This article presents an empirical examination of the consequences of the virtual entailment principle proposed by Jean Buridan to resolve the Liar paradox. This principle states that every sentence in natural language implicitly asserts its own truth. Adopting this principle means that the Liar sentence is not paradoxical but false, because its content is contradictory to what is virtually implied. As a result, humans should perceive the Liar sentence the same way as any other false sentence. This solution to the (...) Liar paradox received criticism for making ad hoc claims about the natural language. However, thanks to modern advancements in psychophysiology, it became possible to empirically investigate if the human brain really perceives the Liar sentence like a false sentence. We designed and conducted an experiment to examine brain activity in response to true sentences, false sentences and self-referential sentences. Our results provide support for the Buridan’s hypothesis and show that the Liar sentence is processed by the human brain identically to false sentences, while the Truthteller sentence is perceived identically to true sentences. This agrees with predictions derived from the virtual entailment principle and supports the idea that humans think with the logic of truth—a logic for which the truth is a designated value of its adequate semantics.

The paper examines the Tattvôpaplava-siṁha of Jayarāśi Bhaṭṭa, and presents an analysis of his positive arguments that can be traced in the work. Despite the widely held opinion that Jayarāśi was a sceptic or held no positive opinions, the author concludes that, first, Jayarāśi does not fit a standard description of a sceptic. What may appear as an approach to philosophical problems, typical of a sceptic, turns out to be Jayarāśi’s particular method of critical examination on the part of a (...) rationalist. Second, a number of positive views Jayarāśi entertains can be identified in his work, and most of them overlap with much of the doctrine of the Cārvākas and Lokāyatas and materialist tradition recorded as early as the Sāmañña-phala-sutta. Therefore, Jayarāśi should be classified as a representative of the Cārvāka/Lokāyata tradition. (shrink)

The paper presents an analysis of the anumāna chapter of Jayarāśi’s Tattvôpaplava-siṁha and the nature of his criticism levelled against the anumāna model. The results of the analysis force us to revise our understanding of Jayarāśi Bhaṭṭa as a sceptic. Instead, he emerges as a highly critical philosopher. In addition, the nature of Jayarāśi’s criticism of the anumāna model allow us to conclude that anumāna should not be equated with inference, but rather is its limited subset, and may at best (...) be rendered as ‘disputational inference’, ‘debational inference’ or even ‘dialogical inference’. Jayarāśi applies a range of logical laws which clearly represent patterns of what can be classified as a priori reasoning and analytical justifications for knowledge, which were traditionally not reckoned sound. Against the backdrop of Jayarāśi’s criticism of anumāna, the paper also attempts to provide an explanation to why Indian philosophy and logic did not develop any concept of proper symbols and variables.

How should ethical standards be maintained within engineering and engineering education? The present paper addresses this question with relation to the dominant models of engineering ethics (EE) to show that their limits might be overcome by incorporating the vocabulary of neo-Aristotelian virtue ethics. On the basis of the MacIntyrean concept of practice, the secondary role of engineering is highlighted which echoes similar debates concerning education. This similarity is picked up to argue that the role of the engineer in relation to (...) the end-users of their projects should be understood as on a par with the teacher-student relationship. This enables us not only to redefine the internal good of engineering and the ground for EE, but also to indicate the key virtues and educational models for engineering that they should be key parts of.

In the discussions concerning the date of Dharmakīrti, Jaina sources have never been seriously taken into account. They may, however, provide a valuable insight because Dharmakīrti both criticised and was criticised by Jaina thinkers. Two Jaina authors, Samantabhadra and Pūjyapāda Devanandin, may prove crucial in determining the actual dates of Dharmakīrti. The paper argues that Dharmakīrti directly influenced Samantabhadra in a number of ways, which sets the terminus ante quem for Dharmakīrti, and his traditional chronology has to be reconsidered in (...) the light of new findings. The paper suggests new dates for all the three authors. (shrink)

