ABSTRACTEmpathy has been taken to play a crucial role in ethics at least since the Scottish Enlightenment. More recently, a revival of moral sentimentalism and empirical research on moral behavior has prompted a renewed interest in empathy and related concepts and on their contribution to moral reasoning and to moral behavior. Furthermore, empathy has recently entered our public discourse as having the power to ameliorate our social and political interactions with others.The aim of this paper is to investigate the extent (...) to which such a role can be actually granted. Before focusing on a positive assessment, I will delve into a few problems our ordinary concept of empathy and our commonsensical way of conceiving its connection to ethics will need to face. Specifically, I will show how an exaggerated reliance on the ordinary concept of empathy could lead to an underestimation of its biases and potential limitations, how a naïve conception of its connection to morality can overlook relevant counterexam...

After introducing some of the many issues raised by intergenerational justice, the paper will focus in particular on the motivational problem: Why should we be motivated to act in favor of others when sacrifices on our behalf are required? And more specifically, how can such sacrifices be justified when those we act for are neither born nor easily unidentifiable? While many accounts of moral motivation exist, most scholars will grant that emotional engagement is a strong motivational drive. Hence, the paper (...) will focus on such a drive. I will, first, argue that immediate emotions and empathy – understood uniquely as a form of emotional attunement – are insufficient to grant that the acts they motivate are morally acceptable. The case of future generations is a perfect example of such insufficiency. Second, I will discuss the possibility of regulated emotions and sympathy playing such a role. In fact, by regulating and educating emotions, a conscious or “rational” component is added, which could help avoid the biases and limitations immediate affective phenomena show. Such a “rational” component would also enable us to provide a criterion to distinguish cases in which emotions drive us in morally acceptable or unacceptable directions. In the second part of the paper, the sentimentalist tradition will be reconsidered, with particular attention to Adam Smith’s moral proposal – since the sympathetic engagement of an impartial spectator could be an excellent example of a regulated and educated emotional attunement of the kind required to deal with some of the many moral issues future generations raise and, in particular, with the motivational problem itself.

In this paper I will try to provide some arguments against a broad definition of “empathy”. Firstly, I will deal with attempts to define empathy as an umbrella concept. Then, I will try to point out the four main elements which contribute to the confusion that researchers in both the social and political as well as the scientific and philosophical domains face when dealing with empathy. In order to resolve this confusion, I suggest applying David Marr’s distinction to the field (...) of empathy. Instead of providing an umbrella definition for empathy, which tries to account for all the data coming from different disciplines, I believe understanding that there are different levels of explanations and that different disciplines can contribute to each of them will provide a more detailed and less confused definition of empathy.

Riassunto: Nel suo contributo Rosalba Morese si occupa di tre fenomeni di particolare interesse per comprendere il modo in cui gli esseri umani di fatto si comportano nei confronti dei loro simili quando sono coinvolte le loro identità di gruppo, ovvero l’altruismo parrocchiale, la punizione antisociale e la punizione altruistica. Scopo di questo lavoro è indagare se e in quale misura i dati comportamentali e di risonanza magnetica funzionale riportati da Morese possano informare le nostre teorie morali normative. Se, cioè, (...) esse possano non solo informarci circa il modo in cui di fatto gli esseri umani si comportano, ma se possano influire sulla nostra comprensione di come essi dovrebbero comportarsi; se dicano qualcosa del “dover essere” oltre che dell’“essere”. Parole chiave: Altruismo parrocchiale; Punizione antisociale; Punizione altruistica; Etica descrittiva; Etica normativa Parochial Altruism, Antisocial Punishment, and Altruistic Punishment: What Contribution Can Empirical Data Make to the Understanding of Ethics?: In her contribution, Morese takes into account three phenomena that are particularly interesting for understanding how human beings actually behave towards others when their group identities are involved – i.e. parochial altruism, antisocial punishment, and altruistic punishment. The aim of this commentary is to understand if and to what extent the behavioral and fMRI data reported by Morese can also inform our moral normative theories. That is, if they can inform us not only about how human beings actually behave, but also influence our understanding of how they should behave; if they tell us something about the “ought” as well as the “is”.

