In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Pragmatism's Evolution: Organism and Environment in American Philosophy by Trevor PearceAlexander KleinTrevor Pearce. Pragmatism's Evolution: Organism and Environment in American Philosophy. Chicago: The University of Chicago Press, 2020. Pp. 384. Paperback, $35.00.Pragmatist pioneers were young lions in the days of Darwin. Evolutionary-biological thinking infused this philosophical movement from the start. And yet the last time a major monograph appeared on classic pragmatism and evolutionary biology—Philip Wiener's Evolution and (...) the Founders of Pragmatism (New York: Harper Torchbooks, 1949)—the author could personally thank Ralph Barton Perry, William James's junior colleague and eventual biographer. John Dewey himself wrote the foreword.Almost seventy-five years later, we have Trevor Pearce's painstakingly researched Pragmatism's Evolution. The author has graduate training in both biology and philosophy and is a former student of William Wimsatt and Robert Richards's (343). The book offers an intricate portrait of how debates about evolutionary biology informed the thinking of a loose-knit group of pragmatists between the years 1860 and 1910. While a remarkable variety of figures are discussed, ten pragmatists command the most attention: Chauncey Wright, C. S. Peirce, Francis Ellingwood Abbot, John Fiske, William James, Josiah Royce, John Dewey, Jane Addams, G. H. Mead, and W. E. B. Du Bois (18). Call them "the American Ten."Without downplaying Darwin, an overarching theme is the special significance of Herbert Spencer. Despite many specific disagreements with him (see e.g. 74, 207–8, 253–54, 281), the American Ten all accepted something more fundamental from Spencer: an intellectual framework that explains mind and morality in terms of functional relationships between organism and environment.After an introduction outlining what Pearce identifies as four chronological "cohorts" of pragmatists (more on this concept below), he examines the 1860s and 1870s reception of Darwin (chapter 1) and Spencer (chapter 2), showing how senior pragmatists like Wright, Peirce, and James defended evolution during this period. In chapter 2, we meet the Metaphysical Club's arch Spencerian, John Fiske, and we get a reading of James's critique of Spencer's psychology and sociology. Chapter 3 gives a highly detailed, reference-work-like portrait of the second cohort's training in evolutionary biology during the 1880s—chiefly Royce, Dewey, Addams, Mead, and Du Bois. In chapter 4, we learn that in the 1880s and 1890s, idealists like Edward Caird, Samuel Alexander, David George Ritchie, and Josiah Royce all co-opted ideas from evolutionary biology, which they apparently thought compatible with Hegelian dialectics. Chapter 5 shows that central planks of Peirce's metaphysics and Dewey's ethics are responsive to an 1890s dispute over the causes of the biological variation upon which selection acts (the so-called "factors" debate). The final two chapters show how pragmatist ethics (chapter 6) and epistemology (chapter 7) were infused with substantive ideas about evolution and about scientific experiment more generally.The depth and use of historical scholarship on offer here are both remarkable. On depth, Pearce draws from nineteen special collections and archives housed at institutions from California to Manchester, UK. The reference list (published on Pearce's website) runs [End Page 160] to 118 pages and was apparently too long for inclusion in the book. Archival research and lengthy bibliographies are to be expected in today's history of philosophy. But the sheer range of sources Pearce draws from is, by any measure, impressive.The use to which he puts those sources is provocative. Close reading, and in particular argument reconstruction, is usually the stock in trade for historians of philosophy. Pearce takes a different approach (7), seeking interpretive insight through a kind of philosophical network analysis. The nodes are mainly philosophers, scientists, and social critics. Unlike digital network analyses, Pearce connects his nodes by hand, via a great multiplicity of social, educational, and intellectual relations. We learn who studied evolution where, with whom, and when; what specific texts were assigned in classes taken, in classes taught; who attacked whom, who sided with whom; and so on.The resulting networks are rich, though they can be difficult to track due to their complexity. At its best, the book uses networks to produce genuine insights that... (shrink)