OBJECTIVE PREDICATION The author claims that there are two kinds of predicates that are used to describe cognitive states of mind like beliefs or perception. Using some of them, one can describe the cognitive states of mind directly, whereas using some others, one can describe these states in comparison with one’s own. For example, one can say that a person has a belief or one can say that that person’s belief is according to his own beliefs. In the latter situation, (...) he uses the predicate “to know”. The conditions that Peter uses correctly the sentence “John knows that p” are as follows: (1) Peter believes that John believes that p; (2) Peter believes that p; (3) Peter believes that the reasons for which John believes that p have a good justification. In a similar way one can ascribe to somebody a visual impression of an object x or to compare that person’s impressions with his own cognitive states. In the latter situation one uses the predicate “to see” (to perceive). The conditions that Peter uses correctly the sentence “John can see x” are the following: (I) Peter believes that John has visual impression of object x; (II) Peter believes that object x exists; (III) Peter believes that this that John has visual impression of object x is according to the laws of vision. When one uses predicates that describe cognitive states of mind of a person (possession of beliefs or sensory impressions), one speaks subjectively, whereas when one speaks objectively, he uses predicates that allow him to compare cognitive states of mind of a person with his own. Keywords: PREDICATION, BELIEFS, PERCEPTION. (shrink)

We examine Paul Halmos’ comments on category theory, Dedekind cuts, devil worship, logic, and Robinson’s infinitesimals. Halmos’ scepticism about category theory derives from his philosophical position of naive set-theoretic realism. In the words of an MAA biography, Halmos thought that mathematics is “certainty” and “architecture” yet 20th century logic teaches us is that mathematics is full of uncertainty or more precisely incompleteness. If the term architecture meant to imply that mathematics is one great solid castle, then modern logic tends to (...) teach us the opposite lesson, namely that the castle is floating in midair. Halmos’ realism tends to color his judgment of purely scientific aspects of logic and the way it is practiced and applied. He often expressed distaste for nonstandard models, and made a sustained effort to eliminate first-order logic, the logicians’ concept of interpretation, and the syntactic vs semantic distinction. He felt that these were vague, and sought to replace them all by his polyadic algebra. Halmos claimed that Robinson’s framework is “unnecessary” but Henson and Keisler argue that Robinson’s framework allows one to dig deeper into set-theoretic resources than is common in Archimedean mathematics. This can potentially prove theorems not accessible by standard methods, undermining Halmos’ criticisms. (shrink)

The paper first proposes a new definition of religion which features a novel four-layered element and which does not involve any circularity ; thereby, it allows to clearly distinguish the phenomenon of religion from certain other worldviews, in particular from certain political ideologies. Relying on the findings, the paper develops two structural conceptual models which serve to describe religious and non-religious belief systems. Further, the definition and the conceptual models allow to establish a clear criterion to distinguish pivotal structural differences (...) between religious and non-religious belief systems. The criterion is based on the concept of two kinds of rationality: first-level and second-level rationalities. These will demonstrate to what degree religion can be a rational enterprise, and what role logic can play in it. The result is a clear-cut line in the structures of religious and certain consistent non-religious belief systems. (shrink)

In his 1887's Mitteilungen zur Lehre von Transfiniten, Cantor seeks to prove inconsistency of infinitesimals. We provide a detailed analysis of his argument from both historical and mathematical perspective. We show that while his historical analysis are questionable, the mathematical part of the argument is false.

In the paper, several data reduction techniques for machine learning from big datasets are discussed and evaluated. The discussed approach focuses on combining several techniques including stacking, rotation, and data reduction aimed at improving the performance of the machine classification. Stacking is seen as the technique allowing to take advantage of the multiple classification models. The rotation-based techniques are used to increase the heterogeneity of the stacking ensembles. Data reduction makes it possible to classify instances belonging to big datasets. We (...) propose to use an agent-based population learning algorithm for data reduction in the feature and instance dimensions. For diversification of the classifier ensembles within the rotation also, alternatively, principal component analysis and independent component analysis are used. The research question addressed in the paper is formulated as follows: does the performance of a classifier using the reduced dataset be improved by integrating the data reduction mechanism with the rotation-based technique and the stacking?

The paper presents the possibility of using the lifestyle concept for better recognition of the employee motivation attitude towards work leadership and managerial behaviours. That could result in better human capital management in different types of organizations. Different approaches to the lifestyle concept are presented in the paper. Also the linkage between the motivation theory, here the Douglas McGregor theory, and the lifestyle based theory VALS is examined.

