This book presents the state of the art in the fields of formal logic pioneered by Graham Priest. It includes advanced technical work on the model and proof theories of paraconsistent logic, in contributions from top scholars in the field. Graham Priest’s research has had a considerable influence on the field of philosophical logic, especially with respect to the themes of dialetheism—the thesis that there exist true but inconsistent sentences—and paraconsistency—an account of deduction in which contradictory premises do not entail (...) the truth of arbitrary sentences. Priest’s work has regularly challenged researchers to reappraise many assumptions about rationality, ontology, and truth. This book collects original research by some of the most esteemed scholars working in philosophical logic, whose contributions explore and appraise Priest’s work on logical approaches to problems in philosophy, linguistics, computation, and mathematics. They provide fresh analyses, critiques, and applications of Priest’s work and attest to its continued relevance and topicality. The book also includes Priest’s responses to the contributors, providing a further layer to the development of these themes. (shrink)

A wide family of many-valued logics—for instance, those based on the weak Kleene algebra—includes a non-classical truth-value that is ‘contaminating’ in the sense that whenever the value is assigned to a formula φ⁠, any complex formula in which φ appears is assigned that value as well. In such systems, the contaminating value enjoys a wide range of interpretations, suggesting scenarios in which more than one of these interpretations are called for. This calls for an evaluation of systems with multiple contaminating (...) values. In this paper, we consider the countably infinite family of multiple-conclusion consequence relations in which classical logic is enriched with one or more contaminating values whose behavior is determined by a linear ordering between them. We consider some motivations and applications for such systems and provide general characterizations for all consequence relations in this family. Finally, we provide sequent calculi for a pair of four-valued logics including two linearly ordered contaminating values before defining two-sided sequent calculi corresponding to each of the infinite family of many-valued logics studied in this paper.

In this article we revisit a number of disputes regarding significance logics---i.e., inferential frameworks capable of handling meaningless, although grammatical, sentences---that took place in a series of articles most of which appeared in the Australasian Journal of Philosophy between 1966 and 1978. These debates concern (i) the way in which logical consequence ought to be approached in the context of a significance logic, and (ii) the way in which the logical vocabulary has to be modified (either by restricting some notions, (...) or by adding some vocabulary) to keep as much of Classical Logic as possible. Our aim is to show that the divisions arising from these disputes can be dissolved in the context of a novel and intuitive proposal that we put forward. (shrink)

In neocolonial contexts of globalization, the epistemological terrain of radical diversity poses significant ethical challenges to transnational feminisms. In view of historical associations between knowledge and discourses of love which were conditioned by imperialist brands of humanism and benevolence under colonialism, this paper argues for a deconstructionist approach to conceptualizing love in relation to knowledge and for an ethics that severs the association with benevolence, instead making alterity the basis for its account.

Some photographs show determinate features of a scene because the photographed scene had those features. This dependency relation is, rightly, a consensus in philosophy of photography. I seek to refute many long-established theories of photography by arguing that they are incompatible with this commitment. In Section II, I classify accounts of photography as either single-stage or multi-stage. In Section III, I analyze the historical basis for single-stage accounts. In Section IV, I explain why the single-stage view led scientists to postulate (...) “latent” photographic images as a technical phenomenon in early chemical photography. In Section V, I discredit the notion of an invisible latent image in chemical photography and, in Section VI, extend this objection to the legacy of the latent image in digital photography. In Section VII, I appeal to the dependency relation to explain why the notion of a latent image makes the single-stage account untenable. Finally, I use the multi-stage account to advance debate about “new” versus “orthodox” theories of photography. (shrink)

According to Roger Scruton, it is not possible for photographs to be representational art. Most responses to Scruton’s scepticism are versions of the claim that Scruton disregards the extent to which intentionality features in photography; but these cannot force him to give up his notion of the ideal photograph. My approach is to argue that Scruton has misconstrued the role of causation in his discussion of photography. I claim that although Scruton insists that the ideal photograph is defined by its (...) ‘merely causal’ provenance, in fact he fails to take the causal provenance of photographs seriously enough. To replace Scruton’s notion of the ideal photograph, I offer a substantive account of the causal provenance of photographs, centred on the distinctive role of ‘the photographic event’. I conclude that, with a proper understanding of the photographic process, we have good reason to re-open the question of photography as a representational art. (shrink)

