Root nodule morphogenesis involves the induction of mitotic activity in otherwise quiescent root cortical cells, giving rise to the nodule primordium. One gene expressed during nodule initiation, ENOD40, has been implicated in nodule growth and/or differentiation(1,2). Interestingly, although the nucleotide sequence of ENOD40 genes from soybean(3,4) and Medicago(1,2) are highly homologous, they are unlikely to encode a similar protein product. In fact, a remarkable feature of these genes is their apparent lack of protein coding potential. Thus, ENOD40 is a member (...) of the growing list of eukaryotic genes whose RNA product is implicated in control of cell growth and differentiation, the so called riboregulators(5). (shrink)

Outside of Italy, the country’s culture and its food appear to be essentially synonymous. And indeed, as The Italian Way makes clear, preparing, cooking, and eating food play a central role in the daily activities of Italians from all walks of life. In this beautifully illustrated book, Douglas Harper and Patrizia Faccioli present a fascinating and colorful look at the Italian table. The Italian Way focuses on two dozen families in the city of Bologna, elegantly weaving together Harper’s outsider (...) perspective with Faccioli’s intimate knowledge of the local customs. The authors interview and observe these families as they go shopping for ingredients, cook together, and argue over who has to wash the dishes. Throughout, the authors elucidate the guiding principle of the Italian table—a delicate balance between the structure of tradition and the joy of improvisation. With its bite-sized history of food in Italy, including the five-hundred-year-old story of the country’s cookbooks, and Harper’s mouth-watering photographs, The Italian Way is a rich repast—insightful, informative, and inviting.

Sexually transmitted infections (STIs) are socially constructed as more ‘dirty’ than other gynaecological conditions. This article analyses women’s accounts of interactions with clinicians, subsequent to a diagnosis of genital herpes simplex virus or human papilloma virus. Women conceptualised consultations as a ‘moral event,’ different from other consultations. This moral component is highlighted drawing on Foucault’s notion of ‘the confessional.’ Additionally, Douglas’ anthropological construction of ‘dirt’ is used to consider why these consultations are ‘confessional’ experiences. Email interviews were conducted with (...) 26 women diagnosed with a viral STI and 12 sexual health clinicians. Data were analysed thematically using a feminist, poststructuralist approach. Findings indicated that discourses of morality shape sexual health consultations. Five themes were identified in relation to the moral ‘work’ in clinical consultations about a viral STI diagnosis: the particular ‘dirtiness’ of viral STIs, clinicians as moral agents, the ‘non‐judgmental’ clinician, women juggling truth‐telling and risk and clinicians prescribing moral work. Clinicians support and educate women more effectively if they recognise subjective, moral aspects of sexual health consultations rather than assuming that effective clinical teaching is rational, scientific and non‐judgmental.

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.

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.

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)

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)

First published in 1959, this original study argues that the main characteristic of music is that it expresses and evokes emotion, and that all composers whose music has a tonal basis have used the same, or closely similar, melodic phrases, harmonies, and rhythms to affect the listener in the same ways. He supports this view with hundreds of musical examples, ranging from plainsong to Stravinsky, and contends that music is a language in the specific sense that we can identify idioms (...) and draw up a list of meanings. The book's final section analyzes two symphonies, Mozart's Fortieth and Vaughan Williams's Sixth, to explore the nature of musical inspiration and the process whereby the notes actually convey emotion from composer to listener.

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.

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.

For liberal contractarians, moral and political principles are justified if agreeable to persons as free and equals. But for critics of liberal contractarianism, this justification applies only to those capable of agreement. Understanding why contractarianism suffers from the problem of exclusion helps up understand the distinctive character of contractarianism and the importance of agreement in particular. I suggest contractarianism need not be objectionably exclusive. I first consider why agreement is important in contractarianism, and then introduce the main versions of contemporary (...) contractarianism and their different understandings of agreement. I discuss how agreement results in exclusion in each, and distinguish two kinds of response to the problem of exclusion: differential inclusion and permissive inclusion. Differential inclusion is unsuccessful because it offers those not fully capable of agreement unequal status. Permissive inclusion may either make the circumstances of agreement more open, or characterize the capacities required for inclusion more permissively. I advocate the latter as the most promising response to the problem of exclusion. I outline a more inclusive contractualism based on the capacity to share goals. (shrink)

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)

This book provides a critical overview of the entirety of Marcuse's work and discusses his enduring importance. Kellner had extensive interviews with Marcuse and provides hitherto unknown information about his road to Marxism, his relations with Heidegger and Existentialism, his involvement with the Frankfurt School, and his reasons for appropriating Freud in the 1950s. In addition Kellner provides a novel interpretation of the genesis and structure of Marcuse's theory of one-dimensional society, of the development of his political theory, and of (...) the role of aesthetics in his critical theory.

