Climate change is an existential risk reinforced by ordinary actions in afuent societies—often silently present in comfortable and enjoyable habits. This silence is sometimes broken, presenting itself as a nagging reminder of how our habits fuel a catastrophe. As a case in point, global warming has created a state of urgency among wine makers in Spain, as the alcohol level has risen to a point where it jeopardises wine quality and thereby Spanish viticulture. Eforts are currently being made to solve (...) this problem technologically by developing (non-GMO) strains of yeast that produce less alcohol. If successful, this could help save Spanish viticulture. This kind of technological solution is routinely criticised for ofering simplistic “techno-fx” solutions to solve complex societal problems. However, it is not clear what features are criticised by the notion of techno-fx and hence how to avoid this criticism. In our interpretation, the techno-fx notion is not exclusively used as a dismissive term. The notion points to a general virtue of engineering: to create technological solutions that work silently in the background. This asset of technological solutions might sometimes be problematic and sometimes not. Hence, it needs to be analysed case-by-case by paying attention to the moral relevance of the hidden implications of the technology and of the unrefective actions and habits that they facilitate. Such moral analysis will in turn inform strategies for foregrounding this technology to counteract silencing. We discuss what this means in the case of modifying yeast as a viticultural climate resilience strategy. (shrink)

The Holy Scriptures can be considered a specific kind of normative texts, whose use to assess practical moral cases requires interpretation. In the field of ethics, this interpretative problem results in the necessity of bridging the gap between the normative source – moral precepts – and the specific cases. In the history of the Church, this problem was the core of the so-called casuistry, namely the decision-making practice consisting in applying the Commandments and other principles of the Holy Scriptures to (...) specific cases or moral problems. By taking into account the sin of lying, this paper argues that casuistic texts reveal an extremely sophisticated interpretative method, grounded on “pragmatic” contextual and communicative considerations and argumentative structures that resemble the ones used in legal interpretation. These works show how the underspecified biblical text expressing an abstract norm was enriched pragmatically by completing it and modulating its meaning so that it could be used to draw a conclusion in a specific context on a specific case. The mutual interdependence between biblical interpretation, pragmatics, and argumentation sheds light on a much broader phenomenon, namely the pragmatic nature of argumentation. (shrink)

We introduce a sequent calculus B for a new logic, named basic logic. The aim of basic logic is to find a structure in the space of logics. Classical, intuitionistic, quantum and non-modal linear logics, are all obtained as extensions in a uniform way and in a single framework. We isolate three properties, which characterize B positively: reflection, symmetry and visibility. A logical constant obeys to the principle of reflection if it is characterized semantically by an equation binding it with (...) a metalinguistic link between assertions, and if its syntactic inference rules are obtained by solving that equation. All connectives of basic logic satisfy reflection. To the control of weakening and contraction of linear logic, basic logic adds a strict control of contexts, by requiring that all active formulae in all rules are isolated, that is visible. From visibility, cut-elimination follows. The full, geometric symmetry of basic logic induces known symmetries of its extensions, and adds a symmetry among them, producing the structure of a cube.

Riggs v. Palmerhas become famous since Dworkin used it to show that legal positivism is defective. The debate over the merits of Dworkin's claims is still very lively. Yet not enough attention has been paid to the fact that the content of the statute at issue inRiggswas given by thecounterfactual intentionof the legislature. According to arguments from legislative intent, a judicial decision is justified if it is based on the lawmaker's intention. But can legislative intentions be determined counterfactually? More generally, (...) what are the discursive commitments undertaken by a lawyer or a judge, in an exchange of legal reasons, when using this interpretive methodology? This paper addresses these issues considering, in particular, David Lewis's “resemblance” condition and “relevant similarity” between possible worlds in the evaluation of counterfactual statements. The analysis sheds some new light on the debate on theoretical disagreements and shows that Dworkin's conception of law as an argumentative practice is not necessarily at odds with legal positivism. It rather allows us to look at it under a better light. (shrink)

