It is true in the Cohen, Solovay-random, dominaning, and Sacks generic extension, that every countable ordinal-definable set of reals belongs to the ground universe. It is true in the Solovay collapse model that every non-empty OD countable set of sets of reals consists of \ elements.

Answer set programming (ASP) is a form of declarative programming oriented towards difficult search problems. As an outgrowth of research on the use of nonmonotonic reasoning in knowledge representation, it is particularly useful in knowledge-intensive applications. ASP programs consist of rules that look like Prolog rules, but the computational mechanisms used in ASP are different: they are based on the ideas that have led to the creation of fast satisfiability solvers for propositional logic.

The logic of single-conclusion proofs () is introduced. It combines the verification property of proofs with the single valuedness of proof predicate and describes the operations on proofs induced by modus ponens rule and proof checking. It is proved that is decidable, sound and complete with respect to arithmetical proof interpretations based on single-valued proof predicates. The application to arithmetical inference rules specification and -admissibility testing is considered. We show that the provability in gives the complete admissibility test for the (...) rules which can be specified by schemes in -language. The test is supplied with the ground proof extraction algorithm which eliminates the admissible rules from a -proof by utilizing the information from the corresponding -proofs. (shrink)

Our investigation is concerned with the finite model property with respect to admissible rules. We establish general sufficient conditions for absence of fmp w. r. t. admissibility which are applicable to modal logics containing K4: Theorem 3.1 says that no logic λ containing K4 with the co-cover property and of width > 2 has fmp w. r. t. admissibility. Surprisingly many, if not to say all, important modal logics of width > 2 are within the scope of this theorem–K4 itself, (...) S4, GL, K4.1, K4.2, S4.1, S4.2, GL.2, etc. Thus the situation is completely opposite to the case of the ordinary fmp–the absolute majority of important logics have fmp, but not with respect to admissibility. As regards logics of width ≤ 2, there exists a zone for fmp w. r. t. admissibility. It is shown that all modal logics A of width ≤ 2 extending S4 which are not sub-logics of three special tabular logics have fmp w.r.t. admissibility. (shrink)

This report of the roundtable that took place on 25 November 2021 at The Peoples’ Friendship University of Russia attempts to explain the obvious growth of interest in Neo-Kantian philosophy in general and the philosophy of the head of the Marburg School of Neo-Kantianism, Hermann Cohen, in particular. In their contributions, the participants in the discussion demonstrated that the current interest in Neo-Kantianism does not solely or even largely have to do with the history of philosophy but rather with the (...) relevance of many of the ideas of Marburg Neo-Kantianism for the modern theory of cognition, the philosophy of culture, ethics and the philosophy of religion. The course of the discussion highlighted the relevance of Cohen’s theory of cognition based on logic and rationality. The main outcome of the discussion was the conviction that the potential of many of Cohen’s ideas has yet to be fully tapped and there are grounds for considering them to be heralds of a new philosophy which, in many of its features, is only maturing.

This is a review of some of the definitions of the concept of a stable model that have been proposed in the literature. These definitions are equivalent to each other, at least when applied to traditional Prologstyle programs, but there are reasons why each of them is valuable and interesting. A new characterization of stable models can suggest an alternative picture of the intuitive meaning of logic programs; or it can lead to new algorithms for generating stable models; or it (...) can work better than others when we turn to generalizations of the traditional syntax that are important from the perspective of answer set programming; or it can be more convenient for use in proofs; or it can be interesting simply because it demonstrates a relationship between seemingly unrelated ideas.

