Simulation relations have been discovered in many areas: Computer Science, philosophical and modal logic, and set theory. However, the simulation condition is strictly a first-order logic statement. We extend modal logic with modalities and axioms, the latter’s modeling conditions are the simulation conditions. The modalities are normal, i.e., commute with either conjunctions or disjunctions and preserve either Truth or Falsity (respectively). The simulations are considered arrows in a category where the objects are descriptive, general frames. One can augment the simulation (...) modalities by axioms for requiring the underlying modeling simulations to be bisimulations or to be p-morphisms. The modal systems presented are multi-sorted and both sound and complete with respect to their algebraic and Kripke semantics. (shrink)

Malebranche's Theodicy ANDREW G. BLACK LEIBNIZ'S SOLUTION tO the problem of evil, his theodicy, might be regarded as a paradigm of philosophical theology. Its pattern, as with so much of Leibniz's philosophy, is reconciliation of deep metaphysical truth with recalcitrant ap- pearance. Thus, a theodicy is not just any solution to the problem; strictly speaking it is a vindication of divine providence in the face of the challenge posed by apparent imperfections of all kinds in creation.' The preeminence (...) of Leibniz's theodicy as a modern solution to the problem of evil has helped to obscure distinguished contributions from among his contemporaries. Not least among these is that made by Nicolas Malebranche, a philosopher having much in common with Leibniz . ~ Malebranche shows a deep concern for the problem of evil throughout his philosophical writings, though nowhere more so than in his Treatise on Nature and Grace, a a book written in response to the Jansenist4 challenge to orthodox In addition to an entire and substantial book, the Theodicy , a number of Leibniz's essays contain versions of his theodicy. See, for example, articles 1- 7 of the Discourse on Metaphysics; also "A Vindication of God's Justice Reconciled with his.. (shrink)

This paper provides practitioner and academic insights into the importance of examining non-technical skills in a multiteam system emergency response. The case of public health professionals is highlighted, illustrated with unique qualitative field data which focused upon the use of non-technical skills at a meso level of analysis. Results reflected the importance of context upon the multiteam system and highlighted seven non-technical skills used by public health professionals to support an effective response. Recommendations for future research and implications for practice (...) are noted for this hard to access professional group, located within emerging advances in the scientific inquiry of complex and increasingly evident, multi-team systems.

The core dimensions of cognitive fitness, such as attention and cognitive control, are emerging through a transdisciplinary expert consensus on what has been termed the Cognitive Fitness Framework. These dimensions represent key drivers of cognitive performance under pressure across many occupations, from first responders to sport, performing arts and the military. The constructs forming the building blocks of CF2 come from the RDoC framework, an initiative of the US National Institute of Mental Health aimed at identifying the cognitive processes underlying (...) normal and abnormal behavior. Similar to physical conditioning, cognitive fitness can be improved with deliberate practice. This paper reports the development of a prototype cognitive fitness training program for competitive athletes and the protocol for its evaluation. The program is focused on primary cognitive capacities and subtending skills for adjusting training rhythms and enhancing readiness for competition. The project is driven by the Australian Psychological Society’s College of Sport & Exercise Psychology and includes the development of a Cognitive Gym program for a smartphone app-enhanced implementation. Its key building blocks are training protocols connected by a periodized training plan. A website with background supporting resources has also been developed as part of the project. National-level training squads will participate in a three-week pilot evaluation protocol, assessing the program’s efficacy and usability through gamified cognitive assessment of participants’ training gains and coaching staff evaluations, respectively. Both near and far transfer of training effects will be examined. (shrink)

Aristotle warned against a 'missing middle' in logic (Gk Mesos – middle; intermediate). This paper submits that one of the reasons why there has been no major breakthrough in macroeconomics since the financial crisis of 2007-08 has been a missing middle in mainstream micro-macro syntheses, constrained by partial and general equilibrium premises. It maintains that transcending this needs recognition that large and dominant multinational corporations between small micro firms and macro outcomes – while also influencing both – merit the conceptual (...) paradigm of mesoeconomics. Drawing on a range of uses of the concept, it relates this to reasons for 'too big to fail' and suggests implications for policies to gain accountability of big business, including how a meso dimension to input-output could yield transparency on risk-prone financial transactions by banks, and of corporations contributing to climate change. It also critiques misrepresentation of Walras and Pareto, as well as suggesting areas for research which could address, and potentially redress, 'missing middles' in mainstream micro-macro syntheses.

