Itamar Pitowsky's book, published in the Springer-Verlag Lecture Notes in Physics series, brings together several extremely interesting component investigations concerning the foundations of quantum mechanics. All deal with issues of probability including, in one case, the relation of probability to logic. It is a significant contribution, offering both new, nontrivial mathematical results, and provocative philosophical remarks about their significance.

This volume provides a broad perspective on the state of the art in the philosophy and conceptual foundations of quantum mechanics. Its essays take their starting point in the work and influence of Itamar Pitowsky, who has greatly influenced our understanding of what is characteristically non-classical about quantum probabilities and quantum logic, and this serves as a vantage point from which they reflect on key ongoing debates in the field. Readers will find a definitive and multi-faceted description of the (...) major open questions in the foundations of quantum mechanics today, including: Is quantum mechanics a new theory of (contextual) probability? Should the quantum state be interpreted objectively or subjectively? How should probability be understood in the Everett interpretation of quantum mechanics? What are the limits of the physical implementation of computation? The impact of this volume goes beyond the exposition of Pitowsky’s influence: it provides a unique collection of essays by leading thinkers containing profound reflections on the field. (shrink)

In Justice and Reconciliation in World Politics Catherine Lu argues that structural reconciliation, rather than interactional reconciliation, ought to be the primary normative goal for political reconciliation efforts. I suggest that we might have good reason to want to retain relational approaches – such as that of Linda Radzik – as the primary focus of reconciliatory efforts, but that Lu’s approach is invaluable for identifying the parties who ought to bear responsibility for those efforts in cases of structural injustice. First, (...) I outline Lu’s analysis of reconciliation, where she argues for the normative priority of structural approaches within the global political sphere, and propose that it will be useful to identify whether or not a relational account could instead identify underlying structural injustices. Second, I examine one particular relational account of reconciliation (based on Radzik’s account of atonement) and argue that this type of account brings to light underlying structural injustices of the kind Lu is concerned with. Finally, I identify an issue for relational accounts in identifying relevant responsible parties for reconciliation before returning to Lu’s structural account to address this gap. (shrink)

Resenha do livro de Ceticismo e Naturalismo: algumas variedades, de P. F. Strawson. Traduçáo de Jaimir Conte. Sáo Leopoldo: Editora Unisinos, 2008, 114 páginas.

Referindo-se ao capítulo 6 da minha Introduction to Logical Theory, o professor Calabria demonstra de modo correto e sistemático que, tal como exposta, a doutrina da pressuposição implica uma concepção da lógica que é substancialmente desviante tanto no que diz respeito à lógica tradicional como à lógica moderna clássica.

Explores proper timing and the arts of rulership in the work that inspired China's first emperor.

The Lüshi chunqiu was written for and inspired the king who united the warring state to become China's first emperor in 221 BCE. This book explicates the concept of "proper timing," proposing that it helps bring unity to the diverse eclectic content of the text. The book analyzes the roles of human nature, the justification for the existence of the state, and the significance of personal, historical and cosmic timing. An organic instrumental position emerges from the diverse theories contained in (...) the Lüshi chunqiu. The conclusion looks at ways to apply the Lüshi chunqiu’s philosophy to contemporary issues of time and timing, human nature, political order and constitutions, social and environmental ethics.

Nanotechnology shows great promise in a variety of applications with attractive economic and societal benefits. However, societal issues associated with nanotechnology are still a concern to the general public. While numerous technological advancements in nanotechnology have been achieved over the past decade, research into the broader societal issues of nanotechnology is still in its early phases. Based on the data from the Web of Science database, we applied the main path analysis, cluster analysis and text mining tools to explore the (...) main research fronts and hierarchical structure of these societal issues. We found that the research studies fell into four categories: "General Toxicity and EHS (Environment, Health and Safety)," "Medicine and Cytotoxicity," "Assessment and Regulation," and "Environment and Ecotoxicity." These research studies have disclosed much information about the potential effect of nanotechnology on public health and the environment. Relatively speaking, the studies on the assessment, regulation, preventive solutions, and environmental protection are just emerging. This finding indicates that an abundance of effort should be conducted on these emerging themes to maximize the benefits of nanotechnology while minimizing its potential harm. The implications for various parties in this domain are also presented. (shrink)

