On the day before Christmas, 1170, Robert de Broc, member of a family of royal servants that had taken up King Henry II's fierce opposition to Thomas Becket, seized a horse bringing goods to the archbishop and cut off its tail. The next day, Archbishop Thomas noted this incident after his Christmas sermon when renewing his excommunication of Robert and several others, and he discussed it again four days later in his initial meeting with the men who would (...) shortly murder him. The excision of the horse's tail appears in five of the biographies of the martyr and subsequently in the national chronicles of Roger of Howden and Ralph of Diceto. Why did a minor act of cruelty inflicted on a horse seem so noteworthy to contemporaries? The sources recording it resound with the rich Latin vocabulary of shame: “dedecus, contemptus, ignominia, dehonestatio, opprobrium.” Robert's highly symbolic act, part of a pattern of harassment by the Brocs, was designed not just to threaten Becket but also to humiliate him.

Physicists routinely claim that the fundamental laws of physics are 'time symmetric' or 'time reversal invariant' or 'reversible'. In particular, it is claimed that the theory of quantum mechanics is time symmetric. But it is shown in this paper that the orthodox analysis suffers from a fatal conceptual error, because the logical criterion for judging the time symmetry of probabilistic theories has been incorrectly formulated. The correct criterion requires symmetry between future-directed laws and past-directed laws. This criterion is formulated and (...) proved in detail. The orthodox claim that quantum mechanics is reversible is re-evaluated. The property demonstrated in the orthodox analysis is shown to be quite distinct from time reversal invariance. The view of Satosi Watanabe that quantum mechanics is time asymmetric is verified, as well as his view that this feature does not merely show a de facto or 'contingent' asymmetry, as commonly supposed, but implies a genuine failure of time reversal invariance of the laws of quantum mechanics. The laws of quantum mechanics would be incompatible with a time-reversed version of our universe. (shrink)

Introduction to alternative ontology of mind and physics based on the multi-dimensional model of A Geometric Theory of the Universe (Holster).

The Schwarzschild solution (Schwarzschild, 1915/16) to Einstein’s General Theory of Relativity (GTR) is accepted in theoretical physics as the unique solution to GTR for a central-mass system. In this paper I propose an alternative solution to GTR, and argue it is both logically consistent and empirically realistic as a theory of gravity. This solution is here called K-gravity. The introduction explains the basic concept. The central sections go through the technical detail, defining the basic solution for the geometric tensor, the (...) Christoffel symbols, Ricci tensor, Ricci scalar, Einstein tensor, stress-energy tensor and density-pressure for the system. The density is integrated, and some consistency properties are demonstrated. A notable feature is the disappearance of the event horizon singularity, i.e. there are no black holes. So far this is for a single central mass. A generalization of the solution for multiple masses is then proposed. This is required to support K-gravity as a viable general interpretation of gravity. Then the question of empirical tests is discussed. It is argued that current observational data is almost but not quite sufficient to verify or falsify K-gravity. The Pioneer spacecraft trajectory data is of particular interest, as this is capable of providing a test; but the data (which originally showed anomalies that match K-gravity) is now uncertain. A new and very practical experiment is proposed to settle the matter. This would provide a novel test of GTR, and a novel test of the cause of the Pioneer anomalies. In conclusion, K-gravity has extensive ramifications for gravitational physics and for the philosophy of GTR and space-time. (shrink)

Literate Experience argues for the existence of certain shared patterns of intellectual association in the English seventeenth century, patterns that follow the outlines of Bacon’s project of epistemological reform. Bacon’s project offered a theory of how knowing as a private act could be transformed into a public one, an act related to the creation and maintenance of public authority. The question thus becomes, how did thinkers in the period reimagine civil society as a polity of knowledge? This study traces out (...) a variety of answers to that question, ranging from the Royal Society’s communal rhetoric to the work of four literary writers who, in a variety of ways, problematize the notion that political society exists as a community of shared knowledge.

