A brief history of Neutron Interferometry is presented, from a personal perspective. Comments and a message from Professor Sam Werner are included.

A argumentação desenvolvida no presente artigo se propõe a defender a interpretação austera do construtivismo em Kant das objeções a ela levantadas por Jeremy Schwartz (2017) em seu artigo _Was Kant a ‘Kantian Constructivist’?_. Tendo isso em vista, primeiramente, procede-se à reconstrução da interpretação de Schwartz para a distinção analítico-sintética na esfera prática a partir da caracterização por contradição e à indicação de objeções para sua aceitação. Na sequência, apresenta-se a caracterização de analiticidade por continência e como esta pode ser (...) transposta para o caso dos imperativos sem resultar em conflitos com a interpretação austera do construtivismo. Por fim, delineiam-se considerações quanto à formalidade dos princípios constitutivos da razão prática e seu escopo, chegando à conclusão de que não se pode estabelecer uma identidade entre construtivismo austero e logicismo prático.

This paper presents the results of optical interferometry experiments in which the phase of photons in one arm of a Mach-Zehnder interferometer is modified by applying a transverse constriction. An equivalent quantum interferometry experiment using neutron de Broglie waves is discussed in which the observed phase shift is in the spirit of the force-free phase shift of the Aharonov-Bohm effects. In the optical experiments the experimental results are in excellent agreement with predictions.

Cognitive Task Analysis (CTA) helps researchers understand how cognitive skills and strategies make it possible for people to act effectively and get things done. CTA can yield information people needemployers faced with personnel issues, market researchers who want to understand the thought processes of consumers, trainers and others who design instructional systems, health care professionals who want to apply lessons learned from errors and accidents, systems analysts developing user specifications, and many other professionals. CTA can show what makes the workplace (...) workand what keeps it from working as well as it might.Working Minds is a true handbook, offering a set of tools for doing CTA: methods for collecting data about cognitive processes and events, analyzing them, and communicating them effectively. It covers both the "why" and the "how" of CTA methods, providing examples, guidance, and stories from the authors' own experiences as CTA practitioners. Because effective use of CTA depends on some conceptual grounding in cognitive theory and researchon knowing what a cognitive perspective can offerthe book also offers an overview of current research on cognition.The book provides detailed guidance for planning and carrying out CTA, with chapters on capturing knowledge and capturing the way people reason. It discusses studying cognition in real-world settings and the challenges of rapidly changing technology. And it describes key issues in applying CTA findings in a variety of fields. Working Minds makes the methodology of CTA accessible and the skills involved attainable. (shrink)

Early versions of satellite and radiosonde datasets suggested that the tropical surface had warmed more than the troposphere, while climate models consistently showed tropospheric amplification of surface warming in response to human-caused increases in greenhouse gases. We revisit such comparisons here using new observational estimates of surface and tropospheric temperature changes. We find that there is no longer a serious discrepancy between modeled and observed trends in the tropics. Our results contradict a recent claim that all simulated temperature trends in (...) the tropical troposphere are inconsistent with observations. This claim was based on the use of older radiosonde and satellite datasets and on two methodological errors: the neglect of observational trend uncertainties introduced by interannual climate variability and application of an inappropriate statistical “consistency test”.This emerging reconciliation of models and observations has two primary explanations. First, because of changes in the treatment of buoy and satellite information, new surface temperature datasets yield slightly reduced tropical warming relative to earlier versions. Second, recently developed satellite and radiosonde datasets now show larger warming of the tropical lower troposphere. In the case of a new satellite dataset from remote sensing systems, enhancedRSS warming is due to an improved procedure of adjusting for inter-satellite biases. When the RSS-derived tropospheric temperature trend is compared with four different observed estimates of surface temperature change, the surface warming is invariably amplified in the tropical troposphere, consistent with model results. Even if we use data from a second satellite dataset with smaller tropospheric warming than in remote sensing systems RSS, observed tropical lapse rates are not significantly different from those in all model simulations.Our results contradict a recent claim that all simulated temperature trends in the tropical troposphere and in tropical lapse rates are inconsistent with observations. This claim was based on the use of older radiosonde and satellite datasets and on two methodological errors: the neglect of observational trend uncertainties introduced by interannual climate variability and application of an inappropriate statistical “consistency test”.