In the mid-nineteenth century George Boole formulated his ‘conditions of possible experience’. These are equations and ineqaulities that the relative frequencies of events must satisfy. Some of Boole's conditions have been rediscovered in more recent years by physicists, including Bell inequalities, Clauser Horne inequalities, and many others. In this paper, the nature of Boole's conditions and their relation to propositional logic is explained, and the puzzle associated with their violation by quantum frequencies is investigated in relation to a variety of (...) approaches to the interpretation of quantum mechanics. * While preparing this paper for publication I have learnt of the untimely death of Professor J. S. Bell, and I wish to dedicate the paper to his memory. This research was undertaken while I spent a sabbatical leave at Wolfson College, and the History and Philosophy of Science Department at the University of Cambridge. I would like to thank Michael Redhead and Jeremy Butterfield for their hospitality and for helpful discussions. A first draft of this paper has been distributed among the participants of the conference 'Einstein in Context' which was held in Israel, in April 1990.1 have benefited from the comments of many colleagues. I would like to thank in particular Arthur Fine who enlightened me on the prism models, David Albert. Maya Bar-Hillel. Yemima Ben-Menachem, Mara Beller. Simon Saunders, and Mark Steiner.

Lu Xun is considered by many scholars the most influential modern Chinese writer, likened to Tolstoy, Shakespeare and Goethe in both scope and cultural impact, to the extent that Lu Xun scholarship has earned its own formal appellative: ‘Luxunology’. This impact is due not only to the initial impact of Lu Xun's fiction, but also greatly to Mao Zedong's use of Lu Xun during the Cultural Revolution. The history of Lu Xun's early fiction is analogous to the various historical manifestations, (...) and original ‘spirit’, of Marxism. Through close readings of Lu Xun's early fiction, and then detailing the relationship between Mao Zedong's use of Lu Xun in the Cultural Revolution, I will explore Jacques Derrida's 1993 work Specters of Marx, especially focusing on Derrida's distinction between the ‘spirit’ and the ‘spectre’.

Lü-shih ch'un-ch'iu [Spring and Autumn of the House of Lü] appeared on the scene in 239 B.C. This was the latter part of the Warring States period. Our country's transition from slavery to feudalism had already been basically completed, but chaotic wars of secession among the feudal princes still occurred. Remnant forces of the slave system were still quite strong, and the restoration-counterrestoration struggle between the declining slave-owning class and the newly emerging landlord class was proceeding violently. Lü Pu-wei was (...) a careerist and plotter of the declining slave-owning class and a representative of the Confucians. In response to the needs of the slave-owning class's counterrevolutionary restoration, Lü adopted the tactic of "attacking the mind." He sneaked into the government of the newly emerging landlord class in the state of Ch'in and played the role of an ardent vanguard for restoration. This big commercial slave owner, who had originally run around among Ch'in, Chao, and other states, had amassed thousands of gold pieces at home and possessed more than ten thousand slaves. He played around with political conspiracies and became chancellor of the state of Ch'in. Before King Ying Cheng of Ch'in personally took power in 238 B.C., political power fell for a time into Lü's hands. Lü Pu-wei worked in collusion with Lao Ai, a eunuch he sponsored, and joined the industrial and commercial slave owners and the aristocratic slave owners to form a frenzied restorationist force. On the one hand, they formed factions to strengthen private interests, expanded their power, and prepared for an armed coup d'état. On the other hand, they took in riff-raff [literally, people who had surrendered and rebelled], assembled Confucian scholars, set to work on ideology, and grandly created public opinion for the restoration of the slave system. At that time, a reactionary adverse current favoring the restoration of the slave system hung over the state of Ch'in. Lü-shih ch'un-ch'iu, which was compiled under Lü's direction by his retainers, was the product of this adverse current. (shrink)

Educational institutions need to respond to global competitive problems, and branding has become a method for higher education institutions to differentiate themselves. Thus, this study attempted to investigate predictors of employee brand-based equity. A cross-sectional research design has been used to record the perception of the teachers, and data are collected using a convenience sampling technique. Before administrating the study on large scale, a pilot testing was conducted, and reliability of the scale and their items was ensured. Pilot testing results (...) indicated a satisfactory reliability level, and constructs correlations were in the assumed directions, which allowed to conduct the study on a large scale. A sample size of 400 was set, and questionnaires were distributed among the participants, out of which, 376 were received back, while 351 were left at the end after discarding incomplete responses. The left over and completed questionnaires indicate 88% response rate. Data have been analyzed through the Smart PLS software by applying the structural equation modeling technique. After establishment of the measurement model through reliability and validity, the structural model was used to test study hypotheses. All the study hypotheses were found statistically significant on the basis of t and p statistics. Results indicate that teacher’s emotional intelligence enhances teachers’ self-efficacy, which further improves their brand-based equity. Similarly, emotional intelligence increases teacher’s performance, which also increases their brand-based equity. Limitations and future directions of the study are also reported. (shrink)

