ABSTRACTIs offering hazard pay ethically permissible when the pay premium is the only reason that a dangerous job is accepted? Robert C. Hughes argues that it is not. Central to his argument is the claim that in such cases, workers intend the foreseeable risks of harm as a means to the pay premium. Herein I question the plausibility of this claim and then develop a conception of the concept of means sufficient to make it plausible. By so doing, I provide (...) support for Hughes’s stringent position. (shrink)

This article argues that in Beyond Good and Evil (BGE) Nietzsche defends “will to power” as a transcendentally ideal condition of objectivity, in the sense in which Kant considers, say, space, time, or the concepts of substance and causation to be such conditions. The article shows how Nietzsche’s engage-ment with the transcendental idealist arguments of his Kantian contemporaries leads him to reject naturalism and to adopt a peculiarly transcendental kind of skepticism, which rejects as unjustified the conditions that would make (...) objec-tivity possible. The article then turns to the argument for “will to power” in BGE 36, showing that it is best read as defending a transcendentally ideal condition of objectivity, and thus as responding to transcendental skepticism. The article concludes by elaborating on this understanding of “will to power,” particularly in relation to the sense of causality that Nietzsche invokes and in comparison with Kant’s own transcendental claims.

_Utilitarianism_ is a classic work of ethical theory, arguably the most persuasive and comprehensible presentation of this widely influential position. Mill argues that it is pleasure and pain that ought to guide our decision-making&and not the pleasure and pain of any one person or group, but the summative experience of all who are affected by our actions. While he didn’t invent utilitarianism, Mill offered its clearest expression and strongest defense, and expanded the theory to account for the variety in quality (...) that we find among specific pleasures and pains. Today, Mill’s version of the “Greatest Happiness Principle” is a standard premise in many moral arguments within the academy and in practical ethical and political deliberation. The complete text of the 1871 edition of _Utilitarianism_ is presented here, with footnote annotations added to clarify unfamiliar references and terminology for the student reader. A detailed introduction by the editor is divided into brief digestible parts discussing the context of the text and offering guidelines on how to read it accurately and critically. This edition has its origin in the acclaimed _Broadview Anthology of Social and Political Thought_ and adheres to the anthology’s format and high standard of accuracy and accessibility. (shrink)

Among your closest associates is a certain human animal – a living, breathing, organism. You see it when you look in the mirror. When it is sick, you don't feel too well. Where it goes, you go. And, one thinks, where you go, it must follow. Indeed, you can make it move through sheer force of will. You bear, in short, an important and intimate relation to this, your animal. So too rest of us with our animals. Animalism says that (...) this relation is nothing short of identity. According to animalists, we do not only coincide with or constitute or inhabit or otherwise hang out with these close associates, our animals: we are them. In this article, I offer an opinionated take on what animalism might be and situate it against contemporary rivals. Then, I outline a simple case for animalism. Finally, I sketch non-standard routes for animalists to take in light of standard challenges. My goal in all of this is to open up some new avenues of animalist thinking. (shrink)

Here is a question as intriguing as it is brief: what are we? The animalist’s answer is equal in brevity: we are animals. This stark formulation of the animalist slogan distances it from nearby claims—that we are essentially animals, for example, or that we have purely biological criteria of identity over time. Is the animalist slogan—unburdened by modal or criterial commitments—still interesting, though? Or has it lost its bite? In this article we address such questions by presenting a positive case (...) for the importance of animalism and applying that case to recent critiques. (shrink)

Animalism is at once a bold metaphysical theory and a pedestrian biological observation. For according to animalists, human persons are organisms; we are members of a certain biological species. In this article, I introduce some heretofore unnoticed data concerning the interlocking interests of human persons and human organisms. I then show that the data support animalism. The result is a novel and powerful argument for animalism. Bold or pedestrian, animalism is true.

