The Excellency of a Free State by Marchamont Nedham was remarkably successful in revolutionary Europe. The French edition produced in Paris in 1790 by Theophile Mandar was later used for an Italian translation, published in early 1798 in Milan, at the time of the Cisalpine Republic, by Pietro Custodi. The biographies of the two translators – both engaged in the radical politics of their time – suggest some considerations on how first one and then the other thought they could make (...) use of Needham’s text. Mandar translated Nedham to suggest the fragility of English political culture in the face of the long road travelled instead by French political philosophy. Custodi’s translation was the opposite of Mandar’s, as it showed instead all the uncertainties that in Milan could lead to the loss of liberty. In both cases, in one translation as in the other, very little remained of Nedham, because his words were used to develop a different discourse, where the translations in another language – and in a quite different context – played the role of an instrument to validate theses constructed elsewhere and established in another political framework.

Pulmonary rehabilitation has demonstrated patients’ physiological and psychosocial improvements, symptoms reduction and health-economic benefits whilst enhances the ability of the whole family to adjust to illness. However, PR remains highly inaccessible due to lack of awareness of its benefits, poor referral and availability mostly in hospitals. Novel models of PR delivery are needed to enhance its implementation while maintaining cost-efficiency. We aim to implement an innovative community-based PR programme and assess its cost-benefit. A 12-week community-based PR will be implemented in (...) primary healthcare centres where programmes are not available. Healthcare professionals will be trained. 73 patients with CRD and their caregivers will compose the experimental group. The control group will include dyads age- and disease-matched willing to collaborate in data collection but not in PR. Patients/family-centred outcomes will be dyspnoea, fatigue, cough and sputum, impact of the disease, emotional state, number of exacerbations, healthcare utilisation, health-related quality of life and family adaptability/cohesion. Other clinical outcomes will be peripheral and respiratory muscle strength, muscle thickness and cross sectional area, exercise capacity, balance and physical activity. Data will be collected at baseline, at 12 weeks, at 3- and 6-months post-PR. Changes in the outcome measures will be compared between groups, after multivariate adjustment for possible confounders, and effect sizes will be calculated. A cost-benefit analysis will be conducted. This study will enhance patients access to PR, by training healthcare professionals in the local primary healthcare centres to conduct such programmes and actively involving caregivers. The cost-benefit analysis of this intervention will provide an evidence-based insight into the economic benefit of community-based PR in chronic respiratory diseases. The trial was registered in the ClinicalTrials. gov U.S. National Library of Medicine, on 10th January, 2019. (shrink)

Background: Evidence suggesting adverse drug reactions often emerges unsystematically and unpredictably in form of anecdotal reports, case series and survey data. Safety trials and observational studies also provide crucial information regarding the (un-)safety of drugs. Hence, integrating multiple types of pharmacovigilance evidence is key to minimising the risks of harm. Methods: In previous work, we began the development of a Bayesian framework for aggregating multiple types of evidence to assess the probability of a putative causal link between drugs and side (...) effects. This framework arose out of a philosophical analysis of the Bradford Hill Guidelines. In this article, we expand the Bayesian framework and add “evidential modulators,” which bear on the assessment of the reliability of incoming study results. The overall framework for evidence synthesis, “E-Synthesis”, is then applied to a case study. Results: Theoretically and computationally, E-Synthesis exploits coherence of partly or fully independent evidence converging towards the hypothesis of interest (or of conflicting evidence with respect to it), in order to update its posterior probability. With respect to other frameworks for evidence synthesis, our Bayesian model has the unique feature of grounding its inferential machinery on a consolidated theory of hypothesis confirmation (Bayesian epistemology), and in allowing any data from heterogeneous sources (cell-data, clinical trials, epidemiological studies), and methods (e.g., frequentist hypothesis testing, Bayesian adaptive trials, etc.) to be quantitatively integrated into the same inferential framework. Conclusions: E-Synthesis is highly flexible concerning the allowed input, while at the same time relying on a consistent computational system, that is philosophically and statistically grounded. Furthermore, by introducing evidential modulators, and thereby breaking up the different dimensions of evidence (strength, relevance, reliability), E-Synthesis allows them to be explicitly tracked in updating causal hypotheses.

