Gottlob Frege (1848-1925) was unquestionably one of the most important philosophers of all time. He trained as a mathematician, and his work in philosophy started as an attempt to provide an explanation of the truths of arithmetic, but in the course of this attempt he not only founded modern logic but also had to address fundamental questions in the philosophy of language and philosophical logic. Frege is generally seen (along with Russell and Wittgenstein) as one of the fathers of the (...) analytic method, which dominated philosophy in English-speaking countries for most of the twentieth century. His work is studied today not just for its historical importance but also because many of his ideas are still seen as relevant to current debates in the philosophies of logic, language, mathematics and the mind. The Cambridge Companion to Frege provides a route into this lively area of research. (shrink)
Continuous recordings of brain electrical activity were obtained from a group of 176 patients throughout surgical procedures using general anesthesia. Artifact-free data from the 19 electrodes of the International 10/20 System were subjected to quantitative analysis of the electroencephalogram (QEEG). Induction was variously accomplished with etomidate, propofol or thiopental. Anesthesia was maintained throughout the procedures by isoflurane, desflurane or sevoflurane (N = 68), total intravenous anesthesia using propofol (N = 49), or nitrous oxide plus narcotics (N = 59). A set (...) of QEEG measures were found which reversibly displayed high heterogeneity of variance between four states as follows: (1) during induction; (2) just after loss of consciousness (LOC); (3) just before return of consciousness (ROC); (4) just after ROC. Homogeneity of variance across all agents within states was found. Topographic statistical probability images were compared between states. At LOC, power increased in all frequency bands in the power spectrum with the exception of a decrease in gamma activity, and there was a marked anteriorization of power. Additionally, a significant change occurred in hemispheric relationships, with prefrontal and frontal regions of each hemisphere becoming more closely coupled, and anterior and posterior regions on each hemisphere, as well as homologous regions between the two hemispheres, uncoupling. All of these changes reversed upon ROC. Variable resolution electromagnetic tomography (VARETA) was performed to localize salient features of power anteriorization in three dimensions. A common set of neuroanatomical regions appeared to be the locus of the most probable generators of the observed EEG changes. (shrink)
If I lose my key in Canada, for instance, and I search for it in the United Kingdom, how long will I take to find it? This paper argues that problems in education are caused by non-professional teachers who are employed when trained teachers move in search of promotion friendly activities or financially rewarding duties. This shift of focus means that policy makers in education act without adequate professional guidance. The problems in education, therefore, result from demands made on mainstream (...) education based on misconceptions about what education can offer. It is argued that the implementation of e-learning in education faces the risk of developing on the basis of unproven theories. This scenario increasingly sees the replacement of formal education activities in institutions of learning with non-formal and informal education practices. Given that the contents and influences of non-formal and informal education are not under the control of the teacher, the experiences that learners bring to education settings are increasingly difficult to manage. The paper proposes that by integrating e-learning in teacher education and rewarding 'good teaching', there is a potential for a successful e-learning revolution in education. (shrink)
Voyeurism seems creepy. This paper considers whether these feelings are well-founded. It identifies a variety of ethically troubling features, including harmful consequences, deceit, and the violation of various religious, legal, and conventional norms. Voyeurism is something of a moral misdemeanor that seems worrisome when associated with these other failings. However, because voyeurism remains troubling even in the absence of harm or deceit, we must pay special attention to the ways complex social conventions can be used to show disrespect for others. (...) The discussion centers on the famous case of Lady Godiva and Peeping Tom, but much of the analysis applies to voyeurism more generally. (shrink)
Tom Kelly argues that instrumentalist aeeounts of epistemie rationality fail beeause what a person has reason to believe does not depend upon the eontent of his or her goals. However, his argument fails to distinguish questions about what the evidence supports from questions about what a person ought to believe. Once these are distinguished, the instrumentalist ean avoid Kelly’s objeetions. The paperconcludes by sketehing what I take to be the most defensible version of the instrumentalist view.
