New conjunctionlike and disjunctionlike operations on orthomodular lattices are defined with the aid of formal Mackey decompositions of not necessarily compatible elements. Various properties of these operations are studied. It is shown that the new operations coincide with the lattice operations of join and meet on compatible elements of a lattice but they necessarily differ from the latter on all elements that are not compatible. Nevertheless, they define on an underlying set the partial order relation that coincides with the original (...) one. The new operations are in general nonassociative: if they are associative, a lattice is necessarily Boolean. However, they satisfy the Foulis-Holland-type theorem concerning associativity instead of distributivity. (shrink)

It, is shown that Birkhoff –von Neumann quantum logic (i.e., an orthomodular lattice or poset) possessing an ordering set of probability measures S can be isomorphically represented as a family of fuzzy subsets of S or, equivalently, as a family of propositional functions with arguments ranging over S and belonging to the domain of infinite-valued Łukasiewicz logic. This representation endows BvN quantum logic with a new pair of partially defined binary operations, different from the order-theoretic ones: Łukasiewicz intersection and union (...) of fuzzy sets in the first case and Łukasiewicz conjunction and disjunction in the second. Relations between old and new operations are studied and it is shown that although they coincide whenever new operations are defined, they are not identical in general. The hypothesis that quantum-logical conjunction and disjunction should be represented by Łukasiewicz operations, not by order-theoretic join and meet is formulated and some of its possible consequences are considered.

In the paper it is shown that every physically sound Birkhoff - von Neumann quantum logic, i.e., an orthomodular partially ordered set with an ordering set of probability measures can be treated as partial infini te-valued Lukasiewicz logic, which unifies two competing approaches: the many-valued, and the two-valued but non-distributive, which have co-existed in the quantum logic theory since its very beginning.

Negative probabilities were several times proposed in the literature as a way to reconcile violation of Bell-type inequalities with the premise of local realism. It is argued that instead of using negative probabilities that have no physical meaning one can use for this purpose fuzzy probabilities that have sound and unambiguous interpretation.

Bell-type inequalities on orthomodular lattices, in which conjunctions of propositions are not modeled by meets but by maps for simultaneous measurements -maps), are studied. It is shown, that the most simple of these inequalities, that involves only two propositions, is always satisfied, contrary to what happens in the case of traditional version of this inequality in which conjunctions of propositions are modeled by meets. Equivalence of various Bell-type inequalities formulated with the aid of bivariate maps on orthomodular lattices is studied. (...) Our investigations shed new light on the interpretation of various multivariate maps defined on orthomodular lattices already studied in the literature. The paper is concluded by showing the possibility of using \-maps and \-maps to represent counterfactual conjunctions and disjunctions of non-compatible propositions about quantum systems. (shrink)

One of the authors has recently propounded an SR model which shows, circumventing known no-go theorems, that an objective interpretation of quantum mechanics is possible. We consider here compound physical systems and show why the proofs of nonlocality of QM do not hold within the SR model, which is slightly simplified in this paper. We also discuss quantum measurement theory within this model, note that the objectification problem disappears since the measurement of any property simply reveals its unknown value, and (...) show that the projection postulate can be considered as an approximate law, valid FAPP. Finally, we provide an intuitive picture that justifies some unusual features of the SR model and proves its consistency. (shrink)

In quantum computation non classical features such as superposition states and entanglement are used to solve problems in new ways, impossible on classical digital computers.We illustrate by Deutsch algorithm how a quantum computer can use superposition states to outperform any classical computer. We comment on the view of a quantum computer as a massive parallel computer and recall Amdahls law for a classical parallel computer. We argue that the view on quantum computation as a massive parallel computation disregards the presence (...) of entanglement in a general quantum computation and the non classical way in which parallel results are combined to obtain the final output.

