We use the path integral form of quantum electrodynamics to show that a causal classical limit to QED can be derived by functionally integrating over the photon coordinates, starting from an initial photon vacuum and ending in a final coherent radiation state driven by the anticipated classical charged particle trajectories. The resulting charged particle transition amplitude depends only on particle coordinates. When the \ limit is taken, only those particle paths that are not constrained by the final radiation state are (...) varied. These results demonstrate that the collapse from an infinity of charged particle paths, a path integral description, to causally interacting classical trajectories, a stationary-action description, is critically dependent on including final coherent state radiation and maintaining the distinction between particle paths that are free to vary and those trajectories that can be monitored by the final state radiation.

Blair proposes that fluid intelligence, working memory, and executive function form a unitary construct: fluid cognition. Recently, our group has utilized a combined correlational–experimental cognitive neuroscience approach, which we argue is beneficial for investigating relationships among these individual differences in terms of neural mechanisms underlying them. Our data do not completely support Blair's strong position. (Published Online April 5 2006).

Contemporary tort theory is dominated by a debate between legal economists and corrective-justice theorists. Legal economists suppose that tortfeasors and tortious wrongs are false targets for cheapest cost-avoiders and avoidable future losses. Corrective-justice theorists argue powerfully that the economic account of tort as search for cheapest cost-avoiders with respect to future accidents does not capture the most fundamental fact about tort adjudication, namely, that the reason we hold defendants liable in tort is that they have wronged their victims and should (...) therefore repair the harm they have done. Deterring cheapest cost-avoiders from committing future harms no more justifies imposing liability in tort than deterring future crime justifies hanging the innocent. This is a powerful critique of the economic theory of tort, but it overshoots the mark. As an account of tort law, corrective justice puts the cart before the horse Tort is a law of wrongs, not just a law of redress for wrongs. Repairing harm wrongly done is the next best way of complying with an obligation not to do harm wrongly in the first place. Rights and remedies form a unity in which rights have priority. Corrective justice is thus an essential but subordinate aspect of tort. This paper develops this line of criticism of corrective-justice theory and offers an alternative account of tort that places primary norms of harm avoidance and respect for rights at its center. On this conception, tort isa law of wrongs, but its distinctiveness lies in the content and character of the wrongs with which it is concerned. At its core, tort is concerned with protecting essential conditions of individual agency. (shrink)

Searching for God draws upon the traditional categories of systematic theology as it guides readers through the Catholic theological thought process involved in the search for God. At each step we examine the work of a past thinker from the time of the early church up to the early twentieth century, and a present thinker whose works are often required reading in theology courses. Not only do readers have the opportunity to critically evaluate several important theological works in the Catholic (...) tradition, they can also enter into dialogue with those works as they engage in their own search for God. Among the ten categories represented are: Bible: Hearing God--Past: Hugh of St. Victor, Noah's Ark (ca. 1130) Present: Sandra Schneiders, The Revelatory Text (1999) Christ II: Understanding God (Dogmatic Approach)--Past: Cyril of Alexandria, On the Unity of Christ (429) Present: Roger Haight, Jesus: Symbol of God (1999) Religions of the World: Listening for God Past: Jean Daniélou, The Salvation of the Nations (1946) Present: Raimon Panikkar, The Experience of God (2006) +.

Cas9/guide RNA (gRNA)‐based gene drive systems are expected to play a transformative role in malaria elimination efforts., whether through population modification, in which the drive system contains parasite‐refractory genes, or population suppression, in which the drive system induces a severe fitness load resulting in population decline or extinction. DNA sequence polymorphisms representing alternate alleles at gRNA target sites may confer a drive‐resistant phenotype in individuals carrying them. Modeling predicts that, for observed levels of SGV at potential target sites and observed (...) rates of de novo DRA formation, population modification strategies are uniquely resilient to DRAs. We conclude that gene drives can succeed when fitness costs incurred by drive‐carrying mosquitoes are low enough to prevent strong positive selection for DRAs produced de novo or as part of the SGV and that population modification strategies are less prone to failure due to drive resistance.