A recently published book, 'The Economics of Health Reconsidered' by Tom Rice, provides a strong critique of the role of markets in health care. Many of the issues of 'market failure' raised by Rice, however, have been, to varying extents, recognised previously in the health economics literature (at least outside the U.S.). What perhaps sets Rice's book apart from previous attempts to document such issues is its elegance and the methodical manner in which this critique is delivered. Significantly the critique (...) is based solely on conventional economic arguments. There has, however, been an emerging strand of the health economics literature not acknowledged in Rice's book which has approached some of these issues of market failure from a different perspective. Notably this research has involved, in part, borrowing from the ideas and methodological traditions of other disciplines. The emphasis in this work has been to expand the scope and the concerns of economic analysis in health care. (shrink)
Since its publication in 1976, Tom Paine and Revolutionary America has been recognized as a classic study of the career of the foremost political pamphleteer of the Age of Revolution, and a model of how to integrate the political, intellectual, and social history of the struggle for American independence. Foner skillfully brings together an account of Paine's remarkable career with a careful examination of the social worlds within which he operated, in Great Britain, France, and especially the United States. He (...) explores Paine's political and social ideas and the way he popularized them by pioneering a new form of political writing, using simple, direct language and addressing himself to a reading public far broader than previous writers had commanded. He shows which of Paine's views remained essentially fixed throughout his career, while directing attention to the ways his stance on social questions evolved under the pressure of events. This enduring work makes clear the tremendous impact Paine's writing exerted on the American Revolution, and suggests why he failed to have a similar impact during his career in revolutionary France. And it offers new insights into the nature and internal tensions of the republican outlook that helped to shape the Revolution. In a new preface, Foner discusses the origins of this book and the influences of the 1960s and 1970s on its writing. He also looks at how Paine has been adopted by scholars and politicians of many stripes, and has even been called the patron saint of the Internet. (shrink)
Tom Regan (this issue) criticizes my thesis that obligation toward the environment is grounded in a world view and thereby has a moral overridingness which mere interests and desires do not have. He holds that my approach is too subjectivistic. I counter, first, by explaining that phenomenology, which I use in my analysis of moral obligation, is not subjectivistic in the way emotivism or prescriptivism inethics is subjectivistic. Second, I argue that world views are products of learning and experience of (...) one shared world, that most world views share large areas of agreement, and that they can be argued for and criticized.

This is an extremely thorough revision of the leading textbook of bioethics. The authors have made many improvements in style, organization, argument and content. These changes reflect advances in the bioethics literature over the past five years. The most dramatic expansions of the text are in the comprehensiveness with which the authors treat different currents in ethical theory and the greater breadth and depth of their discussion of public policy and public health issues. In every chapter, readers will find new (...) material and refinements of old discussions. This is evident in the many new sections on topics like communitarianism, ethics of care, relationship-based accounts, casuistry, case-based reasoning, principle-based common-morality theories, the justification of assistance in dying, rationing through priorities in the health care budget, and virtues in professional roles. The most extensive revisions are in chapters 1, 2 and 8. (shrink)
Abstract I argue against the two most influential readings of Frege's methodology in the philosophy of logic. Dummett's ?semanticist? reading sees Frege as taking notions associated with semantical content?and in particular, the semantical notion of truth?as primitive and as intelligible independently of their connection to the activity of judgment, inference, and assertion. Against this, the ?pragmaticist? reading proposed by Brandom and Ricketts sees Frege as beginning instead from the independent and intuitive grasp that we allegedly have on the latter (...) activity and only then moving on to explain semantical notions in terms of the nature of such acts. Against both readings, I argue, first, that Frege gives clear indication that he takes semantical and pragmatical notions to be equally primitive, such that he would reject the idea that either sort of notion could function as the base for a non-circular explanation of the other. I argue, secondly, that Frege's own method for conveying the significance of these primitive notions?an activity that Frege calls ?elucidation??is, in fact, explicitly circular in nature. Because of this, I conclude that Frege should be read instead as conceiving of our grasp of the semantical and pragmatical dimensions of logic as far more of a holistic enterprise than either reading suggests.

In this article, I seek to make sense of the oft-invoked idea of 'public emergency' and of some of its (supposedly) radical moral implications. I challenge controversial claims by Tom Sorell, Michael Walzer, and Giorgio Agamben, and argue for a more discriminating understanding of the category and its moral force.
Wesley Salmon and John Earman have presented influential Bayesian reconstructions of Thomas Kuhn’s account of theory-change. In this paper I argue that all attempts to give a Bayesian reading of Kuhn’s philosophy of science are fundamentally misguided due to the fact that Bayesian confirmation theory is in fact inconsistent with Kuhn’s account. The reasons for this inconsistency are traced to the role the concept of incommensurability plays with reference to the ‘observational vocabulary’ within Kuhn’s picture of scientific theories. The upshot (...) of the discussion is that it is impossible to integrate both Kuhn’s claims and Bayesianism within a coherent account of theory-change. (shrink)
