This paper deals with different textual versions of the important Mandaic magic scroll called Zarazta ḏ-Hibil Ziua. There are around thirteen manuscripts in different Western collections that attest to the text of this talisman. These manuscripts reveal great diversity. The general textual scope and literary structure of each manuscript are investigated. This allows an initial grouping of the texts into several text-types. The textual groupings are evaluated in light of various sorts of meta-textual data: the headings of the manuscripts, editorial (...) comments, and colophons. As a result, a working hypothesis about the possible relationship among different texts-types and the possible literary evolution of the work is suggested. (shrink)

Educational policy and social sciences researchers have been studying dishonest behaviors among students for a long time. In this bibliometric study we examine the extant literature on academic dishonesty until 2017. We also analyze the specific case of the literature on plagiarism since it is arguably one of the most common academic dishonest behavior. We aim at identifying the intellectual structure of the field of academic dishonesty and plagiarism. Results show that Donald L. McCabe and Richard L. Marsh appear as (...) the most productive authors. Furthermore, Whitley, 235–274, 1998) “Factors associated with cheating among college students: A review”, and Pennycook, 201–230, 1996), entitled “Borrowing others’ words: Text, ownership, memory, and plagiarism” are the most cited publications on academic dishonesty and on plagiarism, respectively. Additionally, a strong connection between the McCabe and Treviño articles emerged from the co-citation analysis on academic dishonesty, and also a strong relationship between Pennycook, 201–230, 1996) and Pecorari, 317–345, 2003), suggesting that these articles are strongly connected. Results suggest that these are the most influential authors and articles of the field. (shrink)

Both philosophers and psychologists have argued for the existence of distinct kinds of explanations, including teleological explanations that cite functions or goals, and mechanistic explanations that cite causal mechanisms. Theories of causation, in contrast, have generally been unitary, with dominant theories focusing either on counterfactual dependence or on physical connections. This paper argues that both approaches to causation are psychologically real, with different modes of explanation promoting judgments more or less consistent with each approach. Two sets of experiments isolate the (...) contributions of counterfactual dependence and physical connections in causal ascriptions involving events with people, artifacts, or biological traits, and manipulate whether the events are construed teleologically or mechanistically. The findings suggest that when events are construed teleologically, causal ascriptions are sensitive to counterfactual dependence and relatively insensitive to the presence of physical connections, but when events are construed mechanistically, causal ascriptions are sensitive to both counterfactual dependence and physical connections. The conclusion introduces an account of causation, an "exportable dependence theory," that provides a way to understand the contributions of physical connections and teleology in terms of the functions of causal ascriptions.

Following the “Encountering Human Rights” conference in January 2007, Emily Grabham interviewed Tania Pouwhare, a women’s rights activist working at the Women’s Resource Centre in London. Their discussion engaged with the professionalisation of activism, funding constraints and New Labour policies and their impact on immigrant women. Against a background of financial insecurity and huge demand for their services, many women’s organisations in the United Kingdom struggle to use human rights law to advance women’s rights. Nevertheless, the rhetoric of human (...) rights remains powerful within women’s activism, and law remains relevant as a potential form of ‘direct action’ and “another way of making a really big fuss”.

Teleological explanations (TEs) account for the existence or properties of an entity in terms of a function: we have hearts because they pump blood, and telephones for communication. While many teleological explanations seem appropriate, others are clearly not warranted-for example, that rain exists for plants to grow. Five experiments explore the theoretical commitments that underlie teleological explanations. With the analysis of [Wright, L. (1976). Teleological Explanations. Berkeley, CA: University of California Press] from philosophy as a point of departure, we examine (...) in Experiment 1 whether teleological explanations are interpreted causally, and confirm that TEs are only accepted when the function invoked in the explanation played a causal role in bringing about what is being explained. However, we also find that playing a causal role is not sufficient for all participants to accept TEs. Experiment 2 shows that this is not because participants fail to appreciate the causal structure of the scenarios used as stimuli. In Experiments 3-5 we show that the additional requirement for TE acceptance is that the process by which the function played a causal role must be general in the sense of conforming to a predictable pattern. These findings motivate a proposal, Explanation for Export, which suggests that a psychological function of explanation is to highlight information likely to subserve future prediction and intervention. We relate our proposal to normative accounts of explanation from philosophy of science, as well as to claims from psychology and artificial intelligence. (shrink)

Recent expansions of federal and state law enforcement databanks to include DNA samples and profiles of innocent persons threaten individual privacy, impose unjustifiable costs on society, and may undermine our pursuit of justice. The move to permanently retain DNA from arrestees and proposals for a universal database should be vigorously opposed on matters of principle, legality, and practicality.

