Nurses practising in mental health are faced with challenging decisions concerning confidentiality if a patient is deemed a potential risk to self or others, because releasing pertinent information pertaining to the patient may be necessary to circumvent harm. However, decisions to withhold or disclose confidential information that are inappropriately made may lead to adverse outcomes for stakeholders, including nurses and their patients. Nonetheless, there is a dearth of contemporary research literature to advise nurses in these circumstances. Cognitive Continuum Theory presents (...) a single‐system intuitive‐analytical approach to examining and understanding nurse cognition, analogous to the recommended single‐system approach to decision‐making in mental health known as structured clinical judgement. Both approaches incorporate cognitive poles of wholly intuition and analysis and a dynamic continuum characterised by a ‘common sense’ blending of intuitive and analytical cognition, whereby cues presented to a decision‐maker for judgement tasks are weighed and assessed for relevance. Furthermore, Cognitive Continuum Theory promotes the importance of determining pattern recognition and functional relations strategies, which can be used to understand the operationalisation of nurse cognition.

Incomplete information is a commonly cited barrier to the adoption of new innovations. We present a decision-making experiment, conducted with farmers in the field, that explores the extent to which information which reduces ambiguity may be provided as a public good. In the experiment, participants make a series of decisions between a risky gamble and an ambiguous gamble. An initial private decision is followed by second choice in which participants know that their chosen gambles and outcomes will be publicly but (...) anonymously revealed. Selection of the ambiguous option in this decision thus provide public good information which can be used to update beliefs about the ambiguous gamble. After the public revelation, participants make one final choice between the two options which we use to assess learning. We also test communication as a mechanism to increase provision of the public good. We find evidence that people with preference to avoid ambiguity contribute to public good information while risk averse people free ride. Communication does not affect the overall public good provision, either in a positive or negative direction. Finally, we find that people draw appropriate inference from the information that the public good provides. We relate our findings to the issue of new technology adoption in agriculture which is of particular importance for our participants. (shrink)

Humanity stands at a precipice. -/- Our species could survive for millions of generations — enough time to end disease, poverty, and injustice; to reach new heights of flourishing. But this vast future is at risk. With the advent of nuclear weapons, humanity entered a new age, gaining the power to destroy ourselves, without the wisdom to ensure we won’t. Since then, these dangers have only multiplied, from climate change to engineered pandemics and unaligned artificial intelligence. If we do not (...) act fast to reach a place of safety, it may soon be too late. -/- The Precipice explores the science behind the risks we face. It puts them in the context of the greater story of humanity: showing how ending these risks is among the most pressing moral issues of our time. And it points the way forward, to the actions and strategies we can take today to safeguard humanity’s future. (shrink)

Prioritarianism is the moral view that a fixed improvement in someone's well-being matters more the worse off they are. Its supporters argue that it best captures our intuitions about unequal distributions of well-being. I show that prioritarianism sometimes recommends acts that will make things more unequal while simultaneously lowering the total well-being and making things worse for everyone ex ante. Intuitively, there is little to recommend such acts and I take this to be a serious counterexample for prioritarianism.

Nietzsche offers us an account of how different drives interact with one another; it is rich but also appears to risk the homunculus fallacy. Competing attempts to deflect this charge on his behalf share an implicit consensus about the ‘epistemic ends’ of the account: they assume Nietzsche is trying to provide true explanations of psychological phenomena. I argue against this consensus. I claim that Nietzsche's characterisations of drive interaction are to be taken as fictive and are not intended to have (...) explanatory value. They nevertheless facilitate genuine epistemic achievement. Drawing on Catherine Elgin's account of the epistemic role of idealised models in science, I argue that Nietzsche's account of drive interaction is a ‘model of the mind’ that, despite relying on falsehoods, can exemplify features of our psychology that aid us in making novel predictions. We then see that Nietzsche neatly sidesteps the homunculus fallacy; we can further understand more fully what Nietzsche hopes his drive psychology will teach us. We can now resolve, for example, outstanding interpretative puzzles about the relationship between psychic integration and Nietzsche’s distinctive notion of spiritual health. (shrink)

