The study of the chaotic dynamics in fractional-order discrete-time systems has received great attention over the last years. Some efforts have been also devoted to analyze fractional maps with special features. This paper makes a contribution to the topic by introducing a new fractional map that is characterized by both particular dynamic behaviors and specific properties related to the system equilibria. In particular, the conceived one dimensional map is algebraically simpler than all the proposed fractional maps in the literature. Using (...) numerical simulation, we investigate the dynamic and complexity of the fractional map. The results indicate that the new one-dimensional fractional map displays various types of coexisting attractors. The approximate entropy is used to observe the changes in the sequence sequence complexity when the fractional order and system parameter. Finally, the fractional map is applied to the problem of encrypting electrophysiological signals. For the encryption process, random numbers were generated using the values of the fractional map. Some statistical tests are given to show the performance of the encryption. (shrink)

One of the unresolved issues in Aristotle’s hylomorphism is the part-whole puzzle. Some scholars suppose that in Metaphysics Z 17, 1041b11-33 he endorses non-mereological hylomorphism. This kind of interpretation, however, has been challenged by K. Koslicki who argues that if the evidence in Metaphysics Z 17 is combined with some related textual and conceptual considerations, then a convincing case can be made for a mereological construal of Aristotelian hylomorphism. This paper does four things. First, it scrutinizes these opposing approaches to (...) Aristotle’s theory. Second, it suggests that to adjudicate the dispute at hand one ought to determine how Aristotle deals with what has come to be known as ‘Ackrill’s problem’. It is proposed that if we consider Aristotle’s theory in light of some distinctions drawn in contemporary discussions of hylomorphism, then it transpires that he does have a solution to Ackrill’s problem. Third, it is shown that his solution to this problem suggests a particular way of settling the debate over the part-whole puzzle. And finally, it is argued that the suggested reconstruction of Aristotelian hylomorphism is consistent with the textual evidence in Metaphysics Z 17 and its associated texts. (shrink)

Weak filters were introduced by K. Schlechta in the ’90s with the aim of interpreting defaults via a generalized ‘most’ quantifier in first-order logic. They arguably represent the largest class of structures that qualify as a ‘collection of large subsets’ of a given index set |$I$|⁠, in the sense that it is difficult to think of a weaker, but still plausible, definition of the concept. The notion of weak ultrafilter naturally emerges and has been used in epistemic logic and other (...) knowledge representation (KR) applications. We provide a comprehensive exposition of weak filters and ultrafilters, comparing them with their classical counterparts that have found very important applications in logic, set theory and topology. Weak (ultra)filters capture the ‘majorities’ of social choice theory (which coincide with the commonsense understanding of a ‘large subset’) and in that respect, they outperform classical (ultra)filters in their role as ‘collections of large subsets’. Yet, they lack some of the elegant properties of classical (ultra)filters that make them an almost perfect match for logical theories. We investigate the extent to which some important classical results carry through in this new setting, and we focus on genuinely weak filters and genuinely weak ultrafilters. For weak ultrafilters, we proceed to provide concrete examples, answer questions of existence and characterize their construction. The class of weak (ultra)filters represents a genuine contribution of KR to set theory that might be of some interest to set theorists too and we initiate this study by providing a glimpse on natural set-theoretic questions.

The goal of perception is to infer the most plausible source of sensory stimulation. Unisensory perception of temporal order, however, appears to require no inference, since the order of events can be uniquely determined from the order in which sensory signals arrive. Here we demonstrate a novel perceptual illusion that casts doubt on this intuition: in three studies (N=607) the experienced event timings are determined by causality in real-time. Adult observers viewed a simple three-item sequence ACB, which is typically remembered (...) as ABC (Bechlivanidis & Lagnado, 2016), in line with principles of causality. When asked to indicate the time at which events B and C occurred, points of subjective simultaneity shifted so that the assumed cause B appeared earlier and the assumed effect C later, despite full attention and repeated viewings. This first demonstration of causality reversing perceived temporal order cannot be explained by post-perceptual distortion, lapsed attention, or saccades. (shrink)

Combining philosophical and political analysis, this study offers a comprehensive reassessment of Castoriadis' contribution to critical theory in and through his critical confrontation with both the crisis of the traditional Left and the crisis of modern capitalist societies. The key concepts of 'crisis' and 'critique' are considered throughout the text and Castoriadis' ideas are situated in a critical debate with other radical thinkers, such as Lefort, Pannekoek, Arendt, Althusser, Axelos, Papaioannou and Marx. The study supplies an extensive analysis and explores (...) the contemporary relevance of Castoriadis' views regarding the Russian Revolution of 1917, the Hungarian revolt of 1956 and the events of May 1968 in France. It argues for a re-radicalization of his thought in light of the current capitalist crisis and seeks to trace his radical alternative to crisis by critically examining and further elaborating his positions with respect to socialism, autonomy and revolution.

