Mimicry, camouflage, transvestism, chance or cryptic anamorphism, fascination – all ways of changing clothes, habits and habitats in nature as well as in culture, in any symbolic field created by human beings during their history. Art and artification, aestheticization, stylization and beautification are all practices reflecting the need and desire for biological as well as social adaptation, all performances producing functional and fictional frames, boundaries or hierarchies in ordinary life, including the artworld. They can persuade and convince by creating consensus (...) and belief, but they can also lead to a different common sense, a sensorium – a sensorial medium and an aesthetic mediation open to a new world and to new experiences. -/- By investigating mimetism as a fundamental and polymorphic aesthetic performance, this issue of «Aisthesis» aims to rethink the concept, value, and function of mimesis and its media in the context of camouflage, simulation, and dissimulation, where images do not reveal themselves as such, but are to be perceived unambiguously as what they are not – as hieroglyphs or puzzles. In the animal kingdom, as well as in war or in ordinary public life, camouflage consists in taking on the traits, colours, and shapes of a given form or environment. This is a twofold process: on the one hand, by blending two or more shapes in one, the camoufleur seeks to remain hidden and to mislead the others in order to keep a vital secret or an ephemeral whim; on the other hand, however, he/she aims to be recognized by a specific milieu or group, thus betraying a craving for communication and familiarity, as well as a need to convey an agreeable appearance and to share a way of life.

Rodolfo Sacco developed the idea of “mute behaviours” during his studies on mute law. The notion of “mute behaviours” denotes an action that is able to mould a legal relationship without any use of language. Certainly, this concept may give rise to some doubts in relation to the attribution—to a behaviour qualified as mute—of the capability to affect dynamics involving a plurality of people. Aiming to clarify the idea of “mute behaviours” by this point of view, the authors analysed the (...) semiotic terminology used by Sacco himself to explain this notion and the issue of its silent nature. Therefore, the terms “signifying signs” and “symptoms”, deemed by Sacco—respectively—incompatible and compatible with the theory of mute behaviours were considered. The former term was traced back to the notion of conventional and arbitrary sign, the notion of the latter was reconstructed linking it to the concept of signs based on signification and suggesting a possible framework in view of the idea of “presentative meanings” developed by the philosopher Guido Morpurgo-Tagliabue. Clarified this dichotomy by a terminological analysis, the authors noticed—as affirmed by Rodolfo Sacco himself—the impossibility to ascribe the notion of gesture to the mute behaviour’s category, as some exegetes proposed. Consequently to this last remark, the authors tried to analyse the relationship between gestures and “mute behaviours”, identifying the category of “sema-pragmatic acts”, that includes gestures and may be seen as an intermediate phase between “mute behaviours” and legally relevant behaviours operated by speaking.

This is a draft of the introduction to the collective volume "The birth of string theory", including the book's index and preface. The book explores the history of the theory’s early stages of development, as told by its main protagonists. It journeys from the first version of the theory in the late 1960s, as an attempt to describe the physics of strong interactions outside the framework of quantum field theory, to its reinterpretation around the mid-1970s as a quantum theory of (...) gravity unified with the other interactions, and its successive developments up to the superstring revolution in 1984. The introductive Chapter summarizes the main developments and contains a chronological synopsis with a list of key results and publications. (shrink)

Implanting deep brain stimulation (DBS) electrodes in patients with Parkinson’s disease often results in the appearance of a non-infectious, delayed-onset edema that disappears over time. However, the time window between the DBS electrode and DBS stimulating device implant is often used to record local field potentials (LFPs) which are used both to better understand basal ganglia pathophysiology and to improve DBS therapy. In this work, we investigated whether the presence of post-surgery edema correlates with the quality of LFP recordings in (...) eight patients with advanced Parkinson’s disease implanted with subthalamic DBS electrodes. The magnetic resonance scans of the brain after 8.5 ± 1.5 days from the implantation surgery were segmented and the peri-electrode edema volume was calculated for both brain hemispheres. We found a correlation (ρ = −0.81, p < 0.0218, Spearman’s correlation coefficient) between left side local field potentials of the low beta band (11–20 Hz) and the edema volume of the same side. No other significant differences between the hemispheres were found. Despite the limited sample size, our results suggest that the effect on LFPs may be related to the edema localization, thus indicating a mechanism involving brain networks instead of a simple change in the electrode-tissue interface.