This article investigates some of the various ways in which theorists have used Machiavelli (and more specifically The Prince) in a business and management context and suggests that the two most common approaches, the use of metaphor and the use of analogy, are both flawed. Metaphor often relies on a reading of Machiavelli that cannot be sustained, whereas analogy takes Machiavelli too far out of historical context. This article discusses how business and management can more usefully incorporate Machiavelli’s ideas by (...) placing them within a tradition of discourse, along the lines of Lockyer’s historical method. We outline three potential discourses: those of humanism; of guides to leadership; and of power. In so doing the article suggests that historical texts (in particular Machiavelli) can prove useful to students and practitioners of business and management. (shrink)

What critical characteristics do firms have that determine the scale and scope of corporate social responsibility activities they undertake? This paper examines two disparate predictors of corporate social performance. First, using the lens of the resource-based view, we examine the role of alliance network centrality on corporate social performance. We find that centrality enhances corporate social performance. Second, we investigate how board composition affects corporate social performance. Specifically, drawing on stakeholder theory, we find that the percentage of female directors predicts (...) greater corporate social performance. In addition, we look at the influence of outside directors on this relationship. Our findings show that the presence of more outside directors positively moderates the relationship between female directors and corporate social performance. (shrink)

Drawing from our interdisciplinary qualitative study of LGBTI conservative Christians and their allies, we name an especially toxic form of shame—what we call sacramental shame—that affects the lives of LGBTI and other conservative Christians. Sacramental shame results from conservative Christianity's allegiance to the doctrine of gender complementarity, which elevates heteronormativity to the level of the sacred and renders those who violate it as not persons, but monsters. In dispensing shame as a sacrament, nonaffirming Christians require constant displays of shame as (...) proof that LGBTI church members love God and belong in the community. Part of what makes this shame so harmful is that parents and pastors often dispense it with sincere expressions of care and affection, compounding the sense that one's capacity to give and receive love is damaged. We foreground LGBTI Christian movements to overcome sacramental shame by cultivating nonhubristic pride, and conclude by discussing briefly their new understandings of love and justice that could have far‐reaching benefits.

Photography is valued as a medium for recording and visually reproducing features of the world. I seek to challenge the view that photography is fundamentally a recording process and that every photograph is a record—a view that I claim is based on a ‘single-stage’ misconception of the process. I propose an alternative, ‘multi-stage’ account in which I argue that causal registration of light is not equivalent to recording and reproducing an image. Intervention or non-intervention by photographers is more sophisticated than (...) the traditional view allows. Using the multi-stage account, I describe four models for producing photographic images and pictures. (shrink)

The placenta invades the adjacent uterus and controls the maternal immune system, like a cancer invades surrounding organs and suppresses the local immune response. Intriguingly, placental and cancer cells are globally hypomethylated and share an epigenetic phenomenon that is not well understood – they fail to silence repetitive DNA sequences that are silenced in healthy somatic cells. In the placenta, hypomethylation of retrotransposons has facilitated the evolution of new genes essential for placental function. In cancer, hypomethylation is thought to contribute (...) to activation of oncogenes, genomic instability, and retrotransposon unsilencing; the latter, we postulate, is possibly the most important consequence. Activation of placental retrotransposon-derived genes in cancer underpins our hypothesis that hypomethylation of these genes drives cancer cell invasion. This alludes to an interesting paradox, that while placental retrotransposon-derived genes are essential for promoting early hominid life, the same genes promote disease-susceptibility and death through cancer. Placental and cancer cells fail to silence retrotransposons that are normally silenced in healthy tissues. This has created new genes that are essential for placental function, yet they are also expressed in cancer. We hypothesize that active retrotransposons are a double-edged sword, contributing both adaptive and deleterious functions to biology. (shrink)

The author explores how the discursive practices of social texts relate to the subjectivities of readers. Employing Dorothy Smith's notion of femininity as textually mediated discourse, the author analyzes how teenage girls read the depictions of femininity in the glossy advertisements of fashion magazines. Through interviews with 48 girls aged 13 to 17 years, she explores both why and how young girls negotiate “what it means to be a woman.” Most young girls in her study draw on stereotypical meanings of (...) adult femininity. By giving these stereotypes truth status, these readers valorize not only patriarchal meanings of womanhood but also naturalize associations between femininity and the commodities through which this femininity is expressed as the everyday doing of gender. The author concludes by discussing implications of this study for both a feminist theory and a feminist politics of culture. (shrink)