The growth factor progranulin (PGRN) regulates cell division, survival, and migration. PGRN is an extracellular glycoprotein bearing multiple copies of the cysteine‐rich granulin motif. With PGRN family members in plants and slime mold, it represents one of the most ancient of the extracellular regulatory proteins still extant in modern animals. PRGN has multiple biological roles. It contributes to the regulation of early embryogenesis, to adult tissue repair and inflammation. Elevated PGRN levels often occur in cancers, and PGRN immunotherapy inhibits the (...) growth of hepatic cancer xenografts in mice. Recent studies have demonstrated roles for PGRN in neurobiology. An autosomal dominant mutation in GRN, the gene for PGRN, leads to neuronal atrophy in the frontal and temporal lobes, resulting in the disease frontotemporal lobar dementia. In this review we will discuss current knowledge of the multifaceted biology of PGRN. (shrink)

The current paper provides readers some clarifications on the nature and goals of mass media campaigns designed to promote organ donation. These clarifications were necessitated by an earlier essay by Rady et al. (Med Health Care Philos 15:229–241, 2012) who present erroneous claims that media promotion campaigns in this health context represent propaganda that seek to misrepresent the transplantation process. Information is also provided on the nature and relative power of media campaigns in organ donation promotion.

This book contains programmatic essays that focus on broad-ranging proposals for re-envisioning a discipline of comparative philosophy of religions.

:Behavioural public policy has come under fire by critics who claim that it is illiberal. Some authors recently suggest that there is a type of BPP – boosting – that is not as vulnerable to this normative critique. Our paper challenges this claim: there's no non-circular way to draw the distinction between nudge and boost that would make the normative difference required to infer the permissibility of a policy intervention from its type-membership. We consider two strategies: paradigmatic examples and causal (...) mechanisms. We conclude by sketching some suggestions about the right way to approach the normative issues. (shrink)

In this paper, our goal is to survey some of the legal contexts within which violence risk assessment already plays a prominent role, explore whether developments in neuroscience could potentially be used to improve our ability to predict violence, and discuss whether neuropredictive models of violence create any unique legal or moral problems above and beyond the well worn problems already associated with prediction more generally. In Violence Risk Assessment and the Law, we briefly examine the role currently played by (...) predictions of violence in three high stakes legal contexts: capital sentencing, civil commitment hearings, and sexual predator statutes. In Clinical vs. Actuarial Violence Risk Assessment, we briefly examine the distinction between traditional clinical methods of predicting violence and more recently developed actuarial methods, exemplified by the Classification of Violence Risk software created by John Monahan and colleagues as part of the MacArthur Study of Mental Disorder and Violence [1]. In The Neural Correlates of Psychopathy, we explore what neuroscience currently tells us about the neural correlates of violence, using the recent neuroscientific research on psychopathy as our focus. We also discuss some recent advances in both data collection and data analysis that we believe will play an important role when it comes to future neuroscientific research on violence. In The Potential Promise of Neuroprediction, we discuss whether neuroscience could potentially be used to improve our ability to predict future violence. Finally, in The Potential Perils of Neuroprediction, we explore some potential evidentiary, constitutional, and moral issues that may arise in the context of the neuroprediction of violence.

Despite the enormous influence of Michel Foucault in gender studies, social theory, and cultural studies, his work has been relatively neglected in the study of politics. Although he never published a book on the state, in the late 1970s Foucault examined the technologies of power used to regulate society and the ingenious recasting of power and agency that he saw as both consequence and condition of their operation. These twelve essays provide a critical introduction to Foucault's work on politics, exploring (...) its relevance to past and current thinking about liberal and neo-liberal forms of government. Moving away from the great texts of liberal political philosophy, this book looks closely at the technical means with which the ideals of liberal political rationalities have been put into practice in such areas as schools, welfare, and the insurance industry. This fresh approach to one of the seminal thinkers of the twentieth century is essential reading for anyone interested in social and cultural theory, sociology, and politics. (shrink)

Ever since its inception, the theory of evolution has been reified into an “-ism”: Darwinism. While biologists today tend to shy away from the term in their research, the term is still actively used in the broader academic and societal contexts. What exactly is Darwinism, and how precisely are its various uses and abuses related to the scientific theory of evolution? Some call for limiting the meaning of the term “Darwinism” to its scientific context; others call for its abolition; yet (...) others claim the term refers to a myth-like story. In this paper we propose a conceptually grounded overview of the term. We show how the scientific dimension of Darwinism feeds into, and is influenced by, guises of Darwinism as a methodology and as an ethically and politically charged “worldview”. The full meaning of Darwinism, as well as how this meaning has changed over time, can only be understood through the complex interaction between these three dimensions. (shrink)

