La venerabile metafora del buon macellaio ha resistito allo scorrere del tempo molto meglio di altre fantasiose immagini della metafisica platonica: buona parte dell’ontologia contemporanea riposa tuttora sulla distinzione tra venature dell’Essere – quei confini nello spazio, nel tempo, nei mondi che effettivamente demarcherebbero entità ontologicamente autonome – e semplici linee-guida, sovraimposte dagli esseri umani per “ritagliare” nella realtà oggetti socialmente utili o cognitivamente s...

“There’s Plenty of Room at the Bottom”, said the title of Richard Feynman’s 1959 seminal conference at the California Institute of Technology. Fifty years on, nanotechnologies have led computer scientists to pay close attention to the links between physical reality and information processing. Not all the physical requirements of optimal computation are captured by traditional models—one still largely missing is reversibility. The dynamic laws of physics are reversible at microphysical level, distinct initial states of a system leading to distinct final (...) states. On the other hand, as von Neumann already conjectured, irreversible information processing is expensive: to erase a single bit of information costs ~3 × 10−21 joules at room temperature. Information entropy is a thermodynamic cost, to be paid in non-computational energy dissipation. This paper addresses the problem drawing on Edward Fredkin’s Finite Nature hypothesis: the ultimate nature of the universe is discrete and finite, satisfying the axioms of classical, atomistic mereology. The chosen model is a cellular automaton with reversible dynamics, capable of retaining memory of the information present at the beginning of the universe. Such a CA can implement the Boolean logical operations and the other building bricks of computation: it can develop and host all-purpose computers. The model is a candidate for the realization of computational systems, capable of exploiting the resources of the physical world in an efficient way, for they can host logical circuits with negligible internal energy dissipation.

Bermúdez identifies the “Interface Problem” as the central problem in the philosophy of psychology: how commonsensical psychological explanations can be integrated with lower-level explanations? In particular, since folk psychology is meant to provide causal explanations on a par with, say, neurobiological explanations, the question of how to understand the relation between the two layers arises naturally. Donald Davidson claimed that the interface problem is actually ill-posed and put forward his version of the “Autonomy Picture”, the view known as anomalous monism. (...) This work reviews Davidson’s proposal in the light of digital universes: we model the key claims of the theory using cellular automata and show that Davidson’s original version of the Autonomy Picture is immune to two arguments against autonomy.

We address an argument by Floridi (Synthese 168(1):151–178, 2009; 2011a), to the effect that digital and analogue are not features of reality, only of modes of presentation of reality. One can therefore have an informational ontology, like Floridi’s Informational Structural Realism, without commitment to a supposedly digital or analogue world. After introducing the topic in Sect. 1, in Sect. 2 we explain what the proposition expressed by the title of our paper means. In Sect. 3, we describe Floridi’s argument. In (...) the following three sections, we raise three difficulties for it, (i) an objection from intuitions: Floridi’s view is not supported by the intuitions embedded in the scientific views he exploits (Sect. 4); (ii) an objection from mereology: the view is incompatible with the world’s having parts (Sect. 5); (iii) an objection from counting: the view entails that the question of how many things there are doesn’t make sense (Sect. 6). In Sect. 7, we outline two possible ways out for Floridi’s position. Such ways out involve tampering with the logical properties of identity, and this may be bothersome enough. Thus, Floridi’s modus ponens will be our (and most ontologists’) modus tollens. (shrink)

Cellular automata (henceforth: CA) are discrete, abstract computational systems that have proved useful both as general models of complexity and as more specific representations of non-linear dynamics in a variety of scientific fields. Firstly, CA are (typically) spatially and temporally discrete: they are composed of a finite or denumerable set of homogeneous, simple units, the atoms or cells. At each time unit, the cells instantiate one of a finite set of states. They evolve in parallel at discrete time steps, following (...) state update functions or dynamical transition rules: the update of a cell state obtains by taking into account the states of cells in its local neighborhood (there are, therefore, no actions at a distance). Secondly, CA are abstract, as they can be specified in purely mathematical terms and implemented in physical structures. Thirdly, CA are computational systems: they can compute functions and solve algorithmic problems. Despite functioning in a different way from traditional, Turing machine-like devices, CA with suitable rules can emulate a universal Turing machine, and therefore compute, given Turing's Thesis, anything computable....

