Background: Freezing of gait is a common symptom in Parkinson’s disease and can be difficult to treat with dopaminergic medications or with deep brain stimulation. Novel stimulation paradigms have been proposed to address suboptimal responses to conventional DBS programming methods. Burst-cycling deep brain stimulation delivers current in various frequencies of bursts, while maintaining an intra-burst frequency identical to conventional DBS.Objective: To evaluate the safety and tolerability of BCDBS in PD patients with FOG.Methods: Ten PD subjects with STN or GPi DBS (...) and complaints of FOG were recruited for this single center, single blinded within-subject crossover study. For each subject, we compared 4, 10, and 15 Hz BCDBS to conventional DBS during the PD medication-OFF state.Results: There were no serious adverse events with BCDBS. It was feasible and straightforward to program BCDBS in the clinic setting. The benefit was comparable to conventional DBS in measures of FOG, functional mobility and in PD motor symptoms. BCDBS had lower battery consumption when compared to conventional DBS.Conclusions: BCDBS was feasible, safe and well tolerated and it has potential to be a viable future DBS programming strategy.

René Girard, Theology, and Pop Culture provides a fresh and engaging introduction to and the application of René Girard's mimetic theory. From movies to social media, television to graphic novels, the contributors explore popular culture's theological depths and challenge readers to consider what culture reveals about them.

Michael Ryan (d. 1840) remains one of the most mysterious figures in the history of medical ethics, despite the fact that he was the only British physician during the middle years of the 19th century to write about ethics in a systematic way. Michael Ryan’s Writings on Medical Ethics offers both an annotated reprint of his key ethical writings, and an extensive introductory essay that fills in many previously unknown details of Ryan’s life, analyzes the significance of (...) his ethical works, and places him within the historical trajectory of the field of medical ethics.

Ryan Recalls is not a typical autobiography for while it contains personal memoirs and preoccupations, it also contains book reviews, book launches, published and unpublished papers as well as various newspaper articles put together by the author" --Page 2 of cover.

Ted Warfield has argued that if Ockhamism and Molinism offer different responses to the problems of foreknowledge and prophecy, it is the Molinist who is in trouble. I show here that this is not so – indeed, things may be quite the reverse.

In this original and rewarding combination of intellectual and political history, Ryan Balot offers a thorough historical and sociological interpretation of classical Athens centered on the notion of greed. Integrating ancient philosophy, poetry, and history, and drawing on modern political thought, the author demonstrates that the Athenian discourse on greed was an essential component of Greek social development and political history. Over time, the Athenians developed sophisticated psychological and political accounts of acquisitiveness and a correspondingly rich vocabulary to describe (...) and condemn it. Greed figures repeatedly as an object of criticism in authors as diverse as Solon, Thucydides, and Plato--all of whom addressed the social disruptions caused by it, as well as the inadequacy of lives focused on it. Because of its ethical significance, greed surfaced frequently in theoretical debates about democracy and oligarchy. Ultimately, critiques of greed--particularly the charge that it is unjust--were built into the robust accounts of justice formulated by many philosophers, including Plato and Aristotle. Such critiques of greed both reflected and were inextricably knitted into economic history and political events, including the coups of 411 and 404 B.C. Balot contrasts ancient Greek thought on distributive justice with later Western traditions, with implications for political and economic history well beyond the classical period. Because the belief that greed is good holds a dominant position in modern justifications of capitalism, this study provides a deep historical context within which such justifications can be reexamined and, perhaps, found wanting.

AI and people do not compete on a level-playing field. Self-driving vehicles may be safer than human drivers, but laws often penalize such technology. People may provide superior customer service, but businesses are automating to reduce their taxes. AI may innovate more effectively, but an antiquated legal framework constrains inventive AI. In The Reasonable Robot, Ryan Abbott argues that the law should not discriminate between AI and human behavior and proposes a new legal principle that will ultimately improve human (...) well-being. This work should be read by anyone interested in the rapidly evolving relationship between AI and the law. (shrink)

Ryan Wasserman explores a range of fascinating puzzles raised by the possibility of time travel, with entertaining examples from physics, science fiction, and popular culture, and he draws out their implications for our understanding of time, tense, freedom, fatalism, causation, counterfactuals, laws of nature, persistence, change, and mereology.

This book explores the constraints which justice imposes on immigration policy. Like liberal nationalists, Ryan Pevnick argues that citizens have special claims to the institutions of their states. However, the source of these special claims is located in the citizenry's ownership of state institutions rather than in a shared national identity. Citizens contribute to the construction and maintenance of institutions, and as a result they have special claims to these institutions and a limited right to exclude outsiders. Pevnick shows (...) that the resulting view justifies a set of policies - including support for certain types of guest worker programs - which is distinct from those supported by either liberal nationalists or advocates of open borders. His book provides a framework for considering a number of connected topics including issues related to self-determination, the scope of distributive justice and the significance of shared national identity.

