In his metaphysical summa of 1986, The Plurality of Worlds, David Lewis famously defends a doctrine he calls ‘modal realism’, the idea that to account for the fact that some things are possible and some things are necessary we must postulate an infinity possible worlds, concrete entities like our own universe, but cut off from us in space and time. Possible worlds are required to account for the facts of modality without assuming that modality is primitive – that there are (...) irreducibly modal facts. We argue that on one reading, Lewis’s theory licenses us to assume maverick possible worlds which spread through logical space gobbling up all the rest. Because they exclude alternatives, these worlds result in contradictions, since different spread worlds are incompatible with one another. Plainly Lewis’s theory must be amended to exclude these excluders. But, we maintain, this cannot be done without bringing in modal primitives. And once we admit modal primitives, bang goes the rationale for Lewis’s modal realism. (shrink)

In this paper it is exactly proved that the standard transformations of the three-dimensional (3D) vectors of the electric and magnetic fields E and B are not relativistically correct transformations. Thence the 3D vectors E and B are not well-defined quantities in the 4D space-time and, contrary to the general belief, the usual Maxwell equations with the 3D E and B are not in agreement with the special relativity. The 4-vectors E a and B a , as well-defined 4D quantities, (...) are introduced instead of ill-defined 3D E and B. The proof is given in the tensor and the Clifford algebra formalisms. (shrink)

Data taken by the Mark II detector at the PEP storage ring was used to measure the rate of dilepton production in multihadronic events produced by e+e- annihilation at √s=29 GeV. We determine the probability that a hadron initially containing a b quark decays to a positive lepton to be 0.17-0.08+0.15, with 90% confidence level limits of 0.06 and 0.38. © 1990.

ABSTRACTThis article addresses the ways in which art and philosophy have been discursively used to conceptualize critical political changes and frame narratives of liberation by including and excluding primitive consciousness simultaneously. More concretely, it analyzes the contribution of art and philosophy to the understanding of history and post-history through different representations of black bodies, black desires, and black agencies in the novels She by Rider Haggard and The Quest of the Silver Fleece by W. E. B. Du Bois. At stake (...) is the question of the archeology of the past as a living memory in the post-historical time. This past is politically relevant especially if its cognitive fossils negate the idea of exhausted primitive consciousness in the modern world and give meanings to incongruous bedfellows such as civilization and slavery, neoliberalism and poverty, democracy and Nazism, globalization, terrorism and racism, liberalism and homophobia. Arguably, the triumph of scientifi... (shrink)

Diagrams make it possible to present scientific facts in more abstract and generalized form. While some detail is lost, simplified and accessible knowledge is gained. E. B. Wilson's work in cytology provides a case study of changing uses of diagrams and accompanying abstraction. In his early work, Wilson presented his data in photographs, which he saw as coming closest to “fact.” As he gained confidence in his interpretations, and as he sought to provide a generalized textbook account of cell development, (...) he relied on increasingly abstract diagrams. In addition, he came to see that highly abstract and even schematic drawings could provide more than pictures directly from life. (shrink)

H.B.D. Kettlewell is best known for his pioneering work on the phenomenon of industrial melanism, which began shortly after his appointment in 1951 as a Nuffield Foundation research worker in E.B. Ford's newly formed sub-department of genetics at the University of Oxford. In the years since, a legend has formed around these investigations, one that portrays them as a success story of the 'Oxford School of Ecological Genetics', emphasizes Ford's intellectual contribution, and minimizes reference to assistance provided by others. The (...) following essay reviews the important influence Ford, E.A. Cockayne, and P.M. Sheppard played in Kettlewell's research, leading up to his most famous experiments in 1953. It documents several reasons for doubting that Ford was as intellectually involved in the design of these investigations as he has previously been portrayed. It clarifies Kettlewell's intellectual contribution to the investigations for which he is famous, as well as the pivotal roles Cockayne and Sheppard played in the design, execution and interpretation of these investigations.

