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.

One of the most important recent developments in the discussion of Kierkegaard's ethics is an interpretation defended, in different forms, by Philip Quinn and Stephen Evans. Both argue that a divine-command theory of moral obligation is to be found in Works of Love . Against this view, I argue that, despite significant overlap between DCT and the view of moral obligation found in Works of Love , there is at least one essential difference between the two: the former, but not (...) the latter, is committed to the claim that, necessarily, p is morally obligatory only if God commands that p.

Frank Jackson has given us an elegant and important book. It is, by a long shot, the most sophisticated defense of the use of conceptual analysis in philosophy that has ever been offered. But we also we find it a rather perplexing book, for we can’t quite figure out what Jackson thinks a conceptual analysis is. And until we get clearer on that, we’re not at all sure that conceptual analysis, as Jackson envisions it, is possible. The (...) main reason for our perplexity is that Jackson seems to be making some empirical assumptions about people’s intuitions and the psychological mechanisms that give rise to them, though it is far from clear exactly what these empirical assumptions are. Moreover, on what is perhaps the most natural reading, he is making at least one assumption about which many cognitive scientists who study concepts have serious doubts. In the first of our two sections, we will elaborate this theme. Our goal, in that section, is not so much to criticize as to seek clarification. It is a great virtue of this journal’s multiple review format that critics can pose questions to authors, and the authors get to reply. So we hope that in his reply Jackson will help us understand his defense of conceptual analysis by explaining more clearly what his empirical assumptions are; and if he is indeed making an assumption that many cognitive scientists would challenge, we hope he will tell us why he thinks that challenge is misguided. In the second section, our stance will be more critical. There is one empirical assumption about which Jackson is admirably clear and explicit. However, we think there is now good reason to think that this assumption is false. (shrink)

Doxastic normativism is the thesis that norms are constitutive of or essential to belief, such that no mental state not subject to those norms counts as a belief. A common normativist view is that belief is essentially governed by a norm of truth. According to Krister Bykvist and Anandi Hattiangadi, truth norms for belief cannot be formulated without unpalatable consequences: they are either false or they impose unsatisfiable requirements on believers. I propose that we construe the fundamental norm of belief (...) as a knowledge norm, rather than a truth norm. I argue that a specific kind of knowledge norm—one that has a subject's obligation to believe that p depend on her being in a position to know that p—might avoid the well-known formulation problems with truth norms.

Paul Griffiths and John Matthewson argue that selected effects play the key role in determining whether a state is pathological. In response, it is argued that a selected effects account faces a number of difficulties in light of modern genomic research. Firstly, a modern history approach to selection is problematic as a basis for assigning function to human traits in light of the small population sizes in the hominin lineage, which imply that selection has played a limited role in shaping (...) these genomes in the evolutionarily recent past. Secondly, determining both the genetic basis of disease and selective histories of the various alleles involved may be experimentally intractable. Thirdly, the existence of “selected disorders” is well supported, and yet on the other hand many other common diseases may not reduce evolutionary fitness. In summary, the biological ends promoted by natural selection, as best modeled in recent research, do not adequately ground a concept of dysfunction that aligns well with the interests of human health.

We make a huge variety of claims framed in vocabularies drawn from physics and chemistry, everyday talk, neuroscience, ethics, mathematics, semantics, folk and professional psychology, and so on and so forth. We say, for example, that Jones feels cold, that Carlton might win, that there are quarks, that murder is wrong, that there are four fundamental forces, and that a certain level of neurological activity is necessary for thought. If we follow Huw Price's Carnapian lead, we can put this by (...) saying that we make many claims in many different frameworks. (shrink)

We investigate the causal uncertainty surrounding the flash crash in the U.S. Treasury bond market on October 15, 2014, and the unresolved concern that no clear link has been identified between the start of the flash crash at 9:33 and the opening of the U.S. equity market at 9:30. We consider the contributory effect of mini flash crashes in equity markets, and find that the number of equity mini flash crashes in the three-minute window between market open and the Treasury (...) Flash Crash was 2.6 times larger than the number experienced in any other three-minute window in the prior ten weekdays. We argue that (a) this statistically significant finding suggests that mini flash crashes in equity markets both predicted and contributed to the October 2014 U.S. Treasury Bond Flash Crash, and (b) mini-flash crashes are important phenomena with negative externalities that deserve much greater scholarly attention.

