Jacek Urbaniec: Platonism in the philosophy of mathematics does not necessarily imply that there are links between the temporal physical world and the eternal world of mathematics..

The purpose of the paper is to rethink the role of actuality in the branching model of possibilities. We investigate the idea that the model should be enriched with an additional factor—the so-called Thin Red Line—which is supposed to represent the single possible course of events that gets actualized in time. We believe that this idea was often misconceived which prompted some unfortunate reactions. On the one hand, it suggested problematic semantic models of future tense and and on the other, (...) it provoked questionable lines of criticism. We reassess the debate and point to potential pitfalls, focusing on the semantic dimension of the Thin Red Line theory. Our agenda transcends the semantics, however. We conclude that semantic considerations do not threaten the Thin Red Line theory and that the proper debate should be carried in the domain of metaphysics. (shrink)

In this paper we present a characterization of hyper-connexivity by means of a relating semantics for Boolean connexive logics. We also show that the minimal Boolean connexive logic is Abelardian, strongly consistent, Kapsner strong and antiparadox. We give an example showing that the minimal Boolean connexive logic is not simplificative. This shows that the minimal Boolean connexive logic is not totally connexive.

We prove that no logic (i.e. consequence operation) determined by any class of orthomodular lattices admits the deduction theorem (Theorem 2.7). We extend those results to some broader class of logics determined by ortholattices (Corollary 2.6).

Johann Wilhelm Andreas Pfaff (1774-1835) był obiecującym niemieckim matematykiem i astronomem, należącym do bogatej w tradycje akademickie rodziny Pfaffów – miał dwóch starszych powszechnie znanych braci. Niniejszy artykuł przedstawia życie najmłodszego z Pfaffów – od czasu jego studiów teologicznych w Getyndze do okresu działalności w Uniwersytecie Erlangeńskim. Krocząc śladami Klaudiusza Ptolemeusza i Johanna Keplera, Johann Wilhelm Andreas Pfaff usiłował promować astrologię w pierwszych dekadach XIX wieku. Jego wysiłki umocnienia astrologii jako pełnoprawnej dyscypliny akademickiej, zamiast oczekiwanego skutku, spotkały się z opozycją, (...) drwiną i marginalizacją samego Pfaffa w ówczesnej społeczności akademickiej. Jednakże jego osobisty dramat powinno się umiejscowić w szerokim kontekście nurtu tzw. Naturphilosophie – romantycznego ruchu myślowego, niezwykle popularnego w kręgach intelektualnych ówczesnych krajów niemieckich (także w państwach skandynawskich). (shrink)

It is argued that the assignment of truth values to future contingents is threatened not by a tensed metaphysics but by a temporally “local” notion of truth, i.e., by the assumption that whatever is true at a given time needs to be grounded in what exists at that time. If this assumption is accepted, tensed and tenseless metaphysics are equally vulnerable; if it is rejected, both can accommodate true future contingents. This means that semantic decisions are largely independent of metaphysical (...) considerations. The work of Correia and Rosenkranz (2018) is a clear example of how the tensed metaphysics of the growing block can incorporate true future contingents. Two potential worries are discussed in the context of their work: (a) that their grounding strategy overgeneralizes and admits true counterfactual contingents; and (b) that the growing block theory lacks sufficient resources to distinguish the unique possible future course of events that is relevant for the grounding of future contingents.

Review of the book: Człowiek na granicy istnienia. Dyskusje o śmierci mózgowej i innych aspektach umierania, Grzegorz Hołub, Piotr Duchliński, Akademia Ignatianum w Krakowie, Wydawnictwo WAM, Kraków 2017.

The book analyses a variety of topics and current issues in linguistics and literary studies, focusing especially on such aspects as memory, identity and cognition. Firstly, it discusses the notion of memory and the idea of reimagining, as well as coming to terms with the past. Secondly, it studies the relationship between perception, cognition and language use. It then investigates a variety of practices of language users, language learners and translators, such as the use of borrowings from hip-hop and slang. (...) The book is intended for researchers in the fields of linguistics and literary studies, lecturers teaching undergraduate and master's students on courses in language and literature. (shrink)

This is a summary of the recent research related to the issue of future contingents. It focuses on the aspects that were largely neglected in the traditional debate, such as relativism, pragmatics of assertion, probability, epistemology, and metaphysics.

This paper comments on five problems concerning the transformation of the Polish economy with special emphasis on employee participation and trust. 1) There can be no ethical evaluation or justification of employee participation independent of the goals of the transformation. 2) In Poland this participation is affected by deep distrust towards the whole process of transformation. 3) Privatisation is the topic most often mentioned in this connection. 4) The definition of trust becomes even more crucial when the phenomenon of distrust (...) has to be explained. 5) Institutions can become the substitute of trust.

The quest for effective medicines is very old. In modern times two important tools have been developed to evaluate efficacy of drugs: superiority and non-inferiority types of clinical trials. The former tests the null hypothesis of μ (the difference between a tested drug and comparator) ≤ 0 against μ > 0; the latter tests the null hypothesis of μ ≤ - Δ against, μ > - Δ, where Δ is the clinical difference from the comparator. In a superiority trial, a (...) new drug is tested against a placebo; in a non-inferiority trial, a new drug is tested against active treatment. In this paper, arguments are presented to show that a superiority trial against a placebo is scientifically sound but ethically unacceptable, whereas a non-inferiority trial against active treatment is ethically sound but scientifically not reliable. Switching from a superiority type of trial with placebo to a non-inferiority trial with an active-control — following the latest revision of Declaration of Helsinki — is in practice switching from the violation of the uncertainty principle to uncertainty of results. Given human and financial resources, it appears an academic question as to which is more unethical: to violate patients’ rights or to produce results without scientific value. All presented considerations lead to the conclusion that the use of a superiority trial of design with an active control instead of placebo will satisfy scientific needs, expectation of patients, and the ancient quest for effective medicines. In the era of Good (Clinical, Laboratory, Manufacture) Practice, the attention of those performing clinical trials is focused on the procedure, not always on its essence. However even the excellent performance of a trial which is not worth doing is fruitless. (shrink)

We assess Cartwright's models for probabilistic causality, and in particular, her models for EPR-like experiments of quantum mechanics. We show that her models for the EPR are mathematically incorrect and physically implausible. Finally, we argue that her models are not adequate for EPR-phenomena, since they ignore modal and spatiotemporal aspects inherent in their setup.