This paper argues that extant signalling-based analyses cannot explain a range of cases of biological (and psychological) deception, such as those in which the deceiver does not send a signal at all, but that Artiga and Paternotte’s (Philos Stud 175:579–600, 2018) functional and my (Krstić in The analysis of self-deception: rehabilitating the traditionalist account. PhD Dissertation, University of Auckland, 2018: §3; Krstić and Saville in Australas J Philos 97:830–835, 2019) manipulativist analyses can. Therefore, the latter views should be given preference. (...) And because we still do not have a satisfactory definition of manipulation, the functional analysis, according to which a state is deceptive iff its function is to mislead and it misleads, is currently our best theory of deception. This is not to argue that the signalling-based analyses have no value but only that they should not be used in general analyses of biological deception. We need to move on to some other interesting issues. (shrink)

The book by Max Tegmark draws attention to the dangers and benefits that await humanity as a result of the Artificial Intelligence (AI) technologies development. Cosmologist and astrophysicist Tegmark, realizing the impossibility to predict the AI development, offers exciting scenarios of civilization development options for tens, thousands, millions and billions of years. The analysis of the opposite scenarios is aimed at the idea formation that the consequences of creating a general AI, superior to the human level, will be more significant (...) than from all other achievements of civilization. Tegmark is one of the founders and leaders of the “Beneficial AGI” movement, he presents the results of the discussion of the issues he raises with leading experts in the field of AI. Tegmark concludes his book with a call to optimism: “My book urge you to think about what future you would like, and not what future scares you, this way we can find goals for which it’s worth working”.

When we engage with fictions, we are, in effect, pretending to deal with reports of actual events. After all, numerous fictional works are explicitly designed to facilitate this kind of pretense. This was the prevailing understanding of fiction in both analytic philosophy and classical narratology for decades. However, there is a significant problem with this view: many fictional narratives routinely portray scenarios that could not possibly be the subject of anyone’s reporting. Currie’s 'mindless fictions' are one such example. This issue (...) can be referred to as the problem of unreportability. The standard solution to this challenge has been to argue that fictions are not pretend reports, but rather direct authorial stipulations to imagine specific scenarios. This paper contends, however, that such an explanation fails to provide a satisfactory account of fiction. By drawing on Walton’s notion of ‘silly questions’, it instead argues for a revised version of the report model-one that doesn’t necessarily depend on ubiquitous fictional reporters. (shrink)

Key premises of the target article by Juslin & Vll (J&V) are challenged. It is also shown that most of the six proposed by the authors as underlying the induction of emotion by music involve nonmusical proximal causes. As a replacement for the state of being-moved is proposed.

In the opening lines of this article it is claimed that history is a discipline taking role as part of unique body of science. The concept of scientific rationality is presented as the criterion of demarcation between science and pseudoscience. From this statement as a starting point, it follows that the methodological grounds for scientific predictions are common for all scientific disciplines. Different aspects of scientific predicting are critically examined: thesis of symmetry, determinism and predictability, indeterminism and predictability, reflexivity of (...) predictions, prediction of novelty and progress, predictions in relation to the time of their uttering, the prediction sketch, truthfulness and regularity in implying prediction, and predictability of human actions. In the concluding section, the author admits of the possibility of constructing the theory of history, opposed to eschatological philosophy of history, as a predictive theory with a scientific basis and a theory whose specifications limit its misuse in practice.

Estamos acostumbrados a hablar del fascismo y sus variantes contemporáneas como «enemigos de la cultura», como una fuerza política animada por el desprecio hacia las artes. Sin embargo, es evidente la extrema importancia que el fascismo concede al ámbito de la cultura; sus batallas culturales son procesos constitutivos centrales de sus luchas. Creo que pasaremos por alto dimensiones fundamentales del fenómeno fascista si no lo entendemos como una batalla por la formación de la sensibilidad social, por el cultivo de los (...) afectos y por la producción del horizonte sensible de la política. El orden sensible es el fundamento de la imaginación social, de sus límites y formas, y el control de la imaginación y la sensibilidad es el fundamento de todo poder. En la medida en que es consciente de ello, el fascismo es un proyecto estético, una reconstrucción de la sensibilidad que define los límites de lo visible y lo perceptible dentro del orden social. Lo que propongo aquí es comprender la dinámica de la actualización de tal revolución cultural fascista, teniendo en cuenta el estadio actual de los procesos materiales de reproducción cultural en las sociedades capitalistas.

