We discuss arguments against the thesis that the world itself can be vague. The first section of the paper distinguishes dialectically effective from ineffective arguments against metaphysical vagueness. The second section constructs an argument against metaphysical vagueness that promises to be of the dialectically effective sort: an argument against objects with vague parts. Firstly, cases of vague parthood commit one to cases of vague identity. But we argue that Evans' famous argument against will not on its own enable one to (...) complete the reductio in the present context. We provide a metaphysical premise that would complete the reductio, but note that it seems deniable. We conclude by drawing general morals from our case study. (shrink)

In spite of the seeming heterogeneity of topics in its title - Revolutions, Systems, and Theories - this volume purports to be something more than a random collection of Essays in Political Philosophy. The Colloquium of the Philosophy Department of the University of Western Ontario (29-31 Octo­ ber, 1971) at which initial versions of the first eight papers were delivered was entitled 'Political Theory'; and while the organizers anticipated and indeed welcomed topicality in the issues accorded priority arid in the (...) empirical evidence invoked, they were also hoping for a reasonably comprehensive explorat ion of some of the central issues of political philosophy. For this reason it was quickly decided that in such a field a philosophical focus on clarification of ordering concepts required the suppIement - and test - of researches into more particular subject maUers by social scientists. Thus, to speak in general terms (where the specializatlons and their taxonomies multi­ ply fissiparously!), contributors include political scientists, economists and sociologists (Barnard, Baston, Tullock, Rapoport) as well as philosophers (Scriven, Morgenbesser, Braybrooke, TayIor), and juxtaposed as proponents and commentators ·to generate exchanges across disciplinary frontiers. While the five additional invited papers are alI by professional philosophers, they extend the original Colloquium either by continuing controversy on its funda­ mental issues (e. g., Rubinoff, Nielsen, Roy) or by their continued explorations in what are acknowledged to be boundary areas (e. g., Schick, Wartofsky). The greatest topical emphasis is that on revolution. (shrink)

I argue that the current view (as held by, eg., Warnock, Anscombe and Stenius) of Wittgenstein's theory of language in the Tractates is mistaken. This view maintains that Wittgenstein's theory is one of 'isomorphism'; that, roughly, a sentence has meaning in virtue of its being a facsimile of a fact or possible fact. But a detailed study of significant passages in the Tractattis shows that Wittgenstein held no such view. His use of important terms, such as Salz, Bild, Sachverhalt, Tatsache (...) , etc., has been crucially misunderstood. There is no isomorphism. The theory is not about sentences at all, but about talking sense. (shrink)

We used computer simulations to study the possible role of the dispersion of cellular coupling, refractoriness or both, in the mechanisms underlying cardiac arrhythmias. Local ischemia was first assumed to induce cell to cell dispersion of the coupling resistance (Case 1), refractory period (Case 2), or both of them (Case 3). Our numerical experiments based on the van Capelle and Durrer model showed that vortices could not be induced by cell to cell variations. With cellular properties dispersed in a patchy (...) way within the ischemic zone, a single activation wave could give rise to abnormal activities. This demonstrates the stability of the wave front under small inhomogeneities. Probabilities of reentry, estimated for the three cases cited above showed that a severe alteration of the coupling resistance may be an important factor in the genesis of reentry. Moreover, use of isochronal maps revealed that vortices were both stable and sustained with an alteration of the coupling alone or combined with a reduction of the action potential duration. Conversely, simulations with reduction of the refractoriness alone, inducing only transient patterns, could exhibit functionally determined reentries. (shrink)

An alleged moral right to informational privacy assumes that we should have control over information about ourselves. What is the philosophical justification for this control? I think that one prevalent answer to this question—an answer that has to do with the justification of negative rights generally—will not do.

