According to the local risk-neutrality theorem an agent who has the opportunity to invest in an uncertain asset does not buy it or sell it short iff its expected value is equal to its price, independently of the agent's attitude towards risk. Contrary to that it is shown that, in the context of expected utility theory with differentiable vNM utility function, but without the assumption of stochastic constant returns to scale, nondegenerate intervals of no-trade prices may exist. With (...) a quasiconcave expected utility function they do if, and only if, the agent is risk averse of order one. (shrink)

_ Source: _Volume 95, Issue 3, pp 368 - 413 Frege famously maintained that concepts are not objects. A key argument of Frege’s for this view is, in outline, as follows: if we are to account for the unity of thought, concepts must be deemed _unsaturated_; since objects are, by contrast, saturated entities, concepts cannot be objects. The author investigates what can be made of this argument and, in particular, of the unsaturated/saturated distinction it invokes. Systematically exploring a range of (...) reconstructions suggested by Frege’s writings, and drawing on contemporary work, the author illustrates that no plausible reconstruction is forthcoming. In essence, it is altogether unclear how to simultaneously substantiate, on the one hand, the claim that unsaturated entities must be recognized in order to account for unity and, on the other, the claim that unsaturatedness is incompatible with objecthood.

Are there ethics justifying anti-colonial violence? How and why did the violence and visions of nationalist movements become incorporated by colonial and neo-colonial rule? Using the insurrection by the Malayan Communist Party (1948–1960) as an example, this book argues that resorting to violence sped up the decolonisation of British Malaya by forcing its colonial administration to invent Malay nationalism and pursue ameliorative social policy among the Chinese diaspora community in a manner clearly derived from the Party’s platform. Yet this was (...) not the same as giving the country economic emancipation from the expectations of neo-colonial rule. Violence and Emancipation in Colonial Ideology entertains no warm colonial memories of the cold war years. Confirming Price’s reputation as a plain speaking critic of Empire apologia, this book asks how colonial ideology was considered to be beneath Europe yet desperately needed by it. He faces down nostalgic communities defending an outdated view that “might was right” in South East Asia and that communism failed to contribute to the world that came to be. Using an Althusserian assumption, the book begs the question: if a late colonial state was subjective, then how did it claim a sufficiently objective mantle to rule and how did ideological techniques enable this?

William James said that sometimes detailed philosophical argument is irrelevant. Once a current of thought is really under way, trying to oppose it with argument is like planting a stick in a river to try to alter its course: “round your obstacle flows the water and ‘gets there just the same’”. He thought pragmatism was such a river. There is a contemporary river that sometimes calls itself pragmatism, although other titles are probably better. At any rate it is the denial (...) of differences, the celebration of the seamless web of language, the soothing away of distinctions, whether of primary versus secondary, fact versus value, description versus expression, or of any other significant kind. What is left is a smooth, undifferentiated view of language, sometimes a nuanced kind of anthropomorphism or “internal” realism, sometimes the view that no view is possible: minimalism, deflationism, quietism. Wittgenstein is often admired as a high priest of the movement. Planting a stick in this water is probably futile, but having done it before I shall do it again, and—who knows?—enough sticks may make a dam, and the waters of error may subside.

Citizens' juries are commended as a new technique for democratising health service reviews. Their usefulness is said to derive from a reliance on citizens' rational deliberation rather than on the immediate preferences of the consumer. The author questions the assertion of critical detachment and asks whether juries do in fact employ reason as a means of resolving fundamental disagreements about service provision. He shows that juries promote not so much a critically detached point of view as a particular evaluative framework (...) suited to the bureaucratic idiom of social welfare maximisation. Reports of jury practice reveal a tendency among juries to suppress by non-rational means the everyday moral language of health care evaluation and substitute for it a system of thought in which it can be deemed permissible to deny treatment to sick people. The author concludes that juries are chiefly concerned with non-rational persuasion and because of this they are morally and democratically irrelevant. Juries are no substitute for voting when it comes to protecting the public from zealous minorities. (shrink)

