Five experiments investigated the role of spatial connectedness between a pair of objects presented in the change detection task for the actual capacity of visual working memory (VWM) in healthy young adults (total N = 405). Three experiments yielded a surprising nonlinear relationship between the proportion of pair-wise connected objects and capacity, with the highest capacity observed for homogenous displays, when either all objects were connected or disjointed. A drop in capacity, ranging from an average of a quarter of an (...) object out of three objects maintained in VWM, was noted when only some objects were connected while others were disjointed. As indicated by another two experiments, this effect was specific to double-feature encoding, but disappeared when single visual features had to be memorized. No existing theoretical model of VWM can directly explain this novel effect. Overall, the nonlinear effect of spatial connectedness implies that representations in VWM possess hierarchical structure defined by wholes, parts, features, and their relations, and the heterogeneity of such a structure hinders VWM performance, while homogeneity facilitates it.

This is a reply to de Sousa's 'Emotional Truth', in which he argues that emotions can be objective, as propositional truths are. I say that it is better to distinguish between truth and accuracy, and agree with de Sousa to the extent of arguing that emotions can be more or less accurate, that is, based on the facts as they are.

Models as Make-Believe offers a new approach to scientific modelling by looking to an unlikely source of inspiration: the dolls and toy trucks of children's games of make-believe.

Support for the biological concept of race declined slowly but steadily during the second half of the twentieth century. However, debate about the validity of the race concept has recently been reignited. Genetic-clustering studies have shown that despite the small proportion of genetic variation separating continental populations, it is possible to assign some individuals to their continents of origin, based on genetic data alone. Race naturalists have interpreted these studies as empirically confirming the existence of human subspecies, and by extension (...) biological races. However, the new racial naturalism is not convincing. The continental clusters appealed to by race naturalists are arbitrary and superficial groupings, which should not be elevated to subspecies status. Moreover, the criteria applied to humans are not consistent with those used to define subspecies in nonhuman animals, and no rationale has been given for this differential treatment. (shrink)

I develop several new arguments against claims about "cognitive phenomenology" and its alleged role in grounding thought content. My arguments concern "absent cognitive qualia cases", "altered cognitive qualia cases", and "disembodied cognitive qualia cases". However, at the end, I sketch a positive theory of the role of phenomenology in grounding content, drawing on David Lewis's work on intentionality. I suggest that within Lewis's theory the subject's total evidence plays the central role in fixing mental content and ruling out deviant interpretations. (...) However I point out a huge unnoticed problem, the problem of evidence: Lewis really has no theory of sensory content and hence no theory of what fixes evidence. I suggest a way of plugging this hole in Lewis's theory. On the resulting theory, which I call " phenomenal functionalism", there is a sense in which sensory phenomenology is the source of all determinate intentionality. Phenomenal functionalism has similarities to the theories of Chalmers and Schwitzgebel. (shrink)

Recent progress in artificial intelligence (AI) has drawn attention to the technology’s transformative potential, including what some see as its prospects for causing large-scale harm. We review two influential arguments purporting to show how AI could pose catastrophic risks. The first argument — the Problem of Power-Seeking — claims that, under certain assumptions, advanced AI systems are likely to engage in dangerous power-seeking behavior in pursuit of their goals. We review reasons for thinking that AI systems might seek power, that (...) they might obtain it, that this could lead to catastrophe, and that we might build and deploy such systems anyway. The second argument claims that the development of human-level AI will unlock rapid further progress, culminating in AI systems far more capable than any human — this is the Singularity Hypothesis. Power-seeking behavior on the part of such systems might be particularly dangerous. We discuss a variety of objections to both arguments and conclude by assessing the state of the debate. (shrink)

In “The Meta-Problem of Consciousness”, David Chalmers briefly raises a problem about how the connection between consciousness and our verbal and other behavior appears “lucky”. I raise a counterexample to Chalmers’s formulation of the problem. Then I develop an alternative formulation. Finally, I consider some responses, including illusionism about consciousness.

