The Uniqueness Thesis holds, roughly speaking, that there is a unique rational response to any particular body of evidence. We first sketch some varieties of Uniqueness that appear in the literature. We then discuss some popular views that conflict with Uniqueness and others that require Uniqueness to be true. We then examine some arguments that have been presented in its favor and discuss why permissivists find them unconvincing. Last, we present some purported counterexamples that have been raised against Uniqueness and (...) discuss some possible reasons why proponents of Uniqueness might find these similarly unconvincing.

The knowledge account of assertion holds that it is improper to assert that p unless the speaker knows that p. This paper argues against the knowledge account of assertion; there is no general norm that the speaker must know what she asserts. I argue that there are cases in which it can be entirely proper to assert something that you do not know. In addition, it is possible to explain the cases that motivate the knowledge account by postulating a general (...) norm that assertions would be true, combined with conversational norms that govern all speech acts. A theory on which proper assertions must be true explains the data better than a theory on which proper assertions must be known to be true. (shrink)

One hypothesis concerning the human dorsal anterior cingulate cortex (ACC) is that it functions, in part, to signal the occurrence of conflicts in information processing, thereby triggering compensatory adjustments in cognitive control. Since this idea was first proposed, a great deal of relevant empirical evidence has accrued. This evidence has largely corroborated the conflict-monitoring hypothesis, and some very recent work has provided striking new support for the theory. At the same time, other findings have posed specific challenges, especially concerning the (...) way the theory addresses the processing of errors. Recent research has also begun to shed light on the larger function of the ACC, suggesting some new possibilities concerning how conflict monitoring might fit into the cingulate's overall role in cognition and action.

Surprisingly little has been written about hedged assertion. Linguists often focus on semantic or syntactic theorizing about, for example, grammatical evidentials or epistemic modals, but pay far less attention to what hedging does at the level of action. By contrast, philosophers have focused extensively on normative issues regarding what epistemic position is required for proper assertion, yet they have almost exclusively considered unqualified declaratives. This essay considers the linguistic and normative issues side-by-side. We aim to bring some order and clarity (...) to thinking about hedging, so as to illuminate aspects of interest to both linguists and philosophers. In particular, we consider three broad questions. 1) The structural question: when one hedges, what is the speaker’s commitment weakened from? 2) The functional question: what is the best way to understand how a hedge weakens? And 3) the taxonomic question: are hedged assertions genuine assertions, another speech act, or what? (shrink)

I argue that a variety of influential accounts of self-knowledge are flawed by the assumption that all immediate, authoritative knowledge of our own present mental states is of one basic kind. I claim, on the contrary, that a satisfactory account of self-knowledge must recognize at least two fundamentally different kinds of self-knowledge: an active kind through which we know our own judgments, and a passive kind through which we know our sensations. I show that the former kind of self-knowledge is (...) in an important sense fundamental, since it is intimately connected with the very capacity for rational reflection, and since it must be present in any creature that understands the first-person pronoun. Moreover, I suggest that these thoughts about self-knowledge have a Kantian provenance. (shrink)

This book addresses a range of relevant theoretical issues, including the possibility of an interpersonally comparable measure of well-being, or “utility” metric; the moral value of equality, and how that bears on the form of the social welfare function; social choice under uncertainty; and the possibility of integrating considerations of individual choice and responsibility into the social-welfare-function framework. This book also deals with issues of implementation, and explores how survey data and other sources of evidence might be used to calibrate (...) both a utility metric and a social welfare function, and whether distributive goals are ever best pursued through regulation rather than the tax system. In working through this range of theoretical and practical issues, the book draws from a wide variety of literatures, including philosophical scholarship on equality, responsibility, the nature of well-being, and personal identity over time; the social choice literature within economics; applied economic literatures concerning the measurement of inequality and poverty; legal and policy-analysis scholarship on cost-benefit analysis, environmental justice, and the choice between regulation and taxation; and the burgeoning field of “happiness studies”.

Combining philosophy of art with film criticism, Strohl flips conventional notions of good and bad on their heads and makes the case that the ultimate value of a work of art lies in what it can add to our lives. By this measure, some of the worst movies ever made are also among the best.

