In this article, we reflect on the use of formal methods in the philosophy of science. These are taken to comprise not just methods from logic broadly conceived, but also from other formal disciplines such as probability theory, game theory, and graph theory. We explain how formal modelling in the philosophy of science can shed light on difficult problems in this domain.

This paper combines propositional dynamic logic ) with propositional inquisitive logic ). The result of this combination is a logical system \ that conservatively extends both \ and \, and, moreover, allows for an interaction of the question-forming operator from \ with the structured modalities from \. We study this system from a semantic as well as a syntactic point of view. These two perspectives are linked via a completeness proof, which also shows that \ is decidable.

Traditionally, epistemologists have held that only truth-related factors matter in the question of whether a subject can be said to know a proposition. Various philosophers have recently departed from this doctrine by claiming that the answer to this question also depends on practical concerns. They take this move to be warranted by the fact that people’s knowledge attributions appear sensitive to contextual variation, in particular variation due to differing stakes. This paper proposes an alternative explanation of the aforementioned fact, one (...) that allows us to stick to the orthodoxy. The alternative applies the conceptual spaces approach to the concept of knowledge. With knowledge conceived of spatially, the variability in knowledge attributions follows from recent work on identity, according to which our standards for judging things (including concepts) to be identical are context-dependent. On the proposal to be made, it depends on what is at stake in a context whether it is worth distinguishing between knowing and being at least close to knowing. (shrink)

The construction industry consistently ranks amongst the highest contributors to global gross domestic product, as well as, amongst the most corrupt. Corruption therefore inflicts significant risk on construction activities, and overall economic development. These facts are widely known, but the various sources and nature of corruption risks endemic to the Iranian construction industry, along with the degree to which such risks manifest, and the strength of their impact, remain undescribed. To address the gap, a mixed methods approach is used; with (...) a questionnaire, 103 responses were received, and these were followed up with semi-structured interviews. Results were processed using social network analysis. Four major corruption risks were identified: procedural violations in awarding contracts, misuse of contractual arrangements, neglect of project management principles, and, irrational decision making. While corruption risks in Iran align with those found in other countries, with funds being misappropriated for financial gain, Iran also shows a strong inclination to champion projects that serve the government’s political agenda. Root cause identification of corruption risks, namely, the noticeable impact of authoritarianism on project selection in Iran, over criterion of economic benefit or social good, is a significant outcome of this study.

The present paper discusses the problem of quantum-mechanical properties of a subject’s consciousness. The model of generalized economic measurements is used for the analysis. Two types of such measurements are analyzed – transactions and technologies. Algebraic ratios between the technology-type measurements allow making their analogy with slit experiments in physics. It has been shown that the description of results of such measurements is possible both in classical and in quantum formalism of calculation of probabilities. Thus, the quantum-mechanical formalism of the (...) description of states appears as a result of idealization of the selection mechanism in the proprietor's consciousness. (shrink)

Michel Tournier was a philosopher before being a novelist. And even when he decided to become a novelist, he introduced himself as a « smuggler of philosophy ». But it is impossible to take full measure of this statement without considering the one and only philosophical text he ever published, in 1946: « L’Impersonnalisme ». This article, which he considered to be his « system of the world », is here presented in its historical and philosophical context.

Through the analysis of certain aspects of Leonardo Bruni’s language, and in particular his use of “popolo” and “res publica”, we strive to understand the extent to which the politics of the early humanists remained rooted in the recent past of the City of Florence, despite the obvious ideological innovations (and without considering those of a stylistic and literary nature). Bruni seems to have inherited the primacy and unity of the Florentine people directly from the discourses of the 14th-century jurists. (...) On the other hand, “respublica” turns out to be, in his texts, both an entirely traditional notion and the emblem of the process of essentialisation of a people reconstituted in its universal dimension thanks to the definitive expulsion of conflict from the horizon of possibilities. At the same time, in a dialogue with Claudia Moatti in particular, we try to ascertain how, with which tools, some research on Roman history helps us grasp the metamorphoses of the ‘people’ in a much later period.

