The Covid-19 pandemic has affected not only the health of populations but also their everyday social practices, transformed by orienting to risks of contagion and to health prevention discourses. This paper emanates from a project investigating the impact of Covid-19 on human sociality and more particularly the situated and embodied organization of social interactions. It discusses how Covid-19 impacts the design of ordinary actions in social interaction, how this is made publicly accountable by the participants orienting to the pandemic in (...) formatting their actions and in responding to the actions of others. Adopting an ethnomethodological and conversation analytic perspective, the analyses focus on a particular social activity: paying. The organization of payments in shops and services has been affected by the pandemic, not only by official regulations, favoring some modes of payment over others, but also in how sellers and customers situatedly adapt their practices to imperatives of prevention. On the basis of a rich corpus of video-recorded data, which spans from the pandemic’s prodromes to and after its peak, we show how money transfer is methodically achieved – imposed, negotiated, and readjusted – while variously taking into account possible risks of contagion. Thus, we show not only how pandemics affect social interaction, and how prevention is incarnated in social actions, but also how, in turn, situated solutions implemented by people during the pandemic reveal fundamental features of human action.

This paper focusses on colour terminology as a tool for achieving ἐνάργεια in the Latin poetry of the first century c.e. After briefly outlining the developments in the concept of ἐνάργεια from Aristotle to Quintilian, the paper considers the use of Latin terms for black in three descriptive passages from Statius’ epic poem, the Thebaid. It is observed that the poet privileges the juxtaposition of the two adjectives ater and niger in a pattern of uariatio, where ater often carries a (...) figurative meaning and repeats established poetic clichés, while niger is part of unparalleled collocations that evoke a material notion of blackness. Further analysis of the uariatio in the context of each passage reveals that the juxtaposition of the two-colour terms enhances the vividness of the objects described not only by increasing their chromatic impact but also by establishing connections with other parts of the poem, and by inviting a reflection on the competing practices of imitation and transgression of poetic models. The analysis of one stylistic feature shows that this stylistic feature is used by Statius for achieving ἐνάργεια as an artistic effect, for reflecting on ἐνάργεια as an instrument through which poetic models are challenged, and for tying his own poetic practice to contemporary rhetorical discussions.

The article investigates a multimodal practice for self-selecting observed in a video-taped corpus of work meetings: the use of pointing gestures predicting possible turn completions and projecting the emergence of possible next speakers. This practice is analyzed in various sequential positions, namely at turn beginnings and at pre-beginnings. It displays recipients' practical online turn parsing, and their orientation to transition spaces, and to TCU, completions in a visible, recognizable, public way. It shows the emergent and progressive establishment of speakership, exploiting (...) both systematic features of turn-taking and specific features of the interactional space. The article explores the emic, locally situated and contingent definition of speakership by considering not only where pointing gestures begin but also where they end: pointing does not only end in pre-completion positions, projecting turn end, but can also persist through sequences, showing speaker's orientations to her turn's sequential implicativeness. Thus, by observing a particular multimodal practice within a specific interactional setting, the article explores participants' orientations to the rights and obligations associated with talk-related categories such as `non current speaker', `possible next speaker', `incipient speaker' and `current speaker'.

This article contributes to ongoing studies in conversation analysis dealing with the way in which epistemic authority is displayed, claimed, contested and negotiated in social interaction. More particularly, it focuses on the articulation between action format, sequential organization, membership categorization and epistemic authority. The article offers an empirical analysis of the way in which knowledge is distributed and recognized in social gatherings, with a special focus on guided visits. Guided visits are a perspicuous setting for this analysis, since it is (...) an activity in which the guide displays knowledge in comments and explanations and the guided seeks for knowledge in questions. However, this distribution of knowledge is regularly challenged. The article offers a systematic study of a collection of sequences initiated by turns beginning with ‘et là’ and locating a new referent in the environment, either in informings or in questions. While the former are frequently produced by the guide, assuming a knowing status, and the latter by the guided, assuming a not knowing, it is possible to observe informings initiated by the guided, who, by so doing, claims a revision of his or her epistemic authority. Likewise, in second position, questions are generally answered by the guide, but can also be answered by another person, claiming alternative epistemic rights. By examining the details of turn and action design in these environments, the article shows how they either reproduce and confirm the current epistemic status of the participants or challenge, negotiate and transform them. The latter case is particularly revealing of the fact that epistemic status and stance are constantly reflexively elaborated by the participants in social interaction. (shrink)

