There is a high prevalence of comorbidity between neurodevelopmental disorders. Contemporary research of these comorbidities has led to the development of multifactorial theories of causation, including the multiple deficit model. While several combinations of disorders have been investigated, the nature of association between literacy and motor disorders remains poorly understood. Comorbid literacy and motor disorders were the focus of the two present studies. In Study 1, we examined the prevalence of comorbid literacy and motor difficulties relative to isolated literacy and (...) motor difficulties in a community sample. The prevalence of comorbidity was five times greater than expected by chance alone, implying some relationship between difficulties. In Study 2, we examined the cognitive profiles of children with literacy and motor disorders amongst a subsample of children from Study 1. Children with literacy disorder had deficits in phonological processing, selective attention, and memory whilst children with motor disorder had deficits in visuospatial processing and memory, suggesting the disorders should be considered to have both independent and shared cognitive risk factors. Children with comorbid literacy and motor disorder demonstrated an additive combination of these deficits. Together, these findings are consistent with predictions from the MDM. (shrink)

I address an intuition commonly endorsed by metaphysicians, that there must be a fundamental layer of reality, i.e., that chains of ontological dependence must terminate: there cannot be turtles all the way down. I discuss applications of this intuition with reference to Bradley’s regress, composition, realism about the mental and the cosmological argument. I discuss some arguments for the intui- tion, but argue that they are unconvincing. I conclude by making some suggestions for how the intuition should be argued for, (...) and discussing the ramifications of giving the justification I think best. (shrink)

In order to prevent the rapid spread of COVID-19, governments have placed significant restrictions on liberty, including preventing all non-essential travel. These restrictions were justified on the basis the health system may be overwhelmed by COVID-19 cases and in order to prevent deaths. Governments are now considering how they may de-escalate these restrictions. This article argues that an appropriate approach may be to lift the general lockdown but implement selective isolation of the elderly. While this discriminates against the elderly, there (...) is a morally relevant difference—the elderly are far more likely to require hospitalisation and die than the rest of the population. If the aim is to ensure the health system is not overwhelmed and to reduce the death rate, preventing the elderly from contracting the virus may be an effective means of achieving this. The alternative is to continue to keep everyone in lockdown. It is argued that this is levelling down equality and is unethical. It suggests that in order for the elderly to avoid contracting the virus, the whole population should have their liberty deprived, even though the same result could be achieved by only restricting the liberty of the elderly. Similar arguments may also be applied to all groups at increased risk of COVID-19, such as men and those with comorbidities, the obese and people from ethnic minorities or socially deprived groups. This utilitarian concern must be balanced against other considerations, such as equality and justice, and the benefits gained from discriminating in these ways must be proportionately greater than the negative consequences of doing so. Such selective discrimination will be most justified when the liberty restriction to a group promotes the well-being of that group (apart from its wider social benefits). (shrink)

The World is Born From Zero is an investigation into the relationship between video games and science fiction through the philosophy of speculation. Cameron Kunzelman argues that the video game medium is centered on the evaluation and production of possible futures by following video game studies, media philosophy, and science fiction studies to their furthest reaches. Claiming that the best way to understand games is through rigorous formal analysis of their aesthetic strategies and the cultural context those strategies emerge (...) from, Kunzelman investigates a diverse array of games like The Last of Us, VA-11 Hall-A, and Civilization VI in order to explore what science fiction video games can tell us about their genres, their ways of speculating, and how the medium of the video game does (or does not) direct us down experiential pathways that are both oppressive and liberatory. Taking a multidisciplinary look at these games, The World is Born From Zero offers a unique theorization of science fiction games that provides both science fiction studies and video game studies with new tools for thinking how this medium and mode inform each other.

