Experimental moral philosophy emerged as a methodology in the last decade of the twentieth century, as a branch of the larger experimental philosophy (X-Phi) approach. Experimental moral philosophy is the empirical study of moral intuitions, judgments, and behaviors. Like other forms of experimental philosophy, it involves gathering data using experimental methods and using these data to substantiate, undermine, or revise philosophical theories. In this case, the theories in question concern the nature of moral reasoning and judgment; the extent and sources (...) of moral obligations; the nature of a good person and a good life; even the scope and nature of moral theory itself. This entry begins with a brief look at the historical uses of empirical data in moral theory and goes on to ask what, if anything, is distinctive about experimental moral philosophy—how should we distinguish it from related work in empirical moral psychology? After discussing some strategies for answering this question, the entry examines two of the main projects within experimental moral philosophy, and then discusses some of the most prominent areas of research within the field. As we will see, in some cases experimental moral philosophy has opened up new avenues of investigation, while in other cases it has influenced longstanding debates within moral theory. (shrink)

Response-dependence theories have historically been very popular in aesthetics, and aesthetic response-dependence has motivated response-dependence in ethics. This chapter closely examines the prospects for such theories. It breaks this category down into dispositional and fittingness strands of response-dependence, corresponding to descriptive and normative ideal observer theories. It argues that the latter have advantages over the former but are not themselves without issue. Special attention is paid to the relationship between hedonism and response-dependence. The chapter also introduces two aesthetic properties that (...) lead to wrong kinds of reasons problems for aesthetic response-dependence: insightfulness and the capacity to change one’s perspective. These properties do not have obvious parallels in the ethical domain, and so present an obstacle for response-dependence even in aesthetics. The chapter ends by examining replies on behalf of the response-dependence theorist, ultimately suggesting that a restricted form of response-dependence is the most promising way forward for fans of such theories.

This chapter is centered around an apparent tension that research on implicit bias raises between virtue and social knowledge. Research suggests that simply knowing what the prevalent stereotypes are leads individuals to act in prejudiced ways—biasing decisions about whom to trust and whom to ignore, whom to promote and whom to imprison—even if they reflectively reject those stereotypes. Because efforts to combat discrimination obviously depend on knowledge of stereotypes, a question arises about what to do next. This chapter argues that (...) the obstacle to virtue is not knowledge of stereotypes as such, but the “accessibility” of such knowledge to the agent who has it. “Accessibility” refers to how easily knowledge comes to mind. Social agents can acquire the requisite knowledge of stereotypes while resisting their pernicious influence, so long as that knowledge remains, in relevant contexts, relatively inaccessible.

Can we trust our intuitive judgments of right and wrong? Are moral judgements objective? What reason do we have to do what is right and avoid doing what is wrong? In Conversations on Ethics, Alex Voorhoeve elicits answers to these questions from eleven outstanding philosophers and social scientists: -/- Ken Binmore; Philippa Foot; Harry Frankfurt; Allan Gibbard; Daniel Kahneman; Frances Kamm; Alasdair MacIntyre; T. M. Scanlon; Peter Singer; David Velleman; Bernard Williams. -/- The exchanges are direct, open, and sharp, (...) and give a clear account of these thinkers' core ideas about ethics. They also provide unique insights into their intellectual development - how they became interested in ethics, and how they conceived the ideas for which they became famous. Conversations on Ethics will engage anyone interested in moral philosophy. (shrink)

There are at least two different aspects of our rational evaluation of agents’ doxastic attitudes. First, we evaluate these attitudes according to whether they are supported by one’s evidence (substantive rationality). Second, we evaluate these attitudes according to how well they cohere with one another (structural rationality). In previous work, I’ve argued that substantive and structural rationality really are distinct, sui generis, kinds of rationality – call this view ‘dualism’, as opposed to ‘monism’, about rationality – by arguing that the (...) requirements of substantive and structural rationality can come into conflict. In this paper, I push the dialectic on this issue forward in two main ways. First, I argue that the most promising ways of resisting the diagnosis of my cases as conflicts still end up undermining monism in different ways. Second, supposing for the sake of argument that we should understand the cases as conflicts, I address the question of what we should do when such conflicts arise. I argue that, at least in a prominent kind of conflict case, the coherence requirements take precedence over the evidential requirements. (shrink)