El siguiente artículo aborda la crítica que manifiesta que John Stuart Mill incurrió en la falacia naturalista y en la falacia de composición. Esta temática se puede abordar de dos formas: una consistiría en analizar si Mill realmente desconoce la distinción entre lo deseado y lo deseable; otra sobre si su concepción de hedonismo, felicidad, conlleva la comisión de las falacias mencionadas. Esta última forma es el tema principal que se aborda; en otras palabras, se mencionará brevemente lo relativo a (...) si Mill confunde deseado/deseable, es/debe, y se puntualiza en cómo el hedonismo y la idea de felicidad millianos no llevan a caer en la falacia naturalista ni en la falacia de composición. En todo esto la educación jugará un papel valioso. (shrink)

The article draws a conceptual distinction the (French) structuralism of the 50’s–60’s and the post-structuralism of the 70’s, which are discussed as overlapping in their intellectual paths; their mutual dynamics is defined as a reaction of the intelligence to the pressure of depersonalized unified schemes within the logic of structuralism against free improvisation and loose interpretation instead of total explanations in the post-structuralism interpretation. The article establishes a conceptual identity of the paradoxical nature between post-structuralism (and deconstructionism, which is homogeneous (...) and identical thereto in a number of aspects), on the one hand, and constructionism with its specific process of language dismantling – social/ideological languages, social group dialects, on the other hand, which naturally leads the authors to the analysis of the paradoxicality principles, defined by post-structuralism (five principles of paradoxicality of Gilles Deleuze – paradox of regress, paradox of sterile reiteration, paradox of neutrality, paradox of absurd, paradox of Levi-Strauss); poststructuralists’ paralogisms are examined through paradoxical denotation; the late Roland Barthes’ phenomenon of paradoxicality, becoming a plot-forming principle of narration, is analyzed. Poststructuralism is conceptualized in the article as the first decisive step of post-modernism; the affinity of post-structuralist and postmodernist commitment to parody, game and irony is stated; the theory of language games in post-modern interpretation is explored; one of those games – a game of carnival – is explored within the diachronic retrospective; the affinity of parody and carnival tradition of post-structuralism and post-modernism to the romantic irony of the XIXth century and its inconsistency with the popular culture of laugh is established. The genesis of poststructuralism and post-modernism is connected with the ideological restart of the Western society before the “very end” of the Resistance ideas and the disappointment of the left European intellectuals in the “great legends” and illusions of Marxism. The blurred concepts of relativism are connected with the mutual disproportion of different layers of historical experience. (shrink)

This paper argues that there is only one proof for God’s existence in Avicenna, and only one way for establishing the proof within his metaphysical system. This metaphysical proof is essentially derived from a priori notions, among which the notion of existence has the central role. Avicenna’s proof is structured in such a way that all its concepts are either derived from the meaning of ‘existence’ or are connected with this meaning. In this sense Avicenna’s proof sets out a scenario (...) of discursive a priori knowledge established purely on considerations of fundamental ontological meanings such as ‘existence’, ‘existent’, ‘thing’, ‘necessary’, ‘possible’, ‘impossible’, ‘one’ and ‘cause’.

We study the problem of finding a basis for all rules admissible in the intuitionistic propositional logic IPC. The main result is Theorem 3.1 which gives a basis consisting of all rules in semi-reduced form satisfying certain specific additional requirements. Using developed technique we also find a basis for rules admissible in the logic of excluded middle law KC.