This article investigates teachings from diverse mystical traditions and the quantum physicist, David Bohm. After a brief background on the traditions, a dialogue follows their teachings regarding these questions: How is infinite truth described? How does the phenomenal world relate to infinite truth? How do humans experience the infinite within the phenomenal world? The metaphors from quantum physics proposed by David Bohm poetically intertwine topics of emptiness, innermost awareness, sparks and relationships, storehouses and the heart, roots and souls, resurrection and (...) the truth body, and perceiving truth.

While he develops three different aspects of Lacan's “Real,” Slavoj Žižek does so only partially, in the end leaving an inconsistent and contradictory account. Here these three versions of the Real are outlined and clarified by showing their relation to Marx's account of capitalist exchange and socialist politics. This leads to a discussion of two other aspects of the Real that appear in Žižek's work: the pre-Symbolic Real and the “Sinthome.” Where the former is simultaneously the fear of a unified (...) working class and the fantasy of a world of “total enjoyment” without conflict, the latter is discussed here in terms of political struggle that takes on not only the form of a means to an end but also that of an end in itself.

In the move from a teleological notion of history to one ruled by the logic of the symptom, Žižek is pushed to theorize the notion of the Act. Bringing together Marxism and psychoanalysis at the level of surplus, revolution and the end of analysis merge. What Žižek provides is a picture of change permeated with contingencies: a hysterical ‘acting out’ can become the Act proper; a violent outburst can become revolution. This can only be accomplished with the help of the (...) party-cum-analyst, which Zizek asserts serves to ensure that spontaneity becomes politicized. This paper serves as an attempt to trace the beginnings of the theoretical contours of Žižek’s development of the Act, and ends by opening towards the investigation of the importance of Pascal’s wager in Žižek’s theoretical corpus.

The tort law of negligence is one of our principal forms of protection against accidental physical injury. But it is underspecified in one respect and incomplete in another. The common law of negligence is underspecified in that its norm of reasonable care does not register clearly enough the fact that it is reasonable to take greater precautions against some kinds of physical injuries — severe and irreparable ones — than it is against other kinds — mild and fully repairable ones. (...) The common law of negligence is incomplete in that it relies on the award of money damages to induce prospective injurers to exercise reasonable care prospectively, yet does not so much as attempt to fully monetize the harm done by unreasonable risks that result in death.

_Beyond the Pleasure Principle_ is Freud’s most philosophical and speculative work, exploring profound questions of life and death, pleasure and pain. In it Freud introduces the fundamental concepts of the “repetition compulsion” and the “death drive,” according to which a perverse, repetitive, self-destructive impulse opposes and even trumps the creative drive, or Eros. The work is one of Freud’s most intensely debated, and raises important questions that have been discussed by philosophers and psychoanalysts since its first publication in 1920. The (...) text is presented here in a contemporary new translation by Gregory C. Richter. Appendices trace the work’s antecedents and the many responses to it, including texts by Plato, Friedrich Nietzsche, Melanie Klein, Herbert Marcuse, Jacques Derrida, and Judith Butler, among many others.

Sigmund Freud, the founder of psychoanalysis, declared that religion is a universal obsessional neurosis in his famous work of 1927, _The Future of an Illusion_. This work provoked immediate controversy and has continued to be an important reference for anyone interested in the intersection of philosophy, psychology, religion, and culture. Included in this volume is Oskar Pfister’s critical engagement with Freud’s views on religion. Pfister, a Swiss pastor and lay analyst, defends mature religion from Freud’s “scientism.” Freud’s and Pfister’s texts (...) have been updated in Gregory C. Richter’s translations from the original German. (shrink)

Mounting evidence shows that nature contact is associated with affective benefits. However, the psychological mechanisms responsible for these effects are not well understood. In this study, we examined whether more time spent in nature was associated with higher levels of positive affect in general, and lower levels of negative affect and rumination in general. We also conducted a cross-sectional mediation analysis to examine whether rumination mediated the association of nature contact with affect. Participants reported their average time spent in nature (...) each week, as well as their general levels of positive and negative affect, and the degree to which they typically engaged in rumination in daily life. We then used structural equation modeling to test our hypotheses. Our results support the hypothesis that nature contact is associated with general levels of affect, and that rumination mediates this association for negative affect, and marginally mediates this association for positive affect.

