This paper examines both creepiness and the distinctive reaction had to creepiness, being “creeped out.” The paper defends a response-dependent account of creepiness in terms of this distinctive reaction, contrasting our preferred account to others that might be offered. The paper concludes with a discussion of the value of detecting creepiness.

Moral debunking arguments are meant to show that, by realist lights, moral beliefs are not explained by moral facts, which in turn is meant to show that they lack some significant counterfactual connection to the moral facts (e.g., safety, sensitivity, reliability). The dominant, “minimalist” response to the arguments—sometimes defended under the heading of “third-factors” or “pre-established harmonies”—involves affirming that moral beliefs enjoy the relevant counterfactual connection while granting that these beliefs are not explained by the moral facts. We show that (...) the minimalist gambit rests on a controversial thesis about epistemic priority: that explanatory concessions derive their epistemic import from what they reveal about counterfactual connections. We then challenge this epistemic priority thesis, which undermines the minimalist response to debunking arguments (in ethics and elsewhere). (shrink)

Public discussions of political and social issues are often characterized by deep and persistent polarization. In social psychology, it’s standard to treat belief polarization as the product of epistemic irrationality. In contrast, we argue that the persistent disagreement that grounds political and social polarization can be produced by epistemically rational agents, when those agents have limited cognitive resources. Using an agent-based model of group deliberation, we show that groups of deliberating agents using coherence-based strategies for managing their limited resources tend (...) to polarize into different subgroups. We argue that using that strategy is epistemically rational for limited agents. So even though group polarization looks like it must be the product of human irrationality, polarization can be the result of fully rational deliberation with natural human limitations. (shrink)

Evolutionary debunking arguments abound, but it is widely assumed that they do not arise for our perceptual beliefs about midsized objects, insofar as the adaptive value of our object beliefs cannot be explained without reference to the objects themselves. I argue that this is a mistake. Just as with moral beliefs, the adaptive value of our object beliefs can be explained without assuming that the beliefs are accurate. I then explore the prospects for other sorts of vindications of our object (...) beliefs—which involve “bootstrapping” from our experiences as of midsized objects—and I defend bootstrapping maneuvers against a variety of objections. Finally, I argue for an explanatory constraint on legitimate bootstrapping and show how some attempts to respond to debunking arguments run afoul of the constraint. (shrink)

Value pluralists believe in multiple dimensions of value. What does betterness along a dimension have to do with being better overall? Any systematic answer begins with the Strong Pareto principle: one thing is overall better than another if it is better along one dimension and at least as good along all others. We defend Strong Pareto from recent counterexamples and use our discussion to develop a novel view of dimensions of value, one which puts Strong Pareto on firmer footing. We (...) conclude by defending Dimensionalism, the hypothesis that overall value relations are determined solely by how things compare along value dimensions. These are first steps towards a more systematic value pluralism. (shrink)

It is commonly said that some standards, such as morality, are ‘normatively authoritative’ in a way that other standards, such as etiquette, are not; standards like etiquette are said to be ‘not really normative’. Skeptics deny the very possibility of normative authority, and take claims like ‘etiquette is not really normative’ to be either empty or confused. I offer a different route to defeat skeptics about authority: instead of focusing on what makes standards like morality special, we should focus on (...) what makes standards like etiquette ‘not really normative’. I defend a fictionalist theory on which etiquette is ‘not really normative’ in roughly the same way that Sherlock is ‘not really a detective’, and show that fictionalism about some normative standards helps us explain the possibility of normative authority.

