In reinforcement learning, a decision maker searching for the most rewarding option is often faced with the question: What is the value of an option that has never been tried before? One way to frame this question is as an inductive problem: How can I generalize my previous experience with one set of options to a novel option? We show how hierarchical Bayesian inference can be used to solve this problem, and we describe an equivalence between the Bayesian model and (...) temporal difference learning algorithms that have been proposed as models of RL in humans and animals. According to our view, the search for the best option is guided by abstract knowledge about the relationships between different options in an environment, resulting in greater search efficiency compared to traditional RL algorithms previously applied to human cognition. In two behavioral experiments, we test several predictions of our model, providing evidence that humans learn and exploit structured inductive knowledge to make predictions about novel options. In light of this model, we suggest a new interpretation of dopaminergic responses to novelty. (shrink)

Across species, animals have an intrinsic drive to approach appetitive stimuli and to withdraw from aversive stimuli. In affective science, influential theories of emotion link positive affect with strengthened behavioural approach and negative affect with avoidance. Based on these theories, we predicted that individuals’ positive and negative affect levels should particularly influence their behaviour when innate Pavlovian approach/avoidance tendencies conflict with learned instrumental behaviours. Here, across two experiments – exploratory Experiment 1 (N = 91) and a preregistered confirmatory Experiment 2 (...) (N = 335) – we assessed how induced positive and negative affect influenced Pavlovian-instrumental interactions in a reward/punishment Go/No-Go task. Contrary to our hypotheses, we found no evidence for a main effect of positive/negative affect on either approach/avoidance behaviour or Pavlovian-instrumental interactions. However, we did find evidence that the effects of induced affect on behaviour were moderated by individual differences in self-reported behavioural inhibition and gender. Exploratory computational modelling analyses explained these demographic moderating effects as arising from positive correlations between demographic factors and individual differences in the strength of Pavlovian-instrumental interactions. These findings serve to sharpen our understanding of the effects of positive and negative affect on instrumental behaviour. (shrink)

Considerable attention in bioethics has been devoted to moral expertise and its implications for handling applied moral problems. The existence and nature of moral expertise has been a contested topic, and particularly, whether philosophers are moral experts. In this study, we put the question of philosophers’ moral expertise in a wider context, utilizing a novel and global study among 4,087 philosophers from 96 countries. We find that despite the skepticism in recent literature, the vast majority of philosophers do believe in (...) moral expertise and in the contribution of philosophical training and experience to its acquisition. Yet, they still differ on what philosophers’ moral expertise consists of. While they widely accept that philosophers possess superior analytic abilities regarding moral matters, they diverge on whether they also possess improved ability to judge moral problems. Nonetheless, most philosophers in our sample believe that philosophers possess an improved ability to both analyze and judge moral problems and that they commonly see these two capacities as going hand in hand. We also point at significant associations between personal and professional attributes and philosophers’ beliefs, such as age, working in the field of moral philosophy, public involvement, and association with the analytic tradition. We discuss the implications of these findings for the debate about moral expertise. -/- . (shrink)

"Semantic Truth Theories" uses the techniques of mathematical logic to develop a new semantic treatment of the concept of truth based on ideas of Saul Kripke. Yael Cohen goes on to solve the Liar paradox, Hempel's raven paradox in the philosophy of science, and other classical problems of philosophy. She does this by enlarging the scope of formal logic to include concepts of presupposition besides the usual implication. The book thus provides a unified treatment of many topics having to (...) do with truth, topics whose deep and unsuspected interconnections are not visible without the insights of mathematical knowledge which the author elaborates. The early chapters of the book contain an accessible introduction to semantic paradoxes which should be useful to students. (shrink)

Contemporary realities of global population movement increasingly bring to the fore the challenge of quality and equitable health provision across language barriers. While this linguistic challenge is not unique to immigration contexts and is likewise shared by health systems responding to the needs of aboriginal peoples and other historical linguistic minorities, the expanding multilingual landscape of receiving societies renders this challenge even more critical, owing to limited or even non‐existing familiarity of modern and often monolingual health systems with the particular (...) needs of new linguistic minorities. The centrality of language to health beliefs, attitudes, practices, cultural scripts, and conceptual frameworks emphasizes its pivotal role in the healthcare process, and consequently in the adverse effects of treatment that is language‐insensitive and unaware. Such an attitude on the part of medical authorities risks considerable epistemic injustice in the form of a (mis)judgement of patients’ intelligence, credibility, and rationality based on the language that they speak and the manner in which they speak it, consequently impacting the quality and equity of care provided. This danger, I argue, may be effectively countered by fostering among the participants in the healthcare process a sense of epistemic humility through greater metalinguistic awareness. Outlining a range of operative steps that can be used to facilitate this. I argue that the reality of language barriers in the healthcare process, while not entirely eliminable, may nevertheless be successfully addressed, in order to mitigate the challenge of quality and equitable healthcare provision in multilingual societies.