Orthodox decision theory gives no advice to agents who hold two goods to be incommensurate in value because such agents will have incomplete preferences. According to standard treatments, rationality requires complete preferences, so such agents are irrational. Experience shows, however, that incomplete preferences are ubiquitous in ordinary life. In this paper, we aim to do two things: (1) show that there is a good case for revising decision theory so as to allow it to apply non-vacuously to agents with incomplete (...) preferences, and (2) to identify one substantive criterion that any such non-standard decision theory must obey. Our criterion, Competitiveness, is a weaker version of a dominance principle. Despite its modesty, Competitiveness is incompatible with prospectism, a recently developed decision theory for agents with incomplete preferences. We spend the final part of the paper showing why Competitiveness should be retained, and prospectism rejected. (shrink)

In several recent contributions to the growing literature on slurs, Hedger draws upon Kaplan's distinction between descriptive and expressive content to argue that slurs are expressions with purely expressive content. The distinction between descriptive and expressive content and the view that slurs are expressions with purely expressive content has been widely acknowledged in prior work, and Hedger aims to contribute to this tradition of scholarship by offering novel arguments in support of his "pure expressivist" account of slurs. But the account (...) that PE offers is explanatorily inadequate, resting on suspect a priori intuitions which also commit one to denying many basic facts about slurs, such as that slurs largely display systematic differential application and that slurs can be used non-offensively between in-group speakers. In this article I provide clear reasons for rejecting PE, arguing particularly against Hedger as one of PE’s most explicit and recent proponents. In showing that PE is inadequate in at least 11 ways, I argue in favor of a mixed or hybrid approach. (shrink)

This article provides an original account of slurs and how they may be differentially used by in-group and out-group speakers. Slurs are first distinguished from other terms and their role in social interaction is discussed. A new distinction is introduced between three different uses of slurs : the paradigmatic derogatory use, non-paradigmatic derogatory use, and non-paradigmatic non-derogatory use. I then account for their literal meaning and explain how a family-resemblance conception of category membership can clarify our understanding of the various (...) natural-language uses of slurs, -. The focus is restricted primarily to race-based and sex-based slurs used in the context of English speakers, and the article concludes with desiderata to be met by any subsequent analyses of slurs.

This paper begins with a discussion the role of less-than-admirable epistemic emotions in our respectable, indeed admirable inquiries: nosiness, obsessiveness, wishful thinking, denial, partisanship. The explanation for their desirable effect is Mandevillian: because of the division of epistemic labour individual epistemic vices can lead to shared knowledge. In fact it is sometimes essential to it.

The UNESCO Statements on Race of the early 1950s are understood to have marked a consensus amongst natural scientists and social scientists that ‘race’ is a social construct. Human biological diversity was shown to be predominantly clinal, or gradual, not discreet, and clustered, as racial naturalism implied. From the seventies social constructionists added that the vast majority of human genetic diversity resides within any given racialised group. While social constructionism about race became the majority consensus view on the topic, social (...) constructionism has always had its critics. Sesardic (2010) has compiled these criticisms into one of the strongest defences of racial naturalism in recent times. In this paper I argue that Sesardic equivocates between two versions of racial naturalism: a weak version and a strong version. As I shall argue, the strong version is not supported by the relevant science. The weak version, on the other hand, does not contrast properly with what social constructionists think about ‘race’. By leaning on this weak view Sesardic’s racial naturalism intermittently gains an appearance of plausibility, but this view is too weak to revive racial naturalism. As Sesardic demonstrates, there are new arguments for racial naturalism post-Human Genome Diversity Project. The positive message behind my critique is how to be a social constructionist about race in the post-genomic era. (shrink)

Here I explore a new line of evidence for belief–credence dualism, the thesis that beliefs and credences are distinct and equally fundamental types of mental states. Despite considerable recent disagreement over this thesis, little attention has been paid in philosophy to differences in how our mindreading systems represent the beliefs and credences of others. Fascinatingly, the systems we rely on to accurately and efficiently track others’ mental states appear to function like belief–credence dualists: Credence is tracked like an emotional state, (...) composed of both representational and affective content, whereas belief is tracked like a bare representational state with no affective component. I argue on a preliminary basis that, in this particular case, the mechanics of mentalizing likely pick out a genuine affective dimension to credence that is absent for belief, further strengthening the converging case for belief–credence dualism.