For a better understanding of Julián Marías’ Metaphysic Antropology, it is recommendable going back to the Ortega’s mereology, epistemology and metaphysic, especially in order to clarify the meaning of “structure”, “system”, “organ” and “function”. The vital reason is personal project as the systematic openness to its circumstance, whose unitary, empirical and structural structure is “man”.

A pesar de los matices y variaciones de significado, el concepto husserliano de intencionalidad no deja de estar al servicio de la idea clásica de la verdad como adaequatio, finalmente adaptada al orden monádico de la conciencia trascendental. Veremos, sin embargo, que en los análisis de Husserl sobre la conciencia interna del tiempo se manifiesta toda la dificultad para interpretar intencionalmente la esfera pasiva de la conciencia, peligrando la peculiar vocación a la verdad de la misma intencionalidad. Intentaremos, mediante las (...) últimas ideas husserlianas sobre la constitución eidética, encontrar una génesis pasiva del sentido ideal intencional sin perder su referencia egológica. Abstract: Despite the nuances and differences of meaning, the husserlian’s concept of intentionality supplies coherently that of classic true as adaequatio, even if adapted to the monadic order of transcendental conscience. We will show how Husserl’s analysis of inner time consciousness shows all the difficulties for an intentional interpretation of the passive sphere of consciousness, altering the peculiar vocation of intentionality to truth. Through the latest husserlian ideas on constitution, we will try to find a passive genesis to the ideal meaning of intentionality without losing its egologic reference. -/- . (shrink)

Personalized medicine relies on two points: 1) causal knowledge about the possible effects of X in a given statistical population; 2) assignment of the given individual to a suitable reference class. Regarding point 1, standard approaches to causal inference are generally considered to be characterized by a trade-off between how confidently one can establish causality in any given study (internal validity) and extrapolating such knowledge to specific target groups (external validity). Regarding point 2, it is uncertain which reference class leads (...) to the most reliable inferences. -/- Instead, pharmacovigilance focuses on both elements of the individual prediction at the same time, that is, the establishment of the possible causal link between a given drug and an observed adverse event, and the identification of possible subgroups, where such links may arise. We develop an epistemic framework that exploits the joint contribution of different dimensions of evidence and allows one to deal with the reference class problem not only by relying on statistical data about covariances, but also by drawing on causal knowledge. That is, the probability that a given individual will face a given side effect, will probabilistically depend on his characteristics and the plausible causal models in which such features become relevant. The evaluation of the causal models is grounded on the available evidence and theory. (shrink)

«Hermeneutic» means interpretation, that is, looking from a point of view. In this study we try to interpret from the vital reason, the method of Ortega y Gasset, his and his disciple Julián Marías, the Aristotelian concept of «substance». If life is the radical reality, as Ortega stresses, and the person its programmatic realization, in Marías’ opinion, a vital reason of the concept of οὐσία, means to discover its capacity to understand human life. We will find, as a matter of (...) fact, that there are four limits, essentially, that distance the philosopher from that comprehension. By them, we will find the core of the greatest contradictions of the Aristotelian thought, that has been subject to intense critics throughout its history. We will concern, especially, on the function of language in the Greek conception of reason, on the interpretations that brought to «being» and «entity» as Aristotle’s thought starting point «Hermenéutica» significa interpretar, mirar desde un punto de vista. En este estudio buscamos interpretar desde la «razón vital», el método de Ortega y Gasset y su discípulo Julián Marías, el concepto aristotélico de «sustancia». Si la vida es la realidad radical, como afirma Ortega, y la persona es su realización programática, según entiende Marías, una razón vital de la οὐσία significa descubrir su capacidad de comprensión para con la vida humana. Encontraremos, entonces, que hay esencialmente cuatro límites que desvían de esa comprensión; mediante ellos, habremos encontrado el núcleo de importantes contradicciones del pensamiento aristotélico que han sido objeto de encendidos debates a lo largo de la historia. Nos centraremos, sobre todo, en la función del lenguaje en la concepción de la razón griega, en los supuestos interpretativos del «ser» y del «ente» como puntos de partida del pensamiento de Aristóteles .