In this erudite study, Anna Becker employs the lens of gender to explore the political thought of nine Renaissance writers. She argues that political thinkers in the Italian and French Renaissance perceived the domestic realm to be essentially political, particularly within relationships of marriage and parenting. She demonstrates that "The Great Dichotomy"—the assumed binary opposition between a public-civic realm that is political and male, and a private-domestic realm that is apolitical and female—did not exist in canonical Renaissance political thought.The first (...) chapter closely examines how three Italian commentators, Leonardo Bruni, Donato Acciaioli, and Bernardo Segni...

Language is central to political philosophy, yet until now there has been little in the way of a common framework capable of bridging disciplines that share an interest in language, power, and ethics. Studies are predominantly carried out in isolated disciplinary silos - notably linguistics, philosophy, political science, public administration, and education. This volume proposes a new vision for understanding the political ethics of language, particularly in linguistically diverse societies, and it establishes the necessary common framework for this field of (...) inquiry: language ethics. Through creative and constructive thinking, Language Ethics considers how to advance our understanding of the human commonalities of moral and linguistic capacities and the challenge of linguistic difference and societal interdependence. The book embraces the longstanding centrality of language to moral reasoning and reinterprets it in a manner that draws on the social and political life of real-world inter- and intralinguistic issues. Contributors to this collection are leading international experts from different disciplines and approaches whose voices add diverse insight to the discourse on ethics and language justice. Exploring social, political, and economic realities, Language Ethics illuminates the complex nexus between ethics and language and highlights the contemporary challenges facing multilingual societies, including the uncertainties, ambiguities, anxieties, and hopes that accompany them.

"This is a most timely, intelligent, well-written, and absorbing essay on a central and painful social and political problem of out time."--Sir Isaiah Berlin"The major achievement of this remarkable book is a critical theory of nationalism, worked through historical and contemporary examples, explaining the value of national commitments and defining their moral limits. Tamir explores a set of problems that philosophers have been notably reluctant to take on, and leaves us all in her debt."--Michael WalzerIn this provocative work, Yael (...) Tamir urges liberals not to surrender the concept of nationalism to conservative, chauvinist, or racist ideologies. In her view, liberalism, with its respect for personal autonomy, reflection, and choice, and nationalism, with its emphasis on belonging, loyalty, and solidarity are not irreconcilable. Here she offers a new theory, "liberal nationalism," which allows each set of values to accommodate the other. Tamir sees nationalism as an affirmation of communal and cultural memberships and as a quest for recognition and self-respect. Persuasively she argues that national groups can enjoy these benefits through political arrangements other than the nation-state. While acknowledging that nationalism places members of national minorities at a disadvantage, the author offers guidelines for alleviating the problems involved using examples from currents conflicts in the Middle East and in Eastern Europe.Liberal Nationalismis an impressive attempt to tie together a wide range of issues often kept apart: personal autonomy, cultural membership, political obligations, particularity versus impartiality in moral duties, and global justice. Drawing on material from disparate fields--including political philosophy, ethics, law, and sociology--Tamir brings out important and previously unnoticed interconnections between them, offering a new perspective on the influence of nationalism on modern political philosophy.

1000 time-travelers travel back in time, each with the intention of killing their own infant-self. If there is no branching time, then on pain of bringing about a logical contradiction, all must fail. But this seems inexplicable: what is to ensure that the time-travelers are stopped? For a time, this inexplicability objection was thought to provide evidence that there is something incoherent about the possibility of backwards time travel in a universe without branching time. There is now near-consensus, however, that (...) the objection has no bite: there is nothing inexplicable about the mass failure. Lewis, Sider and Ismael independently argue that since it is built into the description of the class of cases considered that the time-travelers must fail – and so we consider only unsuccessful attempts – there is no mystery. Smith argues that the absence of possible worlds at which auto-infanticide is committed suffices as a complete explanation for the failures. And Baron and Colyvan maintain that available causal and logical explanations jointly account for everything that needs accounting for. I argue that these are wrong. There is remaining, problematic inexplicability. For backwards time travel not to lead to logical contradiction, something would need to do logic’s bidding, after all. (shrink)

