Research integrating cognitive abilities and personality has focused on the role of personality traits. We propose a theory on the role of intraindividual variability of personality states (hereafter state variability) on perspective taking, in particular, the ability to infer other peoples’ mental states. First, we review the relevant research on personality psychology and social cognition. Second, we propose two complementary routes by which state variability relates to anchoring and adjustment in perspective taking. The first route, termed ego-dispersion, suggests that an (...) increased state variability decreases egocentric bias, which reduces anchoring. The second route, termed perspective-pooling, suggests that an increased state variability facilitates efficient adjustment. We also discuss how our theory can be investigated empirically. The theory is rooted in an ecological interpretation of personality and social cognition, and flags new ways for integrating these fields of research. (shrink)

Hilbert’s program was an ambitious and wide-ranging project in the philosophy and foundations of mathematics. In order to “dispose of the foundational questions in mathematics once and for all,” Hilbert proposed a two-pronged approach in 1921: first, classical mathematics should be formalized in axiomatic systems; second, using only restricted, “finitary” means, one should give proofs of the consistency of these axiomatic systems. Although Gödel’s incompleteness theorems show that the program as originally conceived cannot be carried out, it had many partial (...) successes, and generated important advances in logical theory and metatheory, both at the time and since. The article discusses the historical background and development of Hilbert’s program, its philosophical underpinnings and consequences, and its subsequent development and influences since the 1930s.

Logic has pride of place in mathematics and its 20th century offshoot, computer science. Modern symbolic logic was developed, in part, as a way to provide a formal framework for mathematics: Frege, Peano, Whitehead and Russell, as well as Hilbert developed systems of logic to formalize mathematics. These systems were meant to serve either as themselves foundational, or at least as formal analogs of mathematical reasoning amenable to mathematical study, e.g., in Hilbert’s consistency program. Similar efforts continue, but have been (...) expanded by the development of sophisticated methods to study the properties of such systems using proof and model theory. In parallel with this evolution of logical formalisms as tools for articulating mathematical theories (broadly speaking), much progress has been made in the quest for a mechanization of logical inference and the investigation of its theoretical limits, culminating recently in the development of new foundational frameworks for mathematics with sophisticated computer-assisted proof systems. In addition, logical formalisms developed by logicians in mathematical and philosophical contexts have proved immensely useful in describing theories and systems of interest to computer scientists, and to some degree, vice versa. Three examples of the influence of logic in computer science are automated reasoning, computer verification, and type systems for programming languages. (shrink)

The proof theory of many-valued systems has not been investigated to an extent comparable to the work done on axiomatizatbility of many-valued logics. Proof theory requires appropriate formalisms, such as sequent calculus, natural deduction, and tableaux for classical (and intuitionistic) logic. One particular method for systematically obtaining calculi for all finite-valued logics was invented independently by several researchers, with slight variations in design and presentation. The main aim of this report is to develop the proof theory of finite-valued first order (...) logics in a general way, and to present some of the more important results in this area. In Systems covered are the resolution calculus, sequent calculus, tableaux, and natural deduction. This report is actually a template, from which all results can be specialized to particular logics. (shrink)

Methods available for the axiomatization of arbitrary finite-valued logics can be applied to obtain sound and complete intelim rules for all truth-functional connectives of classical logic including the Sheffer stroke and Peirce’s arrow. The restriction to a single conclusion in standard systems of natural deduction requires the introduction of additional rules to make the resulting systems complete; these rules are nevertheless still simple and correspond straightforwardly to the classical absurdity rule. Omitting these rules results in systems for intuitionistic versions of (...) the connectives in question. (shrink)

Research programs in empirical psychology from the past two decades have revealed implicit biases. Although implicit processes are pervasive, unavoidable, and often useful aspects of our cognitions, they may also lead us into error. The most problematic forms of implicit cognition are those which target social groups, encoding stereotypes or reflecting prejudicial evaluative hierarchies. Despite intentions to the contrary, implicit biases can influence our behaviours and judgements, contributing to patterns of discriminatory behaviour. These patterns of discrimination are obviously wrong and (...) unjust. But in remedying such wrongs, one question to be addressed concerns responsibility for implicit bias. Unlike some paradigmatic forms of wrongdoing, such discrimination is often unintentional, unendorsed, and perpetrated without awareness; and the harms are particularly damaging because they are cumulative and collectively perpetrated. So, what are we to make of questions of responsibility? In this article, we outline some of the main lines of recent philosophical thought, which address questions of responsibility for implicit bias. We focus on (a) the kind of responsibility at issue; (b) revisionist versus nonrevisionist conceptions of responsibility as applied to implicit bias; and (c) individual, institutional, and collective responsibility for implicit bias. (shrink)