Né vers 1600 en Italie, l'opéra encourait les foudres de Marcello dès 1720. L'ouverture des salles au public, les nécessités commerciales et le vedettariat l'avaient éloigné des idéaux qui présidèrent à sa naissance. L'opuscule de Benedetto Marcello aborde, sur le ton de la dérision et de la satire, tous les aspects de l'opéra, du livret à la musique, en passant par les chanteurs, les compositeurs, les directeurs de théâtre, la mise en scène, etc. Le texte méritait une nouvelle traduction française (...) (la dernière datait de la fin du dix-neuvième siècle), plus précise et plus complète, car le savant compositeur de l'Estro poetico-armonico y déploie une verve irrésistible, proche de celle dont se servira Carlo Goldoni dans l'imprésario de Smyrne. Cette satire représente l'étincelle qui allait embraser le flambeau de la réforme par le biais du comte Francesco Algarotti (1712-1764) poète et écrivain. Son Essai sur l'Opéra en musique contient en effet tous les points importants sur lesquels Calzabigi et Gluck allaient asseoir leur reconstruction : choix du livret, rôle de la poésie et de la musique, rôle des chanteurs, du compositeur, moyens et contrôle artistiques des productions. La traduction française qu'un fit Chastellux en 1773, nonobstant sa finesse et son élégance, fait pourtant figure de " belle infidèle ". Force nous était donc d'élaborer là encore une nouvelle traduction de ce texte fondateur. A côté de ces deux grands titres, nous avons réuni un dossier important d'écrits émanant des acteurs de la réforme : Métastase, Angiolini, Calzabigi, Gluck et Du Roullet. (shrink)

En los reproches que José Ortega y Gasset le hace a Martin Heidegger sobre el problema del ser, al afirmar que este no puede ser un ciego punto de partida, una creencia, se evidencia la distancia entre dos perspectivas unidas por el horizonte real que pretenden explorar: la vida humana. Sin embargo,..

La filosofía de Brentano, más conocida por introducir el antiguo concepto de intencionalidad para distinguir los fenómenos psíquicos de los físicos, acaba siendo una peculiar metafísica en que el objeto es función de la actividad autoperceptiva del sujeto. Los conceptos de juicio como reconocimiento y de conciencia secundaria como percepción interna tienen un papel fundamental en este proceso, porque establecen, desde el comienzo de su doctrina, un ámbito de realidad indudable en que se cumple el concepto clásico de verdad como (...) adaequatio rei et intellectus; si bien con un sentido esencialmente original porque el perceptor resulta ser, a la vez, el percibido. Finalmente, pasando por una comparación con la fenomenología, podremos comprender que esta nueva relación que introduce Brentano entre sujeto y objeto se acerca a las concepciones pragmatistas, anticipando, en su sentido más profundo, importantes cambios filosóficos del existencialismo del siglo XX y de la razón vital.

The debates between Bayesian, frequentist, and other methodologies of statistics have tended to focus on conceptual justifications, sociological arguments, or mathematical proofs of their long run properties. Both Bayesian statistics and frequentist (“classical”) statistics have strong cases on these grounds. In this article, we instead approach the debates in the “Statistics Wars” from a largely unexplored angle: simulations of different methodologies’ performance in the short to medium run. We conducted a large number of simulations using a straightforward decision problem based (...) around tossing a coin with unknown bias and then placing bets. In this simulation, we programmed four players, inspired by Bayesian statistics, frequentist statistics, Jon Williamson’s version of Objective Bayesianism, and a player who simply extrapolates from observed frequencies to general frequencies. The last player functions as a benchmark: a statistical methodology should at least outperform a crude form of induction. We focused on the performance of these methodologies in guiding the players towards good decisions. Unlike an earlier simulation study of this type, we found no systematic difference in performance between the Bayesian and frequentist players, provided the Bayesian used a flat prior and the frequentist used a low confidence level. Unlike that study, we were able to use Big Data methods to mitigate problems of random error in the simulation results. The Williamsonian player, who is a novel element of our study, also had no systematic differences in their performance, provided that they use a low confidence level. These players performed similarly even in the very short run, when players were making different decisions. Our study indicates that all three methodologies should be taken seriously by philosophers and practitioners of statistics. However, the frequentist and Williamsonian performed poorly when their confidence levels were high, and the Bayesian was surprisingly harmed by biased priors, providing some unexpected lessons for these methodologies when facing this type of decision problem.

