72 1024x768 This paper presents evidence from the fields of cognitive science and quantum information theory suggesting quantum theory to be the dominant fundamental logic in the natural world, in direct challenge to the long-held assumption that quantum logic only need be considered ‘in the quantum realm.' A summary of the evolution of quantum logic and quantum theory is presented, along with an overview for the necessity of incomplete quantum knowledge, and some representative aspects of quantum logic. A case can (...) be made that classical logic and theory is a subset of quantum logic and theory, given that elements of quantum physics exist that can never admit classical understanding, including: Bell's theorem, Hardy's theorem, and the Pusey-Barrett-Rudolph theorem. Support can be found for the primacy of quantum logic in the natural world in the cognitive sciences, where recent research studies recognize quantum logic in studies of: the subconscious, decisions involving unknown interconnected variables, memory, and question sequencing.

Hermann Weyl, one of the twentieth century's greatest mathematicians, was unusual in possessing acute literary and philosophical sensibilities—sensibilities to which he gave full expression in his writings. In this paper I use quotations from these writings to provide a sketch of Weyl's philosophical orientation, following which I attempt to elucidate his views on the mathematical continuum, bringing out the central role he assigned to intuition.

This paper treats some of the issues raised by Putnam's discussion of, and claims for, quantum logic, specifically: that its proposal is a response to experimental difficulties; that it is a reasonable replacement for classical logic because its connectives retain their classical meanings, and because it can be derived as a logic of tests. We argue that the first claim is wrong (1), and that while conjunction and disjunction can be considered to retain their classical meanings, negation crucially does not. (...) The argument is conducted via a thorough analysis of how the meet, join and complementation operations are defined in the relevant logical structures, respectively Boolean- and ortholattices (3). Since Putnam wishes to reinstate a realist interpretation of quantum mechanics, we ask how quantum logic can be a logic of realism. We show that it certainly cannot be a logic of bivalence realism (i.e., of truth and falsity), although it is consistent with some form of ontological realism (4). Finally, we show that while a reasonable explication of the idealized notion of test yields interesting mathematical structure, it by no means yields the rich ortholattice structure which Putnam (following Finkelstein) seeks.

In what seems to have been his last paper, Insight and Reflection (1954), Hermann Weyl provides an illuminating sketch of his intellectual development, and describes the principal influences—scientific and philosophical—exerted on him in the course of his career as a mathematician. Of the latter the most important in the earlier stages was Husserl’s phenomenology. In Weyl’s work of 1918-22 we find much evidence of the great influence Husserl’s ideas had on Weyl’s philosophical outlook—one need merely glance through the pages of (...) Space-Time-Matter or The Continuum to see it. Witness, for example, the following passages from the former. (shrink)

IN THEIR WELL-KNOWN PAPER, Kochen and Specker (1967) introduce the concept of partial Boolean algebra (pBa) and show that certain (finitely generated) partial Boolean algebras arising in quantum theory fail to possess morphisms to any Boolean algebra (we call such pBa's intractable in the sequel). In this note we begin by discussing partial..

What responsibilities does each of us have to reduce or limit our greenhouse gas emissions? Advocates of individual emissions reductions acknowledge that there are limits to what we can reasonably demand from individuals. Climate ethics has not yet systematically explored those limits. Instead, it has become popular to suggest that such judgements should be ‘context-sensitive’ but this does not tell us what role different contextual factors should play in our moral thinking. The current approach to theory development in climate ethics (...) is not likely to be the most effective way to fill this gap. In existing work, climate ethicists use hypothetical cases to consider what can be reasonably demanded of individuals in particular situations. In contrast, ‘climate ethics with an ethnographic sensibility’ uses qualitative social science methods to collect original data in which real individuals describe their own situations. These real-life cases are more realistic, more detailed and cover a broader range of circumstances than hypothetical cases. Normative analysis of real-life cases can help us to develop a more systematic understanding of the role that different contextual factors should play in determining individual climate responsibilities. It can also help us to avoid the twin dangers of ‘idealization’ and ‘special pleading’. (shrink)

The imbalance between supply of organs for transplantation and demand for them is widening. Although the current international drive to re-establish procurement via non-heart beating organ donation/donor is founded therefore on necessity, the process may constitute a desirable outcome for patient and family when progression to brain stem death does not occur and conventional organ retrieval from the beating heart donor is thereby prevented. The literature accounts of this practice, however, raise concerns that risk jeopardising professional and public confidence in (...) the broader transplant programme. This article focuses on these clinical, ethical, and legal issues in the context of other approaches aimed at increasing donor numbers. The feasibility of introducing such an initiative will hinge on the ability to reassure patients, families, attendant staff, professional bodies, the wider public, law enforcement agencies, and the media that practitioners are working within explicit guidelines which are both ethically and legally defensible.