Recently, Christine Bratu and Mortiz Dittmeyer have argued that Christine Korsgaard’s constitutive project fails to establish the normativity of practical principles because it fails to show why a principle’s being constitutive of a practice shows that one ought to conform to that principle. They argue that in many cases a principle’s being constitutive of a practice has no bearing on whether one ought to conform to it. In this paper I argue that Bratu and Dittmeyer’s argument fails in three important (...) respects. First, they fail to recognize the ways in which Korsgaard’s neo-Kantian view departs from more orthodox Kantian views. Second, they fail to recognize the respect in which Korsgaard’s view is a version of moral rationalism. Third, they overlook an important scope ambiguity in an important premise of their argument. A sensible way of resolving this ambiguity gives the constitutivist a reasonable response. (shrink)

Arguments from Silence have been used many times in attempts to discredit the foundations of religions. In this project, I demonstrate how one might judge the epistemic value of such arguments. To begin, I lay out for examination a specific argument from silence given by Walter Richard Cassels in his work Supernatural Religion. I then discuss a recently developed Bayesian approach for dealing with arguments from silence. Finally, using Cassels’s work and the work of some of the critics who replied (...) to his argument, I argue for what probabilities might be applied in the use of the Bayesian method for testing the epistemic value Cassels’s argument and demonstrate how one might respond to similar arguments.

The literature on blame is rather unfriendly to views that might be characterized as “character-evaluation” accounts. Here I will defend one such account against the many objections that are leveled against it. Defending the view against these objections will help us to evaluate what such a view has to offer. This paper defends the view against objections that accounts such as this cannot account for how much we care about blame, for the distinctively human nature of the blame phenomenon, for (...) forgiving the unrepentant, and for recalcitrant blame. Responding to these objections on behalf of the much beleaguered character-evaluation account clears the way for it to stand as a serious competitor in how we understand blame. (shrink)

A semantic theory aims to make predictions that are accurate and comprehensive. Sometimes, though, a semantic theory falls short of this aim, and there is a mismatch between prediction and data. In such cases, defenders of the semantic theory often attempt to rescue it by appealing to Gricean pragmatics. The hope is that we can rescue the theory as long as we can use pragmatics to explain away its predictive failures. This pragmatic rescue strategy is one of the most popular (...) moves in philosophy of language, philosophical logic, and formal semantics. In this paper I argue that this strategy fails whenever the predictive failures at issue can be recast in epistemological or metaphysical terms. This general “reformulation argument” undermines a wide variety of pragmatic rescue attempts. (shrink)

Frank Jackson often writes as if his descriptivist account of public language meanings were just plain common sense. How else are we to explain how different speakers manage to communicate using a public language? And how else can we explain how individuals arrive at confident judgments about the reference of their words in hypothetical scenarios? Our aim in this paper is to show just how controversial the psychological assumptions behind in Jackson’s semantic theory really are. First, we explain (...) how Jackson’s theory goes well beyond the commonsense platitudes he cites in its defence. Second, we sketch an alternative explanation of those platitudes, the jazz model of meaning, which we argue is more psychologically realistic. We conclude that the psychological picture presupposed by Jackson’s semantic theory stands in need of a much more substantial defence than he has so far offered. (shrink)

Markosian presents an argument against certain theories of time based on the aesthetic value of music. He argues that turning a piece of music sideways in time destroys its intrinsic value, which would not be possible if the Spacetime Thesis were true. In this paper I show that sideways music poses no problems for any theory of time by demonstrating that turning a piece of music sideways does not affect its intrinsic value. I do this by appealing to spatial analogies (...) that highlight the similarities between spatial and temporal rotations. (shrink)