The travelling salesman problem (TSP) belongs to the class of NP-hard problems, in which an optimal solution to the problem cannot be obtained within a reasonable computational time for large-sized problems. To address TSP, we propose a hybrid algorithm, called GA-TCTIA-LBSA, in which a genetic algorithm (GA), tour construction and tour improvement algorithms (TCTIAs) and a list-based simulated annealing (LBSA) algorithm are used. The TCTIAs are introduced to generate a first population, and after that, a search is continued with the (...) GA. The problem of premature convergence of the GA to local optimum is tackled by a method called social disaster technique. Afterwards, the LBSA is applied to generate a new population based on one of two proposed operators called packing and judgement day. The proposed algorithm is implemented in the MATLAB environment, and its two variants, called GA-TCTIA-LBSA packing and GA-TCTIA-LBSA judgement day, are tested on symmetric and asymmetric instances from TSPLIB. The overall results demonstrate that the proposed GA-TCTIA-LBSAs offer promising results, particularly for small-sized instances. (shrink)

Rare copy number variants have a prominent role in the aetiology of schizophrenia and other neuropsychiatric disorders. Substantial risk for schizophrenia is conferred by large CNVs at several loci, including microdeletions at 1q21.1, 3q29, 15q13.3 and 22q11.2 and microduplication at 16p11.2. However, these CNVs collectively account for a small fraction of cases, and the relevant genes and neurobiological mechanisms are not well understood. Here we performed a large two-stage genome-wide scan of rare CNVs and report the significant association of copy (...) number gains at chromosome 7q36.3 with schizophrenia. Microduplications with variable breakpoints occurred within a 362-kilobase region and were detected in 29 of 8,290 patients versus 2 of 7,431 controls in the combined sample. All duplications overlapped or were located within 89 kilobases upstream of the vasoactive intestinal peptide receptor gene VIPR2. VIPR2 transcription and cyclic-AMP signalling were significantly increased in cultured lymphocytes from patients with microduplications of 7q36.3. These findings implicate altered vasoactive intestinal peptide signalling in the pathogenesis of schizophrenia and indicate the VPAC2 receptor as a potential target for the development of new antipsychotic drugs. © 2011 Macmillan Publishers Limited.

In some systems of Legniewskian Ontology were introduced as a toolkit for Husserl's and Meinong's theory of objects. Here such consi- deration is extended to Brentano-Husserl's theory of time. So-called antidiodo- rean logics are used as the foundations of the approach undertaken.

Although the concept of “pure knowledge” is one of the most interesting and singular concepts in the philosophical work of Vasily Seseman, it can only be presented after a comprehensive analysis of the philosopher’s numerous works devoted to ontological, epistemological and logical problems. Seseman believes that the main philosophical trends at the beginning of the twentieth century, namely neo-Kantianism, intuitionism and phenomenology, could not present this concept, although they did try. According to the philosopher, the main reason for the inability (...) of neo-Kantianism, intuitionism and phenomenology to start talking about pure knowledge is their inability to assert the essential difference between objective and non-objective knowledge. Sesemann pays special attention when substantiating his concept of “pure knowledge” to the difference between his approach and that of the founder of modern phenomenology. The philosopher points out that even Husserl, who concentrated attention on the specifics of inner experience, puts this specific, in the end, in dependence on the process of cognition and reflection, completely ignoring its ontological foundations. While pure knowledge, according to Seseman, is neither non-objective, nor objective knowledge, nor non-objective, nor objective being, it, in fact, is non-knowledge and non-being. It is precisely this understanding by the philosopher of this phenomenon that allows him to characterize pure knowledge as premiseless and limitless and, in general, as free from any ontological or epistemological determinations. However, on the other hand, Sesemann insists that the phenomenon of pure knowledge has the meaning of not just a regulatory idea, an infinitely distant ideal, but also a real constitutive meaning, as a principle that reveals and determines the human striving for knowledge as an interconnected and necessary process that ascends from the onto-gnoseological stage of non-objective knowledge to the epistemological, and then the logical stage of objective knowledge.

