Intuitively, there is a difference between knowledge and mere belief. Contemporary philosophical work on the nature of this difference has focused on scenarios known as “Gettier cases.” Designed as counterexamples to the classical theory that knowledge is justified true belief, these cases feature agents who arrive at true beliefs in ways which seem reasonable or justified, while nevertheless seeming to lack knowledge. Prior empirical investigation of these cases has raised questions about whether lay people generally share philosophers’ intuitions about these (...) cases, or whether lay intuitions vary depending on individual factors (e.g. ethnicity) or factors related to specific types of Gettier cases (e.g. cases that include apparent evidence). We report an experiment on lay attributions of knowledge and justification for a wide range of Gettier Cases and for a related class of controversial cases known as Skeptical Pressure cases, which are also thought by philosophers to elicit intuitive denials of knowledge. Although participants rated true beliefs in Gettier and Skeptical Pressure cases as being justified, they were significantly less likely to attribute knowledge for these cases than for matched true belief cases. This pattern of response was consistent across different variations of Gettier cases and did not vary by ethnicity or gender, although attributions of justification were found to be positively related to measures of empathy. These findings therefore suggest that across demographic groups, laypeople share similar epistemic concepts with philosophers, recognizing a difference between knowledge and justified true belief.

Many approaches to addressing labour injustices—shortfalls from minimally decent wages and working conditions— focus on how governments should orient themselves toward other states in which such phenomena take place, or to the firms that are involved with such practices. But of course the question of how to regard such labour practices must also be faced by individuals, and individual consumers of the goods that are produced through these practices in particular. Consumers have become increasingly aware of their connections to complex (...) global production processes that often involve such injustice. For example, activist campaigns have exposed wrongful harm in factories producing clothes, shoes and mobile phones and farms producing coffee, tea and cocoa. These campaigns have promoted the message to ordinary people that by becoming connected to unjust labour practices through their purchasing behaviour, they acquire special additional moral responsibilities to contribute to reforming such practices, or to address the hardships suffered by the victims of the wrongdoing that result from them. The moral significance of the responsibilities of individual consumers has not, however, received much analytical scrutiny. Why should we believe that there are such responsibilities? And if there are such responsibilities, what are their grounds? How stringent are the responsibilities triggered by such connections? Finally, what are the implications of such responsibilities—the courses of action that they prescribe or proscribe? The activists who assert special ethical responsibilities for consumers have promoted many particular courses of action, but have seldom articulated the grounds of these responsibilities or explained why they should be taken to be stringent. And moral and political theorists have not devoted much focussed attention to this issue. For the consumer who is concerned to act in a morally permissible way, this presents a troubling practical challenge regarding the goods they may (or may not) purchase, and the moral relevance of their consumption choices more generally. While we cannot address all of these pressing questions in this chapter, we try to make some headway with them by discussing two general approaches to the question of how individuals should conceive of their responsibilities with respect to such practices, taking as our starting point the recent work of the late Iris Marion Young—the most sustained treatment of this topic by a prominent political theorist. In a series of influential articles and a posthumously published book, Young articulated an approach to conceiving of individual responsibilities to address labour injustices—the social connection model—at home and abroad. She also argued that an alternative model—the liability model—which she claimed had dominated discourse on this topic, suffered from very serious flaws. In a critical vein, we will argue that Young’s arguments against the liability model are not convincing, and that the alternative she proposes is itself vulnerable to some damaging objections. We also find, however, that the liability model would need to be extended in various ways to provide an adequate account of individual responsibility to address shortfalls from minimally decent wages and working conditions, and we begin the task of sketching an extended framework.