Scientific and ‘intuitive’ or ‘folk’ theories are typically characterized as serving three critical functions: prediction, explanation, and control. While prediction and control have clear instrumental value, the value of explanation is less transparent. This paper reviews an emerging body of research from the cognitive sciences suggesting that the process of seeking, generating, and evaluating explanations in fact contributes to future prediction and control, albeit indirectly by facilitating the discovery and confirmation of instrumentally valuable theories. Theoretical and empirical considerations also suggest (...) why explanations may nonetheless feel intrinsically valuable. The paper concludes by considering some implications of the psychology of explanation for a naturalized philosophy of explanation. (shrink)

The issue of how to incorporate the individual's first‐hand experience of illness into broader medical understanding is a major question in medical theory and practice. In a philosophical context, phenomenology, with its emphasis on the subject's perception of phenomena as the basis for knowledge and its questioning of naturalism, seems an obvious candidate for addressing these issues. This is a review of current phenomenological approaches to medicine, looking at what has motivated this philosophical approach, the main problems it faces and (...) suggesting how it might become a useful philosophical tool within medicine, with its own individual, but interrelated, contribution to make to current medical debates. After the general background, there is a brief summary of phenomenological ideas and their current usage in a medical context. Next is a critique of four key claims within current phenomenological medical works, concerning both the role phenomenology plays and the supposedly clear divide between phenomenology and other approaches. There are significant problems within these claims, largely because they overlook the complexity of the questions they consider. Finally, there is some more in‐depth examination of phenomenology itself and the true complexity of phenomenological debate concerning subjectivity. The aim is to show that it will be both more productive and truer to phenomenology itself, if we use phenomenology as a philosophical method for explicating and gaining deeper understanding of complex and fundamental problems, which are central to medicine, rather than as providing simple, but flawed solutions.

The ability to generalize from the known to the unknown is central to learning and inference. Two experiments explore the relationship between how a property is explained and how that property is generalized to novel species and artifacts. The experiments contrast the consequences of explaining a property mechanistically, by appeal to parts and processes, with the consequences of explaining the property functionally, by appeal to functions and goals. The findings suggest that properties that are explained functionally are more likely to (...) be generalized on the basis of shared functions, with a weaker relationship between mechanistic explanations and generalization on the basis of shared parts and processes. The influence of explanation type on generalization holds even though all participants are provided with the same mechanistic and functional information, and whether an explanation type is freely generated (Experiment 1), experimentally provided (Experiment 2), or experimentally induced (Experiment 2). The experiments also demonstrate that explanations and generalizations of a particular type (mechanistic or functional) can be experimentally induced by providing sample explanations of that type, with a comparable effect when the sample explanations come from the same domain or from a different domains. These results suggest that explanations serve as a guide to generalization, and contribute to a growing body of work supporting the value of distinguishing mechanistic and functional explanations.

In pedagogical contexts and in everyday life, we often come to believe something because it would best explain the data. What is it about the explanatory endeavor that makes it essential to everyday learning and to scientific progress? There are at least two plausible answers. On one view, there is something special about having true explanations. This view is highly intuitive: it’s clear why true explanations might improve one’s epistemic position. However, there is another possibility—it could be that the process (...) of seeking, generating, or evaluating explanations itself puts one in a better epistemic position, even when the outcome of the process is not a true explanation. In other words, it could be that accurate explanations are beneficial, or it could be that high-quality explaining is beneficial, where there is something about the activity of looking for an explanation that improves our epistemic standing. The main goal of this paper is to tease apart these two possibilities, both theoretically and empirically, which we align with “Inference to the Best Explanation” and “Explaining for the Best Inference”, respectively. We also provide some initial support for EBI and identify promising directions for future research. (shrink)

On November 2, 2004, California voters elected to radically expand their state criminal DNA database through the passage of Proposition 69. The approved ballot initiative authorized DNA collection and retention from all felons, any individuals with past felony convictions – including juveniles – and, beginning in 2009, all adults arrested for any felony offense. This dramatic database expansion threatens civil liberties and establishes a dangerous precedent for U.S. criminal databases.