Within the technical frame supplied by the algebraic variety of diagonalizable algebras, defined by R. Magari in [2], we prove the following: Let T be any first-order theory with a predicate Pr satisfying the canonical derivability conditions, including Löb's property. Then any formula in T built up from the propositional variables $q,p_{1},...,p_{n}$ , using logical connectives and the predicate Pr, has the same "fixed-points" relative to q (that is, formulas $\psi (p_{1},...,p_{n})$ for which for all $p_{1},...,p_{n}\vdash _{T}\phi (\psi (p_{1},...,p_{n}),p_{1},...,p_{n})\leftrightarrow \psi (...) (p_{1},...,p_{n})$ ) of a formula $\phi ^{\ast}$ of the same kind, obtained from φ in an effective way. Moreover, such $\phi ^{\ast}$ is provably equivalent to the formula obtained from φ substituting with $\phi ^{\ast}$ itself all the occurrences of q which are under Pr. In the particular case where q is always under Pr in φ, $\phi ^{\ast}$ is the unique (up to provable equivalence) "fixed-point" of φ. Since this result is proved only assuming Pr to be canonical, it can be deduced that Löb's property is, in a sense, equivalent to Gödel's diagonalization lemma. All the results are proved more generally in the intuitionistic case. (shrink)

Der vorliegende Band befasst sich zentral mit dem Problem der Anwendung der Transzendentalphilosophie auf die praktische Philosophie. Zu Ehren von Marco Ivaldo haben sich einige der führenden Fichte-Interpreten zusammengetan, um das Thema diachronisch zu behandeln. Angefangen bei Kant bis hin zur zeitgenössischen Philosophie werden einige der philosophischen Hauptpositionen (Kant, Fichte, Hegel, Husserl, Deleuze und viele weitere) auf ihre Verträglichkeit mit dem transzendentalphilosophischen Ansatz in praktischer Hinsicht geprüft. ********************** The present volume deals with the problem of the application of transcendental philosophy (...) to practical philosophy. In honour of Marco Ivaldo, some of the leading experts on Fichte have teamed up to treat the subject diachronically. From Kant to contemporary philosophy, some of the main philosophical positions (Kant, Fichte, Hegel, Husserl, Deleuze, and many others) are examined in view of their compatibility with the transcendental-philosophical approach in a practical way.

Research in the field of management has increasingly focused on strategies and tools related to corporate sustainability. Of the tools examined, codes of ethics have been found to play a primary role. Many studies have investigated the content of such codes, as well as their capacity to condition the behaviour of people within organizations. However, few studies have considered the intrinsic quality of codes of ethics. This study aims to investigate the impact that specific factors—firm size, degree of internationalization and (...) industry effect—can have on the quality of codes of ethics. Based on a sample of 248 listed Italian companies, the results of the empirical analysis show that the quality standard is particularly high in larger companies and in those firms operating in industries in which relationships established with critical stakeholders—and disclosure to those stakeholders—play a crucial role. These results have interesting implications for both researchers and practitioners. (shrink)

Pretopologies were introduced in [S], and there shown to give a complete semantics for a propositional sequent calculus BL, here called basic linear logic, as well as for its extensions by structural rules,ex falso quodlibetor double negation. Immediately after Logic Colloquium '88, a conversation with Per Martin-Löf helped me to see how the pretopology semantics should be extended to predicate logic; the result now is a simple and fully constructive completeness proof for first order BL and virtually all its extensions, (...) including the usual, or structured, intuitionistic and classical logic. Such a proof clearly illustrates the fact that stronger set-theoretic principles and classical metalogic are necessary only when completeness is sought with respect to a special class of models, such as the usual two-valued models.To make the paper self-contained, I briefly review in §1 the definition of pretopologies; §2 deals with syntax and §3 with semantics. The completeness proof in §4, though similar in structure, is sensibly simpler than that in [S], and this is why it is given in detail. In §5 it is shown how little is needed to obtain completeness for extensions of BL in the same language. Finally, in §6 connections with proofs with respect to more traditional semantics are briefly investigated, and some open problems are put forward. (shrink)

In this paper, we consider the nature of two aspects of human emotional experience—moods and affects—in their relation to the concept of the person. We argue for the importance of the concept of the person in an approach to human emotional experience. This paper differentiates between the concepts of minimal self, extended self, and person. Furthermore, it offers a phenomenological proposal to understand the feeling dimension of moods and affects as critical for the differentiation of human emotional experience, and hence (...) an understanding of that experience. By way of conclusion, we opt for a narrative approach to the question of the normative dimension of emotional experience to clarify the intricate relationship between mood and personhood. (shrink)