Cancers rely on multiple, heterogeneous processes at different scales, pertaining to many biomedical fields. Therefore, understanding cancer is necessarily an interdisciplinary task that requires placing specialised experimental and clinical research into a broader conceptual, theoretical, and methodological framework. Without such a framework, oncology will collect piecemeal results, with scant dialogue between the different scientific communities studying cancer. We argue that one important way forward in service of a more successful dialogue is through greater integration of applied sciences (experimental and clinical) (...) with conceptual and theoretical approaches, informed by philosophical methods. By way of illustration, we explore six central themes: (i) the role of mutations in cancer; (ii) the clonal evolution of cancer cells; (iii) the relationship between cancer and multicellularity; (iv) the tumour microenvironment; (v) the immune system; and (vi) stem cells. In each case, we examine open questions in the scientific literature through a philosophical methodology and show the benefit of such a synergy for the scientific and medical understanding of cancer.

Social learning has been shown to be an evolutionarily adaptive strategy, but it can be implemented via many different cognitive mechanisms. The adaptive advantage of social learning depends crucially on the ability of each learner to obtain relevant and accurate information from informants. The source of informants’ knowledge is a particularly important cue for evaluating advice from multiple informants; if the informants share the source of their information or have obtained their information from each other, then their testimony is statistically (...) dependent and may be less reliable than testimony from informants who do not share information. In this study, we use a Bayesian model to determine how rational learners should incorporate the effects of shared information when learning from other people, conducting three experiments that examine whether human learners behave similarly. We find that people are sensitive to a number of different patterns of dependency, supporting the use of a sophisticated strategy for social learning that goes beyond copying the majority, and broadening the situations in which social learning is likely to be an adaptive strategy.

Words come into existence through a number of distinct processes including naming, semantic shifts, morphological productivity, and compounding. In accounting for the instantiation and individuation of word-types, two diachronic proposals termed Originalism and History are considered, which view word-types as emerging through a tokening act after which they are subsequently distinguished from others on the basis of having a unique event-like origin. In the following paper I elucidate two central tenets of Originalism and History, which I name essentialism and propagation. (...) Next, I demonstrate that each suffer considerable challenges from evidence pertaining to the systematic generativity of words grounded in universal features of human lexical cognition. A third diachronic theory named Originalism-Plus-Transfer (OPT) is then outlined. I argue that this more nuanced version of Originalism, in its present form, still lacks a thorough explanation of pivotal features of word generativity, word instantiation, and word individuation. A number of ‘synchronic’ constraints on word-hood—phonological, phonotactic, morpho-syntactic, and semantic—are put forward to ground the possible space for word generation. I conclude by exploring the viability of supplementing OPT with synchronic constraints and propose that a union between the two has the potential to provide OPT with greater empirical strength and predictive power. The upshot of this analysis is that there exists great programmatic value for diachronic theories in drawing on synchronic data and that the latter must feature as central to the philosophy of words if such work is to anticipate achieving explanatory adequacy.

This paper will discuss the origin of the human mind, and the qualitative discontinuity between human and animal cognition. We locate the source of this discontinuity within the language faculty, and thus take the origin of the mind to depend on the origin of the language faculty. We will look at one such proposal put forward by Hauser et al. (Science 298:1569-1579, 2002), which takes the evolution of a Merge trait (recursion) to solely explain the differences between human and animal (...) cognition. We argue that the Merge-only hypothesis fails to account for various aspects of the human mind. Instead we propose that the process of lexicalisation is also unique to humans, and that this process is key to explaining the vast qualitative differences. We will argue that lexicalisation is a process through which concepts are reformatted to be able to take on semantic features and to take part in grammatical relations. These are both necessary conditions for a grammatical mind and the increased ability to express conceptual content. We therefore propose a possible explanans for the discontinuity between humans and animals, namely that merge with lexicalisation (and consequently semantic features and grammatical relations) is a minimal requirement for the human mind.

