Epicurus’ original version of atomism takes atoms to be physically indivisible but not completely unanalysable: each atom contains a finite number of minima. This paper explores the nature of the minima by focusing on a specific question: in which sense are the minima minimal? I do so by investigating the notions of parthood and divisibility into parts that are at play in paragraphs 56–59 of the Letter to Herodotus, where the theory of minima is introduced. By focusing on the analogy (...) (noticed by Francesco Verde) between Epicurean minima and Aristotelian limits, I argue that the minima should be understood as the minimal realiser of the atom’s physical functions. This allows me to keep together two very plausible but apparently incompatible claims: (i) the minima are supposed to block the paradoxes of theoretical divisibility, but (ii) their existence and their indivisibility can only be justified in physical (rather than geometrical) terms.

Neste artigo, concentro-me sobre quatro variedades possíveis de ausência da vergonha. Minha esperança é a de que a reflexão sobre essas variedades possa, de alguma maneira, nos dar uma imagem mais completa acerca do papel que a vergonha desempenha sobre nosso caráter moral e nas discussões a respeito da atrocidade. Observo que a vergonha que emerge de uma exposição à atrocidade pode em parte constituir aquilo que nos leva a identificar oevento como atroz. Prossigo então argumentando que quando a vergonha (...) está ausente, esta ausência pode servir para nos cegar para a atrocidade que está à nossa frente, e que é nossa tarefa tentar evitar. Sentir vergonha faz parte de ver a atrocidade pelo que ela é de uma maneira apropriada emocionalmente engajada. Ela é, portanto, uma parte vital de ser humano, e sua ausência em certos casos é uma insuficiência demasiadamente humana de humanidade. (shrink)

The research that I have carried out on the sense of hearing in the Aristotelian ambit is based on a personal interest in the medical aspects that can be found in the treaties of the Stagirite. If, on the one hand, there has always been very deep attention by the scholars to the phenomenon of perception, and still there is, on the other hand, although not ignored, hearing remains perhaps somewhat neglected or, however, not sufficiently investigated so far, despite its (...) importance; but, above all, the effort to consider all its various implications together and the whole Corpus Aristotelicum has not been accomplished up to today. This is the intent that I have purposed and which I hope to have at least partially achieved. Of course, it was a constant need to refer also to the other senses and, in general, to Aristotle's theory of perception; I have, however, tried to point out every possible aspects, which could explain the peculiarities of hearing. Without claiming in any way to draw up a rank list of the senses, since each of them, according to the different points of view, seems more or less to aspire to a kind of primacy, I was able to demonstrate the extraordinary importance of hearing and, within certain limits, his preferability. After an introductory chapter on the position of hearing among the other senses, I have proposed a rather long one, in which I more specifically dealt with the anatomical, physiological and pathological aspects (and, finally, even some physical-mathematical considerations, that I think of great philosophical and scientific relevance); then, it has been given ample space (and could not be otherwise) to the complex issue of the relationship between hearing and language, which made it possible to highlight, thanks to the comparative approach of the Aristotelian investigations in the biological ambit, the differences between sound, voice and speech, and to show the key role of hearing in order to learning (also animal) and intellectual development (especially human). In a final articulated chapter I approached what I consider the further possible implications of hearing, always clinging to the Aristotelian treatment: in addition to the physical phenomena of echo, roar, resonance and the psychophysicist ones of acoustic illusions, I could not exempt myself from talking about music, also in "technical" terms (as my limited skills in the field have allowed me to), but especially because of its educational features examined in the paragraph Emotions, morality and education, where hearing is reported as undisputed protagonist in the ethical, aesthetic, rhetorical, political ambits; the chapter, and the dissertation itself, are closed by some remarks about the relations of hearing with memory and recollection and with dream: apart from the latter, where sight seems to dominate, with the first two the auditory role is on the contrary of primary importance, despite still today people are often inclined to mention visual memory more frequently. Even from these few notes I think I can state that it was really worthwhile to dedicate a research to the sense of hearing, especially in regard to a Corpus so broad, rich, varied and complex, such as the Aristotelian one.

