We employ the Social Signaling Model and life history of a Western Dani big-man, Tibenuk, to analyze a neglected curiosity in the career of the big-man type. The big-man is renowned as an economic entrepreneur, the master of material displays. In New Guinea, however, big-men had invariably first gained fame and some influence as eminent warriors. The SSM accounts for this two-part career path by proposing that small-scale social organization rests on honest, competitive signaling of individual and collective fighting strength, (...) with leaders being those who excel in these contests. The performances for which big-men are already known, conspicuous ceremonial displays, broadcast this strength indirectly. Explicitly conceptualized as symbolic fighting, they constituted indexical proxies for their sponsors’ individual and collective willingness and ability to fight. Success on the battlefield, though, signaled fighting strength more directly. Men therefore had to demonstrate strength on both the battlefield and the ceremonial ground if they were to become big-men. This was Tibenuk’s achievement. When he was young and at his physical peak, he demonstrated outstanding capability in war. War is a young man’s game, however, and as his physical capacities waned, he shifted to politics, an older man’s game, honing his political talents and developing extensive political networks that allowed him to sponsor massive pig feasts, the principal form of conspicuous ceremonial display. Tibenuk’s career also reveals synergies between warrior and political talents that hitherto have been overlooked in big-man analysis. (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.

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.

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)

An important question about eye-movement behavior is when the decision is made to terminate a fixation and program the following saccade. Different approaches have found converging evidence in favor of a mixed-control account, in which there is some overlap between processing information at fixation and planning the following saccade. We examined one interesting instance of mixed control in visual search: lag-2 revisits, during which observers fixate a stimulus, move to a different stimulus, and then revisit the first stimulus on the (...) next fixation. Results show that the probability of lag-2 revisits occurring increased with the number of target-similar stimuli, and revisits were preceded by a brief fixation on the intervening distractor stimulus. We developed the Efficient Visual Sampling computational model to simulate our findings and to provide insight into mixed control of fixations and the perceptual, cognitive, and motor processes that produce lag-2 revisits.

In this paper, Bronwyn Hayward, a New Zealander, explores Iris Marion Young's argument for decentered deliberation in the context of climate change debate in the South Pacific. Young's criticisms of a centered approach to local planning are examined. Hayward supports Young's argument for decentered deliberation and her concept of ‘linkage’ as a criterion of good decentered democracy. Local forums are identified as essential sites of struggle against injustice. Decentered democracy is strengthened when multiple linkages connect heal forums across (...) time and space. (shrink)

This book provides a distinctive and rich conception of methodology within international studies. From a rereading of the works of leading Western thinkers about international studies, Hayward Alker rediscovers a 'neo-Classical' conception of international relations which is both humanistic and scientific. He draws on the work of classical authors such as Aristotle and Thucydides; modern writers like Machiavelli, Vico, Marx, Weber, Deutsch and Bull; and post-modern writers like Havel, Connolly and Toulmin. The central challenge addressed is how to integrate (...) 'positivist' or 'falsificationist' research styles within humanistic or interpretive ones. The author argues that appropriate, philosophically informed reformulations of conventional statistical and game-theoretic analyses are possible, and describes a number of humanistic methodologies for international relations, including argumentation analysis, narrative modeling, computational models of political understanding and reconstructive analysis.

Recent democratic theorists have drawn on the work of the late Pierre Bourdieu to make the case that patterned inequalities in the social capacity to engage in deliberation can undermine deliberative theory’s democratic promise. They have proposed a range of deliberative democratic responses to the problem of cultural inequality, from enabling the marginalised to adopt the communicative dispositions of the dominant, to broadening the standards that define legitimate deliberation, to strengthening deliberative counter‐publics. The author interprets Bourdieu’s theory of the linguistic (...) habitus to prompt an even more radical critique of deliberative democracy than these theorists acknowledge, one to which the proposed solutions fail adequately to respond. Her argument suggests that empirical work on deliberative democracy should expand to address specifically the problems of cultural inequality that Bourdieu’s work highlights. (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)

