Artykuł prezentuje sposoby pozyskiwania klienta i działania na rzecz jego utrzymania przy pomocy nowych technologii i nowych mediów. Wykazano, iż zarządzanie relacjami z klientem jest pojęciem obszernym ze względu na różnorodność sytuacji, w których kontaktuje się on z przedsiębiorstwem. Zaprezentowano, iż zmiany technologiczne, a zwłaszcza dokonujące się w dynamicznym tempie umasowienie Internetu, przeobrażają oblicza firm i standardy obsługi klienta w stopniu niespotykanym we wcześniejszych pokoleniach. Przedstawiono również, że utrzymanie klienta jest ważniejsze niż pozyskanie nowego – zgodnie z zasadą V. Pareto. (...) Artykuł składa się z czterech rozdziałów. Pierwszy z nich opisuje rozwój metod komunikacji z klientem, które otworzyły się przed przedsiębiorstwami w związku z rozwojem Internetu. Drugi stanowi przegląd metod działań marketingowych polepszających statystyki pozyskiwania i utrzymywania klientów. W trzecim rozdziale opisano strategię zarządzania relacjami z klientami oraz scharakteryzowano typową budowę systemu informatycznego, wspomagającego realizację tejże strategii. Czwarty rozdział stanowi próbę uzasadnienia celowości nakładów ponoszonych na utrzymanie klientów. (shrink)

An erotetic calculus for a given logic constitutes a sequent-style proof-theoretical formalization of the logic grounded in Inferential Erotetic Logic ). In this paper, a new erotetic calculus for Classical Propositional Logic ), dual with respect to the existing ones, is given. We modify the calculus to obtain complete proof systems for the propositional part of paraconsistent logic CLuN and its extensions CLuNs and mbC. The method is based on dual resolution. Moreover, the resolution rule is non-clausal. According to the (...) authors knowledge, this is the first account of resolution for mbC. Last but not least, as the method is grounded in IEL, it constitutes an important tool for the so-called question-processing. (shrink)

Assume that there is no quasi-measurable cardinal not greater than 2ω. We show that for a c. c. c. σ -ideal [MATHEMATICAL DOUBLE-STRUCK CAPITAL I] with a Borel base of subsets of an uncountable Polish space, if [MATHEMATICAL SCRIPT CAPITAL A] is a point-finite family of subsets from [MATHEMATICAL DOUBLE-STRUCK CAPITAL I], then there is a subfamily of [MATHEMATICAL SCRIPT CAPITAL A] whose union is completely nonmeasurable, i.e. its intersection with every non-small Borel set does not belong to the σ (...) -field generated by Borel sets and the ideal [MATHEMATICAL DOUBLE-STRUCK CAPITAL I]. This result is a generalization of the Four Poles Theorem and a result from [3]. (shrink)

Dharmakīrti argues that there is no pramāṇa (valid means of cognition or source of knowledge) for a thesis that is a self-contradiction (svavacanavirodha). That is, self-contradictions such as ‘everything said is false’ and ‘my mother is barren’ cannot be known to be true or false. The contemporary scholar Tillemans challenges Dharmakīrti by arguing that we can know that self-contradictions are false by means of a formal logical inference. The aims of the paper are to answer Tillemans’ challenge from what we (...) take to be Dharmakīrti’s or Dharmakīrtian (someone who is like Dharmakīrti) perspective and to demonstrate the unique features of Dharmakīrti’s view of inference. By so doing, we show that the epistemology in relation to the formal conception of logic that underlies Tillemans’ challenge is problematic from Dharmakīrti’s or Dharmakīrtian perspective. The paper, thus, presents Dharmakīrti’s view of inference and logical reasoning as well as a Dharmakīrtian challenge to the formal conception of logic that is the dominant contemporary conception.

In this paper I present a novel approach to resolving a problem for inferentialist metasemantic theories that arises from a naturalistic point of view. According to normative inferentialists, expressions have their semantic content in virtue of the inferential rules that govern them. This poses a problem because a rule is a naturalistically suspicious normative notion that is used by normative inferentialists as an explanatory tool. I propose a reconciliation of naturalism and inferentialism by adopting a quasi-realist view on inferential rules. (...) According to this approach, inferential rules viewed externally are considered non-normative constitutive rules that are implicit in the dispositions of a linguistic community to allow and prohibit certain inferences. Conversely, from the internal perspective on linguistic practice, inferential rules are treated as regulative and carry a normative force, i.e., they have an action-guiding character because of the fact that they are individually accepted by members of a linguistic community.

