In the late summer of 1998, the authors, a cognitive scientist and a logician, started talking about the relevance of modern mathematical logic to the study of human reasoning, and we have been talking ever since. This book is an interim report of that conversation. It argues that results such as those on the Wason selection task, purportedly showing the irrelevance of formal logic to actual human reasoning, have been widely misinterpreted, mainly because the picture of logic current in psychology (...) and cognitive science is completely mistaken. We aim to give the reader a more accurate picture of mathematical logic and, in doing so, hope to show that logic, properly conceived, is still a very helpful tool in cognitive science. The main thrust of the book is therefore constructive. We give a number of examples in which logical theorizing helps in understanding and modeling observed behavior in reasoning tasks, deviations of that behavior in a psychiatric disorder (autism), and even the roots of that behavior in the evolution of the brain.

Although Kant (1998) envisaged a prominent role for logic in the argumentative structure of his Critique of Pure Reason, logicians and philosophers have generally judged Kantgeneralformaltranscendental logics is a logic in the strict formal sense, albeit with a semantics and a definition of validity that are vastly more complex than that of first-order logic. The main technical application of the formalism developed here is a formal proof that Kants logic is after all a distinguished subsystem of first-order logic, namely what (...) is known as geometric logic.

The paper traces some of the assumptions that have informed conservative naturalism in linguistic theory, critically examines their justification, and proposes a more liberal alternative.

There is a noticeable gap between results of cognitive neuroscientific research into basic mathematical abilities and philosophical and empirical investigations of mathematics as a distinct intellectual activity. The paper explores the relevance of a Wittgensteinian framework for dealing with this discrepancy.

We aim to show that Kant’s theory of time is consistent by providing axioms whose models validate all synthetic a priori principles for time proposed in the Critique of Pure Reason. In this paper we focus on the distinction between time as form of intuition and time as formal intuition, for which Kant’s own explanations are all too brief. We provide axioms that allow us to construct ‘time as formal intuition’ as a pair of continua, corresponding to time as ‘inner (...) sense’ and the external representation of time as a line Both continua are replete with infinitesimals, which we use to elucidate an enigmatic discussion of ‘rest’ in the Metaphysical foundations of natural science. Our main formal tools are Alexandroff topologies, inverse systems and the ring of dual numbers. (shrink)

Festschrift for Michiel van Lambalgen on the occasion of his retirement as professor of logic and cognitive science at the University of Amsterdam.

[OPEN ACCESS TARGET ARTICLE WITH COMMENTARIES AND RESPONSE] We develop a new model of how human agency-detection capacities and other socio-cognitive biases are involved in forming religious beliefs. Crucially, we distinguish general religious beliefs (such as *God exists*) from personal religious beliefs that directly refer to the agent holding the belief or to her peripersonal time and space (such as *God appeared to _me_ last night*). On our model, people acquire general religious beliefs mostly from their surrounding culture; however, people (...) use agency-intuitions and other low-level experiences to form personal religious beliefs. We call our model the Interactive Religious Experience Model (IREM). IREM inverts received versions of Hyperactive Agency-Detection Device Theory (HADD Theory): instead of saying that agency-intuitions are major causes of religious belief in general, IREM says that general belief in supernatural agents causes people to seek situations that trigger agency-intuitions and other experiences, since these enable one to form personal beliefs about those agents. In addition to developing this model, we (1) present empirical and conceptual difficulties with received versions of HADD Theory, (2) explain how IREM incorporates philosophical work on indexical belief, (3) relate IREM to existing anthropological and psychological research, and (4) propose future empirical research programs based on IREM.

