We report the results of three experiments designed to assess the role of suppositions in human reasoning. Theories of reasoning based on formal rules propose that the ability to make suppositions is central to deductive reasoning. Our first experiment compared two types of problem that could be solved by a suppositional strategy. Our results showed no difference in difficulty between problems requiring affirmative or negative suppositions and very low logical solution rates throughout. Further analysis of the error data showed a (...) pattern of responses, which suggested that participants reason from a superficial representation of the premises in these arguments and this drives their choice of conclusion. Our second experiment employed a different set of suppositional problems but with extremely similar proofs in terms of the rules applied and number of inferential steps required. As predicted by our interpretation of reasoning strategies employed in Experiment 1, logical performance was very much higher on these problems. Our third experiment showed that problems that could be solved by constructing an initial representation of the premises were easier than problems in which this representation was not sufficient. This effect was independent of the suppositional structure of the problems. We discuss the implications of this research for theories of reasoning based on mental models and inference rules.

A person who arrives at correct solutions via false premises is right and wrong simultaneously. Similarly, a person who generates “logical intuitions” through superficial heuristics can likewise be right and wrong at the same time. However, heuristics aren't guaranteed to deliver the logical solution, so the claim that system 1 can routinely produce the alleged system 2 response is unfounded.

Byrne's approach to the semifactual conditional captures the reasoning data. However, we argue that it does not account for the processes or principles by which people arrive at representations of even-if conditionals, upon which their reasoning is said to be based. Drawing upon recent work on the suppositional conditional we present such an account.

Two studies are reported which demonstrate that analytic responding on everyday reasoning problems can be increased and bias eliminated after training on the law of large numbers. Critical thinking problems involving belief-consistent, neutral, and inconsistent conclusions were presented. Belief bias was eliminated when a written justification of argument strength was elicited. However, belief-based responding was still evident when evaluations of the arguments were elicited using rating scales. This finding demonstrates a dissociation between analytic and belief-based responding as a function of (...) response format. In Experiment 2 an instructional condition designed to foster decontextualised reasoning was included but was ineffective in reducing the degree to which judgements were biased by beliefs. It was concluded that training which makes available the analytic strategies necessary to evaluate a problem has the potential to facilitate performance only if the requested response triggers conscious deliberation of the evidence.

The ability to reason independently from one's own goals or beliefs has long been recognised as a key characteristic of the development of formal operational thought. In this article we present the results of a study that examined the correlates of this ability in a group of 10-year-old children ( N = 61). Participants were presented with conditional and relational reasoning items, where the content was manipulated such that the conclusion to the arguments were either congruent, neutral, or incongruent with (...) beliefs, and either logically valid or logically invalid. Participants also received a measure of working memory capacity (the counting span task) and a measure of inhibitory control (the stop signal task). Indices of belief bias and logical reasoning on belief-based problems were predicted independently by both measures. In contrast logical reasoning on belief neutral problems was predicted by working memory alone. The findings suggest that executive functions play a key role in the development of children's ability to decontextualise their thinking. (shrink)

A controversial claim in recent dual process accounts of reasoning is that intuitive processes not only lead to bias but are also sensitive to the logical status of an argument. The intuitive logic hypothesis draws upon evidence that reasoners take longer and are less confident on belief–logic conflict problems, irrespective of whether they give the correct logical response. In this paper, we examine conflict detection under conditions in which participants are asked to either judge the logical validity or believability of (...) a presented conclusion, accompanied by measures of eye movement and pupil dilation. The findings show an effect of conflict, under both types of instruction, on accuracy, latency, gaze shifts, and pupil dilation. Importantly, these effects extend to conflict trials in which participants give a belief‐based response (incorrectly under logic instructions or correctly under belief instructions) demonstrating both behavioral and physiological evidence in support of the logical intuition hypothesis. (shrink)

Belief bias is the tendency for prior beliefs to influence people's deductive reasoning in two ways: through the application of a simple belief-heuristic and through the application of more effortful reasoning for unbelievable conclusions. Previous research indicates that cognitive ability is the primary determinant of the effect of beliefs on accuracy. In the current study, we show that the mere tendency to engage analytic reasoning is responsible for the effect of cognitive ability on motivated reasoning. The implications of this finding (...) for our understanding of the impact of individual differences on belief bias are discussed. (shrink)