E. T. A. Hoffmann is one of the most famous representatives of early German horror literature. He has been both, inspired by its predecessors, as well as having influenced the work of many of his successors, and hence the development of the whole genre. The present article examines a story by E. T. A. Hoffmann, “Vampirismus” from the collection of short stories “Serapions Brüder”. Emphases are, on the one hand, on the mechanisms that cause readers’ fear and uncertainty and, on (...) the other hand, the peculiarity of the vampire or Nachzehrer figure and their function in the story. Firstly, it will be shown that the vampire depicted in the work is not actually a vampire. We find here a ghoul; that is a demon from Arab culture. However, the ghoul has more to do with the monster outlined by Antoine Galland in his translation of the “One Thousand and One Nights” than with traditional folk beliefs. Secondly, the author comes to the conclusion that Hoffmann has functionalized the Horrible. This element does not work by itself, but serves the author as the background of the action. And he is using this background to let the characters reveal all their weaknesses and dark sides. The violation of the order ruling in the world as it is represented engages the reader and at the same time raises his fear. The resulting excited feelings and general alienation are further reinforced for the figure of the Nachzehrer that occurs instead of a formerly innocent, graceful girl. The emergence of the supernatural – the final confirmation of the breach of order – is responsible for the effect just described. (shrink)

The aim of the paper is to compare the role played by logical analysis in Wittgenstein’s Tractatus logico-philosophicus and Russell’s On Denoting. Whereas in Russell’s work it is an important element of his argument in support of description theory, in his pupil’s it does not function this way. Russell, while analysing various propositions, including descriptions translates them into formal language, indicating that those propositions, despite the appearances, in fact do not denote. Logical analysis shall be a tool decisive in favour (...) of Russell’s thesis. Wittgenstein similarly analyses some troublesome propositions and claims that they are meaningless. The difference is that Russell’s final conclusion is derived from logical analysis, whereas Wittgenstein’s from pure speculation. In Tractatus logico-philosophicus logical analysis is not a method thanks to which the author gets certain result, just as it was the case with his teacher and his On Denoting. In Wittgenstein’s early philosophy logical analysis concerns just a few technical problems connected only to some ideas from Principia mathematica, and not to the main subject of his work, which is the analysis of philosophical theses.

A particular kind of communication with God is the linguistic form of prayer. The theoretical analysis of each act of communication calls for a reference to the applied theory of communication. In reference to prayer it is appropriate, inasmuch as we accept the standpoint according to which the relations between God and man should be described in line with the achievements of science (A. Peacocke). Thus Peacocke describes the communication between God and man. His description is based on the assumption (...) about God\'s self-limitation to adjust to His recipient. This assumption results from the acceptance of the relay theory of communication. According to this theory, the contents of the recipients\' message (in this case God) must be reproduced by the recipient (in this case man). This theory is inappropriate to describe the acts of communication between God and man. The theory of relevancy is more appropriate for the description of this kind of relation of communication. According to this theory, it is the recipient that decides about the contents of the message. The theory does not require that self-limitation should be assumed when describing prayer as an act of communication with God. According to this theory, God, being the addressee of the acts of prayer fully understands the contents and intentions of the message. Man (the sender) may only hope that he has appropriately performed an act of communication. (shrink)

In my paper I present David Hume's philosophy from the perspective of Charles Sanders Peirce's theory of signs. I argue that by interpreting impressions and ideas as iconic signs it is possible to avoid many inconsistencies in Hume's philosophy. Apart from that it makes possible to avoid Hume's scepticism about the existence of the external world by introducing Peirce's concept of the dynamic and immediate object. What is more, the generative structure of signs helps us to deal with the "gmissing (...) shade of blue" problem. (shrink)

The liar paradox is still an open philosophical problem. Most contemporary answers to the paradox target the logical principles underlying the reasoning from the liar sentence to the paradoxical conclusion that the liar sentence is both true and false. In contrast to these answers, Buddhist epistemology offers resources to devise a distinctively epistemological approach to the liar paradox. In this paper, I mobilise these resources and argue that the liar sentence is what Buddhist epistemologists call a contradiction with one’s own (...) words. I situate my argument in the works of Dignāga and Dharmakīrti and show how Buddhist epistemology answers the paradox. (shrink)

Pluralism is widely appealed to in many areas of philosophy of science, though what is meant by ‘pluralism’ may profoundly vary. Because explanations of behaviour have been a favoured target for pluralistic theses, the sciences of behaviour offer a rich context in which to further investigate pluralism. This is what the topical collection The Biology of Behaviour: Explanatory pluralism across the life sciences is about. In the present introduction, we briefly review major strands of pluralist theses and their motivations. We (...) highlight three distinct types of pluralisms—type pluralism, fragmentation pluralism and insular pluralism—and introduce the articles of the topical collection. (shrink)