Is there anything wrong with publishing philosophical work which one does not believe (publishing without belief, henceforth referred to as ‘PWB’)? I argue that there is not: the practice isn’t intrinsically wrong, nor is there a compelling consequentialist argument against it. Therefore, the philosophical community should neither proscribe nor sanction it. The paper proceeds as follows. First, I’ll clarify and motivate the problem, using both hypothetical examples and a recent real-world case. Next, I’ll look at arguments that there is something (...) wrong with PWB, and show that none is sound. Then, I’ll give some reasons for thinking a norm against PWB is detrimental to the profession. Do I believe these arguments? If I’m right, it shouldn’t matter. (shrink)

In metaethics, empirical approaches are not just complementary to, but continuous with, traditional approaches to the subject. This chapter addresses traditional and empirical approaches to metaethics. It discusses how empirical approaches have been brought to bear on some central metaethical questions. The chapter illustrates not just the diversity of topics within metaethics itself but also the diversity of empirical methods and approaches that philosophers and psychologists working on these topics are using. The debate between internalists and externalists is a debate (...) concerning the psychology of moral judgment, but also a debate about our concept of moral judgment. As such, it has implications for other metaethical debates. Antirealists such as relativists and noncognitivists often defend internalism, and argue that their views are best equipped to explain the link between moral judgment and motivation. (shrink)

Recent empirical studies have established that disgust plays a role in moral judgment. The normative significance of this discovery remains an object of philosophical contention, however; ‘disgust skeptics’ such as Martha Nussbaum have argued that disgust is a distorting influence on moral judgment and has no legitimate role to play in assessments of moral wrongness. I argue, pace Nussbaum, that disgust’s role in the moral domain parallels its role in the physical domain. Just as physical disgust tracks physical contamination and (...) pollution, so moral disgust tracks social contamination. I begin by examining the arguments for skepticism about disgust and show that these arguments threaten to overgeneralize and lead to a widespread skepticism about the justifiability of our moral judgments. I then look at the positive arguments for according disgust a role in moral judgment, and suggest that disgust tracks invisible social contagions in much the same way as it tracks invisible physical contagions, thereby serving as a defense against the threat of socio-moral contamination.

Context-sensitive expressions appear ill suited to the purpose of sharing content across contexts. Yet we regularly use them to that end (in regulations, textbooks, memos, guidelines, laws, minutes, etc.). This paper describes the utility of the concept of a metacontext for understanding cross-contextual content-sharing with context-sensitive expressions. A metacontext is the context of a group of contexts: an infrastructure that can channel non-linguistic incentives on content ascription so as to homogenize the content ascribed to context-sensitive expressions in each context in (...) the group. Documents composed of context-sensitive expressions can share content across contexts when supported by an appropriate metacontext. The bible has its church, the textbook its education system, the form its bureaucracy, and the manifesto its social movement. Some metacontexts support cross-contextual content-sharing. Some don’t. A promising research programme (one with practical importance) would take metacontexts as its unit of analysis. (shrink)

This paper offers a defense of ‘publishing without belief’ (PWB) – the view that authors are not required to believe what they publish. I address objections to the view ranging from outright denial and advocacy of a belief norm for publication, to a modified version that allows for some cases of PWB but not others. I reject these modifications. In doing so, I offer both an alternative story about the motivations for PWB and a diagnosis of the disagreement over its (...) permissibility. The original defense focused on consequentialist reasons for allowing PWB, offering mostly defensive arguments against potential criticisms. But I argue that once we shift our focus to the reasons why authors might be prone to PWB, we see a difference in two types of motivation: whereas I imagine PWB as arising from underconfident agents, critics point to cagey or nefarious authorial practices, or authors’ failure to clarify their own degrees of belief. Underlying the debate over norms of philosophical publishing, we find two different conceptions of philosophy itself. (shrink)

The philosophical debate over disgust and its role in moral discourse has focused on disgust’s epistemic status: can disgust justify judgments of moral wrongness? Or is it misplaced in the moral domain—irrelevant at best, positively distorting at worst? Correspondingly, empirical research into disgust has focused on its role as a cause or amplifier of moral judgment, seeking to establish how and when disgust either causes us to morally condemn actions, or strengthens our pre-existing tendencies to condemn certain actions. Both of (...) these approaches to disgust are based on a set of assumptions that I call, in what follows, the evidential model of disgust. This paper proposes an alternative model, which I call the response model. Instead of looking at disgust as a cause and justification of judgments of moral wrongness, I will argue that disgust is better understood as a response to wrongness. More precisely, I argue that disgust is a response to norm violations, and that it is a fitting response insofar as norm violations are potentially contagious and therefore pose a threat to the stability and maintenance of norms.