Between 1957 and 1961, W. E. B. Du Bois wrote a lengthy work of historical fiction, a trilogy collectively titled The Black Flame. Through the lenses of four American families, the narrative offers an illuminating glimpse into the American, political drama of the late 19th and early 20th centuries, focusing on the degree to which “the negro problem” featured in important decisions and events. Reiterating ideas found in his other works—like Black Reconstruction —the narrative foregrounds the gravity of the “Negro (...) Problem” in the formation and constitution of American culture and political institutions.While this paper will examine a few of the specific arguments that emerge from The Black... (shrink)

ExcerptThe Summer 2010 issue of Telos contained an article by Rebecca E. Karl in which she alleged that, as President of the Association for Asian Studies, I argued in an “inaugural AAS speech’” that “the current appeal to a Confucian-inspired harmonious society (hexie shehui) provides evidence for the fact that the old Confucian lack of rights-thinking is the cultural basis for the CCP's lack of rights thinking.”1 No citation or footnote was offered for this allegation. First, let me clarify (...) that I never delivered an “inaugural AAS speech.” My official speech as president of the Association for Asian Studies was…. (shrink)

This article examines the ways in which E. B. Bax and R. G. Collingwood attempted to avoid relativism and irrationalism without postulating a pure and universal reason. Both philosophers were profound historicists who recognized the fundamentally particular nature of the world. Yet they also attempted to retain a universal aspect to thought - Bax through his distinction between the logical and alogical realms, and Collingwood through his doctrine of re-enactment. The article analyses both their metaphysical premises and their philosophies of (...) history. Finally an attempt is made to use their arguments as starting-points from which to arrive at a historicist resolution of the problems of relativism and irrationalism. (shrink)

While psychoanalysis credits the entrenchment of systems of subordination to the necessity of socialization and the transmission of dominant values from parent to child, by claiming social symbolics independent of the dominant hegemony, W.E.B. Du Bois calls for resistant forms of identification. Psychoanalyticaccounts of social power relations often assume that the dominant social group produces the only operative social symbolic and that this symbolic is also identical with the nation, but Du Bois’s attention to the slave song allows him to (...) trace the burial of a black American symbolic rather than a traumatic inculcation of the dominant white symbolic.

The black social gospel emerged from the trauma of Reconstruction to ask what a “new abolition” would require in American society. It became an important tradition of religious thought and resistance, helping to create an alternative public sphere of excluded voices and providing the intellectual underpinnings of the civil rights movement. This tradition has been seriously overlooked, despite its immense legacy. In this groundbreaking work, Gary Dorrien describes the early history of the black social gospel from its nineteenth-century founding to (...) its close association in the twentieth century with W. E. B. Du Bois. He offers a new perspective on modern Christianity and the civil rights era by delineating the tradition of social justice theology and activism that led to Martin Luther King Jr. (shrink)

In this book, Mocombe illustrates ways that Barack Obama is the embodiment of the social identity as the liberal black Protestant heterosexual male. This is an identity best represented in the work of W.E.B. Du Bois.

We need to consider, and often choose, other routes to helping the poor—including ethical to u rism and fair trade in lu x u ry goods. We will not be able to invest in such feasible routes if we give away all our extra income, as Singer recommends. Sticking to donation above all, when a combination of other strategies is necessary, is highly likely to harm the poor. Si n ger doe s n’t re a lly en ga ge my argumen t .

The apolipoprotein E gene plays an important role in the pathogenesis of Alzheimer's disease , and amyloid plaque comprised mostly of the amyloid-beta peptide ) is one of the major hallmarks of AD. However, the relationship between these two important molecules is poorly understood. We examined how A treatment affects APOE expression in cultured cells and tested the role of the transcription factor NF-B in APOE gene regulation. To delineate NF-B's role, we have characterized a 1098 nucleotide segment containing the (...) 5'-flanking region of the human APOE gene . Sequence analysis of this region suggests the presence of two potential NF-B elements. To demonstrate promoter activity, the region was cloned upstream of a promoterless luciferase gene. This segment was able to drive expression of luciferase in transient transfections of human fetal glial cells. Promoter activity was stimulated twofold by A treatment. Pretreatment with double-stranded DNA decoy oligonucleotides against NF-B reduced A stimulation. Deletion and mutagenetic analyses demonstrated that the distal NF-B element was functional and showed a strong DNA-protein complex band in gel shift analysis, similar to that from control NF-B consensus element. An anti-inflammatory and anti-NF-B drug, sodium salicylate, significantly blocked A-induced APOE promoter function. Our data provide evidence that upregulation of APOE by A in astroglial cells is mediated by an NF-B-element present in the 5'-flanking region of the APOE gene. (shrink)

