Using medical advances to enhance human athletic, aesthetic, and cognitive performance, rather than to treat disease, has been controversial. Little is known about physicians? experiences, views, and attitudes in this regard. We surveyed a national sample of physicians to determine how often they prescribe enhancements, their views on using medicine for enhancement, and whether they would be willing to prescribe a series of potential interventions that might be considered enhancements. We find that many physicians occasionally prescribe enhancements, but doctors hold (...) nuanced and ambiguous views of these issues. Most express concerns about the potential effects of enhancements on social equity, yet many also believe specific enhancements that are safe and effective should be available but not covered by insurance. These apparently contradictory views might reflect inherent tensions between the values of equity and liberty, which could make crafting coherent social policies on medical enhancements challenging.

Prevailing theories of the neural basis of at least a subset of individuals with autism spectrum disorder include an imbalance of excitatory and inhibitory neurotransmission. These circuitry imbalances are commonly probed in adults using auditory steady-state responses to elicit coherent electrophysiological responses from intact circuitry. Challenges to the ASSR methodology occur during development, where the optimal ASSR driving frequency may be unknown. An alternative approach is the amplitude-modulated sweep in which the amplitude of a tone is modulated as a sweep (...) from 10 to 100 Hz over the course of ∼15 s. Phase synchrony of evoked responses, measured via intra-trial coherence, is recorded as a function of frequency. We applied such AM sweep stimuli bilaterally to 40 typically developing and 80 children with ASD, aged 6–18 years. Diagnoses were confirmed by DSM-5 criteria as well as autism diagnostic observation schedule observational assessment. Stimuli were presented binaurally during MEG recording and consisted of 20 AM swept stimuli with a duration of ∼30 s each. Peak intra-trial coherence values and peak response frequencies of source modeled responses were examined. First, the phase synchrony or inter-trial coherence of the ASSR is diminished in ASD; second, hemispheric bias in the ASSR, observed in typical development, is maintained in ASD, and third, that the frequency at which the peak response is obtained varies on an individual basis, in part dependent on age, and with altered developmental trajectories in ASD vs. TD. Finally, there appears an association between auditory steady-state phase synchrony and clinical assessment of language ability/impairment. We concluded that the AM sweep stimulus provides a mechanism for probing ASSR in an unbiased fashion, during developmental maturation of peak response frequency, peak frequencies vary, in part due to developmental age, and importantly, ITC at this peak frequency is diminished in ASD, with the degree of ITC disturbance related to clinically assessed language impairment.

The extended Church-Turing thesis posits that any computable function can be calculated efficiently by a probabilistic Turing machine. If this thesis held true, the global effort to build quantum computers might ultimately be unnecessary. The thesis would however be strongly contradicted by a physical device that efficiently performs a task believed to be intractable for classical computers. BosonSampling - the sampling from a distribution of n photons undergoing some linear-optical process - is a recently developed, and experimentally accessible example of (...) such a task [1].

In Laudato si’, Pope Francis calls for an “ecological conversion,” inviting his readers to abandon the interspecies violence characterizing our “throwaway culture,” which reductively and lamentably instrumentalizes the earth. Yet, while Francis recognizes the problems of systemic anthropogenic animal violence and economic agricultural imperialisms inherent in corporatized food production systems individually, he does not address the intersectional nature of these issues. Neither does he address the most obvious ethical conflicts arising in industrialized food production: the conflicts focused on meat eating. (...) In this article, we explore what Laudato si’ means for the ethics of eating well with reference to industrialized animal agriculture and its relation to animal dignity and environmental concerns. After analyzing Laudato si’ on the economics and ethics of food, animal well-being, and ecological ethics, we discuss the possibilities and limitations of Catholic vegetarianism in the context of traditional ascetic fasting practices and a discussion of ecological lamentation.

