This paper is about a special version of PDL, proposed by Marcus Kracht, for reasoning about sibling ordered trees. It has four basic programs corresponding to the child, parent, left- and right-sibling relations in such trees. The original motivation for this language is rooted in the field of model-theoretic syntax. Motivated by recent developments in the area of semi-structured data, and, especially, in the field of query languages for XML (eXtensible Markup Language) documents, we revisit the language. This renewed interest (...) comes with a special focus on complexity and expressivity aspects of the language, aspects that have so far largely been ignored. We survey and derive complexity results, and spend most of the paper on the most important open question concerning the language: what is its expressive power? We approach this question from two angles: Which first-order properties can be expressed? And which second-order properties? While we are still some way from definitive answers to these questions, we discuss two first-order fragments of the PDL language for ordered trees, and show how the language can be used to express some typical (second-order) problems, like the boolean circuit and the frontier problem.

Foundationalist epistemologies, whether internalist or externalist, ground noetic structures in beliefs that are said to be foundational, or properly basic. It is essential to such epistemologies that they provide clear criteria for proper basicality. This proves, 1 argue, to be a thorny task, at least insofar as the goal is to provide a psychologically realistic reconstruction of our actual doxastic practices. I examine some of the difficulties, and suggest some implications, in particular for the externalist epistemology of Alvin Plantinga.

‘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.

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)

This paper explores some of the differences between the enactive approach in cognitive science and the extended mind thesis. We review the key enactive concepts of autonomy and sense-making . We then focus on the following issues: (1) the debate between internalism and externalism about cognitive processes; (2) the relation between cognition and emotion; (3) the status of the body; and (4) the difference between ‘incorporation’ and mere ‘extension’ in the body-mind-environment relation.

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)

We argue that the minimal biological requirements for consciousness include a living body, not just neuronal processes in the skull. Our argument proceeds by reconsidering the brain-in-a-vat thought experiment. Careful examination of this thought experiment indicates that the null hypothesis is that any adequately functional “vat” would be a surrogate body, that is, that the so-called vat would be no vat at all, but rather an embodied agent in the world. Thus, what the thought experiment actually shows is that the (...) brain and body are so deeply entangled, structurally and dynamically, that they are explanatorily inseparable. Such entanglement implies that we cannot understand consciousness by considering only the activity of neurons apart from the body, and hence we have good explanatory grounds for supposing that the minimal realizing system for consciousness includes the body and not just the brain. In this way, we put the brain-in-a-vat thought experiment to a new use, one that supports the “enactive” view that consciousness is a life-regulation process of the whole organism interacting with its environment.

This study is a new look at the question of how God can act upon the world, and whether the world can affect God, examining contemporary work on the metaphysics of causation and laws of nature, and current work in the theory of knowledge and mysticism. It has been traditional to address such questions by appealing to God’s omnipotence and omniscience, but this book claims that this is useless unless it can be shown how these two powers "work." Instead of (...) treating the familiar problems associated with omnipotence and omniscience, this book asks directly whether, and how, causal interactions between God and His world could occur: both between God and the physical world and between God and other minds, as well as between the world and God. Fales examines current thinking about the very nature of causation, laws of nature, and agency. (shrink)

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)

The phenomenon of perceptual persistence after the motion stops in shape-from-motion displays was used to study the influence of prior knowledge on the maintenance of a percept in awareness. In SFM displays an object composed of discontinuous line segments are embedded in a background of randomly oriented lines. The object only becomes perceptible when the line segments that compose the object and the lines that compose the background move in counterphase. Critically, once the movement of the line segments stops, the (...) percept of the object persists for a short period of time. In the present study, perceptual persistence for digits exceeded that reported for nonsense shapes composed of the same line segments. This result is taken as evidence that the processes involved in the persistence of SFM, and therefore sustained perception, are sensitive to top-down influences. (shrink)

The enactive approach offers a distinctive view of how mental life relates to bodily activity at three levels: bodily self-regulation, sensorimotor coupling, and intersubjective interaction. This paper concentrates on the second level of sensorimotor coupling. An account is given of how the subjectively lived body and the living body of the organism are related via dynamic sensorimotor activity, and it is shown how this account helps to bridge the explanatory gap between consciousness and the brain. Arguments by O'Regan, Noë, and (...) Myin that seek to account for the phenomenal character of perceptual consciousness in terms of ‘bodiliness’ and ‘grabbiness’ are considered. It is suggested that their account does not pay sufficient attention to two other key aspects of perceptual phenomenality: the autonomous nature of the experiencing self or agent, and the pre-reflective nature of bodily self-consciousness.

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.

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.

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.

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.

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)

Causal and predictive learning research often employs intuitive and familiar hypothetical scenarios to facilitate learning novel relationships. The allergist task, in which participants are asked to diagnose the allergies of a fictitious patient, is one example of this. In such studies, it is common practice to ask participants to ignore their existing knowledge of the scenario and make judgments based only on the relationships presented within the experiment. Causal judgments appear to be sensitive to instructions that modify assumptions about the (...) scenario. However, the extent to which prior knowledge continues to affect competition for associative learning, even after participants are instructed to disregard it, is unknown. To answer this, we created a cue competition design that capitalized on prevailing beliefs about the allergenic properties of various foods. High and low allergenic foods were paired with foods moderately associated with allergy to create two compounds; high + moderate and low + moderate. We expected high allergenic foods to produce greater competition for associative memory than low allergenic foods. High allergenic foods may affect learning either because they generate a strong memory of allergy or because they are more salient in the context of the task. We therefore also manipulated the consistency of the high allergenic cue-outcome relationship with prior beliefs about the nature of the allergies. A high allergenic food that is paired with an inconsistent allergenic outcome should generate more prediction error and thus more competition for learning, than one that is consistent with prior beliefs. Participants were instructed to either use or ignore their knowledge of food allergies to complete the task. We found that while participants were able to set aside their prior knowledge when making causal judgments about the foods in question, associative memory was weaker for the cues paired with highly allergenic foods than cues paired with low allergenic foods regardless of instructions. The consistency manipulation had little effect on this result, suggesting that the effects in associative memory are most likely driven by selective attention to highly allergenic cues. This has implications for theories of causal learning as well as the way causal learning tasks are designed. (shrink)