Many nongovernmental forms of business regulation aim at reducing ethical violations in commerce. We argue that such nongovernmental ethics standards, while often laudable, raise their own ethical challenges. In particular, when such standards place burdens upon vulnerable market participants (often, though not always, SMEs), they do so without the backing of traditional legitimate political authority. We argue that this constitutes a structural analogy to wars of humanitarian intervention. Moreover, we show that, while some harms imposed by such standards are desirable, (...) others are best thought of as a form of collateral damage. We thus look at the well-developed literature on just war theory for inspiration and find that the principles of jus ad bellum and jus in bello contain many insights that can be fruitfully adapted to the case of nongovernmental standard-setting. Consequently, we propose the Ius ad Normam—a set of principles that should guide would-be standard-setters in assessing whether imposing those burdens is ethically justifiable in particular cases. We also discuss how powerful multinational businesses often act simultaneously as standard-takers and standard-setters and explore the normative implications of this dual role. (shrink)

A central task of schooling is to cultivate reasonableness in students. In this chapter we show how the teaching of reasonableness can be practiced successfully in secondary schools, using materials from the Western Australian curriculum. The discussion proceeds in four stages. We first defend the claim that the teaching of reasonable is a key aim of schooling. Here we offer an account of reasonableness, which we take to be both a skill and a disposition. Students learn reasonableness through the practice (...) of specific skills such as open and curious questioning, clarifying, and categorizing, and evaluating the merits of each contribution toward the problem or question under consideration. Reasonableness comes about as a joint commitment between the individual and the group to be honest in their views, to take care of those views, and for everyone to recognize that each member is a partial bearer of truth. Secondly, we discuss the pedagogies that cultivate reasonableness. The Philosophical Community of Inquiry is a natural pedagogy for this purpose. This can be supplemented with the thinking tools approach of Cam’s Twenty Thinking Tools or Harvard Project Zero’s Thinking Routines. In addition, we introduce our own two skill-building exercises, the Reasoning Game and the Argument Game. Thirdly, we show how this approach can be applied not just in Philosophy classes, but in the Humanities and Social Sciences. We argue that our approach brings these subjects to life, it develops understanding and reasonableness, and it bumps up student engagement. Fourthly, we discuss the assessment of reasonableness. In this type of learning environment, the way students perform in the philosophical community of inquiry is the focus of assessment. The desirable qualities of being reasonable become the assessment criteria for an on-balanced judgment about the student. (shrink)

The issue of leadership styles used by school heads and the academic performance of students has recently attracted the attention of the general public and people are exerting energies into research to find its courses and effects. Nkoranza-North district is selected as a result of the fact that the researcher works there and the districts also have two senior high schools for the study. Primarily, the study was to find out the courses and impact of leadership styles on teaching and (...) learning outcomes in the Nkoranza-North district. The study covered a sample size of sixty (60) people comprises of Headmasters, selected teachers and selected students of the two. The researcher employed the descriptive method, while interview schedule and questionnaire were used to gather the information. Frequency and percentage were used to analyse the data. The study also looks at the various leadership styles employed by leaders some of which are Autocratic, Democratic and Laissez-faire. The findings of the study are discussed, conclusion draw and recommendations made. (shrink)

This research determined the correlation between the mindfulness, mental toughness, and motivation of 770 first year and second year college students and their sports involvement in one of the oldest private higher education institutions in the City of Manila. A researcher-made questionnaire was validated and pilot-tested prior to the conduct of the study. The results revealed that most of the respondents were 17 to 19 years old (75.06%) and they described their mindfulness in terms of attention and awareness as “Very (...) High”; their mental toughness in terms of rebound ability, ability to handle pressure, concentration and confidence as “Very High”; their intrinsic motivation as “Very High”; their extrinsic motivation as “High”; their sports involvement in terms of power and performance as ”High”; and their sports involvement in terms of pleasure and participation as ”Very High.”.

This paper gives two complete and elementary proofs that if the speed of light over closed paths has a universal value c, then it is possible to synchronize clocks in such a way that the one-way speed of light is c. The first proof is an elementary version of a recent proof.

We (...) also discuss an old incomplete proof by Weyl which is important from an historical perspective. (shrink)

Quassim Cassam has argued that psychological and epistemological analyses of conspiracy theories threaten to overlook the political nature of such theories. According to Cassam, conspiracy theories are a form of political propaganda. I develop a limited critique of Cassam's analysis.This paper advances two core theses. First, acceptance of conspiracy theories requires a rejection of epistemic authority that renders conspiracy theorists susceptible to co-option by certain political programs while insulating such programs from criticism. I argue that the contrarian nature of conspiracy (...) theories partially accounts for the prominence of such theories in populist movements.Second, the contrarian nature of conspiracy theories partially accounts for their attractiveness, especially among those to whom populism already appeals. I argue that for those who resent what appears from their perspective as the shaping of the epistemic landscape by alien perspectives, conspiracy theorizing may facilitate the reassertion of epistemic autonomy.