Some individuals facing dementia contemplate hastening their own death: weighing the possibility of living longer with dementia against the alternative of dying sooner but avoiding the later stages of cognitive and functional impairment. This weighing resonates with an ethical and legal consensus in the United States that individuals can voluntarily choose to forgo life‐sustaining interventions and also that medical professionals can support these choices even when they will result in an earlier death. For these reasons, whether and how a terminally (...) ill individual can choose to control the timing of their death is a topic that cannot be avoided when considering the dementia trajectory. With a focus on the U.S. context, this landscape review considers the status of provisions that would legally permit people facing dementia to hasten death with appropriate support from medical professionals. This review can be used to plan and guide clinical and legal practitioner discussion and policy development concerning evolving questions not fully covered by existing medical decision‐making provisions.

The moral right to keep and bear arms is entailed by the moral right of self-defense. We argue that the ownership and use of firearms is a reasonable means of exercising these rights. Given their defensive value, there is a strong presumption in favor of enacting civil rights to keep and bear arms ranging from handguns to ‘assault rifles.’ Thus, states are morally obliged as a matter of justice to recognize basic liberties for firearm ownership and usage. Throughout this paper (...) we build upon the relevant criminological and social science research in addition to the work of other philosophers who have in recent years argued in favor of gun rights. Although we believe the statistical evidence supports our case, our argument is primarily non-consequentialist. We do, however, address consequentialist objections in the last section of this paper.

Human cooperation is highly unusual. We live in large groups composed mostly of non-relatives. Evolutionists have proposed a number of explanations for this pattern, including cultural group selection and extensions of more general processes such as reciprocity, kin selection, and multi-level selection acting on genes. Evolutionary processes are consilient; they affect several different empirical domains, such as patterns of behavior and the proximal drivers of that behavior. In this target article, we sketch the evidence from five domains that bear on (...) the explanatory adequacy of cultural group selection and competing hypotheses to explain human cooperation. Does cultural transmission constitute an inheritance system that can evolve in a Darwinian fashion? Are the norms that underpin institutions among the cultural traits so transmitted? Do we observe sufficient variation at the level of groups of considerable size for group selection to be a plausible process? Do human groups compete, and do success and failure in competition depend upon cultural variation? Do we observe adaptations for cooperation in humans that most plausibly arose by cultural group selection? If the answer to one of these questions is “no,” then we must look to other hypotheses. We present evidence, including quantitative evidence, that the answer to all of the questions is “yes” and argue that we must take the cultural group selection hypothesis seriously. If culturally transmitted systems of rules (institutions) that limit individual deviance organize cooperation in human societies, then it is not clear that any extant alternative to cultural group selection can be a complete explanation.

One day, Matthew Eaton was walking through an impromptu animal shelter display at his local pet store when suddenly an eight-month-old kitten dug his claws into Eaton’s flesh. Eaton recognized that the “eyes of this cat and the curve of his claw” compelled a response analogous to those found in the writings of Buber, Levinas, and Derrida. And not just Eaton but a whole community of theologians have found themselves in an encounter with particular places and animals that demands (...) rich theological reflection. Eaton enlisted fellow editors Harvie and Bechtel to collect the essays in this volume, in which theologians listen to horses, rats, snakes, cats, dogs, and the earth itself, who become new theological voices demanding a response. In this volume, the voice of the more-than-human world is heard as making theology possible. These essays suggest that what we say theologically represents not simply ideas of our own making subsequently superimposed onto the natural world through our own discovery, but rather flow from an expressive Earth.

While working on various medieval philosophers, I have noticed an affinity between their remarks on the reasonableness of accepting propositions that are not matters of proof and strict deduction and St. John Henry Newman’s remarks that we accept unconditionally and rightly everyday ordinary propositions without calibrating them to demonstrable arguments. In particular, Cardinal Matthew of Aquasparta and Blessed John Duns Scotus both claim there is a sense in which assent to everyday propositions is tantamount to knowledge, even though there (...) is no adequate argumentation or demonstrative reasoning compelling us to assent to such propositions. Newman’s distinction between notional and real apprehension of propositions, notional and real assents, and his insistence on the existence of real assents to propositions that are not necessarily proved, or in some cases provable, seem, at first glance, a case parallel to that of the medieval philosophers we have mentioned.