After a period of inactivity, interest in explanationism as a thesis about the nature of epistemic justification has been renewed. Poston and McCain have both recently offered versions of explanationist evidentialism. In this paper, we pose two objections to explanationist evidentialism. First, explanationist evidentialism fails to state a sufficient condition for justification. Second, explanationist evidentialism implies a vicious regress.

Writing in the late 1990s about the tendency of encyclopedists to designate existentialism a finished project, Thomas W. Busch cautions that such hasty periodization risks distorting our understanding of the contemporary philosophical scene and of depriving ourselves of vital resources for critiquing contemporary forms of oppression, what Garbriel Marcel referred to as processes of dehumanization. We should recall that "existentialism made possible present forms of Continental philosophy, all of which assume the existentialist critique of dualism, essentialism, and totality in modern (...) philosophy," and we should acknowledge that "existentialism remains capable of haunting today's scene as an important and relevant critic." Offered in honor of Thomas W. Busch after his more than fifty years of work in philosophy, the essays in this volume attest to existentialism as a living project. The essays are written by scholars who championed existentialism in America and by scholars who now seek to extend existentialist insights into new territory, including into research in cognitive science. The essays range from studies of key figures and texts to explorations of urgent topics such as the nature of freedom and the possibility of what Busch calls "incorporation," a sense of communicative solidarity that respects difference and disagreement.

End-of-life decision making is fraught with ethical challenges. Withholding or withdrawing life support therapy is widely considered ethical in patients with high treatment burden, poor premorbid status, or significant projected disability even when such treatment is not “futile.” Whether such withdrawal of therapy in the aftermath of attempted suicide is ethical is not well established in the literature. We provide a clinical vignette and propose criteria under which such withdrawal would be ethical. We suggest that it is appropriate to withdraw (...) life support, regardless of the cause of the critical illness or disability, when the following criteria are met: Surrogates request withdrawal of care and the adequacy of surrogates is confirmed, an external reasonability standard is met, passage of time, perhaps 72 hours, to allow certainty regarding the patient's wishes, and psychiatric morbidity should be considered as grounds for withdrawal only in truly treatment-refractory cases. Fundamentally, we believe the question to ask is, “If this were not an attempted suicide, would a request to withdraw care be reasonable?” We believe that under these circumstances, such withdrawal of life support, even in an individual who has attempted suicide, does not constitute physician assistance with suicide and is distinct from physician aid-in-dying in several important respects.

From a traditional moral point of view, business practitioners often seem overly concerned about the behavior of their peers in deciding how they ought to act. We propose to account for this concern by introducing a mutual trust perspective, where moral obligations are grounded in a sense of trust that others will abide by the same rules. when grounds for trust are absent, the obligation is weakened. We illustrate this perspective by examining the widespread ambivalence with regard to deception about (...) one's settlement preferences in negotiation. On an abstract level, such deception generally seems undesirable, though in many individual cases it is condoned, even admired as shrewd bargaining. Because of the difficulty in verifying someone's settlement preferences, it is hard to establish a basis for trusting the revelations of the other party, especially in competitive negotiations with relative strangers.

The ideas contained in Karl Popper's The Open Society and Its Enemies—one of the most important tracts in political philosophy in the twentieth century—are relevant to anyone seeking to understand the recent history of the East Asian economies. Even though Popper wrote his tract to provide an explanation for both the rise and objectionable nature of totalitarian regimes in Europe in the twentieth century, many of the arguments that he advanced in this European context also explain the social, political and (...) economic relationships that are seen in modern South Eastern Asian economies. The narrative of this book is driven by a research agenda that is inter-disciplinary in nature, since to make the link between the Popperian framework and East Asian socio-economic relationships the contributing authors needed to draw upon research fields as far apart as political philosophy and East-Asian studies. With one or two exceptions, however, nearly all of the contributing authors have a background in economics, and this background is reflected in the way that they have sought to tackle the research question. This book is, in short, an inter-disciplinary exercise undertaken from an economics perspective, and hence it may best be described as an exercise in political economy rather than pure analytical economics. The novelty of juxtaposing Popperian ideas with a discussion of social, political and economic development in South East Asia makes this narrative of interest to both political philosophers and specialists in South East Asian economies. The key insight drawn from the analysis is that although Karl Popper's The Open Society and Its Enemies was a product of a European time and place, it is also relevant to anyone seeking to understand the recent history of the East Asian economies.