Who is God? If we want to love God, to serve God, and to make God the center of our lives, we would do well to settle this question at least in some small way. Yes, we can never know everything about God, and yes, the Christian life is about coming to know God more and more. However, this book serves as a starting point for understanding what Christians mean when they say "God," and to whom they are referring when (...) they use this name. Part of the What Every Catholic Should Know series, God: What Every Catholic Should Know is born out of the recognition that God is central to the Faith, but we encounter misconceptions about God all the time. In an effort to clear up these misconceptions, this book addresses three major concepts-the nature of God, the Trinity, and the Incarnation-so that we may strengthen our faith and our ability to communicate it to other people. Some of us might protest that we are not smart enough to do theology and that less is more when it comes to contemplating the divine. We might even think that too much theology detracts from simple faith. But if God is perfect, wonderful, all goodness, love itself-as the Bible tells us in 1 John 4:8-it would be strange indeed if we did not want to give our whole selves to God, including our minds. After all, the Lord himself tells us: "you shall love the Lord with all your heart and with all your soul and with all your mind and with all your strength" (Mark 12:30). Book jacket. (shrink)

The party registration of tenure‐track faculty at 11 California universities, ranging from small, private, religiously affiliated institutions to large, public, elite schools, shows that the “one‐party campus” conjecture does not extend to all institutions or all departments. At one end of the scale, U.C. Berkeley has an adjusted Democrat:Republican ratio of almost 9:1, while Pepperdine University has a ratio of nearly 1:1. Academic field also makes a tremendous difference, with the humanities averaging a 10:1 D:R ratio and business schools averaging (...) 1.3:1, and with departments ranging from sociology (44:1) to management (1.5:1). Across all departments and institutions, the D:R ratio is 5:1, while in the “soft” liberal‐arts fields, the ratio is higher than 8:1. These findings are generally in line with comparable previous studies. (shrink)

I suggest that the recent, highly visible, and often heated debate over failures to replicate the results in the social sciences reveals more than the need for greater attention to the pragmatics and value of empirical falsification. It also is a symptom of a serious issue -- the underdeveloped state of theory in many areas of psychology. While I focus on the phenomenon of “social priming” -- since it figures centrally in current debate -- it is not the only area (...) of psychological inquiry to which my critique applies. I first discuss some of the key issues in the “social priming” debate and then attempt to show that many of the problems thus far identified are traceable to a lack of specificity of theory. Finally, I hint at the possibility that adherence to the materialist tenets of modern psychological theory may have a limiting effect on our full appreciation of the phenomena under scrutiny.

The third Earl of Shaftesbury was a pivotal figure in eighteenth-century thought and culture. Professor Klein 's study is the first to examine the extensive Shaftesbury manuscripts and offer an interpretation of his diverse writings as an attempt to comprehend contemporary society and politics and, in particular, to offer a legitimation for the new Whig political order established after 1688. As the focus of Shaftesbury's thinking was the idea of politeness, this study involves the first serious examination of (...) the importance of the idea of politeness in the eighteenth century for thinking about society and culture and organising cultural practices. Through politeness, Shaftesbury conceptualised a new kind of public and critical culture for Britain and Europe, and greatly influenced the philosophical and cultural models associated with the European Enlightenment.

This study probes whether a prosopagnosic patient can make accurate explicit affective judgements towards faces. Patient MJH was shown photographs of faces of well-liked family members and public figures rated as “evil” by opinion polls. MJH was asked to rate each face on two 7-point scales (Likeability and Pleasantness). Since he is unable to explicitly recognise faces, his ratings were based on his evaluative reaction to the faces presented. In a second phase of the experiment, MJH was told the name (...) of the faces previously presented and asked to rate them using the same scales. MJH's Likeability ratings during the picture-viewing phase of the experiment and the explicit phase were highly correlated. Based on these findings, we propose that thought consists of an explicit declarative and an implicit emotional aspect, which may become dissociated in prosopagnosia. (shrink)

A central theme of Cheryl Misak’s important new history is that there are two markedly different strands of the pragmatist tradition. One pragmatism traces back to Peirce, she thinks, and it takes seriously the ideals of logical precision, truth, and objectivity. This tradition had its insights carried through later analytic philosophy by figures like C. I. Lewis, Quine, and Davidson, among others. The second pragmatism has its roots in James’s (allegedly) more subjectivistic outlook and after Dewey’s death was revived by (...) Goodman, Rorty, and other so-called “neo-pragmatists.”Misak recommends the Peircean strain because it is “committed to doing justice to the objective dimension of human inquiry” (Misak 2013: 3)...

