Van der Henst argues that the theory of mental models lacks a pragmatic component. He fills the gap with the notion that reasoners draw the most relevant conclusions. We agree, but argue that theories need an element of “nondeterminism.” It is often impossible to predict either what will be most relevant or which particular conclusion an individual will draw.

This article presents a fundamental advance in the theory of mental models as an explanation of reasoning about facts, possibilities, and probabilities. It postulates that the meanings of compound assertions, such as conditionals (if) and disjunctions (or), unlike those in logic, refer to conjunctions of epistemic possibilities that hold in default of information to the contrary. Various factors such as general knowledge can modulate these interpretations. New information can always override sentential inferences; that is, reasoning in daily life is defeasible (...) (or nonmonotonic). The theory is a dual process one: It distinguishes between intuitive inferences (based on system 1) and deliberative inferences (based on system 2). The article describes a computer implementation of the theory, including its two systems of reasoning, and it shows how the program simulates crucial predictions that evidence corroborates. It concludes with a discussion of how the theory contrasts with those based on logic or on probabilities. (shrink)

How do people make deductions? The orthodox view in psychology is that they use formal rules of inference like those of a “natural deduction” system.Deductionargues that their logical competence depends, not on formal rules, but on mental models. They construct models of the situation described by the premises, using their linguistic knowledge and their general knowledge. They try to formulate a conclusion based on these models that maintains semantic information, that expresses it parsimoniously, and that makes explicit something not directly (...) stated by any premise. They then test the validity of the conclusion by searching for alternative models that might refute the conclusion. The theory also resolves long-standing puzzles about reasoning, including how nonmonotonic reasoning occurs in daily life. The book reports experiments on all the main domains of deduction, including inferences based on prepositional connectives such as “if” and “or,” inferences based on relations such as “in the same place as,” inferences based on quantifiers such as “none,” “any,” and “only,” and metalogical inferences based on assertions about the true and the false. Where the two theories make opposite predictions, the results confirm the model theory and run counter to the formal rule theories. Without exception, all of the experiments corroborate the two main predictions of the model theory: inferences requiring only one model are easier than those requiring multiple models, and erroneous conclusions are usually the result of constructing only one of the possible models of the premises.

We resolve the two problems that Hardman raises. The first problem arises from a misunderstanding: the crucial distinction is between one-model and multiple-model problems. The second problem illuminates a deeper principle: conclusions depend on the procedures for interpreting models. We describe an algorithm that obviates the problem and empirical work that reveals a new view of syllogistic reasoning.

Many claim that belief in God is like belief in Santa Claus have it out belief in God, or belief in Santa – is rational, and a direct parallel between the reasoning of the two sides is demonstrated. Many important arguments regarding theistic belief are discussed in some form. The article is intended for use in an introduction to philosophy, or an introductory philosophy of religion course, as a humorous way to foster discussion and expose students to criticisms of theistic (...) arguments, and to consider the possibility that theistic belief is no better than belief in the existence of Santa Claus.

The theory of mental models and its computer implementations have led to crucial experiments showing that no standard logic—the sentential calculus and all logics that include it—can underlie human reasoning. The theory replaces the logical concept of validity (the conclusion is true in all cases in which the premises are true) with necessity (conclusions describe no more than possibilities to which the premises refer). Many inferences are both necessary and valid. But experiments show that individuals make necessary inferences that are (...) invalid, e.g., Few people ate steak or sole; therefore, few people ate steak. Other crucial experiments show that individuals reject inferences that are not necessary but valid, e.g., He had the anesthetic or felt pain, but not both; therefore, he had the anesthetic or felt pain, or both. Nothing in logic can justify the rejection of a valid inference: a denial of its conclusion is inconsistent with its premises, and inconsistencies yield valid inferences of any conclusions whatsoever including the one denied. So inconsistencies are catastrophic in logic. In contrast, the model theory treats all inferences as defeasible (nonmonotonic), and inconsistencies have the null model, which yields only the null model in conjunction with any other premises. So inconsistences are local. Which allows truth values in natural languages to be much richer than those that occur in the semantics of standard logics; and individuals verify assertions on the basis of both facts and possibilities that did not occur.

This paper replies to Politzer’s (2007) criticisms of the mental model theory of conditionals. It argues that the theory provides a correct account of negation of conditionals, that it does not provide a truth-functional account of their meaning, though it predicts that certain interpretations of conditionals yield acceptable versions of the ‘paradoxes’ of material implication, and that it postulates three main strategies for estimating the probabilities of conditionals.