The history of twentieth-century American psychology is often depicted as a history of the rise and fall of behaviorism. Although historians disagree about the theoretical and social factors that have contributed to the development of experimental psychology, there is widespread consensus about the growing and declining influence of behaviorism between approximately 1920 and 1970. Since such wide-scope claims about the development of American psychology are typically based on small and unrepresentative samples of historical data, however, the question rises to what (...) extent the received view is justified. This paper aims to answer this question in two ways. First, we use advanced scientometric tools to quantitatively analyze the metadata of 119.278 papers published in American journals between 1920 and 1970. We reconstruct the development and structure of American psychology using co-citation and co-occurrence networks and argue that the standard story needs reappraising. Second, we argue that the question whether behaviorism was the ‘dominant’ school of American psychology is historically misleading to begin with. Using the results of our bibliometric analyses, we argue that questions about the development of American psychology deserve more fine-grained answers. (shrink)

In western philosophy and beyond, a tension between pluralism and monism has sparked many developments and debates. Pluralism of norms, of forms of knowledge, of aesthetic and moral values, of interests etc. has often been pitted against monism. Monism usually implies a hierarchical order of such norms etc. After having traced the origin of this tension between pluralism and monism in ancient tragedy and philosophy, I’m asking in this article whether a rejection of monism and embrace of pluralism necessarily raises (...) the specter of inconsistency and contradiction. The threat of inconsistency need not be associated with pluralism as even with regard to logic an argument can be made for a ‘multiplicity of logics’, as van Lambalgen and Stenning argue in several places. They refer to the varieties in reasoning that can be observed in humans and which are partly due to there being ‘dual systems’ of reasoning: System 1 processes information fast, automatized, and emotional, while System 2 is rather slow, more deliberative, and more rational. In contrast to a widely held view, the authors argue that System 1 processing is not without logic, even though it is a different form of logic from System 2. In addition, the multiplicity of logics they discuss is related to the multiple semantics required for distinct domains of reasoning. This perspective raises the subsequent question how this pluralism can be available while maintaining consistency, how should the available options be configured or related to each other? In the remainer of this chapter I’m addressing several such options for configurating pluralism like: non-foundational pluralism and foundational pluralism, moderate or temporary pluralism, antagonistic pluralism, incompatible pluralism, incommensurable pluralism, ‘Anything goes’ pluralism, complementary pluralism, integrative pluralism, and interactive pluralism. The discussion and examples of these options show that irrespective of its domain, the encounter with different configurations of pluralism shows how some forms of pluralism are likely to be productive, whereas others are less so - which is an important lesson given the prominent pluralism of pluralisms in philosophy and beyond.

The paper by Fritz Hamm, Hans Kamp and Michiel van Lambalgen (in what follows abbreviated as ‘HKL’) is a very rich one. Not only does it contain a wealth of empirical and formal insights concerning the analysis of tense and aspect, planning and causality, and other phenomena, it also contains some penetrating remarks concerning the scope and method of semantic theory. It is the latter aspect of the paper that I want to make a few comments on in (...) what follows. (shrink)

In this paper we examine to what extent the lengths of the links in an animated articulated figure can be changed without the viewer being aware of the change. This is investigated in terms of a framework that emphasizes the role of attention in visual perception. We conducted a set of five experiments to establish bounds for the sen-sitivity to changes in length as a function of several parameters and the amount of attention available. We found that while length changes (...) of 3% can be perceived when the relevant links are given full attention, changes of over 20% can go unnoticed when attention is not focused in this way. These results provide general guidelines for algorithms that produce or process character motion data and also bring to light some of the potential gains that stand to be achieved with attention-based algorithms.

Hamm, Kamp, and van Lambalgen 2006 (hereafter HLK) propose to relate NL discourse to cognitive representations that also deal with world knowledge, planning, belief revision, etc. Surprisingly, to represent human cognition they use an event calculus "which has found applications in robotics". This comment argues that the robotics-based theory of HLK attributes too much to world knowledge and not enough to the ontology, centering, and other universals of NL semantics. It is also too Anglo-centric to generalize to languages of (...) other linguistic types. (shrink)