: Within the otherwise lively debate on neuroethics, little attention has been devoted to the peculiar methodological issues and challenges it faces. My aim is to track down its methodological specificities. Firstly, I will investigate to which traditional debates neuroethics bears similarity and to what extent it actually represents a novelty in ethical thinking. While the ethics of neuroscience is akin to bioethics, the neuroscience of ethics seems akin to moral psychology. And yet they differ as far as the level (...) of explanation of human moral behavior and reasoning is concerned. Thus, while the neuroscience of ethics and moral psychology share a family resemblance, they cannot be reduced to one another. Secondly, I will explore three different philosophical temperaments towards the role empirical findings can and should have in normative ethics and in metaethics. Prudential reasons would recommend openness to new sources of evidence without risking either reductionism nor neglect. Keywords: Neuroethics; Methods; Moral Psychology; Empirical Ethics; Levels of Explanation I metodi della neuroetica: la neuroscienza dell’etica è davvero una nuova sfida per la filosofia morale? Riassunto: Nonostante il dibattito in ambito neuroetico sia molto vivace, poca attenzione è stata dedicata alla questione relativa al suo metodo specifico e ai problemi a cui va incontro. Il mio scopo è quello di identificare le specificità metodologiche di questa disciplina. Anzitutto cercherò di determinare a quali dibattiti tradizionali la neuroetica può essere avvicinata e in che misura invece questa costituisce una novità all’interno del pensiero etico. Mentre l’etica della neuroscienza ha delle affinità con la bioetica, la neuroscienza dell’etica appare maggiormente simile alla psicologia morale, sebbene tali discipline siano diverse fra loro per via del livello a cui spigano il comportamento morale umano e il ragionamento. Pertanto, nonostante la neuroscienza dell’etica e la psicologia morale rivelino una certa somiglianza di famiglia, non è possibile ridurre l’una all’altra. In secondo luogo esplorerò tre diversi atteggiamenti filosofici rispetto al ruolo che i risultati empirici giocano o dovrebbero giocare rispetto all’etica normativa e alla metaetica. Ragioni di prudenza suggeriscono di rimanere aperti verso nuove fonti di evidenza evitando tanto il riduzionismo quanto la trascuratezza.

_Riassunto_: La _Deep Brain Stimulation _(DBS) è un dispositivo annoverato tra le interfacce-cervello computer e che si qualifica come una promettente soluzione medica per far fronte al decorso di alcune malattie neurodegenerative come il Parikinson. Decenni di utilizzo clinico della DBS hanno permesso di comprenderne gli effetti collaterali e il loro impatto sul PIAAAS (_Personality, Identity, Agency, Authenticity, Autonomy and Self_). In tal senso, per sondare cambiamenti psicologici legati all’uso della DBS si è fatto ricorso a metodi quantitativi, come questionari (...) incentrati su valutazioni di ordine numerico, e metodi qualitativi, che si appoggiano alle esperienze riportate dai pazienti tramite interviste. Questo articolo ha l’obiettivo di evidenziare come, a prescindere dai metodi di indagine utilizzati, la ricerca sia stata sempre focalizzata sugli effetti collaterali della DBS e gli eventuali cambiamenti sulle dimensioni comprese nel PIAAAS, lasciandosi sfuggire l’occasione di usare i numerosi dati raccolti per effettuare un’analisi fenomenologica che potesse restituirci una descrizione della sintesi uomo-macchina. Per colmare questo iato, proponiamo l’utilizzo sinergico di due metodi di raccolta e analisi dati di origine fenomenologica. _Parole chiave_: Deep Brain Stimulation; Effetti collaterali; Sintesi uomo-macchina; Fenomenologia _Deep Brain Stimulation and the human-machine synthesis: A possible phenomenological perspective_ _Abstract_: Deep Brain Stimulation (DBS) is a device included among the brain-computer interfaces and that qualifies as a promising medical solution to cope with the course of some neurodegenerative diseases such as Parikinson’s. Decades of clinical use of DBS have allowed us to understand its side effects and their impact on PIAAAS (_Personality, Identity, Agency, Authenticity, Autonomy and Self_). In this sense, to investigate psychological changes related to the use of DBS, quantitative methods, such as questionnaires focused on numerical assessments, and qualitative techniques, which are based on experiences by patients through interviews, have been used. This article aims to highlight how, regardless of the survey methods used, research has always been focused on the side effects of DBS and possible changes in the concepts included in the PIAAAS, missing the opportunity to use the numerous data collected to carry out a phenomenological analysis that could give us a description of the human-machine synthesis. To bridge this hiatus, we propose the synergistic use of two phenomenological methods of data collection and analysis. _Keywords_: Deep Brain Stimulation; Side Effects; Human-machine synthesis; Phenomenology.