Whether it is to be maximized or promoted as the object of a duty of beneficence, well-being is a vitally important notion in ethical theory. Well-being is a value, but to play the role it has often been assigned by ethical theory it must also be something we can measure and compare. It is a normative concept, then, but it also seems to have empirical content. Historically, philosophical conceptions of well-being have been responsive to the paired demands for normative and (...) empirical adequacy. However, recent work has yet to pay serious attention to the burgeoning field of well-being research in empirical psychology. This might be because the research is new and unknown, or it might be due to uncertainty about how a philosophical investigation would take such research into account. This chapter offers solutions to both of these problems. It provides an overview of well-being research in empirical psychology. It then uses this overview as part of an argument for an empirical informed account of well-being that we call the Value-Based Life Satisfaction Account. (shrink)

There is a correlation between positions taken on some scientific questions and political leaning. One way to explain this correlation is the cultural cognition hypothesis (CCH): people's political leanings are causing them to process evidence to maintain fixed answers to the questions, rather than to seek the truth. Another way is the different background belief hypothesis (DBBH): people of different political leanings have different background beliefs which rationalize different positions on these scientific questions. In this article, I argue for two (...) things. I argue that two attempts by proponents of the CCH to discredit the DBBH fail. And I argue that this matters, because while the CCH makes epistemic paternalistic interventions seem called for (as some philosophers have argued compellingly), the DBBH does not. The DBBH makes it much easier to stay closer to an ideal of deliberative democracy. (shrink)

Evolutionary debunking arguments draw on claims about the biological origins of our moral beliefs to undermine moral realism. In this paper, I argue that moral disagreement gives us reason to doubt the evolutionary explanations of moral judgment on which such arguments rely. The extent of cross-cultural and historical moral diversity suggests that evolution can’t explain the content of moral norms. Nor can it explain the capacity to make moral judgment in the way the debunker requires: empirical studies of folk moral (...) judgments show that they lack the kind of objectivity debunkers point to as an evolutionary contribution to our capacity for moral judgment. Thus, the empirical premise of debunking arguments lacks empirical support. (shrink)

Within the history of African American struggle against racist oppression that often verges on dystopia, a hidden tradition has depicted a transfigured world. Daring to speculate on a future beyond white supremacy, black utopian artists and thinkers offer powerful visions of ways of being that are built on radical concepts of justice and freedom. They imagine a new black citizen who would inhabit a world that soars above all existing notions of the possible. In Black Utopia, Alex Zamalin offers (...) a groundbreaking examination of African American visions of social transformation and their counterutopian counterparts. Considering figures associated with racial separatism, postracialism, anticolonialism, Pan-Africanism, and Afrofuturism, he argues that the black utopian tradition continues to challenge American political thought and culture. Black Utopia spans black nationalist visions of an ideal Africa, the fiction of W. E. B. Du Bois, and Sun Ra’s cosmic mythology of alien abduction. Zamalin casts Samuel R. Delany and Octavia E. Butler as political theorists and reflects on the antiutopian challenges of George S. Schuyler and Richard Wright. Their thought proves that utopianism, rather than being politically immature or dangerous, can invigorate political imagination. Both an inspiring intellectual history and a critique of present power relations, this book suggests that, with democracy under siege across the globe, the black utopian tradition may be our best hope for combating injustice.

Current debates in food aesthetics are moving away from a focus on whether food is art, and worries about the subjectivity and objectivity of taste, and towards questions about food's aesthetic properties, the cultural and social significance of food, our modes of aesthetic engagement with food, and issues involving cultural appropriation and the authenticity of dishes.