On November 2, 2004, California voters approved Proposition 69, “The DNA Fingerprint, Unsolved Crime, and Innocence Protection Act” by a margin of approximately 60 to 40 percent. Given the limited amount of information provided to voters during the initiative process, it is unclear how many of the yea-sayers were apprised of the full implications of this measure. Indeed, by voting “yes” on Proposition 69, California has elected to house the most radical and costly state criminal DNA database in the country. (...) This dangerous expansion of California's database poses tremendous threats to civil liberties and social justice while offering little, if anything, by way of increasing the safety of its citizens.Prior to November 2, California law required the permanent retention of DNA samples from felons convicted of serious, violent crimes. The new law expands the database to include DNA samples from all felons and individuals with past felony convictions - including juveniles - and, beginning in five years, all adults arrested for any felony offense.

Explanation has been an important topic of study in philosophy of science, in epistemology, and in other areas of philosophy. In parallel, psychologists have been studying children's and adults’ explanations, including their role in inference and in learning. This entry reviews recent work that begins to bridge the philosophy and psychology of explanation, with sections introducing recent empirical work on explanation by philosophers, formal and functional accounts of explanation, inference to the best explanation, the role of explanation in discovery, and (...) the implications of empirical work on explanation for the “negative program” in experimental philosophy.

Mental simulation — such as imagining tilting a glass to figure out the angle at which water would spill — can be a way of coming to know the answer to an internally or externally posed query. Is this form of learning a species of inference or a form of observation? We argue that it is neither: learning through simulation is a genuinely distinct form of learning. On our account, simulation can provide knowledge of the answer to a query even (...) when the basis for that answer is opaque to the learner. Moreover, through repeated simulation, the learner can reduce this opacity, supporting self-training and the acquisition of more accurate models of the world. Simulation is thus an essential part of the story of how creatures like us become effective learners and knowers. (shrink)

Musicians generally believe that memory differs from one person to the next. As a result, memorizing strategies that could be useful to almost everyone are not widely taught. We describe how an 18-years old piano student (Grade 7, ABRSM), learned to memorize by recording her thoughts, a technique inspired by studies of how experienced soloists memorize. The student, who had previously ignored suggestions that she play from memory, decided to learn to memorize, selecting Schumann’s “Der Dichter Spricht” for this purpose. (...) Rather than explicitly teaching the student how to memorize, the teacher taught her to record her thoughts while playing by marking them on copies of the score, adapting an approach used previously in research with experienced performers. Over a 6½ week period, the student recorded her thoughts during practice (five times) and while performing from memory for the teacher (three times). The student also video-recorded 3 weeks of practice, three performances, and the reconstruction of the piece from memory after a 9½-weeks break. The thoughts that the student reported were prepared during practice, stable over time, and functioned as memory retrieval cues during reconstruction. This suggests that the student memorized in the same way as the more experienced musicians who have been studied previously and that teaching student musicians to record their thoughts may be an effective way to help them memorize. The speed and durability of her memorization surprised the student, inspiring her to perform in public and to use the same technique for new pieces. (shrink)

Traditional approaches to moral psychology assumed that moral judgments resulted from the application of explicit commitments, such as those embodied in consequentialist or deontological philosophies. In contrast, recent work suggests that moral judgments often result from unconscious or emotional processes, with explicit commitments generated post hoc. This paper explores the intermediate position that moral commitments mediate moral judgments, but not through their explicit and consistent application in the course of judgment. An experiment with 336 participants finds that individuals vary in (...) the extent to which their moral commitments are consequentialist or deontological, and that this variation is systematically but imperfectly related to the moral judgments elicited by trolley car problems. Consequentialist participants find action in trolley car scenarios more permissible than do deontologists, and only consequentialists moderate their judgments when scenarios that typically elicit different intuitions are presented side by side. The findings emphasize the need for a theory of moral reasoning that can accommodate both the associations and dissociations between moral commitments and moral judgments. (shrink)