This paper offers a critical review of the notion of a “singular cognitive role”, which is central to some recent theories of singular thought. According to those theories, whether a thought is singular depends on the role it plays in the subject’s cognitive activity. We compare the two most developed accounts of this type: Crane’s :21–43 2011, The Objects of Thought2013) and Jeshion’s. Both theories aim to capture the notion of a singular cognitive role in terms of mental files. We (...) argue that Jeshion’s theory is much more promising as it provides a more detailed and non-circular characterization of the mental files responsible for singular thinking. We examine the prospects for enhancing that account in light of three major concerns about it present in the literature. First, we discuss whether the weakest aspect of the whole proposal, i.e. the condition for the initiation of mental files, can be replaced without debilitating the rest of the theory. Second, we examine Goodman’s : 437–461 2014, The Philosophical Quarterly2015) argument against mental file theories of singular thought and show that it does not affect Jeshion’s account. Third, we argue against Sawyer :264–283 2012) that Jeshion’s notion of a singular cognitive role is in strong opposition to acquaintance-based theories of singular thought and cannot be incorporated into any of them. Thus, the paper concludes that Jeshion’s proposal, despite its shortcomings, is currently the most promising account of a singular cognitive role. (shrink)

This article argues that if contemporary philosophical counseling wishes to perpetuate the spirit of ancient philosophy, it must also incorporate metaphysics. This kind of incorporation means, among other things, regarding as essential the implementation of the meditation practices of certain historical schools of philosophy. Meditation was an inherent feature not only of Eastern schools of thought, but also within Western philosophy. These practices lead to a psychophysical state, known as ataraxia, which causes the perception of reality to undergo a radical (...) change, including occasional “altered states of consciousness,” as they are known by psychology. The author calls such practices “live metaphysics.” He also maintains that, without the inclusion of such metaphysical practices, philosophical counselling and coaching lose their eudemonic character and become a means of hedonistic gratification in the service of the liberated ego of the contemporary man.

The phenomenon of imaginative resistance occurs when the reader of fiction is invited to imagine as morally right a situation that the reader finds morally repugnant (e.g., that murder is morally good). The problem of imaginative resistance boils down to the question of how it is possible that we can imagine situations that are inconsistent with our knowledge of the facts (magic, teleportation, spaceships moving faster than light), while we have difficulty imagining situations that are inconsistent with our moral knowledge. (...) The purpose of this article is to present two popular concepts that explain the phenomenon of imaginative resistance, the so-called cantian response and the wontian response, and to propose an original solution. The first hypothesis states that imaginative resistance is a response to conceptual impossibility. In this conception, resistance to imagining a particular object or situation comes from the fact that such objects or situations are contradictory and therefore impossible to imagine. The second hypothesis states that imaginative resistance occurs when the recipient does not want to imagine a certain state of affairs. In the last part of the article, I try to show that the source of imaginative resistance can be the inability to imagine oneself as someone with different moral beliefs. (shrink)

The article presents the key problems relevant to the issue of “transcendent Action,” as Peirce calls it. The author focuses on the relation between “belief” and the “transcendentals:” unity, truth, goodness, and beauty, in their peculiar Peirceian context. He considers firstly “belief” in the sense of “an original impulse to act consistently, to have a definite intention” and, secondly, “Normative Science, which investigates the universal and necessary laws of the relation of Phenomena to Ends, that is, perhaps, to Truth, Right, (...) and Beauty.” Finally, he considers Peirce's defense again two popular accusations: one on the part of the logicians which “confounds psychical truths with psychological truths,” and the second one regarding hedonism.

Creature consciousness provides a physicalist account of the first-person awareness. I argue that non-reductive consciousness is not about phenomenal qualia ; it is about the stream of awareness that makes any objects of perception epistemically available and ontologically present. This kind of consciousness is central, internally to one’s awareness. Externally, the feel about one’s significant other’s that “there is someone home” is quite important too. This is not substance dualism since creature consciousness and functional consciousness are both at different generality (...) levels of physicalism. Surprisingly, pre-Hegel philosophy of pure subject is more fitting with the current engineering approach than analytical phenomenalism. The complementary view of subject- and object-related perspectives, may come from Fichte’s Wissenschaftslehre; but here it is placed, securely within the physicalist paradigm. It is essential to the Engineering Thesis in Machine Consciousness, which helps us understand under what general conditions a machine would be first-person conscious, but when it is merely functionally conscious.

There is relatively little literature on Indian skepticism, with hardly any monograph on the subject comparable to, e.g., Julia Annas’ and Jonathan Barnes’ The Modes of Scepticism: Ancient Texts and Modern Interpretations, R.J. Hankinson’s The Sceptics: The Arguments of the Philosophers, a series of Richard H. Popkin’s monographs on the history of skepticism, or two recent competing volumes as collective efforts: The Oxford Handbook of Skepticism edited by John Greco and The Cambridge Companion to Ancient Scepticism edited by Richard Bett. (...) Therefore what promises to provide a survey of the skeptical tradition of South Asia should potentially be regarded as a milestone work in the... (shrink)

This paper develops a proof theory for logical forms of proofs in the case of monadic languages. Among the consequences are different kinds of generalization of proofs in various schematic proof systems. The results use suitable relations between logical properties of partial proof data and algebraic properties of corresponding sets of linear diophantine equations.

