We investigate a generalization of discrete-time integrator. Proposed linear discrete-time integrator is characterised by the variable, fractional order of integration/summation. Graphical illustrations of an analysis of particular vector matrices are presented. In numerical examples, we show relations between the order functions and element responses.
Predictive processing (PP) has been repeatedly presented as a unificatory account of perception, action, and cognition. In this paper, we argue that this is premature: As a unifying theory, PP fails to deliver general, simple, homogeneous, and systematic explanations. By examining its current trajectory of development, we conclude that PP remains only loosely connected both to its computational framework and to its hypothetical biological underpinnings, which makes its fundamentals unclear. Instead of offering explanations that refer to the same set of (...) principles, we observe systematic equivocations in PP‐based models, or outright contradictions with its avowed principles. To make matters worse, PP‐based models are seldom empirically validated, and they are frequently offered as mere just‐so stories. The large number of PP‐based models is thus not evidence of theoretical progress in unifying perception, action, and cognition. On the contrary, we maintain that the gap between theory and its biological and computational bases contributes to the arrested development of PP as a unificatory theory. Thus, we urge the defenders of PP to focus on its critical problems instead of offering mere re‐descriptions of known phenomena, and to validate their models against possible alternative explanations that stem from different theoretical assumptions. Otherwise, PP will ultimately fail as a unified theory of cognition. (shrink)
The widespread idea that infinitesimals were “eliminated” by the “great triumvirate” of Cantor, Dedekind, and Weierstrass is refuted by an uninterrupted chain of work on infinitesimal-enriched number systems. The elimination claim is an oversimplification created by triumvirate followers, who tend to view the history of analysis as a pre-ordained march toward the radiant future of Weierstrassian epsilontics. In the present text, we document distortions of the history of analysis stemming from the triumvirate ideology of ontological minimalism, which identified the continuum (...) with a single number system. Such anachronistic distortions characterize the received interpretation of Stevin, Leibniz, d’Alembert, Cauchy, and others. (shrink)
Piotr Kropotkin był najważniejszym przedstawicielem tzw. darwinizmu rosyjskiego oraz teorii pomocy wzajemnej, która podkreślała znaczenie współpracy wewnątrzgatunkowej w procesie doboru naturalnego oraz walki o byt. Na jej kanwie rosyjski badacz wysunął tezę o ewolucyjnych źródłach moralności, będącej problem badawczym w niniejszym artykule. Stanowi to jednocześnie powód dlaczego poza przedstawieniem wspomnianej tezy i jej założeń, w publikacji zilustrowana została także teoria pomocy wzajemnej. Zaproponowana przez Kropotkina wizja moralności suponowała, iż stanowi ona „przyrodzoną” właściwość ludzkiej natury. Podstawę dla niej stanowić ma (...) instynkt społeczny oraz jego przejawy, takie jak: równość, solidarność, sprawiedliwość, itd., a także pomoc wzajemna. Stawiało to propozycję rosyjskiego darwinisty w opozycji wobec dominujących trendów w myśleniu o ludzkiej moralności na przełomie XIX i XX wieku, zwłaszcza wobec tzw. darwinizmu społecznego i charakterystycznego dlań dualizmu moralnego. Ponadto zrywała z antropocentryzmem zakładając, iż poza gatunkiem ludzkim, także inne gatunki cechują się uczuciami moralnymi. (shrink)
Abraham Robinson’s framework for modern infinitesimals was developed half a century ago. It enables a re-evaluation of the procedures of the pioneers of mathematical analysis. Their procedures have been often viewed through the lens of the success of the Weierstrassian foundations. We propose a view without passing through the lens, by means of proxies for such procedures in the modern theory of infinitesimals. The real accomplishments of calculus and analysis had been based primarily on the elaboration of novel techniques for (...) solving problems rather than a quest for ultimate foundations. It may be hopeless to interpret historical foundations in terms of a punctiform continuum, but arguably it is possible to interpret historical techniques and procedures in terms of modern ones. Our proposed formalisations do not mean that Fermat, Gregory, Leibniz, Euler, and Cauchy were pre-Robinsonians, but rather indicate that Robinson’s framework is more helpful in understanding their procedures than a Weierstrassian framework.

