Background The recent proliferation of health care report cards, especially in cardiac care, has occurred in the absence of an ethical framework to guide in their development and implementation. An ethical framework is a consistent and comprehensive theoretical foundation in ethics, and is formed by integrating ethical theories, relevant literature, and other critical information (such as the views of stakeholders). An ethical framework in the context of cardiac care provides guidance for developing cardiac report cards (CRCs) that are relevant and (...) legitimate to all stakeholders. The purpose of this study is to develop an ethical framework for CRCs. Methods Delphi technique – 13 panelists: 2 administrators, 2 cardiac nurses, 5 cardiac patients, 2 cardiologists, 1 member of the media, and 1 outcomes researcher. Panelists' views regarding the ethics of CRCs were analyzed and organized into themes. Results We have organized panelists' views into ten principles that emerged from the data: 1) improving quality of care, 2) informed understanding, 3) public accountability, 4) transparency, 5) equity, 6) access to information 7) quality of information, 8) multi-stakeholder collaboration, 9) legitimacy, and 10) evaluation and continuous quality improvement. Conclusion We have developed a framework to guide the development and dissemination of CRCs. This ethical framework can provide necessary guidance for those generating CRCs and may help them avoid a number of difficult issues associated with existing ones. (shrink)

ABSTRACT This paper reports on a multidisciplinary meeting held to discuss ethical issues in medical research in the developing world. Many studies, including clinical trials, are conducted in developing countries with a high burden of disease. Conditions under which this research is conducted vary because of differences in culture, public health, political, legal and social contexts specific to these countries. Research practices, including standards of care for participants, may vary as a result. It is therefore not surprising that ethical issues (...) emerge. This meeting sought to identify and discuss these issues from the perspectives of the many actors in such research, including community representatives, with a view to finding ethical and pragmatic solutions to these issues. Dialogue between these actors was also promoted, with a view to identifying the need to develop such dialogue in future. Drawing from the experiences of the speakers, the colloquium attempted to outline some answers to several key questions characterising the field today. Experiences related to epidemiologic research, vaccine trials, drug trials, diagnostic tests and to some fundamental ethical issues in health research. Speakers were from different countries, disciplines and professions. The meeting provided a forum for consultation and debate between different ethics actors. Both encouraging findings and challenges emerged. (shrink)

This paper explores the nature of virtue theory as applied to engineering practice. It links virtue to specific areas of practice such as the selection of ends, devotion to service, the formation of justified belief, the conduct of dialogue, the taking of actions, and exercises of the will. These areas are related to a culture of virtue in which an engineering society creates the conditions enabling acts of virtue and celebrates individuals and their acts which exemplify identified virtues. The result (...) is a basis for engineering ethics which draws attention to the impetus for an ethically sound life. (shrink)

Environmental actions require a willingness to act, which, in turn, is stimulated partially by the belief that an action will yield the desired consequences. In determining whether an actor was justified in exerting the will to act, therefore, it is essential to examine the nature of evidence offered by the actor in support of any beliefs about the environment. In this paper we explore the points in environmental risk analyses at which evidence is brought to bear in support of inferences (...) conceming environmental effects of regulatory actions. The intent is to provide a framework for discussing the manner in which evidence may provide a sufficient basis for ethically sound decisions for environmental actions. (shrink)

In this author-meets-critics dialogue, Sanjay Lal, author of, argues that Gandhian values of nonviolence raise aspirations of liberal democracy to a higher level. Since Gandhian values of nonviolence are closely associated with religious values, liberal democracy should make public commitments to religions on a non-sectarian basis, except for unreasonable religions. Critic Jeff Shawn Jose agrees that Gandhian values can strengthen liberal democracy. However, Jose finds a contradiction in Lal’s proposal that a liberal state should support reasonable religions only. A (...) more consistent Gandhian approach would focus on everyday interactions between citizens and groups rather than state-directed preferences. Critic Douglas Allen also welcomes Lal’s project that brings Gandhian philosophy into relation with liberal democratic theory; however, he argues that universalizing the Absolute Truth of genuine religion is more complicated than Lal acknowledges. D. Allen argues for a Gandhian approach of relative truths, which cannot be evaluated apart from contingency or context, and he offers autobiographical evidence in support of his critical suspicion of genuine religion. Critic Michael Allen argues that Lal’s metaphysical approach to public justification violates a central commitment of political liberalism not to take sides on any metaphysical basis. M. Allen argues that democratic socialism is closer to Gandhi’s approach than is liberalism. Lal responds to critics by arguing that Gandhi’s evaluation of unreasonable religions depends upon an assessment of violence, which is not as problematic as critics charge, either from a Gandhian perspective or a liberal one. Furthermore, by excluding unreasonable or violent religions from state promotion, Lal argues that he is not advocating state suppression. Finally, Lal argues that Gandhian or Kingian metaphysics are worthy of support by liberal, democratic states seeking to educate individuals regarding peaceful unity in diversity. (shrink)