The Identity principle says that conditionals with the form 'If p, then p' are logical truths. Identity is overwhelmingly plausible, and has rarely been explicitly challenged. But a wide range of conditionals nonetheless invalidate it. I explain the problem, and argue that the culprit is the principle known as Import-Export, which we must thus reject. I then explore how we can reject Import-Export in a way that still makes sense of the intuitions that support it, arguing that the differences between (...) indicative and subjunctive conditionals play a key role in solving this puzzle.

When an abortion is performed, someone dies. Are we killing a human person? Widespread disagreement exists. However, it is not necessary to establish personhood in order to establish the wrongness of abortion: a substantial chance of personhood is enough. We defend The Do Not Risk Homicide Argument: abortions are wrong after 10 weeks gestation because they substantially and unjustifiably risk homicide, the unjust killing of a human person. Why 10 weeks? Because the cumulative evidence establishes a substantial chance (a more (...) than one in five chance) that preborn human beings are persons after 10 weeks (if not before then). We submit evidence from our bad track record, widespread disagreement about personhood (after 10 weeks gestation), problems with theories of personhood, the similarity between preborn human beings and premature newborns, miscalculations of gestational age, and the common intuitive responses of women to their pregnancies and miscarriages. Our argument is cogent because it bypasses the stalemate over preborn personhood and rests on common ground rather than contentious metaphysics. It also strongly suggests that society must do more to protect preborn human beings. We briefly discuss its practical implications for fetal pain relief, social policy, and abortion law. (shrink)

This paper addresses the “creeping minimalism” challenge to quasi-realist forms of expressivism by arguing that the solution suggested by Dreier doesn’t work and proposing an alternative solution based on the different inferential roles of ethical and descriptive judgments.

This essay updates Aaron Smuts', 2009 Philosophy Compass piece, “Art and Negative Affect” in light of recent work on the topic. The “paradox of painful art” is the general problem of how it is possible to enjoy or value experiences of art that involve painful emotions. It encompasses both the paradox of tragedy and the paradox of horror. Section 2 lays out a taxonomy of solutions to the paradox of painful art and argues that we should opt for a pluralistic (...) approach rather than seeking a unified solution. Section 3 surveys recent work on the topic, with an emphasis on views holding that it is possible for an experience of art to be pleasant partly in virtue of involving painful emotion. Section 4 suggests a range of phenomena that are not usually considered under the umbrella of the paradox of painful art but that offer promising directions for further research. (shrink)

In this paper, I make explicit some implicit commitments to realism and conceptualism in recent work in social epistemology exemplified by Miranda Fricker and Charles Mills. I offer a survey of recent writings at the intersection of social epistemology, feminism, and critical race theory, showing that commitments to realism and conceptualism are at once implied yet undertheorized in the existing literature. I go on to offer an explicit defense of these commitments by drawing from the epistemological framework of John McDowell, (...) demonstrating the relevance of the metaphor of the “space of reasons” for theorizing and criticizing instances of epistemic injustice. I then point out how McDowell’s own view requires expansion and revision in light of Mills' concept of 'epistemologies of ignorance'. I conclude that, when their strengths are used to make up for each others' weaknesses, Mills and McDowell’s positions mutually reinforce one another, producing a powerful model for theorizing instances of systematic ignorance and false belief.

Do the cognitive origins of our theistic beliefs debunk them or explain them away? This paper develops an empirically-motivated debunking argument and defends it against objections. First, we introduce the empirical and epistemological background. Second, we develop and defend the main argument, the debunking argument from false god beliefs. Third, we characterize and evaluate the most prominent religious debunking argument to date, the debunking argument from insensitivity. It is found that insensitivity-based arguments are problematic, which makes them less promising than (...) the debunking argument from false god beliefs. (shrink)