Strengthening the abilities of smallholder farmers in developing countries, particularly women farmers, to produce for both home and the market is currently a development priority. In many contexts, ownership of assets is strongly gendered, reflecting existing gender norms and limiting women’s ability to invest in more profitable livelihood strategies such as market-oriented agriculture. Yet the intersection between women’s asset endowments and their ability to participate in and benefit from agricultural interventions receives minimal attention. This paper explores changes in gender relations (...) and women’s assets in four agricultural interventions that promoted high value agriculture with different degrees of market-orientation. Findings suggest that these dairy and horticulture projects can successfully involve women and increase production, income and the stock of household assets. In some cases, women were able to increase their control over production, income and assets; however in most cases men’s incomes increased more than women’s and the gender-asset gap did not decrease. Gender- and asset-based barriers to participation in projects as well as gender norms that limit women’s ability to accumulate and retain control over assets both contributed to the results. Comparing experiences across the four projects, especially where projects implemented adaptive measures to encourage gender-equitable outcomes, provides lessons for gender-responsive projects targeting existing and emerging value chains for high value products. Other targeted support to women farmers may also be needed to promote their acquisition of the physical assets required to expand production or enter other nodes of the value chain. (shrink)

The earlier volume in this series dealt with two religions of Indian origin, namely, Buddhism and Jainism. The Indian religious scene, however, is characterized by not only religions which originated in India but also by religions which entered India from outside India and made their home here. Thus religious life in India has been enlivened throughout its history by the presence of religions of foreign origin on its soil almost from the very time they came into existence. This volume covers (...) three such religions—Zoraoastrianism, Judaism, and Islam. In the case of Zoraostianism, even its very beginnings are intertwined with India, as Zoroastrianism reformed a preexisting religion which had strong links to the Vedic heritage of India. This relationship took on a new dimension when a Zoroastrian community, fearing persecution in Persia after its Arab conquest, sought shelter in western India and ultimately went on to produce India’s pioneering nationalist in the figure of Dadabhai Naoroji ( 1825-1917), also known as the Grand Old Man of India. Jews found refuge in south India after the destruction of the Temple by the Romans in 70 C.E. and have remained a part of the Indian religious scene since then, some even returning to Israel after it was founded in 1948. Islam arrived in Kerala as soon as it was founded and one of the earliest mosques in the history of Islam is found in India. Islam differs from the previously mentioned religions inasmuch as it went on to gain political hegemony over parts of the country for considerable periods of time, which meant that its impact on the religious life of the subcontinent has been greater compared to the other religions. It has also meant that Islam has existed in a religiously plural environment in India for a longer period than elsewhere in the world so that not only has Islam left a mark on India, India has also left its mark on it. Indeed all the three religions covered in this volume share this dual feature, that they have profoundly influenced Indian religious life and have also in turn been profoundly influenced by their presence in India.

Previous research has found that more embodied insults are identified faster and more accurately than less embodied insults. The linguistic processing of embodied compliments has not been well explored. In the present study, participants completed two tasks where they identified insults and compliments, respectively. Half of the stimuli were more embodied than the other half. We examined the late positive potential component of event-related potentials in early, middle, and late time windows. Increased embodiment resulted in improved response accuracy to compliments (...) in both tasks, whereas it only improved accuracy for insults in the compliment detection task. More embodied stimuli elicited a larger LPP than less embodied stimuli in the early time window. Insults generated a larger LPP in the late time window in the insult task; compliments generated a larger LPP in the early window in the compliment task. These results indicate that electrophysiological correlates of emotional language perception are sensitive to both top-down and bottom-up processes. (shrink)

Nietzsche’s Anti-Darwinism. By Dirk R. Johnson (Cambridge: Cambridge University Press, 2010) In this substantial and incisive monograph, Dirk R. Johnson traces in minute detail Nietzsche’s stance towards Darwin at the various stages of his intellectually productive life. Johnson’s book is in two principal parts: Part 1 is on Nietzsche’s early Darwinism, which turned into anti-Darwinism, and Part 2 is a close reading of all three essays of Nietzsche’s Genealogy of Morals in their historical context since together they (...) constitute “his most systematic, thorough, and far-reaching analysis of the theories of Darwin and their followers” (81, 111). The author concedes that Nietzsche’s exchange with Darwin (1809–82), who was a contemporary of Nietzsche (1944–1900), is often implicit only and that he leads his explicit discussions of Darwin mostly in his unpublished notebooks. I agree with Johnson’s view that Nietzsche knew Darwin’s thought and its implications both “early and well’ (3). Johnson provides compelling evidence of the “increased personalization” of Nietzsche’s opposition to Darwinism during his last productive years after Zarathustra. For instance, Nietzsche entitled section 9,14 of Twilight of the Idols “Anti-Darwin,” and explained that “his position at this stage resulted both from his critical reappraisal of Darwin’s genealogical perspectives in the middle period and his attempt in Zarathustra to define the parameters of an affirmative, anti-metaphysical vision beyond Darwinism” (79). He argues that Zarathustra trans-values Darwinian categories such as “reason.” For him, “the work’s literary self-expression is the message,” since the superior well-being of the future higher type “can only be conjured through poetic affirmation” (48, 50).