Conversational exculpature is a pragmatic process whereby information is subtracted from, rather than added to, what the speaker literally says. This pragmatic content subtraction explains why we can say “Rob is six feet tall” without implying that Rob is between 5'0.99" and 6'0.01" tall, and why we can say “Ellen has a hat like the one Sherlock Holmes always wears” without implying Holmes exists or has a hat. This article presents a simple formalism for understanding this pragmatic mechanism, specifying how, (...) in context, the result of such subtractions is determined. And it shows how the resulting theory of conversational exculpature accounts for a varied range of linguistic phenomena. A distinctive feature of the approach is the crucial role played by the question under discussion in determining the result of a given exculpature. (shrink)

This paper argues for several related theses. First, the epistemological position that knowledge requires safe belief can be motivated by views in the philosophy of science, according to which good explanations show that their explananda are robust. This motivation goes via the idea—recently defended on both conceptual and empirical grounds—that knowledge attributions play a crucial role in explaining successful action. Second, motivating the safety requirement in this way creates a choice point—depending on how we understand robustness, we'll end up with (...) different conceptions of safety in epistemology. Lastly, and most controversially, there's an attractive choice at this point that will not vindicate some of the most influential applications of the safety-theoretic framework in epistemology, e.g., Williamson's arguments against the KK principle, and luminosity.

It is commonly argued that a serious right to life is grounded only in actual, relatively advanced psychological capacities a being has acquired. The moral permissibility of abortion is frequently argued for on these grounds. Increasingly it is being argued that such accounts also entail the permissibility of infanticide, with several proponents of these theories accepting this consequence. We show, however, that these accounts imply the permissibility of even more unpalatable acts than infanticide performed on infants: organ harvesting, live experimentation, (...) sexual interference, and discriminatory killing. The stronger intuitions against the permissibility of these ‘pre-personal acts’ allow us to re-establish a comprehensive and persuasive reductio against psychological accounts of persons. (shrink)

We defend a functionalist approach to emotion that begins by focusing on emotions as central states with causal connections to behavior and to other cognitive states. The approach brackets the conscious experience of emotion, lists plausible features that emotions exhibit, and argues that alternative schemes are unpromising candidates. We conclude with the benefits of our approach: one can study emotions in animals; one can look in the brain for the implementation of specific features; and one ends up with an architecture (...) of the mind in which emotions are fully accommodated through their relations to the rest of cognition. Our article focuses on arguing for this general approach; as such, it is an essay in the philosophy of emotion rather than in the psychology or neuroscience of emotion. (shrink)

Well-being measurements are frequently used to support conclusions about a range of philosophically important issues. This is a problem, because we know too little about the intervals of the relevant scales. I argue that it is plausible that well-being measurements are non-linear, and that common beliefs that they are linear are not truth-tracking, so we are not justified in believing that well-being scales are linear. I then argue that this undermines common appeals to both hypothetical and actual well-being measurements; I (...) first focus on the philosophical literature on prioritarianism and then discuss Kahneman’s Peak-End Rule as a systematic bias. Finally, I discuss general implications for research on well-being, and suggest a better way of representing scales. (shrink)

While those who take a "structuralist" approach to racial justice issues are right to call attention to the importance of social practices, laws, etc., they sometimes go too far by suggesting that antiracist efforts ought to focus on changing unjust social systems rather than changing individuals’ minds. We argue that while the “either/or” thinking implied by this framing is intuitive and pervasive, it is misleading and self-undermining. We instead advocate for a “both/and” approach to antiracist moral education that explicitly teaches (...) how social structures influence ideas about race and how ideas about race shape, sustain, and transform social structures. Ideally, antiracist moral education will help people see how social change and moral progress depend on the symbiotic relations between individuals and structures. We articulate a conception of “structure-facing virtue” that exemplifies this hybrid approach to illuminate the pivotal role moral education plays in the fight for racial justice. (shrink)

There is good reason to think that, in every case of perceptual consciousness, there is something of which we are conscious; but there is also good reason to think that, in some cases of perceptual consciousness—for instance, hallucinations—there is nothing of which we are conscious. This paper resolves this inconsistency—which we call the presentation problem—by (a) arguing that ‘conscious of’ and related expressions function as intensional transitive verbs and (b) defending a particular semantic approach to such verbs, on which they (...) have readings that lack direct objects or themes. The paper further argues that this approach serves not only as a linguistic proposal about the semantics of ‘conscious of’, but also as a proposal about the metaphysics of conscious states. (shrink)