Introduction. Modern times are characterized by independence from financial support for travel due to introducing an ordinary region with its daily surrounding into tourist circulation, focusing not on distance, but on the depth of emotions when choosing a place to visit. The aim of the study is to assess the factors of transforming the tourist environment in a region, which might result in a number of challenges for managing the regional development. Methods. In the framework of the study, both general (...) logical methods and empirical methods are used. In particular, the analysis of approaches to managing a tourist region in the post-tourism era, as well as new tourist practices are based on classification and periodization. When choosing the factors of the tourist region new format, the case method and comparison were applied. The scientific novelty of the study. The authors substantiate that the new era will be determined by changes in the labor–leisure ratio, new tourist practices and new tourist region format. The new tourist region format involves a transition to understanding the tourist as a temporary resident of the region and actualizes the need for coexistence. Results. The state of post-tourism for such a region may be due to the emergence of new residentsowners of second homes and business migrants, as well as the social effect of deliberate tourism practices. The competition of such regions is based on intangible resources. The factors of transforming the tourist environment made it possible to give a new look at assessing the effectiveness of an event for the territory. The authors propose threshold values that will allow making decisions on the co-financing of the event from the regional or local budget. Conclusions. Hybridization of tourism and leisure does not provide a complete answer about a possible reduction in work hours, however, indicates a short-term leisure mobility of individuals. New tourism practices are based on awareness and desire to increase self-efficacy. Such transformations open up new opportunities for the territory development. (shrink)

Explora as noções deleuzinas sobre o cinema e problematiza elementos relacionados a indexação de filmes. Aprofunda as questões cinematográficas trabalhadas por Deleuze, que concebe dois principais regimes de imagens, compreendidos no cinema clássico e no cinema moderno. O cinema clássico é fundado na imagem-movimento, a qual submete o tempo à ação, já o cinema moderno, caracteriza-se pela imagem-tempo, a qual desvincula tempo e movimento e revela situações óticas e sonoras puras. Analisa o problema do tempo em três filmes dirigidos por (...) Michelangelo Antonini, conhecidos como trilogia da incomunicabilidade, A Aventura (1960), A Noite (1961) e O Eclipse (1962). A partir da análise de filmes sob a abordagem deleuziana é possível ampliar as dimensões presentes na indexação, tanto no processo de leitura quanto de análise do documento, considerando a dimensão do afeto.

Em O Niilismo, Volpi Franco discorre sobre a história do niilismo e problematiza temas contemporâneos como o fim da história, o relativismo e o ceticismo.

Aborda o conceito filosófico de rizoma na teorização de Gilles Deleuze e Félix Guattari para desfazer mal entendidos na literatura recente de Ciência da Informação. Explana a dinâmica de criação conceitual na Filosofia e na Ciência, entendendo-as como movimentos entre o virtual e o atual. Em seguida aborda o deslizamento de planos entre Filosofia, Arte e Ciência para ser possível compreender a absorção do conceito filosófico de rizoma pela Ciência da Informação. Apresenta a organização e fluxo da informação pensados inicialmente (...) com a noção de árvore caminhando mais recentemente para a noção de rizoma ou rede. Por fim aproxima as teorizações da filosofia da diferença e da análise de discurso da escola francesa para iluminar ainda mais os mal entendidos sobre a transposição conceitual na Ciência da Informação.

A noção de informação cristalizou-se na área sob uma perspectiva da Teoria Matemática da Informação, sob o enfoque da comunicação, todavia, essa não é a única semântica possível. Gilbert Simondon utiliza o conceito de informação como elemento envolvido no processo de individuação. Em diálogo com a filosofia de Deleuze e as contribuições do pesquisador Faucher este ensaio explora a ontologia de Simondon a fim que recolocar o conceito de informação à Ciência da Informação. Para Simondon não há indivíduo físico, biológico, (...) psíquico ou social sem informação. A informação implica o devir da e na matéria. Sob tal fundamentação, a Ciência da Informação realiza-se no ciclo virtual-intensivo-atual enquanto segue a materialidade que devém na medida em que se informa e se individualiza. À Ciência da Informação é aberta a possibilidade de pensar a informação enquanto força intensiva sobre um plano imanente. (shrink)