What methodology should philosophers follow? Should they rely on methods that can be conducted from the armchair? Or should they leave the armchair and turn to the methods of the natural sciences, such as experiments in the laboratory? Or is this opposition itself a false one? Arguments about philosophical methodology are raging in the wake of a number of often conflicting currents, such as the growth of experimental philosophy, the resurgence of interest in metaphysical questions, and the use of formal (...) methods. This outstanding collection of specially-commissioned chapters by leading international philosophers discusses these questions and many more. It provides a comprehensive survey of philosophical methodology in the most important philosophical subjects: metaphysics, epistemology, philosophy of language, philosophy of mind, phenomenology, philosophy of science, ethics, and aesthetics. A key feature of the collection is that philosophers discuss and evaluate contrasting approaches in each subject, offering a superb overview of the variety of methodological approaches - both naturalistic and non-naturalistic - in each of these areas. They examine important topics at the heart of methodological argument, including the role of intuitions and conceptual analysis, thought experiments, introspection, and the place that results from the natural sciences should have in philosophical theorizing. The collection begins with a fascinating exchange about philosophical naturalism between Timothy Williamson and Alexander Rosenberg, and also includes contributions from the following philosophers: Lynne Rudder Baker, Matt Bedke, Greg Currie, Michael Devitt, Matthew C. Haug, Jenann Ismael, Hilary Kornblith, Neil Levy, E.J. Lowe, Kirk Ludwig, Marie McGinn, David Papineau, Matthew Ratcliffe, Georges Rey, Jeffrey W. Roland, Barry C. Smith, Amie L.

© 2015, Springer-Verlag Berlin Heidelberg.Genetic studies have identified single nucleotide polymorphisms associated with the risk of prostate cancer. It remains unclear whether such genetic variants are associated with disease aggressiveness. The NCI-SPORE Genetics Working Group retrospectively collected clinicopathologic information and genotype data for 36 SNPs which at the time had been validated to be associated with PC risk from 25,674 cases with PC. Cases were grouped according to race, Gleason score and aggressiveness. Statistical analyses were used to compare the frequency (...) of the SNPs between different disease cohorts. After adjusting for multiple testing, only PC-risk SNP rs2735839 was significantly and inversely associated with aggressive and high-grade disease in European men. Similar associations with aggressive and high-grade disease were documented in African-American subjects. The G allele of rs2735839 was associated with disease aggressiveness even at low PSA levels in both European and African-American men. Our results provide further support that a PC-risk SNP rs2735839 near the KLK3 gene on chromosome 19q13 may be associated with aggressive and high-grade PC. Future prospectively designed, case-case GWAS are needed to identify additional SNPs associated with PC aggressiveness. (shrink)

A probability distribution is regular if no possible event is assigned probability zero. While some hold that probabilities should always be regular, three counter-arguments have been posed based on examples where, if regularity holds, then perfectly similar events must have different probabilities. Howson (2017) and Benci et al. (2016) have raised technical objections to these symmetry arguments, but we see here that their objections fail. Howson says that Williamson’s (2007) “isomorphic” events are not in fact isomorphic, but Howson is speaking (...) of set-theoretic representations of events in a probability model. While those sets are not isomorphic, Williamson’s physical events are, in the relevant sense. Benci et al. claim that all three arguments rest on a conflation of different models, but they do not. They are founded on the premise that similar events should have the same probability in the same model, or in one case, on the assumption that a single rotation-invariant distribution is possible. Having failed to refute the symmetry arguments on such technical grounds, one could deny their implicit premises, which is a heavy cost, or adopt varying degrees of instrumentalism or pluralism about regularity, but that would not serve the project of accurately modelling chances.

Of course there is a long history of such sayings in all the world’s main spiritual traditions. Socrates’ remark reminds us at once of Solon’s doleful doctrine that we should call no man happy until he is dead (Herodotus Histories Book 1; Aristotle Nicomachean Ethics 1100a11). And Bonhoeffer’s famous saying, while it echoes the typical teaching of many Christian spiritual masters, for instance St Thomas à Kempis and Bianco da Siena (the author of that beautiful hymn “Come down O Love (...) Divine”), is ultimately just a paraphrase of Jesus’ even more famous saying that anyone who wants to follow him must “deny himself, and take up his cross, and follow me” (Matthew 16.24). (shrink)

