Positive thinking is often assumed to foster effort and success. Research has shown, however, that positive thinking in the form of fantasies about achieving an idealised future predicts less (not...

Nowadays creativity is fashionable. Writers on management and organisation, for example, mention creativity as vital to entrepreneurship.1 They consider it to be as important as land, labour and capital, which form the traditional factors of production.2 And related terms such as ‘genius’ are in use again. An example of this is the widely read book Built to Last.3 Moreover, creativity and rationality are presented as alternatives. To be creative, managers are urged to put rationality aside: ‘being reasonable does not win (...) the day’ they are assured4 and ‘all progress depends on the unreasonable man’.5 This view that rationality and creativity oppose each other is, however, unsatisfactory involving, as it does, a form of epistemological schizophrenia. One excludes the other only if we adopt a simplistic concept of rationality and an esoteric view of creativity. This article, therefore, sets out to clarify the relationship between the concepts of creativity and rationality. Three ideal-type concepts of rationality will be introduced (algorithmic, judgemental, reflective) and their tolerance of novelty discussed. Then two modes of creativity (explorative and transcendentive) are distinguished, followed by a discussion of whether rationality can enhance creativity. I conclude by reviewing some factors involved in creativity, such as tolerance for ambiguity, playfulness and attentiveness, and with a short discussion of the relationship of creativity to power.6.

Although Taylor’s scientific management is often severely criticised, his publications are seldom the subject of scrutinised, philosophical, reading. The latter is the aim of the present text. Attention is given to the idea of science, the role of extra-scientific values, the relationship of theory and practice, the societal meaning of management, presenting demarcations, presuppositions and unclarities. The conclusion notes several topics, implied by Taylor’s views and still worth reflecting upon. One example is efficiency as a seemingly context-independent concept.

A beneficial effect of gesture on learning has been demonstrated in multiple domains, including mathematics, science, and foreign language vocabulary. However, because gesture is known to co‐vary with other non‐verbal behaviors, including eye gaze and prosody along with face, lip, and body movements, it is possible the beneficial effect of gesture is instead attributable to these other behaviors. We used a computer‐generated animated pedagogical agent to control both verbal and non‐verbal behavior. Children viewed lessons on mathematical equivalence in which an (...) avatar either gestured or did not gesture, while eye gaze, head position, and lip movements remained identical across gesture conditions. Children who observed the gesturing avatar learned more, and they solved problems more quickly. Moreover, those children who learned were more likely to transfer and generalize their knowledge. These findings provide converging evidence that gesture facilitates math learning, and they reveal the potential for using technology to study non‐verbal behavior in controlled experiments. (shrink)

Consciousness is targeted by both philosophers and neuroscientists; but different methodological premises and even different conceptions about what conscious experience is and how the challenges and potential problems associated with consciousness research should be formulated underlie the different approaches. Namely, whereas empirical data and the constant refinement of experimental procedures to expand and modify this body of empirical data and resulting empirical theories are crucial to neuroscience, the significance of empirical knowledge to philosophy is less clear: Although empirical data certainly (...) can influence philosophical concepts, the latter are nonetheless prerequisites of empirical research itself and thus may themselves not be empirically testable. The present paper elaborates from a multidisciplinary, neuroscientist-philosopher’s perspective the relation of philosophical concepts and empirical research on consciousness, drawing on two exemplary controversies from the philosophy of mind – on the ontological status of experiential properties and on free will. Consequences from both the scientific and the philosophical standpoint are discussed. (shrink)

A couple may have a child to provide stem cells for another child. They may also use preimplantation testing—even, troubling though it is, prenatal testing and selective abortion—to ensure a close tissue match.

Despite the growing debate about scholarly impact, an analysis of the onto-epistemic grammar underlying impact has remained absent. By taking a different analytical approach to examining impact, we interrogate the concept through the lens of decolonial thought. We offer an empathetic review of the impact scholarship and illuminate the limits of the modern imaginary that circumscribe critiques of impact in the literature, making visible the Eurocentric and provincial horizons of modern reason underlying these critiques and impact in general. Drawing on (...) Śūnyatā ontological perspective, we seek to articulate from modernity imaginary’s edges and suggest imagining and being otherwise. We argue that the question of scholarly impact is intimately structured by and connected to the modern subject’s desire for ontological security. (shrink)

Hardman and Hutchinson claim that ethics is ‘grounded in particular, everyday concerns’. According to them, an implication of this is that ethics courses for (future) clinicians should de-emphasise teaching the theories and principles of philosophical ethics and focus instead on pedagogical activities more closely related to everyday concerns, for example, exposure to real patient accounts. I respond that, even if ethics is an ‘everyday’ phenomenon, learning philosophical ethics may be of significant practical benefit to clinicians. I argue that the theories (...) of philosophical ethics can reasonably be interpreted as partial, simplified descriptions—or models—of moral phenomena, and that they can be effectively deployed in tandem by clinicians as complementary decision-making tools for help in navigating ethically complex situations in the clinic.

