We show that the Lascar group $\operatorname {Gal}_L$ of a first-order theory T is naturally isomorphic to the fundamental group $\pi _1|)$ of the classifying space of the category of models of T and elementary embeddings. We use this identification to compute the Lascar groups of several example theories via homotopy-theoretic methods, and in fact completely characterize the homotopy type of $|\mathrm {Mod}|$ for these theories T. It turns out that in each of these cases, $|\operatorname {Mod}|$ is aspherical, i.e., (...) its higher homotopy groups vanish. This raises the question of which homotopy types are of the form $|\mathrm {Mod}|$ in general. As a preliminary step towards answering this question, we show that every homotopy type is of the form $|\mathcal {C}|$ where $\mathcal {C}$ is an Abstract Elementary Class with amalgamation for $\kappa $ -small objects, where $\kappa $ may be taken arbitrarily large. This result is improved in another paper. (shrink)

The paradoxes of self-reference are genuinely paradoxical. The liar paradox, Russell’s paradox and their cousins pose enormous difficulties to anyone who seeks to give a comprehensive theory of semantics, or of sets, or of any other domain which allows a modicum of self-reference and a modest number of logical principles. One approach to the paradoxes of self-reference takes these paradoxes as motivating a non-classical theory of logical consequence. Similar logical principles are used in each of the paradoxical inferences. If (...) one or other of these problematic inferences are rejected, we may arrive at a consistent (or at least, a coherent) theory. In this paper I will show that such approaches come at a serious cost. The general approach of using the paradoxes to restrict the class of allowable inferences places severe constraints on the domain of possible propositional logics, and on the kind of metatheory that is appropriate in the study of logic itself. Proof-theoretic and model-theoretic analyses of logical consequence make provide different ways for non-classical responses to the paradoxes to be defeated by revenge problems: the redefinition of logical connectives thought to be ruled out on logical grounds. Non-classical solutions are not the “easy way out” of the paradoxes. (shrink)

Consequence is at the heart of logic; an account of consequence, of what follows from what, offers a vital tool in the evaluation of arguments. Since philosophy itself proceeds by way of argument and inference, a clear view of what logical consequence amounts to is of central importance to the whole discipline. In this book JC Beall and Greg Restall present and defend what thay call logical pluralism, the view that there is more than one genuine deductive consequence relation, (...) a position which has profound implications for many linguists as well as for philosophers. We should not search for one true logic, since there are many. (shrink)

The allocation of scarce health care resources such as flu treatment or organs for transplant presents stark problems of distributive justice. Persad, Wertheimer, and Emanuel have recently proposed a novel system for such allocation. Their “complete lives system” incorporates several principles, including ones that prescribe saving the most lives, preserving the most life-years, and giving priority to persons between 15 and 40 years old. This paper argues that the system lacks adequate moral foundations. Persad and colleagues' defense of giving priority (...) to those between 15 and 40 leaves them open to the charge that they discriminate unfairly against children. Second, the paper contends that the complete lives system fails to provide meaningful practical guidance in central cases, since it contains no method for balancing its principles when they conflict. Finally, the paper proposes a new method for balancing principles of saving the most lives and maximizing life-years. (shrink)

Consequence is at the heart of logic, and an account of consequence offers a vital tool in the evaluation of arguments. This text presents what the authors term as 'logical pluralism' arguing that the notion of logical consequence doesn't pin down one deductive consequence relation; it allows for many of them.

During the academic year 1940-1941, several giants of analytic philosophy congregated at Harvard, holding regular private meetings, with Carnap, Tarski, and Quine. Carnap, Tarski, and Quine at Harvard allows the reader to act as a fly on the wall for their conversations. Carnap took detailed notes during his year at Harvard. This book includes both a German transcription of these shorthand notes and an English translation in the appendix section. Carnap’s notes cover a wide range of topics, but surprisingly, the (...) most prominent question is: If the number of physical items in the universe is finite, what form should scientific discourse take? This question is closely connected to an abiding philosophical problem: What is the relationship between the logico-mathematical realm and the material realm? Carnap, Tarski, and Quine’s attempts to answer this question involve issues central to philosophy today.This book focuses on three such issues: nominalism, the unity of science, and analyticity. In short, the book reconstructs the lines of argument represented in these Harvard discussions, discusses their historical significance (especially Quine’s break from Carnap), and relates them when possible to contemporary treatments of these issues.