In this paper I address a tension in Samantha Vice’s claim that humility and silence offer effective moral responses to white shame in the wake of South African apartheid. Vice describes these twin virtues using inward-turning language of moral self-repair, but she also acknowledges that this ‘personal, inward directed project’ has relational dimensions. Her failure to explore the relational strand, however, leaves her description of white shame sounding solitary and penitent. -/- My response develops the missing relational dimensions of white (...) shame and humility arguing that this strand, once visible, complicates Vice’s project by (1) challenging her unitary and homogenous view of white identity, and (2) demonstrating the important role vulnerability plays in our understandings of white shame.

The Theaetetus’s midwife metaphor contains a puzzling feature, often referred to as the “midwife paradox”: the physical midwives must have first given birth to their own children in order to have the necessary experience to practice their art. Socrates, however, seems to disavow having any children of his own and thus appears to be unqualified to practice philosophical midwifery. In this paper, I aim to dissolve the midwife paradox by arguing that it rests on problematic assumptions, namely, that Socrates never (...) gave birth to a child at all or the child of wisdom in particular, and that he is primarily an intellectual midwife. I offer a new interpretation of Socratic midwifery, arguing that what Socrates may have birthed in the past which qualifies him for midwifery is his virtuous recognition of his ignorance, and that this “epistemic virtue” is also the proximate goal of Socratic midwifery.

A sensibility is, on a rough first pass, an emotional orientation to the world. It shapes how things appear to us, evaluatively speaking. By transfiguring things’ evaluative appearances, a change in sensibility can profoundly alter one’s overall experience of the world. I argue that some forms of sensibility change entail (1) risking one’s knowledge of what experiences imbued with one’s prior sensibility were like, and (2) surrendering one’s grasp on the intelligibility of one’s prior emotional apprehensions. These costs have consequences (...) for Laurie Paul’s ‘problem of transformative experience.’ Paul has argued that when we are poised to become someone new, our inexperience generates problems for authentic choice about our own futures. By reckoning with the epistemic losses involved in sensibility change, I show that this problem must not be confined to novel transformations. Prior experience does not guarantee the knowledge or understanding necessary for choosing authentically (in Paul’s sense). If the problem Paul highlights is indeed a problem _at all,_ then, it is a still more pervasive and intractable one than it has been taken to be. (shrink)

This paper deals with the relationship between the embodied cognition paradigm and two sets of its implications: its implications for the ontology of selves, and its implications for the nature and extent of phenomenal consciousness. There has been a recent wave of interest within cognitive science in the paradigm variously called ‘embodied,’ ‘extended,’ ‘situated’ or ‘distributed’ cognition. Although ideas applied in the embodied cognition research program can be traced back to the work of Heidegger, Piaget, Vygotsky, Merleau-Ponty, and Dewey, the (...) current thesis can be seen as a direct response and, in some cases, a proposed alternative to the cognitivist/classicist rule-based, information-processing model of cognition. Embodied cognition, by contrast, arises from real-time, goal-oriented bodily interactions with the world. I lay out three relations: the implications of embodiment for consciousness; the implications of embodiment for the self; and the tension between these two. I argue that the embodiment paradigm introduces a radical split between consciousness and the self, and that it does so by deflating our pre-theoretical instincts about consciousness and self in two different directions; however, I claim, what both these theoretical movements have in common is a scepticism about the notion of a psychological container defining a boundary between ‘inside’ and ‘outside.’ (203 words).

This practical textbook will enable students training to become registered behavior technicians (RBTs) to fully understand and follow the new RBT Ethics Code administered by the Behavior Analyst Certification Board (BACB). Starting with an overview of the role of ethics and core ethical principles, subsequent chapters provide concrete guidance for each of the three sections of the RBT Ethics Code: responsible conduct, responsibility to clients, and competence and service delivery. The authors then show correct and incorrect applications of each code (...) item and provide practical examples and solutions for applying each section to everyday practice. Also included are test questions where RBTs can test themselves on their newfound knowledge along with a glossary, the complete RBT Code of Ethics, and suggested readings. This book is intended to serve as a primary text for the training of Registered Behavior Technicians (RBTs) as well as a reference and study guide for these RBTs as well as their trainers. (shrink)