We think we know what healers do: they build on patients' irrational beliefs and treat them in a 'symbolic' way. If they get results, it's thanks to their capacity to listen, rather than any influence on a clinical level. At the same time, we also think we know what modern medicine is: a highly technical and rational process, but one that scarcely listens to patients at all. In this book, ethnopsychiatrist Tobie Nathan and philosopher Isabelle Stengers argue that this commonly (...) posed opposition between traditional and modern medicine is misleading. They show instead that healers are interesting precisely because they don't listen to patients, using techniques of 'divination' rather than 'diagnosis'. Healers construct genuine therapeutic strategies by identifying the origins of symptoms in external forces, outside of the mind of the sufferer, and in this regard African healers are virtuosos. Though it may claim otherwise, modern medicine, for its part, is characterised by empiricism rather than rationality. What appears to be the pursuit of rationality is ultimately only a means to dismiss and exclude other forms of treatment. Blurring the distinctions between traditional and modern practices and drawing on perspectives from across the globe, this ethnopsychiatric manifesto encourages us to think in radically new ways about illness, challenging accepted notions on the relationship between sufferer and symptom. It will be of great interest to those working in medicine and healthcare, as well as anthropologists, social scientists and those in the humanities more broadly. (shrink)

The emerging field of comparative political theory (CPT) seeks to expand our understanding of politics through intercultural dialogues between diverse systems of political thought. CPT acknowledges diverse modes of political understanding, yet the field is still methodologically focused on textual forms of political practice and learning. I argue that the privileging of political literature in CPT has been inherited from orthodox political theory and the history of political thought and that the prioritizing of text over oral and enactive practices places (...) constraints on intercultural dialogue. First, methodological focus on texts inhibits dialogue with Indigenous traditions that do not prioritize text in the same way or to the same extent in the reproduction of political culture. Second, the incorporation of oral traditions tends to conflate orality with text in ways that obfuscate the contribution of enactive performance. One result of these methodological oversights is that CPT risks recapitulating some of the historical exclusionary logics that it seeks to overcome. (shrink)

“I suppose I still hold on to a shred of hope that being independent-minded and having the intellectual equipment to analyse ideas properly will lead to better practice. But ultimately, it must just be that being able to see the world clearly and knowing how to go about discovering the truth about ideas is reward enough in itself.”.

Drawing on theoretical arguments from the psychology discipline, we investigate the implications of employee entitlement in organizational settings. Specifically, we utilize workplace engagement theory to suggest that due to their skewed sense of deservingness, employees high in entitlement are less likely to experience workplace engagement. Furthermore, the negative relationship between employee entitlement and workplace engagement is strengthened when ethical leadership is low, yet mitigated when ethical leadership is high. Finally, we predict that under conditions of low ethical leadership, reductions in (...) engagement explain why employee entitlement results in hindered job performance. This mediated effect does not hold when ethical leadership is high. We tested our theoretical model utilizing field data from employees and their direct supervisors in the financial services industry. Our results support our theoretical model. Theoretical and practical implications are discussed. (shrink)

It has often been noted that there is some tension between engaging in decision-making and believing that one’s choices might be predetermined. The possibility that our choices are predetermined forces us to consider, in our decisions, act-state pairs which are inconsistent, and hence to which we cannot assign sensible utilities. But the reasoning which justifies two-boxing in Newcomb’s problem also justifies associating a non-zero causal probability with these inconsistent act-state pairs. Put together these undefined utilities and non-zero probabilities entail that (...) expected utilities are undefined whenever it is a possibility that our choices are predetermined. There are three ways to solve the problem, but all of them suffer serious costs: always assume that, contrary to our evidence, the outcome of our present decision-making is not predetermined; give up the reasoning that justifies unconditional two-boxing in Newcomb’s problem; or allow epistemically impossible outcomes to contribute to expected utility, leading to the wrong results in a series of cases introduced by Ahmed :665–685, 2014a, Evidence, decision and causality, Cambridge University Press, Cambridge, 2014b). However they choose to respond, causal decision theorists cannot remain silent: the intuitive tension between decision-making and the possibility of predetermination can be made precise, and resolving it will require giving up something. Causal decision theorists have a predetermination problem. (shrink)

