This present study seeks to clarify the character and functions of the Neo-Babylonian empire in its relationship to subjugated populations, and in particular to the population of Judah.

Army Officers face increased moral pressure in modern warfare, where character judgement and ethical judgement are vital. This article reports the results of a study of 242 junior British Army officers using the Army Intermediate Concept Measure, comprising a series of professionally oriented moral dilemmas developed for the UK context. Results are suggestive of appropriate application of Army values to the dilemmas and of ethical reasoning aligning with Army excellence. The sample does slightly less well, however, for justification than for (...) action reasoning, and there are differences following initial training for infantry and artillery officers versus other branches of service. Dilemmas involving anti-torture methods and not covering up soldiers' failings generated best results compared to those requiring balance between compassion and mission, and negotiating personal relationships with military needs. Gender differences favouring women were less than those observed for other professional groups using similar measures. This research further develops a much-needed measure of ethical reasoning among junior Army officers, with potential for use among other ranks. This approach is advocated for other professional groups. (shrink)

In this volume, Stephen M. Gardiner and David A. Weisbach present arguments for and against the relevance of ethics to global climate policy. Gardiner argues that climate change is fundamentally an ethical issue, since it is an early instance of a distinctive challenge to ethical action, and ethical concerns are at the heart of many of the decisions that need to be made. Consequently, climate policy that ignores ethics is at risk of.

Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and (...) On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)

In the remainder of this article, we will disarm an important motivation for epistemic contextualism and interest-relative invariantism. We will accomplish this by presenting a stringent test of whether there is a stakes effect on ordinary knowledge ascription. Having shown that, even on a stringent way of testing, stakes fail to impact ordinary knowledge ascription, we will conclude that we should take another look at classical invariantism. Here is how we will proceed. Section 1 lays out some limitations of previous (...) research on stakes. Section 2 presents our study and concludes that there is little evidence for a substantial stakes effect. Section 3 responds to objections. The conclusion clears the way for classical invariantism.

Lockdown measures in response to the COVID-19 pandemic involve placing huge burdens on some members of society for the sake of benefiting other members of society. How should we decide when these policies are permissible? Many writers propose we should address this question using cost-benefit analysis, a broadly consequentialist approach. We argue for an alternative non-consequentialist approach, grounded in contractualist moral theorising. The first section sets up key issues in the ethics of lockdown, and sketches the apparent appeal of addressing (...) these problems in a CBA frame. The second section argues that CBA fundamentally distorts the normative landscape in two ways: first, in principle, it allows very many morally trivial preferences—say, for a coffee—might outweigh morally weighty life-and-death concerns; second, it is insensitive to the core moral distinction between victims and vectors of disease. The third section sketches our non-consequentialist alternative, grounded in Thomas Scanlon’s contractualist moral theory. On this account, the ethics of self-defence implies a strong default presumption in favour of a highly restrictive, universal lockdown policy: we then ask whether there are alternatives to such a policy which are justifiable to all affected parties, paying particular attention to the complaints of those most burdened by policy. In the fourth section, we defend our contractualist approach against the charge that it is impractical or counterintuitive, noting that actual CBAs face similar, or worse, challenges. (shrink)

For anyone concerned about students’ moral development, academic dishonesty presents a pervasive problem but also a promising possibility. The present paper describes the theoretical and empirical underpinnings of process-oriented, four-component model approach to promoting students’ “moral functioning” related to academic integrity, and the research project currently underway that is providing Web-based professional development to teachers for using the model in their high school classrooms. In doing so, we hope to develop a scalable approach that offers teachers an opportunity to be (...) the primary agents of change in transforming the problem of academic dishonesty into a possibility for positive youth development.

Speech and thought about what the law is commonly function in practical ways, to guide or assess behavior. These functions have often been seen as problematic for legal positivism in the tradition of H.L.A. Hart. One recent response is to advance an expressivist analysis of legal statements (Toh), which faces its own, familiar problems. This paper advances a rival, positivist-friendly account of legal statements which we call “quasi-expressivist”, explicitly modeled after Finlay’s metaethical theory of moral statements. This consists in a (...) descriptivist, “rule-relational” semantics combined with a pragmatic account of the expressive and practical functions of legal discourse. We argue that this approach is at least as well-equipped as expressivism to explain the motivational and prescriptive features of “internal” legal statements, as well as a fundamental kind of legal disagreement, while being better positioned to account for various “external” uses of the same language. We develop this theory in a Hartian framework, and in the final part of the paper argue (particularly against Toh’s expressivist interpretation) that Hart’s own views in The Concept of Law are best reconstructed along such quasi-expressivist lines.