I argue that the truthmaker theorist should be a priority monist if she wants to avoid commitment to mysterious necessary connections. In section 1 I briefly discuss the ontological options available to the truthmaker theorist. In section 2 I develop the argument against truthmaker theory from the Humean denial of necessary connections. In section 3 I offer an account of when necessary connections are objectionable. In section 4 I use this criterion to narrow down the options from section 1. In (...) section 5 I argue that the account leads us to priority monism. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Black and White:A Note on Ancient NicknamesAlan CameronDistinguishing homonyms is a problem in any society, and it is not perhaps surprising that the same simple devices recur over long periods of time and in different parts of the ancient (and modern) world.P. Amh. LXII.6–7 lists two Ptolemaic soldiers called Apollonios, distinguishing them as μέλας and. Some years ago Frank M. Snowden suggested that the first of the pair was (...) actually black–skinned.1 A. M. Devine raised two different objections to this hypothesis.2 First, he finds "little hard evidence to suggest that general colour–terms like μέλας by themselves carried any specific racial connotations in antiquity." Yet it depends what is meant by hard evidence. There is certainly some evidence, for which reference may now be made to Lloyd A. Thompson's useful book Romans and Blacks (1989). But "racial connotations" are not really the point at issue. The question is rather, did the writer intend to indicate the color of the first Apollonios' skin?Personal descriptions in Egyptian documents do in fact very frequently specify skin color as an identifying characteristic. But they normally use a more subtle vocabulary than just black/white:.3 I do not recall seeing plain μέλας and used for this purpose. If skin color were the explanation here, we should have to assume that two men described bluntly as black and white one after another on the same document stood at opposite ends of the spectrum in skin color. That this should happen in the case of men who were in addition homonyms would surely be an improbable coincidence. The explanation must [End Page 113] lie in their homonymy. Second, Devine proposed a satisfying alternative, an exact parallel where explanation in terms of skin color is excluded: Alexander's two Macedonian marshals called Cleitus, again distinguished as μέλας and.4Devine went on to suggest that the black/white antithesis "was doubtless a commonplace... in Hellenistic armies." There is no need to restrict the practice to the military—or indeed to the Hellenistic world. I can add another three or four examples, from a much wider social, chronological, and geographical range. First another Hellenistic case. Diogenes Laertius names two Epicurean philosophers from Alexandria called Ptolemaios who were also distinguished in this way: δύο τε Πτο (10.25).5 It is suggestive that no explanation of the nicknames was felt necessary. Next an example from Ostrogothic Italy. Anicius Acilius Aginantius Faustus cos. A.D. 483 and Anicius Probus Faustus cos. 490 were distinguished as Albus and Niger respectively.6 Third, the consuls of 61 and 53 B.C., cousins who both bore the names M. Valerius Messala, were distinguished as Niger and Rufus respectively.7 Last, those who have seen the recent film Donnie Brasco may recall two capi in the Bonanno crime family, Alphonse "Sonny" Indelicato and Dominick "Sonny" Napolitano, distinguished as "Sonny Red" and "Sonny Black."8Roman cognomina were often based on physical peculiarities (Ahala, Ahenobarbus, Balbus, Cincinnatus, Crus, Dentatus, Nasica, Paetus, to quote the merest handful), and Niger and Rufus appear often enough as regular cognomina.9 The earliest Rufi were no doubt so called because of their red hair,10 but then the name was passed down to descendants regardless of hair color, as a fixed part of their nomenclature. The phenomenon under discussion is something different, perhaps picked up by the Romans from Hellenistic practice. [End Page 114]In most cases, these homonyms could have been and doubtless often were distinguished satisfactorily enough by the use of a father's name or ethnic or (for the Romans) full nomenclature. But in many contexts this must have seemed too formal. The color–nicknames were an informal device. Like (for example) νέος or iunior,11 they had the limited function of distinguishing people in a specific, often informal context. Like νέος and iunior again, they were not a formal or permanent element in a man's nomenclature and should not be so treated in modern works of reference.For example, after the death of Black Cleitus, White Cleitus was presumably known as just Cleitus. The two Fausti were by no means exact homonyms. It was only in contexts where they were styled simply... (shrink)

In two shocking articles that appeared in 1968 and 1974, Garrett Hardin argued that the population explosion was producing a “tragedy of the commons.” Since we lack an effective method of sharing common resources, the strong incentive for individuals to appropriate them selfishly would soon lead to their collapse. To mitigate this danger, Hardin proposed a “lifeboat ethic”: less populated and -polluted Western countries should deny food aid to developing nations, where it would save lives only to increase population pressure, (...) and they should close their borders to immigration to prevent their lifeboats from becoming overcrowded and going down with the rest. This paper challenges and complicates Hardin’s account of the tragedy. While there is something right about his view, its vulnerability to a series of empirical challenges reflects its conceptual limitations. I argue that we need to develop a broadly ethical and arguably religious solution to the twin challenges of population growth and pollution. If the liberal commitment to negative freedom is, ironically, largely responsible for our current ecological bind, our only hope of escape is to build bridges between traditions in search of a thicker sense of ethicopolitical obligation.