ArgumentEusapia Palladino (1854-1918) is remembered as one of the most famous mediums in the history of spiritualism. Renowned scientists attended her séances in Europe and in the United States. They often had to admit to being unable to understand the origin of the phenomena produced. Cesare Lombroso, for example, after meeting Eusapia, was converted first to mediumism, then spiritualism. This article will retrace the early stages of her career as a medium and shed light on the way she managed to (...) gain the attention of scientists. It will also show why they chose her as an epistemic object. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:“It’s not true, but I believe it”: Discussions on jettatura in Naples between the End of the Eighteenth and Beginning of the Nineteenth CenturiesFrancesco Paolo de CegliaIntroduction: What is Jettatura?Non èvero...ma ci credo (“It’s not true... but I believe it”) is the title of a comedy by the Italian actor and playwright, Peppino De Filippo, younger brother of the more famous Eduardo, which was staged for the (...) first time in 1942. The narrated events take place in the twentieth century and concern Gervasio Savastano, a Neapolitan businessman who is tormented by the fear of jettatura. The character, victim of grotesque events, first sacks a worker, believing him to be a jettatore, and then hires another, who is a hunchback and so should bring him good luck. In the end, however, it is discovered that the presumed jettatore has never harmed anyone and that the hunchback is not what he seems: he has stuffed his jacket in order to enter into the good graces of the gullible businessman and marry his daughter, with whom he has planned a con trick. The “lucky” events ascribed to his presence can therefore be considered casual. The epilogue? In keeping with the logic of compromise, typical of the brothers De Filippo’s theater, even though the character is rationally convinced of the unfounded nature of his beliefs, he remains adamant: “It’s not true, but I believe it” in other words.1 [End Page 75]“Where I come from, jettatura rules,” wrote the journalist and scriptwriter Giuseppe Marotta in 1947. Indeed, it is still a part of popular Neapolitan culture today.2 Often confused with similar beliefs, such as fascination (fascino) and the evil eye (malocchio), jettatura assumed its present form between the end of the eighteenth and beginning of the nineteenth century, at a time when a polite debate on its nature was taking shape in the city. In this period, the epistemological pluralism animating the discussions was translated into a variety of interpretative hypotheses and literary genres, in which grotesque atmospheres and spirited quips also found room, all perfectly in line with what could be considered the Weltanschauung of Savastano. It is the purpose of this article to examine these discussions, which even spread the term abroad and, with it, the “local color” of the concept.Nineteenth-century European writers on jettatura knew the Neapolitan authors well, and either quoted them explicitly or associated them with characters whose names were a deformation of real people’s: for example, Volitta for Valletta (Stendhal), don Jo (Stendhal) or Ojori (Dumas) for De Jorio. They explained that jettatura corresponded to the more familiar evil eye, but they left the term in Italian, as if to underline the fact that it was untranslatable.Is jettatura a mere anthropological issue, linked to a “primitive” culture, in the face of which official science would remain refractory? A belief that could not be exported or shared by those educated in more “highly developed” contexts? Well, in part, yes. Nevertheless, in the 1840s there was a visitor to Naples who expressed himself in the following terms: “When a foreigner arrives in Naples, at first he laughs at jettatura, then, little by little, he becomes troubled by it, and finally, after a stay of three months, you will see him covered in horns and with his right hand forever clenched [to ward off evil].”3 [End Page 76]So wrote the novelist Alexandre Dumas, père, one of the many travellers who, after having completed the Grand Tour of southern Italy, decided to describe its picturesque scenes and backward customs.4 Creating a veritable topos of travel literature, in the same period the philologist Karl August Mayer commented, “often foreigners let themselves be influenced” by local “superstitions.”5 Indeed many of them were captivated by these Neapolitan beliefs, despite their desire to remain objective and detached; and so they were “converted,” and driven to seek scientific explanations, often after meeting “a Real Jettatore,” whose image had nothing in common with the exotic fantasies of “a French Novelist’s Idea of Jettatore.”6Actually, Dumas and Mayer probably exaggerated somewhat in order to make their descriptions more...