La circulation du savoir philosophique à travers les traductions du grec au syriaque, du grec à l'arabe, du syriaque à l'arabe, de l'arabe au latin forme, depuis un siècle et plus de recherches savantes, un domaine scientifique à part entière. Ce volume réunit des spécialistes des disciplines du domaine voulant rendre hommage à un collègue dont l'activité a ouvert une voie, Henri Hugonnard-Roche. Spécialiste de la transmission du grec au syriaque de la logique aristotélicienne, Henri Hugonnard-Roche a montré par ses (...) recherches la continuité entre la philosophie de l'Antiquité tardive et la pensée des chrétiens de langue syriaque d'un côté, des savants musulmans écrivant en arabe, de l'autre. Réunis souvent par ce que Werner Jaeger avait autrefois désigné comme 'la portée œcuménique de l'Antiquité classique', des musulmans et des chrétiens faisant partie d'un cercle philosophique se penchaient, dans la ville de Bagdad au Xe siècle, sur le texte d'Aristote. Leur 'Aristote' était souvent celui de l'Antiquité tardive : l'Aristote de l'école néoplatonicienne d'Alexandrie que les intellectuels de la Syrie chrétienne avaient déjà rencontré quelque quatre siècles auparavant et qu'ils avaient traduit, en même temps que Galien, et parfois commenté. Des noms presque inconnus comme celui de Sergius de Resh'ayna (mort en 536) commencent dans nos manuels à en côtoyer d'autres bien plus connus, comme celui de Boèce, grâce aux recherches de Henri Hugonnard-Roche.

[E.H. Gombrich wrote on May 13, 1975:] . . . I recently was invited to talk about "Art" at the Institution for Education of our University. There was a well-intentioned teacher there who put forward the view that we had no right whatever to influence the likes and dislikes of our pupils because every generation had a different outlook and we could not possibly tell what theirs would be. It is the same extreme relativism, which has invaded our art schools (...) and resulted in the doctrine that art could not possibly be taught because only what has been done already can be taught, and since art is creativity it is not possible to teach it. Q.E.D.—I recently asked my history finalists what "Quod erat demonstrandum" means and they did not know. . . . [Quentin Bell responded on May 15, 1975:] . . . Your teacher at the Institute, is he really a relativist? Isn't he a kind of religious zealot? I used to teach school children. With me there was a much better teacher . One day she came into the room where I had been teaching and found a series of the most surprising and beautiful water colours. "What are these?" said she. I explained that they were copies of Raphael made by eleven and twelve year old children. I would have gone on to explain how interested I was by their resemblance, not to Raphael but rather to Simone Martini, for they had all the shapes beautifully right but none of the internal drawing or the sentiment, but I was checked by her look of horror. "You've made them copy from Raphael?" she said. Her expression was exactly that of someone who had been casually informed that that I had committed a series of indecent assaults upon the brats. And in fact in subsequent conversation it appeared that this was very nearly what she did feel. For her, what she called "self expression" was as precious as virginity. E.H.

