Biological ontologies are used to organize, curate, and interpret the vast quantities of data arising from biological experiments. While this works well when using a single ontology, integrating multiple ontologies can be problematic, as they are developed independently, which can lead to incompatibilities. The Open Biological and Biomedical Ontologies Foundry was created to address this by facilitating the development, harmonization, application, and sharing of ontologies, guided by a set of overarching principles. One challenge in reaching these goals was that the (...) OBO principles were not originally encoded in a precise fashion, and interpretation was subjective. Here we show how we have addressed this by formally encoding the OBO principles as operational rules and implementing a suite of automated validation checks and a dashboard for objectively evaluating each ontology’s compliance with each principle. This entailed a substantial effort to curate metadata across all ontologies and to coordinate with individual stakeholders. We have applied these checks across the full OBO suite of ontologies, revealing areas where individual ontologies require changes to conform to our principles. Our work demonstrates how a sizable federated community can be organized and evaluated on objective criteria that help improve overall quality and interoperability, which is vital for the sustenance of the OBO project and towards the overall goals of making data FAIR.

In Brazil, the social demand for veterinary expertise is growing. However, there is still a shortage of professionals trained in this area to apply specific knowledge to each case. Studies and research into forensic veterinary medicine are necessary for veterinary experts to assist in investigations and legal proceedings. Veterinary medicine has subjects on its curriculum that cover the knowledge needed to apply in the fields of animal health, public health and the environment. The interaction between human and veterinary medicine, as (...) well as other areas of health, is of great importance in the prevention and control of various diseases, both in animals and humans. Some cases of infectious bovine abortion have a major impact not only on cattle farming and animal health, but also on public and environmental health. The concept of "One Health" integrates human medicine and health professionals. In this context, knowledge of infectious abortive diseases that affect animal, human and environmental health is fundamental. Cattle are affected by specific infectious abortive diseases, caused by pathogens with different forms of presentation and transmission mechanisms. These include brucellosis, leptospirosis and listeriosis, which are potentially zoonotic diseases. Controlling these diseases can contribute to effective public health actions and reduce global health risks. In order to establish the diagnosis of these diseases, it is essential to properly collect specimens from live or dead animals under biosafety and biosecurity conditions, following the chain of custody for each case. These procedures allow for greater success in diagnosing the suspected agent and facilitate the investigation of other causes. Animal health standards for the prophylaxis and control of these diseases are established by specific legislation, including those of the Ministry of Agriculture, Livestock and Supply (MALS). This literature review was based on current knowledge on the Pubmed platform, Google Scholar, articles and textbooks. The aim of this article is to identify, understand and discuss the main infectious abortive diseases of cattle in the legal and forensic context, which have an impact on cattle farming, animal health, food safety, public and environmental health. -/- Referências bibliográficas Abdullah, N.

Philosophers and social scientists largely agree that fake news is not just necessarily untruthful, but necessarily insincere: it’s produced either with the intention to deceive or an indifference toward its truth. Against this, I argue insincerity is neither a necessary nor obviously typical feature of fake news. The main argument proceeds in two stages. The first, methodological step develops classification criteria for identifying instances of fake news. By attending to expressed theoretical and practical interests, I observe how our classification practices (...) turn on worries about fake news’s unique political-epistemic risks. From this, I argue (i) theories of fake news should capture independent mechanisms that realise these risks and (ii) the manifestation of them suffices for classifying a news story as fake news. The second step applies the classification criteria to bad science journalism. I argue the systematic epistemic faults in bad science journalism manifest the same political-epistemic risks we see in fake news, which suffices to justify classifying it as fake news. But since such faults aren’t plausibly attributed to its propagators being insincere, insincerity doesn’t function independently as a mechanism for realising fake news’s political-epistemic risks. Thus, I conclude, we should exclude insincerity from our accounts of the phenomenon. (shrink)

In this paper, I discuss whether different interpretations of the ‘aim’ of belief—both the teleological and normative interpretations—have the resources to explain certain descriptive and normative features of suspended belief (suspension). I argue that, despite the recent efforts of theorists to extend these theories to account for suspension, they ultimately fail. The implication is that we must either develop alternative theories of belief that can account for suspension, or we must abandon the assumption that these theories ought to be able (...) to account for suspension. To close, I briefly consider some of the reasons we have in favour of pursing each of these options, and I suggest that it is worth exploring the possibility that suspension is best understood as its own attitude, independently of theories of belief’s ‘aim’.

In this paper, I defend teleological theories of belief against the exclusivity objection. I argue that despite the exclusive influence of truth in doxastic deliberation, multiple epistemic aims interact when we consider what to believe. This is apparent when we focus on the processes involved in specific instances (or concrete cases) of doxastic deliberation, such that the propositions under consideration are specified. First, I out- line a general schema for weighing aims. Second, I discuss recent attempts to defend the teleological (...) position in relation to this schema. And third, I develop and defend my proposal that multiple epistemic aims interact in doxastic deliberation—a possibility which, as of yet, has received no serious attention in the literature.