This paper describes a network of three interconnected, multidisciplinary research projects designed to investigate environmental health issues faced by First Nations in Canada. These projects, developed in collaboration with academia, used a participatory approach meant to build capacity, raise awareness, and initiate change. The first project, which began in British Columbia in 2008, gathered information on the traditional diet; for example, its composition, nutritional quality, and potential for chemical exposure. This 10-year, Canada-wide project served as a model for two follow-up (...) projects: one on biomonitoring and another on indoor air quality. All three projects provided community ownership over the data and communicated results in a culturally sensitive manner to encourage interest in research and initiate risk reduction activities. The Assembly of First Nations, a national advocacy organization representing over 630 First Nations communities across Canada, participated in all aspects of the research while coordinating communications and arranging timely dissemination of results. These projects showed how properly executed, community-based research can be a valuable tool for stimulating interest in scientific studies while promoting self-reliance, components often missing from academic research.

Developing countries face numerous barriers to conducting effective and efficient ethics reviews of international collaborative research. In addition to potentially overlooking important scientific and ethical considerations, inadequate or insufficiently trained ethics committees may insist on unwarranted changes to protocols that can impair a study's scientific or ethical validity. Moreover, poorly functioning review systems can impose substantial delays on the commencement of research, which needlessly undermine the development of new interventions for urgent medical needs. In response to these concerns, the Drugs (...) for Neglected Diseases Initiative, an independent nonprofit organization founded by a coalition of public sector and international organizations, developed a mechanism to facilitate more effective and efficient host country ethics review for a study of the use of fexinidazole for the treatment of late stage African Trypanosomiasis. The project involved the implementation of a novel ‘pre-review’ process of ethical oversight, conducted by an ad hoc committee of ethics committee representatives from African and European countries, in collaboration with internationally recognized scientific experts. This article examines the process and outcomes of this collaborative process. (shrink)

The evolution of complex life forms, such as multicellular organisms, is the result of a number of evolutionary transitions in individuality (ETIs). Several attempts have been made to explain their origins, many of which have been internalist (i.e., based largely on internal properties of these life form's ancestors). Here, we show how an externalist perspective, via the ecological scaffolding model in which properties of complex life forms arise from an external scaffold, can shed new light on the question of ETIs. (...) Ultimately, we anticipate progress in the field will occur by recognizing the importance of both the internalist and externalist modes of explanation for ETIs. We illustrate this by considering an extension of the ecological scaffolding model by niche construction in which particles modify the environment which later becomes the scaffold giving rise to collective-level individuality.

Progressive supranuclear palsy is a movement disorder with prominent tau neuropathology. Brain diseases with abnormal tau deposits are called tauopathies, the most common of which is Alzheimer's disease. Environmental causes of tauopathies include repetitive head trauma associated with some sports. To identify common genetic variation contributing to risk for tauopathies, we carried out a genome-wide association study of 1,114 individuals with PSP and 3,247 controls followed by a second stage in which we genotyped 1,051 cases and 3,560 controls for the (...) stage 1 SNPs that yielded P ≤ 10-3. We found significant previously unidentified signals associated with PSP risk at STX6, EIF2AK3 and MOBP. We confirmed two independent variants in MAPT affecting risk for PSP, one of which influences MAPT brain expression. The genes implicated encode proteins for vesicle-membrane fusion at the Golgi-endosomal interface, for the endoplasmic reticulum unfolded protein response and for a myelin structural component. © 2011 Nature America, Inc.