Philosophers who have written about implicit bias have claimed or implied that individuals are not responsible, and therefore not blameworthy, for their implicit biases, and that this is a function of the nature of implicit bias as implicit: below the radar of conscious reflection, out of the control of the deliberating agent, and not rationally revisable in the way many of our reflective beliefs are. I argue that close attention to the findings of empirical psychology, and to the conditions for (...) blameworthiness, does not support these claims. I suggest that the arguments for the claim that individuals are not liable for blame are invalid, and that there is some reason to suppose that individuals are, at least sometimes, liable to blame for the extent to which they are influenced in behaviour and judgment by implicit biases. I also argue against the claim that it is counter-productive to see bias as something for which individuals are blameworthy; rather, understanding implicit bias as something for which we are liable to blame could be constructive.

Do participants in shared activity have mutual obligations to do their bit? This article shows this question has no one-size-fits-all answer and offers a pluralist account of the normativity of shared agency. The first part argues obligations to do one's bit have three degrees of involvement in shared activity. Such obligations might, obviously, bolster co-participants’ resolve to act as planned (degree 1). Less obviously, there also are higher and lower degrees of involvement. Obligations to do one's bit might provide our (...) agency-pooling mechanism. When they do, we act together by virtue of satisfying them (degree 2). Conversely, some shared activities involve no obligation (degree 0). In the second part, I argue shared agency theory is best served by a non-moralistic conception of obligation, one on which co-participants’ obligations need be neither strict-performance obligations, nor directed ones. Overall, my arguments suggest that we can choose how to coordinate normatively our shared activities. (shrink)

The term 'implicit bias' has very swiftly been incorporated into philosophical discourse. Our aim in this paper is to scrutinise the phenomena that fall under the rubric of implicit bias. The term is often used in a rather broad sense, to capture a range of implicit social cognitions, and this is useful for some purposes. However, we here articulate some of the important differences between phenomena identified as instances of implicit bias. We caution against ignoring these differences: it is likely (...) they have considerable significance, not least for the sorts of normative recommendations being made concerning how to mitigate the bad effects of implicit bias. (shrink)

Our focus here is on whether, when influenced by implicit biases, those behavioural dispositions should be understood as being a part of that person’s character: whether they are part of the agent that can be morally evaluated.[4] We frame this issue in terms of control. If a state, process, or behaviour is not something that the agent can, in the relevant sense, control, then it is not something that counts as part of her character. A number of theorists have argued (...) that individuals do not have control, in the relevant sense, over the operation of implicit bias. We will argue that this claim is mistaken. We articulate and develop a notion of control that individuals have with respect to implicit bias, and argue that this kind of control can ground character-based evaluation of such behavioural dispositions. (shrink)

Philosophers have had a lot to say about blame, much less about praise. In this paper, I follow some recent authors in arguing that this is a mistake. However, unlike these recent authors, the reasons I identify for scrutinising praise are to do with the ways in which praise is, systematically, unjustly apportioned. Specifically, drawing on testimony and findings from social psychology, I argue that praise is often apportioned in ways that reflect and entrench existing structures of oppression. Articulating what (...) is going wrong here helps us to see what to do about it. (shrink)

Drawing on a passage from Ramsey's Truth and Probability, we formulate a simple, plausible constraint on evaluating the accuracy of credences: the Calibration Test. We show that any additive, continuous accuracy measure that passes the Calibration Test will be strictly proper. Strictly proper accuracy measures are known to support the touchstone results of accuracy-first epistemology, for example vindications of probabilism and conditionalization. We show that our use of Calibration is an improvement on previous such appeals by showing how it answers (...) or sidesteps problems that have been raised for previous work in this area. (shrink)