The subject of my lecture is an appropriate one for several reasons. The first is purely chronological. Hume's first and greatest work, the Treatise of Human Nature, was published in 1739, two hundred years ago. Its illustrious author was then quite unknown in the world, and as he tells us himself the book “fell dead-born from the press.” But by the end of the eighteenth century its reputation was securely established, and it has long been regarded as one of the (...) masterpieces of European thought, and as the classical statement of the Empiricist Philosophy. It is true that, like other classics, it has had its ups and downs. During the Absolute Idealist period, which ended early in the present century, Hume was the great bogey-man, and the duty of all self-respecting philosophers was to refute him. In our own day things are different. Empiricism, despite many obituary notices, is very much alive again. And this time it is in close alliance with Natural Science, and has equipped itself with all the technique of modern Symbolic Logic; it is more vigorous in construction and more formidable in criticism than it has ever been before. Consequently Hume is no longer the bogey-man. People now read the Treatise not as an awful warning, but as a source of stimulus and illumination. Incidentally, we can now enjoy his admirable style without any qualms. It is no longer thought that if a philosopher writes in clear and entertaining English, what he writes must therefore be either superficial or false. We regard obscurity and turgidity as demerits, not as signs of profound thinking. Moreover, we have learned to appreciate the eighteenth century, of which Hume was one of the most characteristic products. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy of Music Education Review 12.1 (2004) 30-42 [Access article in PDF] How Can Music Seem to be Emotional? Kingsley Price Johns Hopkins University Preliminary Let me make some preliminary remarks about my question. First, the distinction employed in it, the distinction between seeming and reality, comes in two forms. The first is inclusive. A thing that really is so-and-so also seems to be so-and-so. The butler really is (...) guilty and seems guilty as well. The second is exclusive. A thing that is really not so-and-so seems to be so-and-so. The butler is really not guilty but seems to be guilty. The distinction that underlies my question is of the exclusive form.Second, the music I ask about is not music as read from scores on paper or held in memory. Nor is it music that contains linguistic elements-words or gestures as in song, opera, ballet, etc. Rather, it is purely instrumental music, and that as perceived or heard.Third, the emotions I refer to are not physiological conditions that may cause them, nor the behavior that may express them, but the conscious feelings we find in ourselves when we are undergoing emotion. [End Page 30] The Problem Persons (perhaps even the lower animals) can seem to be, without really being, emotional. They are pretending, or we perceive mistakenly. There is no difficulty, in principle, in explaining the situation. But there would be if they were sculptured persons only-that is, if they could not possibly be emotional. A sculpture cannot seem to be emotional by pretending it; nor can we perceive mistakenly that it is emotional when we know that it is a sculpture only.Much music is like sculpture. Not personal, we know that it cannot really be emotional. None-the-less, we hear the wedding march from Mendelssohn's music for A Midsummer Night's Dream as joyful, the second movement of Chopin's Sonata in B-flat Minor as sorrowful, "The Great Fugue" as grimly resigned, the first movement of the first Razumowski as hopeful, etc. How can this be so? How can music seem to be emotional?I look for an answer to this question, first, within the perception, the hearing of music, and then, without it in its meaning. If seeming emotionality is found in either place, I shall have answered the question. And now, for the first place. The Perception In sense perception there are two major constituents.1 One is awareness; the other is the object of awareness. Awareness occurs in all the kinds of consciousness-in remembering, imagining, dreaming, and thinking, for example, as well as in sense perception. In this last, it is brought about by operation of the senses; while in the others, that operation plays no direct part. But although it differs in its cause, awareness in sense perception is precisely the same, considered in itself, as it is in all the other kinds of consciousness, considered in themselves.What is awareness? It cannot be explained, as many notions can, by eliciting its parts. To understand what squareness is, for example, we need only bring forward the parts that constitute it: four straight lines equal in length, four right angles, and closed plane figure. But awareness has no parts and cannot be explained in this way. To call attention to its simplicity and its identity in all kinds of consciousness, indeed, is all that can be done to explain it though we might add the simile that likens awareness to the light that brings things before our minds out of the dark that conceals them in its absence.Now, hearing is a kind of sense perception-the kind that occurs by virtue of operation of the auditory organs; and music heard is one of the objects of auditory awareness. Can we understand how this object can seem to be emotional by appeal to the awareness of it? If that awareness seemed to exist and did not really do so, the answer would be that we cannot since the awareness of it... (shrink)

