Buddhism originated and developed in an Indian cultural context that featured many first-person practices for producing and exploring states of consciousness through the systematic training of attention. In contrast, the dominant methods of investigating the mind in Western cognitive science have emphasized third-person observation of the brain and behavior. In this chapter, we explore how these two different projects might prove mutually beneficial. We lay the groundwork for a cross-cultural cognitive science by using one traditional Buddhist model of the mind (...) – that of the five aggregates – as a lens for examining contemporary cognitive science conceptions of consciousness.

This article provides a discussion of the principle of transmission of evidential support across entailment from the perspective of belief revision theory in the AGM tradition. After outlining and briefly defending a small number of basic principles of belief change, which include a number of belief contraction analogues of the Darwiche-Pearl postulates for iterated revision, a proposal is then made concerning the connection between evidential beliefs and belief change policies in rational agents. This proposal is found to be suffcient to (...) establish the truth of a much-discussed intuition regarding transmission failure. (shrink)

As the ongoing literature on the paradoxes of the Lottery and the Preface reminds us, the nature of the relation between probability and rational acceptability remains far from settled. This article provides a novel perspective on the matter by exploiting a recently noted structural parallel with the problem of judgment aggregation. After offering a number of general desiderata on the relation between finite probability models and sets of accepted sentences in a Boolean sentential language, it is noted that a number (...) of these constraints will be satisfied if and only if acceptable sentences are true under all valuations in a distinguished non-empty set W. Drawing inspiration from distance-based aggregation procedures, various scoring rule based membership conditions for W are discussed and a possible point of contact with ranking theory is considered. The paper closes with various suggestions for further research. (shrink)

It is well known that classical, aka ‘sharp’, Bayesian decision theory, which models belief states as single probability functions, faces a number of serious difficulties with respect to its handling of agnosticism. These difficulties have led to the increasing popularity of so-called ‘imprecise’ models of decision-making, which represent belief states as sets of probability functions. In a recent paper, however, Adam Elga has argued in favour of a putative normative principle of sequential choice that he claims to be borne out (...) by the sharp model but not by any promising incarnation of its imprecise counterpart. After first pointing out that Elga has fallen short of establishing that his principle is indeed uniquely borne out by the sharp model, I cast aspersions on its plausibility. I show that a slight weakening of the principle is satisfied by at least one, but interestingly not all, varieties of the imprecise model and point out that Elga has failed to motivate his stronger commitment.

The mental health crisis and loneliness epidemic have sparked a growing interest in leveraging artificial intelligence (AI) and chatbots as a potential solution. This report examines the benefits and risks of incorporating chatbots in mental health treatment. AI is used for mental health diagnosis and treatment decision-making and to train therapists on virtual patients. Chatbots are employed as always-available intermediaries with therapists, flagging symptoms for human intervention. But chatbots are also sold as stand-alone virtual therapists or as friends and lovers. (...) There is evidence that these uses of AI and chatbots can provide better quality service, improve accessibility, and lower costs. The systems can reduce the stigma and shame of sharing their problems and leverage a mass of biometric and behavioral data to supplement self-reports. As the systems' intelligence rapidly improves, they will need to be rigorously tested for the accuracy and precision of their diagnoses and the quality of their interactions with patients. As chatbots become indistinguishable from humans and leverage their superhuman capacity to detect affect and draw on knowledge of a patient’s life, patients will be drawn to attribute personality to and relationship with the chatbot. Consequently, it will be essential to study what the “therapeutic alliance” with an actual human counselor provides and the risks of patients attributing such a relationship to a one-sided or “parasocial” relationship.

The Procreation Asymmetry holds that we have strong moral reasons not to create miserable people for their own sakes, but no moral reasons to create happy people for their own sakes. To defend this conjunction against an argument that it leads to inconsistency, I show how recognizing ‘creation’ as a temporally extended process allows us to revise the conjuncts in a way that preserves their intuitive force. This defense of the Procreation Asymmetry is preferable to others because it does not (...) require us to take on controversial metaphysical or metaethical commitments – in other words, it has the theoretical virtue of portability.

