Robustness has long been recognized as an important parameter for evaluating game-theoretic results, but talk of ‘robustness’ generally remains vague. What we offer here is a graphic measure for a particular kind of robustness (‘matrix robustness’), using a three-dimensional display of the universe of 2 × 2 game theory. In such a measure specific games appear as specific volumes (Prisoner’s Dilemma, Stag Hunt, etc.), allowing a graphic image of the extent of particular game-theoretic effects in terms of those games. The (...) measure also allows for an easy comparison between different effects in terms of matrix robustness. Here we use the measure to compare the robustness of Tit for Tat’s well-known success in spatialized games (Axelrod, R. (1984). The evolution of cooperation . New York: Basic Books; Grim, P. et al. (1998). The philosophical computer: Exploratory essays in philosophical computer modeling . Cambridge, Mass: MIT Press) with the robustness of a recent game-theoretic model of the contact hypothesis regarding prejudice reduction (Grim et al. 2005. Public Affairs Quarterly, 19 , 95–125). (shrink)

We apply spatialized game theory and multi-agent computational modeling as philosophical tools: (1) for assessing the primary social psychological hypothesis regarding prejudice reduction, and (2) for pursuing a deeper understanding of the basic mechanisms of prejudice reduction.

Is simulation some new kind of science? We argue that instead simulation fits smoothly into existing scientific practice, but does so in several importantly different ways. Simulations in general, and computer simulations in particular, ought to be understood as techniques which, like many scientific techniques, can be employed in the service of various and diverse epistemic goals. We focus our attentions on the way in which simulations can function as (i) explanatory and (ii) predictive tools. We argue that a wide (...) variety of simulations, both computational and physical, are best conceived in terms of a set of common features: initial or input conditions, a mechanism or set of rules, and a set of results or output conditions. Studying simulations in these terms yields a new understanding of their character as well as a body of normative recommendations for the care and feeding of scientific simulations. (shrink)

First two paragraphs of the article, in lieu of an abstract: “What I am going to discuss in terms of response and responsivity is not just a special1kind of behavior with respect to the Other. Responding has rather to be understood as the genuine way in which we encounter the alien as alien. It will be shown that the experience of the Other, i.e., what Husserl calls Fremderfahrung, requires a new sort of responsive phenomenology. This kind of responsive phenomenology goes (...) beyond the traditional form of intentional phenomenology just as much as it leaves behind every sort of hermeneutics. Responding means more than intending or understanding. [note 1] In what follows I shall unfold some of the main features to be ascribed to responsive phenomenology, and in doing so I shall proceed in the following way. After having made some general remarks about the actual and the historical background of the alien, I shall first say something about the different meanings of the alien (Fremde) and about the place of the alien in our experience. The second part leads us to a turning-point where responsivity diverges from the basic underlying presuppositions to the phenomenology of intentional acts and to the hermeneutic interpretation of texts. In a third step I shall outline the key concepts of demand and response. I shall conclude by presenting some features of what I call logic of response.” Note 1: N.B.

Keeping track of what others believe is a central part of human social cognition. However, the social relevance of those beliefs can vary a great deal. Some belief attributions mostly tell us about what a person is likely to do next. Other belief attributions tell us more about a person's social identity. In this paper, I argue that we cope with this challenge by employing two distinct concepts of belief in our everyday social interactions. The epistemic concept of belief is (...) primarily used to keep track of what other people take to be true, and this informs how we predict and interpret their behaviors. The symbolic concept of belief, in contrast, is primarily used as a means of signaling one's social identity to other members of one's community. In turn, community members closely monitor each other's symbolic beliefs as a means of enforcing social norms. (shrink)

Social norms are commonly understood as rules that dictate which behaviors are appropriate, permissible, or obligatory in different situations for members of a given community. Many researchers have sought to explain the ubiquity of social norms in human life in terms of the psychological mechanisms underlying their acquisition, conformity, and enforcement. Existing theories of the psychology of social norms appeal to a variety of constructs, from prediction-error minimization, to reinforcement learning, to shared intentionality, to domain-specific adaptations for norm acquisition. In (...) this paper, we propose a novel methodological and conceptual framework for the cognitive science of social norms that we call normative pluralism. We begin with an analysis of the explanatory aims of the cognitive science of social norms. From this analysis, we derive a recommendation for a reformed conception of its explanandum: a minimally psychological construct that we call normative regularities. Our central empirical proposal is that the psychological underpinnings of social norms are most likely realized by a heterogeneous set of cognitive, motivational, and ecological mechanisms that vary between norms and between individuals, rather than by a single type of process or distinctive norm system. This pluralistic approach, we suggest, offers a methodologically sound point of departure for a fruitful and rigorous science of social norms. (shrink)

