Argues against D. Hume's (1825) treatise "Of Miracles," which is often used to disprove the existence of psi. Hume states that a miracle is a violation of the laws of nature which are proved to be true by common experience, and that the only sufficient testimony for a miracle would be testimony whose falsehood would be even more miraculous than the miracle itself. The primary objections to Hume's argument are that (1) it is tautological, since it presupposes the nonexistence of (...) miraculous events, and (2) as a metaphysical statement, it is inappropriate when considering empirical evidence, which should be judged by its own rule.

Reduction has long been a favourite method of analysis in all areas of philosophy, but in recent years there has been a reaction against it. The contributors to this volume examine the motivations for such anti-reductionist views and assess their coherence and success in a number of fields.

There is as yet no settled consensus as to what makes a term a logical constant or even as to which terms should be recognized as having this status. This essay sets out and defends a rationale for identifying logical constants. I argue for a two-tiered approach to logical theory. First, a secure, core logical theory recognizes only a minimal set of constants needed for deductively systematizing scientific theories. Second, there are extended logical theories whose objectives are to systematize various (...) pre-theoretic, modal intuitions. The latter theories may recognize a variety of additional constants as needed in order to formalize a given set of intuitions. (shrink)

Background and objectives: There are few insights from sub-Saharan Africa on research participants’ experiences of the informed consent process, particularly in the context of randomised controlled trials, where issues of randomisation and the use of placebos may be confusing concepts for participants. This study investigated the knowledge and perceptions of the informed consent process among individuals participating in influenza vaccine trials in two disadvantaged communities in South Africa.Method: Four to 12 months after completion of the trials, participants were contacted to (...) return to participate in the informed consent study. The semistructured questionnaire administered to assess recall of trial procedures and the informed consent process covered key issues including: purpose of the study; awareness that the study was not part of routine treatment; voluntary nature of participation and freedom to withdraw; randomisation; placebos; and remuneration.Results: A total of 334 participants completed the questionnaire. Only 21% were able to recall that they were allocated randomly to the different treatment arms. Only 19% of those involved in the placebo controlled study had interpreted the concept of placebo as an inactive medication.Conclusion: Although a good general recall of trial concepts was demonstrated, only a small proportion of the participants correctly interpreted and recalled the concepts of randomisation and placebos. Informed consent in this and similarly disadvantaged communities may often be inadequate and new ways to improve understanding of the research process should be explored. (shrink)

Marx’s concept of value has been subject to significant criticism. Robinson argues that the concept is awkward and obscure, as it is meant to explain the prices of commodities and thus must be a kind of price, but it is not. Consequently, Robinson holds that the concept of value makes no sense. Furthermore, according to Harvey, Marx in the Grundrisse confuses value with price. It seems to me that both Robinson’s criticism and Harvey’s exegesis are based on serious misunderstandings. In (...) this article, I first unpack Marx’s criticism of Darimon’s proposal concerning time chits. The upshot is that, for Marx, production relations enjoy a priority, and a monetary reform like Darimon’s cannot fulfill the function of revolutionary change. So, time chits become a triviality. Second, I suggest a reconstruction of what I call Marx’s “nonconvergency thesis.” The thesis states that there is a supervenience between value and price. Marx says that Darimon is ignorant about this thesis, and his proposal relies on the delusion that the two are convergent. Therefore, I maintain that Harvey’s claim is misleading, as he overlooks the nonconvergency thesis articulated in the Grundrisse. And Robinson’s condemnation of the concept of value should be dismissed because her understanding is very much the same as Darimon’s, in that she ignores the two-layered ontological structure between value and price.

I compare the epistemic culture of Wikipedia with the epistemic culture of science, with special attention to the culture of collaborative research in science. The two cultures differ markedly with respect to (1) the knowledge produced, (2) who produces the knowledge, and (3) the processes by which knowledge is produced. Wikipedia has created a community of inquirers that are governed by norms very different from those that govern scientists. Those who contribute to Wikipedia do not ground their claims on their (...) reputations as knowers, for they stand to lose nothing if and when their contributions are found to be misleading or false. And the immediacy of the medium encourages gossip and jokes. Hence, though we have some reason to believe that an invisible hand aids scientists in realizing their epistemic goals, we cannot ground our confidence in what is reported on Wikipedia on the fact that an invisible hand ensures quality. Nor is the information on Wikipedia aptly justified in a manner similar to the way testimony can be justified. (shrink)