Neven Sesardic has recently defended his arguments in favour of racial naturalism—the view that race is a valid biological category—in response to my criticism of his work. While Sesardic claims that a strong version of racial naturalism can survive critique, he has in fact weakened his position considerably. He concedes that conventional racial taxonomy is arbitrary and he no longer identifies ‘races’ as human subspecies. Sesardic now relies almost entirely on Theodosius Dobzhansky’s notion of race-as-population. This weak approach to ‘race’—according (...) to which all genetic difference between populations is ‘racial’ and ‘the races’ are simply the populations we choose to call races—survived its early critiques. As it is being mobilised to support racial naturalism once more, we need to continue the debate about whether we should weaken the concept of race to mean ‘population’, or abandon it as a failed biological category. I argue that Sesardic’s case for racial naturalism is only supported by his continued mischaracterisation of anti-realism about biological race and his appeal to Dobzhansky’s authority. Rather than deflating the meaning of ‘race’, it should be eliminated from our biological ontology. (shrink)

It would be good to have a Bayesian decision theory that assesses our decisions and thinking according to everyday standards of rationality — standards that do not require logical omniscience (Garber 1983, Hacking 1967). To that end we develop a “fragmented” decision theory in which a single state of mind is represented by a family of credence functions, each associated with a distinct choice condition (Lewis 1982, Stalnaker 1984). The theory imposes a local coherence assumption guaranteeing that as an agent's (...) attention shifts, successive batches of "obvious" logical information become available to her. A rule of expected utility maximization can then be applied to the decision of what to attend to next during a train of thought. On the resulting theory, rationality requires ordinary agents to be logically competent and to often engage in trains of thought that increase the unification of their states of mind. But rationality does not require ordinary agents to be logically omniscient. (shrink)

I assess Churchland's views on folk psychology and conceptual thinking, with particular emphasis on the connection between these topics.

There seem to be many kinds of moral duties. We should keep our promises; we should pay our debts of gratitude; we should compensate those we’ve wronged; we should avoid doing or intending harm; we should help those in need. These constitute, some worry, an unconnected heap of duties: the realm of commonsense morality is a disorganized mess. In this paper, we outline a strategy for unifying commonsense moral duties. We argue that they can be understood in terms of contact (...) with value. You are in contact with a value when you are manifest in it or when it is manifest in you. You have reason to get in contact with the good and avoid contact with evil. And when you’re in contact with a value, the weight of the reasons it grounds are amplified for you. These ideas, we argue, can bring order to the chaos of commonsense morality. (shrink)

I consider Glimcher's claim to have given an account of mental functioning that is at once neurological and decision-theoretical. I am skeptical, but remark on some good ideas of Glimcher's.

Many traditional attempts to show that nonhuman animals are deserving of moral consideration have taken the form of an argument by analogy. However, arguments of this kind have had notable weaknesses and, in particular, have not been able to convince two kinds of skeptics. One of the most important weaknesses of these arguments is that they fail to provide theoretical justifications for why particular physiological similarities should be considered relevant. This paper examines recent empirical research on pain and, in particular, (...) explores the implications of the dissociation between the sensory and the affective pain pathways. It is argued that these results show that the belief that nonhuman animals experience pain in a morally relevant way is reasonable, though not certain. It is further argued that the proposal to explore the relationship between consciousness and various forms of learning challenges the aforementioned skeptics to provide more physiological details for their claims that nonhuman mammals are probably not conscious.

Proponents of epistocracy worry that high levels of voter ignorance can harm democracies. To combat such ignorance, they recommend allocating comparatively more political power to more politically knowledgeable citizens. In response, some recent critics of epistocracy contend that epistocratic institutions risk causing even more harm, since much evidence from political psychology indicates that more politically knowledgeable citizens are typically more biased, less open-minded, and more prone to motivated reasoning about political matters than their less knowledgeable counterparts. If so, perhaps epistocratic (...) institutions will perform worse epistemically than corresponding democratic institutions. Call this 'the problem of epistocratic irrationality'. This paper argues that the problem of epistocratic irrationality can be overcome. First, I argue that critics of epistocracy have overlooked several complications regarding the psychological data they claim shows that more knowledgeable citizens are less politically rational. Second, I argue that appropriately designed epistocratic institutions could overcome the problem of epistocratic irrationality even if such critics have interpreted the data correctly. I first explore whether refined selection mechanisms could allow epistocrats to avoid empowering less rational citizens, before assessing the prospects of implementing only those epistocratic institutions with a solid track record of reliable performance.