The world has surpassed three million deaths from COVID-19, and faces potentially catastrophic tipping points in the global climate system. Despite the urgency, governments have struggled to address either problem. In this paper, we argue that COVID-19 and anthropogenic climate change (ACC) are critical examples of an emerging type of governance challenge: severe collective action problems that require significant individual behavior change under conditions of hyper- partisanship and scientific misinformation. Building on foundational political science work demonstrating the potential for norms (...) (or informal rules of behavior) to solve collective action problems, we analyze more recent work on norms from neighboring disciplines to offer novel recommendations for more difficult challenges like COVID-19 and ACC. Key insights include more attention to (1) norm-based messaging strategies that appeal to individuals across the ideological spectrum or that reframe collective action as consistent with resistant subgroups’ pre-existing values, (2) messages that emphasize both the prevalence and the social desirability of individual behaviors required to address these challenges, (3) careful use of public policies and incentives that make individual behavior change easier without threatening norm internalization, and (4) greater attention to epistemic norms governing trust in different information sources. We conclude by pointing out that COVID-19 and climate change are likely harbingers of other polarized collective action problems that governments will face in the future. By connecting work on norms and political governance with a broader, interdisciplinary literature on norm psychology, motivation, and behavior change, we aim to improve the ability of political scientists and policy makers to respond to these and future collective action challenges.

This research paper assesses the possible relationship between motivation and academic performance of student athletes and utilized a descriptive design as it investigated the association between two constructs (variables) of student athletes, namely their motivation and academic performance. The research is descriptive correlational research with sixty (60) student athlete respondents coming from the various varsity teams in a selected university in the city of Manila. The descriptive nature and design of the study would require that descriptive statistics and measures of (...) association be utilized to analyze the relationship between the two constructs of the study – motivation and academic performance. The (SAMSAQ) was chosen as the research instrument to collate the necessary descriptive data, upon which a correlation analysis through the Pearson was administered. After the statistical analysis, the following were the conclusion of the study: (1) That there was a perfect positive relationship between responses of the student – athletes in the thirty (30) SAMSAQ items and their GPA’s; (2) That the relationship between motivation and academic performance of respondents, as represented by their mean scores of responses and GPA’s respectively are not of the same strength and significance for negatively and positively – structured queries of the SAMSAQ; (3) That the mean scores of responses in negative and positive impact queries of respondents and its relationship with their GPA’s, representatives of the measures of motivation and academic performance are incomparable as the Likert scale is inverted for the negatively structured queries, where behavior adverse to academic performance is sought.

This paper describes the ways in which trolls and bots impede the acquisition of knowledge online. I distinguish between three ways in which trolls and bots can impede knowledge acquisition, namely, by deceiving, by encouraging misplaced skepticism, and by interfering with the acquisition of warrant concerning persons and content encountered online. I argue that these threats are difficult to resist simultaneously. I argue, further, that the threat that trolls and bots pose to knowledge acquisition goes beyond the mere threat of (...) online misinformation, or the more familiar threat posed by liars offline. Trolls and bots are, in effect, fake persons. Consequently, trolls and bots can systemically interfere with knowledge acquisition by manipulating the signals whereby individuals acquire knowledge from one another online. I conclude with a brief discussion of some possible remedies for the problem of fake persons. (shrink)

Particularists maintain that conspiracy theories are to be assessed individually, while generalists hold that conspiracy theories may be assessed as a class. This paper seeks to clarify the nature and importance of the debate between particularism and generalism, while offering an argument for a version of generalism. I begin by considering three approaches to the definition of conspiracy theory, and offer reason to prefer an approach that defines conspiracy theories in opposition to the claims of epistemic authorities. I argue that (...) particularists rely on an untenably broad definition of conspiracy theory. Then, I argue that particularism and its counterpart are best understood as constellations of theses, rather than a pair of incompatible theses. While some particularist theses are highly plausible, I argue that one important particularist thesis is false. The argument for this conclusion draws on the history of false conspiracy theories. I then defend this conclusion against a pair of potential objections. (shrink)

