Why was the South African state so much more successful than the Brazilian state in its attempts to collect income taxes during the twentieth century? Nationally distinctive tax policies and patterns of administration can be explained by examining the impact of contrasting definitions of National Political Community, specified in critical constitutions written around the turn of the century. The ways in which racial and spatial cleavages were addressed in the 1891 Brazilian constitution and the 1909 South Africa Act influenced the (...) development of interclass and intraclass relations, which in turn affected the willingness of upper-income groups to accept state demands for income tax payments. Varied patterns of state development were largely predicated on contested notions of “us” and “them.”. (shrink)

As physicians, we should join our medical colleagues in carefully but persistently telling the scientific, medical truth. As psychiatrists, we should bring psychiatric knowledge into the discussion, for example, by explaining what can happen when people who do not, apparently, have a diagnosable mental disorder interact under stress with other people who, apparently, do.Delirium is a clinical diagnosis, made when characteristic signs and symptoms are present which should not be made ‘by exclusion’ when, as may happen, other causes are not found.

In this volume, noted philosopher Lenn E. Goodman shares the insights gained over a lifetime of pondering the meaning and purpose of Maimonides' celebrated Guide to the Perplexed. Written in the late twelfth century, Maimonides' Guide aims to help religiously committed readers who are alive to the challenges posed by reason and the natural sciences to biblical and rabbinic tradition. Keyed to the new translation and commentary by Lenn E. Goodman and Phillip I. Lieberman, this volume follows Maimonides' life (...) and learning and delves into the text of the Guide, clearly explaining just what Maimonides means by identifying the Talmudic Ma'aseh Bereshit and Ma'aseh Merkavah with physics and metaphysics (to Maimonides, biblical cosmology and theology). Exploring Maimonides' treatments of revelation, religious practice and experience, law and ritual, the problem of evil, and the rational purposes of the commandments, this guide to the Guide explains the tactics Maimonides deployed to ensure that readers not get in over their heads when venturing into philosophical deep waters.

In lieu of an abstract, here is a brief excerpt of the content:On Scheeben's Place in Nineteenth-Century Catholic Theology and the Question of His Theological MethodEvan S. KoopMatthias Joseph Scheeben (1835–1888) is enjoying a moment in English-speaking Catholic theological circles. In recent years his thought has attracted increasing interest from scholars who view him as an important forerunner to some of the central currents of Catholic theology in the twentieth century,1 a trend that promises only to accelerate with the recent (...) publication of the initial volumes of the first complete translation of his monumental Handbuch der katholischen Dogmatik into English.2 The much-debated question of Scheeben's proper place in the history of Catholic theology in the nineteenth century therefore, has gained a new relevance. While the present study of course, cannot and does not claim to bring this dispute to a definitive resolution, nevertheless it is hoped that it may at least help to clarify some common misunderstandings that can arise from hasty generalizations, and offer a few insights—which are not in fact new, but which are too often ignored by English-speaking scholars today—into the way in which the thought of the Jesuit theologians of the so-called "Roman School" may have served to influence Scheeben's unique theological method.In the past, numerous attempts have been made to situate Scheeben's thought within a particular theological school, and members of rival schools, in turn, have sought to claim him (or indeed repudiate him) as one of their [End Page 471] own.3 Amid the flood of divergent assessments of Scheeben's theological affinities, there at least exists some scholarly consensus about his greatness as a theologian. In 1935, during the centenary celebrations of Scheeben's birth, Pope Pius XI lauded him as a "man of genius" and proposed his thought to the students of the Germanicum as a model of the proper unity of theology's ascetical and dogmatic elements.4 In a Festschrift dedicated to Scheeben's theology published in the same year, Martin Grabmann judged that Scheeben was "the greatest dogmatic theologian of the nineteenth century,"5 and Carl Feckes, Scheeben's successor at the Cologne seminary, named him "the greatest Mariologist of our time."6 On the eve of the Second Vatican Council, no less an authority than Hans Urs von Balthasar could proclaim that Scheeben was "the greatest German theologian to-date [1961] since the time of Romanticism."7Nearly all, likewise, acknowledge the great difficulty of comprehending Scheeben's theology: even a German theologian of the stature of Joseph Ratzinger laments that Scheeben "has not made it easy, either as a professor for his hearers or as a writer for his readers. His language is rigorous, marked by the laborious travail of thought." The fact that he draws abundantly from such sources as Aquinas and the Greek Fathers "lends to his work [End Page 472] breadth and depth, but does not necessarily facilitate easy access."8 Similarly, the ultramontane Cardinal Henry Edward Manning, in his preface to an English abridgment of Scheeben's Dogmatik, warned that Scheeben's greatest work "requires not only reading but study; and study with patient care and conscientious desire to understand."9 Perhaps it is for this reason that it has become almost proverbial to observe that Scheeben's works are much praised, but seldom read.10Far less agreement, however, exists when it comes to the question of what kind of theologian Scheeben was, or to what theological school he belonged. Was he, asks the great Scheeben scholar Eugen Paul, "the prototype of those theologians who represent (if not establish) the infamous 'two-storey theory [Stockwerkstheorie] with respect to nature and grace—or does he rather belong to those who insist precisely on the transcendental unity of nature and grace?"11 Is Scheeben, in other words, a Neo-Scholastic, even "the most precious flower ever granted to the spring of Neo-Scholasticism,"12 as he was called in the first major study of his theology produced in the twentieth century? Or is he, instead, to be classed with the theologians of the Tübingen School who, under the influence of Romantic Idealism, sought to renew Catholic theology through... (shrink)