b>. Computational models of colour vision assume that the biological function of colour vision is to detect surface reflectance. Some philosophers invoke these models as a basis for 'externalism' about perceptual content (content is distal) and 'objectivism' about colour (colour is surface reflectance). In an earlier article (Thompson et al. 1992), I criticized the 'computational objectivist' position on the basis of comparative colour vision: There are fundmental differences among the colour vision of animals and these differences do not converge on (...) the detection of any single type of environmental property. David R. Hilbert (1992) has recently defended computational objectivism against my 'comparative argument;' his arguments are based on the externalist approach to perceptual content originally developed by Mohan Matthen (1988) and on the computationally inspired theory of the evolutionary basis for trichromacy developed by Roger N. Shepard (1990). The present article provides a reply to Hilbert with extensive criticism of both Matthen's and Shepard's theories. I argue that the biological function of colour vision is not to detect surface reflectance, but to provide a set of perceptual categories that can apply to objects in a stable way in a variety of conditions. Comparative research indicates that both the perceptual categories and the distal stimuli will differ according to the animal and its visual ecology; therefore externalism and objectivism must be rejected.

In Warrant and Proper Function, Alvin Plantinga claims that metaphysical naturalism, when joined to a naturalized epistemology, is self-undermining. Plantinga argues that naturalists are committed to a neoDarwinian account of our origins, and that the reliability of our cognitive faculties is improbable or unknown relative to that theory. If the theory is true, then we are in no position to know that, whereas theism, if true, underwrites cognitive reliability. I seek to turn the tables on Plantinga, showing that neoDarwinism provides (...) strong reasons for expecting general cognitive reliability, whereas the likelihood of that relative to theism is unknowable.

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)

Theodicies can be distinguished as “hard-nosed” or “good-hearted.” Typical features of each are given. I reject the former; they set the bar too low for God. Considerable discussion is devoted to Eleonore Stump's recent Wandering in Darkness, which sets the standard for good-hearted theodicies. I then develop the notion of a “perfect creature”, a possible being indistinguishable from God except lacking aseity, and argue that God should have created only perfect creatures. Since He did not, He is not. Theodicies, therefore, (...) are in trouble if there is a best possible world and it is a perfect creature world. (shrink)

Some philosophers deny that science can investigate the supernatural - specifically, the nature and actions of God. If a divine being is atemporal, then, indeed, this seems plausible - but only, I shall argue, because such a being could not causally interact with anything. Here I discuss in detail two major attempts, those of Stump and Kretzmann, and of Leftow, to make sense of theophysical causation on the supposition that God is eternal. These views are carefully worked out, and their (...) failures are instructive for any attempt to reconcileeternality with causal efficacy. I conclude by arguing that if knowledge of God is possible, in virtue of His effects upon the world, then it is science that must play the preeminent role in producing that knowledge. (shrink)

In this book, Christopher Evan Franklin develops and defends a novel version of event-causal libertarianism. This view is a combination of libertarianism--the view that humans sometimes act freely and that those actions are the causal upshots of nondeterministic processes--and agency reductionism--the view that the causal role of the agent in exercises of free will is exhausted by the causal role of mental states and events (e.g., desires and beliefs) involving the agent. Franklin boldly counteracts a dominant theory that has (...) similar aims, put forth by well-known philosopher Robert Kane. -/- Many philosophers contend that event-causal libertarians have no advantage over compatibilists when it comes to securing a distinctively valuable kind of freedom and responsibility. To Franklin, this position is mistaken. Assuming agency reductionism is true, event-causal libertarians need only adopt the most plausible compatibilist theory and add indeterminism at the proper juncture in the genesis of human action. The result is minimal event-causal libertarianism: a model of free will with the metaphysical simplicity of compatibilism and the intuitive power of libertarianism. And yet a worry remains: toward the end of the book, Franklin reconsiders his assumption of agency reductionism, arguing that this picture faces a hitherto unsolved problem. This problem, however, has nothing to do with indeterminism or determinism, or even libertarianism or compatibilism, but with how to understand the nature of the self and its role in the genesis of action. Crucially, if this problem proves unsolvable, then not only is event-causal libertarianism untenable, so also is event-causal compatibilism. (shrink)

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.

Essentialism--understood as the doctrine that there are natural kinds--can be sustained with respect to the most fundamental physical entities of the world, as I elsewhere argue.

A number of recent attempts to justify biological taxonomy are critically examined. I conclude (...) that theory partially justifies such taxonomies but supports only a weaker form of essentialism.

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.

In both Metaphysics Γ 4 and 5 Aristotle argues that Protagoras is committed to the view that all contradictions are true. Yet Aristotle’s arguments are not transparent, and later, in Γ 6, he provides Protagoras with a way to escape contradictions. In this paper I try to understand Aristotle’s arguments. After examining a number of possible solutions, I conclude that the best way of explaining them is to (a) recognize that Aristotle is discussing a number of Protagorean opponents, and (b) (...) import another of Protagoras’ views, namely the claim that there are always two logoi opposed to one another.