Uberto Decembrio's Four Books on the Commonwealth (De re publica libri IV, ca. 1420), edited and translated by Paolo Ponzù Donato, is one of the earliest examples of the reception of Plato's Republic in the 15th century. This humanistic dialogue provides a thoughtful insight on themes such as justice, the best government, the morals of the prince and citizen, education, and religion. Decembrio's dialogue is dedicated to Filippo Maria Visconti, duke of Milan, the 'worst enemy' of Florence. Making (...) use of literary and documentary sources, Ponzù Donato convincingly proves that Decembrio's thought, sharing many points with the Florentine humanist Leonardo Bruni, belongs to the same world of Civic Humanism.

Paolo Mancosu provides an original investigation of historical and systematic aspects of the notions of abstraction and infinity and their interaction. A familiar way of introducing concepts in mathematics rests on so-called definitions by abstraction. An example of this is Hume's Principle, which introduces the concept of number by stating that two concepts have the same number if and only if the objects falling under each one of them can be put in one-one correspondence. This principle is at the (...) core of neo-logicism. In the first two chapters of the book, Mancosu provides a historical analysis of the mathematical uses and foundational discussion of definitions by abstraction up to Frege, Peano, and Russell. Chapter one shows that abstraction principles were quite widespread in the mathematical practice that preceded Frege's discussion of them and the second chapter provides the first contextual analysis of Frege's discussion of abstraction principles in section 64 of the Grundlagen. In the second part of the book, Mancosu discusses a novel approach to measuring the size of infinite sets known as the theory of numerosities and shows how this new development leads to deep mathematical, historical, and philosophical problems. The final chapter of the book explore how this theory of numerosities can be exploited to provide surprisingly novel perspectives on neo-logicism. (shrink)

The central hyperexcitability observed in animal models supports a pathophysiological explanation for chronic human pain. Novel information on cholecystokinin (CCK) upregulation offers a rationale for reduced opioid response in neuropathic pain. However, the basic information provided by scientists should not lead clinicians to equate experimental models to chronic human conditions. Clinicians should provide careful reports and attempt to classify pathophysiologically clinical conditions that have so far been grouped generically.

The contradictions between food poverty affecting a large section of the global population and the everyday wastage of food, particularly in high income countries, have raised significant academic and public attention. All actors in the food chain have a role to play in food waste prevention and reduction, including farmers, food manufacturers and processors, caterers and retailers and ultimately consumers. Food surplus redistribution is considered by many as a partial solution to food waste reduction and food poverty mitigation, while others (...) criticize charitable initiatives as inadequate responses, that inhibit governments from responsibly protecting the citizens right to food. This paper frames food assistance as “hybrid systems”, situating at the intersection of territorial food, public welfare and third sector voluntary systems. Based on available literature and reflections on previous research examining food banks in Italy, we develop a system dynamics conceptual mapping. The aim is to model a set of relations and dynamic mechanisms associated with variables relevant to food waste generation, food recovery for social purposes and food poverty alleviation. The analysis of feedback interactions highlights the vulnerabilities of food assistance systems that occur when addressing food poverty by reducing food surplus. In summary, as the awareness on food poverty and food surplus arises, incentives to food recovery and redistribution strengthen the role of food assistance actors, increasing their exposure to drivers of change, such as retailers’ standards for food surplus prevention. This paper contributes to the current academic debate on charitable food assistance, with insights for policy makers and other systems’ actors. (shrink)