This study investigates the attitudes of a group of low‐status women towards computers through a deliberately designed computer training programme. Four aspects of the women’s attitudes were examined, including computer anxiety, confidence, liking and usefulness. Data sources consist of pre‐ and post‐surveys and interviews with the participants. The results show that the participants’ attitudes towards computers improved greatly after attending the training course, especially in terms of the aspect of anxiety. It was also found that the instructor’s patience, repeated step‐by‐step (...) demonstrations, detailed notes presented with screen‐image snapshots, stand‐by tutors and a friendly learning environment were the main elements that effectively helped the learners increase their positive feelings towards learning to use computers. The study reveals that once women have opportunities to use computers and once they are adequately instructed, the majority will be connected to the digital world in no time. (shrink)

A generally covariant theory, written in the spirit of Bohm's theory of quantum potentials, which applies to spinless, non interacting, gravitating systems, is formulated. In this theory the quantum state ψ is coupled to the metric tensor g, and the effect of the “quantum potential” is absorbed in the geometry. At the same time, ψ satisfies a covariant wave equation with respect to the very same g. This provides sufficient constraints to derive 11 coupled equations in the 11 unknowns: ψ (...) and the components of the metric tensor gµv. The states of stable localized particles are identified, and vacuum-state solutions for both the Euclidean and the Lorentzian case are explicitly presented. (shrink)

In this paper, I develop an original view of the structure of space—called infinitesimal atomism—as a reply to Zeno’s paradox of measure. According to this view, space is composed of ultimate parts with infinitesimal size, where infinitesimals are understood within the framework of Robinson’s nonstandard analysis. Notably, this view satisfies a version of additivity: for every region that has a size, its size is the sum of the sizes of its disjoint parts. In particular, the size of a finite region (...) is the sum of the sizes of its infinitesimal parts. Although this view is a coherent approach to Zeno’s paradox and is preferable to Skyrms’s infinitesimal approach, it faces both the main problem for the standard view and the main problem for finite atomism, leaving it with no clear advantage over these familiar alternatives.

A testimony is somebody else’s reported experience of what has happened. It is an indispensable source of knowledge. It only gives us historical cognition, however, which stands in a complex relation to rational or philosophical cognition: while the latter presupposes historical cognition as its matter, one needs the architectonic “eye of a philosopher” to select, interpret, and organize historical cognition. Kant develops this rationalist theory of testimony. He also practices it in his own work, especially while theorizing about race as (...) a subject of natural philosophy. In three dedicated essays on this subject, he treats race from the standpoint of a philosophical investigator of nature (Naturforscher), who (as Kant puts it in the first Critique) learns from nature “like an appointed judge who compels witnesses to answer the questions he puts to them.” This view underwrites Kant’s use of travel reports (a type of testimony) in developing and defending his theory of race.

Advocates of an ‘extended evolutionary synthesis’ have claimed that standard evolutionary theory fails to accommodate epigenetic inheritance. The opponents of the extended synthesis argue that the evidence for epigenetic inheritance causing adaptive evolution in nature is insufficient. We suggest that the ambiguity surrounding the conception of the gene represents a background semantic issue in the debate. Starting from Haig’s gene-selectionist framework and Griffiths and Neumann-Held’s notion of the evolutionary gene, we define senses of ‘gene’, ‘environment’, and ‘phenotype’ in a way (...) that makes them consistent with gene-centric evolutionary theory. We argue that the evolutionary gene, when being materialized, need not be restricted to nucleic acids but can encompass other heritable units such as epialleles. If the evolutionary gene is understood more broadly, and the notions of environment and phenotype are defined accordingly, current evolutionary theory does not require a major conceptual change in order to incorporate the mechanisms of epigenetic inheritance. 1 Introduction 2 The Gene-centric Evolutionary Theory and the ‘Evolutionary Gene’ 2.1 The evolutionary gene 2.2 Genes, phenotypes, and environments 3 Epigenetic Inheritance and the Gene-Centred Framework 3.1 Treating the gene as the sole heritable material? 3.2 Epigenetics and phenotypic plasticity 4 Conclusion.