One of Israel Kirzner’s less wellknown contributions is to the theory of capital. In this paper, we link the Austrian theory of capital and the theory of economic organization. Our starting point is the key Austrian notion of capital heterogeneity which we interpret in terms of attributes. Most capital assets are multi-attribute in nature, and many attributes may not be known to entrepreneurs. This fosters a need for experimenting with capital combinations. Because there are costs of measuring attributes, this process (...) has implications for economic organization. Thus, we argue that novel implications for the understanding of ownership and the existence and boundaries of firms may be teased out of such a perspective.La théorie du capital représente une des contributions les moins connues d’Israel Kirzner. Dans cet article, nous établissons le lien entre la théorie autrichienne du capital et la théorie de l’organisation économique. Notre point de départ est la notion autrichienne fondamentale d’hétérogénéité du capital que nous interprétons en termes d’attributs. De par leur nature, la plupart des biens capitaux possèdent plusieurs attributs qui peuvent demeurer inconnus aux entrepreneurs. Ceci accroît la nécessité d’expérimenter des combinaisons capitalistiques. Etant donné les coûts qu’entraîne la mesure des attributs, ce processus a des implications quant à l’organisation économique. Ainsi, cette perspective permet de tirer de nouvelles implications pour notre compréhension de la propriété, de l’existence et de la taille des firmes. (shrink)

As the transaction cost theory of the firm was taking shape in the 1970s, another important movement in economics was emerging: a revival of the ‘Austrian’ tradition in economic theory associated with such economists as Ludwig von Mises and F. A. Hayek . As Oliver Williamson has pointed out, Austrian economics is among the diverse sources for transaction cost economics. In particular, Williamson frequently cites Hayek , particularly Hayek’s emphasis on adaptation as a key problem of economic organisation . Following (...) Williamson’s lead, a reference to Hayek’s ‘The Use of Knowledge in Society’ has become almost mandatory in discussions of economic organisation . However, there are many other potential links between Austrian and transaction cost economics that have not been explored closely and exploited.This article argues that characteristically Austrian ideas about property, entrepreneurship, economic calculation, tacit knowledge, and the temporal structure of capital have important implications for theories of economic organisation, transaction cost economics in particular. Austrian economists have not, however, devoted substantial attention to the theory of the firm, preferring to focus on business-cycle theory, welfare economics, political economy, comparative economic systems, and other areas. Until recently the theory of the firm was an almost completely neglected area in Austrian economics, but over the last decade, a small Austrian literature on the firm has emerged. While these works cover a wide variety of theoretical and applied topics, their authors share the view that Austrian insights have something to offer students of firm organisation. (shrink)

The 'Austrian' tradition is well-known for its definitive contributions to economics in the twentieth century. However, Austrian economics also offers an exciting research agenda outside the traditional boundaries of economics, especially in the management disciplines. This Element examines how Austrian ideas play a key role in expanding the understanding of fields like entrepreneurship, strategy, and organization. It focuses especially on the vital role that entrepreneurs play in guiding economic progress by shaping firms and their strategic behavior. In doing so, it (...) explains a wide range of contributions that Austrian economics makes to the understanding of key problems in management, while also highlighting many directions for future work in this inspiring tradition.

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.

What happens at the end of a clinical trial for an investigational neural implant? It may be surprising to learn how difficult it is to answer this question. While new trials are initiated with increasing regularity, relatively little consensus exists on how best to conduct them, and even less on how to ethically end them. The landscape of recent neural implant trials demonstrates wide variability of what happens to research participants after an neural implant trial ends. Some former research participants (...) continue to receive support for their devices (e.g., battery and component replacements, software updates, etc.). Others, when safe, have their neural implants removed through surgical explantation. Still others continue to live with a deactivated neural implant embedded in their body. In the United States, there are no uniform requirements to provide services, of any kind, after an neural implant study ends, and other nations are similarly facing this challenge. The existence of a post-trial gap in an expanding neural implant research ecosystem invites obvious questions: What is owed to neural implant research participants post-trial, and why has providing it been so difficult to accomplish in practice? To take a step forward on this difficult issue, we assembled one group of stakeholders – researchers funded for neuroethics grants by the National Institutes of Health – to explore possible starting points on one topic: ethical guidance for post-trial care of research participants in neural implant trials. Based on shared concerns discussed in the expert workshop the current paper is a call to action. It reports the key areas of convergence from the meeting and highlights important next steps towards developing much needed guidance. (shrink)