Does the Ship of Theseus present a genuine puzzle about persistence due to conflicting intuitions based on “continuity of form” and “continuity of matter” pulling in opposite directions? Philosophers are divided. Some claim that it presents a genuine puzzle but disagree over whether there is a solution. Others claim that there is no puzzle at all since the case has an obvious solution. To assess these proposals, we conducted a cross-cultural study involving nearly 3,000 people across twenty-two countries, speaking eighteen (...) different languages. Our results speak against the proposal that there is no puzzle at all and against the proposal that there is a puzzle but one that has no solution. Our results suggest that there are two criteria—“continuity of form” and “continuity of matter”— that constitute our concept of persistence and these two criteria receive different weightings in settling matters concerning persistence.

In epistemology, fake-barn thought experiments are often taken to be intuitively clear cases in which a justified true belief does not qualify as knowledge. We report a study designed to determine whether non-philosophers share this intuition. The data suggest that while participants are less inclined to attribute knowledge in fake-barn cases than in unproblematic cases of knowledge, they nonetheless do attribute knowledge to protagonists in fake-barn cases. Moreover, the intuition that fake-barn cases do count as knowledge is negatively correlated with (...) age; older participants are less likely than younger participants to attribute knowledge in fake-barn cases. We also found that increasing the number of defeaters (fakes) does not decrease the inclination to attribute knowledge. (shrink)

Is behavioral integration (i.e., which occurs when a subjects assertion that p matches her non-verbal behavior) a necessary feature of belief in folk psychology? Our data from nearly 6,000 people across twenty-six samples, spanning twenty-two countries suggests that it is not. Given the surprising cross-cultural robustness of our findings, we suggest that the types of evidence for the ascription of a belief are, at least in some circumstances, lexicographically ordered: assertions are first taken into account, and when an agent sincerely (...) asserts that p, non-linguistic behavioral evidence is disregarded. In light of this, we take ourselves to have discovered a universal principle governing the ascription of beliefs in folk psychology. (shrink)

Disability and enhancement are often treated as opposing concepts. To become disabled in some respect is to move away from those who are enhanced in that same respect; to become enhanced is to move away from the corresponding state of disability. This chapter examines how best to understand the concepts of disability and enhancement in this symmetrical way. After considering various candidates, two types of accounts are identified as the most promising: welfarist accounts and typical-functioning accounts. The authors ultimately defend (...) a complex typical-functioning account as the best way to achieve a symmetrical understanding of disability and enhancement. (shrink)

Ludwig Wittgenstein and Martin Heidegger are arguably the two most influential philosophers of the twentieth century. Their work not only reshaped the philosophical landscape, but also left its mark on other disciplines, including political science, theology, anthropology, ecology, mathematics, cultural studies, literary theory, and architecture. Both sought to challenge the assumptions governing the traditions they inherited, to question the very terms in which philosophy’s problems had been posed, and to open up new avenues of thought for thinkers of all stripes. (...) And despite considerable differences in style and in the traditions they inherited, the similarities between Wittgenstein and Heidegger are striking. Comparative work of these thinkers has only increased in recent decades, but no collection has yet explored the various ways in which Wittgenstein and Heidegger can be drawn into dialogue. As such, these essays stage genuine dialogues, with aspects of Wittgenstein’s elucidations answering or problematizing aspects of Heidegger’s, and vice versa. The result is a broad-ranging collection of essays that provides a series of openings and provocations that will serve as a reference point for future work that draws on the writings of these two philosophers.

Like many, I find the idea of relying on patient preference predictors in life-or-death cases ethically troubling. As part of his stimulating discussion, Sharadin1 diagnoses such unease as a worry that using PPPs disrespects patients’ autonomy, by treating their most intimate and significant desires as if they were caused by their demographic traits. I agree entirely with Sharadin’s ‘debunking’ response to this concern: we can use statistical correlations to predict others’ preferences without thereby assuming any causal claim. However, I suspect (...) that, for at least some of us, our unease about PPPs stems from a different kind of ‘autonomy’ concern. In this commentary, then, I will explore this concern, and show how it relates to Sharadin’s work. Very many of our preferences are caused, ultimately, by facts which are outside our control, such as our demographic features. However, I suggest that we can still act autonomously on the basis of such preferences, when they are preferences which we endorse. Imagine, for example, that Jane has grown up in a church-growing environment, which has shaped many of her preferences, …. (shrink)