Logics based on weak Kleene algebra (WKA) and related structures have been recently proposed as a tool for reasoning about flaws in computer programs. The key element of this proposal is the presence, in WKA and related structures, of a non-classical truth-value that is “contaminating” in the sense that whenever the value is assigned to a formula ϕ, any complex formula in which ϕ appears is assigned that value as well. Under such interpretations, the contaminating states represent occurrences of a (...) flaw. However, since different programs and machines can interact with (or be nested into) one another, we need to account for different kind of errors, and this calls for an evaluation of systems with multiple contaminating values. In this paper, we make steps toward these evaluation systems by considering two logics, HYB1 and HYB2, whose semantic interpretations account for two contaminating values beside classical values 0 and 1. In particular, we provide two main formal contributions. First, we give a characterization of their relations of (multiple-conclusion) logical consequence—that is, necessary and sufficient conditions for a set Δ of formulas to logically follow from a set Γ of formulas in HYB1 or HYB2 . Second, we provide sound and complete sequent calculi for the two logics. (shrink)

Bridging disciplines have much to teach us about how to combine analytical tools to tackle problems and questions that cross traditional disciplinary boundaries. This article uses examples from the older bridging disciplines of geography and anthropology in order to consider what the relatively young undertaking labeled “interdisciplinary studies” can learn from their long existence. It explains what is meant by the fallacy of nomothetic claim and considers the fruitful production of answers and solutions by viewing process (methodology) not domain (academic (...) turf), as the key to interdisciplinary success. Staking claim to interdisciplinarity is shown to be unproductive while finding the need for interdisciplinary approaches and following the mandates of that need in the pursuit of solutions to problems and questions strengthens both the disciplines and the development of interdisciplinary studies.

Concerns regarding corporate ethics have grown steadily throughout the past decade. In order to remain competitive, many organizational leaders are faced with the challenge of creating an ethical environment within their organization. A model is presented showing the process and elements necessary for the institutionalization of organizational ethics. The transformational leadership style lends itself well to the creation of an ethical environment and is suggested as a means to facilitate the institutionalization of corporate ethics. Finally, the benefits of using transformational (...) leadership are demonstrated through the components of a psychological contract, organizational commitment, and ethical culture to institutionalize organizational ethics.

The aim of this essay is to show that instances of valorising blackness have turned out to be harmful to African peoples. Whereas there have been several movements such as Black Power Movement, Black Consciousness Movement as well as individuals such as Steve Biko, Aime Cesaire, Leopold Sedar Senghor, William DuBois, Edward Blyden, Fela Anikulapo Kuti, it is the case that none of these minds made the conscious effort to interrogate the literal and symbolic use of black for Africans. Consequently, (...) this research limits its scope to Fela’s valorisation of blackness as enshrined in his blackism. Using the method of critical analysis, it argues that Fela’s “Blackism” takes the categorical and symbolic implications of blackness to an uncritical assimilation. The present study submits that until the ideological underpinning of the categorical and symbolic uses of blackness for Africans is engaged, all valorisation attempts will continue to yield meagre outputs. The first task is therefore to disclose the Eurocentric campaigns that mitigated the worth of the original or traditional people of Africa, south of the Sahara as well as the arrays of rejoinders which led to the valorisation of blackness. Afterward, Fela’s version of valorisation as encapsulated within the fold of his blackism will be disinterred. The rest of the paper shows not only that the valorisation agenda was a failed project but also that Fela’s “Blackism” is one of these failed projects. (shrink)

This paper examines two realisations of the television talk show in North America: The Oprah Winfrey Show and Dr. Phil, looking specifically at how they function within the sub-genre of ‘therapeutic talk show’ in keeping with Livingstone and Lunt’s (1994) classification of talk shows. Talk shows are defined by Ilie (2001) as “semi-institutional discourse” having features of a given setting (TV studio), topic- and goal-oriented talk, high degree of topic control, as well as restrictions on time and turn-taking. Theorists examining (...) this sub-genre of therapeutic talk show have argued that it provides a valuable means by which stories otherwise unrecognized have a forum, or that values of truth and honesty can be conveyed (Livingstone & Lunt 1994; Masciarotte 1991; Carbaugh 1988). However, theorists such as Abt and Seesholtz (1994) view therapeutic talk shows as potentially demeaning to guests who appear on them as well as a means by which suffering can be trivialized. Through an examination and analysis of requests for information, both direct and indirect, which are the principal features of all interviews, I look at how Oprah Winfrey and Dr. Phil problematize the narratives told by their guests. Both hosts rely heavily on one type of request, B-Event assertions functioning as indirect requests for information, to provoke specific response. My findings indicate that these talk shows do not in fact provide a forum for talk that would otherwise not be considered as suggested by Livingstone and Lunt (1994). Both Oprah Winfrey and Dr. Phil appropriate the stories provided by their guests; they also participate in their own overarching meta-narrative whereby as ‘heroes’ they solve their guests’ problems within a given time frame. Guests’ narrative responses share more with the speech act of confession than with free self-expression. The speech act of confession encouraged by these therapeutic talk shows serves in turn to reinforce conservatively-held values on the part of the at-home audience for whom such confession is also entertainment.