David Chalmers has distinguished the “hard” and the “easy” problem of consciousness, arguing that progress on the “easy problem”—on pinpointing the physical/neural correlates of consciousness—will not necessarily involve progress on the hard problem—on explaining why consciousness, in the first place, emerges from physical processing. Chalmers, however, was hopeful that refined theorizing would eventually yield philosophical progress. In particular, he argued that panpsychism might be a candidate account to solve the hard problem. Here, I provide a concise stock-take on both the (...) empirical-neuroscientific and philosophical-conceptual progress on consciousness. It turns out that, whereas empirical progress is indisputable, philosophical progress is much less pronounced. While Chalmers was right, I argue, in distinguishing distinctive types of problems of consciousness, his prediction of progress on the hard problem was overly optimistic. Empirical progress and philosophical progress are essentially uncoupled; a more skeptical perspective on progress in philosophy in general is appropriate. (shrink)

Chronic pain is a common disorder with enormous sociomedical importance. A major part of primary and secondary costs of illness is caused by the various pain syndromes. Nociception – the sensory perception of a painful stimulus – is a complex process relying on an intricate system of anatomical, neurophysiological and biochemical networks. This applies even more so to pain – the state of experiencing a nociceptive event, of interpreting it in terms of meaning for the affected individual and of suffering (...) a range of emotions it elicits. This intricacy renders it obvious, that the empirical medical sciences alone cannot explain all aspects of pain. Hence, it has also become a focus of phenomenological research. One aspect of these investigations is the interaction of pain and the perception of the lived body’s spatiality. The focus of this article will build on these concepts to develop a construct of the alteration of temporality caused by chronic pain and the effects this spells out for the affected subject. To this end, I will primarily draw on Merleau-Ponty’s ideas of the lived body as well as on theories of enactivism and embodiment. I will also point out parallels to neuroscientific data, thereby demonstrating the proximity of phenomenology and neuroscience. A possible partial solution to the pain dilemma may be derived from psychology: techniques relying on cognitive behavioural intervention, awareness training, and existential analysis may provide alleviation to patients suffering from chronic pain.

BackgroundThe outbreak of novel coronavirus disease 2019 has caused a global panic and public concern due to its mortality ratio and lack of treatments/vaccines. Reduced levels of physical activity have been reported during the outbreak, affecting the normal daily pattern.ObjectiveTo investigate the relationship of physical activity level with sleep quality and the effects of reduction physical activity levels on sleep quality.MethodsA Google form was used to address personal information, COVID-19 personal care, physical activity, and mental health of 1,907 adult volunteers. (...) Binary logistic regression was used to verify the association of physical activity parameters and sleep quality.ResultsInsufficient physical activity levels were a risk factor to have disturbed sleep pattern [OR: 1.28, 95% CI ]; however, when the BMI was added to the analysis, there was no more statistical difference [OR: 1.23, 95% CI ]. On the other hand, we found that the reduction of physical activity levels was associated with negative changes in sleep quality [OR: 1.73, 95% CI ], regardless all the confounders [OR: 1.30, 95% CI ], unless when feeling of depression was added in Model 6 [OR: 1.28, 95% CI ].ConclusionDisruption in daily physical activity routine, rather than physical activity level, negatively influences sleep quality during the COVID-19 quarantine.

The major stakeholder classes in education have three distinct ways by which they judge the quality of knowledge claims. At times this can cause considerable distraction or mis-communication among stakeholders.

Weights of evidence and logistic regression are two loglinear methods for mineral potential mapping. Both models are limited by their respective basic assumptions in application. Ideally, WofE indicator patterns have the property of conditional independence with respect to the point pattern of mineral deposits to be predicted; in LR, there supposedly are no interactions between the point pattern and two or more of the indicator patterns. If the CI assumption is satisfied, estimated LR coefficients become approximately equal to WofE contrasts (...) and the two methods produce similar results; additionally, bias then is avoided in that the sum of all estimated posterior probabilities becomes approximately equal to the number of observed discrete events. WofE allows construction of input layers that have missing data as a separate category in addition to known presence-absence type input, while logistic regression as such is not capable of handling missing data. As an improved WofE model based on LR, modified weights of evidence inherit the advantages of both LR and WofE, i.e., eliminates bias due to lack of CI and can handle missing data as well. Pixel or unit area input for MWofE consists of positive and negative weights for presence and absence of a pattern plus zeros for missing data. MWofE first is illustrated by application to simple examples. Next, it is applied to a study area with 20 known gold occurrences in southwestern Nova Scotia in relation to four input layers based on geological and lake geochemical data. Assuming that geochemical data were missing for the northern part of the study area, MWofE, like WofE but unlike LR, provides posterior probabilities for the entire area. (shrink)