Some philosophers argue that martial arts training is maladaptive, contributes to psychological illness, and provides a social harm, whereas others argue that martial arts training is adaptive, contributes to psychological wellness, and provides a social benefit. This debate is important to scholars and the general public since beliefs about martial arts training can have a real impact on how we evaluate martial artists for job opportunities and career advancement, and in general, how we treat martial artists from different cultures in (...) our communities. This debate is also important for children and adults that have considered enrolling in martial arts training programs but remain uncertain about potential outcomes of training due to the lack of research in this area. This article therefore contributes to the literature on martial arts by (1) outlining a framework that characterizes psychological well-being in terms of five elements, (2) discussing how results from empirical research support the hypothesis that Muay Thai training can contribute to psychological well-being by contributing to all five component elements, (3) discussing the psychological benefits of martial arts training from the perspective of an Everlast Master Instructor, and (4) discussing how martial arts training involves the cultivation of combat-relevant affordances.

In “Radical Interpretation” (1974), David Lewis asked: by what constraints, and to what extent, do the non-intentional, physical facts about Karl determine the intentional facts about him? There are two popular approaches: the reductive externalist program and the phenomenal intentionality program. I argue against both approaches. Then I sketch an alternative multistage account incorporating ideas from both camps. If we start with Karl's conscious experiences, we can appeal to Lewisian ideas to explain his other intentional states. This account develops the (...) multistage Lewisian approach presented at the end of my earlier "Does Phenomenology Ground Mental Content?" (2013). (shrink)

Politics is full of people who don’t care about the facts. Still, while not caring about the facts, they are often concerned to present themselves as caring about them. Politics, in other words, is full of bullshitters. But why? In this paper I develop an incentives-based analysis of bullshit in politics, arguing that it is often a rational response to the incentives facing different groups of agents. In a slogan: bullshit in politics pays, sometimes literally. After first outlining an account (...) of bullshit (Section 1), I discuss the incentives driving three different groups of agents to bullshit: politicians, the media, and voters (Section 2). I then examine several existing proposals to combat bullshit in politics, arguing that each will fail because they ignore the relevant underlying incentives (Section 3). I conclude somewhat pessimistically that a certain amount of bullshit in politics is inevitable (Section 4). (shrink)

In 1990 Robert Lickliter and Thomas Berry identified the phylogeny fallacy, an empirically untenable dichotomy between proximate and evolutionary causation, which locates proximate causes in the decoding of ‘ genetic programs’, and evolutionary causes in the historical events that shaped these programs. More recently, Lickliter and Hunter Honeycutt argued that Evolutionary Psychologists commit this fallacy, and they proposed an alternative research program for evolutionary psychology. For these authors the phylogeny fallacy is the proximate/evolutionary distinction itself, which they argue constitutes a (...) misunderstanding of development, and its role in the evolutionary process. In this article I argue that the phylogeny fallacy should be relocated to an error of reasoning that this causal framework sustains: the conflation of proximate and evolutionary explanation. Having identified this empirically neutral form of the phylogeny fallacy, I identify its mirror image, the ontogeny fallacy. Through the lens of these fallacies I attempt to solve several outstanding problems in the debate that ensued from Lickliter and Honeycutt’s provocative article. (shrink)

Unlike identity physicalism, ground physicalism does not achieve the physicalist dream. It faces the T-shirt problem for ground physicalism (Pautz 2014; Schaffer this volume; Rubenstein ms). In the case of insentient nature, it may be able to get by with small handful of very general ground laws to explain the emergence of nonfundamental objects and properties – for example, a few “principle of plenitude”. But I argue that for the case consciousness it will require a separate huge raft of special, (...) anomalous psychophysical ground laws. So it is just as complex and nonuniform as dualism. (shrink)

Voters have many motivations. Some vote on the issues. They vote for a candidate because they share that candidate's policy positions. Some vote on performance. They vote for a candidate because they think that candidate will produce the best outcomes in office. Some vote on group identities. They vote for a candidate because that candidate is connected to their social group. This paper is about these motivations. I address three questions. First, which of these motivations, were it widespread, would be (...) best for intrinsic democratic values? Second, how do the motivations of actual American voters affect the value of American democracy? Third, what motivations should individual American voters have? I argue that widespread issue voting would be best, followed by performance voting, followed by group voting. I argue that American voters do not much contribute to the value of American democracy. Their behavior makes it hard to achieve many democratic values. Finally, I argue that, were America an ideal democracy, American voters would have reason to vote on the issues. But, in their non-ideal democracy, American voters merely have reason to avoid voting on privileged group identities. (shrink)

