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.

This paper outlines Lewis’s favoured foundational account of linguistic representation, and outlines and briefly evaluates variations and modifications. Section 1 gives an opinionated exegesis of Lewis’ work on the foundations of reference—his interpretationism. I look at the way that the metaphysical distinction between natural and non-natural properties came to play a central role in his thinking about language. Lewis’s own deployment of this notion has implausible commitments, so in section 2 I consider variations and alternatives. Section 3 briefly considers a (...) buck-passing strategy involving fine-grained linguistic conventions. (shrink)

That space and time should be integrated into a single entity, spacetime, is the great insight of Einstein's special theory of relativity, and leads us to regard spacetime as a fundamental context in which to make sense of the world around us. But it is not the only one. Causality is equally important and at least as far as the special theory goes, it cannot be subsumed under a fundamentally geometrical form of explanation. In fact, the agent of propagation of (...) causal influence is electromagnetic radiation. In this examination, the authors find support for a rationalist approach to physics, never neglecting experimentation, but rejecting a simple empiricist or positivist view of science. (shrink)

According to the thought experiment most commonly used to argue against reliabilism, Mr. Truetemp is given an unusual but reliable cognitive faculty. Since he is unaware of the existence of this faculty, its deliverances strike him as rather odd. Many think that Truetemp would not have justified beliefs. Since he satisfies the reliabilist conditions for justified belief, reliabilism appears to be mistaken. I argue that the Truetemp case is underdescribed and that this leads readers to make erroneous assumptions about Truetemp's (...) epistemic situation. After examining empirical studies of actual subjects who, like Truetemp, have received new perceptual faculties, I show that Truetemp must have been endowed with all of the reorganized neural circuitry and cognitive skills that subjects with new perceptual faculties normally acquire during a long and difficult process of adaptation and development. When readers realize how much more the designers of Truetemp's new faculty had to do than simply slip an artificial device under Truetemp's scalp, I find that they no longer think his beliefs would be unjustified. Because the thought experiment fails to support anti-reliabilist intuitions when further details of the case are made explicit, the Truetemp thought experiment does not constitute a clear and decisive counterexample to reliabilism.

The issue is obscured by the fact that the word `space' can be used in four different ways. It can be used, first, as a term of pure mathematics, as when mathematicians talk of an `n-dimensional phase-space', an `n-dimensional vector-space', a `three-dimensional projective space' or a `twodimensional Riemannian space'. In this sense the word `space' means the totality of the abstract entities-the `points'-implicitly defined by the axioms. There is no doubt that there exist, iii this sense, non-Euclidean spaces, because all (...) that is claimed by such an assertion is that sets of non-Euclidean axioms constitute possible implicit definitions of abstract entities, that is to say that some sets of non-Euclidean axioms are consistent. If Kant or any other philosopher had denied this, he would have been wrong; but Kant himself took care not to deny it, 2 and there is little reason to suppose that any philosopher concerned about space has been using the word in this, the pure mathematician's, sense.

Equality is the great political issue of our time. Liberty is forgotten: Fraternity never did engage our passions: the maintenance of Law and Order is at a discount: Natural Rights and Natural Justice are outmoded shibboleths. But Equality—there men have something to die for, kill for, agitate about, be miserable about. The demand for Equality obsesses all our political thought. We are not sure what it is—indeed, as I shall show later, we are necessarily not sure what it is—but we (...) are sure that whatever it is, we want it: and while we are prepared to look on frustration, injustice or violence with tolerance, as part of the natural order of things, we will work ourselves up into paroxysms of righteous indignation at the bare mention of Inequality.

In the latter half of the twentieth century, developed countries of the world have made tremendous strides in organ donation and transplantation. However, in this area of medicine, Japan has been slow to follow. Japanese ethics, deeply rooted in religion and tradition, have affected their outlook on life and death. Because the Japanese have only recently started to acknowledge the concept of brain death, transplantation of major organs has been hindered in that country. Currently, there is a dual definition of (...) death in Japan, intended to satisfy both sides of the issue. This interesting paradox, which still stands to be fully resolved, illustrates the contentious conflict between medical ethics and medical progress in Japan. (shrink)

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.

The purpose of this essay is to stimulate academic discussion about the ethical justification of using human primordial stem cells for tissue transplantation, cell replacement, and gene therapy. There are intriguing alternatives to using embryos obtained from elective abortions and in vitro fertilisation to reconstitute damaged or dysfunctional human organs. These include the expansion and transplantation of latent adult progenitor cells.