The use of assistance systems aimed at reducing road fatalities is spreading, especially for car drivers, but less effort has been devoted to developing and testing similar systems for powered two-wheelers. Considering that over speeding represents one of the main causal factors in road crashes and that riders are more vulnerable than drivers, in the present study we investigated the effectiveness of an assistance system which signaled speed limit violations during a simulated moped-driving task, in optimal and poor visibility conditions. (...) Participants performed four conditions of simulated riding: one baseline condition without Feedback, one Fog condition in which visual feedback was provided so as to indicate to the participants when a speed limit was exceeded, and two post-Feedback conditions with and without Fog, respectively, in which no feedback was delivered. Results showed that participants make fewer speeding violations when the feedback is not provided, after 1 month, and regardless of the visibility condition. Finally, the feedback has been proven effective in reducing speed violations in participants with an aggressive riding style, as measured in the baseline session. (shrink)

The paper set up a small “philosophical lab” for thought experiments using Digital Universes as its main tool. Digital Universes allow us to examine how mereology affects the debate on New Realism of Ferraris and shed new light on the whole notion of Realism. The semi-formal framework provides a convenient way to model the varieties of realism that are important for the program of New Realism: we then draw the natural consequences of this approach into the ontology of our world, (...) arguing that the same considerations that apply to Digital Universe would hold for chess, institutions and social objects as well. Once a particular version of mereology is chosen, there are unavoidable consequences that the very underlying structure of social ontology. We then propose a new New Realism to tackle social objects: social objects turn out to be nothing more than mereological sums, picked up by some description. (shrink)

Online controlled experiments, also known as A/B tests, have become ubiquitous. While many practical challenges in running experiments at scale have been thoroughly discussed, the ethical dimension of A/B testing has been neglected. This article fills this gap in the literature by introducing a new, soft ethics and governance framework that explicitly recognizes how the rise of an experimentation culture in industry settings brings not only unprecedented opportunities to businesses but also significant responsibilities. More precisely, the article (a) introduces a (...) set of principles to encourage ethical and responsible experimentation to protect users, customers, and society; (b) argues that ensuring compliance with the proposed principles is a complex challenge unlikely to be addressed by resorting to a one-solution response; (c) discusses the relevance and effectiveness of several mechanisms and policies in educating, governing, and incentivizing companies conducting online controlled experiments; and (d) offers a list of prompting questions specifically designed to help and empower practitioners by stimulating specific ethical deliberations and facilitating coordination among different groups of stakeholders.

La notion de « relocation » désigne le déplacement historique du visionnage cinématographique vers des milieux et des objets nouveaux. Qu’il s’agisse de regarder une œuvre cinématographique sur une tablette dans un train ou bien d’assister à un match de foot dans la salle domestique d’un home théâtre, la dispersion de l’expérience cinématographique, en cours depuis longtemps, est significativement accélérée par les nouveaux media.

This paper will be concerned with the role acquaintance plays in contemporary theories of introspection. Traditionally, the relation of acquaintance has been conceived in analytic epistemology and philosophy of mind as being only epistemically relevant inasmuch as it causes, or enables, or justifies a peculiar kind of propositional knowledge, i.e., knowledge by acquaintance. However, in recent years a novel account of the role of acquaintance in our introspective knowledge has been offered. According to this novel constitutive approach, acquaintance is, in (...) itself, a sui generis—i.e., non-propositional—kind of knowledge. As we will suggest, a stalemate between David Chalmers’ account of direct phenomenal concepts—as a prototypical example of a causal view—and Anna Giustina’s account of primitive introspection—as a prototypical example of a constitutive view—is looming in the current controversy between the two families of theories. Towards the end of the essay, we will point to some possible ways for a constitutive theorist to break the stalemate. (shrink)