An Introduction to basic metaepistemological debates and positions.

Metaepistemology Metaepistemology is, roughly, the branch of epistemology that asks questions about first-order epistemological questions. It inquires into fundamental aspects of epistemic theorizing like metaphysics, epistemology, semantics, agency, psychology, responsibility, reasons for belief, and beyond. So, if as traditionally conceived, epistemology is the theory of knowledge, metaepistemology is the theory of the theory of knowledge. … Continue reading Metaepistemology →.

Perceptual experience is one of our fundamental sources of epistemic justification—roughly, justification for believing that a proposition is true. The ability of perceptual experience to justify beliefs can nevertheless be questioned. This article focuses on an important challenge that arises from countenancing that perceptual experience is cognitively penetrable. -/- The thesis of cognitive penetrability of perception states that the content of perceptual experience can be influenced by prior or concurrent psychological factors, such as beliefs, fears and desires. Advocates of this (...) thesis could for instance claim that your desire of having a tall daughter might influence your perception, so that she appears to you to be taller than she is. Although cognitive penetrability of perception is a controversial empirical hypothesis, it does not appear implausible. The possibility of its veracity has been adduced to challenge positions that maintain that perceptual experience has inherent justifying power. -/- This article presents some of the most influential positions in contemporary literature about whether cognitive penetration would undermine perceptual justification and why it would or would not do so. -/- Some sections of this article focus on phenomenal conservatism, a popular conception of epistemic justification that more than any other has been targeted with objections that adduce the cognitive penetrability of experience.

Studies document that in wartime, states often employ maternal imagery and mobilize women as mothers.Yet we know relatively little about when and why states and their opposition do so. This study seeks to build theory for this phenomenon through frame analysis of the Nicaraguan Contra War. The author proposes that maternal framing, aimed at mothers as well as a broader national and international audience, benefits militaries in at least three ways: channeling maternal grievances, disseminating propaganda through “apolitical” mothers, and evoking (...) emotions and sympathy nationally and internationally. This study furthermore explores three underexamined features of both gendered studies of war and frame analysis: It applies frame theory to states, it develops our understanding of crossnational gendered framing strategies, and it introduces gender framing to the study of war.

A sample of 259 South African managers completed a survey originally administered by Nel (1992). The results of the current study indicated a favourable move on four of the 15 questionable actions used to assess each group's ethical predisposition. Furthermore, the grand means for the two temporal-based samples also provided anecdotal evidence of a positive transition. Virtually identical results were in evidence when the segment of 89 top managers was compared to the sample of its higher level peers from the (...) earlier study by Nel. The results support the premise that today's South African managers have a more ethical predisposition than did their peers of some 20 years prior to them. However, the study concurrently documents the reality that there is ample room for further improvement. (shrink)

I sketch an interpretation of Tolstoy’s implicit moral theory on the basis of his masterpieces War and Peace and Anna Karenina. I suggest that Tolstoy is a theistic moral realist who believes that God’s will identifies the mind-independent truths of morality. He also thinks that, roughly, it suffices to heed natural moral emotions (like love and compassion) to know the right thing to do, that is, God’s will. In appraisal of Tolstoy’s interesting and original theory that I dub ‘theistic populist (...) sentimentalism’, I argue that it prima facie runs into a string of fallacies and undertakes dubious assumptions that render it open to question.

The objective of this paper is to articulate a distinction between habit and bodily skill as different ways of acting without deliberation. I start by elaborating on a distinction between habit and skill as different kinds of dispositions. Then I argue that this distinction has direct implications for the varieties of automaticity exhibited in habitual and skilful bodily acts. The argument suggests that paying close attention to the metaphysics of agency can help to articulate more precisely questions regarding the varieties (...) of automaticity exhibited in overt action.

Expressivism is a blossoming meta-semantic framework sometimes relying on what Carter and Chrisman call “the core expressivist maneuver.” That is, instead of asking about the nature of a certain kind of value, we should be asking about the nature of the value judgment in question. According to expressivists, this question substitution opens theoretical space for the elegant, economical, and explanatorily powerful expressivist treatment of the relevant domain. I argue, however, that experimental work in cognitive psychology can shed light on how (...) the core expressivist maneuver operates at the cognitive level and that this: raises worries about the aptness of the expressivist question substitution and supports an evolutionary debunking argument against expressivism. Since evolutionary debunking arguments are usually run in favor of expressivism, this creates an obvious puzzle for expressivists. I wrap up by briefly responding to the objection that the debunking argument against expressivism overgeneralizes and, therefore, should be rejected. (shrink)

