Between the two horns of Jørgensen's dilemma, the authors opt for that according to which logic deals not only with truth and falsity but also with those concepts not possessing this semantic reference. Notwithstanding the “descriptive” prejudice, deontic logic has gained validity among modal logics. The technical foundation proposed consists in an abstract characterization of logical consequence. By identifying in the abstract notion of consequence the primitive from which to begin, it is possible to define the connectives - even those (...) of obligation - by means of the rules of introduction or elimination in a context of derivation.

At the end of the eighteenth century and beginning of the 19th, Spain and the Italian States contributed to the development of European agricultural science and the improvement of manufacturing. They collaborated with each other and reworked the most advanced models of France, Central Europe and Great Britain. Despite their somewhat less prosperous economic status, they demonstrated great originality in research and experimentation. In this process, botanical knowledge served as a starting point for a new epistemological path. Through three case (...) studies – the botanists Antonio José Cavanilles and Domenico Nocca, and the agriculturist Filippo Re – my article analyses how Spanish and Italian naturalists and learned individuals contributed to forming the concept of ‘economic botany’ through the exchange of seeds, plant specimens, books, journals, and – more in general – opinions, becoming germinal forces in a large transnational network.

This book explores the philosophical, legal, and theological roots of Western multiculturalism, that is, the encounter and coexistence of different cultures within a liberal society. Rather than concerning themselves with the particulars of cultural dialogue, the authors of this volume go deeper and question the very reality of "multiculturalism" itself. As a whole the volume devotes attention to the origins of human nature, arguing that regardless of how different another person or culture seems to be, universal human experience discloses what (...) it means to be human and to relate to others and to God. The contributors represent different cultures and faith traditions but are united in friendship and in the conviction that the Christian faith enables an authentic approach to long-standing debates on multiculturalism.

Power-law city-size distributions are a statistical regularity researched in many countries and urban systems. In this history of science treatise we reconsider Felix Auerbach’s paper published in 1913. We reviewed his analysis and found (i) that a constant absolute concentration, as introduced by him, is equivalent to a power-law distribution with exponent $$\approx 1$$ ≈ 1, (ii) that Auerbach describes this equivalence, and (iii) that Auerbach also pioneered the empirical analysis of city-size distributions across countries, regions, and time periods. We (...) further investigate his legacy as reflected in citations and find that important follow-up work, e.g. by Lotka (Elements of physical biology. Williams & Wilkins Company, Baltimore, 1925) and Zipf (Human behavior and the principle of least effort: an introduction to human ecology, Martino Publishing, Manfield Centre, CT (2012), 1949), does give proper reference to his discovery—but others do not. For example, only approximately 20% of city-related works citing Zipf (1949) also cite Auerbach (Petermanns Geogr Mitteilungen 59(74):74–76, 1913). To our best knowledge, Lotka (1925) was the first to describe the power-law rank-size rule as it is analyzed today. Saibante (Metron Rivista Internazionale di Statistica 7(2):53–99, 1928), building on Auerbach and Lotka, investigated the power-law rank-size rule across countries, regions, and time periods. Zipf’s achievement was to embed these findings in his monumental 1949 book. We suggest that the use of “Auerbach–Lotka–Zipf law” (or “ALZ-law”) is more appropriate than “Zipf’s law for cities”, which also avoids confusion with Zipf’s law for word frequency. We end the treatise with biographical notes on Auerbach. (shrink)