In the recent history of psychology and cognitive neuroscience, the notion of habit has been reduced to a stimulus-triggered response probability correlation. In this paper we use a computational model to present an alternative theoretical view (with some philosophical implications), where habits are seen as self-maintaining patterns of behavior that share properties in common with self-maintaining biological processes, and that inhabit a complex ecological context, including the presence and influence of other habits. Far from mechanical automatisms, this organismic and self-organizing (...) concept of habit can overcome the dominating atomistic and statistical conceptions, and the high temporal resolution effects of situatedness, embodiment and sensorimotor loops emerge as playing a more central, subtle and complex role in the organization of behavior. The model is based on a novel “iterant deformable sensorimotor medium” (IDSM), designed such that trajectories taken through sensorimotor-space increase the likelihood that in the future, similar trajectories will be taken. We couple the IDSM to sensors and motors of a simulated body and environment and show that under certain conditions, the IDSM forms self-maintaining patterns of activity that operate across the IDSM, the body, and the environment. We present various environments and the resulting habits that form in them. The model acts as an abstraction of habits at a much needed sensorimotor “meso-scale” between microscopic neuron-based models and macroscopic descriptions of behavior. Finally, we discuss how this model and extensions of it can help us understand aspects of behavioral self-organization, historicity and autonomy that remain out of the scope of contemporary representationalist frameworks.

Game theorists tend to model climate negotiations as a so-called ‘tragedy of the commons’. This is rather worrisome, since the conditions under which such commons problems have historically been solved are almost entirely absent in the case of international greenhouse gas emissions. In this paper, I will argue that the predictive accuracy of the tragedy model might not stem from the model’s inherent match with reality but rather from the model’s ability to make self-fulfilling predictions. I then sketch some possible (...) ways to dispel the tragedy, including (1) recognizing some ways the assumptions of the model fail, (2) taking seriously recent work suggesting that increasing greenhouse gas emissions is not in most nations’ own self-interest, and (3) preferring alternative models like collective risk dilemmas, bargaining games, or cooperative models.

Over the past few decades, significant advances have been made in public engagement with, and the democratization of, science and technology. Despite notable successes, such developments have often struggled to enhance public trust, avert crises of expertise and democracy, and build more socially responsive and responsible science and innovation. A central reason for this is that mainstream approaches to public engagement harbor what we call “residual realist” assumptions about participation and publics. Recent coproductionist accounts in science and technology studies offer (...) an alternative way of seeing participation as coproduced, relational, diverse, and emergent but have been somewhat reluctant to articulate what this means in practice. In this paper, we make this move by setting out a new framework of interrelating paths and associated criteria for remaking public participation with science and democracy in more experimental, reflexive, anticipatory, and responsible ways. This framework comprises four paths to: forge reflexive participatory practices that attend to their framings, emergence, uncertainties, and effects; ecologize participation through attending to the interrelations between diverse public engagements in wider systems; catalyze practices of anticipatory reflection to bring about responsible democratic innovations; and reconstitute participation as constitutive of systems of technoscience and democracy.

Based on a framework that integrates job demands-resources theory, social cognitive theory Handbook of personality, Guilford Press, New York, pp 154–196, 1999) and regulatory focus theory, the purpose of this research is to investigate the relationship between perceptions of organizational politics and subsequent moral disengagement and unethical behavior. We conducted a laboratory study and also collected data in two separate surveys 6 weeks apart from 206 individuals working full time to investigate the relationships presented in our model. In both studies, (...) we examined the direct relationship of politics perceptions on unethical behavior in organizations as well as the indirect relationship through the influence of moral disengagement. We investigated the moderating effect of regulatory focus on the relationship between moral disengagement and unethical behavior using the survey data. Results indicated that perceptions of politics were significantly related to our mediator, moral disengagement, which was significantly related to our dependent variable, unethical behavior. However, only prevention-focus moderated the relationships examined. Implications for future research and managerial practice are discussed. (shrink)

Sadness is generally seen as a negative emotion, a response to distressing and adverse situations. In an aesthetic context, however, sadness is often associated with some degree of pleasure, as suggested by the ubiquity and popularity, throughout history, of music, plays, films and paintings with a sad content. Here, we focus on the fact that music regarded as sad is often experienced as pleasurable. Compared to other art forms, music has an exceptional ability to evoke a wide-range of feelings and (...) is especially beguiling when it deals with grief and sorrow. Why is it, then, that while human survival depends on preventing painful experiences, mental pain often turns out to be explicitly sought through music? In this article we consider why and how sad music can become pleasurable. We offer a framework to account for how listening to sad music can lead to positive feelings, contending that this effect hinges on correcting an ongoing homeostatic imbalance. Sadness evoked by music is found pleasurable (1) when it is perceived as non-threatening; (2) when it is aesthetically pleasing; and (3) when it produces psychological benefits such as mood regulation, and empathic feelings, caused, for example, by recollection of and reflection on past events. We also review neuroimaging studies related to music and emotion and focus on those that deal with sadness. Further exploration of the neural mechanisms through which stimuli that usually produce sadness can induce a positive affective state could help the development of effective therapies for disorders such as depression, in which the ability to experience pleasure is attenuated.

