In this paper we prove strong completeness of axiomatic extensions of first-order strict core fuzzy logics with the so-called quasi-witnessed axioms with respect to quasi-witnessed models. As a consequence we obtain strong completeness of Product Predicate Logic with respect to quasi-witnessed models, already proven by M.C. Laskowski and S. Malekpour in [19]. Finally we study similar problems for expansions with Δ, define Δ-quasi-witnessed axioms and prove that any axiomatic extension of a first-order strict core fuzzy logic, expanded with Δ, and (...) Δ-quasi-witnessed axioms are complete with respect to Δ-quasi-witnessed models. (shrink)

In the substitutional framework, validity is truth under all substitutions of the nonlogical vocabulary. I develop a theory where □ is interpreted as substitutional validity. I show how to prove soundness and completeness for common modal calculi using this definition.

La question de la temporalité est l’un des aspects les moins étudiés de la pensée de Patočka et elle est très peu discutée dans les débats internationaux concernant ses travaux. Cependant, elle revêt une importance décisive, car elle prépare son projet de phénoménologie asubjective. Cet article se concentre sur le cheminement qui mène à cette conception : il identifie les éléments théoriques et les conséquences asubjectives de l’analyse que le phénoménologue tchèque propose des Leçons pour une phénoménologie de la conscience (...) intime du temps de Husserl. Le temps n’est plus considéré comme l’unité du flux subjectif constitué par la rétention, mais il est compris comme l’ajointement primordial du champ d’apparaître dans sa structure « déjà » unifiée d’espace-temps-qualités. Le fondement de la structure du temps ne peut donc plus être le présent vivant du sujet et son champ de présence. L’aboutissement de ce parcours critique, qui n’est pas analysé ici, nous confirme que la temporalité fait référence aux lois de l’apparaître et reste un enjeu central, car elle agit sur notre compréhension du monde et sur la relation sujet-monde dans l’histoire.

Even though he is mainly known for his concept of constituent power, Sieyès was one of the first constitutional theorists to ask for a guardian of the constitution which closely resembles contemporary constitutional courts. This article reconstructs the main tenets of his proposal, puts them in the larger context of his constitutional theory and then assesses the constitutional nature and functions of this institution. The judgment is mixed: as an organ, Sieyès’ constitutional jury is a hybrid institution, neither a real (...) third chamber nor a full-fledged constitutional court; however, its functions not only are a clear anticipation of the control of constitutionality, but are also intended to tame constituent power and to protect the rights of man in case of legal gaps.

Nel suo pionieristico lavoro Conditions in Königsberg and the Making of Kant's Philosophy, Giorgio Tonelli lamentava l'assenza di un'indagine approfondita sul contesto intellettuale di Königsberg e sull'eventuale influenza che esso esercitò su alcuni aspetti del pensiero di Kant. Questo libro vuole colmare questa lacuna prestando particolare attenzione alla tradizione aristotelica, alla Schulphilosophie, e alla corrente dell'eclettismo, che dominarono l'ambiente regiomontano sino all'avvento della filosofia critica kantiana. Il lavoro mostra come dai fallimenti dei progetti logici e metafisici precritici, legati alle influenze (...) ricevute dall'ambiente di Königsberg, Kant abbia tratto le idee e gli spunti per la stesura della Kritik der reinen Vernunft.

According to the received view, reduction is a deductive relation between two formal theories. In this paper, I develop an alternative approach, according to which reduction is a representational relation between models, rather than a deductive relation between theories; more specifically, I maintain that this representational relation is the one of emulation. To support this thesis, I focus attention on mathematical dynamical systems and I argue that, as far as these systems are concerned, the emulation relation is sufficient for reduction. (...) I then extend this representational model-based view of reduction to the case of empirically interpreted dynamical systems, as well as to a treatment of partial, approximate, and asymptotic reduction.