Robert Sternfeld and Harold Zyskind have prepared, with considerable attention to details, a conscientious commentary upon Plato’s Meno. They make some use of, even though they differ from, Jacob Klein’s "distinguished linear and linguistic commentary". The authors bring to bear on the Meno their studies in logic and rhetoric. Professor Sternfeld is the author of Frege’s Logical Theory; Professor Zyskind is the author of a rhetorical analysis of the Gettysburg Address.

This paper examines the issue of what the self is by reviewing neuropsychological research,which converges on the idea that the self may be more complex and differentiated than previous treatments of the topic have suggested. Although some aspects of self-knowledge such as episodic recollection may be compromised in individuals, other aspects—for instance, semantic trait summaries—appear largely intact. Taken together, these findings support the idea that the self is not a single, unified entity. Rather, it is a set of interrelated, functionally (...) independent systems. Implications for understanding the self in various areas of psychological research—e.g., neuroimaging, autism, amnesia, Alzheimer’s disease, and mirror self-recognition—are discussed in brief.

In this paper, I first consider a famous objection that the standard interpretation of the Lockean account of diachronicity (i.e., one’s sense of personal identity over time) via psychological connectedness falls prey to breaks in one’s personal narrative. I argue that recent case studies show that while this critique may hold with regard to some long-term autobiographical self-knowledge (e.g., episodic memory), it carries less warrant with respect to accounts based on trait-relevant, semantic self-knowledge. The second issue I address concerns the (...) question of diachronicity from the vantage point that there are (at least) two aspects of self—the self of psychophysical instantiation (what I term the epistemological self) and the self of first person subjectivity (what I term the ontological self; for discussion, see Klein SB, The self and its brain, Social Cognition, 30, 474–518, 2012). Each is held to be a necessary component of selfhood, and, in interaction, they are appear jointly sufficient for a synchronic sense of self (Klein SB, The self and its brain, Social Cognition, 30, 474–518, 2012). As pertains to diachronicity, by contrast, I contend that while the epistemological self, by itself, is precariously situated to do the work required by a coherent theory of personal identity across time, the ontological self may be better positioned to take up the challenge.

Inattentional blindness is described as the failure to perceive a supra-threshold stimulus when attention is directed away from that stimulus. Based on performance on an explicit recognition memory test and concurrent functional imaging data Rees, Russell, Frith, and Driver [Rees, G., Russell, C., Frith, C. D., & Driver, J. . Inattentional blindness versus inattentional amnesia for fixated but ignored words. Science, 286, 2504–2507] reported inattentional blindness for word stimuli that were fixated but ignored. The present study examined both explicit and (...) implicit memory for fixated but ignored words using a selective-attention task in which overlapping picture/word stimuli were presented at fixation. No explicit awareness of the unattended words was apparent on a recognition memory test. Analysis of an implicit memory task, however, indicated that unattended words were perceived at a perceptual level. Thus, the selective-attention task did not result in perfect filtering as suggested by Rees et al. While there was no evidence of conscious perception, subjects were not blind to the implicit perceptual properties of fixated but ignored words. (shrink)

In this paper I argue that much of the confusion and mystery surrounding the concept of "self" can be traced to a failure to appreciate the distinction between the self as a collection of diverse neural components that provide us with our beliefs, memories, desires, personality, emotions, etc (the epistemological self) and the self that is best conceived as subjective, unified awareness, a point of view in the first person (ontological self). While the former can, and indeed has, been extensively (...) studied by researchers of various disciplines in the human sciences, the latter most often has been ignored -- treated more as a place holder attached to a particular predicate of interest (e.g., concept, reference, deception, esteem, image, regulation, etc). These two aspects of the self, I contend, are not reducible -- one being an object (the epistemological self) and the other a subject (the ontological self). Until we appreciate the difficulties of applying scientific methods and analysis to what cannot be reduced to an object of inquiry without stripping it of its essential aspect (its status as subject), progress on the "self", taken as a pluralistic construct, will continue to address only one part of the problems we face in understanding this most fundamental aspect of human experience.

