Progressive supranuclear palsy is a movement disorder with prominent tau neuropathology. Brain diseases with abnormal tau deposits are called tauopathies, the most common of which is Alzheimer's disease. Environmental causes of tauopathies include repetitive head trauma associated with some sports. To identify common genetic variation contributing to risk for tauopathies, we carried out a genome-wide association study of 1,114 individuals with PSP and 3,247 controls followed by a second stage in which we genotyped 1,051 cases and 3,560 controls for the (...) stage 1 SNPs that yielded P ≤ 10-3. We found significant previously unidentified signals associated with PSP risk at STX6, EIF2AK3 and MOBP. We confirmed two independent variants in MAPT affecting risk for PSP, one of which influences MAPT brain expression. The genes implicated encode proteins for vesicle-membrane fusion at the Golgi-endosomal interface, for the endoplasmic reticulum unfolded protein response and for a myelin structural component. © 2011 Nature America, Inc.

In this paper, we examine the lawfulness of a proposal to provide elective ventilation to incompetent patients who are potential organ donors. Under the current legal framework, this depends on whether the best interests test could be satisfied. It might be argued that, because the Mental Capacity Act 2005 (UK) (and the common law) makes it clear that the best interests test is not confined to the patient's clinical interests, but extends to include the individual's own values, wishes and beliefs, (...) the proposal will be in the patient's best interests. We reject this claim. We argue that, as things currently stand, the proposal could not lawfully be justified as a blanket proposition by reference to the best interests test. Accordingly, a modification of the law would be necessary to render the proposal lawful. We conclude with a suggestion about how that could be achieved. (shrink)

This innovative collection offers one of the first analyses of criminologies of the military from an interdisciplinary perspective. While some criminologists have examined the military in relation to the area of war crimes, this collection considers a range of other important but less explored aspects such as private military actors, insurgents, paramilitary groups and the role of military forces in tackling transnational crime. Drawing upon insights from criminology, this book's editors also consider the ways the military institution harbours criminal activity (...) within its ranks and deals with prisoners of war. The contributions, by leading experts in the field, have a broad reach and take a truly global approach to the subject. (shrink)

The modern slavery literature engages with history in an extremely limited fashion. Our paper demonstrates to the utility of historical research to modern slavery researchers by explaining the rise and fall of the ethics-driven market category of “free-grown sugar” in nineteenth-century Britain. In the first decades of the century, the market category of “free-grown sugar” enabled consumers who were opposed to slavery to pay a premium for a more ethical product. After circa 1840, this market category disappeared, even though considerable (...) quantities of slave-grown sugar continued to arrive into the UK. We explain the disappearance of the market category. Our paper contributes to the on-going debates about slavery in management by historicizing and thus problematizing the concept of “slavery”. The paper challenges those modern slavery scholars who argue that lack of consumer knowledge about product provenance is the main barrier to the elimination of slavery from today’s international supply chains. The historical research presented in this paper suggests that consumer indifference, rather than simply ignorance, may be the more fundamental problem. The paper challenges the optimistic historical metanarrative that pervades much of the research on ethical consumption. It highlights the fragility of ethics-driven market categories, offering lessons for researchers and practitioners seeking to tackle modern slavery. (shrink)

Published in 1918, _The View of Life_ is Georg Simmel’s final work. Famously deemed “the brightest man in Europe” by George Santayana, Simmel addressed a variety of topics across his essayistic writings, which have influenced scholars in aesthetics, ethics, epistemology, and sociology. Nevertheless, a set of core issues emerged over the course of his career, most centrally the genesis, structure, and transcendence of social and cultural forms and the nature and genesis of authentic individuality. Composed in the years before his (...) death, _The View of Life_ was, according to Simmel, his “testament,” a capstone work of profound metaphysical inquiry intended to formulate his conception of life in its entirety. Now Anglophone readers can at last read in full the work that shaped the argument of Heidegger’s _Being and Time_ and whose extraordinary impact on European intellectual life between the wars was extolled by Jürgen Habermas. Presented alongside these seminal essays are aphoristic fragments from Simmel’s last journal, providing a beguiling look into the mind of one of the twentieth century’s greatest thinkers. (shrink)