How do you know what you want? This deceptively simple question reveals a tension in how we relate to our desires. On the one hand, we sometimes think about desires as things that just happen to us, that we are passively subject to. In this case, knowing what you want is about trying to detect in which direction you are being pulled. On the other hand, it can be disturbing if people treat their desires as mere empirical phenomena they have (...) no special say over. When I express a desire, I seem to express a view of the world that can be justified, criticized, endorsed, or rejected. This seems to demand a different picture of how I know what I want. Richard Moran’s Authority and Estrangement offers a promising account of how to understand this tension. Regarding attitudes like belief and desire, we possess first-person authority; we are not just accurate observers, but we also bear a certain responsibility. This is because the existence of these attitudes depends on an evaluation that is up to us to maintain or reject. Although Moran develops this account convincingly for attitudes like belief, Authority and Estrangement fails to apply it convincingly to desires. The main obstacle is that our desires often diverge from our deliberative conclusion of what to pursue. The aim of this thesis is to apply Moran’s framework of first-person authority to desires in a way that better takes into account the specific complexities of desires. The main innovation of the modified Moranian account I propose, is to understand desires as commitments to prima facie, instead of overall, evaluations. This modified account can accommodate the recalcitrance and complexity of desires, while also allowing us to see our relation to our desires as one of first-person authority in Moran’s sense.

The Natural Problems, attributed to Aristotle, have gained much scholarly attention in the last decades, yet a systematic study of how the collection circulated in the Graeco-Roman Empire remains a blind spot in contemporary scholarship. Indeed, the Imperial Era is a seminal period for the history of the text, not just as a conduit between Aristotle and the Middle Ages – which in itself is essential for explaining the subsequent Arabic and Latin uptake of the Problems more clearly – but (...) also for the wealth of sources and testimonies it offers about the collection’s ancient readership and concrete use. The evidence shows that the collection sparked much debate among a range of ancient philosophers, doctors, sophists and scholars, both Greeks and Romans. This paper provides a selection of readings representative of the different socio-intellectual milieus in which the Problems circulated and the different agendas that it served. (shrink)

This article considers two different ways of formulating a desire-satisfaction theory of prudential value. The first version of the theory (the object view) assigns basic prudential value to the state of affairs that is the object of a person’s desire. The second version (the combo view) assigns basic prudential value to the compound state of affairs in which (a) a person desires some state of affairs and (b) this state of affairs obtains. My aims in this article are twofold. First, (...) I aim to highlight that these are not mere notational variants, but in fact have quite different implications, so that this distinction is not one that the theorist of prudential value should ignore. More positively, I argue that the object view is better able to capture what is distinctive and appealing about subjective theories of prudential value, on any plausible account of what the central subjectivist insight is.

Kant’s views on animals have received much attention in recent years. According to some, Kant attributed the capacity for objective perceptual awareness to non-human animals, even though he denied that they have concepts. This position is difficult to square with a conceptualist reading of Kant, according to which objective perceptual awareness requires concepts. Others take Kant’s views on animals to imply that the mental life of animals is a blooming, buzzing confusion. In this article I provide a historical reconstruction of (...) Kant’s views on animals, relating them to eighteenth-century debates on animal cognition. I reconstruct the views of Buffon and Reimarus and show that (i) both Buffon and Reimarus adopted a conceptualist position, according to which concepts structure the cognitive experience of adult humans, and (ii) that both described the mental life of animals as a blooming, buzzing confusion. Kant’s position, I argue, is virtually identical to that of Reimarus. Hence Kant’s views on animals support a conceptualist reading of Kant. The article further articulates the historical antecedents of the Kantian idea that concepts structure human cognitive experience and provides a novel account of how the ideas of similarity and difference were conceptualized in eighteenth-century debates on animal cognition.

In the human sciences, experimental research is used to establish causal relationships. However, the extrapolation of these results to the target population can be problematic. To facilitate extrapolation, we propose to use the statistical technique Latent Class Regression Analysis in combination with the analogical reasoning theory for extrapolation. This statistical technique can identify latent classes that differ in the effect of X on Y. In order to extrapolate by means of analogical reasoning, one can characterize the latent classes by a (...) combination of features, and then compare these features to features of the target.

