Dal novembre 2016 al luglio 2017 Perniola ripensa alla sua vita scrivendo gli 86 capitoli che compongono questo volume, il tutto in uno stile ibrido tra il diaristico, il saggistico, l’autobiografico e il filosofico. Ognuno dei capitoli modella figure, contesti geografici, amicizie, avventure erotiche e aneddoti – che Perniola presenta come realmente accaduti – fornendo al lettore la Wunderkammer di una vita.

This paper explores the concept of "inorganic sexuality" in the work of Italian writer and philosopher Mario Perniola. The main objective is to develop the controversial and original aspects of Perniola's thought within his aesthetic theory of feeling. Perniola elaborates the so-called "thing that feels", namely a feeling in which the neutral and impersonal dimensions of the things flow into organic life and vice versa. This perspective, as will be clarified, by dissolving the vitalist and spiritualist (...) drives of the subject, enlarges the horizon of aesthetic feeling by welcoming what is commonly left outside of it: the inorganic and material world, in its surprising aspects, but also in its uncanny and disturbing ones. Therefore, the main goal of this paper is to show the significance and the value of neutral sexuality, which opens up a space of experiences beyond the traditional metaphysical oppositions such as masculine/feminine, organic/inorganic, alive/dead, real/virtual, gender/sex.

Several scholars (Bartoloni 2019, Bukdahl 2017, Vogt 2019) focused on Mario Perniola's perspective on art, post-human sexuality and political theory. Yet little has been written on the philosophical and literary sources - specifically Stoicism, the Baroque and the Avant-Gardes - which influenced his standpoint. The objective of this paper is to develop Perniola's conception of a strategically oriented beauty, which implies a connection between the aesthetic element and the political-effectual one.

The aim of this paper is to show in what terms reality can be considered as a stratification of surfaces by developing Mario Perniola's philosophy of transit. The first part will deal with the etymology of the word transit, in order to explain its meanings and uses. As it will be clarified, the development of the notion of transit goes together with the conception of reality as deep in the sense of full, available, rich, as the realm of (...) "difference" and "enigmas". The second part will explain the particular conception of temporality implied in the transit. Together with Perniola's analysis, Nietzschean and Deleuzian reflections about "amor fati" and "eternal return" will be further explored. This concept is crucial to understand not only Perniola's overall philosophy by clarifying his position against postmodern thinkers; it also provides a theoretical framework from which the task and the challenge of the philosopher in the contemporary world emerge.

Il 2021 segna gli ottant’anni dalla nascita di Mario Perniola, uno dei massimi filosofi italiani del secondo dopoguerra. Questo volume raccoglie interventi che esplorano la sua opera mostrandone la fertilità e sottolineando al tempo stesso la prossimità delle sue idee con le principali sfide del nostro tempo. Dall’Italia al Brasile, passando per gli Stati Uniti, l’Irlanda, la Francia, il Belgio, il Messico e la Cina, gli autori si soffermano su temi che comprendono l’estetica, la politica, la teoria della (...) comunicazione, i queer studies, il pensiero rituale e religioso, la sessualità e la letteratura, restituendo la plurivocità e l’originalità di un filosofo di respiro internazionale e più che mai attuale.

Este artículo analiza la cosmovisión del narrador de La ciudad y los perros en función del efecto catártico, caracterizado por conseguir la identificación con los personajes o los escenarios representados en el texto. Para obtener esa sensibilidad anhelada en el lector, es imprescindible el conocimiento de los mecanismos que conllevan la asociación de patrones afines. Por ello, se recurrirá a conceptos de Mario Perniola, Slavoj Žižek, entre otros, para determinar el desarrollo de ese proyecto de lectura idealizada. Considerando (...) esa posibilidad, se asume que durante ese proceso está presente la asimilación y el rechazo de información; es más, se erige una actitud crítica y hasta una repulsión por actos antiéticos (la violencia). Igual ocurrirá con respecto al planteamiento de la representación de la historia en la novela como trama, debido a que el lector requiere una secuencia lógica que pueda comprender (hilvanará secuencias lógicas, a pesar de que estas se muestren técnicamente dispersas o confusas); por ese motivo, la exigencia en función de su atención y su captación será necesaria (así se podrá negar o aceptar una propuesta exhibida, cuestionarla u obviarla).

