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)

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.

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?

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)

In terms of validity in Kripke frames, a modal formula expresses a universal monadic second-order condition. Those modal formulae which are equivalent to first-order conditions are called \emph{elementary}. Modal formulae which have a certain persistence property which implies their validity in all canonical frames of modal logics axiomatized with them, and therefore their completeness, are called \emph{canonical}. This is a survey of a recent and ongoing study of the class of elementary and canonical modal formulae. We summarize main ideas and (...) results, and outline further research perspectives. (shrink)

In this paper, we outline a theory of the nature of self-directed agents. What is distinctive about self-directed agents is their ability to anticipate interaction processes and to evaluate their performance, and thus their sensitivity to context. They can improve performance relative to goals, and can, in certain instances, construct new goals. We contrast self-directedness with reactive action processes that are not modifiable by the agent, though they may be modified by supra-agent processes such as populational adaptation or external design.

Unlike old soldiers, the rhetoric of the great neither dies nor fades away. And so Hume's celebrated ‘is-ought’ passage still provokes debate.Hume was worried about the relation between ought statements and those supporting them: between ‘tolerence brings peace’ or ‘is God's will’, and ‘so one ought to be tolerant’. He denies the deducibility of the latter from the former, as the ‘ought’ expresses ‘a new relation or affirmation’, ‘entirely different from the others’. And this is commonly taken as saying that (...) the ought statement is ‘different’ and non-deducible, because it is no longer a ‘purely factual statement’, to wit one that makes another ordinarily testable truth claim.However, recent criticism, by W. D. Hudson and others, points out that Hume says other things seemingly inconsistent with this. In the passage, he mentions ‘ought’ and ‘virtue’ interchangeably, and ‘tolerance is virtuous’ as in the same boat as ‘one ought to be tolerant’. But, also, he treats the virtue of an action as sensibly discernible by the approbation which it evokes, and takes us to mean by a virtuous action that we will approve of it on contemplation.

Keith Hossack's thesis is that knowledge is a conceptually primitive and metaphysically fundamental relation between a mind and a fact. He argues that in terms of the simple relation of knowledge we can analyze central notions of epistemology , of semantics , of modality and a priori knowledge , of psychology , and of linguistics . He does so in a framework that includes a fairly rich faculty psychology and that stresses causation: knowledge can be caused by belief, but because (...) knowledge is simple, it is not any kind of belief. He regards his enterprise as metaphysics, and he proceeds in a rather grand manner. The beginning of his Preface might remind one of the opening paragraphs of Leibniz's The Monadology.If knowledge is a simple relation between minds and facts, then we want to know a bit about facts. Hossack takes facts to consist in universals being instantiated among things. He favours a view of universals as respects in which things resemble each other , but his theory is at least officially silent about which universals exist, leaving that as a matter for scientific inquiry . But he takes metaphysics to be a science . Here he is being coy, and it is worth making out how. Hossack uses multigrade relations; these are relations of no fixed polyadicity that for any natural number n may be instantiated by n things. Vectors are bearers of such relations. The relation among working men of uniting to form a union is a multigrade relation, and the founders of the International Workers of the World are a vector bearing this relation. (shrink)

Examines the relations between logic and philosophy over the last 150 years. Logic underwent a major renaissance beginning in the nineteenth century. Cantor almost tamed the infinite, and Frege aimed to undercut Kant by reducing mathematics to logic. These achievements were threatened by the paradoxes, like Russell's. This ferment generated excellent philosophy by excellent philosophers up to World War II. This book provides a selective, critical history of the collaboration between logic and philosophy during this period. After World War II, (...) mathematical logic became a recognized subdiscipline in mathematics departments, and consequently but unfortunately philosophers have lost touch with its monuments. This book aims to make four of them more accessible to philosophers, making available the tools necessary for modern scholars of philosophy to renew a productive dialogue between logic and philosophy.

This is the third of five chapters on good, and inquires into what kinds of things are intrinsically good. The first thing claimed as intrinsically good is virtuous disposition and action; the second is pleasure in itself. These two approaches are briefly analysed, with the goodness or badness of pleasure given particular attention. Ross concludes that four things can be seen to be intrinsically good—virtue, pleasure, the allocation of pleasure to the virtuous, and knowledge. He is unable to discover anything (...) that is intrinsically good that is not either one or a combination of these. (shrink)

A significant share of the U.S. federal R&D budget is devoted to large-scale, complex technological systems commonly referred to as "big science. " Over the last two decades, these systems have continued to grow in size, complexity, development time, and cost. At the same time, political changes in the United States, particularly the concern over government spending and the federal budget deficit, have made it more difficult for proponents to secure and preserve support for these programs over their lifetimes. Using (...) the U.S. space shuttle and space station programs as examples, the article shows that the political requirements for obtaining approval and funding for large and expensive research and development projects create conditions that reduce the likelihood that they will succeed technologically. The problems of technology-based projects like those of the U.S. space program are in fact deeply rooted in the American political process itself. (shrink)

Purpose: The aim of this research was to test whether Hong Kong science students would prefer a learning environment based on critical constructivism and whether a closer preferred-actual fit to such an environment would be associated with better learning outcomes. Method: The participants were 149 Hong Kong secondary school Chemistry students aged 16--19 years. They completed actual and preferred forms of a Chinese version of the Constructivist Learning Environment Survey and measures of self-efficacy and intrinsic value of their Chemistry course. (...) Their Chemistry examination scores were also obtained at the end of the course. Findings: Analysis showed that these students would prefer their Chemistry classrooms to be more personally relevant, to allow students more say and to share more control, and to encourage more negotiation with their teacher. Regression surface analysis showed that congruence of person environment fit did not influence examination results but was associated with greater valuing of the course and higher student self-efficacy. Research implications: Further research with a wider sampling from Hong Kong and elsewhere and focusing on other subject areas will be necessary to assess the generalizability of these findings. Practical implications: It seems that educational reforms based on critical constructivist principles may be of value in non-Western contexts. Original value: Educational reforms in Hong Kong and elsewhere currently are based on traditional constructivist principles. But this is the first research to support a more radical approach in what is usually regarded as a relatively conservative Asian educational context. (shrink)

Objectives The objectives of the study are to understand the current practice of informed consent in medical research in public hospitals in Shanghai, and to share our views with other countries, especially developing countries. Methods In the study, 145 consent forms (CFs) of the selected research projects in eight public hospitals with ethics committees in Shanghai were audited, and the principle investigators (PIs) of these research projects and 40 student subjects who had participated in clinical drug tests were surveyed by (...) questionnaires. Results The CFs of medical researches in public hospitals with ethics committees in Shanghai were generally acceptable. However, there were some defects in the CFs. Although most of the surveyed PIs had correct recognition of informed consent, some processes of informed consent were not in accordance with generally accepted requirements. A large number of the PIs considered the greatest difficulty with informal consent was lack of correct recognition of subjects or legally authorised representatives on medical research. Discussion Informed consent in medical research should consider the research ethics, the background of potential subjects, the local resources and culture of medical research. In addition, special protection is needed for student subjects in informed consent as well as efforts for building and restoring the public's trust in biomedical research. Conclusion The informed consent in Shanghai's public hospitals with ethics committees was generally acceptable and the achievement of adequate informed consent is influenced by many factors. (shrink)