In lieu of an abstract, here is a brief excerpt of the content:Playing the Dummy:Maugham, Smartphones, and the End of EleganceEric BronsonIOn the Russian Trans-Siberian train from Vladivostok to Petrograd (now St. Petersburg), an American businessman won't stop talking for the entire ten-day journey. In his story, "A Chance Acquaintance," W. Somerset Maugham describes this 1917 meeting between Ashenden, a British character loosely based on himself, and the chatty American, named Harrington. The two passengers are blissfully unmoved by the revolution (...) unfolding all around them. Ashenden casually suggests the two of them try and find another pair to pass the time playing bridge. Harrington refuses. "It beats me how an intelligent man can waste his time card-playing," Harrington asserts, "and of all the unintellectual pursuits I have ever seen it seems to me that solitaire is the worst. It kills conversation. Man is a social animal and he exercises the highest part of his nature when he takes part in social intercourse."1 Ashenden doesn't understand the American's distaste for playing cards, especially bridge. "'There is a certain elegance in wasting time,' said Ashenden. … 'Besides,' he added with bitterness, 'you can still talk.'" [End Page 477]Like many of his fictional characters, Maugham enjoyed eloquent, "time-wasting" games like bridge. Unlike solitaire, bridge encourages social interaction. Once, when his confounded bridge partner confronted Maugham with evidence that his high-class opponents were cheating, Maugham was nonplussed. "They gave us double Martinis to start with," he noted, "a slap-up lunch with a particularly good bottle of white Burgundy and old brandy with our coffee."2 The dishonesty was irrelevant. For Maugham, a good bridge game, like the attendant conversation, should help temper one's moral outrage and skim over the unruly passions that so often plague our public and private lives. Elegance, for Maugham, meant presenting the appearance of calm and respectability, especially when such presentations conflicted with one's more turbulent emotions.In Maugham's short story "The Three Fat Women of Antibes," the women around the bridge table desperately try to keep up appearances, both physically and emotionally. When passionate arguments inevitably threaten to undo the air of genteel conversation, Lena, the newest addition to the table, states, "I think it's such a pity to quarrel over bridge. … After all, it's only a game."3 But while it might be true that bridge is "only a game," Maugham took games seriously. Parlor games like bridge were spaces to practice and perfect the social mores on which colonial hierarchies were solidified. In Maugham's England, the game of life required an elegant performance of the many roles the genteel class was expected to play. That performance was predicated on a relentless effort to keep up ordinary appearances by regulating emotional displays. As Maugham wrote in a 1944 article for Good Housekeeping, a good bridge game rewards people who are "truthful, clearheaded, and considerate," characteristics essential "for playing the more important game of life."4More than any other card game, bridge is built on conventions. Etiquette dictates how cards are shuffled, passed, and played. While there is always some room for surprise and risk, everyone around the table needs to know the bidding and playing conventions to ensure the best possible game. In every hand a silent partner, known as the dummy, lays their cards face up, thereby taking themself out of the action.The persistence of such conventions is a holdover from the game of whist, the predecessor of bridge. In an early-nineteenth-century story, "Mrs. Battle's Opinions on Whist," essayist Charles Lamb describes an elderly whist player who enjoys the elegant waste of time that such long card games encourage. While dances and parties help build social skills around untrustworthy passions, card games like whist, and later bridge, [End Page 478] were more like "a long meal; not like quadrille, a feast of snatches. One or two rubbers might co-extend in duration with an evening. They gave time to form rooted friendships." This kind of congeniality mattered to serious people like Mrs. Battle, people who "despised superficiality, and looked deeper than the colours of things."5The game of bridge... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:There are only three surviving biographical notices regarding Marcus of Orvieto: two as colophons of Vatican manuscripts and a third as an entry in a catalog of the papal library in Avignon where we read: "Item, liber de mortalitatibus septem Martini de Urbevetani Ordinis Minorum." While the spelling of the book title and its author can be attributed to scribal errors or misreadings, the 'seven,' place of origin, (...) and religious order affiliation are accurate. Marcus's Liber de Moralitatibus is indeed divided into seven treatises: On the celestial bodies, On the elements, On the birds, On the fish, On the animals, On trees and plants and On precious gems. The colophons of the two Vatican manuscripts attest to his being a Friar Minor: Ego frater Marcus Urbis Veteris Fratrum Minorum Ordinis pauperculus. The prooemium of the Liber de Moralitatibus attests to the fact that Marcus's patron was Benedict Gaetani cardinal of St. Nicholas in carcere Tulliano,' the future pope Boniface VIII. This would put the time of composition circa 1290. Several allusions in Marcus's work to Paris, viz. the Parisian masters, its patron Ste. Genevieve, indicate that Marcus was at one time a student there and it is conceivable that Benedict commissioned the work while he was a papal legate there. Marcus's opus falls into the category of exempla literature, i.e. a source book for preachers.We offer the English translation of the chapter on pelicans as typical of Marcus's way of proceeding which, generally speaking, is threefold. First a physical description, which was generally copied from Bartholomew of England's 'On the Properties of Things,' secondly its spiritual signification attested to by pertinent passages from Scripture and bolstered by citations from the Fathers and Doctors of the Church, and thirdly examples of persons who exemplify the spiritual lesson either supportively or adversely. The legend of the pelican piercing its breast in order to revivify its dead chicks was familiar in Christian literature and art signifying analogously Christ's salvific blood redeeming the human race from its fallen state. The following is the English translation of Marcus's treatise 3, 'De avibus,' chapter 31.Chapter 31: On the pelicanThe pelican is seen to possess the following conditions or properties according to the doctors.1. First of all, as Isidore says, it is a "bird dwelling in solitude along the banks of the Nile." This signifies preachers and contemplative persons who flee the vanities of the world and occupy themselves with heavenly consolations or delightful and re-creative consolations of Sacred Scripture, Psalm 54, 8-9: Far away I would flee; I would lodge in the wilderness. I would hasten to find shelter from the violent storm and the tempest. Bernard, On the Canticle of Canticles and in his sermons: "Divine consolation is delicate, it is not given to those preoccupied with what is alien to it." Ambrose, On Luke: "Those preoccupied with secular vanities cannot know what is divine."2. Secondly, as Isidore says, whatever it eats, it first dips in water with its foot and having done so, using the foot as a hand as it were, puts it [the morsel] in its mouth. This signifies doctors [i. e. teachers] and preachers who practice what they teach or preach after the example of the Apostle, Romans 15, 18: I will not dare to speak of anything except what Christ has accomplished through me. Jerome, To Nepotian: "Make sure your deeds do not 'confound' your words, lest when you speak in the assembly someone might say to himself: 'Physician, cure yourself'."3. Thirdly, as Isidore says, of all the birds, with the exception of the phylargum, only the pelican uses its foot as a hand. This signifies a devout religious who frequently, motivated by holy desires and affections, prefers holy meditations rather than manual labor. 1Tim. 4: 7-8: Train yourself for devotion, for while physical training is of..

