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 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)

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 lieu of an abstract, here is a brief excerpt of the content:Message to Buddhists for the Feast of Vesakh 2007:Christians and Buddhists: Educating Communities to Live in Harmony and PeacePaul Cardinal Poupard, President and Archbishop Pier Luigi Celata, SecretaryDear Buddhist Friends,1. On the occasion of the festival of Vesakh, I am writing to Buddhist communities in different parts of the world to convey my own good wishes, as well as those of the Pontifical Council for Interreligious Dialogue.2. We, (...) Catholics and Buddhists, enjoy a good relationship and our contacts, collaboration and implementation of diverse programmes have helped to deepen our understanding of each other. Dialogue is the sure path to fruitful interreligious relations. It deepens respect and nurtures the desire to live in harmony with others.3. The Second Vatican Council teaches that the entire human race shares a common origin and a common destiny: God, our Creator and the goal of our earthly pilgrimage. Similarly, Pope Benedict XVI, in his 2007 Message for the World Day of Peace, observed: "As one created in the image of God, each individual human being has the dignity of a person; he or she is not just something, but someone, capable of self-knowledge, self-possession, free self-giving and entering into communion with others" (n. 2).4. Building a community requires concrete gestures which reflect the respect for the dignity of others. Furthermore, as religious people, we are convinced that "there is a moral logic which is built into human life and which makes possible dialogue between individuals and peoples" (ibid, n. 3). Yet, there are people today who still need to learn about others and other people's beliefs in order to overcome prejudices and misunderstandings. This sad reality, if it is to be overcome, demands much effort [End Page 131] on the part of both civic and religious leaders. Even in places where people experience daily the ravages of war, fueled by sentiments of hatred and vengeance, trust can be restored. Together we can help to create the space and the opportunities for people to talk, listen, share regrets and offer forgiveness for each other's past mistakes.5. Education for peace is a responsibility which must be borne by all sectors of society. Of course, this starts in ordinary homes where the family, the fundamental pillar of society, strives to transmit traditional and sound values to children by a deliberate effort to inform their consciences. The younger generations deserve and indeed thrive upon value-based education which reinforces respect, acceptance, compassion and equality. It is important therefore that schools, both government and faith-based, do all possible to support parents in the delicate but satisfying task of raising children to appreciate all that is good and true.6. The media's power to shape minds, especially of the young, cannot be underestimated. While the irresponsible elements within it are increasingly being recognized for what they are, it is also the case that much good can be effected through quality productions and educational programmes. When people working within the media exercise their moral conscience, it is possible to dispel ignorance and impart knowledge, preserve social values, and portray the transcendental dimension of life which arises from the spiritual nature of all people. Religious believers serve society admirably by collaborating in such projects for the common good.7. Ultimately, the aim of true education is to bring the individual to encounter the ultimate purpose of life. This motivates the person to serve broken humanity. Together may we continue to contribute toward peace and harmony in our society and the world. We Catholics join you with our heartfelt greetings as you celebrate this feast and I wish you once again a happy Vesakh.

Nel dibattito teorico, la metafora della mappa è stata spesso usata per esplorare il ruolo della nozione di verità nel rapporto tra linguaggio, rappresentazioni, realtà. Le mappe sono sempre prospettiche, legate a interessi (cognitivi e non cognitivi) di chi le elabora; come ha osservato Michael Lynch, "il mondo non si mappa da sé". Per quanto diverse esse siano, assumiamo in genere che le pratiche descrittive possano aspirare a qualche forma di verità e corrispondere al modo in cui le cose stanno. (...) Non è facile spiegare in che cosa consista questa "corrispondenza", anche perché è controversa la possibilità di distinguere quanto, nelle rappresentazioni linguistiche, dipende dal mondo e quanto dai nostri schemi concettuali. Il ruolo del concetto di verità diventa sempre più complesso, se si prendono sul serio le differenze nei modi di accedervi e nei campi oggettivi di riferimento; ciò dà spazio ad uno spettro molto ampio di posizioni filosofiche, fra loro contrastanti, che rimescolano le carte delle tradizionali controversie tra realisti, antirealisti, relativisti. I saggi compresi in questo volume costituiscono un momento di incontro volto ad afferrare e discutere la fisionomia di queste controversie. (shrink)

Siamo ormai lontani dalla stagione in cui la forza propulsiva della “svolta linguistica” si impose come tendenza dominante nel dibattito filosofico. Da varie angolazioni si è potuto parlare negli ultimi anni di pictorial turn come antidoto all’egemonia del paradigma linguistico in filosofia. Il volume Verità, Immagine, Normatività. Truth, Image, and Normativity non si inserisce direttamente in questa nuova tendenza, ma ruota comunque intorno a questioni che derivano dal medesimo sfondo. I 24 saggi qui raccolti tengono conto dei diversi ruoli che (...) le immagini possono svolgere, a seconda che si focalizzi la loro dimensione descrittiva o normativa, e indagano alcuni aspetti del rapporto tra immagine e linguaggio. Questi problemi di filosofia dell’immagine, intesa sia come immagine cognitiva sia come immagine grafica, costituiscono il fil rouge di questo volume. Una tale riflessione sui linguaggi figurati e sulla comunicazione visiva non-linguistica costringe a riformulare in termini nuovi le grandi domande concernenti le tradizionali nozioni di verità, oggettività, normatività, consenso e persuasione.