Il volume si propone di sondare, a livelli diversi di profon­dità, alcuni problemiaperti dell’etica e della metaetica, intendendo tali termini in un senso assai lato. ‘Etica’ è infatti usato per riferirsi all’intero dominio del diritto, della politica e della mo­rale; ‘metaetica’ per riferirsi a qualunque discorso che verta sull’etica. Nella prima parte sono analizzati, a livello metaetico, alcuni concetti-chiave in ambito pratico: tra gli altri, quelli di tolleranza, di uguaglianza e di diritti umani. Nella seconda parte vengono affrontati, a livello (...) prevalentemente teorico, alcuni problemi cruciali del ragionamento giuridico, presentando soluzioni che, specie in tema di interpretazione, denunciano una chiara connotazione realista. Nella terza parte sono discussi criticamente, a livello metateorico, le tesi di alcuni eminenti filosofi del diritto contemporanei. (shrink)

An algebraization of the notion of topology has been proposed more than 70 years ago in a classical paper by McKinsey and Tarski, leading to an area of research still active today, with connections to algebra, geometry, logic and many applications, in particular, to modal logics. In McKinsey and Tarski’s setting the model theoretical notion of homomorphism does not correspond to the notion of continuity. We notice that the two notions correspond if instead we consider a preorder relation \( \sqsubseteq (...) \) defined by \(a \sqsubseteq b\) if _a_ is contained in the topological closure of _b_, for _a_, _b_ subsets of some topological space. A _specialization poset_ is a partially ordered set endowed with a further coarser preorder relation \( \sqsubseteq \). We show that every specialization poset can be embedded in the specialization poset naturally associated to some topological space, where the order relation corresponds to set-theoretical inclusion. Specialization semilattices are defined in an analogous way and the corresponding embedding theorem is proved. Specialization semilattices have the amalgamation property. Some basic topological facts and notions are recovered in this apparently very weak setting. The interest of these structures arises from the fact that they also occur in many rather disparate contexts, even far removed from topology. (shrink)

In the present paper we discuss a recent suggestion of Schroeder-Heister concerning the possibility of defining an intensional notion of harmony using isomorphism in second-order propositional logic. The latter is not an absolute notion, but its definition is relative to the choice of criteria for identity of proofs. In the paper, it is argued that in order to attain a satisfactory account of harmony, one has to consider a notion of identity stronger than the usual one (based on β- and (...) η-conversions) that the authors have investigated in recent work.

Recently, José María Ariso and Samuel Laves have critically debated whether killing innocent and non‐threatening people [=WK] is a universal moral certainty. One of the main topics of their discussion concerns the case of the pisa‐suaves, children born in the context of the Colombian civil war who grew up with the FARC guerrillas. While Laves argues that such children hold WK, Ariso rejects his claim and stresses that pisa‐suaves have no moral code of conduct. In my work, I side with (...) Laves and contend that WK is a universal moral certainty. Accordingly, I maintain that (i) either pisa‐suaves possess WK and thereby count as human moral agents, or (ii) if they do not possess any moral code of conduct, then they cannot count as human moral agents and, in turn, their existence does not undermine WK's universality.

On a popular view dating back to Russell, descriptions, both definite and indefinite alike, work syntactically and semantically like quantifiers. I have an argument against Russell's view. The argument supports a different picture: descriptions can behave syntactically and semantically like variables. This basic idea can be implemented in very different systematic analyses, but, whichever way one goes, there will be a significant departure from Russell. The claim that descriptions are variables is not new: what I offer is a new way (...) of defending it. The argument centers on attitude reports. I argue that we should recognize a new reading of descriptions under attitude reports, which I call ‘singular opaque’. The existence of this reading cannot be explained on the traditional Russellian view, and demands a switch to the variable view. Along the way, some interesting new facts about attitude reports come to light. (shrink)

The article examines reasons and features of the Italian bioethics movement in itself and in relationship to that in the U.S.A. Research, consultation, teaching are the most requested professional activities. Ethics committees are now established in several places and at different level: national (National Italian Committee for Bioethics), regional (Italy has about twenty regions with some political power), and institutional (research centers, university, main hospitals).