Reports of phantom limbs amongst aplasics have often been presented as evidence that body image is ‘hard-wired’ in the brain and that neither sensory input nor proprioceptive feedback are essential to its formation. Although attempts have been made to account for these phantoms by other means, these have been on a case by case basis and no satisfactory alternative framework has been proposed. This paper collates the accounts of aplasic phantoms and presents them as compatible with a four-part hypothesis, in (...) which body image is learnt from experience during both pre- and post-natal development, and in which cross-cortical connections and mirror neurons play prominent roles. This model unites several previously disparate theories to offer a viable solution to several longstanding phantom limb mysteries and serves to highlight avenues worthy of further inquiry. (shrink)

In a recent paper, Richard Rorty begins by telling us why pragmatists such as himself are inclined to identify truth with justification: ‘Pragmatists think that if something makes no difference to practice, it should make no difference to philosophy. This conviction makes them suspicious of the distinction between justification and truth, for that distinction makes no difference to my decisions about what to do.’ (1995, p. 19) Rorty goes on to discuss the claim, defended by Crispin Wright, that truth is (...) a normative constraint on assertion. He argues that this claim runs foul of this principle of no difference without a practical difference: ‘The need to justify our beliefs to ourselves and our fellow agents subjects us to norms, and obedience to these norms produces a behavioural pattern that we must detect in others before confidently attributing beliefs to them. But there seems to be no occasion to look for obedience to an additional norm – the commandment to seek the truth. For – to return to the pragmatist doubt with which I began – obedience to that commandment will produce no behaviour not produced by the need to offer justification.’ (1995, p. 26) Again, then, Rorty appeals to the claim that a commitment to a norm of truth rather than a norm of justification makes no behavioural difference. This is an empirical claim, testable in principle by comparing the behaviour of a community of realists (in Rorty’s sense) to that of a community of pragmatists. In my view, the experiment would show that the claim is unjustified, indeed false. I think that there is an important and widespread behavioural pattern that depends on the fact that speakers do take themselves to be subject to such an additional norm. Moreover, it is a.. (shrink)

Can an agent deliberating about an action A hold a meaningful credence that she will do A? 'No', say some authors, for 'Deliberation Crowds Out Prediction' (DCOP). Others disagree, but we argue here that such disagreements are often terminological. We explain why DCOP holds in a Ramseyian operationalist model of credence, but show that it is trivial to extend this model so that DCOP fails. We then discuss a model due to Joyce, and show that Joyce's rejection of DCOP rests (...) on terminological choices about terms such as 'intention', 'prediction', and 'belief'. Once these choices are in view, they reveal underlying agreement between Joyce and the DCOP-favouring tradition that descends from Ramsey. Joyce's Evidential Autonomy Thesis (EAT) is effectively DCOP, in different terminological clothing. Both principles rest on the so-called 'transparency' of first-person present-tensed reflection on one's own mental states. (shrink)

Is non-cognitivism compatible with minimalism about truth? A contemporary argument claims not, and therefore that moral realists, for example, should take heart from the popularity of semantic minimalism. The same is said to apply to cognitivism about other topics—conditionals, for example—for the argument depends only on the fact that ordinary usage applies the notions of truth and falsity to utterances of the kind in question. Given this much, minimalism about truth is said to leave no room for the view that (...) the utterances concerned are non-cognitive in nature. (shrink)

There is a long-standing disagreement in the philosophy of probability and Bayesian decision theory about whether an agent can hold a meaningful credence about an upcoming action, while she deliberates about what to do. Can she believe that it is, say, 70% probable that she will do A, while she chooses whether to do A? No, say some philosophers, for Deliberation Crowds Out Prediction (DCOP), but others disagree. In this paper, we propose a valid core for DCOP, and identify terminological (...) causes for some of the apparent disputes. (shrink)

It has often been suggested that retrocausality offers a solution to some of the puzzles of quantum mechanics: e.g., that it allows a Lorentz-invariant explanation of Bell correlations, and other manifestations of quantum nonlocality, without action-at-a-distance. Some writers have argued that time-symmetry counts in favour of such a view, in the sense that retrocausality would be a natural consequence of a truly time-symmetric theory of the quantum world. Critics object that there is complete time-symmetry in classical physics, and yet no (...) apparent retrocausality. Why should the quantum world be any different? This note throws some new light on these matters. I call attention to a respect in which quantum mechanics is different, under some assumptions about quantum ontology. Under these assumptions, the combination of time-symmetry without retrocausality is unavailable in quantum mechanics, for reasons intimately connected with the differences between classical and quantum physics (especially the role of discreteness in the latter). Not all interpretations of quantum mechanics share these assumptions, however, and in those that do not, time-symmetry does not entail retrocausality. (shrink)

