Defining relationships and limiting power: two leaders of Australian nursing, 1868–1904 This paper analyses aspects of the relationship between nursing and medicine during 1868–1904, in terms of power, gender and authority. A biographical approach is used with a focus on two leading nurses in Australia and their relationship with two leading medical practitioners. The first nurse is Lucy Osburn, the figurehead of the first generation of Nightingale nursing in Australia. The second nurse represents the second generation when Nightingale nursing had (...) largely won acceptance and was firmly established in Australian hospitals: she is Susan McGahey. Their main medical antagonists were Dr Alfred Roberts and Dr Anderson Stuart. A struggle over the control of nursing is evident in these relationships. The outcome transcended personalities, greatly influenced the structure of modern nursing, and marked the rising tide of medical domination in Australia. (shrink)

The standard account of denying the antecedent (DA) is that it is a deductively invalid form of argument, and that, in a conditional argument, to argue from the falsity of the antecedent to the falsity of the consequent is always fallacious. In this paper, we argue that DA is not always a fallacious argumentative strategy. Instead, there is a legitimate usage of DA according to which it is a defeasible argument against the acceptability of a claim. The dialectical effect of (...) denying the antecedent is to shift the burden of proof back to the original proponent of a claim. We provide a model of this non-fallacious usage which is built upon pragmatic models of argumentation. (shrink)

This paper considers the question of whether Mill's account of the nature and justificatory foundations of deductive logic is psychologistic. Logical psychologism asserts the dependency of logic on psychology. Frequently, this dependency arises as a result of a metaphysical thesis asserting the psychological nature of the subject matter of logic. A study of Mill's System of Logic and his Examination reveals that Mill held an equivocal view of the subject matter of logic, sometimes treating it as a set of psychological (...) processes and at other times as the objects of those processes. The consequences of each of these views upon the justificatory foundations of logic are explored. The paper concludes that, despite his providing logic with a prescriptive function, and despite his avoidance of conceptualism, Mill's theory fails to provide deductive logic with a justificatory foundation that is independent of psychology.

While courts depend on expert opinions in reaching sound judgments, the role of the expert witness in legal proceedings is associated with a litany of problems. Perhaps most prevalent is the question of under what circumstances should testimony be admitted as expert opinion. We review the changing policies adopted by American courts in an attempt to ensure the reliability and usefulness of the scientific and technical information admitted as evidence. We argue that these admissibility criteria are best seen in a (...) dialectical context as a set of critical questions of the kind commonly used in models of argumentation. (shrink)

This article examines the development of Russell's treatment of propositions, in relation to the topic of psychologism. In the first section, we outline the concept of psychologism, and show how it can arise in relation to theories of the nature of propositions. Following this, we note the anti-psychologistic elements of Russell's thought dating back to his idealist roots. From there, we sketch the development of Russell's theory of the proposition through a number of its key transitions. We show that Russell, (...) in responding to a variety of different problems relating to the proposition, chose to resolve these problems in ways that continually made concessions to psychologism.

Boethius's Consolation of Philosophy, written in Latin around 525 A.D., was to become one of the most influential literary texts of the Middle Ages. The Old English prose translation and adaptation which was produced around 900 and claims to be by King Alfred was one of the earliest signs of its importance and use, and the subsequent rewriting of parts as verse show an interest in rivalling the literary shape of the Latin original. The many changes and additions have much (...) to tell us about Anglo-Saxon interests and scholarship in the Alfredian period. This new edition is the first to present the second prose-and-verse version of the Old English text, and allows it to be read alongside the original prose version, for which this is the first edition for over a century, and the introduction and commentary reveal much about the history of the text and its composition. The edition contains critical texts of both versions; a translation; a full introduction examining the manuscripts, the composition of the prose text and of the subsequent verse, the language, the authorship and date of the two versions, the relationship to other texts of the period and later uses of it, and the nature and purpose of the work; a detailed commentary exploring the relationship to the Latin text and to the early medieval commentary tradition; textual notes; and a glossary.