This paper deals with the relation between freedom and norm in the practical philosophy of Paul Ricoeur, taking into account especially the “Little Ethics” that covers Studies VII, VIII, IX of Oneself as Another. Although Ricoeur states the priority of ethics over moral, playing the quest for good and happiness off against deontological morality of duty, it soon appears clear that the norm is necessarily implied by the development of ethics itself. No actual freedom can exist without norm; but, on (...) the other and, no normative system is absolute, because the quest for good, in which freedom consists, cannot be fulfilled by any norm. This is the reason why it is always possible, and in some cases necessary, to act not following the established rules, but by improvisational conducts that can answer to the needs of the given situations. Aim of the article is to show the relevance of creativity for Ricoeur’s theory of action, but also to highlight the fact that creativity is not grounded on itself, but is linked to an infinite ethical ambition that give sense to improvisation.

El presente escrito se enmarca en un proyecto de investigación que propone abordar el complejo mundo del trabajo petrolero que se desarrolla en la Cuenca del Golfo San Jorge, en la Patagonia argentina, desde una perspectiva de género. La hipótesis de sentido que guía la investigación indica al universo hidrocarburífero de la región como un entretejido social sumamente heterogéneo. Dicha heterogeneidad se plasma también (quizás paradigmáticamente) en la participación femenina en el sector. A partir de entrevistas en profundidad, reconstruimos las (...) trayectorias laborales de mujeres vinculadas a la industria de los hidrocarburos en Comodoro Rivadavia.En una industria percibida como predominantemente masculina, no es fácil delimitar quiénes pueden entenderse como trabajadoras del petróleo, cuando el calificativo de “petroleros” suele reservarse a los varones. Para ello, en este texto compartimos los desafíos metodológicos de abordar el complejo petrolero en búsqueda de sus trabajadoras. Así, presentamos dilemas, reflexiones y hallazgos de un trabajo de campo atravesado por la reflexividad. Identificar a esas mujeres, caracterizar sus trabajos, prácticas y desplazamientos conllevó reconocer nuestras propias posiciones en el espacio social.Se indican tres perfiles típicos hallados entre nuestras entrevistadas para interrogar sobre su representatividad y provisoriedad, en tanto el análisis en profundidad nos orienta a la identificación de rasgos comunes entre aquellas que en un principio parecen muy diferentes.

The two theories of pancreatic enzyme secretion, those of exocytosis and transmembrane flow, are described. Data thought to support the theory of transmembrane flow of single molecules from pancreatic acinar cells are first reviewed, and the conditions which could allow these data to be explained by the theory of exocytosis of enzyme quanta, i.e. secretory granules, are then discussed.The evidence suggesting short‐term modulation of the composition of pancreatic juice is also considered, and its possible explanations at the organ and cellular (...) level are discussed, in the light of suggested theories on enzyme secretion pathways.

In the last decades, Systems Biology (including cancer research) has been driven by technology, statistical modelling and bioinformatics. In this paper we try to bring biological and philosophical thinking back. We thus aim at making diferent traditions of thought compatible: (a) causality in epidemiology and in philosophical theorizing—notably, the “sufcient-component-cause framework” and the “mark transmission” approach; (b) new acquisitions about disease pathogenesis, e.g. the “branched model” in cancer, and the role of biomarkers in this process; (c) the burgeoning of omics (...) research, with a large number of “signals” and of associations that need to be interpreted. In the paper we summarize frst the current views on carcinogenesis, and then explore the relevance of current philosophical interpretations of “cancer causes”. We try to ofer a unifying framework to incorporate biomarkers and omic data into causal models, referring to a position called “evidential pluralism”. According to this view, causal reasoning is based on both “evidence of diference-making” (e.g. associations) and on “evidence of underlying biological mechanisms”. We conceptualize the way scientists detect and trace signals in terms of information transmission, which is a generalization of the mark transmission theory developed by philosopher Wesley Salmon. Our approach is capable of helping us conceptualize how heterogeneous factors such as micro and macro-biological and psycho-social—are causally linked. This is important not only to understand cancer etiology, but also to design public health policies that target the right causal factors at the macro-level. (shrink)

