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)

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)

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 central argument against Ryle’s (The concept of mind, University of Chicago Press, Chicago, 1949) distinction between propositional and non propositional knowledge has relied on linguistic evidence. Stanley and Williamson (J Philos 98:411–444, 2001) have claimed that knowing-how ascriptions do not differ in any relevant syntactic or semantic respect from ascriptions of propositional knowledge, concluding thereby that knowing-how ascriptions attribute propositional knowledge, or a kind thereof. In this paper I examine the cross-linguistic basis of this argument. I focus on the (...) linguistic analysis of practical knowledge ascriptions in Modern Greek, although the issues raised are not restricted to one language. It is relatively straightforward to show that none of the three types of practical knowledge ascriptions in Modern Greek is an embedded question configuration, and hence Stanley and Williamson original claim is confined to certain languages only. This is not the end of the matter, however, since Stanley (Nous 45:207–238, 2011) argues that the equivalents of ‘knowing-how’ ascriptions in certain languages should be semantically analyzed as embedded questions despite their syntactic form. I argue that this fallback position faces a host of empirical and theoretical problems, in view of which it cannot bear the weight Stanley puts on it, supporting a conclusion about the kind of knowledge thereby attributed.

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)

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.

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.

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 →.

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.

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)

The thesis explores the semantics of epistemic justification discourse, a very important part of overall epistemic discourse. It embarks from a critical examination of referentialist theories to arrive at a certain nonreferential, expressivist approach to the semantics of epistemic justification discourse. That is, it criticizes the main referentialist theories and then goes on to argue for an expressivist approach on the basis of its theoretical capacity to outflank the problems referentialist theories meet. In the end, I also identify some problems (...) for a prominent expressivist theory and, as a response to these problems, propose a novel norm-expressivist approach that seems to evade these problems. In particular, in Ch.1 I introduce what I call ‘the epistemic justification puzzle’ and then in Chs.2-4 criticize naturalistic referential theories: analytic naturalistic reductionism, synthetic naturalistic reductionism and epistemic kinds realism. In Ch.5 I criticize nonnaturalist referential theories: what I call ‘naïve’ nonnaturalism and J.McDowell’s more sophisticated quietist version of nonnaturalism. Next, in Ch.6 I introduce the semantic programme of expressivism and go on to construct a simple version of epistemic norm-expressivism ) in order to explain how expressivism can easily outflank the identified problems of referentialist theories. This simple norm-expressivist theory, however, is only used as a theoretical ‘toy’ for the mere sake of motivating the possibility of expressivism, as in Ch.7 I go on to argue for a more sophisticated version of norm-expressivism: habitsendorsement expressivism. In Ch.7 I introduce a prominent expressivist theory of moral and knowledge discourses, namely, plan-reliance expressivism ) and extend it cover the epistemic justification discourse. I then identify some problems for plan-reliance expressivism as extended to cover justification discourse and in response to these problems propose habits-endorsement expressivism. Habits-endorsement expressivism builds on the intuition that belief-fixation is habitual and exploits the theoretical flexibility of the notion of habits in order to overcome the identified problems of plan-reliance expressivism.

While contemporary epistemologists consider Cartesian scepticism as a menacing problematic, it seems that Plato scarcely had any Cartesian doubts about knowledge of the extemal world. In this paper I ask why Plato had this cavalier attitude towards Cartesian scepticism. A quick first explanation is that Plato never conceived the challenge of Cartesian scepticism or at least, if he did, he missed the potential threat to empirical knowledge that such a challenge poses. I argue against this explanation and offer an altemative, (...) more plausible explanation.Very briefly, I claim that Plato grasped both the logical possibility of Cartesian scepticism and its potential threat but remained impervious because of his ontological epistemology. For Plato, the empirical world can hardly be an object of knowledge, just like a dream can hardly be an object of knowledge. But for Plato this is not really worrying because, necessarily, forms must exist and these constitute the truly real world and the tme object of knowledge. What is deeply worrying for Plato is that most people do not realize the 'dreaming' condition of the empirical world and need to be 'waken up' to the intelligible world of the forms by the philosophers-kings.

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)

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.