Prior research has demonstrated that antisocial behavior, substance-use disorders, and personality dimensions of aggression and impulsivity are indicators of a highly heritable underlying dimension of risk, labeled externalizing. Other work has shown that individual trait constructs within this psychopathology spectrum are associated with reduced self-monitoring, as reflected by amplitude of the error-related negativity (ERN) brain response. In this study of undergraduate subjects, reduced ERN amplitude was associated with higher scores on a self-report measure of the broad externalizing construct that links (...) these various indicators. In addition, the ERN was associated with a response-locked increase in anterior theta (4–7 Hz) oscillation; like the ERN, this theta response to errors was reduced among high-externalizing individuals. These findings suggest that neurobiologically based deficits in endogenous action monitoring may underlie generalized risk for an array of impulse-control problems. (shrink)

The United States Fish and Wildlife Service in Alaska, USA, conducted a species status assessment for a petition to list the Alexander Archipelago wolf (Canis lupus ligoni) under the Endangered Species Act in 2020-2022. This federal undertaking could not be adequately prepared without including the knowledge of Indigenous People who have a deep cultural connection with the subspecies. Our objective is to communicate the authoritative expertise and voice of the Indigenous People who partnered on the project by demonstrating how their (...) knowledge contributed to the species status assessment. The Indigenous knowledge applied in the assessment is the cultural and intellectual property of those who have shared it. We employed rapid appraisal research to expeditiously develop a preliminary and qualitative understanding of Indigenous People's cultural and ecological knowledge of Alexander Archipelago wolves. We used semi-directed interviewing and inductive coding from grounded theory for text analysis. Indigenous knowledge contributed to the agency's understanding of the Alexander Archipelago wolf in Southeast Alaska and helped the agency with their classification decision. Indigenous research partners explained the rich cultural significance and position of wolves in Tlingit society and described human–wolf relationships and ecological interactions. The agency used a single-species assessment approach based in species ecology and conservation biology, whereas the Indigenous wolf experts applied a multi-species, community ecology approach based in a sociocultural context of balance and respect. The Indigenous wolf experts successfully addressed knowledge gaps identified by the agency. The partners were challenged by a short regulatory timeframe that did not allow for comprehensive study of Indigenous knowledge and constrained review and feedback by Indigenous experts. The United States Fish and Wildlife Service learned that its assessment framework was not designed to account for an Indigenous worldview. To level the playing field, the agency and Indigenous experts should discuss how to co-develop an assessment framework that equitably applies both perspectives. (shrink)

Atualmente, biotecnologias são empregadas na forma de protocolos a fim de sincronizar o crescimento folicular e a ovulação, bem como permitir que vacas atuem como receptoras de embriões visando melhorar o potencial genético do rebanho. O objetivo desse estudo foi avaliar o efeito da utilização de implantes intravaginais de progesterona de 1º, 2º e 3º uso no protocolo de transferência de embriões em tempo fixo (TETF) sobre a taxa de prenhez em receptoras girolandas. O experimento ocorreu em uma fazenda localizada (...) no município de São Sebastião do Maranhão (MG). Foram utilizadas 74 vacas submetidas aos seguintes protocolos: No dia 0 (D0) administrou-se 2 ml de 17β-Estradiol e progesterona e foi colocado o implante intravaginal de progesterona. Estes implantes foram colocados de forma aleatória, sendo de 1° uso (grupo 1; n=15), 2° (grupo 2; n=24) ou 3° (grupo 3; n=35).No D8, os implantes foram retirados e administrou-se 2 ml PGF2α; 1,5 ml de eCG e 1 ml de 17β-Estradiol e progesterona. A inovulação dos embriões in vitroo correu no D (16) para todas as vacas que apresentaram um corpo lúteo. As variáveis qualitativas (prenhe ou não prenhe) foram comparadas em tabelas de contingência e analisadas pelo teste de qui-quadrado a 5% de probabilidade. Neste estudo não houve diferença estatística entre os grupos protocolados em relação ao aproveitamento como receptoras: 1º uso (53,3%), 2º (79,2%) e 3º (68,65). Ademais, observou-se uma taxa de prenhez entre os grupos de 37,5% para o 1º uso, 42,1% para o 2º e 33,3% para o 3º (P>0,05). Dentre as vantagens ao reaproveitamento dos implantes multiusos destaca-se a redução dos custos dos protocolos hormonais, já que a progesterona é o hormônio mais oneroso, desta forma, a maximização do uso reduz o valor final do protocolo sem prejuízos a taxa de prenhez.