A philosophical analysis of the future of art must explicate art’s nature, as well as discuss the historical nature of art practice. Only so can one explain those contemporary developments in art which have led many people to doubt whether art even has a future. Arguably, art practice as we know it started with the installing of the modern system of the fine arts. I explain the pragmatics of art so understood, and suggest that we can define art, internally. We (...) need not resort to a nominalist approach that claims that something is a work of art if some representative of the art world says it is. Instead of such empty proceduralism, I explain how all art’s focal objects, persons and activities are mutually adjusted and can only be understood in light of the whole. Within that whole of art practice, the contemporary samples of art’s alleged failure can be assessed. Now the modern system treats the arts as aesthetic, and prescribes that to judge a work one has to experience it for oneself. Why this should be so, I explain in terms of the perceivability of the artist in the work. Next, art develops as a whole rather than in a piecemeal manner. Particular contemporary works may alienate the audience from art practice, yet once they are recognisably in a procedure which has clear artistic potency they can be incorporated fruitfully in the modern system as explained. In all, the future of art is the future of the modern system, unless the system as a whole goes. We see this happen with the Taliban, but do not ourselves seem to be vulnerable to such onslaught. Yet, our culture may be in the process of eliminating the human mind from the objective reality, and if nothing stops us, art too will come to an end. Luckily, by then we will not be such as to lament that demise. (shrink)

Over the past years McDowell’s conceptualist theory has received mixed phenomenological reviews. Some phenomenologists have claimed that conceptualism involves an over-intellectualization of human experience. Others have drawn on Husserl’s work, arguing that Husserl’s theory of fulfillment challenges conceptualism and that his notion of “real content” is non-conceptual. Still others, by contrast, hold that Husserl’s later phenomenology is in fundamental agreement with McDowell’s theory of conceptually informed experience. So who is right? This paper purports to show that phenomenology does not have (...) to choose between any of these positions. Central to the outline I offer is that there are multiple approaches to non-conceptual content in play today. By separating them we can begin to oversee the diversity of phenomenological contributions to the debate about non-conceptual content. I conclude that current literature presents us with at least three sound phenomenological accounts of non-conceptual content, but also that these are generally not incompatible with conceptualism.

This is a review of Monika Michalowska's critical edition of question 3 from Richard Kilvington's questions commentary on the Sentences by Peter Lombard. It is published in open access under a CC BY 4.0 license.

This chapter examines the possibility of using AI technologies to improve human moral reasoning and decision-making, especially in the context of purchasing and consumer decisions. We characterize such AI technologies as artificial ethics assistants (AEAs). We focus on just one part of the AI-aided moral improvement question: the case of the individual who wants to improve their morality, where what constitutes an improvement is evaluated by the individual’s own values. We distinguish three broad areas in which an individual might think (...) their own moral reasoning and decision-making could be improved: one’s actions, character, or other evaluable attributes fall short of one’s values and moral beliefs; one sometimes misjudges or is uncertain about what the right thing to do is in particular situations, given one’s values; one is uncertain about some fundamental moral questions or recognizes a possibility that some of one’s core moral beliefs and values are mistaken. We sketch why one might think that AI tools could be used to support moral improvement in those areas, and describe two types of assistance: preparatory assistance, including advice and training supplied in advance of moral deliberation; and on-the-spot assistance, including on-the-spot advice and facilitation of moral functioning over the course of moral deliberation. Then, we turn to some of the ethical issues that AEAs might raise, looking in particular at three under-appreciated problems posed by the use of AI for moral self-improvement: namely, reliance on sensitive moral data; the inescapability of outside influences on AEAs; and AEA usage prompting the user to adopt beliefs and make decisions without adequate reasons.