John Stuart Mill is—surprisingly—a difficult writer. He writes clearly, non-technically, and in a very plain prose which Bertrand Russell once described as a model for philosophers. It is never hard to see what the general drift of the argument is, and never hard to see which side he is on. He is, none the less, a difficult writer because his clarity hides complicated arguments and assumptions which often take a good deal of unpicking. And when we have done that unpicking, (...) the task of analysing the merits and deficiencies of the arguments is still only half completed. This is true of all his work and particularly true of Liberty. It is an essay whose clarity and energy have made it the most popular of all Mill's work. Yet it conceals philosophical, sociological and historical assumptions of a very debatable kind. In his introduction, Mill says the object of this essay is to defend one very simple principle, as entitled to govern absolutely the dealings of society with the individual in the way of compulsion and control, whether the means used be legal penalties, or the moral coercion of public opinion.

This paper is a small contribution to two large subjects. The first large subject is that of exploitation—what it is for somebody to be exploited, in what ways people can be and are exploited, whether exploitation necessarily involves coercion, what Marx's understanding of exploitation was and whether it was adequate: all these are issues on which I merely touch, at best. My particular concern here is to answer the two questions, whether Marx thought capitalist exploitation unjust and how the answer (...) to that question illuminates Marx's conception of morality in general. The second large subject is that of the nature of morality—whether there are specifically moral values and specifically moral forms of evaluation and criticism, how these relate to our explanatory interests in the same phenomena, what it would be like to abandon the ‘moral point of view’, whether the growth of a scientific understanding of society and ourselves inevitably undermines our confidence in the existence of moral ‘truths’. These again are issues on which I only touch if I mention them at all, but the questions I try to answer are, what does Marx propose to put in the place of moral judgment, and what kind of assessment of the horrors of capitalism does he provide if not a moral assessment?

In his late work Religion within the Boundaries of Mere Reason, Immanuel Kant struggles to answer a straightforward, yet surprisingly difficult, question: how is radical conversion--a complete reorientation of a person's most deeply held values--possible? In this book, Ryan S. Kemp and Christopher Iacovetti examine how this question gets taken up by Kant's philosophical heirs: Schelling, Fichte, Hegel and Kierkegaard. More than simply developing a novel account of each thinker's position, Kemp and Iacovetti trace how each philosopher formulates his (...) theory in response to tensions in preceding views, culminating in Kierkegaard's claim that radical conversion lies outside a person's control. Kemp and Iacovetti close by examining some of the moral-psychological implications of Kierkegaard's account, particularly the question of how someone might responsibly relate to values that have, by their own admission, been acquired in contingent and accidental fashion.

Very diverse societies pose real problems for Rawlsian models of public reason. This is for two reasons: first, public reason is unable accommodate diverse perspectives in determining a regulative ideal. Second, regulative ideals are unable to respond to social change. While models based on public reason focus on the justification of principles, this book suggests that we need to orient our normative theories more toward discovery and experimentation. The book develops a unique approach to social contract theory that focuses on (...) diverse perspectives. It offers a new moral stance that author Ryan Muldoon calls, "The View From Everywhere," which allows for substantive, fundamental moral disagreement. This stance is used to develop a bargaining model in which agents can cooperate despite seeing different perspectives. Rather than arguing for an ideal contract or particular principles of justice, Muldoon outlines a procedure for iterated revisions to the rules of a social contract. It expands Mill's conception of experiments in living to help form a foundational principle for social contract theory. By embracing this kind of experimentation, we move away from a conception of justice as an end state, and toward a conception of justice as a trajectory. (shrink)

From an evolutionary standpoint, a default presumption is that true beliefs are adaptive and misbeliefs maladaptive. But if humans are biologically engineered to appraise the world accurately and to form true beliefs, how are we to explain the routine exceptions to this rule? How can we account for mistaken beliefs, bizarre delusions, and instances of self-deception? We explore this question in some detail. We begin by articulating a distinction between two general types of misbelief: those resulting from a breakdown in (...) the normal functioning of the belief formation system (e.g., delusions) and those arising in the normal course of that system's operations (e.g., beliefs based on incomplete or inaccurate information). The former are instances of biological dysfunction or pathology, reflecting limitations of evolutionary design. Although the latter category includes undesirable (but tolerable) by-products of limited design, our quarry is a contentious subclass of this category: misbeliefs best conceived as design features. Such misbeliefs, unlike occasional lucky falsehoods, would have been systematically adaptive in the evolutionary past. Such misbeliefs, furthermore, would not be reducible to judicious action policies. Finally, such misbeliefs would have been adaptive in themselves, constituting more than mere by-products of adaptively biased misbelief-producing systems. We explore a range of potential candidates for evolved misbelief, and conclude that, of those surveyed, only positive illusions meet our criteria. (shrink)