The truly philosophical issue in machine conscioiusness is whether machines can have 'hard consciounsess'. Criteria for hard consciousness are higher than for phenomenal consciousness, since the latter incorporates first-person functional consciousness.
Foundations of Science recently published a rebuttal to a portion of our essay it published 2 years ago. The author, G. Schubring, argues that our 2013 text treated unfairly his 2005 book, Conflicts between generalization, rigor, and intuition. He further argues that our attempt to show that Cauchy is part of a long infinitesimalist tradition confuses text with context and thereby misunderstands the significance of Cauchy’s use of infinitesimals. Here we defend our original analysis of various misconceptions and misinterpretations concerning (...) the history of infinitesimals and, in particular, the role of infinitesimals in Cauchy’s mathematics. We show that Schubring misinterprets Proclus, Leibniz, and Klein on non-Archimedean issues, ignores the Jesuit context of Moigno’s flawed critique of infinitesimals, and misrepresents, to the point of caricature, the pioneering Cauchy scholarship of D. Laugwitz. (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)
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)
Was Heidegger a 'realist' or an 'idealist'? The issue has been and continues to be hotly debated in Heidegger scholarship. Here it is argued that the much more desirable realistic interpretation of Heidegger can be sustained, provided his theory of moods is given its due. Moods, I argue, are not only 'equiprimordial' with Dasein's understanding of being, but are also irreducible to the latter. It is often held - correctly, as it seems to the author - that Heidegger's idealism is (...) all but inevitable if Dasein's awareness of entities is grounded only in Dasein's understanding of being. But in Being and Time Heidegger speaks also of how what there is is 'disclosed moodwise'. The essay closely analyzes this specifically moody mode of disclosure, and shows both its autonomy vis-à-vis the understanding of being and its function of securing, for Dasein, an access to a truly independent reality.

The article presents the question of understanding divine causality and its analogical character in the context of Thomas Aquinas’s teaching on Divine Providence. Analyzing Aquinas’s texts concerning the relation of God’s action towards nature and its activities it is necessary to emphasize the proper understanding of mutual relations between secondary causes and the primary cause which are not on the same level. Influenced by the reflection of M. Dodds and I Silva, the author of the article refers to Aquinas’s biblical (...) commentaries which have not been discussed so far from the perspective of the character of God’s action. In the final part of the article, metaphors used by Thomas in reference to the relation of God towards the world will be presented. (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.

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)
To explore the extent of embeddability of Leibnizian infinitesimal calculus in first-order logic (FOL) and modern frameworks, we propose to set aside ontological issues and focus on pro- cedural questions. This would enable an account of Leibnizian procedures in a framework limited to FOL with a small number of additional ingredients such as the relation of infinite proximity. If, as we argue here, first order logic is indeed suitable for developing modern proxies for the inferential moves found in Leibnizian infinitesimal (...) calculus, then modern infinitesimal frameworks are more appropriate to interpreting Leibnizian infinitesimal calculus than modern Weierstrassian ones.

Predictive processing models of psychopathologies are not explanatorily consistent with the present account of abstract thought. These models are based on latent variables probabilistically mapping the structure of the world. As such, they cannot be informed by representational ontology based on mental objects and states. What actually is the case is merely some terminological affinity between subjective and informational uncertainty.
In their insightful article, Brent Kious and Margaret Battin (2019) correctly identify an inconsistency between an involuntary psychiatric commitment for suicide prevention and physician aid in dying (PAD). They declare that it may be possible to resolve the problem by articulating “objective standards for evaluating the severity of others’ suffering,” but ultimately they admit that this task is beyond the scope of their article since the solution depends on “a deep and difficult” question about comparing the worseness of two possible (...) scenarios: letting someone die (who could have been helped) with not letting someone die (whose suffering could only be alleviated by death). In our commentary, we argue that creating such standards is more difficult than the authors assume because of the many types of deep uncertainties we have to deal with: (1) diagnostic, (2) motivational, and (3) existential.