After a number of decades of research into the dynamics of rational belief, the belief revision theory community remains split on the appropriate handling of sequences of changes in view, the issue of so-called iterated revision. It has long been suggested that the matter is at least partly settled by facts pertaining to the results of various single revisions of one’s initial state of belief. Recent work has pushed this thesis further, offering various strong principles that ultimately result in a (...) wholesale reduction of iterated to one-shot revision. The present paper offers grounds to hold that these principles should be significantly weakened and that the reductionist thesis should ultimately be rejected. Furthermore, the considerations provided suggest a close connection between the logic of iterated belief change and the logic of evidential relevance. (shrink)

One of the most popular arguments in favor of dualism is the zombie-conceivability argument. It is often argued that the possibility of zombies would entail that mental properties are epiphenomenal. This paper attempts to defuse the argument, offering a model of dualist mental causation which can serve as a basis for a modified, interactionist-friendly zombie argument.

Introductory students regularly endorse naïve skepticism—unsupported or uncritical doubt about the existence and universality of truth—for a variety of reasons. Though some of the reasons for students’ skepticism can be traced back to the student—for example, a desire to avoid engaging with controversial material or a desire to avoid offense—naïve skepticism is also the result of how introductory courses are taught, deemphasizing truth to promote students’ abilities to develop basic disciplinary skills. While this strategy has a number of pedagogical benefits, (...) it prevents students in early stages of intellectual development from understanding truth as a threshold concept. Using philosophy as a case study, I argue that we can make progress against naïve skepticism by clearly discussing how metadisciplinary aims differ at the disciplinary and course levels in a way that is meaningful, reinforced, and accessible.

In a recent pair of publications, Richard Bradley has offered two novel no-go theorems involving the principle of Preservation for conditionals, which guarantees that one’s prior conditional beliefs will exhibit a certain degree of inertia in the face of a change in one’s non-conditional beliefs. We first note that Bradley’s original discussions of these results—in which he finds motivation for rejecting Preservation, first in a principle of Commutativity, then in a doxastic analogue of the rule of modus ponens —are problematic (...) in a significant number of respects. We then turn to a recent U-turn on his part, in which he winds up rescinding his commitment to modus ponens, on the grounds of a tension with the rule of Import-Export for conditionals. Here we offer an important positive contribution to the literature, settling the following crucial question that Bradley leaves unanswered: assuming that one gives up on full-blown modus ponens on the grounds of its incompatibility with Import-Export, what weakened version of the principle should one be settling for instead? Our discussion of the issue turns out to unearth an interesting connection between epistemic undermining and the apparent failures of modus ponens in McGee’s famous counterexamples. (shrink)

I explore how agent-regret and its object—faultlessly harming someone—can call for various responses. I look at two sorts of responses. Firstly, I explore responses that respect the agent’s role as an agent. This revolves around a feature of “it was just an accident”—a common response to agent-regret—that has largely gone ignored in the literature: that it can downplay one’s role as an agent. I argue that we need to take seriously the fact that those who have caused harms are genuine (...) agents, to ignore this fails to allow these agents to move on. Secondly, following Sussman and MacKenzie, I explore responses that benefit the victim. I argue that we should strive to understand how to configure these responses in a way that does not blame the agent. To do this I look at the role of actions in our self-understanding, as people who have done particular things. I end by briefly considering the ways in which tort law and restorative justice might help us to understand how to appropriately respond to accidentally harming someone. I urge that we need to take this as a starting point to find a better way to respond to the agents of faultless harms. (shrink)

A restricted-use mobile device policy for introductory philosophy classrooms is presented and defended. The policy allows students to use devices only during open periods announced by the professor and is based on recent empirical findings on the effects of in-class mobile device use. These results suggest devices are generally detrimental to student learning, though they have targeted benefits for specific tasks. The policy is defended via a discussion of the ethical considerations surrounding device use, a discussion of the policy’s benefits, (...) and responses to potential objections. Avenues for future research are suggested at the conclusion of the discussion. (shrink)

When sporting agents fail through wrongful or faulty behaviour, they should feel guilty; when they fail because of a deficiency in their abilities, they should feel shame. But sometimes we fail without being deficient and without being at fault. I illustrate this with two examples of players, Moacir Barbosa and Roberto Baggio, who failed in World Cup finals and cost their teams the greatest prize in sport. Although both players failed, I suggest that neither was at fault and neither was (...) deficient. I argue that we can fail through no fault of our own because our abilities are always fallible. This fallibility means that to succeed – to achieve sporting glory – we must run the risk of failure. The appropriate emotion to feel over such failures is agent-regret. Sporting agents and observers should not take up what I call the ‘critical position’: the idea that someone who fails must be deficient or must have been at fault. This allows for a softer, but also more accurate, attitude towards our own failures and the failures of others. I end by suggesting that the fallibility of our abilities is made clear through playing or watching sport, and this can illuminate life more broadly. (shrink)

