Starting from the sixties of the past century theory change has become a main concern of philosophy of science. Two of the best known formal accounts of theory change are the post-Popperian theories of verisimilitude (PPV for short) and the AGM theory of belief change (AGM for short). In this paper, we will investigate the conceptual relations between PPV and AGM and, in particular, we will ask whether the AGM rules for theory change are effective means for approaching the truth, (...) i.e., for achieving the cognitive aim of science pointed out by PPV. First, the key ideas of PPV and AGM and their application to a particular kind of propositional theories - the so called "conjunctive propositions" - will be illustrated. Afterwards, we will prove that, as far as conjunctive propositions are concerned, AGM belief change is an effective tool for approaching the truth. (shrink)

We propose a view of consciousness as a sort of metaphoric “funnel” transforming a fraction of the parallel processes taking place continually in our central nervous system into something intrinsically serial and sequential. A conscious state is the result of this temporary serialization of a set of parallel mental processes. Before this event, everything is parallel, but also after it, everything returns parallel. As a consequence, the simile we propose is that of a “clepsydra” or sandglass. A conscious state coincides (...) with its bottleneck. Here, we explore possible consequences of the adoption of this model. (shrink)

This work intends to be a generalization and a simplification of the techniques employed in [2], by the proposal of a general strategy to prove satisfiability theorems for NLGM-s (= normal logics with graded modalities), analogously to the well known technique of the canonical models by Lemmon and Scott for classical modal logics.

Henri de Lubac is not a philosopher, but has some well -thought out philosophical beliefs, many of which derived from Blondel.

Conoscere non riguarda solo l'intelligenza, ma anche l'affettività e un insieme di fattori extra-teoretici (=non meramente conoscitivi o intellettuali). In particolare una certezza esistenzialmente forte sui problemi filosofici decisivi non può essere raggiunta senza un coinvolgimento della libertà, in una “esperienza integrale”.

This paper clarifies why and how Wittgenstein’s animating idea of social practices should be considered as expressing a fundamental pragmatist commitment.To this end, I do not take the retrospective perspective, which traces “pragmatism” back to the criteria of use fixed by the inventor of the word, C. S. Peirce, but rather replace Wittgenstein in the context of contemporary debates. I focus in particular on R. Brandom’s attempt to understand Wittgenstein’s second philosophy as belonging to an intellectual tradition from which his (...) own rationalist pragmatism derives. A confrontation follows between Brandom and Wittgenstein, whose aim is to highlight the specific tactics of Wittgenstein’s pragmatism as a refusal of Brandom’s idealist rationalism. First, I present and defend R. Brandom’s reading of Wittgenstein’s argument on rule-following as a decisive clarification of the general idea of social practices. Second, I criticize Brandom’s narrow Kantian framework, explaining why it prevents us from understanding Wittgenstein’s conception of rules and concepts, and, therefore, of the very normativity of concepts. In light of the distinction between two kinds of conceptual norms, empirical and grammatical, I finally show, through a reading of On certainty, that the function assigned by Wittgenstein to social practices is to account for the conditions of possibility of conceptual contentfullness as expressed in rational activity.

The aim of the present paper is twofold. First, we are interested in assessing the validity of one version of Kim’s argument against genuine higher level causation. Second, we discuss Wilson’s proposal to consider a weaker notion of emergence as genuinely metaphysical and compatible with Non-Reductive Physicalism. Our conclusion is that both proposals fail: the first in preempting genuine (strong) emergent causation, whereas the second in ensuring a genuinely metaphysical status to weak emergence. After all, Wilson’s proposal strongly depends on (...) the success of Kim’s, not only because it takes it as valid but, also, because in pursuing its own weaker model it shares the presuppositions that led Kim’s to failure. At the end of the day, Wilson’s conception of genuine weak emergence either breaks causal closure or is merely stipulative, namely confined at the descriptive level. (shrink)