Background. Since the nineties, policymakers and theorists working across several disciplines started to entertain the notion of directly engaging the public in matters of public concern. Accompanying this was the attempt to resort to deliberative democracy in order to make such an involvement effective. Seizing on its intrinsic dialogic nature, some scholars proposed the application of public deliberation to the realm of public bioethics. Drawing upon the theory and practice of deliberative public bioethics, the purpose of this paper is to (...) shed light onto the figure of the bioethical expert and its role in public bioethics, and relatedly, to investigate how deliberation may be implemented in a public bioethics context. Methods. We set up a large-scale experiment to investigate whether, and to what extent, different moderation styles impact on participants’ moral preferences. The study combines a survey of a representative sample of the general population with a laboratory experiment based on a random sample of students that ex-ante has identical attitudes to the general population.Results. Findings show that: i) different moderation styles can significantly influence deliberative outcomes; iii) the effects of deliberation are not necessarily immediate, but may be revealed after the end of deliberative session; iii) participants tend to better appreciate a bioethical expert acting as “passive moderator”, namely as someone who acts in order to ensure non-domination and non-interference, thus allowing the creation of basic conditions for equality within the deliberative setting.Conclusions. Our experiment represents an example of how deliberation can be employed in public bioethics. (shrink)

This article examines whether people share the Gettier intuition (viz. that someone who has a true justified belief that p may nonetheless fail to know that p) in 24 sites, located in 23 countries (counting Hong Kong as a distinct country) and across 17 languages. We also consider the possible influence of gender and personality on this intuition with a very large sample size. Finally, we examine whether the Gettier intuition varies across people as a function of their disposition to (...) engage in “reflective” thinking. (shrink)

In the remainder of this article, we will disarm an important motivation for epistemic contextualism and interest-relative invariantism. We will accomplish this by presenting a stringent test of whether there is a stakes effect on ordinary knowledge ascription. Having shown that, even on a stringent way of testing, stakes fail to impact ordinary knowledge ascription, we will conclude that we should take another look at classical invariantism. Here is how we will proceed. Section 1 lays out some limitations of previous (...) research on stakes. Section 2 presents our study and concludes that there is little evidence for a substantial stakes effect. Section 3 responds to objections. The conclusion clears the way for classical invariantism.

Since at least Hume and Kant, philosophers working on the nature of aesthetic judgment have generally agreed that common sense does not treat aesthetic judgments in the same way as typical expressions of subjective preferences—rather, it endows them with intersubjective validity, the property of being right or wrong regardless of disagreement. Moreover, this apparent intersubjective validity has been taken to constitute one of the main explananda for philosophical accounts of aesthetic judgment. But is it really the case that most people (...) spontaneously treat aesthetic judgments as having intersubjective validity? In this paper, we report the results of a cross‐cultural study with over 2,000 respondents spanning 19 countries. Despite significant geographical variations, these results suggest that most people do not treat their own aesthetic judgments as having intersubjective validity. We conclude by discussing the implications of our findings for theories of aesthetic judgment and the purpose of aesthetics in general. (shrink)

Philosophers have long debated whether, if determinism is true, we should hold people morally responsible for their actions since in a deterministic universe, people are arguably not the ultimate source of their actions nor could they have done otherwise if initial conditions and the laws of nature are held fixed. To reveal how non-philosophers ordinarily reason about the conditions for free will, we conducted a cross-cultural and cross-linguistic survey (N = 5,268) spanning twenty countries and sixteen languages. Overall, participants tended (...) to ascribe moral responsibility whether the perpetrator lacked sourcehood or alternate possibilities. However, for American, European, and Middle Eastern participants, being the ultimate source of one’s actions promoted perceptions of free will and control as well as ascriptions of blame and punishment. By contrast, being the source of one’s actions was not particularly salient to Asian participants. Finally, across cultures, participants exhibiting greater cognitive reflection were more likely to view free will as incompatible with causal determinism. We discuss these findings in light of documented cultural differences in the tendency toward dispositional versus situational attributions. (shrink)

Does the Ship of Theseus present a genuine puzzle about persistence due to conflicting intuitions based on “continuity of form” and “continuity of matter” pulling in opposite directions? Philosophers are divided. Some claim that it presents a genuine puzzle but disagree over whether there is a solution. Others claim that there is no puzzle at all since the case has an obvious solution. To assess these proposals, we conducted a cross-cultural study involving nearly 3,000 people across twenty-two countries, speaking eighteen (...) different languages. Our results speak against the proposal that there is no puzzle at all and against the proposal that there is a puzzle but one that has no solution. Our results suggest that there are two criteria—“continuity of form” and “continuity of matter”— that constitute our concept of persistence and these two criteria receive different weightings in settling matters concerning persistence.