In this work, I attempt a four-part task: to explicate Heidegger's notion of the Fourfold, to show its necessary relation to technology, to think the limit that separates these, and to show how this constellation of the Fourfold and technology escapes from the "metaphysics of presence" with which Heidegger has been charged. ;1. The Fourfold is the belonging together of Earth, Sky, Mortals, and Divinities. Heidegger inherits the components from Holderlin, but transforms then in his thought. The gathering of these (...) four goes to make up the presencing of a singular and delimited entity . Such a thing exists as unique and irreplaceable. ;2. This singular mode of presence is only understandable against the background of limitless technological circulation. Influenced by Ernst Junger, Heidegger sees technology as setting into place a world of instantaneous replacement and sameness. The name for this manner of replaceable presence is "Bestand ." ;3. The unworld of technology is no simple "opposite" to the Fourfold, however. Rather the two modes of presence belong together. Heidegger repeatedly emphasizes how there can never be a complete loss of world in the enframing of technology. Conversely, the Fourfold is never free of the Bestand. A play of revelation and concealment is operative here and intimately related to Heidegger's new notion of essence. I examine this intricate and intimate co-belonging of technology and the Fourfold. ;4. This interpretation is used to counter the charge that Heidegger would think in terms of metaphysical presence, i.e., in terms of complete, self-present, and pure presence. Such a charge is leveled in the early work of Jacques Derrida. I show that Heidegger's thinking is already a thought of the trace. Since there is consequently no total presence or absence for Heidegger , there can be no simple overcoming of metaphysics either. Metaphysics cannot be so easily left behind, but must undergo a transformation . This is nothing more than a recognition of the trace and its place at the limit of singular, finite existence. ;The first chapter treats the circulation of technology, the remaining four address in series the elements of the Fourfold.

What job should authorities give to review boards? We are grateful to Soren Holm, Rosamond Rhodes, Julian Savulescu and G Owen Schaefer for their thoughtful commentaries on our answer.1–4 Here we add to the discussion. Let us summarise the claims for which we argued.5 Relevant authorities can task boards with review for consistency with duly established code, thereby making code-consistent activities apt for approval and code-inconsistent activities apt for rejection. They can instead task boards with review for ethical acceptability, making (...) ethically acceptable activities apt for approval and ethically unacceptable activities apt for rejection. For every proposal a board might consider, these two different jobs establish different review bases, and their approvals and rejections also sometimes conflict. Some international and national statements require ECR, others instead require CCR, and others again seem either to require both or just to run the two together. Those responsible for these statements should make them clearer and better aligned here. For reasons of practicality, publicity and separation of powers, authorities do better to task boards with CCR and not ECR. These arguments also count against establishing any code with content that in effect collapses CCR into ECR. If our arguments withstand robust scrutiny, authorities should also remove ‘ethics’ and cognate terms from the names of these boards and their review activities and emphasise code expertise not ethics expertise in the required skill sets of boards. Our article noted that ‘ethical considerations informed the genesis of these boards and express their aspirations’. Rhodes similarly notes: ‘the authors and endorsers of research ethics codes, declarations and regulations … articulating the ethical standards for conducting human subject research’ and ‘This framework embeds the ethical parameters of human subject research into the moral missions of institutions’. Schaefer too …. (shrink)

This paper is a revalidation of Oliver Sacks's role in the development of medicine's narrative turn and, as such, a reinterpretation of the history of narrative in medicine. It suggests that, from the late 1960s, Sacks pioneered in his ‘Romantic Science’ a new medical mode that reunited the seemingly incommensurable art and science of medicine while also offering a way for medical humanities to shape clinical reasoning more effectively.

In this paper I expound and criticise the arguments of two leading exponents of critical ecological feminism. According to critical ecological feminism responsibility for the oppressions of the natural world and the oppressions of racism and sexism can be traced to a logic of domination that is based on suspect value dualities and presupposes an unacceptable ‘moral extensionism’. I argue firstly that critical ecological feminism's critique of value dualism presupposes the truth of the thesis that humans and non‐humans are morally (...) equal, a thesis for which it offers no persuasive arguments . Secondly I maintain that moral extensionism, contrary to the claims of critical ecological feminism, can support a genuine respect for the natural world. Finally I suggest that the arguments for one version of critical ecological feminism, in order to be made convincing, themselves require the truth of moral extensionism. (shrink)

