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..

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).

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.

In this paper we investigate some basic semantic and syntactic conditions characterizing the equivalence connective. In particular we define three basic classes of algebras: the class of weak equivalential algebras, the class of equivalential algebras and the class of regular equivalential algebras.Weak equivalential algebras can be used to study purely equivalential fragments of relevant logics and strict equivalential fragments of some modal logics. Equivalential algebras are suitable to study purely equivalential fragment of BCI and BCK logic. A subclass of the (...) class of regular equivalential algebras is suitable to study equivalential fragments of ukasiewicz logics. Some subvarieties of the class of regular equivalential algebras provide natural semantics for equivalential fragments of the intuitionistic prepositional logic and various intermediate logics.

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.

Let J be any proper ideal of subsets of the real line R which contains all finite subsets of R. We define an ideal J * ∣B as follows: X ∈ J * ∣B if there exists a Borel set $B \subset R \times R$ such that $X \subset B$ and for any x ∈ R we have $\{y \in R: \langle x,y\rangle \in B\} \in \mathscr{J}$ . We show that there exists a family $\mathscr{A} \subset \mathscr{J}^\ast\mid\mathscr{B}$ of power ω (...) 1 such that $\bigcup\mathscr{A} \not\in \mathscr{J}^\ast\mid\mathscr{B}$ . In the last section we investigate properties of ideals of Lebesgue measure zero sets and meager sets in Cohen extensions of models of set theory. (shrink)

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)

Der Artikel beschäftigt sich mit der Rolle, die der Fanatismus in der Philosophie und Psychologie Friedrich Nietzsches spielt. Er wirft die These auf, dass Fanatismus mit Ressentiment und Nihilismus verbunden ist und interpretiert den deutschen Denker in folgendem Sinne: Fanatismus ist der Abwehrmechanismus eines Menschen, der Ressentiment empfindet. Durch ein Einsatz dieses Abwehrmechanismus schützt sich der Mensch vor den Konsequenzen der nicht gut durchgeführten Fälschung der Werte auf den Weg seiner ressentimentalen Umwertung- d. h. vor dem Nihilismus.

An increasing number of drugs removed from the market because of unacceptable toxicity raises concerns regarding preapproval testing of drug safety. In the present paper it is postulated that the non-inferiority type of trial should be abandoned in favor of the superiority trial with active controls and less stringent (p<0.1, both for efficacy and toxicity) statistics. This approach will increase sensitivity of detection of drug-induced adverse effects at the expense of increasing false positive results regarding the difference in efficacy between (...) the tested and reference drug. Such a move will increase the protection of future patients. In addition, the proposed design is far more acceptable from the clinical (e.g. no need to specify the statistically expected “unimportant” number of deaths) and ethical points of view, as well as being favored by the strong incentive of involved parties. In the second part of this paper arguments are presented in favor of the hypothesis that placebo (still used in some superiority trials) does not induce adverse effects. The assertion that placebo may induce adverse effects is probably biased by the nature of the clinical experiment. Such a conclusion is supported by studies indicating that placebo-induced adverse effects are disease — and treatment — specific. The modification of clinical trials according to the proposed changes may increase the trials’ sensitivity at detecting adverse effects of drugs. (shrink)

Jacek Filek criticizes the modern “nonethical” ethics. He points out its break with philosophy, lack of self-criticism, inanity, undue and fruitless formalism, and academism. His article makes a general request for the restitution of ethics as the independent and dignified scholarly discipline closely connected with world and life.

We assess Cartwright's models for probabilistic causality and, in particular, her models for EPR-like experiments of quantum mechanics. Our first objection is that, contrary to econometric linear models, her quasi-linear models do not allow for the unique estimation of parameters. We next argue that although, as Cartwright proves, Reichenbach's screening-off condition has only limited validity, her generalized condition is not empirically applicable. Finally, we show that her models for the EPR are mathematically incorrect and physically implausible.

This paper is a study of similarities and differences between strong and weak quantum consequence operations determined by a given class of ortholattices. We prove that the only strong orthologics which admits the deduction theorem (the only strong orthologics with algebraic semantics, the only equivalential strong orthologics, respectively) is the classical logic.

In this article we consider linear isomorphisms over the field of rational numbers between the linear spaces ℝ2 and ℝ. We prove that if f is such an isomorphism, then the image by f of the unit disk is a strictly nonmeasurable subset of the real line, which has different properties than classical non-measurable subsets of reals. We shall also consider the question whether all images of bounded measurable subsets of the plane via a such mapping are non-measurable.

