What does it mean to convince? In the pragma-dialectical theory of argumentation, convincing is done by arguments. The perlocutionary act of convincing is fundamentally related to the illocutionary act of arguing. I propose a critical reassessment of this relationship. The arguing-convincing pair presents conceptual difficulties, I argue, both in the pragmatic description based on felicity conditions and in the dialectical one based on intersubjective procedures. To tackle these problems, I develop a proposal that takes the speakers’ non-verbal (...) interaction with evidence, as opposed to their verbal interaction with one another, as the basis for understanding the resolution of differences of opinion. The proposal is compatible with the pragma-dialectical theory, provided some methodological adjustments are conceded. (shrink)

A convincing argument can change a discussant’s commitment regarding the acceptability of a claim, but the same effect can be achieved by examining evidence. Observing objects or events that count as evidence for or against the acceptability of a statement can change one’s commitment regarding that statement. If we speak of fallacies in the realm of convincing through argumentation, can we speak of fallacies in the realm of convincing through evidence? In this paper, we defend an affirmative (...) answer. We introduce and discuss the conceptual implications of evidentiary fallacies as fallacies committed when evidence is fabricated or suppressed during an attempt to resolve disagreement using proof. We then apply the notion of evidentiary fallacy to two real-life examples of mis-executed evidentiary procedures. We conclude that the notion of evidentiary fallacy can contribute to a more comprehensive fallacy theory and can foster new and broadly applicable critical skills. (shrink)

The nonrandom distribution of fears is not as clearly related to phylogenetically survival relevance as preparedness theory seems to imply. Although delayed extinction reflects some of the best human evidence for preparedness, even this phenomenon is not as robust as it once seemed to be. Apart from the evidence reviewed by Davey, recent studies from our laboratory provide further evidence for an expectancy bias model of selective associations.

Der Beitrag analysiert Techniken öffentlicher Gesundheitskommunikation und skizziert im Ausblick Minimalbedingungen für ihre ethische Vertretbarkeit. Dazu wird erstens an einem aktuellen Beispiel veranschaulicht, wie mittels Text und Bild die Öffentlichkeit überzeugt werden soll, ein bestimmtes Gesundheitsverhalten an den Tag zu legen. Zweitens werden anhand der internationalen Ethik-Debatte fünf Grundtypen von Techniken in der Gesundheitskommunikation (Information, Argumentation, Persuasion, Manipulation und Zwang) rekonstruiert und entlang von Mittel, Zweck, Folgen für Adressaten sowie Implikationen für Autonomie aus ethischer Sicht unterschieden. Am besonders ambivalenten Beispiel (...) der Persuasion wird dann drittens diskutiert, welche ethischen Fallstricke es bei Gesundheitskommunikation zu bedenken gibt. Schließlich zeigen wir argumentativ auf, dass es in sensiblen bioethischen Themenfeldern wichtig ist, zwischen verschiedenen Techniken der Gesundheitskommunikation analytisch zu differenzieren. Ziel sollte die Ermöglichung einer fairen und transparenten Diskussion für breite Bevölkerungsgruppen sein. (shrink)

Climate change compels us to rethink the ethics of our dietary choices and has become an interesting issue for ethicists concerned about diets, including animal ethicists. The defenders of veganism have found that climate change provides a new reason to support their cause because many animal-based foods have high greenhouse gas emissions. The new style of argumentation, the ‘climatic argument for veganism’, may benefit animals by persuading even those who are not concerned about animals themselves but worry about climate change. (...) The arguments about the high emissions of animal-based food, and a resulting moral obligation to abstain from eating such products, are an addition to the prior forms of argument for principled veganism grounded on the moral standing of, and concern for, nonhuman animals. In this paper, we examine whether the climatic argument for veganism is convincing. We propose a formulation for the amended version of the argument and discuss its implications and differences compared to the moral obligations of principled veganism. We also reflect upon the implications of our findings on agricultural and food ethics more generally. (shrink)

