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.

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.

Building on our diverse research traditions in the study of reasoning, language and communication, the Polish School of Argumentation integrates various disciplines and institutions across Poland in which scholars are dedicated to understanding the phenomenon of the force of argument. Our primary goal is to craft a methodological programme and establish organisational infrastructure: this is the first key step in facilitating and fostering our research movement, which joins people with a common research focus, complementary skills and an enthusiasm to work (...) together. This statement—the Manifesto—lays the foundations for the research programme of the Polish School of Argumentation. (shrink)

Pragmatics and dialectics are two disciplines which have been amongst the first and most important partners for argument studies in the exploration of the complex realm of communication. Treating argumentation as a construct consisting of premises and conclusion allows for investigating some interesting properties of the phenomenon of reasoning, but does not capture a variety of aspects related to the usage of natural language and dialogical context in which real-life argumentation is typically embedded. This special issue explores some of the (...) fascinating research questions which emerge when we move beyond logic into the territory of the pragmatics and dialectics of argument. (shrink)

This work presents a requirement analysis for collaborative dialogues among medical experts and an inquiry dialogue game based on this analysis for incorporating explainability into multiagent system design. The game allows experts with different knowledge bases to collaboratively make recommendations while generating rich traces of the reasoning process through combining explanation-based illocutionary forces in an inquiry dialogue. The dialogue game was implemented as a prototype web-application and evaluated against the specification through a formative user study. The user study confirms that (...) the dialogue game meets the needs for collaboration among medical experts. It also provides insights on the real-life value of dialogue-based communication tools for the medical community. (shrink)

Contemporary argument studies in Poland began with the research of the Lvov-Warsaw School and its successors in Artificial Intelligence and legal theory, as well as with the studies of Polish rhetoricians . The last decade has witnessed a major transformation in the Polish landscape, beginning with several landmark publications which have attracted an ever-growing number of young researchers and students. As a result, the research movement of the Polish School of Argumentation has begun to emerge .In 2008, the nationwide initiative (...) ArgDiaP was established in order to provide infrastructure facilitating the networking process and to foster res .. (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 propose a framework for the structure of persuasive communica-tion based on the Elaboration Likelihood Model by Petty and Cacioppo, the Inference Anchoring Theory by Budzynska and Reed and the Interpersonal Argumentation Model by Budzynska. The ELM suggests that there are two routes to persuasion: central and peripheral. IAT assumes that com-munication acts generate their contents and inferences by means of illocutionary connections. The model of IP-argumentation provides the general representation of arguments (...) in which the proponent refers to com-munication acts of some participant of communication. The paper discusses where exactly means of the central and peripheral routes operate in the structure of persuasive communication and argumentation. (shrink)

The objective of this paper is to show how methods rooted in formal logic may be used to analyze socially important processes of persuasion. A formal approach to the theory of persuasion enables us to thoroughly research issues crucial in everyday life such as: how we argue, why we quarrel, where we are efficient in persuasion, when do we win a negotiation, how we influence others’ decisions, and the kinds of argumentative strategies that are apt to yield more accurate beliefs (...) for all parties involved.I concentrate on three aspects of persuasion practice: nature, success and cognitive value of argumentation process. From a logical perspective, I understand argumentation as reasoning which, after initiation through the opponent’s disagreement, is deployed by the proponent in order to persuade the audience to believe his thesis. Furthermore, I attempt to determine the ways in which we succeed in persuading others. Lastly, I try to specify when an argument is cognitively valuable and when it is reliable, in the sense that it helps us to track the truth. In order to analyze these matters, I investigate argumentation on two independent levels. The subjective level of people’s beliefs is the essential foundation of all persuasion -- every time we aim to make the audience believe our opinions and /or change their decisions. The second level is the objective field of truthfulness, where we consider whether a given argumentation will lead us to true or false conclusions. (shrink)

In the paper I want to give a new account of notions of reasoning, argumentation, and persuasion. The aim of it is to resolve problems of the traditional accounts. The investigation uses the issue of circular reasoning. These types of arguments are considered a fallacy in informal logic, whereas formal logic holds that they are valid. The new account suggests a possibility of reconciliation of the informal and formal perspective.

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.