The article analyses the chapter on dreams of the Specchio di vera penitenza by Iacopo Passavanti, a Dominican friar who lived in 14th century Florence, focusing on the philosophical sources employed by the preacher. This section of the Specchio is in fact peculiar, since Iacopo discusses here the value of dreams for human knowledge by means of Aristotelian concepts and doctrines, but it does not mention them explicitly. Moreover, while discussing on dreams, Iacopo lingers on the myth of the magnetic (...) mountain following the pseudo-Aristotelian De lapidibus and the treatise On Minerals by Albert the Great. The article studies also Passavanti’s other sources concerning this passage, such as the De lapidibus by Marbodus of Rennes and the Speculum historiale by Vincent of Beauvais. (shrink)

Taste is a central sense for humans and animals, and it has been largely studied either from physiological and neurological approaches or from socio-cultural ones. This paper adopts another view, focused on the activity of tasting rather than on the sense of taste, approached within the perspective of ethnomethodology and multimodal conversation analysis. This view addresses the activity of tasting as it is interactionally organized in specific social settings, observed in a naturalistic way, on the basis of video recordings. Focusing (...) on video recorded improvised tastings of cheese in gourmet shop encounters, the paper offers a systematic analysis of the way in which tasting is orderly achieved in an intersubjective way. It follows the various steps characterizing tasting, from the invitation to taste, to the grasping of a bit to taste, which is put in the mouth, chewed, and swallowed; it details how an interactional moment offering the taster a priviledged, individual, focused space in which to devote exclusive attention to the object tasted is actively tailored by all parties. By contrast, the completion of tasting is marked by a return to mutual gaze, the animation of facial expressions and nods, and the final production of a judgment of taste. By offering a systematic reconstruction of how these tasting moments are organized, the paper invites to a multimodal approach of sensoriality in social interaction. (shrink)

This article deals with surgical practice as it is locally organized within the course of the operation; it focuses on the way in which surgical action shaping the body for the local purposes of the operation is organized in a timely, situated, interactive manner. In order to do that, I offer a systematic analysis of the instructions addressed by a chief surgeon to his assistant in the form of directives during a surgical operation, as well as of instructed actions of (...) the assistant following the directives of the surgeon. In this way, I aim to show how surgery is a methodic collaborative achievement, relying on finely tuned coordination between staff members. More generally, the article sketches a systematic and detailed analysis of instructions as situated accomplishments in time, and of instructed action as resulting from an embodied and indexical understanding of directives and requests as they are produced in time and in context.

Aristocles of Messene is a first century AD Aristotelian philosopher who discusses the thought of ancient Greek philosophers, including Plato, Zeno, Pyrrho, and Epicurus, as well as Eleatic and Cyrenaic philosophies. His main contribution is his testimony on Pyrrhonism, and his political verve makes his On Philosophy an interesting and amusing read for specialists and non-specialists alike.