This paper discusses differences between two major schools in philosophy of criminal law, retributivism and consequentialism, with regard to the risk of punishing the innocent. As it is argued, the main point of departure between these two camps in this respect lies in their attitude towards the high evidentiary threshold in a criminal trial: while retributivism seems to strongly support setting this standard high, consequentialists may find it desirable to relax it in some cases. This discussion is set in the (...) context of proxy criminalization, i.e. a situation, in which some suspicious behaviour is criminalized. Since proxy criminalization may be understood as an effective lowering of the evidentiary threshold, its employment is justifiable from the consequentialist perspective, while being highly problematic for the retributivists.

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)
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)
A calculus of names is a logical theory describing relations between names. By a pure calculus of names we mean a quantifier-free formulation of such a theory, based on classical propositional calculus. An axiomatisation of a pure calculus of names is presented and its completeness is discussed. It is shown that the axiomatisation is complete in three different ways: with respect to a set theoretical model, with respect to Leśniewski's Ontology and in a sense defined with the use of axiomatic (...) rejection. The independence of axioms is proved. A decision procedure based on syntactic transformations and models defined in the domain of only two members is defined. (shrink)
L’article aborde la problématique des actes normatifs de droit pénal adoptés en Pologne dans les années 1944–1956. L’auteur essaie de répondre à la question : comment le régime politique et l’idéologie stalinienne ont-ils influencé la manière de rédiger les textes juridiques de cette branche du droit lors des plus grandes répressions par le pouvoir d’après-guerre en Pologne? À partir de 1944, le droit pénal a été adapté aux besoins des autorités communistes, contrôlées par l’Union soviétique. Dans la période analysée, on (...) a introduit en Pologne plus de cent actes normatifs englobant des dispositions pénales. L’idéologisation du droit pénal est visible dans toutes les parties des actes normatifs : titres, préambules et dispositions juridiques. On retrouve dans leur contenu les valeurs politiques, économiques et sociales fondamentales pour l’idéologie du stalinisme, dont les thèses ont été mises en œuvre en Pologne après la fin de l’occupation allemande.

Successful social functioning requires quick and accurate processing of emotion and generation of appropriate reactions. In typical individuals, these skills are supported by embodied processing, recruiting central and peripheral mechanisms. However, emotional processing is atypical in individuals with autism spectrum disorder (ASD). Individuals with ASD show deficits in recognition of briefly presented emotional expressions. They tend to recognize expressions using rule-based, rather than template, strategies. Individuals with ASD also do not spontaneously and quickly mimic emotional expressions, unless the task encourages (...) engagement. When processing emotional scenes, ASD individuals show atypical basic motivational responses, despite intact ability to verbally determine stimulus valence. We discuss how these findings highlight the contribution of both embodied and disembodied mechanisms to typical and atypical emotional functioning. (shrink)
This article introduces a model of levels of analysis applied to statements found in philosophical, scientific, and religious discourses in order to facilitate a more accurate description of the relation between science and religion. The empirical levels prove to be the most crucial for the relation between science and religion, because they include statements that are important parts of both scientific and religious discourse, whereas statements from metaphysical levels are only important in terms of religion and are neutral in relation (...) to particular scientific theories. In particular, the rejection of certain ontological assumptions behind special divine action logically entails the rejection of the literal meaning of empirical statements describing special open expression of supernatural factors in nature. Such a rejection also entails an essential revision of many religious systems of beliefs, including traditional Christian theism. (shrink)
The paper presents an overview of research on working memory as a predictor of early school achievements. We contrast two main areas of research on the role of working memory in school achievements: the first concerns the structural model of working memory and the second focuses on executive functions. Then, we discuss the facet model of working memory as a promising approach merging the two research branches on working memory tasks as predictors of early school achievements. At the end we (...) present exemplary results of the research conducted on a national sample of six- and seven-year-olds in Poland, which indicates strong relation of working memory functions with the measures of competences in mathematics, reading, and writing. Additionally, the mediation analyses, with parents’ education as a covariate, indicate that the influence of age on achievements in math, reading, and writing in six- and seven-year olds is mediated by working memory functions.