A good argument is one whose conclusions follow from its premises; its conclusions are consequences of its premises. But in what sense do conclusions follow from premises? What is it for a conclusion to be a consequence of premises? Those questions, in many respects, are at the heart of logic (as a philosophical discipline). Consider the following argument: 1. If we charge high fees for university, only the rich will enroll. We charge high fees for university. Therefore, only the rich (...) will enroll. There are many different things one can say about this argument, but many agree that if we do not equivocate (if the terms mean the same thing in the premises and the conclusion) then the argument is valid, that is, the conclusion follows deductively from the premises. This does not mean that the conclusion is true. Perhaps the premises are not true. However, if the premises are true, then the conclusion is also true, as a matter of logic. This entry is about the relation between premises and conclusions in valid arguments. (shrink)

The Matthean parable of the labourers in the vineyard is open to multiple interpretations. For some, the parable may speak of God's unlimited grace and generosity; for others the parable may speak of God's unfairness. The present study is set within the context of an emerging interest in the concept of grace as a topic for empirical enquiry. The study draws on the theoretical framework provided by the notion of ordinary theology and employs the sensing, intuition, feeling and thinking (SIFT) (...) approach to biblical hermeneutics, which is rooted in Jungian psychological type theory. Data were drawn from two one-day workshops with Church of England Readers (lay ministers). On each occasion the participants were divided into three separate groups according to their preferences for thinking or feeling (the two judging functions proposed by psychological type theory) and within these groups they were invited to explore the messages about grace in Matthew 20:1-15 (Jesus' parable of the labourers in the vineyard). The rich data gathered from these workshops generated insights into contemporary theologies of grace and also confirmed the hypothesis that a biblical interpretation of grace is shaped by the reader's psychological type preference for thinking or feeling. While feeling types tended to empathise, thinking types pondered motives and unfairness. CONTRIBUTION: Situated within the reader perspective approach to biblical hermeneutics, the SIFT method is concerned with identifying the influence of the psychological type of the reader in shaping the interpretation of sacred text. Employing this method, the present study contributes to three fields of scholarship: to the field of homiletics and hermeneutics, to the field of ordinary theology and to the emerging field concerned with the concept of grace as a topic for empirical enquiry.

In this paper we offer a new argument for the existence of God. We contend that the laws of logic are metaphysically dependent on the existence of God, understood as a necessarily existent, personal, spiritual being; thus anyone who grants that there are laws of logic should also accept that there is a God. We argue that if our most natural intuitions about them are correct, and if they are to play the role in our intellectual activities that we take (...) them to play, then the laws of logic are best construed as necessarily existent thoughts -- more specifically, as divine thoughts about divine thoughts. We conclude by highlighting some implications for both theistic arguments and antitheistic arguments. (shrink)

We examine market reactions to publicly held multinational firms announcing their affiliation with the United Nations Global Compact (UNGC). The UNGC is a voluntary initiative to support four areas of United Nations viz. Human Rights, Labor, Environmental, and Anti-Corruption. Because firms must file annual Communication on Progress (COP) reports toward these initiatives, we argue this creates a differentiating transparency of interest to stakeholders. Using a sample of 175 global firms, we find support to the theory for joining the UNGC. Returns (...) differ markedly, however, between multinational firms headquartered in the United States (negative) and Europe (positive). We also find that failing to complete the annual COP generates a negative market reaction. (shrink)

The objective of this paper is to develop and describe a construct of the ethos of the corporate codes of ethics (i.e. an ECCE construct) across three countries, namely Australia, Canada and Sweden. The introduced construct is rather unique as it is based on a cross-cultural sample seldom seen in the literature. While the outcome of statistical analyses indicated a satisfactory factor solution and acceptable estimates of reliability measures, some research limitations have been stressed. They provide a foundation for further (...) research in the field and testing of the ECCE construct in other cultural and corporate settings. We believe that the ECCE construct makes a contribution to theory and practice in the field as it outlines a theoretical construct for the benefit of other researchers. It is also of managerial interest as it provides a grounded framework of areas to be considered in the implementation in organizations of corporate codes of ethics. (shrink)