In their recent article, ‘Why lockdown of the elderly is not ageist and why levelling down equality is wrong’, Savulescu and Cameron argue for selective isolation of the elderly as an alternative to general lockdown. An important part of their argument is the claim that the latter amounts to ‘levelling down equality’ and that this is ‘unethical’ or even ‘morally repugnant’. This response argues that they fail to justify either part of this claim: the claim that levelling down is (...) always morally wrong is subject to challenges that Savulescu and Cameron do not consider; and a policy of maintaining general lockdown does not constitute levelling down, as it provides absolute benefits to those who would be worse off under selective isolation.

With increasing inoculations and emerging coronavirus variants, governments worldwide are challenged to adopt proper liberty-restricting measures to reduce the spread of COVID-19 and minimise grave consequences for liberty and well-being caused by over a year-long pandemic. Cameron et al ’s proposal of a selective strategy addresses this pressing issue.1 Following Savulescu and Cameron, they argue for limiting the liberty of the elderly. But, instead of claiming not doing so is an instance of wrongful levelling down equality, they argue (...) this discriminative strategy is morally acceptable.2 I argue against the selective liberty-restrictive measures after proposing a revision of the five-limb proportionality test that plays a pivotal role in supporting their argument. The following is a reconstruction of Cameron et al ’s central argument: It is ethically acceptable to promote the best outcome. One way to promote the best outcome is to maximise utility at the population level without imposing unreasonable costs on the most vulnerable individuals. All else being equal, adopting selective liberty-restricting measures in the COVID-19 pandemic is the best way to maximise utility at the population level without imposing unreasonable costs on the most vulnerable individuals. If it is ethically acceptable to …. (shrink)

Savulescu and Cameron supported selectively locking down the elderly during the COVID-19 pandemic on two grounds: first, that preserving total lockdown would entail levelling down and, second, that levelling down is wrong. Their first assumption has been thoroughly addressed, but more can be said about their wider antiegalitarian point that levelling down is simply wrong. Egalitarians are not defenceless against the levelling-down objection. Even though some consider it the most serious challenge to supporters of equality, egalitarianism possesses sound reasons (...) to assert, not only that something valuable is preserved when we level down, but also that preserving it may be, in certain circumstances, preferable to pursuing other fundamental moral goals. Although troublesome from a well-being maximising standpoint, levelling down ensures that healthcare policy reflects a commitment with the idea that people are equal in moral worth. That commitment is important enough to trump certain improvements in individual well-being. In the case of pandemic lockdowns, not all the interests protected by free movement are as fundamental as to pursue them at the cost of equality. Savulescu and Cameron’s framework is so reliant on the view that levelling down is wrong that it fails to account for the valuable loss that having the elderly suffer alone represents. (shrink)

In a recent article, ‘Why lockdown of the elderly is not ageist and why levelling down equality is wrong’, Savulescu and Cameron argue that a selective lockdown of older people is not ageist because it would treat people unequally based on morally relevant differences.

Locke’s metaphysical commitments are a matter of some controversy. Further controversy attends the issue of whether and how Locke adapts his views in order to accommodate the success of Newton’s Principia. The chapter lays out an interpretation of Locke’s commitments according to which Locke’s response to Newton on gravity does not require the positing of brute powers and is consistent with his core essentialism. The chapter raises the question of how the hypothesis concerning the creation of matter, alluded to at (...) 4.10.18, fits with these commitments. The chapter concludes that the De grav hypothesis would represent a significant revision to the background metaphysical picture of the Essay, but that nevertheless its attractions to Locke are intelligible and illuminating.