We study the logic of neighbourhood models with pointwise intersection, as a means to characterize multi-modal logics. Pointwise intersection takes us from a set of neighbourhood sets Ni (one for each member i of a set G used to interpret the modality □) to a new neighbourhood set NG, which in turn allows us to interpret the operator □G Here, X is in the neighbourhood for G if and only if X equals the intersection of some Y {Yi | Yi (...) ∈G}. We show that the notion of pointwise intersection has various applications in epistemic and doxastic logic, deontic logic, coalition logic, and evidence logic. We then establish sound and strongly complete axiomatizations for the weakest logic characterized by pointwise intersection and for a number of variants, using a new and generally applicable technique for canonical model construction.

I argue that appreciation of the phenomenon of forgetting requires serious attention to its origins and place in nature. This, in turn, necessitates metaphysical inquiry as well as empirical backing – a combination likely to be eschewed by psychological orthodoxy. But, if we hope to avoid the conceptual vacuity that characterizes too much of contemporary psychological inquiry (e.g., Klein, 2012, 2014a, 2015a, 2016a), a “big picture” approach to phenomena of interest is essential. Adopting this investigative posture turns the “received (...) view” of the relation between remembering and forgetting on its head: Rather than treated as the result of breakdowns and limitations of biologically engineered systems of remembering, forgetting is accorded elevated status as the driving force behind the evolution of organic systems of information retention.

In this paper I examine the concept of cross-temporal personal identity (diachronicity). This particular form of identity has vexed theorists for centuries -- e.g.,how can a person maintain a belief in the sameness of self over time in the face of continual psychological and physical change? I first discuss various forms of the sameness relation and the criteria that justify their application. I then examine philosophical and psychological treatments of personal diachronicity(for example,Locke's psychological connectedness theory; the role of episodic memory) (...) and find each lacking on logical grounds, empirical grounds, or both. I conclude that to achieve a successful resolution of the issue of the self as a temporal continuant we need to draw a sharp distinction between the feeling of the sameness of one's self and the evidence marshaled in support of that feeling.

S. Pockett and G. Gomes discuss a possible bias in the method by which Libet's subjects estimated the time at which they became aware of their intent to move their hands. The bias, caused by sensory delay processing the clock information, would be sufficient to alter Trevena and Miller's conclusions regarding the timing of the lateralized readiness potential. I show that the flash-lag effect would compensate for that bias. In the last part of my commentary I note that the other (...) target articles do not examine the most interesting aspect of Libet's unfashionable views on free will. I point out that Libet's views are less strange than they at first appear to be. (shrink)

Sustainability has become paramount in society and retail. Therefore, this study aims to compare the environmental sustainability of brick‐and‐mortar retail and e‐commerce. A literature review identifies various factors, such as buildings, shopping trips, order bundling, returns, packaging, transport and logistics, and environmentally conscious behavior, that determine the channel that is superior in terms of environmental sustainability. While these factors are context‐specific and depend on several actors (e.g., consumers, retailers, and logistics service providers), most studies consider e‐commerce to be more environmentally (...) friendly than purchases from brick‐and‐mortar stores. However, this review demonstrates that most previous studies have focused on objective criteria (e.g., CO2). Therefore, to reflect the importance of consumers' perspectives on channel choice, we conducted four empirical studies that provide insights into the perceived environmental sustainability of each channel. In contrast to experts' views, consumers perceive e‐commerce as less sustainable than brick‐and‐mortar retailing. Hence, online retailers should improve their communication strategies and highlight the potential environmental advantages of e‐commerce and omni‐channel retailing. Brick‐and‐mortar retailers are advised to reduce the environmental damage they cause and encourage their customers to act in an eco‐friendly manner. (shrink)