Connectionist models provide a promising alternative to the traditional computational approach that has for several decades dominated cognitive science and artificial intelligence, although the nature of connectionist models and their relation to symbol processing remains controversial. Connectionist models can be characterized by three general computational features: distinct layers of interconnected units, recursive rules for updating the strengths of the connections during learning, and “simple” homogeneous computing elements. Using just these three features one can construct surprisingly elegant and powerful models of (...) memory, perception, motor control, categorization, and reasoning. What makes the connectionist approach unique is not its variety of representational possibilities or its departure from explicit rule-based models, or even its preoccupation with the brain metaphor. Rather, it is that connectionist models can be used to explore systematically the complex interaction between learning and representation, as we try to demonstrate through the analysis of several large networks.

This paper explores some of the ethical issues around offering COVID-19 vaccines to children. My main conclusion is rather paradoxical: the younger we go, the stronger the grounds for justified parental hesitancy and, as such, the stronger the arguments for enforcing vaccination. I suggest that this is not thereductio ad absurdumit appears, but does point to difficult questions about the nature of parental authority in vaccination cases. The first section sketches the disagreement over vaccinating teenagers, arguing that the UK policy (...) was permissible. The second section outlines a problem for this policy, that it faces justified vaccine hesitancy. The third section discusses three strategies for responding to this problem, arguing that there may be no simple way of overcoming parents’ reasons to resist vaccinations. (shrink)

An exploratory pilot study with a small homogenous sample of Christian English speaking participants provided support for an alternative research hypothesis that a Christ consciousness contemplation with Heart Prayer of HeartMath techniques was significantly associated with increasing psychophysiological coherence, sense of coherence, spirituality and health perceptions. Participants described feelings of a peaceful place in oneness and connection with Christ. Integrative findings point towards Christ consciousness as an ultimately non-dual process of sensing vibrational resonance radiating from the human heart. Implications for (...) further research are discussed. (shrink)

The relationship between the social sciences and the cognitive sciences is underdeveloped and complicated, for reasons we will explain in this chapter, and the philosophical discussion of this relationship has the same properties. Many reasons for the lack of development relate to a traditional philosophical issue: explanation. The explanatory structure of cognitive science reasoning and argumentation is unusual and difcult to t into the traditional model of scientic explanation, though they do relate, in an odd way, to the traditional “reasons” (...) explanations discussed in the philosophy of social science, through the notion of “folk psychology.” The cognitive science explanations themselves, as they relate to traditional “social science” topics, involve additional problems. They depend on a strategy of reducing complexity by beginning with those aspects of mind that can be most readily simplied, such as perception and body movements. Therefore, traditional social science topics, such as social interaction, which cannot be readily simplied, are something of an afterthought. (shrink)

This integral investigation explored phenomenological and neurophysiologic, individual and collective dimensions of Christian Trinitarian meditation experiences in a volunteer, convenience sample of 10 practicing Christians, 6 men and 4 women, with a mean age of 48 years and an age range from 21 to 85 years. Participants meditated for a minimum period of 15 minutes, during which neurophysiologic data in the form of electroencephalographic (EEG), electromyographic (EMG), blood volume pulse (BVP) and respiratory activity were recorded. A phenomenological analysis indicated that (...) the meditation process generally involved a movement from body to mind to spirit as evident in reports of an increasingly relaxed, contented and focused state of consciousness characterised by Christian Trinitarian imagery, wonder, surrender, peace, bliss, openness and formlessness. The neuropsychological findings indicated significant increases, from baseline to meditation recordings, in the alpha and beta range, accompanied by increasing mean trends in the theta and gamma range, and decreasing mean trends in the delta range, EMG, BVP and respiration. Integrative findings indicated the practical theological value of small doses of Christian Trinity meditation to enhance spiritual life for those forms of waking, thinking, conscious behaviour needed in everyday world involvement and healing. Findings were discussed in relation to further integrative investigations and interventions with practical theological implications. (shrink)

The research was generally motivated by a dearth of studies on joy, and particularly inspired by a book of joy celebrating the inter-spiritual dialogue between the Dalai Lama and Desmond Tutu. Its aim was to investigate whether the direct contemplation of joy would be associated with improvements in psychophysiological coherence, spirituality and various positive emotions and feelings. Integrative quantitative and qualitative findings emerging from a small pilot study, including a convenience sample of six participants with a mean age of 42 (...) years and age range of 25-69 years, supported the research hypothesis. Significant quantitative increases in psychophysiological coherence, spirituality and positive feelings were coherently and consistently supported by participants' individual and collective experiences. Integrative discussion amplified the paradoxical theme of joy through suffering in human emotional and spiritual life. (shrink)

