Learning to use new technologies often involves significant challenges for teachers and learners. This study follows Tally's (( 2007 ). Digital technology and the end of social studies education. Theory & Research in Social Education, 35(2), 305–321) challenge to put the “why” of social studies education first, and then “tinker” with technologies to discover how they can address learning goals. Using a modified “backward design” approach ( Wiggins & McTighe (2005). Understanding by design. ASCD), a design team of middle school (...) teachers, researchers, and disciplinary experts designed, enacted, and studied historical inquiry projects in middle school and college classrooms. Students used online, interactive, historical census data GIS “webmaps” ( Baker (2005). Internet-Based GIS Mapping in Support of K-12 Education. The Professional Geographer, 57(1), 44–50) to investigate African American and Latino migrations. The study presents findings detailing three emergent learning objectives, highlighting how students’ presentations with GIS maps evidenced three modes of reasoning with webmaps: (1) making observations with data; (2) drawing inferences from data; and (3) explaining the limitations of data for inquiry.

The identity predicate can be defined using second-order quantification: a=b =df ∀F(Fa↔Fb). Less familiarly, a dyadic sentential operator analogous to the identity predicate can be defined using third-order quantification: ϕ≡ψ =df ∀X(Xϕ↔Xψ), where X is a variable of the same syntactic type as a monadic sentential operator. With this notion in view, it is natural to ask after general principles governing its application. More grandiosely, how fine-grained is reality? -/- I will argue that reality is not structured in anything like (...) the way that the sentences we use to talk about it are structured. I do so by formulating a higher-order analogue of Russell’s paradox of structured propositions. I then relate this argument to the Frege-Russell correspondence. When confronted with the alleged paradox, Frege agreed that reality was not structured, but maintained that propositions (i.e. thoughts) were structured all the same. Russell replied that his paradox showed Frege’s theory of structured thoughts to be inconsistent, to which Frege replied that Russell’s argument failed to heed the distinction between sense and reference. Most recent commentators have sided with Russell. In defense of Frege, I establish the consistency of one version of his rejoinder. I then consider and reject some ways of resisting the argument against a structured conception of reality. I conclude that, if propositions are structured, this is because they correspond not to distinctions in reality, but rather to ways in which those distinctions can be represented. (shrink)

It's often said that according to deflationary theories of truth, truth is not a ‘substantial’ property. While this is a fine slogan, it is far from transparent what deflationists mean (or ought to mean) in saying that truth is ‘insubstantial’. Focusing so intently upon the concept of truth and the word ‘true’, I argue, deflationists and their critics have been insufficiently attentive to a host of metaphysical complexities that arise for deflationists in connection with the property of truth. My aim (...) is to correct several misunderstandings as to what deflationists are after here—including some harboured by deflationists themselves—and to offer an account of the commitments about truth's nature that they ought to undertake. In developing this account, I focus particularly upon the issue of what metaphysics of truth a Horwichian minimalist ought to adopt. (shrink)

Sweatshop labor is often cited as an example of the worst and most pervasive form of exploitation today, yet understanding what is meant by the charge has proven surprisingly difficult for philosophers. I develop an account of what I call “Needs Exploitation,” grounded in a specification of the duty of beneficence. In the case of sweatshop labor, I argue that employers face a duty to extend to employees a wage sufficient to meet their basic needs. This duty is limited by (...) the degree of the employees’ dependence on the employer for basic needs and a reasonability standard where the employer may remain within a range of well-being between deficiency and luxury.

The epsilon calculus is a logical formalism developed by David Hilbert in the service of his program in the foundations of mathematics. The epsilon operator is a term-forming operator which replaces quantifiers in ordinary predicate logic. Specifically, in the calculus, a term εx A denotes some x satisfying A(x), if there is one. In Hilbert's Program, the epsilon terms play the role of ideal elements; the aim of Hilbert's finitistic consistency proofs is to give a procedure which removes such terms (...) from a formal proof. The procedures by which this is to be carried out are based on Hilbert's epsilon substitution method. The epsilon calculus, however, has applications in other contexts as well. The first general application of the epsilon calculus was in Hilbert's epsilon theorems, which in turn provide the basis for the first correct proof of Herbrand's theorem. More recently, variants of the epsilon operator have been applied in linguistics and linguistic philosophy to deal with anaphoric pronouns. (shrink)