This study examines the mediating role of felt accountability and cost–benefit consideration in the relationship between implicit ethics institutionalization and ethical selling intention. The research hypotheses are developed and tested with data collected using a scenario‐based questionnaire. The research design proposes two types of ethical dilemmas. In the first dilemma, the insurance salespeople are told that the dishonest selling behavior will lead to a profitable outcome. In the second dilemma, the insurance salespeople are informed that the honest selling behavior will (...) lead to an unprofitable outcome. The findings show that implicit ethics institutionalization is positively related to felt accountability, cost–benefit consideration and ethical selling intention, while felt accountability and cost–benefit consideration could partially mediate the relationship between implicit ethics institutionalization and the insurance salespeople’s ethical selling intention. The study highlights the importance of implicit ethics institutionalization in sales ethics and helps researchers and practitioners to better understand the mediators of felt accountability and cost–benefit consideration through which implicit ethics institutionalization benefits ethical selling intention.

Kuhnʼs influential book, The Structure of Scientific Revolutions,1 is often viewed as a revolt against empiricist philosophy of science. However, Friedman has reminded us lately2 that the book was commissioned by logical positivists, who were delighted with the result. In fact, the book was part of the International Encyclopedia of United Science initiated by members of the Vienna Circle, whose first volumes were published in 1938.3 The project aimed at providing a systematic positivist perspective on all the sciences, from logic (...) and mathematics through linguistics and on to psychology and sociology. The publication of Structure as volume 12 of the encyclopedia was greeted enthusiastically by the editor, Carnap, as can be learned from the letters he wrote to Kuhn. There are several reasons for this reaction. First, as noted by Friedman, there is a resemblance between Kuhnʼs notion of changing paradigms and Carnapʼs philosophical ideas. Logical empiricism is “logical” because of its central tenet that scientific knowledge is the organization of facts within a conceptual structure; the existence of an appropriate conceptual structure is a precondition for the very possibility of scientific inquiry. Unlike Kant, however, the logical empiricists believed that the conceptual. (shrink)

It is a received view that Kant’s formal logic (or what he calls “pure general logic”) is thoroughly intensional. On this view, even the notion of logical extension must be understood solely in terms of the concepts that are subordinate to a given concept. I grant that the subordination relation among concepts is an important theme in Kant’s logical doctrine of concepts. But I argue that it is both possible and important to ascribe to Kant an objectual notion of logical (...) extension according to which the extension of a concept is the multitude of objects falling under it. I begin by defending this ascription in response to three reasons that are commonly invoked against it. First, I explain that this ascription is compatible with Kant’s philosophical reflections on the nature and boundary of a formal logic. Second, I show that the objectual notion of extension I ascribe to Kant can be traced back to many of the early modern works of logic with which he was more or less familiar. Third, I argue that such a notion of extension makes perfect sense of a pivotal principle in Kant’s logic, namely the principle that the quantity of a concept’s extension is inversely proportional to that of its intension. In the process, I tease out two important features of the Kantian objectual notion of logical extension in terms of which it markedly differs from the modern one. First, on the modern notion the extension of a concept is the sum of the objects actually falling under it; on the Kantian notion, by contrast, the extension of a concept consists of the multitude of possible objects—not in the metaphysical sense of possibility, though—to which a concept applies in virtue of being a general representation. While the quantity of the former extension is finite, that of the latter is infinite—as is reflected in Kant’s use of a plane-geometrical figure (e.g., circle, square), which is continuum as opposed to discretum, to represent the extension in question. Second, on the modern notion of extension, a concept that signifies exactly one object has a one-member extension; on the Kantian notion, however, such a concept has no extension at all—for a concept is taken to have extension only if it signifies a multitude of things. This feature of logical extension is manifested in Kant’s claim that a singular concept (or a concept in its singular use) can, for lack of extension, be figuratively represented only by a point—as opposed to an extended figure like circle, which is reserved for a general concept (or a concept in its general use). Precisely on account of these two features, the Kantian objectual extension proves vital to Kant’s theory of logical quantification (in universal, particular and singular judgments, respectively) and to his view regarding the formal truth of analytic judgments.