In this paper I will defend the idea of the success of post-truth as one of the main features of hypermodernity. In order to understand such a claim, I will start by defining “post-truth” and showing the key differences that separate it from simple manipulation or lies. I will explain how post-truth characterizes a whole new way of understanding the difference between truth and falsity: a new attitude of indifference to the sharp distinction that moderns and ancients had placed between (...) these two notions. I will contend that this new attitude had been announced by the work of at least three recent philosophers: Harry Frankfurt, Gianni Vattimo and Mario Perniola. They give different names to “post-truth”, though, and attribute it to different causes (from anti-intellectualism to the new media and to sheer carelessness). After that, I will explore how two key aspects of hypermodernity (according to Gilles Lipovetsky), i.e. hyperindividualism and hyperconsumption, cohere with this spread of post-truth. Finally, I will summarily refer to some political and geopolitical events that corroborate the relevance of post-truth in our hypermodern world. (shrink)

It is generally argued that if the wave-function in the de Broglie–Bohm theory is a physical field, it must be a field in configuration space. Nevertheless, it is possible to interpret the wave-function as a multi-field in three-dimensional space. This approach hasn’t received the attention yet it really deserves. The aim of this paper is threefold: first, we show that the wave-function is naturally and straightforwardly construed as a multi-field; second, we show why this interpretation is superior to other interpretations (...) discussed in the literature; third, we clarify common misconceptions.

Philosophers now seem to agree that frequentism is an untenable strategy to explain the meaning of probabilities. Nevertheless, I want to revive frequentism, and I will do so by grounding probabilities on typicality in the same way as the thermodynamic arrow of time can be grounded on typicality within statistical mechanics. This account, which I will call typicality frequentism, will evade the major criticisms raised against previous forms of frequentism. In this theory, probabilities arise within a physical theory from statistical (...) behavior of almost all initial conditions. The main advantage of typicality frequentism is that it shows which kinds of probabilities (that also have empirical relevance) can be derived from physics. Although one cannot recover all probability talk in this account, this is rather a virtue than a vice, because it shows which types of probabilities can in fact arise from physics and which types need to be explained in different ways, thereby opening the path for a pluralistic account of probabilities.

What does it take to understand a phenomenon ideally, or to the highest conceivable extent? In this paper, we answer this question by arguing for five necessary conditions for ideal understanding: (i) representational accuracy, (ii) intelligibility, (iii) truth, (iv) reasonable endorsement, and (v) fitting. Even if one disagrees that there is some form of ideal understanding, these five conditions can be regarded as sufficient conditions for a particularly deep level of understanding. We then argue that grasping, novel predictions, and transparency (...) are not reasonable conditions for ideal understanding. (shrink)

I want to combine two hitherto largely independent research projects, scientific understanding and mechanistic explanations. Understanding is not only achieved by answering why-questions, that is, by providing scientific explanations, but also by answering what-questions, that is, by providing what I call scientific descriptions. Based on this distinction, I develop three forms of understanding: understanding-what, understanding-why, and understanding-how. I argue that understanding-how is a particularly deep form of understanding, because it is based on mechanistic explanations, which answer why something happens in (...) virtue of what it is made of. I apply the three forms of understanding to two case studies: first, to the historical development of thermodynamics and, second, to the differences between the Clausius and the Boltzmann entropy in explaining thermodynamic processes.

The ontological models framework distinguishes ψ-ontic from ψ-epistemic wave- functions. It is, in general, quite straightforward to categorize the wave-function of a certain quantum theory. Nevertheless, there has been a debate about the ontological status of the wave-function in the statistical interpretation of quantum mechanics: is it ψ-epistemic and incomplete or ψ-ontic and complete? I will argue that the wave- function in this interpretation is best regarded as ψ-ontic and incomplete.

In this paper we will demonstrate that a computational system can meet the criteria for autonomy laid down by classical enactivism. The two criteria that we will focus on are operational closure and structural determinism, and we will show that both can be applied to a basic example of a physically instantiated Turing machine. We will also address the question of precariousness, and briefly suggest that a precarious Turing machine could be designed. Our aim in this paper is to challenge (...) the assumption that computational systems are necessarily heteronomous systems, to try and motivate in enactivism a more nuanced and less rigid conception of computational systems, and to demonstrate to computational theorists that they might find some interesting material within the enactivist tradition, despite its historical hostility towards computationalism.