This study investigated the difference in the sports involvement of the first year and second year college students in terms power and performance and pleasure and participation. In a sample of seven hundred seventy first year and second year college student students collected between the months of November to December 2019, in terms of power and performance during sports activities, first year respondents gave an average rating of 3.06 (Agree) while the second-year respondents gave an average rating of 3.07 (agree). (...) The results suggest that the student-respondents were not after winning when they were involved in sports. Furthermore, first year respondents gave the highest mean score of 3.79 (strongly agree) in the item “I want to have fun during sports activities” while the second-year respondents gave the highest mean score of 3.75 (strongly agree) in the item “I believe that even poorly skilled students deserve the right to play”. Moreover, using the t-test at 0.05 level of significance power and performance with a computed t-test value of 1.54 and pleasure and participation with a computed t-test value of 1.170 were both lower than the tabular t-test value of 1.971 with the degree of freedom of 768. Therefore, the null hypothesis was accepted. Thus, there was no significant difference between the first year and second year college students’ sports involvement in terms of power and performance and pleasure and participation. The results suggest that students may be provided with various sports programs for competition or for leisure to foster holistic student development. (shrink)

Despite raising awareness and promoting knowledge and skills-development for education about climate change, efforts by the education sector to promote the development of climate change science literacy in schools is challenged by the nature of climate science. We illuminated the nature of climate science by analysing literature on the nature of science that foregrounds discussions in climate science, and found that climate science involves mostly complex systems and problems; the scope of climate science is vast and interdisciplinary; most issues and (...) problems in climate science are geographic in nature; climate science is characterised by uncertainty and disagreement; and, it is highly politicised. Unless education policymakers and curriculum designers consider these factors when formulating pedagogical intervention frameworks for a more effective and efficient climate change education; nurturing climate change science literacy in schools will be ever more elusive.

Deepfakes pose a multi-faceted threat to the acquisition of knowledge. It is widely hoped that technological solutions—in the form of artificially intelligent systems for detecting deepfakes—will help to address this threat. I argue that the prospects for purely technological solutions to the problem of deepfakes are dim. Especially given the evolving nature of the threat, technological solutions cannot be expected to prevent deception at the hands of deepfakes, or to preserve the authority of video footage. Moreover, the success of such (...) technologies depends on institutional trust that is in short supply. Finally, outsourcing the discrimination between the real and the fake to automated, largely opaque systems runs the risk of undermining epistemic autonomy. (shrink)

Rachlin's thought-provoking analysis could be strengthened by greater openness to evolutionary interpretation and the use of the directed attention concept as a component of self-control.

This paper identifies and elucidates the underappreciated phenomenon of epistemic domination. Epistemic domination is the nonmutual capacity of one party to control the evidence available to another. Where this capacity is exercised, especially by parties that are ill-intentioned or ill-informed, the dominated party may have difficulty attaining epistemically valuable states. I begin with a discussion of epistemic domination and how it is possible. I then highlight three negative consequences that may result from epistemic domination.

The epistemic virtues and vices are typically defined in terms of effects or motivations related to the epistemic states of their possessors. However, philosophers have recently begun to consider _other-regarding_ epistemic virtues, traits oriented toward the epistemic flourishing of others. In a similar vein, this paper discusses _outward-facing_ epistemic vices, properties oriented toward the epistemic languishing of others. I argue for the existence of both reliabilist and responsibilist outward-facing vices, and illustrate how such vices negatively bear on the epistemic prospects (...) of others. I pay special attention to how outward-facing epistemic vices may manifest in online activities that promote the epistemic languishing of others by negatively influencing the online epistemic environment.