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.

La experiencia de la pobreza llama a la economía a humanizarse y a la filosofía a pensar etimológicamente desde las “normas de la casa”.

La fundamental idea orteguiana de que «mi vida» es «razón», difiere radicalmente de la concepción fenomenológica de la razón que alumbra Husserl en Ideen, esencialmente fundada en el ser. La razón vital es teoría del hombre, que es su proyecto circunstancial; su estímulo argumental procede de una reflexión estética sobre todo orientada a la comprensión del realismo y del idealismo artísticos, y cuyas consecuencias filosóficas serán decisivas.

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)

Multidimensional theories of well-being are locked into a debate about value judgment. They seek to settle which dimensions should matter for measurement and policy, and, more importantly, on what grounds to decide what should matter. Moreover, there is a gulf between theory and practice, given that measurement and policy are rarely rooted in a coherent ethical framework. Our paper engages in the debate concerning the legitimate grounds for selecting dimensions. Combining Amartya Sen's capability approach and John Rawls’ method of political (...) constructivism, we explore whether the constitution and its public culture can be used as an ethically sound informational base for selecting dimensions, and if so, why. We apply this ‘constitutional approach’ to the Italian case with the aim of deriving a set of publicly justifiable dimensions of well-being. It is a long-standing Constitution with broad public consultation at its base, which still enjoys a wide consensus. We seek to show why there is a need for more ethically sound methodological approaches to measuring well-being, pointing out the advantages of the constitutional approach, and how it may enrich the work of practitioners engaged in the policies of well-being.

Le problème du temps chez Michel Henry n’a pas encore fait l’objet d’une étude séparée. Le rejet abrupt de cette question chez l’auteur n’a certainement pas favorisé l’intérêt des critiques pour ce sujet. Dans un premier temps, en 1963 dans L’Essence de la manifestation , Michel Henry considère le problème du temps (à travers le filtre du Kantbuch de Heidegger) comme étant le « même » que celui de la récepti­vité, soit en le renvoyant à l’auto-affection. Celle-ci étant comprise comme (...) opposée ou, mieux encore, comme « étrangère » au kantisme, en tant qu’elle est affection pathétique de soi à soi. Puis, en 2000, dans Incarnation , Michel Henry conteste au « flux temporel » des Leçons pour une conscience intime du temps de Husserl la volonté néantisante du moment présent, tout en l’utilisant subrepticement dans des moments clés de son argumentation ; il lui oppose le sens de l’ « apparaître » s’auto-fondant. Enfin, nous proposons de reprendre les concepts henryens d’ « effort » et de « pouvoir-toucher », présents dans la deuxième partie d’ Incarnation , pour penser une « origine de l’espacement » préalable à la pensée de la tempora­lité ek-statique comme à celle de l’espace.

The meaning of justice can be defined according to a juridical, human, theological, ethical, biomedical, or social perspective. It should guarantee the protection of life and health, personal, civil, political, economic, and religious rights, as well as non-discrimination, inclusion, protection, and access to care. In this review, we deal with three theoretical concepts that define justice in all its aspects. (1) The utilitarian theory, which justifies moral statements on the basis of the evaluation of the consequences that an action produces, (...) elaborating a pragmatic model of medical science. (2) The libertarian theory, which considers freedom as the highest political aim, thus absolutizing the rights of the individual; here, the principle of self-determination, with respect to which the principle of permission/consent is the fundamental presupposition, plays a central role in the definition of the person. (3) The iusnaturalist theory, in which man’s moral freedom is identified with the ability to act by choosing what the intellect indicates to him as good; the natural moral law that drives every conscience to do good is therefore realized in respect for the person in the fullness of his rights. In conclusion, different forms and conceptions of justice correspond to different organizations of society and different ways of addressing ethical issues in the biomedical domain. (shrink)

