How are abstract concepts and musical themes recognized on the basis of some previous experience? It is interesting to compare the different behaviors of human and of artificial intelligences with respect to this problem. Generally, a human mind that abstracts a concept (say, table) from a given set of known examples creates a table-Gestalt: a kind of vague and out of focus image that does not fully correspond to a particular table with well determined features. A similar situation arises in (...) the case of musical themes. Can the construction of a gestaltic pattern, which is so natural for human minds, be taught to an intelligent machine? This problem can be successfully discussed in the framework of a quantum approach to pattern recognition and to machine learning. The basic idea is replacing classical data sets with quantum data sets, where either objects or musical themes can be formally represented as pieces of quantum information, involving the uncertainties and the ambiguities that characterize the quantum world. In this framework, the intuitive concept of Gestalt can be simulated by the mathematical concept of positive centroid of a given quantum data set. Accordingly, the crucial problem “how can we classify a new object or a new musical theme (we have listened to) on the basis of a previous experience?” can be dealt with in terms of some special quantum similarity-relations. Although recognition procedures are different for human and for artificial intelligences, there is a common method of “facing the problems” that seems to work in both cases. (shrink)

En este artículo buscamos indagar el sentido y alcance de unos términos que se entrelazan en las acciones y modos de relacionarnos en un medio, no sólo existencial, sino social. Centraremos el enfoque a partir de la lectura de algunos textos de Merleau-Ponty para presentar así su peculiar modo de abordar ciertos temas desde una perspectiva fenomenológica situada. Palabras clave: corporalidad; interioridad; exterioridad; conciencia; fenomenología. The Corporality of the Self and the Interiority of the Other, in Merlau-Ponty’s philosophyIn this paper (...) we inquire into the sense and scope of terms which are intertwined in the actions and ways in which we relate to one another, in a medium which is not only existential, but social as well. We shall focus on the reading of some texts of Merleau-Ponty, in order to show his peculiar way of addressing certain topics from a situated phenomenological perspective.

Riassunto: L’indagine sui fondamenti neurali del giudizio morale è uno dei principali ed attuali temi di ricerca della Neuroscienza, il quale si intreccia inevitabilmente con tematiche relative all’Intelligenza Artificiale, al futuro dei trasporti e alla Filosofia della Mente. Gli esseri umani sono naturalmente dotati di un innato senso della morale, il quale è governato dalle intuizioni, ma sono anche provvisti di alcuni principi razionali. Il giudizio e il comportamento morale sono il risultato dell’integrazione fra le emozioni e i processi razionali, (...) proprio come i processi cognitivi erano una combinazione di istinto e pura computazione. Nella parte finale di questo lavoro, ho preso in considerazione i problemi di natura morale derivanti dall’introduzione dei veicoli a guida autonoma, i quali si presentano come un’applicazione diretta del problema del carrello : come dovrebbe essere programmato un veicolo per comportarsi nel caso di un incidente inevitabile, nel quale deve scegliere tra due mali? Parole chiave: Processi decisionali; Neuroscienza; Giudizi morali; Prospettiva comparata; Problema del carrello Brains and Trolleys: Formalizing Morality in Automated Driving Cars: Inquiry into the neural bases of moral judgment is one of the current frontiers in neuroscientific research and is intertwined with issues in Artificial Intelligence, the future of transport, and Philosophy of Mind. Humans are naturally endowed with an innate moral sense, which is governed by intuition and informed by rational rules. Moral judgment and behavior are the byproduct of the integration of emotional and rational processes, just as cognitive processes are the result of a combination of emotional instinct and computational rationality. In the latter part of this work, I also consider the ethical issues raised by the introduction of Automated Driving Systems by reexamining the Trolley Problem : how should an autonomous vehicle be programmed to behave in the event of an unavoidable accident, in which it has to choose between two harmful consequences harms? Keywords: Decision-making; Neuroscience; Moral Judgments; Comparative Perspective; Trolley Problem. (shrink)