We argue that the asymmetry between diverging and converging electromagnetic waves is just one of many asymmetries in observed phenomena that can be explained by a past hypothesis and statistical postulate (together assigning probabilities to different states of matter and field in the early universe). The arrow of electromagnetic radiation is thus absorbed into a broader account of temporal asymmetries in nature. We give an accessible introduction to the problem of explaining the arrow of radiation and compare our preferred strategy (...) for explaining the arrow to three alternatives: (i) modifying the laws of electromagnetism by adding a radiation condition requiring that electromagnetic fields always be attributable to past sources, (ii) removing electromagnetic fields and having particles interact directly with one another through retarded action-at-a-distance, (iii) adopting the Wheeler-Feynman approach and having particles interact directly through half-retarded half-advanced action-at-a-distance. In addition to the asymmetry between diverging and converging waves, we also consider the related asymmetry of radiation reaction. (shrink)

This paper investigates the historical origin and ancestors of typicality, which is now a central concept in Boltzmannian Statistical Mechanics and Bohmian Mechanics. Although Ludwig Boltzmann did not use the word typicality, its main idea, namely, that something happens almost always or is valid for almost all cases, plays a crucial role for his explanation of how thermodynamic systems approach equilibrium. At the beginning of the 20th century, the focus on almost always or almost everywhere was fruitful for developing measure (...) theory and probability theory. It was apparently Hugh Everett III who first mentioned typicality in physics in 1957 while searching for a justification of the Born rule in his interpretation of quantum mechanics. The historically closest concept before these developments is moral certainty, which was invented by the medieval French theologian Jean Gerson, and it became a standard concept at least until the Age of Enlightenment, when Jakob Bernoulli proved the Law of Large numbers.

Philosophy is sometimes perceived as an abstract and nerdy discipline dealing with problems of its own creation in an isolated chamber of the Ivory Tower. And there is some truth to this view. But philosophy can help us deal with common problems, such as the disagreements we have in our everyday lives.

In this paper we explore Ronald N. Giere’s contributions to the scientific realism debate. After outlining some of his general views on the philosophy of science, we locate his contributions within the traditional scientific realism debate. We argue that Giere’s scientific perspectivism is best seen as a form of carte blanche realism, that is: a view according to which science is a practice aiming at truth, and can warrantably claim to have attained it, to a certain degree; however, it does (...) not place our confidence invariably in some specific feature of scientific representations.

We put forth an account for when to believe causal and evidential conditionals. The basic idea is to embed a causal model in an agent’s belief state. For the evaluation of conditionals seems to be relative to beliefs about both particular facts and causal relations. Unlike other attempts using causal models, we show that ours can account rather well not only for various causal but also evidential conditionals.

I analyze the meaning of mass in Newtonian mechanics. First, I explain the notion of primitive ontology, which was originally introduced in the philosophy of quantum mechanics. Then I examine the two common interpretations of mass: mass as a measure of the quantity of matter and mass as a dynamical property. I claim that the former is ill-defined, and the latter is only plausible with respect to a metaphysical interpretation of laws of nature. I explore the following options for the (...) status of laws: Humeanism, primitivism about laws, dispositionalism, and ontic structural realism. (shrink)

This is the BJPS Short Read version of the article When Fields Are Not Degrees of Freedom. In our article, Vera Hartenstein and I show that the world of classical electromagnetism might differ radically from the one we see in physics textbooks and experience day-to-day. First, light may not exist; second, the laws of electromagnetism are either incomplete or completely different; and, third, the mathematics needed to make exact calculations with these novel laws is in early development and not part (...) of the general mathematics curriculum at colleges and universities.

Deployment Realism resists Laudan’s and Lyons’ objections to the “No Miracle Argument” by arguing that a hypothesis is most probably true when it is deployed essentially in a novel prediction. However, Lyons criticized Psillos’ criterion of essentiality, maintaining that Deployment Realism should be committed to all the actually deployed assumptions. But since many actually deployed assumptions proved false, he concludes that the No Miracle Argument and Deployment Realism fail. I reply that the essentiality condition is required by Occam’s razor. In (...) fact, there is a simpler formulation of essentiality which escapes Lyons’ criticisms and rescues the No Miracle Argument and Deployment Realism from their purported historical counterexamples: a hypothesis is essential when it has no proper parts (in Yablo’s sense) sufficient to derive the same prediction. Although essentiality so conceived cannot be detected prospectively, this is just natural, and it is not a problem but an advantage for Deployment Realism. (shrink)

In the scientific communities most criticisms are constructive, while they are destructive in the humanistic circles. Indeed, scientists circulate their drafts among colleagues and students, hoping to elicit their comments and suggestions before submitting their work to publication. In contrast, philosophers and political thinkers attack their rivals, without sparing arguments ad hominem or even insults. The reason for this difference is that scientists are after the truth, whereas most humanists fight for more or less noble causes, from swelling their own (...) curricula to joining crusades for or against rationality, realism, justice, or what have you.