Although the dream narrative, of (bio)logical necessity, originates with the dreamer, s/he typically does not know this. For the dreamer, the dream world is the real world. In this article I argue that this nightly misattribution is best explained in terms of the concept of mental ownership (e.g., Albahari, 2006; Klein, 2015a; Lane, 2012). Specifically, the exogenous nature of the dream narrative is the result of an individual assuming perspectival, but not personal, ownership of content s/he authored (i.e., “The (...) content in my head is not mine. Therefore it must be peripherally perceived”). Situating explanation within a theoretical space designed to address questions pertaining to the experienced origins of conscious content has a number of salutatory consequences. For example, it promotes predictive fecundity by bringing to light empirical generalizations whose presence otherwise might have gone unnoticed (e.g., the severely limited role of mental time travel within the dream narrative). -/- .

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)

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)

I argue that academic psychology’s quest to achieve scientific respectability by reliance on quantification and objectification is deeply flawed. Specifically, psychological theory typically cannot support prognostication beyond the binary opposition of “effect present/effect absent”. Accordingly, the “numbers” assigned to experimental results amount to little more than affixing names (e.g., more than, less than) to the members of an ordered sequence of outcomes. This, in conjunction with the conceptual under-specification characterizing the targets of experimental inquiry, is, I contend, a primary reason (...) why psychologists find it difficult to discriminate between competing, explanations of the effects of mind on behavior. Absent well-specified theory capable of enabling precise and detailed quantitative prediction, inferring underlying mental mechanisms from experimental outcomes becomes a difficult, if not impossible, task.

It is shown that relativistic spacetimes can be viewed as Finslerian spaces endowed with a positive definite distance (ω0, mod ωi) rather than as pariah, pseudo-Riemannian spaces. Since the pursuit of better implementations of “Euclidicity in the small” advocates absolute parallelism, teleparallel nonlinear Euclidean (i.e., Finslerian) connections are scrutinized. The fact that (ωμ, ω0 i) is the set of horizontal fundamental 1-forms in the Finslerian fibration implies that it can be used in principle for obtainingcompatible new structures. If the connection (...) is teleparallel, a Kaluza-Klein space (KKS) indeed emerges from (ωμ, ω0 i), endowed ab initio with intertwined tangent and cotangent Clifford algebras. A deeper level of Kähler calculus, i.e., the language of Dirac equations, thus emerges. This makes the existance of an intimate relationship between classical differential geometry and quantum theory become ever more plausible. The issue of a geometric canonical Dirac equation is also raised. (shrink)

Recent advancements in neuroengineering research have prompted neuroethicists to propose a variety of “ethical guidance” frameworks (e.g., principles, guidelines, framing questions, responsible research innovation frameworks, and ethical priorities) to inform this work. In this chapter, we offer a comparative analysis of five recently proposed ethical guidance frameworks (NIH neuroethics guiding principles, Nuffield Council on Bioethics, Global Neuroethics Summit Delegates, the Center for Neurotechnology’s neuroethical principles and guidelines, and the Neurotechnology Ethics Taskforce’s ethical priorities). We identify some common themes among these (...) frameworks, making explicit significant areas of convergence. We also highlight three areas of ethical consideration that have not received sufficient attention across these frameworks (extended care for research participants, cultural salience, and stakeholder input). Further attention and analysis of these three areas would improve the breadth and scope of ethical considerations for neuroengineering research. (shrink)

The Dirac δ function has solid roots in nineteenth century work in Fourier analysis and singular integrals by Cauchy and others, anticipating Dirac’s discovery by over a century, and illuminating the nature of Cauchy’s infinitesimals and his infinitesimal definition of δ.