Toon van Eijk: Spinoza in het licht van bewustzijnsontwikkeling De beroemde filosoof Spinoza is moeilijk te doorgronden. Emeritus hoogleraar Maarten van Buuren heeft in 2016 twee boeken over Spinoza gepubliceerd, waarin hij diens filosofie op nauwgezette en verhelderende manier analyseert. Volgens Van Buuren is de kern van Spinoza’s ethiek de bevrijding van bevoogding en het streven om in overeenstemming te leven met de wereld en met zichzelf. Een aantal sleutelbegrippen in Spinoza’s filosofie zijn de immanente, in de natuur-inwonende God, zelfbeschikking, (...) de rede, intuïtie, macht en zelftoe-eigening. In dit boek bespreekt Toon van Eijk deze sleutelbegrippen aan de hand van de analyse van Van Buuren en de filosofie van Maharishi Mahesh Yogi, de grondlegger van de Transcendente Meditatie (TM) techniek. Filosofische begrippen blijven echter tandeloos zonder mogelijkheden om deze ideeën te verwerkelijken. Een synthese van filosofisch redeneren en praktijken voor bewustzijnsontwikkeling is nodig. Hoewel Spinoza een ethiek zonder metafysica voorstond, is Van Eijk van mening dat daadwerkelijk wijs handelen moeilijk zonder enige metafysische bagage kan. (shrink)

Iconic photographs are visual arguments depicting an, often dramatic, particular situation showing victims of disasters. Spectators watching the photo of the particular situation, empathise with it, and project the feelings evoked onto the events that form the context for the scene in the picture. This mobilises them into political action. In the process, however, the depicted personal misery is perused to exemplify the larger events. The tragedy of iconic photographs is analysed not as the misery experienced by the depicted persons, (...) but as the breach of their right to shame which is required for the photo to acquire iconicity. Examples are addressed, as well as the contrast classes of the self-portrait and Byzantine icons. (shrink)

Objectives. The purpose of this study was to conduct the first randomized controlled trial (RCT) to evaluate the effectiveness of a second-generation mindfulness-based intervention (SG-MBI) for treating fibromyalgia syndrome (FMS). Compared to first generation mindfulness-based interventions, SG-MBIs are more acknowledging of the spiritual aspect of mindfulness. Design. A RCT employing intent-to-treat analysis. Methods. Adults with FMS received an 8-week SG-MBI known as meditation awareness training (MAT; n = 74) or an active control intervention known as cognitive behaviour theory for groups (...) (n = 74). Assessments were performed at pre-, post-, and 6-month follow-up phases. Results. Meditation awareness training participants demonstrated significant and sustained improvements over control group participants in FMS symptomatology, pain perception, sleep quality, psychological distress, non-attachment (to self, symptoms, and environment), and civic engagement. A mediation analysis found that (1) civic engagement partially mediated treatment effects for all outcome variables, (2) non-attachment partially mediated treatment effects for psychological distress and sleep quality, and (3) non-attachment almost fully mediated treatment effects for FMS symptomatology and pain perception. Average daily time spent in meditation was found to be a significant predictor of changes in all outcome variables. Conclusions. Meditation awareness training may be a suitable treatment for adults with FMS and appears to ameliorate FMS symptomatology and pain perception by reducing attachment to self. (shrink)

In this article , I first engage in some conceptual clarification of what the words "imagine," "imagining," and "imagination" can mean. Each has a constructive sense, an attitudinal sense, and an imagistic sense. Keeping the senses straight in the course of cognitive theorizing is important for both psychology and philosophy. I then discuss the roles that perceptual memories, beliefs, and genre truth attitudes play in constructive imagination, or the capacity to generate novel representations that go well beyond what's prompted by (...) one's immediate environment.

