This review article discusses Andrzej Bielecki’s book _Models of Neurons and Perceptrons: Selected Problems and Challenges_, as published by Springer International Publishing. This work exemplifies “philosophy in science” by adopting a broad, multidisciplinary perspective for the issues related to the simulation of neurons and neural networks, and the author has addressed many of the important philosophical assumptions that are entangled in this area of modeling. Bielecki also raises several important methodological issues about modeling. This book is recommended for any (...) philosophers who wish to learn more about the current state of neural modeling and find inspiration for a deeper philosophical reflection on the subject.

Resumen El objetivo del presente artículo es analizar en la historia del español dos tipos de fórmulas de saludo, entendidas como unidades discursivas propias del acto de habla expresivo que sirven para abrir el canal comunicativo de las relaciones sociales. A través de la búsqueda sistemática en textos del CORDE de hasta finales del siglo XIX, intentaremos hallar (i) los factores sociopragmáticos que desempeñan el papel más importante en cada tipo de saludo, (ii) el origen paradigmático de cada fórmula, (iii) (...) su distribución sociocultural y las preferencias discursivas e informativas, y (iv) su nivel de predominio en determinadas épocas.

The changes brought about in Poland and elsewhere in Europe by the fall of Communism have given rise to hopes for the establishment of a political system differing from the one which had been the fate of these countries. In place of totalitarianism, a new political system is to be created based on the democratic principles of a state under the rule of law. The transformation from totalitarianism to democracy is a process which has not yet been completed in Poland (...) and still requires many efforts to be made before this goal may be achieved. One may also enumerate various pitfalls jeopardising this process even now. The dangers cannot be avoided if their sources and nature are not identified. Attempts to pervert the law and the political system may only be counteracted by legal means if the system based on the abuse of the law has not yet succeeded in establishing itself. Resistance by means of the law only has any real chance of success provided it is directed against attempts to set up a totalitarian system. Once the powers which are hostile to the state bound by the rule of law take over the institutions of the state, such resistance is doomed to failure. (shrink)

The aim of this essay is to create a coherent theistic model of a solution to the problem of evil. To this end, it is shown that the differences in Kierkegaard’s and Plantinga’s accounts of the problem of evil can be reconciled if looked at from a broader theistic perspective. This requires, on the one hand, that Plantinga’s immanent and logical vision be extended to include Kierkegaard’s spiritual and existential view of evil, and, on the other hand, that a correction (...) be made to Kierkegaard’s view thereof, as a result of the way in which Plantinga presents the relationship between good and moral evil in the world. Consequently, in Plantinga’s Free Will Defense the existence of God is consistent with the existence of evil, not because God has a reason to permit evil in the world, but because evil as a real element of the temporal world does not come from God. In Kierkegaard’s Free Spirit Offense, in turn, the interpretative model applied demonstrates that the existence of moral good must be independent of the existence of spiritual evil, for otherwise the moral evil of immanence would not be able to be forgiven by the spiritual good of transcendence.

W kontekście wielości pojęć osoby i ich znaczenia dla sposobu organizowania przez człowieka życia jednostkowego i społecznego, sprawą kluczową jest zwrot w kierunku realistycznego pojęcia osoby. W niniejszym studium przeprowadzono krytyczną analizę kilku wybranych relacjonalnych koncepcji osoby z pozycji tomizmu egzystencjalnego. W efekcie przeprowadzonej analizy potwierdzono założoną hipotezę, iż wybrane relacjonalne koncepcje osoby mają charakter aprioryczny, jednakże tylko w odniesieniu do istoty osoby. Studium odpowiada na pytanie, dlaczego analizowane koncepcje nie wyjaśniają samej istoty realnej osoby ludzkiej, a tylko wskazują na (...) jej cechy rozpoznawcze, opisując egzystencję i drogi spełniania się osoby. In search of a realistic concept of person In the context of the multiplicity of concepts of the person and their importance for the way in which man organizes his individual and social life, a turn toward a realistic concept of the person is crucial. In this study, a critical analysis of several selected relational concepts of the person from the position of existential Thomism is carried out. As a result of the analysis, the assumed hypothesis was confirmed that the selected relational conceptions of the person are a priori, however, only with regard to the essence of the person. The study answers the question of why the analysed concepts do not explain the very essence of the real human person, but only point to its identifying features, describing the existence and ways of fulfilment of person.