This essay, by the editor of Common Knowledge, introduces the sixth and final installment of “Fuzzy Studies,” the journal's “Symposium on the Consequence of Blur.” Suggesting that “Fuzzy Studies” should be understood in the context of a desultory campaign against zeal conducted in the journal for almost twenty years, he explains that the editors' assumption has been that any authentic case for the less adamant modes of thinking, or the less focused ways of seeing, needs to be unenthusiastic and carefully (...) ramified. To establish the distinction between overenthused and unemphatic approaches to blur, he contrasts the ecstatically amorphous “Blur building” with examples of classical Chinese landscape painting. Elizabeth Diller and Richard Scofidio, in their book blur: the making of nothing, chronicle the development of their plans for the Blur building and, in the process, inadvertently show that, to overbear various negative associations of blur and fog, the authors/architects grew self-contradictorily emphatic about the need to produce de-emphasis in architecture and in modern life. Perl shows how this self-contradiction appears also in phenomenology-inflected writings on blur by T. J. Clark, Yve-Alain Bois and Rosalind Kraus, J.-P. Sartre, and Georges Bataille, but not in the work of the phenomenologist François Jullien, whose book The Great Image Has No Form analyzes the role of blur in classical Chinese art theory and practice. Where traditional Western painting, Jullien argues, calls for voyeuristically intense focus, traditional Chinese painting stimulates “dé-tente, relaxation or ‘untensing’.” Intense focus on a blur is still, Perl observes, an intense focus. In describing a painting by the Yuan Dynasty master Ni Zan, Perl concludes that the only way to be un-self-contradictorily positive about fuzziness, whether in logic or aesthetics, is to de-reify and de-differentiate with the aim of achieving blandness.

Hawking particles emitted by a black hole are usually found to have thermal spectra, if not exactly, then by a very good approximation. Here, we argue differently. It was discovered that spherical partial waves of in-going and out-going matter can be described by unitary evolution operators independently, which allows for studies of space-time properties that were not possible before. Unitarity dictates space-time, as seen by a distant observer, to be topologically non-trivial. Consequently, Hawking particles are only locally thermal, but (...) globally not: we explain why Hawking particles emerging from one hemisphere of a black hole must be 100 % entangled with the Hawking particles emerging from the other hemisphere. This produces exclusively pure quantum states evolving in a unitary manner, and removes the interior region for the outside observer, while it still completely agrees locally with the laws of general relativity. Unitarity is a starting point; no other assumptions are made. Region I and the diametrically opposite region II of the Penrose diagram represent antipodal points in a PT or CPT relation, as was suggested before. On the horizon itself, antipodal points are identified. A candidate instanton is proposed to describe the formation and evaporation of virtual black holes of the type described here. (shrink)

In the standard formalism of quantum gravity, black holes appear to form statistical distributions of quantum states. Now, however, we can present a theory that yields pure quantum states. It shows how particles entering a black hole can generate firewalls, which however can be removed, replacing them by the ‘footprints’ they produce in the out-going particles. This procedure can preserve the quantum information stored inside and around the black hole. We then focus on a subtle but unavoidable (...) modification of the topology of the Schwarzschild metric: antipodal identification of points on the horizon. If it is true that vacuum fluctuations include virtual black holes, then the structure of space-time is radically different from what is usually thought. (shrink)

Unlike the first generation of critical theorists, contemporary critical theory has largely ignored technology. This is to the detriment of a critical theory of society – technology is now a central feature of our daily lives and integral to the contemporary form of capitalism. Rather than seek to rescue the first generation’s substantive theory of technology, which has been partly outmoded by historical developments, the approach adopted in this article is to engage with today’s technology through the conceptual apparatus offered (...) by the early Frankfurt School. This rationale is guided by the conviction that the core ideas of critical theory still offer a sound basis for assessing the nature of technology today. Through a reconstruction and engagement with some of the core concepts of first-generation critical theory, as well as the work of Bernard Stiegler and Andrew Feenberg, we can arrive at a more robust theory of technology, capable of critically interrogating the role of technology in contemporary society.

A promising strategy for better understanding space and time at the Planck scale, is outlined and further pursued. It is explained in detail, how black hole unitarity demands the existence of transformations that can remove firewalls. This must then be combined with a continuity condition on the horizon, with antipodal identification as an inevitable consequence. The antipodal identification comes with a \ inversion. We claim to have arrived at ‘new physics’, but rather than string theory, our ‘new physics’ concerns (...) new constraints on the topology and the boundary conditions of general coordinate transformations. The resulting theory is conceptually quite non trivial, and more analysis is needed. A strong entanglement between Hawking particles at opposite sides of the black hole is suspected, but questions remain. A few misconceptions concerning black holes, originating from older investigations, are discussed. (shrink)