We propose as a UCGIS research priority the topic of “Ontological Foundations for Geographic Information.” Under this umbrella we unify several interrelated research subfields, each of which deals with different perspectives on geospatial ontologies and their roles in geographic information science. While each of these subfields could be addressed separately, we believe it is important to address ontological research in a unitary, systematic fashion, embracing conceptual issues concerning what would be required to establish an exhaustive ontology of the geospatial domain, (...) issues relating to the choice of appropriate methods for formalizing ontologies, and considerations regarding the design of ontology-driven information systems. This integrated approach is necessary, because there is a strong dependency between the methods used to specify an ontology, and the conceptual richness, robustness and tractability of the ontology itself. Likewise, information system implementations are needed as testbeds of the usefulness of every aspect of an exhaustive ontology of the geospatial domain. None of the current UCGIS research priorities provides such an integrative perspective, and therefore the topic of “Ontological Foundations for Geographic Information Science” is unique. (shrink)

Data science is characterized by engaging heterogeneous data to tackle real world questions and problems. But data science has no data of its own and must seek it within real world domains. We call this search for data “prospecting” and argue that the dynamics of prospecting are pervasive in, even characteristic of, data science. Prospecting aims to render the data, knowledge, expertise, and practices of worldly domains available and tractable to data science method and epistemology. Prospecting precedes data synthesis, analysis, (...) or visualization, and is constituted by the upstream work of discovering disordered or inaccessible data resources, thereafter to be ordered and rendered available for computation. Through this work, data science positions itself in the middle of all things—capable of engaging this, that, or any domain—and thus prospecting is a key driver of data science’s ongoing formation as a universal science.

Varieties of Ethical Reflection brings together new cultural and religious perspectives—drawn from non-Western, primarily Asian, philosophical sources—to globalize the contemporary discussion of theoretical and applied ethics.

This collection of essays contains revised versions of papers delivered at a conference entitled “Duty, Interest, and Practical Reason: Aristotle, Kant, and the Stoics” that was organized by Stephen Engstrom and Jennifer Whiting at the University of Pittsburgh in 1994. One of the main aims of the conference was to bring together scholars on Aristotle, the Stoics, and Kant to reevaluate the common view that Greek and Kantian ethics represent fundamentally opposed conceptions of ethical theory and the roles of (...) morality and happiness in practical reasoning. According to a common view, the ancients are eudaimonists; they derive or justify the virtues by showing how they contribute to the agent’s own eudaimonia or happiness. By contrast, Kant sharply criticizes eudaimonism for deriving or justifying morality in terms of happiness. This criticism applies to eudaimonism of all sorts, even Stoic eudaimonism, which is perhaps closer in some respects to Kant’s own views, and of which he is somewhat less critical than he is of other forms of eudaimonism. For Kant, moral duty and respect for the moral law must be grounded in reason itself and cannot be made to depend on any independent standard. These and related assumptions about ancient and Kantian ethics have helped structure much contemporary systematic work in ethical theory, as well as common conceptions of these ethical traditions. But this common view has been under reexamination lately; some of the most interesting work in the history of ethics in recent years has been in Greek and Kantian ethics, and much of it challenges one or another aspect of the received view of the ethical theory and moral psychology of Kant or the Greeks. However, with some exceptions, renewed interest and recent work in these two traditions has proceeded in parallel. The conference aimed to correct this, by bringing together some of the most distinguished scholars of ancient and modern ethics to compare and assess the role of moral duty and happiness in the two traditions. Most of the essays have such a comparative assessment as their main theme; but even those that focus more exclusively on one of the traditions contribute indirectly to this comparative assessment.

A COMPANION TO AESTHETICS This second edition of A Companion to Aesthetics examines questions that were among the earliest discussed by ancient philosophers, such as the nature of beauty and the relation between morality and art, while also addressing a host of new issues prompted by recent developments in the arts and in philosophy, including coverage of non-Western art traditions and of everyday and environmental aesthetics. The volume also canvases debates regarding the nature of representation, the relation between art and (...) truth, and the criteria for interpretation, which are among the most hotly discussed topics in contemporary philosophy. In this extensively revised and updated edition, 168 alphabetically arranged articles provide comprehensive treatment of the main topics and writers in aesthetics. Major additions include historical overviews from the prehistoric to the present and a section on the individual arts. A Companion to Aesthetics will serve students of philosophy, literary criticism, and cultural studies - as well as the educated general reader - both as a work of reference and, with its many substantial essays, as a guide to the best thinking about the arts from the ancient Greeks to the dawn of the twenty-first century.