While the debate on values in science focuses on normative questions on the level of the individual (e.g. should researchers try to make their work as value free as possible?), comparatively little attention has been paid to the institutional and professional norms that researchers are expected to follow. To address this knowledge gap, we conduct a content analysis of leading national codes of conduct for research integrity of European countries, and structure our analysis around the question: do these documents allow (...) for researchers to be influenced by “non-epistemic” (moral, cultural, commercial, political, etc.) values or do they prohibit such influence in compliance with the value-free ideal (VFI) of science? Our results return a complex picture. On the one hand, codes of conduct consider many non-epistemic values to be a legitimate influence on the decision-making of researchers. On the other, most of these documents include what we call _VFI-like positions_: passages claiming that researchers should be free and independent from any external influence. This shows that while many research integrity documents do not fully endorse the VFI, they do not reject it and continue to be implicitly influenced by it. This results in internal tensions and underdetermined guidance on non-epistemic values that may limit some of the uses of research integrity codes, especially for purposes of ethical self-regulation. While codes of conduct cannot be expected to decide how researchers should act in every instance, we do suggest that they acknowledge the challenges of how to integrate non-epistemic values in research in a more explicit fashion.

La riflessione politica di Francesco di Meyronnes (m. 1328) contiene un’elaborazione personale connessa ai concetti di sottomissione (subiectio) e obbedienza (oboedientia), e si inscrive all’interno del pensiero teologico-politico del suo tempo, dove il dibattito sul potere assume forme e direzioni molto diverse. Nei suoi scritti, la concezione politica di Meyronnes è espressa attraverso analogie cosmologiche, naturalistiche e metafisiche, in cui il dato filosofico e quello religioso si riverberano all’interno di un discorso circolare che da Dio va all’uomo e dall’uomo a (...) Dio. L’interrogazione dell’uomo, rivolta al funzionamento di ciò che sta al di sopra, ricerca l’ordine migliore tra i vari tipi di potere. Tra potere spirituale e potere temporale esiste un nesso che muove il secondo termine al primo “sicut ad finem”, e grazie ad esso viene nobilitato. L’obbedienza (oboedientia) di uno all’altro, che implica sottomissione (subiectio) – pur trovando il proprio fondamento implicito nello ius naturale e nella lex divina – non avviene se non per mezzo di un atto volontario.

Institutions represent a solid basis to organize and stabilize human life in diferent social contexts. They are external events in the world, but they also have a strong anchorage in the mind and in last years many scholars tried to explore their cognitive ground. Starting from the original attempt of Douglass C. North, who at the end of his career tried to establish a program called “Cognitive Institutionalism”, we discuss the merits and the limits of this approach. First, we show (...) that his statements are cognitively onerous as they imply the notions of mental models and beliefs. Instead, we argue that shared institutions do not require such a convergence and that coordination takes place in the form of social practices and habits. Second, we clarify some aspects of North’s cognitive theory avoiding the ontological reading, i.e. explaining in what sense institutions might depend on the human mind and how people are joined into a practice made possible via institutions.

Qual è lo statuto libidico dello schermo? In che modo gli schermi coinvolgono le pulsioni dello spettatore, facendo appello alla sua percezione e ai suoi desideri? Nel suo Acinema, Lyotard risponde a tali questioni, affermando che lo schermo cinematografico articola due operazioni opposte. La prima, seguendo un modello rappresentativo, trasforma lo schermo in uno specchio ortopedico – come quello descritto da Jacques Lacan – così producendo il riconoscimento del soggetto nell’immagine proiettata sullo schermo e un conseguente piacere illusorio. La seconda, (...) seguendo invece un principio anti-rappresentativo o de-rappresentativo, impedisce alle pulsioni sparse di riunirsi nell’immagine organica di un soggetto, mostrando così lo schermo stesso, come compimento del desiderio di essere delusi. Lo schermo e lo specchio risultano dunque come opposti in questa relazione dialettica? Come tenterò di mostrare in questo articolo, attraverso la riflessione di Lacan e di Merleau-Ponty, il rapporto tra schermo e specchio può essere concepito a partire dalla figura dell’intreccio ovvero del chiasma.

