Measuring neuronal activity with electrophysiological methods may be useful in detecting neurological dysfunctions, such as mild traumatic brain injury (mTBI). This approach may be particularly valuable for rapid detection in at-risk populations including military service members and athletes. Electrophysiological methods, such as quantitative electroencephalography (qEEG) and recording event-related potentials (ERPs) may be promising; however, the field is nascent and significant controversy exists on the efficacy and accuracy of the approaches as diagnostic tools. For example, the specific measures derived from an (...) electroencephalogram (EEG) that are most suitable as markers of dysfunction have not been clearly established. A study was conducted to summarize and evaluate the statistical rigor of evidence on the overall utility of qEEG as an mTBI detection tool. The analysis evaluated qEEG measures/parameters that may be most suitable as fieldable diagnostic tools, identified other types of EEG measures and analysis methods of promise, recommended specific measures and analysis methods for further development as mTBI detection tools, identified research gaps in the field, and recommended future research and development thrust areas. The qEEG study group formed the following conclusions: 1. Individual qEEG measures provide limited diagnostic utility for mTBI. However, many measures can be important features of qEEG discriminant functions, which do show significant promise as mTBI detection tools. 2. ERPs offer utility in mTBI detection. In fact, evidence indicates that ERPs can identify abnormalities in cases where EEGs alone are nondisclosing. 3. The standard mathematical procedures used in the characterization of mTBI EEGs should be expanded to incorporate newer methods of analysis including nonlinear dynamical analysis, complexity measures, analysis of causal interactions, graph theory and information dynamics. 4. and 5. are too long to include here.

Das »Richtige und das Gute« (1930), das ethische Hauptwerk W. D. Ross’, enthält eine Vielzahl wichtiger moralphilosophischer Thesen und Argumente, die bis in die Gegenwart kontrovers diskutiert werden. Im Mittelpunkt steht seine pluralistische Deontologie, der zufolge sich die richtige Handlung aus einer Abwägung der in der jeweiligen Situation relevanten und unableitbaren Prima-facie-Pflichten ergibt, von denen nur ein Teil auf die Optimierung der Handlungsfolgen bezogen ist. Diese Deontologie wurde zu einem modernen Klassiker unter den normativen ethischen Theorien. Darüber hinaus stellt Ross’ (...) These, dass moralische Intuitionen eine Quelle selbstevidenten Wissens sein können, einen wichtigen Referenzpunkt in Debatten um den erkenntnistheoretischen Fundamentalismus dar. Auch für die Handlungstheorie liefert Ross einflussreiche Argumente, wenn er die Ansicht vertritt, dass Pflichten nie ein bestimmtes Motiv des Handelnden zum Gegenstand haben können. Eine zentrale Stellung nimmt für Ross die Güterlehre ein, in welcher er von vier Grundgütern, Tugend, Wissen, Lust und Gerechtigkeit, ausgeht. Wurde Ross in den ersten Jahrzehnten des 20. Jahrhunderts im damaligen Großbritannien als ein herausragender Ethiker – einer der bedeutendsten des Jahrhunderts, auf Augenhöhe mit G.E. Moore – angesehen, wandelte sich das Meinungsbild in den folgenden Jahrzehnten unter dem Einfluss besonders des Logischen Positivismus und der Philosophie Wittgensteins. In den letzten Jahrzehnten ist jedoch wieder ein wachsendes Interesse an Ross’ Ethik festzustellen. Dabei wird »Das Richtige und das Gute« bisweilen sogar mit der »Nikomachischen Ethik«, Kants »Grundlegung« und Humes »Untersuchung über die Prinzipien der Moral« verglichen. (shrink)

The Right and the Good, a classic of twentieth-century philosophy by the eminent scholar Sir David Ross, is now presented in a new edition with a substantial introduction by Philip Stratton-Lake, a leading expert on Ross. Ross's book is the pinnacle of ethical intuitionism, which was the dominant moral theory in British philosophy for much of the nineteenth and early twentieth century. Intuitionism is now enjoying a considerable revival, and Stratton-Lake provides the context for a proper understanding of Ross's great (...) work today. (shrink)

It is sometimes suggested that the logic of religious language differs from other kinds of language. Or it is said that each ‘language-game’ has its own ‘logic’ and that, whatever usual language-games are played in the context of religion, there is something that could be called the ‘religious language-game’ which does not correspond to any other and, therefore, has its own peculiar logic. In either case, religious people are urged to make clear what this logic is, so that their utterances (...) may be understood and evaluated. (shrink)

What connexion is there between factual statements concerning God or man and moral judgments? That is the question which occasions this paper. Not long ago moral philosophers were wont to say that there is a logical gap between the two sorts of utterance to which I have just referred: that nothing follows in terms of moral value from a statement of fact, no ‘ought’ from any ‘is’. They recognised only one restriction on what may be said in terms of ‘ought’ (...) by what has been said in terms of ‘is’, namely that ‘ought’ implies ‘can’. It is manifest nonsense to say that anyone ought to do what he cannot do. But, this apart, they thought it possible without contradiction or anomaly to hold any conceivable factual belief and at the same time subscribe to any conceivable moral judgment. They would have held that it makes perfectly good sense to say, for example, ‘This is God’s will but it ought not to be done’ or ‘Men are not pigs but a good man will live like a pig’. Bizarre such judgments may be, they would have said, but nonsensical they are not. They conceived it to be their main business, as moral philosophers, to erect warning notices along the edge of the is-ought gap so that contemporary moralists would not fall headlong into it as so many of their predecessors, in less enlightened ages, had done.

