The logic of discovering and that of justifying have been a permanent source of debate in mathematics, because of their different and apparently contradictory features within the processes of production of mathematical sentences. In fact, a fundamental unity appears as soon as one investigates deeply the phenomenology of conjecturing and proving using concrete examples. In this paper it is shown that abduction, in the sense of Peirce, is an essential unifying activity, ruling such phenomena. Abduction is the major ingredient in (...) a theoretical model suitable for describing the tran-sition from the conjecturing to the proving phase. In the paper such a model is introduced and worked out to test Lakatos' machinery of proofs and refutations from a new point of view. Abduction and its categorical counter-part, adjunction, allow to explain within a unifying framework most of the phenomenology of conjectures and proofs, encompassing also the method of Greek analysis-synthesis.

O advento da sociedade em rede promoveu mudanças significativas na experiência-com-o-mundo. Observa-se nos últimos anos a crescente toxidade no ambiente informacional, marcado tanto pela vivência tóxica da informação que circula legalmente nas redes sociais como por informações que intoxicam os indivíduos e grupos. O objetivo é discutir, em tempos de pós-verdade e da sociedade non-stop, o aspecto tóxico da informação, que ao tornar o ambiente informacional tóxico, adoece indivíduos e também as sociedades democráticas, ao esmaecer a empatia para com os (...) demais e de pôr em risco a própria ideia de democracia e de vida partilhada de modo democrático. A proposta é discutir a intoxicação pela informação não pelo excesso (infoxicação), mas pelo que nomeio informação tóxica, i.e., o aspecto tóxico da informação e de ambiente informacional tóxico tendo como referência os discursos de ódio. Para tanto serão consideradas a desconstrução de experiências de estados democráticos mediante o crescimento da circulação de discursos de ódio e de discursos de ódio fascistas; o crescimento da desinformação; o crescimento da circulação de notícias fraudulentas (Fake news) e de notícias falsas (por exemplo, as não endossadas pelos saberes científicos, como o terraplanismo, a ideia da supremacia branca); os robots e os algoritmos.

In pluralistic deliberative settings, where people come from different cultural and social backgrounds, sharing personal experiences and narratives in the first person is often advocated as a preferential means to bridge the informational and motivational gap between members of different social groups. Whatever the epistemic merits of personal storytelling in democratic deliberation may be, the request for transparency and disclosure of people’s private experiences that this practice entails may be objectionable on moral grounds, because it disrespects people as agents who (...) have practical authority over their own lives. Having people disclose their personal stories in public can humiliate them, reify them and abridge their personal liberties. What is worse, these harms are especially likely to be inflicted upon members of marginalised or disadvantaged minorities. For deliberativists, this should be a matter of concern because respect for people as agents is arguably one of the founding principles of democratic deliberation. (shrink)

Public deliberation has been defended as a rational and noncoercive way to overcome paradoxical results from democratic voting, by promoting consensus on the available alternatives on the political agenda. Some critics have argued that full consensus is too demanding and inimical to pluralism and have pointed out that single-peakedness, a much less stringent condition, is sufficient to overcome voting paradoxes. According to these accounts, deliberation can induce single-peakedness through the creation of a ‘meta-agreement’, that is, agreement on the dimension according (...) to which the issues at stake are ‘conceptualized’. We argue here that once all the conditions needed for deliberation to bring about single-peakedness through meta-agreement are unpacked and made explicit, meta-agreement turns out to be a highly demanding condition, and one that is very inhospitable to pluralism.

RESUMEN El tema principal de este trabajo es la posición que suele atribuirse a Antístenes de que es imposible contradecir o decir falsedades y su vinculación con el problema metafísico central del Sofista, el del No Ser. La imposibilidad de contradecir es presentada como la posición opuesta a la de la sofística entendida como contradictor en Sof., 232b y ss., cuyo relativismo es asociado con la figura de Protágoras, más específicamente con su tesis de que sobre cualquier cuestión hay dos (...) argumentos opuestos entre sí. Nos proponemos argumentar a favor de la hipótesis de que esta posición que en el diálogo es atribuida a Parménides es la de Antístenes, discípulo de Sócrates y rival teórico de Platón. ABSTRACT The main subject of this article is the philosophical view often attributed to An-tisthenes that it is impossible to contradict and to speak falsely and it's link to the Sophist's nodal metaphysical problem, that ofNot Being. The impossibility of contradiction is presented as the opposite position to sophistry as contradiction, thus defined in So/, 232b ff., which is attributed to Protagoras, specifically to his statement that about any subject there are two opposite lógoi. We will argue that this position that is attributed to Parmenides in this dialogue belongs to Antisthenes, who was Socrates' disciple and Plato's theoretic rival. (shrink)