The two purposes of this essay. The general philosophical problem with most versions of social libertarianism and how this essay will proceed. The specific problem with liberty explained by a thought-experiment. The positive and abstract theory of interpersonal liberty-in-itself as ‘the absence of interpersonal initiated constraints on want-satisfaction’, for short ‘no initiated impositions’. The individualistic liberty-maximisation theory solves the problems of clashes, defences, and rectifications without entailing interpersonal utility comparisons or libertarian consequentialism. The practical implications of instantiating liberty: three rules (...) of liberty-in-practice, 1) initial ultimate control of one’s body, 2) initial ultimate control of one’s used resources, 3) consensual interpersonal interactions and resource transfers. These rules are economically efficient and maximise general want-satisfaction. Private property and legal remedies are additional practical institutional aspects, but to which ‘initiated impositions’ then apply prima facie. Libertarian law is often mistaken for complete libertarianism. Moral explanations are a separate issue. The three main moral theories imply libertarianism, but it can be morally posited independently of them. Critical rationalism and its application. No empirical or argumentative support for theories. An important ambiguity with ‘justification’. How the epistemology applies to the theory of liberty and its application but remains separable in principle. Conclusion: there are further published explanations but this should be enough to generate useful criticism. Appendix replying to some typical comments. (shrink)

Recent thinking within philosophy of mind about the ways cognition can extend has yet to be integrated with philosophical theories of emotion, which give cognition a central role. We carve out new ground at the intersection of these areas and, in doing so, defend what we call the extended emotion thesis: the claim that some emotions can extend beyond skin and skull to parts of the external world.

In a reflective and richly entertaining piece from 1979, Doug Hofstadter playfully imagined a conversation between ‘Achilles’ and an anthill (the eponymous ‘Aunt Hillary’), in which he famously explored many ideas and themes related to cognition and consciousness. For Hofstadter, the anthill is able to carry on a conversation because the ants that compose it play roughly the same role that neurons play in human languaging; unfortunately, Hofstadter’s work is notably short on detail suggesting how this magic might be achieved1. (...) Conversely in this paper - finally reifying Hofstadter’s imagination - we demonstrate how populations of simple ant-like creatures can be organised to solve complex problems; problems that involve the use of forward planning and strategy. Specifically we will demonstrate that populations of such creatures can be configured to play a strategically strong - though tactically weak - game of HeX (a complex strategic game).We subsequently demonstrate how tactical play can be improved by introducing a form of forward planning instantiated via multiple populations of agents; a technique that can be compared to the dynamics of interacting populations of social insects via the concept of meta-population. In this way although, pace Hofstadter, we do not establish that a meta-population of ants could actually hold a conversation with Achilles, we do successfully introduce Aunt Hillary to the complex, seductive charms of HeX.

Visual imagery is a form of sensory imagination, involving subjective experiences typically described as similar to perception, but which occur in the absence of corresponding external stimuli. We used the Activation Likelihood Estimation algorithm (ALE) to identify regions consistently activated by visual imagery across 40 neuroimaging studies, the first such meta-analysis. We also employed a recently developed multi-modal parcellation of the human brain to attribute stereotactic co-ordinates to one of 180 anatomical regions, the first time this approach has been combined (...) with the ALE algorithm. We identified a total 634 foci, based on measurements from 464 participants. Our overall comparison identified activation in the superior parietal lobule, particularly in the left hemisphere, consistent with the proposed ‘top-down’ role for this brain region in imagery. Inferior premotor areas and the inferior frontal sulcus were reliably activated, a finding consistent with the prominent semantic demands made by many visual imagery tasks. We observed bilateral activation in several areas associated with the integration of eye movements and visual information, including the supplementary and cingulate eye fields (SCEFs) and the frontal eye fields (FEFs), suggesting that enactive processes are important in visual imagery. V1 was typically activated during visual imagery, even when participants have their eyes closed, consistent with influential depictive theories of visual imagery. Temporal lobe activation was restricted to area PH and regions of the fusiform gyrus, adjacent to the fusiform face complex (FFC). These results provide a secure foundation for future work to characterise in greater detail the functional contributions of specific areas to visual imagery. (shrink)

While openmindedness is often cited as a paradigmatic example of an intellectual virtue, the connection between openmindedness and truth is tenuous. Several strategies for reconciling this tension are considered, and each is shown to fail; it is thus claimed that openmindedness, when intellectually virtuous, bears no interesting essential connection to truth. In the final section, the implication of this result is assessed in the wider context of debates about epistemic value.