Summary From summer 1792 until spring 1797, Alexander von Humboldt was a mining official in the Franconian parts of Prussia. He visited mines, inspected smelting works, calculated budgets, wrote official reports, founded a mining school, performed technological experiments, and invented a miners’ lamp and respirator. At the same time he also participated in the Republic of Letters, corresponded with savants in all Europe, and was a member of the Leopoldine Carolinian Academy and the Berlin Gesellschaft Naturforschender Freunde. He collected minerals, (...) made geognostic observations, performed chemical and physiological experiments, read the newest scientific journals, and prepared and published texts on mineralogy, geognosy, chemistry, botany and physiology. Humboldt did his scientific investigations alongside his administrative and technical work. This raises the question of whether there were fruitful interactions between Humboldt's technical-administrative work and (parts of) his natural inquiry. I argue that the mining official Humboldt was a late eighteenth-century figure of hybrid savant-technician. Mines and smelting works provided numerous opportunities for studies of nature. Humboldt systematically used inspection tours for mineralogical and geognostic observations. He transformed mines into chemical laboratories, and he transferred knowledge and material items from his natural inquiries in mines to academic institutions. The main objective of this paper is to illuminate the persona of savant-technician (or scientific-technological expert) along with Humboldt's mixed technological and scientific work during his term as mining official.

BackgroundAn increasing number of studies utilize intracranial electrophysiology in human subjects to advance basic neuroscience knowledge. However, the use of neurosurgical patients as human research subjects raises important ethical considerations, particularly regarding informed consent and undue influence, as well as subjects’ motivations for participation. Yet a thorough empirical examination of these issues in a participant population has been lacking. The present study therefore aimed to empirically investigate ethical concerns regarding informed consent and voluntariness in Parkinson’s disease patients undergoing deep brain (...) stimulator (DBS) placement who participated in an intraoperative neuroscience study.MethodsTwo semi-structured 30-minute interviews were conducted preoperatively and postoperatively via telephone. Interviews assessed participants’ motivations for participation in the parent intraoperative study, recall of information presented during the informed consent process, and participants’ postoperative reflections on the research study.ResultsTwenty-two participants (mean age = 60.9) completed preoperative interviews at a mean of 7.8 days following informed consent and a mean of 5.2 days prior to DBS surgery. Twenty participants completed postoperative interviews at a mean of 5 weeks following surgery. All participants cited altruism or advancing medical science as “very important” or “important” in their decision to participate in the study. Only 22.7% (n = 5) correctly recalled one of the two risks of the study. Correct recall of other aspects of the informed consent was poor (36.4% for study purpose; 50.0% for study protocol; 36.4% for study benefits). All correctly understood that the study would not confer a direct therapeutic benefit to them.ConclusionEven though research coordinators were properly trained and the informed consent was administered according to protocol, participants demonstrated poor retention of study information. While intraoperative studies that aim to advance neuroscience knowledge represent a unique opportunity to gain fundamental scientific knowledge, improved standards for the informed consent process can help facilitate their ethical implementation.

A common refrain in and outside academia is that prominent sports figures ought to engage more in the public discourse about political issues. This idea parallels the idea that athletes ought to be role models in general. This paper first examines and critiques the “athlete as role model” argument and then applies this critique to the “athlete as political activist” argument. Appealing to the empirical political psychological literature, the paper sketches an argument that athlete activism might actually do more harm (...) than good. (shrink)

The turn of the last century saw an explosion of philosophical realisms, both in the United States and in the United Kingdom. Gary Hatfield helpfully asks whether we can impose order on this chaotic scene by portraying these diverse actors as responding to a common philosophical problem—the so-called problem of the external world, as articulated by William Hamilton. I argue that we should not place the American realism that grows out of James’s neutral monism in this problem space. James first (...) articulated his position in response to critical attacks on the methodology he had employed in his psychological research. The direct topic of these criticisms was James’s earlier claim that a scientific psychology must treat knowledge as an inexplicable theoretical primitive. If I am right, then we ought to hesitate about Hatfield’s suggestion that American realism operated inside the same problem space as the early realism of British figures like Russell and Moore. James’s neutral monism first emerged as a conception of knowledge by a psychologist, and it was designed to meet concerns about his scientific research that had been raised by other psychologists.