Looking to Scripture through the eyes of contemporary medical experience, I analyze the meaning of the criteria used for determining death, specifically in the light of Jesus’ final moments and the resurrection of the Shunammite’s son in 2 Kings, chapter 4. I argue that four theses are consistent with, and informed by, these passages that can help guide Christian belief and decision-making about how death is determined in the clinical context: (1) death is neither permanent nor irreversible; (2) something like (...) the “brain dead” state is, at best, a confounding state that requires one to “pace and pray” or let go; (3) that the case for determining death by neurologic criteria depends on the “working togetherness” of the body's parts for the sake of impacting its environment; and (4) that the practice of neurologically-based death determination is a response to the problem of disaggregation of the human form into its organ systems that modern critical care medicine makes possible. I end with advice about how Christians might approach the debates over the law and practice even if they cannot come to a consensus. (shrink)

The extended mind hypothesis (EMH) is the claim that the mind can and does extend beyond the human body. Adams and Aizawa (A&A) contend that arguments for EMH commit a ‘coupling constitution fallacy’. We deny that the master argument for EMH commits such a fallacy. But we think that there is an important question lurking behind A&A's allegation: under what conditions is cognition spread across a tightly coupled system? Building on some suggestions from Haugeland, we contend that the system must (...) exhibit a distinctive sort of semantic activity, semantic activity that the system as a whole takes responsibility for.

In “The Semantics of Racial Slurs,” an article recently published in Linguistic and Philosophical Investigations, Hedger draws upon Kaplan’s distinction between descriptive and expressive content to argue that slurs are expressions with purely expressive content. Here I review the key considerations presented by Hedger in support of his purely expressive account of slurs and provide clear reasons for why it must ultimately be rejected. After reviewing the key cases Hedger offers for consideration in support of his view that slurs are (...) expressions with purely expressive content, this article provides a critical evaluation of these cases, pointing out at least 13 ways in which his purely expressive analysis of slurs fails. In considering the 13 ways in which the purely expressive analysis of slurs remains inadequate, this article concludes with the suggestion that an adequate account of slurs will ultimately involve not only an expressive aspect but a descriptive aspect also.

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 paper defends the concept of racialization against its critics. As the concept has become increasingly popular, questions about its meaning and value have been raised, and a backlash against its use has occurred. I argue that when “racialization” is properly understood, criticisms of the concept are unsuccessful. I defend a definition of racialization and identify its companion concept, “racialized group.” Racialization is often used as a synonym for “racial formation.” I argue that this is a mistake. Racial formation theory (...) is committed to racial ontology, but racialization is best understood as the process through which racialized – rather than racial – groups are formed. “Racialization” plays a unique role in the conceptual landscape, and it is a key concept for race eliminativists and anti-realists about race.

I discuss the possibility that there is no intrinsic unity to the capacities which are bundled under the label "folk psychology". Cooperative skills, attributional skills, and predictive skills may be scattered as parts of other non--psychological capacities. I discuss how some forms of social life bring these different skills together. I end with some remarks on how abilities that are not unified in their essential mechanisms may still form a rough practical unity. (Remark: the paper is conjectural. It describes a (...) possibility to take seriously rather than a conclusion of which I am convinced.). (shrink)

In order to predict and explain behavior, one cannot specify the mental state of an agent merely by saying what information she possesses. Instead one must specify what information is available to an agent relative to various purposes. Specifying mental states in this way allows us to accommodate cases of imperfect recall, cognitive accomplishments involved in logical deduction, the mental states of confused or fragmented subjects, and the difference between propositional knowledge and know-how .

Slurs possess interesting linguistic properties and so have recently attracted the attention of linguists and philosophers of language. For instance the racial slur "nigger" is explosively derogatory, enough so that just hearing it mentioned can leave one feeling as if they have been made complicit in a morally atrocious act.. Indeed, the very taboo nature of these words makes discussion of them typically prohibited or frowned upon. Although it is true that the utterance of slurs is illegitimate and derogatory in (...) most contexts, sufficient evidence suggests that slurs are not always or exclusively used to derogate. In fact, slurs are frequently picked up and appropriated by the very in-group members that the slur was originally intended to target. This might be done, for instance, as a means for like speakers to strengthen in-group solidarity. So an investigation into the meaning and use of slurs can give us crucial insight into how words can be used with such derogatory impact, and how they can be turned around and appropriated as vehicles of rapport in certain contexts among in-group speakers. In this essay I will argue that slurs are best characterized as being of a mixed descriptive/expressive type. Next, I will review the most influential accounts of slurs offered thus far, explain their shortcomings, then provide a new analysis of slurs and explain in what ways it is superior to others. Finally, I suggest that a family-resemblance conception of category membership can help us achieve a clearer understanding of the various ways in which slurs, for better or worse, are actually put to use in natural language discourse.

