Detailed studies of people who have experienced the Capgras delusion (the delusion that certain other people, usually close relatives, have been replaced by impostors) have led to advances in constructing an account which can deal with the basic symptomatology, testing alternative possibilities, generating and testing non‐trivial predictions, and broadening the scope of the basic account to encompass other delusions. This paper outlines these developments. It uses them to explore implications for understanding the formation and maintenance of beliefs, and to discuss (...) basic principles of what has come to be known as cognitive neuropsychiatry.

In their account of theory change in logic, Aberdein and Read distinguish 'glorious' from 'inglorious' revolutions--only the former preserves all 'the key components of a theory' [1]. A widespread view, expressed in these terms, is that empirical science characteristically exhibits inglorious revolutions but that revolutions in mathematics are at most glorious [2]. Here are three possible responses: 0. Accept that empirical science and mathematics are methodologically discontinuous; 1. Argue that mathematics can exhibit inglorious revolutions; 2. Deny that inglorious revolutions are (...) characteristic of science. Where Aberdein and Read take option 1, option 2 is preferred by Mizrahi [3]. This paper seeks to resolve this disagreement through consideration of some putative mathematical revolutions.

An array of new cases of lies is presented in support of the idea that lying does not require an intention to be deceptive. The crucial feature of these cases is that the agents who lie have some sort of motivation to lie alternative to an intention to be deceptive. Such alternative motivation comes in multiple varieties, such that we should think that the possibility of lying without an intention to be deceptive is common.

Until recently, discussion of virtues in the philosophy of mathematics has been fleeting and fragmentary at best. But in the last few years this has begun to change. As virtue theory has grown ever more influential, not just in ethics where virtues may seem most at home, but particularly in epistemology and the philosophy of science, some philosophers have sought to push virtues out into unexpected areas, including mathematics and its philosophy. But there are some mathematicians already there, ready to (...) meet them, who have explicitly invoked virtues in discussing what is necessary for a mathematician to succeed. In both ethics and epistemology, virtue theory tends to emphasize character virtues, the acquired excellences of people. But people are not the only sort of thing whose excellences may be identified as virtues. Theoretical virtues have attracted attention in the philosophy of science as components of an account of theory choice. Within the philosophy of mathematics, and mathematics itself, attention to virtues has emerged from a variety of disparate sources. Theoretical virtues have been put forward both to analyse the practice of proof and to justify axioms; intellectual virtues have found multiple applications in the epistemology of mathematics; and ethical virtues have been offered as a basis for understanding the social utility of mathematical practice. Indeed, some authors have advocated virtue epistemology as the correct epistemology for mathematics (and perhaps even as the basis for progress in the metaphysics of mathematics). This topical collection brings together several of the researchers who have begun to study mathematical practices from a virtue perspective with the intention of consolidating and encouraging this trend.

A list of resources for virtue theories of argumentation. Last updated October 31st, 2023.

What should a virtue theory of argumentation say about fallacious reasoning? If good arguments are virtuous, then fallacies are vicious. Yet fallacies cannot just be identified with vices, since vices are dispositional properties of agents whereas fallacies are types of argument. Rather, if the normativity of good argumentation is explicable in terms of virtues, we should expect the wrongness of bad argumentation to be explicable in terms of vices. This approach is defended through analysis of several fallacies, with particular emphasis (...) on the ad misericordiam. (shrink)

Deep disagreements are characteristically resistant to rational resolution. This paper explores the contribution a virtue theoretic approach to argumentation can make towards settling the practical matter of what to do when confronted with apparent deep disagreement, with particular attention to the virtue of courage.