The Geneva–Brussels approach to quantum mechanics (QM) and the semantic realism (SR) nonstandard interpretation of QM exhibit some common features and some deep conceptual differences. We discuss in this paper two elementary models provided in the two approaches as intuitive supports to general reasonings and as a proof of consistency of general assumptions, and show that Aerts’ quantum machine can be embodied into a macroscopic version of the microscopic SR model, overcoming the seeming incompatibility between the two models. This result (...) provides some hints for the construction of a unified perspective in which the two approaches can be properly placed. (shrink)

This project envisages a study of Eric Voegelin (1901-1985) and of the role played by metaxy in his vision of political philosophy. Metaxy already defined by Plato as the "in-between" matrix of the human condition is for Voegelin a powerful notion that symbolizes the intermediate state in which man experiences diverse and opposing tensions such as the ones between immanence and transcendence or mortality and immortality. The metaxy constitutes the realm of the divine-human mutual participation (methexis), and its locus resides (...) in human consciousness (nous), there where the divine reality manifests itself as the origin of being. Being the field of intermediation between opposing forces, man has to keep the balance of consciousness in order to differentiate the noetic and pneumatic dimensions and so attune his life to the divine ground of being. This project claims that for Voegelin metaxy shapes the possibility of the philosophical, historical, political and religious orientation in life. Indeed, Voegelin's approach deserves recognition as an option adequate for addressing the intellectual challenges engendered by modern and postmodern philosophies. (shrink)

Economic education is frequently blamed for negatively affecting students’ values and attitudes. Economists are reported as less cooperative, more self-interested, and more prone to free-riding. However, empirical evidence is inconclusive – certain studies support while others gainsay the so-called indoctrination hypothesis. We contribute to the discussion by running a Public Good Game quasi-experiment. Working with economics and non-economics graduates, we compared contributions to the common fund by representatives of both subsamples. Students’ contributions were then juxtaposed against the scores they achieved (...) from the exam items, testing their command of game theory to detect the supposed influence of economic teaching. We hypothesised that holders of a bachelor’s degree in economics and management would contribute less to finance the common good. We also expected that those whose exam scores were higher would donate less to the common fund in the PGG. Contrary to expectations and prior empirical evidence, students holding a bachelor’s degree in economics and management made higher contributions to the common fund than their non-economics counterparts. Also, we found no correlation between the level of donations and exam scores. We conclude that there are no grounds for considering economic teaching as promoting uncooperativeness and exerting the supposed harmful influence on students’ character. We claim that economic departments provide education rather than indoctrination. (shrink)

Author: Boruszewski Jarosław Title: MACHINES AND SYMBOLS (I) – SEMANTIC ASPECTS OF CYBERNETICS AND AUTOMATION (Maszyny i symbole (I) – semantyczne aspekty cybernetyki i automatyzacji) Source: Filo-Sofija year: 2011, vol:.12, number: 2011/1, pages: 397-425 Keywords: MACHINES, SYMBOLS, SEMANTIC, CYBERNETICS, AUTOMATION Discipline: PHILOSOPHY Language: POLISH Document type: ARTICLE Publication order reference (Primary author’s office address): E-mail: www:This article is the first part of the cycle titled “Machines and symbols”. The main issue of this cycle may be formulated as a question: can (...) machines and technical devices operate with symbols? A very important problem raised in this essay is the difference between symbols and signals. The concept of signal is also broadly discussed in the paper, because there are many different definitions of this concept. The present text contains semantic and philosophical considerations concerning cybernetics, mathematical theory of communication, industrial semiotics and semio-technics. In these theories, terms “symbol” and “signal” are often used interchangeably which leads to misconceptions. One of the most frequent misconceptions is confusing discrete signals with symbols. The author focused on communication systems where machines are senders and humans are receivers, because descriptions of these systems tend towards anthropomorphization of a machine-sender. This tendency makes signals sent out by machines treated as symbols comprehensible by a human-receiver. Another interesting aspect of machine-human communication systems is the treatment of a human-receiver as some kind of machine. Such an idea is called “mechanomorphism”. (shrink)