The development of ethical guidelines and regulations regarding human subjects research has focused upon protection of vulnerable populations by relying on a limited typology of vulnerabilities. This results in several challenges: First, Institutional Review Boards struggle to interpret and apply the regulations because they are often vague and inconsistent. Second, applying the regulations to subjects who fit within multiple categories of vulnerability can lead to contradictions and the rejection of research that would be permissible if only one category were applicable. (...) Finally, some potential subjects have social and other context-based vulnerabilities that are not described in the federal regulations... (shrink)

At extreme altitude (>5,000 – 5,500 m), sustained hypoxia threatens human function and survival, and is associated with marked involuntary weight loss (cachexia). This seems to be a coordinated response: appetite and protein synthesis are suppressed, and muscle catabolism promoted. We hypothesise that, rather than simply being pathophysiological dysregulation, this cachexia is protective. Ketone bodies, synthesised during relative starvation, protect tissues such as the brain from reduced oxygen availability by mechanisms including the reduced generation of reactive oxygen species, improved mitochondrial (...) efficiency and activation of the ATP‐sensitive potassium (KATP) channel. Amino acids released from skeletal muscle also protect cells from hypoxia, and may interact synergistically with ketones to offer added protection. We thus propose that weight loss in hypoxia is an adaptive response: the amino acids and ketone bodies made available act not only as metabolic substrates, but as metabolic modulators, protecting cells from the hypoxic challenge.Also watch the Video Abstract.

Kriegel described the problem of intentional inexistence as one of the ‘perennial problems of philosophy’, 307–340, 2007: 307). In the same paper, Kriegel alluded to a modal realist solution to the problem of intentional inexistence. However, Kriegel does not state by name who defends the kind of modal realist solution he has in mind. Kriegel also points out that even what he believes to be the strongest version of modal realism does not pass the ‘principle of representation’ and thus modal (...) realism is not an adequate solution to the problem of intentional inexistence. In this paper, I respond to Kriegel by defending a modal realist solution that he did not consider in 2007, called ‘extended modal realism’. EMR is a version of modal realism where possible worlds are not completely isolated as they are under the Lewisian model. Rather, under EMR worlds are, in a way, spatiotemporally related. The fact EMR worlds are related allows EMR to sufficiently pass the principle of representation and thus can be deemed a legitimate solution to the problem of intentional inexistence. I conclude that either EMR can pass the principle of representation in some cases or, and I think the more sensible option, we give up on the principle of representation altogether. (shrink)

In this paper, we outline a framework for understanding the different kinds of knowledge required for medical practice and use this framework to show how scientism undermines aspects of this knowledge. The framework is based on Michael Polanyi’s claim that knowledge is primarily the product of the contemplations and convictions of persons and yet at the same time carries a sense of universality because it grasps at reality. Building on Polanyi’s ideas, we propose that knowledge can be described along two (...) intersecting “dimensions”: the tacit–explicit and the particular–general. These dimensions supersede the familiar “objective−subjective” dichotomy, as they more accurately describe the relationship between medical science and medical practice. Scientism, we argue, excludes tacit and particular knowledge and thereby distorts “clinical reality” and impairs medical practice and medical ethics. (shrink)

Foucault is often thought to have a great deal to say about the history of madness and sexuality, but little in terms of a general analysis of government and the state.; This volume draws on Foucault's own research to challenge this view, demonstrating the central importance of his work for the study of contemporary politics.; It focuses on liberalism and neo- liberalism, questioning the conceptual opposition of freedom/constraint, state/market and public/private that inform liberal thought.

A common objection against deflationism is that it cannot account for the fact that truth depends on reality. Consider the question ‘On what does the truth of the proposition that snow is white depend?’ An obvious answer is that it depends on whether snow is white. Now, consider what answer, if any, a deflationist can offer. The problem is as follows. A typical deflationary analysis of truth consists of biconditionals of the form ‘The proposition that p is true iff p’. (...) Such biconditionals tell us nothing about what the truth of the proposition that p might depend on. Therefore, it seems that a typical deflationist cannot give an answer. Since we know that an answer is available, this throws doubt over the adequacy of deflationism as an account of truth. Articulated here is a defence of deflationism against this objection. It is argued that although biconditionals of the sort mentioned do not explicitly state a dependency between truth and reality, they nevertheless convey one. The reason is that, given the context in which a deflationist invokes the biconditionals, such a dependency is implicated. A potential problem with this defence is that it leaves the deflationist still unable to give an account of what it is for truth to depend on reality. One might think that a deflationist can offer such an account by appealing to truthmaker theory but, it is argued below, truthmaker theory is unavailable to a deflationist. Instead, the deflationist should question the assumption that an account is available. (shrink)