The U.S. election in November 2016 raised and amplified doubts about first-past-the-post (“plurality rule”) electoral systems. Arguments against plurality rule and for alternatives like preferential voting tend to be consequentialist: it is argued that systems like preferential voting produce different, better outcomes. After briefly noting why the consequentialist case against plurality rule is more complex and contentious than it first appears, I offer an expressive alternative: plurality rule produces actual or apparent dilemmas for voters in ways that are morally objectionable, (...) and avoidable under preferential voting systems. This expressive case against plurality rule is both simpler and more ecumenical than its consequentialist counterpart, and it provides strong reasons to prefer alternatives to plurality rule. Moreover, it suggests a distinct way of evaluating different alternatives like preferential voting. (shrink)

Kripke’s Wittgenstein is standardly understood as a non-factualist about meaning ascription. Non-factualism about meaning ascription is the idea that sentences like “Joe means addition by ‘plus’” are not used to state facts about the world. Byrne and Kusch have argued that Kripke’s Wittgenstein is not a non-factualist about meaning ascription. They are aware that their interpretation is non-standard, but cite arguments from Boghossian and Wright to support their view. Boghossian argues that non-factualism about meaning ascription is incompatible with a deflationary (...) theory of truth. Wright argues that non-factualism about meaning ascription is incoherent. To support the standard interpretation, I’ll respond to each argument in turn. To the degree that my responses are successful, Byrne and Kusch have an unmotivated interpretation of Kripke’s Wittgenstein. Wilson provides a factualist interpretation that is not based on Boghossian and Wright’s arguments. Miller argues for a non-factualist interpretation against Wilson, but I’ll show that Miller’s interpretation faces a dilemma. Miller’s argument cannot be maintained if a coherent interpretation of the skeptical solution is to be provided. I’ll show how this dilemma can be avoided and provide an independent argument against Wilson so that a non-factualist interpretation of the skeptical solution can be maintained. (shrink)

Our approach to emotion emphasized three key ingredients. We do not yet have a mature science of emotion, or even a consensus view—in this respect we are more hesitant than Sander, Grandjean, and Scherer or Luiz Pessoa. Relatedly, a science of emotion needs to be highly interdisciplinary, including ecology, psychology, neuroscience, and philosophy. We recommend a functionalist view that brackets conscious experiences and that essentially treats emotions as latent variables inferred from a number of measures. But our version of functionalism (...) is not definitional or ontological. It is resolutely methodological, in good part because it is too early to attempt definitions. (shrink)

The expressivist advances a view about how we explain the meaning of a fragment of language, such as claims about what we morally ought to do. Critics evaluate expressivism on those terms. This is a serious mistake. We don’t just use that fragment of language in isolation. We make claims about what we morally, legally, rationally, and prudentially ought to do. To account for this linguistic phenomenon, the expressivist owes us an account not just of each fragment of language, but (...) of how they weave together into a broader tapestry. I argue that expressivists face a dilemma in doing so: either they fail to explain the univocality of terms like 'ought', or they fail to explain when normative statements are and aren't inconsistent. (shrink)

I argue that existing objectivist accounts of subjective reasons face systematic problems with cases involving probability and possibility. I then offer a diagnosis of why objectivists face these problems, and recommend that objectivists seek to provide indirect analyses of subjective reasons.

We argue that generic generalizations about racial groups are pernicious in what they communicate (both to members of that racial group and to members of other racial groups), and may be central to the construction of social categories like racial groups. We then consider how we should change and challenge uses of generic generalizations about racial groups.

In this paper, I outline a heuristic for thinking about the relation between explanation and understanding that can be used to capture various levels of “intimacy”, between them. I argue that the level of complexity in the structure of explanation is inversely proportional to the level of intimacy between explanation and understanding, i.e. the more complexity the less intimacy. I further argue that the level of complexity in the structure of explanation also affects the explanatory depth in a similar way (...) to intimacy between explanation and understanding, i.e. the less complexity the greater explanatory depth and vice versa.