Recent empirical research has substantiated the finding that very many of us harbour implicit biases: fast, automatic, and difficult to control processes that encode stereotypes and evaluative content, and influence how we think and behave. Since it is difficult to be aware of these processes - they have sometimes been referred to as operating 'unconsciously' - we may not know that we harbour them, nor be alert to their influence on our cognition and action. And since they are difficult to (...) control, considerable work is required to prevent their influence. We here focus on the implications of these findings for epistemology. We first look at ways in which implicit biases thwart our knowledge seeking practices (sections 1 & 2). Then we set out putative epistemic benefits of implicit bias, before considering ways in which epistemic practices might be improved (section 3). Finally, we consider the distinctive challenges that the findings about implicit bias pose to us as philosophers, in the context of feminist philosophy in particular (section 4). (shrink)

Should the state punish its disadvantaged citizens who have committed crimes? Duff has recently argued that where disadvantage persists the state loses its authority to hold individuals to account and to punish for criminal wrongdoings. I here scrutinize Duff’s argument for the claim that social justice is a precondition for the legitimacy of state punishment. I sharpen an objection to Duff’s argument: with his framework, we seem unable to block the implausible conclusion that where disadvantage persists the state lacks the (...) authority to punish any citizen for any crime. I then set out an alternative line of argument in support of the claim that social deprivation can threaten the states legitimate punitive authority. I argue that a penal system must incorporate certain proportionality principles, and that these principles cannot both be met where citizens suffer from deprivation. (shrink)

This chapter evaluates two competing views of morally responsible agency. The first view at issue is Vargas’s circumstantialism—on which responsible agency is a function of the agent and her circumstances, and so is highly context sensitive. The second view is McGeer’s scaffolded-responsiveness view, on which responsible agency is constituted by the capacity for responsiveness to reasons directly, and indirectly via sensitivity to the expectations of one’s audience (whose sensitivity may be more developed than one’s own). This chapter defends a version (...) of the scaffolded-responsiveness view, and develops two further claims. Firstly, moral responsibility should not be tied too closely to liability to praise or blame. Secondly, rather than revising our existing concept of responsibility, we would do better to ask what we want the concept of responsibility for. (shrink)

This paper takes as its focus efforts to address particular aspects of sexist oppression and its intersections, in a particular field: it discusses reform efforts in philosophy. In recent years, there has been a growing international movement to change the way that our profession functions and is structured, in order to make it more welcoming for members of marginalized groups. One especially prominent and successful form of justification for these reform efforts has drawn on empirical data regarding implicit biases and (...) their effects. Here, we address two concerns about these empirical data. First, critics have for some time argued that the studies drawn upon cannot give us an accurate picture of the workings of prejudice, because they ignore the intersectional nature of these phenomena. More recently, concerns have been raised about the empirical data supporting the nature and existence of implicit bias. Each of these concerns, but perhaps more commonly the latter, are thought by some to undermine reform efforts in philosophy. In this paper, we take a three- pronged approach to these claims. First, we show that the reforms can be motivated quite independently of the implicit bias data, and that many of these reforms are in fact very well suited to dealing with intersectional worries. Next, we show that in fact the empirical concerns about the implicit bias data are not nearly as problematic as some have thought. Finally, we argue that while the intersectional concerns are an immensely valuable criticism of early work on implicit bias, more recent work is starting to address these worries. (shrink)

It is not usually morally permissible to desire the suffering of another person, or to act so as to satisfy this desire; that is, to act with the aim of bringing about suffering. If the retributive emotions, and the retributive responses of which they are a part, are morally permitted or even required, we will need to see what is distinctive about them. One line of argument in this paper is for the conclusion that a retributive desire for the suffering (...) of the wrong-doer, and the aim to bring this about, can (contra recent arguments from Hanna 2008) be morally justified. -/- It has been suggested that by reflecting on the role of the retributive emotions in interpersonal relationships, and the alleged legitimacy of the aim for the suffering of the wrong-doer within them, support can be garnered for retributive practices of punishment by the state (Duff 1986 and 2001, Bennett 2002 and 2003). The conclusion of the second line of argument in the paper is that whilst the retributive responses can permissibly aim at suffering, the way in which this is so in interpersonal relationships cannot provide support for retributive state punishment.