‘Virtue signaling’ is the practice of using moral talk in order to enhance one’s moral reputation. Many find this kind of behavior irritating. However, some philosophers have gone further, arguing that virtue signaling actively undermines the proper functioning of public moral discourse and impedes moral progress. Against this view, I argue that widespread virtue signaling is not a social ill, and that it can actually serve as an invaluable instrument for moral change, especially in cases where moral argument alone does (...) not suffice. Specifically, virtue signaling can change the broader public’s social expectations, which can in turn motivate the adoption of new, positive social norms. I also argue that the reputation-seeking motives underlying virtue signaling impose important constraints on virtue signalers’ behavior, which serve to keep the worst excesses of virtue signaling in check.

This is a preprint draft. Please cite published version (DOI: 10.1111/mila.12385). The aim of this paper is to provide a novel analysis of anorexia nervosa (AN) in the context of the sense of agency literature. I first show that two accounts of anorexia nervosa that we ought to take seriously— i.e., the first personal reports of those who have experienced it firsthand as well as the research that seeks to explain anorexic behavior from an empirical perspective— appear to be thoroughly (...) in tension with one another in their descriptions of anorexic actions. Rather than proceeding at this point by way of disregarding anorexic testimony as meaningless or insincere, I instead offer a positive account of the sense of agency in anorexia nervosa that renders these two depictions compatible. The resultant picture of anorexic behavior is one that accommodates current empirical findings while also providing valuable insight into how it is that anorexics can sincerely report feeling fully in control over their food restriction.

In the small but growing literature on the philosophy of country music, the question of how we ought to understand the genre’s notion of authenticity has emerged as one of the central questions. Many country music scholars argue that authenticity claims track attributions of cultural standing or artistic self-expression. However, careful attention to the history of the genre reveals that these claims are simply factually wrong. On the basis of this, we have grounds for dismissing these attributions. Here, I argue (...) for an alternative model of authenticity in which we take claims about the relative authenticity of country music to be evidence of ‘country’ being a dual character concept in the same way that it has been suggested of punk rock and hip-hop. Authentic country music is country music that embodies the core value commitments of the genre. These values form the basis of country artists’ and audiences’ practical identities. Part of country music’s aesthetic practice is that audiences reconnect with, reify, and revise this common practical identity through identification with artists and works that manifest these values. We should then think of authenticity discourse within country music as a kind of game within the genre’s practice of shaping and maintaining this practical identity. (shrink)

In this chapter, we explore a tension between the mindshaping hypothesis and commonsense Western ideas about moral agency and its relation to the social world. To illustrate this tension, we focus on the phenomenon of virtue signaling. We argue that moral intuitions about the perniciousness of virtue signaling reflect an individualistic conception of agency that we call the inside-out ideal. We argue that this ideal fits poorly with the deeply social, interactive, and regulative portrait of human nature revealed by the (...) mindshaping hypothesis. As an alternative to the inside-out ideal, we advocate for a more outside-in conception of agency. We argue that recent work on self control fits with such a conception, and show how it provides the virtue signaler with a path towards genuine moral growth that is scaffolded by mindshaping dynamics connected to reputational incentives and communal support, and should be accepted as perfectly morally legitimate.

In debates over the regulation of communication related to dual-use research, the risks that such communication creates must be weighed against against the value of scientific autonomy. The censorship of such communication seems justifiable in certain cases, given the potentially catastrophic applications of some dual-use research. This conclusion however, gives rise to another kind of danger: that regulators will use overly simplistic cost-benefit analysis to rationalize excessive regulation of scientific research. In response to this, we show how institutional design principles (...) and normative frameworks from free speech theory can be used to help extend the argument for regulating dangerous dual-use research beyond overly simplistic cost-benefit reasoning, but without reverting to an implausibly absolutist view of scientific autonomy.

How is human social intelligence engaged in the course of ordinary conversation? Standard models of conversation hold that language production and comprehension are guided by constant, rapid inferences about what other agents have in mind. However, the idea that mindreading is a pervasive feature of conversation is challenged by a large body of evidence suggesting that mental state attribution is slow and taxing, at least when it deals with propositional attitudes such as beliefs. Belief attributions involve contents that are decoupled (...) from our own primary representation of reality; handling these contents has come to be seen as the signature of full-blown human mindreading. However, mindreading in cooperative communication does not necessarily demand decoupling. We argue for a theoretical and empirical turn towards “factive” forms of mentalizing here. In factive mentalizing, we monitor what others do or do not know, without generating decoupled representations. We propose a model of the representational, cognitive, and interactive components of factive mentalizing, a model that aims to explain efficient real-time monitoring of epistemic states in conversation. After laying out this account, we articulate a more limited set of conversational functions for nonfactive forms of mentalizing, including contexts of meta-linguistic repair, deception, and argumentation. We conclude with suggestions for further research into the roles played by factive versus nonfactive forms of mentalizing in conversation. (shrink)