Reading Tye’s new book reminded me of slowly sipping a good specimen of a dry vodka Martini. In both cases much is accomplished by the skilful assembly of only a few key ingredients. I don’t really like dry vodka Martinis, though, and similarly I found many of the thoughts offered by Consciousness Revisited to be too bitter to swallow. A sophisticated piece of work, however, it certainly is.

Knowledge brokers are among the main channels of communication between scientists and the public and a key element to establishing a relation of trust between the two. But translating knowledge from the scientific community to a wider audience presents several difficulties, which can be accentuated in times of crisis. In this paper we study some of the problems that knowledge brokers face when communicating in times of crisis. During the first wave of the COVID-19 pandemic, we collected interviews with Italian (...) experts that played a major role as knowledge brokers in the local media. We asked them questions about five main topics: the features and role of science communicators; the use of language in communicating science; the importance of the relation of trust with the public; the peculiarity of communicating in a context of emergency; the problem of disagreement among experts, and its public perception and communication. The goal of this paper is to understand, through the words of knowledge brokers themselves, what they consider as best practices (and obstacles) to create trust between scientists and the public. Our empirical work can inform normative accounts of what knowledge brokering should be about. (shrink)

Two quantum Macro-states and their Macroscopic Quantum Superpositions (MQS) localized in two far apart, space-like separated sites can be non-locally correlated by any entangled couple of single-particles having interacted in the past. This novel “Macro-Macro” paradigm is investigated on the basis of a recent study on an entangled Micro-Macro system involving N≈105 particles. Crucial experimental issues as the violation of Bell’s inequalities by the Macro-Macro system are considered.