The practice of burying objects with the dead is often claimed as some of the earliest evidence for religion, on the assumption that such “grave goods” were intended for the decedents’ use in the afterlife. However, this assumption is largely speculative, as the underlying motivations for grave‐good practices across time and place remain little understood. In the present work, we asked if explicit and implicit religious beliefs (particularly those concerning the continuity of personal consciousness after death) motivate contemporary grave‐good practices. (...) Across three studies, and comparing participants from the United States and NZ, we measured grave‐good deposition at actual or hypothetical funerals, finding that jewelry, photographs, and other items with sentimental, emotional, and relationship value were common. In addition, intuitive afterlife reasoning (as measured by people's attributions of mental states to the dead) motivated grave‐good decision‐making for about half (Study 2) or more (Study 3) people, including afterlife nonbelievers (“extinctivists”), while those who held explicit (i.e., stated) afterlife beliefs were more likely to participate in the practice. The decision to leave grave goods was also associated with magical contagion beliefs and a need for personal comfort, while other motivations, such as social signaling, were less common. Our results suggest that “afterlife use” is a common motivation for grave‐good practices, and that humans possess evolutionarily early intuitions about postdeath consciousness. (shrink)

Contemporary debates on obedience and consent, such as those between Thomas Senor and A. John Simmons, suggest that either political obligation must exist as a concept or there must be natural duty of justice accessible to us through reason. Without one or the other, de facto political institutions would lack the requisite moral framework to engage in legitimate coercion. This essay suggests that both are unnecessary in order to provide a conceptual framework in which obedience to coercive political institutions (...) can be understood. By providing a novel reading of Hobbes’s Leviathan, this article argues that both political obligation and a natural duty to justice are unnecessary to ground the ability of political institutions to engage in legitimate coercion. This essay takes issue with common readings of Hobbes which assume consent is necessary to generate obedience on the part of citizens, and furthermore that political obligation is critical for the success of political institutions. While the failure of the traditional Hobbesian narrative of a consenting individual would seem to suggest the Leviathan is indefensible as a project, this paper argues that the right of war in the state of nature was more central for Hob- bes’s understanding of political institutions than obligation. Furthermore, Hobbes provides an adequate defense of political institutions even if his arguments about consent, obligation and punishment are only rhetorical. In this way Hobbesian law is best understood as a set of practical requirements to avoid war, and not as moral requirements that individuals are bound to comply with. Thus Hobbesian political institutions are not vulnerable to contemporary philosophical anarchist criticisms about political obligation and political institutions as such. To develop this reading, I focus primarily on the Leviathan, including interpretations by Skinner, Kateb, Flathman, and Oakeshott. Ultimately, this argument provides insight into contem- porary political institutions of the state, citizenship, criminality, and the law in a world where political obligation has not been adequately justified.

Mestre, MacCann, Guil, and Roberts propose a model that suggests emotion regulation provides the mechanism through which ability emotional intelligence influences important outcomes. We argue that important nuance in our understanding of people’s choice of emotion regulation strategy can be gained by incorporating personality constructs such as trait emotional intelligence within this model.

The informative and engaging essays in the foregoing collection suggest several interesting concepts that deserve further research and reflection. Over the past decade, the “social construction of technology” has become a concept often explored by historians (Bijker, Hughes, and Pinch 1987). Even though it has performed the useful function of discrediting technological determinism, the concept suggests too narrow a set of influences that shape technology. Two other concept, “nature-shaped technology” and “culture-shaped technology,” convey the character of technology more effectively. To (...) designate “nature” as a shaper of technology reminds us that in a relatively prisine world the designer of technology negotiates with natural forces more than with human-built ones. To see culture as a shaper of technology suggests a broader range of influences affecting technology, not simply the social. “Shaping” conveys the notion of influence and avoids that of determinism better than “construction.”.