Both mindreading and stereotyping are forms of social cognition that play a pervasive role in our everyday lives, yet too little attention has been paid to the question of how these two processes are related. This paper offers a theory of the influence of stereotyping on mental-state attribution that draws on hierarchical predictive coding accounts of action prediction. It is argued that the key to understanding the relation between stereotyping and mindreading lies in the fact that stereotypes centrally involve character-trait (...) attributions, which play a systematic role in the action–prediction hierarchy. On this view, when we apply a stereotype to an individual, we rapidly attribute to her a cluster of generic character traits on the basis of her perceived social group membership. These traits are then used to make inferences about that individual’s likely beliefs and desires, which in turn inform inferences about her behavior. (shrink)

Character judgments play an important role in our everyday lives. However, decades of empirical research on trait attribution suggest that the cognitive processes that generate these judgments are prone to a number of biases and cognitive distortions. This gives rise to a skeptical worry about the epistemic foundations of everyday characterological beliefs that has deeply disturbing and alienating consequences. In this paper, I argue that this skeptical worry is misplaced: under the appropriate informational conditions, our everyday character-trait judgments are in (...) fact quite trustworthy. I then propose a mindreading-based model of the socio-cognitive processes underlying trait attribution that explains both why these judgments are initially unreliable, and how they eventually become more accurate.

how does one inquire into the truth of first principles? Where does one begin when deciding where to begin? Aristotle recognizes a series of difficulties when it comes to understanding the starting points of a scientific or philosophical system, and contemporary scholars have encountered their own difficulties in understanding his response. I will argue that Aristotle was aware of a Platonic solution that can help us uncover his own attitude toward the problem.Aristotle's central problem with first principles arises from the (...) fact that they cannot be demonstrated in the same way as other propositions. Since demonstrations proceed from prior and better-known principles, if the principles themselves were in need of... (shrink)

In this paper, I attempt to address a fundamental challenge for machine intelligence: to understand whether and how a machine’s internal states and external outputs can exhibit original non-derivative intentionality. This question has three aspects. First, what does it take for a machine to exhibit original de dicto intentionality? Second, what does it take to exhibit original de re intentionality? Third, what is required for the machine to defer to the external objective world by respecting the word-to-world direction of fit? (...) I attempt to answer the first challenge by providing a constitutive counts-as understanding of de dicto intentionality. This analysis involves repurposing Kant’s vision of a self-legislating agent as a specification of a machine that reprograms itself. I attempt to answer the second and third challenges by extending Kant’s synchronic model of de dicto intentionality with Brandom’s interpretation of Hegel’s diachronic model of de re intentionality, using Hegel’s notion of recollection to provide an understanding of what is involved in achieving deference to the external world.

A wide variety of scientific research projects include public participation in roles going beyond the classic use of subjects in human subjects research. “Participatory research” is an umbrella term for such projects. In this chapter, we begin by surveying the variety of participatory research approaches across fields. We examine what goals participatory research projects seek to achieve, both of social and scientific value. Next, we apply this theoretical framework to challenges that participatory research faces. We then survey three typologies of (...) participatory research projects, each of which can illuminate and guide decisions in project development. We end with a look at participatory research approaches in health contexts, applying the theoretical resources we introduced earlier in the chapter. (shrink)

This is a transcript of a conversation between P F Strawson and Gareth Evans in 1973, filmed for The Open University.

The Parmenides has been unduly overlooked in discussions of hypothesis in Plato. It contains a unique method for testing first principles, a method I call ‘exploring both sides’. The dialogue recommends exploring the consequences of both a hypothesis and its contradictory and thematizes this structure throughout. I challenge the view of Plato’s so-called ‘method of hypothesis’ as an isolated stage in Plato’s development; instead, the evidence of the Parmenides suggests a family of distinct hypothetical methods, each with its own peculiar (...) aim. Exploring both sides is unique both in its structure and in its aim of testing candidate principles. (shrink)

Traditionally, theories of mindreading have focused on the representation of beliefs and desires. However, decades of social psychology and social neuroscience have shown that, in addition to reasoning about beliefs and desires, human beings also use representations of character traits to predict and interpret behavior. While a few recent accounts have attempted to accommodate these findings, they have not succeeded in explaining the relation between trait attribution and belief-desire reasoning. On my account, character-trait attribution is part of a hierarchical system (...) for action prediction, and serves to inform hypotheses about agents’ beliefs and desires, which are in turn used to predict and interpret behavior.