What do normative terms like “obligation” mean in legal contexts? On one view, which H.L.A. Hart may have endorsed, “obligation” is ambiguous in moral and legal contexts. On another, which is dominant in jurisprudence, “obligation” has a distinctively moralized meaning in legal contexts. On a third view, which is often endorsed in philosophy of language, “obligation” has a generic meaning in moral and legal con- texts. After making the nature of and disagreements between these views precise, I show how linguistic (...) data militates against both rivals to the generic meaning view, and argue that this has significant implications for jurisprudence.

Many philosophers have assumed, without argument, that Wittgenstein influenced Austin. More often, however, this is vehemently denied, especially by those who knew Austin personally. We compile and assess the currently available evidence for Wittgenstein’s influence on Austin’s philosophy of language. Surprisingly, this has not been done before in any detail. On the basis of both textual and circumstantial evidence we show that Austin’s work demonstrates substantial engagement with Wittgenstein’s later philosophy. In particular, Austin’s 1940 paper, ‘The Meaning of a Word’, (...) should be construed as a direct response to and development of ideas he encountered in Wittgenstein’s Blue Book. Moreover, we argue that Austin’s mature speech-act theory in How to Do Things with Words was also significantly influenced by Wittgenstein. (shrink)

In some circles, faith is said to be one of three theological virtues, along with hope and agape. But not everyone thinks faith is a virtue, theological or otherwise. Indeed, depending on how we understand it, faith may well conflict with the virtues. In this chapter we will focus on the virtue of humility. Does faith conflict with humility, or are they in concord? In what follows, we will do five things. First, we will sketch a theory of the virtue (...) of humility. Second, we will summarize a common view of faith, arguably held by Thomas Aquinas among others, and we will argue that Thomistic faith is not an intellectual virtue and that it conflicts with humility in the domain of inquiry. Third, we will plump for an older view of faith, one that predates Aquinas by at least 1500 years, Markan faith. Fourth, we will argue that Markan faith is an intellectual virtue and it is in concord with humility in the domain of inquiry. Fifth, we will argue that Markan faith, unlike Thomistic faith, is a personal virtue and that it is in concord with humility in the domain of personal relationships, both human-human and human-divine.

Are there any deep or systematic connections between paternalism and people's rights? Perhaps the connection is definitional: part of what makes an action or policy paternalistic is that it violates a right. Or perhaps the connection is normative: paternalism is (always? often? only sometimes?) morally problematic because it violates people's rights (even if we don't define "paternalism" in terms of a rights violation). My main goal in this paper is to argue for the normative connection. Part of the task will (...) be to explain exactly what the normative connection is. That will involve answering the questions embedded in the claim as well as offering an account of the right(s) that is (are) connected to paternalism's normative status. (shrink)

Sarah McGrath argues that moral perception has an advantage over its rivals in its ability to explain ordinary moral knowledge. I disagree. After clarifying what the moral perceptualist is and is not committed to, I argue that rival views are both more numerous and more plausible than McGrath suggests: specifically, I argue that inferentialism can be defended against McGrath’s objections; if her arguments against inferentialism succeed, we should accept a different rival that she neglects, intuitionism; and, reductive epistemologists can appeal (...) to non-naturalist commitments to avoid McGrath’s counterexamples.

Mandatory minimum sentencing provisions have been a feature of the U.S. justice system since 1790. But they have expanded considerably under the war on drugs, and their use has expanded considerably under the Trump Administration; some states are also poised to expand drug-related mandatory minimums further in efforts to fight the current opioid epidemic. In this paper I outline and evaluate three prominent arguments for and against the use of mandatory minimums in the war on drugs—they appeal, respectively, to proportionality, (...) consistency, and efficiency. I ultimately defend the view that the use of mandatory minimums in the war on drugs is unjust. -/- . (shrink)

Although thought experiments were first discovered as a sui generis methodological tool by philosophers of science (most prominently by Ernst Mach), the tool can also be found – even more frequently – in contemporary philosophy. Thought experiments in philosophy and science have a lot in common. However, in this chapter we will concentrate on thought experiments in philosophy only. Their use has been the centre of attention of metaphilosophical discussion in the past decade, and this chapter will provide an overview (...) of the results this discussion has achieved and point out which issues are still open.