Numerical simulations have come to be widely used in scientific work. Like experiments, simulations generate large quantities of numbers that require analysis and constant concern with uncertainty and error. How do simulationists convince themselves, and others, about the credibility of output? The present analysis reconstructs the perspectives related to performing numerical simulations, in general, and the situations in which simulationists deal with uncertain output, in particular. Starting from a distinction between idealized and realistic simulations, the paper presents the principal methods (...) of evaluation in relation to these practices and how different audiences expect different methods. One major challenge in interpreting output data is to distinguish between “real” and “numerical” effects. Within the practice of idealized simulations, simulationists hold the underlying model accountable for results that manifest “real” effects, but because “numerical” and “real” effects cannot be distinguished on the basis of what they derive from, attempted causal explanations are rather justifications for their conclusions. At the same time, simulationists’ explanations are part and parcel of their contradictory perspectives, according to which they believe in simulations largely due to the underlying model, while painfully recognizing everything they have to add to make computations doable on the basis of this model.

One way to enhance rule compliance is to provide people with arguments explaining why the desired behavior is important. We argue that there might be another, potentially more effective way to enhance rule compliance: ask people to generate arguments in favor of the rule themselves, which can trigger a process of self-persuasion. We compared the effects of providing arguments, asking respondents to generate arguments themselves, and a combination of both approaches on rule compliance and the perceived importance of the rule. (...) A field experiment revealed that rule compliance was higher in all experimental conditions compared to a control condition, with the highest level of rule compliance in the conditions that either presented the arguments or asked people to generate arguments themselves. Yet the rule was only evaluated as more important compared to the control condition, when people generated arguments themselves. This study suggests that rule compliance and perceived importance of this rule can be enhanced by easy low-cost interventions. (shrink)

Our doxastic states are our belief-like states, and these include outright doxastic states and degreed doxastic states. The former include believing that p, having the opinion that p, thinking that p, being sure that p, being certain that p, and doubting that p. The latter include degrees of confidence, credences, and perhaps some phenomenal states. But we also have conviction (being convinced simpliciter that p) and degrees of conviction (being more or less convinced that p). This volume shows: how and (...) why all of the outright doxastic states mentioned above can be reduced to conviction thresholds; what degrees of conviction fundamentally are (degreed reliance-dispositions); why degrees of conviction are not credences; when suspending a belief is compatible with continuing to believe; and the surprising extent to which Kant endorsed the theory of conviction that emerges in this volume.

Most advice for sharpening our thinking skills concerns how to avoid bad arguments. But argument is only one of the two basic forms of reasoning. The other is explanation, and it is equally susceptible to abuse. You may already be familiar with certain forms of explanatory malfeasance. One of the best known is circular explanation, in which the stated cause is just a different way of describing the effect. Here I'd like to introduce you to a less appreciated error of (...) explanation. To my knowledge it has no widely accepted name, but I call it ???the convincing explanation??? (shrink)

This paper examines public meetings in the Netherlands where experts and officials interact with local residents on the human health effects of livestock farming. Using Conversation Analysis, we reveal a ‘weapon of the weak’: a practice by which the residents resist experts’ head start in information meetings. It is shown how residents draw on the given question-answer format to challenge experts and pursue an admission of, for example, methodological shortcomings. We show how the residents’ first question functions as a ‘foot-in-the-door’, (...) providing them with a strong basis for skepticism. By systematically challenging the expert responses, the residents exploit the interaction’s sequential organization, with the effect that the goal becomes them being convinced rather than being informed. Consequently, the withholding of consent becomes the residents’ ‘weapon’. Finally, we argue that in an age where expertise is increasingly contested, it is crucial to understand how, and to what end, this contestation may occur. (shrink)

Nearly all Disney movies represent to people mere possibilities. One can conceive of scenarios with genies, wooden puppets coming to life, flying elephants, and mermaids. And there certainly seems to be no special problem in conceiving of a scenario where all the author's experiences are a mere dream induced by a Maleficent‐like evil genius. The problem in the present context is that the possibility of a dream‐inducing Maleficent‐like evil genius guarantees that how things appear would be no different, whether she (...) is dreaming or not. But maybe there is a difference: does it not appear to her that there is a difference between dreaming and wakefulness? The very fact that she is aware of such a distinction at all suggests the distinction is real. People prefer a real life over an experientially identical dream life, or even a more pleasurable dream life, because there is more to life than just experience. (shrink)