Following on the arguments adumbrated in his previous works, Piotr Hoffman here argues that the notion of and concern with violence are not limited to political philosophy but in fact form the essential component of philosophy in general. The acute awareness of the ever-present possibility of violence, Hoffman claims, filters into and informs ontology and epistemology in ways that require careful analysis. In his previous book, Doubt, Time, Violence , Hoffman explored the theme of violence in relation to Descartes' (...) problematic of doubt and Heidegger's work on temporality. The pivotal notion deriving from that investigation is the notion of the other as the ultimate limit of one's powers. In effect, Hoffman argues, our practical mastery of the natural environment still leaves intact the limitation of human agents by each other. In a violent environment, the other emerges as an insurmountable obstacle to one's aims and purposes or as an inescapable danger which one is powerless to hold at bay. The other is thus the focus of an ultimate resistance to one's powers. The special status of the other, as Hoffman articulates it, is at the root of several key notions around which modern philosophy has built its problematic. Arguing here that when the theme of violence is taken into account many conceptual tensions and puzzles receive satisfying solutions, Hoffman traces the theme through the issue of things versus properties; through Kant's treatment of causality, necessity, and freedom in the Critique of Pure Reason; and through the early parts of Hegel's Logic. The result is a complete reorientation and reinterpretation of these important texts. Violence in Modern Philosophy offers patient and careful textual clarification in light of Hoffman's central thesis regarding the other as ultimate limit. With a high level of originality, he shows that the theme of violence is the hidden impulse behind much of modern philosophy. Hoffman's unique stress on the constitutive importance of violence also offers a challenge to the dominant "compatibilist" tradition in moral and political theory. Of great interest to all philosophers, this work will also provide fresh insights to anthropologists and all those in the social sciences and humanities who occupy themselves with the general theory of culture.

This article focuses on Bob Zajonc’s views on unconscious emotion, especially in the context of the debates about the independence of affect and cognition. Historically, Bob was always interested in the “mere”—basic, fundamental processes. His empirical demonstrations of precognitive and preconscious emotional processes, combined with his elegant expositions of them, sharply contrasted with cold and complex cognitive models. Interestingly, Bob tended to believe that whereas the causes of emotion can be unconscious, the emotional state itself tends to be conscious. However, (...) he reconsidered this assumption and in his later work showed that subjects in affective priming experiments do not experience conscious affect, but instead act on basic preferences. Today, Bob’s insights continue to inspire research on “unconscious emotion.”. (shrink)
In this original analysis, Hoffman shows how the modern self's drive for total autonomy and independence defines the relations of human selves as essentially violent. He further argues that the notion of violence underlies some of the key components of mainstream modern philosophizing.

ABSTRACT The following text is a large fragment of the lectures on heresy that Leszek Kołakowski gave between November 1982 and February 1983 on the Polish radio station Radio Free Europe. These lectures have never been published in English. They were only published under the title ‘Herezja’ in Poland after the author’s death in 2010 by the publishing company Znak. Kołakowski raises the universal and timeless issues of tolerance, ideological struggles, protection of doctrine by religious institutions and the changing attitude (...) of the Catholic Church towards heretical challenges. The concept of heresy is an opportunity to describe the history of ideological conflicts, show how they arise and how they can be resolved. The story of struggle between dogmatists and heretics is an endless story of changing social order and giving new shapes to the reality created by people and their ideas. Kołakowski points out that any doctrinal, political or ideological system must allow for criticism and otherness. Nearly 40 years after these lectures were given, they retain a special freshness in the context of the political, ideological and social crisis that Europe is experiencing in the early twenty-first century.