Schopenhauer is famously abusive toward his philosophical contemporary and rival, Friedrich William Joseph von Schelling. This chapter examines the motivations for Schopenhauer’s immoderate attitude and the substance behind the insults. It looks carefully at both the nature of the insults and substantive critical objections Schopenhauer had to Schelling’s philosophy, both to Schelling’s metaphysical description of the thing-in-itself and Schelling’s epistemic mechanism of intellectual intuition. It concludes that Schopenhauer’s substantive criticism is reasonable and that Schopenhauer does in fact avoid Schelling’s errors: (...) still, the vehemence of the abuse is best perhaps explained by the proximity of their philosophies, not the distance. Indeed, both are developing metaphysics of will with full and conflicted awareness of the Kantian epistemic strictures against metaphysics. In view of this, Schopenhauer is particularly concerned to mark his own project as legitimate by highlighting the manner in which he avoids Schelling’s errors. (shrink)

In this chapter, we explore the development and importance of the connection between argumentation and artificial intelligence. Specifically, we show that the influence of argumentation on AI has occurred within a framework that is consistent with the basic approach of Pragma-Dialectics. While the pragma-dialectical approach is typically conceived of as applying primarily to argumentation occurring between human agents, we show that the basic features of this approach can consistently be applied in a virtual context, whereby the goal-directed activities of, and (...) exchanges of information between, artificial agents are regulated by procedural rules.

This paper examines the views of Fogelin, Woods, Johnstone, etc., concerning deep disa-greements, force-five standoffs, philosophical controversies, etc. My approach is to reconstruct their views and critiques of them as meta-arguments, and to elaborate the meta-argumentative aspects of radical disa-greements. It turns out that deep disagreements are resolvable to a greater degree than usually thought, but only by using special principles and practices, such as meta-argumentation, ad hominem argumentation, Ramsey’s principle, etc.

Questioning the dominant view that Deleuze and Merleau-Ponty have little of substance in common, Judith Wambacq draws on unpublished primary sources and current scholarship in English and French to bring them into a compelling dialogue to reveal a shared concern with the transcendental conditions of thought.

The paper considers contemporary models of presumption in terms of their ability to contribute to a working theory of presumption for argumentation. Beginning with the Whatelian model, we consider its contemporary developments and alternatives, as proposed by Sidgwick, Kauffeld, Cronkhite, Rescher, Walton, Freeman, Ullmann-Margalit, and Hansen. Based on these accounts, we present a picture of presumptions characterized by their nature, function, foundation and force. On our account, presumption is a modal status that is attached to a claim and has the (...) effect of shifting, in a dialogue, a burden of proof set at a local level. Presumptions can be analysed and evaluated inferentially as components of rule-based structures. Presumptions are defeasible, and the force of a presumption is a function of its normative foundation. This picture seeks to provide a framework to guide the development of specific theories of presumption. (shrink)

Analogical reasoning projects a property taken to hold of something or things (the source) to something else (the target) on the basis of just those similarities premised in the analogy. Standard similarity-based accounts of analogical reasoning face the question: Under what conditions does a collection of similarities sufficiently warrant analogical projection? One answer is: When a thing’s having the premised similarities somehow determines its having the projected property. Standardly, this answer has been interpreted as claiming that a formally defined determination (...) relation exists between the variables of which the determining properties are values and the variable of which the determined property is a value. This paper supplies another answer: Analogical projection is warranted when an item’s having the projected property is grounded in its having the premised similarities. Drawing on the metaphysics of grounding, we propose a model of grounded analogy on which analogical reasoning is valid under metaphysical necessity. Our model thus provides one answer to John Stuart Mill’s question of how analogical reasoning based on limited information about a single source case can provide an indefeasible justification for analogical projection. Once a relation of total grounding is ascertained to hold between some similarities and the projected property, no other properties bear on the projectability of the projected property from the source to the target.

Adversariality in argumentation is typically theorized as inhering in, and applying to, the interactional roles of proponent and opponent that arguers occupy. This paper considers the kinds of adversariality located in the conversational roles arguers perform while arguing—specifically listening. It begins by contending that the maximally adversarial arguer is an arguer who refuses to listen to reason by refusing to listen to another’s reasons. It proceeds to consider a list of lousy listeners in order to illustrate the variety of ways (...) that the conversational role of listener can be performed adversarially. Because conversational roles, while not adversarial by nature, can be enacted adversarially, arguers are properly subject to praise and blame for their performances of these roles. Thus, the paper concludes, argumentation theory stands in need of an articulated normative vocabulary and theory to codify, apply, explain, and justify the norms of listening governing, guiding, and appraising arguers’ performances of listening in argumentation.