Gemma Frisius (1508–1555), who worked at the university of Louvain, heard about the Copernican system already around 1530 and afterwards was a careful reader of the Narratio prima and the De Revolutionibus. The article argues that his posthumous preface to the Ephemerides (1556) by his pupil Stadius expresses his ultimate opinion on the system of the world. Moreover, it is also the only text where he tackles the epistemological problems of the question. A careful analysis of this preface shows that (...) at the end of his life, on the ground of observations as well as philosophical demands, he admitted at least the first two movements ascribed to the earth by Copernicus.

The aim of this article is to show the argumentative component in the discourse of teachers. This is done on the basis of an analysis of the argumentative strategies used by teachers during the first class of a university course in order to increase their discourse efficiency. The analysis of the corpus studied shows that in such a session teachers use argumentative strategies in order to control the social distance which separates them from students. In doing so, they make a (...) double movement, one of distancing and one of approximation, with the aim of achieving a balance which permits them to consolidate their authority in the eyes of the students and, at the same time, present an accessible and well-disposed image to them.

John organized a state lottery and his wife won the main prize. You may feel that the event of her winning wasn’t particularly random, but how would you argue that in a fair court of law? Traditional probability theory does not even have the notion of random events. Algorithmic information theory does, but it is not applicable to real-world scenarios like the lottery one. We attempt to rectify that.

I argued in ‘Pro‐life arguments against infanticide and why they are not convincing’ that arguments presented by pro‐life philosophers are mistaken and cannot show infanticide to be immoral. Several scholars have offered responses to my arguments. In this paper, I reply to my critics: Daniel Rodger, Bruce P. Blackshaw and Clinton Wilcox. I also reply to Christopher Kaczor. I argue that pro‐life arguments still are not convincing.

In contemporary paternalism literature, persuasion is commonly not considered paternalistic. Moreover, paternalism is typically understood to be problematic either because it is seen as coercive, or because of the insult of the paternalist considering herself superior. In this paper, I argue that doctors who persuade patients act paternalistically. Specifically, I argue that trying to persuade a patient (here understood as aiming for the patient to consent to a certain treatment, although he prefers not to) should be differentiated from trying to (...) convince him (here understood as aiming for the patient to want the treatment) and recommending (the doctor merely providing her professional opinion). These three forms of influence are illustrated by summaries of video-recorded hospital encounters. While convincing and recommending are generally not paternalistic, I argue that persuasion is what I call communicative paternalism and that it is problematic for two reasons. First, the patient’s preferences are dismissed as unimportant. Second, the patient might wind up undergoing treatment against his preferences. This does not mean that persuasion always should be avoided, but it should not be undertaken lightly, and doctors should be aware of the fine line between non-paternalism and paternalism. The fact that my analysis of paternalism differs from traditional accounts does not imply that I deem these to be wrong, but rather that paternalism should be considered as a more multi-faceted concept than previous accounts allow for.

A significant body of research concludes that stable beliefs of perceived consumer effectiveness lead to sustainable consumption choices. Consumers who believe that their decisions can significantly affect environmental and social issues are more likely to behave sustainably. Little is known, however, about how perceived consumer effectiveness can be increased. We find that feelings of guilt and pride, activated by a single consumption episode, can regulate sustainable consumption by affecting consumers’ general perception of effectiveness. This paper demonstrates the impact that guilt (...) and pride have on perceived consumer effectiveness and shows how this effect rests on the ability of these emotions to influence perceptions of agency. After experiencing guilt or pride, consumers see themselves as the cause of relevant sustainability outcomes. The process of causal attribution associated with these emotions influences consumers’ use of neutralization techniques. Through the reduction in consumers’ ability to neutralize their sense of personal responsibility, guilt and pride positively influence perceived consumer effectiveness. The inability to rationalize-away their personal responsibility, persuades consumers that they affect sustainability outcomes through their decisions. The research advances our understanding of sustainable consumption and identifies a new avenue for the regulation of individual consumer behavior that has significant implications for the development of sustainable marketing initiatives.