Since nothing about God is passive, and the perception of pain is inherently passive, then it seems that God does not know what it is like to experience pain. Nor would he be able to cause us to experience pain, for his experience would then be a sensation (which would require God to have senses, which he does not). My suggestion is that Berkeley avoids this situation by describing how God knows about pain “among other things” (i.e. as something whose (...) identity is intelligible in terms of the integrated network of things). This avoids having to assume that God has ideas (including pain) apart from his willing that there be perceivers who have specific ideas that are in harmony or not in harmony with one another.

Take “legal reality” to be the part of reality that actual legal thought and talk is dis- tinctively about, such as legal institutions, legal obligations, and legal norms. Our goal is to explore whether legal reality is disunified. To illustrate the issue, consider the possibility that an important metaphysical thesis such as positivism is true of one part of legal reality (legal institutions), but not another (legal norms). We offer two arguments that suggest that legal reality is disunified: one concerns (...) the heteroge- neity of different entities that are part of legal reality; the other concerns variation within legal thought and talk. We then show that taking the possibility of the disunity of legal reality seriously has important upshots for how we think about the positivist and antipositivist traditions, the debate between them, and their relation to other parts of legal theory, such as critical legal theory and legal realism.

One hundred and ninety participants (95 undergraduates and 95 employees) responded to a factorial survey in which a number of case-based organizational allocation tasks were described. Participants were asked to imagine themselves as employees in fictitious organizations and chose among three allocations of employee development schemes invested by the manager in different work groups. The allocations regarded how such investments should be allocated between two parties. Participants chose twice, once picking the fairest and once the best allocation. One between-subjects factor (...) varied whether the parties represented social (i.e., choosing among allocations between two different work groups) or temporal comparisons (i.e., choosing among allocations between the present and the following year). Another between-subjects factor varied whether participants’ in-group was represented by the parties or not. One allocation maximized the outcome to one party, another maximized the joint outcome received by both parties, and a third provided both parties with equal but lower outcomes. It was predicted that equality, although always deficient to both parties, would be the preferred allocation when parties represented social comparisons and when choices were based on fairness. When parties represented temporal comparisons, and when choices were based on preference, maximizing the joint outcome was hypothesized to be the preferred allocation. Results supported these hypotheses. Against what was predicted, whether the in-group was represented by the parties or not did not moderate the results, indicating that participants’ allocation preferences were not affected by self-interest. The main message is that people make sensible distinctions between what they prefer and what they regard as fair. The results were the same for participating students who imagined themselves as being employees and participants who were true employees, suggesting that no serious threats to external validity are committed when university students are used as participants.

The National Center for Biomedical Ontology is a consortium that comprises leading informaticians, biologists, clinicians, and ontologists, funded by the National Institutes of Health (NIH) Roadmap, to develop innovative technology and methods that allow scientists to record, manage, and disseminate biomedical information and knowledge in machine-processable form. The goals of the Center are (1) to help unify the divergent and isolated efforts in ontology development by promoting high quality open-source, standards-based tools to create, manage, and use ontologies, (2) to create (...) new software tools so that scientists can use ontologies to annotate and analyze biomedical data, (3) to provide a national resource for the ongoing evaluation, integration, and evolution of biomedical ontologies and associated tools and theories in the context of driving biomedical projects (DBPs), and (4) to disseminate the tools and resources of the Center and to identify, evaluate, and communicate best practices of ontology development to the biomedical community. Through the research activities within the Center, collaborations with the DBPs, and interactions with the biomedical community, our goal is to help scientists to work more effectively in the e-science paradigm, enhancing experiment design, experiment execution, data analysis, information synthesis, hypothesis generation and testing, and understand human disease.