Working within the sensing, intuition, feeling, thinking (SIFT) approach to biblical hermeneutics, the present study invited a hermeneutical community of 23 type-aware participants to explore the account of the Death of Lazarus as reported in John 11: 1–17 within type-alike groups differentiated according to the participants’ dominant function-orientation. Five groups were constituted differentiating: introverted sensing, introverted intuition, extraverted intuition, introverted and extraverted feeling and introverted and extraverted thinking. These five groups generated distinctive readings of the narrative that were characteristic of (...) the individual type preference. Contribution: The SIFT method, situated within the reader perspective approach to biblical hermeneutics, is concerned with attending to the influence exerted by the psychological type profile of the reader on interpreting the text. The present study goes beyond previous work by comparing the responses of five hermeneutical communities (each distinguished by a different dominant function-orientation) to the same passage of scripture.

I argue that a certain type of naturalist should not accept a prominent version of the no-miracles argument (NMA). First, scientists (usually) do not accept explanations whose explanans-statements neither generate novel predictions nor unify apparently disparate established claims. Second, scientific realism (as it appears in the NMA) is an explanans that makes no new predictions and fails to unify disparate established claims. Third, many proponents of the NMA explicitly adopt a naturalism that forbids philosophy of science from using any methods (...) not employed by science itself. Therefore, such naturalistic philosophers of science should not accept the version of scientific realism that appears in the NMA. (shrink)

We present several generalizations of the well-known Kunen inconsistency that there is no nontrivial elementary embedding from the set-theoretic universe V to itself. For example, there is no elementary embedding from the universe V to a set-forcing extension V[G], or conversely from V[G] to V, or more generally from one set-forcing ground model of the universe to another, or between any two models that are eventually stationary correct, or from V to HOD, or conversely from HOD to V, or indeed (...) from any definable class to V, among many other possibilities we consider, including generic embeddings, definable embeddings and results not requiring the axiom of choice. We have aimed in this article for a unified presentation that weaves together some previously known unpublished or folklore results, several due to Woodin and others, along with our new contributions.

Psalm 139 provides both great opportunities and huge challenges for the preacher. It is a Psalm crafted in four parts: part two is an imaginative and poetic affirmation of God’s omnipresence that engages the Jungian perceiving process; part four is a fierce and uncompromising diatribe against God’s enemies that engages the Jungian judging process. Interpretations of these two sections of the Psalm are explored among a sample of 30 Anglican deacons and priests serving as curates who were invited to work (...) in small hermeneutical communities, structured according to psychological type theory and designed to test the sensing, intuition, feeling and thinking (SIFT) approach to biblical hermeneutics and liturgical preaching. The findings from the hermeneutical communities demonstrated that the poetic power of part two was perceived quite differently by sensing types and by intuitive types. The judgement against God’s enemies in part four was evaluated quite differently by feeling types and by thinking types. The implications of these different readings of sacred text are discussed in relation both to hermeneutical theory and to homiletic practice. (shrink)

We are pluralists about logical consequence [1]. We hold that there is more than one sense in which arguments may be deductively valid, that these senses are equally good, and equally deserving of the name deductive validity. Our pluralism starts with our analysis of consequence. This analysis of consequence is not idiosyncratic. We agree with Richard Jeffrey, and with many other philosophers of logic about how logical consequence is to be defined. To quote Jeffrey.

It appears that in the 30 years that business ethics has been a discipline in its own right a model of business ethics has not been proffered. No one appears to have tried to explain the phenomenon known as 'business ethics' and the ways that we as a society interact with the concept, therefore, the authors have addressed this gap in the literature by proposing a model of business ethics that the authors hope will stimulate debate. The business ethics model (...) consists of three principal components that are interconnected by five sub-components. The introduced model makes a contribution to the creation of a conceptual framework for business ethics. A few tentative conclusions may be drawn from the introduced model of business ethics. The model aspires to be highly dynamic. The ultimate outcome is dependent upon the evolution of time and contexts. It is also dependent upon and provides reference to the behaviours and perceptions of people. The model proposes business ethics to be a continuous and an iterative process. There is no actual end of the process, but a constant reconnection to the initiation of successive process iterations of the business ethics model. The principals and sub-components of the model construct the dynamics of this continuous process. They provide guidance on what and how to explore our common efforts to understand the phenomenon known as business ethics. The model provides opportunities for further research in the field of business ethics. (shrink)

It is known that a number of inference principles can be used to trivialise the axioms of naïve comprehension - the axioms underlying the naïve theory of sets. In this paper we systematise and extend these known results, to provide a number of general classes of axioms responsible for trivialising naïve comprehension.