Is behavioral integration a necessary feature of belief in folk psychology? Our data from over 5,000 people across 26 samples, spanning 22 countries suggests that it is not. Given the surprising cross-cultural robustness of our findings, we argue that the types of evidence for the ascription of a belief are, at least in some circumstances, lexicographically ordered: assertions are first taken into account, and when an agent sincerely asserts that p, nonlinguistic behavioral evidence is disregarded. In light of this, we (...) take ourselves to have discovered a universal principle governing the ascription of beliefs in folk psychology. (shrink)

In this analysis I apply a Foucauldian approach to ethics to examine the politically prescribed moral and ethical character required of carers of aged persons at home in Australia and the role of nurses in shaping these behaviours. The work that spousal carers provide, although often founded on love and/or obligation, has been formalized through a variety of policy initiatives and technologies that serve to construct the moral approach they must adopt. This shaping of conduct at the most personal level (...) takes place through the application of codes of behaviour policed largely by nurses. These codes redefine the mode of coexistence between an aged husband and wife and propose a new form of relationship that is derived from and supports policies of the deinstitutionalization of care services for elderly persons. In this way modern carer policy has drawn on knowledge and governance of the self to produce a morality of caring that is both authoritative and scientific. (shrink)

This paper considers the justifications for adhering to a principle of confidentiality within medical practice. These are found to derive chiefly from respect for individual autonomy, the doctor/patient contract, and social utility. It is suggested that these will benefit more certainly if secrecy is rejected and the principle of confidentiality is removed from the area of health care.

In this chapter, we critique a concept of resilience that has emerged from contemporary positive psychology and its application to health education. We argue that the present popularity of “resilience” as a strategy for managing mental health discourages educational institutions from providing students with the mental health services they need. Using the tools of American pragmatism, especially the work of John Dewey, we criticize the paradigm of resilience and identify several concrete reformulations of disability studies which would make concrete differences (...) in the lives of those with mental disability.

Traditional philosophical discussions of knowledge have focused on the epistemic status of full beliefs. In this book, Moss argues that in addition to full beliefs, credences can constitute knowledge. For instance, your .4 credence that it is raining outside can constitute knowledge, in just the same way that your full beliefs can. In addition, you can know that it might be raining, and that if it is raining then it is probably cloudy, where this knowledge is not knowledge of propositions, (...) but of probabilistic contents. -/- The notion of probabilistic content introduced in this book plays a central role not only in epistemology, but in the philosophy of mind and language as well. Just as tradition holds that you believe and assert propositions, you can believe and assert probabilistic contents. Accepting that we can believe, assert, and know probabilistic contents has significant consequences for many philosophical debates, including debates about the relationship between full belief and credence, the semantics of epistemic modals and conditionals, the contents of perceptual experience, peer disagreement, pragmatic encroachment, perceptual dogmatism, and transformative experience. In addition, accepting probabilistic knowledge can help us discredit negative evaluations of female speech, explain why merely statistical evidence is insufficient for legal proof, and identify epistemic norms violated by acts of racial profiling. Hence the central theses of this book not only help us better understand the nature of our own mental states, but also help us better understand the nature of our responsibilities to each other.

This paper develops a precise understanding of the thesis of moral encroachment, which states that the epistemic status of an opinion can depend on its moral features. In addition, I raise objections to existing accounts of moral encroachment. For instance, many accounts fail to give sufficient attention to moral encroachment on credences. Also, many accounts focus on moral features that fail to support standard analogies between pragmatic and moral encroachment. Throughout the paper, I discuss racial profiling as a case study, (...) arguing that moral encroachment can help us identify one respect in which racial profiling is epistemically problematic.