Canada’s Tri-Council Policy Statement: Ethical Conduct for Research Involving Humans mandates that all research involving human subjects be reviewed and approved by a research ethics board . We have little evidence on how researchers are dealing with this requirement in multisite studies, which involve more than one REB. We retrospectively examined 22 REB submissions for two minimal-risk, multisite studies in leading Canadian institutions. Most REBs granted expedited review to the studies, while one declared the application to be exempt from review. (...) Time between submission and approval ranged greatly, from four to 546 days. We received a total of 155 REB queries for changes and clarifications, most of which asked for further information, clarification, or additional documents. Less than a third of the REB queries were requests for specific changes, and a vast majority had a very limited impact on the research projects. Institutions also varied broadly in their description of what was required of local principal investigators. We conclude that the organizational and practical challenges these results imply could deter researchers from embarking on multisite research projects, and that recently proposed changes to the TCPS will not solve these problems.

This study examines the varying roles of power, status, and national culture in unethical decision-making. Most research on unethical behavior in organizations is grounded in Western societies; empirical comparative studies of the antecedents of unethical behavior across nations are rare. The authors conduct this comparative study using scenario studies with four conditions in both China and Canada. The results demonstrate that power is positively related to unethical decision-making in both countries. Status has a positive effect on unethical decision-making and facilitates (...) the unethical decisions of Canadian participants who have high power but not Chinese participants who have high power. To explicate participants’ unethical decision-making rationales, the authors ask participants to justify their unethical decisions; the results reveal that Chinese participants are more likely to cite position differences, whereas Canadian participants are more likely to cite work effort and personal abilities. These findings expand theoretical research on the relationship between social hierarchy and unethical decision-making and provide practical insights on unethical behavior in organizations. (shrink)

THE CLOSE CONNECTION BETWEEN mathematics and philosophy has long been recognized by practitioners of both disciplines. The apparent timelessness of mathematical truth, the exactness and objective nature of its concepts, its applicability to the phenomena of the empirical world— explicating such facts presents philosophy with some of its subtlest problems. Let me begin by reminding you of some celebrated past attempts made by philosophers and mathematicians to explicate the nature of mathematics.

. Management scholars and practitioners often believe that individuals and organizations benefit by trusting their work contacts. (Husted, 1998; Sonnenberg, 1994) Trust is generally viewed as “good” and imperative to a modern functioning economy (Blau, 1964; Hosmer, 1995; Zucker, 1986) Consequently, scholars and practitioners have given scant attention to the “downside” of trust, despite the fact that trust involves taking risk under conditions of uncertainty (Rousseau et al., 1998) Recent corporate scandals show that people suffer when they misplace trust in (...) untrustworthy organizations and individuals. This paper develops a model of the causes and consequences of “over-trust,” which we define as a state where a trustor’s trust exceeds that which is warranted given the conditions. The antecedents of overtrust related to characteristics of the trustee, the trustor, and situational characteristics. We examine the role played by self-monitoring and perceived power base of the trustee as two key trustee characteristics. Among trustor characteristics, we examine the role (played by trustor’s core evaluation, core values). based on cultural affiliation), prior experiences with trustees, and use of habitual thinking behavior. Under characteristics of the situation, we examine the role played by uncertainty inherent in the situation, perceived threat from the context, degree of task interdependence, and organizational systems and routines. Next, we examine three consequences of over-trust – leniency in judging the trustee, delay in perceiving exploitation, and increased risk-taking. We conclude our paper by developing a set of guidelines that organizational members may employ to avoid over-trust. (shrink)