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)

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)

First published in 1984, Cultural Analysis is a systematic examination of the theories of culture contained in the writings of four contemporary social theorists: Peter L. Berger, Mary Douglas, Michel Foucault, and Jürgen Habermas. This study of their work clarifies their contributions to the analysis of culture and shows the converging assumptions that the authors believe are laying the foundation for a new approach to the study of culture. The focus is specifically on culture, a concept that remains subject (...) to ambiguities of treatment, and concentrates on questions concerning the definition and content of culture, its construction, its relations with social conditions, and the manner in which it may be changing. The books demonstrates how these writers have made strides towards defining culture as an objective element of social interaction which can be subjected to critical investigation. (shrink)

Although fallacies have been common since Aristotle, until recently little attention has been devoted to identifying and defining them. Furthermore, the concept of fallacy itself has lacked a sufficiently clear meaning to make it a useful tool for evaluating arguments. Douglas Walton takes a new analytical look at the concept of fallacy and presents an up-to-date analysis of its usefulness for argumentation studies. Walton uses case studies illustrating familiar arguments and tricky deceptions in everyday conversation where the charge of (...) fallaciousness is at issue. The numerous case studies show in concrete terms many practical aspects of how to use textual evidence to identify and analyze fallacies and to evaluate arguments as fallacious. Walton looks at how an argument is used in the context of conversation. He defines a fallacy as a conversational move, or sequence of moves, that is supposed to be an argument that contributes to the purpose of the conversation but in reality interferes with it. The view is a pragmatic one, based on the assumption that when people argue, they do so in a context of dialogue, a conventionalized normative framework that is goal-directed. Such a contextual framework is shown to be crucial in determining whether an argument has been used correctly. Walton also shows how examples of fallacies given in the logic textbooks characteristically turn out to be variants of reasonable, even if defeasible or questionable arguments, based on presumptive reasoning. This is the essence of the evaluation problem. A key thesis of the book, which must not be taken for granted as previous textbooks have so often done, is that you can spot a fallacy from how it was used in a context of dialogue. This is an innovative and even, as Walton notes, "a radical and controversial" theory of fallacy. (shrink)

A growing interest in and concern about the adequacy and fairness of modern peer-review practices in publication and funding are apparent across a wide range of scientific disciplines. Although questions about reliability, accountability, reviewer bias, and competence have been raised, there has been very little direct research on these variables.The present investigation was an attempt to study the peer-review process directly, in the natural setting of actual journal referee evaluations of submitted manuscripts. As test materials we selected 12 already published (...) research articles by investigators from prestigious and highly productive American psychology departments, one article from each of 12 highly regarded and widely read American psychology journals with high rejection rates (80%) and nonblind refereeing practices.With fictitious names and institutions substituted for the original ones (e.g., Tri-Valley Center for Human Potential), the altered manuscripts were formally resubmitted to the journals that had originally refereed and published them 18 to 32 months earlier. Of the sample of 38 editors and reviewers, only three (8%) detected the resubmissions. This result allowed nine of the 12 articles to continue through the review process to receive an actual evaluation: eight of the nine were rejected. Sixteen of the 18 referees (89%) recommended against publication and the editors concurred. The grounds for rejection were in many cases described as “serious methodological flaws.” A number of possible interpretations of these data are reviewed and evaluated. (shrink)

Commonsense Consequentialism is a book about morality, rationality, and the interconnections between the two. In it, Douglas W. Portmore defends a version of consequentialism that both comports with our commonsense moral intuitions and shares with other consequentialist theories the same compelling teleological conception of practical reasons. Broadly construed, consequentialism is the view that an act's deontic status is determined by how its outcome ranks relative to those of the available alternatives on some evaluative ranking. Portmore argues that outcomes should (...) be ranked, not according to their impersonal value, but according to how much reason the relevant agent has to desire that each outcome obtains and that, when outcomes are ranked in this way, we arrive at a version of consequentialism that can better account for our commonsense moral intuitions than even many forms of deontology can. What's more, Portmore argues that we should accept this version of consequentialism, because we should accept both that an agent can be morally required to do only what she has most reason to do and that what she has most reason to do is to perform the act that would produce the outcome that she has most reason to want to obtain.Although the primary aim of the book is to defend a particular moral theory, Portmore defends this theory as part of a coherent whole concerning our commonsense views about the nature and substance of both morality and rationality. Thus, it will be of interest not only to those working on consequentialism and other areas of normative ethics, but also to those working in metaethics. Beyond offering an account of morality, Portmore offers accounts of practical reasons, practical rationality, and the objective/subjective obligation distinction. (shrink)