Both Immanuel Kant and Paul Guyer have raised important concerns about the limitations of Lockean thought. Following Guyer, I will focus my attention on questions about the proper ambitions and likely achievements of inquiry into the natural/physical world. I will argue that there are at least two important respects, not discussed by Guyer, in which Locke’s account of natural philosophy is much more flexible and accommodating than may be immediately apparent. On my interpretation, however, one crucial source of a too-limited (...) vision of natural philosophy remains in Locke, where he is appropriately criticized by both Kant and Guyer. My method will be to begin with a distinction that Locke draws in the very first draft of the Essay, between what he calls “the sensible object” and, on the other hand, “the uncertain philosophical cause.” I believe that Locke’s notion of “sensible object,” as opposed to uncertain philosophical cause, retains a central place in his thought in the published Essay, despite the fact thateven though this contrast is never made explicitly there. Tracing the evolution of these two concepts in his thought will allow us to track and better understand his developing views about the relation between the project of the. (shrink)

In their recent paper ‘Why lockdown of the elderly is not ageist and why levelling down equality is wrong’ Savulescu and Cameron attempt to argue the case for subjecting the ‘elderly’ to limits not imposed on other generations. We argue that selective lockdown of the elderly is unnecessary and cruel, as well as discriminatory, and that this group may suffer more than others in similar circumstances. Further, it constitutes an unjustifiable deprivation of liberty.

Are philosophers of history—or, are some philosophers of history—sufficiently interested in questions of the details of historical research? This is intended as a real as well as a rhetorical question. I may simply have failed to find discussions that are available; but in the material I have been able to consider there is little treatment of matters of preliminary detail, and this seems to me a neglect that needs to be remedied.

This article explores the way in which death metaphors written in the urban mural for David Bowie in London contribute to creatively reframing the artist’s death. While research on death metaphors has focussed on traditional written genres such as obituaries and epitaphs, studies of urban memorials and shrines have focussed on the creation of fandom identities, downplaying the role played by figurativity, creativity and emotional connotation. The present article aims to bridge the gap between these two areas of study by (...) presenting a corpus-based study of 585 items written on the mural for David Bowie. The research questions are: How is Bowie’s death conceptualised? To what extent are death metaphors in Bowie’s mural creative? and What is the relationship between the metaphorical framing of Bowie’s death and the projection of emotional connotations? The findings of our study reveal that Bowie’s songs emerge as a highly productive metaphorical source domain to understand the artist’s death, in which fans recontextualise lines from Bowie’s lyrics in creative and positive ways.

I explore Locke’s complex attitude toward the natural philosophy of his day by focusing on Locke’s own treatment of Newton’s theory of gravity and the presence of Lockean themes in defenses of Newtonian attraction/gravity by Maupertuis and other early Newtonians.

This study examined the influence of integrative motivation, instrumental motivation and second language (L2) proficiency on socio-cultural/academic adaptation in a sample of two groups of international students studying Chinese in China. Results revealed that the non-Asian student group reported higher levels of integrative motivation, socio-cultural adaptation and Chinese language proficiency than the Asian student group, who reported a higher level of instrumental motivation. No significant difference was found in academic adaptation between the two groups. Moreover, the relationships between study variables (...) are the same across Asian and non-Asian student groups. Further evidence from this research indicated that socio-cultural adaptation was influenced more by integrative motivation and less by L2 proficiency. Integrative motivation was found to be the only significant predictor of academic adaptation. Implications for future research are discussed. (shrink)

One of the deepest tensions in Locke’s Essay, a work full of profound and productive conflicts, is one between Locke’s metaphysical tendencies—his inclination to presuppose or even to argue for substantive metaphysical positions—and his devout epistemic modesty, which seems to urge agnosticism about major metaphysical issues. Both tendencies are deeply rooted in the Essay. Locke is a theorist of substance, essence, quality. Yet, his favorite conclusions are epistemically pessimistic, even skeptical; when it comes to questions about how the world is (...) constituted, our understandings cannot penetrate very far. Locke seems torn between metaphysics and modesty, between dogmatism and skepticism. This chapter will consider two specific examples of this sort of tension. The first involves the ontology of body, and the second, the ontology of mind. The conflict concerning bodily natures looks like this: As is well-known, Locke typically describes bodies in the terms of the corpuscularian science of his day, as exemplified especially by the natural philosopher Robert Boyle. Locke’s characterizations of the real essences of bodies are mechanist. He envisions them as corpuscularian textures-- spatial arrangements of particles possessing size. (shrink)