This article is concerned with the use of correspondence as research data. It focuses on the author's own experience of this method and considers the methodological implications of correspondence as a research method for research in general and feminist research in particular. We argue that at present this method is not often used, even though it provides rich data and is a potential powerful tool for feminist research.

German philosopher Martin Heidegger stirred educators when in 1951 he claimed teaching is more difficult than learning because teachers must ‘learn to let learn’. However in the main he left the aphorism unexplained as part of a brief four-paragraph, less than two-page set of observations concerning the relationship of teaching to learning; and concluded at the end of those observations that to become a teacher is an ‘exalted matter’. This paper investigates both of Heidegger's claims, interpreting letting learn in the (...) context of Heidegger's larger philosophical project, and suggesting why in light of that project to become a teacher is an exalted concern. The methodology guiding the inquiry is largely hermeneutic, the purpose of the essay to interpret teaching from a Heideggerian perspective: its nature and general method. (shrink)

In this article, we contribute to sociological literatures on morality, professional and institutional contexts, and morally stigmatized ‘dirty work’ by emphasizing and exploring how they mutually inform one another in lawyers’ work activities. Drawing on interview data with 58 practitioners in the commercial legal industry in Singapore, we analyze how they experience professional and institutional constraints on the expressions of morality in their work. Our findings illustrate how a dominant managerial and economic focus maintains and reproduces a constrained form of (...) morality, limited to instrumental, utilitarian and commercial ends, and subordinated to lucrative client and firm interests. We discuss our findings in terms of the need to research and reform professions in ways that support more rounded and unconstrained moral reflexivity and autonomy in how work is undertaken and valued. This in turn has implications for how organizations and professions might achieve alternative moral institutional orders, and for legal work to avoid the moral and social taints of dirty work.

In this article, we will consider how the regulation of populations is not just a feature of prisons, but of all institutions and organisations that control members though hierarchies, divisions and norms. While nurses and other allied health professionals are considered to be predominantly self‐regulatory, practice is guided by a code of conduct and codes of ethics that act as rules that serve to uphold the safety of the patient, whether they are a sick person in a hospital bed or (...) an inmate in a prison. The codes of conduct espouse a number of rules that to a certain extent govern the behaviour of individual and groups of practitioners through reciprocal rewards and punishments. Supervision is one method of monitoring the effectiveness of the codes of conduct and ethics while regulating both the minimum standard of individual practice and of training organisations. It is posited that one of the possible effects of clinical supervision is to make the person effectively self‐regulatory as, an autonomous practitioner. We take the view that professional autonomy is a highly problematic concept requiring closer examination. (shrink)

We are told by philosophers that photographs are a distinct category of image because the photographic process is mind-independent. Furthermore, that the experience of viewing a photograph has a special status, justified by a viewer’s knowledge that the photographic process is mind-independent. Versions of these ideas are central to discussions of photography in both the philosophy of art and epistemology and have far-reaching implications for science, forensics and documentary journalism. Mind-independence (sometimes ‘belief independence’) is a term employed to highlight what (...) is important in the idea that photographs can be produced naturally, mechanically, accidentally or automatically. Insofar as the process is physical, natural, mechanical or causal it can occur without human agency or intervention, entirely in the absence of intentional states. Presented innocuously, the idea is that although photographs are dependent on natural or mechanical processes, they can be produced independently of human agency – particularly human beliefs. Presented in a stronger form, the claim is that even if human agency is heavily involved in the production process, the definitive features that make the photograph a photograph and determine its salient properties are nonetheless independent of human minds. In epistemic debates, mind-independence is viewed as essential for explaining why photographs occupy a distinct category among images and justifying a variety of claims about their privileged epistemic and affective status in science, forensics, popular culture and journalism. But, in the philosophy of art, claims about mind-. (shrink)