Understanding the nature of pain depends, at least partly, on recognizing its subjectivity (thus, its first-person epistemology). This in turn requires using a first-person experiential method in addition to third-person experimental approaches to study it. This paper is an attempt to spell out what the former approach is and how it can be integrated with the latter. We start our discussion by examining some foundational issues raised by the use of introspection. We argue that such a first-person method in the (...) scientific study of pain (as in the study of any experience) is in fact indispensable by demonstrating that it has in fact been consistently used in conjunction with conventional third-person methodologies, and this for good reasons. We show that, contrary to what appears to be a widespread opinion, there is absolutely no reason to think that the use of such a first-person approach is scientifically and methodologically suspect. We distinguish between two uses of introspective methods in scientific experiments: one draws on the subjects’ introspective reports where any investigator has equal and objective access. The other is where the investigator becomes a subject of his own study and draws on the introspection of his own experiences. We give examples using and/or approximating both strategies that include studies of second pain summation and its relationship to neural activities, and brain imaging- psychophysical studies wherein sensory and affective qualities of pain are correlated with cerebral cortical activity. We explain what we call the experiential or phenomenological approach that has its origins in the work of Price and Barrell (1980). This approach capitalizes on the scientific prospects and benefits of using the introspection of the investigator. We distinguish between its vertical and horizontal applications. Finally, we conclude that integrating such an approach to standard third-person methodologies can only help us in having a fuller understanding of pain and of conscious experience in general.

Speech act theory is one of the more lasting products of the linguistic movement in philosophy of the mid−Twentieth century. Within philosophy itself the movement's products did not in general prove so durable. Particularly striking in this respect is the perceived fate of what was one of the most characteristic applications of the linguistic turn in philosophy, namely the view that many traditional philosophical problems are such as to yield to an understanding of the distinctive function of a particular part (...) of language. Most typically, the crucial insight was held to be that despite appearances, the function of the part of language in question is not assertoric, or descriptive, and that the traditional problems arose at least in part from a failure to appreciate this point. Thus problems in moral philosophy were thought to yield to an appreciation that moral discourse is expressive rather than descriptive, problems in the philosophy of mind to an understanding of distinctive r×le of psychological ascriptions, and so on. The philosophical journals of the 1950s are rich with views like these. (No general term for this approach seems to have become widely accepted at the time. I shall call it "non−factualism", for what it denies, most characteristically, is the fact−stating r×le of language of a certain kind.). (shrink)

The best case for thinking that quantum mechanics is nonlocal rests on Bell's Theorem, and later results of the same kind. However, the correlations characteristic of Einstein–Podolsky–Rosen (EPR)–Bell (EPRB) experiments also arise in familiar cases elsewhere in quantum mechanics (QM), where the two measurements involved are timelike rather than spacelike separated; and in which the correlations are usually assumed to have a local causal explanation, requiring no action-at-a-distance (AAD). It is interesting to ask how this is possible, in the light (...) of Bell's Theorem. We investigate this question, and present two options. Either (i) the new cases are nonlocal too, in which case AAD is more widespread in QM than has previously been appreciated (and does not depend on entanglement, as usually construed); or (ii) the means of avoiding AAD in the new cases extends in a natural way to EPRB, removing AAD in these cases too. There is a third option, viz., that the new cases are strongly disanalogous to EPRB. But this option requires an argument, so far missing, that the physical world breaks the symmetries which otherwise support the analogy. In the absence of such an argument, the orthodox combination of views—action-at-a-distance in EPRB, but local causality in its timelike analogue—is less well established than it is usually assumed to be. 1 Introduction1.1 Background1.2 Outline of the argument2 The Experiments2.1 Standard EPRB2.2 Sideways EPRB2.3 Comparing the experiments2.4 The need for beables3 The Symmetry Considerations3.1 The action symmetry3.2 Time-symmetry in SEPRB4 The Basic Trilemma4.1 An intuitive defence of Option III?5 Avoiding the Trilemma?6 The Classical Objection7 Defending Option III7.1 The free will argument7.2 Independence and consistency8 Entanglement and Epistemic Perspective.