Legislation that authorises controversial organ procurement strategies but ignores respect for autonomy is flawed in principle and predictably unworkable in practiceThe UK Human Tissue Act 2004,1 designed to regulate all activity involving human tissue, organs, or bodies, was introduced in the House of Commons in December 2003, received Royal Assent on 15 November 2004,2 and has been partially implemented by Commencement Orders from April 2005. The new act, which repeals and replaces the Human Tissue Act 1961, the Anatomy Act 1984, (...) and the Human Organ Transplants Act 1989, has its origins in events of serious public concern, namely the retained organs scandals at Bristol Royal Infirmary3 and the Royal Liverpool Childrens’ Hospital.4 The act is correspondingly dominated by regulation of postmortem examinations and retention of human tissue, with consistent emphasis on the need for fully informed consent. Compliance with these requirements is now mandatory with the threat of up to three years’ imprisonment and/or fines for any deviation.The impact of the original proposals within the bill on research and the clinical practice of pathology have been carefully considered and documented,5 with subsequent amendments to ameliorate professional concerns.6 The act, however, also carries significant implications for medical practice in areas where donor recruitment for transplantation can take place, and representations on these aspects during readings of the bill7 have produced neither clarification, justification, nor amendment within the final legislation.Section 43 will make it lawful for hospital authorities “to take steps for the purpose of preserving the part for use for transplantation and to retain the body for that purpose”. The original explanatory notes for the bill8 while it proceeded through parliament implied that such action, prior to consent to transplantation being sought, was then lawful, clause 44 as section 43 ….

Everyday ethics refers to those issues which have a sometimes unrecognized moral dimension and that arise regularly within healthcare and research. These issues are often contrasted to dramatic ethics issues (i.e. issues that have seemingly higher stakes such as those arising in acute care situations or with invasive or life-threatening interventions). Claims have been made that scholarly bioethics tends to focus on dramatic ethics to the detriment of everyday ethics discussions. However, empirical evidence showing this has been lacking. Our own (...) research investigating bioethics discussions in the Parkinson’s disease literature suggested this trend. Consequently, we decided to characterize the context and content of the Parkinson’s disease bioethics literature to empirically test the hypothesis that everyday ethics is under discussed. We conducted a broad literature search using the keywords “Parkinson’s disease” AND (“ethics” OR “bioethics”) and classified results inductively based on the context in which the bioethics discussion occurred. In line with our hypothesis and initial observations, we found that there is indeed a greater focus on dramatic ethics where topics such as deep brain stimulation and neuronal cell transplantations, dominated bioethics discussions. Given the potential utility of everyday ethics in improving healthcare and research, this mismatch in focus ought to be addressed. There is a clear need for further understanding and discussion of everyday ethical issues in scholarly bioethics. (shrink)

In 1967, after a talk Deleuze gave to the Society of French Philosophy, Ferdinand Alquiéé expressed concern during the question and answer session that perhaps Deleuze was relying too heavily upon science and not giving adequate attention to questions and problems that Alquiéé took to be distinctively philosophical. Deleuze responded by agreeing with Alquiéé; moreover, he argued that his primary interest was precisely in the metaphysics science needs rather than in the science philosophy needs. This metaphysics, Deleuze argues, is to (...) be done ‘‘in the style of Whitehead’’ rather than the style of Kant, and in developing this metaphysics Deleuze draws heavily on Spinoza. The present essay examines this Deleuzian-Spinozist metaphysics done in the style of Whitehead, the ‘‘metaphysics science needs’’, drawing on the writings of David Hume and Bruno Latour in the process. This discussion will in turn enable us to situate Deleuze's metaphysics in relation to contemporary debates concerning speculative realism and correlationism, and especially Quentin Meillassoux's critique of the latter. Our conclusion will be that the kind of metaphysics Deleuze pursues is neither correlationist nor straightforwardly realist, but rather charts a course between realism and anti-realism. (shrink)

This article critically evaluates and contests the flagship benefit delivery system Universal Credit for lone mothers by focusing on some of the ethical challenges it poses, as well as some key implications it holds for social work with lone mothers and their children. Universal Credit was first introduced in the United Kingdom (UK) in 2008, and echoes conditionality-based welfare policies adopted by neoliberal governments internationally on the assumption that paid employment offers a route out of poverty for citizens. However, research (...) evidence suggests that the risks of conditionality polices for lone parents can often include increased poverty, a deterioration in mental health or even destitution posed by paternalistic sanctions or precarious low-paid employment, which can undermine parenting capacities and children’s well-being. The article also critically appraises and questions challenges posed by an increased reliance upon contractual ethics by governments, alongside the wider behaviour-modifying policies of the workfare-orientated state. This includes that working-class lone mothers can erroneously be stigmatised as representing a morally challenged dependent burden through activation policies and risk-averse social work practices.