Buddhism has captured the imagination of many in the modern (Western) world. Recently, scientists have seemed eager to discover whether claims about Buddhist meditation can be verified experimentally. Brain research is beginning to produce concrete evidence that mental discipline and meditative practice can change the workings of the brain and allow practitioners to achieve different levels of awareness, as measurable for instance in reaction times to stimuli. The goal of this section of articles in Zygon is to address recent developments (...) in this area. The contributions address a wide array of questions, although they certainly do not cover the whole ground of what one may consider “problems” of meditation. Yet, we believe that the issues addressed here have widespread implications and that they constitute a strong argument for the richness of the meditation domain. (shrink)

What I call theoretical abduction (sentential and model-based) certainly illustrates much of what is important in abductive reasoning, especially the objective of selecting and creating a set of hypotheses that are able to dispense good (preferred) explanations of data, but fails to account for many cases of explanations occurring in science or in everyday reasoning when the exploitation of the environment is crucial. The concept of manipulative abduction is devoted to capture the role of action in many interesting situations: action (...) provides otherwise unavailable information that enables the agent to solve problems by starting and performing a suitable abductive process of generation or selection of hypotheses. Many external things, usually inert from the epistemological point of view, can be transformed into what I call epistemic mediators, which are illustrated in the last part of the paper, together with an analysis of the related notion of external representation . Finally, some examples of computational programs that simulate geometrical reasoning are illustrated. The computational embodiment generates a kind of squared epistemic mediator: geometrical construction, as an example of epistemic mediator, is further mediated. (shrink)

Cognitive niche theories consist in a theoretical framework that is proving extremely profitable in bridging evolutionary biology, philosophy, cognitive science, and anthropology by offering an inter-disciplinary ground, laden with novel approaches and debates. At the same time, cognitive niche theories are multiple, and differently related to niche theories in theoretical and evolutionary biology. The aim of this paper is to clarify the theoretical and epistemological relationships between cognitive and ecological niche theories. Also, by adopting a constructionist approach we will try (...) to explain the shift from ecological to cognitive niches and their actual and theoretical overlaps. In order to do so, we will take two concepts expressing loose forms of causation in the interaction between organisms and their environment: the biological notion of “enablement” and the psycho-cognitive one of “affordance”.

In this paper, I deal with video data not as a transparent window on social interaction but as a situated product of video practices. This perspective invites an analysis of the practices of video-making, considering them as having a configuring impact on both on the way in which social interaction is documented and the way in which it is locally interpreted by video-makers. These situated interpretations and online analyses reflexively shape not only the record they produce but also the interactional (...) order itself as it is documented. Dealing with practices of video-making not as a resource but as a topic, I explore a particular editing practice, the use of the split-screen technique, consisting in combining various camera views within the same image. This technique is now widely used in cinema, professional settings, TV, and social research. I focus on its uses in TV talk shows and debates: through a systematic sequential analysis of the positions where split screen is introduced, I show that directors do orient to the sequential features of interaction in using this technique and that, conversely, their uses of split screen reveal their local understanding—and configuring—of what the interactional dimension of debates and interviews consist of, for all practical purposes.

Each time we take a turn in conversation we indicate what we know and what we think others know. However, knowledge is neither static nor absolute. It is shaped by those we interact with and governed by social norms - we monitor one another for whether we are fulfilling our rights and responsibilities with respect to knowledge, and for who has relatively more rights to assert knowledge over some state of affairs. This book brings together an international team of leading (...) linguists, sociologists and anthropologists working across a range of European and Asian languages to document some of the ways in which speakers manage the moral domain of knowledge in conversation. The volume demonstrates that if we are to understand how speakers manage issues of agreement, affiliation and alignment - something clearly at the heart of human sociality - we must understand the social norms surrounding epistemic access, primacy and responsibilities.

Studies of talk-and-bodily-conduct-in-interaction have inspired new insights into the way in which language, interaction and cognition might be articulated. More particularly, they have shown that participants mutually orient to the finely tuned multimodal details by which talk and action in interaction are sequentially organized. This article deals with this form of ‘participants’ multimodal online analysis’ by focusing on a particular phenomenon - the methodical practices and resources by which the end of a turn and of an activity phase is projected (...) and collectively achieved - in a specific videorecorded setting - a meeting in an architect’s office. It aims at questioning both how these local orientations are systematically displayed and exploited by the participants for the sequential organization of their activity and how they can be demonstrably observed by the analyst.

