The author proposes that the anonymous letter dated May 19, 1641, which Mersenne delivered to Descartes, should be attributed to Thomas Hobbes. Although the text is known, it is usually considered not so much in itself as for Descartes’s two replies, which contain important clarifications on the proof of God’s existence. Hobbes’ hand is revealed by various thematic, conceptual, and lexical analogies and, above all, by the presence of two doctrines characteristic of his thought: 1) the denial of the existence (...) of intellectual ideas; 2) the assertion that the nature of God can only be described by the proposition “God exists”. Attribution to Hobbes of the May 19 th 1641 letter throws new light on the debate that followed Descartes’s Meditations as well as on Mersenne’s role. (shrink)

Classical first-order logic \ is commonly used to study logical connections between statements, that is sentences that in every context have an associated truth-value. Inquisitive first-order logic \ is a conservative extension of \ which captures not only connections between statements, but also between questions. In this paper we prove the disjunction and existence properties for \ relative to inquisitive disjunction Open image in new window and inquisitive existential quantifier \. Moreover we extend these results to several families of theories, (...) among which the one in the language of \. To this end, we initiate a model-theoretic approach to the study of \. In particular, we develop a toolkit of basic constructions in order to transform and combine models of \. (shrink)

In this paper, we report on the development of The Sustainable Port video game, which aims to simulate the complex dynamics and decisions occurring in the present and future development of a port area considering environmental aspects (CO2 emissions) and profit. To evaluate if this game fulfills its purpose, we asked 75 students and 34 employees at the Port of Rotterdam (PoR) to play The Sustainable Port. Our results show that PoR employees score higher than students suggesting a transfer between (...) real-life experience of being an employee in the port and performance in the game. Furthermore, port participants reported that The Sustainable Port can be successfully used to start discussions about the future of the Port of Rotterdam and to raise awareness about the complexity characterizing the decision-making processes occurring in a port environment. Our results, taken together, provide evidence of the effectiveness of The Sustainable Port in simulating dynamics occurring in port development and give us optimism about future applications.

What does it mean “knowing through art”? This paper develops an approach of radical cognitivism, suggesting a new way of integrating aesthetics and cognitive sciences.

I propose that artworks represent a specific and homogeneous ontological kind, grounded in a common ontological core. I call this common core ‘non-universalizable embodied meaning’, and I argue that this common core explains how artworks unfold their ontological identity at the physical, intentional, and social levels on the basis of an original and irreducible mode of material embodiment and cultural emergence; this common core functions as the constitutive rule of art and institutes an axiological normativity, that is, normativity based on (...) aesthetic value; it has a central role both in the theoretical definition of art and in the identification, recognition, and fruition of the individual artworks; it enables artistic creativity, historical transformations of art, and the current, multifaceted state of art.

We show that a form of dependence known as G-dependence admits a very natural finite axiomatization, as well as Armstrong relations. We also give an explicit translation between functional dependence and G-dependence.

Gianluca Di Muzio develops a novel objection to theism.

In this article, we discuss the issue of context-dependence of mechanism-based explanation in the social sciences. The different ways in which the context-dependence and context-independence of mechanism-based explanation have been understood in the social sciences are often motivated by different and apparently incompatible understandings of what explanatory mechanisms are. Instead, we suggest that the different varieties of context-dependence are best seen as corresponding to different research goals. Rather than conflicting with one another, these goals are complementary to each other and (...) therefore pave the way to a methodologically more cooperative approach to mechanism-based explanation in the social sciences.

Pierre Bayle (1647–1706) is often considered one of the staunchest defenders of toleration, especially in the domain of religion. His Commentaire philosophique, published in 1686, one year after the revocation of the Edict of Nantes, argued for a broad idea of toleration, to be extended with no exceptions to all sects and religions. However, his thought can hardly be reduced to an exaltation of the “rights of the conscience,” for he realized very soon that such an exaltation risks bringing forth (...) religious fanatism, which in turn is the cause of religious wars and acts of violence. Toleration, in these conditions, is only a political remedy for the sickness of the human mind. (shrink)

L'opera di Primo Levi presenta un caso straordinariamente ricco e in qualche modo enigmatico di intertestualità. Con questo volume si è cercato di tracciare i lineamenti di una mappa immaginaria, uno schema degli innesti, intertesti e trapianti che collegano l'opera leviana ai libri altrui.

Nella conferenza su Le cinéma et la nouvelle psychologie Merleau-Ponty introduce una singolare, ma decisiva notazione sull’arte filmica, legandola alla nozione di “ritmo”. Tale nozione dà avvio a una riflessione sull’immagine e sul rapporto tra l’immagine e lo sguardo dello spettatore al cinema. Nel presente articolo, l’uso che Merleau-Ponty ne fa e il senso di questa operazione saranno letti in riferimento alla riflessione di Émile Benveniste sul ritmo e ad alcune annotazioni contenute nei corsi di Merleau-Ponty al Collège de France, (...) di qualche anno successivi alla conferenza, su Le monde sensible et le monde de l’expression e quello sulle Recherches sur l’usage littéraire du langage. Dans le texte de sa conférence sur Le cinéma et la nouvelle psychologie, Merleau-Ponty introduit une lecture, singulière mais décisive, de l’art filmique, en la rapprochant de la notion de « rythme ». Cette notion engage une réflexion sur l’image et sur le rapport entre l’image et le regard du spectateur au cinéma. Dans cet article, l’utilisation que Merleau-Ponty en fait et le sens de cette opération seront lus à partir de la réflexion d’Émile Benveniste sur le rythme et à partir de certaines notes présentes dans les cours de Merleau-Ponty au Collège de France sur Le monde sensible et le monde de l’expression et sur les Recherches sur l’usage littéraire du langage, qui suivent de quelques années la conférence.In the text of his lecture on “Film and the new psychology,” Merleau-Ponty introduces a singular and decisive reading of filmic art, approaching the notion of “rhythm.” This notion engages in a reflection on image and on the relation between the image and the gaze of the spectator at the cinema. In this article, Merleau-Ponty’s actual usage of this notion and the meaning of this operation will be read starting from the reflection of Émile Benveniste on rhythm as well as certain notes presented in Merleau-Ponty’s courses at the Collège de France on The sensible world and the world of expression and Research on the literary usages of language, that follow some years after the lecture.

We prove that every quasi-Hopfian finitely presented structure _A_ has a _d_- \(\Sigma _2\) Scott sentence, and that if in addition _A_ is computable and _Aut_(_A_) satisfies a natural computable condition, then _A_ has a computable _d_- \(\Sigma _2\) Scott sentence. This unifies several known results on Scott sentences of finitely presented structures and it is used to prove that other not previously considered algebraic structures of interest have computable _d_- \(\Sigma _2\) Scott sentences. In particular, we show that every (...) right-angled Coxeter group of finite rank has a computable _d_- \(\Sigma _2\) Scott sentence, as well as any strongly rigid Coxeter group of finite rank. Finally, we show that the free projective plane of rank 4 has a computable _d_- \(\Sigma _2\) Scott sentence, thus exhibiting a natural example where the assumption of quasi-Hopfianity is used (since this structure is not Hopfian).

Following the guiding thread of Peirce’s use of diagrammatic syntax in his system of existential graphs , which depends crucially on the role of the Sheet of Assertion, we introduce the notion of Sheet of Indication as the basis for a general diagrammatic semantics applicable to a wide range of diagrams. We then show how Peirce’s EG-alpha graphs may be understood as instances of SIs and how logically coherent models of the graphs are represented in the SI semantics.
