The present study was designed to explore the relationship between self-reported dissociative experiences and performance in tasks eliciting right-hemisphere processing load. Thirty-four participants performed a vigilance task in two conditions: with task-irrelevant negative-arousing pictures and task-irrelevant neutral pictures. Dissociation was assessed with the Dissociative Experience Scale. Consistent with theories positing right-hemisphere deregulation in high non-clinical dissociators, dissociative experiences correlated with greater vigilance decrement only in the negative picture condition. As both the vigilance task and negative picture processing are right lateralized, (...) this result provides support for a right-hemisphere dysfunction in high dissociators, at least in negative conditions.

Though Frege was interested primarily in reducing mathematics to logic, he succeeded in reducing an important part of logic to mathematics by defining relations in terms of functions. By contrast, Whitehead & Russell reduced an important part of mathematics to logic by defining functions in terms of relations (using the definite description operator). We argue that there is a reason to prefer Whitehead & Russell's reduction of functions to relations over Frege's reduction of relations to functions. There is (...) an interesting system having a logic that can be properly characterized in relational but not in functional type theory. This shows that relational type theory is more general than functional type theory. The simplification offered by Church in his functional type theory is an over-simplification: one can't assimilate predication to functional application.<br>. (shrink)

Review of Nicholas Capaldi, Hume's Place in Moral Philosophy -/- In Hume’s Place in Moral Philosophy Professor Capaldi attempts “to construct a coherent account of Hume’s moral philosophy both with an eye to those issueswhich have persistently vexed his readers and commentators and with the intent of underscoring those novel and challenging aspects of his moral philosophy which ...remain unnoticed or unappreciated” (p.xi).Capaldi’s project falls into three distinct, but related, parts. First, he provides a “brief sketch of the intellectual milieu (...) in which Hume was writing”. Many of the misunderstandings of Hume’s philosophy, Capaldi suggests, “are largely the result of failing to see the specific issues and opponents Hume had in mind” (p. 28 - cp. p. 93). O n this matter Capaldi’s overall view is that Hume’s moral thought may be interpreted as an effort to incorporate “Hutcheson’s moral philosophy and teachings into a more fundamental framework which can only be described as Newtonian” (p.21). Throughout this work Capaldi is particularly at pains to emphasise Hume’s (supposed) antagonism to Hobbes’s “selfish system” of morals (e.g. pp. 5-9, 13, 23, 198-99, 209-10, 292, 298, 301). Second, Capaldi cites four “major issues within moral philosophy” which structure his own interpretation of various specific aspects of Hume’s moral thought. The four issues are: (i) the existence of a “moral domain”; (ii) the nature of our “access” to this domain; (iii) the relationship between “moral apprehension” and “moral motivation”; and, finally, (iv) the relationship between “moral motivation” and “non-moral motivation” (p. 2). It is largely within this framework that Capaldi discusses the familiar issues concerning moral obligation, moral judgement, sympathy, moral sentiment, and justice. Third, Capaldi’s principal concern in this study is to present an account or description of Hume’s ‘Copernican Revolution in Philosophy’. This “revolution" is described in terms of the shift from the ‘Ithink’ to the ‘WeDo’ perspective (see esp.pp.21-7 andCh. 8).This feature of Hume’s philosophical thought has, Capaldi claims, been insufficiently understood and this has resulted in both unnecessary misunderstanding and misplaced criticism of Hume’s moral thought....