This study tested four theoretical models of leadership with data from the ethnographic record. The first was a game-theoretical model of leadership in collective actions, in which followers prefer and reward a leader who monitors and sanctions free-riders as group size increases. The second was the dominance model, in which dominant leaders threaten followers with physical or social harm. The third, the prestige model, suggests leaders with valued skills and expertise are chosen by followers who strive to emulate them. The (...) fourth proposes that in small-scale, kin-based societies, men with high neural capital are best able to achieve and maintain positions of social influence (e.g., as headmen) and thereby often become polygynous and have more offspring than other men, which positively selects for greater neural capital. Using multiple search strategies we identified more than 1000 texts relevant to leadership in the Probability Sample of 60 cultures from the Human Relations Area Files (HRAF). We operationalized the model with variables and then coded all retrieved text records on the presence or absence of evidence for each of these 24 variables. We found mixed support for the collective action model, broad support for components of the prestige leadership style and the importance of neural capital and polygyny among leaders, but more limited support for the dominance leadership style. We found little evidence, however, of emulation of, or prestige-biased learning toward, leaders. We found that improving collective actions, having expertise, providing counsel, and being respected, having high neural capital, and being polygynous are common properties of leaders, which warrants a synthesis of the collective action, prestige, and neural capital and reproductive skew models. We sketch one such synthesis involving high-quality decision-making and other computational services. (shrink)

Individualist normative theories appear inadequate for the complex moral challenges of climate change. In climate ethics, this is especially notable with the relative marginalization of Kant. I argue that Kant’s philosophy, understood through its historical and cosmopolitan dimensions, has untapped potential for the climate crisis. First, I situate Kant in climate ethics and evaluate his marginalization due to perceived individualism, interiority and anthropocentrism. Then, I explore aspects of Kant’s historical and cosmopolitan writings, which present a global, future-orientated picture of humanity. (...) Ultimately, Kant’s philosophy offers a unique take on the climate deadlock capable of sustaining the individual in the collective. (shrink)

For decades, scholars in the social sciences and humanities have questioned the appropriateness and utility of prior review of their research by human subjects' ethics committees. This essay seeks to organize thematically some of their published complaints and to serve as a brief restatement of the major critiques of ethics review. In particular, it argues that 1) ethics committees impose silly restrictions, 2) ethics review is a solution in search of a problem, 3) ethics committees lack expertise, 4) ethics committees (...) apply inappropriate principles, 5) ethics review harms the innocent, and 6) better options exist.

The contours of sustainable systems are defined according to communities’ goals and values. As researchers shift from sustainability-in-the-abstract to sustainability-as-a-concrete-research-challenge, democratic deliberation is essential for ensuring that communities determine what systems ought to be sustained. Discourse analysis of dialogue with Michigan direct marketing farmers suggests eight sustainability values – economic efficiency, community connectedness, stewardship, justice, ecologism, self-reliance, preservationism and health – which informed the practices of these farmers. Whereas common heuristics of sustainability suggest values can be pursued harmoniously, we discuss (...) how this typology reflects the more intricate project of balancing values in tension with one another.

Much work in the philosophy of religion has been devoted to exploring the virtue of faith. Very little of it, however, has done so from the perspective of Christian worship and liturgical practice. In this essay, I explore the virtue of faith, articulated in a traditionally Catholic manner, as it is practiced, engaged, and deepened through participation in the Eucharist. I begin by emphasizing both the cognitive and the volitional dimensions of a robust conception of the virtue of faith and (...) then show how devout Eucharistic practice confirms and strengthens them, affording believers a unique opportunity to deepen their belief and concretely strengthen their trust in God. I conclude by noting how a Eucharistic approach to faith can avoid a common criticism—that faith is exceedingly passive—and also help us to understand why faith and religious practice can so easily become stagnant.