Over the past few years, a push to reverse the overall paltry state of science academies in the developing world has emerged as a central theme in numerous reports and has garnered the attention of a variety of organizations, including The National Academies in the United States. In particular, the establishment and maintenance of well-organized and functioning national academies of science throughout Africa is becoming an increasingly essential and crucial element of their overall prospects for development. Therefore, the purpose of (...) this article is to analyze the particular institutional traits and characteristics related to African science academies—including their small member-ships, lack of finances, little experience with policy advising, and worries about government backlash—and to argue that, because of these factors, these institutions must work to find suitable activities that will allow them to leverage whatever resources they do have to become effective policy advisors for government.

The experience of a reward appears to enhance memory for recent prior events, adaptively making that information more available to guide future decision-making. Here, we tested whether reward enhances memory for associative item-location information and also whether the effect of reward spreads to other categorically-related but unrewarded items. Participants earned either points (Experiment 1) or money (Experiment 2) through a time-estimation reward task, during which stimuli-location pairings around a 2D-ring were shown followed by either high-value or low-value rewards. All stimuli (...) were then tested for location memory or recognition (yes/no), immediately and after a 24-hour delay. Across both experiments (combined analysis), there was a robust improvement in location memory following high-value rewards, even though evidence supporting this effect was reliable in Experiment 2 but not in Experiment 1. The memory-enhancing effect of reward was observed on both the immediate and delayed location-memory tests. Reward-enhanced memory for both directly rewarded stimuli and categorically related stimuli that were not directly rewarded. No reliable effect of reward value on yes/no recognition-memory performance was observed in either experiment. We hypothesise that reward enhances the consolidation of recent experience and conceptually related memories to make these more available for future decisions. (shrink)

Despite the importance of commitment in moral and political philosophy, there has hitherto been little extended analysis of it. Marcel Lieberman examines the conditions under which commitment is possible, and offers at the same time an indirect argument for moral realism. He argues that realist evaluative beliefs are functionally required for commitment - especially regarding its role in self-understanding - and since it is only within a realist framework that such beliefs make sense, realism about values is a condition (...) for the possibility of commitment itself. His ambitious study addresses questions that are of great interest to analytic philosophers but also makes many connections with continental philosophy and with folk psychology, sociology and cognitive science, and will be seen as a distinctive intervention in the debate about moral realism.

