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)

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)

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.

Since his Metaphysische Anfangsgründe der Naturwissenschaft was first published in 1786, controversy has surrounded Immanuel Kant’s conception of matter. In particular, the justification for both his dynamical theory of matter and the related dismissal of mechanical philosophy are obscure. In this paper, I address these longstanding issues and establish that Kant’s dynamism rests upon Leibnizian, metaphysical commitments held by Kant from his early pre-Critical texts on natural philosophy to his major critical works. I demonstrate that, throughout his corpus and inspired (...) by Leibniz, Kant endorses the a priori law of continuity of alteration as a truth of metaphysics, according to which all alterations in experience must occur gradually through all intervening degrees. The principle thus legislates against mechanical philosophy’s absolutely impenetrable atoms, as they would would involve instantaneous changes of velocity in impact. This reveals the metaphysical incoherencies in mechanical philosophy and leaves Kant’s own dynamical theory of matter, grounded on material forces, as the only viable approach to physical explanation. Subsequently, I demonstrate that Kant nevertheless made conceptual space in his system for the theoretical consideration of mechanical explanations, which makes manifest one of the positive roles that the faculty of reason can play with respect to natural science.

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)

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 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.

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)

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.

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.

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)

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.

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)

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).

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)

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.

‘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.

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.

I argue for a novel understanding of the nature of agent-regret. On the standard picture, agent-regret involves regretting the result of one’s action and thus regretting one’s action. I argue that the standard picture is a flawed analysis of agent-regret. I offer several cases of agent-regret where the agent feels agent-regret but does not regret the result itself. I appeal to other cases where an agent’s attitude towards something depends upon whether or not they are involved in that thing. I (...) argue that the same applies to actions: sometimes an agent’s attitude towards a result differs from their attitude to their involvement in bringing about that result. Agent-regret is regret about my own action, but it need not involve regret about something in the world. I end by considering how this picture of agent-regret allows us to respond to a particular criticism of agent-regret. (shrink)

Peter Lamarque, in chapter 4 of his 2010 book Work and Object, argues that certain artworks, like musical scores and literary texts, are such that there can be no forgeries of them that purport to be of an actually existing work—what Lamarque calls “referential forgeries”. Lamarque motivates this claim via appeal to another distinction, first made by Goodman, between “allographic” and “autographic” artworks. This article will evaluate Lamarque’s argument that allographic literary works are unable to be referentially forged and will (...) find them wanting. In so doing, the distinction between allographic and autographic artworks (and therefore artforms) will be called into question. In section I, I characterize referential forgery and Lamarque’s definition of allographic and autographic artforms. Section II critically examines Lamarque’s argument against the possibility of referential forgery in allographic artforms. Section III offers a case where it appears that a putatively allographic text’s type membership is sensitive to facts about its causal-intentional provenance. This case serves as pretext for Section IV’s identification of this causal-intentional relation with the sanctioning relation as formulated by Sherri Irvin. On the basis of considerations treated in sections I through IV, section V questions the tenability of the allographic/autographic distinction. -/- . (shrink)

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.

What makes democracy valuable? One traditional answer holds that participating in democratic self-government amounts to a kind of autonomy: it enables citizens to be the authors of their political affairs. Many contemporary philosophers, however, are skeptical. We are autonomous, they argue, when important features of our lives are up to us, but in a democracy we merely have a say in a process of collective choice. In this paper, we defend the possibility of democratic autonomy, by advancing a conception of (...) it which is impervious to this objection. At the core of our account is the idea of joint authorship. You are a joint author of something when that thing expresses your joint intentions. Democracy may not make any one of us sole author of our political affairs, but it can make us their joint authors. It is in such joint authorship, we claim, that the intrinsic value of democratic self-government consists. (shrink)

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)

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.

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)

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)

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.

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)

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.