How did I raise my arm? The simple answer is that I raised it as a consequence of intending to raise it. A slightly more complicated response would mention the absence of any factors which would inhibit the execution of the intention- and a more complicated one still would specify the intention in terms of a goal (say, drinking a beer) which requires arm-raising as a means towards that end. Whatever the complications, the simple answer appears to be on the (...) right track. (shrink)

It is widely accepted that physicalism faces its most serious challenge when it comes to making room for the phenomenal character of psychological experience, its so-called what-it-is-like aspect. The challenge has surfaced repeatedly over the past two decades in a variety of forms. In a particularly striking one, Frank Jackson considers a situation in which Mary, a brilliant scientist who knows all the physical facts there are to know about psychological experience, has spent the whole of her life in a (...) black and white room. He asks, What will happen when Mary is released from her black and white room or is given a colour television monitor? Will she learn anything or not? It seems just obvious that she will learn something about the world and our visual experience of it. But then it is inescapable that her previous knowledge was incomplete. But she had all the physical information. (Jackson 1986: 130). (shrink)

The goal of this thesis is to model some of the cognitive structures and processes involve d in how people decide what to say in purposeful conversation. The main concern is to show how a speaker's knowledge of his/her hearer influences what s/he says. Utterances in such dialogues, where speakers can be presumed to be speaking for reasons, can best be viewed as the performance of "speech acts" (e.g., requesting). By modeling the process of deciding what to say as one (...) of problem-solving, we show that the same mechanisms used to plan non-linguistic actions are applicable to planning of speech acts. The methodology of this research employs a computer program that integrates beliefs, goals, problem-solving, and reasoning, with the use of language. The program does this by planning speech acts when it determines that to achieve its situational goals, it needs to influence someone else's behavior. The system is able to plan request speech actrions to influence its user's goals, and inform speech acts to influence his/her beliefs. In addition, it is shown that speech acts can be used to achieve subgoals of other such acts. For instance, in addition to requesting that the user perform some action, the system can also decide to supply him/her with information necessary to performing that action -- information that it believes s/he does not already have. Our model is extendable to the more general problem of planning multiparty speech acts -- ones where actions requested by the speaker involve acts to be performed by parties other than the hearer.

Our day-to-day experience of the world regularly brings us into contact with middlesized objects such as apples, dogs, and other human beings. These objects possess observable properties, properties that are available or accessible to the unaided senses, such as redness and roundness, as well as properties that are not so available, such as chemical ones. Both of these kinds of properties serve as valuable sources of information about our familiar middle-sized objects at least to the extent that they enable us (...) to understand the behaviours of those objects and their effects on each other and on us. I see the apple on the table before me, and in doing so I see its redness, its roundness, and so on. I do not see, but know that it has, a certain chemical constitution. The knowledge gained of the apple by means of both properties tells me something about the nature of that apple. In general, most, if not all, of the properties that objects in the observable world possess serve as the basis of our knowledge of such objects. But the subject-predicate form of much of our discourse and thought about objects suggests that substances are one kind of thing, properties another. We use subject terms such as names to identify objects, predicate terms to attribute properties to them. What, then, is it for an object to have a property? And what is the relation between an object and its properties? (shrink)

This paper argues that Kwasi Wiredu’s consensual democracy is an inadequate alternative to liberal democracy in contemporary Africa because it neglects the beliefs in supernatural realities underpinning governance and political decisions in traditional societies on the continent. The paper holds that as evident in their worldviews and activities, traditional Africans do not depersonalise entities or segregate physical realities from spiritual ones. Deploying historical and conceptual analyses, the paper contends that, essentially, the deficiency of Wiredu’s argument lies in his declining to (...) acknowledge the roles oaths and covenants play in the sustenance of Africa’s traditional governance systems. The paper thus holds that Wiredu’s discountenancing of the role of beliefs in supernatural realities in African societies generally may have resulted in this gap in his understanding of indigenous African political thought and practice.

AI is increasingly becoming based upon Internet-dependent systems to handle the massive amounts of data it requires to function effectively regardless of the availability of stable Internet connectivity in every affected community.

It must also include a thorough means whereby to ensure that affected communities gain the education and tools necessary to engage inclusively with new technological advances, whether they (...) be focused on machine learning algorithms or community infrastructure, as they will be increasingly dependent upon the automational capabilities of AI.

