The abstract description of a physical system is developed, along lines originally suggested by Birkhoff and von Neumann, in terms of the complete lattice of propositions associated with that system, and the distinction between classical and quantum systems is made precise. With the help of the notion of state, a propositional system is defined: it is remarked that every irreducible propositional system (of more than three dimensions) is isomorphic to the lattice of all closed subspaces of a Hilbert space constructed (...) on some division ring with involution. The propositional system consisting of a family of separable complex Hilbert spaces is treated as a particular case which is sufficiently general to include both classical and quantum mechanics. The theory of the Galilean particle without spin is given as an illustration. Finally, the basis for the statistical interpretation of wave mechanics is developed with the help of Gleason's theorem. In an appendix, a proof of essentially the first part of Gleason's theorem is given which is a little different (perhaps more geometric) from that originally given by Gleason. (shrink)

Next SectionThe dominant conception of medical ethics being taught in British and American medical schools is at best pointless and at worst dangerous, or so it will be argued. Although it is laudable that medical schools have now given medical ethics a secure place in the curriculum, they go wrong in treating it like a scientific body of knowledge. Ethics is a unique subject matter precisely because of its widespread familiarity in all areas of life, and any teaching has to (...) start from this shared ethical understanding and from the familiar ethical concepts of ordinary language. Otherwise there is a real risk that spurious technocratic jargon will be deployed by teacher and student alike in the futile search for intellectual respectability, culminating in a misplaced sense of having “done” the ethics module. There are no better examples of such jargon than “consequentialism”, “deontology”, and the “Four Principles”. At best, they cannot do the work they were designed to do and, at worst, they can lead student and practitioner into ignoring their own healthy ethical intuitions and vocabulary. (shrink)

In his own writings, Rawls purposively used only a loose characterization of the basic structure, but two prominent misinterpretations highlight the current need for a more detailed account. First, G.A. Cohen argues that the Rawlsian focus on the basic structure is arbitrary due to the Rawlsian appeal to profound effects. Second, some theorists conflate the justification of coercion with the assessment of a basic structure by defining the basic structure as the coercive structure. Both misinterpretations can be corrected by carefully (...) specifying what social institutions are and explaining which social institutions come together to form the basic structure of society.

A defining characteristic of Alzheimer’s disease is difficulty in retrieving semantic memories, or memories encoding facts and knowledge. While it has been suggested that this impairment is caused by a degradation of the semantic store, the precise ways in which the semantic store is degraded are not well understood. Using a longitudinal corpus of semantic fluency data, we derive semantic network representations of patients with Alzheimer’s disease and of healthy controls. We contrast our network-based approach with analyzing fluency data with (...) the standard method of counting the total number of items and perseverations in fluency data. We find that the networks of Alzheimer’s patients are more connected and that those connections are more randomly distributed than the connections in networks of healthy individuals. These results suggest that the semantic memory impairment of Alzheimer’s patients can be modeled through the inclusion of spurious associations between unrelated concepts in the semantic store. We also find that information from our network analysis of fluency data improves prediction of patient diagnosis compared to traditional measures of the semantic fluency task. (shrink)

The academic literature in research ethics has been marked in the past decade by a much broader focus on the need for the protection of developing communities subjected to international clinical trials. Because of the proximity of the revision of the Declaration of Helsinki, completed in October 2008, most papers have addressed the issue of a double standard of care following the use of placebo. However, other no less important issues, such as interactions between the lifestyles structures of low-income communities (...) and the efficiency of risk-minimising procedures also deserve attention. The purpose of this paper is to discuss forms of uncertainty involved in clinical trials in poor and low-income countries that are not addressed by conventional methods of risk assessment. Furthermore, the increase in size of risks that are identified by conventional assessment methods will be addressed. Besides, the difficulty in properly applying risk-minimising procedures will be discussed. Finally, this paper proposes the involvement of research ethics committees in the risk evaluation process and the establishment of national ethics evaluation systems. (shrink)

Chalmers' (2018) meta-problem of consciousness emphasizes unexpected common ground between otherwise incompatible positions. We argue that the materialist should welcome discussion of the meta-problem. We suggest that the core of the metaproblem is the seeming arbitrariness of subjective experience. This has an unexpected resolution when one moves to an interventionist account of scientific explanation: the same interventions that resolve the hard problem should also resolve the meta-problem.