Duncan Pritchard (2008, 2009, 2010, forthcoming) has argued for an elegant solution to what have been called the value problems for knowledge at the forefront of recent literature on epistemic value. As Pritchard sees it, these problems dissolve once it is recognized that that it is understanding-why, not knowledge, that bears the distinctive epistemic value often (mistakenly) attributed to knowledge. A key element of Pritchard’s revisionist argument is the claim that understanding-why always involves what he calls strong cognitive achievement—viz., cognitive (...) achievement that consists always in either (i) the overcoming of a significant obstacle or (ii) the exercise of a significant level of cognitive ability. After outlining Pritchard’s argument, we show (contra Pritchard) that understanding-why does not essentially involve strong cognitive achievement. Interestingly, in the cases in which understanding-why is distinctively valuable, it is (we argue) only because there is sufficiently rich objectual understanding in the background. If that’s right, then a plausible revisionist solution to the value problems must be sensitive to different kinds of understanding and what makes them valuable, respectively. (shrink)

Collingwood’s aim in The Principles of Art is “to answer the question: What is art?” (p. 1) The answer Collingwood offers to that question, that art is the expression of emotion, has become notorious for its implausibility. I consider one objection against this theory, namely that it is unclear what is rendered art by this definition: for it sometimes appears to define art too broadly, containing all utterances and gestures; but at other times to define art too narrowly, excluding much (...) of what we intuitively consider art. -/- I argue that this objection is mistaken, because it is founded upon a misunderstanding of the sort of project in which Collingwood is engaged. I propose a new reading, via his philosophical methodology, under which ‘art’ is differentially rather than binarily realisable. According to this new reading, art is something found in every human experience or activity, but to a greater or lesser extent. I close by suggesting one reason why Collingwood’s project under this reading is more philosophically interesting than it is under the standard reading, namely that it can give a better account of borderline cases of art.

This paper focuses on invasive therapeutic procedures, defined as procedures requiring the introduction of hands, instruments, or devices into the body via incisions or punctures of the skin or mucous membranes performed with the intent of changing the natural history of a human disease or condition for the better. Ethical and methodological concerns have been expressed about studies designed to evaluate the effects of invasive therapeutic procedures. Can such studies meet the same standards demanded of those, for example, evaluating pharmaceutical (...) agents? This paper describes a research project aimed at examining the interplay and sometimes apparent conflict between ethical standards for human research and standards for methodological rigor in trials of invasive procedures. The paper discusses how the authors plan to develop a set of consensus standards that, if met, would result in substantial and much-needed improvements in the methodological and ethical quality of such trials.

On the face of it, Maurice Merleau-Ponty’s views bear a strong resemblance to contemporary disjunctivist theories of perception, especially John McDowell’s epistemological disjunctivism. Like McDowell (and other disjunctivists), Merleau-Ponty seems to be a direct realist about perception and holds that veridical and illusory perceptions are distinct. This paper furthers this comparison. Furthermore, it is argued that elements of Merleau-Ponty’s thought provide a stronger case for McDowell’s kind of epistemological view than McDowell himself provides. Merleau-Ponty’s early thought can be used to (...) develop a unique version of epistemological disjunctivism that is worth consideration alongside contemporary views on perceptual knowledge.

Recent work in the philosophy of mind and cognitive science (e.g., Clark and Chalmers 1998; Clark 2010a; Clark 2010b; Palermos 2014) can help to explain why certain kinds of assertions—made on the basis of information stored in our gadgets rather than in biological memory—are properly criticisable in light of misleading implicatures, while others are not.

Epistemology is often a problem for libertarianism. Many libertarian texts assume that they need to do more than explain and defend the libertarian conjecture. Instead, they try to offer epistemological support for it (whether empirically or morally); which falsificationism and, more broadly, critical rationalism explains is not possible. Moreover, they often mistake this attempt at support for an explanation of libertarianism (which ought to include an abstract theory of liberty and how it relates to liberty in practice). Therefore, when a (...) criticism of falsificationism appears on a libertarian website it seems useful to reply to it (even though no discussion of libertarianism itself is involved). (shrink)

The editors of the Journal of Applied Philosophy allowed Alan Haworth to reply to my short review of his Anti-Libertarianism. The editors would not allow me to respond to Haworth. Thanks to the openness of internet publication and the Libertarian Alliance website, this can now be rectified and Haworth's reply can no longer escape a public critical response.

Libertarians are mistaken to seek foundations, to take sides over moral approaches, and to have no proper theory of liberty.

Vallentyne 2010 and Zwolinski 2008 are internet encyclopaedia articles on “libertarianism” which include various serious faults. Vallentyne 2010 has the following ones. It does not properly explain mainstream libertarianism or consider criticisms of it. Instead, it mainly discusses self-ownership and natural-resource egalitarianism. Every aspect of the alleged “strict sense” of “libertarianism” is dubi ous, at best. So- called “left - libertarianism” is not made sense of as any kind of liberty-based libertarianism. Problems arise because self-ownership is assumed to be libertarian (...) without an explicit theory of libertarian liberty. The replies to “five impor tant objections to full self- ownership” are confused and mistaken; both as regards philosophical analysis and as regards empirical assumptions. The long discussion about various ways to “Appropriate Natural Resources” is rendered muddled and barren by the lack of a clear libertarian theory of liberty, the mere presumption of some form of egalitarianism, and the inclusion of various non-libertarian criteria. The remaining sections are largely uninformed by any relevant libertarian literature. It reaches a justificationist conclusion that cites mistaken welfare concerns and ignores the productivity of free markets. Zwolinski 2008 shares some errors with Vallentyne 2010, but also includes the following ones. It is even less clear about what libertarian liberty is. It fails to understand that libertarianism (private-property anarchy and, possibly, minarchy) is a subset of classical liberalism. It asserts that libertarianism is about “the proper role of government.” It assumes (illogical) justificationist/foundationalist epistemology and does not mention critical-rationalist libertarianism. It eventually faults justificationism and unwittingly assumes something approaching critical rationalism. Finally, it embraces John Rawls’s “overlapping consensus” as a “justification” (i.e., defence) of libertarianism oblivious to the similar position in Lester 1996 and 2000. (shrink)