The first half of Mr. Burgener's article is a very clear and very just exposition of my views. There is, however, one point which he may not have appreciated fully, and that is the "climate of opinion" in which I was writing, and against which I was reacting. One of my main aims was to protest against the transformation of the empiricist epistemology into a linguistic epistemology, a transformation initiated by the Logical Positivists of the 1930's, and completed by Wittgenstein (...) and his disciples. Hence the amount of space devoted to sign-cognition, to the intelligence of animals, and to image-thinking, all of which are non-verbal or pre-verbal. But, as he has surmised, I am really just an old-fashioned British empiricist. I am fighting on two fronts, as it were, throughout the book: against a purely linguistic conception of thinking on one side, and against the "classical" inspective conception of it on the other. And in this two-fold battle, I am taking just the line which Locke, Berkeley, and Hume would have taken if they had been alive today: one which they do in fact suggest in their writings, though of course they could not anticipate the lengths to which the purely linguistic or verbalistic conception of thinking would go, or how it would ally itself with a behavioristic conception of human personality. One of the things I most object to in current British philosophy is the attack which is made on all sides of the "inner life," the attempt to show that there is no such thing, or that it is a mere muddle to suppose there is, or that to the extent that it does exist it is of no importance. Perhaps there is some connection between this attack on the inner life and the attack on private life which is made by the politicians, social reformers, and economic planners. Perhaps they are only two aspects of the same thing. Anyway, between them they have gone a long way towards a kind of "dehumanisation" of man; and this seems to me one of the darkest features of the very dark age in which we live. I feel concerned about it not only as an epistemologist, but also as a religious person, or at least as a person who is interested in religion in a very undenominational way. Religion, as I view it, is very closely connected with the "inner life"; and if one is forbidden to take an interest in the "inner life," religion will wither away from sheer inanition. At any rate, the most mystical types of religion will, and these are the ones which seem to me the most important. (shrink)

Can physics explain the difference between past and future? The laws of physics seem to be time-symmetric. If they allow a process with one temporal orientation, they allow it in reverse. Yet many ordinary pro– cesses seem to be irreversible. Ilya Prigogine calls this the time paradox, and argues that the solution lies in chaos theory, and related methods pioneered by himself and his Brussells colleagues—a radical alternative, he thinks, to a tradition dating from Boltzmann.

Physics takes for granted that interacting physical systems with no common history are independent, before their interaction. This principle is time-asymmetric, for no such restriction applies to systems with no common future, after an interaction. The time-asymmetry is normally attributed to boundary conditions. I argue that there are two distinct independence principles of this kind at work in contemporary physics, one of which cannot be attributed to boundary conditions, and therefore conflicts with the assumed T (or CPT) symmetry of microphysics. (...) I note that this may have interesting ramifications in quantum mechanics. (shrink)

Does not the theory of a general tendency of entropy to diminish [sic] take too much for granted? To a certain extent it is supported by experimental evidence. We must accept such evidence as far as it goes and no further. We have no right to supplement it by a large draft of the scientific imagination.

I am very grateful to Professor R. W. Sleeper for his critical comments on my article, as also for the kind way in which he has expressed them. I should now like to make a few comments on his comments. May I first say that I have no objection to being metaphysical? I do not like the word ‘metaphysics’ very much, and wish that we could find a less provocative one. But still, I do think that the difference between the (...) reducible and the irreducible belief-in is a difference which there really is . Moreover, I fully admit that when we believe in God we are making a factual claim. It is, of course, a factual claim of rather a special kind. If it is a fact that there is a supreme Being, ‘The Lord of All’, this is not just one fact among others. It is not quite like the fact that there is a stormy north-westerly wind this morning. One could not just give a list of facts and add at the end, ‘There is also another fact which I had forgotten to mention: there is a God’. All the same, this factual claim, like others, does need to be justified; and how is it to be justified? I am afraid that the brief hint which I offered elsewhere on this subject is indeed ‘not good enough’ as it stands . To be even half good enough, it needs much more elaboration, and I agree that there is much force in Mr Gunderson's criticisms. (shrink)