How, if at all, do the findings of social psychology impact upon philosophical analyses of discrimination? In this chapter, I outline key findings from three research programs from psychology – concerning in-group/out-group favoritism; implicit bias; and stereotype threat. I argue that each set of findings presents challenges to how philosophical analyses of group discrimination are formulated, and propose possible revisions to be explored in future work.

The modern abundance and prominence of data has led to the development of “data science” as a new field of enquiry, along with a body of epistemological reflections upon its foundations, methods, and consequences. This article provides a systematic analysis and critical review of significant open problems and debates in the epistemology of data science. We propose a partition of the epistemology of data science into the following five domains: (i) the constitution of data science; (ii) the kind of enquiry (...) that it identifies; (iii) the kinds of knowledge that data science generates; (iv) the nature and epistemological significance of “black box” problems; and (v) the relationship between data science and the philosophy of science more generally.

This article articulates our everyday notion of cooperation. First, I topple an orthodoxy of shared agency theory by arguing that shared intentions to J are neither necessary nor sufficient for J to be cooperative. I refute the necessity claim by providing examples of shared intention-free cooperation (in institutional contexts and beyond). I refute the sufficiency claim by observing that coercion and exploitation need not preclude shared intentions but do preclude cooperation. These arguments, in turn, lead to my positive proposal. People (...) cooperate, I argue, just in case their activities are coordinated in ways that do not undermine any participant’s agency. (shrink)

We explore the relationship between jurisprudential theories pertaining to the nature of law and semantic and metasemantic theories pertaining to the meaning of ‘law’ in the wake of Dworkin’s notorious Semantic Sting argument in Law’s Empire (HUP 1986). Along the way we delineate various aspects of the semantic and metasemantic underpinnings of ‘law’ as an artifact term and advance the general methodological point that jurisprudential inquiry is only negligibly constrained by the findings of semantic and metasemantic inquiry.

The reasonable person standard is used in adjudicating claims of self-defence. In US law, an individual may use defensive force if her beliefs that a threat is imminent and that force is required are beliefs that a reasonable person would have. In English law, it is sufficient that beliefs in imminence and necessity are genuinely held; but the reasonableness of so believing is given an evidential role in establishing the genuineness of the beliefs. There is, of course, much contention over (...) how to spell out when, and in virtue of what, such beliefs are reasonable. In this chapter, we identify some distinctive issues that arise when we consider that implicit racial bias might be implicated in the beliefs in imminence and necessity. Considering two prominent interpretations of the reasonable person standard, we argue that neither is acceptable. On one interpretation, we risk unfairness to the defendant-who may non-culpably harbour bias. On another, the standard embeds racist stereotypes. Whilst there are formulations of the defence that may serve to mitigate these problems, we argue that they cannot be avoided in the presence of racist social structures. (shrink)

In recent years, the concept of “integrity” has been frequently discussed by scholars, and deployed by courts, in the domain of criminal procedure. In this paper, we are particularly concerned with how the concept has been employed in relation to the problem of the admissibility of evidence obtained improperly. In conceptualising and addressing this problem, the advocates of integrity rely on it as a standard of conduct for the criminal justice authorities and as a necessary condition for the state authority (...) to condemn and punish. We raise a series of challenges that need answering before integrity can perform these roles. Our aim is not to show that integrity is useless in normative theorising about the admissibility of evidence, and about the criminal process in general. Rather, it is to give guidance for the elaboration of a theory of integrity that is cogent, coherent, and has useful implications for the process of proof. (shrink)

It is usually appropriate for adults to make significant decisions, such as about what kinds of medical treatment to undergo, for themselves. But sometimes impairments are suffered - either temporary or permanent - which render an individual unable to make such decisions. The Mental Capacity Act 2005 sets out the conditions under which it is appropriate to regard an individual as lacking the capacity to make a particular decision (and when provisions should be made for a decision on their behalf). (...) -/- To what extent does having capacity require the endorsement of certain values? Drawing on Owens et al (2009), I assess the extent to which understanding relevant information and weighing it in coming to a decision requires certain evaluative commitments. With reference to literature on anorexia nervosa and decisions informed by religious beliefs, I argue that it is difficult to avoid the conclusion that the conditions for capacity are value-laden, and that if this is so it is important to open discussion about which patterns of distorted valuing undermine capacity, and why.