This is a response to Macleod 2012's argument that the history of unjust property acquisitions requires rich libertarians to give away everything in excess of equality. At first, problematic questions are raised. How much property is usually inherited or illegitimate? Why should legitimate inheritance be affected? What of the burden of proof and court cases? A counterfactual problem is addressed. Three important cases are considered: great earned wealth; American slavery; land usurpation. All are argued to be problematic for Macleod 2012's (...) thesis. Various problems are explained concerning using the Nozickian argument to decide the alleged excess that rich libertarians own. The essay's main error is the presupposition that free markets do not help the worst-off. The majority of unjust holdings today are not the result of historical injustices but arise through continuing transfers enabled by taxation and state-regulation. More study of libertarian contributions to the social sciences and philosophy would appear to be desirable "personal behavior" among socialists. (shrink)

Libertarianism—and classical liberalism generally—entails (or presupposes) a specific, but implicit, conception of liberty. Imagine two lists of property-rights: one list is all those that currently appear to be libertarian (self-ownership, property acquired by use of natural resources, property acquired by consensual exchange, etc.); the other list is all those that currently appear not to be libertarian (aggressively imposed slavery, property acquired by theft or fraud, property acquired by coerced transfers due to welfare claims, etc.). What determines into which list a (...) property-right is to be assigned? If libertarianism is really about liberty, then the determining factor must be whether the property-right somehow fits what liberty is in a more abstract sense than property. It greatly clarifies matters to have an explicit theory of this entailed conception of abstract liberty and how it relates to its practical application and to morality. (shrink)

David Friedman posed a number of libertarian philosophical problems (Friedman 1989). This essay criticizes Walter Block’s Rothbardian responses (Block 2011) and compares them with J C Lester’s critical-rationalist, libertarian-theory responses (Lester [2000] 2012). The main issues are as follows. 1. Critical rationalism and how it applies to libertarianism. 2.1. How libertarianism is not inherently about law and is inherently about morals. 2.2. How liberty relates to property and can be maximized: carbon dioxide and radio waves. 2.3. Applying the theory to (...) flashlights. 2.4. Applying the theory to the probability of imposed risks. 2.5. “Homesteading” or initial acquisition. 2.6 What is “essential” for a “true libertarian.” 2.7. Crime and punishment. 2.8. Extent of punishment. 2.9. The libertarian response to a madman with a gun. 2.10. How contradictions in rights are possible. 2.11. The draft. 3.1. Utilitarian libertarianism and “nose counting”. 3.2. How interpersonal comparisons of utility are possible and utility monsters are not a threat. 3.3. Why it is not utilitarian in practice to kill an innocent prisoner to prevent a riot. 3.4. Why David Friedman should not be forced to give up one of his eyes. 3.5. How utilitarians can be libertarians. Conclusion: a proper theory of liberty combined with critical rationalism offers superior solutions to Friedman’s problems. Appendix: replies to two commentators. (shrink)

This is an attempt to clarify the nature of extreme, or complete, “wokeness” in its modern sense. The central thesis is that it is an inverted form of fascism, and thereby even worse than some of its critics assume. In fact, it is far worse than ordinary fascism whether or not it is correct to see it as an inverted form. As this is a thesis, it is not a definition. Therefore, this thesis could certainly be mistaken. But if it (...) is, then sound criticisms of the explanation would be needed to refute it. (shrink)

This paper has two central aims. First, we motivate a puzzle. The puzzle features four independently plausible but jointly inconsistent claims. One of the four claims is the sufficiency leg of the knowledge norm of assertion (KNA-S), according to which one is properly epistemically positioned to assert that p if one knows that p. Second, we propose that rejecting (KNA-S) is the best way out of the puzzle. Our argument to this end appeals to the epistemic value of intellectual humility (...) in social-epistemic practice.