Integrity is often conceived as a moral virtue that pertains to the coherence between one’s moral convictions and actions, as well as consistency in convictions over time. By contrast, I argue that integrity is primarily an epistemic virtue. To act with integrity, an individual or organisation must engage in responsible inquiry; that is, the collection, processing, sharing, and storage of information in ways that promote truth. Organisational structures such as division of labour and hierarchy present challenges to responsible inquiry, thereby (...) making epistemic integrity in organisations inherently vulnerable and increasing the risk of unintentional unethical behaviour. This epistemic perspective on organisational integrity emphasises the importance of developing virtuous epistemic infrastructure and an ethical epistemic culture. By aligning their beliefs with facts, organisations can also improve moral behaviour and reduce the risk of culpable ignorance. (shrink)

This article describes well quasi orders as a category, focusing on limits and colimits. In particular, while quasi orders with monotone maps form a category which is finitely complete, finitely cocomplete, and with exponentiation, the full subcategory of well quasi orders is finitely complete and cocomplete, but with no exponentiation. It is interesting to notice how finite antichains and finite proper descending chains interact to induce this structure in the category: in fact, the full subcategory of quasi orders with finite (...) antichains has finite colimits but no products, while the full subcategory of well founded quasi orders has finite limits but no coequalisers. Moreover, the article characterises when exponential objects exist in the category of well quasi orders and well founded quasi orders. This completes the systematic description of the fundamental constructions in the categories of quasi orders, well founded quasi orders, quasi orders with finite antichains, and well quasi orders.

Volgendo l’attenzione alla problematica traduzione del cosiddetto basilicus iactus menzionato nella commedia Curculio di Plauto questo articolo cerca di fornire un nuovo contributo allo studio della cultura ludica latina. Sulla scorta di evidenze interne al testo, in particolare a proposito dell’identità drammatica dei suoi protagonisti e delle isotopie narrative presenti, e grazie a testimonianze esterne alla commedia, nello specifico alcune tradizioni cultuali greche e magno-greche, questa ricerca propone di intendere l’espressione basilicus iactus non come “colpo del re” bensì come “colpo (...) della regina”, con un rinvio implicito alla dea Venus e al colpo degli astragali che dalla divinità prendeva il nome.

During his celebrated 1922 debate with Bergson, Einstein famously proclaimed: “the time of the philosopher does not exist, there remains only a psychological time that differs from the physicist’s.” Einstein’s dictum, I maintain, has been metabolized by the natural sciences, which typically presuppose, more or less explicitly, the existence of a single, univocal, temporal substratum, ultimately determined by physics. This reductionistic assumption pervades much biological and biomedical practice. The chronological age allotted to individuals is conceived as an objective quantity, allowing (...) one to straightforwardly assign and compare the biological age of organisms. This essay argues that the standard practice of assessing the age and aging of organisms against the backdrop of a physical conception of time is problematic. This becomes especially evident in light of recent discoveries of various levels of senescence underlying the development of individual organisms—a phenomenon known as ‘age mosaicism.’ The bottom line is that the study of age and aging requires a biological conception of time, as opposed to a physical one. Einstein clearly wasn’t wrong about his operationalization of time in relativity theory. Still time may be less monolithic than he surmised. (shrink)

By the end of the 1820s, an innovative product was introduced in the northern Italian editorial market: technical and popular periodicals offering “useful knowledge” to a larger audience composed of members of the provincial middle-class, clergymen, and modestly educated craftsmen. By examining their medical content, this paper shows that popularisation did not merely entail disseminating a set of stable, unanimous, and trustworthy medical doctrines; rather, it represented a crucial step in the making of science during a period in which medical (...) theories were still various and contradictory. Moreover, it demonstrates that the environmental and preventative approach to disease, which these medical contributors often employed, did reflect recent developments in chemical or physical knowledge and responded to pedagogical and informative goals; but it mostly served to affirm the social usefulness of medicine and the legitimacy of health professionals' participation in determining how to regulate more general epidemiologic, social, and political issues.

In this paper I shall show that Kant's best anti-sceptical argument, found in the “Refutation of Idealism” — hereafter Refutation —, is not successful in debunking the sceptic. My strategy will be to argue that, although dependent upon transcendental idealism, the Refutation is inconsistent with it. In order to achieve this goal, I shall sketch, in section 1, the two main interpretations of Kant's idealism, namely, the ‘two world’ and the ‘two aspect’ theories. I shall maintain that the latter is (...) more in keeping with Kant's overall intentions in the Critique of Pure Reason. In section 2, I shall spell out the main points of the Refutation. In section 3, I shall argue that, in the context of the Refutation, the conception of the permanent as the pre-condition of any temporal sequence clashes with some of the main doctrines of transcendental idealism. Finally, in section 4, I shall follow some unsuccessful attempts to harmonise transcendental idealism with the Refutation. (shrink)