Are philosophers moral experts, and if so, what does this imply for their proper role in moral decision-making? The dominant view on this subject argues that philosophers have superior moral understanding, but they are not better judges of what is morally right. Consequently, philosophers cannot and should not have an authoritative role in moral decision-making. In this article, I challenge this view and argue that an examination of the intimate connection between two capacities – to understand and to judge – (...) reveals that it is both inconsistent and simplistic. It is inconsistent because, all things being equal, if philosophers better understand moral problems, they are also better judges of them. It is simplistic because it adopts an all-or-nothing approach to moral expertise, while expertise is in fact conditional. Inspired by the psychological literature on expertise, I claim that we should not ask whether philosophers are moral experts but rather under which conditions they successfully execute their expertise. The conclusion of the dominant view needs to be reconsidered to reflect the conditional nature of philosophers' expertise. Although more empirical research is required, I offer several hypotheses for future endeavours that demonstrate what a conditional view of philosophers' moral expertise could look like. -/- .

Polysemy is a term used in semantic and lexical analysis to describe a word with multiple meanings. Although such words present few difficulties in everyday communication, they do pose near-intractable problems for linguists and lexicographers. The contributors in this volume consider the implications of these problems for linguistic theory and how they may be addressed in computational linguistics.

Novelty is a pivotal player in cognition, and its contribution to superior memory performance is a widely accepted convention. On the other hand, mnemonic advantages for familiar information are also well documented. Here, we examine the role of experimental distinctiveness as a potential explanation for these apparently conflicting findings. Across two experiments, we demonstrate that conceptual novelty, an unfamiliar combination of familiar constituents, is sensitive to its experimental proportions: Improved memory for novelty was observed when novel stimuli were relatively rare. (...) Memory levels for familiar items, in contrast, were completely unaffected by experimental proportions, highlighting their insensitivity to list-based distinctiveness. Finally, no mnemonic advantage for conceptual novelty over familiarity was observed even when novel stimuli were extremely rare at study. Together, these results imply that novel and familiar items are processed via partially distinct mechanisms, with novelty not providing a mnemonic advantage over familiarity. (shrink)

ABSTRACT The apparent consistency of Sobel sequences famously motivated David Lewis to defend a variably strict conditional semantics for counterfactuals. If Sophie had gone to the parade, she would have seen Pedro. If Sophie had gone to the parade and had been stuck behind someone tall, she would not have seen Pedro. But if the order of the counterfactuals in a Sobel sequence is reversed—in the example, if is asserted prior to —the second counterfactual asserted no longer rings true. This (...) is the Heim sequence problem. That the order of assertion makes this difference is surprising on the variably strict account. Some argue that this is reason to reject the Lewis-Stalnaker semantics outright. Others argue that the problem motivates a contextualist rendering of counterfactuals. Still others maintain that the explanation for the phenomenon is merely pragmatic. I argue that none of these is right, and I defend a novel way to understand the phenomenon. My proposal avoids the problems faced by the alternative analyses and enjoys independent support. There is, however, a difficulty for my view: it entails that many ordinarily accepted counterfactuals are not true. I argue that this cost is acceptable. (shrink)

Is our moral cognition “colored” by the language(s) that we speak? Despite the centrality of language to political life and agency, limited attempts have been made thus far in contemporary political philosophy to consider this possibility. We therefore set out to explore the possible influence of linguistic relativity effects on political thinking in linguistically diverse societies. We begin by introducing the facts and fallacies of the “linguistic relativity” principle, and explore the various ways in which they “color,” often covertly, current (...) normative debates. To illustrate this, we focus on two key Rawlsian concepts: the original position and public reason. We then move to consider the resulting epistemic challenges and opportunities facing contemporary multilingual democratic societies in an age of increased mobility, arguing for the consequent imperative of developing political metalinguistic awareness and political extelligence among political scientists, political philosophers, and political actors alike in an irreducibly complex linguistic world.