Settler colonialism is structured in part according to the principle of civilizational progress yet the roots of this doctrine are not well understood. Disparate ideas of progress and practices related to colonial dispossession and domination can be traced back to the Enlightenment, and as far back as ancient Greece, but there remain unexplored logics and continuities. I argue that civilizational progress and settler colonialism are structured according to the opposition between politics governed by reason or faith and the figure of (...) the child as sinful or bestial. Thus, it is not contingent, but rather necessary that justificatory frameworks of European empire and colonialism depict Indigenous peoples as children. To illustrate how the theoretical link between Indigenous peoples and children emerges not as a simple analogy, but rather, as the source of the premodern/modern and savage/civilized binaries, I trace the various historical iterations of the political/childhood opposition through the classical, medieval, enlightenment, and modern eras. I show how the model of civilizational progress from a premodern and savage state of childhood continues to serve as the model for settler colonial exclusion and domination of Indigenous peoples.

It is a commonplace that scientific inquiry makes extensive use of probabilities, many of which seem to be objective chances, describing features of reality that are independent of our minds. Such chances appear to have a number of paradoxical or puzzling features: they appear to be mind-independent facts, but they are intimately connected with rational psychology; they display a temporal asymmetry, but they are supposed to be grounded in physical laws that are time-symmetric; and chances are used to explain and (...) predict frequencies of events, although they cannot be reduced to those frequencies. This book offers an accessible and non-technical introduction to these and other puzzles. Toby Handfield engages with traditional metaphysics and philosophy of science, drawing upon recent work in the foundations of quantum mechanics and thermodynamics to provide a novel account of objective probability that is empirically informed without requiring specialist scientific knowledge.

When an agent suffers in their capacity as a knower, they are a victim of epistemic injustice. Varieties of epistemic injustices have been theorised. A salient feature across these theories is that perpetrators and victims of epistemic injustice belong to different social groups. In this paper, I argue for a form of epistemic injustice that could occur between members of the same social group. This is a form of epistemic injustice where the knower is first a victim of historical and (...) continuing oppression. Secondly, they internalise and appreciate the systems that harm them as a knower. This is possible because the victim subscribes to perniciously formed epistemic systems. This form of epistemic injustice is a valuable explanatory tool for non-standard and obscure instances of epistemic injustice where the victim a) accepts and appreciates the injustice they experience and b) is even the seeming perpetrator of the injustice against themselves.

In J Philos Logic 34:155–192, 2005, Leitgeb provides a theory of truth which is based on a theory of semantic dependence. We argue here that the conceptual thrust of this approach provides us with the best way of dealing with semantic paradoxes in a manner that is acceptable to a classical logician. However, in investigating a problem that was raised at the end of J Philos Logic 34:155–192, 2005, we discover that something is missing from Leitgeb’s original definition. Moreover, we (...) show that once the appropriate repairs have been made, the resultant definition is equivalent to a version of the supervaluation definition suggested in J Philos 72:690–716, 1975 and discussed in detail in J Symb Log 51(3):663–681, 1986. The upshot of this is a philosophical justification for the simple supervaluation approach and fresh insight into its workings. (shrink)

The deliberative systems approach is a recent innovation within the tradition of deliberative democratic theory. It signals an important shift in focus from the political legitimacy produced within isolated and formal sites of deliberation (e.g., Parliament or deliberative mini-publics), to the legitimacy produced by a number of diverse interconnected sites. In this respect, the deliberative systems (DS) approach is better equipped to identify and address defects arising from the systemic influences of power and coercion. In this article, I examine one (...) of the least explored and least understood defects: the exclusion of non-speaking political actors generated by the uniform privileging of speech in all sites within a system. Using the examples of prefigurative protest, Indigenous refusal to deliberate, and the non-deliberative agency of disabled citizens, I argue that the DS approach allows theorists to better understand forms of domination related to the imposition of speech on those who are either unwilling or unable to speak.