Carnap was one of the first to use the term 'non-cognitivism'. His linguistic pluralism and voluntarism, and his deflationary views of ontology and semantics, are highly congenial to those of us who want to take non-cognitivism in the direction of global expressivism. In his own case, however, this move is in tension with his continued endorsement of what he calls 'the general thesis of logical empiricism', that 'there is no third kind of knowledge besides empirical and logical knowledge.’ So while (...) Carnap clears a path towards global expressivism, he doesn't seem to appreciate what it requires him to leave behind. (shrink)

Context The attitudes of medical professionals towards physician assisted dying have been widely discussed. Less explored is the level of agreement among physicians on the possibility of ‘rational suicide’—a considered suicide act made by a sound mind and a precondition of assisted dying legislation. Objective To assess attitudes towards rational suicide in a representative sample of senior doctors in England and Wales. Methods A postal survey was conducted of 1000 consultants and general practitioners randomly selected from a commercially available database. (...) The main outcome of interest was level of agreement with a statement about rational suicide. Results The corrected participation rate was 50%; 363 questionnaires were analysed. Overall 72% of doctors agreed with the possibility of rational suicide, 17% disagreed, and 11% were neutral. Doctors who identified themselves as being more religious were more likely to disagree. Some doctors who disagreed with legalisation of physician assisted suicide nevertheless agreed with the concept of rational suicide. Conclusions Most senior doctors in England and Wales feel that rational suicide is possible. There was no association with specialty. Strong religious belief was associated with disagreement, although levels of agreement were still high in people reporting the strongest religious belief. Most doctors who were opposed to physician assisted suicide believed that rational suicide was possible, suggesting that some medical opposition is best explained by other factors such as concerns of assessment and protection of vulnerable patients.

Hume maintained that, philosophically speaking, there is no difference between exiting a room out of the first-floor window and using the door. Nevertheless, Hume’s reason and common sense prevailed over his scepticism and he advocated that we should always use the door. However, we are currently living in a world that is more seriously committed to the Humean philosophy of empiricism than he was himself and thus the potential to act inappropriately is an ever-present potential. In this paper, I explore (...) how Hume’s two versions of causality have detrimentally affected our ability both to arrive at and to use research to improve human well-being. I illustrate my argument with an example of what I think is an incorrect yet supposedly scientifically sound assumption: that absenteeism causes poor school attainment. Instead I make the interdisciplinary argument that absenteeism is better understood as an aggravating symptom of a number of other causes of poor attainment, such as poverty and individual psychological factors. I suggest that an instrumental, punitive policy against parents whose children tend to be absent from school may be ineffectual or even counterproductive if the objective is to improve the well-being of those children. To support my argument, I introduce the critical realist idea of transfactuality. Using the example of research into moon rocks, I show how mainstream science uses transfactuality despite its empiricist aversion to it. I also suggest that it is our honesty, integrity, and stoicism that lead us to the extreme overthrow of reason and common sense that we see today in many of the UK’s social policies; an overthrow that Hume himself did not achieve. Metaphorically speaking, British professionals, stoically and honestly believing in the ability of their trusted research correlations to guide their action, are exiting out of the first-floor window rather than using the door. This is a significant barrier to our ability to devise and implement social policy. (shrink)

With a global commitment to scaling up AIDS care and treatment in resource-poor settings for some of the most HIV-affected countries in Africa, availability of antiretroviral treatment is no longer the principal obstacle to expanding access to treatment. A shortage of trained healthcare personnel to initiate treatment and manage patients represents a more challenging barrier to offering life-saving treatment to all patients in need. Physician-centered treatment policies accentuate this challenge. Despite evidence that task shifting for nurse-centered AIDS patient care is (...) effective and can alleviate severe physician shortages that currently obstruct treatment scale-up, political commitment and policy action to support task shifting models of care has been slow to absent. In this paper we review the evidence in support of task shifting for AIDS treatment in Africa and argue that continued policy inaction amounts to unwarranted healthcare rationing and as such is ethically untenable.