It has been hypothesized that our believing that, or its seeming to us as though, the world is in some way dynamical partially explains (and perhaps rationalizes) future-bias. Recent work has, in turn, found a correlation between future-bias and near-bias, suggesting that there is a common explanation for both. Call the claim that what partially explains our being both future- and near-biased is our believing/it seeming to us as though the world is dynamical, the dynamical explanation. We empirically test two (...) versions of the dynamical explanation. The first is the moving ego explanation—according to which it is our belief that the ego moves, or our phenomenology as of the ego moving, that jointly (partially) explains future- and near-bias. The second is the moving time explanation—according to which it is our belief that time robustly passes, or our phenomenology as of robust passage, which jointly (partially) explain future- and near-bias. We found no evidence in favour of either explanation. (shrink)

Epistemic relativists often appeal to an epistemic incommensurability thesis. One notable example is the position advanced by Wittgenstein in On certainty (1969). However, Ian Hacking’s radical denial of the possibility of objective epistemic reasons for belief poses, we suggest, an even more forceful challenge to mainstream meta-epistemology. Our central objective will be to develop a novel strategy for defusing Hacking’s line of argument. Specifically, we show that the epistemic incommensurability thesis can be resisted even if we grant the very insights (...) that lead Hacking to claim that epistemic reasons are always relative to a style of reasoning. Surprisingly, the key to defusing the argument is to be found in recent mainstream work on the epistemic state of objectual understanding. (shrink)

“Critical-Rationalist Libertarianism” (CRL) was replied to in “Libertarianism Without Argument” (the reply). Various points in that text are here given responses. Both critical rationalism and how it applies to libertarianism are elucidated and elaborated. This response will proceed by quoting the reply where relevant (virtually all of it) and then responding immediately after the quotations, following the order of the reply’s very brief “critique” (605 words).

Linda Zagzebski’s book on epistemic authority is an impressive and stimulating treatment of an important topic. 1 I admire the way she manages to combine imagination, originality and argumentative control. Her work has the further considerable merit of bringing analytic thinking and abstract theory to bear upon areas of concrete human concern, such as the attitudes one should have towards moral and religious authority. The book is stimulating in a way good philosophy should be -- provoking both disagreement and emulation. (...) I agree with much of what she says, and have been instructed by it, but it will be of more interest and relevance here if I concentrate upon areas of disagreement. Perhaps they are better seen as areas, at least some of them, where her emphases suggest a position that seems to me untenable, but that she may not really intend. In that event, I will be happy to have provoked a clarification or the dispelling of my misunderstanding. My focus will be upon problems in her account of communal authority and autonomy, especially with respect to religious and political authority. Here my worry is that she places too much trust in trust and not enough in what I call selective mistrust. (shrink)

Background If trials of therapeutic interventions are to serve society's interests, they must be of high methodological quality and must satisfy moral commitments to human subjects. The authors set out to develop a clinical - trials compendium in which standards for the ethical treatment of human subjects are integrated with standards for research methods. Methods The authors rank-ordered the world's nations and chose the 31 with >700 active trials as of 24 July 2008. Governmental and other authoritative entities of the (...) 31 countries were searched, and 1004 English-language documents containing ethical and/or methodological standards for clinical trials were identified. The authors extracted standards from 144 of those: 50 designated as ‘core’, 39 addressing trials of invasive procedures and a 5% sample of the remainder. As the integrating framework for the standards we developed a coherent taxonomy encompassing all elements of a trial's stages. Findings Review of the 144 documents yielded nearly 15 000 discrete standards. After duplicates were removed, 5903 substantive standards remained, distributed in the taxonomy as follows: initiation, 1401 standards, 8 divisions; design, 1869 standards, 16 divisions; conduct, 1473 standards, 8 divisions; analysing and reporting results, 997 standards, four divisions; and post-trial standards, 168 standards, 5 divisions. Conclusions The overwhelming number of source documents and standards uncovered in this study was not anticipated beforehand and confirms the extraordinary complexity of the clinical trials enterprise. This taxonomy of multinational ethical and methodological standards may help trialists and overseers improve the quality of clinical trials, particularly given the globalisation of clinical research.

Maurice Merleau-Ponty is often interpreted as claiming that opportunities for action are directly present in perceptual experience. However, he does not provide much evidence for how or why this would occur, and one can doubt that this is an appropriate interpretation of his phenomenological descriptions. In particular, it could be argued the Merleau-Pontyian descriptions mistakenly attribute pre-perceptual or post-perceptual elements such as allocation of attention or judgment to the perceptual experience itself. This paper argues for the Merleau-Pontyian idea that opportunities (...) for action are present in perceptual experience. It further argues that the phenomenological descriptions can be supported and explained via reference to contemporary research on motor imagery. In particular, it will be argued that non-conscious, covert motor imagery is used to prepare for and regulate skilled actions, and that it is plausible that this imagery combines with perception (likely vision) to create a single experience of the environment as enabling action. The paper will also show that contemporary views on motor imagery are broadly compatible with Merleau-Ponty’s aims. (shrink)