Duas das principais controvérsias que têm ocupado aqueles que se dedicam à teoria aris- totélica do movimento animal são a controvérsia acerca da forma da cognição através da qual um animal irracional apreende um objeto como um objeto de desejo e a controvérsia acerca da função desempenhada pela cognição na explicação aristotélica dos movimentos voluntários de locomoção animal. Neste artigo, eu apresento uma teoria acerca das formas como o desejo e a cognição se articulam na teoria aristotélica segundo a qual (...) um animal irracional apreende um objeto como um objeto de desejo através da percepção incidental deste objeto e, ao contrário do que a maioria parece acreditar, esta percepção não tem sempre a mesma função na produção destes movimentos.

Our concern in this paper lies with a common argument from racial discrimination to realism about races: some people are discriminated against for being members of a particular race (i.e., racial discrimination exists), so some people must be members of that race (i.e., races exist). Error theorists have long responded that we can explain racial discrimination in terms of racial attitudes alone, so we need not explain it in terms of race itself. But to date there has been little detailed (...) discussion of whether it is better to explain racial discrimination in terms of race or in terms of racial attitudes alone. Our goal is to offer a novel and detailed argument in defense of explaining racial discrimination in terms of racial attitudes alone, by attending to the neglected phenomenon of misperception discrimination, which involves differential treatment due to misperceived race. We argue that the discriminatory action in misperception cases must be explained in the same way as cases where (according to the realist) the victim’s race is accurately perceived. Thus, the victim’s actual race cannot provide the best explanation. The main upshot of our argument is that explanatory arguments from racial discrimination to realism about race fail. (shrink)

This review article provides a new perspective on the ethics of green nudging. We advance a new model for assessing the ethical permissibility of green nudges (GNs). On this model, which provides normative guidance for policymakers, a GN is ethically permissible when the intervention is (1) efficacious, (2) cost-effective, and (3) the advantages of the GN (i.e. reducing the environmental harm) are not outweighed by countervailing costs/harms (i.e. for nudgees). While traditional ethical objections to nudges (paternalism, etc.) remain potential normative (...) costs associated with GNs, any such costs must be weighed against the injunction to reduce environmental harm to third parties.

Textual entailment is a relationship that obtains between fragments of text when one fragment in some sense implies the other fragment. The automation of textual entailment recognition supports a wide variety of text-based tasks, including information retrieval, information extraction, question answering, text summarization, and machine translation. Much ingenuity has been devoted to developing algorithms for identifying textual entailments, but relatively little to saying what textual entailment actually is. This article is a review of the logical and philosophical issues involved in (...) providing an adequate definition of textual entailment. We show that many natural definitions of textual entailment are refuted by counterexamples, including the most widely cited definition of Dagan et al. We then articulate and defend the following revised definition: T textually entails H = df typically, a human reading T would be justified in inferring the proposition expressed by H from the proposition expressed by T. We also show that textual entailment is context-sensitive, nontransitive, and nonmonotonic. (shrink)

Methodological naturalism arises as a topic in metaethics in two ways. One is the issue of whether we should be methodological naturalists when doing our moral theorising, and another is whether we should take a naturalistic approach to metaethics itself. Interestingly, these can come apart, and some naturalist programs in metaethics justify a non-scientific approach to our moral theorising. This paper discusses the range of approaches that fall under the general umbrella of methodological naturalism, and how naturalists view the role (...) of science in ethics and metaethics. It discusses how naturalism interacts with the use of intuitions, using conceptual analysis, and reflective equilibrium methods. Finally, it discusses some ways using scientific investigation can make distinctive contributions to ethics and metaethics. (shrink)

Pascal’s wager has received the attention of philosophers for centuries. Most of its criticisms arise from how the wager is often framed. We present Pascal’s wager three ways: in isolation from any further apologetic arguments, as leading toward a regimen intended to produce belief, and finally embedded in a larger apology that includes evidence for Christianity. We find that none of the common objections apply when the wager is presented as part of Pascal’s larger project. Pascal’s wager is a successful (...) argument in its proper place. However, the most interesting features of our first two presentations of the wager turn out to be either irrelevant or missing from our reading: infinite utility and the relativity of evidence. The successful wager is a boring wager. Still, this study shows us how the wager might profitably be incorporated into different apologetic contexts and why it often can’t. (shrink)

Analyzing the position of two philosophers whose views are recognizably divergent, W. O. Quine and M.