We report on five experiments investigating response choices and response times to simple science questions that evoke student “misconceptions,” and we construct a simple model to explain the patterns of response choices. Physics students were asked to compare a physical quantity represented by the slope, such as speed, on simple physics graphs. We found that response times of incorrect answers, resulting from comparing heights, were faster than response times of correct answers comparing slopes. This result alone might be explained by (...) the fact that height was typically processed faster than slope for this kind of task, which we confirmed in a separate experiment. However, we hypothesize that the difference in response time is an indicator of the cause of the response choice. To support this, we found that imposing a 3-s delay in responding increased the number of students comparing slopes on the task. Additionally a significant proportion of students recognized the correct written rule , but on the graph task they incorrectly compared heights. Finally, training either with repetitive examples or providing a general rule both improved scores, but only repetitive examples had a large effect on response times, thus providing evidence of dual paths or processes to a solution. Considering models of heuristics, information accumulation models, and models relevant to the Stroop effect, we construct a simple relative processing time model that could be viewed as a kind of fluency heuristic. The results suggest that misconception-like patterns of answers to some science questions commonly found on tests may be explained in part by automatic processes that involve the relative processing time of considered dimensions and a priority to answer quickly.

Research about the Olympic Games has primarily focused on preparing athletes for competition. Less attention has been paid to the post-Olympic-phase and athlete well-being during this time. This study explored Australian Olympic athletes’ experiences following the conclusion of the 2016 Rio Olympic Games, including the factors that may have contributed to or challenged their well-being during this time. Eighteen athletes participated in semi-structured interviews and thematic analysis revealed that when Olympic performance appraisal met prior expectations, when athletes planned for a (...) return to work or study, and when support from a variety of sources was readily available, this positively influenced athletes’ well-being during the POP. When these factors were not in place, more challenging post-Games experiences were present, and well-being was compromised. The findings contribute to the broader literature on elite athlete well-being and at an applied level, may be used to inform targeted programs that focus on supporting athletes after an Olympic campaign.

Systematic study of the intersection of ethics consultation services and solid organ transplants and recipients can identify and illustrate ethical issues that arise in the clinical care of these patients, including challenges beyond resource allocation. This was a single-centre, retrospective cohort study of all adult ethics consultations between January 1, 2007, and December 31, 2017, at a large academic medical centre in the north-eastern United States. Of the 880 ethics consultations, sixty (6.8 per cent ) involved solid organ transplant, thirty-nine (...) (65.0 per cent) for candidates and twenty-one (35.0 per cent ) for recipients. Ethics consultations were requested for 4.3 per cent of heart, 4.9 per cent of lung, 0.3 per cent of liver, and 0.3 per cent of kidney transplant recipients over the study period. Nurses were more likely to request ethics consultations for recipients than physicians (80.0 per cent vs 20.0 per cent, p = 0.006). The most common reason for consultation among transplant candidates was discussion about intensity of treatment or goals of care after the patient was not or was no longer a transplant candidate. The most common reason for ethics consultation among transplant recipients was disagreement between transplant providers and patients/families/non-transplant healthcare professionals over the appropriate intensity of treatment for recipients. Very few consultations involved questions about appropriate resource allocation. Ethics consultants involved in these cases most often navigated communication challenges between transplant and non-transplant healthcare professionals and patients and families. (shrink)

The ArgumentMany inventors, engineers, and scientists think in verbal images. Elmer Sperry (1860–1930), a noted American inventor, was able to “operate” in his mind's eye the machines he was developing. For inventors, engineers, and experimental scientists, visualization is often followed by construction of a physical model of the invention, which can be an experimental apparatus. The model, or apparatus, is then tested in increasingly complex environments and changes are made in the physical artifact until it is ready to be used. (...) Examples of this process of development are Sperry's development of a ship stabilizer for the U.S. Navy and a revolving mirror to be used by Albert Michelson in the determination of the speed of light. Thomas Edison called experimentation his development of an invention through the building and testing of a series of models. So, both scientists and inventors experiment. They are not discovering the “secrets of nature”: they are observing how artifacts – their physical creations – behave. These physical models of thought reflect the characteristics of the tools with which they were made. They are socially constructed, as well. (shrink)