Expressively equivalent logical languages can enunciate logical notions in notationally diversified ways. Frege’s Begriffsschrift, Peirce’s Existential Graphs, and the notations presented by Wittgenstein in the Tractatus all express the sentential fragment of classical logic, each in its own way. In what sense do expressively equivalent notations differ? According to recent interpretations, Begriffsschrift and Existential Graphs differ from other logical notations because they are capable of “multiple readings.” We refute this interpretation by showing that there are at least three different kinds (...) of such multiple readings. While readings of the first kind do not capture any essential difference among notations but only among vocabularies, corresponding to readings of the second and the third kind two general parameters according to which notations may differ are defined: linearity vs. non-linearity, and tabularity vs. non-tabularity. This answers the question of how there can be substantially different but expressively equivalent logical notations. (shrink)

According to Chomsky, creativity is a critical property of human language, particularly the aspect of ?the creative use of language? concerning the appropriateness to a situation. How language can be creative but appropriate to a situation is an unsolvable mystery from the Chomskyan point of view. We propose that language appropriateness can be explained by considering the role of the human capacity for Mental Time Travel at its foundation, together with social and ecological intelligences within a triadic language-grounding system. Our (...) proposal is based on the change of perspective from the analysis of individual sentences to the flux of speech in which the temporal dimension of language is much more relevant. (shrink)

The article proposes a re-examination of the role and position of the so-called “Disney villains” within the narrative framework of animated films and popular culture as a whole. In the first part, the historical evolution in the representation of these villains will be explored according to the practice of “queer coding,” which involves attributing stereotypically queer traits to them without explicitly stating their gender and sexual identity. It will be observed how their non-conforming gender and sexuality, used to mark their (...) moral deviance, challenge and defy dominant gender and narrative norms. It is precisely through their queer performance and camp aesthetic that “evil stepmothers,” “sissy-villains,” and “drag-queen-like” sea witches can emancipate themselves from their traditional roles as antagonists (narrative level) and as social outcasts (discursive level) to seize the spotlight through the screen (manifest surface). This study combines tools of Greimasian text analysis, including the canonical narrative schema and the generative trajectory of meaning, with Lotman’s theory and notion of “semiosphere,” to investigate the centrality and criticality of these “quillains” within the heteronormative narrative framework and the broader cultural context. To capture (or being captured by) the queer aspect of these characters and their stories, the invitation is to look at their visage not as a coded symbol of an underlying identity and truth, but as an image that exceeds any defined meaning thanks to its iconic power.

The present paper argues that substantialist metaphysics are in tension with the physicalist idea that the universe is causally closed. The argument is a rather specific one and proceeds through three steps. The first step consists in arguing that monistic substance metaphysics allow for the existence of entities that cannot belong to the intended first order domain. This result sensitively depends on the nature of substances as invariant entities. The second step concludes that, if further domains are to be admitted, (...) then they are inhabited by “higher” or (systematically) “non-standard” entities and that, in both cases if not made somehow innocuous, such entities may take part on the metaphysical construction of the world through their own distinctive properties and causal powers. However, this latter claim is in contradiction with causal closure. But closure is the principle that mainly characterizes physicalist approaches in metaphysics and as such physicalist metaphysics cannot get rid of it. Who attempted making exotic properties and causal powers innocuous usually appealed to the Supervenience Argument. Unfortunately, as the third step proves, this argument is invalid. Finally, the paper looks forward and toward alternative models for physicalist metaphysics, like process-based models. (shrink)

Corporate social responsibility (CSR) is becoming a mainstream issue as both researchers and managers are realizing its importance, but knowledge gaps persist. In particular, the processes underlying the adoption of responsible managerial practices and the effects associated with them are still at the centre of intense debate. Not surprisingly, managers expect formalized procedures that might influence corporate managerial processes and especially corporate strategies. Given the growing emphasis on the integration of CSR into corporate strategy, the purpose of this qualitative study (...) is to explore the antecedents of this process and the dynamics underlying it. We focus on a medium-sized, family-owned Italian company, SABAF SpA. We find that: the beliefs and value systems of entrepreneurs play a fundamental role in shaping a sustainable corporate strategy; the importance of the relationship between social performance and financial performance depends to some extent on the kind of competitive strategy that a company has selected; and people need to be aware of it – that is, CSR strategies must be explicit and codified into specific managerial procedures.