Normativists about belief hold that belief formation is essentially rule- or norm-guided. On this view, certain norms are constitutive of or essential to belief in such a way that no mental state not guided by those norms counts as a belief, properly construed. In recent influential work, Kathrin Glüer and Åsa Wikforss develop novel arguments against normativism. According to their regress of motivations argument, not all belief formation can be rule- or norm-guided, on pain of a vicious infinite regress. I (...) argue that the regress of motivations argument is unsuccessful: an appeal to the notion of blind rule-following, drawn from a plausible interpretation of Ludwig Wittgenstein’s remarks on rule-following, stops the regress of motivations in its tracks.

Orthodoxy holds that there is a determinate fact of the matter about every arithmetical claim. Little argument has been supplied in favour of orthodoxy, and work of Field, Warren and Waxman, and others suggests that the presumption in its favour is unjustified. This paper supports orthodoxy by establishing the determinacy of arithmetic in a well-motivated modal plural logic. Recasting this result in higher-order logic reveals that even the nominalist who thinks that there are only finitely many things should think that (...) there is some sense in which arithmetic is true and determinate.

Theology and the University in Nineteenth-Century Germany examines the dual transformation of institutions and ideas that led to the emergence of theology as science, the paradigmatic project of modern theology associated with Friedrich Schleiermacher. Beginning with earlier educational reforms across central Europe and especially following the upheavals of the Napoleonic period, an impressive list of provocateurs, iconoclasts, and guardians of the old faith all confronted the nature of the university, the organization of knowledge, and the unity of theology's various parts, (...) quandaries which together bore the collective name of 'theological encyclopedia'. Schleiermacher's remarkably influential programme pioneered the structure and content of the theological curriculum and laid the groundwork for theology's historicization. Zachary Purvis offers a comprehensive investigation of Schleiermacher's programme through the era's two predominant schools: speculative theology and mediating theology. Purvis highlights that the endeavour ultimately collapsed in the context of Wilhelmine Germany and the Weimar Republic, beset by the rise of religious studies, radical disciplinary specialization, a crisis of historicism, and the attacks of dialectical theology. In short, the project represented university theology par excellence. Engaging in detail with these developments, Purvis weaves the story of modern university theology into the broader tapestry of German and European intellectual culture, with periodic comparisons to other national contexts. In doing so, he Purvis presents a substantially new way to understand the relationship between theology and the university, both in nineteenth-century Germany and, indeed, beyond. (shrink)

In this paper I argue that Kant’s pre-critical ontology, though generally dismissed by environmental philosophers, provides ecological lessons by way of its metaphysical affinities with environmental philosophy. First, I reference where environmental philosophy tends to place Kant and highlight his relative marginalization. This marginalization makes sense given focus on his critical works. I then outline Kant’s pre-critical ontological framework and characterize the ways in which it is ecological. Finally, I conclude with some ecological reflections on the pre-critical philosophy and its (...) possible relevance for contemporary environmental issues. (shrink)

A large body of research has indicated international students in the United States and abroad experience difficulties understanding what academic integrity is and how to avoid academic misconduct, 159–172 2011; Brown & Howell, 2001; Gullifer and Tyson Studies in Higher Education, 39, 1202-1218 2014). While most studies focus on academic misconduct and academic corruption in research ethics, 339-358 2014), this study analyzes the length, English-language readability, and translation of academic integrity policies of 453 four-year U.S. institutions of higher education. Findings (...) indicate average academic integrity policies are over 2000 words long, are written above the 16th-grade reading level, and are very rarely translated into a language other than English. In addition, no institutions published their academic integrity policies in full on their institutional international student website, possibly rendering the policy difficult to locate on the institution’s website for international students. Implications for research, policy, and practice are addressed. (shrink)

This paper reports on a study of crowd-sourcing ‘study aid’ web platforms. Students are sharing completed academic coursework through a growing network of ‘study aid’ web platforms like CourseHero.com. These websites facilitate the crowd-sourced exchange of coursework, and effectively support plagiarism. However, virtually no data exists concerning the scope or extent of coursework being shared through these platforms. This paper reports on two experiments to monitor the frequency of coursework from a sample university uploaded onto CourseHero.com. Ultimately, both experiments failed (...) to produce a clear or meaningful measurement of coursework upload frequency. The apparently widespread use of these crowd-sourcing ‘study aid’ websites and the failure of these experiments demonstrates the need for further investigation into how much coursework is being shared through such platforms, how frequently it is shared, and what kind of coursework is being shared. Addressing these issues is an important step into measuring the impact of these wellsprings of academically dishonest behavior. (shrink)