The investigation of concept of “true” and “false” has long privileged in contemporary philosophy apophantic truth, that is, the truth of dicta (sentences or propositions). To which entities, though, beyond dicta, the predicate ‘true’ pertains? This paper sheds a light on the less frequently investigated cases where we speak of a truth of things, or res. We say, for instance, that a 17 euros banknote is not a true banknote, or that a true soldier ought to be brave. The paper, (...) thus, distinguishes, beside the concept of de dicto (apophantic) truth, the concept of de re truth and two of its subspecies: eidological truth and idiological truth. (shrink)

Starting from the formal expressions of the hydrodynamical (or “local”) quantities employed in the applications of Clifford algebras to quantum mechanics, we introduce—in terms of the ordinary tensorial language—a new definition for the field of a generic quantity. By translating from Clifford into tensor algebra, we also propose a new (nonrelativistic) velocity operator for a spin- ${\frac{1}{2}}$ particle. This operator appears as the sum of the ordinary part p/m describing the mean motion (the motion of the center-of-mass), and of a (...) second part associated with the so-called Zitterbewegung, which is the spin “internal” motion observed in the center-of-mass frame (CMF). This spin component of the velocity operator is nonzero not only in the Pauli theoretical framework, i.e., in the presence of external electromagnetic fields with a nonconstant spin function, but also in the Schrödinger case, when the wavefunction is a spin eigenstate. Thus, one gets even in the latter case a decomposition of the velocity field for the Madelung fluid into two distinct parts, which constitutes the nonrelativistic analogue of the Gordon decomposition for the Dirac current. Explicit calculations are presented for the velocity field in the particular cases of the hydrogen atom, of a spherical well potential, and of an electron in a uniform magnetic field. We find, furthermore, that the Zitterbewegung motion involves a velocity field which is solenoidal, and that the local angular velocity is parallel to the spin vector. In the presence of a nonuniform spin vector (Pauli case) we have, besides the component of the local velocity normal to the spin (present even in the Schrödinger theory), also a component which is parallel to the curl of the spin vector.

BackgroundIn Italy, the COVID-19 pandemic has caused a collective trauma. Post-traumatic growth has been defined as the subjective experience of positive psychological changes as a result of a traumatic event. PTG can involve changes in five psychological main dimensions: relating to others, new possibilities, personal strength, spiritual change, and appreciation of life. In the context of national emergencies, those PTG dimensions encompassing changes at the social level can play a role in coping strategies that involve a renewed sense of self (...) and one’s social identities, including national identities, and in turn, foster a stronger sense of trust and connection to others.AimTo investigate how each of the five PTG dimensions mediates the association between the salience of national identity and interpersonal trust in a sample of Italian young adults. Trust in national and European institutions were expected to positively predict the strength of the Italian national identity which in turn was expected to be positively associated with interpersonal trust, and the PTG relating to others dimension to mediate this association.MethodThis study involves the secondary analysis of data from a representative sample of 2,000 Italian young adults. Participants completed a web survey during the peak of the COVID-19 crisis in Italy with measures of trust in EU and national institutions, national identity, interpersonal trust, and the PTG Inventory. Structural equation modeling procedures were employed for key hypotheses tests.ResultsTrust in national institutions positively predicted national identity, which in turn was positively associated with interpersonal trust. Evidence of a full mediation effect of the PTG relating to others dimension on the association between national identity and interpersonal trust was found.DiscussionFindings contribute to clarify the psychological responses to collective traumas. In the context of Italy’s COVID-19 crisis, trust in national institutions reinforced Italian national identity, which was in turn associated with greater interpersonal trust, but only when psychological responses to the trauma involved changes in how individuals perceived and related to others, and not merely a focus on the self. Theoretical and practical implications are discussed. (shrink)

Beginning with the origins of Western philosophy, the profound creation of the Hellenic genius, Reale presents an appreciation of the Naturalists, the Sophists, Socrates, and the Minor Socratics.

This volume draws together contributions from researchers whose work builds on the theory developed by Martin-Lof over the last twenty-five years.

This work considers the novelty of Neoplatonism against platonic philosophy, characterising the former by three principie points: the monopolaristic conception, the One which is productive (a self difftisive One-Good) remaining as indefinable or ineffable and its consequences and implications. Plotino's metaphysics, therefore, finds itself before a new problem, not put by Plato: to give reason of the One, and with this, of the production of the many from the One, and in its resolution he introduces an irreductable novelty into not (...) only the platonic categories, but also into Greek thought (as the idea of positive infinitude).