1. First there is an outline of the libertarian approach taken here. 2. On the assumption of personhood, it is explained how there need be no overall inflicted harm and no proactive killing with abortion and infanticide. This starts with an attached-adult analogy and transitions to dealing directly with the issues. Various well-known criticisms are answered throughout. 3. There is then a more-abstract explanation of how it is paradoxical to assume a duty to do more than avoid inflicting overall harm (...) and, instead, positively benefit. A putative counterexample is explained away. 4. A positive theory of intellectual personhood is defended in principle, but not made precise, which is sufficient to be practical. The greater moral value of intellectual-personhood is defended. An important putative reductio of the potential-personhood argument is refuted. 5. Several further criticisms that apply to both types of defences are answered. 6. Conclusion. (shrink)

Peter Singer’s famous and influential article is criticised in three main ways that can be considered libertarian, although many non-libertarians could also accept them: 1) the relevant moral principle is more plausibly about upholding an implicit contract rather than globalising a moral intuition that had local evolutionary origins; 2) its principle of the immorality of not stopping bad things is paradoxical, as it overlooks the converse aspect that would be the positive morality of not starting bad things and also thereby (...) conceptually eliminates innocence; and 3) free markets—especially international free trade—have been cogently explained to be the real solution to the global “major evils” of “poverty” and “pollution”, while “overpopulation” does not exist in free-market frameworks; hence charity is a relatively minor alleviant to the problem of insufficiently free markets. There are also various subsidiary arguments throughout. (shrink)

Until quite recently, it has appeared that eleutheric-conjectural libertarianism (ECL) could not avoid some degree of, very broad, interpersonal utility comparisons (IUCs). And this has been objected to by some of its libertarian critics, notably economists and propertarians. Indeed, this aspect does make the theory less compatible with economics than the rest of the theory and it is thereby a significant problem. This is because one of the main problems that ECL is intended to solve is how an abstract theory (...) of liberty can be compatible with the pro-free-market conclusions of many economists. Being more compatible with economics should make ECL theory more comprehensive, comprehensible, and cogent. (shrink)

Purpose Prescription stimulant use as “cognitive enhancers” has been described among undergraduate college students. However, the use of prescription stimulants among future health care professionals is not well characterized. This study was designed to determine the prevalence of prescription stimulant misuse among students at an academic health sciences center. -/- Method Electronic surveys were e-mailed to 621 medical, pharmacy, and respiratory therapy students at East Tennessee State University for four consecutive weeks in fall 2011. Completing the survey was voluntary and (...) anonymous. Surveys asked about reasons for, frequency of, and side effects of nonprescription misuse of prescription stimulants. Given the sensitive material, an opportunity to win one of ten $50 gift cards was used as an incentive. -/- Results Three hundred seventy-two (59.9%) students completed the survey from three disciplines (47.6% medical, 70.5% pharmacy, and 57.6% respiratory therapy). Overall, 11.3% of responders admitted to misusing prescription stimulants. There was more misuse by respiratory therapy students, although this was not statistically significant (10.9% medicine, 9.7% pharmacy, 26.3% respiratory therapy; P = .087). Reasons for prescription stimulant misuse included to enhance alertness/ energy (65.9%), to improve academic performance (56.7%), to experiment (18.2%), and to use recreationally/get high (4.5%). -/- Conclusions Prescription stimulant misuse was prevalent among participating students, but further research is needed to describe prevalence among future health care workers more generally. The implications and consequences of such misuse require further study across professions with emphasis on investigating issues of academic dishonesty (e.g., “cognitive enhancement”), educational quality, and patient safety or health care quality.

To explain the correct libertarian approach to immigration, a thought-experiment posits a minimal-state libertarian UK and then the introduction of several relevant anti-libertarian policies with their increasingly disastrous effects. It is argued that the reverse of these imagined policies, as far as is politically possible, must be the correct way forward. This framing is intended to counter the tendency for many articles to misapply libertarian principles to the current messy situation on the mistaken assumption that a state need only stop (...) interfering without rectifying or adjusting for its previous interferences. The relevant parts of various open-border texts are then criticised in light of this and for other errors, in particular for overlooking the likely huge scale of immigration as indicated by Gallup surveys. Additional criticisms are addressed in footnotes throughout. The conclusion outlines three broad options on immigration and suggests that directionally-libertarian policies are both more libertarian and practical than having states open their borders. The readers that might be interested in this subject matter include those engaging in libertarian philosophy, economics, and political theory. (shrink)

This replies to Block 2019 (B19), which responds to Lester 2014 (L14). The main issues in the, varyingly sized, sections are as follows. 1 Further explanations of critical rationalism, the theory of liberty, and problems with the non-aggression principle. 2.1 The relationships among law, morality, and libertarianism. 2.2 The objective invasiveness of low-level radiation and that it is therefore an initiated imposition (albeit trivial) if someone inflicts it on non-consenting people. 2.3 The objective and subjective aspects of initiated impositions; and (...) how clashes can be resolved. 2.4 How liberty relates to risk and self-ownership. 2.5 Libertarian initial acquisition versus absolute property rights by labour-mixing. 2.6 Organisational note. 2.7 Libertarianism and mens rea. 2.8 Libertarian rectification versus lex-talionis doubling. 2.9 Indirectly clashing rights, self-preservation, trespasser-hiker, flagpole-grasper, and landmine-layer. 2.10 A logical point is not a moral point. 2.11 Pacifism and libertarianism. 3.1 A weak criticism of utilitarianism. 3.2 Hedonometers; approximate interpersonal comparisons of utility imply libertarianism; what a libertarian is; libertarian rankings. 4. Libertarian philosophy versus propertarian dogma. Coda: the need to take seriously the philosophical problems with propertarian-justificationist libertarianism. (shrink)