In this paper I examine John Rawls’s understanding of desert. Against Samuel Scheffler, I maintain that the reasons underlying Rawls’s rejection of the traditional view of distributive desert in A Theory of Justice also commit him to rejecting the traditional view of retributive desert. Unlike Rawls’s critics, however, I view this commitment in a positive light. I also argue that Rawls’s later work commits him to rejecting retributivism as a public justification for punishment.

Clinical researchers should help respect the autonomy and promote the well-being of prospective study participants by helping them make voluntary, informed decisions about enrollment. However, participants often exhibit poor understanding of important information about clinical research. Bioethicists have given special attention to “misconceptions” about clinical research that can compromise participants’ decision-making, most notably the “therapeutic misconception.” These misconceptions typically involve false beliefs about a study’s purpose, or risks or potential benefits for participants. In this article, we describe a misconception involving (...) false beliefs about a study’s potential benefits for non-participants, or its expected social value. This social value misconception can compromise altruistically motivated participants’ decision-making, potentially threatening their autonomy and well-being. We show how the social value misconception raises ethical concerns for inherently low-value research, hyped research, and even ordinary research, and advocate for empirical and normative work to help understand and counteract this misconception’s potential negative impacts on participants.

There is wide consensus among bioethicists about the importance of autonomy when determining whether or not a patient has the right to refuse life-saving treatment (LST). In this context, autonomy has typically been understood in terms of the patient’s ability to make an informed decision. According to the traditional view, decision-making capacity (DMC) is seen as both necessary and sufficient for the right to refuse LST. Recently, this view has been challenged by those who think that considerations of authenticity and (...) putative counterexamples should lead us to revise the traditional account. In this paper, we respond to these revisionist arguments, and we defend the traditional view according to which we have autonomy-based reasons to respect a patient’s decision to refuse LST if and only if she has DMC.

Innovative practice occurs when a clinician provides something new, untested, or nonstandard to a patient in the course of clinical care, rather than as part of a research study. Commentators have noted that patients engaged in innovative practice are at significant risk of suffering harm, exploitation, or autonomy violations. By creating a pathway for harmful or nonbeneficial interventions to spread within medical practice without being subjected to rigorous scientific evaluation, innovative practice poses similar risks to the wider community of patients (...) and society as a whole. Given these concerns, how should we control and oversee innovative practice, and in particular, how should we coordinate innovative practice and clinical research? In this article, I argue that an ethical approach to overseeing innovative practice must encourage the early transition to rigorous clinical research without delaying or deferring the development of beneficial innovations or violating the autonomy rights of clinicians and their patients.

According to a classic but nowadays discarded philosophical theory, perceptual experience is a complex of nonconceptual sensory states and full-blown propositional beliefs. This classical dual-component theory of experience is often taken to be obsolete. In particular, there seem to be cases in which perceptual experience and belief conflict: cases of known illusions, wherein subjects have beliefs contrary to the contents of their experiences. Modern dual-component theories reject the belief requirement and instead hold that perceptual experience is a complex of nonconceptual (...) sensory states and some other sort of conceptual state. The most popular modern dual-component theory appeals to sui generis propositional attitudes called ‘perceptual seemings’. This article argues that the classical dual-component theory has the resources to explain known illusions without giving up the claim that the conceptual components of experience are beliefs. The classical dual-component view, though often viewed as outdated and implausible, should be regarded as a serious contender in contemporary debates about the nature of perceptual experience.