This paper focuses on a recently articulated, emergentist conception of ethical naturalism and its commitment to causal efficacy, or the idea that moral properties have causal powers, along with its supporting commitment to moral causation. After I reconstruct the theory, I explain how it offers some interesting theoretical benefits to moral realists in virtue of its commitment to causal efficacy. Then, after locating some examples of moral causation in support of this commitment, I present and respond to five objections to (...) such causation, which all threaten to undermine this support. Lastly, I consider a very serious problem that the theory faces in virtue of positing emergent moral properties as responsible for moral causation – namely, the problem of downward moral causation. I describe this problem in detail and argue that, as it stands, it does not spell doom for the theory. (shrink)

Many have argued that early visual processing is encapsulated from the influence of higher-level goals, expectations, and knowledge of the world. Here we confront the main arguments offered in support of such a view, showing that they are unpersuasive. We also present evidence of top–down influences on early vision, emphasizing data from cognitive neuroscience. Our conclusion is that encapsulation is not a defining feature of visual processing. But we take this conclusion to be quite modest in scope, readily incorporated into (...) mainstream vision science. (shrink)

In this article, robust evidence is provided showing that an individual’s moral character can contribute to the aesthetic quality of their appearance, as well as being beautiful or ugly itself. It is argued that this evidence supports two main conclusions. First, moral beauty and ugliness reside on the inside, and beauty and ugliness are not perception-dependent as a result; and, second, aesthetic perception is affected by moral information, and thus moral beauty and ugliness are on the outside as well.

I argue that the main existing accounts of the relationship between the beauty of environmental entities and their moral standing are mistaken in important ways. Beauty does not, as has been suggested by optimists, confer intrinsic moral standing. Nor is it the case, as has been suggested by pessimists, that beauty at best provides an anthropocentric source of moral standing that is commensurate with other sources of pleasure. I present arguments and evidence that show that the appreciation of beauty tends (...) to cause a transformational state of mind that is more valuable than mere pleasure, but that leads us to falsely represent beautiful entities as being sentient and, in turn, as having intrinsic moral standing. To this extent, beauty is not, then, a source of intrinsic moral standing; it’s a source of a more important anthropocentric value than has hitherto been acknowledged. (shrink)

Scientific research is almost always conducted by communities of scientists of varying size and complexity. Such communities are effective, in part, because they divide their cognitive labor: not every scientist works on the same project. Philip Kitcher and Michael Strevens have pioneered efforts to understand this division of cognitive labor by proposing models of how scientists make decisions about which project to work on. For such models to be useful, they must be simple enough for us to understand their dynamics, (...) but faithful enough to reality that we can use them to analyze real scientific communities. To satisfy the first requirement, we must employ idealizations to simplify the model. The second requirement demands that these idealizations not be so extreme that we lose the ability to describe real-world phenomena. This paper investigates the status of the assumptions that Kitcher and Strevens make in their models, by first inquiring whether they are reasonable representations of reality, and then by checking the models' robustness against weakenings of these assumptions. To do this, we first argue against the reality of the assumptions, and then develop a series of agent-based simulations to systematically test their effects on model outcomes. We find that the models are not robust against weakenings of these idealizations. In fact we find that under certain conditions, this can lead to the model predicting outcomes that are qualitatively opposite of the original model outcomes. (shrink)

A common view holds that consciousness is needed for knowledge acquired in one domain to be applied in a novel domain. We present evidence for the opposite; where the transfer of knowledge is achieved only in the absence of conscious awareness. Knowledge of artificial grammars was examined where training and testing occurred in different vocabularies or modalities. In all conditions grammaticality judgments attributed to random selection showed above-chance accuracy , while those attributed to conscious decisions did not. Participants also rated (...) each string’s familiarity and performed a perceptual task assessing fluency. Familiarity was predicted by repetition structure and was thus related to grammaticality. Fluency, though increasing familiarity, was unrelated to grammaticality. While familiarity predicted all judgments only those attributed to random selection showed a significant additional contribution of grammaticality, deriving primarily from chunk novelty. In knowledge transfer, as in visual perception , the unconscious may outperform the conscious. (shrink)

