FREGE AND ŁUKASIEWICZ ON LOGICAL VALUES Our article regards the connections between the views on semantics of Gottlob Frege and Jan Łukasiewicz. We are especially focused on the problem of logical values and their ontological interpetation. The paper is composed of three parts. In the first section we point out the general tendencies in the reception of Frege’s logical theory in the Lvov-Warsaw Philosophical School. The second section is dedicated to Frege’s semantics, especially his analysis of sense and meaning of (...) propositions. In the third section we reconstruct Łukasiewicz’s propositional semantics from the period when he was inspired by Frege’s semantics. We also critically examine the widespread opinion, according to which the ontological interpretation of logical values proposed by Łukasiewicz is entirely consistent with Frege’s concept. (shrink)

Borsboom and colleagues have recently proposed a “network theory” of psychiatric disorders that conceptualizes psychiatric disorders as relatively stable networks of causally interacting symptoms. They have also claimed that the network theory should include non-symptom variables such as environmental factors. How are environmental factors incorporated in the network theory, and what kind of explanations of psychiatric disorders can such an “extended” network theory provide? The aim of this article is to critically examine what explanatory strategies the network theory that includes (...) both symptoms and environmental factors can accommodate. We first analyze how proponents of the network theory conceptualize the relations between symptoms and between symptoms and environmental factors. Their claims suggest that the network theory could provide insight into the causal mechanisms underlying psychiatric disorders. We assess these claims in light of network analysis, Woodward’s interventionist theory, and mechanistic explanation, and show that they can only be satisfied with additional assumptions and requirements. Then, we examine their claim that network characteristics may explain the dynamics of psychiatric disorders by means of a topological explanatory strategy. We argue that the network theory could accommodate topological explanations of symptom networks, but we also point out that this poses some difficulties. Finally, we suggest that a multilayer network account of psychiatric disorders might allow for the integration of symptoms and non-symptom factors related to psychiatric disorders and could accommodate both causal/mechanistic and topological explanations.

We present a new approach to the mathematical objects of General Relativity in terms of which a generic f(R)-gravity theory gravitation is written in a first-order (à la Palatini) formalism, and introduce the concept of Dark Metric which could bypass the emergence of disturbing concepts as Dark Energy and Dark Matter. These issues are related to the fact that General Relativity could not be the definitive theory of Gravitation due to several shortcomings that come out both from theoretical and experimental (...) viewpoints. At large scales, the attempts to match it with the recent observational data lead to invoke Dark Energy and Dark Matter as the bulk components of the cosmic fluid. Since no final evidence, at fundamental level, exists for such ingredients, it could be useful to reconsider the gravitational sector in order to see if suitable extensions of General Relativity could solve the shortcomings present at infrared scales.

The balance between births and deaths in an age-structured population is strongly influenced by the spatial distribution of sub-populations. Our aim was to describe the demographic process of a fish population in an hierarchical dendritic river network, by taking into account the possible movements of individuals. We tried also to quantify the effect of river network changes (damming or channelling) on the global fish population dynamics. The Salmo trutta life pattern was taken as an example for.We proposed a model which (...) includes the demographic and the migration processes, considering migration fast compared to demography. The population was divided into three age-classes and subdivided into fifteen spatial patches, thus having 45 state variables. Both processes were described by means of constant transfer coefficients, so we were dealing with a linear system of difference equations. The discrete case of the variable aggregation method allowed the study of the system through the dominant elements of a much simpler linear system with only three global variables: the total number of individuals in each age-class.

Este artigo é um diálogo com Hegel e Gadamer, partindo da pergunta: "O que é arte?''. Hegel é um divisor de águas; pode-se dizer que a arte antes de Hegel é uma coisa e depois de Hegel outra. Com Hegel diremos que a arte "morreu" ou foi supra assumida pelo espírito absoluto; se isso não significa morte, é, pelo menos, perda de identidade - de autonomia. Com Gadamer diremos que a arte é arte, sem estar dizendo uma tautologia; pois essa (...) seria a melhor forma de dizer que arte não tem conceito e nem depende de conceito para ser arte; a arte é enquanto tal, sem pendências e sem dependências.