In the majority of academic institutions nursing and medical students receive a traditional education, the content of which tends to be specific to their future roles as health care professionals. In essence, each curriculum design is independent of each course. Over the last decade, however, interest has been accumulating in relation to interprofessional and multiprofessional learning at student level. With the view that learning together during their student training would not only encourage and strengthen future collaboration in practice settings but (...) also enhance patient care, the University of Dundee decided to run a pilot study to explore shared teaching in ethics between medical and nursing students. This article presents a report on the reasons for selecting health care ethics as a precursor for shared teaching, the educational tool used for the sessions, and the results of student and facilitator evaluation of the short course. Overall, despite problems such as poor attendance by some students, and facilitation and timetable difficulties, most of the feedback from students and facilitators has been positive. In essence the ‘idea’ has gone from strength to strength and there are now three levels of shared teaching in ethics between nursing and medical students, with plans to include further sessions with students from other disciplines. Within the text, ‘health care ethics’ will be referred to as ‘ethics’; nursing students/nurses encompasses midwifery students/midwives. (shrink)

Any theory of information needs to comply with what we call the implementation, formalization, and representation constraints. These constraints are justified by basic considerations concerning scientific modelling and methodology. In the first part of this paper, we argue that the implementation and formalization constraints cannot be satisfied because the relation between Shannon information and IIT must be clarified. In the second part of the paper, we focus on the representation constraint. We argue that IIT cannot succeed in satisfying this constraint (...) for semantic contents without offering models for concepts, conceptual roles, and context sensitivity. In the final part of the paper, further complications are raised with respect to the distinction between consciousness and attention, which apply more specifically to the representation constraint. We conclude with some recommendations as to how IIT may succeed in solving these problems, highlighting the advantages and enormous potential of IIT as a scientific theory. (shrink)

The Holocaust marks a decisive moment in modern suffering in which it becomes almost impossible to find meaning or redemption in the experience. In this study, C. Fred Alford offers a new and thoughtful examination of the experience of suffering. Moving from the Book of Job, an account of meaningful suffering in a God-drenched world, to the work of Primo Levi, who attempted to find meaning in the Holocaust through absolute clarity of insight, he concludes that neither strategy works well (...) in today's world. More effective are the day-to-day coping practices of some survivors. Drawing on testimonies of survivors from the Fortunoff Video Archives, Alford also applies the work of Julia Kristeva and the psychoanalyst Donald Winnicot to his examination of a topic that has been and continues to be central to human experience.

We extend the work of Ivancovsky et al. by proposing that in addition to novelty seeking, mood regulation goals – including enhancing positive mood and repairing negative mood – motivate both creativity and curiosity. Additionally, we discuss how the effects of mood on state of mind are context-dependent (not fixed), and how such flexibility may impact creativity and curiosity.

Bizarre delusions are not specific to schizophrenia and can be found in other psychotic disorders. However, to date, there are no studies investigating socio-demographic and clinical characteristics associated with BizD across the psychosis spectrum. In this study 819 subjects with a diagnosis of SZ, schizoaffective disorder and bipolar I disorder were included. Patients with history of BizD and with no BizD were compared with respect to socidemographic and clinical variables, and predictors of BizD were explored. Patients with BizD were less (...) educated, less likely to be married, had higher Positive and Negative Syndrome Scale negative scores and lower Young Mania Rating Scale scores. Younger age, SZ and SZA diagnoses, higher PANSS positive scores, presence of reference delusions, tactile and olfactory hallucinations were predictors. Our results indicate that BizD are associated with higher illness severity, lower functionality and specific set of symptoms. (shrink)

Originally presented as the author's doctora thesis (Boston U., 1962) under the title Horatio W. Dresser and the Philosophy of New Thought. Supplementary bibliographical notes and an addendum outlining the author's further thoughts accompany this presentation. Annotation c. by Book News, Inc., Portland, Or.

I present three problems regarding the Problem of the Base. They concern the nature of information, the kind of Platonism that physicalists allegedly confront, and the constraints imposed by causal principles. These problems focus on the notion of information and its relation to the Problem of the Base. I also highlight the importance of Schneider's paper, particularly its relevance for future debates.