Music in dreams is rarely reported in scientific literature, while the presence of musical themes in dreams of famous musicians is anecdotally reported. We did a systematic investigation to evaluate whether the occurrence of musical dreams could be related to musical competence and practice, and to explore specific features of dreamt pieces. Thirty-five professional musicians and thirty non-musicians filled out a questionnaire about the characteristics of their musical activity and a structured dream log on the awakening for 30 consecutive days. (...) Musicians dream of music more than twice with respect to non-musicians; musical dreams frequency is related to the age of commencement of musical instruction, but not to the daily load of musical activity. Nearly half of the recalled music was non-standard, suggesting that original music can be created in dreams. (shrink)

Although early‐life adversity has been associated with negative consequences during adulthood, growing evidence shows that such adversity can also lead to subsequent stress resilience and positive fitness outcomes. Telomere dynamics are relevant in this context because of the link with developmental conditions and longevity. However, few studies have assessed whether the effects of early‐life adversity on developmental telomere dynamics may relate to adult telomere dynamics. We propose that the potential links between early‐life adversity and adult telomere dynamics could be driven (...) by developmental constraints (the Constraint hypothesis), by the nature/severity of developmental adversity (the Resilience hypothesis), or by developmental‐mediated changes in individual life‐history strategies (the Pace of Life hypothesis). We discuss these non‐mutually exclusive hypotheses, explore future research directions, and propose specific studies to test these hypotheses. Our article aims to expand our understanding of the evolutionary role of developmental conditions on adult telomere dynamics, stress resilience and ageing. (shrink)

This essay aims to vindicate the importance of a theory of ordinary citizens' political prudence in a democratic society. It follows a reconstructive method, by looking at the full range of powers and decisions that are enabled by democratic rights in order to show that in contemporary democracies there is room for the exercise of political prudence by ordinary citizens. By the same method, it also reconstructs the main traits and manifestations of citizens' political prudence in the everyday politics of (...) our democracies. Theorizing citizens' political prudence is important for detecting and correcting the ways in which the citizens of a democratic society, as well as its institutions, may fail to fulfil the mandates of such an essential political virtue.

Skill transfer is a process in which cognitive and behavioral abilities are applied in another context different from the one in which they were originally learned. Literature demonstrated that this transferability is possible; studies highlight the application of skills from sport to other life-domains (e.g. school, work, health management) with the aim to improve individual characteristics and reach personal goals. Some factors such as positive communication, adequate context, a person-centered perspective and specific strategies are necessary. The objective of the present (...) contribution is to explore the connection between sport and health management skills to enhance the coach/athlete relationship as well as the patient/physician one. Useful strategies of skills transfer from sport to cancer management are shown. (shrink)

This article describes the methods involved in building a diachronic multilingual corpus devoted to Fine Arts, beginning with G. Vasari's Lives of the most excellent Italian architects, sculptors and painters (1568) as the fundamental source text in the field of Art History. Attention is given to automatic pre-alignment, the special proofreading protocol and segmentation rules developed to allow multilingual and/or diachronic alignment of multiple texts, and the difficulties inherent in annotating a multilingual database. A case study is offered, comparing the (...) term “tondo” and its variants (e.g. “mezzo tondo”, “di tondo rilievo”) in Italian with their translations in English (De Vere 1912-15) and French (Leclanché 1839, Chastel 1981, Luciani 2002, Powell 2007). These later translations contain a greater variety of both lexicalized counterparts such as “medallion” or “lunette” as well as paraphrases, used to disambiguate and distinguish the various meanings of “tondo”, thus demonstrating how artistic vocabulary, which was still developing in 16th c. Italian, through its transmission to other languages, became more diversified and stable over time. (shrink)

In this article, we tackle the phenomenon of what seems to be a misunderstanding between science education theory and philosophy of science−one which does not seem to have received any attention in the literature. While there seems to be a consensus within the realm of science education on limiting or altogether denying the explanatory role of scientific laws (particularly in contrast with “theories”), none of the canonical models of scientific explanation (covering law, statistical relevance, unification, mechanistic-causal, pragmatic) lends any support (...) to this view of laws. We will reconstruct three different versions of this demotion of laws (i.e., laws are merely descriptive; laws are explanatory only of singular events, not of laws; laws are explanatory but only in a “superficial” way), propose possible grounds for them and illustrate why these perspectives pose a conceptual challenge as they contrast with epistemological approaches to the problem of explanation. We will also suggest the potential negative outcomes that would arise from science teachers adopting these approaches in the classroom when aiming to assist students in moving beyond mere description and towards explanation.