The aim of the present research was to develop a difficulty model for logical reasoning problems involving complex ordered arrays used in the Graduate Record Examination. The approach used involved breaking down the problems into their basic cognitive elements such as the complexity of the rules used, the number of mental models required to represent the problem, and question type. Weightings for these different elements were derived from two experimental studies and from the reasoning literature. Based on these weights, difficulty (...) models were developed which were then tested against new data. The models had excellent predictive validity and showed the relative influence of rule based factors and factors relating to the number of underlying models. Different difficulty models were needed for different question types, suggesting that people used a variety of approaches and, at a wider level, that both mental models and mental rules may be used in reasoning.

Taking as its point of departure Leder's phenomenological discussion of the `absent' body, this article explores the nature of human corporeality as a site of transgression. The body, I argue, using a process metaphysic, is first and foremost excessive, driven by human desire rather than animal need: a sensual mode of existence organized around the pleasure/pain axis. To be excessive/transgressive, however, implies the crossing of boundaries or limits which vary according to history and culture, time and place. These issues are (...) illustrated through a range of thinkers from Bakhtin to Kristeva, Irigaray to Deleuze and Guattari. A full-scale endorsement of the poststructuralist position is, however, rejected in favour of an approach which steers a middle ground between these transgressive, more fluid arguments and a foundationalist ontology of the emotional body as an ongoing structure of lived experience. The article concludes with some reflections on the complex pattern of corporeal `appearances', some more pleasant than others, which characterize our bodily-being-in-the-world. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Save Us From Being Saved:Girard's Critical SoteriologySimon J. Taylor (bio)One of the most striking things about the work of René Girard is that it is an overarching critique of what it is to be saved. The paradox that Girard presents us with is that "salvation" is something from which we must be saved. This combination of salvation as something that must be avoided and something we desperately need appears (...) to have the characteristic of a "double bind," about which Girard has written so much.1 Are we then, even within Girard's own thesis, bound to the mimetic doubling of need and revulsion that can end only in the expulsion or death of a common victim? It is this question that I hope to explore in this article.Girard's Critique Of SalvationTo set out Girard's critique of salvation, it is first necessary to see that what he has come to call the victimage mechanism ("mécanisme victimaire") is, in fact, salvation. Girard's thesis states that desire is mimetic, based on the imitation of another's desire. "Desire is always an imitation of another desire, desire for the same object, and therefore, an inexhaustible source of conflicts and rivalries" (Girard 1978, 39). As the rivalry produced by this desire intensifies, it spreads and produces conflict and violence on a large scale. On an unlimited scale, Girard identifies this with the Hobbesian "war of all against all."2 And it is at this point that the victimage mechanism kicks in. It is at this point that the identification of a scapegoat and the expulsion or killing of the scapegoat produce unity and restore peace. It is this, in Girard's originary scene, that leads to the simultaneous origins of society and religion. In restoring unity to the group, and hence founding the community, the victim becomes sacred, a god. This in itself is an indicator of the salvific power that the scapegoat effects in the community. In order that the violence, once diverted, should not break out again, two things are necessary: ritual, specifically sacrifice, and myth. Ritual reenacts the founding murder upon which society is based, enabling the [End Page 21] participants to transfer their violence to another victim. Myth is the story told by the persecutors about the events that led to the creation of their community, that is, the founding murder. Thus, religion "dehumanizes violence; it protects man from his own violence by taking it out of his hands, transforming it into a transcendent and ever-present danger to be kept in check by the appropriate rites appropriately observed and by a modest and prudent demeanor.... religion protects man as long as its ultimate foundations are not revealed" (Girard 1978, 134–35). Salvation has happened, and a cult arises to disburse the effects of this salvation.It is important that we take this account of religion with full seriousness and do not regard it simply as the prologue to Girard's later promotion, even rehabilitation, of the Judaeo-Christian tradition. This is salvific: religion protects us from our own violence; it has mechanisms for bringing to an end outbreaks of that violence. Elsewhere Girard can speak of "the negative usefulness of religion as a social prop against anarchy and chaos" (Girard 1997, 162–63). This is salvation: violence is dealt with and human society can dwell in relative peace. Religion, on this account, is not "pie-in-the-sky," a transcendent deferral of gratification. It has real benefits to society today; it is attractive, elegant, and simple. What more could we want from religion?But Girard will not allow us to rest content with this account of religion. He is blunt when he declares that "most religions are based on a lie, which is the supposed guilt of the victim" (Girard 1993c, 32). Nietzsche wrote that "The sacrificial animal does not share the spectators' ideas about sacrifice, but one has never let it have its say,"3 and this is precisely the origin of Girard's critique of the salvation offered by religions based on scapegoating. Girard is attempting to let the sacrificial animal have its say. All too often, these... (shrink)