The process of continuing education of paramedics is based on gaining educational credits during five-year educational periods. One of the forms of self-improvement are Internet-based educational programs. The lack of regulations concerning the organizational and technical aspects of e-learning made the authors attempt to analyze the phenomenon. The aim of the article is to present an initial analysis of the role of online educational programs in comparison with other forms of professional training of paramedics. One in three respondents has recently (...) used one of the methods of distance learning. Despite the low awareness of the effectiveness of e-learning, almost 70% of the interviewees expressed a positive opinion about it and over 50% were willing to use such forms in the future. The respondents preferred online trainings in the asynchronous version, containing audio-visual materials and providing the possibility to obtain a certificate issued to the participant after completing the course. The demand for topics in the area of professional training included mainly the fields of Drug Therapy, electrotherapy, electrocardiogram evaluation, medical segregation, and help in delivery in pre-hospital conditions. Modern forms of distance learning do not make it possible to acquire practical skills, yet their role in professional training of paramedics is still significant. According to the authors, online educational programs constitute an effective complement to traditional training through the performance of tasks in a mixed form, known as blended-learning. (shrink)
Two eight-century Jaina contemporaries, a Śvetāmbara philosopher Siddhasena Mahāmati and a Digambara Akalaṅka Bhaṭṭa revolutionised Jaina epistemology, by radically transforming basic epistemological concepts, which had been based on canonical tradition. The paper presents a brief historical outline of the developments of basic epistemological concepts in Jaina philolosophy such as the cognitive criterion and logical faculties as well as their fourteen typological models which serve as the backdrop of important innovations in epistemology introduced by Siddhasena, Pātrasvāmin and Akalaṅka. An important contribution (...) of these Jaina thinkers was to economize Indian logic and the rules of inference, first, by devising only one kind of logical reason called ‘inexplicability otherwise’, based on the single inseparable connection of the proving property with the inferable property, and, second, by limiting the necessary number of the members of the proof formula merely to two. These two innovations were related to the thinkers’ intention to devise a logic which would not primarily be based on empirical verification but its structural patterns would be valid irrespective of external observation. Further, the paper focuses on the nature of the epistemological shifts which Siddhasena and Akalaṅka introduced independently of each other and on the question how Siddhasena’s and Akalaṅka’s ideas were partly anchored in Buddhist concepts of the pramāṇa school of Diṅnāga and Dharmakīrti. With the Buddhist background, Siddhasena sought to define the criteria essential to distinguish true from false cognitions and to provide a novel classification of the pramāṇas. He can further be accredited with formulating the first Jaina descriptive definition of the cognitive criterion. The final section of the paper explains how Akalaṅka applies novel epistemological ideas, first, to construct realistic ontology and objectivity of both the external world and the cognising subject, and, secondly, to combat fundamental Buddhist concepts such as idealism and momentariness.

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)
In this article, I examine Michael Bratman’s account of stability in his planning theory of intention. Future-directed intentions should be stable, or appropriately resistant to change, over time. Bratman claims that the norm of stability governs both intentions and plans. The aim of this article is to critically enrich Bratman’s account of stability by introducing plasticity as an additional norm of planning. I construct plasticity as a kind of stability of intentions which supplements Bratman’s notion of “reasonable stability.” Unlike the (...) latter, plasticity applies mainly to cases in which plan states are abandoned without reconsideration. I focus on the intra-theoretical problems of PTI and elucidate: the distinction between future-directed intentions and plans, the conceptual difference between stability and inertia, which is only implicit in PTI, and the role of the environment of the planner, which has a vestigial role in Bratman’s work. I also defend my incorporation of pl... (shrink)
