The question of transtemporal identity of objects in general and persons in particular is an important issue in both philosophy and psychology. While the focus of philosophers traditionally was on questions of the nature of identity relation and criteria that allow to settle ontological issues about identity, psychologists are mostly concerned with how people think about identity, and how they track identity of objects and people through time. In this article, we critically engage with widespread use of inferring folk judgments (...) of identity from study participants’ use of proper names in response to experimental vignettes. We provide reasons to doubt that using this method one can reliably infer judgments of numerical identity over time and transformations. We also critically examine allegedly-Kripkean justification of this method and find it lacking. Merely assuming that names are rigid designators will not help. A study participant’s use of proper names can be taken to track the participant’s identity judgments only if supported by the participant’s belief that names used in the scenario are used rigidly.

In recent years modal syllogistic provided by 14th century logician John Buridan has attracted increasing attention of historians of medieval logic. The widespread use of quantified modal logic with the apparatus of possible worlds semantics in current analytic philosophy has encouraged the investigation of the relation of Buridan’s theory of modality with the modern developments of symbolic modal logic. We focus on the semantics of and the inferential relations among the propositions that underlie Buridan’s theory of modal syllogism. First, we (...) review all inferences between propositions of necessity, possibility, contingency, and non-contingency, with or without quod est locution, that are valid in Buridan’s semantics, and offer a comprehensive diagrammatic representation that includes them all. We then ask the question if there is a way to model those results in first order modal logic. Three ways of formalizing Buridan’s propositions in quantified modal logic are considered. Comparison of inferences between the quantified formulas and Buridan’s propositions reveals that, when supplied with a suitable formalization, Buridan’s semantics of categorical statements and immediate inferences among them can be fully captured by the quantified modal system T.

Formalizing categorical propositions of traditional logic in the language of quantifiers and propositional functions is no straightforward matter, especially when modalities get involved. Starting...

Šio straipsnio tikslas – bendrais bruožais aptarti reduktyvizmo raišką šiuolaikinėje analitinėje sąmonės, moralės, veiksmo ir priežastingumo filosofijoje bei įvertinti redukcijos strategijų šiose filosofijos šakose panašumus ir skirtumus. Straipsnyje aptariamos šešios reduktyvizmo strategijos – sąvokų sinonimija paremta redukcija, a posteriori tapatybės tezė, analitinis funkcionalizmas, anomalusis monizmas, analizė pasitelkiant pareities sąvoką, konceptualinė analizė be sąvokų sinonimijos – ir konstatuojama, kad skirtingose filosofijos srityse šios strategijos reiškiasi skirtingai, taip pat yra skirtingai kritikuojamos ir interpretuojamos. Straipsnyje mėginama paaiškinti kai kuriuos šių skirtumų ir daroma (...) išvada, kad šiuolaikinėje analitinėje filosofijoje neperspektyvu kalbėti apie reduktyvizmą apskritai, kaip vieną visas sritis apimantį reiškinį, paremtą visas reduktyvistines koncepcijas vienijančiu reduktyvizmo modeliu, forma ar vizija.

Straipsnyje analitinës filosofijos poþiûriu analizuojamas Descartes’o sàmonës ir kûno skirtingumo árodymas, siekiant atskleisti jo panaðumus su ðiuolaikinëje sàmonës filosofijoje populiariu Davido Chalmerso pateiktu „zombio“ mintiniu eksperimentu ir juo grindþiamu dualizmo árodymu. Siekiama parodyti, kad ðiuolaikinis modaline semantikos analize grindþiamas árodymo variantas yra techniðkai sudë-tingesnis ir atsparesnis fizikalistinei kritikai, taèiau jis paremtas nutylëta ir nepagrásta episteminio sà-vokø skaidrumo prielaida, kuri iðskirstina kaip viena originalaus dekartiðko árodymo silpnybiø.

The article raises the question what is the content of Frege’s infamous notion of Bedeutung? It is claimed that the so–called standard interpretation of this notion – Bedeutung as referential relation between a name and an object – was developed and established evaluating Frege’s ideas in philosophy of language in isolation from his logicist ideas. However, precisely his logicist concerns have motivated Frege’s interest in semantic issues. A broader consideration of Frege’s works reveals an internalist and rationalist notion of meaning, (...) that is based on the context principle, and that should not be reduced to mere reference. The question of the meaning of subsentential components, for Frege, is closely related to the question of the meaning of the whole sentence, that is, the meaning of sub–sentential components should be construed as secondary with regard to the meaning of the whole sentence.