This article gives two arguments for believing that our society is unknowingly guilty of serious, large-scale wrongdoing. First is an inductive argument: most other societies, in history and in the world today, have been unknowingly guilty of serious wrongdoing, so ours probably is too. Second is a disjunctive argument: there are a large number of distinct ways in which our practices could turn out to be horribly wrong, so even if no particular hypothesized moral mistake strikes us as very likely, (...) the disjunction of all such mistakes should receive significant credence. The article then discusses what our society should do in light of the likelihood that we are doing something seriously wrong: we should regard intellectual progress, of the sort that will allow us to find and correct our moral mistakes as soon as possible, as an urgent moral priority rather than as a mere luxury; and we should also consider it important to save resources and cultivate flexibility, so that when the time comes to change our policies we will be able to do so quickly and smoothly.

Groove, as a musical quality, is an important part of jazz and pop music appreciative practices. Groove talk is widespread among musicians and audiences, and considerable importance is placed on generating and appreciating grooves in music. However, musicians, musicologists, and audiences use groove attributions in a variety of ways that do not track one consistent underlying concept. I argue that that there are at least two distinct concepts of groove. On one account, groove is ‘the feel of the music’ and, (...) on the other, groove is the psychological feeling (induced by music) of wanting to move one’s body. Further, I argue that recent work in music psychology shows that these two concepts do not converge on a unified set of musical features. Finally, I also argue that these two concepts play different functional roles in the appreciative practices of jazz and popular music. This should cause us to further consider the mediating role genre plays for aesthetic concepts and provides us with reason for adopting a more communitarian approach to aesthetics which is attentive to the ways in which aesthetic discourse serves the practices of different audiences.

Nativists about theory of mind have typically explained why children below the age of four fail the false belief task by appealing to the demands that these tasks place on children’s developing executive abilities. However, this appeal to executive functioning cannot explain a wide range of evidence showing that social and linguistic factors also affect when children pass this task. In this paper, I present a revised nativist proposal about theory of mind development that is able to accommodate these findings, (...) which I call the pragmatic development account. According to this proposal, we can gain a better understanding of the shift in children’s performance on standard false-belief tasks around four years of age by considering how children’s experiences with the pragmatics of belief discourse affect the way they interpret the task.

Genre discourse is widespread in appreciative practice, whether that is about hip-hop music, romance novels, or film noir. It should be no surprise then, that philosophers of art have also been interested in genres. Whether they are giving accounts of genres as such or of particular genres, genre talk abounds in philosophy as much as it does the popular discourse. As a result, theories of genre proliferate as well. However, in their accounts, philosophers have so far focused on capturing all (...) of the categories of art that we think of as genres and have focused less on ensuring that only the categories we think are genres are captured by those theories. Each of these theories populates the world with far too many genres because they call a wide class of mere categories of art genres. I call this the problem of genre explosion. In this paper, I survey the existing accounts of genre and describe the kinds of considerations they employ in determining whether a work is a work of a given genre. After this, I demonstrate the ways in which the problem of genre explosion arises for all of these theories and discuss some solutions those theories could adopt that will ultimately not work. Finally, I argue that the problem of genre explosion is best solved by adopting a social view of genres, which can capture the difference between genres and mere categories of art. (shrink)

Clinical ethics consultants (CECs) are not moral authorities. Standardization of CECs’ professional role does not confer upon them moral authority. Certification of particular CECs does not confer upon them moral authority (nor does it reflect such authority). Or, so we will argue. This article offers a distinctly Orthodox Christian response to those who claim that CECs—or any other academically trained bioethicist—retain moral authority (i.e., an authority to know and recommend the right course of action). This article proceeds in three parts. (...) First, we discuss recent movements toward the certification of CECs in the United States, focusing primarily on proposals and programs put forth by the American Society for Humanities and Bioethics (ASBH). Second, we outline two secular reasons to be concerned about the relevant trends toward certification. For one thing, certification is currently being advanced via political dominance, rather than gaining authority by reliance on rigorous philosophical argument or reason. For another, the trends operate on the assumption that there exists a secular, content-full, canonical, morality. There is no such morality. Next, we argue that Orthodox Christians should resist the current trends toward certification of CECs. Specifically, we unpack ways in which the ASBH’s certification program (and those like it) conflict with Orthodox claims about moral authority and the moral life more generally. We conclude that Orthodox Christians should resist the current certification trends. (shrink)

This paper describes an attempt to repurpose Kant’s a priori psychology as the architectural blueprint for a machine learning system. First, it describes the conditions that must be satisfied for the agent to achieve unity of experience: the intuitions must be connected, via binary relations, so as to satisfy various unity conditions. Second, it shows how the categories are derived within this model: the categories are pure unary predicates that are derived from the pure binary relations. Third, I describe how (...) Kant’s cognitive architecture has been implemented in a computer system (the Apperception Engine) and show in detail what it is like for the system to construct a unified experience from a sequence of raw sensory input.