In lieu of an abstract, here is a brief excerpt of the content:Philosophy of Music Education Review 11.2 (2003) 130-140 [Access article in PDF] Western Classical Music and General Education Estelle R. Jorgensen Indiana University Thinking about transforming music, I address issues relating to the role of musicians in higher education and Western classical music in general education. I am concerned about this music because it is marginalized in general education and the civic spaces of public life. Where once it (...) held a privileged place, it seems now to have acquired (in some quarters at least) a negative connotation as a bastion of elitism and privilege. Instead, popular musics (with a nod to musics of other cultures) have pride of place in much elementary and secondary music education and in many university and college offerings designed for students whose principal fields of study lie outside music. An all-too-common musical illiteracy or, at best, elementary level of musical literacy and aurality renders Western classical music inaccessible to the general public just as the pervasiveness of popular music renders it inaudible and invisible. Bridges to past, less accessible, and esoteric traditions are also too few or in disrepair. Julian Johnson laments the diminished stature of Western classical music and argues for its values in today's world. 1Music teachers of all stripes urgently need to address this marginalization of Western classical music as a matter of public policy. If caring for and fostering [End Page 130] diversity in the natural world is a good, then it is reasonable to expect that fostering diversity in the cultural world is likewise a good. If preventing the extinction of natural species is a matter of public policy, then surely preventing the extinction of musics among other cultural traditions is at least as important. Social transformation has within it the seeds of conservation, or the preserving of past traditions, just as it also suggests profound and ongoing planned and unintended change. When any music such as Western classical music is sidelined, music education policy makers need to ask, Is this multi-cultural, multi-ethnic, multi-faceted music important to keep, foster, and change? What does it have to contribute in the present world? Is it being cared for sufficiently? If it needs to change, how ought it be changed? What principles can be helpful to music teachers in caring for, fostering, and changing it? These are compelling public policy questions for our time. A Quarrel and Its Aftermath In 1963, participants in the Yale Seminar asked some of these very difficult questions of music education policy makers. MENC leaders took exception to the seminar and its conclusions; although some outstanding music teachers were participants, the organization had not been invited and the seminar was not its idea. 2 Instead of addressing directly some of the important criticisms of school music education and music teacher education raised in the seminar, the MENC mounted its own rival Tanglewood Symposium in 1967. Participants in this symposium faulted music in higher education for its failure to admit "talented and capable high school music students [to] the privilege of advanced study," the "[c]ompartmentalization and lack of communication between various segments of the music field," its lack of relation to "the musical heritage of American culture," and its failure to ensure arts courses in general education. 3 The symposium contributed to a populist stance focused on the myriad vernacular traditions of the world, thereby diminishing the role and presence of Western classical music and highlighting popular and vernacular musics at MENC conferences and in the elementary and secondary schools in the United States. Subsequent attempts to renew the Western classical tradition and raise the musical expectations of teachers and their students in the nation's schools exemplified in the Juilliard Repertory, Manhattanville Music Curriculum Project, and Comprehensive Musicianship Program seem not to have made a lasting impact. And the differing criticisms and visions of the Yale Seminar and Tanglewood Symposium have yet to be critically engaged.Summarizing criticisms made of school music repertoire in the report of the Yale Seminar to the Office of Education, U.S. Department of Health, Education, and...

Pursuing Justice in Africa focuses on the many actors pursuing many visions of justice across the African continent--their aspirations, divergent practices, and articulations of international and vernacular idioms of justice. The essays selected by editors Jessica Johnson and George H. Karekwaivanane engage with topics at the cutting edge of contemporary scholarship across a wide range of disciplines. These include activism, land tenure, international legal institutions, and post-conflict reconciliation. Building on recent work in sociolegal studies that foregrounds justice over and (...) above concepts such as human rights and legal pluralism, the contributors grapple with alternative approaches to the concept of justice and its relationships with law, morality, and rights. While the chapters are grounded in local experiences, they also attend to the ways in which national and international actors and processes influence, for better or worse, local experiences and understandings of justice. The result is a timely and original addition to scholarship on a topic of major scholarly and pragmatic interest. Contributors: Felicitas Becker, Jonathon L.