The article discusses the attitude of Georg Lukács and his adherents who formed a circle “Techeniye” toward the phenomenon of Stalinism. Despite the political nature of the topic, the authors are aspired to provide an unbiased research. G. Lukács’ views on the theory and practice of Stalinism evolved over time. In the 1920s Lukács welcomes the idea of creation of socialism in one country and abandons the former revolutionary ideas expressed in his bookHistory and Class Consciousness. This turn is grounded (...) by new interpretation of Hegel as “realistic” thinker whose “realism” was shown in the aspiration to find “reconciliation” with reality and in denial of any utopias. The philosophical evolution leading to “realism” assumes integration of revolutionaries into the hierarchy of existing society. The article “Hölderlin’s Hyperion” represents attempt to justify Stalinism as a necessary and “progressive” phase of revolutionary development of the proletariat. Nevertheless, events of the second half of the 1930s force Lukács to realize the catastrophic nature of political strategy of Stalinism. In his works, Lukács ceases to analyze political topics and concentrates on problems of aesthetics and literary criticism. However, his aesthetic position allows to reconstruct the changed political views and to understand why he had earned the reputation of the “internal opponent” to Stalinism. After 1956, Lukács turns to political criticism of Stalinism, which nevertheless remains unilateral. He sees in Stalinism a kind of the left sectarianism, the theory and practice of the implementation of civil war measures in the era of peaceful co-existence of two systems. (shrink)

Respecting and protecting the confidentiality of data and the privacy of individuals regarding the information that they have given as participants in a research project is a cornerstone of complying with accepted research standards. However, in longitudinal studies, establishing and maintaining privacy is often challenging because of the necessity of repeated contact with participants. A novel internet-based solution is introduced here, which maintains privacy while at the same time ensures linkage of data to individual participants in a repeated measures design. (...) With the use of the anonymous repeated measurements via email (ARME) procedure, two separate one-way communication systems are established through ad hoc email accounts and a secure study website. Strengths and limitations of the approach are discussed. (shrink)

It is shown that, in some non-QCD theories, there are effects shared by QCD: (i) in SU(2) Yang–Mills theory containing a nonlinear spinor field, there is a mass gap; (ii) in SU(3) Proca–Higgs theory, there are flux tube solutions with a longitudinal electric field required for producing a force binding quarks; (iii) in non-Abelian Proca–Higgs theories, there exist flux tube solutions with a momentum directed along the tube axis and particlelike solutions with a nonvanishing total angular momentum created by crossed (...) color electric and magnetic fields; in QCD, such configurations may contribute to the proton spin. We discuss the conjecture that such non-QCD theories might be a consequence of approximate solution of an infinite set of Dyson–Schwinger equations describing the procedure of nonperturbative quantization. The phenomenon of dimensional transmutation for nonperturbative quantization and the analogy between nonperturbative quantization and turbulence modeling are also discussed. (shrink)

The aim of this paper is to examine how Adorno's aesthetic and musicological thinking was received in Czech and Slovak musicology in the decades between the 60s and the 80s. The focus is on the Czech and Slovak translation of some of Adorno’s musicological treatises and lectures – especially those concerning his views on the Second Vienna School and the musical poetics of its immediate successors – which were published in former Czechoslovakia. The study offers an interesting perspective on Adorno’s (...) relatively unknown lecture Form der neuen Musik and its related, although not identical, Czech version Formové princípy súčasnej hudby [Formal Principles of Contemporary Music] as well as on his discussion with some Slovak composers and musicologists published as Dnes je možné iba radikálne kritické myslenie [Today, Only Radical Critical Thinking is Possible]. The study also considers other scientific texts by Adorno in relation to the above-mentioned translations of his works. The analysis, reflection, and interpretation of Adorno’s works in former Czechoslovakia, as well as their contemporary reception, turn out to be sporadic in the examined period. The purpose of this research is to revive awareness of their significance and to give a new impulse to their reassessment within the current musicological and philosophical reflection. (shrink)