Should we remain neutral between our interests and those of future generations? Or are we ethically permitted or even required to depart from neutrality and engage in some measure of intergenerational discounting? This Article addresses the problem of intergenerational discounting by drawing on two different intellectual traditions: the social welfare function (“SWF”) tradition in welfare economics, and scholarship on “prioritarianism” in moral philosophy. Unlike utilitarians, prioritarians are sensitive to the distribution of well-being. They give greater weight to well-being changes affecting (...) worse-off individuals. Prioritarianism can be captured, formally, through an SWF which sums a concave transformation of individual utility, rather than simply summing unweighted utilities in utilitarian fashion. The Article considers the appropriate structure of a prioritarian SWF in intergenerational cases. The simplest case involves a fixed and finite intertemporal population. In that case, I argue, policymakers can and should maintain full neutrality between present and future generations. No discount factor should be attached to the utility of future individuals. Neutrality becomes trickier when we depart from this simple case, meaning: (1) “non-identity” problems, where current choices change the identity of future individuals; (2) population-size variation, where current choices affect not merely the identity of future individuals, but the size of the world’s future population (this case raises the specter of what Derek Parfit terms “the repugnant conclusion,” i.e., that dramatic reductions in the average level of individual well-being might be compensated for by increases in population size); or (3) an infinite population. The Article grapples with the difficult question of outfitting a prioritarian SWF to handle non-identity problems, population-size variation, and infinite populations. It tentatively suggests that a measure of neutrality can be maintained even in these cases. (shrink)

This paper addresses the relationships between hope and trust. I suggest that different kinds of hope and trust relate to one another in different ways, which I conceive of in dynamic terms. I propose that the movement of hope and trust has a unifying context: the changing structure of a human life and its dependence on other people. I further argue that the most fundamental forms of hope and trust are inextricable. Together, they comprise a diffuse way of anticipating things (...) in general, which could equally be described in terms of “faith.” This sustains a life structure upon which more specific forms of hope and trust depend.

Evolutionary debunking arguments, notably Sharon Street’s Darwinian Dilemma (2006), allege that moral realists need to explain the reliability of our moral judgments, given their evolutionary sources. David Copp (2008) and David Enoch (2010) take up the challenge. I argue on empirical grounds that realists have not met the challenge and moreover cannot do so. The outcome is that there are empirically-motivated reasons for thinking moral realists cannot explain moral reliability, given our current empirical understanding.

Pluralisms of various sorts are popular in philosophy of science, including those that imply some scientific concept x should be eliminated from science in favour of a plurality of concepts x1, x2, … xn.

I spell out and update the individuality thesis, that species are individuals, and not classes, sets, or kinds. I offer three complementary presentations of this thesis. First, as a way of resolving an inconsistent triad about natural kinds; second, as a phylogenetic systematics theoretical perspective; and, finally, as a novel recursive account of an evolved character. These approaches do different sorts of work, serving different interests. Presenting them together produces a taxonomy of the debates over the thesis, and isolates ways (...) it has been productive. This goes to the larger point of this paper: a defense of the individuality thesis in terms of its utility, and an update of it in light of recent theoretical developments and empirical work in biology.

We investigated whether mathematicians typically agree about the qualities of mathematical proofs. Between-mathematician consensus in proof appraisals is an implicit assumption of many arguments made by philosophers of mathematics, but to our knowledge the issue has not previously been empirically investigated. We asked a group of mathematicians to assess a specific proof on four dimensions, using the framework identified by Inglis and Aberdein (2015). We found widespread disagreement between our participants about the aesthetics, intricacy, precision and utility of the proof, (...) suggesting that a priori assumptions about the consistency of mathematical proof appraisals are unreasonable.