The traditional view of evidence in mathematics is that evidence is just proof and proof is just derivation. There are good reasons for thinking that this view should be rejected: it misrepresents both historical and current mathematical practice. Nonetheless, evidence, proof, and derivation are closely intertwined. This paper seeks to tease these concepts apart. It emphasizes the role of argumentation as a context shared by evidence, proofs, and derivations. The utility of argumentation theory, in general, and argumentation schemes, in particular, (...) as a methodology for the study of mathematical practice is thereby demonstrated. Argumentation schemes represent an almost untapped resource for mathematics education. Notably, they provide a consistent treatment of rigorous and non-rigorous argumentation, thereby working to exhibit the continuity of reasoning in mathematics with reasoning in other areas. Moreover, since argumentation schemes are a comparatively mature methodology, there is a substantial body of existing work to draw upon, including some increasingly sophisticated software tools. Such tools have significant potential for the analysis and evaluation of mathematical argumentation. The first four sections of the paper address the relationships of evidence to proof, proof to derivation, argument to proof, and argument to evidence, respectively. The final section directly addresses some of the educational implications of an argumentation scheme account of mathematical reasoning. (shrink)

Virtue-based approaches have attracted significant recent interest in argumentation, including a recent anthology of Chinese translations of important articles in the field. In this article, adapted from the introduction to that anthology, we discuss the origins of virtue argumentation and some of the challenges it has faced, as well as attempt to provide an overview of recent work on the virtues and vices relevant to argumentation. In the final section we discuss the articles that were selected and motivate their selection.

A queue‐jumping argument concludes that some course of action is impermissible by likening it to the presumptively impermissible act of jumping a queue. Arguments of this sort may be found in a disparate range of contexts and in support of policies favoured by both left and right. Examples include arguments against private education and private health care but also arguments against accommodations for learning disabilities, refugee resettlement, and birthright citizenship. We infer that, although queue‐jumping arguments are strictly analogies, they constitute (...) a sufficiently distinct class of arguments to justify their separate treatment. The paper proposes an argumentation scheme for queue‐jumping arguments and demonstrates its applicability to some existing arguments of this type. (shrink)

I intend to bring recent work applying virtue theory to the study of argument to bear on a much older problem, that of disagreements that resist rational resolution, sometimes termed "deep disagreements". Just as some virtue epistemologists have lately shifted focus onto epistemic vices, I shall argue that a renewed focus on the vices of argument can help to illuminate deep disagreements. In particular, I address the role of arrogance, both as a factor in the diagnosis of deep disagreements and (...) as an obstacle to their mutually acceptable resolution. Arrogant arguers are likely to make any disagreements to which they are party seem deeper than they really are and arrogance impedes the strategies that we might adopt to resolve deep disagreements. As a case in point, since arrogant or otherwise vicious arguers cannot be trusted not to exploit such strategies for untoward ends, any policy for deep disagreement amelioration must require particularly close attention to the vices of argument, lest they be exploited by the unscrupulous.

Virtue theories have lately enjoyed a modest vogue in the study of argumentation, echoing the success of more far-reaching programmes in ethics and epistemology. Virtue theories of argumentation (VTA) comprise several conceptually distinct projects, including the provision of normative foundations for argument evaluation and a renewed focus on the character of good arguers. Perhaps the boldest of these is the pursuit of the fully satisfying argument, the argument that contributes to human flourishing. This project has an independently developed epistemic analogue: (...) eudaimonistic virtue epistemology. Both projects stress the importance of widening the range of cognitive goals beyond, respectively, cogency and knowledge; both projects emphasize social factors, the right sort of community being indispensable for the cultivation of the intellectual virtues necessary to each project. This paper proposes a unification of the two projects by arguing that the intellectual good life sought by eudaimonistic virtue epistemologists is best realized through the articulation of an account of argumentation that contributes to human flourishing.

The influence that philosophy of science has had on scientific practice is as controversial as it is undeniable, especially in the case of biology. The dynamic between philosophy and biology as disciplines has developed along two different lines that can be characterized as 'paternal', on the one hand, and more 'fraternal', on the other. The role Popperian principles of demarcation and falsifiability have played in both the systematics community as well as the ongoing evolution-creation debates illustrate these contrasting forms of (...) interdisciplinary engagement, underscoring the influence philosophy of science in shaping our contemporary understanding of biology in the North American context. However, a strict disciplinary distinction between philosophy and science may itself be a false dichotomy that risks hampering future development of the biological sciences. By actively engaging with philosophical considerations as an integral part of their scientific practice, nineteenth-century biologists offer an interesting counterpoint to current trends of overspecialization and provide a model of scientists who avoided extremes of antagonism with, or subservience to, philosophy.