Hirst always highlighted knowledge when reflecting on the school curriculum. He replaced his early focus on liberal education, the development of mind and theoretical knowledge by emphasizing the practical and practices as a curriculum starting point and for the framing of educational aims. In this paper I explore links between Hirst’s philosophical treatment of knowledge and some currently contested aspects of UK government education policies. I also note some ways in which his work relates to selected present-day debates in philosophy (...) of education. Examples of UK government policy will include Ofsted’s definition of learning as a ‘change in long-term memory’ and the ways in which they place ‘logical sequencing’ at the heart of teaching, learning, and curriculum. Their learning definition treats knowledge as an individual asset rather than something about individuals as embedded in the social world of practices, a perspective more in keeping with Hirst’s later views. The critique of individualistic notions of knowledge and learning includes some explorations of how learners move into the ‘space of reasons’. Where I draw attention to relationships between Hirst’s thought and contemporary philosophy of education debates, I do not always draw any definite conclusions. (shrink)

Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and (...) On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)

Weak panpsychism, the view that mindlike qualities are wide-spread in nature, has recently been argued for by the prominent ecofeminist Val Plumwood and has been used by her to ground an ethic of respect for nature. This ethic advocates a principle of respect for difference, the rejection of moral hierarchy and the inclusion of plants, mountains, rivers and ecosystems within the moral community. I argue that weak panpsychism cannot, convincingly, justify the rejection of moral hierarchy, as it is compatible with (...) it. Also the intentional criterion of mind, employed by weak panpsychism, which includes teleology, has the counter-intuitive implication of giving machines moral status. I cast doubt on the claims that (i) intentionality is a necessary condition for moral status and that (ii) it is sufficient for the ascription of agency. It is suggested that any account of intentionality that allows it to be predicated of mountains, rivers etc. would be widely, and correctly regarded as a reduction of that account. Finally an aesthetic reinterpretation of weak panpsychism is offered. (shrink)

In December 2013, the Nonhuman Rights Project (NhRP) filed a petition for a common law writ of habeas corpus in the New York State Supreme Court on behalf of Tommy, a chimpanzee living alone in a cage in a shed in rural New York (Barlow, 2017). Under animal welfare laws, Tommy’s owners, the Laverys, were doing nothing illegal by keeping him in those conditions. Nonetheless, the NhRP argued that given the cognitive, social, and emotional capacities of chimpanzees, Tommy’s confinement constituted (...) a profound wrong that demanded remedy by the courts. Soon thereafter, the NhRP filed habeas corpus petitions on behalf of Kiko, another chimpanzee housed alone in Niagara Falls, and Hercules and Leo, two chimpanzees held in research facilities at Stony Brook University. Thus began the legal struggle to move these chimpanzees from captivity to a sanctuary, an effort that has led the NhRP to argue in multiple courts before multiple judges. The central point of contention has been whether Tommy, Kiko, Hercules, and Leo have legal rights. To date, no judge has been willing to issue a writ of habeas corpus on their behalf. Such a ruling would mean that these chimpanzees have rights that confinement might violate. Instead, the judges have argued that chimpanzees cannot be bearers of legal rights because they are not, and cannot be persons. In this book we argue that chimpanzees are persons because they are autonomous. (shrink)

It is argued that expressivists can solve their problems in accounting for the unity and autonomy of logic – logic is topic independent and does not derive from a general ‘logic’ of mental states – by adopting an analysis of the logical connectives that takes logically complex sentences to express complex combinations of simple attitudes like belief and disapproval and dispositions to form such simple attitudes upon performing suppositional acts, and taking acceptance and rejection of sentences to be the common (...) mental denominator in descriptive and evaluative discourse, and structural requirements governing these to be the basis for logic. Such an account requires that attitudes like belief, intention and disapproval can come in hypothetical mode – plausibly linked to the capacity to mentally simulate or emulate one's own attitudes – and, if correct, suggests that these form the basic building blocks for our capacity to understand logically complex sentences.

Critical Realism and Marxism addresses controversial debates, revealing a potentially fruitful relationship; deepening our understanding of the social world and contibuting towards eliminating barbarism in contemporary capitalism.