This contribution addresses some bioethical and medico-legal issues of the opinion formulated by the Italian National Bioethics Committee (CNB) in response to the dilemma between the State’s duty to protect the life and health of the prisoner entrusted to its care and the prisoner’s right to exercise his freedom of expression. The prisoner hunger strike is a form of protest frequently encountered in prison and it is a form of communication but also a language used by the prisoner in order (...) to provoke changes in the prison condition. There are no rules in the prison regulations, nor in the laws governing the legal status of prisoners, that allow the conscious will of the capable and informed subject to be opposed and forced nutrition to be carried out. However, this can in no manner make therapeutic abandonment legitimate: the medical doctor should promote every action to support the patient. In the recent opinion formulated by the CNB it was remarked how self-determination is a central concept in human rights and refers to an individual’s ability to make autonomous and free decisions about his or her life and body.

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.

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...

This paper deals with the dialectic “nature/culture” in the thought of José Ortega y Gasset and related to the ideas of salvation and tragedy. Justify the elaboration of his article in the fact that this topic has not been studied in-depth through the complete works of the philosopher of the vital reason. The results/conclusions are the following ones: In a first period, it stands out the primate of culture in Ortega´s thought, who considers the last one as saviour and also (...) as something antagonistic in relation to the more instinctive and irrational nature of the individual human being as a member of humanity. We can say that submission to natural inclinations, that symbolize our barbarous, irrational and savage side, appears in Ortega’s early writings as a form of tragedy or “radical evil” ; on the other hand, in his latter thought those ones will be interpreted by Ortega not in negative terms, but as something in continuity with culture, which can became a form of tragedy.

Do imprecise beliefs lead to worse decisions under uncertainty? This BJPS Short Reads article provides an informal introduction to our use of agent-based modelling to investigate this question. We explain the strengths of imprecise probabilities for modelling evidential states. We explain how we used an agent-based model to investigate the relative performance of Imprecise Bayesian reasoners against a standard Bayesian who has precise credences. We found that the very features of Imprecise Bayesianism which give it representational strengths also cause relative (...) underperformance in this decision problem. We explain the practical relevance of this research to applications of Bayesian reasoning in areas like artificial intelligence. (shrink)

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.

This study represents an empirical, comprehensive investigation of two different inter-organisational collaborative approaches, offering a novel perspective on collaborative circular business models in the modern economy. In this vein, we explore how open innovation strategies foster the implementation of circular economy practices within a circular supply chain and a circular ecosystem. In addition, we identify and characterise stakeholders' roles in facilitating the translation of circular principles into a viable business. An inductive theorising approach was employed, leveraging an explorative multiple case (...) study methodology. Data were collected from 13 organisations involved in two collaborative networks, designed to establish upcycling practices to recover waste from the food and beverage industry. A critical realist philosophical positioning underpinned researchers' data collection and analysis. As a result, we outline the nature of two different collaborative approaches to pursue a regenerative production system through open innovation strategies: a circular supply chain and a circular ecosystem architecture. The characterisation of the coordinator and orchestrator of collaborative circular business models is also highlighted in our findings. In sum, this study contributes to the literature on circular economy by unveiling the role of open innovation in fostering circular business development. From a practical standpoint, it offers insights for managers of sustainability-oriented companies willing to implement upcycling practices. (shrink)

Can artificial agents act? Conceptual constellation for a de-humanised theory of action This paper embarks on an exploration of the concept of agency, traditionally ascribed to humans, in the context of artificial intelligence (AI). In the first two sections, it challenges the conventional dichotomy of human agency and non- human instrumentality, arguing that advancements in technology have blurred these boundaries. In the third section, the paper introduces the reader to the philosophical perspective of new materialism, which assigns causal power to (...) matter itself. This perspective suggests that agency is an emergent property of material configurations, prompting a re-evaluation of nonhuman agency. The fourth and fifth section revisit the legacy of cybernetics to understand systemic properties and feedback mechanisms, while re-admitting in the discourse also linear conditioning (discarded by new materialism) and assigning it a role in system dynamics. In the sixth section, in the light of the conceptual background examined so far, the paper proposes a revision of determinism (again partly in opposition to the new materialism and its indeterministic view) that can include both linear conditioning and circular interactions. The seventh section is devoted to propose a novel theory of action that includes AI systems – and artificial entities in general – as agents that can impact their environment and human systems. The exploration concludes with a discussion on the implications of this perspective for our understanding of action and responsibility in the age of AI. (shrink)