What can we do—and what should we do—to fight against bias? This final chapter introduces empirically-tested interventions for combating implicit (and explicit) bias and promoting a fairer world, from small daily-life debiasing tricks to larger structural interventions. Along the way, this chapter raises a range of moral, political, and strategic questions about these interventions. This chapter further stresses the importance of admitting that we don’t have all the answers. We should be humble about how much we still don’t know and (...) dedicate efforts to gathering as much knowledge as possible. Even so, we know enough now to start making a difference, and this chapter ultimately aims to chip away at the gap between our abstract commitments to treat people fairly and our lived habits and experiences, which continue to be shaped by implicit and explicit prejudices and stereotypes about race, gender, and other social categories.

A 20th anniversary edition of the art classic that celebrates the intersection of creative expression and spirituality—from one of the greatest living artists of our time Twenty years after the original publication of The Mission of Art, Alex Grey’s inspirational message affirming art’s power for personal catharsis and spiritual awakening is stronger than ever. In this special anniversary edition, Grey—visionary painter, spiritual leader, and best-selling author—combines his extensive knowledge of art history with his own experiences in creating art at (...) the boundaries of consciousness. Grey examines the roles of conscience and intention in the creative process, including practical techniques and exercises useful in exploring the spiritual dimensions of art. Challenging and thought-provoking, The Mission of Art will be appreciated by everyone who has ever contemplated the deeper purpose of creative expression. (shrink)

This paper argues that climate injustice will be compounded in the future as a result of the deferred nature of many climate impacts. My claim is that the temporal disconnect between emissions and climate harm threatens future people’s ability to access what I call “resistance goods,” which rely on forms of address, often realised in oppositional political action. I identify three resistance goods—self-assertion, solidarity and testimony—and show that each is threatened by the temporality of climate change. A compound of climate (...) injustice is that it will be experienced as demeaning, isolating and silencing by many future people. (shrink)

Speciesism, broadly understood as the view that species membership is a morally relevant property, has been a central topic of debate within animal ethics for around 50 years. However, in all this time, animal ethicists have paid relatively scant attention to the nature of species membership itself. This seems potentially regrettable, since species membership's precise nature is presumably highly pertinent to the question of its exact moral relevance. Here, I advocate for a ‘species-focused’ approach to assessing speciesism, arguing that, in (...) debating the merits of speciesism, animal ethicists should (i) centre the nature of species membership, and (ii) consult philosophers of biology. Adherence to this second prescription appears necessary since a lot of what philosophers of biology believe regarding the nature of species membership appears contrary to what many animal ethicists have seemingly assumed.

Siegel and Byrne debate whether perceptual experiences present rich properties or exclusively thin properties.

'What would happen if everyone acted that way?' This question is often used in everyday moral assessments, but it has a paradoxical quality: it draws not only on Kantian ideas of a universal moral law but also on consequentialist claims that what is right depends on the outcome. In this book, Alex Tuckness examines how the question came to be seen as paradoxical, tracing its history from the theistic approaches of the seventeenth century to the secular accounts of the (...) present. Tuckness shows that the earlier interpretations were hybrid theories that included both consequentialist and non-consequentialist elements, and argues that contemporary uses of this approach will likewise need to combine consequentialist and non-consequentialist commitments.

This chapter focuses on what’s novel in the perspective that the prediction error minimization (PEM) framework affords on the cognitive-scientific project of explaining intelligence by appeal to internal representations. It shows how truth-conditional and resemblance-based approaches to representation in generative models may be integrated. The PEM framework in cognitive science is an approach to cognition and perception centered on a simple idea: organisms represent the world by constantly predicting their own internal states. PEM theories often stress the hierarchical structure of (...) the generative models they posit. The novel explanatory power of the PEM account derives largely from the way in which pairs of generative and recognition models interact. “Predictive coding” refers to an encoding strategy in which predicted portions of an input signal are subtracted from the actual signal received, so that only the difference between the two is passed as output to the next stage of information processing.

This book offers a wide-ranging yet concise introduction to the many philosophical issues surrounding food production and consumption. It begins with discussions of the metaphysics, epistemology, and aesthetics of food, then moves on to debates about the ethics of eating animals, the environmental impacts of food production, and the role of technology in our food supply, before concluding with discussions of food access, health, and justice. Throughout, the author draws on cross-disciplinary research to engage with historical debates and current events.

