This article reports the results of research to develop a survey instrument and its use to validate an ethical business culture construct (CEBC Model). The reported three-stage quantitative study builds on our previous qualitative work, aimed at identifying dimensions of ethical business cultures. The research resulted in a parsimonious construct, covering five dimensions of ethical business cultures, and a ten-question instrument, measuring this construct. In this article, we report results of exploratory and confirmatory factor analyses and convergent construct validity testing, (...) discuss the potential applications of the construct and instrument in assessment and development of ethical business cultures, and provide recommendations for industry practitioners and for further research.

This study focuses on comparison of perceptions of ethical business cultures in large business organizations from four largest emerging economies, commonly referred to as the BRICs (Brazil, Russia, India, and China), and from the US. The data were collected from more than 13,000 managers and employees of business organizations in five countries. The study found significant differences among BRIC countries, with respondents from India and Brazil providing more favorable assessments of ethical cultures of their organizations than respondents from China and (...) Russia. Overall, highest mean scores were provided by respondents from India, the US, and Brazil. There were significant similarities in ratings between the US and Brazil. (shrink)

The purpose of this study was to identify general characteristics attributed to ethical business cultures by executives from a variety of industries. Our research identified five clusters of characteristics: Mission- and Values-Driven, Stakeholder Balance, Leadership Effectiveness, Process Integrity, and Long-term Perspective. We propose that these characteristics be used as a foundation of a comprehensive model that can be engaged to influence operational practices in creating and sustaining an ethical business culture.

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)

This is an encyclopedia entry on consequentializing. It explains what consequentializing is, what makes it possible, why someone might be motivated to consequentialize, and how to consequentialize a non-consequentialist theory.

In this, the sixth chapter of _Kantsequentialism: A Morality of Ends_, I argue that the duty of beneficence is best understood as a duty both (a) to adopt helping the needy as a serious, major, continually relevant, life-shaping end and (b) to refrain from acting in a way that would manifest one’s failure to do so. What’s more, I argue that Kantsequentialism offers us the best account of whether an act manifests a failure to have adopted helping the needy as (...) such a life-shaping end. I start by considering some alternative accounts of our duty of beneficence, examining where each goes wrong. I then conclude by showing how Kantsequentialism offers us the best approach to accommodating agent-centered options. (shrink)

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.

An unknown process is generating a sequence of symbols, drawn from an alphabet, A. Given an initial segment of the sequence, how can one predict the next symbol? Ray Solomonoff’s theory of inductive reasoning rests on the idea that a useful estimate of a sequence’s true probability of being outputted by the unknown process is provided by its algorithmic probability (its probability of being outputted by a species of probabilistic Turing machine). However algorithmic probability is a “semimeasure”: i.e., the sum, (...) over all x∈A, of the conditional algorithmic probabilities of the next symbol being x, may be less than 1. Prevailing wisdom has it that algorithmic probability must be normalized, to eradicate this semimeasure property, before it can yield acceptable probability estimates. This paper argues, to the contrary, that the semimeasure property contributes substantially to the power and scope of an algorithmic-probability-based theory of induction, and that normalization is unnecessary.

Avoiding partisan diatribe, Left Wing, Right Wing, People, and Power traces the historical development of the left wing and the right wing to reveal that the core of politics is the conflict over power. Despite specific differences of time and place, political actions are consistently efforts to preserve or change the structure and dynamics of power. With this insight, we can better understand political positions and actions. -/- Written in an accessible style, this book will inform readers regardless of where (...) they see themselves on the political spectrum. With clear but nuanced definitions of political ideologies and movements, the author shows how politics is people seeking to express and expand their power in the social space around them. Thus, the clash of the left and right wings is not about grand ideologies but instead is about power relations and the flow of power among people. (shrink)

This book provides a practical and accessible way of evaluating good and bad arguments used in everyday conversations by applying normative models of dialectical (interactive) argumentation, where two parties reason together in an orderly and cooperative way. Using case studies, the author analyzes correct and incorrect uses of argumentation on controversial issues that engage the reader's interest while illustrating points in a practical way. Walton gives clear explanations of the most common errors and tricky deceptions -- traditionally called "fallacies" -- (...) that can trip up an unwary arguer. (shrink)

Statutory interpretation involves the reconstruction of the meaning of a legal statement when it cannot be considered as accepted or granted. This phenomenon needs to be considered not only from the legal and linguistic perspective, but also from the argumentative one - which focuses on the strategies for defending a controversial or doubtful viewpoint. This book draws upon linguistics, legal theory, computing, and dialectics to present an argumentation-based approach to statutory interpretation. By translating and summarizing the existing legal interpretative canons (...) into eleven patterns of natural arguments - called argumentation schemes - the authors offer a system of argumentation strategies for developing, defending, assessing, and attacking an interpretation. Illustrated through major cases from both common and civil law, this methodology is summarized in diagrams and maps for application to computer sciences. These visuals help make the structures, strategies, and vulnerabilities of legal reasoning accessible to both legal professionals and laypeople. (shrink)