The concept of empiricism evokes both a historical tradition and a set of philosophical theses. The theses are usually understood to have been developed by Locke, Berkeley, and Hume. But these figures did not use the term “empiricism,” and they did not see themselves as united by a shared epistemology into one school of thought. My dissertation analyzes the debate that elevated the concept of empiricism (and of an empiricist tradition) to prominence in English-language philosophy. -/- In the 1870s and (...) ’80s a lively debate about psychology emerged. Neo-Kantian idealists criticized the very idea that the mind can be studied scientifically. A group of philosopher-psychologists responded, often in Mind. They were among the first to call themselves “empiricists,” arguing that psychology could provide a scientific basis for philosophical progress. Idealists held that empirical psychology depended on premises developed by Locke, Berkeley, and Hume. These premises were allegedly absurd because they rendered ideas of extension, as well as other ideas crucial to natural science, unreal. Those who wanted to advance psychology towards becoming a legitimate science were forced to engage these philosophical attacks, while at the same time to develop empirical theories that could successfully explain some characteristics of experience. I show how James’s theory of space perception accomplished both tasks. -/- In developing this theory, James found he had to reject the Lockean notion that reality is associated with passively-registered sensations. James also abandoned Berkeley and Hume’s claim that ideas are ultimately derived from atomic sensations. Instead, James presented experimental evidence that sensation is a continuous stream. The mind must actively parse this stream if it is to gain a coherent representation of its environment. I argue that James’s stream-of-thought thesis served as a presupposition of his entire psychology. The thesis showed how the labor of investigating the mind could be divided between philosophers and scientists, and in a manner sensitive to the concerns of both. The stream thesis also provided a scientific basis for a new philosophical empiricism that, I argue, has a hidden legacy in the history of analytic philosophy. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:From Children's Perspectives:A Model of Aesthetic Processing in TheatreJeanne Klein (bio)Since the children's theatre movement began, producers have sought to create artistic theatre experiences that best correspond to the adult-constructed aesthetic "needs" of young audiences by categorizing common differences according to age groups. For decades, directors simply chose plays on the basis of dramatic genres (e.g., fairy tales), as defined by children's presupposed interests or "tastes," by subscribing (...) to Winifred Ward's broad descriptions of the "imaginative period" (ages six to nine), the "heroic period" (ages nine to twelve), and the "romantic period" (over age thirteen).1 Years later, Moses Goldberg elaborated upon these generalized divisions while cautioning that "no individual fits exactly into any set of categories."2 In his position paper on aesthetic development, he argued for individual access to aesthetic techniques, processes, and products for all ages, paralleled by four stages of cognitive capabilities, based on exposure to (1) arena-style participation theatre (for ages five to eight), which emphasizes story enactments; (2) a wide range of proscenium-style theatrical conventions; (3) relevant play content that directly relates characters' problems to spectators' lives and growing self-awareness; and (4) social issue plays that pose ethical dilemmas as cultural reflections.3 Meanwhile, Jed Davis compiled Age Group Profiles, organized by cognitive, spatial, emotional, and moral/ethical development, from his review of Piagetian literature; and Johnny Saldaña summarized stages of young interpretations of theatre from his seven-year longitudinal study.4Suffice it to say, the field of developmental psychology has come a long way since Piaget formulated his four constructivist stages. Since the mid-1950s, the cognitive revolution has spurred more integrated theories of information processing and depth-of-processing models that explain and predict how people construct schematic frameworks of knowledge and [End Page 40] assimilate and accommodate new information as a function of perception, attention, emotion, comprehension, memory, and social and moral behaviors. Although masculinist metaphors of hierarchical "staircases" and linear networks of associative learning still dominate computational models, feminist perspectives, which engender social cognitive, co-relational negotiations of narratives in situated contexts, have gained more widespread acceptance—by including theatre as an apt metaphor for development.5 Over the past twenty years or more, cognitive psychologists have finally discovered what dramatic theorists have known about narrative structures since Aristotle's Poetics: Powerful stories contain universal themes about the human condition through characters' conflicting actions. The most successful dramas are those that allow spectators to enter into a protagonist's psychological consciousness or "inner" vision in order to empathize with her "outer" reality.6While several developmental models of aesthetic understanding, experience, and appreciation exist in the realms of visual art and music education, few examples have been proposed in regard to theatre, particularly for child audiences.7 Instead, producers of Theatre for Young Audiences (TYA) tend to romanticize its social and moral "effects" upon youth by believing passionately that viewing one remarkable performance has the potential (the operative word) to "cause" positive, social changes in children's minds, hearts, and behaviors, given the presumed "power of human imagination."8 This obsession with progressive change foregrounds adults' desires to control human destiny by predicting "causes and effects" located in children's responses to live performances. However, this "folk theory" fails to explain how young imaginations actually function aesthetically from the contextual evidence of reception studies with child audiences. Just as feminists have argued for a distinctive "feminist aesthetics," based on women's alternative ways of knowing,9 I argue that children gaze upon theatre in differential ways by including age as a variable factor. "Children's aesthetics," their perceived interpretations of theatre, differ from that of adults' theorized postulations, based in part on their shorter life experiences with this medium. To this end, over the course of my career, I have sought to understand theatre from children's perspectives by focusing my research in the social cognitive theories and social science methods of child development, primarily through the vast literature of television and mass media studies conducted with young people over the past forty years. In particular, medium-specific studies that parse theatrical forms from dramatic content... (shrink)