Il contributo mira a presentare metodi e risultati del progetto di restauro virtuale di un settore dell’antica Porto Torres/Turris Libisonis (Terme centrali, via adiacente e botteghe prospicienti - cd. palazzo del Re Barbaro), frutto di un accordo di collaborazione tra la Direzione Regionale Musei Sardegna e l’Università degli Studi di Padova. Il metodo applicato si basa su tecnologie di fruizione in Realtà Virtuale e ha permesso il restauro virtuale, geolocalizzando il modello virtuale 3D on-site: una App comanda la visualizzazione di (...) immagini equirettangolari all’interno di visori VR, permettendo visite guidate “aumentate”. Il lavoro è partito da una raccolta bibliografica ragionata, alla quale è seguita una campagna di rilievo fotogrammetrico da drone (G. Alvito, Teravista); infine, intrecciando i dati raccolti, si è proceduto alla ricostruzione 3D virtuale degli edifici. Le evidenze strutturali oggi conservate sono state integrate nella scena 3D con puntuali confronti coevi (III sec. d.C.), virtualmente ricostruiti e ricollocati in contesti d’uso verosimili, accrescendo così l’affidabilità ricostruttiva. L’intera attività ricostruttiva è stata vincolata a un rigoroso processo di validazione scientifica basato sul metodo dell’Extended matrix e l’esito finale è ora fruibile sia mediante proiezioni tradizionali (off-site, tourismA 2020), sia mediante l’utilizzo di dispositivi mobili VR (on-site, Giornate europee del patrimonio 2020). In queste e altre occasioni si è riscontrata una eccellente risposta del pubblico, agevolato dal virtuale nella percezione e nella comprensione delle evidenze e delle volumetrie antiche. (shrink)

This essay takes into account the pedagogical reform for the poor proposed in England by Andrew Bell, Joseph Lancaster and Patrick Colquhoun between Eighteenth and Nineteenth century. Differentiating individuals and reproducing social order through the implementation of a pedagogical plan is a response both to the excessive expectations of well-being raised among the English poor by the Revolution in France, and to the uncontrolled spread of crime and undisciplined behaviours in the new manufacturing districts. This is why social reformers looked (...) at the pedagogical reform of mutual instruction as a way to build the conditions of reproduction of social differences: the plans proposed by Bell and Lancaster, based on emulation, competition and merit, are supported by Colquhoun because they offer a possible solution for the problems of crime and immoral behaviour. «The order of Merit», triggered by emulation, distinction and reward, thus become the main tool of influencing poor’s expectations so to predict and discipline their conduct as future waged workers.

La ricerca condotta tra le carte private del lessicografo piemontese Giacinto Carena, conservate all’Accademia delle Scienze di Torino, ha permesso di rintracciare una vasta quantità di materiali inediti di interesse storico-linguistico. Oltre all’epistolario (con circa 200 corrispondenti, tra cui Manzoni, che gli inviò la nota lettera Sulla lingua italiana, Cherubini, Cantù, Gherardini), sono conservati i diari di viaggio, che manifestano l’evolversi dei suoi interessi per la nomenclatura scientifica, e gli appunti preparatori al Prontuario di vocaboli che Carena darà alle stampe (...) nel 1846 e 1853 e a cui seguirà una terza parte postuma nel 1860.

Fin dalle sue origini l’alchimia ha dovuto confrontarsi con il problema dell’ordine. La sua eccentricità rispetto agli altri saperi medievali poneva questioni sulla sua collocazione e sulla natura dell’oggetto che cercava, la pietra filosofale. L’articolo presenta il tentativo fatto dal medico Pietro Bono da Ferrara di riordinare la materia alchemica e di incasellarla nel sistema scientifico scolastico. Nella sua opera, la _ Pretiosa Margarita Novella _, egli utilizza il sillogismo per ordinare la trattazione dell’alchimia, la _ subalternatio _ per definirla (...) come una tra le scienze naturali e collocarla all’interno del sistema dei saperi e il concetto di _ forma specifica _ per descrivere la pietra filosofale e inserirla nel processo di generazione dei metalli. In questo modo Bono concepisce l’alchimia come una scienza che risponde a due ordini, quello naturale di generazione dei metalli, nel quale opera, e quello divino, al quale deve fare appello per trovare la pietra, che sono complementari tra loro, poiché hanno la loro origine in Dio. _ Since its origins, alchemy has had to deal with the problem of order. His eccentricity compared to other medieval knowledge posed questions about his collocation and the nature of the object he was looking for, the philosopher’s stone. This article presents the attempt, made by the doctor Pietro Bono da Ferrara, to embed alchemy in the school scientific system. In his work, the Pretiosa Margarita Novella, he uses syllogism to order the treatment of alchemy, the subalternatio to place it within the system of sciences and the concept of forma specifica to describe the philosopher’s stone and insert it in metals’ generation process. In this way, Bono conceives alchemy as a science referring to two orders, the natural one of metal generation, in which it operates, and the divine one, to which he must appeal to find the philosopher’s stone, which are complementary to each other since they both have their origin in God. _.