Generic generalizations such as ‘mosquitoes carry the West Nile virus’ or ‘sharks attack bathers’ are often accepted by speakers despite the fact that very few members of the kinds in question have the predicated property. Previous work suggests that such low-prevalence generalizations may be accepted when the properties in question are dangerous, harmful, or appalling. This paper argues that the study of such generic generalizations sheds light on a particular class of prejudiced social beliefs, and points to new ways in (...) which those beliefs might be undermined and combatted.

Existing discussions of legal proof address a host of apparently disparate questions: What does it take to prove a fact beyond a reasonable doubt? Why is the reasonable doubt standard notoriously elusive, sometimes considered by courts to be impossible to define? Can the standard of proof by a preponderance of the evidence be defined in terms of probability thresholds? Why is statistical evidence often insufficient to meet the burden of proof? -/- This paper defends an account of proof that addresses (...) each of these questions. Where existing theories take a piecemeal approach to these puzzles, my theory develops an insight that unifies them—namely, the thesis that legal proof requires knowledge. Although this thesis may seem radical at first, I answer several common objections to it, and I argue that it does better than several competing accounts when it comes to making sense of our intuitions about what legal proof requires.

This paper motivates and develops a novel semantics for several epistemic expressions, including possibility modals and indicative conditionals. The semantics I defend constitutes an alternative to standard truth conditional theories, as it assigns sets of probability spaces as sentential semantic values. I argue that what my theory lacks in conservatism is made up for by its strength. In particular, my semantics accounts for the distinctive behavior of nested epistemic modals, indicative conditionals embedded under probability operators, and instances of constructive dilemma (...) containing epistemic vocabulary.

This chapter defines and defends time-slice epistemology, according to which there are no essentially diachronic norms of rationality. The chapter begins by distinguishing two notions of time-slice epistemology, and ends by defending time-slice theories of action under indeterminacy, i.e. theories about how you should act when the outcome of your decision depends on some indeterminate claim. In a recent chapter, J. Robert G. Williams defends a theory of action under indeterminacy which is subject to several objections. An alternative theory is (...) proposed in its place. The resulting discussion highlights a more general moral about action under indeterminacy, namely that time-slice theories are supported by strong analogies with ethical theories. In particular, our understanding of agents torn between interpretations of a decision situation should be guided by our theories of agents torn between incommensurable values. (shrink)

This paper argues that just as full beliefs can constitute knowledge, so can properties of your credence distribution. The resulting notion of probabilistic knowledge helps us give a natural account of knowledge ascriptions embedding language of subjective uncertainty, and a simple diagnosis of probabilistic analogs of Gettier cases. Just like propositional knowledge, probabilistic knowledge is factive, safe, and sensitive. And it helps us build knowledge-based norms of action without accepting implausible semantic assumptions or endorsing the claim that knowledge is interest-relative.

Aristotle connects modality and time in ways strange and perplexing to modern readers. In this book the author proposes a new solution to this exegetical problem.

This paper defends an account of full belief, including an account of its relationship to credence. Along the way, I address several familiar and difficult questions about belief. Does fully believing a proposition require having maximal confidence in it? Are rational beliefs closed under entailment, or does the preface paradox show that rational agents can believe inconsistent propositions? Does whether you believe a proposition depend partly on your practical interests? My account of belief resolves the tension between conflicting answers to (...) these questions that have been defended in the literature. In addition, my account complements fruitful probabilistic theories of assertion and knowledge. (shrink)

Ducks lay eggs' is a true sentence, and `ducks are female' is a false one. Similarly, `mosquitoes carry the West Nile virus' is obviously true, whereas `mosquitoes don't carry the West Nile virus' is patently false. This is so despite the egg-laying ducks' being a subset of the female ones and despite the number of mosquitoes that don't carry the virus being ninety-nine times the number that do. Puzzling facts such as these have made generic sentences defy adequate semantic treatment. (...) However complex the truth conditions of generics appear to be, though, young children grasp generics more quickly and readily than seemingly simpler quantifiers such as `all' and `some'. I present an account of generics that not only illuminates the strange truth conditions of generics, but also explains how young children find them so comparatively easy to acquire. I then argue that generics give voice to our most cognitively primitive generalizations and that this hypothesis accounts for a variety of facts ranging from acquisition patterns to cross-linguistic data concerning the phonological articulation of operators. I go on to develop an account of the nature of these cognitively fundamental generalizations and argue that this account explains the strange truth-conditional behavior of generics. (shrink)