We offer two arguments against the halving repose to Sleeping Beauty. First, we show that halving violates the Epistemological Sure-Thing Principle, which we argue is a necessary constraint on any reasonable probability assignment. The constraint is that if hypothetically on C you assign to A the same probability you assign to A hypothetical on not-C, you must assign that probability to A simpliciter. Epistemically, it's a sure thing for you that A has this probability. Second, we show that halving violates (...) solid statistical reasoning (or draws absurdly irrelevant distinctions). (shrink)

We explore consequences of the view that to know a proposition your rational credence in the proposition must exceed a certain threshold. In other words, to know something you must have evidence that makes rational a high credence in it. We relate such a threshold view to Dorr et al.’s :277–287, 2014) argument against the principle they call fair coins: “If you know a coin won’t land tails, then you know it won’t be flipped.” They argue for rejecting fair coins (...) because it leads to a pervasive skepticism about knowledge of the future. We argue that the threshold view of evidence and knowledge gives independent grounds to reject fair coins. (shrink)

Grice, Lewis, and Skyrms proposed similar distinctions between kinds of meaning. The meaning of terms in human language, as Lewis and Skyrms had it, is ‘conventional’. Skyrms presented models showing how it is possible for conventional meaning to evolve in a population without reliance on pre-existing meaning. But one might think of conventionality as coming in degrees, based on whether the evolutionary process begins with ‘natural saliences’. We propose a theory of natural salience and several extensions of Skyrms’s models to (...) capture this notion. These models reveal that natural saliences can hinder, as well as help, the evolution of language. (shrink)

This paper examines the explanatory distinctness of wiring optimization models in neuroscience. Wiring optimization models aim to represent the organizational features of neural and brain systems as optimal (or near-optimal) solutions to wiring optimization problems. My claim is that that wiring optimization models provide design explanations. In particular, they support ideal interventions on the decision variables of the relevant design problem and assess the impact of such interventions on the viability of the target system.

In November 2022, OpenAI released ChatGPT, an incredibly sophisticated chatbot. Its capability is astonishing: as well as conversing with human interlocutors, it can answer questions about history, explain almost anything you might think to ask it, and write poetry. This level of achievement has provoked interest in questions about whether a chatbot might have something similar to human intelligence or even consciousness. Given that the function of a chatbot is to process linguistic input and produce linguistic output, we consider the (...) question whether a sophisticated chatbot might have inner speech. That is: Might it talk to itself, internally? We explored this via a conversation with ‘Playground’, a chatbot which is very similar to ChatGPT but more flexible in certain respects. We asked it questions which, plausibly, can only be answered if one first produces some inner speech. Here, we present our findings and discuss their philosophical significance. (shrink)

Team reasoning gives a simple, coherent, and rational explanation for human cooperative behavior. This paper investigates the robustness of team reasoning as an explanation for cooperative behavior, by assessing its long-run viability. We consider an evolutionary game theoretic model in which the population consists of team reasoners and ‘conventional’ individual reasoners. We find that changes in the ludic environment can affect evolutionary outcomes, and that in many circumstances, team reasoning may thrive, even under conditions that, at first glance, may seem (...) unfavorable. We also pursue several extensions that augment the basic account, and conclude that team reasoning is an evolutionarily viable mechanism with the potential to explain behavior in a range of human interactions.

It is envisioned that one day xenotransplantation will bring about a future where transplantable organs can be safely and efficiently grown in transgenic pigs to help meet the global organ shortage. While recent advances have brought this future closer, worries remain about whether it will be beneficial overall. The unique challenges and risks posed to humans that arise from transplanting across the species barrier, in addition to the costs borne by non-human animals, has led some to question the value of (...) xenotransplantation altogether. In response, we defend the value of xenotransplantation research, because it can satisfy stringent welfare conditions on the permissibility of animal research and use. Along the way, we respond to the alleged concerns, and conclude that they do not currently warrant a cessation or a curtailing of xenotransplantation research. (shrink)