It is widely agreed that reactive attitudes play a central role in our practices concerned with holding people responsible. However, it remains controversial which emotional attitudes count as reactive attitudes such that they are eligible for this central role. Specifically, though theorists near universally agree that guilt is a reactive attitude, they are much more hesitant on whether to also include shame. This paper presents novel arguments for the view that shame is a reactive attitude. The arguments also support the (...) view that shame is a reactive attitude in the sense that concerns moral accountability. The discussion thereby challenges both the view that shame is not a reactive attitude at all, suggested by philosophers such as R. Jay Wallace and Stephen Darwall, and the view that shame is a reactive attitude but does not concern moral accountability, recently defended by Andreas Carlsson and Douglas Portmore. (shrink)

William Albert Crawford-Frost was a Canadian born philosopher who developed a unique form of idealism that he called the Philosophy of Integration. This he presented in 1906 in a book by that title which he described in the subtitle as An Explanation of the Universe and of the Christian Religion. What I have taken the liberty of calling his Fusion Philosophy is the metaphysical theory outlined in this work as explained and developed further in his two other books, Old (...) Dogma in a New Light, and A New Theory of Evolution, as well as in a number of shorter pamphlets. I am using the term “fusion” rather than “integration” partly to avoid the social and political emphasis which the latter word has since acquired. However, I am not at all unhappy that my term “fusion” calls to mind our developing nuclear technology since, as will be seen, it is an implication of Crawford-Frost’s idealism that the development and application of nuclear fission, as opposed to fusion, is quite literally nothing less than the work of the Devil. This makes Crawford-Frost’s philosophy of some interest to us today, though I think that his unique form of idealism is, in many ways, interesting in itself. (shrink)

Vol. presents a method for critically evaluating relevance in arguments based on case studies & a new relevance theory incorporating techniques of argumentation theory, logic & artificiaI intelligence. For scholars/students in argumentation & rhetoric.

Media argumentation is a powerful force in our lives. From political speeches to television commercials to war propaganda, it can effectively mobilize political action, influence the public, and market products. This book presents a new and systematic way of thinking about the influence of mass media in our lives, showing the intersection of media sources with argumentation theory, informal logic, computational theory, and theories of persuasion. Using a variety of case studies that represent arguments that typically occur in the mass (...) media, Douglas Walton demonstrates how tools recently developed in argumentation theory can be usefully applied to the identification, analysis, and evaluation of media arguments.

A "slippery slope argument" is a type of argument in which a first step is taken and a series of inextricable consequences follow, ultimately leading to a disastrous outcome. Many textbooks on informal logic and critical thinking treat the slippery slope argument as a fallacy. Walton argues that used correctly in some cases, they can be a reasonable type of argument to shift a burden of proof in a critical discussion, while in other cases they are used incorrectly. Walton identifies (...) and analyzes four types of slippery slope argument. Walton presents guidelines that show how each type of slippery slope argument can be used correctly or incorrectly, using over fifty case studies of argumentation on controversial issues. These include abortion, medical research on human embryos, euthanasia, the decriminalization of marijuana, pornography, and censorship, and banning of American flag burning. (shrink)

Fundamentals of Critical Argumentation presents the basic tools for the identification, analysis, and evaluation of common arguments for beginners. The book teaches by using examples of arguments in dialogues, both in the text itself and in the exercises. Examples of controversial legal, political, and ethical arguments are analyzed. Illustrating the most common kinds of arguments, the book also explains how to evaluate each kind by critical questioning. Douglas Walton shows how arguments can be reasonable under the right dialogue conditions (...) by using critical questions to evaluate them. The book teaches by example, both in the text itself and in exercises, but it is based on methods that have been developed through the author's thirty years of research in argumentation studies.