We take it that conscious acquaintance has great epistemic value. I develop a new problem for reductive physicalism concerning the epistemic value of acquaintance. The problem concerns "multiple candidate cases". (This develops a theme of my paper *The Significance Argument for the Irreducibility of Consciousness", Philosophical Perspectives 2017.).

People’s beliefs about normality play an important role in many aspects of cognition and life (e.g., causal cognition, linguistic semantics, cooperative behavior). But how do people determine what sorts of things are normal in the first place? Past research has studied both people’s representations of statistical norms (e.g., the average) and their representations of prescriptive norms (e.g., the ideal). Four studies suggest that people’s notion of normality incorporates both of these types of norms. In particular, people’s representations of what is (...) normal were found to be influenced both by what they believed to be descriptively average and by what they believed to be prescriptively ideal. This is shown across three domains: people’s use of the word ‘‘normal” (Study 1), their use of gradable adjectives (Study 2), and their judgments of concept prototypicality (Study 3). A final study investigated the learning of normality for a novel category, showing that people actively combine statistical and prescriptive information they have learned into an undifferentiated notion of what is normal (Study 4). Taken together, these findings may help to explain how moral norms impact the acquisition of normality and, conversely, how normality impacts the acquisition of moral norms. (shrink)

Francisco Gil-White argues that the ubiquity of racialism—the view that so-called races have biological essences—can be explained as a by-product of a shared mental module dedicated to ethnic cognition. Gil-White’s theory has been endorsed, with some revisions, by Edouard Machery and Luc Faucher. In this skeptical response I argue that our developmental environments contain a wealth, rather than a poverty of racialist stimulus, rendering a nativist explanation of racialism redundant. I also argue that we should not theorize racialism in isolation (...) from racism, as value judgments may play a role in essentialist thinking about the ‘other’. (shrink)

The similarity view of scientific representation has recently been subjected to strong criticism. Much of this criticism has been directed against a ?naive? similarity account, which tries to explain representation solely in terms of similarity between scientific models and the world. This article examines the more sophisticated account offered by the similarity view's leading proponent, Ronald Giere. In contrast to the naive account, Giere's account appeals to the role played by the scientists using a scientific model. A similar move is (...) often made by defenders of resemblance theories of depiction, who invoke the role played by the artist, or by the viewers of a painting. In this article I look to debates over depiction to assess the difficulties facing those who wish to defend the similarity view of scientific representation. I then turn to examine Giere's account. Ultimately, I argue, this account is unsuccessful: while appealing to the role of scientists offers a promising way to defend the similarity view, Giere's own account does not capture what it is that scientists do when they use a model to represent the world.

Exclusionary defeat is Joseph Raz’s proposal for understanding the more complex, layered structure of practical reasoning. Exclusionary reasons are widely appealed to in legal theory and consistently arise in many other areas of philosophy. They have also been subject to a variety of challenges. I propose a new account of exclusionary reasons based on their justificatory role, rejecting Raz’s motivational account and especially contrasting exclusion with undercutting defeat. I explain the appeal and coherence of exclusionary reasons by appeal to commonsense (...) value pluralism and the intermediate space of public policies, social roles, and organizations. We often want our choices to have a certain character or instantiate a certain value and in order to do so, that choice can only be based on a restricted set of reasons. Exclusion explains how pro tanto practical reasons can be disqualified from counting towards a choice of a particular kind without being outweighed or undercut. (shrink)

Human rights have a rich life in the world around us. Political rhetoric pays tribute to them, or scorns them. Citizens and activists strive for them. The law enshrines them. And they live inside us too. For many of us, human rights form part of how we understand the world and what must (or must not) be done within it. -/- The ubiquity of human rights raises questions for the philosopher. If we want to understand these rights, where do we (...) look? As a set of moral norms, it is tempting to think they can be grasped strictly from the armchair, say, by appeal to moral intuition. But what, if anything, can that kind of inquiry tell us about the human rights of contemporary politics, law, and civil society — that is, human rights as we ordinarily know them? -/- This volume brings together a distinguished, interdisciplinary group of scholars to address philosophical questions raised by the many facets of human rights: moral, legal, political, and historical. Its original chapters, each accompanied by a critical commentary, explore topics including: the purpose and methods of a philosophical theory of human rights; the "Orthodox-Political" debate; the relevance of history to philosophy; the relationship between human rights morality and law; and the value of political critiques of human rights.