Virtue words, such as justice, fairness, care, and integrity, frequently feature in organizational codes of conduct and theories of ethical leadership. And yet our modern organizations remain blemished by examples lacking virtue. The philosophy of virtue ethics and numerous extant theories of leadership cite virtues as essential to good leadership. But we seem to lack understanding of how to develop or embed these virtues and notions of good leadership in practice. In 2012, virtue ethicist Julia Annas pointed to a training (...) program which she touted as a practical application of virtue ethics. The program Annas identified is called The Virtues Project, and while promising, she warned that in its current state, it lacked theorizing. We address this by aligning its practical strategies to extant theory and evidence to understand what virtues it might develop and how it might facilitate good leadership. Doing so makes two key contributions. First, it lends credence to The Virtues Project’s potential as a leadership development program. Second, it provides a means of applying theories of good leadership in practice. Our overarching objective is to advance The Virtues Project as a means of incorporating virtues into workplace dynamics and embedding virtues in the practice of organizational leadership. (shrink)

Instances of epistemic injustice elicit resistance, anger, despair, frustration or cognate emotional responses from their victims. This sort of response to the epistemic injustices that accompanied historical systems of oppression such as colonialism, for example, is normal. However, if their victims have internalised these oppressive situations, we could get the counterintuitive response of appreciation. In this paper, I argue for the phenomenon of appreciative silencing to make sense of instances like this. This is a form of epistemic silencing that happens (...) when the accepted hegemonic intuitions of the oppressed are formed/influenced by the ideologies of the oppressors over time. Here, we have a resilient, oppressive and hegemonic epistemic system. Put together, it creates a variant of epistemic injustice and silencing that is obscure since its victims are neither resistant nor aware of the injustice they face but are appreciative. (shrink)

In this book, Toby Svoboda develops and defends a Kantian environmental virtue ethic, challenging the widely-held view that Kant's moral philosophy takes an instrumental view toward nature and animals and has little to offer environmental ethics. On the contrary, Svoboda posits that there is good moral reason to care about non-human organisms in their own right and to value their flourishing independently of human interests, since doing so is constitutive of certain virtues. Svoboda argues that Kant’s account of indirect (...) duties regarding nature can ground a compelling environmental ethic: the Kantian duty to develop morally virtuous dispositions strictly proscribes unnecessarily harming organisms, and Svoboda argues that this duty compels us to act in ways that benefit non-human organisms, given that doing so can enhance one’s virtues. Svoboda’s argument engages the recent literature on environmental virtue and provides an original argument for an environmental virtue ethic firmly rooted in Kant’s moral philosophy. (shrink)

What sense, if any, does it make to speak of God? This question, of such vital importance to religious commitment, occupies an important place in discussion among Anglo-American philosophers of religion whose orientation is logical analysis. ‘Metatheological scepticism’ is the view that denies the intelligibility of religious discourse, derived from a theory of meaning which holds that a sentence has cognitive significance only if it makes a statement that is conclusively verifiable on empirical grounds. Dr Heimbeck’s argument for the cognitive (...) nature of religious discourse is twofold. First, he shows that such discourse can qualify as cognitively significant without having to satisfy the verification requirement. Secondly, he shows that it does in fact satisfy such a requirement because it is firmly rooted in the empirical realm. Originally published in 1969, this book, for teachers and students of philosophy of religion, is both easily comprehensible and highly readable, although the discussion of philosophical and theological points is conducted at an advanced level.

This paper argues that historians of ideas must, when seeking to reconstruct webs of beliefs, interpret texts as though they were performances. As this is particularly the case with dialogic texts, the paper focuses on Plato's dialogues to show that the arguments expressed therein cannot be taken as expressions of Plato's beliefs. Rather, such arguments seek to prompt thought in their readers and thus reveal beliefs indirectly. We must therefore revise Mark Bevir's account of the reconstruction of webs of beliefs (...) so that we construct a consistent web and then assume that to be the web of the author in question, rather than assuming that the web we construct is a consistent one. Consideration of Leo Strauss's argument that philosophers have often had to hide their meaning for fear of persecution, the paper concludes that its argument may apply to treatise-based writing as well as to dialogues. All texts include an element of the performative. (shrink)

This article considers the nature of communitarian thought in late twentieth century Anglo-American political philosophy. It argues that communitarianism arose out of a critique of modernist theories of justice such as that of John Rawls shared by a group of writers committed to idealist principles that emphasised narrative approaches to the study of political thought, the importance of historical context, and popular participation in political life. It then focuses on one particular American strand of communitarian thought, exemplified by the work (...) of Michael Walzer and Michael Sandel, which draws on a tradition of radical democracy and, in so doing, helps both to create and to transform a new American republicanism. An important connection between Walzer and Sandel is that they share the view that egalitarian politics must draw on shared traditions of social criticism rather than on the abstract individualism that they associate with Rawls. A key difference is that Walzer's vision of American life is pluralist and enthusiastic about difference, whereas Sandel's is republican and concerned above all with fostering civic virtue and identification with the state and political community.