George Berkeley, Bishop of Cloyne, was one of the great philosophers of the early modern period. He was a brilliant critic of his predecessors, particularly Descartes, Malebranche, and Locke. He was a talented metaphysician famous for defending idealism, that is, the view that reality consists exclusively of minds and their ideas. Berkeley's system, while it strikes many as counter intuitive, is strong and flexible enough to counter most objections. His most studied works, the Treatise Concerning the Principles of Human Knowledge (...) Principles, for short) and Three Dialogues between Hylas and Philonous Dialogues), are beautifully written and dense with the sort of arguments that delight contemporary philosophers. He was also a wide ranging thinker with interests in religion (which were fundamental to his philosophical motivations), the psychology of vision, mathematics, physics, morals, economics, and medicine. Although many of Berkeley's first readers greeted him with incomprehension, he influenced both Hume and Kant, and is much read (if little followed) in our own day. (shrink)

I. Introduction Siris, Berkeley's last major work, is undeniably a rather odd book. It could hardly be otherwise, given Berkeley's aims in writing it, which are three-fold: 'to communicate to the public the salutary virtues of tar-water,'1 to provide scientific background supporting the efficacy of tar-water as a medicine, and to lead the mind of the reader, via gradual steps, toward contemplation of God.2 The latter two aims shape Berkeley's extensive use of contemporary natural science in Siris. In particular, Berkeley's (...) focus on what he calls fire (or aether or light) as a quasiuniversal 'cause' of natural change3 serves these purposes, for the 'activity' of the aether, in his view, can both explain the miraculous virtues of a certain medicine, i.e. tar-water, and reveal God's action and his divine order.4 Berkeley's corpuscular speculations, including his use of fire-theory, are not especially idiosyncratic as natural philosophy. In his theorizing, as Jessop and other have noted, he is heavily indebted to the work of Hermann Boerhaave, the Dutch chemist, botanist, and physician whose teachings were highly influential in mid-eighteenth century Britain.5 Boerhaave, along with other Dutch natural philosophers cited by Berkeley, assigned a central role in accounting for physio-chemical activity to fire, a subtle, insensible particulate substance, sometimes identified with light.

Nearly a half-century later, this student of Lieberman’s met another church historian, Virginia Burrus, in Morningside Heights under happier circumstances, when both of us were participants at a conference on asceticism at Union Theological Seminary, and a similar intellectual interaction began. This paper represents some of the first fruits of that second encounter and aspires to modestly continue the enterprise begun by the first.[2] Intertextuality and InterdisciplinarityAveril Cameron has recently written:The myth of early Christianity as the resort of the poor and underprivileged is precisely that, and a very convenient one it has been. It is a myth that rests, moreover, on the fallacy of an original Christianity uncontaminated by external influences; but its holders then have to explain how this “new” faith could make [End Page 52] the leap to center stage. Thus, we have been told, “the naiveté of the early Christian speech came in the course of time to wed itself to the cultures of the world.” But while much of current New Testament scholarship is directed at the internal (that is, theological) articulation of the texts, there is also a perceptible trend towards a mode of interpretation that balances the external and internal factors operative in the literary texts. It is thus less a question of the degree of “influence” of Greco-Roman or Jewish literary or philosophical elements on early Christian writing than of their integral relationship.[37–38]Judaism also (and Jewish scholarship) has had a stake in inscribing itself as pure and uncontaminated, for reasons that Philip Alexander has articulated: “The attempt to [lay down a norm for Judaism in the first century] barely conceals apologetic motives—in the case of Christianity a desire to prove that Christianity transcended or transformed Judaism, in the case of Jews a desire to suggest that Christianity was an alien form of Judaism which deviated from the true path” [3]. Indeed, the very distinctness of Judaism has been articulated by Jews as precisely its distance from a “syncretistic” Christianity whose defining feature is that it is somehow a composite of Judaism and Hellenism. 2In this essay, in conversation with some of the work of Burrus, I wish to begin to suggest a few of the ways that study of the Talmud can be further enriched through the engagement of talmudic scholars with the recent sophisticated (and especially gender-oriented) work being done on early Christianity. Indeed, I will be hinting (and in future work explicitly arguing) that we have to begin seriously thinking about Judaeo-Christianity as a single cultural system: contentious, dialectical, polemical, and sometimes friendly, but—I hasten to add—not moralistic in the homogenized “family values” sense implied by the modern usage of this term. I put forth here, as a case in point, that the richest contexts for understanding the sets of cultural tensions that gave rise to a particular talmudic text are to be uncovered in contemporary patristic literature. From the point of view of a New Historicist approach to talmudic literature, this suggests that the... (shrink)