Virtue theories of argumentation (VTA) emphasize the roles arguers play in the conduct and evaluation of arguments, and lay particular stress on arguers’ acquired dispositions of character, that is, virtues and vices. The inspiration for VTA lies in virtue epistemology and virtue ethics, the latter being a modern revival of Aristotle’s ethics. Aristotle is also, of course, the father of Western logic and argumentation. This paper asks to what degree Aristotle may thereby be claimed as a forefather by VTA.

Few automated legal reasoning systems have been developed in domains of law in which a judicial decision maker has extensive discretion in the exercise of his or her powers. Discretionary domains challenge existing artificial intelligence paradigms because models of judicial reasoning are difficult, if not impossible to specify. We argue that judicial discretion adds to the characterisation of law as open textured in a way which has not been addressed by artificial intelligence and law researchers in depth. We demonstrate that (...) systems for reasoning with this form of open texture can be built by integrating rule sets with neural networks trained with data collected from standard past cases. The obstacles to this approach include difficulties in generating explanations once conclusions have been inferred, difficulties associated with the collection of sufficient data from past cases and difficulties associated with integrating two vastly different paradigms. A knowledge representation scheme based on the structure of arguments proposed by Toulmin has been used to overcome these obstacles. The system, known as Split Up, predicts judicial decisions in property proceedings within family law in Australia. Predictions from the system have been compared to those from a group of lawyers with favourable results. (shrink)

If good argument is virtuous, then fallacies are vicious. Yet fallacies cannot just be identified with vices, since vices are dispositional properties of agents whereas fallacies are types of argument.

This approach is defended through case studies of several fallacies, with particular emphasis on the ad hominem.

It has been a decade since the phrase virtue argumentation was introduced, and while it would be an exaggeration to say that it burst onto the scene, it would be just as much of an understatement to say that it has gone unnoticed. Trying to strike the virtuous mean between the extremes of hyperbole and litotes, then, we can fairly characterize it as a way of thinking about arguments and argumentation that has steadily attracted more and more attention from argumentation (...) theorists. We hope it is neither too late for an introduction to the field nor too soon for some retrospective assessment of where things stand. (shrink)

Douglas Walton’s multitudinous contributions to the study of argumentation seldom, if ever, directly engage with argumentation in mathematics. Nonetheless, several of the innovations with which he is most closely associated lend themselves to improving our understanding of mathematical arguments. I concentrate on two such innovations: dialogue types (§1) and argumentation schemes (§2). I argue that both devices are much more applicable to mathematical reasoning than may be commonly supposed.

Ubiquitous healthcare is an emerging area of technology that uses a large number of environmental and patient sensors and actuators to monitor and improve patients' physical and mental condition. Tiny sensors gather data on almost any physiological characteristic that can be used to diagnose health problems. This technology faces some challenging ethical questions, ranging from the small-scale individual issues of trust and efficacy to the societal issues of health and longevity gaps related to economic status. It presents particular problems in (...) combining developing computer/information/media ethics with established medical ethics. This article describes a practice-based ethics approach, considering in particular the areas of privacy, agency, equity and liability. It raises questions that ubiquitous healthcare will force practitioners to face as they develop ubiquitous healthcare systems. Medicine is a controlled profession whose practise is commonly restricted by government-appointed authorities, whereas computer software and hardware development is notoriously lacking in such regimes.

Anonymous argumentation has recently been the focus of public controversy: flash points include the outing of pseudonymous bloggers by newspapers and the launch of an academic journal that expressly permits pseudonymous authorship. However, the controversy is not just a recent one—similar debates took place in the nineteenth century over the then common practice of anonymous journalism. Amongst the arguments advanced by advocates of anonymous argumentation in either era is the contention that it is essential if the widest range of voices (...) are to be heard; amongst the counterarguments of its critics, that it weakens the credibility of individual arguments and irresponsibly cheapens the standard of public discourse. This paper explores some implications of the controversy for the ethics of argumentation in general and virtue theories of argumentation in particular. (shrink)

Foucault never presented a systematic history of tragedy, but reflections on the relationship between tragedy and the will to truth are scattered throughout his writings. Given the Nietzschean inspiration of his work, this is not surprising. Yet Foucault rarely referenced The Birth of Tragedy, preferring to draw on Nietzsche’s later genealogical writings. In this paper I highlight the importance of The Birth of Tragedy for understanding Foucault’s entire corpus, suggesting that it can be read as a sustained consideration on the (...) political significance of the madness of Orestes from Aeschylus to Racine.