This article is an extension of my previous article, which describes pure knowing as the ability and criteria for making moral judgment.1 Due to apparent contradictions among Wang Yangming's statements, there are controversies over the evaluation and interpretation of Wang's idea of the relation between moral knowledge 2 and moral action. Generally, on the one hand, Wang admits that there are people who commit wrong actions even though they recognize that these actions are wrong. He claims not only that sages (...) possess pure knowing, but also that robbers feel ashamed to be called "robbers" through the working of pure knowing.3 On the other hand, he explicitly states that "There have never...

Doping is an important issue in competitive sports and poses potentially irreversible consequences to athletes. Understanding the psychological process underlying antecedents and doping intention will inform policy and prevention. This study aimed to test the psychosocial mechanisms of doping in adolescent athletes using an integrated model. In this model, we examined the associations of perceived motivational climate, moral variables, and attitudinal variables with doping intention. We further investigated whether the moral variables mediated the relationship between perceived motivational climate and doping (...) intention. A cross-sectional survey was employed in the present study. Six hundred and fifteen Chinese adolescent athletes completed questionnaires measuring demographic information and the variables mentioned previously. Structural equation modeling showed that the hypothesized model had a good fit and explained 64.1% of the variance in doping intention. Task-involving motivational climate indicated both directly and indirectly negative associations with doping intention via sportspersonship. The ego-involving motivational climate was positively associated with doping intention via moral disengagement. Among perceived pros/cons of doping and perceived cons of not doping, both perceived cons of doping and cons of not doping were positively associated with doping intention with a small effect size. This study confirmed the roles of tasking- and ego-involving motivational climates, moral variables, and attitudinal variables on doping intention. These research findings may provide new insights for the future of intention-based doping prevention programmes. (shrink)

Drug Safety Communications are used by the Food and Drug Administration to inform health care providers, patients, caregivers, and the general public about safety issues related to FDA-approved drugs. To assess patient knowledge of the messaging contained in DSCs related to the sleep aids zolpidem and eszopiclone, we conducted a large, cross-sectional patient survey of 1,982 commercially insured patients selected by stratified random sampling from the Optum Research Database who had filled at least two prescriptions for either zolpidem or eszopiclone (...) between July 1, 2012 and June 30, 2013. Among the 594 respondents, two-thirds reported hearing generally about drug safety information prior to starting a new drug, with the remaining one-third “rarely” or “never” hearing such information. Providers and pharmacists were primary sources of drug safety information. Two-thirds of zolpidem users and half of eszopiclone users reported having heard about the related DSC messages, ability to accurately identify the major factual messages was limited. Respondents reacted to new drug safety information about their sleep aids by reporting that they would want to learn about alternative ways to help them sleep and seek out more information about the safety of their specific sleeping pill. Opportunities may exist for the FDA to work with providers and pharmacies to help ensure the DSC information is more widely received and is more fully understood by those taking the affected medications.

Kochen and Specker’s theorem can be seen as a consequence of Gleason’s theorem and logical compactness. Similar compactness arguments lead to stronger results about finite sets of rays in Hilbert space, which we also prove by a direct construction. Finally, we demonstrate that Gleason’s theorem itself has a constructive proof, based on a generic, finite, effectively generated set of rays, on which every quantum state can be approximated. r 2003 Elsevier Ltd.

We develop and defend the thesis that the Hilbert space formalism of quantum mechanics is a new theory of probability. The theory, like its classical counterpart, consists of an algebra of events, and the probability measures defined on it. The construction proceeds in the following steps: (a) Axioms for the algebra of events are introduced following Birkhoff and von Neumann. All axioms, except the one that expresses the uncertainty principle, are shared with the classical event space. The only models for (...) the set of axioms are lattices of subspaces of inner product spaces over a field K. (b) Another axiom due to Soler forces K to be the field of real, or complex numbers, or the quaternions. We suggest a probabilistic reading of Soler's axiom. (c) Gleason's theorem fully characterizes the probability measures on the algebra of events, so that Born's rule is derived. (d) Gleason's theorem is equivalent to the existence of a certain finite set of rays, with a particular orthogonality graph (Wondergraph). Consequently, all aspects of quantum probability can be derived from rational probability assignments to finite "quantum gambles". (e) All experimental aspects of entanglement- the violation of Bell's inequality in particular- are explained as natural outcomes of the probabilistic structure. (f) We hypothesize that even in the absence of decoherence macroscopic entanglement can very rarely be observed, and provide a precise conjecture to that effect .We also discuss the relation of the present approach to quantum logic, realism and truth, and the measurement problem.