How should a machine intelligence perform unsupervised structure discovery over streams of sensory input? One approach to this problem is to cast it as an apperception task [1]. Here, the task is to construct an explicit interpretable theory that both explains the sensory sequence and also satisfies a set of unity conditions, designed to ensure that the constituents of the theory are connected in a relational structure. However, the original formulation of the apperception task had one fundamental limitation: it assumed (...) the raw sensory input had already been parsed using a set of discrete categories, so that all the system had to do was receive this already-digested symbolic input, and make sense of it. But what if we don't have access to pre-parsed input? What if our sensory sequence is raw unprocessed information? The central contribution of this paper is a neuro-symbolic framework for distilling interpretable theories out of streams of raw, unprocessed sensory experience. First, we extend the definition of the apperception task to include ambiguous (but still symbolic) input: sequences of sets of disjunctions. Next, we use a neural network to map raw sensory input to disjunctive input. Our binary neural network is encoded as a logic program, so the weights of the network and the rules of the theory can be solved jointly as a single SAT problem. This way, we are able to jointly learn how to perceive (mapping raw sensory information to concepts) and apperceive (combining concepts into declarative rules). (shrink)

To demarcate the limits of experimental knowledge, we probe the limits of what might be called an experiment. By appeal to examples of scientific practice from astrophysics and analogue gravity, we demonstrate that the reliability of knowledge regarding certain phenomena gained from an experiment is not circumscribed by the manipulability or accessibility of the target phenomena. Rather, the limits of experimental knowledge are set by the extent to which strategies for what we call ‘inductive triangulation’ are available: that is, the (...) validation of the mode of inductive reasoning involved in the source-target inference via appeal to one or more distinct and independent modes of inductive reasoning. When such strategies are able to partially mitigate reasonable doubt, we can take a theory regarding the phenomena to be well supported by experiment. When such strategies are able to fully mitigate reasonable doubt, we can take a theory regarding the phenomena to be established by experiment. There are good reasons to expect the next generation of analogue experiments to provide genuine knowledge of unmanipulable and inaccessible phenomena such that the relevant theories can be understood as well supported. This article is part of a discussion meeting issue ‘The next generation of analogue gravity experiments’. (shrink)

According to the two-systems account of mindreading, our mature perspective-taking abilities are subserved by two distinct mindreading systems: a fast but inflexible, “implicit” system, and a flexible but slow “explicit” one. However, the currently available evidence on adult perspective-taking does not support this account. Specifically, both Level-1 and Level-2 perspective-taking show a combination of efficiency and flexibility that is deeply inconsistent with the two-systems architecture. This inconsistency also turns out to have serious consequences for the two-systems framework as a whole, (...) both as an account of our mature mindreading abilities and of the development of those abilities. What emerges from this critique is a conception of context-sensitive, spontaneous mindreading that may provide insight into how mindreading functions in complex social environments. This in turn offers a bulwark against skepticism about the role of mindreading in everyday social cognition. (shrink)

Moral character judgments pervade our everyday social interactions. But are these judgments epistemically reliable? In this paper, I discuss a challenge to the reliability of ordinary virtue and vice attribution that emerges from Christian Miller’s Mixed Traits theory of moral character, which entails that the majority of our ordinary moral character judgments are false. In response to this challenge, I argue that a key prediction of this theory is not borne out by the available evidence; this evidence further suggests that (...) our moral character judgments do converge upon real psychological properties of individuals. I go on to argue that this is because the evidence for the Mixed Traits Theory does not capture the kind of compassionate behaviors that ordinary folk really care about. Ultimately, I suggest that our ordinary standards for virtue and vice have a restricted social scope, which reflects the parochial nature of our characterological moral psychology. (shrink)

At a crucial juncture in Plato’s Sophist, when the interlocutors have reached their deepest confusion about being and not-being, the Eleatic Visitor proclaims that there is yet hope. Insofar as they clarify one, he maintains, they will equally clarify the other. But what justifies the Visitor’s seemingly oracular prediction? A new interpretation explains how the Visitor’s hope is in fact warranted by the peculiar aporia they find themselves in. The passage describes a broader pattern of ‘exploring both sides’ that lends (...) insight into Plato’s aporetic method. (shrink)

