A collection of 13 papers by David Lewis, written on a variety of topics including causation, counterfactuals and indicative conditionals, the direction of time, subjective and objective probability, explanation, perception, free will, and rational decision. The conclusions reached include the claim that time travel is possible, that counterfactual dependence is asymmetrical, that events are properties of spatiotemporal regions, that the Prisoners’ Dilemma is a Newcomb problem, and that causation can be analyzed in terms of counterfactual dependence between events. These (...) papers can be seen as a “prolonged campaign” for a philosophical position Lewis calls “Humean supervenience,” according to which “all there is to the world is a vast mosaic of local matters of particular fact,” with all global features of the world thus supervening on the spatiotemporal arrangement of local qualities.

David McNeill, a pioneer in the ongoing study of the relationship between gesture and language, here argues that gestures are active participants in both speaking and thinking. He posits that gestures are key ingredients in an “imagery-language dialectic” that fuels speech and thought. The smallest unit of this dialectic is the growth point, a snapshot of an utterance at its beginning psychological stage. In _Gesture and Thought,_ the central growth point comes from a Tweety Bird cartoon. Over the course (...) of twenty-five years, the McNeill Lab showed this cartoon to numerous subjects who spoke a variety of languages, and a fascinating pattern emerged. The shape and timing of gestures depends not only on what speakers see but on what they take to be distinctive; this, in turn, depends on the context. Those who remembered the same context saw the same distinctions and used similar gestures; those who forgot the context understood something different and changed gestures or used none at all. Thus, the gesture becomes part of the growth point—the building block of language and thought. _Gesture and Thought _is an ambitious project in the ongoing study of how we communicate and how language is connected to thought.

This book uncovers the lost history of Christianity's encounters with Pythagorean ideas before the Renaissance. David Albertson skillfully examines ancient and medieval theologians, particularly Thierry of Chartres and Nicholas of Cusa, who successfully reconceived the Trinity and the Incarnation within the framework of Greek number theory. David Albertson challenges modern assumptions about the complex relationship between religion and science.

Humans possess great capacity for behavioral and cultural change, but our ability to manage change is still limited. This article has two major objectives: first, to sketch a basic science of intentional change centered on evolution; second, to provide examples of intentional behavioral and cultural change from the applied behavioral sciences, which are largely unknown to the basic sciences community.All species have evolved mechanisms of phenotypic plasticity that enable them to respond adaptively to their environments. Some mechanisms of phenotypic plasticity (...) count as evolutionary processes in their own right. The human capacity for symbolic thought provides an inheritance system having the same kind of combinatorial diversity as does genetic recombination and antibody formation. Taking these propositions seriously allows an integration of major traditions within the basic behavioral sciences, such as behaviorism, social constructivism, social psychology, cognitive psychology, and evolutionary psychology, which are often isolated and even conceptualized as opposed to one another.The applied behavioral sciences include well-validated examples of successfully managing behavioral and cultural change at scales ranging from individuals to small groups to large populations. However, these examples are largely unknown beyond their disciplinary boundaries, for lack of a unifying theoretical framework. Viewed from an evolutionary perspective, they are examples of managing evolved mechanisms of phenotypic plasticity, including open-ended processes of variation and selection.Once the many branches of the basic and applied behavioral sciences become conceptually unified, we are closer to a science of intentional change than one might think.

We present a conceptual framework on the experience of time and provide a coherent basis on which to base further inquiries into qualitative approaches concerning time experience. We propose two Time-Layers and two Time-Formats forming four Time-Domains. Micro-Flow and Micro-Structure represent the implicit phenomenal basis, from which the explicit experiences of Macro-Flow and Macro-Structure emerge. Complementary to this theoretical proposal, we present empirical results from qualitative content analysis obtained from 25 healthy participants. The data essentially corroborate the theoretical proposal. With (...) respect to Flow, the phenomenally accessible time experience appeared as a continuous passage reaching from the past through the present into the future. With respect to Structure, the individual present was embedded in the individual biography, emerging from past experiences and comprising individual plans and goals. New or changing plans and goals were being integrated into the existing present, thus forming a new present. The future appeared as changeable within the present, by means from the past, and therefore as a space of potential opportunities. Exemplarily, we discuss these results in relation to previous empirical findings on deviant experiences of time in Autism Spectrum Disorder that is presumably characterized by a breakdown of Flow and concomitant compensatory repetition resulting in an overly structured time. Finally, we speculate about possible implications of these findings both for psychopathological and neuroscientific research. (shrink)

