This book brings together the basic documents needed for reaching an informed judgment on the central ethical question in the Pinto case: did Ford Motor Company act ethically in designing the Pinto fuel system and in deciding not to upgrade the integrity of that system until 1978? The five parts of this book cover the case, cost-benefit analysis, whistle blowing, product liability, and government regulations.

When software is written and then utilized in complex computer systems, problems often occur. Sometimes these problems cause a system to malfunction, and in some instances such malfunctions cause harm. Should any of the persons involved in creating the software be blamed and punished when a computer system failure leads to persons being harmed? In order to decide whether such blame and punishment are appropriate, we need to first consider if the people are “morally responsible”. Should any of the people (...) involved in creating the software be held morally responsible, as individuals, for the harm caused by a computer system failure?This article provides one view of moral responsibility and then discusses some barriers to holding people morally responsible. Next, it provides information about the Therac-25, a computer-controlled medical linear accelerator, and its computer systems failures that led to deaths and injuries. Finally it investigates whether two key people involved in the Therac-25 case could reasonably be considered to have some degree of moral responsibility for the deaths and injuries. The conclusions about whether or not these people were morally responsible necessarily rest upon a certain amount of speculation about what they knew and what they did. These limitations, however, should not cause us to conclude that discussions of moral responsibility are fruitless. In some cases, determinations of moral responsibility may be made and in others the investigation is still worthwhile, as the article demonstrates. (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)

The notion of burden of proof and its companion notion of presumption are central to argumentation studies. This book argues that we can learn a lot from how the courts have developed procedures over the years for allocating and reasoning with presumptions and burdens of proof, and from how artificial intelligence has built precise formal and computational systems to represent this kind of reasoning. The book provides a model of reasoning with burden of proof and presumption, based on analyses of (...) many clearly explained legal and non-legal examples. The model is shown to fit cases of everyday conversational argumentation as well as argumentation in legal cases. Burden of proof determines under what conditions an arguer is obliged to support a claim with an argument that backs it up and how strong that argument needs to be to prove the claim in question.

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.

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)

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)

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.

Aristotle's way of thinking has normally been understood as hostile to any liberal, pluralistic, or commercial society. In Liberal Nature, Rasmussen and Den Uyl set out to show that the Aristotelian approach to ethics supports the natural rights which form the most secure basis for liberal principles. The authors lay the foundations for their thesis by rebutting the most prominent arguments against the Aristotelian approach; they then offer a new interpretation for Aristotelian ethics as a natural-end ethics in which human (...) flourishing is the ultimate moral standard.

The aim of this paper is to display an alternative to the familiar decompositional approach in action theory, one that resists the demand for an explanation of action in non-agential terms, while not simply treating the notion of intentional agency as an unexplained primitive. On this Anscombean alternative, action is not a worldly event with certain psychological causes, but a distinctive form of material process, one that is not simply caused by an exercise of reason but is itself a productive (...) exercise of reason. I argue that to comprehend the proposed alternative requires an account of the temporality of events in general. An event does not simply have a position in time, but is itself temporally structured. With the inner temporality of events in view, the Anscombean conception of action as a specifically self-conscious form of temporal unity is made available for critical reflection. (shrink)

I owe you a dinner invitation, you owe ten years on your mortgage, and the government owes billions. We speak confidently about these cases of debt, but is that concept clear in its meaning? This book aims to clarify the concept of debt so we can find better answers to important moral and political questions. This book seeks to accomplish two things. The first is to clarify the concept of debt by examining how the word is used in language. The (...) second is to develop a general, principled account of how debts generate genuine obligations. This allows us to avoid settling each case by a bare appeal to moral intuitions, which is what we seem to currently do. It requires a close examination of many institutions, e.g. money, contract law, profit-driven finance, government fiscal operations, and central banking. To properly understand the moral and political nature of debt, we must understand how these institutions have worked, how they do work, and how they might be made to work. There have been many excellent anthropological and sociological studies of debt and its related institutions. Philosophy can contribute to the emerging discussion and help us to keep our language precise and to identify the implicit principles contained in our intuitions. (shrink)