I argue, contra traditional interpretations of James's emotion theory like Antonio Damasio and alternative interpretations like Phoebe Ellsworth and Lisa Barrett, that James is best classified as a functionalist regarding emotion categories. In arguing for this point, I will make four textual claims: (1) James was an important precursor to Basic Emotion Theory (BET) and his theory is best identified as a flavor of BET; (2) James's theory individuates emotion categories by their evolutionary, functional roles; (3) The only necessary condition (...) on something being an emotion is that it is a bodily feeling; and, (4) Contrary to Barrett and Ellsworth, James was loath to offer a definitive list of basic emotions not because he loathed taxonomy but rather because he thought psychology was not yet a natural science with well-defined theoretical categories. I close by arguing that a proper understanding of James's emotion theory defangs some critiques of BET and of Neo-Jamesian theory. (shrink)

I argue that sports clubs should be punished for bad behaviour by their fans in a way that affects the club’s sporting success: for example, we are justified in imposing points deductions and competition disqualifications on the basis of racist chanting. This is despite a worry that punishing clubs in such a way is unfair because it targets the sports team rather than the fans who misbehaved. I argue that this belies a misunderstanding of the nature of sports clubs and (...) of the nature of sporting success. Further, I argue that fans should want to be held responsible in such a way because it vindicates the significant role that they play in the life of their club. (shrink)

Unconscious logical inference seems to rely on the syntactic structures of mental representations (Quilty-Dunn & Mandelbaum 2018). Other transitions, such as transitions using iconic representations and associative transitions, are harder to assimilate to syntax-based theories. Here we tackle these difficulties head on in the interest of a fuller taxonomy of mental transitions. Along the way we discuss how icons can be compositional without having constituent structure, and expand and defend the “symmetry condition” on Associationism (the idea that associative links and (...) transitions are perfectly symmetric). In the end, we show how a BIT (“bare inferential transition”) theory can cohabitate with these other non-inferential mental transitions. (shrink)

Extended Reality (XR) and Large Language Model (LLM) technologies have the potential to significantly influence higher education practices and pedagogy in the coming years. As these emerging technologies reshape the educational landscape, it is crucial for educators and higher education professionals to understand their implications and make informed policy decisions for both individual courses and universities as a whole. -/- This paper has two parts. In the first half, we give an overview of XR technologies and their potential future role (...) in higher education. Then, we discuss the benefits and challenges of adopting and integrating XR technologies into higher education settings. Finally, we offer recommendations for educators, administrators, and policymakers on how to approach the adoption of this set of technologies and set institutional policy to take advantage of its benefits while minimizing its potential negative consequences. -/- In the paper’s second half, we discuss LLMs - specifically Generative Pre-trained Transformers (GPTs). Again, we provide an overview of this rapidly developing technology and examine its unprecedented and potentially disruptive impact on higher education pedagogy. We delve into the benefits and limitations of GPTs, highlighting the pedagogical and ethical challenges they may pose. Finally, we present actionable recommendations for instructors and administrators at both the course level and the university-wide level to guide policy decisions concerning these transformative technologies.

I explore what BernardWilliams means by regarding one’s action ‘purely externally, as one might regard anyone else’s action’, and how it links to regret and agent-regret. I suggest some ways that we might understand the external view: as a failure to recognize what one has done, in terms of Williams’s distinction between intrinsic and extrinsic luck, and as akin to Thomas Nagel’s distinction between an internal and external view. I argue that none of these captures what Williams was getting at (...) because they do not allow one to take a view on one’s action. I offer two alternative accounts. One turns around what we identify with, the other concerns what we care about. Both accounts capture how I might regret, rather than agent-regret, my own action. I demonstrate that these accounts can explain the relationship between an insurance payout and the external view, and they can explain the agent-relativity of agent-regret. (shrink)

This manuscript discusses the author’s experience implementing a secularized version of Lectio Divina, a medieval monastic contemplative reading practice, in an introductory philosophy classroom. Following brief discussion of Lectio Divina’s history and a description of how the practice was modified for the classroom, I discuss three benefits (increased attention to cognitive and noncognitive reactions to the text, willingness to engage with the material in novel ways, and the opportunity to engage in independent disciplinary practice) and three potential challenges (the time (...) required, student engagement, and the practice’s perceived religiosity) arising from the exercise. Following this, I discuss potential modifications to the exercise that instructors may wish to consider, namely strategies for addressing students’ status as novice meditators, focusing textual selections on course materials, and having students engage in some aspects of the practice as homework.

Sporting competitions have been beset by change due to COVID-19. Some commentators and sportspeople worried that this affected the integrity of these competitions. Focussing on European football, I suggest that one way of understanding integrity is in terms of fairness. I argue that many changes introduced a form of luck that is already common and widespread and that many changes were also justified. Thus, they did not affect the integrity of these competitions in this way. I then suggest that there (...) is another integrity issue lurking: that the changes affected the character of these competitions, rendering them unrecognizable. I briefly explore this issue.