Exploring the metaphysics of deep disagreements, Ranalli identifies several essential features shared by all such disputes. These very features constitute a set of adequacy conditions that any satisfactory theory of deep disagreements must meet. The paper explains how Coliva’s Wittgensteinian hinge theory can satisfy Ranalli’s persistence desideratum. According to this condition, any appropriate theory must explain why deep disagreements tend to be persistent and thus unresolved without presupposing that they are rationally irresolvable. First, the work critically discusses how Coliva utilizes (...) her proposed view to account for this desideratum. Second, the paper points out that Coliva’s response is partly problematic because of Ranalli’s definition of deep disagreements for Wittgensteinian hinge theories, which over-generates instances of genuine deep disagreements. Third, the work argues that Coliva’s theory can satisfy Ranalli’s persistence desideratum by resolving a deep disagreement between an anti-vaccination advocate and a proponent of vaccination using an expanded version of Pritchard’s side-on approach. Finally, the paper critically engages with Coliva on the solvability of deep disagreements. (shrink)

This article responds to the arguments put forth by Peter Lamarque and Stein Haugom Olsen in Truth, Fiction, and Literature: A Philosophical Perspective (1994). It argues that the said work is representative of the widespread tendency in literary theory today to discard the possibility of literary truth, and it provides counterarguments to the work’s main theses. Consequently, it criticizes the philosophy of pragmatism and its implications, and it offers a theory that defines fictional objects as existing and solves contradictions that (...) commonly affect our debates on the ontology of fiction. The article does not provide a positive theory of literary truth, but it undermines its denials, which have become popular in recent decades. (shrink)

This paper investigates whether, and if so, in what way, argumentation can be profitably described in speech-act theoretical terms. I suggest that the two theories of argumentation that are supposed to provide the most elaborate analysis of it in speech-act theoretical terms (namely van Eemeren and Rob Grootendorst’s Pragma-Dialectics and Lilian Bermejo-Luque’s linguistic normative model of argumentation) both suffer from the same two flaws: firstly, their “illocutionary act pluralism” assumption and secondly, a lack of interest in where arguing belongs in (...) the classification of illocutionary acts. I argue that these flaws derive from the authors’ reliance on an intention-based speech-theoretical framework. Finally, I adopt a deontic framework for speech acts in order to propose an alternative way of accounting for argumentation which seems to overcome the two limitations outlined above. According to this framework, argumentation may be conceived as a speech act sequence, characterized by the conventional effects brought about by the communicative moves (as illocutionary acts) of which it is composed.

We introduce a deductive system Bal which models the logic of balance of opposing forces or of balance between conflicting evidence or influences. ‘‘Truth values’’ are interpreted as deviations from a state of equilibrium, so in this sense, the theorems of Bal are to be interpreted as balanced statements, for which reason there is only one distinguished truth value, namely the one that represents equilibrium. The main results are that the system Bal is algebraizable in the sense of [5] and (...) its equivalent algebraic semantics BAL is definitionally equivalent to the variety of abelian lattice ordered groups, that is, the categories of the algebras in BAL and of ℓ–groups are isomorphic (see [10], Ch.4, 4). We also prove the deduction theorem for Bal and we study different kinds of semantic consequence associated to Bal. Finally, we prove the co-NP-completeness of the tautology problem of Bal. (shrink)