This paper explores the scope and limits of rational consensus through mutual respect, with the primary focus on the best known formal model of consensus: the Lehrer–Wagner model. We consider various arguments against the rationality of the Lehrer–Wagner model as a model of consensus about factual matters. We conclude that models such as this face problems in achieving rational consensus on disagreements about unknown factual matters, but that they hold considerable promise as models of how to rationally resolve non-factual disagreements.

Some philosophers claim that perception immediately and prima facie justifies belief in virtue of its phenomenal character (Huemer, Skepticism and the veil of perception. Rowman & Littlefield, Lanham, 2001; Pryor, There is immediate justification. In: Steup M, Sosa E (eds) Contemporary debates in epistemology. Blackwell, London (2014), pp. 181–202, 2005). To explain this special justificatory power, some appeal to perception’s presentational character: the idea that perceptual experience presents its objects as existing here-and-now (Chudnoff, Intuition. Oxford University Press, Oxford, 2013; Berghofer, (...) Husserl Stud 34(2):145–170, 2018). As some philosophers have noted, if perception justifies in virtue of its presentational character alone, the kind of content perception has should not matter for perceptual justification; more precisely, it should not matter whether perceptual content is propositional or not (e.g., Smithies, The epistemic role of consciousness. Oxford University Press, Oxford, 2019; Kriegel, Australas J Philos, 2021). However, most philosophers tend to resist this conclusion, holding that perception must be propositional in order to justify, on the ground that all our model of justification are propositional (e.g., Gauker, Philos Perspect 26(1):19–50, 2012). This paper challenges this claim. The paper consists of a negative and a positive part. In the negative part, I discuss and reject the master argument for the propositionality of perception; the conclusion is that propositional content is neither sufficient nor necessary to explain perception’s justificatory power. In the positive part, I take this conclusion seriously and outline an objectual model of perceptual justification. I define objectual attitudes as mental states whose content is not a full proposition, but a sub-propositional representational item, such as the representation of objects, properties, and kinds (Grzankowski and Montague, Non-propositional intentionality. Oxford University Press, Oxford, 2018), and show that it is plausible that some perceptions and some beliefs are attitudes of this kind. I then argue that objectual perceptual experiences have the right kind of phenomenal character and the right kind of structure to serve for immediate prima facie justification. I conclude by defending my objectual model from three objections. (shrink)

Despite a long history of researchers who combine phenomenology with qualitative or quantitative methods, there are only few examples of working with a phenomenological mixed method—a method where phenomenology informs both qualitative and quantitative data generation, analysis, and interpretation. Researchers have argued that in working with a phenomenological mixed method, there should be mutual constraint and enlightenment between the qualitative and quantitative methods for studying consciousness. In this article, we discuss what a framework for phenomenological mixed methods could look like (...) and we aim to provide guidance of how to work within such framework. We are inspired by resources coming from research in mixed methods and existing examples of phenomenological mixed-method research. We also present three cases of phenomenological mixed methods where we study complex social phenomena and discuss the process of how we conducted the studies. From both the research inspiration and our own studies, we depict the landscape of possibilities available for those interested in mixing phenomenology with qualitative and quantitative methods, as well as the challenges and common pitfalls that researchers face. To navigate in this landscape, we develop a three-fold structure, focusing on the phenomenological frame, the phenomenologically informed generation of qualitative and quantitative data, and the phenomenologically informed analysis and interpretation of data.

At least since Kuhn’s Structure, philosophers have studied the influence of social factors in science’s pursuit of truth and knowledge. More recently, formal models and computer simulations have allowed philosophers of science and social epistemologists to dig deeper into the detailed dynamics of scientific research and experimentation, and to develop very seemingly realistic models of the social organization of science. These models purport to be predictive of the optimal allocations of factors, such as diversity of methods used in science, size (...) of groups, and communication channels among researchers. In this paper we argue that the current research faces an empirical challenge. The challenge is to connect simulation models with data. We present possible scenarios about how the challenge may unfold. (shrink)