The following is an attempt to grasp synthetically the strategy and development of Jean Baudrillard’s intellectual standpoint. My view emphasizes late ideas by French Philosopher, while the earlier ones are treated from this perspective as preliminary. After having left Marxist and post-Marxist positions, Baudrillard developed an original and idiosyncratic way of thinking about contemporary world that—inspired by Nietzschean idea that the power of interpretation prevails over representation of truth—evolves around rejection of the traditional ideas of the social, reality and revolt, (...) while employing categories of mass, simulation or catastrophe. This attitude took him not only beyond good and evil, but also to affirmation of death and terror, conducting to an extreme standpoint of “intellectual terrorism”. (shrink)

The aim of this paper is to defend the ontological Principle of Sufficient Reason (PSR-O). I analyse various versions of this principle and various ways of justifying it. Then I attempt to challenge some counterexamples allegedly refuting a universal application of the PSR-O. There are standard and non-standard versions of the PSR-O. The PSR-Ostand can only be valid if there are no chains of contingent reasons and outcomes with first modules, i.e. all chains are actually infinite. However, there are serious (...) arguments against this possibility. The necessary condition of the PSR-Onon-stand is the existence of a necessary substance: that substance would be a direct reason of certain contingent states of affairs obtaining in its domain, and those states of affairs would then be indirect reasons for all other contingent states of affairs and things. There are two advantages of the PSR-Onon-stand: a nomological unity of the world and explanatory simplicity. (shrink)

We present the results of research carried out as a part of the project “Current Controversies about Human Origins: Between Anthropology and the Bible”, which focused on the supposed conflict between natural sciences and some branches of the humanities, notably philosophy and theology, with regard to human origins. One way to tackle the issue was to distribute a questionnaire among students and teachers of the relevant disciplines. Teachers of religion and the natural sciences (biology, chemistry, and physics) and students of (...) theology, philosophy, and the natural sciences (specializing in biology and/or anthropology) were asked to answer eleven questions concerning the perception of the conflict between evolutionism and creationism, the definitions of creation and evolution, the existence of a human spiritual element, and the ways of interpreting the Bible, especially the first chapters of the book of Genesis. In the paper we present and analyze selected results of this questionnaire. Among interesting findings there are the following: 1) the opinion concerning the relationship between evolutionism and creationism largely depends on the respondent’s general attitude toward religion, and not on their field of study or teaching expertise, which runs contrary to the received view attributing the opinion of the conflict between science and religion to people’s educational or professional background; 2) The conflict is far more pronounced in the group of nonbelievers. This distinguishes Poland from other countries, notably the United States, where the majority of people with strong religious beliefs seem to maintain that there is a conflict between the natural sciences and religion; 3) literal understanding of the Bible was rejected by vast majority of the respondents, including those who insist on the ‘conflict view’, which seems to make the situation in Poland again quite different from that in some other countries; 4) Unsophisticated understanding of creation positively correlates with the ‘conflicting view’ on the one hand, while, on the other, erroneous understanding of the basics of the theory of evolution appears to have its bearing on too optimistic vision of certain coherence between religion and science. We suggest some hypotheses to explain these and other results of the questionnaire. (shrink)

Author: Migasiński Jacek Title: TRANSCENDENTALISM OF LEVINAS (Transcendentalizm Levinasa) Source: Filo-Sofija year: 2006, vol:.6, number: 2006/1, pages: 21-41 Keywords: LEVINAS, KANT, TRANSCENDENTALISME, PHÉNOMÉNOLOGIE Discipline: PHILOSOPHY Language: POLISH Document type: ARTICLE Publication order reference (Primary author’s office address): E-mail: www:En s’inspirant de l’approche de Natalie Depraz qui defini la position théorique de Husserl tardif comme «l’empirisme transcendental», je propose retrouver aussi dans la philosophie de Emmanuel Levinas une forme specifique du transcendentalisme, transcendentalisme de genese – différente de l’apriorisme transcendental de (...) Kant. Je demontre que – en dépit de l’apparence – on peut interpreter certaines couches de la réalité ou certains phénoménes ou encore événements que Levinas soumet à l’analyse – telles que «il y a», «la mort», «le feminin», «la fecondité», «la jouissance» et «le travail – la demeure» – comme les conditions empirico-transcendentales de la genese du sujet mur et susceptible de nouer «l’intrigue éthique». Je montre ainsi combine Levinas doit aux méthodes classiques de la phénoménologie. Cependant je demontre aussi que ni la transcendence de l’Infini qui se devoile dans «l’épiphanie du visage», ni cette figure du sujet qui est décrite dans la dernière période de Levinas, notamment «le soi» – le sujet dechiré de l’interieur par la diachronie propre a lui, le sujet an – archique, indicible dans un langage prédicatif – ne peuvent plus remplir les functions transcendentales. En fin j’essai de demontrer que la perspective transcendentale chez Levinas trouve ses limitations et qu’elle est remplacée dans la dernière période par une sorte de dialectique apophatique.

We investigate the semantics of historical counterfactuals in indeterministic contexts. We claim that "plain" and "necessitated" counterfactuals differ in meaning. To substantiate this claim, we propose a new semantic treatment of historical counterfactuals in the Branching Time framework. We supplement our semantics with supervaluationist postsemantics, thanks to which we can explain away the intuitions which seem to talk in favor of the identification of "would" with "would necessarily".

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.

Education is increasingly coming under the shadow of economics. In this article we engage in ideology critique by applying a critical realist analysis to conventional economic models and the teaching of students. Through a historical and philosophical interrogation, we argue that the current curriculum suffers from a diminutive understanding of human being. We argue that economics education has for a long time now worked with a highly abstracted and decontextualized idea of human being that has absented other dimensions of human (...) concerns. We examine the current English Advanced level economic curriculum and the revised curriculum which will be taught from September 2015. Using an understanding of the dynamics of structure and agency and that economics operates in open systems, we argue for retroduction as an appropriate methodology. (shrink)