Makalenin konusu Ebû Hanîfe örneğinden hareketle İslam düşüncesinde yargı-siyaset ilişkisi-dir. Ebû Hanîfe’nin yaşadığı döneme kadar karizmanın dini ve siyasi kültürde gelişimine paralel olarak yargı-siyaset ilişkileri bağlamında İslam düşüncesinde bazı formlar çoktan ortaya çık-mıştı. Burada amaç İslam’ın henüz ikinci asrında yargı-siyaset ilişkilerini Ebû Hanîfe üzerinden anlamaya çalışmak ve dolaylı olarak da meselenin bugüne yansıyan yönlerine ışık tutmaktır. Bu yüzden farklı sosyolojik düzlemlerde inşa edilmiş Şiî, Haricî, Sünnî öteki formlar çalışma dışında tutulmuştur. Araştırma Ebû Hanîfe’nin; doktrini oluşturan Kur’an, sünnet ve sahabe uygulamaları (...) ile kendi dönemindeki dini, siyasi, sosyal ve kültürel şartlar arasında nasıl bir okuma yaptığını sorunsallaştırmıştır. Çalışmada Ebû Hanîfe’nin yargı-siyaset ilişkisi bağlamın-da ortaya çıkardığı genel anlama biçiminin, işaret edilen dini ve tarihi şartlarla kendi dini top-lumsallaşma çevresindeki diyalektik bir ilişkide şekillendiği varsayılmıştır. Dolaylı gözlem yöntemi ile elde edilen veriler bir tekil olay incelemesi bağlamında fenomenolojik bir çözüm-lemeye tabi tutulmuştur. Konu bugüne kadar ilahiyat bağlamında olduğu gibi din bilimi alanın-da da dikkat çekici görülmemiştir. Makale İslam düşüncesinde yargı-siyaset ilişkisinin farklı desenleri arasında Ebû Hanîfe modelini tartışması bağlamında bir değere sahip görülebilir. Çalışmada; temel hak ve özgürlüklerin korunması noktasında sivil ve barışçıl bir muhalefetin yeterli olmadığı, iktidarın kişisel hakları tanımaktan daha çok kişisel ödevler ve mutlak itaat talebi ile siyaset yaptığı bir ortamda Ebû Hanîfe’nin soruna ahlaki bir saikle yaklaştığı ve bu bağlamda bir çözüm önerisi getirdiği görülmüştür. Ebû Hanîfe gerek otorite ve karizması ge-rekse ekonomik statüsü ve kültürel birikiminden aldığı güç ile yaşadığı dönemde üst düzey siyasal ve hukuki bir katılım gerçekleştirmiştir. Yasama erkinin özgür bir üyesi olarak Ebû Hanîfe temel haklar bağlamında hayatı boyunca hep iktidarlarla karşı karşıya gelmiş ve bu mücadele içinde iken de öldürülmüştür. Müslüman bir ailede doğmasına rağmen dönemin politik tavrı nedeniyle daha doğumuyla birlikte iktidar tarafından öteki olarak görülmüş ve ömrü boyunca bu statü ile yaşamak zorunda kalmıştır. Başlangıçta kendi ailesi içinde toplum-sallaşırken deneyimlediği mevalilik duygusu, Ebû Hanîfe’de özellikle hocasının ölümünden sonra iktidarlara karşı toplumsal bir hak arayışına dönüşmüştür. Esasen kendi özelinde bir hak arayışı olmaksızın iktidarların yasa ile sorunlu politik tavırları karşısında dini, hukuki ve top-lumsal bir tavır içinde yürüttüğü bu mücadelesi Ehl-i Beyt’i ve diğer bütün toplumsal grup ve kategorileri içine alan bir genişlikte ilerlemiştir. Ebû Hanife’nin yargı- siyaset ilişkisine dair bu yaklaşımı teorik ve pratik olarak tamamen sistematik bir çerçevede şekillenmiştir. İslam hu-kukunun dayandığı bilgi gövdeleri kapsamında o, çok kapsayıcı ve dinamik bir tarzda din ve şeriat kavramsallaştırması yapmıştır. Buna göre Ebû Hanîfe dine temel hakların dayandığı temel yasa anlamı yüklerken şeriata ise kendisinin bu dini alana veya başka bir ifadeyle yasaya göre düzenlendiği neshe açık, değişken bir alan anlamı vermiştir. Bu tevhit eksenli hiyerarşi içinde siyaset, yasaya karşı kesin sorumluluğu olan dünyevi bir alan görülmüştür. Ebû Hanîfe’nin İslam’ın ilk dönemini bir hukuk devleti nosyonu içinde değerlendirdiğinde kuşku yoktur. Buna mukabil, genel yargı-siyaset ilişkisine yaklaşımından anlaşıldığına göre yaşadığı dönemi, iktidarlar tarafından hukukun araçsallaştırıldığı bir dönem olarak görmüştür. Kurmuş olduğu akademi onun yargı-siyaset ilişkisine bakışının önemli bir pratiğidir. Bu akademiden yetişen ve daha sonra resmi ve gayri resmi olarak yasamanın bir üyesi olan öğrencilerine tav-siyeleri ve mektupları, onun bir yargı elemanı olarak siyaset kurumuna yaklaşımının sübjektif değil; bir düzen ihtiyacının ortaya çıkardığı objektif bir tavır olduğunu göstermiştir. Ebû Hanîfe teorik yaklaşımını pratik bir eylem alanı ile birleştirmek suretiyle yargı-siyaset ilişkisine bakışı konusunda oldukça net bir fotoğrafa sahiptir. (shrink)

Nearly all Disney movies represent to people mere possibilities. One can conceive of scenarios with genies, wooden puppets coming to life, flying elephants, and mermaids. And there certainly seems to be no special problem in conceiving of a scenario where all the author's experiences are a mere dream induced by a Maleficent‐like evil genius. The problem in the present context is that the possibility of a dream‐inducing Maleficent‐like evil genius guarantees that how things appear would be no different, whether she (...) is dreaming or not. But maybe there is a difference: does it not appear to her that there is a difference between dreaming and wakefulness? The very fact that she is aware of such a distinction at all suggests the distinction is real. People prefer a real life over an experientially identical dream life, or even a more pleasurable dream life, because there is more to life than just experience. (shrink)