Imaginative representations are crucial to the generation of action--both pretense and plain action. But well-known theories of imagination on offer in the literature [1] fail to describe how perceptually-formatted imaginings (mental images) and motor imaginings function in the generation of action and [2] fail to recognize the important fact that spatially rich imagining can be integrated into one's perceptual manifold. In this paper, I present a theory of imagining that shows how spatially rich imagining functions in the generation of action. (...) I also describe the imaginative structures behind two under-explored forms of action: semi-pretense and pretense layering. In addition, I suggest that my theory of imagining meshes better than the competitors with current work in cognitive and affective neuroscience. (shrink)

In the final book of Logical Investigations from 1901, Husserl develops a theory of knowledge based on the intentional structure of consciousness. While there is some textual evidence that Husserl considered this to entail a critique of Kantian philosophy, he did not elaborate substantially on this. This paper reconstructs the covert critique of Kant’s theory of knowledge which LI contains. With respect to Kant, I discuss three core aspects of his theory of knowledge which, as Husserl’s reflections on Kant indicate, (...) Husserl was familiar with. These are the cooperation of two faculties for the justification of beliefs; the concept of a priori structures of knowledge Kant operated with; and the delivered transcendental proof of these structures. Regarding Logical Investigations, I first briefly outline the intentional structure of consciousness as presented in the fifth book and then turn to the theory of knowledge in the sixth book. I then clarify, partially on the basis of manuscripts and lecture notes, the covert critique of the three core aspects of Kant’s theory which the sixth book contains. (shrink)

Verrassend misschien voor filosofen buiten Frankrijk, maar in Parijs is wetenschap altijd een object van filosofische reflectie geweest – niet in de vorm van de analytische wetenschapsfilosofie zoals die buiten Frankrijk wordt onderwezen, maar onder de noemer van historische epistemologie, of soms ook wel kortweg épistémologie genoemd. Dit themanummer wil een inleiding zijn op deze traditie in haar denkers.

It is argued that, contrary to prevailing opinion, Bas van Fraassen nowhere uses the argument from underdetermination in his argument for constructive empiricism. It is explained that van Fraassen’s use of the notion of empirical equivalence in The Scientific Image has been widely misunderstood. A reconstruction of the main arguments for constructive empiricism is offered, showing how the passages that have been taken to be part of an appeal to the argument from underdetermination should actually be interpreted.

Decades of debate about scientific realism notwithstanding, we find ourselves bemused by what different philosophers appear to think it is, exactly. Does it require any sort of belief in relation to scientific theories and, if so, what sort? Is it rather typified by a certain understanding of the rationality of such beliefs? In the following dialogue we explore these questions in hopes of clarifying some convictions about what scientific realism is, and what it could or should be. En route, we (...) encounter some profoundly divergent conceptions of the nature of science and of philosophy. (shrink)

Jill de Villiers has argued that children's mastery of sentential complements plays a crucial role in enabling them to succeed at false-belief tasks. Josef Perner has disputed that and has argued that mastery of false-belief tasks requires an understanding of the multiplicity of perspectives. This paper attempts to resolve the debate by explicating attributions of desires and beliefs as extensions of the linguistic practices of making commands and assertions, respectively. In terms of these linguistic practices one can explain why desire-talk (...) will precede belief-talk and why even older children will have difficulty attributing incompatible desires. (shrink)

I argue that psychology and epistemology should posit distinct cognitive attitudes of religious credence and factual belief, which have different etiologies and different cognitive and behavioral effects. I support this claim by presenting a range of empirical evidence that religious cognitive attitudes tend to lack properties characteristic of factual belief, just as attitudes like hypothesis, fictional imagining, and assumption for the sake of argument generally lack such properties. Furthermore, religious credences have distinctive properties of their own. To summarize: factual beliefs (...) are practical setting independent, cognitively govern other attitudes, and are evidentially vulnerable. By way of contrast, religious credences have perceived normative orientation, are susceptible to free elaboration, and are vulnerable to special authority. This theory provides a framework for future research in the epistemology and psychology of religious credence. (shrink)

Imagination contributes to human agency in ways that haven't been well understood. I argue here that pathways from imagistic imagining to emotional engagement support three important agential capacities: 1. bodily preparedness for potential events in one's nearby environment; 2. evaluation of potential future action; and 3. empathy-based moral appraisal. Importantly, however, the kind of pathway in question (I-C-E-C: imagining-categorization-emotion-conceptualization) also enables engagement with fiction. So human enchantment with fiction is a consequence of imaginative pathways that make us the kind of (...) agents we are. Finally, I use this approach to address imaginative resistance and the paradox of fiction. [The version archived here is a penultimate draft.