In “The Immorality of Horror Films” (International Journal of Applied Philosophy 20:2 [2006], 278), Gianluca Di Muzio argues that it is immoral to produce, distribute, or watch so-called “slasher” or “gorefest” films. Though I am sympathetic, I don’t believe that his arguments warrant his conclusion. In this paper, I will respond to Di Muzio. In particular, I will focus on what I take to be his core argument, which is based on the idea that these films discourage morally appropriate reactions (...) to human suffering. Then I will examine two objections to Di Muzio’s position which he himself raises and dismisses, and I will argue that Di Muzio does not adequately refute either of the objections. Finally, I will conclude with some sympathetic remarks, and briefly consider what avenues we might pursue in order to argue for the immorality of at least some horror films. (shrink)

In this interesting book, Marcel Lieberman develops a novel and sustained argument for moral realism. He focuses on the psychological phenomenon of commitment, and argues that commitments psychologically require realist beliefs: paradigmatically, one cannot be committed to, say, social equality, without believing that social equality is genuinely valuable. In so arguing, he disagrees with those, on both sides of the debate over moral realism, who have argued that moral realism makes little practical difference. He draws on and criticizes a (...) number of important and influential figures, most particularly Rorty, Gibbard and Velleman, but his range of reference goes well beyond familiar figures in contemporary metaethics, taking in also inter alii Ricoeur, Gabriel Marcel, and rational expectations theorists in economics.

If some philosophers had not existed, the history of philosophy would have to invent them. After all, what would the introduction to philosophy teacher do without good old Berkeley, the notorious denier of common sense, or Hume, the infamous sceptic.

I don't mean to suggest that historians of philosophy have actually altered the past by bringing into being real flesh and blood philosophers.

On a prima facia reading, Zhuangzi seems to endorse some form of skepticism or relativism. This seems at odds with Zhuangzi as one of the two main sources of classical Daoism, considering the ideals of virtue and self-development promoted by that philosophy. However, Zhuangzi’s metaphorical and allegorical style lends itself to a number of interpretations of his epistemology, as well as the kind of self-knowledge and ethical development it might allow. A survey of the relevant literature shows that the epistemological (...) debate is not easily solvable, but by narrowing the range of interpretations, a coherent picture of his ethics begins to emerge, one in which some form of knowledge, especially self-knowledge, is still possible, as is an ethics of self-actualization.

Using a fictional but representative general practice consultation, involving the diagnosis of irritable bowel syndrome in a patient who is anxious for some relief from the discomfort his condition entails, this paper argues that when both a drug fails to out-perform placebo and the condition in question is a functional illness with no demonstrable underlying pathology, then the action of the drug is not only no better than placebo, and it is also no different from it either. The paper also (...) argues that, in the circumstances of the consultation described, it is striking that current governance deems it ethical for a practitioner to prescribe either a drug or a placebo, both of which appear to rely for their effectiveness on a measure of concealment on the part of the doctor, yet deems it unethical for a practitioner openly to prescribe a harmless and enjoyable substance which is likely to be no less effective than either drug or placebo and is also likely to be better-tolerated and cheaper than the drug.

In recent years, there has been a heated debate about how to interpret findings that seem to show that humans rapidly and automatically calculate the visual perspectives of others. In the current study, we investigated the question of whether automatic interference effects found in the dot-perspective task (Samson, Apperly, Braithwaite, Andrews, & Bodley Scott, 2010) are the product of domain-specific perspective-taking processes or of domain-general “submentalizing” processes (Heyes, 2014). Previous attempts to address this question have done so by implementing inanimate (...) controls, such as arrows, as stimuli. The rationale for this is that submentalizing processes that respond to directionality should be engaged by such stimuli, whereas domain-specific perspective-taking mechanisms, if they exist, should not. These previous attempts have been limited, however, by the implied intentionality of the stimuli they have used (e.g. arrows), which may have invited participants to imbue them with perspectival agency. Drawing inspiration from “novel entity” paradigms from infant gaze-following research, we designed a version of the dot-perspective task that allowed us to precisely control whether a central stimulus was viewed as animate or inanimate. Across four experiments, we found no evidence that automatic “perspective-taking” effects in the dot-perspective task are modulated by beliefs about the animacy of the central stimulus. Our results also suggest that these effects may be due to the task-switching elements of the dot-perspective paradigm, rather than automatic directional orienting. Together, these results indicate that neither the perspective-taking nor the standard submentalizing interpretations of the dot-perspective task are fully correct. (shrink)