This chapter first surveys general issues in the epistemic internalism / externalism debate: what is the distinction, what motivates it, and what arguments can be given on both sides. -/- The second part of the chapter will examine the internalism / externalism debate as regards to the specific case of the epistemology of memory belief.

The review cites the “Open Society” twice in its title—and is clearly pro-Popperian—but then fails to mention the fourteen-point list, and surrounding discussion, that explicitly compares Popper’s critical rationalism with anarcho-libertarianism (strong similarities) and liberal democracy (strong dissimilarities); EfL, pp.135-142. If the review had engaged more closely with the arguments of EfL and been more informed by the relevant social scientific literature, then it would probably have found the anarcho-libertarian case to be far more robust and realistic than such a (...) cursory dismissal can hope to refute.

The following essay responds to a draft article that criticises the theory of libertarian restitution in “Libertarian Rectification: Restitution, Retribution, and the Risk-Multiplier” (LR). The article was freely available to internet search engines. Hence, it seems fair and useful to reply to these very welcome objective criticisms. It is not intellectually relevant that its author might subsequently and subjectively have thought better of them, possibly as a result of the earlier version of this reply. Generally, the article misconstrues the position (...) on retribution in LR. Eventually, it makes apparent qualifications to its own position such that there does not seem to be any clear theoretical difference between the two on the central disputed issue. LR’s position is to explain and defend only the non-normative theory of libertarian restitution: full restoration or compensation to the damaged (initiatedly imposed on) party. But it is argued that this can include a retributive aspect if that is what the victim prefers. Moreover, such restitution will tend to act as a deterrent that maximises both overall interpersonal liberty (theorised as no initiated imposed costs) and human welfare (theorised as preference satisfaction).

The central classical liberal insight is that private property appears both to protect personal liberty and to promote general productivity. By way of philosophically clarifying this insight, Escape from Leviathan (EfL) posits the extreme classical liberal, or libertarian, Compatibility Thesis: there is no long-term, systemic, practical conflict among economic rationality, interpersonal liberty, human welfare, and private-property anarchy (i.e., four plausible and relevant theories of these that are presupposed, or entailed, by libertarianism and consonant social science). The review (Liberty, November 2002) (...) holds that this extreme version is probably false and suggests that perhaps even EfL’s author would agree. He (still) does not, although he remains open to argument. But what anyone happens to believe at any particular moment is a piece of fleeting biography that is irrelevant to the truth of the thesis or the soundness of the arguments in EfL. (shrink)

Contra critical rationalism, the response begins by referring to “the variety of internalist and externalist versions of foundationalism” (Liberty, December 2002). But it makes no attempt to explain or defend any of them. Hence, no further criticism is due here. The response then argues that, “The critical rationalist method seems to suggest that Lester’s extreme compatibility thesis is probably false” because—quoting Escape from Leviathan (EfL)—“bold universal theories might be false, and probably are” and yet “he doesn’t think the thesis is (...) probably false”. And so this is, by implication, an inconsistent belief. But the Compatibility Thesis (CT) is not one of the “bold universal theories” of science. The review and the response appear, at times, to assume that the CT is a bold universal theory about the perfect compatibility of applying the relevant conceptions, or theories, of rationality, liberty, welfare, and anarchy. Then, at other times, they assert that it is not bold at all but merely about definitions designed to be compatible. In fact, the CT asserts both that there are no theoretical incompatibilities among relevant and plausible versions of the theories, and that there are no actual long-term, systemic, and practical conflicts among applying them. That is still a bold theory (perhaps even most libertarians would disagree with it), but it’s not a universal thesis of perfect compatibility. And if it were good practice to reject a theory just because of its boldness, then all scientific theories would be immediately rejected without even trying to produce a falsification. In any case, as stated in the reply to the review, anyone’s mere beliefs are irrelevant to the truth of objective theories and the soundness of objective arguments. (shrink)

Under no circumstances should the absurd "right to roam‟ be incorporated into the legislation of this country. In reality, it is clearly a mere licence to trespass. Armed with the appropriate economic and philosophical arguments, we should eventually be able to offer an effective counter-attack with a movement for the "right to own‟ privately every last one of the state-controlled commons, heaths, hills, mountains, downs, woodlands, rivers, beaches, and footpaths. As a result, there will be no imposition on legitimate landowners (...) and more access to better resources for ramblers. (shrink)