This paper offers a probabilistic treatment of the conditions for argument cogency as endorsed in informal logic: acceptability, relevance, and sufficiency. Treating a natural language argument as a reason-claim-complex, our analysis identifies content features of defeasible argument on which the RSA conditions depend, namely: change in the commitment to the reason, the reason’s sensitivity and selectivity to the claim, one’s prior commitment to the claim, and the contextually determined thresholds of acceptability for reasons and for claims. Results contrast with, and (...) may indeed serve to correct, the informal understanding and applications of the RSA criteria concerning their conceptual dependence, their function as update-thresholds, and their status as obligatory rather than permissive norms, but also show how these formal and informal normative approachs can in fact align.

In “The logic of deep disagreements” (Informal Logic, 1985), Robert Fogelin claimed that there is a kind of disagreement – deep disagreement – which is, by its very nature, impervious to rational resolution. He further claimed that these two views are attributable to Wittgenstein. Following an exposition and discussion of that claim, we review and draw some lessons from existing responses in the literature to Fogelin’s claims. In the final two sections (6 and 7) we explore the role reason can, (...) and sometimes does, play in the resolution of deep disagreements. In doing this we discuss a series of cases, mainly drawn from Wittgenstein, which we take to illustrate the resolution of deep disagreements through the use of what we call “rational persuasion.” We conclude that, while the role of argumentation in “normal” versus “deep” disagreements is characteristically different, it plays a crucial role in the resolution of both.

Two visual world experiments investigated the processing of the implicature associated with some using a “gumball paradigm.” On each trial, participants saw an image of a gumball machine with an upper chamber with orange and blue gumballs and an empty lower chamber. Gumballs dropped to the lower chamber, creating a contrast between a partitioned set of gumballs of one color and an unpartitioned set of the other. Participants then evaluated spoken statements, such as “You got some of the blue gumballs.” (...) Experiment 1 investigated the time course of the pragmatic enrichment from some to not all when the only utterance alternatives available to refer to the different sets were some and all. In Experiment 2, the number terms two, three, four, and five were also included in the set of alternatives. Scalar implicatures were delayed relative to the interpretation of literal statements with all only when number terms were available. The results are interpreted as evidence for a constraint-based account of scalar implicature processing. (shrink)

Debate about the responsibilities of affluent people to act to lessen global poverty has dominated ethics and political philosophy for forty years. But the controversy has reached an impasse, with the main approaches either demanding too much of ordinary mortals or else letting them off the hook. In Distant Strangers I show how a preoccupation with standard moral theories and with the concepts of duty and obligation have led philosophers astray. I argue that there are serious limits to what can (...) be demanded of ordinary human beings, but that this does not mean we must abandon the moral imperative to reduce poverty. Drawing on findings from behavioral economics and psychology, I show how we can motivate better-off people to lessen poverty without excessively taxing their moral virtue. And I argue that this approach is not just pragmatically but morally appropriate. (shrink)

Different approaches analyze the strength of a natural language argument in different ways. This paper contrasts the dialectical, structural, probabilistic (or Bayesian), computational, and empirical approaches by exemplarily applying them to a single argumentative text (Epicureans on Squandering Life; Aikin & Talisse, 2019). Rather than pitching these approaches against one another, our main goal is to show the room for fruitful interaction. Our focus is on a dialectical analysis of the squandering argument as an argumentative response that voids an interlocutor’s (...) right to assertion. This analysis addresses the pragmatic dimensions of arguing and implies an argument structure that is consistent with empirical evidence of perceived argument strength. Results show that the squandering argument can be evaluated as a (non-fallacious) ad hominem argument, which however is not necessarily stronger than possible arguments attacking it. (shrink)

The Nature and Status of Critical Questions in Argumentation Schemes.

In this paper we show how dialogue-based theories of argumentation can contribute to the construction of effective systems of dispute resolution. Specifically we consider the role of persuasion in online dispute resolution by showing how persuasion dialogues can be functionally embedded in negotiation dialogues, and how negotiation dialogues can shift to persuasion dialogues. We conclude with some remarks on how persuasion dialogues might be modelled is such a way as to allow them to be implemented in a mechanical or computerized (...) system of dialogue or dialogue management.