Explainable artificial intelligence has become a vitally important research field aiming, among other tasks, to justify predictions made by intelligent classifiers automatically learned from data. Importantly, efficiency of automated explanations may be undermined if the end user does not have sufficient domain knowledge or lacks information about the data used for training. To address the issue of effective explanation communication, we propose a novel information-seeking explanatory dialogue game following the most recent requirements to automatically generated explanations. Further, we generalise our (...) dialogue model in form of an explanatory dialogue grammar which makes it applicable to interpretable rule-based classifiers that are enhanced with the capability to provide textual explanations. Finally, we carry out an exploratory user study to validate the corresponding dialogue protocol and analyse the experimental results using insights from process mining and argument analytics. A high number of requests for alternative explanations testifies the need for ensuring diversity in the context of automated explanations. (shrink)

Expertise, authority, and testimony refer to aspects of one of the most important elements of communication and cognition. Argumentation theory recognises various forms of what we call the argumentum ad alia pattern, in which speakers appeal to what others have said, including Position to Know scheme, Witness Testimony scheme, Expert Opinion scheme and the classical ad verecundiam. In this paper we show that ad alia involves more than merely an inferential step from what others (a person in position to know, (...) a witness, an expert) have said, and that studying this type of argumentation requires going beyond the argument structure of propositional contents to account for different speech activities. We also demonstrate that using the words of others, attacking what has been said, and reasoning from how others reason constitute a rich repertoire of communication strategies which we need to model in order to be able to analyse them manually and to process them computationally.

In theory, flawed arguments are not individually sufficient to justify a conclusion, but several may converge to do so. This is an empirical study of how arguers respond to a series of imperfect causal arguments during a serious conversation. People became less critical of the flawed arguments as more of the arguments appeared. The study gives empirical evidence that ordinary arguers permit sufficiency to accumulate during an extended discussion.

In September 2018, the ArgDiaP association, along with colleagues from Germany and the UK, organised one of the longest and most interdisciplinary series of events ever dedicated to argumentation - Warsaw Argumentation Week, WAW 2018. The eleven-day ‘week’ featured a five day graduate school on computational and linguistic perspectives on argumentation (3rd SSA school); five workshops: on systems and algorithms for formal argumentation (2nd SAFA), argumentation in relation to society (1st ArgSoc), philosophical approaches to argumentation (1st ArgPhil), legal argumentation (2ndMET-ARG) (...) and argumentation in rhetoric (1st MET-RhET); and two conferences: on computational models of argumentation (7th COMMA conference) and on argumentation and corpus linguistics (16th ArgDiaP conference). WAW hosted twelve tutorials and eight invited talks as well as welcoming over 130 participants. All the conferences and workshops publish pre- or post-proceedings in the top journals and book series in the field. (shrink)

The Argument Web is maturing as both a platform built upon a synthesis of many contemporary theories of argumentation in philosophy and also as an ecosystem in which various applications and application components are contributed by different research groups around the world. It already hosts the largest publicly accessible corpora of argumentation and has the largest number of interoperable and cross compatible tools for the analysis, navigation and evaluation of arguments across a broad range of domains, languages and activity types. (...) Such interoperability is key in allowing innovative combinations of tool and data reuse that can further catalyse the development of the field of computational argumentation. The aim of this paper is to summarise the key foundations, the recent advances and the goals of the Argument Web, with a particular focus on demonstrating the relevance to, and roots in, philosophical argumentation theory.

In the spirit of the pragmatic account of quotation and reporting offered by Macagno and Walton (2017), we outline a systematic pragmatic account of rephrasing. For this purpose, we combine two interrelated methods of inquiry into the variety of uses of rephrase as a persuasive device: (i) the annotation of rephrase types to identify locutionary and illocutionary aspects of rephrase, (ii) the crowd–sourced examination of rephrase types to investigate their perlocutionary effects. As it draws on Waltonian insights and on empirical (...) and experimental research on the (mis)use of rephrase, our approach allows us to ground a novel theoretically–informed and data–driven pragmatic account of rephrase.

It is widely accepted that the machinery of multicultural societies and liberal democratic systems is dependent upon various forms of dialogue - dialogue between political parties, between different social groups, between the ruling and the ruled. But what are the conditions of a democratic dialogue and how does the philosophical dialogic approach apply to practice? Exploring the multifaceted nature of the concepts of dialogue and democracy, and critically examining materializations of dialogue in social life, this book offers a variety of (...) perspectives on the theoretical and empirical interface between democracy and dialogue.

In this paper the authors address the issue of investments made by family businesses. Their study attempted to verify the level of investments made by Polish family businesses in comparison with the level of investments made by Polish non-family businesses. The study focused on the analysis of investment flows of Polish listed companies included in the WIG index for the years 2006-2018. A total of 233 companies were analyzed, including 177 non-family businesses and 56 family businesses. The results corroborated the (...) argument that Polish listed non-family businesses invest much more money than family businesses. It was also observed that only a small percentage of companies in both groups invest their finances in research and development. (shrink)

We show that a finitely generated protoalgebraic strict universal Horn class that is filter-distributive is finitely based. Equivalently, every protoalgebraic and filter-distributive multidimensional deductive system determined by a finite set of finite matrices can be presented by finitely many axioms and rules.