In this paper, we highlight some problems for accounts of disability and enhancement that have not been sufficiently addressed in the literature. The reason, we contend, is that contemporary debates that seek to define, characterise or explain the normative valence of disability and enhancement do not pay sufficient attention to a wide range of cases, and the transition between one state and another. In section one, we provide seven cases that might count as disability or enhancement. We explain why each (...) case might count, and on what basis, and why it is been neglected. Each case is explained as a transition in what we call capacity space. We then argue that no definition of disability or enhancement addresses all of these cases, except for strict welfarist accounts of disability that do not rely on a depiction of any particular capacity. We argue further, however, that this is a serious deficiency of welfarist conceptions of disability. We then address objections to our account. (shrink)

In “Rethinking Norm Psychology,” Cecilia Heyes offers an insightful critique of nativist approaches to the psychology of norms and then proposes a plausible alternative model grounded in the theory of cognitive gadgets. We are broadly sympathetic to both the critique and to the cognitive-gadgets model, though our own pluralistic approach to the psychology of norms (Westra & Andrews, 2022) leads us to think that the range of psychological and ecological processes that contributes to our norm psychology is even more diverse (...) than what Heyes proposes. Here, though, we focus on Heyes’s conceptual critique of the nativist model and its explanatory target—namely, a system for representing and processing rules. Heyes’s criticism of this representational rule-based conception of the psychology of norms is quite sound. However, we will argue that Heyes’s alternative behavioral explanandum for the psychology of norms also fails to escape the gravitational pull of a rule-based approach. (shrink)

This paper attempts to answer a central question in unsupervised learning: what does it mean to “make sense” of a sensory sequence? In our formalization, making sense involves constructing a symbolic causal theory that both explains the sensory sequence and also satisfies a set of unity conditions. The unity conditions insist that the constituents of the causal theory – objects, properties, and laws – must be integrated into a coherent whole. On our account, making sense of sensory input is a (...) type of program synthesis, but it is unsupervised program synthesis. Our second contribution is a computer implementation, the Apperception Engine, that was designed to satisfy the above requirements. Our system is able to produce interpretable human-readable causal theories from very small amounts of data, because of the strong inductive bias provided by the unity conditions. A causal theory produced by our system is able to predict future sensor readings, as well as retrodict earlier readings, and impute (fill in the blanks of) missing sensory readings, in any combination. In fact, it is able to do all three tasks simultaneously. We tested the engine in a diverse variety of domains, including cellular automata, rhythms and simple nursery tunes, multi-modal binding problems, occlusion tasks, and sequence induction intelligence tests. In each domain, we test our engine's ability to predict future sensor values, retrodict earlier sensor values, and impute missing sensory data. The Apperception Engine performs well in all these domains, significantly out-performing neural net baselines. We note in particular that in the sequence induction intelligence tests, our system achieved human-level performance. This is notable because our system is not a bespoke system designed specifically to solve intelligence tests, but a general-purpose system that was designed to make sense of any sensory sequence.

I argue alongside some other scholars that there is a plausible reading of Spinoza’s philosophy of suicide which holds both of the following tenets: first, that suicides occur because of external conditions, and second, that there are at least some suicides which are rational. These two tenets require special attention because they seem to be the source of significant tension. For Spinoza, if one’s cognitions are to be the most adequate, they must be “disposed internally” (E2p29s/G II 114), or determined (...) more from one’s own mental nature than from “fortuitous encounters” with other things (E2p29s/G II 114). It may seem there is a conflict, then, in saying both that there are rational suicides in the Spinozist framework, and that suicides must always be a result of external conditions: it seems a suicide simply cannot be rational if it is the result of external conditions. But this tension, it will be shown, can be dissolved. Once this tension is dealt with, I offer some brief closing arguments. I explain how this reading of Spinoza’s philosophy of suicide can satisfy a call for new suicide research which avoids forms of over-individualism and epistemic injustice, and which encourages us to abolish oppressive conditions that lead to rational suicides.

The problem of the many threatens to show that, in general, there are far more ordinary objects than you might have thought. I present and motivate a solution to this problem using many-one identity. According to this solution, the many things that seem to have what it takes to be, say, a cat, are collectively identical to that single cat.