Deep brain stimulation is an experimental procedure for treatment-resistant depression. Some results show promise, but blinded trials had limited success. Ethical questions center on vulnerability: especially on whether depressed patients can weigh the risks and benefits effectively, whether depression causes “desperation,” and whether media portrayals create unrealistic hopes. We interviewed 24 psychiatric inpatients with treatment-resistant depression, qualitatively analyzing their comments. Most had minimal interest in deep brain stimulators. Some might consider them if their depression worsened, if alternatives were exhausted, or (...) if the evidence were stronger. Fears focused on the surgery, adverse effects, and the novelty of the device. Patients felt the depression interfered with their ability to weigh the risks and benefits. Patients seemed highly attuned to the risks, and were skeptical that the treatment would be effective. We conclude that ethical concerns about vulnerability remain, yet patients with treatment-resistant depression were thoughtful and cautious about trying a novel therapy. (shrink)

What role should the physician's conscience play in the practice of medicine? Much controversy has surrounded the question, yet little attention has been paid to the possibility that disputants are operating with contrasting definitions of the conscience. To illustrate this divergence, we contrast definitions stemming from Abrahamic religions and those stemming from secular moral tradition. Clear differences emerge regarding what the term conscience conveys, how the conscience should be informed, and what the consequences are for violating one's conscience. Importantly, these (...) basic disagreements underlie current controversies regarding the role of the clinician's conscience in the practice of medicine. Consequently participants in ongoing debates would do well to specify their definitions of the conscience and the reasons for and implications of those definitions. This specification would allow participants to advance a more philosophically and theologically robust conversation about the means and ends of medicine. (shrink)

Effective Altruism is a rapidly growing and influential contemporary philosophical movement committed to updating utilitarianism in both theory and practice. The movement focuses on identifying urgent but neglected causes and inspiring supererogatory giving to meet the need. It also tries to build a broader coalition by adopting a more ecumenical approach to ethics which recognizes a wide range of values and moral constraints. These interesting developments distinguish Effective Altruism from the utilitarianism of the past in ways that invite cooperation and (...) warrant a fresh look from Thomists. Nonetheless Effective Altruism’s fundamentally consequentialist and aggregative model for ethics precludes more foundational agreement with Thomistic ethics in ways that limit the extent of practical cooperation.

For Heidegger, phenomenological investigation is carried out by formal indication, the name given to the methodical approach he assumes in Being and Time. This paper attempts to draw attention to the nature of formal indication in light of the fact that it has been largely lost upon American scholarship (mainly due to its inconsistent translation). The roots of the concept of formal indication are shown in two ways. First, its thematic treatment in Heidegger's 1921/22 Winter Semester course, Phenomenological Investigations into (...) Aristotle, is examined to make clear what Heidegger silently assumes in Being and Time. Second, Heidegger's adaptation of Husserl's use of the term, indication, is outlined to clarify the concept even more. The enhanced understanding of formal indication granted by these two points leads to a better grasp of Heidegger's concept of truth, for formal indication and truth are mutually implied for Heidegger. Finally, it is suggested that the reader of Being and Time, on the basis of what formal indication demands, approach the work not as a doctrine to be learned but as a task always requiring further completion.

Which traits are beautiful? And is their beauty perceptual? It is argued that moral virtues are partly beautiful to the extent that they tend to give rise to a certain emotion— ecstasy—and that compassion tends to be more beautiful than fair-mindedness because it tends to give rise to this emotion to a greater extent. It is then argued, on the basis that emotions are best thought of as a special, evaluative, kind of perception, that this argument suggests that moral virtues (...) are partly beautiful to the extent that they tend to give rise to a certain kind of evaluative perceptual experience.

DNA sequencers, Twitter, MRIs, Facebook, particle accelerators, Google Books, radio telescopes, Tumblr: what do these things have in common? According to the evangelists of “data science,” all of these are instruments for observing reality at unprecedentedly large scales and fine granularities. This perspective ignores the social reality of these very different technological systems, ignoring how they are made, how they work, and what they mean in favor of an exclusive focus on what they generate: Big Data. But no data, big (...) or small, can be interpreted without an understanding of the process that generated them. Statistical data science is applicable to systems that have been designed as scientific instruments, but is likely to lead to confusion when applied to systems that have not. In those cases, a historical inquiry is preferable. (shrink)