In this article, I outline the major themes of ‘anti-theodicy’. Anti-theodicy is characterised as a reaction, as rejection, against traditional solutions to the problem of evil and against the traditional formulations of the problem of evil to which those solutions respond. I detail numerous ‘moral’ anti-theodical objections to theodicy, illustrating the central claim of anti-theodicy: Theodicy is morally objectionable. I also detail some ‘non-moral’ anti-theodical objections, illustrating the second major claim of anti-theodicy: Traditional formulations of the problem of evil are (...) conceptually misguided. My focus remains on the analytic philosophical tradition throughout, but I briefly allude to the rich theological tradition of anti-theodicy. Although we should recognise the significant degree of diversity amongst anti-theodical arguments and the philosophical views of their proponents, this article should serve to illustrate the general theme: ‘Theodicies mediate a praxis that sanctions evil.’.

Contentless experience involves an absence of mental content such as thought, perception, and mental imagery. In academic work it has been classically treated as including states like those aimed for in Shamatha, Transcendental, and Stillness Meditation. We have used evidence synthesis to select and review 135 expert texts from within the three traditions. In this paper we identify the features of contentless experience referred to in the expert texts and determine whether the experiences are the same or different across the (...) practices with respect to each feature. We identify 65 features reported or implied in one or more practices, with most being reported or implied in all three. While there are broad similarities in the experiences across the traditions, we find that there are differences with respect to four features and possibly many others. The main difference identified is that Shamatha involves substantially greater attentional stability and vividness. Another key finding is that numerous forms of content are present in the experiences, including wakefulness, naturalness, calm, bliss/joy, and freedom. The findings indicate that meditation experiences described as contentless in the academic literature can in fact involve considerable variation, and that in many and perhaps most cases these experiences are not truly contentless. This challenges classical understandings in academic research that in these so-called contentless experiences all content is absent, and that the experiences are therefore an identical state of _pure consciousness_ or consciousness itself. Our assessment is that it remains an open question whether the experiences aimed for in the three practices should be classed as pure consciousness. Implications of our analysis for neuroscientific and clinical studies and for basic understandings of the practices are discussed. (shrink)

Shamatha, Transcendental, and Stillness Meditation are said to aim for “contentless” experiences, where mental content such as thoughts, perceptions, and mental images is absent. Silence is understood to be a central feature of those experiences. The main source of information about the experiences is texts by experts from within the three traditions. Previous research has tended not to use an explicit scientific method for selecting and reviewing expert texts on meditation. We have identified evidence synthesis as a robust and transparent (...) method that is suitable for this purpose. In this paper we use evidence synthesis based on expert texts to examine silence/quietness as a feature of the contentless experiences in the three practices. Objective criteria were used to select a sample of 135 expert texts. A database containing the expert descriptions of the meditation techniques and experiences was produced by extracting the relevant material from the publications and coding that material to differentiate individual features. The database, which forms part of the supplementary material for this paper, identifies each feature of the contentless experiences referred to in the expert texts, including silence/quietness. Our key finding is that the experts indicate silence/quietness has a particular connection with stillness, and the absence of concepts, mental activity/noise, thoughts, and disturbance. Further analysis leads to the following insights. The silence/quietness reflects the absence of thoughts and sounds, and this fits neatly with a conception of silence/quietness as the absence of internal and external noise. In some cases the terms silence and quietness may also reflect the absence of other disturbances such as non-auditory perceptions, mental images, and negative feelings. That would fit with a conception of silence/quietness as complete calm or absence of disturbance. It is not clear from the expert texts how silence/quietness is distinct from other features such as stillness that also reflect the absence of disturbances. As a separate matter, silence/quietness has connections with all the other features of the contentless experiences, but the closeness of the connections varies. Our work uncovers fine distinctions and ambiguities which lead to new research questions that can be explored in future studies. (shrink)

Some authors have called for increased research on various forms of geoengineering as a means to address global climate change. This paper focuses on the question of whether a particular form of geoengineering, namely deploying sulfate aerosols in the stratosphere to counteract some of the effects of increased greenhouse gas concentrations, would be a just response to climate change. In particular, we examine problems sulfate aerosol geoengineering (SAG) faces in meeting the requirements of distributive, intergenerational, and procedural justice. We argue (...) that SAG faces obstacles to meeting the requirements of all three considered kinds of justice, because its impacts can harm some persons and communities much more than others; it poses serious risks to future generations; and SAG is especially prone to unilateral implementation. While we do not claim that SAG ought not to be implemented, we argue that it is the responsibility of proponents of SAG to recognize and address these ethical obstacles before advocating its implementation.