In 'General Propositions and Causality' Ramsey rejects his earlier view that universal generalizations are infinite conjunctions, arguing that they are not genuine propositions at all. We argue that his new position is unstable. The issues about infinity that lead Ramsey to the new view are essentially those underlying Wittgenstein's rule-following considerations. If they show that generalizations are not genuine propositions, they show that there are no genuine propositions. The connection raises interesting historical questions about the direction of influence between Ramsey (...) and Wittgenstein, the origin of the rule-following argument, and the influence of writers such as Brouwer.

Philosophers have often raised the question what kind of information is available to vision. For instance, Berkeley argued that one could not see depth, Hume argued that one could not see necessary connections and, according to Paul Guyer, Kant held that there is no perception of change, but only change of perception (Guyer 2004).

BackgroundAssisted dying has wide support among the general population but there is evidence that those providing care for the dying may be less supportive. Senior doctors would be involved in implementing the proposed change in the law. We aimed to measure support for legalising physician assisted dying in a representative sample of senior doctors in England and Wales, and to assess any association between doctors' characteristics and level of support for a change in the law.MethodsWe conducted a postal survey of (...) 1000 consultants and general practitioners randomly selected from a commercially available database. The main outcome of interest was level of agreement with any change in the law to allow physician assisted suicide.ResultsThe corrected participation rate was 50%. We analysed 372 questionnaires. Respondents' views were divided: 39% were in favour of a change to the law to allow assisted suicide, 49% opposed a change and 12% neither agreed nor disagreed. Doctors who reported caring for the dying were less likely to support a change in the law. Religious belief was also associated with opposition. Gender, specialty and years in post had no significant effect.ConclusionMore senior doctors in England and Wales oppose any step towards the legalisation of assisted dying than support this. Doctors who care for the dying were more opposed. This has implications for the ease of implementation of recently proposed legislation. (shrink)

Bertrand Russell’s celebrated essay “On the Notion of Cause” was first delivered to the Aristotelian Society on 4 November 1912, as Russell’s Presidential Address. The piece is best known for a passage in which its author deftly positions himself between the traditional metaphysics of causation and the British crown, firing broadsides in both directions: “The law of causality”, Russell declares, “Like much that passes muster in philosophy, is a relic of a bygone age, surviving, like the monarchy, only because it (...) is erroneously supposed to do no harm.” To mark the lecture’s centenary, I offer a contemporary view of the issues Russell here puts on the table, and of the health or otherwise, at the end of the essay’s first century, of his notorious conclusion.

It has been suggested that some of the puzzles of QM are resolved if we allow that there is retrocausality in the quantum world. In particular, it has been claimed that this approach offers a path to a Lorentz-invariant explanation of Bell correlations, and other manifestations of quantum "nonlocality", without action-at-a-distance. Some writers have suggested that this proposal can be supported by an appeal to time-symmetry, claiming that if QM were made "more time-symmetric", retrocausality would be a natural consequence. Critics (...) object that there is complete time-symmetry in classical physics, and yet no apparent retrocausality. Why should QM be any different? In this note I call attention to a respect in which QM is different, under some assumptions about quantum ontology. Under these assumptions, the option of time-symmetry without retrocausality is not available in QM, for reasons intimately connected with the fundamental differences between classical and quantum physics (especially the role of discreteness in the latter).

Coetzee, Charles Taylor, Alasdair MacIntyre, Elaine Pagels, and Karen King—and with extended reference to Jonathan Lear's study of “cultural devastation,” Radical Hope—Jeffrey Perl explores the possibility that the fear of anomie is misplaced. He argues that, in comparison with the violence and narrowness of any given social order, anomie may well be preferable, and, (...) in any case, may be no more than another name for quietism.

Research on the effects of background music has a long history. Early work was not embedded within a theoretical framework, was often poorly conceptualised and produced equivocal findings. This paper reports two studies exploring the effects of music, perceived to be calming and relaxing, on performance in arithmetic and on a memory task in children aged 10-12. The calming music led to better performance on both tasks when compared with a no-music condition. Music perceived as arousing, aggressive and unpleasant disrupted (...) performance on the memory task and led to a lower level of reported altruistic behaviour by the children. This suggests that the effects of music on task performance are mediated by arousal and mood rather than affecting cognition directly. The findings are discussed in relation to possible practical applications in the primary school and the home. (shrink)