The coronavirus disease 2019 pandemic has strongly affected oncology patients. Many screening and treatment programs have been postponed or canceled, and such patients also experience fear of increased risk of exposure to the virus. In many cases, locus of control, coping flexibility, and perception of a supportive environment, specifically family resilience, can allow for positive emotional outcomes for individuals managing complex health conditions like cancer. This study aims to determine if family resilience, coping flexibility, and locus of control can mitigate (...) the negative affect caused by the pandemic and enhance positive affect in breast cancer patients. One hundred and fifty-four female patients with breast cancer completed the Walsh’s Family Resilience Questionnaire, the Perceived Ability to Cope With Trauma Scale, the Positive-Negative Affect Schedule, and the Mini Locus of Control Scale. Family resilience and internality of locus of control contribute significantly to positive affective responses. Family resilience is responsible for mitigating the negative affect perceived during the pandemic and is enhanced by external locus of control. Evidence suggests that clinical psychologists should develop and propose programs to support oncology patients’ family resilience, coping flexibility, and internal locus of control, allowing for decreased stress and improved adaptability for effectively managing cancer treatment during the pandemic.

Este artigo intenta apresentar como a pregação de Santo António de Pádua está conectada com a cidade. Através de alguns exemplos tomados das legendas hagiográficas e sermões, o autor reconstrói as mudanças de atitudes de hagiógrafos e pregadores ligados a António algumas vezes a um contexto urbano geral e, em última medida, a cidade de Pádua. Em particular, o artigo se detém sobre alguns textos que destacam o efeito da pregação de Santo António no seu público-alvo, ou seja, a população (...) da cidade em que falava. O período da análise é primariamente compreendido durante a canonização do santo, em meados do século XIV. Apesar disso, algumas referências a autores da época posterior serão feitas como comparação e aprofundamento da panorâmica oferecida. No final da Idade Média, santo António acabaria por ser, em certa medida, o modelo para os frades mendicantes, talvez atraídos pelos santos mais próximos no tempo. (shrink)

The communicative affordances of the participatory web have opened up new and multifarious channels for the proliferation of hate. In particular, women navigating the cybersphere seem to be the target of a disproportionate amount of hostility. This paper explores the contexts, approaches and conceptual synergies around research on online misogyny within the new communicative paradigm of social media communication. The paper builds on the core principle that online misogyny is demonstrably and inherently a discourse; therefore, the field is envisaged at (...) the intersection of digital media scholarship, discourse theorization and critical feminist explications. As an ever-burgeoning phenomenon, online hate has been approached from a range of disciplinary perspectives but has only been partially mapped at the interface of meaning making contents/processes and new mediation technologies. The paper aims to advance the state of the art by investigating online hate in general, and misogyny in particular, from the vantage point of Social Media Critical Discourse Studies ; an emerging model of theorization and operationalization of research combining tenets from Critical Discourse Studies with scholarship in digital media and technology research. Our SM-CDS approach to online misogyny demarcates itself from insinuation whereby the phenomenon is reduced to digital communicative affordances per se and argues in favor of a double critical contextualization of research findings at both digital participatory as well as social and cultural levels.

The paper explores the interplay among moral progress, evolution and moral realism. Although it is nearly uncontroversial to note that morality makes progress of one sort or another, it is far from uncontroversial to define what constitutes moral progress. In a minimal sense, moral progress occurs when a subsequent state of affairs is better than a preceding one. Moral realists conceive “it is better than” as something like “it more adequately reflects moral facts”; therefore, on a realist view, moral progress (...) can be associated with accumulations of moral knowledge. From an evolutionary perspective, on the contrary, since there cannot be something like moral knowledge, one might conclude there cannot even be such a thing as moral progress. More precisely, evolutionism urges us to ask whether we can acknowledge the existence of moral progress without being committed to moral realism. A promising strategy, I will argue, is to develop an account of moral progress based on moral understanding rather than moral knowledge. On this view, moral progress follows increases in moral understanding rather than accumulations of moral knowledge. Whether an understanding-based account of moral progress is feasible and what its implications for the notion itself of moral progress are, will be discussed. (shrink)

The aim of this article is to explore the impact of Darwinism in metaethics and dispel some of the confusion surrounding it. While the prospects for a Darwinian metaethics appear to be improving, some underlying epistemological issues remain unclear. We will focus on the so-called Evolutionary Debunking Arguments (EDAs) which, when applied in metaethics, are defined as arguments that appeal to the evolutionary origins of moral beliefs so as to undermine their epistemic justification. The point is that an epistemic disanalogy (...) can be identified in the debate on EDAs between moral beliefs and other kinds of beliefs, insofar as only the former are regarded as vulnerable to EDAs. First, we will analyze some significant debunking positions in metaethics in order to show that they do not provide adequate justification for such an epistemic disanalogy. Then, we will assess whether they can avoid the accusation of being epistemically incoherent by adopting the same evolutionary account for all kinds of beliefs. In other words, once it is argued that Darwinism has a corrosive impact on metaethics, what if its universal acid cannot be contained? (shrink)