I discuss various formulations of stochastic Einstein locality (SEL), which is a version of the idea of relativistic causality, that is, the idea that influences propagate at most as fast as light. SEL is similar to Reichenbach's Principle of the Common Cause (PCC), and Bell's Local Causality. My main aim is to discuss formulations of SEL for a fixed background spacetime. I previously argued that SEL is violated by the outcome dependence shown by Bell correlations, both in quantum mechanics and (...) in quantum field theory. Here I reassess those verdicts in the light of some recent literature which argues that outcome dependence does not violate the PCC. I argue that the verdicts about SEL still stand. Finally, I briefly discuss how to formulate relativistic causality if there is no fixed background spacetime. (shrink)

We report a series of experiments carried out with Palestinian and Israeli participants showing that violent opposition to compromise over issues considered sacred is increased by offering material incentives to compromise but decreased when the adversary makes symbolic compromises over their own sacred values. These results demonstrate some of the unique properties of reasoning and decision-making over sacred values. We show that the use of material incentives to promote the peaceful resolution of political and cultural conflicts may backfire when adversaries (...) treat contested issues as sacred values.

As the most prominent initiative in the open education movement, the Massive Open Online Course is often claimed to disrupt established educational models through the use of innovative technologies that overcome geographic and economic barriers to higher education. However, this paper suggests that the MOOC project, as a typical example of initiatives in this field, fails to engage with a theory of the subject. As such, uncritical and problematic forms of humanism tend to be assumed in the promotion and delivery (...) of these courses: the expectation of rational and self-directing individuals, with a universal desire for education. This fundamental orthodoxy limits both the understanding of technology and the possibilities for a concept of ‘openness’ in education. Given the global scale of the MOOC, and its high-profile associations with elite universities, the need for critical alternatives is pressing. In this paper I draw on critical posthumanism—an umbrella term for a range of philosophical and theoretical positions—for two purposes. Firstly and principally as a perspective through which to critique the educational reliance on humanism that is maintained in the project of the MOOC, and secondly to suggest alternative frameworks for thinking about the intermingling of humans and technologies in education. Space and time are considered as the two principal sites with which technological change is realised, and the promotion of the MOOC is shown to mask spatial and temporal conditions through adherence to an underlying humanist framework.

I investigate the role of geometric intuition in Frege’s early mathematical works and the significance of his view of the role of intuition in geometry to properly understanding the aims of his logicist project. I critically evaluate the interpretations of Mark Wilson, Jamie Tappenden, and Michael Dummett. The final analysis that I provide clarifies the relationship of Frege’s restricted logicist project to dominant trends in German mathematical research, in particular to Weierstrassian arithmetization and to the Riemannian conceptual/geometrical tradition at Göttingen. (...) Concurring with Tappenden, I hold that Frege’s logicism should not be understood as a continuing a project of reductionist arithmetization. However, Frege does not quite take up the Riemannian banner either. His logicism supports a hierarchical understanding of the structure of mathematical knowledge, according to which arithmetic is applicable to geometry but not vice versa because the former is more general, as revealed by the strictly logical nature of its objects in comparison to the intuitional nature of geometric objects. I suggest, in particular, that Frege intended that foundational work would show the use of geometric intuition in complex analysis, a source of error for Riemann that Weierstrass was proud to have uncovered, to be inessential.

Predicates of personal taste have attracted a great deal of attention from philosophers of language and linguists. In the intricate debates over PPT, arguably the most central consideration has been which analysis of PPT can best account for the possibility of faultless disagreement about matters of personal taste. I argue that two models of such disagreement—the relativist and absolutist models—are empirically inadequate. In their stead, I develop a model of faultless taste disagreement which represents it as involving a novel incompatibility (...) relation between preferences that I call type-noncotenability. This model is available to all parties in the ongoing debates about PPT, but it points up an advantage enjoyed by expressivist accounts of PPT. In closing, I consider four objections against the model that, while failing to fully undermine it, open up promising avenues of inquiry about the nature of disagreement. (shrink)