It is often claimed that from the moment of conception embryos have the same moral status as adult humans. This claim plays a central role in many arguments against abortion, in vitro fertilization, and stem cell research. In what follows, I show that this claim leads directly to an unexpected and unwelcome conclusion: that natural embryo loss is one of the greatest problems of our time and that we must do almost everything in our power to prevent it. I examine (...) the responses available to those who hold that embryos have full moral status and conclude that they cannot avoid the force of this argument without giving up this key claim.

If A is better than B and B is better than C, then A is better than C, right? Larry Temkin and Stuart Rachels say: No! Betterness is nontransitive, they claim. In this paper, I discuss the central type of argument advanced by Temkin and Rachels for this radical idea, and argue that, given this view very likely has sceptical implications for practical reason, we would do well to identify alternative responses. I propose one such response, which employs the idea (...) that rational agents might regard some options as incommensurate in value, and will reasonably employ a heuristic of status quo maintenance to avoid suboptimal choices from incommensurate goods.

The binary between the figure of the child and the fully human being is invoked with regularity in analyses of race, yet its centrality to the conception of race has never been fully explored. For most commentators, the figure of the child operates as a metaphoric or rhetorical trope, a non-essential strategic tool in the perpetuation of White supremacy. As I show in the following, the child/human binary does not present a contingent or merely rhetorical construction but, rather, a central (...) feature of racialization. Where Black peoples are situated as objects of violence it is often precisely because Blackness has been identified with childhood and childhood is historically identified as the archetypal site of naturalized violence and servitude. I proceed by offering a historical account of how Black peoples came to inherit the subordination and dehumanization of European childhood and how White youth were subsequently spared through their partial categorization as adults.

The paper questions the common assumption that rational individuals believe all propositions which they know to be logical consequences of their other beliefs: although we must acknowledge the truth of a proposition which is a deductive consequence of our beliefs, we may not genuinely believe it. This conclusion is defended by arguing that some familiar counterexamples to the claim that knowledge is justified true belief fail because they involve propositions which are not really believed. Beliefs guide conduct or issue in (...) assertion by answering questions which arise in the course of deliberation and conversation, but the troublesome cases present propositions which do not present the agent's answer to any question. The paper concludes by sketching the conditions under which the deductive consequences of our beliefs can be believed.1. (shrink)

Moral error theorists hold that morality is deeply mistaken, thus raising the question of whether and how moral judgments and utterances should continue to be employed. Proposals include simply abolishing morality, adopting some revisionary fictionalist stance toward morality, and conserving moral judgments and utterances unchanged. I defend a fourth proposal, namely revisionary moral expressivism, which recommends replacing cognitivist moral judgments and utterances with non-cognitivist ones. Given that non-cognitivist attitudes are not truth apt, revisionary expressivism does not involve moral error. Moreover, (...) revisionary expressivism has the theoretical resources to retain many of the useful features of morality, such as moral motivation, moral disagreement, and moral reasoning. Revisionary expressivism fares better than the three major alternatives in both avoiding moral error and preserving these useful features of morality. I also show how this position differs from the “revolutionary expressivism” of Sebastian Köhler and Michael Ridge. (shrink)

In providing a good foundation for mathematics, set theorists often aim to develop the strongest theories possible and avoid those theories that place undue restrictions on the capacity to possess strength. For example, adding a measurable cardinal to $ZFC$ is thought to give a stronger theory than adding $V=L$ and the latter is thought to be more restrictive than the former. The two main proponents of this style of account are Penelope Maddy and John Steel. In this paper, I’ll offer (...) a third account that is intended to provide a simple analysis of restrictiveness based on the algebraic concept of retraction in the category of theories. I will also deliver some results and arguments that suggest some plausible alternative approaches to analyzing restrictiveness do not live up to their intuitive motivation. (shrink)