"Depuis une quinzaine d'années, les études sur Montesquieu se sont profondément renouvelées. Le corpus lui-même, grâce aux OEuvres complètes en cours, et notamment avec la première publication intégrale du manuscrit de travail de L'Esprit des lois, offre des perspectives inédites. Mais c'est aussi l'approche même qui a changé : la diversité des questions et des thèmes que son oeuvre permet d'aborder élargit le champ de la recherche, de la philosophie morale et politique à l'histoire ou l'anthropologie, ou encore à la (...) pensée du droit et de la société. Ce volume en tire méthodiquement les conséquences. Dans la perspective de l'édition critique des OEuvres complètes de Montesquieu, c'est à une relecture non pas radicale, mais en finesse et en profondeur qu'invite ce volume, en développant le rapport entre l'homme et la société, en redessinant la relation aux grands massifs de la tradition philosophique d'une pensée dont on suit jusqu'à son terme la logique, en suggérant des relations inédites à travers des rapprochements qui s'imposent, mais n'avaient pourtant guère été faits : ce qui restait informe ou informulé s'est éclairé, ce dont on devinait l'importance s'est approfondi. Ensuite, que restera-t-il à (re)lire? L'Esprit des lois."--Page [4] de la couverture. (shrink)

Psychophysical experiments have demonstrated large and highly systematic perceptual distortions of tactile space. Such a space can be referred to our experience of the spatial organisation of objects, at representational level, through touch, in analogy with the familiar concept of visual space. We investigated the neural basis of tactile space by analysing activity patterns induced by tactile stimulation of nine points on a 3 × 3 square grid on the hand dorsum using functional magnetic resonance imaging. We used a searchlight (...) approach within pre-defined regions of interests to compute the pairwise Euclidean distances between the activity patterns elicited by tactile stimulation. Then, we used multidimensional scaling to reconstruct tactile space at the neural level and compare it with skin space at the perceptual level. Our reconstructions of the shape of skin space in contralateral primary somatosensory and motor cortices reveal that it is distorted in a way that matches the perceptual shape of skin space. This suggests that early sensorimotor areas critically contribute to the distorted internal representation of tactile space on the hand dorsum. (shrink)

Luigi Giussani, a high school religion teacher throughout the 1950s and 1960s, grounded his teachings in the vast body of experience to be found in Christianity's two-thousand-year history. He told his students, “I'm not here to make you adopt the ideas I will give you as your own, but to teach you a method for judging the things I will say.” Throughout his life, education was one of Giussani's primary intellectual interests. He believed that effective education required an adequate (...) background in the Christian tradition, presented within a lived experience that underscored the capacity of the faith to answer universal questions. What he proposed was a process that allowed one to sift through tradition, critically examining it and comparing it against the ultimate criteria for judgment: the desires of the heart. In Giussani's view, the primary concern was to “educate the human heart as God made it.” In The Risk of Education he states that fear leads students to associate this process of criticism with negativity or doubt. Yet, without an education in criticism, students cannot develop conviction. At a time when young people are abandoning the church and questioning the value of faith, Giussani's method of judging and verifying Christianity as an experience seems a necessary intervention. In The Risk of Education he argues that, ultimately, education and the Christian message reveal themselves through human freedom. (shrink)

This article analyses the use of the term “‘political oeconomy” in the Wealth of Nations, considered by many the founding text of the discipline of Political Economy. It shows that Adam Smith could not accept the use of the term “political oeconomy” that had been made by other authors to indicate the subject matter of his scientific inquiry, devoted to the nature and causes of the wealth of nations; he used the term “political oeconomy” as a synonym for economic policy, (...) especially in the fourth book of the Wealth of Nations. In order to understand this statement, it is necessary to keep in mind the methodological and epistemological perspective developed by Smith; in his view, the inquiry into the nature and causes of the wealth of nations would have to discover the almost unchangeable rules that presided over the choices of the legislators in the field of public economy and in the management of public resources. By contrast, the term “political oeconomy” was used by Smith exactly to indicate the policies really adopted in these fields, policies which frequently altered the system of natural liberty.

In this paper, I will survey the “received view” of the interpretation of relativity theory in Natorp and Cassirer. Neo-Kantian and non-neo-Kantian scholars (such as Hentschel or Ferrari) usually distinguish Natorp’s reading from Cassirer’s by virtue of “immunising” and “revising” strategies. “Immunisation” consists of a strict defence of Kantian philosophy, while “revision” pertains to the modification of Kantianism depending on relativity theory. In this respect, I will suggest some arguments that will put things in perspective. In particular, I will show (...) that Natorp’s interpretation is justified considering the state of physical research in 1910. By the same token, I will highlight where Cassirer leverages immunising strategies. However, I will demonstrate that, in contrast to Natorp, the influence of general relativity (GR) is pivotal to Cassirer and it does have an impact on his whole epistemology (and philosophy), implying a highly radical reform of pure intuition in light of general covariance. I will also add that Cassirer may have a bearing on Einstein as to the possibility of reconsidering his former censure of Kantian philosophy. (shrink)

A μ-algebra is a model of a first-order theory that is an extension of the theory of bounded lattices, that comes with pairs of terms where μx.f is axiomatized as the least prefixed point of f, whose axioms are equations or equational implications.Standard μ-algebras are complete meaning that their lattice reduct is a complete lattice. We prove that any nontrivial quasivariety of μ-algebras contains a μ-algebra that has no embedding into a complete μ-algebra.We then focus on modal μ-algebras, i.e. algebraic (...) models of the propositional modal μ-calculus. We prove that free modal μ-algebras satisfy a condition–reminiscent of Whitman’s condition for free lattices–which allows us to prove that modal operators are adjoints on free modal μ-algebras, least prefixed points of Σ1-operations satisfy the constructive relation μx.f=logical and operatorn≥0fn. These properties imply the following statement: the MacNeille–Dedekind completion of a free modal μ-algebra is a complete modal μ-algebra and moreover the canonical embedding preserves all the operations in the class image of the fixed point alternation hierarchy.