The article analyzes John McTaggart’s argument for unreality of time, a classical piece of fin de siècleBrittish idealist metaphysics. Having accepted the distinction between A-series and B-series, one can only resist McTaggartian conclusion by denying at least one of the two: that B-series alone is insufficient for change or that A-series implies a contradiction. Hugh Mellor’s criticism is taken to represent thisstrategy. The lesson to be learnt from this debate is that if the world is conceived as a mere totality (...) of facts no change could be real in such a world, and so McTaggart would right. However, if the reality of things determining those facts is recognized as more fundamental, it would not be denied that at least some of these things undergo genuine temporal change, and time as a dimension of this real change cannot be rejected.

The paper analyses the relation between religion and morality. It is argued that absolutistic theistic conception of morality, which transforms metaphysical issues into moral ones, despite being the most popular folk understanding of morality, is neither the only one possible nor the most effective one. Accepting Bernard Williams‘ remark that religion in the context of morality adds either nothing or a wrong sort of thing, a conclusion is drawn that philosophical issues of morality can and should be considered in isolation (...) from religious issues.

The paper is devoted to a discussion and critical evaluation of antisceptical arguments in epistemology that are based on causal theory of reference, with the special focus upon the revised version of the Hilary Putnam‘s Brain-in-a-Vat argument presented by Olaf Müller. Müller claims that his argument is based on the metaphysically neutral principles of semantic externalism and disquotation, however more thorough analysis of these principles and of the possibility to use them for antisceptical purposes reveals the flaw in his argument. (...) It seems that Müller reaches his conclusion by confusing the syntactically identical, though semantically distinct utterances in BIV language, non-BIV language, and metalanguage. The reconstruction and analysis of Müller‘s argument shows that his argument, provided that its premises are formulated carefully so as not to beg the question against the sceptic, fails to establish anything more than the original version provided by Putnam.Keywords: scepticism, Olaf Müller, semantic externalism, disquotation, brain-in-a-Vat.

The most urgent challenge of this year – the COVID-19 pandemic and measures of response to it – has sharpened and accelerated the process which was initially driven by bureaucratization and formalization: increasing depersonalization of academic life and the erosion of the university as a unique form of coexistence. The Assuming the concept of the university as a value category, this article aims to review and assess the changes in the self-perception of the academic community that have matured and acquired (...) institutional forms in an attempt to adapt to rapidly shifting societal expectations and needs. Modern trends in university development are best expressed in terms such as “bureaucratization”, “formalization”, “depersonalization”, “instrumentalization of knowledge”, and “community fragmentation”. The pandemic of effective management that has affected Western universities and has gradually reached Vilnius University, no less than the pandemic of COVID-19 and administrative response to it, weakens the academic community based on autonomous and collegial decisions, which should be considered among the most important grounds of uniqueness of university as an institution.

Straipsnyje nagrinėjama analitinės kalbos ir mokslo filosofijos raida Lietuvoje. Konstatuojama, kad analitinė filosofija Lietuvoje pradėta plėtoti XX amžiaus aštuntajame dešimtmetyje, kai Evaldas Nekrašas ir Rolandas Pavilionis paskelbė savo pirmųjų mokslo filosofijos ir kalbos filosofijos tyrinėjimų, kuriuose remiamasi analitine tradicija, rezultatus. Straipsnyje analizuojami jų ir kitų tyrėjų, kurie rėmėsi ta pačia tradicija, pirmiausia Algirdo Degučio ir Albino Plėšnio darbai. Analitinė filosofija buvo pirmoji nemarksistinės filosofijos kryptis, pradėta plėtoti pokarinėje Lietuvoje, todėl aštuntajame ir devintajame dešimtmečiuose ji atliko svarbų vaidmenį plečiant šalyje filosofinių (...) tyrinėjimų tematiką ir keičiant jų metodologinius pagrindus. Nors pastaruoju metu jos įtaka Lietuvos filosofijoje kiek sumažėjo, ji aiškiai juntama kai kuriuose pastarojo meto darbuose, kuriuose nagrinėjamos sąmonės filosofijos, priežastingumo, humanitarinių ir socialinių mokslų metodologijos problemos. Ji padarė nemažą poveikį ir pozityvizmo raidos bei politinės filosofijos problemų tyrimui. Pagrindiniai žodžiai: Lietuvos filosofija, analitinė filosofija, kalbos filosofija, mokslo filosofija, pozityvizmas. (shrink)