A conclusion drawn after a conference devoted (in 1995) to the “arrow of time” was the following: “Indeed, it seems not a very great exaggeration to say that the main problem with “the problem of the direction of time” is to figure out exactly what the problem is supposed to be !” What does that mean? That more than 130 years after the work of Ludwig Boltzmann on the interpretation of irreversibility of physical phenomena, and that one century after (...) Einstein’s formulation of Special Relativity, we are still not sure what we mean when we talk of “time” or “arrow of time”. We shall try to show that one source of this difficulty is our tendency to confuse, at least verbally, time and becoming, i.e. the course of time and the arrow of time, two concepts that the formalisms of modern physics are careful to distinguish.

This essay is conceived as a critical exposition of the central issues that figure in the ongoing conversation between Logical Positivists and neo Positivists on the one hand and Christian apologists on the other. My expository aim is to isolate and to describe the main issues that have emer ged in the extended discussion between men of Positivistic turn of mind and men sympathetic to the claims of Christianity. My critical aim is to select typical, influential stands that have (...) been taken on each of these issues, to assess their viability, and to isolate certain dilemmas which discussion of these issues has generated. I am convinced that the now commonly rejected verifiability theory of meaning is very commonly misunderstood and has been rejected by and large for the wrong reasons. Before it is cast off-if it is to be cast off-what is needed is a reconsideration of that theory and of the objections that its several formulations have elicited. Furthermore, at least partially because of a misconstruing of the verifiability doctrine, there have been some interesting-though in my opinion unsuccessful-claims advanced about the testability-status of sentences expressive of Christian belief. Moreover, in their haste to vindicate Christianity, some apologists have been fairly cavalier, in my opinion, about what "Christianity" involves. This volume offers what I hope will be a clear statement and analysis of the principle points at issue between Positivism and Christianity, together with my own assessment of where the argument stands now.

The patient empowerment process that took place in France during the 20th century can, artificially, be divided into three major periods, marked by the principles of solidarity, agency, and authority. This tripartition makes it possible to better understand the challenges of this movement and to see how the advent of health democracy, which took place at the beginning of the 21st century, led, through its depoliticization of autonomy issues, to the dismissal of patients towards a form of subalternity. Paradoxically, the (...) new figures of the patient, the expert, or the partner bear witness to this subalternity. (shrink)