A major problem that skeptical critics have identified with the project of environmental ethics as it is often conceived is that it involves the search for a criterion of moral considerability, and some claim that this search has not only been unsuccessful, but it is in principle mistaken. Birch has recently argued that this whole problem can be avoided through his proposal of universal consideration in a “root sense,” which applies to all beings, with no exceptions marked by any of (...) the criteria proposed by others. I argue that the strengths of this proposal are its openness to new value discoveries and its focus on agents’ practices. Its flaw is its failure to account convincingly for how values are ever formulated or obligations generated. Hence, it does not represent a viable alternative to the approach he rejects. However, rather than return to that approach, I suggest that Birch’s own line of argument could be developed more consistently if, from his starting point of “deontic experience,” one were to develop an explicitly deontological ethic that focuses more decisively on moral consideration as opposed to moral considerability.

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 paper has three aims. First, I defend, in its most radical form, Hume's scepticism about practical reason, as it applies to purely self-regarding matters. It's not always irrational to discount the future, to be inconstant in one's preferences, to have incompatible desires, to not pursue the means to one's ends, or to fail to maximize one's own good. Second, I explain how our response to the “irrational” agent should be understood as an expression of frustrated sympathy, in Adam Smith's (...) sense of sympathy, rather than a genuine judgement about Reason. We judge these people because we cannot imaginatively identify with their desires and attitudes, and this is frustrating. Third, compared to the standard cognitive view, my account better explains the nature of our criticism of the “irrational,” and, by portraying “irrationality” as a cause of upset to other people, provides a better normative basis for being “rational.”.

Develops a logical analysis of dialogue in which two or more parties attempt to advance their own interests. It includes a classification of the major types of dialogues and a discussion of several important informal fallacies.

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 term disinformation is generally used to refer to information that is false and harmful, by contrast with misinformation (false but harmless) and malinformation (harmful but true); disinformation is also generally understood to involve coordination and to be intentionally false and/or harmful. However, particular studies rarely apply all these criteria when discussing cases. Doing so would involve applying at least three distinct problem framings: an epistemic framing to detect that a proposition in circulation is false, a behavioural framing to detect (...) the coordinated efforts at communicating that proposition, and a security framing to identify threats or risks of harm attendant on widespread belief in the proposition. As for the question of intentionality, different kinds of clues can be picked up within each framing, although none alone is likely to be conclusive. Yet particular studies tend to centre on or prioritise a single framing. Many today aim to make policy recommendations about combatting disinformation, and they prioritise security concerns over the demands of epistemic diligence. This carries a real risk of disinformation research being ‘weaponised’ against inconvenient truths. Against combative approaches, this article argues for a critical approach which recognizes the importance of epistemic diligence and transparency about normative assumptions. (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)

This book identifies 25 argumentation schemes for presumptive reasoning and matches a set of critical questions to each.

Experiences like pains, pleasures, and emotions have affective phenomenal character: they feel pleasant or unpleasant. Imperativism proposes to explain affective phenomenal character by appeal to imperative content, a kind of intentional content that directs rather than describes. We argue that imperativism is on the right track, but has been developed in the wrong way. There are two varieties of imperativism on the market: first-order and higher-order. We show that neither is successful, and offer in their place a new theory: reflexive (...) imperativism. Our proposal is that an experience P feels pleasant in virtue of being constituted by a Command with reflexive imperative content, while an experience U feels unpleasant in virtue of being constituted by a Command with reflexive imperative content : More of P!Less of U! If you need a slogan: experiences have affective phenomenal character in virtue of commanding us Get more of me! Get less of me! (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)

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.

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.

Walton gives a clear method for analyzing and evaluating cases of ad hominem arguments found in everyday argumentation.

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)

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.

_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 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)

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)

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.

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.

Affective experiences such as pains, pleasures, and emotions have affective phenomenology: they feel pleasant. This type of phenomenology has a loopy regulatory profile: it often motivates us to act a certain way, and these actions typically end up regulating our affective experiences back. For example, the pleasure you get by tasting your morning coffee motivates you to drink more of it, and this in turn results in you obtaining another pleasant gustatory experience. In this article, we argue that reflexive imperativism (...) is the only intentionalist account of affective phenomenology—probably, the only account at all—that is able to make sense of its loopy regulatory profile.