Detroit Become Human (DBH) offers a stunningly visual gameplay experience that both tells a philosophical story and stimulates the moral reasoning process in players. The game features a futuristic world where highly intelligent androids are bought and sold as workers who take on menial labor tasks for humans. In this chapter, we explore three dimensions of moral reasoning: accounts of moral agency, ethical theories or frameworks, and accounts of moral patiency. We then explore how DBH addresses all of these philosophical (...) issues in its narrative and gameplay scenarios. Issues of moral agency are explored through some of the androids gaining consciousness and autonomy. Ethical theory is explored through various ethical dilemmas that emerge in the gameplay. Moral patiency is explored by questioning if the androids, conscious and unconscious, are worthy of moral concern and why. We then show how the gameplay structure offers a unique interactive opportunity for players to engage in the moral reasoning process. Additionally, through the questions it raises and scenarios it poses, DBH makes an implicit anti-speciesist argument regarding moral patiency. Additionally, it makes a secondary argument that suffering and struggle are necessary to develop the possibility of second-order desires and true freedom and agency. The interactive structure of the game, in which players’ choices have more weight than in many gameplay experiences, makes DBH a unique work of contemporary philosophical pop culture. (shrink)

Aron Gurwitsch (1900-73) was one of the most important figures in the phenomenological movement between the 1920s and the 1970s. Through his introduction of Gestalt theoretical concepts into phenomenology, he exerted a powerful influence on Maurice Merleau-Ponty and others. The contributions to this memorial volume, most written by friends and students of Gurwitsch, contain critical studies of the work of Aron Gurwitsch and attempts to extend his philosophical analyses to new problems and fields. Ranging from formal ontology through the philosophy (...) of the social sciences to the interpretation of Kant, the essays assembled here are both a tribute to and a continuation of the philosophical legacy of Aron Gurwitsch. The contributions will be of interest to advanced undergraduates and graduate students, and to specialists in a wide range of areas. (shrink)

David Earl Over is a leading cognitive scientist and, with his firm grounding in philosophical logic, he also exerts a powerful influence on the psychology of reasoning. He is responsible for not only a large body of empirical work and accompanying theory, but for advancing a major shift in thinking about reasoning, commonly known as the 'new paradigm' in the psychology of human reasoning. Over's signature mix of philosophical logic and experimental psychology has inspired generations of researchers, psychologists, and philosophers (...) alike over more than a quarter of a century. The chapters in this volume, written by a leading group of contributors including a number who helped shape the psychology of reasoning as we know it today, each take their starting point from the key themes of Over's ground-breaking work. The essays in this collection explore a wide range of central topics--such as rationality, bias, dual processes, and dual systems--as well as contemporary psychological and philosophical theories of conditionals. It concludes with an engaging new chapter, authored by David Over himself, which details and analyses the new paradigm psychology of reasoning. This book is therefore important reading for scholars, researchers, and advanced students in psychology, philosophy, and the cognitive sciences, including those who are not familiar with Over's thought already.