Philosophers who defend a person’s right, under certain circumstances, to end his own life or to have a physician end it for him typically appeal both to respect for patient autonomy and to considerations of beneficence. Neither autonomy alone nor beneficence alone can ground a persuasive case for euthanasia. I argue, however, that the standard argument for euthanasia is unsound. It is not possible to combine the principles of autonomy and beneficence in such a way as to justify euthanasia for (...) those who request it and are either incurably ill, in irremediable pain, or fearful of future incapacity, while excluding both involuntary euthanasia and assisted death for those who request it despite being neither incurably ill, in irremediable pain nor fearful of future incapacity.

It is widely accepted that knowledge of certain of one’s own mental states is authoritative in being epistemically more secure than knowledge of the mental states of others, and theories of self-knowledge have largely appealed to one or the other of two sources to explain this special epistemic status. The first, ‘detectivist’, position, appeals to an inner perception-like basis, whereas the second, ‘constitutivist’, one, appeals to the view that the special security awarded to certain self-knowledge is a conceptual matter. I (...) argue that there is a fundamental class of cases of authoritative self-knowledge, ones in which subjects are consciously thinking about their current, conscious intentional states, that is best accounted for in terms of a theory that is, broadly speaking, introspectionist and detectivist. The position developed has an intuitive plausibility that has inspired many who work in the Cartesian tradition, and the potential to yield a single treatment of the basis of authoritative self-knowledge for both intentional states and sensation states.

Genetic testing in the workplace is a technology both full of promise and fraught with ethical peril. Though not yet common, it is likely to become increasingly so.

What is knowledge of one's own current, consciously entertained intentional states a form of inner awareness? If so, what form? In this paper I explore the prospects for a quasi-observational account of a certain class of cases where subjects appear to have self-knowledge, namely, the so-called cogito-like cases. In section one I provide a rationale for the claim that we need an epistemology of self-knowledge, and specifically, an epistemology of the cogito-like cases. In section two I argue that contentful properties (...) in such cases have two features in common with observational properties of objects. In section three, I develop a quasi-observational account of self-knowledge for the cogito-like cases by considering various accounts of the nature of observational properties and by applying them to these cases. I conclude by addressing some important objections to the account. (shrink)

There is a consistent and simple interpretation of the quantum theory of isolated systems. The interpretation suffers no measurement problem and provides a quantum explanation of state reduction, which is usually postulated. Quantum entanglement plays an essential role in the construction of the interpretation.

Entanglement has been called the most important new feature of the quantum world. It is expressed in the quantum formalism by the joint measurement formula. We prove the formula for projection valued observables from a plausible assumption, which for spacelike separated measurements is an expression of relativistic causality. The state reduction formula is simply a way to express the joint measurement formula after one measurement has been made, and its result known.

This book argues that misinformation poses a multi-faceted threat to knowledge, while arguing that some forms of content moderation risk exacerbating these threats. It proposes alternative forms of content moderation that aim to address this complexity while enhancing human epistemic agency. The proliferation of fake news, false conspiracy theories, and other forms of misinformation on the internet and especially social media is widely recognized as a threat to individual knowledge and, consequently, to collective deliberation and democracy itself. This book argues (...) that misinformation presents a three-pronged threat to knowledge. While researchers often focus on the role of misinformation in causing false beliefs, this deceptive potential of misinformation exists alongside the potential to suppress trust and to distort the perception of evidence. Recognizing the multi-faceted nature of this threat is essential to the development of effective measures to mitigate the harms associated with misinformation. The book weaves together work in analytic epistemology with emerging empirical work in other disciplines to offer novel insights into the threats posed by misinformation. Additionally, it breaks new ground by systematically assessing different forms of content moderation from the perspective of epistemology. Misinformation, Content Moderation, and Epistemology will appeal to philosophers working in applied and social epistemology, as well as scholars and advanced students in disciplines such as communication studies, political science, and social psychology who are researching misinformation.