In this paper we aim at discussing cognitive and epistemic features of online communities, by the use of cognitive niche constructions theories, presenting them as virtual cognitive niches. Virtual cognitive niches can be considered as digitally-encoded collaborative distributions of diverse types of information into an environment performed by agents to aid thinking and reasoning about some target domain. Discussing this definition, we will also consider how online communities, as networks displaying a social bias, can both foster civic awareness and promote (...) problematic group-led behaviors in the virtually aggregated crowds. To support this affirmation, we will take into account the use of online communication networks during crises and we will argue that it can lead to ethically dubious consequences. (shrink)

In this commentary, I consider variability as an ordinary and irremediable feature related to the indexicality not only of transcripts but first of all of transcribing. In this sense, it is not just a characteristic of transcripts as texts, which can be assessed in a kind of philological comparison comparing formal features of autonomous and fixed textual objects, but a characteristic of transcribing as a situated practice. Practices are irremediably indexical, reflexively tied to the context of their production and to (...) the practical purposes of their accomplishment. Thus, a transcript is an evolving flexible object; it changes as the transcriber engages in listening and looking again at the tape, endlessly checking, revising, reformatting it. Transcribing relies in a fundamental way not only on the possibility of fixing the relevant details in a complex multilayered representation but also on the possibility of manipulating them, playing them again and again, at different paces, positions, fragments, while transcribing their finely tuned coordination, their synchronization, the fine articulation between different projections and sequential implicativenesses. These manipulations are one of the ways in which transcribing is accomplished as a situated practice. (shrink)

The interactional organization of meetings is an important locus of observation for understanding the way in which institutions are talked into being. This article contributes to this growing body of research by focusing on turn-taking and participation in business meetings, approached within conversation analysis in a sequential and multimodal way. On the basis of a corpus of video-recorded corporate meetings of a multinational company, in which managers coming from several European branches convene, the article takes into consideration the embodied orientations (...) of the participants as they address each other, as they turn to particular addressees or groups in a recipient designed way while describing, informing, announcing events and results, and as they make relevant specific participants’ identities – especially national categories – and, in this way, display specific local expectations regarding rights and obligations to talk and to know.

In this paper, we aim at explaining the relevance of thought experiments in philosophy and the history of science by describing them as particular instances of two categories of creative thinking: metaphorical reasoning and abductive cognition. As a result of this definition, we will claim that TEs hold an ignorance-preserving trait that is evidenced in both TEs inferential structure and in the process of scenario creation they presuppose. Elaborating this thesis will allow us to explain the wonder that philosophers of (...) science have consistently shown for TEs, as well as the high functionality of TEs in the creative aspects of scientific and philosophical praxis.

O presente artigo analisa a relação que ocorre entre as duas potências superiores da alma - intelecto e vontade - no momento em que se realiza uma qualquer acção, seja positiva ou negativa. Seguindo a análise que S. Tomás de Aquino faz nas Quaestiones disputatae de maio, o artigo mostra o interesse e a profundidade do tratamento que o Aquinate dá à questão, passando em revista, particularmente nas questões 3, 4 e 6, todos os elementos que contribuem para a realização (...) de um acto e evidenciando, nomeadamente de modo diferente a como o faz na Summa theologiae, o papel específico da vontade. /// The article examines the link between the higher powers of the soul (intellect and will) in the process of making an action, being it positive or negative. The author shows the special interest and profundity of Aquinas's analysis in the Quaestiones disputatae de malo (especially qq.

In this paper we show how some reasoning, though fallacious, can appear to be attractive and useful for beings-like-us. Although they do not provide conclusive evidence to support or reject a certain claim the way scientific statements do, they tell us something interesting about how humans build up their arguments and reasons. First of all, we will consider and investigate three main types of fallacies: argumentum ad hominem, argumentum ad verecundiam, and argumentum ad populum. These three fallacies are traditionally considered (...) as examples of a broader category called ignoratio elenchi. Secondly, we show how people who commit these fallacies rely on information about other human beings in their reasoning. That is, they do not follow certain logical procedures that eventually lead them to correct conclusions. But they simply make use of others as social characters. For example, being an authority, being an expert, being part of a class, etc., become the substitutes for more direct evidence to support a certain claim or to make an argument more appealing.