This paper argues that economics is epistemologically limited in at least two main ways: first, economics fails at managing uncertainty as effectively as natural sciences do; second, economics assumes that rational patterns of utility maximization are real just to ensure deduction within economic models. Hence, this paper maintains that the high level of abstraction from reality of economics limits its explanations of its constantly changing ontology, i.e. markets. In particular, this paper shows that the epistemological limitations of economics become evident (...) once two examples from today’s world are considered, namely: the substitution of physical labor with AI-powered machines; and the introduction of the so-called Universal Basic Income (UBI), i.e. governmental stipends paid to those citizens whose job has been replaced by machines. Importantly, this paper argues that if an economy were to reach to the point where machines run any sort of private or public business and humans earn only the UBI, then such a situation would represent a limit case for economics. Indeed, this paper finds that although machines would represent the perfect example of rational utility-maximizers, in such a limit situation standard economic theory would most likely fail at predicting long-term economic outcomes.

Mr. William Baumer, in his “Ontological Arguments Still Fail,” gives an acceptable account of Kant’s complicated reasoning about the ontological proof. I have been aware of these complications, including Kant’s own precritical ontological proof, for a good while, and in Anselm’s Discovery I deal with them at some length. I still do not see that Kant at any time stated the equivalent of Anselm’s stronger proof, or refuted it. Moreover, if I have oversimplified and weakened Kant’s case, the gap between (...) my account of that case and Kant’s cannot be larger than that between Baumer’s account of my countercase and the latter.

Argument quality has consistently been shown to have strong and lasting persuasive effects. The question is what criteria people use to distinguish strong from weak arguments and how these criteria relate to the ones proposed in normative argumentation theory. In an experiment 235 participants without training in argumentation theory rated the acceptance of 30 claims about the desirability of a consequence that were supported by either an argument from analogy, from authority, or from consequences. The supporting arguments were systematically manipulated (...) to violate argument type specific criteria. Participants proved sensitive to the violation of most, but not all, argument type specific criteria. From a normative perspective these findings suggest that people act in a fairly adequate way. These findings also enable a more precise description of what people may do when critically appraising arguments, which has important implications for the use of argument quality as a methodological tool in persuasion research.

Causalism is the thesis that natural selection can cause evolution. A standard argument for causalism involves showing that a hypothetical intervention on some population-level property that is identified with natural selection will result in evolution. In a pair of articles, one of which recently appeared in the pages of this journal, Jun Otsuka has put forward a quite different argument for causalism. Otsuka attempts to show that natural selection can cause evolution by considering a hypothetical intervention on an individual-level property. (...) Specifically, Otsuka identifies natural selection with the causal relationship between a trait and fitness, claims an intervention on the strength of this relationship can cause evolution, then concludes that natural selection can cause evolution. Below I describe why Otsuka’s argument for causalism is unconvincing. Central to my criticism is that Otsuka’s argument works only if one adopts an indefensible account of natural selection, according to which natural selection can occur in the absence of trait or fitness variation. I go on to explain why any attempt to demonstrate the truth of causalism via a hypothetical intervention on an individual-level property would appear to require one to adopt an account of natural selection that is inadequate for the same reason. This in turn means the plausibility of causalism does indeed depend on the plausibility of the claim that population-level properties, which supervene on the properties of the individuals in the population, can be causally efficacious.

In ‘Pro-life arguments against infanticide and why they are not convincing’ Joona Räsänen argues that Christopher Kaczor's objections to Giubilini and Minerva's position on infanticide are not persuasive. We argue that Räsänen's criticism is largely misplaced, and that he has not engaged with Kaczor's strongest arguments against infanticide. We reply to each of Räsänen's criticisms, drawing on the full range of Kaczor's arguments, as well as adding some of our own.