Background People who are at elevated risk of suicide stand to benefit from internet-based interventions; however, research in this area is likely impacted by a range of ethical and practical challenges. The aim of this study was to examine the ethical issues and practical barriers associated with clinical studies of internet-based interventions for suicide prevention. Method This was a mixed-methods study involving two phases. First, a systematic search was conducted to identify studies evaluating internet-based interventions for people at risk of (...) suicide, and information pertaining to safety protocols and exclusion criteria was extracted. Second, investigators on the included studies were invited to complete an online survey comprising open-ended and forced-choice responses. Quantitative and qualitative methods were used to analyse the data. Results The literature search identified 18 eligible studies, of which three excluded participants based on severity of suicide risk. Half of the 15 suicide researchers who participated in the survey had experienced problems obtaining ethics approval, and none had encountered adverse events attributed to their intervention. Survey respondents noted the difficulty of managing risk in online environments and the limitations associated with implementing safety protocols, although some also reported increased confidence resulting from the ethical review process. Respondents recommended researchers pursue a collaborative relationship with their research ethics committees. Conclusion There is a balance to be achieved between the need to minimise the risk of adverse events whilst also ensuring interventions are being validated on populations who may be most likely to use and benefit from them. Further research is required to obtain the views of research ethics committees and research participants on these issues. Dialogue between researchers and ethics committees is necessary to address the need to ensure safety while also advancing the timely development of effective interventions in this critical area.

There is a new objection to the Consequence Argument for incompatibilism. I argue that the objection is more wide-ranging than originally thought. In particular: if it tells against the Consequence Argument, it tells against other arguments for incompatibilism too. I survey a few ways of dealing with this objection and show the costs of each. I then present an argument for incompatibilism that is immune to the objection and that enjoys other advantages.

Empathy is a form of emotionally charged imaginative perspective‐taking. It is also the unique source of a particular form of understanding, which I will call humane understanding. Humane understanding consists in the direct apprehension of the intelligibility of others’ emotions. This apprehension is an epistemic good whose ethical significance is multifarious. In this paper, I focus on elaborating the sense in which humane understanding of others is non‐instrumentally valuable to its recipients. People have a complex but profound need to be (...) humanely understood. Because we respond to others’ very real need when we pursue this sort of understanding of their emotions, empathy is best understood as itself a way of caring, rather than just a means to promote other caring behavior.

Some strange cases have gripped philosophers of mind. They have been deployed against materialism about human persons, functionalism about mentality, the possibility of artificial intelligence, and more. In this paper, I cry “foul”. It’s not hard to think that there’s something wrong with the cases. But what? My proposal: their proponents ignore questions about composition. And ignoring composition is a mistake. Indeed, materialists about human persons, functionalists about mentality, and believers in the possibility of artificial intelligence can plausibly deploy moderate (...) theories of composition in defense of their views. And as it turns out, these strange cases are an interesting source of evidence for moderate theories of composition. (shrink)

Many have thought that there is a problem with causal commerce between immaterial souls and material bodies. In Physicalism or Something Near Enough, Jaegwon Kim attempts to spell out that problem. Rather than merely posing a question or raising a mystery for defenders of substance dualism to answer or address, he offers a compelling argument for the conclusion that immaterial souls cannot causally interact with material bodies. We offer a reconstruction of that argument that hinges on two premises: Kim’s Dictum (...) and the Nowhere Man principle. Kim’s Dictum says that causation requires a spatial relation. Nowhere Man says that souls can’t be in space. By our lights, both premises can be called into question. We’ll begin our evaluation of the argument by pointing out some consequences of Kim’s Dictum. For some, these will be costs. We will then present two defeaters for Kim’s Dictum and a critical analysis of Kim’s case for Nowhere Man. The upshot is that Kim’s argument against substance dualism fails. (shrink)