We submit this brief in support of the Nonhuman Rights Project’s efforts to secure habeas corpus relief for the elephant named Happy. We reject arbitrary distinctions that deny adequate protections to other animals who share with protected humans relevantly similar vulnerabilities to harms and relevantly similar interests in avoiding such harms. We strongly urge this Court, in keeping with the best philosophical standards of rational judgment and ethical standards of justice, to recognize that, as a nonhuman person, Happy should be (...) released from her current confinement and transferred to an appropriate elephant sanctuary, pursuant to habeas corpus.

In this brief, we argue that there is a diversity of ways in which humans (Homo sapiens) are ‘persons’ and there are no non-arbitrary conceptions of ‘personhood’ that can include all humans and exclude all nonhuman animals. To do so we describe and assess the four most prominent conceptions of ‘personhood’ that can be found in the rulings concerning Kiko and Tommy, with particular focus on the most recent decision, Nonhuman Rights Project, Inc v Lavery.

We submit this brief in support of the Nonhuman Rights Project’s efforts to secure habeas corpus relief for the elephant named Happy. The Supreme Court, Bronx County, declined to grant habeas corpus relief and order Happy’s transfer to an elephant sanctuary, relying, in part, on previous decisions that denied habeas relief for the NhRP’s chimpanzee clients, Kiko and Tommy. Those decisions use incompatible conceptions of ‘person’ which, when properly understood, are either philosophically inadequate or, in fact, compatible with Happy’s personhood.

Statements containing epistemic modals (e.g., “by spring 2023 most European countries may have the Covid-19 pandemic under control”) are common expressions of epistemic uncertainty. In this paper, previous published findings (Knobe & Yalcin, 2014; Khoo & Phillips, 2018) on the opposition between Contextualism and Relativism for epistemic modals are re-examined. It is found that these findings contain a substantial degree of individual variation. To investigate whether participants differ in their interpretation of epistemic modals, an experiment with multiple phases and sessions (...) is used to classify participants according to the three semantic theories of Relativism, Contextualism, and Objectivism. Through this study, some of the first empirical evidence for the kind of truth-value shifts postulated by semantic Relativism is presented. It is furthermore found that participants’ disagreement judgments match their truth evaluations and that participants are capable of distinguishing between truth and justification. In a second experimental session, it is investigated whether participants thus classified follow the norm of retraction which Relativism uses to account for argumentation with epistemic modals. Here the results are less favorable for Relativism. In a second experiment, these results are replicated and the normative beliefs of participants concerning the norm of retraction are investigated following work on measuring norms by Bicchieri (2017). Again, it is found that on average participants show no strong preferences concerning the norm of retraction for epistemic modals. Yet, it was found that participants who had committed to Objectivism and had training in logics applied the norm of retraction to might-statements. These results present a substantial challenge to the account of argumentation with epistemic modals presented in MacFarlane (2014), as discussed.

A semantics is presented for belief-revision in the face of common announcements to a group of agents that have beliefs about each other's beliefs. The semantics is based on the idea that possible worlds can be viewed as having an internal structure, representing the belief independent features of the world, and the respective belief states of the agents in a modular fashion. Modularity guarantees that changing one aspect of the world (a belief independent feature or a belief state) has no (...) effect on any other aspect of the world. This allows us to employ an AGM-style selection function to represent revision. The semantics is given a complete axiomatisation (identical to the axiomatisation found by Gerbrandy and Groeneveld for a semantics based on non-wellfounded set theory) for the special case of expansion.

It is argued that the "inner" negation $\mathord{\sim}$ familiar from 3-valued logic can be interpreted as a form of "conditional" negation: $\mathord{\sim}$ is read '$A$ is false if it has a truth value'. It is argued that this reading squares well with a particular 3-valued interpretation of a conditional that in the literature has been seen as a serious candidate for capturing the truth conditions of the natural language indicative conditional (e.g., "If Jim went to the party he had a (...) good time"). It is shown that the logic induced by the semantics shares many familiar properties with classical negation, but is orthogonal to both intuitionistic and classical negation: it differs from both in validating the inference from $A \rightarrow \nega B$ to $\nega(A\rightarrow B)$ to.