El intento de estas páginas es el de seleccionar dentro de la semántica del miedo que contribuye a organizar la imagen moderna del orden político y jurídico el elemento específico del pánico, en la hipótesis de que este último constituya una diferencia que es asimismo un recurso epistémico. Dicho de un modo directo: si el miedo se presenta como una referencia constitutiva del orden, de su constitución como de su mantenimiento, el pánico parece, en cambio, cargado de un signo contrario; (...) nos habla de la disolución de un agregado dado por supuesto y es inclusivo en el perimetrar los límites y las condiciones de posibilidad. El objetivo es aquel de repasar algunos momentos de la historia del pánico buscando argumentar que el pánico es una pasión política, en el sentido de que se refiere a aquello de lo que la político está hecha, y al mismo tiempo es expresión de un límite "pasional" de la política, en tanto que define políticamente un límite interno. Respecto a tal objetivo, esta aportación no reivindica más que los caracteres de un hilvanado necesitante de un desarrollo ulterior por lo que se refiere no solo a aquello que no se incluye (y es obviamente mucho), sino también a los nudos que de forma conscientemente provisional se indican. Además, se limita a una periodizacion histórica que es de alguna manera preliminar, deteniéndose en el umbral de la fase en la cual el pánico es una palabra de un discurso disciplinar, es parte del objeto de un saber codificado (psicología, sociología, ciencia política), incluso si no desempeña necesariamente un rol apaciguador.

Against certain positivistic and neopositivistic strictures still rooted in our society, Agazzi argues that knowing the invisible is possible, not just in science, but also in metaphysics, in morals, in aesthetics, and in other areas, including, in a sense, religion. The book also examines many examples of such knowledge, surveying not only the great classics of philosophy, but various immortal masterpieces of art, music and literature. It is not just a treatise in epistemology, but a book of philosophy in the (...) most complete and traditional sense, for it discusses knowledge not only for its own sake, but also as a guide to culture, morality, happiness and to the sense of life. Thus, it also provides some important suggestions on how to face our time of crisis and an uncertain future. Despite Agazzi’s proverbial rigor and clarity, his project is so momentous and demanding that I discuss certain points which might deserve further explication and argumentation. (shrink)

A re-evaluation of the notion of vacuum in quantum electrodynamics is presented, focusing on the vacuum of the quantized electromagnetic field. In contrast to the ‘nothingness’ associated to the idea of classical vacuum, subtle aspects are found in relation to the vacuum of the quantized electromagnetic field both at theoretical and experimental levels. These are not the usually called vacuum effects. The view defended here is that the so-called vacuum effects are not due to the ground state of the quantized (...) electromagnetic field. Nevertheless it is possible to maintain an empirically demonstrable notion of vacuum state that is consistent with the interpretation of the formalism of the theory. (shrink)

This article deals with the most relevant philosophical side of Albert the Great’s analysis of alchemy, aimed at clarifying what alchemical transmutation consists in and whether this process can ultimately be accomplished by men. The Dominican master handles the problem differently in the earlier commentary on Lombardus’ Libri Sententiarum and in works like the De mineralibus, in which a more mature idea of the connection between art and nature is developed. In this respect, Albert’s interpretation intersects with Avicenna’s De congelatione, (...) a fundamental text for the Latin medieval debate on alchemy, whose reception has shaped his understanding of the alchemical art. The Dominican master gradually assumes a more lenient position towards the claims of the alchemical process of transmutation, which he explains by resorting to the similitudes between alchemy and medicine and the comparison of artificial transmutation with natural processes such as the generatio ex putrefactione and the natural formation of minerals.

There is not much of a consensus on almost anything about quantum mechanics. I take it, however, that the minimum consensus is that "although quantum mechanics is empirically successful, quantum mechanics is hard to understand." Quantum mechanics, in the way it is presented in most textbooks, does indeed not provide a clear picture of reality that would make it a theory to be understood. In her new book, "The World in the Wave Function: A Metaphysics for Quantum Physics," Alyssa Ney (...) tries to make this blurry picture of reality more precise, even if this picture will turn out to be heterodox and unfamiliar.