One of the main themes that has emerged from behavioral decision research during the past three decades is the view that people's preferences are often constructed in the process of elicitation. This idea is derived from studies demonstrating that normatively equivalent methods of elicitation (e.g., choice and pricing) give rise to systematically different responses. These preference reversals violate the principle of procedure invariance that is fundamental to all theories of rational choice. If different elicitation procedures produce different orderings of options, (...) how can preferences be defined and in what sense do they exist? This book shows not only the historical roots of preference construction but also the blossoming of the concept within psychology, law, marketing, philosophy, environmental policy, and economics. Decision making is now understood to be a highly contingent form of information processing, sensitive to task complexity, time pressure, response mode, framing, reference points, and other contextual factors.

Recently, von Fintel (2001) and Gillies (2007) have argued that certain sequences of counterfactuals, namely reverse Sobel sequences, should motivate us to abandon standard truth conditional theories of counterfactuals for dynamic semantic theories. I argue that we can give a pragmatic account of our judgments about counterfactuals without giving up the standard semantics. In particular, I introduce a pragmatic principle governing assertability, and I use this principle to explain a variety of subtle data concerning reverse Sobel sequences.

Recently many have argued that agents must sometimes have credences that are imprecise, represented by a set of probability measures. But opponents claim that fans of imprecise credences cannot provide a decision theory that protects agents who follow it from foregoing sure money. In particular, agents with imprecise credences appear doomed to act irrationally in diachronic cases, where they are called to make decisions at earlier and later times. I respond to this claim on behalf of imprecise credence fans. Once (...) we appreciate the complexity of our intuitions about rational decision making, we can see that diachronic cases are in fact evidence for the essential claims motivating imprecise credence models. I argue that our decision theory for imprecise agents should mirror our decision theory for agents in moral dilemmas, and I develop permissive norms that explain our intuitions about both sorts of agents.

This paper discusses three potential varieties of update: updates to the common ground, structuring updates, and updates that introduce discourse referents. These different types of update are used to model different aspects of natural language phenomena. Not-at-issue information directly updates the common ground. The illocutionary mood of a sentence structures the context. Other updates introduce discourse referents of various types, including propositional discourse referents for at-issue information. Distinguishing these types of update allows a unified treatment of a broad range of (...) phenomena, including the grammatical evidentials found in Cheyenne (Algonquian) as well as English evidential parentheticals, appositives, and mood marking. An update semantics that can formalize all of these varieties of update is given, integrating the different kinds of semantic contributions into a single representation of meaning. (shrink)

Many languages grammatically mark evidentiality, i.e., the source of information. In assertions, evidentials indicate the source of information of the speaker while in questions they indicate the expected source of information of the addressee. This dissertation examines the semantics and pragmatics of evidentiality and illocutionary mood, set within formal theories of meaning and discourse. The empirical focus is the evidential system of Cheyenne (Algonquian: Montana), which is analyzed based on several years of fieldwork by the author.

Traditionally, discussions of moral participation – and in particular moral agency – have focused on fully formed human actors. There has been some interest in the development of morality in humans, as well as interest in cultural differences when it comes to moral practices, commitments, and actions. However, until relatively recently, there has been little focus on the possibility that nonhuman animals have any role to play in morality, save being the objects of moral concern. Moreover, when nonhuman cases are (...) considered as evidence of moral agency or subjecthood, there has been an anthropocentric tendency to focus on those behaviors that inform our attributions of moral agency to humans. For example, some argue that the ability to evaluate the principles upon which a moral norm is grounded is required for full moral agency. Certainly, if a moral agent must understand what makes an action right or wrong, then most nonhuman animals would not qualify (and perhaps some humans too). However, if we are to understand the evolution of moral psychology and moral practice, we need to turn our attention to the foundations of full moral agency. We must first pay attention to the more broadly normative practices of other animals. Here, we begin that project by considering evidence that great apes and cetaceans participate in normative practices. (shrink)

It is commonly assumed that when we assign different credences to a proposition, a perfect compromise between our opinions simply ‘splits the difference’ between our credences. I introduce and defend an alternative account, namely that a perfect compromise maximizes the average of the expected epistemic values that we each assign to alternative credences in the disputed proposition. I compare the compromise strategy I introduce with the traditional strategy of compromising by splitting the difference, and I argue that my strategy is (...) a reasonable characterization of epistemic compromise.