OVERVIEWWe ambitiously reexamine Smith’s moral theory in relation to Hume’s. We regard Smith's developments as glorious and important. We also see them as quite fully agreeable to Hume, as enhancement, not departure. But Smith represents matters otherwise! Why would Smith overstate disagreement with his best friend?One aspect of Smith’s enhancement, an aspect he makes very conspicuous, is that between moral approval and beneficialness there is another phase, namely, the moral judge's sense of propriety. With that phase now finding formulation, Smith, (...) if only implicitly, generates a spiral of beneficialness and propriety, a spiral shown in Figure 7 in the present paper. We consider Figure 7, illustrating the spiral, to be the most important arrival point in the present paper; it highlights the non-foundationalism of Smith's ethics. But to arrive at the spiral, we must engage in extensive exegesis.In Part IV of The Theory of Moral Sentiments, Smith presents a foil against which he develops his own theory, a foil supposedly representing Hume. According to the foil, moral approval derives from ‘utility.’ But, in multiple ways, the foil is misleading. We provide an interpretation of Hume, notably his four-factor account of moral approval, before examining Smith's representation of Hume.One twist is that Smith used the words utility and useful differently than Hume did – Smith quietly stretched them to include species of agreeableness, thereby obscuring the importance of agreeableness in Hume’s theory.Another, more significant problem is that Smith allows the impression that in Hume moral approval derives quite determinately from beneficialness. In fact Hume conveys the interpretive and sentimental spaciousness of the operations that generate moral approval; here, Hume even speaks repeatedly of ‘proper sentiments’, thus almost using the term propriety himself.But the propriety phase in Smith opens up to a key facet of Smith’s development on Hume: He poeticizes a locus of sympathy not emphasized in Hume – namely, that between the moral judge and her own man within the breast; that locus enters the theory in addition to the sympathies emphasized in Hume, not in lieu of them. We distinguish lateral sympathy, which is important in Hume’s thought, and vertical sympathy, which is especially characteristic of Smith’s more inner-directed and allegorical thought. Smith embraces Hume’s lateral sympathy and enhances moral theory by adding formulations that elaborate vertical sympathy.Next, we come to something of a twist in the whole matter: We show that – as Smith well knew all along! – propriety is a species of agreeableness! Smith’s propriety phase represents another dimension within which such agreeableness lives: Smith’s vertical dimension thus gives rise to a spiral representing the diachronic development of the judge herself. It is a spiral of beneficialness and propriety: Each propriety phase in the next loop of the spiral engenders a species of agreeableness now as a part of beneficialness.Smith's developments on Hume, then, involve the following three facets: formulation of the propriety phase; the poetic elaboration of vertical sympathy; the diachronic spiral of propriety and beneficialness.The three facets come together, especially in Ed. 6 of The Theory of Moral Sentiments. The whole development goes beyond Hume, but, really, is agreeable to Hume – though Smith himself portrays his developments as disagreeing with features of Hume's moral theory.We speculate that Smith was more or less aware of all that that we say, including the absense of any really substantive disagreement. Why, in that case, would Smith have proceeded as he did? We address that question at the end of the piece. Our speculations suggest a method in the madness. (shrink)

ObjectiveThe objective of this study was to validate the computerized Symbol Digit Modalities Test in a Swiss pediatric cohort, in comparing the Swiss sample to the Canadian norms. Secondly, we evaluated sex effects, age-effects, and test–retest reliability of the c-SDMT in comparison to values obtained for the paper and pencil version of the Symbol Digit Modalities Test.MethodsThis longitudinal observational study was conducted in a single-center setting at the University Children’s Hospital of Bern. Our cohort consisted of 86 children aged from (...) 8 to 16 years. The cohort included both healthy participants and patients hospitalized for a non-neurological disease. Forty eight participants were assessed during two testing sessions with the SDMT and the c-SDMT.ResultsTest–retest reliability was high in both tests. A reliable change index was calculated for the SDMT and the c-SDMT corrected for practice effects. While a significant age effect on information processing speed was observed, no such effect was found for sex. When data on the c-SDMT performance of the Swiss cohort was compared with that from a Canadian cohort, no significant difference was found for the mean time per trial in any age group. Norm values for age groups between 8 and 16 years in the Swiss cohort were established.ConclusionNorms for the c-SDMT between the Swiss and the Canadian cohort were comparable. The c-SDMT is a valid alternative to the SDMT. It is a feasible and easy to administer bedside tool due to high reliability and the lack of motor demands. (shrink)