Many commentators on Alfred Tarski have, following Hartry Field, claimed that Tarski's truth-definition was motivated by physicalism—the doctrine that all facts, including semantic facts, must be reducible to physical facts. I claim, instead, that Tarski did not aim to reduce semantic facts to physical ones. Thus, Field's criticism that Tarski's truth-definition fails to fulfill physicalist ambitions does not reveal Tarski to be inconsistent, since Tarski's goal is not to vindicate physicalism. I argue that Tarski's only published remarks that speak approvingly (...) of physicalism were written in unusual circumstances: Tarski was likely attempting to appease an audience of physicalists that he viewed as hostile to his ideas. In later sections I develop positive accounts of: (1) Tarski's reduction of semantic concepts; (2) Tarski's motivation to develop formal semantics in the particular way he does; and (3) the role physicalism plays in Tarski's thought.

This study is situated within the newly emerging interest in the concept of grace as a legitimate topic for empirical enquiry, and draws on the theoretical framework provided by the SIFT approach to biblical hermeneutics, an approach rooted in reader-perspective hermeneutical theory and in Jungian psychological type theory. Data were draw from two one-day workshops with Anglican Readers (lay ministers). On each occasion the participants were invited to divide into three separate groups according to their preferences for sensing or intuition (...) (the two perceiving functions) and within these groups to explore the messages of grace in Matthew 6: 25–30 (Jesus’ invitation to look at the birds and to consider the lilies). The rich data gathered from these workshops generated insights into contemporary theologies of grace and also confirmed the hypothesis that biblical interpretation is shaped by the reader’s psychological type preference for sensing or for intuition.

Firms are under increasing pressure from external forces to do what is right and behave ethically. However, we have only a limited understanding of how ethical and responsible business practices impact the value of the firm, both in the short and the long term. In this study, we examine 196 firms that were recognized as the world's most ethical firms from 20 countries over a 14-year span. Results show that ethical behavior may have little effect on a firm's profitability in (...) the short term. However, it has a positive effect on a firm's market value, reflecting the market's positive assessment of its long-term performance. We also find that firms frequently listed among the world's most ethical companies tend to have higher market value than firms listed only once. (shrink)

This study invited curates and training incumbents attending a 3-day residential programme to function as a hermeneutical community engaging conversation between the Lucan post-resurrection narrative concerning the Road to Emmaus and the learning relationship in which they were engaged. Building on the SIFT approach to biblical hermeneutics the participants were invited to work in type-alike groups, structured first on the basis of the perceiving process and second on the basis of the judging process. This approach facilitated rich and varied insights (...) into the Emmaus Road narrative and into the theme of learning relationships. (shrink)

SummaryThis article offers a novel and comprehensive account of Walter Bagehot's political thought. It ties together an interpretation of Bagehot's liberal commitment to norms of discussion and deliberation, with an analysis of Bagehot's extensive arguments about the institutions of representative government. We show how Bagehot's opposition to American-style presidentialism, to parliamentary democracy, and to proportional representation were profoundly shaped by his conceptions of government by discussion, and the rule of public opinion. Bagehot's criticisms of English parliamentarianism, both of its pre-1832 (...) and post-1832 varieties were also motivated by those principles, as was his own proposal for parliamentary reform. By examining the whole range of Bagehot's writings on representative government and by connecting his institutional recommendations to his liberal principles, we are also able to better clarify Bagehot's position in Victorian political thought. The article concludes with a discussion of the debate leading up to the Second Reform Act, in which we elucidate Bagehot's disagreements with other prominent exponents of liberalism including John Stuart Mill, the “university liberals,” and Robert Lowe.