One important strand of Sellars’s attack on classical foundationalism from Empiricism and the Philosophy of Mind is his thesis about the priority of is-talk over looks-talk. This thesis has been criticized extensively in recent years, and classical foundationalism has found several contemporary defenders. I revisit Sellars’s thesis and argue that is-talk is epistemically prior to looks-talk in a way that undermines classical foundationalism. The classical foundationalist claims that epistemic foundations are constituted by the agent’s set of looks-judgments. However, I argue (...) that only a subset of these looks-judgments are even candidates to serve as foundations for the agent’s empirical knowledge, and membership in this subset is determined by the agent’s theory of how the world is. Thus, the epistemic force of the looks-judgments in this subset is dependent on the agent’s theory of how the world is. This means that these looks-judgments aren’t foundational at all, as the agent’s theory of how the world is is epistemically is prior to the epistemic status of these looks-judgments. This is the sense in which judgments about how the world is are epistemically prior to judgments about how things look. This conclusion allows concrete elaboration of another of Sellars’s well-know claims: “I do wish to insist that the metaphor of ‘foundation’ is misleading in that it keeps us from seeing that if there is a logical dimension in which other empirical propositions rest on observation reports, there is another logical dimension in which the latter rest on the former”.

Despite a significant amount of literature debating the efficiency of high-risk pools in health insurance, dramatically less has been written about their normative implications. The present article takes the route less traveled by setting aside the question of efficiency to argue that the use of high-risk pools creates some serious normative concerns. The article explores these concerns by dividing them on two fronts. First, as regards the social-recognitional status of those who are forced into the high-risk pool. Second, as regards (...) a general concern of distributive justice, namely fairness in access to resources. The author argues that regardless of the veracity of arguments which laud the efficiency of high-risk pools, their use in health insurance is unjust because of the herein explained implications for social recognition and distributive justice.

"Arguing that debates over legitimacy, political violence, freedom, and justice would benefit greatly from cross-tradition theorizing, this book shows how putting analytic and continental political theory in conversation would help us to overcome these intractable problems"--.

ABSTRACT:In this response, I reiterate my argument that price gouging undercuts the goal of equity in access to essential goods whereas Zwolinski emphasizes the importance of the efficient provision of essential goods above all other goals. I agree that the efficient provision of essential goods is important as I argue for the goal of equitable access to sufficient of the goods essential to living a minimally flourishing human life. However, efficiency is a means to this goal rather than the end (...) itself. Finally, I offer additional arguments against the non-worseness claim. (shrink)

Many psychological studies of categorization and reasoning use undergraduates to make claims about human conceptualization. Generalizability of findings to other populations is often assumed but rarely tested. Even when comparative studies are conducted, it may be challenging to interpret differences. As a partial remedy, in the present studies we adopt a 'triangulation strategy' to evaluate the ways expertise and culturally different belief systems can lead to different ways of conceptualizing the biological world. We use three groups (US bird experts, US (...) undergraduates, and ordinary Itza' Maya) and two sets of birds (North American and Central American). Categorization tasks show considerable similarity among the three groups' taxonomic sorts, but also systematic differences. Notably, US expert categorization is more similar to Itza' than to US novice categorization. The differences are magnified on inductive reasoning tasks where only undergraduates show patterns of judgment that are largely consistent with current models of category-based taxonomic inference. The Maya commonly employ causal and ecological reasoning rather than taxonomic reasoning. Experts use a mixture of strategies (including causal and ecological reasoning), only some of which current models explain. US and Itza' informants differed markedly when reasoning about passerines (songbirds), reflecting the somewhat different role that songbirds play in the two cultures. The results call into question the importance of similarity-based notions of typicality and central tendency in natural categorization and reasoning. These findings also show that relative expertise leads to a convergence of thought that transcends cultural boundaries and shared experiences. (shrink)

Physicians place significant weight on the distinction between acts and omissions. Most believe that autonomous refusals for procedures, such as blood transfusions and resuscitation, ought to be respected, but they feel no similar obligation to accede to requests for treatment that will, in the physician’s opinion, harm the patient (e.g., assisted death). Thus, there is an asymmetry. In this paper, we challenge the strength of this distinction by arguing that the ordering of values should be the same in both cases. (...) The reason for respecting refusals is that, in such cases, autonomy outweighs well-being. We argue that the same should be true in request cases, which means that requests should not be denied only due to the treatment being too harmful in the physician’s opinion. Our strategy is to consider and reject a number of arguments for the asymmetrical view, including an appeal to the doing–allowing distinction and positive and negative rights. The duty to respect refusals is still greater than the duty to grant requests on our view, but, by arguing that the ordering of values is the same in both cases, we show that there is less of a distinction in healthcare between requests and refusals than many currently believe.