Psychiatric disorders present distinct clinical challenges which are partly attributable to their multifactorial aetiology and the absence of laboratory tests that can be used to confirm diagnosis or predict risk. Psychiatric disorders are highly heritable, but also polygenic, with genetic risk conferred by interactions between thousands of variants of small effect that can be summarized in a polygenic risk score. We discuss four areas in which the use of polygenic risk scores in psychiatric research and clinical contexts could have ethical (...) implications. First, there is concern that clinical use of polygenic risk scores may exacerbate existing health inequities. Second, research findings regarding polygenic risk could be misinterpreted in stigmatising or discriminatory ways. Third, there are concerns associated with testing minors as well as eugenics concerns elicited by prenatal polygenic risk testing. Fourth, potential challenges that could arise with the feedback and interpretation of high polygenic risk for a psychiatric disorder would require consideration. While there would be extensive overlap with the challenges of feeding back genetic findings in general, the potential clinical use of polygenic risk scoring warrants discussion in its own right, given the recency of this possibility. To this end, we discuss how lay interpretations of risk and genetic information could intersect. Consideration of these factors would be necessary for ensuring effective and constructive communication and interpretation of polygenic risk information which, in turn, could have implications for the uptake of any therapeutic recommendations. Recent advances in polygenic risk scoring have major implications for its clinical potential, however, care should be taken to ensure that communication of polygenic risk does not feed into problematic assumptions regarding mental disorders or support reductive interpretations.

Human flourishing is the topic of an increasing number of books and articles in educational philosophy. Flourishing should be regarded as an ideal aim of education. If this is defended, the first step should be to elucidate what is meant by flourishing, and what exactly the concept entails. Listing formal criteria can facilitate reflection on the ideal of flourishing as an aim of education. We took Aristotelian eudaimonia as a prototype to construct two criteria for the concept of human flourishing: (...) human flourishing is regarded as intrinsically worthwhile and flourishing means ‘actualisation of human potential’. The second criterion has three sub-criteria: flourishing is about a whole life, it is a ‘dynamic state’ and flourishing presupposes there being objective goods. (shrink)

In this article we defend a moral conception of cosmopolitanism and its relevance for moral education. Our moral conception of cosmopolitanism presumes that persons possess an inherent dignity in the Kantian sense and therefore they should be recognised as ends‐in‐themselves. We argue that cosmopolitan ideals can inspire moral educators to awaken and cultivate in their pupils an orientation and inclination to struggle against injustice. Moral cosmopolitanism, in other words, should more explicitly inform the work that moral educators do. Real‐world constraints (...) on moral action and the need to prioritise one’s sometimes conflicting responsibilities will often qualify cosmopolitan justice as supererogatory. This fact does not absolve persons from aspiring to see themselves as having the moral obligation to help others in need, while recognising that their factual obligations are more modest in being bound by what they are actually able to do.

In this paper we provide a defence of cosmopolitanism from a liberal perspective, examining its moral underpinnings, including moral obligations predicated on a belief in common humanity and the fundamental dignity of human people, cultural capacities that include an embrace of pluralism and a fallibilist disposition, and pragmatist resolve in finding humanitarian solutions to real problems that people face. We also scrutinise the ideal of cosmopolitanism by considering the ‘deeply religious’ as the sort of people about whom it may be (...) said that irreconcilable tensions exist between certain types of commitment and/or belonging and what the demands of cosmopolitanism involve.

In this review paper, we discuss how gravity and spin can be obtained as the realization of the local Conformal-Affine group of symmetry transformations. In particular, we show how gravitation is a gauge theory which can be obtained starting from some local invariance as the Poincaré local symmetry. We review previous results where the inhomogeneous connection coefficients, transforming under the Lorentz group, give rise to gravitational gauge potentials which can be used to define covariant derivatives accommodating minimal couplings of matter, (...) gauge fields (and then spin connections). After we show, in a self-contained approach, how the tetrads and the Lorentz group can be used to induce the spacetime metric and then the Invariance Induced Gravity can be directly obtained both in holonomic and anholonomic pictures. Besides, we show how tensor valued connection forms act as auxiliary dynamical fields associated with the dilation, special conformal and deformation (shear) degrees of freedom, inherent to the bundle manifold. As a result, this allows to determine the bundle curvature of the theory and then to construct boundary topological invariants which give rise to a prototype (source free) gravitational Lagrangian. Finally, the Bianchi identities, the covariant field equations and the gauge currents are obtained determining completely the dynamics. (shrink)
