The detection of hate speech and fake news in political discourse is at the same time a crucial necessity for democratic societies and a challenge for several areas of study. However, most of the studies have focused on what is explicitly stated: false article information, language that expresses hatred, derogatory expressions. This paper argues that the explicit dimension of manipulation is only one – and the least problematic – of the risks of political discourse. The language of the unsaid is (...) much more dangerous and incomparably more difficult to detect, hidden in different types of fallacies and inappropriate uses of emotive language. Through a threefold coding scheme based on the instruments of argumentation theory and pragmatics, a corpus of argumentative tweets published by 4 politicians (Matteo Salvini, Donald Trump, Jair Bolsonaro, and Joseph Biden) within 6 months from their taking office (corresponding to the official end of their election campaign) is analyzed, detecting the types of argument, the fallacies, and the uses and misuses of “emotive words.” This coding results in the argumentation profiles of the speakers, which are compared statistically to show their different implicit strategies and deceptive tactics.

The phenomenon of presupposition suspension can be analyzed in terms of explicatures and the corresponding non-presumptive interpretative reasoning underlying it. On the view presented in this paper, the polyphonic articulation of an utterance at different levels can be used to explain cases in which presuppositions are suspended. Presuppositional suspensions indicate that the presumptive reading does not hold and a different interpretation is needed. Utterances can display various types of polyphonic structures, accounting for the speaker’s and the hearer’s commitments. A speaker (...) can be held directly responsible for what he says, but he is committed only indirectly to what he presupposes, i.e. what is uttered by a second voice (the second utterer or enunciator) representing what the common opinion accepts to be true. The reconstruction of the pragmatic structure of an utterance is guided by a complex type of reasoning, which can be represented as an argumentative abductive pattern, grounded on hierarchies of presumptions. By comparing the possible presumptions associated with the explicit meaning and the contextual information, the hearer can find a best possible explanation of the intended effect of the utterance.

Pragmatic presuppositions are analyzed considering their relation with the notion of commitment, namely the dialogical acceptance of a proposition by an interlocutor. The attribution of commitments carried out by means of pragmatic presupposition is shown to depend on the reasonableness of the underlying presumptive reasoning, ultimately grounded on hierarchies of presumptions. On this perspective, the ordinary interpretation of pragmatic presuppositions as the “taking for granted” of propositions signaled by semantic or syntactic triggers becomes only the presumptive, prototypical interpretation of a (...) complex linguistic and pragmatic phenomenon. It will be shown how the prototypical interpretation is subject to default in cases of conflicts of presumptions, which lead to reconstructing the speaker’s meaning non-presumptively at a pragmatic, semantic, or syntactic level. The phenomena of presupposition cancellation and neutralization can be explained in terms of presumptive and non-presumptive articulation and interpretation of an utterance, through which the speaker can impose, correct, or refuse implicit commitments.

Pragmatic presupposition is analyzed in this paper as grounded on an implicit reasoning process based on a set of presumptions, which can define cultural differences. The basic condition for making a presupposition can be represented as a reasoning criterion, namely reasonableness. Presuppositions, on this view, need to be reasonable, namely as the conclusion of an underlying presumptive reasoning that does not or may not contain contradictions with other presumptions, including the ordering of the hierarchy of presumptions. Presumptions are in turn (...) analyzed considering their nature and their hierarchy, namely their object and their possible contextual backing, which eliminates some of their possible defaults. This analysis of presupposition brings to light the relationship between communicative infelicities or misunderstandings deriving from presuppositional failures and the underlying system of presumptions and presumptive reasoning. This approach can be applied to the investigation of communicative problems within the medical context, and more precisely the communication in diabetes cases. (shrink)

The analysis of multimodal argumentation in advertising is a crucial and problematic area of research. While its importance is growing in a time characterized by images and pictorial messages, the methods used for interpreting and reconstructing the structure of arguments expressed through verbal and visual means capture only isolated dimensions of this complex phenomenon. This paper intends to propose and illustrate a methodology for the reconstruction and analysis of “double-mode” arguments in advertisements, combining the instruments developed in social semiotics, pragmatics, (...) and argumentation theory. An advertisement is processed through a five-step path. The analysis of its context, text genre, and images leads to a first representation of the messages that it encodes both pictorially and verbally (step 1). These first semantic representations are further enriched by including their polyphonic articulations and presuppositions (step 2), their explicatures (step 3), and their dialogical functions and illocutionary forces (step 4). These pragmatic steps retrieve the commitment structure of the ad, which allows a further argument analysis conducted through argumentation schemes (step 5). (shrink)

The purpose of this paper is to show how micro-argumentation mechanisms of presumptive reasoning and reasoning from best explanation can be used for explaining some cases of presupposition cancellation. It will be shown how the relationship between presupposition triggers and pragmatic presuppositions can be analyzed in terms of presumptive and non-presumptive polyphonic articulation of an utterance, resulting in different types of commitments for the interlocutors. This approach is grounded on the two interconnected notions of presumptions and commitments. In some complex (...) cases of presupposition “suspension,” the speaker presumes the hearer’s acceptance of and commitment to propositions that cannot be presumed as such, namely that do not belong to the common ground, or that have been explicitly rejected as being commonly shared. This phenomenon triggers a complex type of reasoning that can be represented as an abductive pattern, grounded on hierarchies of presumptions and aimed at providing an interpretation that solves this conflict of presumptions. Several cases of suspension of presupposition will be investigated as resulting from non-presumptive polyphonic articulations, in which different voices responsible for distinct commitments are distinguished. By indirectly reporting an element of discourse, the speaker can refuse to take responsibility for the presupposed proposition, and correct the commitments that may result for him. This polyphonic treatment of utterances shows how and why a presupposition is suspended, and identifies the conflicting presumptions that can be further solved through reasoning from best explanation. This reasoning can result in a different reconstruction of the developed logical form of utterance or of its illocutionary force. (shrink)

Traditional definitions of common ground in terms of iterative de re attitudes do not apply to conversations where at least one conversational participant is not acquainted with the other(s). I propose and compare two potential refinements of traditional definitions based on Abelard’s distinction between generality in sensu composito and in sensu diviso.

Affective polarization is characterized by deep antagonism between political opponents and is an issue of growing concern. Some philosophers have recently suggested empathy as a possible remedy. In particular, it has been suggested that empathy might mitigate the harm resulting from affective polarization by helping us find common ground across our differences. While these discussions provide a helpful starting point, important questions regarding the conditions under which empathizing and finding common ground are morally appropriate and likely to be useful, given (...) the many risks associated with taking this approach, remain unaddressed. In this paper, I therefore give an account of the risks that we must reckon with if empathy and common ground are to help remedy affective polarization and repair damaged relations between political opponents. Far from suggesting that empathy is morally unimportant or intrinsically harmful, my goal is thus to extend and amplify previous discussion to promote a more nuanced understanding of empathy's role in this important aspect of the moral life and to ensure that our efforts to empathize are appropriate and fruitful.