In this article I generalize ecological theory by developing the notion of separate but linked ecologies. I characterize an ecology by its set of actors, its set of locations, and the relation it involves between these. I then develop two central concepts for the linkage of ecologies: hinges and avatars. The first are issues or strategies that "work" in both ecologies at once. The second are attempts to institutionalize in one ecology a copy or colony of an actor in another. (...) The article investigates the first of these concepts using two detailed examples of hinge analysis between the professional and political ecologies. Both concern medical licensing, the first in 19th-century New York and the second in 19th-century England. For the avatar concept, the article analyzes four less detailed cases linking the professional and university ecologies: computer science, criminal justice, clinical psychology, and applied economics.

I want to say something about the sort of arguments that it is possible to lose, and whether losing arguments can be done well. I shall focus on losing philosophical arguments, and I will be talking about arguments in the sense of acts of arguing. This is the sort of act that one can perform on one’s own or with one other person in private. But in either of these cases it is difficult to win—or to lose. So I shall (...) concentrate on arguments with audiences. We may think of winning or losing such arguments in terms of whether the audience is convinced. Of course, this doesn’t necessarily have anything to do with who is in the right. That means that there are two sorts of loser: real losers, who lose the argument deservedly, because they are in the wrong, and mere losers, who lose the argument undeservedly, because they are in the right. Hence there must also be two sorts of winner: real winners, who win the argument deservedly, because they are in the right, and mere winners, who win the argument undeservedly, because they are in the wrong. An optimal outcome for arguments with losers would be if all the losers are real losers. (shrink)

In this chapter I argue that intellectual humility is related to argumentation in several distinct but mutually supporting ways. I begin by drawing connections between humility and two topics of long-standing importance to the evaluation of informal arguments: the ad verecundiam fallacy and the principle of charity. I then explore the more explicit role that humility plays in recent work on critical thinking dispositions, deliberative virtues, and virtue theories of argumentation.

Aggleton & Brown argue that a hippocampal-anterior thalamic system supports the “recollection” of contextual information about previous events, and that a separate perirhinal-medial dorsal thalamic system supports detection of stimulus “familiarity.” Although there is a growing body of human literature that is in agreement with these claims, when recollection and familiarity have been examined in amnesics using the process dissociation or the remember/know procedures, the results do not seem to provide consistent support. We reexamine these studies and describe the results (...) of an additional experiment using a receiver operating characteristic (ROC) technique. The results of the reanalysis and the ROC experiment are consistent with Aggleton & Brown's proposal. Patients with damage to both regions exhibit severe deficits in recollection and smaller, but consistent, deficits in familiarity. (shrink)

Austrian business cycle theory is a body of hypotheses embodying particularly Austrian insights and assumptions. The canonical variant associated with Ludwig von Mises and Friedrich A. Hayek is particularly well suited to the Great Depression. However, it is an inadequate account of the recent US recession and financial crisis. This chapter develops a suitable ABCT variant that explicitly incorporates not only the economy’s time structure of production but also its structure of consumption and its risk structure. The continuous input–continuous output (...) nature of the housing market is highlighted, along with the Treasury and the Federal Reserve’s roles in externalizing the risk associated with government-sponsored entities’ debt. The chapter then extends Roger Garrison’s graphical framework to illustrate this ABCT variant. (shrink)

Philosophers have devoted a great deal of time and energy to understanding and assessing the metaphysical and epistemological branches of Descartes' and Spinoza's philosophical systems, and deservedly so---they are arguably the most brilliant and innovative metaphysicians and epistemologists of the seventeenth century. The primary aim of this dissertation is to contribute to showing that their brilliance and innovation is also manifested in the ethical branch of their systems. ;Descartes is not known as a moral philosopher, but this reflects the interests (...) of his commentators more than it reflects Descartes' own interests. In his correspondence and in The Passions of the Soul, there is a fully developed theory of virtue. His theory of virtue, I believe, cannot be clearly understood outside the context of his theory of freedom of the will. So, in Chapter One, I present and defend an account of his theory of the will's freedom, and then, in Chapter Two, I examine his theory of virtue within the interpretive framework I develop in Chapter One. An important aim of Chapter Two is to show how his theory of virtue, an ethical doctrine, is connected with his theory of free will, a doctrine belonging to metaphysics. ;Spinoza, unlike Descartes, is known for his work in moral philosophy. But though his ethical views have not suffered the neglect that his predecessor's has, his ethical theory has not been accurately understood. Contrary to the orthodox Hobbesean interpretation, in Chapters Three and Four I construct and defend a rationalist interpretation of Spinoza's ethical theory. Like Plato and Kant and unlike Hobbes and Hume, I argue that, for Spinoza, reason is practical in two important senses: it is a source of motivation and it is a source of ethical prescriptions.