This article explores the properties of formulations in a corpus of Hebrew radio phone-ins by juxtaposing two theoretical frameworks: conversation analysis and dialogic syntax. This combination of frameworks is applied towards explaining an anomalous interaction in the collection – a caller’s marked, unexpected rejection of a formulation of gist produced by the radio phone-in’s host. Our analysis shows that whereas previous CA studies of formulations account for many instances throughout the corpus, understanding this particular formulation in CA terms does not (...) explain its drastic rejection by the caller. We therefore turn to an in-depth examination of strategies for lexical and syntactic resonance as a stance-taking device throughout the interaction. In so doing, we not only shed light on the anomalous interaction, but also offer an answer to a provocative question previously put forward by Haddington concerning which of the two – stances or actions – have more meaningful consequences for the description of the organization of interaction. In the particular interaction analyzed here, stances play the more significant role. We propose that the intersubjective stance-taking of participants may be viewed as a meta-action employed among participants as they move across actions, sequences, and activities in talk. (shrink)

The topic of time is central to Levinas's philosophy. By examining aspects of the Biblical stories of Abraham and Moses compared with Greek myths, mainly that of Cronos devouring his children, this paper aims to show that Levinas's view of time, though certainly indebted to the Greek (i.e. philosophical) tradition, contains traces of Biblical experiences. Moreover, Levinas's interpretation of time will serve as a concrete demonstration of the way the Jewish experience enables Levinas to express his criticism of the philosophical‐Greek (...) tradition.

This paper deals with the exceptions-tolerance property of generic sentences with indefinite singular and bare plural subjects (IS and BP generics, respectively) and with the way this property is connected to some well-known observations about felicity differences between the two types of generics (e.g. Lawler's 1973, Madrigals are popular vs. #A madrigal is popular). I show that whereas both IS and BP generics tolerate exceptional and contextually irrelevant individuals and situations in a strikingly similar way, which indicates the existence of (...) a basically equivalent tolerance mechanism, there is also a difference between them, unnoticed so far, which concerns the degree to which the properties of the legitimate exceptions can be characterized in advance. Following claims in Greenberg (2003), I argue that both this newly observed difference as well as the traditional felicity differences result from an underlying contrast in the type of ‘non-accidentalness’ expressed by the two types of generic sentences, and more formally, in the accessibility relations that their generic quantifier (Gen) is compatible with. To capture the new difference in tolerance of exceptions, I develop an improved version of the exceptions-tolerance mechanism for generic sentences suggested in Kadmon & Landman (1993), namely, a restriction on the set of individuals and situations quantified by Gen, which is partially vague to two different degrees using supervaluationist methods. The different degrees of vagueness in this restriction are shown to be systematically dependent on the two types of accessibility relations that IS and BP generics are compatible with, which are redefined as precise and vague restrictions on the generic quantification over worlds.

This study investigates employment of two elements having a lexical source involving comparison -, `like') which have greatly proliferated over the last decade or so in Israel, Hebrew Kaze and ke'ilu. Here I focus particularly on kaze and compare it to ke'ilu, which was investigated at length in Maschler. The data come from audio-recordings of casual conversations of college-educated Israelis with their friends and relatives. A qualitative analysis of talk-in-interaction reveals three functions for kaze: comparative demonstrative, hedge and quotative. A (...) quantitative perspective on the distribution of these functions is presented, and these qualitative and quantitative analyses lead to an examination of the functional itinerary of this word in Hebrew. The recent proliferation of kaze and ke'ilu in Israeli Hebrew discourse is then tied to the change from a culture in which dugri speech is central to one in which this speaking style is in decline.

Just as knowledge contextualism offers a way out of knowledge skepticism in the face of powerful skeptical arguments, counterfactual contextualism purports to answer the many compelling arguments for the skeptical thesis that most ordinary counterfactuals of the form ‘if A had happened, C would have happened’, are false. In this article I review a few of the arguments for counterfactual skepticism, before surveying the various types of contextualist responses. I then discuss some of the recent objections to counterfactual contextualism, with (...) an eye toward weighing contextualism's costs with the costs of accepting skepticism. I conclude by remarking on some of the implications that skepticism and contextualism each has for many disputes in metaphysics. (shrink)

Peter van Inwagen's influential Direct Argument (DA) for the incompatibility of moral responsibility and causal determinism makes use of an inference rule he calls "Rule B." Michael McKenna has argued that van Inwagen's defense of this rule is dialectically inappropriate because it is based entirely on alleged “confirming” cases that are not of the right kind to justify the use of Rule B in DA. Here I argue that McKenna’s objection is on the right track but more must be said (...) if we are to see why. To fill in the gaps I consider a recent attempt by Ira M. Schnall and David Widerker to defend DA against McKenna’s objection. I argue that neither prong of their attack is successful against a variation on McKenna’s basic argument. In the course of responding to Schnall and Widerker’s objections to McKenna, I identify what is, as I argue, the real reason DA fails in its purpose to shift the burden of proof. (shrink)