In this short think-piece we trace the newly emerging and rapidly expanding dimensions and dynamics of the “neuro-complex.” What this amounts to, we suggest, are a series of bio or neuro “convergences” of sorts regarding the brain and mental worlds, which in turn are traceable through what we term the bio-psych, pharma-psych, subjectivity-selves, wellness-enhancement, and the neuroculture-neurofutures relational nexuses. These issues are then illustrated through two brief case studies regarding brain scanning technologies and the problems and prospects of cognitive enhancement. (...) The paper concludes with some final reflections on these matters and a call for further research in this rich and challenging domain as the neuro-complex continues to expand in expected and unexpected, yet equally rich and fascinating, ways.

This article researches how a corporate code of ethics (CCE) implemented in local government X has influenced the behavior of its employees, middle managers, and managers. Metaphors from the existing and desired CCE elicited by these three groups provided information on how to improve the effectiveness of the CCE. This method proved to be very fruitful. It appeared that continuous systematic attention needed to be paid to the CCE after the CCE had been implemented, particularly by management. Initiatives from management (...) to start discussions about relevant questions of integrity appeared to be also necessary to make the topic a “normal” topic which employees were no longer afraid to discuss. In this way, the possibility could be created to develop collectively a “practical” frame of reference concerning relevant questions of integrity that would help employees to make decisions in difficult situations during their work in the future.

Memes, of the kind found often on the internet, are an increasingly significant medium of expressive activity. I develop a theory of their ontological nature and, in parallel, an analysis of the concept meme. On my view, memes are abstract artifacts made out of norms for production of instances. The norms say things like ‘use a certain image; add text of a certain kind; the text should be delivered in two chunks, one at the top of the image, one at (...) the bottom, etc.’ Instances of these memes are created when users follow these norms and publish the results. The concept meme is analyzed in terms of the notion of memographic practice, a historically situated form of activity within which memes are created and their instances produced and made public. (shrink)

I explore the interrelations between the ontological and aesthetic issues raised by ready-mades such as Duchamp’s Fountain. I outline a hylomorphic metaphysics which has two central features. First, hylomorphically complex objects have matter to which they are not identical. Secondly, when such objects are artefacts (including artworks), it is essential to them that they are the products of creative work on their matter. Against this background, I suggest that ready-mades are of aesthetic interest because they pose a dilemma. Is there (...) really an object, a sculpture, that is distinct from its matter, a urinal, which object is created merely by the artist’s choice of the urinal? Or are we dealing with a case in which an artist passes off something, a urinal, as if it were a sculpture, even though it is not one? (shrink)

I argue that it is rational for a person to believe the conjunction of her beliefs. This involves responding to the Lottery and Preface Paradoxes. In addition, I suggest that in normal circumstances, what it is to believe a conjunction just is to believe its conjuncts.

If science fiction is a genre, then attempts to think about the nature of science fiction will be affected by one’s understanding of what genres are. I shall examine two approaches to genre, one dominant but inadequate, the other better, but only occasionally making itself seen. I shall then discuss several important, interrelated issues, focusing particularly on science fiction : what it is for a work to belong to a genre, the semantics of genre names, the validity of attempts to (...) define genres, and the connections between genre and normativity. One important but neglected clue to the nature of genres lies in the kinds of disagreements they generate over the assignment of works to genres. I conclude by explaining why these disagreements tell us something about the nature of genres, and discussing in some detail two famous cases of disagreement about whether some work or works are science fiction.