Traditionally, computational theory (CT) and dynamical systems theory (DST) have presented themselves as opposed and incompatible paradigms in cognitive science. There have been some efforts to reconcile these paradigms, mainly, by assimilating DST to CT at the expenses of its anti-representationalist commitments. In this paper, building on Piccinini’s mechanistic account of computation and the notion of functional closure, we explore an alternative conciliatory strategy. We try to assimilate CT to DST by dropping its representationalist commitments, and by inviting CT to (...) recognize the functionally closed nature of some computational systems. (shrink)

The aim of this paper is to analyze time-asymmetric quantum mechanics with respect to the problems of irreversibility and of time's arrow. We begin with arguing that both problems are conceptually different. Then, we show that, contrary to a common opinion, the theory's ability to describe irreversible quantum processes is not a consequence of the semigroup evolution laws expressing the non-time-reversal invariance of the theory. Finally, we argue that time-asymmetric quantum mechanics, either in Prigogine's version or in Bohm's version, does (...) not solve the problem of the arrow of time because it does not supply a substantial and theoretically founded criterion for distinguishing between the two directions of time.

When adopting a sound logical system, reasonings made within this system are correct. The situation with reasonings expressed, at least in part, with natural language is much more ambiguous. One way to be certain of the correctness of these reasonings is to provide a logical model of them. To conclude that a reasoning process is correct we need the logical model to be faithful to the reasoning. In this case, the reasoning inherits, so to speak, the correctness of the logical (...) model. There is a weak link in this procedure, which we call the faithfulness problem: how do we decide that the logical model is faithful to the reasoning that it is supposed to model? That is an issue external to logic, and we do not have rigorous formal methods to make the decision. The purpose of this paper is to expose the faithfulness problem (not to solve it). For that purpose, we will consider two examples, one from the geometrical reasoning in Euclid’s Elements and the other from a study on deductive reasoning in the psychology of reasoning. (shrink)

Chez les scientifiques, la plupart des critiques sont constructives, alors qu’elles sont destructrices chez les humanistes.

We show that in the Maxwell–Lorentz theory of classical electrodynamics most initial values for fields and particles lead to an ill-defined dynamics, as they exhibit singularities or discontinuities along light-cones. This phenomenon suggests that the Maxwell equations and the Lorentz force law ought rather to be read as a system of delay differential equations, that is, differential equations that relate a function and its derivatives at different times. This mathematical reformulation, however, leads to physical and philosophical consequences for the ontological (...) status of the electromagnetic field. In particular, fields cannot be taken as independent degrees of freedom, which suggests that one should not add them to the ontology. (shrink)

Abstract We examine the construction of electromagnetism in its current form, and in an alternative form, from a point of view that combines a minimal realism with strict rational demands. We begin by discussing the requests of reason when constructing a theory and next, we follow the historical development as presented in the record of original publications, the underlying epistemology (often explained by the authors) and the mathematical constructions. The historical construction develops along socio-political disputes (mainly, the reunification of Germany (...) and the second industrial revolution), epistemic disputes (at least two demarcations of science in conflict) and several theories of electromagnetism. Such disputes resulted in the militant adoption of the ether by some, a position that expanded in parallel with the expansion of Prussia. This way of thinking was facilitated by the earlier adoption of a standpoint that required, as a condition for understanding, the use of physical hypothesis in the form of analogies; an attitude that is antithetic to Newton's “hypotheses non fingo”. While the material ether was finally abandoned, the epistemology survived in the form of “substantialism” and a metaphysical ether: the space. The militants of the ether attributed certainties regarding the ether to Faraday and Maxwell, when they only expressed doubts and curiosity. Thus, the official story is not the real history. This was achieved by the operation of detaching Maxwell's electromagnetism from its construction and introducing a new game of formulae and interpretations. Large and important parts of Maxwell work are today not known, as for example, the rules for the transformation of the electromagnetic potentials between moving systems. When experiments showed that all the theories based in the material ether were incorrect, a new interpretation was offered: Special Relativity (SR). At the end of the transformation period a pragmatic view of science, well adapted to the industrial society, had emerged, as well as a new protagonist: the theoretical physicist. The rival theory of delayed action at distance initiated under the influence of Gauss was forgotten in the midst of the intellectual warfare. The theory is indistinguishable in formulae from Maxwell's and its earlier versions are the departing point of Maxwell for the construction of his equations. We show in a mathematical appendix that such (relational) theory can incorporate Lorentz' contributions as well as Maxwell's transformations and C. Neumann's action, without resource to the ether. Demarcation criteria was further changed at the end of the period making room for habits and intuitions. When these intuited criteria are examined by critical reason (seeking for the fundaments) they can be sharpened with the use of the Non Arbitrariness Principle, which throws light over the arbitrariness in the construction of SR. Under a fully rational view SR is not acceptable, it requires to adopt a less demanding epistemology that detaches the concept from the conception, such as Einstein's own view in this respect, inherited from Hertz. In conclusion: we have shown in this relevant exercise how the reality we accept depends on earlier, irrational, decisions that are not offered for examination but rather are inherited from the culture.