Are extremists (incels, neo-nazis, and the like) characteristically answerable for their moral and political convictions? Is it necessary to offer them reasoned arguments against their views, or is it instead appropriate to bypass that kind of engagement? Discussion of these questions has centered around the putative epistemic autonomy of extremists. The parties to this discussion have assumed that epistemic autonomy is solely (or at least primarily) a matter of epistemic independence, of believing based on epistemic reasons one has assessed for (...) oneself. Here, though, I make the case for shifting the terms of the debate. Epistemic independence is not sufficient to make one answerable for one’s beliefs. Epistemic autonomy, in the sense that matters for answerability, is also a matter of what I call epistemic receptivity. Extremists may be fiercely epistemic independent, but that commitment is characteristically paired with severe deficiencies in empathic orientation. Severe deficiencies in empathic orientation undermine extremists’ ability to adequately engage with competing evaluative perspectives, and thus compromise extremists’ epistemic autonomy. I consider how this conclusion should inform our thinking about what we owe to extremists. (shrink)

I introduce and argue for a Priority Principle, according to which we exemplify certain of our mental properties in the primary or non-derivative sense. I then apply this principle to several debates in the metaphysics and philosophy of mind.

In this volume, authors Alan Bailey and Dan O'Brien examine the full import of David Hume's arguments and the context of the society in which his work came to fruition. They analyze the nuanced nature of Hume's philosophical discourse and provide an informed look into his position on the possible content and rational justification of religious belief. The authors first detail the pressures and forms of repression that confronted any 18th century thinker wishing to challenge publicly the truth of (...) Christian theism. From there, they offer an overview of Hume's writings on religion, paying particular attention to the inter-relationships between the various works. They show that Hume's writings on religion are best seen as an artfully constructed web of irreligious argument that seeks to push forward a radical outlook, one that only emerges when the attention shifts from the individual sections of the web to its overall structure and context. Even though there is no explicit denial in any of Hume's published writings or private correspondence of the existence of God, the implications of his arguments often seem to point strongly towards atheism. David Hume was one of the leading British critics of Christianity and all forms of religion at a time when public utterances or published writings denying the truth of Christianity were liable to legal prosecution. His philosophical and historical writings offer a sustained and remarkably open critique of religion that is unmatched by any previous author writing in English. Yet, despite Hume's widespread reputation amongst his contemporaries for extreme irreligion, the subtle and measured manner in which he presents his position means that it remains far from clear how radical his views actually were.

Paper presented at the Heidegger Circle 2011. Although Aristotle’s influence on young Heidegger’s thought has been studied at length, such studies have almost exclusively focused on his interpretation of Aristotle’s ethics, physics and metaphysics. I will rather address Heidegger’s appropriation of Aristotle’s ontology of life. Focusing on recently published or recently translated courses of the mid 20’s (mainly SS 1924, WS 1925-26 and SS 1926), I hope to uncover an important aspect of young Heidegger’s thought left unconsidered: namely, that Dasein’s (...) existential structures – Befindlichkeit, Understanding and being-with-one-another through language – arose from his close reading of Aristotle’s ontology of life, of animal life.

This book offers ways to overcome problems that arise when voters, politicians, and bureaucrats pursue selfish interests rather than the general interest in their political behavior. It combines previously published ideas about charging people the costs of their political actions and selling insurance against unfavorable political outcomes, with new ideas about competing legislatures and incentives for generating efficient political outcomes. The book includes new are discussed, as well as a proposed constitution and its rationale.