In this first modern, critical assessment of the place of mathematics in Berkeley's philosophy and Berkeley's place in the history of mathematics, Douglas M. Jesseph provides a bold reinterpretation of Berkeley's work. Jesseph challenges the prevailing view that Berkeley's mathematical writings are peripheral to his philosophy and argues that mathematics is in fact central to his thought, developing out of his critique of abstraction. Jesseph's argument situates Berkeley's ideas within the larger historical and intellectual context of the Scientific Revolution. (...) Jesseph begins with Berkeley's radical opposition to the received view of mathematics in the philosophy of the late seventeenth and early eighteenth centuries, when mathematics was considered a "science of abstractions." Since this view seriously conflicted with Berkeley's critique of abstract ideas, Jesseph contends that he was forced to come up with a nonabstract philosophy of mathematics. Jesseph examines Berkeley's unique treatments of geometry and arithmetic and his famous critique of the calculus in The Analyst. By putting Berkeley's mathematical writings in the perspective of his larger philosophical project and examining their impact on eighteenth-century British mathematics, Jesseph makes a major contribution to philosophy and to the history and philosophy of science.

This study developed and tested a model of culture’s effect on budgeting systems, and hypothesized that system variables and reactions to them are influenced by culture-specific work-related and ethical values. Most organizational and behavioral views of budgeting fail to acknowledge the ethical components of the problem, and have largely ignored the role of culture in shaping organizational and individual values. Cross-cultural differences in reactions to system design variables, and in the behaviors motivated or mitigated by those variables, has implications for (...) the design and effectiveness of budgeting systems. The data largely support our research model, demonstrating the hypothesized national cultural differences in system design variables (e.g., participation, standards tightness, budget emphasis, etc. which we characterized as the opportunity and incentives to create budgetary slack), and the expected relationship between incentives (but not opportunity) to create slack and slack creation behavior. The data demonstrate hypothesized cultural differences in ethical ideology but show ethical ideology related to slack creation behavior only for U.S. managers. A discussion of the results and their implications is included. (shrink)

This paper explains the importance of classifying argumentation schemes, and outlines how schemes are being used in current research in artificial intelligence and computational linguistics on argument mining. It provides a survey of the literature on scheme classification. What are so far generally taken to represent a set of the most widely useful defeasible argumentation schemes are surveyed and explained systematically, including some that are difficult to classify. A new classification system covering these centrally important schemes is built.

Many high-income countries have skill-selective immigration policies, favoring prospective immigrants who are highly skilled. I investigate whether it is permissible for high-income countries to adopt such policies. Adopting what Joseph Carens calls a " realistic approach " to the ethics of immigration, I argue first that it is in principle permissible for high-income countries to take skill as a consideration in favor of selecting one prospective immigrant rather than another. I argue second that high-income countries must ensure that their skill-selective (...) immigration policies do not contribute to the non-fulfillment of their duty to aid residents of low-and middle-income countries.

SUMMARYThis paper discusses the scientific instruments made and used by the microscopist Antony van Leeuwenhoek. The immediate cause of our study was the discovery of an overlooked document from the Delft archive: an inventory of the possessions that were left in 1745 after the death of Leeuwenhoek's daughter Maria. This list sums up which tools and scientific instruments Leeuwenhoek possessed at the end of his life, including his famous microscopes. This information, combined with the results of earlier historical research, gives (...) us new insights about the way Leeuwenhoek began his lens grinding and how eventually he made his best lenses. It also teaches us more about Leeuwenhoek's work as a surveyor and a wine gauger.A further investigation of the 1747 sale of Leeuwenhoek's 531 single lens microscopes has not only led us to the identification of nearly all buyers, but also has provided us with some explanation about why only a dozen of this large number of microscopes has survived.