We examine some of Connes’ criticisms of Robinson’s infinitesimals starting in 1995. Connes sought to exploit the Solovay model S as ammunition against non-standard analysis, but the model tends to boomerang, undercutting Connes’ own earlier work in functional analysis. Connes described the hyperreals as both a “virtual theory” and a “chimera”, yet acknowledged that his argument relies on the transfer principle. We analyze Connes’ “dart-throwing” thought experiment, but reach an opposite conclusion. In S , all definable sets of reals are (...) Lebesgue measurable, suggesting that Connes views a theory as being “virtual” if it is not definable in a suitable model of ZFC. If so, Connes’ claim that a theory of the hyperreals is “virtual” is refuted by the existence of a definable model of the hyperreal field due to Kanovei and Shelah. Free ultrafilters aren’t definable, yet Connes exploited such ultrafilters both in his own earlier work on the classification of factors in the 1970s and 80s, and in Noncommutative Geometry, raising the question whether the latter may not be vulnerable to Connes’ criticism of virtuality. We analyze the philosophical underpinnings of Connes’ argument based on Gödel’s incompleteness theorem, and detect an apparent circularity in Connes’ logic. We document the reliance on non-constructive foundational material, and specifically on the Dixmier trace −∫ (featured on the front cover of Connes’ magnum opus) and the Hahn–Banach theorem, in Connes’ own framework. We also note an inaccuracy in Machover’s critique of infinitesimal-based pedagogy. (shrink)

A reprint of the 1951 translation of Kleines Lehrbuch des Positivismus, this work presents the positivist's view of the world for the layman, but introduces a few interesting variations on standard positivist positions. More space than is usual in similar books is devoted to a discussion of the social sciences, art, law, morality, and religion.--R. G. S.

Cauchy’s contribution to the foundations of analysis is often viewed through the lens of developments that occurred some decades later, namely the formalisation of analysis on the basis of the epsilon-delta doctrine in the context of an Archimedean continuum. What does one see if one refrains from viewing Cauchy as if he had read Weierstrass already? One sees, with Felix Klein, a parallel thread for the development of analysis, in the context of an infinitesimal-enriched continuum. One sees, with Emile (...) Borel, the seeds of the theory of rates of growth of functions as developed by Paul du Bois-Reymond. One sees, with E. G. Björling, an infinitesimal definition of the criterion of uniform convergence. Cauchy’s foundational stance is hereby reconsidered. (shrink)

The widespread idea that infinitesimals were “eliminated” by the “great triumvirate” of Cantor, Dedekind, and Weierstrass is refuted by an uninterrupted chain of work on infinitesimal-enriched number systems. The elimination claim is an oversimplification created by triumvirate followers, who tend to view the history of analysis as a pre-ordained march toward the radiant future of Weierstrassian epsilontics. In the present text, we document distortions of the history of analysis stemming from the triumvirate ideology of ontological minimalism, which identified the continuum (...) with a single number system. Such anachronistic distortions characterize the received interpretation of Stevin, Leibniz, d’Alembert, Cauchy, and others. (shrink)

An outline is given as to how gauge transformations in a frame fiber can be interpreted as defining various types of transport of a moving frame along a path. The cases of general linear, parallel, Lorentz, and other transport groups are examined in Minkowski space-time. A specific set of frame coordinates is introduced. A number of results are obtained including a generalization of Frenet-Serret transport, an extension of Fermi-Walker transport, a relation between frame spaces and certain types of Finsler space, (...) and a derivation of a Kaluza-Klein type metric. Frame transport in general Riemannian space-time is also discussed. (shrink)

This volume is third in a series, Monuments of Western Thought, which Cantor and Klein are editing at Colgate. The bulk of this book consists of excerpts from the work of Dante and Machiavelli. Of the Dante material, seventy-five pages is from the Divine Comedy, the rest from De Monarchia. Of the Machiavelli material, thirty pages are from The Prince, the rest excerpted from various works and arranged under such heads as "Warfare" and "Fortune." The text is introduced by (...) a sketch of the intellectual, social, and political context in which Dante and Machiavelli lived, and by brief intellectual biographies. The book closes with short critical selections, assessing and interpreting the source material. On Dante: E. Gilson deals with the ideological frame of the Divine Comedy, social order under divine Authority: J. A. Mazzeo with the hierarchy of light in the Paradiso; G. Santayana with Beatrice as woman and symbol. On Machiavelli: J. W. Allen argues that Machiavelli's originality lies in looking at men and affairs without concerning himself with what they ought to be and do; H. Butterfield that Machiavelli admired ancient Rome and advocated close imitation of her; F. Chabod argues that the theme of The Prince is that society is amorphous, waiting the impress of a dominant individual of supreme virtù; F. Meinecke that virtù, fortuna, and necessità are the basic themes of Machiavelli's thought. Each section is followed by a list of questions designed to challenge the student's understanding of what he has read and to send him back to the text.--L. G. (shrink)

Felix Klein classified geometries by their group structure. It is pointed out that a similar program has been in place for particle physics and canonical quantum mechanics.