In recent decades much literature has been produced on disagreement; the puzzling conclusion being that epistemic disagreement is, for the most part, either impossible (e.g. Aumann (Ann Stat 4(6):1236–1239, 1976)), or at least easily resolvable (e.g. Elga (Noûs 41(3):478–502, 2007)). In this paper I show that, under certain conditions, an equally puzzling result arises: that is, disagreement cannot be rationally resolved by belief updating. I suggest a solution to the puzzle which makes use of some of the principles of Hintikka’s (...) Socratic epistemology. (shrink)

In this paper, I defend a tripartite metaphysics of intentional mental states, according to which mental states are divided into subject, content, and attitude, against recent attempts at eliminating the attitude component (e.g., Montague, Oxford studies in philosophy of mind, 2022, 2, Oxford University Press). I suggest that a metaphysics composed of only subject and content cannot account for (a) multisensory perceptual experiences and (b) phenomenological differences between episodes of perception and imagination. Finally, I suggest that some of the motivations (...) behind the rejection of the attitude component can be accommodated within the tripartite framework. (shrink)

In this paper I criticize the current standards for the acceptability of expert testimony in current US legislation.

I then investigate the problem of recognizing expertise from the layperson’s (...) standpoint, and suggest what courses of action the future research ought to take on the problem of identifying expertise.

Research in phenomenology has benefitted from using exceptional cases from pathology and expertise. But exactly how are we to generate and apply knowledge from such cases to the phenomenological domain? As researchers of cerebral palsy and musical absorption, we together answer the how question by pointing to the resource of the qualitative interview. Using the qualitative interview is a direct response to Varela’s call for better pragmatics in the methodology of phenomenology and cognitive science and Gallagher’s suggestion for phenomenology to (...) develop its methodology and outsource its tasks. We agree with their proposals, but want to develop them further by discussing and proposing a general framework that can integrate research paradigms of the well-established disciplines of phenomenological philosophy and qualitative science. We give this the working title, a “phenomenological interview”. First we describe the what of the interview, that is the nature of the interview in which one encounters another subject and generates knowledge of a given experience together with this other subject. In the second part, we qualify why it is worthwhile making the time-consuming effort to engage in a phenomenological interview. In the third and fourth parts, we in general terms discuss how to conduct the interview and the subsequent phenomenological analysis, by discussing the pragmatics of Vermersch’s and Petitmengin’s “Explicitation Interview”.

The paper defends the position that phenomenological interviews can provide a rich source of knowledge and that they are in no principled way less reliable or less valid than quantitative or experimental methods in general. It responds to several skeptic objections such as those raised against introspection, those targeting the unreliability of episodic memory, and those claiming that interviews cannot address the psychological, cognitive and biological correlates of experience. It argues that the skeptic must either heed the methodological and epistemological (...) justification of the phenomenological interview provided, or embrace a more fundamental skepticism, a “deep mistrust”, in which scientific discourse can have no recourse to conscious processes as explananda, with ensuing dire consequences for our conception of science.

In this paper we analyze the resilience to decoherence of the Macroscopic Quantum Superpositions (MQS) generated by optimal phase-covariant quantum cloning according to two coherence criteria, both based on the concept of Bures distance in Hilbert spaces. We show that all MQS generated by this system are characterized by a high resilience to decoherence processes. This analysis is supported by the results of recent MQS experiments of N=3.5×104 particles.

We propose a natural deduction calculus for the modal logic S4.2.

Normalization and its consequences are obtained in a natural way, with proofs that closely follow the analogous ones for (...) first-order logic. (shrink)

During recent decades various researchers from health and social sciences have been debating what it means for a person to be disabled. A rather overlooked approach has developed alongside this debate, primarily inspired by the philosophical tradition called phenomenology. This paper develops a phenomenological model of disability by arguing for a different methodological and conceptual framework from that used by the existing phenomenological approach. The existing approach is developed from the phenomenology of illness, but the paper illustrates how the case (...) of congenital disabilities, looking at the congenital disorder called cerebral palsy (CP), presents a fundamental problem for the approach. In order to understand such congenital cases as CP, the experience of disability is described as being gradually different from, rather than a disruption of, the experience of being abled, and it is argued that the experience of disability is complex and dynamically influenced by both intrinsic and extrinsic factors. Different experiential aspects of disability— pre-reflective, attuned and reflective aspects—are described, demonstrating that the experience of disability comes in different degrees. Overall, this paper contributes to the debates about disability by further describing the personal aspects and experience of persons living with disabilities. (shrink)

The concept of evidence has gone unanalysed in much of the current debate between proponents and critics of evidence-based medicine.