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)

In this study, I attempt to shed light on whether some passages from the Platonic dialogue Cratylus that deal with language correspond to Karl Popper’s theory on the third world. Specifically, I attempt to prove that Plato’s third world contains both divine and human properties, something that is provided through language, that is, through the human rational and developing in objective terms construction. In the four subchapters of my study, I basically investigate the relationship between the thinking subject and the (...) noumenon as well as the role of the coiner of names and the dialectician with respect to the scientific foundation of the names. The most important conclusion drawn is that according to Plato these two are responsible for connecting a thinking subject with a noumenon by adding objective certainty to the meaning of everything is said. I also investigate how Plato’s archetypal Ideas could be considered to be the third world. (shrink)

The Dutch Reformed Church had a strong missionary DNA since the planting of the church. This missionary focus and fervour, however, ebbed and flowed during the history of the church. Saayman described that the mission upsurges in the DRC in four waves or 'periods of extraordinary mission endeavour'. The current research aimed to develop this theory through a literature study on the sociopolitical context and the developments in the ecclesiology and missiology of the DRC since the planting of the church (...) up to 2013. The research found strong evidence to define a fifth wave. The fifth wave was influenced by contextual changes and loss of influence and money by the DRC. Furthermore, the growth in the church's missional identity can be seen in the following aspects: the influence of theologians like Lesslie Newbigin and David Bosch; a belief that mission is not something the church does but something the church is; a shift from a Christocentric theology to a Trinitarian theology; a holistic view of salvation; a commitment to the local context of the congregation and a focus on bringing healing to their local communities; and lastly, the success of the Gestuurde Gemeentes network and, more recently, the Mission Shaped Ministry training.

In order to make Aristotle’s philosophy better understood, I would like to provide here a brief but accurate account of the concepts of logos and nous, and their respective functions in his method of dialectic. Dialectic was used in all the major works of the corpus Aristotelicum, in the philosopher’s great effort to noetically grasp and philosophically explain the place of man in the cosmic order of things, and his search for eudaimonia. Since Aristotle’s conception of human nature and its (...) potential for virtuous activity, at the ethical and political or at the intellectual levels of excellence, has deeper roots in his ontology and ousiology, such a synoptic account will be useful, for it will provide an appropriate context for the correct evaluation of the ethical and political views of this philosopher. It will become clear from our analysis that he is misunderstood by scholars in the West and in the East for different historical reasons, which will be elucidated as we proceed further into the discussion of our theme in this essay.

The past two years have been eventful for Heidegger scholarship. Heidegger’s Black Notebooks from the 1930s were published (GA94–96), exposing his antisemitism in a new way, and reigniting several debates. The question that mattered most was whether his philosophy – rather than the person – was inherently antisemitic. If yes: should we continue reading and teaching Heidegger in the twenty-first century?

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.

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.

The domain of agential powers is marked by a contrast that does not arise in the case of dispositions of inanimate objects: the contrast between propensities or tendencies on the one hand, and capacities or abilities on the other. According to Ryle (1949), this contrast plays an important role in the ‘logical geography’ of the dispositional concepts used in the explanation and assessment of action. However, most subsequent philosophers use the terms of art ‘power’ or ‘disposition’ indiscriminately in formulating central (...) metaphysical claims about human agency, assuming that an adequate account of inanimate dispositions can safely be used for such purposes. As a result, the distinctive features of propensities and capacities drop out of view. This is bound to obscure distinctions of crucial importance to the understanding of human agency. In order to show this, I undertake to articulate some central differences between propensities and capacities. Propensities and capacities have a different relation to value, as well as a concomitant difference in their metaphysical structure. The argument points to an explanation of why the distinction between propensities and capacities does not arise in the case of non-agential powers. This explanation takes us back to questions about the nature of human agency. (shrink)

The article sets the most eminent defender of the French Revolution, Immanuel Kant, against its most eminent critic, Edmund Burke, articulating their radically different stance toward the French Revolution. Specifically, this juxtaposition is attempted through the concept of enthusiasm; a psychological state of intense excitement, which can refer to both actors and spectators, to both the motivation of someone, acquiring thus a practical significance, or to their distanced contemplation, thereby acquiring the character of aesthetic appreciation. Using the concept of enthusiasm, (...) Ι aspire to bring out Kant’s and Burke’s radically different approaches to society as well as its history and prospects of progress, ultimately suggesting that enthusiasm can provide a vantage point for the dialogue between the enlightenment and counter-enlightenment theses.

Most philosophers and psychologists assume that habitual acts do not ensue from deliberation, but are direct responses to the circumstances: habit essentially involves a variety of automaticity. My objective in this paper is to show that this view is unduly restrictive. A habit can explain an act in various ways. Pointing to the operation of automaticity is only one of them. I draw attention to the fact that acquired automaticity is one outgrowth of habituation that is relevant to explanation, but (...) not the only one. Habituation shapes our emotional and motivational make up in ways that affect deliberation itself. Hence mentioning a habit might be indispensable in explaining an act which nevertheless ensues from deliberation. The view that habitual acts are direct responses to the circumstances implies an impoverished conception of habit, which fails to do justice to its rich explanatory potential in theoretical and pre-theoretical contexts, as well as to its role in the history of philosophy.