This “open letter” to Christopher Boorse is a response to his influential naturalist analysis of disease from the perspective of linguistic-analytic value theory. The key linguistic-analytic point against Boorse is that, although defining disease value free, he continue to use the term with clear evaluative connotations. A descriptivist analysis of disease would allow value-free definition consistently with value-laden use: but descriptivism fails when applied to mental disorder because it depends on shared values whereas the values relevant to mental disorders are (...) highly diverse. A part-function analysis, similarly, although initially persuasive for physical disorders, fails with the psychotic mental disorders because these, characteristically, involve disturbances of the rationality of the person as a whole. The difficulties encountered in applying naturalism to mental disorders point, linguistic-analytically, to the possibility that there is, after all, an evaluative element of meaning, deeply hidden but still logically operative, in the concept of disease.

This paper defends what the philosopher Merleau Ponty coins 'the imaginary texture of the real'. It is suggested that the imagination is at work in the everyday world which we perceive, the world as it is for us. In defending this view a concept of the imagination is invoked which has both similarities with and differences from, our everyday notion. The everyday notion contrasts the imaginary and the real. The imaginary is tied to the fictional or the illusory. Here it (...) will be suggested, following both Kant and Strawson, that there is a more fundamental working of the imagination, present in both perception and the constructions of fictions. What Kant and Strawson failed to make clear, however, was that the workings of the imagination within the perceived world, gives that world, an affective logic. The domain of affect is that of emotions, feelings and desire, and to claim such an affective logic in the world we experience, is to point out that it has salience and significance for us. Such salience suggests and demands the desiring and sometimes fearful responses we make to it; the shape of the perceived world echoed in the shapes our bodies take within it. (shrink)

Couples should not be allowed to select either for or against deafnessRecently, a US couple deliberately attempted to ensure the birth of a deaf child via artificial insemination.1 In opposing this action, I wish to focus on one argument they employ to support it, namely that in trying to have a deaf child, the women see themselves as no different from parents trying to have a girl. Girls can be discriminated against the same as deaf people and “black people have (...) harder lives”, one of them argues. They compare themselves to a minority group.2In using this argument to justify their attempt to secure the birth of a deaf child, they make four claims: It is not wrong to deliberately try to have a child who is expected to experience harm when the harms the child will experience are socially imposed. As a group experiencing socially imposed harms, the deaf are to be understood as a minority group. Women and people of colour also experience social harms, and are to be understood as minority groups. Because the deaf, women, and people of colour are all groups experiencing socially imposed harms, distinctions should not be made between attempts to have a child who will be a member of one of these groups.In reply, I will advance two arguments. First, I will argue that this couple’s decision is inherently just. Here I will acknowledge that this couple’s position draws a great deal of strength from its appeal to the experiences of women. My second argument will contend, however, that despite the reasonableness of this choice, the intentional selection of deaf children is indefensible. Granting this couple’s contestable assertion that the deaf ought to be understood as a minority cultural group, allowing individuals to secure the birth of deaf …. (shrink)

I present a history of Kuhn’s discovery of paradigms, one that takes account of the complexity of the discovery process. Rather than emerging fully formed in Structure , the concept paradigm emerged through a series of phases. Early criticism of Structure revealed that the role of paradigms was unclear. It was only as Kuhn responded to criticism that he finally articulated a precise understanding of the concept paradigm. In a series of publications in the 1970s, he settled on a conception (...) of a paradigm as a concrete exemplar that functions as a guide to future research. (shrink)

This research examines the methodologies employed by cognitive psychologists to study “false memory,” and assesses if these methodologies are likely to facilitate scientific progress or perhaps constrain the conclusions reached. A PsycINFO search of the empirical publications in cognitive psychology was conducted through January, 2004, using the subject heading, “false memory.” The search produced 198 articles. Although there is an apparent false memory research bandwagon in cognitive psychology, with increasing numbers of studies published on this topic over the past decade, (...) few researchers have studied false memory as the term was originally intended—to specifically refer to planting memory for an entirely new event that was never experienced in an individual’s lifetime. Cognitive psychologists interested in conducting research relevant to assessing the authenticity of memories for child sexual abuse should consider the generalizability of their research to the planting of entirely new events in memory.