Why does art matter to us, and what makes it good? Why is the role of imagination so important in art? Illustrated with carefully chosen colour and black-and-white plates of examples from Michaelangelo to Matisse and Poussin to Pollock, _Revealing Art_ takes us on a compelling and provocative journey. Kieran explores some of the most important questions we can ask ourselves about art: how can art inspire us or disgust us? Is artistic judgement simply a matter of taste? Can art (...) be immoral or obscene, and should it be censored? He brings such abstract issues to life with fascinating discussions of individual paintings, photographs and sculptures, such as Michelangelo's _Pieta_, Andres Serrano's _Piss Christ_ and Francis Bacon's powerful paintings of the Pope. He also suggests some answers to problems that any one in an art gallery or museum is likely to ask themselves: what is a beautiful work of art? and can art really reveal something true about our own nature? _Revealing Art _is ideal for anyone interested in debates about art today, or who has simply stood in front of a painting and felt baffled.

In ‘Computing Machinery and Intelligence’, Turing, sceptical of the question ‘Can machines think?’, quickly replaces it with an experimentally verifiable test: the imitation game. I suggest that for such a move to be successful the test needs to be relevant, expansive, solvable by exemplars, unpredictable, and lead to actionable research. The Imitation Game is only partially successful in this regard and its reliance on language, whilst insightful for partially solving the problem, has put AI progress on the wrong foot, prescribing (...) a top-down approach for building thinking machines. I argue that to fix shortcomings with modern AI systems a nonverbal operationalisation is required. This is provided by the recent Animal-AI Testbed, which translates animal cognition tests for AI and provides a bottom-up research pathway for building thinking machines that create predictive models of their environment from sensory input.

This essay addresses the question of when evidence for a stronger claim H1 also constitutes evidence for a weaker claim H2. Although the answer “Always” is tempting, it is false on a natural Bayesian conception of evidence. This essay first describes some prima facie counterexamples to this answer and surveys some weaker answers and rejects them. Next, it proposes an answer, which appeals to the “Dragging Condition.” After explaining and arguing for its use of the Dragging Condition, the essay argues (...) that the Dragging Condition provides a general account of, and solution to, the counterexamples with which the essay began. The essay briefly discusses the relevance of the Dragging Condition to the recently much-discussed topic of “transmission failure” in epistemology, applies the Dragging Condition to the problem of “bootstrapping” in epistemology, and discusses three important objections to the view defended in the essay.

Dogged resistance to demanding moral views frequently takes the form of The Demandingness Objection. Premise (1): Moral view V demands too much of us. Premise (2): If a moral view demands too much of us, then it is mistaken. Conclusion: Therefore, moral view V is mistaken. Objections of this form harass major theories in normative ethics as well as prominent moral views in applied ethics and political philosophy. The present paper does the following: (i) it clarifies and distinguishes between various (...) demandingness objections in the philosophical literature, (ii) identifies a formidable and interesting form of the demandingness objection that targets a wide scope of moral views, and (iii) defuses this objection by developing a local skeptical argument from unreliability the form of which may, interestingly, be effectively deployed in other areas of philosophy.

People maintain a positive identity in at least two ways: They evaluate themselves more favorably than other people, and they judge themselves to be better now than they were in the past. Both strategies rely on autobiographical memories. The authors investigate the role of autobiographical memories of lying and emotional harm in maintaining a positive identity. For memories of lying to or emotionally harming others, participants judge their own actions as less morally wrong and less negative than those in which (...) other people lied to or emotionally harmed them. Furthermore, people judge those actions that happened further in the past to be more morally wrong than those that happened more recently. Finally, for periods of the past when they believed that they were very different people than they are now, participants judge their actions to be more morally wrong and more negative than those actions from periods of their pasts when they believed that they were very similar to who they are now. The authors discuss these findings in relation to theories about the function of autobiographical memory and moral cognition in constructing and perceiving the self over time. (shrink)

This paper initiates analytic inquiry into the metaphysics of masculinity. I argue that individual masculinities (such as ‘clone masculinity’ and ‘incel masculinity’) are distinct homeostatic property cluster kinds related to gender structures via processes of adherence, failed-adherence, selective adherence, and/or reinterpretation with respect to male-coded social norms.