This article explores how textual analysis can help us understand subjectivity as an empirical, rather than purely theoretical, phenomenon. The texts discussed here are advice columns in adolescent magazines; the analysis takes as its starting point girls’ accounts of magazine reading. Drawing on focus group discussions and interviews with 48 girls between the ages of 13 and 17 years, I explore how the accomplishment of ‘individuality’– as a culturally and historically-specific task of adolescence – is mediated by advice texts. Because (...) my analysis directs us to the existence of embodied subjects, I employ the notion of ‘Subject-ivity’. As a concept, ‘Subject-ivity’ reminds the analyst of the presence of an embodied, rather than theoretically constructed Self, brought into existence as a practical mode of consciousness. It thus provides a potential bridge between the sociological world of social subjects and highly theoretical work on subjectivity. (shrink)

Hannah Arendt famously argued that acts of violence are corrosive to a free and plural politics. However, the broader implications of her critique of violence are less well known. Reading her concept of violence comprehensively, with regard to (ostensibly non-political) labor and work as well as action, this article reveals its broader relevance for contemporary political thought: the political question of violence lies at the heart of our ecological crisis and is crucial for the social structure of labor domination. While (...) Arendtian politics is without normative guarantees, the conceptual distinction between instrumental violence and free politics is crucial, because it renders the political judgment of violence possible. In every realm of human activity, the refusal to acknowledge violence stunts our capacity to care for the world. (shrink)

We thank the commentators for their thoughtful engagement with our paper.1 In different ways, they make the same substantial point: our suggested interventions are not enough to solve the problems of organisational failure. On this we wholeheartedly agree. Organisational failure in healthcare is complex and multifaceted, it cannot be solved by one intervention in medical education. We did not intend to imply that our proposals alone would solve organisational failure, and this positioning misconstrues the aims of our paper. We had (...) more modest ambitions, we wanted to shift the analytical emphasis away from the individual and explore the implications raised by our analysis for our piece of the jigsaw—medical education. Having stepped away from such grand claims, the commentators make some valid points to which we would like to respond more specifically.

Discourses of interdisciplinary health‐care are becoming more centralised in the context of global healthcare practices, which are increasingly based on multisystem interventions. As with all dominant discourses that are narrated into being, many others have been silenced and decentralised in the process. While questions of the nature and constituents of interdisciplinary practices continue to be debated and rehearsed, this paper focuses on the discourse of interdisciplinary collaboration using psychiatry as an example, with the aim of highlighting competing and alternative discourses. (...) The fundamental premise of this paper is that collaborative relationships form the basis of interdisciplinary practices in psychiatry. Through a critical engagement and a deconstructive reading of the pretext, context and subtexts of interdisciplinarity, we interrogate the concept of interdisciplinary practice within psychiatry. We contend that an important part of understanding and further conceptualising the discourse is through fracturing it. This process is illustrated in the successive stages of our conceptual map of discourse development: establishing, maintaining and developing discourses. An understanding of interdisciplinary practice is not only critical for psychiatry, but also offers important insights into the performance of collaborative failures and indeed successes across nursing and allied health professions.

This chapter presents the text of a lecture on the legacies of surrealism in Latin America given at the 2009 British Academy Lecture Series. This text discusses the tensions between surrealist internationalism and local cultural nationalisms, the contested relationship between surrealism and Magic Realism, and the enduring surrealist fascination with Pre-Columbian art and architecture. It analyzes the works of Mexican artists Frida Kahlo and Gunther Gerzso and works of contemporary Brazilian artist Cildo Meireles. It contents that art from Latin America (...) has flourished in recent years without claiming surrealism as an exclusive source. (shrink)

Poovey has argued that the anesthetized “unresisting body” can offer no impediment to a doctor's interpretation of its conduct. In contrast, drawing on ethnographic data of anesthetic practice, this article suggests that the technological augmentation of the body required by present-day anesthesia enhances the ability of an unconscious body to convey its needs and shape the course of the anesthetic. In analyzing the expressions of anesthesia's cyborgs, the author draws on Haraway, Latour, and Suchman to reconsider the characteristics of agency (...) and how an unconscious body might “resist” or inform a doctor's interpretation. This attempt to explore the nature and distribution of agency within a collective is intended as a contribution to the debates surrounding medical dominance and those theorizing the role of technology in health care.