As Artificial Intelligence (AI) becomes more and more pervasive in our everyday life, new questions arise about its ethical and social impacts. Such issues concern all stakeholders involved in or committed to the design, implementation, deployment, and use of the technology. The present document addresses these preoccupations by introducing and discussing a set of practical obligations and recommendations for the development of applications and systems based on AI techniques. With this work we hope to contribute to spreading awareness on the (...) many social challenges posed by AI and encouraging the establishment of good practices throughout the relevant social areas. As points of novelty, the paper elaborates on an integrated view that combines both human rights and ethical concepts to reap the benefits of the two approaches. Moreover, it proposes innovative recommendations, such as those on redress and governance, which add further insight to the debate. Finally, it incorporates a specific focus on the Italian Constitution, thus offering an example of how core legislations of Member States might contribute to further specify and enrich the EU normative framework on AI.

In recent years, the concept of the border has undergone profound transformations and become central to a broad debate investigating the complexity of its political and social practices. The centrality of the border topic in public debate has contributed to the development of something akin to a “frontier cinema” or, better, a propensity for “filming at the border.” This essay investigates political borders as media environments and seeks to develop the idea of the “border mediascape” as a new framework at (...) the crossroads of multiple disciplines. A documentary film shot on the island of Lampedusa during the so-called European migrant crisis, the award-winning and critically acclaimed Fuocoammare ( Fire at Sea, 2016) by Gianfranco Rosi, is used as a case study to reflect on the functioning of technological devices placed along borders and, thus, on the geopolitics of environmental media. The original take this documentary offers on the media devices that operate along national borders—as well as on the environmental, social, and political effects of those technologies—is an aspect that has gone unnoticed by critics. Watching this film through the eyes of media and border studies provides the opportunity to conceive contemporary national borders as a form of geopolitical asymmetry implanted in media technology.

Cet article propose une reconstruction du débat sur la nature du plaisir qui eut lieu dans l’ancienne Académie à partir du témoignage d’Aristote dans l’ Éthique à Nicomaque. Ce sont notamment les positions attribuées à Eudoxe et Speusippe qu’Aristote discute et critique dans la perspective da sa propre conception du plaisir. La présentation d’Aristote est ensuite mise en relation avec le Philèbe, qui rapporte vraisemblablement le point de vue de Platon sur ce débat et sa version des différents arguments que (...) les protagonistes développèrent.

The thin red line theory is a form of branching indeterminism. It entails that, among the many possible developments that reality might take, one is privileged: the actual history. The thin red line theory is naturally paired off with a semantic thesis that may be called ‘the actuality principle’: a statement is true as used at a moment if and only if it is true at that moment on the actual history. The actuality principle has been challenged, for it would (...) be wrong about several counterfactual reasonings. On the one hand, the actuality principle should entail that any statement uttered at a merely possible moment is untrue. On the other hand, the actuality principle should be at odds with the way we use subjunctive conditionals. This paper argues that both objections rely on an inadequate understanding of the notion of the history of use. As for the first objection, the paper argues that to assume the actuality principle amounts to taking the actual history as the history of use. As a consequence, one cannot consistently take the actual history as the history of use and, at the same time, a merely possible moment as the moment of use. As for the second objection, the paper shows that the actuality principle is consistent with any reasonable treatment of subjunctive conditionals. (shrink)

This commentary focuses on three aspects of Sandro Nannini’s paper Time and Consciusness in Cognitive Naturalism: the parallel between Einstein’s theory of relativity and the new science of the mind/brain; the Cartesian characterization of non-reductionist positions in the philosophy of mind; the alleged illusory status of consciousness, free will and the Self. We suggest, first, that Nannini overstates the success of cognitive neuroscience; second, that non-reductionism is not necessarily a Cartesian position; and third, that the neurocognitive science data do not (...) show or even suggest, that consciousness, free will and the Self are illusory phenomena.