Musical Platonists identify musical works with abstract sound structures but this implies that they are not created but only discovered. Jerrold Levinson adapts Platonism to allow for creation by identifying musical works with indicated sound structures. In this paper I explore the similarities between Levinson's view and Kit Fine's theory of qua objects. Fine offers the theory of qua objects as an account of constitution, as it obtains, for example, between a statue and the clay the statue is made out (...) of. I argue that Fine's theory does not adequately characterize the constitution relation and that the problems it faces extend to Levinson's account of musical works as indicated structures. I develop an alternative theory of constitution, based on the notion of being made out of. This approach to constitution enables me to offer an account of musical works as abstract objects that are constituted by sound structures. I argue that my account has several advantages over the Levinson/Fine approach. (shrink)

Constitution is the relation between something and what it is made of. Composition is the relation between something and its parts. I examine three different approaches to the relation between constitution and composition. One approach, associated with neo-Aristotelians like Mark Johnston and Kathrin Koslicki, identifies constitution with composition. A second, popular with those sympathetic to classical mereology such as Judith Thomson, defines constitution in terms of parthood. A third, advocated strongly by Lynne Baker, takes constitution to be somehow inconsistent with (...) relations of parthood. All of these approaches, I argue, face serious problems. I conclude, tentatively, that constitution and composition have nothing to do with each other. (shrink)

Inspired by Sara Ahmed’s notion of ‘queer use,’ I present and extend a neo-Aristotelian theory of artifacts to capture what I call ‘counter-use.’ The theory of artifacts is based on the idea that what they are, how they come to be, and what their functions are cannot be understood independently from each other. They come to exist when a maker imposes the concept of their substantial kind onto some matter by working on the matter to make an artifact of that (...) kind out of it. The extensions to this core theory that I describe are two. First, I show how using can be a kind of making and how disparate users may form what Benedict Anderson calls an imagined community. Second, I describe what I call an artifact’s historicity and suggest that, like its substantial kind, an artifact’s historicity is essential to it. On this basis, I characterize counter-use as use of an artifact by an imagined community that re-arranges an object’s historicity and hence brings into existence a numerically distinct object. Thus, politically motivated counter-use has genuine ontological implications. (shrink)

Memes are a prominent example of a kind of digital artifact. It is widely agreed that an integral component of meme-making is the way in which it makes use of other existing material. In this paper, I examine three different ways of understanding this making use of. First, it has been seen in economic terms, as a kind of poaching. Secondly, the cultural concept of (re)appropriation has been deployed. Finally, Lévi-Strauss’s notion of bricolage is often mentioned. I argue that despite (...) some interesting insights deriving from the first two approaches, it is the third that gives the most comprehensive and interesting take on meme-making. (shrink)

In 1956, W.B. Gallie introduced his idea of essentially contested concepts. In my paper, I offer a novel interpretation of his theory and argue that his theory, thus interpreted, is correct. The key to my interpretation lies in a condition Gallie places on essentially contested concepts that other interpreters downplay or dismiss: that the use of an essentially contested concept must be derived “from an original exemplar whose authority is acknowledged by all the contestant users of the concept.” This reveals (...) a similarity between Gallie’s views and the semantic externalist views of Hilary Putnam, and others, about natural kind terms like “water” and “tiger.” I argue that natural kind terms and terms for essentially contested concepts are two species of a single semantic genus. In the case of natural kind terms, a term refers to a natural kind, the exemplars are instances of that kind, and the relation between the exemplars and anything to which the term applies is co-membership of the kind. In the case of terms for essentially contested concepts, a term refers to an historical tradition, the exemplar is a stage or temporal part of that tradition, and the relation between the exemplar and anything to which the term refers is being the heir of. This allows me to understand the contests that alerted Gallie to the phenomenon of essentially contested concepts as contests over the ownership of historical traditions. (shrink)

I argue for the thesis (UL) that there are certain logical abilities that any rational creature must have. Opposition to UL comes from naturalized epistemologists who hold that it is a purely empirical question which logical abilities a rational creature has. I provide arguments that any creatures meeting certain conditions—plausible necessary conditions on rationality—must have certain specific logical concepts and be able to use them in certain specific ways. For example, I argue that any creature able to grasp theories must (...) have a concept of conjunction subject to the usual introduction and elimination rules. I also deal with disjunction, conditionality and negation. Finally, I put UL to work in showing how it could be used to define a notion of logical obviousness that would be well suited to certain contexts—e.g. radical translation and epistemic logic—in which a concept of obviousness is often invoked.