This essay presents deductive arguments to an introductory-level audience via a discussion of Aristotle's three types of rhetoric, the goals of and differences between deductive and non-deductive arguments, and the major features of deductive arguments (e.g., validity and soundness).

Several philosophers have recently argued that policies aimed at reducing human fertility are a practical and morally justifiable way to mitigate the risk of dangerous climate change. There is a powerful objection to such “population engineering” proposals: even if drastic fertility reductions are needed to prevent dangerous climate change, implementing those reductions would wreak havoc on the global economy, which would seriously undermine international antipoverty efforts. In this article, we articulate this economic objection to population engineering and show how it (...) fails. We argue, first, that the economic objection paints an inaccurate picture of the complicated relationship between demographic change and economic growth, and second, that any untoward economic effects of fertility reduction can be mitigated with additional policies. Specifically, we argue that supplementing fertility reduction with policies that facilitate the emigration of younger people from developing nations to developed nations could allow for both global reductions in GHG emissions and continued economic stability. Further, we show that moral arguments against such unprecedented increases in immigration are unsuccessful. We conclude that population engineering is a practical and morally justifiable tool for addressing the twin evils of climate change and global poverty. (shrink)

Many contemporary ethical debates turn on claims about the nature and extent of our alleged procreative moral rights: moral rights to procreate or not to procreate as we choose. In this article, I argue that there are no procreative moral rights, in that generally we do not have a distinctive moral right to procreate or not to procreate as we choose. However, interference with our procreative choices usually violates our nonprocreative moral rights, such as our moral rights to bodily autonomy (...) or to privacy. My argument presents hypothetical cases in which a state interferes with a person's procreative choices in order to promote aggregate social welfare, but this interference does not violate any of the person's nonprocreative moral rights. These cases not only undermine frequently made claims that widely recognized nonprocreative moral rights entail procreative moral rights, they also challenge the intuitively plausible claim that interference with our procreative choices as such violates our moral rights. What at first appear to be substantive moral rights are in fact a kind of illusion created by the frequent overlap of other rights, but lacking in substance beyond that overlap. While this argument against the existence of procreative moral rights has substantive implications for ongoing debates in reproductive ethics, I ultimately suggest that it is consistent with a progressive approach to reproductive justice.

This Ideas and Opinions article revisits an argument from Judith Jarvis Thomson in her essay “A Defense of Abortion” that abortion can be an ethical choice even if we assume that fetuses have full moral personhood and moral rights. The authors examine the implications of laws that require a pregnant person to care for another with their body and what other impositions states may also require of citizens to care for others.

The field of iterated belief change has focused mainly on revision, with the other main operator of AGM belief change theory, i.e. contraction, receiving relatively little attention. In this paper we extend the Harper Identity from single-step change to define iterated contraction in terms of iterated revision. Specifically, just as the Harper Identity provides a recipe for defining the belief set resulting from contracting A in terms of (i) the initial belief set and (ii) the belief set resulting from revision (...) by ¬A, we look at ways to define the plausibility ordering over worlds resulting from contracting A in terms of (iii) the initial plausibility ordering, and (iv) the plausibility ordering resulting from revision by ¬A. After noting that the most straightforward such extension leads to a trivialisation of the space of permissible orderings, we provide a family of operators for combining plausibility orderings that avoid such a result. These operators are characterised in our domain of interest by a pair of intuitively compelling properties, which turn out to enable the derivation of a number of iterated contraction postulates from postulates for iterated revision. We finish by observing that a salient member of this family allows for the derivation of counterparts for contraction of some well known iterated revision operators, as well as for defining new iterated contraction operators.