Scare Tactics, the first book on the subject, provides a theory of the structure of reasoning used in fear and threat appeal argumentation. Such arguments come under the heading of the argumentum ad baculum, the `argument to the stick/club', traditionally treated as a fallacy in the logic textbooks. The new dialectical theory is based on case studies of many interesting examples of the use of these arguments in advertising, public relations, politics, international negotiations, and everyday argumentation on all kinds of (...) subjects. Many of these arguments are amusing, once you see the clever tactic used; others are scary. Some of the arguments appear to be quite reasonable, while others are highly suspicious, or even outrageously fraudulent. In addition to the examples taken from logic textbooks, other cases treated come from a variety of sources, including political debates, legal arguments, and arguments from media sources, like magazine articles and television ads. The purpose of this book is to explain how such arguments work as devices of persuasion, and to develop a method for analyzing and evaluating their reasonable and fallacious uses in particular cases. The book shows how such arguments share a common structure, revealing several distinctive forms of argument nested within each other. Based on its account of this cognitive structure, the new dialectical theory presents methods for identifying, analyzing, and evaluating these arguments, as they are used in specific cases. The book is a scholarly contribution to argumentation theory. It is written in an accessible style, and uses many colorful and provocative examples of fear and threat appeal arguments that are suitable for classroom discussions. The matters treated will be of interest to professionals and students in law, critical thinking, advertising, speech communication, informal logic, cognitive science, rhetoric, and media studies.

We are happy to present to the reader the first book of our Applied Logic Series. Walton's book on the fallacies of ambiguity is firmly at the heart of practical reasoning, an important part of applied logic. There is an increasing interest in artifIcial intelligence, philosophy, psychol ogy, software engineering and linguistics, in the analysis and possible mechanisation of human practical reasoning. Continuing the ancient quest that began with Aristotle, computer scientists, logicians, philosophers and linguists are vigorously seeking to deepen (...) our understanding of human reasoning and argumentation. Significant communities of researchers are actively engaged in developing new approaches to logic and argumentation, which are better suited to the urgent needs of today's applications. The author of this book has, over many years, made significant contributions to the detailed analysis of practical reasoning case studies, thus providing solid foundations for new and more applicable formal logical systems. We welcome Doug Walton's new book to our series. (shrink)

Using tools like argument diagrams and profiles of dialogue, this paper studies a number of examples of everyday conversational argumentation where determination of relevance and irrelevance can be assisted by means of adopting a new dialectical approach. According to the new dialectical theory, dialogue types are normative frameworks with specific goals and rules that can be applied to conversational argumentation. In this paper is shown how such dialectical models of reasonable argumentation can be applied to a determination of whether an (...) argument in a specific case is relevant are not in these examples. The approach is based on a linguistic account of dialogue and text from congruity theory, and on the notion of a dialectical shift. Such a shift occurs where an argument starts out as fitting into one type of dialogue, but then it only continues to makes sense as a coherent argument if it is taken to be a part of a different type of dialogue.

This paper presents a formalization of informal logic using the Carneades Argumentation System, a formal, computational model of argument that consists of a formal model of argument graphs and audiences. Conflicts between pro and con arguments are resolved using proof standards, such as preponderance of the evidence. CAS also formalizes argumentation schemes. Schemes can be used to check whether a given argument instantiates the types of argument deemed normatively appropriate for the type of dialogue.

In response to the growing recognition of informal logic as a discipline in its own right, this collection of essays from leading contributors in the field provides the formative knowledge and historical context required to understand the development of a so far little studied subject area.

Argument invention is a method that can be used to help an arguer find arguments that could be used to prove a claim he needs to defend. The aim of this paper is to show how argumentation systems recently developed in artificial intelligence can be applied to the task of argument invention. One such system called Carneades is featured. Carneades can be used to analyze arguments, evaluate arguments, to make an argument diagram, and to construct arguments from a database. Using (...) some simple examples, the paper explains how Carneades works as a system of argument invention. (shrink)

Although studies have yielded a detailed taxonomy of types of slippery slope arguments, they have failed to identify a basic argumentation scheme that applies to all. Therefore, there is no way of telling whether a given argument is a slippery slope argument or not. This paper solves the problem by providing a basic argumentation scheme. The scheme is shown to fit a clear and easily comprehensible example of a slippery slope argument that strongly appears to be reasonable, something that has (...) also been lacking. (shrink)