In his short review of The Political Philosophy of Herbert Spencer , Timothy Virkkala (May 1999) praises Tim S. Gray's discussion of the great classical liberal's methodology as a synthesis of "individualist" and "holist" approaches to social theory. But Virkkala remarks This method -I'm tempted to call it "dialectical," but Spencer's prose and position seem so far from Hegel's that the term is almost indecent -confuses many readers. But it is surely his strength. Gray is one of the few (...) Spencer scholars to see this method as fundamental, and to present sophisticated analyses of Spencer's syntheses. It is unfortunate that Virkkala refuses to give into his temptation, because crucially significant aspects of Herbert Spencer's work are, indeed, dialectical. (shrink)

The mathematician William Kingdon CliTord (1845–1879) is generally remembered as a potentially great man whose life was cut short before his genius was fully realized. During his lifetime CliTord was well known in London as a public intellectual and noted authority on science. He was also an iconoclast, a leader in the application of Darwinian principles to areas beyond biology, and a proponent of non-Euclidean geometry. Unlike other agnostics, CliTord did not mourn the loss of his religious belief, nor did he worry that a secularized society would bring about general social decay. While other scientiWc naturalists worried that a collapse of religion would destroy morality and lead to social disintegration, CliTord willingly ceded the universal truths religion oTered, embracing the uncertainty that scientiWc knowledge actually entailed. He even dared to call himself an atheist. However, CliTord’s death at age 34 curtailed the trace of his thought. What remains is consigned to his scant private notebooks and collected works. Perhaps it was the brevity of his life that has led to his neglect within the history of science; no comprehensive appraisal of his mathematical work has been written. CliTord’sbest-knownnon-mathematical statementisthat“itiswrongalways, everywhere, and for anyone, to believe anything upon insuUcient evidence.” This was the statement he defended in his lecture “The Ethics of Beliefz”, which he delivered to London’s Metaphysical Society in 1876. The Metaphysical Society, founded in 1869 to promote discussion between religious believers and scientiWc rationalists, ceased operation in 1880 after members could not Wnd enough common ground to begin debate. The rationalist position CliTord argues in “The Ethics of Beliefz” stands on the far side of the spectrum within this discourse. CliTord’s immoderate stance, along with his use of biblical rhetoric to argue a secularist position, was calculated to provoke conservative intellectuals and institutions.1 When his essay appeared in the January 1877 issue April 3, 2010 (11:17 am) C:\Users\Milt\Desktop\backup copy of Ken's G\WPData\TYPE2902\russell 29,2 050 red.wpd Reviews 189 of Contemporary Review, it proved antagonistic enough that it led in part to the dismissal of James Knowles as editor. Timothy Madigan’s book W.yK. CliVord and “The Ethics of Beliefz”z provides an introduction to and analysis of CliTord’s ethical philosophy. His goal is to outline the historical context from which CliTord’s most famous essay arose, and to analyze the merits and demerits of its argument through the viewpoints of critics and freethinkers from the nineteenth century to the present. Madigan gives a brief history of the Victorian crisis of faith, CliTord’s mathematical work, and the biographical details of his life. He presents the argument CliTord makes within “The Ethics of Beliefz”, and outlines the critical response from his contemporaries, including founding members of the Metaphysical Society William George Ward and Richard H. Hutton, poet Matthew Arnold, physiologist George John Romanes, and American psychologist and philosopher William James. Madigan also discusses the positions argued by other rationalists in the 1870s,1880sandlater(Leslie Stephen, Karl Pearson, FriedrichNietzsche, Charles Peirce and Bertrand Russell) and by modern philosophers who have contributed to the rationalist/religionist debate (C.yS. Lewis, J.yL. Mackie, Michael Martin, Peter van Inwagen, Susan Haack, Anthony Quinton, and Lorraine Code). In Chapter 6 Madigan presents his own defence of CliTord’s ethics of belief. While early sections of the book provide a helpful summary of previously published work, I found Madigan’s discussion of CliTord’s writings on psychology and theory of mind particularly valuable (pp. 58–65). Madigan notes positively that CliTord’s contribution helped steer the early development... (shrink)

Timothy Williamson gives an original and provocative treatment of deep metaphysical questions about existence, contingency, and change, using the latest resources of quantified modal logic. Contrary to the widespread assumption that logic and metaphysics are disjoint, he argues that modal logic provides a structural core for metaphysics.