This paper explores some aspects of the scientific study of creativity by focusing on intentional attempts to create instances of linguistic humour. We argue that this sort of creativity can be accounted for within an influential cognitive approach but that said framework is not a recipe for producing novel instances of humour and may even preclude them. We start by identifying three great puzzles that arise when trying to pin down the core traits of creativity, and some of the ways (...) taken by Cognitive Studies in this quest. We then consider what we call 'creative humour', which exhibits the core features of the aforesaid creativity. We then explore how a key cognitive approach to human communication can account for creative humour. We end by drawing lessons and highlighting limitations to cognitive approaches to creativity.

In legal proceedings, a fact-finder needs to decide whether a defendant is guilty or not based on probabilistic evidence. We defend the thesis that the defendant should be found guilty just in case it is rational for the fact-finder to believe that the defendant is guilty.

Finally, we defend our account of legal proof against challenges from (...) Staffel and compare it to a recent competitor put forth by Moss. (shrink)

I confront Feyerabend's position and critical rationalism in order to have a foundation or starting point for my (historical) investigation. The main difference of his position towards falsificationism is the belief that different theories cannot be discussed rationally. Feyerabend is convinced that Galilei's observations with the telescope in the historical context of the Copernican revolution supports his criticism. In particular, he argues that the Copernican theory was supported by deficient hypotheses, and falsifications were disposed by ad hoc hypotheses and propaganda. (...) Furthermore, he claims that his philosophy of science reconstructs Galilei's defence of the Copernican theory. He introduces a central principle of his position (the principle of tenacity) in order to justify a research strategy of not eliminating falsified theories. He tries to show that the tenacious defence of a theory corresponds to Galilei's defence of the Copernican theory. Remarkably, Feyerabend's approach to explain the development of science earns an important support from his interpretation of Galilei's observations. On this basis I give a falsificationist interpretation of Galilei's observations with the telescope, and oppose this interpretation to Feyerabend's. From a falsificationist perspective, auxiliary hypotheses compete during the Copernican revolution which can (with some effort) be critically discussed. Then I analyse the historical case in order to test Feyerabend's interpretation of the Copernican revolution. Inter alias I investigate thoroughly whether Galilei, as Feyerabend claims, immunised falsifications of the Copernican theory by the introduction of ad hoc hypotheses. The investigation considers Galilei's explanation of Venus' phases, his establishment of the irradiation hypothesis, the explanation of the telescope's functionality, and the role of the reproducibility of the observations with the telescope. Finally I provide a rational reconstruction of Galilei's falsification of the Ptolemaic theory. The formalisation shows that Galilei was not a cautious critical rationalist, but a very confident scientist using the method of falsification. (shrink)

The purpose of this work is to address what notion of geometrical object and geometrical figure we have in different kinds of geometry: practical, pure, and applied. Also, we address the relation between geometrical objects and figures when this is possible, which is the case of pure and applied geometry. In practical geometry it turns out that there is no conception of geometrical object.

In Latin Europe, the controversy over spontaneous generation of perfect animals – namely those whose breeding occurs through sexual reproduction – is received in different ways, varying from positions very close to Avicenna’s, as in the case of Pietro Pomponazzi, to interpretations that rather refer to Averroes’ perspective. To this ‘Averroist front’ undoubtedly belongs the figure of Urbano da Bologna, author of the Expositio commenti Averrois in VIII libros Physicorum – a work that can be defined a supercommentary to Averroes’ (...) Physica – composed in Bologna around 1334. The present study aims to provide the complete transcription of a quaestio that is present in the work – but which was disputed according to its author also in public – as an example of the elaboration of the theme of spontaneous generation in the early 14th century. The text deals with many aspects of the problem, especially elaborating on the correspondence between each specific form and its appropriate matter, in the light of the lively debates of the time, and reveals a mature understanding of Aristotle’s natural philosophy and its Averroist interpretation.