In the epistemological tradition, there are two main interpretations of the semantic relation that an empirical theory may bear to the real world. According to realism, the theory-world relationship should be conceived as truth; according to instrumentalism, instead, it should be limited to empirical adequacy. Then, depending on how empirical theories are conceived, either syntactically as a class of sentences, or semantically as a class of models, the concepts of truth and empirical adequacy assume different and specific forms. In this (...) paper, we review two main conceptions of truth (one sentence-based and one model-based) and two of empirical adequacy (one sentence-based and one model-based), we point out their respective difficulties, and we give a first formulation of a new general view of the theory-world relationship, which we call Methodological Constructive Realism (MCR). We then show how the content of MCR can be further specified and expressed in a definite and precise form. The bulk of the paper shows in detail how it is possible to accomplish this goal for the special case of deterministic dynamical phenomena and their correlated deterministic models. This special version of MCR is formulated as an axiomatic extension of set theory, whose specific axioms constitute a formal ontology that provides an adequate framework for analyzing the two semantic relations of truth and empirical correctness, as well as their connections.

In Unfit for the Future, Ingmar Persson and Julian Savulescu present a sophisticated argument in defense of the imperative of moral enhancement. They claim that without moral enhancement, the future of humanity is seriously compromised. The possibility of ultimate harm, caused by a dreadful terrorist attack or by a final unpreventable escalation of the present environmental crisis aggravated by the availability of cognitive enhancement, makes moral enhancement a top priority. It may be considered optimistic to think that our present moral (...) capabilities can be successfully improved by means of moral education, moral persuasion, and fear of punishment. So, without moral enhancement, drastic restrictions on human freedom would become the only alternative to prevent those dramatic potential outcomes. In this article, I will try to show that we still have reason to be less pessimistic and that Persson & Savulescu’s arguments are fortunately unconvincing. (shrink)

Um dos autores mais importantes do Renascimento é o italiano Marsílio Ficino. Deixando de lado os estudos filosóficos baseados em Aristóteles e Lucrécio, voltou-se com afã a Platão. Em seu Comentário ao Banquete de Platão, ele retoma o filósofo grego e, deixando-se influenciar também pela Ética aristotélica, por Cícero, Agostinho e os poetas italianos, entre outros, produz uma obra ainda capaz de despertar admiração e surpresa no leitor contemporâneo.

Two of the most well-known belief contraction operators are partial meet contractions (PMCs) and kernel contractions (KCs). In this paper we propose two new classes of contraction operators, namely the class of generalized partial meet contractions (GPMC) and the class of generalized kernel contractions (GKC), which strictly contain the classes of PMCs and of KCs, respectively. We identify some extra conditions that can be added to the definitions of GPMCs and of GKCs, which give rise to some interesting subclasses of (...) those classes of functions, namely the classes of extensional and of uniform GPMCs/GKCs. In the context of contractions on belief sets the classes of partial meet contractions, uniform GPMCs and extensional GPMCs are all identical. Nevertheless, when considered as operations on belief bases, the class of uniform GPMCs coincides with the class of partial meet contractions, but the extensional GPMCs constitute a new kind of belief base contraction functions whose characterizing postulate of irrelevance of syntax is extensionality—the same postulate of irrelevance of syntax which occurs in the classical axiomatic characterization of partial meet contractions for belief sets—rather than the postulate of uniformity—which is the irrelevance of syntax postulate used in the axiomatic characterization for partial meet contractions on belief bases. Analogous results are obtained regarding the classes of extensional and of uniform GKCs. We present the interrelations in the sense of inclusion among all the new classes of operators presented in this paper and several well known classes of PMCs and of KCs. (shrink)

Al hilo de la idea apuntada por el último Foucault de una historia de la verdad,se tratará de rastrear y analizar en el pensamiento del francés el carácter decisivo que tiene el momento platónico en relación con dicha historia. Así, se habrá de mostrar cómo la genealogía del sujeto moderno de verdad ha de remontarse hasta Platón para encontrar allí ciertos elementos decisivos para la compresión de nuestra historia, en la que ciertas relaciones entre el poder, la verdad y el (...) sujeto han venido a resultar determinantes, dando lugar al doble juego de objetivación y subjetivación –de dominación y libertad– que caracteriza nuestro mundo.Following on the concept of “a history of the truth” by de late Foucault, we will look into the Frenchman´s mind and attempt to pursue and analyse the sigificance of the platonic movement in relation to such history. This way, it will be necessary to show how the genealogy of the modernsubject of the truth has to return back to Plato to find there certain decisive elements for the comprehension of our history, in which certain relationships amongst the “power, the truth, and the subject matter have shown themselves as determinants agents, givind room to a double game of the objectivity and subjectitivity, of domination and freedom that marks our World.