The picture of the beginnings of humankind presented by natural science is often contrasted with what is conveyed in Scripture. It has been pointed out that the Edenic state before sin – which we refer to as original justice – was a time of absolute perfection in which there was no room for any deficiency. According to Thomas Aquinas, however, this picture conflicts with what Paradise was as a state on the way to Heaven. For Aquinas, the difference between Paradise (...) and the present situation is not an ontological one but a change of circumstance, because original justice was not a period of salvation. This means that Paradise was a period of development, thanks to the grace received, which is reconcilable with the principled account of natural science. The key is the distinction between Paradise and Heaven, which sets religion–science reflections in their proper context. Contribution: The article drew attention to notions of original justice, emphasising the Paradise time as the development of virtues, including the theological virtue of faith. This helps to build an adequate theological framework for a fruitful dialogue with the natural sciences, as recommended by Buitendag. (shrink)

There are many arguments that so-called pluralistic theologies of religions face difficulties in being sufficiently pluralistic. In order to meet such an objection, a pluralist offers different solutions. I argue that the range of plausible possibilities for a pluralist is strongly constrained by philosophical arguments which one can develop out of the philosophy of Hilary Putnam. In the first part of this paper, I sketch out three important strands of the Putnamian thought I consider worth defending. Given such presuppositions, I (...) formulate two constraints on pluralistic theology of religions. In the last section of my paper, I briefly point out which of the particular standpoints, often labelled as “pluralistic theology of religions,” have problems with meeting formulated constraints, and which of the “pluralists” seem to be in accordance with them.

The concept of informed consent was one of the most fruitful ideas that deeply changed the relationships between physicians and their patients from paternalism to respect for the personal autonomy of subjects needing professional medical care. The great progress in medicine, also involving the pharmaceutical industry, has created an increasing need to perform different clinical and experimental trials. The evolution of clinical research in the last decades has influenced strongly the design of these studies. One of the most important changes (...) in this field has been the use of placebo groups in double-blind controlled studies. The controversies have involved not only the use of placebo when standard or proven treatment was available, but also some specific problems concerning the procedure of obtaining informed consent in such trials. This paper briefly presents the evolution of informed consent in Poland as well as different ethical and legal problems concerning informed consent and the use of placebo controls in clinical trials.

Topic modeling—a text‐mining technique often used to uncover thematic structures in large collections of texts—has been increasingly frequently used in the context of the analysis of scholarly output. In this study, we construct a corpus of 19,488 texts published since 1971 in seven leading journals in the field of bioethics and philosophy of medicine, and we use a machine learning algorithm to identify almost 100 topics representing distinct themes of interest in the field. On the basis of intertopic correlations, we (...) group the content‐based topics into eight clusters, thus providing a novel, fine‐grained intellectual map of bioethics and philosophy of medicine. Moreover, we conduct a number of diachronic analyses, examining how the “prominence” of different topics has changed across time. In this way, we are able to observe the distinct patterns in which bioethics and philosophy of medicine have evolved and changed their focus over the past half a century. (shrink)

This theoretical paper is offered in the spirit of advancing the debate on the socioemotional wealth construct and its impact on how family firms conceptualize and practise corporate social responsibility. The study builds on Kellermanns et al.’s :1175–1182, 2012) claim that the SEW dimensions can be positively and negatively valenced as well as makes a distinction between the selective and instrumental approach to CSR and the holistic and normative one. Drawing on these considerations, it provides a theoretical underpinning in favour (...) of the view that SEW has ambivalent nature and therefore can produce detrimental outcomes for stakeholders of family companies. In this way, the study challenges the implicit assumption prevalent in the literature that SEW is “a prosocial and positive stimulus”. Crucially, it expands on the SEW construct by arguing that, given its ambivalent nature, SEW, as such, is at odds with the “strategic, whole-business view of responsibility”. Consequently, it posits that family firms—because of their concern with SEW—may be more likely to adopt the instrumental and selective rather than strategic and normative approach. Hence, it also makes the case for regarding the latter as a reference point to investigate the family company’s attitude towards social responsibility. It concludes by summarising the argument and offering future research avenues. (shrink)