John Danford claims that Hume's philosophy must be understood within the framework of the 'problem of reason'. The problem of reason', according to this account, concerns the general relationship between philosophy and reason, on the one hand, and experience and 'common life' on the other. Danford maintains that the nature and development of Hume's thought, considered as a response to this problem, falls, essentially, into two parts. First, we must consider Hume's Treatise and his first Enquiry (ie., his 'epistemological works' (...) [61-cp.9]). The heart of Hume's Treatise, Danford suggests, lies with the epistemology of Book I and, in particular, with the discussions of causation and the external world. Hume's primary concern in these passages, it is argued, was to refute and discredit the rationalistic, 'scientific philosophies of Descartes and, especially, Hobbes (24-5, 40-5, 59, 74-5, 84-5, 190). These thinkers, Danford maintains, had driven a 'wedge' between philosophy and experienceor 'common life' (24-5). By emphasizing the limits and weakness of h u m a n understanding Hume exposes the vulnerability of Hobbes's and Descartes's scientific ambitions and, in this way, he seeks to return philosophy to the secure and appropriate foundations of 'common life and everyday experience.....Shortly after Hume published the Treatise there was, Danford claims, a 'shift' in his thinking on these matters (28). This shift is represented most clearly in his later works: the Essays, the History, and the Dialogues (10, 33, 7, 88, 108). Danford firmly rejects the suggestion that these works represent a turning away from philosophy. On the contrary, it is these later works, taken together, which constitute Hume's most mature philosophy. Indeed, they are, Danford says, the 'flower ofHume's philosophic career' (10). The mature philosophy of Hume, it is argued, must be interpreted as 'Political philosophy". It is political philosophy in the sense that it attempts to investigate human life in its full diversity and complexity and, on this basis, it seeks to provide us with some general guide as to how we should live (10, 7, 88-9, 183-6). From the 'teachings' of the History and the Essays Danford draws some lessons that are 'valid for all times' (112 and 114). The inspirational message concerns, roughly, the merits of capitalism (see, e.g., p. 131: The increase in personal liberty, then, was and is directly connected to the growth of commerce...' and p.137:'. the central lesson of British history [is] the superiority of liberal commercial society ...).

Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and (...) On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)

For several terms at Cambridge in 1939, Ludwig Wittgenstein lectured on the philosophical foundations of mathematics. A lecture class taught by Wittgenstein, however, hardly resembled a lecture. He sat on a chair in the middle of the room, with some of the class sitting in chairs, some on the floor. He never used notes. He paused frequently, sometimes for several minutes, while he puzzled out a problem. He often asked his listeners questions and reacted to their replies. Many meetings were (...) largely conversation. These lectures were attended by, among others, D. A. T. Gasking, J. N. Findlay, Stephen Toulmin, Alan Turing, G. H. von Wright, R. G. Bosanquet, Norman Malcolm, Rush Rhees, and Yorick Smythies. Notes taken by these last four are the basis for the thirty-one lectures in this book. The lectures covered such topics as the nature of mathematics, the distinctions between mathematical and everyday languages, the truth of mathematical propositions, consistency and contradiction in formal systems, the logicism of Frege and Russell, Platonism, identity, negation, and necessary truth. The mathematical examples used are nearly always elementary. (shrink)

The nature/nurture debate is not dead. Dichotomous views of development still underlie many fundamental debates in the biological and social sciences. Developmental systems theory offers a new conceptual framework with which to resolve such debates. DST views ontogeny as contingent cycles of interaction among a varied set of developmental resources, no one of which controls the process. These factors include DNA, cellular and organismic structure, and social and ecological interactions. DST has excited interest from a wide range of researchers, from (...) molecular biologists to anthropologists, because of its ability to integrate evolutionary theory and other disciplines without falling into traditional oppositions. The book provides historical background to DST, recent theoretical findings on the mechanisms of heredity, applications of the DST framework to behavioral development, implications of DST for the philosophy of biology, and critical reactions to DST.

The cuticular surface of Drosophila is decorated by parallel arrays of polarized structures such as hairs and sensory bristles; for example, on the wing each cell produces a distally pointing hair. These patterns are termed [tissue polarity]. Several genes are known whose activity is essential for the development of normal tissue polarity. Mutations in these genes alter the orientation of the hair or bristle with respect to neighboring cells and the body as a whole. The phenotypes of mutations in these (...) genes allows them to be placed in three phenotypic groups. Based on their behavior in genetic mosaics, it has proved possible to determine that individual genes are required either for the generation of an intercellular polarity signal and/or the transduction of that signal to the cytoskeleton.