Spinoza’s moral philosophy is trending. This is the fourth book written in English in six years devoted to various aspects of it; that may not qualify as viral, but it is progress. The volume’s five essays cover moral responsibility, akrasia, moral realism, and Spinoza’s model of human nature: the free man. Hence its subtitle is misleading. There is nothing uniquely contemporary about the issues discussed, as is evident from the essays themselves. Also, the moral problems are not the type one (...) might expect. You will not find an analysis of Spinoza’s position on the moral status of non-human animals, for example. What you will find is an effort to bring Spinoza into contemporary debates.

Evidence has accumulated that rod activation under mesopic and scotopic light levels alters visual perception and performance. Here we review the most recent developments in the measurement of rod and cone contributions to mesopic color perception and temporal processing, with a focus on data measured using the four-primary photostimulator method that independently controls rod and cone excitations. We discuss the findings in the context of rod inputs to the three primary retinogeniculate pathways to understand rod contributions to mesopic vision. Additionally, (...) we present evidence that hue perception is possible under scotopic, pure rod-mediated conditions that involves cortical mechanisms. (shrink)

In Being and Worth Andrew Collier argues that beings both in the natural and human worlds have worth in themselves, whether we recognize it or not. He builds on recent work in critical realism to provide a reassessment of Spinoza's philosophy of mind and ethics. Conclusions are developed with particular reference to environmental ethics.

This paper proposes that virtue theories of argumentation and theories of visual argumentation can be of mutual assistance. An argument that adoption of a virtue approach provides a basis for rejecting the normative independence of visual argumentation is presented and its premisses analysed. This entails an independently valuable clarification of the contrasting normative presuppositions of the various virtue theories of argumentation. A range of different kinds of visual argument are examined, and it is argued that they may all be successfully (...) evaluated within a virtue framework, without invoking any novel virtues. (shrink)

In this new collection of essays, Andrew Feenberg argues that conflicts over the design and organization of the technical systems that structure our society shape deep choices for the future. A pioneer in the philosophy of technology, Feenberg demonstrates the continuing vitality of the critical theory of the Frankfurt School. He calls into question the anti-technological stance commonly associated with its theoretical legacy and argues that technology contains potentialities that could be developed as the basis for an alternative form (...) of modern society. Feenberg's critical reflections on the ideas of Jürgen Habermas, Herbert Marcuse, Jean-François Lyotard, and Kitaro Nishida shed new light on the philosophical study of technology and modernity. He contests the prevalent conception of technology as an unstoppable force responsive only to its own internal dynamic and politicizes the discussion of its social and cultural construction. This argument is substantiated in a series of compelling and well-grounded case studies. Through his exploration of science fiction and film, AIDS research, the French experience with the "information superhighway," and the Japanese reception of Western values, he demonstrates how technology, when subjected to public pressure and debate, can incorporate ethical and aesthetic values.

There has been little overt discussion of the experimental philosophy of logic or mathematics. So it may be tempting to assume that application of the methods of experimental philosophy to these areas is impractical or unavailing. This assumption is undercut by three trends in recent research: a renewed interest in historical antecedents of experimental philosophy in philosophical logic; a “practice turn” in the philosophies of mathematics and logic; and philosophical interest in a substantial body of work in adjacent disciplines, such (...) as the psychology of reasoning and mathematics education. This introduction offers a snapshot of each trend and addresses how they intersect with some of the standard criticisms of experimental philosophy. It also briefly summarizes the specific contribution of the other chapters of this book. (shrink)