At the beginning of his book, Principles of Christian Theology, John Macquarrie says that theology ‘implicitly claims to have its place in the total intellectual endeavour of mankind’. The question I want to discuss is this: in what terms, if any, can that claim be justified?

I want to put forward a certain view of the logical foundation of religious belief. It is, in a sentence, the view that religious belief is constituted by the concept of god. This view will be discussed under three headings. First, I shall explain as clearly as I can what I mean by it. Secondly, I shall indicate what seem to me to be interesting parallels, both with regard to universes of discourse in general and to religious belief in particular, (...) between my idea of a constitutive concept and Wittgenstein's ideas of a fundamental proposition and a religious ‘picture’. Thirdly, I shall try to substantiate the view I take of the logical foundation of religious belief by rebutting three conceivable objections to it: namely, that it rests on an illegitimate craving for generality, that it is at variance with common usage, and that it consigns religious belief to an intellectual ghetto.

There has been a good deal of interest in recent years in what Franz Brentano had to say about the notion of ‘intentional objects’ and about intentionality as a criterion of the mental. There has been less interest in his classification of mental phenomena. In his Psychology from an Empirical Standpoint Brentano asserts and argues for the thesis that mental phenomena can be classified in terms of three kinds of mental act or activity, all of which are directed towards an (...) immanent object. These are, respectively, presentation, judgment and what he calls the phenomena of love and hate. Once again, less interest has been shown in what he has to say about the last of these three than in what he says about the others. I wish to take Brentano's views as the point of departure for a discussion of love and hate, since these notions seem to me to have a good deal of philosophical interest, for at least two main reasons. First, I have recently had some concern with the part that personal relations play in our understanding of others and of ourselves, and love and hate seem to be very important elements in such relations. Second, love and hate have long seemed to me to provide important counter-examples to some prevalent philosophical theories about the emotions. I shall take this issue first. (shrink)

One would hardly be a human being if the good of others, or of society at large, could not weigh with one as a cogent reason for doing what will promote goodness. So one has not fully learned about living like a rational and moral being unless one has learned to appreciate that one ought to do things out of regard for others, and not only out of regard for oneself. In the first place, not everything done for oneself is (...) done for reasons of prudence. That one ought to insure one's house, save for one's old age, not put all one's money into one venture, are precepts of prudence. But it is not a precept of prudence, though it may be a good precept that someone ought to undergo a dangerous operation as a long shot to restoring his health rather than linger under a disability forever after.

This study is an unusual contribution to the philosophy of mind in that it argues for the sometimes unfashionable view of dualism: that mind and matter are distinct and separate entities as Descartes believed. The author takes as his point of departure the imaginative hypothesis of disembodiment, which establishes the possibility of the mind's being a quite non-material thing. There are clear casual correlations between what is physical and what is mental, and the most serious issue confronting dualism since Descartes (...) has been how such an interaction is possible. Dr Hart sets out to answer this question by showing that the issue is as much about the nature of causation as it is about the natures of mind and matter. (shrink)

There are substantial data establishing that surrogates are often mistaken in predicting what treatments incompetent patients would have wanted and that supplements such as advance directives have not resulted in significant improvements. Rid and Wendler’s Patient Preference Predictor (PPP) proposal will attempt to gather data about what similar patients would prefer in a variety of treatment choices. It accepts the usual goal of patient autonomy and the Substituted Judgment principle for surrogate decisions. I provide reasons for questioning sole reliance on (...) autonomy when surrogates, not patients, are deciding and for giving some independent weight to patient well-being. Moreover, that family members, typical surrogates, will know best what the patient if incompetent would have wanted is not the only reason why they are chosen. The more pressing problem is that the PPP would fail to remove the more serious mistakes that empirical psychology over the last few decades has shown to infect such decision making. (shrink)

Social scientists could learn some useful things from philosophy. Here I shall discuss what I take to be one such thing: a better understanding of the concept of utility. There are several reasons why a better understanding may be useful. First, this concept is commonly found in the writings of social scientists, especially economists. Second, utility is the main ingredient in utilitarianism, a perspective on morality that, traditionally, has been very influential among social scientists. Third, and most important, with a (...) better understanding of utility comes, as I shall try to show here, a better understanding of “personal welfare”. or, in other words, of what may be said to be in people's best interests. Such an understanding is useful to social scientists and philosophers alike, whether for utilitarian purposes or not. (shrink)

A model of spontaneous collapse of fermionic degrees of freedom in a quantum field is presented which has the advantages that it explicitly maintains energy conservation and gives results in agreement with an existing numerical method for calculating quantum state evolution, namely the quantum trajectories model.