This book offers the first comprehensive assessment of Heidegger’s account of affective phenomena. Affective phenomena play a significant role in Heidegger’s philosophy — his analyses of mood significantly influenced diverse fields of research such as existentialism, hermeneutics, phenomenology, theology and cultural studies. Despite this, no single collection of essays has been exclusively dedicated to this theme. Comprising twelve innovative essays by leading Heidegger scholars, this volume skilfully explores the role that not only Angst plays in Heidegger’s work, but also love (...) and boredom. Exploring the nature of affective phenomena in Heidegger, as well as the role they play in wider philosophical debates, the volume is a valuable addition to Heideggerian scholarship and beyond, enriching current debates across disciplines on the nature of human agency.

A survey of basic metaepistemological positions and debates.

Dans ce livre un heritage est deliberement assume: celui de la linguistique structurale et fonctionnelle, celle qui, en Europe, s'inscrit dans la tradition saussurienne et pragoise. A la lumiere d'une experience d'une trentaine d'annees qui associe etroitement la recherche fondamentale en theorie linguistique et la pratique de la description des langues les plus diverses, l'auteur propose les innovations theoriques et methodologiques qui lui semblent necessaires pour maintenir une linguistique fonctionnelle dans le respect du reel et permettre a tous ceux qui (...) le souhaiteront d'acceder a la veritable organisation des langues et a leur dynamique interne. Les problemes abordes touchent a la phonologie, a la syntaxe, a la typologie ainsi qu'au processus de disparition des langues. Mettant en oeuvre une linguistique qui se veut resolument moderne, l'auteur pose le principe d'inachevement comme horizon symbolique d'une discipline qui ne saurait oublier que les faits de langue sont inexorablement lies a des faits de societe et reste ainsi tributaire de ces limites.

In his 1988 University Lecture in Religion at Arizona State University, Josef van Ess argued for a widespread concept of a “compact” God in early Islam. The notion is expressed by ṣamad in Sura 112.2, an enigmatic word, which “in the first half of the second Islamic century … was understood as meaning ‘massive, compact.’” There is Islamic evidence for this, van Ess argued: “The best testimony, however, comes from outside Islam: Theodore Abū Qurra, bishop of Ḥarrān in Upper Mesopotamia (...) , translated ṣamad into Greek as sphyropēktos, a quite unusual word meaning something like ‘hammered together, closely united.’ Nicetas of Byzantium later on used holosphyros instead, ‘entirely chased in metal.’” Those familiar with the negative reception of these Byzantine translations of ṣamad by several scholars will undoubtedly be surprised by van Ess's statement, which considers the translations as trustworthy testimony. When John Meyendorff had earlier wondered tentatively whether some Byzantine interpretations of Islamic doctrine, including God sphyropēktos or holosphyros, could “in fact come from some forms of popular Arab religion—distinct, of course, from orthodox Islam—which were known to the Byzantines,” his thought was called “provocative.” Scholars translate sphyropēktos as “beaten solid into a ball” or “solid ” and holosphyros as “of hammer-beaten metal” , “made of solid, hammer-beaten metal” , “impenetrable” , or “made of solid metal beaten to a spherical shape” . They are often inclined to assume that the Greek words represent “a clumsy translation” , “a blatant, derogatory mistranslation of the divine epithet ṣamad” , “the result of a biased attitude and wrong interpretation of the Qur՚anic proclamation of Allah” , or “one of the stock examples in Christian polemics against Islam” or that they were “probably originally chosen for polemical reasons, to claim that Muslims believe in a material, corporeal God” . Perhaps under the impression of these views, in his recent translation of Theodore Abū Qurrah, John C. Lamoreaux, instead of sphyropēktos, adopts a variant reading, steiropēktos , meaning “barren-built.”. (shrink)

With contributions from a number of pioneering researchers in the field, this collection is aimed not only at researchers and scientists in nonlinear dynamics but also at a broader audience interested in understanding and exploring how modern chaos theory has developed since the days of Poincaré. This book was motivated by and is an outcome of the CHAOS 2015 meeting held at the Henri Poincaré Institute in Paris, which provided a perfect opportunity to gain inspiration and discuss new perspectives on (...) the history, development and modern aspects of chaos theory. Henri Poincaré is remembered as a great mind in mathematics, physics and astronomy. His works, well beyond their rigorous mathematical and analytical style, are known for their deep insights into science and research in general, and the philosophy of science in particular. The Poincaré conjecture (only proved in 2006) along with his work on the three-body problem are considered to be the foundation of modern chaos theory. (shrink)