The two dominant theories relating to animal cruelty are critically reviewed. These are (1) the violence graduation hypothesis and (2) the deviance generalization hypothesis. The outcomes indicate very high consistency with the broader antisocial behavior and aggression literature, which is large and very robust. This strongly supports the validity of the animal cruelty theory proposals. Proposals that animal cruelty is one of the earliest indicators of externalizing disorders and that it is a marker of development along a more severe trajectory (...) of antisocial and aggressive behaviors are supported. The implications of these conclusions are discussed. (shrink)

Four men in a cell in Rebibbia prison, Rome, awaiting trial on serious charges of subversion. One of them, the political thinker Antonio Negri, spends his days writing. Among his writings are twenty letters addressed to a young friend in France Ð letters in which Negri reflects on his own personal development as a philosopher, theorist and political activist and analyses the events, activities and movements in which he has been involved. The letters recount an existential journey that (...) links a rigorous philosophical education with a powerful political passion, set against the historical backdrop of postwar Italy. Crucially, Negri recalls the pivotal moment in 1978 when the former prime minister of Italy, Aldo Moro, was kidnapped and killed by the Red Brigades, and how the institutions then pinned that killing onto him and his associates. Published here for the first time, these letters offer a unique and invaluable insight into the factors that shaped the thinking of one of the most influential political theorists of our time and they document Negri’s role in the development of political movements like Autonomia. They are a vivid testimony to one man’s journey through the political upheavals and intellectual traditions of the late 20th century, in the course of which he produced a body of work that has had, and continues to have, a profound impact on radical thought and politics around the world.

Some propositions are structurally unknowable for certain agents. Let me call them ‘Moorean propositions’. The structural unknowability of Moorean propositions is normally taken to pave the way towards proving a familiar paradox from epistemic logic—the so-called ‘Knowability Paradox’, or ‘Fitch’s Paradox’—which purports to show that if all truths are knowable, then all truths are in fact known. The present paper explores how to translate Moorean statements into a probabilistic language. A successful translation should enable us to derive a version of (...) Fitch’s Paradox in a probabilistic setting. I offer a suitable schematic form for probabilistic Moorean propositions, as well as a concomitant proof of a probabilistic Knowability Paradox. Moreover, I argue that traditional candidates to play the role of probabilistic Moorean propositions will not do. In particular, we can show that violations of the so-called ‘Reflection Principle’ in probability need not yield structurally unknowable propositions. Among other things, this should lead us to question whether violating the Reflection Principle actually amounts to a clear case of epistemic irrationality, as it is often assumed. This result challenges the importance of the principle as a tool to assess both synchronic and diachronic rationality—a topic which is largely independent of Fitch’s Paradox—from a somewhat unexpected source.

This book investigates the relationship between our present and future selves. It focuses specifically on diachronic self-regarding decisions: choices involving our earlier and later selves, in which the earlier self makes a decision for the later self. The author connects the scientific understanding of the neurobehavioral processes at the core of individuals' perceptions of their future selves with the philosophical reflection on individuals' moral relationship with their future selves. She delineates a descriptive theory of the perception of the future self (...) that is based on empirical evidence and that systematizes and integrates the current theoretical literature. She then argues for the morality of prudence and interprets diachronic self-regarding decisions as decisions between two agents-the earlier and later selves-that belong to the realm of intergenerational ethics, which regulates the relationship between contemporary people and future generations. Finally, the author provides a moral theory of prudence based on respect for one's agency. This theory identifies what the present and the future selves owe to one another in diachronic self-regarding decisions. Moral Choices for Our Future Selves will be of interest to researchers and students working in ethics, moral psychology, philosophy of mind, and cognitive science. (shrink)

Large portions of mathematics such as algebra and geometry can be formalized using first-order axiomatizations. In many cases it is even possible to use a very well-behaved class of first-order axioms, namely, what are called coherent or geometric implications. Such class of axioms can be translated to inference rules that can be added to a sequent calculus while preserving its structural properties. In this work, this fundamental result is extended to their infinitary generalizations as extensions of sequent calculi for both (...) classical and intuitionistic infinitary logic. As an application, a simple proof of the infinitary Barr’s theorem without the axioms of choice is shown. (shrink)

Kan demokrati - folkets magt - realiseres. Forfatteren gennemgår dette på baggrund af den konflikt, der altid har været mellem den påtvungne magt og den valgte magt.