I challenge Gareth Eaton’s recent claim that Theodore Richards should be counted among the discoverers of isotopes. In evaluating Eaton’s claim, I draw on two influential theories of scientific discovery, one developed by Thomas Kuhn, and one developed by Augustine Brannigan. I argue that though Richards’ experimental work contributed to the discovery, his work does not warrant attributing the discovery to him. Richards’ reluctance to acknowledge isotopes is well documented. Further, the fact that he made no claim to having made (...) the discovery also undermines Eaton’s argument. (shrink)

I Propose to re-explore here some aspects of a very shop-worn question: ‘Was Hobbes in any sense an atheist?’ Three centuries ago, Hobbes's personal security in part depended on the way his contemporaries answered this question; today, the validity of several current accounts of his philosophy are similarly bound up with it. These accounts vary extraordinarily, all the way from Polin's confident assertion that ‘ pour qui sait lire entre les lignes, … c'est ľatheísme qui triomphe implicitement ’, to Taylor's (...) equally firm belief that ‘a certain kind of theism is necessary to make [Hobbes's] theory work.’ 1 And now the latest of the Taylorians, Prof. Howard Warrender, has published his book The Political Philosophy of Hobbes , in which Hobbes's statements regarding the place of God are again treated as an essential part of his theory; and the charge explicitly made, that there are no sound grounds for regarding them as ‘the product of confusion or pretence on Hobbes's part’.

We examined unconscious priming in a stem-completion task with both identity and form-related primes. Participants were given exclusion instructions to avoid completing a stem with a briefly flashed masked word . In Experiment 1, priming of around 7% occurred for both identity and form-based primes at a 33 ms exposure duration. When examining only trials in which the participants failed to identify the prime, this effect increased to 12% for identity primes, but remained the same for form-based primes. In Experiment (...) 2, priming without prime identification was 9% for identity primes, 4% for homophone primes, and 3% for orthographic control primes. Although identity priming was greater than form priming in both experiments, regression analyses revealed that orthographic and phonological overlap alone between the flashed primes and targets could completely account for unconscious identity priming. Hence, we conclude that masked words may only activate their sublexical orthographic and phonological representations and not their lexical representations. (shrink)

Clinician gate-keeping is the process whereby healthcare providers prevent access to eligible patients for research recruitment. This paper contends that clinician gate-keeping violates three principles that underpin international ethical guidelines: respect for persons or autonomy; beneficence or a favourable balance of risks and potential benefits; and justice or a fair distribution of the benefits and burdens of research. In order to stimulate further research and debate, three possible strategies are also presented to eliminate gate-keeping: partnership with professional researchers; collaborative research (...) design and clinician education.

Objectives—To investigate the factors considered by staff, and the practicalities involved in the decision making process regarding the withdrawal or withholding of potential life-sustaining treatment in a children's hospital. To compare our current practice with that recommended by the Royal College of Paediatrics and Child Health guidelines, published in 1997.Design—A prospective, observational study using self-reported questionnaires.Setting—Tertiary paediatric hospital.Patients and participants—Consecutive patients identified during a six-month period, about whom a formal discussion took place between medical staff, nursing staff and family regarding (...) the withholding or withdrawal of potentially life-sustaining treatments. The primary physician and primary nurse involved in the discussion were identified.Method—Two questionnaires completed independently by the primary physician and nurse.Results—Twenty-two patients were identified . In 20 cases treatment was withdrawn or withheld, in two cases treatment was continued. Nursing staff considered family wishes and family perceptions of patient suffering as significantly more important factors in decision making than medical staff, who considered prognostic factors as most important. In only two cases were the patient's expressed wishes apparently available. In most cases staff considered the patient's best interests were served and the process would not be enhanced by the involvement of an independent ethics committee. The exceptions were those cases in which treatment was continued following disagreement between parties.Conclusions—Our current practice is consistent with that recommended by the RCPCH. The contribution of the patient, provision of staff counselling and general practitioner involvement were identified as areas for improvement. (shrink)

Quentin Skinner's The Foundations of Modern Political Thought is primarily of interest to philosophers not for its excellent account of European thought about the state but for the self–conscious philosophy which has gone into it. It is a rare historian who pauses to get his philosophy in order before he embarks on a major enterprise, though such a policy is possibly less unusual in intellectual history than in other fields. In Skinner's case, however, this order of doing things has been (...) pushed so far that he counts as a philosopher in his own right, rather than as merely someone who is unusually careful to think about what he is doing. The publication of this major work thus provides a convenient opportunity to make a few remarks about the relation between historical theory and practice. (shrink)