Summary Background Self-binding directives instruct clinicians to overrule treatment refusal during future severe episodes of illness. These directives are promoted as having potential to increase autonomy for individuals with severe episodic mental illness. Although lived experience is central to their creation, service users’ views on self-binding directives have not been investigated substantially. This study aimed to explore whether reasons for endorsement, ambivalence, or rejection given by service users with bipolar disorder can address concerns regarding self-binding directives, decision-making capacity, and human (...) rights. Methods This study used qualitative data from an internet-based survey distributed to the mailing list of the UK charity Bipolar UK, which contained multiple closed and open questions on advance decision-making in bipolar disorder. Quantitative analysis of a closed question about self-binding directives had already demonstrated endorsement amongst a very high proportion of participants with bipolar disorder who completed the survey. We conducted thematic analysis of responses from those participants who answered a subsequent open question about reasons for their view. Research was co-produced within a multi-disciplinary team, with clinical, legal, and ethical expertise, and lived experience of bipolar disorder. Ideas and methodologies associated with all these areas of expertise were used in the analysis of these reasons and to gain insight into the thoughts of individuals with bipolar disorder about self-binding directives and associated issues. Findings Between Oct 23 and Dec 5, 2017, 932 individuals with a self-reported clinical diagnosis of bipolar disorder completed the internet survey, with 565 (154 men; 400 women; 11 transgender or other) providing free text answers to the open question. A large majority of respondents endorsed self-binding directives, nearly all describing a determinate shift to types of distorted thinking and decision-making when unwell as their key justification. Responses indicating ambivalence were dominated by logistical concerns about the drafting and implementation of self-binding directives, while those who rejected self-binding directives also cited logistical concerns, validity of their thinking when unwell, and potential contravention of human rights. Interpretation This study is, to our knowledge, the first large study of reasons why mental health service users might endorse or reject the use of self-binding directives. The findings provide empirical support for introducing self-binding directives into mental health advance decision-making practice and policy and may help to address enduring ethical concerns surrounding possible implementation of the directive while a person retains decision-making capacity. The opinions expressed here in responses given by multiple service users with bipolar disorder challenge a prominent view within international disability rights debates that involuntary treatment and recognition of impaired mental capacity constitute inherent human rights violations.

Food Services generate solid waste from the production process and distribution of meal. The raw material, after a rational flow, is transformed into meals for consumption generating solid waste of variable composition and quantity. Waste recovery actions in the recycling and selective collection in these services act as inhibitors of the inadequate disposal of these wastes in the environment, contributing to environmental sustainability. The objective of this study is to analyze the generation and viability of commercialization of recyclable solid waste (...) in Food Services of companies located in Cuiabá and Várzea Grande, Mato Grosso – Brazil. This is a cross-sectional exploratory study with a convenience sample. The analysis of the generation of residues was carried out using the weighing method and generation indices using descriptive statistics. In order to verify the economic potential of recyclable waste, the value of intermediate consumption was used and sales price data were obtained by means of the publication "Compromisso Empresarial para Reciclagem" CEMPRE. It was found that in six services the largest part of waste was made of plastic, and in two services it was paper and cardboard. The generation of aluminum was more significant in one service, being the residue that added more economic value in the commercialization. The generation of glass and tetra pack packaging were not significant, and the recycling of both is not of interest to the scavengers. The results indicate that the commercialization of recyclable solid waste is viable. (shrink)

Recent theoretical and empirical work suggests that explanation and categorization are intimately related. This paper explores the hypothesis that explanations can help structure conceptual representations, and thereby influence the relative importance of features in categorization decisions. In particular, features may be differentially important depending on the role they play in explaining other features or aspects of category membership. Two experiments manipulate whether a feature is explained mechanistically, by appeal to proximate causes, or functionally, by appeal to a function or goal. (...) Explanation type has a significant impact on the relative importance of features in subsequent categorization judgments, with functional explanations reversing previously documented effects of [”]causal status’. The findings suggest that a feature’s explanatory importance can impact categorization, and that explanatory relationships, in addition to causal relationships, are critical to understanding conceptual representation.