Business and Economic textbooks warn against committing the Sunk Cost Fallacy: you, rationally, shouldn't let unrecoverable costs influence your current decisions. In this paper, I argue that this isn't, in general, correct. Sometimes it's perfectly reasonable to wish to carry on with a project because of the resources you've already sunk into it. The reason? Given that we're social creatures, it's not unreasonable to care about wanting to act in such a way so that a plausible story can be told (...) about you according to which your diachronic behavior doesn't reveal that you've suffered, what I will call, diachronic misfortune. Acting so as to hide that you've suffered diachronic misfortune involves striving to make yourself easily understood while disguising any shortcomings that might damage your reputation as a desirable teammate. And making yourself easily understood to others while hiding your flaws will, sometimes, put pressure on you to honor sunk costs. (shrink)

I offer the first sustained defence of the claim that ugliness is constituted by the disposition to disgust. I advance three main lines of argument in support of this thesis. First, ugliness and disgustingness tend to lie in the same kinds of things and properties (the argument from ostensions). Second, the thesis is better placed than all existing accounts to accommodate the following facts: ugliness is narrowly and systematically distributed in a heterogenous set of things, ugliness is sometimes enjoyed, and (...) ugliness sits opposed to beauty across a neutral midpoint (the argument from proposed intensions). And third, ugliness and disgustingness function in the same way in both giving rise to representations of contamination (the argument from the law of contagion). In making these arguments, I show why prominent objections to the thesis do not succeed, cast light on some of the artistic functions of ugliness, and, in addition, demonstrate why a dispositional account of disgustingness is correct, and present a novel problem for warrant-based accounts of disgustingness (the ‘too many reasons’ problem).

Invaluable wisdom on living a good life from the founder of modern economics Adam Smith is best known today as the founder of modern economics, but he was also an uncommonly brilliant philosopher who was especially interested in the perennial question of how to live a good life. Our Great Purpose is a short and illuminating guide to Smith's incomparable wisdom on how to live well, written by one of today's leading Smith scholars. In this inspiring and entertaining book, (...) class='Hi'>Ryan Patrick Hanley describes Smith's vision of "the excellent and praiseworthy character," and draws on the philosopher's writings to show how each of us can go about developing one. For Smith, an excellent character is distinguished by qualities such as prudence, self-command, justice, and benevolence—virtues that have been extolled since antiquity. Yet Smith wrote not for the ancient polis but for the world of market society—our world—which rewards self-interest more than virtue. Hanley shows how Smith set forth a vision of the worthy life that is uniquely suited to us today. Full of invaluable insights on topics ranging from happiness and moderation to love and friendship, Our Great Purpose enables modern readers to see Smith in an entirely new light—and along the way, learn what it truly means to live a good life.

Sharon Ryan (2000) argues against one epistemic closure principle but defends another one.

I suggest a revision to the closure principle to make it immune to this sort of counter-example.

The defetishization thesis claims alternative markets can lead to a more honest, less mystified relationship with food production and, in turn, strengthen civil society. Drawing from Marxian political economic and environmental sociological theory, I make three general claims: capitalism is inherently ecologically and socially harmful; “ethical” commodities derived from alternative markets cannot fundamentally counteract the pervasiveness and scale of ; and, because of and, ethical consumerism does not defetishize the commodity form, but acts as a new layer of commodity fetishism (...) that masks the harms of capitalism by convincing society that the harms of capitalism can be rehabilitated with the commodity form itself. Prescriptively, I argue traditional, large-scale political tactics would be needed for “defetishization” to take place. (shrink)

Let’s say that you regard two things as on a par when you don’t prefer one to other and aren’t indifferent between them. What does rationality require of you when choosing between risky options whose outcomes you regard as on a par? According to Prospectism, you are required to choose the option with the best prospects, where an option’s prospects is a probability-distribution over its potential outcomes. In this paper, I argue that Prospectism violates a dominance principle—which I call The (...) Principle of Predominance—because it sometimes requires you to do something that’s no better than the alternatives and might be worse. I argue that this undermines the strongest argument that’s been given in favor of Prospectism. (shrink)

This article looks at Colossians 2-3:17 and John 17:13-26 as the base texts to see the commonalities between Johannine and Pauline conceptions of Theosis. First, the article looks at indwelling and participation as the methods of Theosis in the two traditions. Second, the role of mimesis is seen to be integral in these texts' concepts of Theosis. Third, the article looks at hope and glory that believers have and look forward to as indicative of their deification. The study begins by (...) defining the term Theosis and its cognate terms - deification and divinisation - properly, within an Orthodox Christian context. CONTRIBUTION: The goal is to see and detail the concept of Theosis in Pauline and Johannine literature, looking at Colossians 2-3:17 and John 17:13-26 specifically. As such, the present study will broaden the discussion the doctrine of Theosis as it appears in the Christian scriptures. (shrink)