How is intellectual virtue related to critical thinking? Can one be a critical thinker without exercising intellectual virtue? Can one be intellectually virtuous without thereby being a critical thinker? How should our answers to these questions inform the instruction of critical thinking?

This brief commentary introduces their respective papers, which appear in the current issue of Informal Logic.

Our meta-argumentative vocabulary supplies the conceptual tools used to reflectively analyse, regulate, and evaluate our argumentative performances. Yet, this vocabulary is susceptible to misunderstanding and abuse in ways that make possible new discursive mistakes and pathologies. Thus, our efforts to self-regulate our reason-transacting practices by articulating their norms makes possible new ways to violate and flout those very norms. Scott Aikin identifies the structural possibility of this vicious feedback loop as the Owl of Minerva Problem. In the spirit of a (...) shared concern for the flourishing or our rational, argumentative practices, this paper approaches the Owl of Minerva Problem from a vantage point that, by comparison with Aikin’s, affords perspectives that are more pessimistic in some aspects and more optimistic in others. Pessimistically, the problem at the root of the weaponization of our meta-argumentative vocabulary is motivational, not structural. Its motivational nature explains its resistance to the normal repertoire of reparative argumentative maneuvers, as well as revealing a profound and deeply entrenched misunderstanding of the connection between our reasons-transacting practices and the goods achievable within them. Optimistically, in the absence of this motivational problem, the misunderstandings and errors made possible by our meta-argumentative vocabularies are amenable to remedy by familiar techniques of discursive instruction and repair. More optimistically, even though our meta-argumentative vocabularies are generated only retrospectively, they can be used prospectively, thereby making possible an aspirational motivation resulting in a virtuous cycle of increasingly autonomous normative self-regulation. Properly harnessed, the Owl of Minerva releases the Lark of Arete. (shrink)

This interview with the philosopher Bernard Stiegler was conducted in Paris on 28 January 2015, and first appeared in Dutch translation in the journal De uil van Minerva. The conversation begins by discussing the fundamental place occupied by the concept of ‘technics’ in Stiegler’s work, and how the ‘constitutivity’ of technics does and does not relate to Kant and Husserl. Stiegler is then asked about his relationship with Deleuze, and he responds by focusing on the concept of quasi-causality, but also (...) by arguing that there is a certain trajectory in Deleuze’s thought, situating his own philosophy in relation to its various moments. Stiegler is then asked to respond to the Charlie Hebdo terrorist attacks carried out three weeks prior to the interview. After making a couple of precautionary remarks, Stiegler relates such occurrences to the problem of what he calls ‘spiritual poverty’, to the intensification of ‘negative sublimation’ that can occur when there is a disconnection between the generations, and more generally to the growth of nihilism. All of these phenomena relate to the exploitation of technology by a virulent capitalism that irrationally believes that only the market is rational. After consideration of the complex historical relationship between Islam and modernization, and of both of these to Nietzsche’s ‘death of God’, and after recalling the destructive role played by the West in the rise of fundamentalism and jihadism, Stiegler concludes by reflecting on the fact that, ultimately, ‘intellectuals’ have failed to use technologies in ways that produce alternatives to consumerism.

Disputational models of argumentation have been criticized as introducing adversariality into argumentation by mistakenly conceiving of it as minimally adversarial, and, in doing so, structurally incentivizing ancillary adversariality. As an alternative, non-adversarial models of argumentation like inquiry have been recommended. In this article I defend disputational, minimally adversarial models of disagreement-based argumentation. First, I argue that the normative kernel of minimal adversariality is properly located in the normative fabric of disagreement, not our practices of disputation. Thus, argumentation’s minimal adversariality is (...) a hereditary, rather than an acquired, trait. Second, I show how attempts to model disagreement-based argumentation non-adversarially, as co-inquiry, misrepresent the normative commitments of disagreers. Indeed, such attempts backfire in their efforts to make argumentation less adversarial, by removing the normative, discursive mechanisms by which we may hold each other to rational account for our commitments. Finally, I show how regulative models of disputation, like the Pragma-Dialectical critical discussion, are designed to minimize ancillary adversariality thereby preventing its escalation. (shrink)