In the first months of the COVID-19 pandemic, we created and implemented from November 2020 to February 2021 a monthly educational pilot program of philosophical management of stress based on Science, Humanism and Epicurean Pragmatism, which was offered to employees of 26 municipalities in the Prefecture of Attica, Greece. The program named “Philosophical Distress Management Operation System” (Philo.Di.M.O.S.) is novel and unique in its kind, as it combines a certain Greek philosophical tradition (Epicurean) that concurs with modern scientific knowledge. The (...) program was designed to be implemented in a period of crisis; therefore, it used a fast-paced, easy to learn and practice philosophical approach to stress management, based on cognitive psychotherapy. The philosophical approach to stress management has the advantage that it can be offered to most people, regardless of age and educational level. The pilot program was effective in achieving its objectives, shown by statistical comparisons of the trainees’ responses to anonymous questionnaires before and after the month-long training. The successful Philo.Di.M.O.S. program, thus, based on a solid scientific and philosophical basis, offers a paradigm of stress management during crises and could be useful in Greece and internationally.

The intellectual ferment that emerged in postwar France was marked by the renaissance of Hegel’s thought and the focus on Marx's early writings. In a parallel way, the death of Stalin, the uprising of 1953 in East Germany and the revolts in Hungary and Poland in 1956 provoked a thorough critique against the theory and practice of orthodox Marxism. The relationship between Marx and Marxism or the issue about the philosophical foundations of Marx’s thinking became the subject of long-standing controversy (...) and gave rise to several interpretations of Marx’s work. These debates were decisively fostered by the foreign intellectuals and refugees who arrived in France after the end of the Second World War; inter alia, a generation of young Greek intellectuals that included the prominent figures of Kostas Axelos, Cornelius Castoriadis and Kostas Papaioannou. This article focuses on Axelos’, Castoriadis’ and Papaioannou’s critique of Marx and provides an anti-critique of their intellectual endeavour. It outlines the common basis of their critical confrontation with the Marxian theorizing and argues that they interpreted Marx’s thought in a manner similar to orthodox Marxism. Despite the undoubted merits of their critique, they did not take it to all its theoretical and political conclusions. As a result, the horizons they opened lack radicalism and their dialogue with Marx was left open to being misunderstood. (shrink)

In this paper, we propose that economic sustainability is seen in terms of (inter-temporal and inter-national) value creation. We claim that value appropriation (or capture), can become a constraint to economic sustainability. We propose that for sustainable value creation to be fostered, corporate governance needs to be aligned to public and supra-national governance. In order to achieve this, a hierarchically layered set of ‘agencies’, needs to be diagnosed and the issue of incentive alignment addressed. Enlightened self-interest, pluralism and diversity, as (...) well as a representative supra-national organisation for world-wide economic sustainability can serve as a new, more ‘ethically correct’ governance for economic sustainability, but not a panacea.

Several authors have argued that the things one does in the course of skilled and habitual activity present a difficult case for the ‘standard story’ of action. They are things intentionally done, but they do not seem to be suitably related to mental states. I suggest that once manifestations of habit are properly distinguished from exercises of skills and other kinds of spontaneous acts, we can see that habit raises a distinctive sort of problem. I examine certain responses that have (...) been given, as well as responses that could be given on behalf of the standard story to the problems presented by habitual activity. These responses rely on the idea of a kind of intention that does not ensue from conscious thought or deliberation. I raise three different objections to this line of response. The conclusion is that habit explains aspects of human behavior that cannot be accounted by ascribing intentions of any kind. (shrink)

Bill Pollard has recently developed an account of habits of action, endeavoring to rehabilitate the traditional notion of habit in a way that can be used to address current philosophical concerns. I argue that Pollard’s account has important shortcomings. The account is intended to apply indiscriminately to both habitual and skilled acts, but this overlooks crucial distinctions. Moreover, Pollard’s account fails to do justice to the various ways in which the idea of habit figures in the explanation and assessment of (...) action. These shortcomings are a consequence of certain assumptions Pollard shares with the accounts of mind and action he sets to criticize. As long as these assumptions are left intact, the potential of dispositional notions such as habit and skill to contribute to contemporary debates will not be realized. (shrink)

Patients living with chronic pain require appropriate access to opioid therapy along with improved access to pain care and additional therapeutic options. It's both medically reasonable and ethical to consider opioid therapy as a treatment option in the management of chronic, non-cancer pain for a subset of patients with severe pain that is unresponsive to other therapies, negatively impacts function or quality of life, and will likely outweigh the potential harms. This paper will examine opioid therapy in the setting of (...) the opioid epidemic, why critics feel that the CDC guideline has resulted in harsh consequences for patients and their physicians, and the rationale for opioid therapy as a means of providing ethical and compassionate pain care.