This paper formalizes part of the cognitive architecture that Kant develops in the Critique of Pure Reason. The central Kantian notion that we formalize is the rule. As we interpret Kant, a rule is not a declarative conditional stating what would be true if such and such conditions hold. Rather, a Kantian rule is a general procedure, represented by a conditional imperative or permissive, indicating which acts must or may be performed, given certain acts that are already being performed. These (...) acts are not propositions; they do not have truth-values. Our formalization is related to the input/ output logics, a family of logics designed to capture relations between elements that need not have truth-values. In this paper, we introduce KL3 as a formalization of Kant’s conception of rules as conditional imperatives and permissives. We explain how it differs from standard input/output logics, geometric logic, and first-order logic, as well as how it translates natural language sentences not well captured by first-order logic. Finally, we show how the various distinctions in Kant’s much-maligned Table of Judgements emerge as the most natural way of dividing up the various types and sub-types of rule in KL3. Our analysis sheds new light on the way in which normative notions play a fundamental role in the conception of logic at the heart of Kant’s theoretical philosophy. (shrink)

The current industrial revolution is said to be driven by the digitization that exploits connected information across all aspects of manufacturing. Standards have been recognized as an important enabler. Ontology-based information standard may provide benefits not offered by current information standards. Although there have been ontologies developed in the industrial manufacturing domain, they have been fragmented and inconsistent, and little has received a standard status. With successes in developing coherent ontologies in the biological, biomedical, and financial domains, an effort called (...) Industrial Ontologies Foundry (IOF) has been formed to pursue the same goal for the industrial manufacturing domain. However, developing a coherent ontology covering the entire industrial manufacturing domain has been known to be a mountainous challenge because of the multidisciplinary nature of manufacturing. To manage the scope and expectations, the IOF community kicked-off its effort with a proof-of-concept (POC) project. This paper describes the developments within the project. It also provides a brief update on the IOF organizational set up. (shrink)

D. Evans, Argumenty platońskie, transl. Zbigniew Nerczuk.

A recent controversy over the US National Science Advisory Board for Biosecurity's recommendation to censor two publications on genetically modified H5N1 avian influenza has generated concern over the threat to scientific freedom such censorship presents. In this paper, I argue that in the case of these studies, appeals to scientific freedom are not sufficient to motivate a rejection of censorship. I then use this conclusion to draw broader concerns about the ethics of dual-use research.

Social norms – rules governing which behaviours are deemed appropriate or inappropriate within a given community – are typically taken to be uniquely human. Recently, this position has been challenged by a number of philosophers, cognitive scientists, and ethologists, who have suggested that social norms may also be found in certain non-human animal communities. Such claims have elicited considerable scepticism from norm cognition researchers, who doubt that any non-human animals possess the psychological capacities necessary for normative cognition. However, there is (...) little agreement among these researchers about what these psychological prerequisites are. This makes empirical study of animal social norms difficult, since it is not clear what we are looking for and thus what should count as behavioural evidence for the presence (or absence) of social norms in animals. To break this impasse, we offer an approach that moves beyond contested psychological criteria for social norms. This approach is inspired by the animal culture research program, which has made a similar shift away from heavily psychological definitions of ‘culture’ and to become organized around a cluster of more empirically tractable concepts of culture. Here, we propose an analogous set of constructs built around the core notion of a normative regularity, which we define as a socially maintained pattern of behavioural conformity within a community. We suggest methods for studying potential normative regularities in wild and captive primates. We also discuss the broader scientific and philosophical implications of this research program with respect to questions of human uniqueness, animal welfare and conservation. (shrink)

This paper is a test case for the claim, made famous by Myles Burnyeat, that the ancient Greeks did not recognize subjective truth or knowledge. After a brief discussion of the issue in Sextus Empiricus, I then turn to Plato's discussion of Protagorean views in the Theaetetus. In at least two passages, it seems that Plato attributes to Protagoras the view that our subjective experiences constitute truth and knowledge, without reference to any outside world of objects. I argue that these (...) passages have been misunderstood and that on the correct reading, they do not say anything about subjective knowledge. I then try out what I take to be the correct reading of the passages. The paper concludes with a brief discussion of the importance of causes in Greek epistemology. (shrink)

Country music critics and scholars have noticed an apparent contradiction between the practical identity of country music and the image of the male country singer as the 'rhinestone cowboy'. In this case, the problem is one of how we can make sense of the rural, working-class, ruggedly masculinity persona common to the genre with its elaborately embroidered, brightly colored, and highly embellished male fashion. The intractability of this problem has led some to argue that the simplest solution is to just (...) deny the legitimacy of country music authenticity discourse altogether. That is, all the genre’s talk of the rural working class is inauthentic and should be discarded. Here, I argue that by accounting for country music authenticity in terms of the genre being a dual character concept, we can fully address the skeptic's worries. Beyond merely being compatible with the Nudie suit however, this notion of authenticity is also our best way of understanding the aesthetic value of the rhinestone cowboy image at all. The resulting picture, in which the suit primarily serves as an epistemic signifier of one’s standing in the country music community, allows for the Nudie suit to function as a class, and sometimes queer, commentary on mainstream culture.