The premise of this paper is that the goal of signifying Being central to ontological phenomenology has been tacitly subverted by the semiotic structure of conventional phenomenological writing. First it is demonstrated that the three components of the sign—sign-vehicle, object, and interpretant (C. S. Peirce)—bear an external relationship to each other when treated conventionally. This is linked to the abstractness of alphabetic language, which objectifies nature and splits subject and object. It is the subject-object divide that phenomenology must surmount if (...) it is to signify Being. To this end, we go beyond alphabetic convention and explore the use of iconic signs. Following the lead of Merleau-Ponty, the iconic expression of Being is seen as entailing paradox, and we are directed to the fields of visual geometry and topology, where we work with three paradoxical figures: the Necker cube, Moebius strip, and Klein bottle. While the Necker cube and Moebius prove to have their limitations in fully signifying Being, the Klein bottle, possessing an added dimension (made palpable via a stereogram), can embody Being more intimately, provided that it is approached in a radically non-classical way. The essay closes with the realization that the most concrete signification of Being must be a self-signification. Here the author removes his cloak of anonymity and makes his presence tangibly felt in the text. (shrink)

In this transdisciplinary article which stems from philosophical considerations (that depart from phenomenology—after Merleau-Ponty, Heidegger and Rosen—and Hegelian dialectics), we develop a conception based on topological (the Moebius surface and the Klein bottle) and geometrical considerations (based on torsion and non-orientability of manifolds), and multivalued logics which we develop into a unified world conception that surmounts the Cartesian cut and Aristotelian logic. The role of torsion appears in a self-referential construction of space and time, which will be further (...) related to the commutator of the True and False operators of matrix logic, still with a quantum superposed state related to a Moebius surface, and as the physical field at the basis of Spencer-Brown’s primitive distinction in the protologic of the calculus of distinction. In this setting, paradox, self-reference, depth, time and space, higher-order non-dual logic, perception, spin and a time operator, the Klein bottle, hypernumbers due to Musès which include non-trivial square roots of ±1 and in particular non-trivial nilpotents, quantum field operators, the transformation of cognition to spin for two-state quantum systems, are found to be keenly interwoven in a world conception compatible with the philosophical approach taken for basis of this article. The Klein bottle is found not only to be the topological in-formation for self-reference and paradox whose logical counterpart in the calculus of indications are the paradoxical imaginary time waves, but also a classical-quantum transformer (Hadamard’s gate in quantum computation) which is indispensable to be able to obtain a complete multivalued logical system, and still to generate the matrix extension of classical connective Boolean logic. We further find that the multivalued logic that stems from considering the paradoxical equation in the calculus of distinctions, and in particular, the imaginary solutions to this equation, generates the matrix logic which supersedes the classical logic of connectives and which has for particular subtheories fuzzy and quantum logics. Thus, from a primitive distinction in the vacuum plane and the axioms of the calculus of distinction, we can derive by incorporating paradox, the world conception succinctly described above.

Ventricular Fibrillation is responsible for a majority of sudden cardiac death, but little is known about how ventricular tachycardia (VT) degenerates into ventricular fibrillation. Several clinical studies focused only on preventing VT with a class III antiarrhythmic drug resulted in many deaths. Our simulations investigate the interactions between an antiarrhythmic drug likely to suppress a VT and a Figure 8 reentry. A parameter AAR is introduced to increase the action potential duration and therefore simulate various Class III drugs. Simulations (...) are ran under several conditions (phases of the reentry, values of AAR, durations). They show that a VT can be suppressed whatever the phase of the reentry but it strongly depends on the duration of the effect. It confirms that a drug which can suppress a reentry can also worsen it. It also shows a great variety of activation patterns and thus the complexity of antiarrhythmic drugs effects. Simulations also demonstrate that suppressing VT is an increasing function of AAR.

The book Hidden Harmony—The Connected Worlds of Physics and Art by J.R. Leibowitz is critically reviewed. The book is intended for a general audience and does not assume prior knowledge of physics or the arts.