Programmed cell death (PCD) in unicellular organisms is in some instances an altruistic trait. When the beneficiaries are clones or close kin, kin selection theory may be used to explain the evolution of the trait, and when the trait evolves in groups of distantly related individuals, group or multilevel selection theory is invoked. In mixed microbial communities, the benefits are also available to unrelated taxa. But the evolutionary ecology of PCD in communities is poorly understood. Few hypotheses have been offered (...) concerning the community role of PCD despite its far-reaching effects. The hypothesis we consider here is that PCD is a black queen. The Black Queen Hypothesis (BQH) outlines how public goods arising from a leaky function are exploited by other taxa in the community. Black Queen (BQ) traits are essential for community survival, but only some members bear the cost of possessing them, while others lose the trait In addition, BQ traits have been defined in terms of adaptive gene loss, and it is unknown whether this has occurred for PCD. Our conclusion is that PCD fulfils the two most important criteria of a BQ (leakiness and costliness), but that more empirical data are needed for assessing the remaining two criteria. In addition, we hold that for viewing PCD as a BQ, the original BQH needs to include social traits. Thus, despite some empirical and conceptual shortcomings, the BQH provides a helpful avenue for investigating PCD in microbial communities. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Editor’s IntroductionGerard A. HauserThe call for papers for this special issue of Philosophy and Rhetoric1 acknowledged the continuous centrality of human agency across the history of Western thought on rhetoric. At its ancient Greek origins, the Sophists and philosophers were at swords points over the question of what constituted responsible speech and who had responsibility for the consequences of moving the demos to public actions that bore on the (...) city-state and the lives of its citizens. On the one hand, sophistic understood the human world as indeterminate, progressing or regressing through appeals that would establish social and political reality for the community through the power of language and argument to move the minds and hearts of citizens. Protagoras expressed this vision with his aphorism, "Man is the measure of all things, of the things that are, that they are, and of the things that are not, that they are not." Central to their understanding of the human world was a recognition and exploration of language's psychogogic powers. For the philosophers, on the other hand, sophistic's position represented a problematic abandonment of the quest for Eternal Truth.The tension between the quest for contingent truth and Eternal Truth is illustrated by Xenophon's rendition of the aftermath of the Athenian naval victory at Arginoussai, in 406 BCE. In his Hellenika,2 he recounts how some of the victorious fleet's sailors became separated from it during the confusion of battle and were left behind. Although the commanders sent a group to rescue them, violent seas thwarted their efforts and the men drowned. Upon returning to Athens as victors, the commanders were arrested and charged with cowardice. The Ecclesia met to decide whether to bind them over for trial. The commanders seemed to have persuaded most of their innocence, but time ran out for that day's proceedings before a vote on whether to bind them over for a trial could be taken. That evening, at a festival in the city, opponents of the commanders attended dressed in [End Page 181] black mourning clothes and pretended to be grieving relatives of the lost sailors. Their displays of sorrow over the sailors' deaths were so convincing that they swung the emotions of many in the opposite direction.The next day, opponents of the commanders played upon the events of the night before and the citizens, remembering the displays of grief they had witnessed, were persuaded to try the commanders themselves, rather than deciding whether to bind them over to the courts for trial. Arguments went back and forth on how to interpret the tragic event—were the commanders brave but foiled by nature, or was their conduct spineless? Did they deserve a laurel wreath for their victory in battle, or to be executed for cowardice in allowing the stranded sailors to drown? Finally a vote was taken and, reversing their sentiment from the day before, the citizens voted to condemn the commanders. The military leaders were taken away to be executed. Soon thereafter, Xenophon tells us, the citizens had a change of heart and wished to reverse their verdict. However, since it was too late—the generals having already been put to death!—they lodged a complaint against those who had persuaded them to convict for "deceiving the People."The story may be read as a representative anecdote of rhetoric's fatal flaw or of rhetoric's constitutive powers of agency. On one reading, Athenian Ecclesiasts, convulsed with emotion, were stripped of their agency by arguments seeking the probable through sensory engagement structured by phantasia and mimesis3 while lacking a foundation in the Eternally True. However, it also may be read as disclosing the absence of Eternal Truth on which to ground a human world, and the agential power of language—of rhetoric—to constitute understanding and action.4 On one side, agency resided in the self-aware person who made responsible arguments with reference to pure reason and ideal justice. On the other, agency resided in the powers of language to engage thoughts and emotions, of discourse to circulate, and of representative thinking5 for discovering human reality. These latter were products of human... (shrink)

Theodor W.Adorno was one of the towering intellectuals of the twentieth century. His contributions cover such a myriad of fields, including the sociology of culture, social theory, the philosophy of music, ethics, art and aesthetics, film, ideology, the critique of modernity and musical composition, that it is difficult to assimilate the sheer range and profundity of his achievement.