This paper’s primary purpose is to show that there is a peculiar alternative to scientism whose central thesis is not about sources of knowledge or the existence of various objects, but it aims at setting out a strategy to help decide which of the two mutually exclusive beliefs is the better one to adopt. Scientophilia, to coin a term, recommends preferring, without any discussion, a position consistent with the consensus of credible and reliable experts in a given domain. In case (...) there is no such agreement, mainly because peers disagree with each other, or experts are difficult to identify, it is recommended for a scientophile to suspend judgment. Scientophilia is not a position on science or human knowledge boundaries, but it deals with the practical side of belief change. Verdicts made by this approach are partially similar to those offered by mild scientism, as scientophilia puts scientific knowledge as one of the most reliable sources. However, it is also consistent with mild antiscientism, as in some particular cases (for example, Moorean truths), it assigns reliable expertise to non-scientific experts. Therefore it is a third way. (shrink)

The contour of a family of filters along a filter is a set-theoretic lower limit. Topologicity and regularity of convergences can be characterized with the aid of the contour operation. Contour inversion is studied, in particular, for iterated contours of sequential cascades. A related problem of continuous extension of maps between maximal elements of sequential cascades to full subcascades is solved in full generality.

The aim of the paper is to present two natural deduction systems for Intuitionistic Sentential Calculus with Identity ( ISCI ); a syntactically motivated \(\mathsf {ND}^1_{\mathsf {ISCI}}\) and a semantically motivated \(\mathsf {ND}^2_{\mathsf {ISCI}}\). The formulation of \(\mathsf {ND}^1_{\mathsf {ISCI}}\) is based on the axiomatic formulation of ISCI. Its rules cannot be straightforwardly classified as introduction or elimination rules; ISCI -specific rules are based on axioms characterizing the identity connective. The system does not enjoy the standard subformula property, but due (...) to the normalization procedure non-subformulas can label only leaves of proofs. In \(\mathsf {ND}^2_{\mathsf {ISCI}}\), we propose only two general identity-related rules, in reference to the treatment of the identity connective in First-Order Logic. (shrink)

We define Kripke semantics for propositional intuitionistic logic with Suszko’s identity. We propose sequent calculus for ISCI along with cut-elimination theorem. We sketch a constructive interpretation of Suszko’s propositional identity connective.

Our main inspiration is the work in paper (Gitik and Shelah in Isr J Math 124(1):221–242, 2001). We will prove that for a partition \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${\mathcal{A}}$$\end{document} of the real line into meager sets and for any sequence \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${\mathcal{A}_n}$$\end{document} of subsets of \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${\mathcal{A}}$$\end{document} one can find a sequence \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} (...) \setlength{\oddsidemargin}{-69pt} \begin{document}$${\mathcal{B}_n}$$\end{document} such that \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${\mathcal{B}_{n}}$$\end{document}’s are pairwise disjoint and have the same “outer measure with respect to the ideal of meager sets”. We get also generalization of this result to a class of σ-ideals posessing Suslin property. However, in that case we use additional set-theoretical assumption about non-existing of quasi-measurable cardinal below continuum. (shrink)

p-consequence (plausible consequence; see [2]) allows for a formulation of non-deductive reasonings, i.e., such where the conclusion has weaker justification then assumptions and thus when added to the set of assumptions results in its extension. But theoretical modesty of p-consequence operation does not tell the difference between “good” and “worse” conclusions. Therefore the bisconsequence is introduced.

In one of his papers, Moti Mizrahi argues that arguments from an expert opinion are weak arguments. His thesis may seem controversial due to the consensus on this topic in the field of informal logic. I argue that its controversy is framework-dependent, and if translated into a different framework, it appears to be a correct, however trivial, claim. I will use a framework based on Douglas Walton’s argumentation scheme theory and his conception of examination dialogue to demonstrate that it is (...) so. It appears that Mizrahi’s idiosyncratic framework provides an excessively restrictive conception of an argument from expert opinion than Walton’s scheme does. There is no quarrel between both frameworks, as they yield analogous, almost identical, outcomes of argument evaluation. The actual and crucial disagreement is on the topic of argument classification. Mizrahi’s conception of arguments from an expert opinion imposes exact conditions that such argument must fulfil: an expert’s opinion o truth-value must be unknown; o must be unsupported by any evidence; an expert’s peers neither accept o nor reject it. These exclude, by definition, every possible strong, in Walton’s terms, variant of such an argument. Therefore, if rephrased with the notions of the examination dialogue framework, Mizrahi’s thesis sounds as follows: weak arguments from expert opinion are weak arguments. (shrink)