This paper analyses the phenomenology and epistemology of chatbots such as ChatGPT and Bard. The computational architecture underpinning these chatbots are large language models (LLMs), which are generative AI (Artificial Intelligence) systems trained on a massive dataset of text extracted from the Web. We conceptualise these LLMs as multifunctional computational cognitive artifacts, used for various cognitive tasks such as translating, summarizing, answering questions, information-seeking, and much more. Phenomenologically, LLMs can be experienced as a “quasi-other”; when that happens, users anthropomorphise them. (...) For most users, current LLMs are black boxes, i.e., for the most part, they lack data transparency and algorithmic transparency. They can, however, be phenomenologically and informationally transparent, in which case there is an interactional flow. Anthropomorphising and interactional flow can, in some users, create an attitude of (unwarranted) trust towards the output LLMs generate. We conclude this paper by drawing on the epistemology of trust and testimony to examine the epistemic implications of these dimensions. Whilst LLMs generally generate accurate responses, we observe two epistemic pitfalls. Ideally, users should be able to match the level of trust that they place in LLMs to the degree that LLMs are trustworthy. However, both their data and algorithmic opacity and their phenomenological and informational transparency can make it difficult for users to calibrate their trust correctly. The effects of these limitations are twofold: users may adopt unwarranted attitudes of trust towards the outputs of LLMs (which is particularly problematic when LLMs hallucinate), and the trustworthiness of LLMs may be undermined.

The debate over persistence currently involves three competing theories—one three-dimensionalist theory called “endurantism” and two four-dimensionalist theories called “perdurantism” and “exdurantism.” This inner debate between the latter two persistence theories is what I aim to clarify, and ultimately, I argue that perdurantism is superior to exdurantism because exdurantism is too extravagant in counting ordinary objects in the world. Extravagant for the reason that objects in their entirety are bound to their momentary stages, and there is practically an interminable number of (...) these stages, which is not reasonable when counting in the ordinary world.

What is involved in acting together with others? Most shared agency theorists endorse the Shared Intention Thesis, i.e., the claim that shared agency necessarily involves shared intentions. This article dissents from this orthodoxy and offers a minimalist account of shared agency—one where parties to shared activities need not form rich webs of interrelated psychological states. My account has two main components: a conceptual analysis of shared agency in terms of the notion of plan, and an explanation of undertheorized agency‐sharing mechanisms. (...) My analysis states that we act together just in case our activities conform to a plan and that plan figures in an explanation of our activities’ joint conformity to it. To sloganize:shared activity is plan‐coordinated activity. Sometimes, plan‐coordination goes by way of shared intentions. However, besides shared intentions, there are at least two additional families of agency‐sharing mechanisms. The first features a central planner who determines the content of a plan and attributes the different parts of that plan to a collection of agents. The second does away with the planner and involves a roughly Darwinian selection of patterns of activity. Both families of mechanisms enable us to act together even in the absence of shared intentions. (shrink)