Over recent years, the research community has been increasingly using preprint servers to share manuscripts that are not yet peer-reviewed. Even if it enables quick dissemination of research findings, this practice raises several challenges in publication ethics and integrity. In particular, preprints have become an important source of information for stakeholders interested in COVID19 research developments, including traditional media, social media, and policy makers. Despite caveats about their nature, many users can still confuse pre-prints with peer-reviewed manuscripts. If unconfirmed but (...) already widely shared first-draft results later prove wrong or misinterpreted, it can be very difficult to “unlearn” what we thought was true. Complexity further increases if unconfirmed findings have been used to inform guidelines. To help achieve a balance between early access to research findings and its negative consequences, we formulated five recommendations: (a) consensus should be sought on a term clearer than ‘pre-print’, such as ‘Unrefereed manuscript’, “Manuscript awaiting peer review” or ‘’Non-reviewed manuscript”; (b) Caveats about unrefereed manuscripts should be prominent on their first page, and each page should include a red watermark stating ‘Caution—Not Peer Reviewed’; (c) pre-print authors should certify that their manuscript will be submitted to a peer-review journal, and should regularly update the manuscript status; (d) high level consultations should be convened, to formulate clear principles and policies for the publication and dissemination of non-peer reviewed research results; (e) in the longer term, an international initiative to certify servers that comply with good practices could be envisaged.

Web-based platforms play an increasingly important role in managing and sharing research data of all types and sizes. This article presents a case study of the data storage, sharing, and management platform Figshare. We argue that such platforms are displacing and reconfiguring the infrastructure of norms, technologies, and institutions that underlies traditional scholarly communication. Using a theoretical framework that combines infrastructure studies with platform studies, we show that Figshare leverages the platform logic of core and complementary components to re-integrate a (...) presently splintered scholarly infrastructure. By means of this logic, platforms may provide the path to bring data inside a scholarly communication system still optimized mainly for text publications. Yet the platform strategy also risks turning over critical scientific functions to private firms whose longevity, openness, and corporate goals remain uncertain. It may amplify the existing trend of splintering infrastructures, with attendant effects on equity of service. (shrink)

Developmental systems theory (DST) is a general theoretical perspective on development, heredity and evolution. It is intended to facilitate the study of interactions between the many factors that influence development without reviving `dichotomous' debates over nature or nurture, gene or environment, biology or culture. Several recent papers have addressed the relationship between DST and the thriving new discipline of evolutionary developmental biology (EDB). The contributions to this literature by evolutionary developmental biologists contain three important misunderstandings of DST.

The 1994 biography of Lenin by General Dmitri Volkogonov, the chairperson of President Yeltsin's commission for examining the Soviet archives, has been hailed as exposing Lenin's crimes. Volkogonov charges that Lenin's fanaticism caused him to order acts of inhuman cruelty; that he was an agent of the German government; that the October revolution was the coup of a minority; that Lenin was the originator of the idea of a one-party dictatorship; that he persecuted religious believers; and that he created the (...) totalitarian system that was perfected by Stalin. Volkogonov's evidence from archival and other sources is examined, and his charges are found to be unjustified. (shrink)

We present an analysis of Szilard's one-molecule Maxwell's demon, including a detailed entropy accounting, that suggests a general theory of the entropy cost of information. It is shown that the entropy of the demon increases during the expansion step, due to the decoupling of the molecule from the measurement information. It is also shown that there is an entropy symmetry between the measurement and erasure steps, whereby the two steps additivelv share a constant entropy change, but the proportion that occurs (...) during each of the two steps is arbitrary. Therefore the measurement step may be accompanied by an entropy increase, a decrease, or no change at all, and likewise for the erasure step. Generalizing beyond the demon, decorrelation between a physical system and information about that system always causes an entropy increase in the joint system comprised of both the original system and the information. Decorrelation causes a net entropy increase in the universe unless, as in the Szilard demon, the information is used to decrease entropy elsewhere before the correlation is lost. Thus, information is thermodynamically costly precisely to the extent that it is not used to obtain work from the measured system. (shrink)