Two decades of research on euthanasia in the Netherlands have resulted into clear insights in the frequency and characteristics of euthanasia and other medical end-of-life decisions in the Netherlands. These empirical studies have contributed to the quality of the public debate, and to the regulating and public control of euthanasia and physician-assisted suicide. No slippery slope seems to have occurred. Physicians seem to adhere to the criteria for due care in the large majority of cases. Further, it has been shown (...) that the majority of physicians think that the euthanasia Act has improved their legal certainty and contributes to the carefulness of life-terminating acts. In 2005, eighty percent of the euthanasia cases were reported to the review committees. Thus, the transparency envisaged by the Act still does not extend to all cases. Unreported cases almost all involve the use of opioids, and are not considered to be euthanasia by physicians. More education and debate is needed to disentangle in these situations which acts should be regarded as euthanasia and which should not. Medical end-of-life decision-making is a crucial part of end-of-life care. It should therefore be given continuous attention in health care policy and medical training. Systematic periodic research is crucial for enhancing our understanding of end-of-life care in modern medicine, in which the pursuit of a good quality of dying is nowadays widely recognized as an important goal, in addition to the traditional goals such as curing diseases and prolonging life.

A problem for dialogue models of argumentation is to specify a set of conditions under which an opponent’s claims, offered in support of a standpoint under dispute, ought to be challenged. This project is related to the issue of providing a set of acceptability conditions for claims made in a dialogue.

We propose a third (...) condition that attempts to mark a middle ground between suspicion and trust. (shrink)

Working within the broad lines of general consensus that mark out the core features of John Stuart Mill’s (1806–1873) logic, as set forth in his A System of Logic (1843–1872), this chapter provides an introduction to Mill’s logical theory by reviewing his position on the relationship between induction and deduction, and the role of general premises and principles in reasoning. Locating induction, understood as a kind of analogical reasoning from particulars to particulars, as the basic form of inference that is (...) both free-standing and the sole load-bearing structure in Mill’s logic, the foundations of Mill’s logical system are briefly inspected. Several naturalistic features are identified, including its subject matter, human reasoning, its empiricism, which requires that only particular, experiential claims can function as basic reasons, and its ultimate foundations in ‘spontaneous’ inference. The chapter concludes by comparing Mill’s naturalized logic to Russell’s (1907) regressive method for identifying the premises of mathematics. (shrink)

In a series of recent papers beginning with their “Splitting a difference of opinion: The shift to negotiation” Jan Albert van Laar and Erik Krabbe claim that it is sometimes reasonable to shift from a critical discussion to a negotiation in order to settle a difference of opinion. They argue that their proposal avoids the fallacies of bargaining and middle ground. Against this permissive policy for shifting to negotiation, we argue that the motivating reasons for such shifts typically fail, and (...) that the permissive policy avoids neither fallacy while structurally incentivizing two types of strategic maneuvering that constitute rational and argumentative hazards: argumentative overcharge and abandonment of discussion.

This paper argues against the priority of pure, virtue-based accounts of argumentative norms [VA]. Such accounts are agent-based and committed to the priority thesis: good arguments and arguing well are explained in terms of some prior notion of the virtuous arguer arguing virtuously. Two problems with the priority thesis are identified. First, the definitional problem: virtuous arguers arguing virtuously are neither sufficient nor necessary for good arguments. Second, the priority problem: the goodness of arguments is not explained virtuistically. Instead, being (...) excellences, virtues are instrumental in relation to other, non-aretaic goods—in this case, reason and rationality. Virtues neither constitute reasons nor explain their goodness. Two options remain for VA: either provide some account of reason and rationality in virtuistic terms, or accept them as given but non-aretaic goods. The latter option, though more viable, demands the concession that VA cannot provide the core norms of argumentation theory. (shrink)

This paper examines the adequacy of commitment change, as a measure of the successful resolution of a difference of opinion. I argue that differences of opinion are only effectively resolved if commitments undertaken in argumentation survive beyond its conclusion and go on to govern an arguer’s actions in everyday life, e.g., by serving as premises in her practical reasoning. Yet this occurs, I maintain, only when an arguer’s beliefs are changed, not merely her commitments.
