Ioana Grancea ABSTRACT: Ethotic arguments are defined as sequences of claims-and-reasons regarding speaker character, based on which the plausibility of speaker assertions can be questioned. This is an exploratory study concerning the role of visuals in ethotic arguing. In this paper, I bring together contributions from visual argumentation theory and from studies regarding various modes of...

In this paper, it is shown how formal dialectic can be extended to model multi-agent argumentation in which each participant is an agent. An agent is viewed as a participant in a dialogue who not only has goals, and the capability for actions, but who also has stable characteristics of types that can be relevant to an assessment of some of her arguments used in that dialogue. When agents engage in argumentation in dialogues, each agent has a credibility function that (...) can be adjusted upwards or downwards by certain types of arguments brought forward by the other agent in the dialogue. One type is the argument against the person or argumentum ad hominem, in which personal attack on one party's character is used to attack his argument. Another is the appeal to expert opinion, traditionally associated with the informal fallacy called the argumentum ad verecundiam. In any particular case, an agent will begin a dialogue with a given degree of credibility, and what is here called the credibility function will affect the plausibility of the arguments put forward by that agent. In this paper, an agent is shown to have specific character traits that are vital to properly judging how this credibility function should affect the plausibility of her arguments, including veracity, prudence, sincerity and openness to opposed arguments. When one of these traits is a relevant basis for an adjustment in a credibility function, there is a shift to a subdialogue in which the argumentation in the case is re-evaluated. In such a case, it is shown how the outcome can legitimately be a reduction in the credibility rating of the arguer who was attacked. Then it is shown how the credibility function should be brought into an argument evaluation in the case, yielding the outcome that the argument is assigned a lower plausibility value. (shrink)

The aim of this paper is to provide a model that allows the representation and analysis of circularity in ethotic structures, i.e. in communication structures related to the speaker’s character and in particular, his credibility. The paper studies three types of cycles: in self-referential sentences, embedded testimony and ethotic begging the question. It is shown that standard models allow the reconstruction of the circularities only if those circular utterances are interpreted as ethotic arguments. Their alternative, assertive interpretation (...) requires enriching the existing models with a purely ethotic component related to the credibility of the performer of any (not necessarily argumentative) speech act.

Perelman’s view of the role of persons in argument is one of the most distinctive features of his break with Cartesian assumptions about reasoning. Whereas the rationalist paradigm sought to minimize or eliminate personal considerations by dismissing them as distracting and irrelevant, Perelman insists that argumentation inevitably does and ought to place stress on the specific persons engaged in an argument and that the relationship between speaker and what is spoken is always relevant and important. In taking this (...) position, Perelman implicitly revives the classical conception of proof by character (ethos or “ethotic” argument), but despite an extended discussion of act and person in argument, The New Rhetoric does not give much consideration to the classical concept and confuses differing approaches to it within the tradition. The result is that Perelman treats the role of the speaker in argument only by reference to abstract techniques and does not recognize the importance of examining particular cases in order to thicken understanding of how ethotic argument works in the complex, situated context of its actual use. Consequently, Perelman’s account of the role of persons in argument should be supplement by reference to case studies, and to that end, I consider ethotic argument in W.E.B. Du Bois’ famous essay “Of Mr. Booker T. Washington and Others”. (shrink)

The fallacies approach to argument evaluation can exacerbate problems it aims to address when it comes to social bias, perpetuating social injustice. A diagnosis that an argument commits a fallacy may flag the irrelevance of stereotypical characterizations to the line of reasoning without directly challenging the stereotypes. This becomes most apparent when personal bias is part of the subject matter under discussion, in ethotic argument, including ad hominem and ad verecundiam, which may be recognized as fallacious (...) without addressing whether the ethotic presumptions are true. Yap (2013; 2015) makes this case for ad hominem and the pragma-dialectical understanding of fallacies, expanded here to show related patterns in some other fallacies, and employing the argument schemes understanding of fallacies. Adding critical questions increases the ways reasoners can dismiss arguments as fallacious, and could include directly addressing bias, but if an argument fails on a different critical question, that may yet allow the bias to pass. The fallacies approach is a form of meta-debate and techniques of meta-debate need to address the ubiquity of social bias, not convey them as specialized problems. The view that the fallacies approach to argument evaluation can provide neutrality is dangerously false. Arguers thus should avoid using fallacies for argument evaluation where social stereotypes or schemas might be involved, especially when the subject matter relates closely to social justice.