The director of Courage International talks about the work of the apostolate in addressing homosexuality according to the mind and heart of the Church, which he calls “one of the most demanding aspects of education, formation, and pastoral care today.” But it is also an opportunity to attend to the often acute and persistent wounds of those who need healing within what Pope Francis calls the “field hospital” of the Church. The author points out that the work of Courage is (...) not first about homosexuality but about what it means to be human. It is an invitation to consider the question of the fulfillment of the human heart according to God’s gracious plan. National Catholic Bioethics Quarterly 15.2 : 221–230. (shrink)

In 2004, Google embarked on a massive book digitization project. Forty library partners and billions of scanned pages later, Google Book Search has provided searchable text access to millions of books. While many details of Google’s conversion processes remain proprietary secret, here we piece together their general outlines by closely examining Google Book Search products, Google patents, and the entanglement of libraries and computer scientists in the longer history of digitization work. We argue that far from simply “scanning” books, Google’s (...) efforts may be characterized as algorithmic digitization, strongly shaped by an equation of digital access with full-text searchability. We explore the consequences of Google’s algorithmic digitization system for what end users ultimately do and do not see, placing these effects in the context of the multiple technical, material, and legal challenges surrounding Google Book Search. By approaching digitization primarily as a text extraction and indexing challenge—an effort to convert print books into electronically searchable data—GBS enacts one possible future for books, in which they are defined largely by their textual content.

Faith-based, transformational development organizations infrequently utilize impact assessment tools as learning activities. The author argues that the real and significant barriers to program assessment can be managed if shared learning becomes a core value within the organization. By integrating Biblical teaching and program assessment activities with what it means to be a learning organization, the paper outlines a strategy for sharing valuable experiences about holistic development within and outside the faith-based development community.

There are 43 million forcibly displaced people in the world, and they are categorized along a spectrum ranging from legal issues to humanitarian concerns for protection. Despite the complex efforts to provide protection to all those in need, the issues remain blurred and many fall through the cracks. The understanding of forced displacement needs to include aspects of personhood, and the example in John 4:4—26 highlights the possibility of a collective approach to understanding forced displacement as one that is rooted (...) in the notion and importance of the person.

"Since the end of the last century," Walter Benjamin wrote, "philosophy has made a series of attempts to lay hold of the 'true' experience as opposed to the kind that manifests itself in the standardized, denatured life of the civilized masses. It is customary to classify these efforts under the heading of a philosophy of life. Towering above this literature is Henri Bergson's early monumental work, Matter and Memory."Along with Husserl's Ideas and Heidegger's Being and Time, Bergson's work represents one (...) of the great twentieth-century investigations into perception and memory, movement and time, matter and mind. Arguably Bergson's most significant book, Matter and Memory is essential to an understanding of his philosophy and its legacy.This new edition includes an annotated bibliography prepared by Bruno Paradis.Henri Bergson was awarded the Nobel Prize in 1927. His works include Time and Free Will, An Introduction to Metaphysics, Creative Evolution, and The Creative Mind. (shrink)

Why do we have a brain? After all, it's a good deal of trouble. A brain is very expensive; a hefty percentage of our cardiac output goes towards its nourishment. A brain is fragile. If you cut off its groceries for even a few minutes, it's gone, taking the rest of us with it. Worst of all, it is highly likely that pain, fear, sadness and other undesirable states require a brain. None of these things are issues for our brainless (...) relatives, such as lichens or pond scum. On the other hand, a brain comes in handy sometimes. Its very useful at tax time.