This paper employs Ruth Millikan’s biosemantic theory of representation to develop a proposal about the function of ethical claims and judgments. I propose that ethical claims and judgments (or ethical ‘affirmations’) have the function of simultaneously tracking the morally salient features of social situations and directing behavior that coordinates in a collectively beneficial way around those features. Thus, ethical affirmations count as a species of what Millikan labels ‘Pushmi-Pullyu’ representations that simultaneously have a descriptive and a directive direction of (...) fit. This proposal supports a version of motivational internalism that can accommodate a surprising range of actual failures of motivation. I also briefly situate this proposal in the metaethical literature, contrasting it with other hybrid views incorporating elements of cognitivism and expressivism. (shrink)

The human race is an ongoing entity, not just a collection of individuals. It has interests which are not just the aggregated interests of individual humans. These interests are morally significant and have important implications for environmental ethics.

This book provides an analysis of the debate surrounding cultural diversity, and attempts to reconcile the seemingly opposing views of "ethical imperialism," the belief that each individual is entitled to fundamental human rights, and cultural relativism, the belief that ethics must be relative to particular cultures and societies. The author examines the role of cultural tradition, often used as a defense against critical ethical judgments. Key issues in health and medicine are explored in the context of cultural diversity: the physician-patient (...) relationship, disclosing a diagnosis of a fatal illness, informed consent, brain death and organ transplantation, rituals surrounding birth and death, female genital mutilation, sex selection of offspring, fertility regulation, and biomedical research involving human subjects. Among the conclusions the author reaches are that ethical universals exist, but must not be confused with ethical absolutes. The existence of ethical universals is compatible with a variety of culturally relative interpretations, and some rights related to medicine and health care should be considered human rights. Illustrative examples are drawn from the author's experiences serving on international ethical review committees and her travels to countries in Africa, Asia, and Latin America, where she conducted educational workshops and carried out out her own research.

The central aim of this book is to answer two questions: Are alternatives for choice ever incomparable? and, In what ways can items be compared? The arguments offered suggest that alternatives for choice no matter how different are never incomparable, and that the ways in which items can be compared are richer and more varied than commonly supposed. This work is the first book length treatment of the topics of incomparability, value, and practical reason.

In this major new work by one of the leading writers on Utopian Studies, Ruth Levitas argues that a prospective future of ecological and economic crises poses a challenge to the utopian imaginary, to conceive a better world and alternative future. Utopia as Method does not construe utopia as goal or blueprint, but as a holistic, reflexive method for developing what those possible futures might be. It begins by treating utopia as the quest for grace, through a hermeneutics that (...) recovers the utopian meaning in our culture, explored through colour and music. Moving from the existential to the social, it draws on H.G. Wells's claim that the creation of utopias is the distinctive and proper method of sociology, and on the tentative reappearance of utopia in contemporary social theory. It proposes a constructive method, the Imaginary Reconstitution of Society. This fusion of explicitly normative social theory and analytic critique rehabilitates utopia as an integral part of sociology, and offers a means of collective engagement in shaping a better tomorrow."--Publisher's description.

In recent years, emotions have become a major, vibrant topic of research not merely in the biological and psychological sciences but throughout a wide swath of the humanities and social sciences as well. Yet, surprisingly, there is still no consensus on their basic nature or workings. Ruth Leys’s brilliant, much anticipated history, therefore, is a story of controversy and disagreement. The Ascent of Affect focuses on the post–World War II period, when interest in emotions as an object of study (...) began to revive. Leys analyzes the ongoing debate over how to understand emotions, paying particular attention to the continual conflict between camps that argue for the intentionality or meaning of emotions but have trouble explaining their presence in non-human animals and those that argue for the universality of emotions but struggle when the question turns to meaning. Addressing the work of key figures from across the spectrum, considering the potentially misleading appeal of neuroscience for those working in the humanities, and bringing her story fully up to date by taking in the latest debates, Leys presents here the most thorough analysis available of how we have tried to think about how we feel.

It has been almost eighty years since Paul Dirac delivered a lecture on the relationship between mathematics and physics and since 1960 that Eugene Wigner wrote about the unreasonable effectiveness of mathematics in the natural sciences. The field of cosmology and efforts to define a more comprehensive theory have changed significantly since the 1960s; thus, it is time to refocus on the issue. This paper expands on ideas addressed by these two great physicists, specifically, the ultimate effectiveness of mathematics to (...) describe nature. After illustrating how theoretical physic predicted discoveries, the concepts of established theories are summarized. Then, the “world equation” which combines all key physics theories is conceptually described. As the possible last piece of the puzzle, String Theory is briefly defined. And last, a cursory overview of an extreme proposal is presented — the world as a mathematical object. However, there is no fundamental reason to believe that math will allow mankind to completely comprehend nature. If math does not provide a comprehensive theory, nature will retain her secrets.