This seminal work by political philosopher C.B. Macpherson was first published by the Clarendon Press in 1962, and remains of key importance to the study of liberal-democratic theory half-a-century later. In it, Macpherson argues that the chief difficulty of the notion of individualism that underpins classical liberalism lies in what he calls its "possessive quality" - "its conception of the individual as essentially the proprietor of his own person or capacities, owing nothing to society for them." Under such a conception, (...) the essence of humanity becomes freedom from dependence on the wills of others; society is little more than a system of economic relations; and political society becomes a means of safeguarding private property and the system of economic relations rooted in property. As the New Statesman declared: "It is rare for a book to change the intellectual landscape. It is even more unusual for this to happen when the subject is one that has been thoroughly investigated by generations of historians.... Until the appearance of Professor Macpherson's book, it seemed unlikely that anything radically new could be said about so well-worn a topic. The unexpected has happened, and the shock waves are still being absorbed." A new introduction by Frank Cunningham puts the work in a twenty-first-century context. (shrink)

Second edition of the introductory guidebook to the basic principles of constructing sound arguments and criticising bad ones. Non-technical in approach, it is based on 186 examples, which Douglas Walton, a leading authority in the field of informal logic, discusses and evaluates in clear, illustrative detail. Walton explains how errors, fallacies, and other key failures of argument occur. He shows how correct uses of argument are based on sound strategies for reasoned persuasion and critical responses. This edition takes into (...) account many developments in the field of argumentation study that have occurred since 1989, many created by the author. Drawing on these developments, Walton includes and analyzes 36 new topical examples and also brings in work on argumentation schemes. Ideally suited for use in courses in informal logic and introduction to philosophy, this book will also be valuable to students of pragmatics, rhetoric, and speech communication. (shrink)

Argumentation, which can be abstractly defined as the interaction of different arguments for and against some conclusion, is an important skill to learn for everyday life, law, science, politics and business. The best way to learn it is to try it out on real instances of arguments found in everyday conversational exchanges and legal argumentation. The introductory chapter of this book gives a clear general idea of what the methods of argumentation are and how they work as tools that can (...) be used to analyze arguments. Each subsequent chapter then applies these methods to a leading problem of argumentation. Today the field of computing has embraced argumentation as a paradigm for research in artificial intelligence and multi-agent systems. Another purpose of this book is to present and refine tools and techniques from computing as components of the methods that can be handily used by scholars in other fields. (shrink)

Recent work in artificial intelligence has increasingly turned to argumentation as a rich, interdisciplinary area of research that can provide new methods related to evidence and reasoning in the area of law. Douglas Walton provides an introduction to basic concepts, tools and methods in argumentation theory and artificial intelligence as applied to the analysis and evaluation of witness testimony. He shows how witness testimony is by its nature inherently fallible and sometimes subject to disastrous failures. At the same time (...) such testimony can provide evidence that is not only necessary but inherently reasonable for logically guiding legal experts to accept or reject a claim. Walton shows how to overcome the traditional disdain for witness testimony as a type of evidence shown by logical positivists, and the views of trial sceptics who doubt that trial rules deal with witness testimony in a way that yields a rational decision-making process.

Various theorists have endorsed the “communication argument”: communicative capacities are necessary for morally responsible agency because blame aims at a distinctive kind of moral communication. I contend that existing versions of the argument, including those defended by Gary Watson and Coleen Macnamara, face a pluralist challenge: they do not seem to sit well with the plausible view that blame has multiple aims. I then examine three possible rejoinders to the challenge, suggesting that a context-specific, function-based approach constitutes the most promising (...) modification of the communication argument.