M. E. Rudin proved, under CH, that for each P-point p there exists a P-point q strictly RK-greater than p. This result was proved under ${\mathfrak {p}= \mathfrak {c}}$ by A. Blass, who also showed that each RK-increasing $ \omega $ -sequence of P-points is upper bounded by a P-point, and that there is an order embedding of the real line into the class of P-points with respect to the RK-ordering. In this paper, the results cited above are proved under (...) the assumption that $\mathfrak { b}=\mathfrak {c}$. A. Blass asked in 1973 which ordinals can be embedded in the set of P-points, and pointed out that such an ordinal cannot be greater than $ \mathfrak {c}^{+}$. In this paper it is proved, under $\mathfrak {b}=\mathfrak {c}$, that for each ordinal $\alpha < \mathfrak {c}^{+}$, there is an order embedding of $ \alpha $ into P-points. It is also proved, under $\mathfrak {b}=\mathfrak {c}$, that there is an embedding of the long line into P-points. (shrink)

Artykuł dotyczy zagadnienia wolności indywidualnej i problemu zagrożeń, jakie może pociągać za sobą hołdowanie niektórym jej odmianom. Klasycznie pojmowana wolność, zwana negatywną, utożsamiana z brakiem zewnętrznego przymusu, może stać w opozycji do tak zwanej wolności pozytywnej. To ostatnie pojęcie definiowane jest na ogół poprzez możność, co przywodzi na myśl jego związek z pojęciem władzy. Punktem wyjścia rozważań stała się analiza wybranych aspektów obu wolności. Rozróżnienie tych dwóch fenomenów jest istotne dla zrozumienia niektórych procesów zachodzących we współczesnej wspólnocie politycznej. Konsekwentne odwoływanie (...) się do paradygmatu tzw. wolności pozytywnej może bowiem przynosić trudne do przewidzenia konsekwencje w postaci uzasadnianej ideologicznie ingerencji w wiele sfer ludzkiego działania. Za szczególnie brzemienne w skutki należy uważać konotacje tzw. wolności pozytywnej i równości. W istocie bowiem wolność pozytywna, a szczególnie jej postulat szerzenia równości, staje się pretekstem dla zwiększania zakresu politycznego panowania. Może to wyrażać się w dążności do urzeczywistniania aspiracji jednych grup społecznych kosztem innych. Takie podejście siłą rzeczy stoi w opozycji do poglądów upatrujących fundamentów społecznego porządku w prymacie wolności negatywnej i obowiązywaniu zasad sprawiedliwości. Wspomniana ingerencja instytucji państwa w ludzkie działanie, będąca skutkiem propagowania niektórych aspektów koncepcji „wolności do” może grozić redukcją podmiotowości moralnej osób. (shrink)

The paper refers to selected problems of exploitation in the face of justice. The analysis is based on the definitions of exploitation contained in the Polish Penal and Civil Codes. The main subject of our interest is the identification of the necessary and sufficient conditions for the recognition of exploitation as being unjust. Supplementary question will refer to a specific type of justice which should be considered in this case. In respect to this we should consider retributive, distributive and social (...) justice. Another important factor in this regard is the accepted theory of value. In the considered subject we will focus on the labour theory of value. The principal problem could be reduced to questions whether the exploitation is ipso facto unjust and how these two phenomena are related to each other. (shrink)

The main theorem says that a consequence operator is an effective part of the consequence operator for the classical prepositional calculus iff it is a consequence operator for a logic satisfying the compactness theorem, and in which every finitely axiomatizable theory is decidable.