O presente artigo procura refletir como elementos das tecnologias da informação e comunicação na educação se localizam na epistemologia hermenêutica. Essa realidade acaba gerando um enorme desafio à educação no sentido de encontrar “razões” que justifiquem, não só metodologias, mas o seu sentido de ser no mundo conectado. Partindo da “compreensão” como modo de ser do indivíduo humano e, consequentemente, lócus apropriado para a reflexão e o fazer pedagógico pretende-se apresentar uma abordagem viável da TIC no processo educativo a partir (...) da epistemologia hermenêutica. O trabalho pretende apresentar a racionalidade hermenêutica como uma epistemologia totalmente viável para promover a compreensão teórica-conceitual da utilização das novas tecnologias da comunicação e informação no âmbito dos processos educativos contemporâneos, para tanto se ancora nas noções de compreensão e de linguagem, bem como nas noções de ciberespaço e hipertexto. Resultado de uma pesquisa bibliográfica nos autores já mencionados, bem como seus comentadores, na primeira parte procura apresentar a hermenêutica como alternativa epistemológica em face da crise da razão metafísica e científica, e na segunda parte, busca-se apresentar a relação entre as novas tecnologias da informação e comunicação e a racionalidade hermenêutica. Ao romper com a racionalidade técnico-científica da modernidade, compreende a hermenêutica como um paradigma epistemológico viável com vista à compreensão das tecnologias da informação e comunicação na educação, uma vez que, em função de tais tecnologias, a capacidade do homem contemporâneo de refletir e dizer a realidade requer bases teóricas e metodológicas que preservem as dimensões históricas e culturais nas quais o homem contemporâneo está inserido.

This paper proposes two interrelated arguments: first, it is argued that agro-commodity traders are uniquely placed at the crossroads of agricultural trade to benefit from agricultural commodity speculation; and second, that the networks constituting their operations are central to their hedging activities. The case of Cargill—the largest privately owned company in the United States and one of the largest agricultural traders in the world—is used to support this argument by unpacking its operations, structure, and hedging strategies. In order to connect (...) the operations of Cargill to its speculating strategies, this paper first traces how agriculture and finance have become increasingly intertwined leading to heightened agricultural commodity speculation. Second, Cargill will be positioned within this process by analyzing how it has financialized its own strategies and its Corporate Platform. Third, Black River Asset Management, Cargill’s private equity arm, will be analyzed to show how it uses the information moving through Cargill’s Platform to engage in hedging and/or speculation.

For people with Bipolar Affective Disorder, a self-binding (advance) directive (SBD), by which they commit themselves to treatment during future episodes of mania, even if unwilling, can seem the most rational way to deal with an imperfect predicament. Knowing that mania will almost certainly cause enormous damage to themselves, their preferred solution may well be to allow trusted others to enforce treatment and constraint, traumatic though this may be. No adequate provision exists for drafting a truly effective SBD and efforts (...) to establish such provision are hampered by very valid, but also paralysing ethical, clinical and legal concerns. Effectively, the autonomy and rights of people with bipolar are being 'protected' through being denied an opportunity to protect themselves. From a standpoint firmly rooted in the clinical context and experience of mania, this article argues that an SBD, based on a patient-centred evaluation of capacity to make treatment decisions (DMC-T) and grounded within the clinician-patient relationship, could represent a legitimate and ethically coherent form of self-determination. After setting out background information on fluctuating capacity, mania and advance directives, this article proposes a framework for constructing such an SBD, and considers common objections, possible solutions and suggestions for future research.

Information and computer technology has come to play an increasingly important role in medicine, to the extent that e-health has been described as a disruptive innovation or revolution in healthcare. The attention is very much focused on the technology itself, and advances that have been made in genetics and biology. This leads to the question: What is changing in medicine today concerning e-health? To what degree could these changes be characterized as a ‘revolution’? We will apply the work of Thomas (...) Kuhn, Larry Laudan, Michel Foucault and other philosophers—which offers an alternative understanding of progress and revolution in medicine to the classic discovery-oriented approach—to our analysis. Nowadays, the long-standing curative or reactive paradigm in medicine is facing a crisis due to an aging population, a significant increase in chronic diseases and the development of more expensive diagnostic tools and therapies. This promotes the evolution towards a new paradigm with an emphasis on preventive medicine. E-health constitutes an essential part of this new paradigm that seeks to solve the challenges presented by an aging population, skyrocketing costs and so forth. Our approach changes the focus from the technology itself toward the underlying paradigm shift in medicine. We will discuss the relevance of this approach by applying it to the surge in digital self-tracking through health apps and wearables: the recognition of the underlying paradigm shift leads to a more comprehensive understanding of self-tracking than a solely discovery-oriented or technology-focused view can provide.