The subject of this abstract is the description of professional ethics of a damage adjuster in an insurance company. The work of a damage adjuster in a financial institution is more than looking after the profit of the company which goes to the company shareholders. The job is very often regarded as a position of public trust. When the aggrieved parties report a damage to an insurance company they not only entrust their personal data, which are protected by law, but (...) they also reveal confidential information like medical records, their income and important personal documentation. Reporting a damage, the aggrieved party has to be sure that the entrusted information will be only used for the purpose of the liquidation of damages. On the other hand, the damage adjuster is supposed to know that when contacting the aggrieved party, who is not an expert in insurance, should never use the professional knowledge to make decisions which are not in favour of the party. In this case the damage adjuster has two roles; not only is he a professional who is responsible for the liquidation of the damage but he is also a representative of a financial institution to the aggrieved party. Therefore there are also some marketing aspects involved in the process because quick and accurate handling of the liquidation process can convince the aggrieved party to choose the insurance company’s offer. In my paper I am going to focus on ethical issues of the profession of a damage adjuster both when interacting with clients and decision taking. I will try to show what ethical and moral standards a person working as a damage adjuster should follow. These being especially important for the profession of a personal damage adjuster. The role of a damage adjuster is not only the liquidation of the damage following procedures but also help and support for the aggrieved party by explaining the procedures, existing rights and claims.

Tematem artykułu jest filozofia miłości rozwijana przez dwóch wybitnych fenomenologów wymienionych w tytule: Dietricha von Hildebranda i Karola Wojtyłę. Obydwaj korzystali w swoich badaniach z metody fenomenologicznej; celem artykułu jest pokazanie, że w obydwu wypadkach metoda ta prowadziła do podobnych rezultatów. Autor czyni to w trzech krokach. Po pierwsze, pokazuje, że miłość pojętą w sensie ogólnym obydwaj autorzy rozumieją jako odpowiedź na wartość osoby. W Lubelskiej Szkole Personalizmu zasada miłości została wyrażona w formule: persona est affirmanda propter seipsam, a treścią (...) afirmacji, która jest należna osobie, jest miłość. W kategoriach von Hildebranda zasada ta wyrażona jest w sposób następujący: dobro osoby afirmowane jest poprzez obiektywne dobra dla osoby, które stanowią właściwą treść miłości. Po drugie, obydwaj autorzy wiele uwagi poświęcają tej specyficznej formie miłości, jaką jest miłość małżeńska. Podczas gdy mińość w sensie ogólnym stanowi odpowiedź na wyjątkową wartość osoby w stosunku do świata pozaosobowego, to miłość małżeńska jest odpowiedzią na wyjątkową wartość jednej osoby pośród wszystkich innych osób doświadczaną przez osobę płci przeciwnej. W tym sensie miłość małżeńska jest również specyficzną odpowiedzią na wartość. Po trzecie, doświadczenie miłości małżeńskiej pokazuje, że nie istnieje sprzeczność między wolnością a wzajemną przynależnością, co von Hildebrand wyraził w pojciu intentio unionis. (shrink)

Khoryev regards Petersburg, a collection of essays by Jarosław Iwaszkiewicz, published in 1976, as a windup of the writer’s complex ties with Russian culture and literature, which he was widely known to have loved and known in depth. It is a book where, through the legendary city on the river Neva, Iwaszkiewicz takes a look at a number of essential issues of Russian history and its ties with the history of Poland and the Polish people. Iwaszkiewicz avoids unequivocal judgments, noticing (...) the antinomian nature of St. Petersburg, seen as a being full of contrast but at the same time the center of revolutions and despotism, a manifestation of imperial power and the highest achievements of sophisticated art. These contrasts reveal, in Khoryev’s opinion, the multi-faceted and fullest picture of St. Petersburg and its individuality: so mysterious, overpowering and unique. (shrink)