Philosophy & Social Criticism, Ahead of Print. The article deals with the ontological configuration and political appropriation of difference in modern, capitalist societies. Against fragmented accounts of difference, it is examined the evolution from situations of wide socio-spatial diversity to the gradual instrumentalisation and selective hierarchisation of those elements of difference that can be inserted in market-based relations, whilst the majority of differences are ignored and disregarded. The instrumentalisation of difference under capitalism – the reduction of extended socio-spatial difference to (...) the interests and priorities of the stronger segments of society who emphasise their distinctive features in the attempt to exert power and control over those considered inferior and subordinate – has more than just an impact on social or interpersonal relations but constitutes an active worldmaking force that operates, primarily, via the promotion of indifference. The analysis is informed by the Hegelian framework of consciousness and reason that is based on what the German philosopher calls the laws of experience accumulated through social interaction. Hegel’s Phenomenology of Spirit can, therefore, move social theory forward to a critical interrogation of lived and contested differences. The instrumentalised metabolism of difference, following Hegelian metaphysics, is basically the result of self-estrangement and externalisation of the self, not because of self-serving interests but exactly because of its incompleteness and the need to be actualised in the other, who is also incomplete. Likewise, all particulars are moments actualised in the universal, which is also a changeable moment of itself. Thought the negation of otherness, followed by a negation of the negation, difference can be then embraced in its entirety, as it remains a central explanatory concept for social criticism. (shrink)

The purpose of the article is to present the ideas that the Austrian physicist Ludwig Boltzmann developed on the role of classical mechanics in physics. He had elaborated them at a time when classical mechanics began to be considered as not being any more the ground for all other physical theories. Boltzmann never accepted this conclusion. He rejected it, developing at the same time some ideas on the epistemological nature of scientific theories. According to him, scientific theories are representations of (...) natural phenomena.

Analysing both mainstream and underground computer-related press sources from 1982 to 1991, a discursive core is displayed revolving around contamination and sexually transmissible diseases. The 'computer virus' metaphor, popularized in that period, came to resonate with mounting moral panic over the HIV/AIDS epidemic. These anxieties about the body are then conceptualized (and historically contextualized) along two dimensions : 1) the political proximity between HIV/AIDS activists and computer hackers during the FDA clinical trials controversy of 1987-88 ; 2) the ideological reinforcement (...) provided by academic progressive elements to these political actions.

Water values serve as an entry point into the intricacies of public policies and management approaches. Values are contingent assessments that emerge out of socio-ecological relations and reflect particular demands, legacies and opportunities. The concept of value positionality is introduced as the synthesis of multiple expressions of worthiness cherished by a social group. Positionality is a metaphor that connects the phenomenological understanding of water value with the politics of everyday life and the broader politico-institutional framework. It entails a cluster of (...) meanings expressed through territorialised interactions across time, locations and scales. Positionalities converge or depart according to value praxis, that is, the clash of competing valuation approaches seeking legitimisation. (shrink)

Emotion-processing impairment represents a risk factor for the development of somatic illness, affecting negatively both health-related quality of life and disease management in several chronic diseases. The present pilot study aims at investigating the associations between alexithymia and depression, anxiety, and HRQoL in patients with Hashimoto’s thyroiditis ; examining the association between these three psychological conditions together with HRQoL, and thyroid autoantibodies status as well as thyroid echotexture in patients with HT; and comparing the intensity of all these clinical psychological (...) features in patients with HT versus controls. Twenty-one patients with serologically or ultrasonographically verified HT and 16 controls with non-toxic goiter or postsurgical hypothyroidism were recruited for this study. Serum thyrotropin and free thyroxine, as well as thyroid autoantibodies, were assayed. Alexithymia, depression, anxiety, and HRQoL were assessed with Toronto Alexithymia Scale; Beck Depression Inventory, second edition; Hamilton Anxiety Rating Scale; and Health Survey Short-Form 36, respectively. A negative relationship between the difficulty to describe feelings and the cognitive component of depression was found. Besides, patients with seronegative HT had lower somatic anxiety than patients with HT who tested positive. Besides, no statistically significant difference was found between patients with HT and controls with regard to somatic anxiety. The present study suggests the relevance of alexithymia in patients suffering from HT, which may be intertwined with a possible state of underreported depression that is mainly expressed through physical complaints. Promoting the capability to describe and communicate feelings could contribute to psychological elaboration and coping with the disease and, consequently, to the improvement of self-management and perceived HRQoL.