Descartes and Boyle were the most influential proponents of strict mechanist accounts of the physical world, accounts which carried with them a distinction between primary and secondary (or sensible) qualities. For both, the distinction is a piece of natural philosophy. Nevertheless the distinction is quite differently articulated, and, especially, differently grounded in the two thinkers. For Descartes, reasoned reflection reveals to us that bodies must consist in mere extension and its modifications, and that sensible qualities as we conceive of them (...) based on sense perception can pertain only to the mind. Just how we are supposed to arrive at this realization is, this essay will argue, a deep puzzle that brings us to the basic assumptions of Descartes' metaphysics. For Boyle, by contrast, while reflection can reveal the unique explanatory status of mechanism, and, thus, the primary/secondary quality distinction, only experience can confirm its truth. Our central focus will be on Descartes, and on the question: How does he intend to remove the sensible qualities from the physical world, how does he strip them from bodies? I will try to show that Descartes has an argument that he takes to show a priori that sensible qualities cannot be attributed to the material world (as foundational qualities, or, as we conceive of them based on sense experience). The argument fails, however, leaving him with at best a partly empirical case for removing the sensible qualities, based on the purported explanatory success of his physics. (shrink)

Although George Berkeley himself made no major scientific discoveries, nor formulated any novel theories, he was nonetheless actively concerned with the rapidly evolving science of the early eighteenth century. Berkeley's works display his keen interest in natural philosophy and mathematics from his earliest writings (Arithmetica, 1707) to his latest (Siris, 1744). Moreover, much of his philosophy is fundamentally shaped by his engagement with the science of his time. In Berkeley's best-known philosophical works, the Principles and Dialogues, he sets up his (...) idealistic system in opposition to the materialist mechanism he finds in Descartes and Locke. In De Motu, Berkeley refines and extends his philosophy of science in the context of a critique of the dynamic accounts of motion offered by Newton and Leibniz. And in Siris, Berkeley's flirtation with neo-Platonism draws inspiration from the fire theory of Boerhaave as well as Newton's aetherial speculations in the Queries of the Optics. In examining Berkeley's critical engagement with the natural philosophy of his time, we will thus improve our understanding of not just his philosophy of science, but of his philosophical corpus as a whole.

While De Motu, Berkeley's treatise on the philosophical foundations of mechanics, has frequently been cited for the surprisingly modern ring of certain of its passages, it has not often been taken as seriously as Berkeley hoped it would be. Even A.A. Luce, in his editor's introduction to De Motu, describes it as a modest work, of limited scope. Luce writes: The De Motu is written in good, correct Latin, but in construction and balance the workmanship falls below Berkeley's usual standards. (...) The title is ambitious for so brief a tract, and may lead the reader to expect a more sustained argument than he will find. A more modest title, say Motion without Matter, would fitly describe its scope and content. Regarded as a treatise on motion in general, it is a slight and disappointing work; but viewed from a narrower angle, it is of absorbing interest and high importance. It is the application of immaterialism to contemporary problems of motion, and should be read as such. ...apart from the Principles the De Motu would be nonsense.1.. (shrink)

Pierre Louis Moreau de Maupertuis’ famous and influential Discours sur les différentes figures des astres, which represented the first public defense of attractionism in the Cartesian stronghold of the Paris Academy, sometimes suggests a metaphysically agnostic defense of gravity as simply a regularity. However, Maupertuis’ considered account in the essay, I argue, is much more subtle. I analyze Maupertuis’ position, showing how it is generated by an extended consideration of the possibility of attraction as an inherent property and fuelled by (...) an understanding of Lockean skepticism about knowledge of real essences that is more nuanced perhaps even than Locke’s own.
