Più studiosi hanno ritenuto che Il principe sia un’opera priva di unità composta da più tronconi redatti in momenti diversi. Altri a tutt’oggi sostengono che il suo significato resta segreto, sfuggente ed enigmatico. Questo commento al testo di Machiavelli mostra invece come Il principe sia animato da una logica che dà vita a un discorso coerente e lo compone in unità. Ne svela altresì il segreto mostrando che quel discorso approda a delineare un nuovo tipo umano non identificabile con alcuna (...) figura definita, tantomeno, come comunemente inteso, con quella di Cesare Borgia. Infine, questo commento mostra che Machiavelli subordina la realizzazione di tale tipo a un rinnovamento del modo di pensare degli esseri umani fondato sulla distinzione tra “vedere” e “sentire”, la quale allude a una teoria della conoscenza discosta dal razionalismo, dall’empirismo e dal visionarismo. Rinnovamento che costituisce la condizione di una politica volta al fine, oggi più che mai attuale, di scongiurare la scomparsa del mondo umano. (shrink)

Galvani's discovery provoked an animated debate that lasted for about a decade. So far, historians have studied only the controversy between Volta and Galvani. I show that a more extensive examination of the response to Galvani's treatise reveals a number of important issues that were characteristic of the contemporary physics and physiology but have not much attracted the attention of historians. In particular, the analysis shows the need to reappraise Galvani's role in establishing animal electricity.

Seeking a historical-philosophical approach to science teaching, narrative texts have been used as pedagogical tools to improve the learning experience of students. A review of the literature of different types of narrative texts and their different rates of effectiveness in science education is presented. This study was developed using the so-called Historical Narrative as a tool to introduce science content from a historical-philosophical approach, aiming to discuss science as a human construction. This project was carried out in a 9th grade (...) Physics class in K-12 school, in Rio de Janeiro, Brazil. The steps involved in constructing a Historical Narrative based on the controversy over animal electrical fluid between Luigi Galvani and Alessandro Volta is reported herein. Finally, qualitative research results of the activities inspired by this Historical Narrative are presented with the purpose of answering the research question: to what extent do Historical Narratives support and enhance discussions about the Nature of Science, through teaching the scientific content in a historical-philosophical approach with 9th grade students? The results indicate that Historical Narrative, based on historical episodes, is a good “door opener” to teach scientific content in a historical-philosophical approach, introducing discussions about the Nature of Science without neglecting the scientific content or simplifying the discussions about the NOS.

In lieu of an abstract, here is a brief excerpt of the content:Matter and Spirit in the Age of Animal MagnetismEric G. WilsonDuring the Romantic period, writers on both sides of the Atlantic explored the sleepwalker as a merger of holiness and horror. Emerging when scientific thinkers for the first time were connecting spirit to electricity and magnetism, the somnambulist became to certain Romantics a disclosure of the difficulty of harmonizing unseen and seen, agency and necessity. This problem prominently arose (...) in Anton Mesmer's late eighteenth-century experiments in animal magnetism, in which the sleepwalker proved a paradox: an opaque revelation of transparent currents and an unconscious vehicle of sophisticated thought. Romantics such as Coleridge embraced the somnambulist as an embodiment of these troubles involved in relating motion and meaning. Coleridge and those who responded to him saw in the hypnotized human this sobering possibility: the invisible requires the visible to make itself manifest while the visible needs the invisible to become significant. 1 This is sublime and sinister: to elevate a material form to spiritual power is transcendence; to sink the boundless into a body is grotesque.Here I explore the philosophical implications of animal magnetism, the place of the sleepwalker in the history of ideas, and the role of the hypnotized human in Romantic writers, especially Coleridge. I also meditate on relationships between matter and spirit, machine and human, word and thing. Along the way, I place the history of ideas and the works of Romantic writers in mutually illuminating dialogues. The literary texts shed fresh light on philosophical problems while the ideas reveal hidden literary elements.The somnambulistic trance had been around long before Mesmer's magnetic sleeps. For centuries, shamans had used auto-hypnosis to sound [End Page 329] their souls and other-hypnosis to cure their tribe-members' ailments. However, somnambulism could not become a scientific phenomenon until Europeans in laboratories began to study electricity and magnetism. In the early modern period, Paracelsus argued that a vital fluid courses through the cosmos. The human being draws this flow like a magnet attracts force. When the body pulls to itself evil effluvia, it falls ill. To return patients to health, Paracelsus placed magnets on painful areas. He hoped to extract the unwanted current and return it to the cosmic swirl. 2 In "magnetizing" spirit, Paracelsus opened a door for empirical inquiry into the invisible world. In 1600, William Gilbert claimed that magnets correspond to the earth: both are animated by universal attraction and repulsion. 3 By the end of the seventeenth-century, Newton proposed that things are impelled by a force that draws and repels. Newton's theory of gravity inspired natural philosophers of the next centuries to search for a principle of which the magnet and the spark are manifestations. 4During the second half of the eighteenth century and the early part of the nineteenth, natural philosophers explored electricity and magnetism with unprecedented precision. In 1752, Benjamin Franklin revealed the mystery of lightning and perhaps the spark of life. 5 Inspired by Franklin, F. C. Oetinger, J. L. Fricker, and Prokop Divisch developed a theology of electricity, based on the belief that God is the electrical current. 6 Later in the century, Luigi Galvani and Alessandro Volta debated over whether the galvanic flow might be the origin and principle of life itself. 7 A few years before Franklin harvested lightning, John Michell argued that the magnetic force is not constrained to lodestones but is possibly pervasive. Some years later, Franz Aepinus suggested that magnetism and electricity manifest a deep energy. Soon after, C. A. de Coulomb discovered the mathematical law by which electrical and magnetic forces operate (Whittaker, pp. 50–59).These findings led to the breakthroughs of the nineteenth century. 8 In 1807, Humphry Davy hypothesized that chemical elements interact through electromagnetic affinity or repulsion. 9 In 1820, H. C. Oersted demonstrated the correspondence between electricity and magnetism. The same year, A. M. Ampere formulated the laws by which electrical and magnetic currents interact (Whittaker, pp. 81–86). Michael Faraday in 1831 revealed electromagnetic induction and thus inaugurated a second Copernican revolution: he showed that matter is not solid and discrete but a field of electromagnetic energy. 10 The dreams of [End...