At any given time, a subject has a multiplicity of conscious experiences. A subject might simultaneously have visual experiences of a red book and a green tree, auditory experiences of birds singing, bodily sensations of a faint hunger and a sharp pain in the shoulder, the emotional experience of a certain melancholy, while having a stream of conscious thoughts about the nature of reality. These experiences are distinct from each other: a subject could experience the red book without the singing (...) birds, and could experience the singing birds without the red book. But at the same time, the experiences seem to be tied together in a deep way. They seem to be unified, by being aspects of a single encompassing state of consciousness. (shrink)

Matthew Soteriou provides an original philosophical account of sensory and cognitive aspects of consciousness.

This book addresses a range of relevant theoretical issues, including the possibility of an interpersonally comparable measure of well-being, or “utility” metric; the moral value of equality, and how that bears on the form of the social welfare function; social choice under uncertainty; and the possibility of integrating considerations of individual choice and responsibility into the social-welfare-function framework. This book also deals with issues of implementation, and explores how survey data and other sources of evidence might be used to calibrate (...) both a utility metric and a social welfare function, and whether distributive goals are ever best pursued through regulation rather than the tax system. In working through this range of theoretical and practical issues, the book draws from a wide variety of literatures, including philosophical scholarship on equality, responsibility, the nature of well-being, and personal identity over time; the social choice literature within economics; applied economic literatures concerning the measurement of inequality and poverty; legal and policy-analysis scholarship on cost-benefit analysis, environmental justice, and the choice between regulation and taxation; and the burgeoning field of “happiness studies”.

No existing normative decision theory adequately handles risk. Expected Utility Theory is overly restrictive in prohibiting a range of reasonable preferences. And theories designed to accommodate such preferences (for example, Buchak's (2013) Risk‐Weighted Expected Utility Theory) violate the Betweenness axiom, which requires that you are indifferent to randomizing over two options between which you are already indifferent. Betweenness has been overlooked by philosophers, and we argue that it is a compelling normative constraint. Furthermore, neither Expected nor Risk‐Weighted Expected Utility Theory (...) allow for stakes‐sensitive risk‐attitudes—they require that risk matters in the same way whether you are gambling for loose change or millions of dollars. We provide a novel normative interpretation of Weighted‐Linear Utility Theory that solves all of these problems. (shrink)

This paper attempts to show how Adorno’s thought can illuminate our reflections on the future of work. It does so by situating Adorno’s conception of genuine activity in relation to his negativist critical epistemology and his subtle account of the distinction between true and false needs. What emerges is an understanding of work that can guide our aspirations for the future of work, and one we illustrate via discussions of creative work and care work. These are types of work which (...) cater to persistent human needs, albeit ones that are distorted under present social conditions. Adorno’s thought helps us to understand why this is the case.

This work presents a historically informed, systematic exposition of the Christology of the first seven Ecumenical Councils of undivided Christendom, from the First Council of Nicaea in 325 AD to the Second Council of Nicaea in 787 AD. Assuming the truth of Conciliar Christology for the sake of argument, Timothy Pawl considers whether there are good philosophical arguments that show a contradiction or incoherence in that doctrine. He presents the definitions of important terms in the debate and a helpful (...) metaphysics for understanding the incarnation. -/- In Defense of Conciliar Christology discusses three types of philosophical objections to Conciliar Christology. Firstly, it highlights the fundamental philosophical problem facing Christology: how can one thing be both God and man, when anything deserving to be called "God" must have certain attributes, and yet it seems that nothing that can aptly be called "man" can have those same attributes? It then considers the argument that if the Second Person of the Holy Trinity were immutable or atemporal, as Conciliar Christology requires, then that Person could not become anything, and thus could not become man. Finally, Pawl addresses the objection that if there is a single Christ then there is a single nature or will in Christ. However, if that conditional is true, then Conciliar Christology is false, since it affirms the antecedent of the conditional to be true, but denies the truth of the consequent. Pawl defends Conciliar Christology against these charges, arguing that all three philosophical objections fail to show Conciliar Christology inconsistent or incoherent. (shrink)