US Senate is considering legislation designed to immunize small businesses from lawsuits brought by customers alleging to have been infected with COVID-19 while on the premises. The legislation seeks to subsidize reopening small businesses by reducing their vulnerability to liability. I argue that the legislation produces worse public health outcomes than existing liability regimes, obliterates claims to redress supported by corrective justice, and unfairly burdens victims by forcing them to become de facto insurers of their injurers. In the US, where (...) health insurance is inextricably linked with employment, and during the pandemic with the consequent loss of employment, the legislation is cruel in addition to being ineffective, unjust, unfair and inappropriate. Since I first uploaded this manuscript to Philpapers, Senate Republicans have in fact introduced specific legislation that is marginally different than the one I discuss in the manuscript. Instead of offering blanket immunity, the current Republican proposal offers a series of substantial barriers both to filing lawsuits and to securing a successful verdict at trial. I discuss these as an addendum to the main paper. In short, though the changes impact some features of my argument, they do not alter any of the conclusions. The current proposal produces worse public health outcomes than would existing tort regime; it leaves the vast majority of those with legitimate claims to repair in corrective justice without a remedy, when providing the opportunity to secure a remedy for wrongs is in large measure, the essential nature of tort liability. Worse still, it continues to render victims the de facto insurers of those who have wronged them; it imposes the burden of spreading risks on victims who are considerably less efficient risk spreaders than are businesses and hospitals; it constitutes an inappropriate response to the challenge it seeks to address, i.e. subsidizing various sectors of the economy by reducing their overall costs; and given the fact that in the US health insurance is too closely linked to employment, it shifts the costs of the pandemic to those who are most at risk of losing their health insurance, rendering the proposal cruel in addition to inefficient, unjust, unfair and inappropriate. For those interested, I am considering a short op-ed piece assessing the particular legislative proposal. If I follow through I will let the readership know where that can be found. (shrink)

Effective altruism sounds so innocuous—who could possibly be opposed to doing good more effectively? Yet it has inspired significant backlash in recent years. This paper addresses some common misconceptions and argues that the core “beneficentric” ideas of effective altruism are both excellent and widely neglected. Reasonable people may disagree on details of implementation, but all should share the basic goals or values underlying effective altruism.

Some of the most important developments of symbolic logic took place in the 1920s. Foremost among them are the distinction between syntax and semantics and the formulation of questions of completeness and decidability of logical systems. David Hilbert and his students played a very important part in these developments. Their contributions can be traced to unpublished lecture notes and other manuscripts by Hilbert and Bernays dating to the period 1917-1923. The aim of this paper is to describe these results, focussing (...) primarily on propositional logic, and to put them in their historical context. It is argued that truth-value semantics, syntactic ("Post-") and semantic completeness, decidability, and other results were first obtained by Hilbert and Bernays in 1918, and that Bernays's role in their discovery and the subsequent development of mathematical logic is much greater than has so far been acknowledged.

In Mind and World, John McDowell argues against the view that perceptual representation is non-conceptual. The central worry is that this view cannot offer any reasonable account of how perception bears rationally upon belief. I argue that this worry, though sensible, can be met, if we are clear that perceptual representation is, though non-conceptual, still in some sense 'assertoric': Perception, like belief, represents things as being thus and so.

This paper draws on the 'Fitting Attitudes' analysis of value to argue that we should take the concept of fittingness (rather than value) as our normative primitive. I will argue that the fittingness framework enhances the clarity and expressive power of our normative theorising. Along the way, we will see how the fittingness framework illuminates our understanding of various moral theories, and why it casts doubt on the Global Consequentialist idea that acts and (say) eye colours are normatively on a (...) par. We will see why even consequentialists, in taking rightness to be in some sense determined by goodness, should not think that rightness is conceptually reducible to goodness. Finally, I will use the fittingness framework to explicate the distinction between consequentialist and deontological theories, with particular attention to the contentious case of Rule Consequentialism.

What we value, like, endorse, want, and prefer changes over the course of our lives. Richard Pettigrew presents a theory of rational decision making for agents who recognise that their values will change over time and whose decisions will affect those future times.

Many proponents of the Harm Principle seem to implicitly assume that the principle is compatible with permitting the free exchange of goods and services, even if such exchanges generate so-called market harms. I argue that, as a result, proponents of the Harm Principle face a dilemma: either the Harm Principle’s domain cannot include a large number of non-market harm cases or market harms must be treated on par with non-market harms. I then go on to discuss three alternative arguments defending (...) the status of market harms as exceptions to the Harm Principle and discuss why these arguments also fail. (shrink)

Angell's logic of analytic containment AC has been shown to be characterized by a 9-valued matrix NC by Ferguson, and by a 16-valued matrix by Fine. We show that the former is the image of a surjective homomorphism from the latter, i.e., an epimorphic image. The epimorphism was found with the help of MUltlog, which also provides a tableau calculus for NC extended by quantifiers that generalize conjunction and disjunction.