This collection of articles and review essays, including many hard to find pieces, comprises the most important and fundamental studies of Indian logic and linguistics ever undertaken. Frits Staal is concerned with four basic questions: Are there universals of logic that transcend culture and time? Are there universals of language and linguistics? What is the nature of Indian logic? And what is the nature of Indian linguistics? By addressing these questions, Staal demonstrates that, contrary to the general assumption among (...) Western philosophers, the classical philosophers of India were rationalists, attentive to arguments. They were in this respect unlike contemporary Western thinkers inspired by existentialism or hermeneutics, and like the ancient Chinese, Greeks, and many medieval European schoolmen, only--as Staal says--more so. Universals establishes that Asia's contributions are not only compatible with what has been produced in the West, but a necessary ingredient and an essential component of any future human science.

Israel Scheffler's ground-breaking essay, On Human Potential, deserves to be more widely known among educational policy analysts, especially in light of the popularity in educationist circles of W.E. Deming's organizational philosophy known as Total Quality Management . In what follows,I argue that the heuristical value of Deming's perscriptions are entailed in Scheffler's On Human Potential. More importantly, I argue, where Deming's work falls short, especially in being naive about the human condition, Scheffler's analysis provides a foundation for management theory in (...) education that insures the flourishing of an optimal number of contributing participants. In fashioning these ideas, Scheffler brings pioneering thinking to the emerging fields of management studies generally and educational policy specifically. (shrink)

Until less than a century ago, the two prevailing views of dreams as well as of souls were that they are inconsequential or of divine origin. In either case it was assumed that they cannot be objects of rational inquiry. Similar views still prevail regarding mystical experiences and mysticism in general. Modern Western opinion, whether friendly or hostile, holds that the mystical falls squarely within the domain of the irrational. Mr. Staal argues that mysticism can be studied rationally, and that (...) without such study no theory of mind is complete. He exposes the grounds for the belief that mysticism cannot be studied, and shows them to be prejudices issuing from a particular historical development. While his contention has unflattering implications for the contemporary study of the humanities in general, it reveals in particular that existing academic approaches to the study of mysticism, even those that appear sound, are in fact inadequate. This conclusion applies to a variety of dogmatic inquiries and, as becomes clear in these pages, to philological, historical, phenomenological, sociological, physiological, and psychological ones as well. The illustrations in _Exploring Mysticism_ are drawn mainly from Indian forms of mysticism such as Yoga, supplemented with Buddhist, Taoist, Muslim and Christian examples. (shrink)

This paper examines Hume’s understanding of a third doxastic position distinct from belief and disbelief, arguing that his epistemology presupposes different forms of doxastic neutrality. While Hume does not explicitly discuss this third position, his Treatise of Human Nature and Enquiry concerning Human Understanding offer ideas relevant to contemporary debates on suspension of judgement and inquiry. Hume engaged with Pyrrhonian scepticism, finding its suspension of judgement excessive, yet acknowledging that the Pyrrhonian arguments are theoretically difficult to refute. Based on various (...) interpretations of Hume’s critique of Pyrrhonian ideas, we discuss the relevance of his thoughts on suspension of judgement and inquiry through the lens of modern epistemological discussions.

Matthew Lipman befriended me at an APA meeting in 1974. Through more than twenty years of phone calls, I got to chat with, consult with, and learn from Matt the details and challenges of developing philosophy for children. He acknowledged that I convinced him that the program needed “branding,” lest anyone present similar-sounding programs—some of which might be good and others not. He got a snippet of a video of my teaching troubled sixth-graders with his book Harry Stottlemeier’s Discovery on (...) the Today Show with Bryant Gumbel. That did much to shape my future, as did branding for sustaining Matt’s program. Lipman and I spoke by phone several times every year from 1976 until the mid-1990s. (shrink)

Taking his critique of totalitarianizing conceptions of community as a starting point, this text examines Jean-Luc Nancy's work of an ‘ontology of plural singular being’ for its political implications. It argues that while at first this ontology seems to advocate a negative or an anti-politics only, it can also be read as a ‘theory of communicative praxis’ that suggests a certain ethos – in the form of a certain use of symbols (which is expressed only inaptly by the word ‘style’) (...) that would render the ontological plurality of singulars perceptible and practically effective. Finally, some recent texts by Nancy even sidestep the ontology of being-with and face the question of what politics, faced with demands of justice, could be and what a democratic politics could provide. Both of these aspects in Nancy's work, however, still remain to be spelled out more politically. (shrink)

Thirty-four contributors address a variety of topics, from ancestral worship to transsexual masquerades, from metrical verse in the psalms to temples, poetic expression and linguistic performances. They bespeak the unique characteristics of Staal and his ability to break down barriers between academic disciplines. With contributors from around the world, this is a tribute to the forty years of scholarly work Frits Staal has invested in the foundation of a genuinely human science.