Business Ethics: A European Review, EarlyView.

Physical inactivity and coronavirus disease 2019 signify two pandemics with negative physical, mental, and economic consequences. Younger and older people have not reached the recommended physical activity level for years. Societal restrictions due to COVID-19 additionally reduce opportunities for physical activity, and they increase social isolation. Here, we outline how playing exergames with others at home could foster physical and mental health and promote communication and discussions on exergaming. Accordingly, we highlight the educational and social benefits of exergaming at home (...) and delineate the concept of Educational and Social Exergaming. We outline specific benefits and pitfalls of exergaming regarding its physical and nonphysical effects, including educational values of discussing exergaming experiences and related topics. Moreover, we discuss the relevance of practical guidelines for educational and social exergaming at home as well as prospects for future research. Overall, educational and social exergaming could alleviate several detrimental effects of both pandemics on the health and well-being of people of all ages. (shrink)

A standard approach to examining Deleuze's concept of difference in Difference and Repetition is to follow his critique of representation through an overturning of Platonism, which Deleuze finds to be the definitive task of philosophy after Nietzsche. While engaging this largely critical project, however, there is a tendency to overlook the dimensions of Platonism that Deleuze rehabilitates in a differential and immanent register. This paper aims to recover the essential dimensions of Platonism at the very heart of Deleuze's philosophy of (...) difference. This recovery is accomplished by distinguishing Nietzsche's overturning of Platonism through his evaluation of the reactive politics of the Idea from Deleuze's own reversal of Platonism through his evaluation of the active politics of simulacra.

Questo saggio si concentra sul tema dell’ordine dell’anima ( _ ordo animae _ ) nell’etica di Alberto Magno (1200 ca.-1280). Ispirandosi a varie _ sententiae _ bibliche e integrandole con la fondamentale idea dell’ _ Etica Nicomachea _ di Aristotele per cui il fine della filosofia morale è diventare buoni ( _ ut boni fiamus _ ), Alberto concepisce l’etica non come mero “discorso filosofico”, per prendere a prestito un’etichetta da Pierre Hadot, ma come un’attività la cui preoccupazione primaria è (...) l’ordinamento – e la trasformazione e liberazione che ne seguono – di sé. Il fatto che Alberto sviluppi tale riflessione sia nei suoi commenti filosofici che in quelli biblici, affidandosi in entrambi i casi sia a fonti aristoteliche che scritturiste, testimonia poi che la sua filosofia e la sua esegesi biblica, solitamente ritratte come radicalmente separate, sono, in realtà, profondamente connesse. _ This essay focuses on the theme of the order of the soul ( _ ordo animae _ ) in the ethics of Albert the Great (1200 ca.-1280). Drawing on several biblical _ sententiae _ and integrating them with the fundamental idea of Aristotle’s _ Nicomachean Ethics _ that the end of moral philosophy is to become good ( _ ut boni fiamus _ ), Albert conceives of ethics not as a mere “philosophical discourse”, to borrow a label from Pierre Hadot, but as an activity whose primary concern is the ordering – and the consequent transformation and liberation – of the self. The fact that Albert develops such a reflection in both his philosophical and biblical commentaries, relying in either case on both Aristotelian and scriptural sources, testifies then that his philosophy and biblical exegesis, which are usually portrayed as radically separate, are, in fact, deeply connected. _.

Shamans, healers, and doctors have always known that patients may improve even if no real therapy is administered. In the Charmides, Plato noted that to soothe a headache, one needed "a kind of leaf, which required to be accompanied by a charm, and if a person would repeat the charm at the same time he used the cure, he would be made whole; but that without the charm would be of no avail". Similarly, more than two millennia later, Thomas Jefferson (...) observed, "One of the most successful physicians I have even known has assured me that he used more bread pills, drops of colored water, and powder of hickory ashes, than of all other medication put together"; Jefferson famously labeled this...