While the UK Home Office’s proposals to preventively detain people with what it has called dangerous severe personality disorder have been subjected to debate and criticism the deeply troubling jurisprudential issues in these proposals have not yet entered into public debate in a way that their seriousness deserves.1 It is good that a commentator as well known as Professor Szasz is speaking out on this issue.Professor Szasz focuses upon a crucial question by calling into question the medicalisation of terms like (...) dangerousness and mental illness.2 There is a great temptation for legislators and the public to treat these terms as if they are purely scientific terms and to think of risk assessment as a precise science. I don’t share Professor’s Szasz’s worry about how psychiatry is using these terms but I think there are some important questions about how these concepts function in the public sphere.This issue is important enough to justify the use of some rhetorical claims because such claims can serve to bring out what are neglected and important issues. In raising the following objections I am not attempting to refute the message that is in Szasz’s article or to say that he is not making an important point but rather to attempt to sharpen the issues and to suggest ways that we can respond to Professor Szasz’s challenge.Psychiatry has progressed in a number of ways since Professor Szasz wrote The Myth of Mental Illness.3 The science is much better, we have much better medications, and psychiatrists are acutely aware of the tension between treating their patient and their obligations to the public interest.So when Professor Szasz says: “Psychiatrists offer to relieve the disturbed person of the burden of coping ….

My sights in this paper are trained on facts. Most people think that they know what facts are; that while their friends often, and themselves occasionally, are ignorant of the facts, at least they know what sort of things facts are---they can recognise a fact when they see it. Facts, in the popular philosophy of today, are good, simple souls; there is no guile in them, nor any room for subjective bias, and once we have made ourselves acquainted with them, (...) we have reached the beginning and summit of all wisdom.

§1. The origins of recursion theory. In dedicating a book to Steve Kleene, I referred to him as the person who made recursion theory into a theory. Recursion theory was begun by Kleene's teacher at Princeton, Alonzo Church, who first defined the class of recursive functions; first maintained that this class was the class of computable functions ; and first used this fact to solve negatively some classical problems on the existence of algorithms. However, it was Kleene who, in his (...) thesis and in his subsequent attempts to convince himself of Church's Thesis, developed a general theory of the behavior of the recursive functions. He continued to develop this theory and extend it to new situations throughout his mathematical career. Indeed, all of the research which he did had a close relationship to recursive functions.Church's Thesis arose in an accidental way. In his investigations of a system of logic which he had invented, Church became interested in a class of functions which he called the λ-definable functions. Initially, Church knew that the successor function and the addition function were λ-definable, but not much else. During 1932, Kleene gradually showed1 that this class of functions was quite extensive; and these results became an important part of his thesis 1935a. (shrink)

Justice has always been regarded as one of the fundamental political virtues. No association of human individuals could subsist, says Hume, “were no regard paid to the laws of equity and justice”, and nearly every thinker who has turned to consider human society, has reached the same conclusion. Yet we are not at all clear what justice is, nor why it is so important. There are many other ideals which a society may cherish, and often reformers have felt impatient of (...) having to compromise their aims merely for the sake of justice, and have not seen why the claims of justice should in any way override other political goods. I shall try to show why justice is, along with liberty, a peculiarly fundamental ideal, which is not merely co-ordinate with other ideals a society may value; but also that this notwithstanding, considerations of justice are not all-sufficient, and do not, and should not, always override all other political ideals.

There are currently two main philosophical theories of perception - Direct Realism and the Representative Theory. The former is supported by most contemporary philosophers, whereas the latter forms the groundwork for most scientific theories in this area. The paper describes a recent experiment involving retinal and cortical rivalry that provides strong empirical evidence that the Direct Realist theory is incorrect. There are of course a large number of related experiments on visual perception that would tend to lead us to the (...) same conclusion, but the experiment described in this paper does so in a singularly direct and straightforward manner. Often the most telling experiments are the simplest. (shrink)

A plural referring expression (‘the Fs’ or ‘Tom, Dick and Harriet’) may be used to refer either distributively, saying something which applies to each of the Fs individually, or collectively, to the Fs taken as a single totality. Predicate Logic has to analyse both uses in terms of singular reference, treating them quite differently in so doing; but we think of such an expression as functioning in basically the same way in both kinds of use. This understanding can be vindicated (...) if we recognise that what a plural referring expression picks out is not either an aggregate simpliciter or a set, but a plurality– an aggregate taken relative to a principle for individuating its constituents; this admits of being seen either as many things or as one. In any given case, it is the nature of what is being said about the plurality which tells us whether the reference to it is to be taken as distributive, collective, or a combination of the two. Talk about pluralities is extensional. Augmenting Predicate Logic to accommodate the distinctive inference‐pattern associated with distributive plural reference is simple – and arguably necessary, to cope with cases in which distributive and collective reference are essentially combined (e.g., attributions of concerted action).

NICE, the draft fertility guideline and dodging the big question: should fertility treatment be provided by the NHS?In August of this year the National Institute for Clinical Excellence made its draft guideline on fertility treatment available for consultation.1 As has been widely reported in the media the draft guideline recommends that the National Health Service should provide publicly funded fertility treatment in a consistent way across England and Wales. The guideline recommends that three cycles of IVF should be available when (...) “The woman is within the optimal range for in vitro fertilisation and there is an appropriately diagnosed cause of infertility of any duration, or unexplained infertility of at least three years’ duration .Those who need fertility treatment will celebrate the guideline, as will many fertility clinics. The guideline does not, however, address key questions that will be obvious to many. Is fertility treatment the kind of thing that ought to be available on the NHS? Will the inevitable increase in demand mean that resources are directed away from other services? Is fertility treatment really the same kind of intervention as heart or hip replacement surgery?My view is that there are good reasons for doing what we can to help people access fertility services. Most of us will start a family and for those of us who do it is probably the most important of all of our life projects. Given that social status and wealth can be significant obstacles to many of the things that people would like to do with their lives, the fact that most of us are able to pursue this important life project is good from an egalitarian ….