The paper develops a phenomenology of hyper-reading (i.e. the act of reading hypertexts) moving from the prejudicial approach to such texts, developing the three moments of presence, boredom and authority and concluding with some remarks on the freedom of readers in the act of navigation of hypertexts – especially those on the Web.

We show that intuitionistic logic is deductively equivalent to Connexive Heyting Logic ($$\textrm{CHL}$$ CHL ), hereby introduced as an example of a strongly connexive logic with an intuitive semantics. We use the reverse algebraisation paradigm: $$\textrm{CHL}$$ CHL is presented as the assertional logic of a point regular variety (whose structure theory is examined in detail) that turns out to be term equivalent to the variety of Heyting algebras. We provide Hilbert-style and Gentzen-style proof systems for $$\textrm{CHL}$$ CHL ; moreover, we (...) suggest a possible computational interpretation of its connexive conditional, and we revisit Kapsner’s idea of superconnexivity.

This paper sheds light on the role of digital platform labour in the development of today’s artificial intelligence, predicated on data-intensive machine learning algorithms. Focus is on the specific ways in which outsourcing of data tasks to myriad ‘micro-workers’, recruited and managed through specialized platforms, powers virtual assistants, self-driving vehicles and connected objects. Using qualitative data from multiple sources, we show that micro-work performs a variety of functions, between three poles that we label, respectively, ‘artificial intelligence preparation’, ‘artificial intelligence verification’ (...) and ‘artificial intelligence impersonation’. Because of the wide scope of application of micro-work, it is a structural component of contemporary artificial intelligence production processes – not an ephemeral form of support that may vanish once the technology reaches maturity stage. Through the lens of micro-work, we prefigure the policy implications of a future in which data technologies do not replace human workforce but imply its marginalization and precariousness. (shrink)

The association of resilience-related factors with frailty is a recent research topic. Dispositional optimism and context sensitivity are two psychological factors that differently contribute to individual resilience. This study aimed at investigating whether dispositional optimism and context sensitivity might contribute to a multifactorial model of frailty, together with established relevant factors such as cognitive and physical factors. This cross-sectional study involved 141 elderly outpatients aged ≥65 years, who were referred to the Geriatrics and Multidimensional Evaluation Clinic of the University Hospital (...) of Messina. We used the following measures: the Mini-Mental State Examination to screen for global cognitive functioning; 4-m gait speed and handgrip strength to measure physical performance; a 35-item Frailty Index to evaluate patients’ frailty status; the revised Life Orientation Test to gauge dispositional optimism; and the Context Sensitivity Index to measure context sensitivity. We found that LOT-R, CSI, and MMSE were all significantly associated with FI. Gait speed was only marginally associated with FI. The present study showed a novel association of dispositional optimism and context sensitivity with frailty among elderly outpatients. These preliminary findings support a multidimensional approach to frailty in which even peculiar psychological features might provide a significant contribution. (shrink)

This work explores the later Wittgenstein’s philosophy of mathematics in relation to Lakatos’ philosophy of mathematics and the philosophy of mathematical practice. I argue that, while the philosophy of mathematical practice typically identifies Lakatos as its earliest of predecessors, the later Wittgenstein already developed key ideas for this community a few decades before. However, for a variety of reasons, most of this work on philosophy of mathematics has gone relatively unnoticed. Some of these ideas and their significance as precursors for (...) the philosophy of mathematical practice will be presented here, including a brief reconstruction of Lakatos’ considerations on Euler’s conjecture for polyhedra from the lens of late Wittgensteinian philosophy. Overall, this article aims to challenge the received view of the history of the philosophy of mathematical practice and inspire further work in this community drawing from Wittgenstein’s late philosophy.

We must undoubtedly take advantage of the benefits brought by new technologies, and we must apply them to the human being to the extent that a prolonged and serene reflection tells us that this application brings improvements in a full sense. But that does not mean that we should accept the ideological discourse of transhumanism. This discourse owes much of its power of conviction to certain philosophical assumptions that have not been sufficiently clarified and discussed. This article aims to highlight (...) some of them.