Various authors have recently argued that you cannot rationally stick to your belief in the face of known disagreement with an epistemic peer, that is, a person you take to have the same evidence and judgmental skills as you do. For, they claim, because there is but one rational response to any body of evidence, a disagreement with an epistemic peer indicates that at least one of you is not responding rationally to the evidence. Given that you take your peer (...) to have the same judgmental skills as you do, and thus regard her to be equally good at assessing the evidence as you are, you will have as much reason for thinking that it is you who is not responding rationally to the evidence as for thinking that it is her. You thus have reason for thinking that your belief on the disputed matter is not a rational response to the evidence. Hence, you cannot rationally stick to your belief. (shrink)

The question, whether there is a sharp difference between an analytic and a synthetic proposition, is one of the famous philosophical topics of the 20th century. The question, however, urges one to ask following questions: "What is an analytic proposition?", or „What is a synthetic proposition?“. The aim of the paper is to contribute to the discussions of the analyticity in that it tries to answer the first of the two. However, the author does not offer his own conception of (...) analyticity. He rather offers a more detailed view on the definitions and characteristics of an analytic proposition in Kant and Frege.

A defense of the rationality of adductive inference from the criticisms of Bayesian theorists.

This paper argues that pragmatic considerations similar to the ones that Grice has shown pertain to assertability pertain to acceptability. It further shows how this should affect some widely held epistemic principles. The idea of a pragmatics of belief is defended against some seemingly obvious objections.

The paper introduces a new kind of models for the logic of proofs LP, the group justification models. While being an elaboration of Fitting models, the group justification models are a special case of the models of general awareness. Soundness and completeness results of LP with respect to the new semantics are established. The paper also offers an interpretation of the group models, which pertains to awareness and group epistemic dynamics.

L'œuvre de Deleuze et Guattari est une philosophie des devenirs-révolutionnaires, qui est à la fois ancrée dans son époque et en rupture avec elle. Dans L'Anti-Œdipe et Mille plateaux, Deleuze et Guattari veulent en effet : théoriser le potentiel révolutionnaire qui s'est manifesté en Mai 68 et qui a rouvert les possibles dans l'histoire, par une combinaison originale de révolution sociale et de révolution désirante (théorie des minorités) ; analyser les conditions qui ont permis le retournement de ce moment révolutionnaire (...) en une vaste contre-révolution mondiale, avec les nouvelles formes de répression des minorités (théorie du néo-fascisme) ; et déterminer les moyens d'élargir la brèche ouverte dans l'histoire par le mouvement de Mai 68 et contribuer à dresser l'organisation révolutionnaire qui lui a fait défaut (théorie de la machine de guerre minoritaire et révolutionnaire). S'exprime là tout un effort pour revitaliser les forces sociales et en libérer le potentiel révolutionnaire. Cet horizon n'est-il pas encore le nôtre?"--Page 4 of cover. (shrink)

The article is based on own methods of tourist estimation of historical and cultural potential of castle buildings in the Ivano-Frankivsk region to determine their level of attractiveness and prospects for needs of tourism and recreation industry. In the Ivano-Frankivsk region are five castles: in Halych Mariiampil, Rakovets, Chernelytsia and Pniv, which have great historical and cultural potential and all of these buildings can be used for the tourist adaptation. Criteria of the tourist estimation of potential of castle complexes are (...) built on an integrated approach that includes four groups of indicators: the natural and geographical location, historical and cultural features, infrastructure and advertising criteria. The tourist analysis of historical and cultural potential of castle constructions in the Ivano-Frankivsk region showed that 4 castles are at an average level of tourist adaptation and just castle in Halych has higher level of tourist and recreational adaptation. The author proposed following options for optimizing of the recreational use of castles, which are based on the tourist estimation: organization of new event activities, development of new tourist and recreational routes with castles and museumification.
