We prove that the general scheme for physical theories that we have called semantic realism(SR) in some previous papers copes successfully with a number of EPR-like paradoxes when applied to quantum physics (QP). In particular, we consider the old arguments by Furry and Bohm- Aharonov and show that they are not valid within a SR framework. Moreover, we consider the Bell-Kochen-Specker und the Bell theorems that should prove that QP is inherently contextual and nonlocal, respectively, and show that they can (...) be invalidated in the SR approach. This removes the seeming contradiction between the basic assumptions of SR and QP, and proves that some problematic features that are usually attributed to QP, us contextuality and nonlocality, occur because of the adoption of a verificationist position, from one side, and from an insufficient adherence to the operational principles that have inspired QP itself, from the other side.

The Renaissance perspective represents the three-dimensional space onto a bi-dimensional one. This cultural construction, which unifies real and virtual, like all simulations, has some limitations – the main one is that it only works from a precise viewpoint that rules the illusion. When moving away from this position the illusion becomes imperfect. Similar to physics, where reality depends on the observer’s position, perspective depends on the viewer’s position. Since perspective has been inherited by photography, cinema, video, computer images, virtual reality, (...) 3D videogames, we live in a perspective-based culture. In perception the boundaries between opposite qualities are often blurred and even indistinguishable. A screen is generally considered as rectangular, but it can be viewed as really rectangular only from its central perpendicular axis, at the crossing of the diagonals. When moving from this position it should appear as trapezoidal, but people still say it is rectangular: because they see it as rectangular or because they know it is rectangular? This threshold between vision and knowledge is imperceptible and obscure. Something similar happens with the senses. They are considered as separate entities: touch, hear, sight, smell and taste are described as distinct ways to detect the phenomenal world. But they are intermingled; the boundaries that are supposed to separate them are apparent: they are logically separable but not separate. The sensorial system is a cohesive and interrelated continuum where the senses act in synergy with each other. Continuity and discreteness, indistinguishability and distinction, inseparability and division are qualities to individuate, describe, classify and/or communicate the phenomena. These qualities are both theoretical and technical, since they depend on the general perspective of the analysis, on the goals to pursue, on the scale at which the phenomena are observed and on the accuracy of the instruments that are used.

The concepts of molecular structure and molecular shape are ubiquitous in the chemical literature, where they are often taken as synonyms, with unavoidable drawbacks in chemistry teaching. A third concept, molecular topology, is less frequent but it is a reference term in molecular research domains such as Quantitative Structure–Activity Relationships. The present paper proposes an epistemological analysis of these three notions, aimed at clarifying the nature of their relationship, as well as the contiguities and differences between them. At first, we (...) discuss the various acceptations of the terms molecular structure and molecular shape. Then, we examine some crucial milestones in the history of these concepts and we analyse the relationship between structure, shape and topology from an epistemological viewpoint. We point out the distinguishing features of each concept and we show that their semantic openness, that may be fruitful in a specialized context, turns into a source of incoherence and inaccuracy in the teaching context, fostered by the misleading use of these terms made by textbooks. Eventually, we propose a criterion fit to discriminate between the conceptual domains of molecular shape, molecular structure and molecular topology. (shrink)

In recent years, there has been increasing interest in investigating science communication. Some studies that address this issue attempt to develop a model to determine the level of confidence that an author or a scientific community has at a given time towards a theory or a group of theories. A well-established approach suggests that, in order to determine the level of certainty authors have with regard to the statements they make, one can identify specific lexical and morphosyntactical markers which indicate (...) their epistemic attitudes. This method is considered particularly appealing because it permits the development of an algorithmic model based on the quantitative analysis of the occurrence of these markers to assess automatically and objectively the opinion of an author or the predominant opinion of a scientific community on a topic at a given time. In this contribution we show that this line of research presents many kinds of problems especially when it is applied to research articles. To this aim, we propose two main lines of reasoning. The first one relies generally on the argumentative structure of scientific articles and shows that certainty/uncertainty markers are used differently in different argument forms and that therefore their number/frequency of use does not offer reliable indications for determining whether the topic at issue is considered by the authors to be more or less factual/speculative. The second one is based on the analysis of a sample of psychiatric research articles on homosexuality written over a long time span and taken from The British Journal of Psychiatry. Since the psychiatric perspective on homosexuality changed radically during the decades in which these articles were published, they offer an inventory of various kinds of argumentative strategies directed both at defending and confuting dominant as well as marginal positions. We focus especially on uncertainty markers and show that frequently the positions stated using expressions indicating uncertainty are actually not considered as conjectural or speculative by their authors, but that the use of uncertainty markers is motivated by a number of different and often incongruent rhetorical strategies.