The Art Experience: An Introduction to Philosophy and the Arts takes readers on an engaging and accessible journey that explores a series of fundamental questions about the nature of art and aesthetic value. Three of these questions serve as the major sections for the book's 12 chapters: What makes something a work of art? How should we experience art in order to get the most out of it? And once we understand art, how should we evaluate whether it is good (...) or bad? Philosophical theory is illustrated with concrete examples: the paintings of Frida Kahlo, the music of Johann Sebastian Bach, the masks of the Nso people, and many others. Classic questions are balanced with cutting-edge challenges, such as Linda Nochlin's work on the exclusion of women from the artistic canon. The Art Experience presupposes no prior knowledge of philosophy or art, and it will be of interest to any reader seeking an accessible and engaging introduction to this field. Along the way, readers learn how philosophical theories can affect our real-world experiences with painting, music, theater, and many more art forms. Key Features Accessible for any college student and assumes no knowledge of philosophy, art theory, or any artistic medium Organizes topics conceptually, rather than historically, allowing students to more easily grasp the core issues themselves rather than tracing their historical evolution Offers readers a large number of contemporary examples and a consistent focus on the way theory can affect people's real-world experiences with art Explores questions about bias - for example, whether the artistic canon has excluded some groups unfairly and whether definitions of art are Western-biased.

Most contemporary philosophical discussions of intentionality start and end with a treatment of the propositional attitudes. In fact, many theorists hold that all attitudes are propositional attitudes. Our folk-psychological ascriptions suggest, however, that there are non-propositional attitudes: I like Sally, my brother fears snakes, everyone loves my grandmother, and Rush Limbaugh hates Obama. I argue that things are as they appear: there are non-propositional attitudes. More specifically, I argue that there are attitudes that relate individuals to non-propositional objects and do (...) so not in virtue of relating them to propositions. I reach this conclusion by not only showing that attempted analyses of apparently non-propositional attitudes in terms of the propositional fail, but that some non-propositional attitudes don’t even supervene on propositional attitudes. If this is correct, then the common discussions of intentionality that address only propositional attitudes are incomplete and those who hold that all intentional states are propositional are mistaken.

A slew of newspaper articles were published in the 2010s with titles like: “The facts on why facts alone can’t fight false beliefs” and “Why Facts Don’t Change Our Minds — New discoveries about the human mind show the limitations of reason”. They promoted a common idea: if a person doesn’t conform to the scientific majority, it’s because she forms beliefs on scientific questions in order to achieve social goals (to fit in with people of her kind, to make her (...) social life more comfortable) instead of engaging in an earnest hunt for the truth. Rational persuasion doesn’t work with her. To change her mind, science communicators must become more paternalist. They must adopt methods of persuasion that bypass her awareness—the arts of the marketeer, the ad man. Drawing upon ideas from my recent paper, this piece aims to convince you not to take these articles so seriously. Te piece is a shortened and simplified presentation of ideas from the paper "Science Communication, Cultural Cognition, and the Pull of Epistemic Paternalism.". (shrink)

Should we understand implicit attitudes on the model of belief? I argue that implicit attitudes are (probably) members of a different psychological kind altogether, because they seem to be insensitive to the logical form of an agent’s thoughts and perceptions. A state is sensitive to logical form only if it is sensitive to the logical constituents of the content of other states (e.g., operators like negation and conditional). I explain sensitivity to logical form and argue that it is a necessary (...) condition for belief. I appeal to two areas of research that seem to show that implicit attitudes fail spectacularly to satisfy this condition—although persistent gaps in the empirical literature leave matters inconclusive. I sketch an alternative account, according to which implicit attitudes are sensitive merely to spatiotemporal relations in thought and perception, i.e., the spatial and temporal orders in which people think, see, or hear things.

Intentionalism about demonstratives is the view that the referent of a demonstrative is determined solely by the speaker's intentions. Intentionalists can disagree about the nature of these intentions, but are united in rejecting the relevance of other factors, such as the speaker's gestures, her gaze, and any facts about the addressee or the audience. In this paper, I formulate a particular version of this view, and I defend it against six objections, old and new.