Pietraszewski exemplifies the need for computational theory using group conflict; I complement this with an example of group cooperation. He criticizes past theories for having black boxes; I suggest his theory also has a black box – the concept of costs. He divides what mentally constitutes a group from mere ancillary attributes; I hazard that some of these attributes are essential.

The Flats, a district near downtown Cleveland, was once was the vibrant heart of Midwestern industry and is now in the throes of change: Some of its warehouses and factories have been transformed into nightclubs and restaurants, while homes in adjacent neighborhoods have been replaced by mini-mansions. In Cleveland, photographer Andrew Borowiec documents the Flats today and evokes the way of life they once embodied. Given the rare opportunity to access one of Cleveland's vast steel mills before it was (...) modernized or destroyed, Borowiec employed his camera to explore the Flats and its monuments of American industry. His striking black and white images reveal the broken power and vulnerability of the once-mighty mill as well as its relation to the surrounding city and its neighborhoods. The commercial buildings, factories, warehouses, and iron bridges that sustained Cleveland's industrial pulse convey a quiet dignity in these compelling photographs, as do the modest frame houses that sheltered those who labored for decades in the Flats. As Clevelanders struggle to redefine themselves as citizens of a twenty-first-century corporate metropolis, the Flats stand as a haunting testament to a time when men worked with their hands and steel was indeed the backbone of our nation. Borowiec's compassionate but unflinchingly honest gaze challenges us to look both at and beyond the images of Cleveland and to meditate on our common history of loss and rebirth. (shrink)

The blood oxygen level dependent effect that provides the contrast in functional magnetic resonance imaging has been demonstrated to affect the linewidth of spectral peaks as measured with magnetic resonance spectroscopy and through this, may be used as an indirect measure of cerebral blood flow related to neural activity. By acquiring MR-spectra interleaved with frames without water suppression, it may be possible to image the BOLD effect and associated metabolic changes simultaneously through changes in the linewidth of the unsuppressed water (...) peak. The purpose of this study was to implement this approach with the MEGA-PRESS sequence, widely considered to be the standard sequence for quantitative measurement of GABA at field strengths of 3 T and lower, to observe how changes in both glutamate and GABA levels may relate to changes due to the BOLD effect. MR-spectra and fMRI were acquired from the occipital cortex of 20 healthy participants whilst undergoing intrascanner visual stimulation in the form of a red and black radial checkerboard, alternating at 8 Hz, in 90 s blocks comprising 30 s of visual stimulation followed by 60 s of rest. Results show very strong agreement between the changes in the linewidth of the unsuppressed water signal and the canonical haemodynamic response function as well as a strong, negative, but not statistically significant, correlation with the Glx signal as measured from the OFF spectra in MEGA-PRESS pairs. Findings from this experiment suggest that the unsuppressed water signal provides a reliable measure of the BOLD effect and that correlations with associated changes in GABA and Glx levels may also be measured. However, discrepancies between metabolite levels as measured from the difference and OFF spectra raise questions regarding the reliability of the respective methods. (shrink)

Superstring theory is an extension of conventional quantum field theory that allows for stringlike and branelike material objects besides pointlike particles. The basic foundations on which the theory is built are amazingly shaky, and, equally amazingly, it seems to be this lack of solid foundations to which the theory owes its strength. We emphasize that such a situation is legitimate only in the development phases of a new doctrine. Eventually, a more solidly founded structure must be sought.Although it is advertised (...) as a “candidate theory of quantum gravity”, we claim that string theory may not be exactly that. Rather, just like quantum field theory itself, it is a general mathematical framework for a class of theories. Its major flaw could be that it still embraces a Copenhagen view on the relation between quantum mechanics and reality, while any “theory of everything”, that is, a theory for the entire cosmos, should do better than that.

The paper takes a novel approach to a classic problem—Hempel’s Raven Paradox. A standard approach to it supposes the solution to consist in bringing our inductive logic into “reflective equilibrium” with our intuitive judgements about which inductive inferences we should license. This approach leaves the intuitions as a kind of black box and takes it on faith that, whatever the structure of the intuitions inside that box might be, it is one for which we can construct an isomorphic formal (...) edifice, a system of inductive logic. By popping open the box we can see whether that faith is misplaced. I aim, therefore, to characterize our pre-theoretical, intuitive understanding of generalizations like “ravens are black” and argue that, intuitively, we take them to mean, for instance: “ravens are black by some indeterminate yet characteristic means.” I motivate and explicate this formulation and bring it to bear on Hempel’s Problem.

