Philosophy in Africa has for more than a decade now been dominated by the discussion of one compound question, namely, is there an African philosophy, and if there is, what is it? The first part of the question has generally been unhesitatingly answered in the affirmative. Dispute has been primarily over the second part of the question as various specimens of African philosophy presented do not seem to pass muster. Those of us who refuse to accept certain specimens as philosophy (...) have generally been rather illogically said also to deny an affirmative answer to the first part of the question. In a paper presented at the International Symposium in Memory of Dr William Amo, the Ghanaian philosopher who taught in German universities in the early part of the eighteenth century, Professor Odera Oruka identified four trends, perhaps more appropriately approaches, in current African philosophy.

Attitudes towards active voluntary euthanasia (AVE) and physician-assisted suicide (PAS) among 1,238 doctors on the medical register of New South Wales varied significantly with self-identified religious affiliation. More doctors without formal religious affiliation ('non-theists') were sympathetic to AVE, and acknowledged that they had practised AVE, than were doctors who gave any religious affiliation ('theists'). Of those identifying with a religion, those who reported a Protestant affiliation were intermediate in their attitudes and practices between the agnostic/atheist and the Catholic groups. Catholics (...) recorded attitudes most opposed to AVE, but even so, 18 per cent of Catholic medical respondents who had been so requested, recorded that they had taken active steps to bring about the death of patients.

We investigate the Sp(2, R) model for light and heavy nuclei and compare it to recent applications of the Sp(6, R) model. The same Hamiltonian is used and the basis states will have good angular momentum. We not only confirm that the restricted space of the Sp(6, R) model gives the dominant contribution but also that there is no practical difference from the Sp(6, R) model calculations. The Sp(2, R) model is then applied to the chain of Ba-isotopes which show, (...) according to a recent application of the geometrical model, a dominant prolate behavior with an important γ-unstable component. They represent limiting cases where the Sp(2, R) model can be put to an extreme test. (shrink)

In his book, The Principles of Mathematics , the young Bertrand Russell abandoned the common-sense notion that the whole must be greater than its part, and argued that wholes and their parts can be similar, e.g. where both are infinite series, the one being a sub-series of the other. He also rejected the popular view that the idea of an infinite number is self-contradictory, and that an infinite set or collection is an impossibility. In this paper, I intend to re-examine (...) Russell's wisdom in doing both these things, and see if it might not have made more sense, and caused his enterprise fewer problems, if he had simply stuck to our commonplace ideas. To this end, I shall also be considering his treatment of certain paradoxes that he claims can only be resolved by the abandonment of the above notions, as well as certain others which his theories appear to have generated.

In a recent paper in this journal, Dagsvik derives the class of independent random utility representations that are “equivalent” to the independence-from-irrelevant-alternatives assumption by Luce. In this short note, we clarify the relations between this paper by Dagsvik, and a paper in Lindberg’s 2012 thesis.

The prefrontal cortex is widely believed to play an important role in facilitating people's ability to switch performance between different tasks. We present a biologically‐based computational model of prefrontal cortex (PFC) that explains its role in task switching in terms of the greater flexibility conferred by activation‐based working memory representations in PFC, as compared with more slowly adapting weight‐based memory mechanisms. Specifically we show that PFC representations can be rapidly updated when a task switches via a dynamic gating mechanism based (...) on a temporal‐differences reward‐prediction learning mechanism. Unlike prior models of this type, the present model develops all of its internal representations via learning mechanisms as shaped by the demands of continuous periodic task switching. This advance opens up a new domain of research into the interactions between working memory task demands and the representations that develop to meet them. Results on a version of the Wisconsin card sorting task are presented for the full model and a number of comparison networks that test the importance of various model features. Furthermore, we show that a lesioned model produces perseverative errors like those seen in frontal patients. (shrink)

Mark Morford provides a lively, succinct, and comprehensive survey of the philosophers of the Roman World, from Cato the Censor in 155 BCE to the death of Marcus Aurelius in 180 CE. These men were asking philosophical questions whose answers had practical effects on people's lives in antiquity--and still do today--yet this is an era of philosophy somewhat neglected in recent decades. Morford puts this right by discussing the writings and ideas of numerous famous and lesser-known figures. Using extensive and (...) fully-translated quotations from their works, he illuminates each of the philosopher's meanings within the historical, political, and cultural contexts of their day. This book serves as the ideal introduction to the newcomer to Roman philosophy. (shrink)

The philosophers of the Roman world were asking questions whose answers had practical effects on people's lives in antiquity, and which still influence our thinking to this day. In spite of being neglected in the modern era, this important age of philosophical thought is now undergoing a revival of interest. Mark Morford's lively survey makes these recent scholarly developments accessible to a wide audience, examining the writings and ideas of both famous and lesser known figures - from Cato the Censor (...) in 155 BCE to Marcus Aurelius in 180 CE. Based around extensive and fully translated quotations from the philosophical texts of the era, full consideration is given throughout to historical, political and cultural context. (shrink)

ABSTRACTDiagnostic self‐testing devices are being developed for many illnesses, chronic diseases and infections. These will be used in hospitals, at point‐of‐care facilities and at home. Designed to allow earlier detection of diseases, self‐testing diagnostic devices may improve disease prevention, slow the progression of disease and facilitate better treatment outcomes. These devices have the potential to benefit both the individual and society by enabling individuals to take a more proactive role in the maintenance of their health and by helping society improve (...) health and reduce health costs. However, the full implications of future home‐based diagnostic technology for individuals and society remain unclear due to their novelty.We argue that the development of diagnostic tools, especially for home use, will heighten a number of ethical challenges. This paper will explore some of the ethical implications of home‐based self‐testing diagnostic devices for the autonomous and relational dimensions of the person. This will be facilitated by examining the impact of diagnostic devices for individual autonomy, for the delivery of accurate diagnosis and for the personal significance of the information for the user. The latter will be examined using Charles Taylor's view of personhood and his emphasis on human agency and interpretation.While the ethical issues are not necessarily new, the development of home‐based self‐testing diagnostic devices will make issues regarding autonomy, accuracy of information and personal significance more and more demanding. This will be the case particularly when an individual's autonomous choices come into conflict with the person's relational responsibilities. (shrink)

Philosophical reflections on the environment began with early philosophers' invocation of a cosmology that mixed natural and supernatural phenomena. Today, the central philosophical problem posed by the environment involves not what it can teach us about ourselves and our place in the cosmic order but rather how we can understand its workings in order to make better decisions about our own conduct regarding it. The resulting inquiry spans different areas of contemporary philosophy, many of which are represented by the fifteen (...) original essays in this volume. The contributors first consider conceptual problems generated by rapid advances in biology and ecology, examining such topics as ecological communities, adaptation, and scientific consensus. The contributors then turn to epistemic and axiological issues, first considering philosophical aspects of environmental decision making and then assessing particular environmental policies, including reparations, remediation, and nuclear power, from a normative perspective.