Blumenthal-Barby and her colleagues (2022) situate their discussion of philosophy and bioethics in the context of (reportedly) widely held assumption that, when compared to the early days of bioethics, the role of philosophy is now diminished across the field – the assumption we call the Disconnection Thesis. This assumption can be summarized, to use the authors’ own words, by the phrase “philosophy’s glory days in bioethics are over“. While in no place of the article they explicitly endorse the Disconnection Thesis, (...) at least some of the authors had previously endorsed it in print (Savulescu 2015). Such expressions of collective expert wisdom might be a valuable source of information on the discipline's history, but they should not be accepted uncritically. Given the explosion in the size and scope of bioethical research in recent decades, any scholar’s familiarity with the area is necessarily based on selective reading and might be biased. Hence, in this commentary, we examine what kind of more rigorous evidence could corroborate the Disconnection Thesis. In other words, if the role of philosophy in bioethics has been indeed diminishing, what kind of observable patterns should we expect to see? Drawing on our previous research (Bystranowski, Dranseika, Żuradzki 2022), here we focus on two useful perspectives: citation analysis and topic modeling. While the first approach allows us to indirectly measure the level of engagement of bioethicists with philosophical literature (by measuring the proportion of references from articles published in journals in bioethics that cite philosophy journals), the latter provides a window into the content and argumentative style of bioethical texts.

The book introduces Tadeusz Kotarbiński’s philosophy of action into the mainstream of contemporary action-theoretical debates. Piotr Makowski shows that Kotarbiński–Alfred Tarski’s teacher and one of the most important philosophers of the renowned Lvov-Warsaw school—proposed a groundbreaking, original, and (in at least a few respects) still fresh perspective in action theorizing. The book examines and develops Kotarbiński’s ideas in the context of the most recent discussions in the philosophy of action. The main idea behind Kotarbiński’s action theory—and thus, behind this (...) book—is the significance of the philosophical investigations of the general conditions of effectiveness, efficiency, and economy of intentional actions. Makowski presents and reinterprets Kotarbiński’s views on these dimensions of our activities and sheds new light on the most important areas of action theory. (shrink)

Rozprawa Doktora Piotra Domerackiego zatytułowana Horyzonty i perspektywy monoseologii. Filozoficzne studium samotności stanowi ciekawą i oryginalną propozycję intelektualną. Jako oczywiste plusy przedstawionego opracowania wskazać należy oryginalność tematyki, rozległość studiów oraz dojrzały charakter refleksji autora. Samotność stanowi temat ciągle aktualny i powracający, a jednocześnie zaskakujący złożonością i wielowymiarowością. Jest to przy tym temat, który prowokuje do pytań o naszą własną tożsamość, stanowi punkt wyjścia dla autoanalizy i pytania o relacje z innymi. Odpowiedzi na pytanie o mechanizm rozprzęgania się tych więzi i (...) konsekwencje tych procesów dla człowieka ukazują paradoksy i sprzeczności myślenia o tym zagadnieniu. […] W przedstawionym opracowaniu dr Piotr Domeracki podejmuje ogromny wysiłek przedstawienia całej tej złożoności i wewnętrznych napięć organizujących badania i refleksję nad samotnością. Realizując podjęte zadanie, Autor odnosi wiele sukcesów. Z recenzji wydawniczej dr hab. Heleny Ciążeli, prof. APS, Warszawa Wszelki system wiedzy o samotności, jeśli aspiruje do zupełności oraz jeśli ma być wiarygodny, miarodajny i funkcjonalny, powinien być komplementarny, to znaczy powinien umiejętnie łączyć minimalistyczną oraz maksymalistyczną (w sensie Walzerowskim) perspektywę oglądu i deskrypcji. Zasadniczą trudnością w precyzyjnym i kompleksowym opisie samotności jest jej wysoce ograniczona komunikowalność na poziomie doznaniowości. Samotność jest bowiem niezwykle oporna wobec możliwości empatycznego jej współprzeżywania. Z tego powodu jawi się ona jako agregat takich negatywnie percypowanych własności i określeń, jak monadyczność, solipsystyczność, apatyczność, autystyczność czy outsiderstwo. Zasadniczym celem niniejszej monografii – oprócz intencji wyłożenia i popularyzacji standardów wiedzy monoseologicznej – jest dążenie do przedstawienia jak najszerszego spektrum problemowego oraz siatki pojęciowej filozofii samotności.