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)

The multiplicity of deubiquitinating enzymes (DUBs) encoded by vertebrate genomes is partly attributable to whole genome duplication events that occurred early in chordate evolution. By surveying the literature for the largest family of DUBs (the ubiquitin-specific proteases), extensive functional redundancy for duplicated genes has been confirmed as opposed to singletons. Dramatically conflicting results have been reported for loss of function studies conducted through RNA interference as opposed to inactivating mutations, but the contradictory findings can be reconciled by a recently proposed (...) compensatory mechanism involving nonsense-mediated RNA degradation. Duplicated genes are often inactivated to become pseudogenes, and it is proposed that such is the fate of the USP15 gene of zebrafish, a commonly used model system. As it is reviewed here, these observations have implications not only for the interpretation of model system phenotypes but also for therapeutic interventions designed to target DUBs. (shrink)

This article applies tools from argumentation theory to slippery slope arguments used in current ethical debates on genetic engineering. Among the tools used are argumentation schemes, value-based argumentation, critical questions, and burden of proof. It is argued that so-called drivers such as social acceptance and rapid technological development are also important factors that need to be taken into account alongside the argumentation scheme. It is shown that the slippery slope argument is basically a reasonable form of argument, but is often (...) flawed when used in ethical debates because of failures to meet the requirements of its scheme.

This paper addresses the problem posed by the current split between the two opposed hypotheses in the growing literature on the fallacy of begging the question the epistemic hypothesis, based on knowledge and belief, and the dialectical one, based on formal dialogue systems. In the first section, the nature of split is explained, and it is shown how each hypothesis has developed. To get the beginning reader up to speed in the literature, a number of key problematic examples are analyzed (...) illustrating how both approaches can be applied. Useful tools are brought to bear on them, including the automated argument diagramming system Araucaria, and profiles of dialogue used to represent circular argumentation in a dialogue tableau format. These tools are used to both to model circular reasoning and to provide the contextual evidence needed to properly determine whether the circular reasoning in a given case is better judged fallacious or not. A number of technical problems that have impeded the development of both hypotheses are studied. One central problem is the distinction between argument and explanation. It is concluded that the best way to move forward and solve these problems is to reformulate the two hypotheses in such a way that they might be able to co-exist. On this basis, a unified methodology is proposed that allows each hypothesis to move forward as a legitimate avenue for research using the same tools. (shrink)

Behavioral paternalism raises deep concerns that do not arise in traditional welfare economics. These concerns stem from behavioral paternalism’s acceptance of the defining axioms of neoclassical rationality for normative purposes, despite having rejected them as positive descriptions of reality. We argue that behavioral paternalists have indeed accepted neoclassical rationality axioms as a welfare standard; that economists historically adopted these axioms not for their normative plausibility, but for their usefulness in formal and theoretical modeling; that broadly rational individuals might fail to (...) satisfy the axioms for various reasons, making them unpersuasive as normative criteria; and that even if their violation did constitute irrationality, that would not justify paternalists’ choosing among inconsistent preferences to define an individual’s “true” preferences.

This book represents the first full-length study of the aesthetics of the appreciation of wine. It introduces and argues for the validity and significance of several new concepts: competency, project, and aesthetic practices. Using these concepts -- together with analyses borrowed from cognitive science, sensory science, Husserlian phenomenology and hermeneutics -- the case is made that wine can be a proper and indeed significant object of aesthetic attention. The implications of this are pursued in three ways: First, within the culture (...) of wine, with a sustained treatment of important concepts such as terroir; second, within philosophical aesthetics. The latter results in a position termed 'contextual aesthetics' that sees aesthetic acts as always situated within cultural practices, and given meaning thereby. The third implication is for the cultural and aesthetic value accorded to the various senses, and the kinds of underlying issues that might have led to, and might now lead away from, these values.

The Nature and Status of Critical Questions in Argumentation Schemes.

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.

I suggest that the social justice issues raised by Internet regulation can be exposed and examined by using a methodology adapted from that described by John Rawls in 'A Theory of Justice'. Rawls' theory uses the hypothetical scenario of people deliberating about the justice of social institutions from the 'original position' as a method of removing bias in decision-making about justice. The original position imposes a 'veil of ignorance' that hides the particular circumstances of individuals from them so that they (...) will not be influenced by self-interest. I adapt Rawls' methodology by introducing an abstract description of information technology to those deliberating about justice from within the original position. This abstract description focuses on computing devices that users can use to access information and information networks that information devices use to communicate. The abstractness of this description prevents the particular characteristics of the Internet and the computing devices in use from influencing the decisions about the just use and regulation of information technology and networks. From this abstract position, the principles of justice that the participants accept for the rest of society will also apply to the computing devices people use to communicate, and to Internet regulation.