This paper discusses the issue of overriding the right of individual consent to participation in cluster randomised trials (CRTs). We focus on CRTs testing the efficacy of non-pharmaceutical interventions. As an example, we consider school closures during the COVID-19 pandemic. In Norway, a CRT was promoted as necessary for providing the best evidence to inform pandemic management policy. However, the proposal was rejected by the Norwegian Research Ethics Committee since it would violate the requirement for individual informed consent. This sparked (...) debate about whether ethics stand in the way of evidence-based health policy, since the Norwegian Research Ethics law’s strict requirements for individual consent make it practically impossible to carry out CRTs of public health interventions. We argue that, in the case of the school closure trial, the suggested CRT would not have eliminated an epistemic gap and thus would not have justified the violation of consent rights. First, we focus on the methodological challenges to estimating quantifiable effects of school closures in the specific case of an airborne infectious disease. Second, in line with Evidential Pluralism, we highlight the value of alternative lines of evidence for informing school closure policy in a pandemic. In general, we propose that a trial requiring the waiver of participants’ consent rights must be highly likely to eliminate an epistemic gap. We elaborate on the practical aspects of this criterion and discuss the potential advantages of adding it to the Ottawa Statement on the Ethical Design and Conduct of Cluster Randomized Trials.

The Covid-19 pandemic has been analysed and discussed from many disciplinary perspectives. An aspect that still needs critical exploration is the role—that is, the modes and forms—of regulatory interventions during the pan- demic. It is interesting to note in this regard that, in many studies, regulatory measures are labelled “non-pharma- ceutical interventions”, as if they do not have any specificity on their own and only represent a theoretically residual category. The main aim of this article is instead to focus on (...) the distinctive features of normative measures as such. As regards the article’s focus, it centres on the normative interventions in the first period of the pandemic—that is, 2020—with particular reference to Italy. We have chosen to focus on this period because the most extensive and severe restrictions introduced to combat Covid-19 were established at that time. And we have chosen to con- sider Italy because it was the first country, after China, to be hard hit by the virus and to react in a draconian manner. As regards the methodology, the article is based, in general and primarily, on an extensive interdisciplinary literature review. With reference to the Italian case, the study is additionally based on: first-hand data collection and analysis (especially concerning Italian normative measures mainly issued at the national level: their type, frequency, target, hierarchical relationships); second-hand data and analysis (for instance as regards the effectiveness of Italy’s and other countries’ regulatory measures). In discussing the Italian response to the Covid-19 pandemic, certain weaknesses have been identified; and possible lessons have been highlighted, in terms of both “planning” (i.e. the necessity to better pre-define concrete and circumscribed sets of actions) and of “meta-planning” (i.e. the necessity of better planning the way in which public authorities could and should plan and act). Although this article is mainly based on the Italian situation, what we can learn from this case is largely generalizable. (shrink)

How should we make decisions when we do not know the relevant physical probabilities? In these ambiguous situations, we cannot use our knowledge to determine expected utilities or payoffs. The traditional Bayesian answer is that we should create a probability distribution using some mix of subjective intuition and objective constraints. Imprecise Bayesians argue that this approach is inadequate for modelling ambiguity. Instead, they represent doxastic states using credal sets. Generally, insofar as we are more uncertain about the physical probability of (...) an event, there is more divergence in the credal set. Hence, their approach can represent these ambiguities via the extent of the divergence. Imprecise Bayesianism has mostly been advocated for its epistemological features. In this article, we examine its properties for decision-making. We develop a model for comparing standard and Imprecise Bayesianism by testing their performances in a classic decision problem. We find that the representational tools of Imprecise Bayesianism also cause it to underperform in our tests. This issue has been overlooked, because previous research on Imprecise Bayesianism has not utilised agent-based modelling to provide information about its performance in the short-run. Overall, we reveal the Ambiguity Dilemma for Imprecise Bayesianism: To what extent should one value representational power or decision-making performance? (shrink)