This essay is an attempt to sketch the evolution of type theory from its beginnings early in the last century to the present day. Central to the development of the type concept has been its close relationship with set theory to begin with and later its even more intimate relationship with category theory. Since it is effectively impossible to describe these relationships (especially in regard to the latter) with any pretensions to completeness within the space of a comparatively short article, (...) I have elected to offer detailed technical presentations of just a few important instances. (shrink)

The last few years have seen an explosion of medieval images in digital form, chiefly as a result of photo-library and manuscript digitisation projects. An entire corpus of images, even selected solely by scene or iconography, becomes an unwieldy object of study by traditional art-historical means. This is even more the case for medieval images, where authorship and dating are often cloudy and unclear, and the image itself is in many cases the first resource for scholarly inquiry.We take the digital (...) image – in particular, the digital image of the body – as our object of study in a wide-ranging computationally-augmented reading of an image-corpus; ours is made up of thousands of depictions of the ‘Annunciation’ and ‘Baptism’, selected not only for their primacy in Christian art but for their dialogical interaction. Our corpus of 6,564 ‘Annunciations’ and 883 ‘Baptisms’, whilst not necessarily representative in density, includes a wide range of stylistic, theological and historical tendencies.We computationally extract not only body images but poses, gestures and interactions. Such a range of gestures allows for a morphological treatment of bodily motifs, whose multi-dimensional, quantitative nature allows us to complicate and problematise iconographic taxonomies, populating the spaces between categories. Finally, our gestural manifolds provide a morphological pointer to dissecting the microtemporalities of the scenes, and their relative dynamics and inconsistencies. (shrink)

Based upon research done by evolutionary psychologists into the reason why human beings feel depression in social situations, I argue that philosophers have significant warrant to consider depression as an important feature conditioning moral imagination. The moral imagination come up with new enterprises and new ways of organizing social life. This reorganization would meet many of the goals put forth by pragmatist philosopher John Dewey. I argue that depression will work as a leading clue and unique imaginative “space” to reconstruct (...) various social situations. (shrink)

In this article, we discuss the relationships between discrimination, harassment, and the glass ceiling, arguing that many of the factors that preclude women from occupying executive and managerial positions also foster sexual harassment. We suggest that measures designed to increase numbers of women in higher level positions will reduce sexual harassment. We first define and discuss discrimination, harassment, and the glass ceiling, relationships between each, and relevant legislation. We next discuss the relationships between gender and sexual harassment, emphasizing the influence (...) of gender inequality on sexual harassment. We then present recommendations for organizations seeking to reduce sexual harassment, emphasizing the role that women executives may play in such efforts and, importantly, the recursive effects of such efforts on increasing the numbers of women in higher level positions in organizations.

is a presentation of mathematics in terms of the fundamental concepts of transformation, and composition of transformations. While the importance of these concepts had long been recognized in algebra (for example, by Galois through the idea of a group of permutations) and in geometry (for example, by Klein in his Erlanger Programm), the truly universal role they play in mathematics did not really begin to be appreciated until the rise of abstract algebra in the 1930s. In abstract algebra the idea (...) of transformation of structure (homomorphism) was central from the beginning, and it soon became apparent to algebraists that its most important concepts and constructions were in fact formulable in terms of that idea alone. Thus emerged the view that the essence of a mathematical structure is to be sought not in its internal constitution, but rather in the nature of its relationships with other structures of the same kind, as manifested through the network of transformations. This idea has achieved its fullest expression in category theory, an axiomatic framework within which the notions of transformation (as morphism or arrow) and composition (and also structure, as object) are fundamental, that is, are not defined in terms of anything else.

This book offers an extended comparison of the philosophies of Gilles Deleuze and David Hume. The book argues that Deleuze's early work on Hume was instrumental to Deleuze's formulation of the problems and concepts that would remain a focus of his entire corpus. Reading Deleuze's work in light of Hume's influence, along with a comparison of Deleuze's work with William James, Henri Bergson and others set the stage for a vigorous defence of his philosophy against a number of recent criticisms (...) and extend the field of Deleuze studies by showing how Deleuze's thought can clarify and contribute to the work being done in political theory, cultural studies, and history, particularly the history of the Scottish Enlightenment. By engaging Deleuze's thought with the work of Hume, this book clarifies and supports the work of Deleuze and exemplifies the continuing relevance of Hume's thought to a number of contemporary debates.