AimUnderstanding interrelations between the factors predicting students’ aggressive behavior is a priority for bullying-prevention programs. Our study explores two possible mechanisms linking school disciplinary structure and students’ aggression. We test students’ moral disengagement and bullying by teachers as mediational pathways from school authoritative discipline to students’ aggressive behavior.MethodsWe used a regionally representative sample of 213 schools that participated in a school climate survey in Kaluga Oblast (a federal subject of Russia) in 2019. The analytical sample contained the anonymous responses of (...) 16,809 students from grades 6–9 (12–15 years old); 51% of the respondents were girls. The analytical procedure consisted of structural equation modeling (SEM), which was implemented in Mplus 8.7.ResultsThe mediation model fit the data well, suggesting that the clarity and fairness of school rules negatively predicted peer aggression, while student moral disengagement and bullying by teachers independently and partially mediated this association.ConclusionWe confirm that authoritative school climate, characterized by a clear and fair disciplinary structure, is associated with a decrease in bullying. Novel result is the evidence for mediating mechanisms and the influence of teachers’ aggression on students’ behavior. Prevention programs designed to increase the fairness and consistency of school rules, eliminate bullying and humiliation from teachers, and decrease students’ moral disengagement may reduce violence and victimization at school.

In the past 10 years, contemporary philosophy of mathematics has seen the development of a trend that conceives mathematics as first and foremost a human activity and in particular as a kind of practice. However, only recently the need for a general framework to account for the target of the so-called philosophy of mathematical practice has emerged. The purpose of the present article is to make progress towards the definition of a more precise general framework for the philosophy of mathematical (...) practice by exploring two strategies. A first strategy is to turn to philosophy of mind and Edwin Hutchins' view of distributed cognition in order to better understand the cognitive issues at play when considering a community of mathematicians; a second strategy is to refer to philosophy of language and focus on Robert Brandom's inferentialism and mathematical conceptual content. A possible combination of these two views, called enhanced material inferentialism, is then put forward as a promising framework to account for the philosophy of mathematical practice. (shrink)

Resumen Propongo interpretar la inversión de Deleuze del platonismo como la creación de conceptos nuevos a partir de elementos teóricos tomados de la filosofía del propio Platón. En primer lugar, consideraré el origen nietzscheano de la inversión y su interpretación heideggeriana, de la cual, creo, Deleuze se vale para ciertos argumentos. En segundo lugar, me basaré en la hipótesis de Francis Wolff e Isabelle Ginoux de que la filosofía platónica tiene un carácter ambiguo en la obra deleuziana para analizar esa (...) ambigüedad en términos de la pregunta por los elementos positivos que Deleuze rescata para la creación de una nueva imagen del pensamiento.I propose to interpret the deleuzian reversal of Platonism as the creation of new concepts from the same elements the French philosopher extracts from Plato’s thought. To justify this I will first examine the nietzschean origins of the reversal as well as Heidegger’s interpretation of it, which I think inspires Deleuze. Then, based on the works of Francis Wolff and Isabelle Ginoux, I will explore the ambiguity of Plato’s role in Deleuze’s philosophy, especially in those elements he recovers and exploits to build a new image of thought.

Guided by a phenomenological perspective, this paper aims to account for the existence of a corporeal consciousness—something that clinicians should take into account, not merely in the case of physical pathologies but especially in the case of mental disorders. Firstly, I will highlight three cases: schizophrenia, depression, and autism spectrum disorder. Then, I will show how these cases correspond to three different kinds of bodily existence: disembodiment (in the case of schizophrenia), chrematization (in melancholic depression), and dyssynchrony (in the autism (...) spectrum disorder). Finally, I will argue for the importance of an “expressive common environment” between the patient and the clinician, who are two distinct, embodied conscious subjects resonating with one another. In this view, the primary goal of the therapeutic process seems to develop a shared understanding of the patient’s life-world, which finds its main expression through the disrupted body. (shrink)

Equal respect for persons is often appealed to as the grounding principle of democratic rule. I argue here that if it needs to account for the specific content of democratic political rights, it must be understood as respect for people as competent political decision-makers. However, the claim that respect is due to people as a response to their actual equal competence leads to a conflation of democratic legitimacy and substantive justice, resting on implausible factual assumptions and making it impossible to (...) advocate the effective equalization of political capabilities. Therefore, I suggest that the principle of equal respect should be decoupled from such a claim and be rephrased as simply prescribing that people be treated or publicly recognized as equally competent. I defend this interpretation against the publicity objection, according to which this take on the principle implies insincerity and therefore cannot serve as a public justification for democratic authority.