In its recent history, the philosophy of mind has come to resemble an entry into the genre of Hammer horror or pulpy science fiction. These days it is unusual to encounter a major philosophical work on the mind that is not populated with bats, homunculi, swamp-creatures, cruelly imprisoned genius scientists, aliens, cyborgs, other-worldly twins, self-aware Computer programs, Frankenstein-monster-like ‘Blockheads,’ or zombies. The purpose of this paper is to review the role in the philosophy of mind of one of these fantastic (...) thought-experiments — the zombie — and to reassess the implications of zombie arguments, which I will suggest have been widely misinterpreted. I shall argue that zombies, far from being the enemy of materialism, are its friend; and furthermore that zombies militate against the computational model of consciousness and in favour of more biologically-rooted conceptions, and hence that zombie- considerations support a morereductivekind of physicalism about consciousness than has been in vogue in recent years.

Our collective enthusiasm for empathy reflects a sense that it is deeply valuable. I show that empathy bears a complex and surprisingly problematic relation to another social epistemic phenomenon that we have reason to value, namely testimonial trust. My discussion focuses on empathy with and trust in people who are members of one or more oppressed groups. Empathy for oppressed people can be a powerful tool for engendering a certain form of testimonial trust, because there is a tight connection between (...) empathy and a approval of another's outlook. I then argue that the qualities of empathy that make it such a powerful tool for bridging differences and building trust also have a problematic upshot: they make it the case that reliance on empathy will sometimes have a distorting effect upon the ways we extend testimonial trust.

One of the aspects of consciousness deserving of study is what might be called its subjective unity - the way in which, though conscious experience moves from object to object, and can be said to have distinct ‘states', it nevertheless in some sense apparently forms a singular flux divided only by periods of unconsciousness. The work of William James provides a valuable, and rather unique, source of analysis of this feature of consciousness; however, in my opinion, this component of James’ (...) theory of the mind has so far gone under-emphasized in the scholarly literature. This paper undertakes some philosophical geography, trying to draw out and elucidate some of the relevant ideas from James’ corpus, and also subjects those ideas to some analysis to try and assist in judgements of their current importance.

Here's an interesting question: what are we? David Barnett has claimed that reflection on consciousness suggests an answer: we are simple. Barnett argues that the mereological simplicity of conscious beings best explains the Datum: that no pair of persons can itself be conscious. In this paper, I offer two alternative explanations of the Datum. If either is correct, Barnett's argument fails. First, there aren't any such things as pairs of persons. Second, consciousness is maximal; no conscious thing is a proper (...) part of another conscious thing. I conclude by showing how both moves comport with materialist theories of what we are and then apply them to another anti-materialist argument. (shrink)

This title was first published in 2000. Drawing on exclusive interviews with Karl Popper, this book provides the first comprehensive examination of the educational implications of his philosophy. Critically exploring key elements of Popper's work, his theory of knowledge, psychology of learning and politics, Richard Bailey also extrapolates an approach to teaching and learning in schools and the wider community.

There are predicates and subjects. It is thus tempting to think that there are properties on the one hand, and things that have them on the other. I have no quarrel with this thought; it is a fine place to begin a theory of properties and property-having. But in this paper, I argue that one such theory—bare particularism—is false. I pose a dilemma. Either bare particulars instantiate the properties of their host substances or they do not. If they do not, (...) then bare particularism is both unmotivated and false. If they do, then the view faces a problematic—and, I shall argue, false—crowding consequence. (shrink)

Grounded in what Alan Wertheimer terms the nonworseness claim, it is thought by some philosophers that what will be referred to herein as better-than-permissible acts —acts that, if undertaken, would make another or others better off than they would be were an alternative but morally permissible act to be undertaken—are necessarily morally permissible. What, other than a bout of irrationality, it may be thought, would lead one to hold that an act (such as outsourcing production to a sweatshop in a (...) developing country) that produces more benefits for others than an act that is itself morally permissible (such as not doing business in the developing country at all) with respect to those same others, is not morally permissible? In this article, I argue that each of the two groups of philosophers that are most likely to accept the nonworseness claim—consequentialists and non-consequentialists—have reason to reject it, and thereby also have reason to reject the belief that better-than-permissible acts are necessarily morally permissible.