One of the most common ways of morphological marking is affixation, morphemes are classified according to their position. In languages with affixal morphology, suffixes and prefixes are the most common types of affixes. Despite several proposals, it has been impossible to identify solid generalisations about the behaviour of prefixes, in opposition to suffixes. This article argues that the reason is that our traditional definitions of suffix and prefix are based on pre-theoretical, surface criteria that have been given up in other (...) areas of linguistics: defining a morpheme as a prefix does not tell us anything about its grammatical nature, as that label does not take into consideration the structural configuration underlying the morpheme. Once the structural configuration is taken into account, solid generalisations begin to emerge. The article illustrates the advantages of this approach through a study of the interaction between vowel harmony and affixes. (shrink)

What is Aristotle's considered view of animal self-motion? According to several scholars, Aristotle ends up rejecting this very notion as a result of his criticism of Plato's theory of a self-moving soul. Contrary to this still widespread assumption, the present study argues that his critical engagement with Plato is not confined to negative results, but achieves largely positive outcomes, which add up to a rich and nuanced picture of self-motion. Ferro makes his case by offering a novel reading of a (...) handful of controversial passages from De Anima and Physics VIII, where Aristotle reacts to three aspects of Plato's theory of self-motion: the claim that soul itself is a self-mover, the assumption that self-movers enjoy strong causal autonomy, and the link between motion, desire and soul partition. Through a careful reading of the relevant passages, which does justice to their proper context and significance, Ferro shows that Aristotle's critical re-appropriation of self-motion results in a largely coherent doctrine with major repercussions for Aristotelian psychology and philosophy of nature.

This article seeks to problematize Agamben’s interpretation of sovereignty in light of the “archaeological method” he uses in his Homo Sacer project. In contrast to Agamben’s exposition, which treats biopolitics as the original and ontological paradigm of Western politics, the essay discusses how, historically, sovereign power has been conceived as a “double body”—transcendent and immanent, sacred and sacrificial, absolute and perpetual—from whose tension conceptual and political metamorphoses of sovereignty arise. The first attribute of sovereignty—absoluteness, on which Agamben has often focused—should (...) be seen as an ordering and essentially modern function of its second “body”: the perpetuity of power. The article illustrates, then, how the retrospective projections through which the Italian philosopher constructs his ontological reading of sovereignty depend on some logical and epistemological lacunae that characterize his “archaeological method,” which is based, essentially, on an arbitrary use of historical analogies.

Until now, the mass spread of fake news and its negative consequences have implied mainly textual content towards a loss of citizens' trust in institutions. Recently, a new type of machine learning framework has arisen, Generative Adversarial Networks (GANs) – a class of deep neural network models capable of creating multimedia content (photos, videos, audio) that simulate accurate content with extreme precision. While there are several areas of worthwhile application of GANs – e.g., in the field of audio-visual production, human-computer (...) interactions, satire, and artistic creativity – their deceptive uses, at least as currently foreseeable, are just as numerous and worrying. The main concern is linked to the so-called “deepfakes”, fake images or videos that simulate real events with extreme precision. When trained on a human face, GANs can make the face assume hyper-realistic movements, expressions and (verbal and non-verbal) communication abilities. This technology poses an urgent threat to the governance of democratic processes concerning the production of public opinions and political discourses, with significant potential for reality-altering and disinformation. After a short introduction of their current technical state-of-the-art, in this paper we want to enquire the GANs` socio-technical system alongside different and intertwined philosophical accounts. Firstly, we will argue about the conditions that make perceived a GANs-generated content as trustworthy, arguing also about the general effects GANs might have on the perceived trustworthiness of individuals. Thereafter, we will discuss about the inadequacy to approach GANs only as perception-altering technology. Against this backdrop, we will propose a theoretical turn that considers the human-machine relationships of trustworthiness as elements of a broader hybrid socio-technical systems. This turn come up with political repercussions that we will discuss in the last part of the paper. (shrink)