It is common for religiously motivated actions to be specially protected by law. Many legal theorists have asked why: what makes religion special? What makes it worthy of toleration over and above other non-religious deeply held convictions? The answer I put forward is that religions’ alleged afterlife consequences call for a principle of toleration that warrants special legal treatment. Under a Rawlsian principle of toleration, it is reasonable for those in the original position to opt for principles of justice that (...) accommodate actions with alleged afterlife consequences. And, under a utilitarian principle of toleration, a greater psychological harm is eased by such accommodations. Additionally, this alleged afterlife consequence is found in most of the religions that are thought to warrant some level of special toleration—not only do the Abrahamic religions have alleged afterlife consequences, but many eastern religions do as well, e.g. reincarnation.

There is too much that we do not know about COVID-19. The longer we take to find it out, the more lives will be lost. In this paper, we will defend a principle of risk parity: if it is permissible to expose some members of society (e.g. health workers or the economically vulnerable) to a certain level of ex ante risk in order to minimize overall harm from the virus, then it is permissible to expose fully informed volunteers to a (...) comparable level of risk in the context of promising research into the virus. We apply this principle to three examples of risky research: skipping animal trials for promising treatments, human challenge trials to speed up vaccine development, and low-dose controlled infection or “variolation.” We conclude that if volunteers, fully informed about the risks, are willing to help fight the pandemic by aiding promising research, there are strong moral reasons to gratefully accept their help. To refuse it would implicitly subject others to still graver risks. (shrink)

This paper applies a virtue epistemology approach to using the Internet, as to improve our information-seeking behaviours. Virtue epistemology focusses on the cognitive character of agents and is less concerned with the nature of truth and epistemic justification as compared to traditional analytic epistemology. Due to this focus on cognitive character and agency, it is a fruitful but underexplored approach to using the Internet in an epistemically desirable way. Thus, the central question in this paper is: How to use the (...) Internet in an epistemically virtuous way? Using the work of Jason Baehr, it starts by outlining nine intellectual or epistemic virtues: curiosity, intellectual autonomy, intellectual humility, attentiveness, intellectual carefulness, intellectual thoroughness, open-mindedness, intellectual courage and intellectual tenacity. It then explores how we should deploy these virtues and avoid the corresponding vices when interacting with the Internet, particularly search engines. Whilst an epistemically virtuous use of the Internet will not guarantee that one will acquire true beliefs, understanding or even knowledge, it will strongly improve one’s information-seeking behaviours. The paper ends with arguing that teaching and assessing online intellectual virtues should be part of school and university curricula, perhaps embedded in critical thinking courses, or even better, as individual units.

Satisficing Consequentialism is often rejected as hopeless. Perhaps its greatest problem is that it risks condoning the gratuitous prevention of goodness above the baseline of what qualifies as "good enough". I propose a radical new willpower-based version of the view that avoids this problem, and that better fits with the motivation of avoiding an excessively demanding conception of morality. I further demonstrate how, by drawing on the resources of an independent theory of blameworthiness, we may obtain a principled specification of (...) what counts as "good enough". (shrink)

In this paper, we seek a reliabilist account of justified credence. Reliabilism about justified beliefs comes in two varieties: process reliabilism (Goldman, 1979, 2008) and indicator reliabilism (Alston, 1988, 2005). Existing accounts of reliabilism about justified credence comes in the same two varieties: Jeff Dunn (2015) proposes a version of process reliabilism, while Weng Hong Tang (2016) offers a version of indicator reliabilism. As we will see, both face the same objection. If they are right about what justification is, it (...) is mysterious why we care about justification, for neither of the accounts explains how justification is connected to anything of epistemic value. We will call this the Connection Problem. I begin by describing Dunn’s process reliabilism and Tang’s indicator reliabilism. I argue that, understood correctly, they are, in fact, extensionally equivalent. That is, Dunn and Tang reach the top of the same mountain, albeit by different routes. However, I argue that both face the Connection Problem. In response, I offer my own version of reliabilism, which is both process and indicator, and I argue that it solves that problem. Furthermore, I show that it is also extensionally equivalent to Dunn’s reliabilism and Tang’s. Thus, I reach the top of the same mountain as well. (shrink)