I raise the question of what cognitive attitude self-deception brings about. That is: what is the product of self-deception? Robert Audi and Georges Rey have argued that self-deception does not bring about belief in the usual sense, but rather “avowal” or “avowed belief.” That means a tendency to affirm verbally (both privately and publicly) that lacks normal belief-like connections to non-verbal actions. I contest their view by discussing cases in which the product of self-deception is implicated in action in a (...) way that exemplifies the motivational role of belief. Furthermore, by applying independent criteria of what it is for a mental state to be a belief, I defend the more intuitive view that being self-deceived that p entails believing that p. Beliefs (i) are the default for action relative to other cognitive attitudes (such as imagining and hypothesis) and (ii) have cognitive governance over the other cognitive attitudes. I explicate these two relations and argue that they obtain for the product of self-deception. (shrink)

This work provides proof-search algorithms and automated counter-model extraction for a class of STIT logics. With this, we answer an open problem concerning syntactic decision procedures and cut-free calculi for STIT logics. A new class of cut-free complete labelled sequent calculi G3LdmL^m_n, for multi-agent STIT with at most n-many choices, is introduced. We refine the calculi G3LdmL^m_n through the use of propagation rules and demonstrate the admissibility of their structural rules, resulting in auxiliary calculi Ldm^m_nL. In the single-agent case, we (...) show that the refined calculi Ldm^m_nL derive theorems within a restricted class of (forestlike) sequents, allowing us to provide proof-search algorithms that decide single-agent STIT logics. We prove that the proof-search algorithms are correct and terminate. (shrink)

This paper claims that the standard characterization of the motivational role of belief should be supplemented. Beliefs do not only, jointly with desires, cause and rationalize actions that will satisfy the desires, if the beliefs are true; beliefs are also the practical ground of other cognitive attitudes, like imagining, which means beliefs determine whether and when one acts with those other attitudes as the cognitive inputs into choices and practical reasoning. In addition to arguing for this thesis, I take issue (...) with Velleman's argument that belief and imagining cannot be distinguished on the basis of motivational role. (shrink)

When someone says she believes that God exists, is she expressing the same kind of mental state as when she says she thinks that a lake bigger than Lake Michigan exists⎯i.e., does she refer to the same kind of cognitive attitude in both cases? Using evidence from linguistic corpora (Study 1) and behavioral experiments (Studies 2-4), the current work provides evidence that individuals typically use the word “believe” more in conjunction with statements about religious credences and “think” more in conjunction (...) with factual statements, pointing to two different understandings of claims made with these two terms. These patterns do not appear to reflect low-level differences based on the amount of consensus surrounding a particular claim, the extent to which the truth of a particular claim is known to the participant, or linguistic differences between religious and factual statements. We discuss implications of these findings for religious cognition (e.g., as supporting the theory that religious credences are qualitatively distinct from factual beliefs) as well as cognitive processes more broadly. Finally, we relate the present findings to prior theoretical work on differences between factual belief and religious credence. (shrink)

As artefacts, the worlds of digital games are designed and developed to fulfil certain expressive, functional, and experiential objectives. During play, players infer these purposes and aspirations from various aspects of their engagement with the gameworld. Influenced by their sociocultural backgrounds, sensitivities, gameplay preferences, and familiarity with game conventions, players construct a subjective interpretation of the intentions with which they believe the digital game in question was created. By analogy with the narratological notion of the implied author, we call the (...) figure to which players ascribe these intentions ‘the implied designer’. In this article, we introduce the notion of the implied designer and present an initial account of how appreciators ascribe meaning to interactive, fictional gameworlds and act within them based on what they perceive to be the designer’s intentions.