In this volume, Douglas Yoder uses the tools of modern and postmodern philosophy and biblical criticism to elucidate the epistemology of the Tanakh, the collection of writings that comprise the Hebrew Bible. Despite the conceptual sophistication of the Tanakh, its epistemology has been overlooked in both religious and secular hermeneutics. The concept of revelation, the genre of apocalypse, and critiques of ideology and theory are all found within or derive from epistemic texts of the Tanakh. Yoder examines how philosophers (...) such as Spinoza, Hume, and Kant interacted with such matters. He also explores how the motifs of writing, reading, interpretation, image, and animals, topics that figure prominently in the work of Derrida, Foucault, and Nietzsche, appear also in the Tanakh. An understanding of Tanakh epistemology, he concludes, can lead to new appraisals of religious and secular life throughout the modern world. (shrink)

In classically based modal logic, there are three common conceptions of necessity, the universal conception, the equivalence relation conception, and the axiomatic conception. They provide distinct presentations of the modal logic S5, all of which coincide in the basic modal language. We explore these different conceptions in the context of the relevant logic R, demonstrating where they come apart. This reveals that there are many options for being an S5-ish extension of R. It further reveals a divide between the universal (...) conception of necessity on the one hand, and the axiomatic conception on the other: The latter is consistent with motivations for relevant logics while the former is not. For the committed relevant logician, necessity cannot be the truth in all possible worlds. (shrink)

The ability to reason and think in a logical manner forms the basis of learning for most mathematics, computer science, philosophy and logic students. Based on the author's teaching notes at the University of Maryland and aimed at a broad audience, this text covers the fundamental topics in classical logic in an extremely clear, thorough and accurate style that is accessible to all the above. Covering propositional logic, first-order logic, and second-order logic, as well as proof theory, computability theory, and (...) model theory, the text also contains numerous carefully graded exercises and is ideal for a first or refresher course.

One of the many claims about the value of local food is that local food exchanges generate trust between producers and consumers. To what degree is this actually the case and how does such trust develop? Drawing on interview and fieldwork data in one local food system in the Northeastern U.S., I show how local food participants build trust and reciprocity with one another in order to mitigate the challenges imposed by the conventional system. This trust and reciprocity builds primarily (...) through three mechanisms: reliable, positive relationships; demonstrations of good will toward one another; and a shared understanding of the value of locally-oriented food. Through these mechanisms, local food operators are able to build a healthy, stable local food system, able to better resist the pressures of the conventional system in which it must continually operate.

According to the response-dependence view of moral responsibility, a person is morally responsible just in case, and in virtue of the fact that, she is an appropriate target for reactive attitudes. This paper raises a new puzzle regarding response-dependence: there is a mismatch between the granularity of the reactive attitudes and of responsibility facts. Whereas the reactive attitudes are comparatively coarse-grained, responsibility facts can be quite fine-grained. This poses a challenge for response-dependence, which seeks to ground facts about responsibility in (...) facts about the reactive attitudes. Specifically, reactive attitudes are not enough for grounding facts about degrees of moral responsibility. The responsedependence view thus requires significant revisions or supplementations.

As local food activities expand and grow, an important question to answer is how various participants contribute to a local food system’s overall vitality and strength. This paper does so by focusing on the relationships between locally-oriented farm and retail actors and assessing what the configuration of these relationships tells us about the workings of the broader local food system. Such an analysis reveals two things. Empirically, it shows the important role food retailers play in the overall vibrancy of local (...) food exchanges: food retailers form crucial links holding the broader system together and significantly expanding consumer access to local foods. Further, different retailer types have distinct impacts on network configurations, each serving particular roles in the development and maintenance of local food systems. Methodologically, this paper shows the value of applying social network analysis techniques to the study of local food systems: such an approach yields insights that may not be as readily assessable from other strategies. In this paper, I overview common network analysis techniques and apply them to a case study of local food activities in New England, suggesting how such an approach might be applied to local food systems in other places.