Many people have claimed that integrity requires sticking to one's convictions come what may. Greg Scherkoske challenges this claim, arguing that it creates problems in distinguishing integrity from fanaticism, close-mindedness or mere inertia. Rather, integrity requires sticking to one's convictions to the extent that they are justifiable and likely to be correct. In contrast to traditional views of integrity, Scherkoske contends that it is an epistemic virtue intimately connected to what we know and have reason to believe, rather than an (...) essentially moral virtue connected to our values. He situates integrity in the context of shared cognitive and practical agency and shows that the relationship between integrity and impartial morality is not as antagonistic as many have thought - which has important implications for the 'integrity objection' to impartial moral theories. This original and provocative study will be of great interest to advanced students and scholars of ethics. (shrink)

Thesis (MA)--Stellenbosch University, 2014.

BOOK REVIEW Extract: Integrity, it seems, is a matter of remaining true to oneself, or rather, it is a matter of remaining true to what one reasonably judges to be the best of oneself. In Integrity and the Virtues of Reason, Greg Scherkoske seeks to overturn this piece of conventional wisdom. It is a fine book and I learned a lot from it. Scherkoske elaborates and defends the idea that integrity is an epistemic virtue; that it is not fundamentally a (...) matter of being true to oneself but of being a good and responsible epistemic agent. What is wrong with the conventional picture, Scherkoske thinks, is that it invites moral danger. The moral danger Scherkoske has in mind takes two forms. One is self-indulgence. When faced with demands from others, fidelity to one's own commitments just because they are one's own can easily lead to a promotion of one's own interests over the interests of others. The second danger is blind allegiance. "Even if a person's commitments cannot be construed as self-indulgent or egoistic, an individual's belief that something is a matter of integrity might be taken to foreclose the possibility of challenge and revision".

An important artistic topic of Italian Renaissance painting was the rendering of the human figure. As leading actors in a painted narrative, figures had to convince beholders of the reality of the matter depicted with appropriated attitudes and gestures. This article is about two ways of drawing or rather constructing the human figure artists developed to achieve this goal. The first was only an adaptation to an old method: because of the rather simple and coarse elements used, constructions often resulted (...) in faulty pictures and were for that matter often criticized. As this article will show, the second method involved a new and very successful drawing skill, which not just required a different kind of knowledge of visual forms but of procedures of moving the hand, too.

Computational modeling of the brain holds great promise as a bridge from brain to behavior. To fulfill this promise, however, it is not enough for models to be 'biologically plausible': models must be structurally accurate. Here, we analyze what this entails for so-called psychobiological models, models that address behavior as well as brain function in some detail. Structural accuracy may be supported by (1) a model's a priori plausibility, which comes from a reliance on evidence-based assumptions, (2) fitting existing data, (...) and (3) the derivation of new predictions. All three sources of support require modelers to be explicit about the ontology of the model, and require the existence of data constraining the modeling. For situations in which such data are only sparsely available, we suggest a new approach. If several models are constructed that together form a hierarchy of models, higher-level models can be constrained by lower-level models, and low-level models can be constrained by behavioral features of the higher-level models. Modeling the same substrate at different levels of representation, as proposed here, thus has benefits that exceed the merits of each model in the hierarchy on its own. (shrink)

In the era of speed and development, electronic advertisements have emerged as a very important tool in marketing products and services due to their rapid spread and simplicity. In this research, the role of electronic advertisements in persuading young people in Iraq to purchase goods and services was identified. Based on the descriptive approach, a questionnaire containing 20 paragraphs was designed to measure the role of electronic advertisements in persuading young people. The Cronbach's alpha for the scale was calculated and (...) was equal to 82%. The sample included 360 young men and women from Iraq, where the questionnaires were distributed electronically and 351 valid questionnaires were retrieved for analysis. Based on statistical processing of the information, the study concluded that: There is a statistically significant relationship between electronic advertisements and persuading young people to purchase goods and services in Iraq, as the Pearson value reached 0.74.
