This paper examines two puzzles of indeterminacy. The first puzzle concerns the hypothesis that there is a unified phenomenon of indeterminacy. How are we to reconcile this with the apparent diversity of reactions that indeterminacy prompts? The second puzzle focuses narrowly on borderline cases of vague predicates. How are we to account for the lack of theoretical consensus about what the proper reaction to borderline cases is? I suggest (building on work by Maudlin) that the characteristic feature of indeterminacy is (...) alethic normative silence, and use this to explain both plurality and lack of consensus. (shrink)

In the literature on supervaluationism, a central source of concern has been the acceptability, or otherwise, of its alleged logical revisionism. I attack the presupposition of this debate: arguing that when properly construed, there is no sense in which supervaluational consequence is revisionary. I provide new considerations supporting the claim that the supervaluational consequence should be characterized in a ‘global’ way. But pace Williamson (1994) and Keefe (2000), I argue that supervaluationism does not give rise to counterexamples to familiar inference-patterns (...) such as reductio and conditional proof.

From the 5th edition of Beauchamp and Childress' Principles of Biomedical Ethics, the problem of common morality has been given a more prominent role and emphasis. With the publication of the 6th and latest edition, the authors not only attempt to ground their theory in common morality, but there is also an increased tendency to identify the former with the latter. While this stratagem may give the impression of a more robust, and hence stable, foundation for their theoretical construct, we (...) fear that it comes with a cost, namely the need to keep any theory in medical ethics open to, and thereby aware of, the challenges arising from biomedical research and clinical practice, as well as healthcare systems. By too readily identifying the moral life of common morality with rule-following behaviour, Beauchamp and Childress may even be wrong about the nature of common morality as such, thereby founding their, by now, classic theory on quicksand instead of solid rock.

An obligation may take either of two forms, each form being reported in a different way. For example, when we report the obligation of parents to care for their children, if it is the moral obligation we mean, we will say ‘Parents ought to look after their children’ but if we mean the legal obligation, we will say ‘Parents have to look after their children’. The law specifies that people shall do thus and so, not that they ought to do (...) thus and so. (shrink)

Forty‐nine subjects judged the relevancy of sentence parts of a word problem (the Allsports problem). Patterns of subjects' judgments suggest three problem‐solving heuristics: a SETS heuristic, a TIME heuristic, and a QUESTION heuristic. Presentation of the question before the problem tends to suppress SETS and TIME heuristics. A computer program (ATTEND) is presented to simulate subjects' behavior on the Allsports problem. The program is context‐sensitive in that it can change a relevance judgment upon the acquisition of further information. Averaged subject (...) judgments and ATTEND judgments agree for 87% of the items. (shrink)

*This work is no longer under development* Two major themes in the literature on indicative conditionals are that the content of indicative conditionals typically depends on what is known;1 that conditionals are intimately related to conditional probabilities.2 In possible world semantics for counterfactual conditionals, a standard assumption is that conditionals whose antecedents are metaphysically impossible are vacuously true.3 This aspect has recently been brought to the fore, and defended by Tim Williamson, who uses it in to characterize alethic necessity by (...) exploiting such equivalences as: A⇔¬A A. One might wish to postulate an analogous connection for indicative conditionals, with indicatives whose antecedents are epistemically impossible being vacuously true: and indeed, the modal account of indicative conditionals of Brian Weatherson has exactly this feature.4 This allows one to characterize an epistemic modal by the equivalence A⇔¬A→A. For simplicity, in what follows we write A as KA and think of it as expressing that subject S knows that A.5 The connection to probability has received much attention. Stalnaker suggested, as a way of articulating the ‘Ramsey Test’, the following very general schema for indicative conditionals relative to some probability function P: P = P 1For example, Nolan ; Weatherson ; Gillies. 2For example Stalnaker ; McGee ; Adams. 3Lewis. See Nolan for criticism. 4‘epistemically possible’ here means incompatible with what is known. 5This idea was suggested to me in conversation by John Hawthorne. I do not know of it being explored in print. The plausibility of this characterization will depend on the exact sense of ‘epistemically possible’ in play—if it is compatibility with what a single subject knows, then can be read ‘the relevant subject knows that p’. If it is more delicately formulated, we might be able to read as the epistemic modal ‘must’. (shrink)

It is meet and right that pride and humility should be the two human characteristics on which University sermons have to be preached. Left to myself, although I might have picked on my modesty as something I should share with you, I should have given the preeminence to other among my sins than pride. My greed, my sloth, my avarice or, in this salacious age my lust, are subjects on which I could tell you much that might interest you. Pride (...) lacks immediate appeal. We are not sure what it is, or whether it is a bad thing, when we think of it in purely individual terms. But when we consider it collectively, we can see that it is, together with humility, something Oxford is peculiarly well qualified to preach on. We all of us are proud of our university. We were proud, and our schoolmasters were proud, when we first got our places here. We are, dons and undergraduates alike, proud of our colleges, each grateful that good fortune has brought him to the best college in Oxford, and anxious that everyone else should secretly acknowledge it to be the best. Our parents were proud when we took our degrees, and although we profess to be unconcerned with classes, we are deeply content to record our firsts when occasion requires us to do so, or have our contemporaries allude to them as opportunity offers. We are studious, as dons, not to pull rank, safe in the knowledge that others will do it for us, and that we shall receive the deference due to a fellow of an Oxford college. In an age that is egalitarian in theory but elitist at heart, Oxford men have benefited greatly, as other forms of social eminence have been eroded, leaving a clear field for our own claims to public esteem, which are, if not entirely unchallenged, still generally allowed. Oxford is, as we like to be told by outsiders, a centre of excellence, and a lot of the resplendence rubs off on us, not altogether undeservedly. It is, as we corporately admit on Commemoration Sunday, largely due to our having entered into other men's labours.. (shrink)