Do our lives have meaning? Should we create more people? Is death bad? Should we commit suicide? Would it be better to be immortal? Should we be optimistic or pessimistic? Since Life, Death, and Meaning: Key Philosophical Readings on the Big Questions first appeared, David Benatar's distinctive anthology designed to introduce students to the key existential questions of philosophy has won a devoted following among users in a variety of upper-level and even introductory courses.

Demonstratives play a crucial role in the acquisition and use of language. Bringing together a team of leading scholars this detailed study, a first of its kind, explores meaning and use across fifteen typologically and geographically unrelated languages to find out what cross-linguistic comparisons and generalizations can be made, and how this might challenge current theory in linguistics, psychology, anthropology and philosophy. Using a shared experimental task, rounded out with studies of natural language use, specialists in each of the languages (...) undertook extensive fieldwork for this comparative study of semantics and usage. An introduction summarizes the shared patterns and divergences in meaning and use that emerge. (shrink)

“This is my major thesis. Mystery is inherent in both the nature of things and the nature of rationality. I will sustain this thesis by a review of some of the central issues of philosophy to elucidate their mysterious qualities. More important, however, I will develop in detail an explanation of mystery and trace some of its important ramifications.” “I will argue that an ordinal metaphysics, with its associated theory of query, provides an account of mystery that no other theory (...) can provide. “While the theory presented here is a theory of philosophical mystery, it has fundamental implications for all branches of knowledge, including the physical and social sciences. “In short, I speak against a simplistic view of the world and of experience based on a simplistic and narrow conception of understanding and rationality. Mystery calls not for veneration and awe, but for a full and complex activity of mind, broaching all established conditions in its pursuit of answers....Reason is fulfilled as completely in mysteries which persevere throughout our efforts to resolve them as in mysteries which are resolved and dissipated, passing into new questions to which we must find new answers, in an unterminating process of rational interrogation.” — From the Preface by Stephen David Ross.

A common complaint among those involved in teaching the educational foundations is the reluctance of many trainee teachers to engage in issues of educational theory. This is particularly apparent with those trainees who are more concerned with managing classrooms of children than grappling with what are often abstract and difficult ideas. This paper considers the current use of educational stories as a pedagogical strategy in teacher training, and a story that has been used in this way is presented. It is (...) argued that teachers of the educational foundations disciplines can, via stories, appeal to the opposing tensions and schemata in students’ own minds, and this engagement can be enhanced when students are confronted with broader educational debates, perspectives and proposals. Stories provide abstract concepts with a necessary tension, they suggest a way of entering the theoretical via the concrete and they show students the personal relevance of certain debates, which may have previously appeared remote and obscure. The end result is that students are challenged to make decisions about matters of fundamental importance such as the kinds of teachers they will be and about the ethical commitment they will make to teaching.

The rediscovery in the fifteenth century of Lucretius's De rerum natura was a challenge to received ideas. The poem offered a vision of the creation of the universe, the origins and goals of human life, and the formation of the state, all without reference to divine intervention. It has been hailed in Stephen Greenblatt's best-selling book, The Swerve, as the poem that invented modernity. But how modern did early modern readers want to become? From Lucretius' contemporary audience to the (...) European Enlightenment, this collection of essays offers a series of case studies which demonstrates the sophisticated ways in which some readers might relate the poem to received ideas, assimilating Lucretius to theories of natural law and even natural theology, while others were at once attracted to Lucretius's subversiveness and driven to dissociate themselves from him.

When a human being comes into existence is crucial in bioethics. Conceptionism is the view that a human being comes into existence at conception. The twinning argument is an influential objection to this view. All versions of the twinning argument rely on a metaphysics of material objects, namely, endurantism. Given this, a strategy for defending conceptionism against the twinning argument is to deny endurantism and adopt an alternative metaphysics of material objects. A version of this strategy which has been debated (...) in this journal is to adopt perdurantism, or the ‘multiple occupancy view’, on which monozygotic twins share the zygote region as a temporal part. We present a novel version of this strategy: conceptionists can evade the twinning argument by adopting an exdurantist metaphysics of material objects. We suggest reasons for thinking that this is a plausible and, indeed, preferable way for conceptionists to avoid the twinning argument. (shrink)