Properties and objects are everywhere, but remain a philosophical mystery. Douglas Ehring argues that the idea of tropes--properties and relations understood as particulars--provides the best foundation for a metaphysical account of properties and objects. He develops and defends a new theory of trope nominalism.

What is truth? What role does truth play in the connections between language and the world? What is the relationship between truth and being? Douglas Edwards tackles these questions and develops a distinctive metaphysical worldview. He argues that in some domains language responds to the world, whereas in others language generates the world.

We hypothesised that belief in conspiracy theories would be predicted by the general tendency to attribute agency and intentionality where it is unlikely to exist. We further hypothesised that this tendency would explain the relationship between education level and belief in conspiracy theories, where lower levels of education have been found to be associated with higher conspiracy belief. In Study 1 participants were more likely to agree with a range of conspiracy theories if they also tended to attribute intentionality and (...) agency to inanimate objects. As predicted, this relationship accounted for the link between education level and belief in conspiracy theories. We replicated this finding in Study 2, whilst taking into account beliefs in paranormal phenomena. These results suggest that education may undermine the reasoning processes and assumptions that are reflected in conspiracy belief. (shrink)

The continuing power of racist ideology threatens liberal democracy, for racism is more than a personal bias or a social construction. It is an ideological framework that reduces human beings to an existence along a color-coded spectrum, with people designated as “white” at the top of the hierarchy and people designated as “black” at the bottom. One has to see this ideology clearly in order to choose a proper response and then act accordingly. First, the reality of “race” has been (...) exposed as unscientific and illusory, and as based not on biology or genetics, but on a legacy of empowerment for some and enslavement for others. Second, this racist ideology, part of our disenchanted, secular age, is exposed as a continuing form of enchantment in its manner of seeing the world, opening the possibility for a spiritual response. Third, dismantling this racist ideology requires a reimagining of “blackness” as a source of life and spirituality, as a way of countering and rewriting the dominant racist narrative. Fourth, a postsecular spiritualty, based on the work of Pope Francis—that emphasizes the importance of protecting our common human dignity, of caring for each other, and of “walking together”—can be engaged as a path for action in the battle against racism.

A new pragmatic approach, based on the latest developments in argumentation theory, analyzing appeal to expert opinion as a form of argument. Reliance on authority has always been a common recourse in argumentation, perhaps never more so than today in our highly technological society when knowledge has become so specialized—as manifested, for instance, in the frequent appearance of "expert witnesses" in courtrooms. When is an appeal to the opinion of an expert a reasonable type of argument to make, and when (...) does it become a fallacy? This book provides a method for the evaluation of these appeals in everyday argumentation. Specialized domains of knowledge such as science, medicine, law, and government policy have gradually taken over as the basis on which many of our rational decisions are made daily. Consequently, appeal to expert opinion in these areas has become a powerful type of argument. Challenging an argument based on expert scientific opinion, for example, has become as difficult as it once was to question religious authority. Walton stresses that even in cases where expert opinion is divided, the effect of it can still be so powerful that it overwhelms an individual's ability to make a decision based on personal deliberation of what is right or wrong in a given situation. The book identifies the requirements that make an appeal to expert opinion a reasonable or unreasonable argument. Walton's new pragmatic approach analyzes that appeal as a distinctive form of argument, with an accompanying set of appropriate critical questions matching the form. Throughout the book, a historical survey of the key developments in the evolution of the argument from authority, dating from the time of the ancients, is given, and new light is shed on current problems of "junk science" and battles between experts in legal argumentation.