Boycotts of various types and forms have become in recent years an increasingly common feature of political life. And yet, despite both their ubiquity and clear ethical grounding, they remain to date under-explored in academic philosophy. I examine in this article the question of the ethics of boycotting, using the academic and cultural boycott of Israel as a case study. I propose that the boycott exhibits an intriguing pattern of continuous tension between its own stated principles and its realised practices, (...) and suggest that this tension is not a dysfunction of the boycott but rather a structural feature, which emanates from its primary commitment to the idea of anti-normalisation as an ethical imperative. I explore the complex cross-linguistic political pragmatics of the notion of normalisation, and argue that the commitment to it on the part of the boycott movement, as a group actor, effectively amounts to a capricious form of arbitrary treatment of the boycotted. I then propose that the effective validation of arbitrary treatment constitutes, first, a harm in itself; and, second, that it hinders the capacity of the campaign to draw on and contribute to a general theory of the ethics of boycotting.

The neural basis of progress monitoring has received relatively little attention compared to other sub-processes that are involved in goal directed behavior such as motor control and response inhibition. Studies of error-monitoring have identified the dorsal anterior cingulate cortex (dACC) as a structure that is sensitive to conflict detection, and triggers corrective action. However, monitoring goal progress involves monitoring correct as well as erroneous events over a period of time. In the present research, 20 healthy participants underwent fMRI while playing (...) a game that involved monitoring progress towards either a numerical or a visuo-spatial target. The findings confirmed the role of the dACC in detecting situations in which the current state may conflict with the desired state, but also revealed activations in the frontal and parietal regions, pointing to the involvement of processes such as attention and working memory in monitoring progress over time. In addition, activation of the cuneus was associated with monitoring progress towards a specific target presented in the visual modality. This is the first time that activation in this region has been linked to higher-order processing of goal-relevant information, rather than low-level anticipation of visual stimuli. Taken together, these findings identify the neural substrates involved in monitoring progress over time, and how these extend beyond activations observed in conflict and error monitoring. (shrink)

In 1967 Garfinkel and Bittner were investigating good organizational reasons for bad clinic records, demonstrating how the reading of such records as sociological data should be reported to the understanding of their production’s practical contingencies and to the situated circumstances of their use. This seminal paper opened new avenues of research related to the study of records in various professional contexts and of their transformation, to the development of praxiological approaches to practical and professional texts, or to the study of (...) historical documents and archives. To contribute to this ethnomethodological strand of research, I propose a case-study of artworks’ records management at the museum, investigated as a perspicuous site to reflect upon how artworks are experienced, apprehended and defined in the institutional ordinary business. Drawing on observations and materials collected at the French National Museum of Modern Art, I study records’ careers and describe their material and organizational properties, by giving a close look at some elements. More particularly, I focus on one distinctive property of some records: their thickness, investigated as a scheme of interpretation of the situated features of documentation work. By reading artworks’ records as local collective practices of assemblage, disruption and reconfiguration of pieces of documentation, I demonstrate that what is documented in this process is not only the artwork: it is also the collective work of working with artworks, dealt with as ongoing achievements of institutional practices.

The purpose of this paper is to shed some light on the familiar puzzle of free indirect discourse (FID). FID shares some properties with standard indirect discourse and with direct discourse, but there is currently no known theory that can accommodate such a hybrid. Based on the observation that FID has ‘de se’ pronouns, I argue that it is a kind of an attitude report.

In recent decades, the discipline of bioethics has grown rapidly, as has the practice of ethical consultation. Interestingly, this new recognition of the relevance of moral philosophy to our daily life has been accompanied by skepticism among philosophers regarding the existence of moral expertise or the benefits of philosophical training. In his recent article in Bioethics, William R. Smith suggested that this skepticism is rooted in philosophers' belief that moral expertise is inconsistent with liberal–democratic values, when in fact they are (...) compatible. In this paper, we provide a unique opportunity to empirically examine Smith's observation by utilizing and extending global data on philosophers' beliefs about moral expertise, involving 4087 philosophers from 96 countries. Our findings support Smith's theoretical observation and show that societal levels of support for liberal–democratic values are associated with greater skepticism about moral expertise. We suggest that these findings might be explained by the cognitive process of motivated reasoning and an invalid inference of “is” from “ought.” Consequently, the potential tension between moral expertise and liberal–democratic values is invalidly used for rejecting the existence of moral expertise, while its main and valid implication is for how moral expertise should be applied in liberal–democratic settings.