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

This essay surveys the writings of Walter Rodney, the late Guyanese scholar-activist, in an effort to elicit a distinctive way of thinking politically about underdevelopment. Focusing on a range of primary sources, including a series of unpublished notes and lectures on Marxism and development theory, I consider how Rodney’s engagement with the concrete struggles of Black people informed his appropriation of historical materialism. An avowed “Black Marxist” working at the onset of the neocolonial order, Rodney suggested that collective (...) human development, the historical expansion of productive and social capacity, had become routinely delimited by racially charged political blockages, the effects of a kind of zero-sum game in which development for some was secured only through the active underdevelopment of others. Ultimately I suggest that Rodney’s work invites serious reconsideration of the enduring explanatory power of the Black radical and Marxist legacies, in this case by providing a rich theoretical framework that can help to orient and sustain critical engagement with the elusive racial politics of persistent underdevelopment.

Journal of Social Philosophy, EarlyView.

Adorno's essay “On Jazz” of 1936 sees jazz as a commodity in the culture industry and as merely a perverted form of symbolic revolt against social injustice. This assessment is often echoed in his later work referring to jazz. He consequently fails to respond to the detail of the dynamic and rapid development of jazz in the twentieth century. This failure can be seen as a result of some of his assumptions about philosophical approaches to music. Adorno's focus on “what (...) jazz is really saying in social terms” is part of his aim to construct “social theory by dint of the explication of aesthetic right and wrong in the heart of the [musical] objects.” Aesthetic judgment is therefore given priority over attempts to understand the practice of jazz in relation to its social and political contexts. The significance of cultural forms like jazz as expressions of social tensions and resistance to oppression is thus neglected. At the same time, jazz's significance as a model of modern expressive sociality, which has played a role in resistance to oppression of Black Americans, can be productively analyzed using other aspects of Adorno's approach to modern music. Adorno himself, though, largely fails to do this. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 39.1 (2001) 77-99 [Access article in PDF] Malebranche's Distinction Between General and Particular Volitions Andrew Pessin "God needs no instruments to act," Malebranche writes in Search; "it suffices that He wills in order that a thing be, because it is a contradiction that He should will and that what He wills should not happen. Therefore, His power is His will." 1 God (...) acts by willing; so much is clear. But Malebranche goes further, especially in his Treatise, by asserting that (i) only in miracles and the initial creation does God act by "particular volitions," while (ii) God ordinarily acts in nature via laws or "general volitions." This distinction between general and particular volitions is central to Malebranche's theories of divine activity, theodicy, and occasionalism. Nevertheless, I will argue, it has been almost universally misunderstood.The two standard interpretations of Malebranche's expressions "general volition" and "particular volition" are these: (GC) A "general volition" for Malebranche is one whose content is general; a "particular volition" is one whose content is particular. [End Page 77](PC) All divine volitions have particular contents; but a "general volition" is one which is in accord with general laws, while a "particular volition" is one not in accord with general laws. 2Andrew Black offers the following two schemata for volition contents, where (B) also provides the general form of laws of nature: A: Let c be F at t. B: For all created substances x and y and for every time t1, if x is G at t1and x bears relation R to y then there is a time t2 such that t2 bears relation T to t1 and y is F at t2. 3(A) is "particular" insofar as it represents a particular state of affairs, involving a particular substance in a mode at a time; (B) is general in making no such reference. According to (GC), then, when Malebranche's God acts by "general volitions," He has volitions whose content is of the form of (B) (specifically, a law of nature); when He acts by particular volitions His volitions are of the form of (A). According to (PC), both general and particular volitions are of the form of (A), while the former are in accord with laws of nature and the latter aren't.To simplify matters, I will focus on God's activity in the material world; the laws of nature in question will usually be the laws of motion. Further, to avoid terminological confusion, I will refer to volitions of the form of (A) as "particular content volitions," and those of (B) as "general content volitions." The issue before us then is: When Malebranche's God acts by "general volitions," are these general content volitions or particular content volitions? Proponents of (GC) support the former; those of (PC) the latter.Unhappily, almost everything Malebranche says directly on the subject can be interpreted either way. 4 (I'll speculate why at the end.) And admittedly, what Malebranche says more broadly about natural laws and divine volitions is often suggestive of (GC)—so it is no surprise that almost all recent commentators adopt (GC), usually simply assuming it without argument. Still, I shall argue that if one of the interpretations is correct, it is (PC). [End Page 78]My plan in this paper: (1) Offer some prima facie support for (PC); (2) Provide four arguments that (PC) either fits better with, or is alone consistent with, various Malebranchean doctrines; (3) Reply to some recent objections against (PC); (4) Argue that Malebranche's direct reply to Arnauld supports (PC); (5) Offer a conclusion and final thought. 1. Some Prima Facie Support For (PC) Let me first note that Steven Nadler offers various passages which do at least suggest (PC). 5 But that evidence, while strong, is not alone conclusive. For one thing, those passages can perhaps be accommodated by (GC); 6 for another, there are many passages which suggest (GC). So we must go further.Consider, then, Malebranche's primary concern in the Treatise, the... (shrink)