Refusing consent to organ donation remains unacceptably high, and improving consent rates from family or next-of-kin is an important step to procuring more organs for solid organ transplantation in countries where this approval is sought. We have thus far failed to translate fully our limited understanding of why families refuse permission into successful strategies targeting consent in the setting of deceased organ donation, primarily because our interventions fail to target underlying cognitive obstacles. Novel interventions to overcome these hurdles, incorporating an (...) understanding of cognitive psychology and behavioral change therapy, may be beneficial. One potential intervention is to use the concept of nudge theory, where decision-making is influenced by encouraging positive reinforcement and indirect suggestion. Purposefully nudging families to given consent for organ donation by understanding, and then overcoming, their inherent cognitive biases is novel but also controversial. This article explores the roles of relatives in decisions about organ donation, how nudge theory translates to organ donation and discusses the arguments for and against its application. (shrink)

This article explores how the type of consent given for organ donation should affect the judgement of a patient's overall benefit with regards to donation of their organs and the pre-mortem interventions required to facilitate this. The findings of a qualitative study of the views of 10 healthcare professionals, combined with a philosophical analysis inform the conclusion that how consent to organ donation is given is a reliable indicator only of the strength of evidence about views on donation and subsequent (...) willingness to undergo pre-mortem interventions. It is not an indicator of the strength of actual desire to donate. Clinical management of living patients prior to donation after circulatory death must therefore respect the values, wishes and beliefs of the potential donation after circulatory death donor. Our participants, however, suggested that the information currently provided is sufficient to authorise donation and that this consent, however provided, was sufficient to proceed with pre-mortem interventions. Respect for autonomy underpinned this ‘all or nothing’ approach. Although the legal requirements for donation authorisation and the protection of patients without capacity are clear, practice and policy regarding consent in donation after circulatory death may be based on donation following brainstem death where the patient is already dead when the family is approached. Custom and practice in donation after circulatory death may need to be revised to protect the interests of the dying potential donor. (shrink)

Rutherford and Lindell (2011) review an extensive literature on lateralization of emotion. As they note, an important issue surrounding this question is the nature of emotion, which bears on what, precisely, is lateralized. The present comments are intended to broaden the context of the review, by considering lateralization from the standpoint of a bivariate model of evaluative processes and a neuroevolutionary perspective.

The decision to divorce marks a turning point for every individual involved. It can be viewed as more than just a legal process. From a psychological perspective, it does not matter who initiated the divorce, since it always comes with emotional ramifications for all those involved. Statistically, there is a high rate of divorce in South Africa and there have been significant shifts in trends over time. While black South African men’s experience of divorce has been relatively neglected in the (...) research on divorce, it is important for understanding contemporary social arrangements and processes, and, in particular, for broadening the understanding of black South African men’s lives. How black South African men describe their experience and respond to marital dissolution may point to their positions in the gender-structured community as well as illuminate how they interpret the nature of social practice, marriage, divorce and their position in society. The aim of the research reported on in this paper was to explore black South African men’s experience of divorce. The theoretical framework underpinning this qualitative study was broadly that of Symbolic Interactionism, with Interpretative Phenomenological Analysis employed as both the research design and data analytic theory and process. The eight participants were volunteers who were recruited purposively. In keeping with IPA guidelines, data-collection proceeded by means of biographical questionnaires and semi-structured interviews. The emerging themes were grouped into three superordinate themes, namely, perceptions of divorce, social support, and experiencing of pain. Each superordinate theme had corresponding subordinate themes and experiential claims. Weed’s recommendations for the interpretative synthesis of interview data were applied. (shrink)

Many have tackled the question ‘What (if anything) is analytic philosophy?’ I will not attempt to answer this vexed question. Rather, I address a smaller, more manageable set of interrelated questions: first, when and how did people begin using the label ‘analytic philosophy’? Second, how did those who used this label understand it? Third, why did many philosophers we today classify as analytic initially resist being grouped together under the single category of ‘analytic philosophy’? Finally, for the first generation who (...) described themselves as analytic philosophers, what was their intended contrast class? Relatedly, when did ‘continental philosophy’ become the standard opposition? Some evidence I present justifies received answers to these questions; other evidence supports surprising and unorthodox answers to these questions. (shrink)