Many contemporary democratic theorists are democratic egalitarians. They think that the distinctive value of democracy lies in equality. Yet this position faces a serious problem. All contemporary democracies are representative democracies. Such democracies are highly unequal: representatives have much more power than do ordinary citizens. So, it seems that democratic egalitarians must condemn representative democracies. In this paper, I present a solution to this problem. My solution invokes popular control. If representatives are under popular control, then their extra power is (...) not objectionable. Unfortunately, so I argue, in the United States representatives are under loose popular control.

The three target articles constitute a powerful and persuasive call for actively anti-racist bioethics and biomedicine. All three articles reject race as a biological category. Nevertheless, they share a common commitment to racial classification. At one point, Ruqaiijah Yearby writes that “social race, like biological race, is an illusion created to establish racial hierarchy,” but mostly she writes about “races” as though they were not an illusion, but a reality. In this commentary I critique the racial realism of the target (...) articles. I argue that the biomedical fight against racism is best served by a form of anti-realist reconstructionism about race, which says that there are no races, only racialized groups—groups misunderstood to be races. Note that I do not defend the color blindness that Clarence H. Braddock (2020) persuasively rejects. Because of the role of skin color in racialization and racism, color blindness is a misguided goal. One can reject color blindness, though, without accepting racial realism... (shrink)

(1) Suppose that you care only about speaking the truth, and are confident that some particular deterministic theory is true. If someone asks you whether that theory is true, are you rationally required to answer "yes"? -/- (2) Suppose that you face a problem in which (as in Newcomb's problem) one of your options---call it "taking two boxes"---causally dominates your only other option. Are you rationally required to take two boxes? -/- Those of us attracted to causal decision theory are (...) under pressure to answer "yes" to both questions. However, it has been shown that many existing decision theories are inconsistent with doing so (Ahmed 2014). A simple proof shows that the same goes for an even wider class of theories: all "suppositional" decision theories. The moral is that causal decision theorists must either answer "no" to one of the above questions, or else abandon suppositional decision theories. (shrink)

I discuss a large number of emotions that are relevant to performance at epistemic tasks. My central concern is the possibility that it is not the emotions that are most relevant to success of these tasks but associated virtues. I present cases in which it does seem to be the emotions rather than the virtues that are doing the work. I end of the paper by mentioning the connections between desirable and undesirable epistemic emotions.

The Significance Argument (SA) for the irreducibility of consciousness is based on a series of new puzzle-cases that I call multiple candidate cases. In these cases, there is a multiplicity of physical-functional properties or relations that are candidates to be identified with the sensible qualities and our consciousness of them, where those candidates are not significantly different. I will argue that these cases show that reductive materialists cannot accommodate the various ways in which consciousness is significant and must allow massive (...) vagueness in conscious experience. I also will argue that a nonreductive theory of the conscious-of relation can easily provide a very satisfying, unified explanation of the ways in which this relation is significant. (shrink)

Despite the ubiquity of knowledge attribution in human social cognition, its associated neural and cognitive mechanisms are poorly documented. A wealth of converging evidence in cognitive neuroscience has identified independent perspective-taking and inhibitory processes for belief attribution, but the extent to which these processes are shared by knowledge attribution isn't presently understood. Here, we present the findings of an EEG study designed to directly address this shortcoming. These findings suggest that belief attribution is not a component process in knowledge attribution, (...) contra a standard attitude taken by philosophers. Instead, observed differences in P3b amplitude indicate that knowledge attribution doesn't recruit the strong self-perspective inhibition characteristic of belief attribution. However, both belief and knowledge attribution were observed to display a late slow wave widely associated with mental state attribution, indicating that knowledge attribution also shares in more general processing of others' mental states. These results provide a new perspective both on how we think about knowledge attribution, as well as Theory of Mind processes generally. (shrink)

G.E. Moore’s writings on external world skepticism show us, in broad outline, how to dispense with external world skepticism in a way that is satisfying, intellectually responsible, and yet avoids engaging in constructive epistemological theory-building altogether. His work thus reveals something very important about the relation between epistemology and ordinary life, and also about what it would take to reach a satisfying resolution of certain sorts of perennial philosophical problems.