David Schweickart moves beyond the familiar arguments against globalizing capitalism to contribute something absolutely necessary and long overdue—a coherent vision of a viable, desirable alternative to capitalism. He names this system Economic Democracy, a successor-system to capitalism which preserves the efficiency strengths of a market economy while extending democracy to the workplace and to the structures of investment finance. Drawing on both theoretical and empirical research, Schweickart shows how and why this model is efficient, dynamic, and superior to capitalism (...) along a range of values. (shrink)

Psychologists take two propositions for granted. Specifically, empirical verification of predictions derived from a theory support that the theory is more likely to be true and support that additional predictions derived from the theory have an increased probability of being sustained if subjected to empirical testing. In contrast, I argue that both propositions depend strongly on whether auxiliary assumptions are taken into account. When auxiliary assumptions are not taken into account, the first proposition is valid but the second is not. (...) When auxiliary assumptions are taken into account, the first proposition is not valid, and the second proposition encounters additional problems.

According to the somatic mutation theory (SMT), cancer begins with a genetic change in a single cell that passes it on to its progeny, thereby generating a clone of malignant cells. It is strongly supported by observations of leukemias that bear specific chromosome translocations, such as Burkitt's lymphoma, in which a translocation activates the c‐myc gene, and chronic myeloid leukemia (CML), in which the Philadelphia chromosome causes production of the BCR‐ABL oncoprotein. Although the SMT has been modified and extended to (...) encompass tumor suppressor genes, epigenetic inheritance, and tumor progression through accumulation of further mutations, perhaps the strongest validation comes from the successful treatment of certain malignancies with drugs that directly target the product of the mutant gene.magnified imageDavid Vaux is at the Walter and Eliza Hall Institute and La Trobe Institute for Molecular Science, Melbourne, Australia.

I argue that the metaphysical import of the Aharonov-Bohm effect has been overstated: correctly understood, it does not require either rejection of gauge invariance or any novel form of nonlocality. The conclusion that it does require one or the other follows from a failure to keep track, in the analysis, of the complex scalar field to which the magnetic vector potential is coupled. Once this is recognised, the way is clear to a local account of the ontology of electrodynamics ; (...) I sketch a possible such account. (shrink)

The bulk of this volume consists of a somewhat revised version of the Axel Hägerström Lectures given in Uppsala, Sweden in 1991. It also contains previously published papers on the relevance of philosophy of language to ethics and the interpretation of Kant’s moral philosophy. The latter, in particular, deserves comment, but space considerations force me to devote my attention to the Hägerström Lectures, entitled “A Taxonomy of Ethical Theories.”.

The early 20th-century French sociologist and philosopher Gabriel Tarde was an important critic of Durkheim's ontology of the social. Tarde developed a microsociological and ontological critique of the philosophical problems of resemblance and of variation underlying Durkheim's comparative sociology. Recently, thinkers such as Gilles Deleuze, Bruno Latour and Éric Alliez have begun to revisit Tarde and to develop a theme of the significance of Tarde's thought as a harbinger of postmodern theory. This article examines Tarde's theories in the light of (...) this new reception. It is shown that Tarde draws heavily from Leibniz's theory of the quantitative continuity of qualitative singulars in order to critique Durkheim's statistics-based social realism. While some key limitations of Tarde's critique are exposed, it is argued that Tarde finds a way to remain faithful to statistical sociology as a project even while calling radically into question the qualitative unity of the social.