In this article, I outline a strategy for challenging J.L. Schellenberg’s hiddenness argument, and specifically the premise within the argument that asserts the existence of what Schellenberg calls nonresistant nonbelief. Drawing on some of the philosophical resources of skeptical theism, I show how this premise is based on a particular “noseeum assumption”—what I call Schellenberg’s Noseeum Assumption—that underwrites a particular “noseeum argument.” This assumption is that, regarding putative nonresistant nonbelievers, more likely than not we’d detect these nonbelievers’ resistance toward God (...) if there were any. I give reasons for thinking that it is not more reasonable to affirm than to refrain from affirming Schellenberg’s Noseeum Assumption, and so reason to think that the hiddenness argument is not a good argument for atheism. I also defend the strategy I outline against several objections. (shrink)

We outline a simple development of special and general relativity based on the physical meaning of the spacetime interval. The Lorentz transformation is not used.

Many recent discussions of self-consciousness and self-knowledge assume that there are only two kinds of accounts available to be taken on the relation between the so-called first-order (conscious) states and subjects' awareness or knowledge of them: a same-order, or reflexive view, on the one hand, or a higher-order one, on the other. I maintain that there is a third kind of view that is distinctively different from these two options. The view is important because it can accommodate and make intelligible (...) certain cases of authoritative self-knowledge that cannot easily be made intelligible, if at all, by these other two types of accounts. My aim in this paper is to defend this view against those who maintain that a same-order view is sufficient to account for authoritative self-knowledge. (shrink)

In general relativity, a spacetime and a gravitational field form an indivisible unit: no field, no spacetime. This is a lesson of Einstein's hole argument. We use a simple transformation in a Schwartzschild pacetime to illustrate this.

Nanotechnology research is beginning to see widespread coverage in the media and popular science literatures, but discussions of hopes and fears about nanotechnology have already become polarised into utopian and dystopian visions. More moderate discussions focus on the near-term applications of nanotechnologies, and on potential benefits and harms. However, in exploring the social and ethical implications of nanotechnology, important lessons should be learned from experiences in other fields. In particular, studies of the ethical, legal, and social issues of genetics research (...) have successfully mapped out many of the issues that arise when new technologies are deployed. It is our contention that, for the most part, the ethical and social issues arising in nanomedicine are not altogether new, and thus do not require novel ethical principles or frameworks, nor a massive investment in ‘NELSI’ research. Instead, what is needed is support for the development of a culture of ethics amongst scientists and clinicians, basic scientific and medical knowledge for bioethicists, and a social competency for citizens to participate actively in debates about the implications of new technologies in general.

The precarious rights of senior citizens, especially those who are highly educated and who are expected to counsel and guide the younger generations, has stimulated the creation internationally of advocacy associations and opinion leader groups. The strength of these groups, however, varies from country to country. In some countries, they are supported and are the focus of intense interest; in others, they are practically ignored. For this is reason we believe that the creation of a network of all these associations (...) is essential. The proposed network would act as a support for the already-existing policies of the United Nations’ High Commission for Human Rights, of independent experts, and of the Global Alliance for the Rights of Older People. All three have long ago recommended the creation of a recognized instrument for uniting presently scattered efforts. The proposed network, therefore, will seek to promote the international exchange of relevant expertise, and it will reinforce the commitments and actions that single countries are currently taking to meet these objectives. For example, informative public events can be organised to promote particular support initiatives and to provide an opportunity for new members of the network to be presented. The network will promote health for senior citizens, disease prevention, senior mobility, safe free time for seniors, alimentary education, protection against new risks and dangers, as well as equity in the services necessary for seniors to adopt new information and communication technologies. In the case of retired academic members, the network will promote equality with respect to continuing use of digital technologies (particularly email), continuing access to research libraries, and the guaranteed ability for seniors to fund their own research programs and to deliver free seminars.

Do laypeople and philosophers differ in their attributions of knowledge? Starmans and Friedman maintain that laypeople differ from philosophers in taking ‘authentic evidence’ Gettier cases to be cases of knowledge. Their reply helpfully clarifies the distinction between ‘authentic evidence’ and ‘apparent evidence’. Using their sharpened presentation of this distinction, we contend that the argument of our original paper still stands.