The physical origin of inertial forces is shown to be a consequence of the local interaction of Dirac's real covariant ether model(1) with accelerated microobjects, considered as real extended particlelike solitons, piloted by surrounding subluminal real wave fields packets.(2) Their explicit form results from the application of local inertial Lorentz transformations to the particles submitted to noninertial velocitydependent accelerations, i.e., constitute a natural extension of Lorentz's interpretation of restricted relativity.(3) Indeed Dirac's real physical covariant ether model implies inertial forces if (...) one considers the real accelerated noninertial motions of general relativity, defined within the absolute local inertial frames associated with the observed local isotropy of the 2.7° K background microwave radiation.(4) Inertia thus appears as a necessary consequence of the real particle motions described by the E.d.B.B. formalism of quantum mechanics.

Paul E. Meehl and B. F. Skinner, two of the foremost psychological theorists of the 20th century, overlapped at the University of Minnesota in the early 1940s when Skinner was a faculty member and Meehl was a graduate student. Though Skinner was well aware of, and influenced by, early 20th century physiology, he eschewed reductionism, developing his analysis of behavior without reference to concepts at another level of analysis. Meehl's theoretical approach transcended levels of analysis, drawing upon data and concepts (...) from genetics, neuroscience, and psychology. In this paper the functional components of Meehl's (1990) "Toward an Integrated Theory of Schizotaxia, Schizotypy, and Schizophrenia" paper are re-formulated substituting autism as the condition of interest. Skinner's and Meehl's theoretical frameworks are integrated with recent findings in genetics and neuroscience in an attempt to better understand the reasons why Intensive Early Behavior Therapy (IEBT) provided to children with Autism Spectrum Disorders produces enduring improvements in social, language, and cognitive functioning.

Resenha do livro de: Gareth B. Matthews. A Filosofia e a Criança.

This paper sheds new light on Samuelson’s early methodology as presented in his Foundations of Economic Analysis by reflecting on the similarity between his mathematical economics and Edwin B. Wilson’s mathematics. Wilson was Samuelson’s professor of advanced mathematical and statistical economics; he was also a protégé of Josiah Willard Gibbs. Wilson defined mathematics as a language that consisted of three interconnected aspects: postulational, axiomatic, and operational. In his Foundations, in a Wilsonian style, Samuelson wrote in the opening page, ‘Mathematics is (...) a Language’ and claimed that he offered operationally meaningful theorems. In this paper, it is argued that these maxims embodied Wilson’s approach, which framed Samuelson’s mathematical and statistical thinking around 1940 and which led him to present his work as being mathematically, theoretically, and empirically well founded. Wilson’s and Percy Bridgman’s operational methodologies are also compared and Wilson is presented as a mediator between Bridgman and Samuelson. (shrink)

In this essay, I argue that Hegel’s model of ethical life is normatively gripping for Du Bois’s critique of Radical Reconstruction. My argument proceeds in three steps. First, I use Du Bois’s insights to explain the nature of progressive political change in historical time, an account Hegel lacks. I reconstruct the normative basis of Du Bois's political critique by articulating the three essential features of public reasoning qua citizenship. Second, I defend the promise of black civic enfranchisement with respect to (...) the institutional conditions of love and labour in the wake of the Civil War. Third, I establish the central role black freedmen played in realizing the ideals of democratic self-governance affirmed in principle but seldom realized in practice in the United States. (shrink)