How should sport deal with prematurely ended seasons? This question is especially relevant to the current COVID-19 inter- ruption that threatens to leave many leagues without cham- pions. We argue that although there can be no winners, in certain situations there should be champions. Relevant to the current situation, we argue that Liverpool FC—currently with a 22+ point lead—should be crowned champions of the English Premier League. However, things are not as simple as simply handing the championship to whoever was (...) in the lead when a season is prematurely ended. Through analogy with a fictional decathlon competition—and with the understanding that sporting seasons are themselves a type of game—we identify three reasons why leading at the moment of cessation is insufficient to be crowned a victor (of an individual event) or a champion (of a season-long competition): doing so fails to respect some valuable skills, fails to allow for luck to play out in an interesting way that affects competitions, and fails to respect competitive strategies. This discussion can then inform determining what, if any, end-of-season accolades are relevant, such as championships, relegation, or promotion. No team can win in a league that has failed to be completed, but there can still be a champion. (shrink)

‘Fake news’ has become an increasingly common refrain in public discourse, though the term itself has several uses, at least one of which constitutes Frankfurtian bullshit. After examining what sorts of fake news appeals do and do not count as bullshit, I discuss strategies for overcoming our openness to such bullshit. I do so by drawing a parallel between openness to bullshit and naïve skepticism—one’s willingness to reject the concept of truth on unsupported or ill-considered grounds—and suggest that this parallel (...) indicates three principles for how we ought to combat our openness to fake news and other bullshit. First, the root causes of bullshit openness are not monolithic; we should adopt anti-bullshit strategies in recognition of this fact. Second, our efforts to overcome bullshit openness should be collaborative efforts to create an environment that allows for sustained interrogation of our bullshit openness, rather than a confrontational provision of contrary evidence, despite the fact that such strategies are more time-intensive. Third, social media is unlikely to be a fertile ground on which we will make meaningful progress in the fight against bullshit because of the inherent nature of social media platforms as spaces for short, declarative, confrontational claims.

The case (Dawson et al. 2024) describes an Institutional Review Board (IRB) chair who seeks consultation about waiving the requirement that investigators obtain prospective, informed consent for collection of microbiome samples by swabbing the perianal region of severely burned patients shortly after their admission to an intensive care unit (ICU). We argue that it is ethically permissible to waive informed consent requirements for the perianal swab and that the IRB should approve a waiver as permitted by regulations.

Abstract: This paper develops and advocates a rule for assigning self-locating credences in quantum branching scenarios, called Indexed Branch-Counting. It is argued that Indexed Branch-Counting can be justified on both accuracy-theoretic grounds and on the grounds that it satisfies a requirement of exchangeability for probability assignments. Since Indexed Branch-Counting diverges from the Born Rule, this poses trouble for Everettian approaches to probability. The paper also addresses a common argument against branch-counting, namely that the rule is incoherent in light of putative (...) vagueness in the number of branches. Finally, the paper addresses a recent proposal from Simon Saunders that aims to reconcile branch-counting with the Born Rule, arguing that the proposal faces challenges. (shrink)

Reductive accounts of the direction of time are often paired with Humean accounts of laws, while non-reductive accounts of time are often paired with anti-Humean accounts of laws. The traditional pairing of views has recently come under question. This paper aims to clarify what sorts of anti-Humean views motivate anti-reductionism about the direction of time. It is argued that those who think (i) that the laws are metaphysically fundamental, and (ii) that the laws contain time-asymmetric contents, should treat the arrow (...) of time as metaphysically fundamental.

Mental representations remain the central posits of psychology after many decades of scrutiny. However, there is no consensus about the representational format(s) of biological cognition. This paper provides a survey of evidence from computational cognitive psychology, perceptual psychology, developmental psychology, comparative psychology, and social psychology, and concludes that one type of format that routinely crops up is the language-of-thought (LoT). We outline six core properties of LoTs: (i) discrete constituents; (ii) role-filler independence; (iii) predicate–argument structure; (iv) logical operators; (v) inferential (...) promiscuity; and (vi) abstract content. These properties cluster together throughout cognitive science. Bayesian computational modeling, compositional features of object perception, complex infant and animal reasoning, and automatic, intuitive cognition in adults all implicate LoT-like structures. Instead of regarding LoT as a relic of the previous century, researchers in cognitive science and philosophy-of-mind must take seriously the explanatory breadth of LoT-based architectures. We grant that the mind may harbor many formats and architectures, including iconic and associative structures as well as deep-neural-network-like architectures. However, as computational/representational approaches to the mind continue to advance, classical compositional symbolic structures – that is, LoTs – only prove more flexible and well-supported over time.