IT is ungenerous to pick holes in The Concept of Law. It is a great work. Its clarity is luminous, and its argument sustained and convincing. Hart is eminently successful in rescuing the concept of law from the Legal Realists, the Positivists, and the Formalists, who attempt to straitjacket it within schemata which are too narrow or too vague to give an adequate elucidation of it. But sometimes Hart is not carried along by his arguments as far as he should. (...) He makes too many concessions to his opponents, and his own account of the law is, in consequence, too formalist, in spite of having himself adduced cogent considerations elsewhere for rejecting the purely formalist line of argument. The rule of recognition, although important, is not fundamental. We should, rather, see law as a social phenomenon, to be distinguished from other social phenomena, but intelligible only in a social context, and not-as lawyers are too ready to suppose-an autonomous discipline which can be explained and understood entirely in its own terms.

The problem with which I wish to deal in this paper is the problem of singular reasons in the humanities, whether they exist, or rather, whether they can exist: for it would seem that the word “reason” carried with it some idea of generality, so that the phrase “singular reason” was a contradiction in terms, a specification which could never be fulfilled. But humanists are always sensing the singularity of their studies: and the philosopher wondering about the nature of humane (...) thinking either must conclude that it is really only inadequate science, its singularity being the mark of the fact that we never really have an adequate basis for any of our generalizations, an unfortunate reminder that the whole structure is built on the shakiest of inductive foundations; or , if he is unwilling to allow that humanists are just bad, or at least amateur, scientists, he is tempted to vindicate the rationality of their reasoning by inventing a special faculty of particular ratiocination which is able to perceive particular truths—the intuition of the moralists or the insight of the Collingwoodian mode.

This paper focuses on perception and surveys the scientific evidence that the theory of direct realism adopted by most contemporary philosophers is incorrect. This evidence is provided by experiments on the spatial and temporal "filling-in" of percepts. It also examines the myth of the projection of sensations. The conclusion is that we do not perceive the world as it actually is, but as the brain computes it most probably to be.

*This work has turned into a bigger project, and some of it is published in "Lewis on reference".* Some things, argues Lewis, are just better candidates to be referents than others. Even at the cost of attributing false beliefs, we interpret people as referring to the most interesting kinds in their vicinity. How should this be accounted for? In section 1, I look at Lewis’s interpretationism, and the reference magnetism it builds in (not just for ‘perfectly natural’ properties, but for (...) certain kinds of auxiliary apparatus). In section 2, I draw on (Field, 1975) to argue that what properties are reference magnetic may be an ultimately conventional matter—though in the Lewisian setting, there may be an objectively best conventional choice to make. But Lewis’s own account has implausible commitments, so in section 3 I consider variations and alternatives, all of which have problems. In section 4, I look in more detail at eligibility-based interpretationism that do not appeal to naturalness, arguing that there are credible metasemantic theories of this form. (shrink)

Professor Braithwaite’s inaugural lecture, here published in book form,1 is a trial run at a Platonic definition of the concept of dianemetic justice; or, as he himself would put it, a rational reconstruction of the concept “sensible-prudent-and-fair”. Aristotle left it that dianemetic justice was an equality and a matter of ratios. A just distribution of őoα µεριστ? τoς κoινωνoσι τς πoλιτείαѕ2 was one in which each had an equitable share, no one having either more or less than he should. Professor (...) Braithwaite goes further and replaces Aristotle’s ordered scale of the-more-and-the-less in which only imprecise and unhelpful answers could be given, by a numerical scale in which he can frame the question “Exactly how much is a fair share?” and propound his s own solution.

*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)

In an otherwise convincing article Mr. T. P. Wiseman argues that this passage ‘seems to mean that L. Memmius and Q. Pompeius were principes, i.e. outstanding orators, and that they were not among those who spoke in their own defence in 90 B.C.’. But he rightly refuses to believe that Cicero can have intended this, since, apart from other considerations, it is clear from Cicero's previous references to Memmius and Pompeius that he did not consider them to be outstanding orators.

This paper examines the life and work of T. C. Chamberlin, a prominent glacial geologist who developed an interest in interdisciplinary earth science. His work on the geological agency of the atmosphere informed his understanding of climate change and other terrestrial phenomena and led him to propose a new theory of the formation of the Earth and the solar system.Chamberlin's graduate seminar at the University of Chicago in 1896 contained all the themes that informed his research programme over the next (...) three decades. These included the carbon dioxide theory of climate change in its relationship to diastrophism and oceanic circulation, the role of water vapour feedbacks in the climate system, and the relationship between multiple glaciations, the climate system, and the formation of the planet.