I argue that it is not ideally rational to believe that some of one's current beliefs are false, despite the impressive inductive evidence concerning others and our former selves. One's own current beliefs represent a commitment which would be undermined by taking some of them to be false. The nature of this commitment is examined in the light of Nagel's distinction between subjective and objective points of view. Finally, I suggest how we might acknowledge our fallibility consistently with this special (...) attitude to our own beliefs. (shrink)

Recent years have witnessed a growing interest in the measurement of health status. One of the most well-known health status instruments is the Sickness Impact Profile (SIP). This paper examines the nature, development and testing of the SIP (and its UK equivalent the FLP). The practical merits of these instruments are explained, and some cautionary remarks are offered about their limitations.

In this article I distinguish the notion of there being something it is like to be a certain kind of creature from that of there being something it is like to have a certain kind of experience. Work on consciousness has typically dealt with the latter while employing the language of the former. I propose several ways of analyzing what it is like to be a certain kind of creature and find problems with them all. The upshot is that even (...) if there is something it is like to have certain kinds of experience, it does not follow that there is anything it is like to be a certain kind of creature. Skepticism about the existence of something that it is like to be an F is recommended. (shrink)

I bring together social ontology and social epistemology by consideringsocial entities (``epistemic unities'') that are constituted by the holdingof epistemic relations between their members. In particular, I focus onthe relation of taking someone as an expert. Among the types of structuresexamined are ones with a single expert and one or more non-experts whomay or may not know of each other's situation; and ones with more thanone expert, including cases in which the relation between the experts ishierarchical and cases in which (...) it is symmetrical. These structures modela variety of social situations which can thus be given a unified treatment.Among the cases I discuss are persons, which I argue are multiple-expertunities of persons at times. Taking a person as a social unity like this offersa clear sense in which some groups can also be person-like. (shrink)

The Clinical Pastoral Education (CPE) model forthe provision of spiritual care represents theemergence of a secularized professionalpractice from a religiously-based theologicalpractice of chaplaincy. The transformation ofhospital chaplaincy into “spiritual careservices” is one means by which religioushealthcare ministry negotiates modernity, inthe particular forms of the secular realm ofbiomedicine and the pluralism of thecontemporary United States healthcaremarketplace. “Spiritual” is a labelstrategically deployed to extend the realm ofrelevance to any patient's “belief system,”regardless of his or her religious affiliation.“Theological” language is recast as a (...) tool forconceptualizing the “spiritual lens.” Suchmoves transform chaplaincy from a peripheralservice, applicable only to the few “religious”patients, into an integral element of patientcare for all. Such a secularized professionalpractice is necessary to demonstrate therelevance and utility of spiritual care for allhospital patients in an era of cost-containmentpriorities and managed care economics.

The thesis of the paper is that persons are similar to a kind of group: multiple-expert epistemic unities (MEUs). MEUs are groups in which there are multiple experts on whom other members of the group model their opinion. An example would be a group of children playing Telephone. Any child nearer the source is an 'expert' for any child further away. I argue that, with certain important qualifications, it is both rational and necessary for persons to treat their future selves (...) as experts (i.e. to satisfy Bas Van Fraassen's Principle of Reflection). This makes a person a kind of MEU. (The paper "Epistemic Unities" gives more details about different kinds of epistemic unities.). (shrink)

The paper contrasts two ways of understanding the apparently strange assertions of mad persons, finds them both problematic, and proposes an alternative. The first approach, exemplified by R.D. Laing, is to suppose that the beliefs of the mad person are ordinary but expressed in terms that make them appear irrational. The other approach, advocated by Silvano Arieti, is to take the words at face value but to attribute to the mad person a kind of deviant logic. I suggest, on the (...) basis of a Davidsonian approach, that the bizarre utterances of the mad simply cannot be understood adequately; they are, precisely, points at which accomodations of intepretation give out. This is what makes them symptoms of madness. (shrink)