In Ethics and the Limits of Philosophy, Bernard Williams is rather severe on what he thinks of as an ethics of obligation. He has in mind by this Kant and W. D. Ross. For many, obligation seems the very core of ethics and the moral realm, and lives more generally are seen through the prism of this notion. This, according to Williams, flattens out our lives and moral experience and fails to take into account things which are obviously important to (...) our lives. Once we take these things into account, what do we do if they come into conflict with some of our moral obligations, as Williams, in his earlier writings on moral luck, thought to be the case. I want here to explore some of these ideas, in a way that I think harmonious with Williams's general bent though not one that I intend as in any way detailed exegesis of Williams's work. (shrink)

Mr Olding's recent attack on my exposition of the argument from design gives me an opportunity to defend the central theses of my original article. My article pointed out that there were arguments from design of two types—those which take as their premisses regularities of copresence and those which take as their premisses regularities of succession. I sought to defend an argument of the second type. One merit of such an argument is that there is no doubt about the truth (...) of its premisses. Almost all objects in the world behave in a highly regular way describable by scientific laws. Further, any scientific explanation of such a regularity must invoke some more general regularity. The most general regularities of all are, as such, scientifically inexplicable. The question arises whether there is a possible explanation of another kind which can be provided for them, and whether their occurrence gives any or much support to that explanation. I urged that we do explain some phenomena by explanation of an entirely different kind from the scientific. We explain states of affairs by the action of agents who bring them about intentionally of their own choice. Regularities of succession, as well as other phenomena may be explained in this way. Explanation of this kind I will term intentional explanation. Intentional explanation of some phenomenon E consists in adducing an agent A who brought E about of his own choice and a further end G which, he believed, would be forwarded by the production of E.

On what grounds will the rational man become a Christian? It is often assumed by many, especially non-Christians, that he will become a Christian if and only if he judges that the evidence available to him shows that it is more likely than not that the Christian theological system is true, that, in mathematical terms, on the evidence available to him, the probability of its truth is greater than half. It is the purpose of this paper to investigate whether or (...) not this is a necessary and sufficient condition for the rational man to adopt Christianity. (shrink)

In this article we show that it is possible to completely classify the degrees of r.e. bases of r.e. vector spaces in terms of weak truth table degrees. The ideas extend to classify the degrees of complements and splittings. Several ramifications of the classification are discussed, together with an analysis of the structure of the degrees of pairs of r.e. summands of r.e. spaces.

Background Clinical papers so flawed that they are eventually retracted may put patients at risk. Patient risk could arise in a retracted primary study or in any secondary study that draws ideas or inspiration from a primary study. Methods To determine how many patients were put at risk, we evaluated 788 retracted English-language papers published from 2000 to 2010, describing new research with humans or freshly derived human material. These primary papers—together with all secondary studies citing them—were evaluated using ISI (...) Web of Knowledge. Excluded from study were 468 basic science papers not studying fresh human material; 88 reviews presenting older data; 22 case reports; 7 papers retracted for journal error and 23 papers unavailable on Web of Knowledge. Overall, 180 retracted primary papers (22.8%) met the inclusion criteria. Subjects enrolled and patients treated in 180 primary studies and 851 secondary studies were combined. Results Retracted papers were cited over 5000 times, with 93% of citations being research related, suggesting that ideas promulgated in retracted papers can influence subsequent research. Over 28 000 subjects were enrolled—and 9189 patients were treated—in 180 retracted primary studies. Over 400 000 subjects were enrolled—and 70 501 patients were treated—in 851 secondary studies which cited a retracted paper. Papers retracted for fraud (n=70) treated more patients per study (p<0.01) than papers retracted for error (n=110). Conclusions Many patients are put at risk by retracted studies. These are conservative estimates, as only patients enrolled in published clinical studies were tallied. (shrink)