I investigate the meaning and significance of Spinoza’s elusive concept of “expression”. I do so by situating expression among his canonical relations of conception, causation, and inherence. I argue that, for Spinoza, expression necessarily corresponds to what is sufficient for conception, but implies neither causation nor inherence. This correspondence with sufficient conditions on conception and the pulling apart of expression from causation and inherence has important consequences for our grasp of the interconnections among Spinoza’s key metaphysical relations. But it also (...) has profound implications for our understanding of the essential structure of Spinoza’s ontology itself, and for the proper assessment of his rationalism. I explore these consequences by explicating Spinoza’s assertion that substance and each of its attributes are “conceived through themselves”, and by demonstrating that, on his view, the relation of conception is not to be accounted for in causal terms. A systematic treatment of the expression relation sheds new light on these issues. The result is a view of the underpinnings of Spinoza’s metaphysics that is as surprising as it is compelling.

The notion of an extended simple region (henceforth ESR) has recently been marshalled in the service of arguments for a variety of conclusions. Exactly how to understand the idea of extendedness as it applies to simple regions, however, has been largely ignored, or, perhaps better, assumed. In this paper we first (§1) outline what we take to be the standard way that philosophers are thinking about extendedness, namely as an intrinsic property of regions. We then introduce an alternative picture (§2), (...) according to which extendedness is extrinsic. In §3 we argue that it matters which way of thinking about extendedness is the right one, since how ESRs behave is sensitive to what extendedness consists in, and various arguments that appeal to ESRs turn out to be unsound if extendedness is extrinsic rather than intrinsic.

Bentham was an influential thinker with an ‘essentially practical mind’. His influence on British social and political reform, however, was indirect, coming largely after his death and largely through the work of his disciples. Bentham's own attempts to put his ideas directly into practice generally had little effect. He came closest to success in the area of penal policy, winning a contract from Pitt's government in the early 1790s to build and manage a penitentiary that was to be organized on (...) the panopticon principle. Bentham saw the penitentiary as the spearhead of prison reform and as a means of effecting a change from transportation to imprisonment as a punishment for serious crime. While Bentham's use of the panopticon principle itself has attracted most attention in the literature, there was more to his scheme than this. The penitentiary proposals were worked out in great detail, they were a conscious application of his theory of punishment, and they were consistent with and an element of his all-embracing plan of social, political, and constitutional reform.

The field of `science and religion' is exploding in popularity among both academics and the reading public. This is a comprehensive and authoritative introduction to the debate, written by the leading experts yet accessible to the general reader.

Despite a strong historical record of resettling and providing care for refugee populations, the Australian Federal Government has increasingly implemented harsh and restrictive policies regarding the treatment and management of asylum seekers. Most controversial of these has been the mandatory detention of asylum seekers, a policy applied indiscriminately and without discretion where individual cases have not been subject to judicial review or time constraints. From the outset health professionals have raised concerns about the possible adverse mental health impacts of prolonged (...) detention. In contrast, government representatives have characterized conditions in detention as benign and comfortable, and have consistently contested criticism of detention, often citing a lack of scientific evidence as tacit support for the continuation of the policy. Nevertheless, requests for access to the detention centres to undertake rigorous scientific investigations have gone unheeded. In this context we argue that the Australian Government has failed to uphold its commitment to good governance by allowing transparency, openness and a willingness to have the impact of its policies scrutinized by scientists. The manifest conflict of interest in the government position leads to a breach in the normal social contract between mental health researchers and those responsible for the policy of detention. There is, we argue, a legitimate moral imperative in such situations for clinical researchers to breach the walls of enforced silence and give a voice to those who are afflicted. This imperative, however, must be carefully balanced against the risks that may face detainees agreeing to participate in such research. (shrink)