There appears to be few, if any, limits on what sorts of logical connectives can be added to a given logic. One source of potential limitations is the motivating ideology associated with a logic. While extraneous to the logic, the motivating ideology is often important for the development of formal and philosophical work on that logic, as is the case with intuitionistic logic. One family of logics for which the philosophical ideology is important is the family of relevant logics. In (...) this paper, I explore the limits of what a relevant connective is, showing how some basic criteria motivated by the ideology of relevant logicians provide robust limits on potential connectives. These criteria provide some plausible necessary conditions on being a relevant connective. (shrink)

This paper addresses the question of how local can be defined in practice. It contributes to the growing literature on local food systems and particularly our understanding of what counts as local and the elements that influence those contours. While most of our conceptions of local food tend to rely on an articulation of either proximity traveled or relationship between entities, I argue that a more nuanced and complete understanding must take account of both of these aspects. I draw on (...) a dataset of locally oriented farm and food-related establishments in southern New England to identify how far local food travels in this region and how interconnected local food establishments are with one another and use these and other measures to tease out the tension between proximity and relationship as measures of local. I find that these two aspects not only are connected to each other in a complex dynamic, but also are bound up with other structural factors as well. (shrink)

On September 1, 2023, Texas made important revisions to it its decades‐old statute granting legal safe harbor immunity to physicians who withhold or withdraw life‐sustaining treatment over the objection of critically ill patients’ surrogate decision‐makers. However, lawmakers left untouched glaring flaws in a key safeguard for patients—the transfer option. The transfer option is ethically important because, when no hospital is willing to accept the patient in transfer, that fact is taken as strong evidence that the surrogates’ treatment requests fall outside (...) accepted medical practice. But there are serious shortcomings in how the transfer option is carried out in Texas and many other states, which undermines the ethical usefulness of the process. We identify these shortcomings and recommend revisions to state statutes and professional guidelines to overcome them. (shrink)

Wigmore thought that there was a science of proof underlying legal reasoning that could be displayed in any given case as a graphic sequence of argumentation from the evidence in the case leading to the ultimate probandum. Argumentation technology has now vindicated this approach by providing useful qualitative methods that can be applied to identifying, analyzing, and evaluating the pro and con arguments put forward by both sides in a trial. In this chapter, it is shown how to apply argumentation (...) schemes, such as argument from witness testimony, using argument diagrams applied to typical sequences of evidence-based legal reasoning in which there is a successive refinement of arguments displayed as the evidence comes into a case. It is shown how argument from applying rules to cases, teleological, argument from expert witness testimony, and abductive reasoning are centrally important for this purpose. (shrink)

An “insightful” and in-depth look at anti-science politics and its deadly results (Maria Konnikova, New York Times–bestselling author of The Biggest Bluff). Thomas Jefferson said, “Wherever the people are well informed, they can be trusted with their own government.” But what happens when they aren’t? From climate change to vaccinations, transportation to technology, health care to defense, we are in the midst of an unprecedented expansion of scientific progress—and a simultaneous expansion of danger. At the very time we need them (...) most, scientists and the very idea of objective knowledge are being bombarded by a vast, well-funded war on science, and the results are deadly. Whether it’s driven by identity politics, ideology, or industry, the result is an unprecedented erosion of thought in Western democracies as voters, policymakers, and justices actively ignore scientific evidence, leaving major policy decisions to be based more on the demands of the most strident voices. This compelling book investigates the historical, social, philosophical, political, and emotional reasons why evidence-based politics are in decline and authoritarian politics are once again on the rise on both left and right—and provides some compelling solutions to bring us to our collective senses, before it's too late. “If you care about attacks on climate science and the rise of authoritarianism, if you care about biased media coverage and shake-your-head political tomfoolery, this book is for you.”—The Guardian.

In relevant logics, necessary truths need not imply each other. In justification logic, necessary truths need not all be justified by the same reason. There is an affinity to these two approaches that suggests their pairing will provide good logics for tracking reasons in a fine-grained way. In this paper, I will show how to extend relevant logics with some of the basic operators of justification logic in order to track justifications or reasons. I will define and study three kinds (...) of frames for these logics. For the first kind of frame, I show soundness and highlight a difficulty in proving completeness. This motivates two alternative kinds of frames, with respect to which completeness results are obtained. Axioms to strengthen the justification logic portions of these logics are considered. I close by developing an analogy between the dot operator of justification logic and theory fusion in relevant logics. (shrink)

Functionalist accounts of blame have been rising in popularity. Proponents of the approach claim that, by defining blame in terms of its function or functions, their account has the advantage of being able to accommodate a wide range of attitudes and activities as blame; but their opponents question the extensional and explanatory adequacy of such accounts. This paper contributes to this burgeoning literature by presenting new challenges to the existing functionalist accounts. The fundamental problem, I shall argue, lies in the (...) fact that they all focus on using functions to define blame as a type of practice, but this strategy fails to pick out a unique moral-psychological type and does not offer a complete set of extension-determining criteria for the concept of blame. This amounts to a serious theoretical disadvantage. I consider various responses to the challenges throughout the paper, concluding that the best reply available to the functionalist theorist involves using functions to directly define blame tokens.