A general method for generating contraction- and cut-free sequent calculi for a large family of normal modal logics is presented. The method covers all modal logics characterized by Kripke frames determined by universal or geometric properties and it can be extended to treat also Gödel-Löb provability logic. The calculi provide direct decision methods through terminating proof search. Syntactic proofs of modal undefinability results are obtained in the form of conservativity theorems.

This book continues from where the authors' previous book, Structural Proof Theory, ended. It presents an extension of the methods of analysis of proofs in pure logic to elementary axiomatic systems and to what is known as philosophical logic. A self-contained brief introduction to the proof theory of pure logic is included that serves both the mathematically and philosophically oriented reader. The method is built up gradually, with examples drawn from theories of order, lattice theory and elementary geometry. The aim (...) is, in each of the examples, to help the reader grasp the combinatorial behaviour of an axiom system, which typically leads to decidability results. The last part presents, as an application and extension of all that precedes it, a proof-theoretical approach to the Kripke semantics of modal and related logics, with a great number of new results, providing essential reading for mathematical and philosophical logicians.

Antonio Negri wrote the two essays that comprise Time for Revolution while serving a prison sentence for alleged involvement with radical left-wing groups. Although the essays were written two decades apart, their concerns are the same: is there a place for resistance in a society utterly subsumed by capitalism?

In this paper I am concerned with the problem of applying the notion of rigidity to general terms. In Naming and Necessity, Kripke has clearly suggested that we should include some general terms among the rigid ones, namely, those common nouns semantically correlated with natural substances, species and phenomena, in general, natural kinds -'water', 'tiger', 'heat'- and some adjectives -'red', 'hot', 'loud'. However, the notion of rigidity has been defined for singular terms; after all, the notion that Kripke has provided (...) us with is the notion of a rigid designator. But general terms do not designate single individuals: rather, they apply to many of them. In sum, the original concept of rigidity cannot be straightforwardly applied to general terms: it has to be somehow redefined in order to make it cover them. As is known, two main positions have been put forward to accomplish that task: the identity of designation conception, according to which a rigid general term is one that designates the same property or kind in all possible worlds, and the essentialist conception, which conceives of a rigid general term as an essentialist one, namely, a term that expresses an essential property of an object. My purpose in the present paper is to defend a particular version of the identity of designation conception: on the proposed approach, a rigid general term will be one that expresses the same property in all possible worlds and names the property it expresses. In my opinion, the position can be established on the basis of an inference to the best explanation of our intuitive interpretation and evaluation, relative to counterfactual circumstances, of statements containing different kinds of general terms, which is strictly analogous to our intuitive interpretation and evaluation, relative to such circumstances, of statements containing different kinds of singular ones. I will argue that it is possible to offer a new solution to the trivialization problem that is thought to threaten all versions of the identity of designation conception of rigidity. Finally, I will also sketch a solution to the so-called 'over-generalization and under-generalization problems', both closely related to the above-mentioned one. (shrink)

Epistemic transparency tells us that, if an agent S knows a given proposition p , then S knows that she knows that p . This idea is usually encoded in the so-called KK principle of epistemic logic. The paper develops an argument in favor of a moderate version of KK , which I dub quasi-transparency , as a normative rather than a descriptive principle. In the second Section I put forward the suggestion that epistemic transparency is not a demand of (...) ideal rationality, but of ideal epistemic responsibility, and hence that ideally responsible agents verify transparency principles of some sort; I also contend that their satisfaction should not be tied to an internalist epistemology. The central argument in favor of transparency is then addressed in Sections 3 to 8, through the development of a formal system. I show that, in a well-behaved formal setting, a moderate version of transparency is imposed upon us as a result of a number of independent decisions on the structure of higher-order probabilities, as long as we request that our probability and knowledge attributions cohere with each other. Thus I give a rationale to build a model for a hierarchy of languages with different levels of knowledge and probability operators; we obtain an analogous to KK for successive knowledge operators without actually demanding transitivity. The formal argument reinforces the philosophical intuition that epistemic transparency is an important desideratum we should not be too ready to dismiss. (shrink)