According to certain normative theories in epistemology, rationality requires us to be logically omniscient. Yet this prescription clashes with our ordinary judgments of rationality. How should we resolve this tension? In this paper, I focus particularly on the logical omniscience requirement in Bayesian epistemology. Building on a key insight by Hacking :311–325, 1967), I develop a version of Bayesianism that permits logical ignorance. This includes: an account of the synchronic norms that govern a logically ignorant individual at any given time; (...) an account of how we reduce our logical ignorance by learning logical facts and how we should update our credences in response to such evidence; and an account of when logical ignorance is irrational and when it isn’t. At the end, I explain why the requirement of logical omniscience remains true of ideal agents with no computational, processing, or storage limitations. (shrink)

Utilitarianism is often rejected on the grounds that it fails to respect the separateness of persons, instead treating people as mere “receptacles of value”. I develop several different versions of this objection, and argue that, despite their prima facie plausibility, they are all mistaken. Although there are crude forms of utilitarianism that run afoul of these objections, I advance a new form of the view—‘token-pluralistic utilitarianism’—that does not.

In The Boundary Stones of Thought, Rumfitt defends classical logic against challenges from intuitionistic mathematics and vagueness, using a semantics of pre-topologies on possibilities, and a topological semantics on predicates, respectively. These semantics are suggestive but the characterizations of negation face difficulties that may undermine their usefulness in Rumfitt’s project.

Disagreement is common: even informed, intelligent, and generally reasonable people often come to different conclusions when confronted with what seems to be the same evidence. Can the competing conclusions be reasonable? If not, what can we reasonably think about the situation? This volume examines the epistemology of disagreement. Philosophical questions about disagreement arise in various areas, notably politics, ethics, aesthetics, and the philosophy of religion: but this will be the first book focusing on the general epistemic issues arising from informed (...) disagreement. Ten leading philosophers offer specially written essays which together will offer a starting-point for future work on this topic. (shrink)

Conditionalization is one of the central norms of Bayesian epistemology. But there are a number of competing formulations, and a number of arguments that purport to establish it. In this paper, I explore which formulations of the norm are supported by which arguments. In their standard formulations, each of the arguments I consider here depends on the same assumption, which I call Deterministic Updating. I will investigate whether it is possible to amend these arguments so that they no longer depend (...) on it. As I show, whether this is possible depends on the formulation of the norm under consideration. (shrink)

Dembroff and Wodak (2018, 2021) argue that we have a duty to use gender-neutral pronouns, but do not extend this argument to all other aspects of our language. We evaluate the extent to which gender neutral language is desirable in the context of parental leave schemes, taking as a case study the parental leave schemes found at a Higher Education Institution in the UK. We argue that the considerations Dembroff and Wodak (2018, 2021) take to speak against gender specific pronouns (...) and some other gender specific aspects of language also strongly speak against gender specific language in the context of parental leave policies. As a project in non-ideal theory, we argue against the framing of existing policies which refer to ‘maternity’ and ‘paternity’ leave, and for moving to the language of ‘parental’ or ‘family’ leave. The fact that the majority of those giving birth are women does not provide decisive reasons for framing policies in gender-specific terms. Moreover, we argue that given the welcome move to facilitate shared parental leave, any concerns for gender equity, and equity for carers, are better served by requesting demographic information for monitoring purposes, rather than by policies that refer to gender specific parenting roles. -/- .

Critics have often misunderstood the higher-order theory (HOT) of consciousness. Here we clarify its position on several issues, and distinguish it from other views such as the global The higher-order theory (HOT) of consciousness has often been misunderstood by critics. Here we clarify its position on several issues, and distinguish it from other views such as the global workspace theory (GWT) and early sensory models (e.g. first-order local recurrency theories). For example, HOT has been criticized for over-intellectualizing consciousness. We show (...) that while higher-order states are cognitively assembled, the requirements are actually considerably less than often presumed. In this sense HOT may be viewed as an intermediate position between GWT and early sensory views. Also, we clarify that most proponents of HOT do not stipulate consciousness as equivalent to metacognition or confidence. Further, compared to other existing theories, HOT can arguably account better for complex everyday experiences, such as of emotions and episodic memories. This makes HOT particularly useful as a framework for conceptualizing pathological mental states. (shrink)