In questo contributo tenterò di rispondere ad una domanda fondamentale e assai complessa: la concezione di Dio come Esse Ipsum Subsistens rischia una deriva verso il monismo parmenideo? L’indagine verterà dapprima sul superamento di Aristotele della visione parmenidea e poi si concentrerà sulla metafisica dell’essere di Tommaso d’Aquino che, se correttamente intesa, non rischia affatto una deriva verso il monismo ontologico. Saranno infatti presentati alcuni passi che comprovano come il concetto centrale della concezione di Tommaso, quello di partecipazione, garantisca proprio (...) dal rischio del monismo, a patto che si intenda la presenza di Dio negli enti non in un senso quantitativo.

This article explores the early biogeographical debates that shaped the beginning of limnology, focusing on the differences of opinion concerning the origins of pelagic fauna between two pioneering scientists: Pietro Pavesi and François-Alphonse Forel. The study examines how Pavesi’s hypothesis of a marine origin for pelagic fauna contrasts with Forel’s theory of passive distribution, situating their arguments within a broader Darwinian framework. The first part of the paper provides a historical overview of Italian limnology, highlighting Pavesi’s contributions and interpreting Forel’s (...) writings to underscore the significance of discovering pelagic fauna in conceptualizing lakes as microcosms. The second part compares Pavesi’s and Forel’s hypotheses, emphasizing their impact on the scientific understanding of freshwater ecosystems. The importance of this discovery, in both historical and scientific contexts, lies in recognizing the presence of plankton in lakes as a crucial element for the mature formulation of ecological concepts, such as the ecosystem.

The standard interpretation of quantum physics (QP) and some recent generalizations of this theory rest on the adoption of a rerificationist theory of truth and meaning, while most proposals for modifying and interpreting QP in a “realistic” way attribute an ontological status to theoretical physical entities (ontological realism). Both terms of this dichotomy are criticizable, and many quantum paradoxes can be attributed to it. We discuss a new viewpoint in this paper (semantic realism, or briefly SR), which applies both to (...) classical physics (CP) and to QP. and is characterized by the attempt of giving up verificationism without adopting ontological realism. As a first step, we construct a formalized observative language L endowed with a correspondence truth theory. Then, we state a set of axioms by means of L which hold both in CP and in QP. and construct a further language Lv which can express bothtestable andtheoretical properties of a given physical system. The concepts ofmeaning andtestability do not collapse in L and Le hence we can distinguish between semantic and pragmatic compatibility of physical properties and define the concepts of testability and conjoint testability of statements of L and Le. In this context a new metatheoretical principle (MGP) is stated, which limits the validity of empirical physical laws. By applying SR (in particular. MGP) to QP, one can interpret quantum logic as a theory of testability in QP, show that QP is semantically incomplete, and invalidate the widespread claim that contextuality is unavoidable in QP. Furthermore. SR introduces some changes in the conventional interpretation of ideal measurements and Heisenberg’s uncertainty principle. (shrink)

In some sections of On Certainty, Wittgenstein uses the term “persuasion,” pitting it, on the one hand, against “giving reasons”, and comparing it, on the other, to conversion, while, finally, defining it as “giving someone one's own picture of the world.” In this essay, I analyse these sections, in an effort to fit them into the broader context of On Certainty, and to clarify the meaning and the limits of the comparison between persuasion and conversion. My aim is to show (...) that persuasion as Wittgenstein understands it here is quite similar to what we could call “re-education.”. (shrink)

The aim of this article is to show the crucial role of Blaise Pascal’s work for the development of Martin Heidegger’s early philosophical project – which lasted until the Turn [Kehre] of the 1930s. The scattered but decisive presence of quotes from the French thinker clearly shows how fundamental he was, both methodologically and content-wise, for Heidegger’s initial elaboration of the question of Being [Seinsfrage] and the Existential Analytic of Dasein [Daseinanalytik].