This paper addresses the nature of sensed-presence experiences that are commonplace among the bereaved and occur cross-culturally. Although these experiences are often labelled ‘‘bereavement hallucinations’’, it is unclear what they consist of. Some seem to involve sensory experiences in one or more modalities, while others involve a non-specificfeelingorsenseof presence. I focus on a puzzle concerning the latter: it is unclear how an experience of someone’s presence could arise without a more specific sensory content. I suggest that at least some of (...) these experiences consist in a dynamic and non-localized experience of significant and salientpossibilities. This can amount to the sense of currentlyrelating toa particular individual and, by implication, a sense of that person’s presence. Where an experience of this kind also includes sensory qualities, they are inessential to the sense of relatedness and perhaps symptomatic of it. (shrink)

Ideal theory has been extensively contested on the grounds that it is ideology: namely, that it performs the distorting social role of reifying and enforcing unjust features of the status quo. Indeed, a growing number of philosophers adopt a nonideal methodology—which dispenses with ideal theory—because of this ideology critique. I argue, however, that such philosophers are confused about the ultimate dialectical upshot of this critique even if it succeeds. I do so by constructing a parallel—equally plausible—ideology critique of nonideal methodology; (...) specifically, I argue that capitalist and managerial social attitudes have commodified people’s conception of justice and induced suspicion of ideal theory, which is not construed as having direct practical value. Consequently, nonideal methodology performs the distorting role of reifying and enforcing the hegemonies of capitalism and managerialism. Ideal theory and nonideal methodology are, therefore, in symmetrically bad positions. (shrink)

Vetter (2015) develops a localised theory of modality, based on potentialities of actual objects. Two factors play a key role in its appeal: its commitment to Hardcore Actualism, and to Naturalism. Vetter’s commitment to Naturalism is in part manifested in her adoption of Aristotelian universals. In this paper, we argue that a puzzle concerning the identity of unmanifested potentialities cannot be solved with an Aristotelian conception of properties. After introducing the puzzle, we examine Vetter’s attempt at amending the Aristotelian conception (...) in a way that avoids the puzzle, and conclude that this amended version is no longer to be considered naturalistic. Potentiality theory cannot be both actualist and naturalist. We then argue that, if naturalism is to be abandoned by the actualist, there are good reasons to adopt a Platonist conception of universals, for they offer a number of theoretical advantages and allow us to avoid some of the problems facing Vetter’s theory.

Should we remain neutral between our interests and those of future generations? Or are we ethically permitted or even required to depart from neutrality and engage in some measure of intergenerational discounting? This Article addresses the problem of intergenerational discounting by drawing on two different intellectual traditions: the social welfare function (“SWF”) tradition in welfare economics, and scholarship on “prioritarianism” in moral philosophy. Unlike utilitarians, prioritarians are sensitive to the distribution of well-being. They give greater weight to well-being changes affecting (...) worse-off individuals. Prioritarianism can be captured, formally, through an SWF which sums a concave transformation of individual utility, rather than simply summing unweighted utilities in utilitarian fashion. The Article considers the appropriate structure of a prioritarian SWF in intergenerational cases. The simplest case involves a fixed and finite intertemporal population. In that case, I argue, policymakers can and should maintain full neutrality between present and future generations. No discount factor should be attached to the utility of future individuals. Neutrality becomes trickier when we depart from this simple case, meaning: (1) “non-identity” problems, where current choices change the identity of future individuals; (2) population-size variation, where current choices affect not merely the identity of future individuals, but the size of the world’s future population (this case raises the specter of what Derek Parfit terms “the repugnant conclusion,” i.e., that dramatic reductions in the average level of individual well-being might be compensated for by increases in population size); or (3) an infinite population. The Article grapples with the difficult question of outfitting a prioritarian SWF to handle non-identity problems, population-size variation, and infinite populations. It tentatively suggests that a measure of neutrality can be maintained even in these cases. (shrink)