“Lambeth Palace is my Washpot. Over Fulham have I cast my breeches.” So declared the novelist and secularist H. G. Wells in a letter to his mistress, Rebecca West, in May 1917. His claim was that, because of him, Britain was “full of theological discussion” and theological books were “selling like hot cakes”. He was lunching with liberal churchmen and dining with bishops. Certainly, the first of the books published during Wells’s short “religious period”, the novel Mr. Britling Sees It (...) Through, had sold very well on both sides of the Atlantic and made Wells financially secure. Geoffrey Studdert Kennedy (“Woodbine Willie”) wrote that, “Everyone ought to read Mr. H. G. Wells’s great novel, Mr. Britling Sees It Through. It is a gallant and illuminating attempt to state the question, and to answer it. His thought has brought him to a very real and living faith in God revealed in Jesus Christ, and has also brought relief to many troubled minds among the officers of the British Army.” Yet, Wells’s God was explicitly a finite God, and his theology was far from orthodox. How can we account for his boast and for the clerical affirmation which he certainly did receive? This article examines and re-evaluates previous accounts of the responses of clergy to Wells’s writing, correcting some narratives. It discusses the way in which many clergy used Mr. Britling as a means by which to engage in a populist way with the question of theodicy, and examines the letters which Wells received from several prominent clerics, locating their responses in the context of their own theological writings. This is shown to be key to understanding the reaction of writers such as Studdert Kennedy to Mr. Britling Sees It Through. Finally, an assessment is made of the veracity of Wells’s boasting to his mistress, concluding that his claims were somewhat exaggerated. “Lambeth Palace is my Washpot, Over Fulham have I cast my breeches.” Mit diesen Worten erklärte der literarisch außergewöhnlich erfolgreiche und entschieden säkular denkende, kirchenkritische Schriftsteller und Science-Fiction-Pionier Herbert George Wells seiner Geliebten, dass seinetwegen Großbritannien “full of theological discussion” sei. Nicht ohne Eitelkeit schrieb er es seinem im September 1916 mit Blick auf den Krieg geschriebenen und stark autobiographisch gefärbten Roman Mr. Britling Sees it Through von knapp 450 Seiten zu, dass theologische Bücher reißenden Absatz fänden. Auch war er stolz darauf, liberale Kleriker zum Lunch zu treffen und von Bischöfen zum abendlichen Dinner eingeladen zu werden. In einer kurzen Phase seines Lebens war – oder inszenierte sich – Wells als ein frommer, gläubiger Mensch. Sein damals veröffentlichter Roman Mr. Britling Sees It Through verkaufte sich sowohl in Nordamerika als auch im Heimatland so gut, dass der Autor nun definitiv finanziell gesichert war. Der anglikanische Priester und Dichter Geoffrey Studdert Kennedy, der im Ersten Weltkrieg Woodbine Willie genannt wurde, weil er verletzten und sterbenden Soldaten in den Phasen der Vorbereitung auf den Tod Woodbine-Zigaretten anbot, empfahl die Lektüre von Wells’ “great novel” Mr. Britling mit den Worten: “It is a gallant and illuminating attempt to state the question, and to answer it. His thought has brought him to a very real and living faith in God revealed in Jesus Christ, and has also brought relief to many troubled minds among the officers of the British Army.” Allerdings war H. G. Wells’ Gott ein durchaus endlicher Gott, und seine Theologie war alles andere als orthodox. Wie lassen sich dennoch seine evidente Prahlerei und die emphatische Zustimmung zu seinem Roman in den britischen Klerikereliten erklären? Im Aufsatz werden zunächst einige ältere Deutungen der Zustimmung führender Kleriker zu Wells’ Roman untersucht und einige der dabei leitenden Deutungsmuster kritisch infrage gestellt. Deutlich wird, dass nicht wenige anglikanische Geistliche Mr. Britling dazu nutzten, um höchst populistisch das umstrittene Theodizeeproblem anzusprechen. Auch werden die Briefe prominenter Geistlicher an Wells analysiert, mit Blick auf ihre eigenen Publikationen. Diese Reaktionen haben stark Studdert Kennedys Haltung zu Mr. Britling Sees It Through beeinflusst. Besonders aufrichtig war Wells mit Blick auf sich selbst allerdings nicht. Die Selbstinszenierung gegenüber seiner Geliebten war einfach nur peinliche Übertreibung. (shrink)

Innovations in information technologies have facilitated the development of new styles of research networks and forms of governance. This is evident in genomics where increasingly, research is carried out by large, interdisciplinary consortia focussing on a specific research endeavour. The UK10K project is an example of a human genomics consortium funded to provide insights into the genomics of rare conditions, and establish a community resource from generated sequence data. To achieve its objectives according to the agreed timetable, the UK10K project (...) established an internal governance system to expedite the research and to deal with the complex issues that arose. The project’s governance structure exemplifies a new form of network governance called ‘pop-up’ governance. ‘Pop-up’ because: it was put together quickly, existed for a specific period, was designed for a specific purpose, and was dismantled easily on project completion. In this paper, we use UK10K to describe how ‘pop-up’ governance works on the ground and how relational, hierarchical and contractual governance mechanisms are used in this new form of network governance.