The research concerned the determinants of social competencies, which are significant indicators of the quality of interpersonal relations. The aim of the study was to verify the connection between social competencies and temperamental traits. The respondent group included 220 university students of different faculties aged 19-24. Social competencies were measured with the use of a Social Competencies Questionnaire by Anna Matczak, while temperamental traits were measured with The Formal Characteristics of Behaviour-Temperament Inventory, by Bogdan Zawadzki and Jan Strelau. The research (...) proved that activity, emotional reactivity and sensory sensitivity are significant predictors of social competencies. The predictive value of these traits differs depending on the kind of measured competency. (shrink)

This paper is devoted to clarifying Hannah Arendt’s concept of political freedom by the means of analysing its structure. My analysis proceeds in three steps. Firstly, I distinguish a pre-political concept of freedom as exercising spontaneity, which is at the root of Arendt’s understanding of political freedom. Secondly, I analyse her account of freedom as exercising action and indicate its relationship to the elementary freedom of spontaneity. Arendt endowed action with a distinguished importance, since she assumed that it is the (...) only activity within the vita activa, which has a special anthropological and axiological significance. According to Arendt, only action allows one to truly experience the fundamental aspect of the human condition, which is the fact of human plurality; it is also the only activity which allows one to exercise specifically public principles, such as solidarity, equality, or justice. Thirdly, I indicate how these two accounts of freedom translate into Arendt’s concept of political freedom. This analysis reveals that the Arendtian concept of political freedom is markedly original. She did not define it in a usual manner, i.e. through indicating bundles of legal and political rights which determine the accepted scope of participation in the public affairs. The inherent part of her concept of political freedom is a specific account of how it must be exercised. Political freedom understood as the participation in governance exercised through action is not merely an activity of instrumental, but also anthropological and axiological importance, which is due to the special anthropological and axiological meaning of action. In the final section, I discuss the practical dimension of Arendt’s theory. She doubted whether the traditional representative democracy is capable of accommodating her ‘rich’ ideal of political freedom, therefore she proposed an alternative account of political system based on councils. I formulate objections against this proposition and demonstrate that councils would presumably fail to accommodate Arendt’s exacting account of political freedom. (shrink)

The Uppsala School in philosophy and the Vienna Circle are prima facie similar currents in contemporary philosophy. Both reject metaphysics, claim that reality is a spatio­‑temporal realm and adhere to noncognitivism in terms of values. However, justifications of these assumptions are quite different. In the following article we reconstruct main theses of both mentioned currents and then we indicate their impact on one of the major jurisprudential movements, namely Scandinavian Legal Realism. We focus on Alf Ross’ legal philosophy, as it (...) was an attempt to accommodate both: the philosophy of the Uppsala School and of the Vienna Circle. We trace those two sources of inspiration in Ross’ theory of legal validity and of legal concepts. (shrink)

Frankfurt-style examples aim to undermine the principle that moral responsibility requires the ability to do otherwise, which in turn requires the availability of alternate possibilities.1 They are thus considered a reason for refuting incompatibilism. One lesson drawn from Frankfurt-style examples is exemplified by the compatibilist account of Fischer and Ravizza.2 They accept the impact of Frankfurt-style cases and hold that the incompatibilist requirement of regulative control, which involves the agent’s ability to perform the action and her ability to perform the (...) contrary action, must be dropped. In its stead, they propose the weaker requirement of guidance control, which only demands the agent’s causal control over the action for which she is to be held responsible. (shrink)

The paper focuses on the issue of truth-telling in non-fictional narratives of (in)justice. Based on examples of rape narratives, domestic abuse narratives, human trafficking narratives and asylum seeker narratives, I examine the various difficulties in telling the truth in such stories, particularly those related to various culturally conditioned ideas of how the world works, which at the same time form the basis of, among other things, legal discourse and officials’ decision-making processes. I will also demonstrate that such culturally conditioned ideas, (...) which are the basis of official discourse, can be considered within the category of both the social imaginary of the just world in the Taylorian sense of the term, and the social master narrative, which in the case of stories of (in)justice is often based on the just world hypothesis.

This book is about beliefs, language, communication and cognition. It deals with the fundamental issue of the interpretation of the speaker's utterance expressing a belief and reporting on beliefs of other people in the form of oratio obliqua. The main aim of the book is to present a new account of the problem of interpreting utterances expressing beliefs and belief reports in terms of an approach called Default Semantics.