“Place” as an argumentative domain, which has been taken for granted and treated by theorists of argumentation simply as a physical notion designating the occasion where an argumentation takes place, carries far more complex meanings beyond its traditionally assumed domain in the following three dimensions: as a geographical locale; as a concept, an idea, a history or a notion with its own disputable narratives and presumptions; and as an imaginative geography. Similarly, an image or a character projected through argumentative discourse (...) should be among the central concerns for argumentation studies, however, limited attention has nevertheless been paid to this traditional face of argument in general and the collective face in particular. We argue that image is a site of discursive production, a symbolic field or a discursively disputable space. The discursive interplay among “place,” “image,” “argument” and “time” offer a new way of thinking about ethotic argument and its key role in the establishment of discursive credibility. (shrink)

Ethotic arguments, such as arguments from expert opinion and ad hominem arguments, play an important role in communication practice. In this paper, we argue that there is another type of reasoning from ethos, in which people argue about actions in the world. These subspecies of ethotic arguments are very common in public debates: societies are involved in heated disputes about what should be done with monuments of historical figures such as Stalin or Colston: Should we demolish the building (...) they funded? Should we revere their statues? Should the street named after them be renamed?; and the general public vividly argue about what should be done with the legacy of producers, directors and actors in debates of the #MeToo movement: Should their new movies be distributed? Should their scenes be deleted from motion pictures? Should their stars from the Hollywood Walk of Fame be removed? Many arguments in these debates boil down to the character of the public figures: He was a slave trader!—But he is a part of our history; He harassed a young girl!—But he is an important actor. The reasoning step here is legitimised by the association between a person and an extra-linguistic object: the association between a historical figure and their statue or between an actor and their movie. The nature of this association is explained in the paper using Peirce’s theory of signs. We propose to extend an existing approach to patterns of reasoning from ethos that will help us to shed new light on ethotic argumentation and open an avenue for a systematic account of these unexplored argument forms.

The aim of the paper is to explore the interrelation between persuasion tactics and properties of speech acts. We investigate two types of arguments ad: ad hominem and ad baculum. We show that with both of these tactics, the structures that play a key role are not inferential, but rather ethotic, i.e., related to the speaker’s character and trust. We use the concepts of illocutionary force and constitutive conditions related to the character or status of the speaker in order (...) to explain the dynamics of these two techniques. In keeping with the research focus of the Polish School of Argumentation, we examine how the pragmatic and rhetorical aspects of the force of ad hominem and ad baculum arguments exploit trust in the speaker’s status to influence the audience’s cognition.

In their book Commitment in Dialogue, Walton and Krabbe claim that formal dialogue systems for conversational argumentation are “not very realistic and not easy to apply”. This difficulty may make argumentation theory less well adapted to be employed to describe or analyse actual argumentation practice. On the other hand, the empirical study of real-life arguments may miss or ignore insights of more than the two millennia of the development of philosophy of language, rhetoric, and argumentation theory. In this paper, we (...) propose a novel methodology for adapting such theories to serve as applicable tools in the study of argumentation phenomena. Our approach is both theoretically-informed and empirically-grounded in large-scale corpus analysis. The area of interest are appeals to ethos, the character of the speaker, building upon Aristotle’s rhetoric. Ethotic techniques are used to influence the hearers through the communication, where speakers might establish, but also emphasise, weaken or undermine their own or others’ credibility and trustworthiness. Specifically, we apply our method to Aristotelian theory of ethos elements which identifies practical wisdom, moral virtue and goodwill as components of speakers’ character, which can be supported or attacked. The challenges we identified in this case and the solutions we proposed allow us to formulate general guidelines of how to exploit rich theoretical frameworks to the analysis of the practice of language use.

This paper outlines an argument for atheism from naturalism that I have developed in more detail elsewhere (in particular, in *The Best Argument against God*). The overall shape of the argument is as follows: first, naturalism is simpler than theism; second, there is no data that naturalism does not explain at least as well as theism; and, third, naturalism entails atheism; so we have good reason to prefer atheism to theism. Note that this statement of the shape (...) of the argument is NOT a statement of the argument itself. (shrink)

The Open Universe is the centerpiece of the argument of the Postscript.

The naïve argument against moral vegetarianism claims that if it is wrong for us to eat meant then it is wrong for lions and tigers to do so as well. I argue that the fact that such carnivores lack higher order mental states and need meat to survive do suffice to undermine the naive argument.

This is a critical discussion of the argument that since intentions are "logically connected" with their objects, Intentional actions cannot include intentions as their causes. Various versions of the argument are discussed, And it is argued that none of them shows the causal theory of intention to be inconsistent. It is argued that the causal theory is nevertheless wrong since intentions must be understood teleologically and as being, Therefore, Non-Contingently linked with actions.