Aristotle famously held that objects are comprised of matter and form. That is the central doctrine of hylomorphism (sometimes rendered “hylemorphism”—hyle, matter; morphe, form), and the view has become a live topic of inquiry today. Contemporary proponents of the doctrine include Jeffrey Brower, Kit Fine, David Hershenov, Mark Johnston, Kathrin Koslicki, Anna Marmodoro, Michael Rea, and Patrick Toner, among others. In the wake of these contemporary hylomorphic theories the doctrine has seen application to various topics within mainstream analytic metaphysics. Here, (...) appeals to form and matter are used to shed light on problems about ontology, personal identity, philosophy of mind, and philosophy of religion. The current entry documents this resurgence of interest in hylomorphism, the ways it has been applied, and its reception. (shrink)

Materialists about human persons think that we are material through and through—wholly material beings. Those who endorse materialism more widely think that everything is material through and through. But what is it to be wholly material? In this article, I answer that question. I identify and defend a definition or analysis of ‘wholly material’.

Alison Bailey’s The Weight of Whiteness: A Feminist Engagement with Privilege, Race, and Ignorance examines how whiteness misshapes our humanity, measuring the weight of whiteness in terms of its costs and losses to collective humanity. People of color feel the weight of whiteness daily. The resistant habits of whiteness and its attendant privileges, however, make it difficult for white people to feel the damage. White people are more comfortable thinking about white supremacy in terms of what privilege does for (...) them, rather than feeling what it does to them. The first half of the book focuses on the overexposed side of white privilege, the side that works to make the invisible and intangible structures of power more visible and tangible. Bailey discusses the importance of understanding privileges intersectionally, the ignorance-preserving habits of “white talk,” and how privilege and ignorance circulate in educational settings. The second part invites white readers to explore the underexposed side of white dominance, the weightless side that they would rather not feel. The final chapters are powerfully autobiographical. Bailey engages readers with a deeply personal account of what it means to hold space with the painful weight of whiteness in her own life. She also offers a moving account of medicinal genealogies, which helps to engage the weight she inherits from her settler colonial ancestors. The book illustrates how the gravitational pull of white ignorance and comfort are stronger than the clean pain required for collective liberation. The stakes are high: Failure to hold the weight of whiteness ensures that white people will continue to blow the weight of historical trauma through communities of color. -/- All rights reserved.

The Russian invasion of Ukraine in 2022 was met with condemnation from the European Union and the United States as an "unprovoked and unjustified military aggression" that undermines the liberal international order. However, some international relations scholars, such as John Mearsheimer, argue that Russia had genuine security concerns with regard to Ukraine and that the invasion was a response to the threat of NATO membership for Ukraine. Both liberal and realist perspectives on the invasion rely on the assumption of rational, (...) cost-benefit calculations by actors, but cultural factors and irreconcilable non-material interests may also be at play in shaping the actions and motivations of states. Understanding the cultural and national identity factors at play in the invasion of Ukraine is complex and difficult, but they cannot be ignored in attempting to understand and address the conflict.

Humans are an exceptionally cooperative species, but there is substantial variation in the extent of cooperation across societies. Understanding the sources of this variability may provide insights about the forces that sustain cooperation. We examined the ontogeny of prosocial behavior by studying 326 children 3–14 y of age and 120 adults from six societies (age distributions varied across societies). These six societies span a wide range of extant human variation in culture, geography, and subsistence strategies, including foragers, herders, horticulturalists, and (...) urban dwellers across the Americas, Oceania, and Africa. When delivering benefits to others was personally costly, rates of prosocial behavior dropped across all six societies as children approached middle childhood and then rates of prosociality diverged as children tracked toward the behavior of adults in their own societies. When prosocial acts did not require personal sacrifice, prosocial responses increased steadily as children matured with little variation in behavior across societies. Our results are consistent with theories emphasizing the importance of acquired cultural norms in shaping costly forms of cooperation and creating cross-cultural diversity. (shrink)