Published posthumously in 1964, this volume contains a fantastic collection of essays by R. G. Collingwood on the subject of art and it's relationship with philosophy. Robin George Collingwood, FBA (1889 - 1943) was an English historian, philosopher, and archaeologist most famous for his philosophical works including "The Principles of Art" (1938) and the posthumously-published "The Idea of History" (1946). This fascinating volume will appeal to those with an interest in Collingwood's seminal work, and is not to be missed by (...) students of philosophy and art. Contents include: "Ruskin not a Philosophical Writer," "Ruskin's Attitude towards Philosophy," "On the Philosophy of Non-Philosophers," "Logicism and Historicism," "Ruskin as Historicist," "The Anti-Historicism of Ruskin's Contemporaries," "The Unity of the Spirit: Corollaries and Illustrations," "Ruskin and Browning," etc. Many vintage books such as this are increasingly scarce and expensive. It is with this in mind that we are republishing this volume today in an affordable, modern edition complete with a specially-commissioned new biography of the author. (shrink)

For a theist, a man's duty is to conform to the announced will of God. Yet a theist who makes this claim about duty is faced with a traditional dilemma first stated in Plato's Euthyphro—are actions which are obligatory, obligatory because God makes them so, or does God urge us to do them because they are obligatory anyway? To take the first horn of this dilemma is to claim that God can of his free choice make any action obligatory or (...) non-obligatory. The critic claims that the theist cannot take this horn, for God cannot make bad actions good. (shrink)

Anyone interested in the morality of suicide reads David Hume's essay on the subject even today. There are numerous reasons for this, but the central one is that it sets up the starting point for contemporary debate about the morality of suicide, namely, the debate about whether some condition of life could present one with a morally acceptable reason for autonomously deciding to end one's life. We shall only be able to have this debate if we think that at least (...) some acts of suicide can be moral, and we shall only be able to think this if we give up the blanket condemnation of suicide that theology has put in place. I look at this strategy of argument in the context of the wider eighteenth-century attempt to develop a non-theologically based ethic. The result in Hume's case is a very modern tract on suicide, with voluntariness and autonomy to the fore and with reflection on the condition of one's life and one's desire to carry on living a life in that condition the motivating circumstance.

What is science? How is scientific knowledge affected by the society that produces it? Does scientific knowledge directly correspond to reality? Can we draw a line between science and pseudo-science? Will it ever be possible for computers to undertake scientific investigation independently? Is there such a thing as feminist science? In this book the author addresses questions such as these using a technique of 'cognitive play', which creates and explores new links between the ideas and results of contemporary history, philosophy, (...) and sociology of science. New ideas and approaches are applied to a wide range of case studies, many of them from controversial and contested science. This book will be of interest to historians and sociologists of science, to anyone interested in science studies, and to educated general readers with an interest in the history, philosophy, and social context of science.

Informed choice is increasingly recognised as important in supporting patient autonomy and ensuring that people are neither deceived nor coerced. In cancer screening the emphasis has shifted away from just promoting the benefits of screening to providing comprehensive information to enable people to make an informed choice. Cancer screening programmes in the UK now have policies in place which state that it is their responsibility to ensure that individuals are making an individual informed choice. There is a need to evaluate (...) whether such policies mean that those people invited for screening are making informed choices, and how comprehensive information affects other variables such as uptake, cost effectiveness, and satisfaction. At the present time, there is no validated measure of informed choice in cancer screening. Such a measure could be used to evaluate the effectiveness of interventions to increase informed choice and levels of informed choice in a population invited for screening. It could encourage health professionals to be accountable. Factors important when measuring informed choice in cancer screening include an individual’s understanding of the limitations of screening, the ability to make an autonomous choice, and the difference between choice and behaviour.

CONTRARY TO GOODMAN’S VIEW, A CLEAR DISTINCTION CAN BE MADE BETWEEN QUALITATIVE AND POSITIONAL PREDICATES. HENCE WE CAN EXPLAIN THAT WE OUGHT TO PROJECT ’GREEN’ RATHER THAN ’GRUE’ BECAUSE THE LATTER IS A POSITIONAL PREDICATE, RATHER THAN BECAUSE THE LATTER IS LESS WELL ENTRENCHED. A PREDICATE IS POSITIONAL IF, TO FIND OUT AS CERTAINLY AS WE CAN WHETHER IT APPLIES TO AN OBJECT, WE HAVE TO FIND OUT THE LATTER’S SPATIO-TEMPORAL LOCATION.