I will argue that reconciling the different meanings of the word ‘evidence’ in “evidence-based medicine” should help put EBM in its (...) rightful place. (shrink)

This paper focuses on the question of how to resolve disagreement and uses the Lehrer-Wagner model as a formal tool for investigating consensual decision-making. The main result consists in a general definition of when agents treat each other as epistemic peers (Kelly 2005; Elga 2007), and a theorem vindicating the “equal weight view” to resolve disagreement among epistemic peers. We apply our findings to an analysis of the impact of social network structures on group deliberation processes, and we demonstrate their (...) stability with the help of numerical simulations.

A rigorous ab initio derivation of the (square of) Dirac’s equation for a particle with spin is presented. The Lagrangian of the classical relativistic spherical top is modified so to render it invariant with respect conformal changes of the metric of the top configuration space. The conformal invariance is achieved by replacing the particle mass in the Lagrangian with the conformal Weyl scalar curvature. The Hamilton-Jacobi equation for the particle is found to be linearized, exactly and in closed form, by (...) an ansatz solution that can be straightforwardly interpreted as the “quantum wave function” of the 4-spinor solution of Dirac’s equation. All quantum features arise from the subtle interplay between the conformal curvature acting on the particle as a potential and the particle motion which affects the geometric “pre-potential” associated to the conformal curvature itself. The theory, carried out here by assuming a Minkowski metric, can be easily extended to arbitrary space-time Riemann metric, e.g. the one adopted in the context of General Relativity. This novel theoretical scenario appears to be of general application and is expected to open a promising perspective in the modern endeavor aimed at the unification of the natural forces with gravitation.

We present a syntactical cut-elimination proof for an extended sequent calculus covering the classical modal logics in the \(\mathsf{K}\), \(\mathsf{D}\), \(\mathsf{T}\), \(\mathsf{K4}\), \(\mathsf{D4}\) and \(\mathsf{S4}\) spectrum. We design the systems uniformly since they all share the same set of rules. Different logics are obtained by “tuning” a single parameter, namely a constraint on the applicability of the cut rule and on the (left and right, respectively) rules for \(\Box\) and \(\Diamond\). Starting points for this research are 2-sequents and indexed-based calculi (...) (sequents and tableaux). By extending and modifying existing proposals, we show how to achieve a syntactical proof of the cut-elimination theorem that is as close as possible to the one for first-order classical logic. In doing this, we implicitly show how small is the proof-theoretical distance between classical logic and the systems under consideration. (shrink)

Science progresses through debate and disagreement, and scientific controversies play a crucial role in the growth of scientific knowledge. However, not all controversies and disagreements are progressive in science. Sometimes, controversies can be pseudoscientific; in fact, bogus controversies, and what seem like genuine scientific disagreements, can be a distortion of science set up by non-scientific actors. Bogus controversies are detrimental to science because they can hinder scientific progress and eventually bias science-based decisions. The first goal of this paper is to (...) elucidate the distinction between bogus and genuine scientific controversies and provide a qualitative methodology, based on the literature on expertise, for distinguishing between the two. We will illustrate six epistemic criteria for distinguishing bogus from genuine scientific debates in science and medicine. This heuristic strategy applies directly to scientific reports, and it relies mostly on the social structure of science. We will then apply the above criteria to a case study: the controversy over statins, which are widely prescribed drugs for reducing the level of cholesterol and preventing cardiovascular disease.