Growth in CSR-washing claims in recent decades has been dramatic in numerous academic and activist contexts. The discourse, however, has been fragmented, and still lacks an integrated framework of the conditions necessary for successful CSR-washing. Theorizing successful CSR-washing as the joint occurrence of five conditions, this paper undertakes a literature review of the empirical evidence for and against each condition. The literature review finds that many of the conditions are either highly contingent, rendering CSR-washing as a complex and fragile outcome. (...) This finding runs counter to the dominant perception in the general public, among activists, and among a vocal contingent of academics that successful CSR-washing is rampant. (shrink)

In _Real Natures and Familiar Objects_ Crawford Elder defends, with qualifications, the ontology of common sense. He argues that we exist -- that no gloss is necessary for the statement "human beings exist" to show that it is true of the world as it really is -- and that we are surrounded by many of the medium-sized objects in which common sense believes. He argues further that these familiar medium-sized objects not only exist, but have essential properties, which we (...) are often able to determine by observation. The starting point of his argument is that ontology should operate under empirical load -- that is, it should give special weight to the objects and properties that we treat as real in our best predictions and explanations of what happens in the world. Elder calls this presumption "mildly controversial" because it entails that arguments are needed for certain widely assumed positions such as "mereological universalism". Elder begins by defending realism about essentialness. He then defends this view of familiar objects against causal exclusion arguments and worries about vagueness. Finally, he argues that many of the objects in which common sense believes really exist, including artifacts and biological devices shaped by natural selection, and that we too exist, as products of natural selection.

Abstract According to Russellianism, the content of a Russellian thought, in which a person ascribes a monadic property to an object, can be represented as an ordered couple of the object and the property. A consequence of this is that it is not possible for a person to believe that a is F and not to believe b is F, when a=b. Many critics of Russellianism suppose that this is possible and thus that Russellianism is false. Several arguments for this (...) claim are criticized and it is argued that Russellians need not appeal to representational notions in order to defeat them. Contrary to popular opinion, the prospects for a pure Russellianism, a Russellianism without representations, are in fact very good. (shrink)

Most contemporary metaphysicians are sceptical about the reality of familiar objects such as dogs and trees, people and desks, cells and stars. They prefer an ontology of the spatially tiny or temporally tiny. Tiny microparticles 'dog-wise arranged' explain the appearance, they say, that there are dogs; microparticles obeying microphysics collectively cause anything that a baseball appears to cause; temporal stages collectively sustain the illusion of enduring objects that persist across changes. Crawford L. Elder argues that all such attempts to (...) 'explain away' familiar objects project downwards, onto the tiny entities, structures and features of familiar objects themselves. He contends that sceptical metaphysicians are thus employing shadows of familiar objects, while denying that the entities which cast those shadows really exist. He argues that the shadows are indeed really there, because their sources - familiar objects - are mind-independently real. (shrink)

This book provides a systematic analysis of many common argumentation schemes and a compendium of 96 schemes. The study of these schemes, or forms of argument that capture stereotypical patterns of human reasoning, is at the core of argumentation research. Surveying all aspects of argumentation schemes from the ground up, the book takes the reader from the elementary exposition in the first chapter to the latest state of the art in the research efforts to formalize and classify the schemes, outlined (...) in the last chapter. It provides a systematic and comprehensive account, with notation suitable for computational applications that increasingly make use of argumentation schemes. (shrink)

An important question for proponents of non-contractive approaches to paradox is why contraction fails. Zardini offers an answer, namely that paradoxical sentences exhibit a kind of instability. I elaborate this idea using revision theory, and I argue that while instability does motivate failures of contraction, it equally motivates failure of many principles that non-contractive theorists want to maintain.