ABSTRACTThe purpose of my paper is to determine the consequences of including an education for forgiveness in the context of developing prudence. I aim to answer two questions: what is prudent forgiveness; what constitutes education for prudent forgiveness? I present my analyses in six parts. After introduction, I point to the advantages and doubts concerning forgiveness. Then, I present prudence as a basic virtue guiding human actions. I draw mainly on the approach proposed by Thomas Aquinas, who argued that prudence (...) refers to the perfection of the command. The fourth part addresses the question of the mechanisms of prudent forgiveness. I note that a decision to forgive cannot be made in haste; that it is a decision concerning some good that the victim wants to attain in the future; finally, that forgiveness is prudent in its achievement. In the last part, I transfer prior analyses to the pedagogical level. (shrink)

W projekcie badawczym, który w zamyśle będzie składał się z dwóch merytorycznie i logicznie powiązanych artykułów, formułujemy taki schemat pojęciowy, w którym adekwatna staje się charakterystyka struktur fraktalnych w kategoriach filozoficznej koncepcji emergencji. W pracy pierwszej przedstawiamy główne idee filozofii emergencji oraz dokonujemy prób uchwycenia w procesie generowania fraktali jednostek emergentnych. Pozostajemy jednak w obrębie klasycznego rozumienia badanej relacji. W pracy drugiej, na podstawie zademonstrowanych słabości ujęć klasycznych, jako niewystarczających w specyficznym kontekście badanych struktur matematycznych, pokazujemy, że dyskurs nad emergencją (...) w matematyce staje się sensowny i uprawniony w ugruntowanym w filozofii nauk formalnych quasi-empirycznym podejściu do niektórych zagadnień w matematyce.

Celem, jaki stawiamy sobie w drugiej części naszego filozoficznego dyptychu, jest próba podjęcia dyskusji nad usytuowaniem refleksji o charakterze metaprzedmiotowym dotyczącej struktur fraktalnych w klasycznej problematyce filozofii matematyki. Pokażemy, że struktury fraktalne prowadzą do istotnego poszerzenia wskazanej problematyki poza tradycyjne ramy wyznaczane przez pytania o naturę obiektów matematycznych (ontologia matematyki) czy status wiedzy matematycznej ( epistemologia matematyczna). Interesują nas specjalnie dwie kwestie: (1) czy, i w jakim sensie, proces generowania struktur fraktalnych świadczy o quasi-empirycznym charakterze tzw. nowej matematyki; (2) czy (...) rozwijana w filozofii koncepcja emergencji nadaje się jako narzędzie badawcze do charakterystyki własności wspomnianych struktur.

This volume raises provocative questions about the status of words and literature in contemporary culture. It argues that words and images are equal and that the vast number of text messages, e-mails, tweets, comments, blogs, and daily social network posts confirms textuality's central role in new media. This is especially true of writing, as old and new forms mix online and off, reconfiguring so prolifically that no single theory can explain it, let alone project its future. This volume explores multiple (...) questions in depth: are microblogs a new literary genre? What happens when Japanese haiku crosses cultures? Is writing still an act of individuality or has it become a modern technological innovation? (shrink)

The direct reference point for these analyses is the process of making moral decisions, but a particular point of interest is the difficulty associated with making decisions when acting subjects are aware that their choice of moral good can lead to the breakdown of relationships with those close to them or to their exclusion from the group that have been most important to them so far in their lives, consequently causing them to experience loneliness. This difficulty is a challenge for (...) education, which in supporting the moral development of a maturing person should prepare her/him for choosing moral good even if this requires personal sacrifices. In these analyses, assuming that knowledge of moral good is not sufficient for morally good actions, I refer mainly to the virtues of character that facilitate making morally good decisions and I seek the answer to the question: what character traits should be shaped in maturing persons, so that as adults they can resist moral evil, even when this will clearly lead to the experience of loneliness? I propose these character traits as expressing moral virtues—especially the cardinal virtues of prudence, justice, temperance and fortitude. In this way, I join in the discussion relating to the teleology of education. I do not touch on the methodology of education, however. The argument is presented in two parts. In the first, I introduce the problem of decision-making implying consent to loneliness. In the second, I reflect on the characteristics of a person who is capable of making such a decision.