In this paper, I contend that evidence-focused strategies of science communication may be complemented by possibly more effective rhetorical arguments in current public debates on vaccines. I analyse the case of direct science communication - that is, communication of evidence - and show that it is difficult to effectively communicate evidential standards of science in the presence of well-equipped anti-science movements. Instead, I argue that effective rhetorical tools involve ad hominem strategies, that is, arguments involving claims of expertise.

Hearsay or indirect testimony receives little discussion even today in epistemology, and yet it represents one of the cardinal modes for the transmission of knowledge and for human cognitive development. It suffices to think of school education whereby a student listens to teachers reporting knowledge acquired, often indirectly, from the most varied sources such as text books, newspapers, personal memory, television, etc… Or let us consider the importance of oral tradition in the social and cultural development of civilisations. Or even (...) let us call to mind the learning process of infants who, only thanks to the knowledge learned from others, succeed in learning the language. Finally, with the emerging digital technology, the information gleaned from third parties is influencing the creation of knowledge in a full gamut of fields, in a quasi-comprehensive manner. This leads us to claim that hearsay, despite the reductionist conceptual scheme to which epistemology has confined it in that indirect testimony, is in any case quintessential in the dissemination of knowledge. This work fully expounds upon the basic mechanism of indirect testimonial transmission and provides an epistemologically founded explanation of the cognitive possibilities of hearsay by investigating, in the light of the anti-reductionist paradigm, three mutually connected epistemic properties, namely trust, reputation and coherence, that are key in the epistemic justification of the truth acquired via an indirect testimony.

We present a sequent calculus for the modal logic S4, and building on some relevant features of this system we show how S4 can easily be translated into full propositional linear logic, extending the Grishin-Ono translation of classical logic into linear logic. The translation introduces linear modalities only in correspondence with S4 modalities. We discuss the complexity of the decision problem for several classes of linear formulas naturally arising from the proposed translations.

Graduate Papers from the 2022 Joint Session. It is often said that Aristotle takes geometrical objects to be absolutely unmovable and unchangeable. However, Greek geometrical practice does appeal to motion and change, and geometers seem to consider their objects apt to be manipulated. In this paper, I examine if and how Aristotle’s philosophy of geometry can account for the geometers’ practices and way of talking. First, I illustrate three different ways in which Greek geometry appeals to change. Second, I examine (...) Aristotle’s ontology of geometrical objects and argue that although the truth-makers of geometrical statements are in fact unmovable because they are properties of sensible objects, geometers ‘separate them in thought’ and treat them as substances apt to be modified. Finally, I examine whether allowing for the possibility of manipulating these semi-fictional geometrical individuals creates problems for the applicability of geometry. I find that it does not, insofar as one accepts that geometry is not meant to track physical change but merely to study the instantaneous geometrical configuration of sensible bodies, and is thus only applicable at the instant.

In this paper I analyze four so-called “principles of expertise”; that is, good epistemic practices that are normatively motivated by the epistemological literature on expert judgment. I highlight some of the problems that the four principles of expertise run into, when we try to implement them in concrete contexts of application (e.g. in science committees). I suggest some possible alternatives and adjustments to the principles, arguing in general that the epistemology of expertise should be informed both by case studies and (...) by the literature on the use of experts in science practice.

We owe our first graphic experiences to Neanderthal Man, who introduced to the cultural baggage of the genus Homo two metaphorical behaviors that are fundamental in terms of their innovation: one concerns the preservation of the bodies of the dead through burial, the other is the making of signs, which in this stage of evolution do not yet represent recognizable subjects but only lines. This attests to the creation of a graphical tool that materializes and makes visible that which exists (...) in the mind, something that is other than itself, thus providing signs of a communication that unfortunately today we cannot define semantically. We cannot say whether these linear marks are a sort of «brand» or if they are carriers of meanings, however, we can observe that, with the Neanderthals, a conceptual, projectual plan exists that enables the measurement of space and the configuration of a regular rhythm, creating an original condition of movement and an association of potentially dynamic lines.