Plato's Theaetetus discusses and ultimately rejects Protagoras's famous claim that "man is the measure of all things." The most famous of Plato's arguments is the Self-Refutation Argument. But he offers a number of other arguments as well, including one that I call the 'Future Argument.' This argument, which appears at Theaetetus 178a−179b, is quite different from the earlier Self-Refutation Argument. I argue that it is directed mainly at a part of the Protagorean view not addressed before , namely, that all (...) beliefs concerning one's own future sensible qualities are true. This part of the view is found to be inconsistent with Protagoras's own conception of wisdom as expertise and with his own pretenses at expertise in teaching. (shrink)

In recent years, there has been a heated debate about how to interpret findings that seem to show that humans rapidly and automatically calculate the visual perspectives of others. In the current study, we investigated the question of whether automatic interference effects found in the dot-perspective task (Samson, Apperly, Braithwaite, Andrews, & Bodley Scott, 2010) are the product of domain-specific perspective-taking processes or of domain-general “submentalizing” processes (Heyes, 2014). Previous attempts to address this question have done so by implementing inanimate (...) controls, such as arrows, as stimuli. The rationale for this is that submentalizing processes that respond to directionality should be engaged by such stimuli, whereas domain-specific perspective-taking mechanisms, if they exist, should not. These previous attempts have been limited, however, by the implied intentionality of the stimuli they have used (e.g. arrows), which may have invited participants to imbue them with perspectival agency. Drawing inspiration from “novel entity” paradigms from infant gaze-following research, we designed a version of the dot-perspective task that allowed us to precisely control whether a central stimulus was viewed as animate or inanimate. Across four experiments, we found no evidence that automatic “perspective-taking” effects in the dot-perspective task are modulated by beliefs about the animacy of the central stimulus. Our results also suggest that these effects may be due to the task-switching elements of the dot-perspective paradigm, rather than automatic directional orienting. Together, these results indicate that neither the perspective-taking nor the standard submentalizing interpretations of the dot-perspective task are fully correct. (shrink)

In this essay I argue that the central problem of Aristotle’s Metaphysics H (VIII) 6 is the unity of forms and that he solves this problem in just the way he solves the problem of the unity of composites – by hylomorphism. I also discuss the matter– form relationship in H 6, arguing that they have a correlative nature as the matter of the form and the form of the matter.

Genres inform our appreciative practices. What it takes for a work to be a good work of comedy is different than what it takes for a work to be a good work of horror, and a failure to recognize this will lead to a failure to appreciate comedies or works of horror particularly well. Likewise, it is not uncommon to hear people say that a film or novel is a good work, but not a good work of x (where x (...) is the genre of that work). A work can be good all things considered, but genre membership provides us with an additional set of evaluative criteria over and above those of the medium, which colors how we interpret and appreciate the work. Given this importance, it is not surprising that philosophers of art have been interested in providing an account of what, exactly, a genre is. Despite this interest, there is not widespread agreement about what it takes for something to be a genre, nor what kinds of considerations are relevant in determining whether a work is a member of that genre. Beyond this, we might also want to know to what degree we ought to consider genre in evaluating a work of art and why it should matter at all. Here, I explore the variety of recent theories that philosophers have taken up on the topic of genre and why we should ultimately think of genres as artistic practices rather than the alternatives.

Gorgias’ On Not-Being survives only in two divergent summaries. Diels–Kranz's classic edition prints the better-preserved version that appears in Sextus’ Aduersus Mathematicos. Yet, in recent years there has been rising interest in a second summary that survives as part of the anonymous De Melisso, Xenophane, Gorgia. The text of MXG is more difficult; it contains substantial lacunae that often make it much harder to make grammatical let alone philosophical sense of. As Alexander Mourelatos reports, one manuscript has a scribal note (...) that reads: "The original contains many errors; no one should blame me; I just copy what I see.". The treatise's state of preservation has aptly prompted Michael Gagarin to liken it to a black hole: "something we cannot see directly but know must exist because of certain effects it has on other objects.".

Plato’s Parmenides and Lysis have a surprising amount in common from a methodological standpoint. Both systematically employ a method that I call ‘exploring both sides’, a philosophical method for encouraging further inquiry and comprehensively understanding the truth. Both have also been held in suspicion by interpreters for containing what looks uncomfortably similar to sophistic methodology. I argue that the methodological connections across these and other dialogues relieve those suspicions and push back against a standard developmentalist story about Plato’s method. This (...) allows for a better understanding of why exploring both sides is explicitly recommended in the Parmenides and its role within Plato’s broader methodological repertoire. (shrink)