Loneliness is more complex and multi-faceted than it may appear at first glance. Most of the characterizations that we have of loneliness in the extant literature tend to focus on the absence of other people and on the social, mental, and physical distress that can be caused by this type of absence. Although the experience of absence may be a fundamental and encompassing aspect of loneliness, loneliness may also reflect a deeper, more complex experience. This paper integrates data from a (...) qualitative study on the phenomenology of loneliness with philosophical theories on the self. It argues that there is a connection between the experience of absence and the impossibility to appear in the world and that this may consequentially lead to the disruption of self-experience.

The objective of this article is to take into account the functioning of representational cognitive tools, and in particular of notations and visualizations in mathematics. In order to explain their functioning, formulas in algebra and logic and diagrams in topology will be presented as case studies and the notion of manipulative imagination as proposed in previous work will be discussed. To better characterize the analysis, the notions of material anchor and representational affordance will be introduced.

Authentic human life is the open-ended dialogue. Life by its very nature is dialogic. To live means to participate in dialogue: to ask questions, to head, to respond, to agree, and so forth. In this dialogue a person participates wholly and throughout his whole life: with his eyes, lips, hands, soul, spirit, with his whole body and deeds. He invests his entire self in discourse, and this discourse enters into the dialogic fabric of human life, into the world symposium. (Bahktin, (...) 1984, p. 283)... (shrink)

It is often argued that in order to prevent migration from having social dumping effects, a strict enforcement of equal labour and welfare rights for both migrants and local workers is required. However, we claim that the specific circumstances of those migrants who engage in temporary migration may require a regime of special rights and labour standards that protect and further their distinctive interests and needs. We defend this claim by appealing to the principle that labour and welfare rights should (...) accommodate the life plans of workers and we show that not only these special arrangements are fairer to the migrants involved, but they could also help to prevent social dumping.

It is possible to argue that the only ‘genuine’ experiments in mathematics are in fact thought experiments. Nevertheless, one preliminary question is to ask what genuine mathematica experiments are, and whether the activity of experimentation is a proper mathematical activity. In this article, I will consider which kind of conception of mathematics allows for the existence of experiments in mathematics and I will present the constraints these experiments are subject to. Then, I will discuss three examples to arrive at a (...) general conclusion: experimentation is indeed a genuine mathematical activity, but its mechanisms are particular with respect to experimentation in the natural sciences.

This introduction aims to familiarize readers with basic dimensions of variation among pictorial and diagrammatic representations, as we understand them, in order to serve as a backdrop to the articles in this volume. Instead of trying to canvas the vast range of representational kinds, we focus on a few important axes of difference, and a small handful of illustrative examples. We begin in Section 1 with background: the distinction between pictures and diagrams, the concept of systems of representation, and that (...) of the properties of usage associated with signs. In Section 2 we illustrate these ideas with a case study of diagrammatic representation: the evolution from Euler diagrams to Venn diagrams. Section 3 is correspondingly devoted to pictorial representation, illustrated by the comparison between parallel and linear perspective drawing. We conclude with open questions, and then briefly summarize the articles to follow. (shrink)

In light of the recent debate over post-truth or post-fact politics, Arendt’s work provides important insights on the relationship between truth and politics. While some scholars argue that Arendt regards truth as antagonistic to politics, others focus on her notion of truth of facts in politics. We assert that, for Arendt, truthfulness is essential for politics, but the truthfulness of political actors involves more than the willingness to acknowledge and recognise facts. We read Arendt’s essay “Socrates” and elicit three expectations (...) regarding the truthfulness of political actors: the willingness to constitute one’s own doxa, the willingness to actively engage in dialogue with others and relate one’s doxa to theirs, and the willingness to develop an ongoing practice of “enlarged thought” by sustaining a mental conversation with a variety of doxai in one’s imagination. We find that this threefold notion of truthfulness is of ultimate political importance since it plays an essential role in the human ability to bring to life relationships of plurality and to constitute a “common world.” Our analysis allows us to articulate the challenges associated with practicing truthfulness in the contemporary political realm and the conditions that could enable political actors to take on this practice.

The following paper explores the categorisation of groups. Indeed, there are different ways to distinguish human groups from one another: on the one hand, sociological analyses focus their attention on the distinction between being inside and outside of groups; on the other hand, collective action theories mainly focus on the distinction between collectives and aggregates, based on the kind of action that groups can perform, i.e., joint or not. In this paper, we offer an alternative view by adopting the agent’s (...) perspective and creating a scale based on the importance the agent attributes to his or her membership to different groups. While this perspective seems to lose objectivity as it does not allow the formulation of an unambiguous scale that applies to all individuals, it does allow us to understand the process of identification and the consequent phenomenon whereby very often we act in accordance with other people’s actions, in a collective way, without prior coordination. A practical example based on the so-called “acting white” will be explored in order to test the paper’s proposal. The analysis intends to offer a common ground on the basis of which it would be possible to have further inquiries on the social dimension of self-experience. (shrink)