I draw attention to one of the most important sources of Kuhn’s ideas in Structure of Scientific Revolutions. Contrary to the popular trend of focusing on external factors in explaining Kuhn’s views, factors related to his social milieu or personal experiences, I focus on the influence of the books and articles he was reading and thinking about in the history of science, specifically, sources in the history of chemistry. I argue that there is good reason to think that the history (...) of chemistry had a profound influence on Kuhn’s thinking, and what is remarkable is that this has eluded our attention for so long. I also argue that his interest in the history of chemistry was due to the influence of James B. Conant and Leonard Nash. (shrink)

Externalism holds that the individuation of mental content depends on factors external to the subject. This doctrine appears to undermine both the claim that there is a priori self-knowledge, and the view that individuals have privileged access to their thoughts. Tyler Burge's influential "inclusion theory of self-knowledge" purports to reconcile externalism with authoritative self-knowledge. I first consider Paul Boghossian's claim that the inclusion theory is internally inconsistent. I reject one line of response to this charge, but I endorse another. I (...) next suggest, however, that the inclusion theory has little explanatory value. (shrink)

Kant's system of Transcendental Idealism may be regarded, in the contemporary philosophical perspective, as concerned with the problem whether any linguistic or conceptual system can be regarded as adequately explained in terms of the facts which the system organises. ‘ Transcendental ’ may be understood as what is ‘ non-reducible ’. Kant seems to hold that a linguistic scheme cannot be reduced to the facts which fall within the scheme, and thus it is transcendental to those facts. Formulated in such (...) terms, the Kantian doctrine does not, apparently , propound anything which is new; that facts are tailored to a linguistic scheme is pretty much a well-known doctrine these days. But then, as we shall see, it does say something new; and when we extract that novel element in it, we shall discover also the positive import in the Kantian term, ‘ Transcendental ’. (shrink)

In "The Logical Form of Action Sentences" Donald Davidson argues that Hans Reichenbach's analysis of action and event sentences is "radically defective." I show that Reichenbach can easily deflect Davidson's objections, thus leaving their respective accounts largely comparable.

I challenge Hacking's characterization of Kuhn's constructionism. I argue that Kuhn does not believe that nature has no joints. Rather, Kuhn believes there is no unique correct way to cut nature into kinds. I also argue that Kuhn is not an externalist. He believes that disputes in science are resolved on the basis of a consideration of the epistemic merits of the theories. Subjective factors merely ensure that competing theories are developed, and the strengths and weaknesses of the theories are (...) exposed. Epistemic considerations are what ultimately lead to consensus in a research community. (shrink)

Since the earliest Ancient Greek written records from the Mycenaean palaces (ca. 1450–1200 BC) contain no laws, contracts, or judicial decisions, some scholars have considered them unsuitable evidence for legal historical study. Yet this large body of administrative documents reveals much about the operation of the land regime and the interaction of property relations with the central power of the palaces. This article offers a treatment of the relationship between structures in language and normativity in the administrative records relating to (...) land from Late-Bronze-Age Pylos, in particular focussing on a family of textual formulae constructed with the preposition _pa-ro_, which represents a derivative proprietary relation. By focussing on how the records represent the land regime through the use of this formula, and what inconsistencies in its use may tell us, this article explores how we can analyse textual strategies towards an understanding of the system of order in documentary sources. While the tablets are not formally ‘legal’ or normative sources, a study of strategic patterns in the structure of the texts, as well as their inconsistencies and limitations, together shows that normative and legal relations are indeed represented in the records, but appear to be more complex than what is written down. The technical language used by the Mycenaean administrators does not construct a perfectly applied system of abstractions, which has consequences for our understanding of power in the period, perhaps indicating that the complicated sphere of land relations operated partly beyond the palatial system of order. Through this case study this article proposes a method for a more critical approach to normativity in documentary records more generally. The approach outlined here for critically analysing formulae which carry legal meanings may be applied in other contexts using the evidence of ‘practice’, which has often been sidelined by legal historians in favour of normative or formal legal texts.