The work examines the influence of the relationship that football players have with significant others on their psychological wellbeing (PWB), adopting a psychosocial perspective. According to this perspective, PWB can be considered a basic condition for an effective talent development and holistic growth of young athletes. Current literature on talent development in sport has been analyzed to support the theoretical hypothesis of psychosocial perspective. Thus, it has been tested empirically through a Structural Equation Model. Analysis reveals a strong and positive (...) influence of some dimensions of the relationships with significant others on the psychological wellbeing, specifically team effort, coach closeness and parental learning climate. Following ANOVA shows that élite players perceive significantly better relationships than sub-élite and amateurs and have significantly higher levels of PWB. Those results provide a first evidence for the importance of relationships within and outside sport for an effective talent development, since they positively influence players’ PWB, that is higher in higher competitive level players. It emerges the necessity to further investigate different aspects of psychological wellbeing and to deepen the knowledge about the meaning of relationship in developmental athletes according to a psychosocial approach.

Alexithymic traits, which entail finding it difficult to recognize and describe one’s own emotions, are linked with poor trait emotional intelligence and difficulties in identifying and managing stressors. There is evidence that alexithymia may have detrimental consequences for wellbeing and health, beginning in adolescence. In this cross-sectional study, we investigated the prevalence and incidence of alexithymia in teenage girls, testing the statistical power of TEI and student burnout to discriminate between high- and low-alexithymic subjects. A sample of 884 female high (...) school students attending three Italian academic-track high schools completed self-report measures of alexithymia, school burnout, and TEI. Main descriptive statistics and correlational analysis preceded the discriminant analysis. The mean alexithymia scores suggest a high prevalence of alexithymia in female adolescents; as expected, this trait was negatively correlated with TEI and positively associated with school burnout. Participants with high vs. low alexithymia profiles were discriminated by a combination of TEI and burnout scores. High scores for the emotionality and self-control dimensions of TEI were strongly associated with membership of the low alexithymia group; high scores for the emotional exhaustion dimension of school burnout were indicative of membership of the high alexithymia group. These findings suggest crucial focuses for educational intervention: efforts to reduce the risk of emotional exhaustion and school burnout should especially concentrate on enhancing emotional awareness and self-control skills, both strongly associated with low levels of alexithymia.

Risk management is a well-known method to face technological challenges through a win–win combination of protective and proactive approaches, fostering the collaboration of operators, researchers, regulators, and industries for the exploitation of new markets.

The paper aims to expand this approach with a tool (...) for managing data protection risks raised by drones through the design of flight maps. The tool should allow UAS operators choosing the best air corridor for their drones based on the so-called privacy by design principle pursuant to Article 25 of the EU data protection regulation, the GDPR.

In this paper I question Penelas' claim that the debate on the model-theoretic argument -proposed by Putnam and rejected by causal theorists such as Devitt- has reached the stage of a methodological impasse: the semantic issue cannot be settled until a wider issue concerning the methodology of the philosophical research is itself settled. My thesis is that both Putnam and Devitt has known the debate to be not merely semantic but mainly methodological ali along. Moreover, I try to make the (...) further point that the argumentative strategy chosen by Putnam has a circularity problem. (shrink)

Antonio Negri, one of the world's leading scholars on Baruch Spinoza (1632-1677) and his contemporary legacy, offers a straightforward explanation of the philosopher's elaborate arguments and a persuasive case for his ongoing relevance. Responding to a resurgent interest in Spinoza's thought and its potential application to contemporary global issues, Negri demonstrates the thinker's special value to politics, philosophy, and related disciplines. Negri's work is both a return to and an advancement of his initial affirmation of Spinozian thought (...) in _The Savage Anomaly_. He further defends his understanding of the philosopher as a proto-postmodernist, or a thinker who is just now, with the advent of the postmodern, becoming contemporary. Negri also connects Spinoza's theories to recent trends in political philosophy, particularly the reengagement with Carl Schmitt's "political theology," and the history of philosophy, including the argument that Spinoza belongs to a "radical enlightenment." By positioning Spinoza as a contemporary revolutionary intellectual, Negri addresses and effectively defeats twentieth-century critiques of the thinker waged by Jacques Derrida, Alain Badiou, and Giorgio Agamben.