This article presents a critical examination of the process of stakeholder dialogue in the Corporate Social Responsibility (CSR) field. It utilises data from a three-year research project into stakeholder dialogue processes to discuss three central themes: first, what is meant by the term ‘dialogue’, both from a theoretical perspective and from its practical application within CSR; second, the challenges of creating effective dialogue; and third, measuring and assessing the potential outcomes of dialogue. In providing a critical overview of these themes, (...) the article examines the nature of organisational learning through stakeholder engagement and dialogue. It questions the motives behind engagement in dialogue and highlights some of the potential challenges for organisational learning posed by opting for a stakeholder dialogue approach. It argues that organisations engaging in stakeholder dialogue must have a clear understanding of the implications of undertaking a dialogue process and have a long-term perspective regarding the outcomes and learning likely to emerge from it. While stakeholder dialogue may produce significant results, it is argued, many of these may be difficult to quantify on a short-term basis. (shrink)

_Arguments from Ignorance _explores the situations in which the argument from ignorance functions as a respectable form of reasoning and those in which it is indeed fallacious. Douglas Walton draws on everyday conversations on all kinds of practical matters in which the _argumentum ad ignorantiam _is used quite appropriately to infer conclusions. He also discusses the inappropriate use of this kind of argument, referring to various major case studies, including the Salem witchcraft trials, the McCarthy hearings, and the Alger (...) Hiss case. This book makes an original contribution in the areas of argumentation theory and informal logic, contending that, despite its traditional classification as a fallacy, the argument from ignorance is a genuine, very common, and legitimate type of argumentation with an identifiable structure. But the book is also interdisciplinary in scope, explaining many widely interesting and controversial subjects in artificial intelligence, medical education, philosophy of science, and philosophy of law in a clear way that makes it accessible to a broad range of readers.

This is an introductory guidebook to the basic principles of how to construct good arguments and how to criticeze bad ones. It is non-technical in its approach and is based on 150 key examples, each discussed and evaluated in clear, illustrative detail. Professor Walton, a leading authority in the field of informal logic, 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. Among the many subjects covered are: forms of valid argument, relevance, appeals to emotion, personal attack, uses and abuses of expert opinion, problems in deploying statistics, loading terms, equivocation, arguments from analogy, and techniques of posing, replying to, and criticizing questions. The book will be ideally suited to courses in informal logic and in the introduction to philosophy. It will also prove valuable to studetns of pragmatics, rhetoric, and speech communication.

This book examines three areas in which abductive reasoning is especially important: medicine, science, and law. The reader is introduced to abduction and shown how it has evolved historically into the framework of conventional wisdom in logic. Discussions draw upon recent techniques used in artificial intelligence, particularly in the areas of multi-agent systems and plan recognition, to develop a dialogue model of explanation. Cases of causal explanations in law are analyzed using abductive reasoning, and all the components are finally brought (...) together to build a new account of abductive reasoning. By clarifying the notion of abduction as a common and significant type of reasoning in everyday argumentation, _Abductive Reasoning_ will be useful to scholars and students in many fields, including argumentation, computing and artificial intelligence, psychology and cognitive science, law, philosophy, linguistics, and speech communication and rhetoric.

This book offers a new theory of begging the question as an informal fallacy, within a pragmatic framework of reasoned dialogue as a normative theory of critical argumentation. The fallacy of begging the question is analyzed as a systematic tactic to evade fulfillment of a legitimate burden of proof by the proponent of an argument. The technique uses a circular structure of argument to block the further progress of dialogue and, in particular, the capability of the respondent to ask legitimate (...) critical questions in reply to the argument. Walton analyzes the concept of burden of proof in argument, and provides chapters on the use of argument diagramming as a technique of argument reconstruction. This powerful method of argument analysis developed therein is then applied to more than 100 case studies of circular argumentation where the charge of begging the question is or has been thought to be an appropriate criticism. Throughout this work, Walton throws light on the relationship between the problem of circular reasoning and broader issues in the critical analysis of argumentation. Ground-breaking use is made of the pragmatic theory of argument as interactive dialogue. Rules for several kinds of dialogue framework provide standards of good reasoning to validate or to refute the criticism that a particular argument begs the question. This book is directed to students and professionals in the fields of speech communication, philosophy, linguistics, logic, dispute mediation, and education. (shrink)

ABSTRACT In this wide-ranging interview Professor Douglas V. Porpora discusses a number of issues. First, how he became a Critical Realist through his early work on the concept of structure. Second, drawing on his Reconstructing Sociology, his take on the current state of American sociology. This leads to discussion of the broader range of his work as part of Margaret Archer’s various Centre for Social Ontology projects, and on moral-macro reasoning and the concept of truth in political discourse.