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

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)

This chapter develops an account of epistemic nihilism—roughly, the rejection of truth’s intrinsic or instrumental value in favor of statements that reject or obscure truth to secure an advantage for the speaker—by examining three instances of such nihilism: lying, bullshit, and trolling. It further argues that epistemic nihilism, exacerbated by changes in the media landscape, can pose a significant threat to liberal democratic institutions and ideals by undermining the democratic ideal of good faith engagement on a level playing field, while (...) also encouraging undemocratic actions (e.g., terrorism) among interlocutors who take the nihilist’s claims seriously. Finally, this chapter argues that in extreme cases, we are justified in denying epistemic nihilists a platform from which to speak by drawing a parallel with vexatious litigant laws that deny individuals the right to petition courts for redress on the grounds that abuse of that right results in significant harm to both individuals and the legal system itself.

Progressive stacking is a strategy for prioritizing in-class contributions that allows marginalized students to speak before non-marginalized students. I argue that this strategy is both pedagogically and ethically defensible. Pedagogically, it provides benefits to all students (e.g., expanded in-class discourse) while providing special benefits (e.g., increased self-efficacy) to marginalized students, helping to address historic educational inequalities. Ethically, I argue that neither marginalized nor non-marginalized students are wronged by such a policy. First, I present a strategy for self-disclosure that reduces the (...) risk of inadvertent, unwanted disclosure while respecting marginalized student autonomy in a manner analogous to accommodations provided under the Americans with Disabilities Act. Second, I argue that non-marginalized students are not wronged because such students are not silenced during discussion and because non-marginalized students benefit from the prioritization of marginalized voices.

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.

Philosophy as a way of life (PWOL) places investigations of value, meaning, and the good life at the center of philosophical investigation, especially of one’s own life. I argue PWOL is compatible with general introductory philosophy courses, further arguing that PWOL-based general introductions have several philosophical and pedagogical benefits. These include the ease with which high impact practices, situated skill development, and students’ ability to ‘think like a disciplinarian’ may be incorporated into such courses, relative to more traditional introductory courses, (...) as well as the demonstration of philosophy’s value to students by explicitly tying philosophical investigation to students own lives.

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.

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.

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.

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)

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.

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.

This dissertation is a defence of agent-regret and an exploration of its role in our lives. I argue that agent-regret shows that an agent takes seriously her status as an agent who impacts the world, but who only has fallible control over it. To accept responsibility for any outcomes, she must accept responsibility for unintended outcomes, too: agent-regret is part of being a human agent. In doing this, I try to defend and develop Williams’s own conception of agent-regret. -/- In (...) the first part, I explore the nature of agent-regret. Agent-regret is distinct from guilt because we can feel agent-regret without being at fault. I argue that several challenges that seek to reduce agent-regret to a form of guilt fail. I further argue that agent-regret takes as its object not only something one has done, but the fact that one did it; I discuss this in terms of what Bernard Williams called taking an “external” view on one’s own action. -/- I suggest that we can best understand the object of agent-regret as one’s responsibility for an outcome. I argue that this form of “responsibility” is conceptually separate from liability or answerability; it concerns whether the outcome can be ascribed to an agent. This is a restricted form of causal responsibility but retains its agential character. I suggest that we can be responsible for outcomes even when we did not intend to bring them about. -/- In the second part, I vindicate the propriety of agent-regret against the ideas that we are not responsible for unintended outcomes or that such responsibility is not important. I set out several challenges to this effect. I argue that we are responsible for unintended outcomes because in order to be responsible as agents at all, we must use fallible abilities. When we exercise these abilities but fail, we are responsible as agents for those unintended outcomes that arise. I then consider the importance of being responsible for particular unintended outcomes and analyse the idea that this affects our identities. I argue that responsibility for an outcome affects a form of identity, but that it does not involve essential features of a person. Instead, our responsibility for outcomes is a contingent feature that nonetheless plays an important role in our interpersonal interactions and self-conceptions. I argue that these reactions are appropriate, because our responsibility for particular outcomes is independently significant—but these reactions also lend this responsibility added significance as part of inescapable human practices. -/- Thus our responsibility for outcomes is important. Its importance means that it can serve as an appropriate object of agent-regret that vindicates the propriety of agent-regret. I end by considering several interesting features of agent-regret, including its expression and “pure” cases, which are cases where an agent feels agent-regret despite not regretting the result of her action.

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.

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)