While the words “utopia” and “anticipation” frequently appear together in discussions of the concepts of utopia and dystopia, little attention to the relationship of Anticipation Studies to utopian studies exists. Moreover, the relevance of literature and the arts to Anticipation Studies seems almost invisible. This essay focuses on the structuring of the original utopian narrative, Sir Thomas More’s Utopia, in order to understand how this seminal text conceptualizes utopia’s relation to past, present, and future. This analysis focuses on the complex (...) framing devices characteristic of utopian narrative, as well as its open-endedness. The embedding of narratives sets up the dynamic movement between past, present, and future – the various forms of temporality – that allows us to clarify the nature of utopian anticipation.Throughout the chapter, I attempt to connect utopian textual and conceptual theory to specific concepts in the emerging field of Anticipation Studies, with which Utopian Studies, a long-established interdisciplinary field, have not yet engaged. Of particular interest is the notion, promoted by Miguel Abensour, that utopia is always a disruption and thus not an anticipation in any “natural” or logical sense: “what matters is the orientation toward what is different, the wish for the advent of a radical alterity here and now” : 407, 2008). From this premise, we can reintroduce a neglected literary term from science fiction theorist, Darko Suvin: the novum. The eruption of a future from a point of radical alterity – an ontological accident – opens up radical implication for the nature of utopian anticipation and futurity.Finally the essay suggests that Robert Poli’s and Robert Rosen’s description of an anticipatory system as comprising “the predictive model of itself” within the genre’s formal characteristics is in fact present in the structure of the utopian narratives: that is, that the persistence of utopia – as a literary genre and as a political concept – inheres in the narratological structuring of the possibility of another story and another listener. Utopian narrative thus ultimately anticipates not only temporal relationality, but an ethical relation between the outside narrator, the utopian traveler/narrator, and the reader. It anticipates another story. (shrink)

The theorizing of utopia is a persistent theme throughout several generations of the French continental tradition, and alongside the process theory of Alfred North Whitehead to a large degree recuperates the concept of utopia from its supposed dismissal by Marx and his intellectual descendants. Most recently, attention to the notion of plasticity, popularized by Catherine Malabou, extends speculation on utopian possibility. Compelled to answer to Marx’s denigration of utopia as fantasy, the tendency was to compensate for the absence of a (...) programmatic politics by stressing what is “useful” about utopian dreaming, and therefore where or how exactly a utopian text reveals or creates political drive, or motivates political action. In this essay, I argue that theorists have overlooked the use of utopia as not only the reproduction of difference, or what Malabou calls positive plasticity, but also as, therefore, a disruption; Malabou might prefer the term accident here. Tracing the concept of plasticity from Roland Barthes to Malabou, with a nod at Miguel Abensour, this essay teases out the links between a contemporary notion of plasticity to argue, simply put, that utopia is plastic. This plasticity of the concept ensures its political force. These links, obscured in the essay “Plastic,” Barthes makes only later in his writing. But for Malabou, plasticity underlies a principle of futurity and/as generativity, such that new forms, new meanings, new concepts emerge through difference. Utopia’s horizons of potentiality depend on difference, and on non-achievement. Finally, I argue that the persistence of utopia as a form of thinking is the most important, and political, effect of utopian plasticity. (shrink)

This paper warns against destructive effects of subjectivist thinking. Subjectivist accounts, as Alan Sokal exposed, promote a distorted view of scientific practice. For example, Einstein's 1905 special theory of relativity relied on data produced by Fizeau, a physicist trained in classical mechanics. Einstein's use of Fizeau's results shows that the ontological foundation of uncontroversial data transcends conventional speculations. Einstein's employment of Fizeau's results mitigates against ideas such as paradigm shifts and revolutionary science. Instead, the ontology of shared horizons of fact (...) remains largely unadulterated. The descriptions scientists use accommodate received view shifts, but the horizon of fact remains unimpeachably the same. The apt performance of science shows what it means to move further away from error. The only direction away from error is toward truth. To deny the reality of this directionality flies in the face of common sense and prudent science. (shrink)
