. Nevertheless, as demonstrated in this article, the concerns of WTO critics are justifiable, for example in the areas of the organisation's democratic deficit, the effect of its rules on developing States, and in the arena of labour rights. The criticisms are not, as it were, manifestations of mere 'regime envy' (...) by social justice constituencies. Indeed, the present imbalance in effectiveness between international economic institutions and international social justice institutions must be redressed.

The tension between organizational values and the operation of aged care as a business is often characterized as the “mission versus margin” dilemma. It is common across the industry in both not-for-profit and for-profit organizations. However, in for-profit aged care facilities, there is no question about the intention to make a profit or the purpose of the profits. This is not so clear in not-for-profit aged care organizations. This article explores the tension through the examination of a detailed case study (...) of one of the larger not-for-profit social service organizations—All Saints Christian Care. It analyses the culture and managerial decisions though the lens of the political philosophy value pluralism. Finally, based on the value-plural theory, recommendations are made that would create greater operational transparency in not-for-profit aged care service. (shrink)

My doctoral project is a study of epistemological and ethical issues in Evidence-Based Medicine, a movement in medicine which emphasizes the use of randomized controlled trials. Much of the research on EBM suggests that, for a large part of the movement's history, EBM considered expertise, mechanisms, and values to be forces contrary to its goals and has sought to remove them, both from medical research and from the clinical encounter. I argue, however, that expertise, mechanisms and values have important epistemological (...) and ethical roles to play and can be incorporated into the current EBM movement. (shrink)

Artificial intelligence is increasingly inputting into various human resource management functions, such as sourcing job applicants and selecting staff, allocating work, and offering personalized career coaching. While the use of AI for such tasks can offer many benefits, evidence suggests that without careful and deliberate implementation its use also has the potential to generate significant harms. This raises several ethical concerns regarding the appropriateness of AI deployment to domains such as HRM, which directly deal with managing sometimes sensitive aspects of (...) individuals’ employment lifecycles. However, research at the intersection of HRM and technology continues to largely center on examining what AI can be used for, rather than focusing on the salient factors relevant to its ethical use and examining how to effectively engage human workers in its use. Conversely, the ethical AI literature offers excellent guiding principles for AI implementation broadly, but there remains much scope to explore how these principles can be enacted in specific contexts-of-use. By drawing on ethical AI and task-technology fit literature, this paper constructs a decision-making framework to support the ethical deployment of AI for HRM and guide determinations of the optimal mix of human and machine involvement for different HRM tasks. Doing so supports the deployment of AI for the betterment of work and workers and generates both scholarly and practical outcomes. (shrink)

Dance as a complex human activity is a rich test case for exploring perception in action. In this article, we explore a 4E approach to perception/action in dance, focussing on the intersubjective and ecological aspects of kinaesthetic attunement and their capacity to expand empathic and perceptive experience. We examine the question: what are the ways in which the performance ecology co-created in different dance practices influences empathic and perceptive experience? We adopt an enactive ethnographic and phenomenological approach to explore two (...) distinct dance forms: Contact Improvisation [CI], a duet-system based practice aimed at fostering interkinaesthetic awareness and challenging habits of movement; and Body Weather [BW], an anti-hierarchical movement practice sensitive to the surrounding environment. We argue that through intersubjective kinaesthetic attunement, CI scaffolds the development of perceptive awareness of subtle shifts within ourselves and others, allowing the cultivation of a capacity for flexibly traversing between conscious initiation of action, attuned responding, and the intersection between them. Similarly, we investigate the expansion of perceptive experience through kinaesthetic attunement in BW. We suggest that the capacity for empathy is enhanced in BW through drawing attention to, and perception of, the fullness of a place in a way that we do not typically experience. By focussing on the variations in which embodied perceptual skills are enacted in specific dance forms and the expansion of perceptive experience through kinaesthetic attunement, we stress the potential of the performing arts to cultivate and create new ways of empathic engagement with the world in which we find ourselves.

Corporate sustainability introduces multiple tensions or paradoxes into organisations which defy traditional approaches such as trading-off contrasting options. We examine an alternative approach: to manage corporate sustainability with a paradoxical lens where contradictory elements are managed concurrently. Drawing on paradox theory, we focus on two specific pathways: to the organisation-wide acceptance of paradox and to paradoxical resolution. Introducing the concept of strategic agility, we argue that strategically agile organisations are better placed to navigate these paradox pathways. Strategic agility comprises three (...) organisational meta-capabilities: strategic sensitivity, collective commitment, and resource fluidity. We propose that strategically agile organisations draw on strategic sensitivity and collective commitment to achieve organisation-wide acceptance of paradox, and collective commitment and resource fluidity to achieve paradoxical resolution. For each of these meta-capabilities, we identify three organisational practices and processes specifically related to corporate sustainability that organisations can leverage in pursuit of strategic agility. We offer a conceptual framework depicting the strategic agility meta-capabilities, and associated practices and processes, which organisations draw on to successfully manage corporate sustainability with a paradoxical lens.