In both Introductions to the Critique of Judgment Kant seems to identify the a priori principle at the basis of aesthetic judgments with the principle that guides reflective judgment in its cognitive inquiry of nature, i.e. the purposiveness of nature or systematicity. For instance Kant writes.

This article aims to provide a semiotic analysis of environmental law and youth protests. More precisely, drawing on speech act theory this article regards both as types of communication and teases out the inherent voice and message, specifically with regard to the interests of future generations. The argument unfolds in three steps. First, the article looks into speaker and speech of environmental law and argues that it speaks, as legislation does, in the first-person plural voice of a ‘we’. Second, the (...) article examines a speech of Greta Thunberg through the lens of Stanley Cavell’s theory of passionate utterances. This interpretation will unlock the political stakes of Thunberg’s speech as she claims standing with those responsible for enacting environmental law. Finally, the consequences of this reading will be analysed by relating message and voice of environmental law. As youth protests question ordinary forms of political representation, new ways of safeguarding the interests of future generations are called upon. (shrink)

The first part of this paper aims to highlight the analogies between Schutz’s vision of the natural attitude and Wittgenstein’s vision of a phenomenon that concerns the same problematic field, i.e. certainty, the belief of common sense that is free of all doubt, that the world “out there” is as it appears, absolutely real. These certainties form the basis, the foundation of language games and therefore of knowledge in general and in its entirety. This foundation is unfounded and yet indispensable. (...) The second part of the paper examines an important topic analysed by Wittgenstein, related to the aforementioned problem: the language transposition of pre-predicative, pre-reflective and non-propositional certainties, the cornerstones of which are “hinge propositions”, whose hybrid nature can be identified in the shift from empirical propositions to grammatical rules.

Kant’s theory of peace has been reinterpreted under one of the most influential research programs of our times: The so-called democratic peace theory. In particular, the third ingredient of Kant’s “recipe” for peace —the cosmopolitan right to visit—has been recognized as a powerful and effective instrument to reduce militarized interstate conflicts. In the hands of political scientists, however, this ingredient has often become nothing more than a set of rules for securing and facilitating international trade and economic interdependence. This article (...) argues that this narrow reading mistakes international trade as the essence of the third definitive article. Kant sees economic interdependence as a means to realize what cosmopolitan right is truly about, that is, the affirmation of a set of rules for protecting humans qua humans, the creation of communal bonds among individuals beyond national or group loyalties, and the promotion of a global moral conscience modeled on the natural rights of man.

The discovery of incommensurability by the Pythagoreans is usually ascribed to geometric or arithmetic questions, but already Tannery stressed the hypothesis that it had a music-theoretical origin. In this paper, I try to show that such hypothesis is correct, and, in addition, I try to understand why it was almost completely ignored so far.

Only recently research in social psychology has started to systematically investigate intergroup attitudes among members of stigmatized minority groups. In particular, the study of the way people with mental health problems perceive the social groups around them is so far very scarce. In this work, we focused on people with schizophrenia, analyzing their attitudes toward another stigmatized group, namely Black individuals. In Study 1, the attitudes toward White and Black people were assessed in a sample of respondents with a diagnosis (...) of schizophrenia and in a sample of non-clinical individuals. Results showed the presence of less negative attitudes toward the minority outgroup among the clinical sample. In Study 2, we aimed at investigating what members belonging to the majority group believe about the attitudes toward Black people held by individuals with a diagnosis of schizophrenia. In general, results suggested a general awareness in lay persons that people with a diagnosis of schizophrenia, as compared to people with no history of mental disorders, hold reduced negative attitudes toward Black individuals. Overall, these results may help to enrich our knowledge about social cognition among members of stigmatized groups in general and, more specifically, among individuals with a diagnosis of schizophrenia.

We reedit in the dossier of this issue an essay of Luigi Luzzatti first came out in «Nuova Anthologia» in 1880. In it Luzzatti rereads the British constitutional history thanks to a set of biological metaphors and analogies, which are analyzed and historically framed in the introduction of Luca Ciancio. This approach of Luzzatti further enhances the reconstruction of history of Constitutions he offers analyzing the works of the greatest historians of his time.