Acentral promise of human embryonic stem cell research is the potential to develop viable therapeutic approaches to a range of devastating diseases and conditions. Despite excitement over such advances, there are scientific and medical reasons to be cautious as stem cells and their products are introduced into patients. In response to such concerns, the International Society for Stem Cell Research as well as ad hoc groups and individuals have offered approaches to governance of this research. While there are similarities among (...) these governance models and they are in principle easily endorsable, in this paper I raise a set of concerns related to their implementation, suggesting areas where gathering data may facilitate more appropriate oversight. Next, I suggest areas that seem to have been neglected as these governance models have been developed so that they may be on the agendas of those seeking to revise these models in the future. Finally, I describe how some of the concerns that have arisen in considering the appropriate governance of stem cell research may be useful in science and translational research more broadly.

Introduction, by C.K. Ogden.--The theory of fictions, by Jeremy Bentham.

In The Crane's Walk, Jeremy Barris seeks to show that we can conceive and live with a pluralism of standpoints with conflicting standards for truth--with the truth of each being entirely unaffected by the truth of the others. He argues that Plato's work expresses this kind of pluralism, and that this pluralism is important in its own right, whether or not we agree about what Plato's standpoint is.The longest tradition of Plato scholarship identifies crucial faults in Plato's theory of (...) Ideas. Barris argues that Plato deliberately displayed those faults, because he wanted to demonstrate that basic kinds of error or illogic have dimensions that are crucial to the establishing of truth. These dimensions legitimate a paradoxical coordination of logically incompatible conceptions of truth. Connecting this idea with emerging currents of Plato scholarship, he emphasizes, in addition to the dialogues' arguments, the importance of their nonargumentative features, including drama, myths, fictions, anecdotes, and humor. These unanalyzed nonargumentative features function rigorously, as a lever with which to examine the enterprise of rational argument itself, without presupposing its standards or illegitimately assimilating any position to the standards of another.Today, communities are torn apart by conflicts within and between a host of different pluralist and absolutist commitments. The possibility developed in this book-a coordination of absolute and relative truth that allows an understanding of some relativist and some absolutist positions as being fully legitimate and as capable of existing in a relation to their opposites-may contribute to perspectives for resolving these conflicts.

Many nations in the developing world invest scarce funding into training health workers. When these workers migrate to richer countries, particularly when this migration occurs before the source community can recoup the costs of training, the destination community realizes a net gain in resources by obtaining the workers' skills without having to pay for their training. This effect of health worker migration has frequently been condemned as 'poaching' or a case of theft. I assess the charge that the rich nations (...) of the world poach the resources of the developing world through the active recruitment of migrants. I argue that the charge of poaching is misguided in these cases. The misuse of the term poaching is particularly troubling as it distracts attention away from the many actual moral wrongs taking place through the process of health worker migration and objectifies health workers.

Abstract:Recently, the idea that every hypothetical imperative must somehow be ‘backed up’ by a prior categorical imperative has gained a certain influence among Kant interpreters and ethicists influenced by Kant. Since instrumentalism is the position that holds that hypothetical imperatives can by themselves and without the aid of categorical imperatives explain all valid forms of practical reasoning, the influential idea amounts to a rejection of instrumentalism as internally incoherent. This paper argues against this prevailing view both as an interpretation of (...) Kant and as philosophical understanding of practical reason. In particular, it will be argued that many of the arguments that claim to show that hypothetical imperatives must be backed up by categorical imperatives mistakenly assume that the form of practical reasoning must itself occur as a premise within the reasoning. An alternative to this assumption will be offered. I will conclude that while instrumentalism may well be false, there is no reason to believe it is incoherent. (shrink)

Critical notice of Paul Faulkner, "Knowledge on Trust" (OUP 2011) and Benjamin McMyler, "Testimony, Trust, and Authority" (OUP 2011).

Sometimes Always True aims to resolve, through a re-understanding of the nature of sense, three connected problems central to philosophical thought: that genuine pluralism must make room for outlooks that exclude pluralism, that philosophy ultimately explores sense as a whole and so must in some way step outside of sense, and that our experience of the deep questions of life therefore similarly involves suspensions of sense itself.