The paper suggests a way of modeling belief changes within the tradition of formal belief revision theories. The present model extends the scope of traditional proposals, such as AGM, so as to take care of “structural belief changes” – a type of radical shifts that is best illustrated with, but not limited to, instances of scientific discovery; we obtain AGM expansions and contractions as limiting cases. The representation strategy relies on a non-standard use of a semantic machinery. More precisely, the (...) model seeks to correlate knowledge states with interpretations of a given formal language L, in such a way that the epistemic state of an agent at a given time gives rise to a picture of how things could be, if there weren’t anything else to know. Interpretations of L proceed along supervaluational ideas; hence, the model as a whole can be seen as a particular application of supervaluational semantics to epistemic matters. (shrink)

In a recent paper Samir Okasha has suggested an application of Arrow’s impossibility theorem to theory choice. When epistemic virtues are interpreted as ‘voters’ in charge of ranking competing theories, and there are more than two theories at stake, the final ordering is bound to coincide with the one proposed by one of the voters, provided a number of seemingly reasonable conditions are in place. In a similar spirit, Jacob Stegenga has shown that Arrow’s theorem applies to the amalgamation of (...) evidence; the ‘voters’ here are the different sources of evidence. As with Okasha’s proposal, it is not clear how to avoid Arrow’s pessimistic conclusion.In this paper we develop a novel argument that purports to show that, in typical examples, Arrow’s result does not obtain when dealing with evidence amalgamation. The reason is that we cannot escape the well-known Duhem problem: the evidence actually confirms complex conjunctions that include various auxiliary hypotheses. We argue that confirmational holism induces us to restrict the domain of a reasonable amalgamation function, thus violating one of Arrow’s conditions. The upshot is that we are now able to see the Duhem problem under a different, positive light – namely, as a phenomenon that makes the aggregation of the evidence possible in the first place, when there are at least three options on the table.

This article focuses on the animal cruelty, health, psychological and social consequences, as well as environmental consequences of an animal-based diet. Animals are intensively bred and raised in factory farms in the most inhumane ways. By far, the greatest numbers of animals reared and killed by humans every year is for human consumption. The numbers are estimated to be greater than 56 billion animals globally. The cruelty involved in the intensive farming of animals is the most widespread form of cruelty (...) imposed by humans on other species. This has significant implications for who we are as a species. Moreover, the belief that humans need to consume animal products to maintain good health has been seriously questioned over the past few decades. It is also a lifestyle choice that is responsible for significant damage to the environment. In contrast, a strong evidence base exists to show that a plant-based diet is health promoting and sustainable. Thus, by cultivating a culture of compassion toward nonhuman animals, current and future generations will benefit through better physical and psychological health and through markedly reduced damage to the planet and all of its inhabitants.

This article investigates three major contexts in which Henry of Ghent’s Summa quaestionum ordinariarum was received from the thirteenth to the fifteenth century. The study takes into account the material features of a group of relevant manuscripts of the Summa: Paris, where the Summa was copied and annotated by Godfrey of Fontaines and his socii; the Dominican convent in Bologna at the beginning of the fourteenth century, to which Aimericus de Placentia gave a copy of the Summa corrected against the (...) very manuscript of Godfrey of Fontaines; the Roman Papal Court, where the Summa attracted the special attention of the humanist Pope Nicholas V, who employed the manuscript from the Bolognese convent for producing new copies of the work.

This paper is centered on the semantic theory of truth, formulated by Alfred Tarski. According to some authors, this theory is to be construed as a contemporary version of the traditional correspondence theory, namely, the one that defines truth as the correspondence between language and the world. In contrast, there are others who think that Tarki´s theory reveals a deflationary conception of truth, according to which truth can be reduced to a linguistic resource for semantic ascent. Since I agree with (...) the last group, I set out to support a special version ─the so-called “semanticalist version” ─ of the deflationary interpretation of the semantic theory. In the first section, I characterize the two alternative conceptions of truth above mentioned, that is, correspondence and deflationism. The second section contains and exposition of the modal argument, wich takes the Tarskian theory to inspire a syntacticalist version of the deflationary conception. In the third section, I criticize the argument in question and attempt to ground the above mentioned wide, semanticalist interpretation of deflationism. (shrink)