As individual subjects, creativity and personality have been the focus of much research and many publications. This Cambridge Handbook is the first to bring together these two topics and explores how personality and behavior affects creativity. Contributors from around the globe present cutting-edge research about how personality traits and motives make creative behavior more likely. Many aspects of personality and behavior are examined in the chapters, including genius, emotions, psychopathology, entrepreneurship, and multiculturalism, to analyse the impact of these on creativity. (...) The Cambridge Handbook of Creativity and Personality Research will be the definitive resource for researchers, students and academics who study psychology, personality, and creativity.

As a way forward in assessing how the Old Testament wisdom tradition might speak to decisions in a modern medical context, in this paper, I propose exploring the iconographic function of the “tree of life” in the Old Testament, which is consistently associated with both wisdom as well as life and health, in order to tease out two-related issues that can help in providing a Christian theological framework for thinking about the problem of the medicalization of risk: first, how should (...) the natural and good human desire for health and long life be framed in terms of the pursuit of wisdom? And, second, how might a sapientially formed character approach risk and uncertainty in making medical decisions? The answers to these questions help establish a framework in which more specific questions related to the medicalization of risk can be assessed. As such, this paper is deliberately programmatic and perspectival rather than prescriptive. (shrink)

The tomb of the ancient Pharaoh, Tut-ankh-Amen, was opened some years ago. Lord Carnarvon, who financed the investigations, died shortly after the opening. Lord Westbury fell to his death from the high window of a London flat on February 21, 1930. His son, the Hon. Richard Bethell, had been found dead in his room the previous November. He was secretary to Mr. Howard Carter, one discoverer of Tut-ankh-Amen’s tomb. Many persons who had been connected with the excavations had died previously—M. (...) Benedite, for example, died after participating in the research, and Mrs. Greely committed suicide after visiting the tomb. The Hon. Richard Bethell was the thirteenth person connected with Tut-ankh-Amen's tomb, directly or indirectly, to die, and his father, Lord Westbury, was the fourteenth. The death of Lord Carnarvon, a few weeks after the tomb was opened, stirred the notion that a curse had been placed on the mummy of the Pharaoh, or in his tomb, to menace violators. Succeeding deaths kept the notion alive, and the thirteenth death, of the Hon. Richard Bethell, wrung an opinion from Dr. Mardus, the eminent French Egyptologist. He was convinced that the ancient Egyptians could surround “their mummies with some dynamic force.” Such a force lurked in the tomb of Tut-ankh-Amen. Its nature was unknown, but it had manifested itself in the series of deaths. (shrink)

Ralph Cudworth, Doctor of Divinity, Master of Christ’s College at Cambridge, and philosophical chieftain of the Cambridge Platonists, published The True Intellectual System of the Universe in 1678 to disprove “the fatal necessity of all actions and events.” This disproof would destroy the various atheisms founded upon such “fatal necessity”; it would also correct those Christians who mistakenly honoured God by subjecting men to a divinely administered fate. Cudworth, with a constant eye on Hobbes, whom he did not name, struck (...) at atheism by establishing a “true intellectual system” and by arguing away its principle of fate. His design swelled as he worked to meet the various versions of “fatal necessity” with the various atheisms founded upon them, to establish the true doctrine, and to accommodate his own copious learning, and it swelled too much for the published work to be more than a first instalment of his whole design.

A young boy found one of Beck's best stereoscopes, but he did not understand its use. When he looked through the two eye-pieces at the two adjacent duplicates of each picture on each card he got a single flat picture, and he expected nothing more. Then the moment of revelation came. As he fumbled the focus onto a flat picture of Hamlet, the grave-diggers and Hamlet himself bulged out, the skull on Hamlet's palm looked like a museum piece, and the (...) grave yawned like a real pit. The stereoscopic world of the Beck instrument had been suddenly established in the boy's experience. (shrink)