Gossip has been the object of a number of different studies in the past 50 years, rehabilitating it not only as something worth being studied, but also as a pivotal informational and social structure of human cognition: Dunbar (Rev Gen Psychol 8(2):100–110, 2004) interestingly linked the emergence of language to nothing less than its ability to afford gossip. Different facets of gossip were analyzed by anthropologists, linguists, psychologists and philosophers, but few attempts were made to frame gossip within an epistemological (...) framework (for instance Ayim in (Good gossip, pp. 85–99, 1994)). Our intention in this paper is to provide a consistent epistemological (applied and social) account of gossip, understood as broadly evaluative talk between two or more people, comfortably acquainted between each other, about an absent third party they are both at least acquainted with. Hence, relying on the most recent multidisciplinary literature about the topic, the first part of this paper will concern the epistemic dynamics of gossip: whereas the sociobiological tradition individuates in gossip the clue for the (theoretically cumbersome) group mind and group-level adaptations Wilson et al. (The evolution of cognition, pp. 347–365, 2002), we will suggest the more parsimonious modeling of gossip as a soft-assembled epistemic synergy, understood as a function-dominant interaction able to project a higher organizational level—in our case, the group as group-of-gossips. We will argue that the aim of this synergy is indeed to update a Knowledge Base of social information between the group (as a projected whole) and its members. The second and third part will instead focus on the epistemological labeling of the inferences characterizing gossip: our contention is that the ever-present moral/evaluative dimension in gossip—be it tacit or explicit, concerning the objects or the partners of gossip—is best analyzed through the epistemological framework of abduction. Consequently, we will suggest that a significant role of gossip is to function as a group-based abductive appraisal of social matter, enacted at various levels. (shrink)

Embedding ethics modules within computer science courses has become a popular response to the growing recognition that CS programs need to better equip their students to navigate the ethical dimensions of computing technologies like AI, machine learning, and big data analytics. However, the popularity of this approach has outpaced the evidence of its positive outcomes. To help close that gap, this empirical study reports positive results from Northeastern’s program that embeds values analysis modules into CS courses. The resulting data suggest (...) that such modules have a positive effect on students’ moral attitudes and that students leave the modules believing they are more prepared to navigate the ethical dimensions they’ll likely face in their eventual careers. Importantly, these gains were accomplished at an institution without a philosophy doctoral program, suggesting this strategy can be effectively employed by a wider range of institutions than many have thought.

Based on video-recordings of several weeks of rehearsals of a Japanese theater piece played by French actors, and adopting an ethnomethodological and conversation analytic perspective, this paper focuses on how the same few lines of a scene are subsequently enacted. In particular, it explores how the scene is played, not only in relation to the script but also to the situated moment-by-moment unfolding of embodied movements constituting the actions and achieving their detailed formatting and meaning. Whereas the dialogue refers to (...) the scripted text, we argue that the multimodal details of each scene constitute a unique situated course of action achieved for ‘another first time,’ whose multimodal configuration depends on the temporality and the shape of each step, gesture, and body posture, as they are embodied and responded to in the vivid present and its contingencies. We demonstrate this by revealing how variations of the scene are performed, explored, and serendipitously found by the actors. We focus in particular on embodied details like walking, sitting, hugging and kissing, and the sequential and temporal positions at which they co-occur with the lines of the script. The analysis demonstrates both the indexicality of the script interpretations and the creative contingencies of the embodied work of the actors. In this way, it aims at contributing to current growing literature revisiting theater rehearsal as a situated activity and an interactional multimodal achievement. (shrink)