A critical edition of three works of Bentham, Deontology and The Article on Utilitarianism were previously unpublished. Together with An Introduction to the Principles of Morals and Legislation, they provide a comrehensive exposition of Bentham's views. Based entirely on manuscripts by Bentham of his amanuenses, this edition's full introduction linking the three works. Each work is supplemented with detailed and critical notes.

This article is an investigation into G. E. M. Anscombe's suggestion that there can be cases where belief takes a personal object, through an examination of the role that the activity of teaching plays in Anscombe's discussion. By contrasting various kinds of ‘teachers’ that feature in her discussion, it is argued that the best way of understanding the idea of believing someone personally is to situate the relevant encounter within the social, conversational framework of ‘engaged reasoning’. Key features of this (...) framework are highlighted, and are used to characterise the distinctive kind of teaching and learning germane to Anscombe's suggestion. (shrink)

We describe how we used the interactive theorem prover Isabelle to formalise and check the laws of the Timed Interval Calculus (TIC). We also describe some important corrections to, clarifications of, and flaws in these laws, found as a result of our work.

This essay considers the special character of mathematical reasoning, and draws on observations from interactive theorem proving and the history of mathematics to clarify the nature of formal and informal mathematical language. It proposes that we view mathematics as a system of conventions and norms that is designed to help us make sense of the world and reason efficiently. Like any designed system, it can perform well or poorly, and the philosophy of mathematics has a role to play in helping (...) us understand the general principles by which it serves its purposes well.

Medical tourism (MT) can be conceptualized as the intentional pursuit of non-emergency surgical interventions by patients outside their nation of residence. Despite increasing popular interest in MT, the ethical issues associated with the practice have thus far been under-examined. MT has been associated with a range of both positive and negative effects for medical tourists' home and host countries, and for the medical tourists themselves. Absent from previous explorations of MT is a clear argument of how responsibility for the harms (...) of this practice should be assigned. This paper addresses this gap by describing both backward looking liability and forward looking political responsibility for stakeholders in MT. We use a political responsibility model to develop a decision-making process for individual medical tourists and conclude that more information on the effects of MT must be developed to help patients engage in ethical MT.

Much recent work in the study of popular culture has emphasized the extent to which it is not only a site of signifying practices, myths, meanings and identifications, but also an arena of intensities, of affective flows and corporeal state-changes. From this perspective, many areas of popular culture (from calisthenics to social dance to video gaming) can be seen as sites at which rich and complex—if sometimes dangerous—processes of embodied learning/teaching take place. By comparison, the world of formal education can (...) seem hopelessly clumsy in its inattention to such issues. From a personal perspective, I can attest that nothing surprises my students more than when I try to get them to think about the ergonomics of studying, or advise them that getting some exercise and cutting down on sugar will probably improve their work as much as further studying will, or when I advise graduate students that their mood and physical state will make as much difference to the quality of their lectures as will their level of formal preparation; and yet experience has convinced me of the accuracy of these assertions. I would aver that I have learned more about successful lecturing—in particular about the improvisational skill of ‘reading’ a room, and adjusting an affective–informational flow accordingly—from DJing in dance clubs than from any formal training in pedagogy that I have received. What conclusions could be drawn from these observations, and how do they relate to existing strands of pedagogic theory? These are the questions which this article will ultimately seek to address.

We consider the extent to which one can compute bounds on the rate of convergence of a sequence of ergodic averages. It is not difficult to construct an example of a computable Lebesgue measure preserving transformation of [0, 1] and a characteristic function f = χA such that the ergodic averages Anf do not converge to a computable element of L2([0, 1]). In particular, there is no computable bound on the rate of convergence for that sequence. On the other hand, (...) we show that, for any nonexpansive linear operator T on a separable Hilbert space and any element f , it is possible to compute a bound on the rate of convergence of Anf from T , f , and the norm f ∗ of the limit. In particular, if T is the Koopman operator arising from a computable ergodic measure preserving transformation of a probability space X and f is any computable element of L2 (X ), then there is a computable bound on the rate of convergence of the sequence Anf.

It is now commonplace for governments in Western countries to require the unemployed to work in exchange for their unemployment benefits. In this article I raise some serious doubts about the most promising and philosophically interesting defence of this argument, which relies on the ‘principle of reciprocity’.

I do this by reconstructing the arguments (...) for the obligations of the unemployed put forward in both the United Kingdom and Australia. (shrink)