In lieu of an abstract, here is a brief excerpt of the content:Ethics & the Environment 8.1 (2003) 74-92 [Access article in PDF] John Dewey's Aesthetic Ecology of Public Intelligence and the Grounding of Civic Environmentalism Herbert Reid and Betsy Taylor "[The problem is] that of recovering the continuity of esthetic experience with normal processes of living." John Dewey, Art as Experience "This is not a protest. Repeat. This is not a protest. This is some kind of artistic expression. Over." (...) --A call that went out on Metro Toronto police radios on May 16, 1998, the date of the first Global Street Party. Quoted from Naomi Klein, No LogoThis paper argues for the importance of John Dewey's aesthetic philosophy to recent efforts to cultivate civic environmentalism while critiquing narrowly conservationist environmentalisms. We call for a strong version of civic environmentalism oriented towards holistic integration of ecological [End Page 74] concerns into all aspects of social, political, economic, and cultural life. Such a civic environmentalism argues that it is not enough to strive to preserve enclaved 'wilderness' or 'biodiversity' (as important as that is). It argues also for fundamental changes in the political and economic status quo, because ecological havoc is understood to be integrally linked with the structural forces that are increasing inequality and weakening democratic publics. Strengthening of the civic commons is integral to protection of the environmental commons. If the environmental commons are the substantive goods in common which are the sustaining grounds of life, the civic commons are the institutions, collective memories, social networks, and skills that enable and inspire individuals to engage with each other in stewarding the common good. Such collective labor for the larger good requires some form of collective imagination which enables awareness of self and other (human or non-human) as inherently valuable. But beyond this, it requires perceptual and social infrastructures that nurture the ability to see self and other as emergent from and dependent on the supra-individual matrix that supports both life and individual. Central to such civic labor, is a non-dualistic understanding of individual/matrix. Such a non-dualistic understanding of self/other-in-matrix is central to political and ecological imaginations that are decentered from ethnic, species, class, gender, or other forms of domination and solipsism.John Dewey's work as a whole is a powerful call for such a non-dualistic understanding of individual-in-matrix, and few have better understood its connections to democracy. But, it is in his philosophy of art that Dewey describes most specifically the central importance of the aesthetic dimension of public culture to overcoming crippling dualisms of Western modernity that vitiate participatory engagement- individual/world, nature/culture, ends/means, leisure/work, art/science, aesthetic/ordinary. His writings on art have not been much utilized in the philosophical work for civic environmentalism. This paper argues for their relevance to its key goal of overcoming the segmentation of life ushered in by modernity and buttressed by these dualisms.We first give an overview of recent theories of civic environmentalism and the crises it engages of inequality, injustice, technocracy, corporatization, and the pervasive assault on place and thinning of public participation. Second, we look at the implications of Dewey'saesthetic ecology for an "environmentalism of daily life" that challenges the false dualisms of neo-liberalism and of technocratic professionalism that undermine place-based [End Page 75] forms of life and knowledge. Third, we draw on Dewey's aesthetic philosophy to suggest ways to rebuild democratic public space at the nexus of body, place, and commons. Finally, we briefly outline key philosophical questions that have emerged in our ethnographic and political study of Appalachian grassroots activisms, and that embody this sort of placed, democratic mobilization to protect the civic and environmental commons. American Environmentalism: Crisis and Challenge Toward the end of the last decade, veteran New York Times journalist and now independent writer Philip Shabecoff set out to engage "a broad spectrum of thoughtful and informed people within and without the environmental movement."

We analyze the developments in mathematical rigor from the viewpoint of a Burgessian critique of nominalistic reconstructions. We apply such a critique to the reconstruction of infinitesimal analysis accomplished through the efforts of Cantor, Dedekind, and Weierstrass; to the reconstruction of Cauchy’s foundational work associated with the work of Boyer and Grabiner; and to Bishop’s constructivist reconstruction of classical analysis. We examine the effects of a nominalist disposition on historiography, teaching, and research.