As systems based on opaque Artificial Intelligence (AI) continue to flourish in diverse real-world applications, understanding these black box models has become paramount. In response, Explainable AI (XAI) has emerged as a field of research with practical and ethical benefits across various domains. This paper not only highlights the advancements in XAI and its application in real-world scenarios but also addresses the ongoing challenges within XAI, emphasizing the need for broader perspectives and collaborative efforts. We bring together experts from diverse (...) fields to identify open problems, striving to synchronize research agendas and accelerate XAI in practical applications. By fostering collaborative discussion and interdisciplinary cooperation, we aim to propel XAI forward, contributing to its continued success. Our goal is to put forward a comprehensive proposal for advancing XAI. To achieve this goal, we present a manifesto of 27 open problems categorized into nine categories. These challenges encapsulate the complexities and nuances of XAI and offer a road map for future research. For each problem, we provide promising research directions in the hope of harnessing the collective intelligence of interested stakeholders. (shrink)

Il problema apparentemente insolubile di una giustificazione non circolare dell’induzione diverrebbe più abbordabile se invece di chiederci solo cosa ci assicura che un fenomeno osservato si riprodurrà in modo uguale in un numero potenzialmente infinito di casi futuri, ci chiedessimo anche come si spiega che esso si sia manifestato fin qui in modo identico e senza eccezioni in un numero di casi finito ma assai alto. E’ questa l’idea della giustificazione abduttiva dell’induzione, avanzata in forme diverse da Armstrong, Foster e (...) BonJour: serie talmente regolari di fenomeni sono da un punto di vista logico talmente improbabili che se il mondo fosse puramente casuale (se cioè gli eventi si presentassero con frequenza proporzionale alla loro probabilità logica) esse non potrebbero verificarsi se non per una coincidenza miracolosa. Pertanto, tali regolarità si spiegano solo assumendo che siano prodotte da meccanismi o necessità nomiche; ma se questo è il caso, è corretto concludere che tali regolarità persisteranno anche in futuro senza eccezioni, e dunque le inferenze induttive su di esse sono giustificate. Anche Kornblith argomenta dall’effettivo successo delle inferenze induttive all’esistenza di regolarità oggettive in natura; mentre Sankey parte dall’ uniformità della natura per giustificare l’induzione. Congiungendo le due argomentazioni, dunque, si ottiene di nuovo una giustificazione dell’induzione in base all’argomento del “se non è un miracolo …”. Un ostacolo su questa via è specificare in che senso la natura sia uniforme (dato che ovviamente non lo è in ogni suo aspetto) e di quali regolarità possiamo aspettarci che persistano senza eccezione anche in futuro (dato che evidentemente non tutte lo fanno: l’acqua non bolle sempre a 100°, la pressione non è sempre funzione della temperatura, e così via). Entrano qui in gioco le conoscenze di sfondo e la ripetizione delle osservazioni in condizioni diverse, che ci mostrano quali circostanze siano rilevanti al verificarsi del fenomeno dato. In tal modo, le nostre descrizioni delle regolarità naturali convergono su descrizioni che specificano sia le condizioni individualmente necessarie e congiuntamente sufficienti, sia tutti gli argomenti delle funzioni che costituiscono tali regolarità. Ciò consente di formulare i principi di Uniformità della Natura e di Induzione in modo non generico (e dunque, a seconda della formulazione, vuoto o eccessivo), ma circostanziato: così essi asseriscono, rispettivamente, che la natura è uniforme negli aspetti evidenziati dalle descrizioni su cui convergiamo grazie alle osservazioni ripetute, e che solo queste descrizioni possono essere induttivamente generalizzate. Ciò consente anche di risolvere enigmi alla Goodman, quali: poiché le osservazioni ci hanno mostrato (solo) il verificarsi di una data regolarità fino al momento presente t, come possiamo presumere che essa si verificherà anche dopo t? La risposta è che osservazioni e conoscenza di sfondo non ci dicono che vi sia alcun limite temporale tra le condizioni necessarie della regolarità data. (shrink)