Three puzzles about self-deception make this mental phenomenon an intriguing explanatory target. The first relates to how to define it without paradox; the second is about how to make sense of self-deception in light of the interpretive view of the mental that has become widespread in philosophy; and the third concerns why it exists at all. In this paper I address the first and third puzzles. First, I define self-deception. Second, I criticize Robert Trivers' attempt to use adaptionist evolutionary psychology (...) to solve the third puzzle (existence). Third, I sketch a theory to replace that of Trivers. Self-deception is not an adaptation, but a spandrel in the sense that Gould and Lewontin give the term: a byproduct of other features of human (cognitive) architecture. Self-deception is so undeniable a fact of human life that if anyone tried to deny its existence, the proper response would be to accuse this person of it. (Allen Wood, 1988). (shrink)

I here defend historical entitlement theories of property rights against a popular charge. This is the objection that such theories fail because no convincing account of original appropriation exists. I argue that this argument assumes a certain reading of historical entitlement theory and I spell out an alternative reading against which it misfires. On this reading, the role of acts of original appropriation is not to justify but to individuate people’s holdings. I argue that we can identify which acts count (...) as original appropriation against the background of a general justification for a practice of property rights. On this view, what I will call ‘natural’ acts of original appropriation are acts by which a person begins to satisfy the general conditions for justified ownership. Finally, I offer an interpretation of John Locke's theory of appropriation along these lines and argue that it provides an attractive reading of his view. (shrink)

Some examples suggest that religious credences respond to evidence. Other examples suggest they are wildly unresponsive. So the examples taken together suggest there is a puzzle about whether descriptive religious attitudes respond to evidence or not. I argue for a solution to this puzzle according to which religious credences are characteristically not responsive to evidence; that is, they do not tend to be extinguished by contrary evidence. And when they appear to be responsive, it is because the agents with those (...) credences are playing what I call The Evidence Game, which in fundamental ways resembles the games of make-believe described by Walton's theory of make-believe.

We study whether it is possible to generalise Seidenfeld et al.’s representation result for coherent choice functions in terms of sets of probability/utility pairs when we let go of Archimedeanity. We show that the convexity property is necessary but not sufficient for a choice function to be an infimum of a class of lexicographic ones. For the special case of two-dimensional option spaces, we determine the necessary and sufficient conditions by weakening the Archimedean axiom.

Many cognitive scientists, having discovered that some computational-level characterization f of a cognitive capacity φ is intractable, invoke heuristics as algorithmic-level explanations of how cognizers compute f. We argue that such explanations are actually dysfunctional, and rebut five possible objections. We then propose computational-level theory revision as a principled and workable alternative.

Virtue ethics has now well and truly established itself as one of the main normative theories. It is now quite common, and indeed, expected, for virtue ethics to be included, alongside deontology and consequentialism, in any Moral Philosophy syllabus worth its salt. Students are typically introduced to virtue ethics only after studying the other two normative theories, and this often sets the scene for various sorts of misunderstandings, with students expecting virtue ethics to be based on the same set of (...) rules and assumptions as its rivals. Or at least, that is my experience. In this paper I want to focus on one such misunderstanding, which arises when trying to apply virtue ethics to our judgments of other people’s actions and behaviour. Although there are countless ways in which a theory can be misunderstood, it is worth guarding against this one in particular, given that it can lead someone who takes virtue ethics seriously to act in ways that are not virtuous, or even vicious. I begin by making a few remarks about the role of normative theory, and then go on to give four examples of how applying virtue ethics can lead to poor behaviour. In the final section I identify the mistake in question and conclude by noting how it can be avoided. (shrink)

In an earlier issue, I argue (2014) that psychology and epistemology should distinguish religious credence from factual belief. These are distinct cognitive attitudes. Levy (2017) rejects this distinction, arguing that both religious and factual “beliefs” are subject to “shifting” on the basis of fluency and “intuitiveness.” Levy’s theory, however, (1) is out of keeping with much research in cognitive science of religion and (2) misrepresents the notion of factual belief employed in my theory. So his claims don’t undermine my distinction. (...) I conclude by suggesting some approaches to empirically testing our views. (shrink)