This paper explores the phenomenology of touch and proposes that the structure of touch serves to cast light on the more general way in which we 'find ourselves in a world'. Recent philosophical work on perception tends to emphasize vision. This, I suggest, motivates the imposition of a distinction between externally directed perception of objects and internally directed perception of one's own body. In contrast, the phenomenology of touch involves neither firm boundaries between body and world nor perception of bodily (...) states in isolation from perception of everything else. I begin by arguing that touch does not involve two distinct feelings, a feeling of the body and a feeling of something external to the body. Rather, these are inextricable aspects of the same unitary experience, with one or the other occupying the experiential foreground. Then I suggest that tactile experience does not always respect a clear boundary between body and world. In touch, bodily and worldly aspects are experienced in a number of different ways and, in many instances, there is no clear experiential differentiation between the two. Finally, I draw these two points together in order to consider the contribution made by touch to our sense of being situated in a world. (shrink)

The emergence of signaling systems has been observed in numerous experimental and real-world contexts, but there is no consensus on which shared mechanisms underlie such phenomena. A number of explanatory mechanisms have been proposed within several disciplines, all of which have been instantiated as credible working models. However, they are usually framed as being mutually incompatible. Using an exemplar-based framework, we replicate these models in a minimal configuration which allows us to directly compare them. This reveals that the development of (...) optimal signaling is driven by similar mechanisms in each model, which leads us to propose three requirements for the emergence of conventional signaling. These are the creation and transmission of referential information, a systemic bias against ambiguity, and finally some form of information loss. Considering this, we then discuss some implications for theoretical and experimental approaches to the emergence of learned communication. (shrink)

In order for the concept, 'recognition', to play a critical role in social theory, it must be possible to draw a distinction between due recognition and failures of recognition. Some recognition theorists, including Axel Honneth, argue that this distinction can be preserved only if we presuppose that due recognition involves a rational response to "evaluative qualities" that can be rightly perceived in the context of social interaction. This paper points out a problem facing recent defenses of this "perception model" and (...) proposes a solution. I begin by making explicit three criteria broadly shared by recognition theorists: an adequate theory of recognition must be (a) critical, capable of drawing a distinction between due recognition and recognitive failure; (b) minimally idealist, able to accommodate the mediating role of subjectivity in human receptivity to value; and (c) historicist, should not rule out a priori that the values involved in recognitive practice are historically emergent. I then argue that Honneth's version of the perception model cannot fulfill these criteria simultaneously. Drawing upon an Aristotelian notion of evaluative perception and working through an example from Zadie Smith's On Beauty, I defend an alternative view that is, I argue, better equipped to meet these three criteria.

The goal of this two-part series of papers is to show that constructive logic with strong negation N is definitionally equivalent to a certain axiomatic extension NFL ew of the substructural logic FL ew .

The main result of this paper is exploited in Part II of this series [40] to show that the deductive systems N and NFL ew are definitionally equivalent, and hence that constructive logic with strong negation is a substructural logic over FL ew.

Lewisian theism is the view that both traditional theism and Lewis’s modal realism are true. On Lewisian theism, God must exist in worlds in one of the following ways: God can be said to have a counterpart in each world; God can be said to exist in each world in the way that a universal can be said to exist in worlds, i.e. through transworld identity; God can be said to be a scattered individual, with a part of God existing (...) in each world; and, God can be said to exist in each world, through His existing from the standpoint of each world. In the literature, – have been rejected as viable options. I grant that and are not viable. However, I believe that and have been too hastily rejected. Herein, I develop ways to respond to objections to and, and conclude that is a viable option for Lewisian theists. (shrink)

Although there once was a general consensus among race scholars that applying race categories to humans is biologically illegitimate, this consensus has been erased over the past decade. This is largely due to advances in population genetics that allow biologists to pick out genetic population clusters that approximate some of our common sense racial categories. In this paper, I argue that this new ability really ought not undermine our confidence in the biological illegitimacy of the human races. Unfortunately, the claim (...) that races are biologically legitimate is ambiguous—the sense I will be concerned with here holds that the human species can be divided into biological subspecies. Sesardic and Andreasen have both argued that the cluster results are evidence for subspecies within the human population. I show the cluster results are in fact evidentially inert relative to each author’s preferred subspecies concept. I then sketch the kinds of biological facts that could be used to adjudicate whether human subspecies have existed in the past. (shrink)