Wittgenstein introduced his claim about colour incompatibility originally in the Tractatus Logico-Philosophicus , where he stated that there could be only one colour in one place and time. It is commonly believed that Wittgenstein abandoned his conception of logical atomism when he realized the consequences of this claim. The aim of this article is to provide an interpretation of the colour incompatibility claim in terms of Wittgenstein’s phenomenology. I will focus on two works of great significance for the claim: Some (...) Remarks on Logical Form and Philosophical Remarks . These two works were written between 1929 and 1930, which is the beginning of the “middle period” in Wittgenstein’s philosophy. I will focus not only on Wittgenstein’s formulation of the colour incompatibility claim, but also on how this claim was justified. The explanation of Wittgenstein’s justification of this claim will help to understand his phenomenology and theory of philosophical grammar. (shrink)

Freedom of contract and corrective justice are considered to be the basic principles governing contract law. However, many contemporary legal orders implement various policy goals into private law. The regulatory private law of the European Union is the most striking example of such a trend. This article aims at reconciling the corrective justice theory of private law and the principle of freedom of contract with the regulatory dimension of the EU law. The main argument is that the meaning of the (...) concept of harm, one that is crucial to the principle of corrective justice, should be understood broadly so that it can transform the corrective justice theory from a monistic one into a pluralistic one.

Obliczeniowa teoria umysłu wywarła znaczący wpływ na kształt współczesnej filozofii zajmującej się tym fenomenem. Dopuszczenie możliwości algorytmizacji ludzkich procesów umysłowych pociąga za sobą konsekwencje zarówno w postrzeganiu umysłu pod kątem funkcjonalnym, jak i treściowym. Generuje to również pytanie o naturę tychże procesów. Odradza się tym samym znany z tradycji filozofii kontynentalnej problem relacji ciało-umysł. Odrzucenie kartezjańskiego dualizmu doprowadziło wielu przedstawicieli kognitywnego nurtu do przeświadczenia, że źródeł naszych treści mentalnych poszukiwać należy w procesach zachodzących w mózgu. Celem artykułu jest analiza argumentów (...) adwersarzy obliczeniowej teorii, ze szczególnym uwzględnieniem ich konsekwencji dla programu wyjaśniania fenomenu umysłu w zgodzie z paradygmatem materialistycznym.

We introduce a notion of ideal type such that any two ideals with the same ideal type are isomorphic. From this we infer, under the axiom t = h, that each ideal which consists of all nowhere Ramsey sets contained in some family of infinite subsets of natural numbers is isomorphic with the ideal of all nowhere Ramsey sets.

The article aims to present issues arising out of differences in the way that the terms chimera and hybrid are defined in legal systems and by natural sciences in the context of mixing human and animal DNA. The author analyses the different approaches to defining these terms used in various legal systems, dividing them into groups in light of conclusions reached from examining definitions used in natural sciences. The distinction is used to answer the question of which approach to definitions (...) applied by legislators is the best way to handle the subject of human-animal organisms, given the need to balance their impact on medicine and the ethical concerns that arise.

The aim of the article is to describe the myth of femme fatale. Starting from popular culture and ending with the representatives of archaic cultures, the author tries to indicate the women who are described in patriarchal narratives as those who bring men to defeat and ruin. An important figure for the whole argument is Lilith, who, according to Jewish legends, was the first wife of Adam. Lilith was erased from the biblical tradition because she opposed her partner and turned (...) away from God. She has become the female archetype of sin, the symbol of sexual vampirism and the rejection of motherhood. All these features make up the femme fatale syndrome. (shrink)

Faces of liberalism: formation of a Christian liberal community in Krakow: The aim of the essay is to show the birth of the Kraków liberal community in the years 1977–1980. An attempt is made to reconstruct the main ideological assumptions of the liberal entourage in the context of the opposition activities of Robert Kaczmarek and Mirosław Dzielski. The author refers to the main events occurring in this period, such as the establishment of the Prywatna Inicjatywa Krakowska and the magazine Merkuryusz (...) Krakowski i Światowy, as well as paying special attention to the program texts that were published in it. The article also contains a reconstruction of the debate aimed at classifying the views presented by Mirosław Dzielski. (shrink)

Stereotype accuracy is a contentious topic. Part of the problem is that typically stereotypes are generic statements whose truth status is unclear due to the fact that they are ill-defined quantitatively. The article focuses on the epistemic aspect of stereotypical beliefs. In the ongoing debate, I side with those who argue against stereotypes being wrong or inaccurate by virtue of definition alone. I propose that, when possible, stereotype accuracy should be assessed in probabilistic terms by inspecting how likely a generic (...) statement is to be true when applied to individual representative of the relevant group. This approach applies equally well to investigating the actual and the perceived accuracy of stereotypes. (shrink)