Equality is one of the great issues of our age, but few people stop to wonder at its being an issue in politics at all. Yet it is surprising that a concept which has its natural habitat in the mathematical sciences should have taken root in our thinking about how we should be governed. We do not naturally think of society in terms of group theory, or rings or fields, and have long been aware of the difficulties in establishing any (...) over-arching social or political order. But we unthinkingly assume that we can meaningfully ask, and reliably tell, whether people are, or ought to be, equal to one another even while admitting how difficult it would be to say whether they were more or less than one another. Formal logic can help. Equality is an equivalence relation, that is to say one that is transitive, symmetric and reflexive. Equivalence classes pick out classes of people or things that are the same, or similar , in some respect or other. There are many such, and we need to specify in respect of what two things are or are not equivalent before we are saying, or asking, anything definite. I can be equivalent to you in respect of age, or height, or weight, and many equivalence classes— contemporaries, co-religionists, comrades—may be of great importance socially or politically. But equality is, in its original context, more than just an expression of sameness. It suggests also a possibility of being either more than or less than. I can be the same age as you, but if I were not, I should be either older than you, or younger. This is always the case in mathematics. The law of trichotomy holds, that if two things are not equal, then one is greater, in the relevant respect, than the other, and the difference can itself be measured. With human beings, however, there are rather few respects in which we can be properly measured. Age, height and weight apart, the ascription of most numerical measures is a dubious affair. At one time psychologists were confident that they could measure intelligence, and economists still purport to measure wealth, but the ascriptions they actually make do not seem to deserve the confidence called for..

In Epiphany Term, 1942, C.S. Lewis delivered the Riddell Memorial Lectures in the Physics Lecture Theatre, King's College, Newcastle, which was then a constituent college of the University of Durham. The Riddell Memorial Lectures were founded in 1928 in memory of Sir John Buchanan Riddell of Hepple, onetime High Sheriff of Northumberland, who had died in 1924. His son, Sir Walter, was, like his father, a devout Christian, active throughout his life in public affairs. He was Fellow, and subsequently Principal, (...) of Hertford College, Oxford, and Secretary, and subsequently Chairman, of the University Grants Committee---at a time when the interventions of the UGC in academic affairs were entirely benign. I myself have a special personal interest in the founder of the Riddell Lectures. Sir Walter and my father were contemporaries at Oxford and close friends. Owing to his untimely death I never knew him, though I am credibly assured that he must have viewed me when I was taken to Hepple in a Moses' basket at the age of six months. In being invited to give this lecture on the Riddell Lectures, I am not only honoured but enabled to discharge a debt of family.. (shrink)

Arguments have been much misunderstood. Not only has it been assumed that they must be deductive, but it has been assumed also that, although often expressed in loose and elliptical form, they must be capable, if they are valid at all, of being expressed with absolute precision, as a set of necessary and sufficient conditions for the action in question to be appropriate. Mathematical arguments are capable of being stated precisely, and it has long been a reproach to workers in (...) other disciplines that they do not manage to achieve equal precision in their work. The assumption is made that absolute precision is in principle available, and it is only a lack of rigour by practitioners in the non-mathematical disciplines that prevents them casting their arguments in satisfactory form, and the philosopher should, therefore, reconstruct arguments to conform with these requirements, evaluating those that do, and rejecting any that do not.

It would be improper for a President to play safe. After two years of curbing my tongue and not making all sorts of observations that have sprung to my mind, in order to let you have an opportunity of having your say, I am now off the leash. And whereas mostly in academic life it is appropriate to adopt a prudential strategy, and not say anything that might be wrong, I owe it to you on this occasion to play a (...) maximax strategy, to speak out and say what I really think, being willing to run the risk of being wrong in order not to forgo the chance of actually being right in an area of the philosophy of science which must, I think for ever, be largely a matter of metaphysical speculation.

XLRI, in association with a few Tata Group companies, established the XLRI-JRD Tata Foundation in Business Ethics in 1991 to mark their long-standing commitment and contribution to business ethics in India. The foundation seeks to address this by publicly affirming the urgent need for ethics in business and the need to bring about a conducive culture in which it can thrive.

This article traces the multiple enactments of sex in clinical practices of transgender medicine to argue against the presumed singularity of ‘transexuality’. Using autoethnography to analyse my own experience as a trans patient, I describe my clinical encounters with doctors, psychiatrists and surgeons in order to theorise sex as multiple. Following recent developments in science and technology studies (STS) that advance the work of Judith Butler on sex as performatively reproduced, I use a praxiographic approach to argue that treatment practices (...) produce particular iterations of what sex (and transexuality) ‘is’ and how these processes limit and foreclose other trans possibilities. I consider the ethical, political and material-discursive implications of treatment practices and offer a series of reflections about the effects and effectiveness of current clinical practices and the possibilities for intervening in such processes in order that, following Annemarie Mol, we might (re)make sex (and transexuality) differently.