Darwiche and Pearl’s seminal 1997 article outlined a number of baseline principles for a logic of iterated belief revision. These principles, the DP postulates, have been supplemented in a number of alternative ways. Most suggestions have resulted in a form of ‘reductionism’ that identifies belief states with orderings of worlds. However, this position has recently been criticised as being unacceptably strong. Other proposals, such as the popular principle (P), aka ‘Independence’, characteristic of ‘admissible’ operators, remain commendably more modest. In this (...) paper, we supplement the DP postulates and (P) with a number of novel conditions. While the DP postulates constrain the relation between a prior and a posterior conditional belief set, our new principles notably govern the relation between two posterior conditional belief sets obtained from a common prior by different revisions. We show that operators from the resulting family, which subsumes both lexicographic and restrained revision, can be represented as relating belief states associated with a ‘proper ordinal interval’ (POI) assignment, a structure more fine-grained than a simple ordering of worlds. We close the paper by noting that these operators satisfy iterated versions of many AGM era postulates, including Superexpansion, that are not sound for admissible operators in general. (shrink)

I argue that campus closures and shifts to online instruction in the early stages of the COVID-19 pandemic created an obligation to offer courses asynchronously. This is because some students could not have reasonably foreseen circumstances making continued synchronous participation impossible. Offering synchronous participation options to students who could continue to participate thusly would have been unfair to students who could not participate synchronously. I also discuss why ex post facto consideration of this decision is warranted, noting that similar actions (...) may be necessary in the future and that other tough pedagogical cases share important similarities with this case.

Although researchers generally take great care to ensure that human subjects do not suffer very serious harms from their involvement in research, the situation is different for nonhuman animal subjects. Significant progress has been made in reducing unnecessary animal suffering in research, yet researchers still inflict severe pain and distress on tens of thousands of animals every year for scientific purposes. Some bioethicists, scientists, and animal welfare advocates argue for placing an upper limit on the suffering researchers may impose on (...) animal subjects, with rare exceptions for research that promises critical social benefits. In this article, I argue against such an upper limit on harm on the grounds that researchers often can compensate animal subjects for their suffering, even severe and long-lasting suffering. If animal subjects receive adequate compensation for the harms they suffer, then there is no general limit on how much suffering researchers may impose on them for scientific purposes. (shrink)

Review of Yaffe's "The Age of Culpability".

The case describes researchers who are seeking ethics guidance on communicating with participants in a phase-1 COVD-19 vaccine trial about FDA-authorized COVID-19 vaccines (Wilfond, Duenas, and Johnson 2023). The researchers want help choosing among three options they have identified for encouraging participants to obtain one of the authorized vaccines. We argue that research ethics consultants should consider going beyond this question to address another ethics concern the researchers might have overlooked.

Perceptual systems respond to proximal stimuli by forming mental representations of distal stimuli. A central goal for the philosophy of perception is to characterize the representations delivered by perceptual systems. It may be that all perceptual representations are in some way proprietarily perceptual and differ from the representational format of thought (Dretske 1981; Carey 2009; Burge 2010; Block ms.). Or it may instead be that perception and cognition always trade in the same code (Prinz 2002; Pylyshyn 2003). This paper rejects (...) both approaches in favor of perceptual pluralism, the thesis that perception delivers a multiplicity of representational formats, some proprietary and some shared with cognition. The argument for perceptual pluralism marshals a wide array of empirical evidence in favor of iconic (i.e., image-like, analog) representations in perception as well as discursive (i.e., language-like, digital) perceptual object representations.

Innovative practice involves medical interventions that deviate from standard practice in significant ways. For many patients, innovative practice offers the best chance of successful treatment. Because little is known about most innovative treatments, clinicians who engage in innovative practice might consider including extra procedures, such as scans or blood draws, to gather information about the innovation. Such information-gathering interventions can yield valuable information for modifying the innovation to benefit future patients and for designing scientific studies of the innovation. However, existing (...) guidelines do not say when or whether it is appropriate to add potentially risky information-gathering interventions for these purposes. As a result, clinicians may assume that information-gathering interventions are ethically inappropriate and should not be used in innovative practice. This assumption can lead to seriously negative consequences, such as increasing the likelihood that harmful or ineffective innovations will be adopted and creating new barriers to the development of genuinely beneficial treatments. We argue that health care institutions need to promote the responsible use of information-gathering interventions as an adjunct to innovative practice, and that these interventions are not clinical research and should not be subject to research oversight.