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.

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)

Research has shown a direct relationship between infertility-related stress and anxiety in infertile patients. The present study goes into this relationship in depth, testing the moderating role of coping strategies in the associations between specific infertility-related stress dimensions and State-Anxiety among male and female partners of infertile couples. Gender differences were also explored. Both members of 254 infertile couples completed a questionnaire consisting of Socio-demographics, Fertility Problem Inventory–Short Form, Coping Orientation to Problem Experienced–New Italian Version, and State-Trait Anxiety Inventory-Y. The (...) results revealed that Social Concern and Couple’s Relationship Concern, in both partners, and Need for Parenthood, in female partners, had positive correlations with State-Anxiety. Seeking Social Support and Avoidant coping were related to increasing levels of State-Anxiety in both partners, whereas Positive Attitude coping strategies were related to lower levels of State-Anxiety in female partners. Problem-Solving and Avoidant coping played moderating roles between specific infertility-related stress dimensions and State-Anxiety in unexpected directions. Problem-Solving exacerbated the negative effects of Social Concern, whereas Avoidant coping buffered the negative effects of several infertility-related stress dimensions in both partners. Interventions to improve stress management and psychological health in infertile couples should consider that the adequacy of coping strategies is inherently situation specific. It therefore follows that patient-centered clinical interventions should consider the potential inadequacy of promoting Problem-Solving strategies, and that even Avoidance can be an efficient strategy for dealing with specific infertility-related stress dimensions.

The main aim of the paper is to reinforce the notion that emergence is a basic characteristic of the molecular sciences in general and chemistry in particular. Although this point is well accepted, even in the primary reference on emergence, the keyword emergence is rarely utilized by chemists and molecular biologists and chemistry textbooks for undergraduates. The possible reasons for this situation are discussed. The paper first re-introduces the concept of emergence based on very simple geometrical forms; and considers some (...) simple chemical examples among low and high molecular weight compounds. On the basis of these chemical examples, a few interesting philosophical issues inherent to the field of emergence are discussed – again making the point that such examples, given their clarity and simplicity, permit one to better understand the complex philosophical issues. Thus, the question of predictability is discussed, namely whether and to what extent can emergent properties be predicted on the basis of the component’s properties; or the question of the explicability (a top down process). The relation between reductionism and emergentism is also discussed as well as the notion of downward causality and double causality (macrodeterminism); namely the question whether and to what extent the emergent properties of the higher hierarchic level affect the properties of the lower level components. Finally, the question is analyzed, whether life can be considered as an emergent property. More generally, the final point is made, that the re-introduction of the notion of emergence in chemistry, and in particular in the teaching, may bring about a deeper understanding of the meaning of chemical complexity and may bring chemistry closer to the humanistic areas of philosophy and epistemology.

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)

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)

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)

This article discusses the logic of the Epimenides Paradox using a graphical representation of the logical operators involved. The graphical representation of the Logical Operators is the one used in digital electronics. This method of investigation is very effective in revealing the hidden error in the reasoning that leads to the contradiction. The article explains the vicious circle that the mind goes through when trying to analyze the Paradox. Finally, the article proposes a solution of the Paradox with final conclusions (...) that are not paradoxical but simply counterintuitive. The endless deduction is generated by subsequent evaluations that take place on different levels. In its evaluation the Mind alternates a level of logical evaluation with a level of semantic evaluation. (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 the Dialectic of the first Critique, Kant claims that a highest being is the transcendental ideal of speculative reason. However, the Canon of the Doctrine of Method presents the highest good as an ideal of both the speculative and the practical use of reason. In this paper, I argue (1) that the highest good is the ideal of the unity of reason – unlike the ideal in the Dialectic – insofar as (2) the highest good serves both the speculative (...) and the practical employment of reason. Accordingly, I also argue that (3) these two employments are complementary, not alternative. Kant’s argument for the ideal of the highest good in the Canon shows that the unity of reason combines the two lawful employments of reason. In order to be reason’s highest ideal, this ideal cannot just mirror the demands of speculative reason – it must also involve the other fundamental employment of reason, i. e., the practical. This highest standpoint cannot be merely speculative but must be moral as well: not just a highest ideal, but also a good (the highest good). (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.