Significant associations have been found between specific human leukocyte antigen (HLA) alleles and organ transplant rejection, autoimmune disease development, and the response to infection. Traditional searches for disease associations have conventionally measured risk associated with the presence of individual HLA alleles. However, given the high level of HLA polymorphism, the pattern of amino acid variability, and the fact that most of the HLA variation occurs at functionally important sites, it may be that a combination of variable amino acid sites shared (...) by several alleles (shared epitopes) are better descriptors of the actual causative genetic variants. Here we describe a novel approach to genetic association analysis in which genes/proteins are broken down into smaller sequence features and then variant types defined for each feature, allowing for independent analysis of disease association with each sequence feature variant type. We have used this approach to analyze a cohort of systemic sclerosis patients and show that a sequence feature composed of specific amino acid residues in peptide binding pockets 4 and 7 of HLA-DRB1 explains much of the molecular determinant of risk for systemic sclerosis.

Each annual Ontology Summit initiative makes a statement appropriate to each Summit’s theme as part of our general advocacy designed to bring ontology science and engineering into the mainstream. The theme this year is "Towards an Open Ontology Repository". This communiqué represents the joint position of those who were engaged in the year's summit discourse on an Open Ontology Repository (OOR) and of those who endorse below. In this discussion, we have agreed that an "ontology repository is a facility where (...) ontologies and related information artifacts can be stored, retrieved and managed." -/- We believe in the promise of semantic technologies based on logic, databases and the Semantic Web, a Web of exposed data and of interpretations of that data (i.e., of semantics), using common standards. Such technologies enable distinguishable, computable, reusable, and sharable meaning of Web and other artifacts, including data, documents, and services. We also believe that making that vision a reality requires additional supporting resources and these resources should be open, extensible, and provide common services over the ontologies. (shrink)

Worldwide populations are aging with economic development as a result of public health initiatives and advances in therapeutic discoveries. Since 1850, life expectancy has advanced by 1 year for every four. Accompanying this change is the rapid development of anti‐aging science. There are three schools of thought in the field of aging science. One perspective is the life course approach, which considers that aging is a good and natural process to be embraced as a necessary and positive aspect of life, (...) where the aim is to improve the quality of existing lifespan and “compress” morbidity. Another view is that aging is undesirable, and that rejuvenation and indeed immortality are possible since the biological basis of aging is understood, and therefore, strategies are possible for engineering negligible senescence. Finally, a hybrid approach is that life span can be extended by anti‐aging medicines but with uncertain effects on health. While these advances offer much promise, the ethical perspectives are seldom discussed in cross‐disciplinary settings. This article discusses some of the key ethical issues arising from recent advances in biogerontology. (shrink)

Margaret Macdonald was at the institutional heart of analytic philosophy in Britain in the mid-twentieth century. Yet, her views on the nature of philosophical theories diverge quite considerably from those of many of her contemporaries. In this paper, I focus on her 1953 article ‘Linguistic Philosophy and Perception’, a provocative paper in which Macdonald argues that the value of philosophical theories is more akin to that of poetry or art than science or mathematics. I do so for two (...) reasons. First, because it reveals just how far Macdonald’s meta- philosophical views diverged from those of many of her contemporaries. Second, because the discussion in LPP pre-empts recent literature on the nature of philosophical inquiry and the efficacy of philosophical arguments. Indeed, Macdonald’s paper is just as likely to provoke discussion today as it was in the 1950s. (shrink)

Margaret MacDonald (1907–56) was a central figure in the history of early analytic philosophy in Britain due to both her editorial work as well as her own writings. While her later work on aesthetics and political philosophy has recently received attention, her early writings in the 1930s present a coherent and, for its time, strikingly original blend of common-sense and scientific philosophy. In these papers, MacDonald tackles the central problems of philosophy of her day: verification, the problem of (...) induction, and the relationship between philosophical and scientific method. MacDonald’s philosophy of science starts from the principle that we should carefully analyse the elements of scientific practice (particularly its temporal features) and the ways that scientists describe that practice. That is, she applies the techniques of ordinary language philosophy to actual scientific language. MacDonald shows how ‘scientific common-sense’ is inconsistent with both of the dominant schools of philosophy of her day. Bringing MacDonald back into the story of analytic philosophy corrects the impression that in early analytic philosophy, there are fundamental dichotomies between the style of Moore and Wittgenstein, on the one hand, and the Vienna Circle on the other.