How do cognition and affect interact to produce action? Research in intergroup psychology illuminates this question by investigating the relationship between stereotypes and prejudices about social groups. Yet it is now clear that many social attitudes are implicit. This raises the question: how does the distinction between cognition and affect apply to implicit mental states? An influential view—roughly analogous to a Humean theory of action—is that “implicit stereotypes” and “implicit prejudices” constitute two separate constructs, reflecting different mental processes and neural (...) systems. On this basis, some have also argued that interventions to reduce discrimination should combat implicit stereotypes and prejudices separately. We propose an alternative framework. We argue that all putative implicit stereotypes are affect-laden and all putative implicit prejudices are “semantic,” that is, they stand in co-activating associations with concepts and beliefs. Implicit biases, therefore, consist in “clusters” of semantic-affective associations, which differ in degree, rather than kind. This framework captures the psychological structure of implicit bias, promises to improve the power of indirect measures to predict behavior, and points toward the design of more effective interventions to combat discrimination.

Citizenship issues are in the vanguard of the democratization process of the European Union. As a result, much academic debate has centred on the significance, worth, and potential of the status of European Union citizen bestowed on all member state nationals by the Maastricht Treaty. This article traces the growing debate on ‘European’ citizenship in the form of a literature review. It places the debate in the context of the EU's own evolution and argues that citizenship, whether broadly or narrowly (...) conceived, is currently in a frozen condition, since it was one of the major issues whose discussion was postponed by the member governments at the Amsterdam summit of 1997. Nonetheless, the creation of the status of EU citizen has unleashed expectations of greater inclusivity in decision making which the EU cannot afford to ignore if the democratization process is to continue. The likely result is an experiment in post‐national citizenship based on a multilevel Europolity and the separation of ethnic and political memberships. (shrink)

In this paper, we consider how certain longstanding philosophical questions about mental representation may be answered on the assumption that cognitive and perceptual systems implement hierarchical generative models, such as those discussed within the prediction error minimization framework. We build on existing treatments of representation via structural resemblance, such as those in Gładziejewski :559–582, 2016) and Gładziejewski and Miłkowski, to argue for a representationalist interpretation of the PEM framework. We further motivate the proposed approach to content by arguing that it (...) is consistent with approaches implicit in theories of unsupervised learning in neural networks. In the course of this discussion, we argue that the structural representation proposal, properly understood, has more in common with functional-role than with causal/informational or teleosemantic theories. In the remainder of the paper, we describe the PEM framework for approximate Bayesian inference in some detail, and discuss how structural representations might arise within the proposed Bayesian hierarchies. After explicating the notion of variational inference, we define a subjectively accessible measure of misrepresentation for hierarchical Bayesian networks by appeal to the Kullbach–Leibler divergence between posterior generative and approximate recognition densities, and discuss a related measure of objective misrepresentation in terms of correspondence with the facts.

Contemporary process metaphysics has achieved a number of important results, most significantly in accounting for emergence, a problem on which substance metaphysics has foundered since Plato. It also faces trenchant problems of its own, among them the related problems of boundaries and individuation. Historically, the quest for ontology may thus have been largely responsible for the persistence of substance metaphysics. But as Plato was well aware, an ontology of substantial things raises serious, perhaps insurmountable problems for any account of our (...) epistemic access to such things. Physical things are subject to change, and as such, they are poor objects of knowledge—if knowledge is to be more reliable than mere opinion. There is a reading of Plato’s Theaetetus on which knowledge may be understood as a relation between an epistemic subject and a logos, where logoi are intrinsically dialectical, and where dialectic is a kind of intersubjective activity. Insofar as this epistemology may be attributed to Plato, the project of this paper is Platonic in spirit. It is also, in a sense, Kantian, in that it divorces ontology from the search for things-in-themselves, redirecting our attention from things to objects: epistemic objects. Such objects can be understood, as Maurice Merleau-Ponty proposed, as shared by multiple subjects by virtue of their participation in an intersubjective world, constituted by what Shaun Gallagher calls ‘‘participatory sense-making.’’ On an epistemology constructed in this way, the fact that both epistemic objects and their subject are mutable is no obstacle to knowledge. Far-from-equilibrium systems are forever mutable; at thermodynamic equilibrium, there would be neither subject, nor object. Epistemic objects, on this picture, are metastable loci of interactive potential. (shrink)