The paper proposes a novel longitudinal approach to the study of the rhetorical effects of media by combining Audience Research (e.g. Schrøder et al., 2003), Social Semiotics (e.g. Kress and van Leeuwen, 1996, 2001; van Leeuwen, 1999; Machin and Mayr, 2012) and Relevance Theory (Sperber and Wilson, 1995). After introducing a more nuanced model of RT’s contextual effect, the paper reports an empirical case study to explicate the methodological approach. Evidence is provided that a specific text can have a long-lasting (...) effect on an audience: a hierarchy of effects and the cognitive circumstances under which this may happen are discussed.

_Riassunto_: Il dibattito contemporaneo sull’impatto causale degli stati mentali e delle decisioni consce sui fenomeni naturali e sociali fa largo uso di dati ricavati da test neurofisiologici e comportamentali, che esplorano il ruolo di processi cognitivi inconsci e interpretazioni post-hoc caratterizzate da intenzionalità dichiarativa. I dati neuroscientifici sono spesso utilizzati per sostenere una prospettiva fisicalista che privilegia il determinismo neurocognitivo rispetto alle discussioni sul libero arbitrio. Tuttavia, questa impostazione tende a ignorare, almeno parzialmente, il dibattito sui limiti epistemologici e tecnici (...) nella generazione dei dati e i pregiudizi filosofici insiti nelle interpretazioni. Questo lavoro evidenzia tali limiti, proponendo un’analisi filosofica della relazione complessa tra razionalità, esercizio del libero arbitrio e costruzione dell’identità personale. Distinguendo il concetto di scelta autentica da quello di impulso o spinta ad agire, si sostiene una concezione enattiva e fenomenologica dell’azione umana libera, offrendo così un’interpretazione del libero arbitrio che respinge l’eliminativismo come inadeguato. Rifiutando un dualismo semplicistico, il libero arbitrio viene definito come la capacità di una soggettività incarnata, situata ed enattiva di interagire con un ambiente naturale e sociale attraverso compiti che implicano processi stratificati di valutazione e decisione. In conclusione, si argomenta che, sebbene le scienze fisiche e psicologiche possano indagare le basi dell’esecuzione dell’azione, non sono in grado di risolvere né di spiegare l’aspetto più complesso del processo decisionale stratificato ed esteso. Questo riguarda la relazione intenzionale tra la persona, considerata nella sua interezza, e un mondo ricco di valori, che conferisce senso e orientamento alle scelte individuali. Parole chiave: Libertà; Persona; Cervello; Inconscio; Determinismo/Eliminativismo; Thomas Fuchs _Embodied freedom. The role of person in decision-making_ _Abstract_: The contemporary debate on the causal impact of mental states and conscious decisions on natural and social phenomena extensively relies on data derived from neurophysiological and behavioral tests. These tests investigate the role of unconscious cognitive processes and post-hoc interpretations characterized by declarative intentionality. Neuroscientific data are often employed to support a physicalist perspective that prioritizes neurocognitive determinism over discussions of free will. However, this approach tends to partially overlook the epistemological and technical limitations inherent in data generation and the philosophical biases embedded in interpretations. This paper highlights these limitations by proposing a philosophical analysis of the complex relationship between rationality, the exercise of free will, and the construction of personal identity. By distinguishing the concept of genuine choice from that of impulse or urge to act, it advocates for an enactive and phenomenological conception of human free action, offering an interpretation of free will that rejects eliminativism as inadequate. Rejecting a simplistic dualism, free will is defined as the capacity of an embodied, situated, and enactive subjectivity to engage with a natural and social environment through tasks involving layered processes of evaluation and decision-making. In conclusion, it is argued that while physical and psychological sciences may explore the foundations of action execution, they cannot resolve nor explain the more complex aspect of the stratified and extended decision-making process. This aspect concerns the intentional relationship between the person, considered as a whole, and a world rich in values, which gives meaning and direction to individual choices. _Keywords_: Freedom; Person; Brain; Unconscious; Determinism/Eliminativism; Thomas Fuchs.