This paper compares the features and methods of the two leading implemented systems that offer a tool for helping a user to find or invent arguments to support or attack a designated conclusion, the Carneades Argumentation System and the IBM Watson Debater tool. The central aim is to contribute to the understanding of scholars in informal logic, rhetoric and argumentation on how these two software systems can be useful for them. One contribution of the paper is to explain to these (...) potential users how the two tools are applicable to the task of inventing arguments by using some simple illustrative examples. Another is to redefine the structure of argument invention as a procedure. (shrink)

Even though tools for identifying and analyzing arguments are now in wide use in the field of argumentation studies, so far there is a paucity of resources for evaluating real arguments, aside from using deductive logic or Bayesian rules that apply to inductive arguments. In this paper it is shown that recent developments in artificial intelligence in the area of computational systems for modeling defeasible argumentation reveal a different approach that is currently making interesting progress. It is shown how these (...) systems provide the general outlines for a system of argument evaluation that can be applied to legal arguments as well as everyday conversational arguments to assist a user to evaluate an argument.

This paper considers how the terms ‘objection,’ ‘rebuttal,’ ‘attack,’ ‘refutation,’ ‘rebutting defeater’ and ‘undercutting defeater’ are used in writings on argumentation and artificial intelligence. The central focus is on the term ‘rebuttal.’ A provisional classification system is proposed that provides a normative structure within which the terms can be clarified, distinguished from each other, and more precisely defined.

In the 1950s–60s biochemists searched intensively for a series of high-energy molecules in the cell. Although we now believe that these molecules do not exist, biochemists claimed to have isolated or identified them on at least sixteen occasions. The episode parallels the familiar eighteenth-century case of phlogiston, in illustrating how error is not simply the loss of facts but, instead, must be actively constructed. In addition, the debates surrounding each case demonstrate how revolutionary-scale disagreement is sometimes resolved by differentiating or (...) partitioning empirical domains, rather than by replacement of one theory by another.

This book provides an argumentation model for means-end reasoning, a distinctive type of reasoning used for problem-solving gand decision-making. Means-end reasoning is modeled as goal-directed argumentation from an agent's goals and known circumstances, and from an action selected as a means, to a decision to carry out the action. Goal-based reasoning for argumentation provides an argumentation model for this kind of reasoning, showing how it is employed in settings of intelligent deliberation where agents try to collectively arrive at a conclusion (...) on what they should do to move forward in a set of circumstances. The book explains how this argumentation model can help build more realistic computational systems of deliberation and decision-making and shows how such systems can be applied to solve problems posed by goal-based reasoning in numerous fields, from social psychology and sociology, to law, political science, anthropology, cognitive science, artificial intelligence, multi-agent systems, and robotics." -- Back cover.

The Nature and Status of Critical Questions in Argumentation Schemes.

In this paper, a solution to the problem of analyzing burden of proof in argumentation is developed by building on the pioneering work of Erik C. W. Krabbe on metadialogues. Three classic cases of burden of proof disputes are analyzed, showing how metadialogue theory can solve the problems they pose. The solution is based on five dialectical requirements: (1) global burden of proof needs to be set at the confrontation stage of a dialogue, (2) there need to be special mechanisms (...) for resolving disputes about burden of proof at all four stages of the dialogue, (3) they are especially significant during the argumentation stage, where burden of proof often shifts back and forth at each move, (4) such local shifts need to be partly regulated by the global burden of proof already set, and (5) the connection between burden of proof and the speech act of making a presumption in a dialogue needs to be clarified.

This chapter proposes a dialectical approach to legal interpretation, consisting of three dimensions: a formalization of the canons of interpretation in terms of argumentation schemes; a dialectical classification of interpretive schemes; and a logical and computational model for comparing the arguments pro and contra an interpretation. The traditional interpretive maxims or canons used in both common and civil law are translated into defeasible patterns of arguments, which can be evaluated through sets of corresponding critical questions. These interpretive argumentation schemes are (...) classified in general categories and a distinction is drawn between schemes supporting and rebutting an interpretation. This framework allows conceiving statutory interpretation as a dialectical procedure consisting in weighing arguments pro and contra an interpretation. This procedure is formalized and represented computationally through tools from formal argumentation systems. (shrink)

This paper presents a formalization of informal logic using the Carneades Argumentation System, a formal, computational model of argument that consists of a formal model of argument graphs and audiences. Conflicts between pro and con arguments are resolved using proof standards, such as preponderance of the evidence. Carneades also formalizes argumentation schemes. Schemes can be used to check whether a given argument instantiates the types of argument deemed normatively appropriate for the type of dialogue.

This paper shows how the critical questions matching an argumentation scheme can be mod-eled in the Carneades argumentation system as three kinds of premises. Ordinary premises hold only if they are supported by sufficient arguments. Assumptions hold, by default, until they have been questioned. With exceptions the negation holds, by default, until the exception has been supported by sufficient arguments. By “sufficient arguments”, we mean arguments sufficient to satisfy the applicable proof standard.