ABSTRACTThe understanding of a wide array of practices related to fraud, bribery, corruption, and more widely, illicit practices have been capturing the attention of practitioners and management researchers worldwide. A substantial portion of the extant research has used university students to measure their actual or intended cheating behaviours and often studies have tested for variations across countries and cultures. We highlight some major concerns in this stream of inquiry and discuss both the definition and some inconclusive results in prior studies, (...) namely those deriving from differences in cheating behaviour across different cultural contexts. We suggest the need to examine intentionality, and further advance that intentionality may assume a reactive or a proactive essence. Depending on the social and formal contexts of different countries, both reactive and proactive intentions lead to distinct moral concerns, which we name in this work omorality or immorality.

Challenges to psychiatric stigma fall between a rock and a hard place. Decreasing one prejudice may inadvertently increase another. Emphasising similarities between mental illness and ‘ordinary’ experience to escape the fear-related prejudices associated with the imagined ‘otherness’ of persons with mental illness risks conclusions that mental illness indicates moral weakness and the loss of any benefits of a medical model. An emphasis on illness and difference from normal experience risks a response of fear of the alien. Thus, a ‘likeness-based’ and (...) ‘unlikeness-based’ conception of psychiatric stigma can lead to prejudices stemming from paradoxically opposing assumptions about mental illness. This may create a troubling impasse for anti-stigma campaigns. (shrink)

ObjectiveAre people with a characteristically large physiological sway rendered particularly unstable when standing on a moving surface? Is postural sway in standing individuals idiosyncratic? In this study, we examine postural sway in individuals standing normally, and when subtle continuous sinusoidal disturbances are applied to their support platform. We calculate consistency between conditions to verify if sway can be considered characteristic of each individual. We also correlate two different aspects of participants’ responses to disturbance; their sway velocity and their regulation of (...) body orientation.MethodsNineteen healthy adults (age 29.2 ± 3.2 years) stood freely on footplates coaxially aligned with their ankles and attached to a motorized platform. They had their eyes closed, and hips and knees locked with a light wooden board attached to their body. Participants either stood quietly on a fixed platform or on a slowly tilting platform (0.1 Hz sinusoid; 0.2 and 0.4 deg). Postural sway size was separated into two entities: (1) the spontaneous sway velocity component (natural random relatively rapid postural adjustments, RMS body angular velocity) and (2) the evoked tilt gain component (much slower 0.1 Hz synchronous tilt induced by the movement of the platform, measured as peak-to-peak (p-p) gain, ratio of body angle to applied footplate rotation).ResultsThere was no correlation between the velocity of an individual’s sway and their evoked tilt gain (r= 0.34,p= 0.15 andr= 0.30,p= 0.22). However, when considered separately, each of the two measurements showed fair to good absolute agreement within conditions. Spontaneous sway velocity consistently increased as participants were subjected to increasing disturbance. Participants who swayed more (or less) did so across all conditions [ICC(3,k)= 0.95]. Evoked tilt gain also showed consistency between conditions [ICC(3,k)= 0.79], but decreased from least to most disturbed conditions.ConclusionThe two measurements remain consistent between conditions. Consistency between conditions of two very distinct unrelated measurements reflects the idiosyncratic nature of postural sway. However, sway velocity and tilt gain are not related, which supports the idea that the short-term regulation of stability and the longer-term regulation of orientation are controlled by different processes.

Two studies examined the specificity of effects of explanation on learning by prompting 3- to 6-year-old children to explain a mechanical toy and comparing what they learned about the toy’s causal and non-causal properties to children who only observed the toy, both with and without accompanying verbalization. In Study 1, children were experimentally assigned to either explain or observe the mechanical toy. In Study 2, children were classified according to whether the content of their response to an undirected prompt involved (...) explanation. Dependent measures included whether children understood the toy’s functional-mechanical relationships, remembered perceptual features of the toy, effectively reconstructed the toy, and (for Study 2) generalized the function of the toy when constructing a new one. Results demonstrate that across age groups, explanation promotes causal learning and generalization, but does not improve (and in younger children, can even impair) memory for causally-irrelevant perceptual details.

The notion of belief appears frequently in cognitive science. Yet it has resisted definition of the sort that could clarify inquiry. How then might a cognitive science of belief proceed? Here we propose a form of pluralism about believing. According to this view, there are importantly different ways to "believe" an idea. These distinct psychological kinds occur within a multi-dimensional property space, with different property clusters within that space constituting distinct varieties of believing. We propose that discovering such property clusters (...) is empirically tractable, and that this approach can help sidestep merely verbal disputes about what constitutes “belief.”. (shrink)