Ever since [4], systems of spheres have been considered to give an intuitive and elegant way to give a semantics for logics of theory- or belief- change. Several authors [5, 11] have considered giving up the rather strong assumption that systems of spheres be linearly ordered by inclusion. These more general structures are called hypertheories after [8]. It is shown that none of the proposed logics induced by these weaker structures are compact and thus cannot be given a strongly complete (...) axiomatization in a finitary logic. Complete infinitary axiomatizations are given for several intuitive logics based on hypertheories that are not linearly ordered by inclusion. (shrink)

A globally expressivist analysis of the indicative conditional based on the Ramsey Test is presented. The analysis is a form of ‘global’ expressivism in that it supplies acceptance and rejection conditions for all the sentence forming connectives of propositional logic (negation, disjunction, etc.) and so allows the conditional to embed in arbitrarily complex sentences (thus avoiding the Frege–Geach problem). The expressivist framework is semantically characterized in a restrictor semantics due to Vann McGee, and is completely axiomatized in a logic dubbed (...) ICL (‘Indicative Conditional Logic’). The expressivist framework extends the AGM (after Alchourron, Gärdenfors, Makinson) framework for belief revision and so provides a categorical (‘yes’–‘no’) epistemology for conditionals that complements McGee’s probabilistic framework while drawing on the same semantics. The result is an account of the semantics and acceptability conditions of the indicative conditional that fits well with the linguistic data (as pooled by linguists and from psychological experiments) while integrating both expressivist and semanticist perspectives.

Expert skill in music performance involves an apparent paradox. On stage, expert musicians are required accurately to retrieve information that has been encoded over hours of practice. Yet they must also remain open to the demands of the ever-changing situational contingencies with which they are faced during performance.

For (...) Chaffin, expert skill in music performance relies solely upon overarching mental representations, while, for Dreyfus, such representations are needed only by novices, while experts rely on a more embodied form of coping. Between Chaffin and Dreyfus sit the Noices, who argue that both overarching cognitive structures and embodied processes underlie expert skill. We then present the Applying Intelligence to the Reflexes (AIR) approach?a differently nuanced model of expert skill aligned with the integrative spirit of the Noices? research.

We offer data from recent doctoral research conducted by the first author of this article to demonstrate at a practical level the usefulness of the AIR approach when attempting to understand the complexities of expert skill in music performance.

It is argued that indicative conditionals are best viewed as having truth conditions (and so they are in part factual) but that these truth conditions are ‘gappy’ which leaves an explanatory gap that can only be filled by epistemic considerations (and so indicative conditionals are in part epistemic). This dual nature of indicative conditionals gives reason to rethink the relationship between logic viewed as a descriptive discipline (focusing on semantics) and logic viewed as a discipline with a normative import (focusing (...) on epistemic notions such as ‘reasoning’, ‘beliefs’ and ‘assumptions’). In particular, it is argued that the development of formal models for epistemic states can serve as a starting point for exploring logic when viewed as a normative discipline. (shrink)

Conditionals that contain a modality in the consequent give rise to a particular semantic phenomenon whereby the antecedent of the conditional blocks possibilities when interpreting the modality in the consequent. This explains the puzzling logical behaviour of constructions like "If you don't buy a lottery ticket, you can't win", "If you eat that poison, it is unlikely that you will survive the day" and "If you kill Harry, you ought to kill him gently". In this paper it is argued that (...) a semantic version of the Ramsey Test provides a key in the analysis of such constructions. The logic for this semantics is axiomatized and some examples are studied, among them a well-known puzzle for contrary-to-duty obligations. (shrink)

An alleged counterexample to causal decision theory, put forward by Andy Egan, is studied in some detail. It is argued that Egan rejects the evaluation of causal decision theory on the basis of a description of the decision situation that is different from—indeed inconsistent with—the description on which causal decision theory makes its evaluation. So the example is not a counterexample to causal decision theory. Nevertheless, the example shows that causal decision theory can recommend unratifiable acts which presents a problem (...) in the dynamics of intentions. It is argued that we can defuse this problem if we hold that decision theory is a theory of rational decision making rather than a theory of rational acts. It is shown how decisions can have epistemic side-effects that are not mediated by the act and that there are cases where one can only bring oneself to perform the best act by updating by imaging rather than by conditioning. This provides a pragmatic argument for updating by imaging rather than by conditioning in these cases. (shrink)