Strong predictivism, the idea that novel predictions per se confirm theories more than accommodations, is based on a “no miracle” argument from novel predictions to the truth of theories (NMAT). Eric Barnes rejects both: he reconstructs the NMAT as seeking an explanation for the entailment relation between a theory and its novel consequences, and argues that it involves a fallacious application of Occam’s razor. However, he accepts a no miracle argument for the truth of background beliefs (NMABB): scientists (...) endorsed a successful theory because they were guided by largely true background beliefs. This in turn raises the probability that the theory is true; so Barnes embraces a form of weak predictivism, according to which predictions are only indirectly relevant to confirmation. To Barnes I reply that we should also explain how the successful theory was constructed, not just endorsed; background beliefs are not enough to explain success, scientific method must also be considered; Barnes can account for some measure of confirmation of our theories, but not for the practical certainty conferred to them by some astonishing predictions; true background beliefs and reliability by themselves cannot explain novel success, the truth of theories is also required. Hence, the NMAT is sound, and strong predictivism is right. In fact, Barnes misinterprets the NMAT, which does not involve Occam’s razor, takes as explanandum the building of a theory which turned out to predict surprising facts, and successfully concludes that the theory is true. This accounts for the practically certain confirmation of our most successful theories, in accordance with strong predictivism. (shrink)

Samuel Rickless presents a new account of Berkeley's controversial argument, and suggests it is the philosopher's greatest legacy: not only is it valid, but it may well be sound.

There is a theistic argument which is discussed at least twice in the Hume corpus, both times rather perfunctorily. This perfunctoriness has carried over to some of his commentators, who are not always clear as to what the argument is or about the force of Hume’s comments on it. On page 23 of A Letter from a Gentleman to his Friend in Edinburgh Hume calls it “the metaphysical Argument a priori” and in Part 9 of Dialogues concerning (...) Natural Religion simply “the argument a priori”.1 It is the argument of Demea. (shrink)

Most anyone interested in such topics as creation mythology, Jungian theory, or the idea of "secret teachings" in ancient Judaism and Christianity has found "gnosticism" compelling. Yet the term "gnosticism," which often connotes a single rebellious movement against the prevailing religions of late antiquity, gives the false impression of a monolithic religious phenomenon. Here Michael Williams challenges the validity of the widely invoked category of ancient "gnosticism" and the ways it has been described. Presenting such famous writings and movements as (...) the Apocryphon of John and Valentinian Christianity, Williams uncovers the similarities and differences among some major traditions widely categorized as gnostic. He provides an eloquent, systematic argument for a more accurate way to discuss these interpretive approaches.The modern construct "gnosticism" is not justified by any ancient self-definition, and many of the most commonly cited religious features that supposedly define gnosticism phenomenologically turn out to be questionable. Exploring the sample sets of "gnostic" teachings, Williams refutes generalizations concerning asceticism and libertinism, attitudes toward the body and the created world, and alleged features of protest, parasitism, and elitism. He sketches a fresh model for understanding ancient innovations on more "mainstream" Judaism and Christianity, a model that is informed by modern research on dynamics in new religious movements and is freed from the false stereotypes from which the category "gnosticism" has been constructed.

Most opposition to abortion stands or falls on whether a fetus is the sort of being whose life it is seriously wrong to end. In her influential paper ‘A defense of abortion,’ Judith Jarvis Thomson effectively sidesteps this issue, assuming the fetus is a person with the right to life yet arguing this alone does not give it the right to use the mother’s body. In a recent article, Perry Hendricks takes inspiration from Thomson and assumes the fetus is not (...) a person, arguing that abortion is wrong because causing fetal impairment is wrong and abortion is worse than causing fetal impairment. Here I argue Hendricks’ impairment argument fails. For Hendricks, risking fetal impairment is wrong because it risks harm to a future person, but if we assume the fetus is not a person, abortion doesn’t harm anyone, it merely prevents them from existing.

This book offers a detailed study of political argument in early eighteenth-century England, a time in which the politics of virtue were vigorously pursued - and just as vigorously challenged. In tracing the emergence of a privately orientated conception of civic virtue from the period's public discourse, this book not only challenges the received notions of the fortunes of virtue in the early modern era but provides a promising critical perspective on the question of what sort of politics of (...) virtue is possible or desirable today.

This paper studies the use of hypothetical and value-based reasoning in US Supreme-Court cases concerning the United States Fourth Amendment. Drawing upon formal AI & Law models of legal argument a semi-formal reconstruction is given of parts of the Carney case, which has been studied previously in AI & law research on case-based reasoning. As part of the reconstruction, a semi-formal proposal is made for extending the formal AI & Law models with forms of metalevel reasoning in several (...) class='Hi'>argument schemes. The result is compared with Rissland’s (1989) analysis in terms of dimensions and Ashley’s (2008) analysis in terms of his process model of legal argument with hypotheticals. (shrink)

Several philosophers of science and metaphysicians claim that the dispositional properties of fundamental particles, such as the mass, charge, and spin of electrons, are ungrounded in any further properties. It is assumed by those making this argument that such properties are intrinsic, and thus if they are grounded at all they must be grounded intrinsically. However, this paper advances an argument, with one empirical premise and one metaphysical premise, for the claim that mass is extrinsically grounded and is (...) thus an extrinsic disposition. Although the argument concerns mass characterized as a disposition, it applies equally well whether mass is a categorical or dispositional property; however, the dispositional nature of mass is relevant to some important objections and implications discussed.