In the UK, many fundamentally important policy decisions that are likely to affect the relationship between citizens and care services are now made at the sublegislative level and without adequate ethical consideration and scrutiny. This is well exemplified in the proposed guidance on the disclosure of information on children. A recent consultation paper by the UK government on the subject proposes an approach that seeks a simple technical solution to a complex problem, emphasising control and surveillance. This reflects pressure to (...) be seen to act. The document fails with regard to ethical reflection appropriate to the complexity of the issue, an appreciation of complex relationships of trust, and a proper sense of the richness and complexity of the public interest. Such policies would, if implemented, fundamentally change the relationships between citizens and their carers, and among carers and the law and the state. This and similar proposals require far more ethical scrutiny and consideration of the public interest in the widest sense. (shrink)

Deep neural networks (DNNs) have had extraordinary successes in classifying photographic images of objects and are often described as the best models of biological vision. This conclusion is largely based on three sets of findings: (1) DNNs are more accurate than any other model in classifying images taken from various datasets, (2) DNNs do the best job in predicting the pattern of human errors in classifying objects taken from various behavioral datasets, and (3) DNNs do the best job in predicting (...) brain signals in response to images taken from various brain datasets (e.g., single cell responses or fMRI data). However, these behavioral and brain datasets do not test hypotheses regarding what features are contributing to good predictions and we show that the predictions may be mediated by DNNs that share little overlap with biological vision. More problematically, we show that DNNs account for almost no results from psychological research. This contradicts the common claim that DNNs are good, let alone the best, models of human object recognition. We argue that theorists interested in developing biologically plausible models of human vision need to direct their attention to explaining psychological findings. More generally, theorists need to build models that explain the results of experiments that manipulate independent variables designed to test hypotheses rather than compete on making the best predictions. We conclude by briefly summarizing various promising modeling approaches that focus on psychological data. (shrink)

An intermediate stage in Hrushovski’s construction of flat strongly minimal structures in a relational language L produces ω-stable structures of rank ω. We analyze the pregeometries given by forking on the regular type of rank ω in these structures. We show that varying L can affect the isomorphism type of the pregeometry, but not its finite subpregeometries. A sequel will compare these to the pregeometries of the strongly minimal structures.

The computations involved in statistical learning have long been debated. Here, we build on work suggesting that a basic memory process, chunking, may account for the processing of statistical regularities into larger units. Drawing on methods from the memory literature, we developed a novel paradigm to test statistical learning by leveraging a robust phenomenon observed in serial recall tasks: that short‐term memory is fundamentally shaped by long‐term distributional learning. In the statistically induced chunking recall (SICR) task, participants are exposed to (...) an artificial language, using a standard statistical learning exposure phase. Afterward, they recall strings of syllables that either follow the statistics of the artificial language or comprise the same syllables presented in a random order. We hypothesized that if individuals had chunked the artificial language into word‐like units, then the statistically structured items would be more accurately recalled relative to the random controls. Our results demonstrate that SICR effectively captures learning in both the auditory and visual modalities, with participants displaying significantly improved recall of the statistically structured items, and even recall specific trigram chunks from the input. SICR also exhibits greater test–retest reliability in the auditory modality and sensitivity to individual differences in both modalities than the standard two‐alternative forced‐choice task. These results thereby provide key empirical support to the chunking account of statistical learning and contribute a valuable new tool to the literature. (shrink)

Scholars and professional organizations in bioethics describe various approaches to “quality assessment” in clinical ethics. Although much of this work represents significant contributions to the literature, it is not clear that there is a robust and shared understanding of what constitutes “quality” in clinical ethics, what activities should be measured when tracking clinical ethics work, and what metrics should be used when measuring those activities. Further, even the most robust quality assessment efforts to date are idiosyncratic, in that they represent (...) evaluation of single activities or domains of clinical ethics activities, or a range of activities at a single hospital or healthcare system. Countering this trend, in this article we propose a framework for moving beyond our current ways of understanding clinical ethics quality, toward comprehensive quality assessment. We first describe a way to conceptualize quality assessment as a process of measuring disparate, isolated work activities; then, we describe quality assessment in terms of tracking interconnected work activities holistically, across different levels of assessment. We conclude by inviting future efforts in quality improvement to adopt a comprehensive approach to quality assessment into their improvement practices, and offer recommendations for how the field might move in this direction.