This article analyzes a series of encounters between the Black Panther Party and the U.S. government’s War on Poverty, beginning with the Party’s foundation in a North Oakland anti-poverty office in 1966, and culminating with the resignation of six Party members from elected positions on a West Oakland anti-poverty board in 1973. The essay theorizes these encounters as moments in an antagonistic process whereby the Party sought to separate from and launch incursions into the state’s anti-poverty apparatus, which had (...) been established in the mid-1960s by a discrete stratum of state managers who sought to transform riotous energy into labor-power. This essay understands articles published in the Party’s newspaper, documents from its archive, and records of its community service practice as components of an ideological struggle which sought to reproduce anti-capitalist social relations on an extended scale. On the basis of this historical case study, the essay argues that the autonomy of radical social movement organizations from the state should be understood as a process rather than a status. It shows how social movements which view the state as an enemy can struggle in “close-quarters antagonism” within and against it. It situates this argument in relation to debates within the critical social sciences and state theory, and it considers the political and theoretical repercussions of this hypothesis for radical movements which confront the state apparatus of non-profit organizations today.

Offers readers an alternative way of conceptualising humanism in relation to global change, one that draws in particular from black studies as opposed to one located in the ontological fold of European humanism.

Conventional particle theories such as the Standard Model have a number of freely adjustable coupling constants and mass parameters, depending on the symmetry algebra of the local gauge group and the representations chosen for the spinor and scalar fields. There seems to be no physical principle to determine these parameters as long as they stay within certain domains dictated by the renormalization group. Here however, reasons are given to demand that, when gravity is coupled to the system, local conformal invariance (...) should be a spontaneously broken exact symmetry. The argument has to do with the requirement that black holes obey a complementarity principle relating ingoing observers to outside observers, or equivalently, initial states to final states. This condition fixes all parameters, including masses and the cosmological constant. We suspect that only examples can be found where these are all of order one in Planck units, but the values depend on the algebra chosen. This paper combines findings reported in two previous preprints (G. ’t Hooft in arXiv:1009.0669 [gr-qc], 2010; arXiv:1011.0061 [gr-qc], 2010) and puts these in a clearer perspective by shifting the emphasis towards the implications for particle models.

One of the significant factors in the recent rehabilitation of medieval philosophy has been a renewed interest in virtue ethics, so-called, for which the credit must, in large part, go to Alasdair MacIntyre. However, some now working in the field of virtue ethics appear to be embarrassed by the metaphysical or theological context in which virtue ethics had its original expression, and attempts have been made to detach the ethics from the metaphysics and the theology. Two questions frame the structure (...) of Andrew Dell’Olio’s book: first, the historical and exegetical question of how St. Thomas manages to link up the secular and the religious orders of virtue without fragmenting the unity of the moral self; the second, the thematic question of the significance of St. Thomas’s account of the virtues to contemporary discussion. The early chapters of the book attempt to show that a de-theologized presentation of St. Thomas’s ethics fails to do justice to the rich vision of the good he presents in the Summa Theologiae. Dell’Olio, convincingly in my opinion, shows that Thomas succeeds in reconciling both a natural and a supernatural orientation of the will to the good, and thus that his ethics is more than a mere representation of Aristotle’s. The central chapters discuss the issues of God and the human good, and the connection of the virtues. (shrink)