Collaboration requires agents to coordinate their behavior on the fly, sometimes cooperating to solve a single task together and other times dividing it up into sub‐tasks to work on in parallel. Underlying the human ability to collaborate is theory‐of‐mind (ToM), the ability to infer the hidden mental states that drive others to act. Here, we develop Bayesian Delegation, a decentralized multi‐agent learning mechanism with these abilities. Bayesian Delegation enables agents to rapidly infer the hidden intentions of others by inverse planning. (...) We test Bayesian Delegation in a suite of multi‐agent Markov decision processes inspired by cooking problems. On these tasks, agents with Bayesian Delegation coordinate both their high‐level plans (e.g., what sub‐task they should work on) and their low‐level actions (e.g., avoiding getting in each other's way). When matched with partners that act using the same algorithm, Bayesian Delegation outperforms alternatives. Bayesian Delegation is also a capable ad hoc collaborator and successfully coordinates with other agent types even in the absence of prior experience. Finally, in a behavioral experiment, we show that Bayesian Delegation makes inferences similar to human observers about the intent of others. Together, these results argue for the centrality of ToM for successful decentralized multi‐agent collaboration. (shrink)

The concept of "nature as inner principle of change" is fundamental to Aristotle's theory of the physical world; it is the object of the present thesis to substantiate this claim by tracing the effects of this idea in Aristotle's rejection of materialism, in his doctrine of "natural places", in his definition of change and process in general, and in his notion of agency in general and the supreme Unmoved Mover in particular ). Aristotle elucidates "natural" by. contrast with "artificial" - (...) ), holding that natural substances not merely collectively - ) but as individuals each possess an 'innate impulse of change'. But this must be explained so as to allow for the fact that no change is entirely independent of external conditions - ). If, however, change were totally dependent on external conditions, its occurrence would be inexplicable - ), and the very concept of "change" would be incoherent. This latter conclusion emerges from an examination of the ancient paradox of becoming and Aristotle's treatment of it - ). The paradox is expounded -). Aristotle answers it by showing that language assumes a continuing subject of change - ). But this assumption meets the problem only if the metaphysical category of substance is also assumed, and along with it some distinction between substance-constitutive and non-substance-constitutive characteristics - ). The former mark off their subject as a thing of a certain causal type; thus change, in presupposing a substantial subject, presupposes one that makes some causal contribution to its own changes - ). But Aristotle means more than this by 'nature as inner principle'. He holds a natural substance to be the autonomous determinant of certain changes; these therefore are "natural", as manifesting the substantial nature - ). This problematic notion is taken for granted by Aristotle in the Vhys-ics - ), but can be seen to rest on his metaphysic of substance. It is a consequence of this that the natural change of a given substance be of one kind and display a unitary pattern reflecting the unity of the substance ). This view cripples scientific method as we understand it ), but Aristotle's idea of substance anyway cuts him off from the approaches successfully operated in later mechanics and chemistry - ). A summary of the ground so far covered ) introduces a further sense in which Aristotle's natures are "inner" principles of change: the subject of change is not external to the being which is the source of change - ).

The present paper focuses on essentialism about natural kinds as a case study in order to illustrate this more general point. Saul Kripke and Hilary Putnam famously argued that natural kinds have essences, which are discovered by science, and which determine the extensions of our natural kind terms and concepts. This line of thought has been enormously influential in philosophy, and is often taken to have been established beyond doubt. The argument for the conclusion, however, makes critical use of intuitions, (...) and I note that the intuitions are of the sort had by preschool children, and that they are traceable to a deep-seated cognitive outlook, which is often called “psychological essentialism.” Further, if we did not have such a cognitive outlook or implicit belief set—a belief set which is in fact in place by at least age 4—then we would not have the relevant philosophical intuitions. In light of this, I consider the question of whether natural kinds actually have scientifically discovered or discoverable essences, and whether these putative essences could determine the extensions of our terms and concepts as Kripke, Putnam, and many others have supposed. In fact, a number of philosophers of biology and chemistry have argued that biological and chemical kinds do not have such essences, yet these arguments—particularly in the case of chemistry—have not been assimilated by philosophers more generally. The reason for this poor assimilation is, I suggest, that the Kripke/Putnam view is just so intuitive. But this fact, I argue, is due to a deep-seated cognitive bias, rather than to any special insight into the nature of reality. (shrink)