When patients are admitted to the hospital, they are generally expected to remain in or within close proximity to their assigned rooms in order to promote their safety and appropriate medical care. Although there are circumstances when patients may safely leave their hospital room or floor, guidance within the medical literature for the management of patient movement within the hospital are lacking. Excessive restrictions on patient movement may be seen as overly paternalistic, while lax requirements may interfere with high quality (...) care, patient safety and efficient hospital practice. As a result, guidance in the form of institutional policy is warranted. Such policy development should take into consideration the potential clinical, legal, and ethical concerns in balancing the competing values of patients’ preferences and respect for autonomy, while ensuring high quality, safe, and efficacious medical care. This paper will provide a framework for hospitals to create institution-specific patient movement policies that are fair, systematic, and transparent. (shrink)

The reflections recorded in this paper arise from three moments in the theory of definition and of conceptual analysis. The moments are: Frege’s review of Husserl’s Philosophy of Arithmetic, the discussion there of the paradox of analysis, and the division that Frege marks, ensuing upon his distinction of Sinn/sense from Bedeutung/reference, between two different conceptions of definition; Leibniz’s still serviceable account of a distinction between the clarity and the distinctness of ideas---a distinction that prompts the suggestion that the guiding purpose (...) of lexical definition is Leibnizian clarity whereas that of real definition is inseparable from the pursuit of Leibnizian distinctness; Leibniz’s speculations concerning the limit or terminus of analysis. The apparent failure of these speculations, casting doubt as it does upon the aspirations that give rise to them, points to the long-standing need to reconfigure the philosophical business of enquiry into concepts.

If the discovery of life elsewhere in the universe is just around the corner, what would be the consequences for religion? Would it represent another major conflict between science and religion, even leading to the death of faith? Some would suggest that the discovery of any suggestion of extraterrestrial life would have a greater impact than even the Copernican and Darwinian revolutions. It is now over 50 years since the first modern scientific papers were published on the search for extraterrestrial (...) intelligence. Yet the religious implications of this search and possible discovery have never been systematically addressed in the scientific or theological arena. SETI is now entering its most important era of scientific development. New observation techniques are leading to the discovery of extra-solar planets daily, and the Kepler mission has already collected over 1000 planetary candidates. This deluge of data is transforming the scientific and popular view of the existence of extraterrestrial intelligence. Earth-like planets outside of our solar system can now be identified and searched for signs of life. Now is a crucial time to assess the scientific and theological questions behind this search. This book sets out the scientific arguments undergirding SETI, with particular attention to the uncertainties in arguments and the strength of the data already assembled. It assesses not only the discovery of planets but other areas such as the Fermi paradox, the origin and evolution of intelligent life, and current SETI strategies. In all of this it reflects on how these questions are shaped by history and pop culture and their relationship with religion, especially Christian theology. It is argued that theologians need to take seriously SETI and to examine some central doctrines such as creation, incarnation, revelation, and salvation in the light of the possibility of extraterrestrial life.

In his thoughtful defence of very modest moral enhancement, David DeGrazia1 makes the following assumption: ‘Behavioural improvement is highly desirable in the interest of making the world a better place and securing better lives for human beings and other sentient beings’. Later in the paper, he gives a list of some psychological characteristics that ‘all reasonable people can agree … represent moral defects’. I think I am a reasonable person, and I agree that most if not all items on (...) the lists do represent moral defects—I certainly would regard them as such in a close family member or friend. But if I were in the business of ‘making the world a better place and securing better lives for human beings and other sentient beings’, I would hesitate to prescribe moral enhancement for everyone with these acknowledged defects. A lot of good work, from removing tumours to negotiating treaties, may be best done by people with serious moral defects.For a simple consequentialist, a moral defect is just a trait that tends to make the world a worse place. Not being a consequentialist, I think that moral defects should be identified independently of their tendency to produce worse outcomes. For this reason, I think it's necessary to qualify DeGrazia's starting assumption—I think behavioural improvement may sometimes be undesirable if our goal is to make the world a better place. My reasons will be familiar to readers of Bernard Williams.As …. (shrink)

Fragments of Modernity provides a critical introduction to the work of three of the most original German thinkers of the early 20th century. In their different ways, all three illuminated the experience of the modern in urban life, whether in mid-19th-century Paris or in Berlin at the turn of the century or later as the vanguard city of the Weimar Republic. They related the new modes of experiencing the world to the maturation of the money economy (Simmel), the process of (...) rationalization of capital (Kracauer), and the fantasy world of commodity fetishism (Benjamin) - in each case focusing on those fragments of social experience that could best capture the sense of modernity.David Frisby is Reader in Sociology at Glasgow University.

Army Officers face increased moral pressure in modern warfare, where character judgement and ethical judgement are vital. This article reports the results of a study of 242 junior British Army officers using the Army Intermediate Concept Measure, comprising a series of professionally oriented moral dilemmas developed for the UK context. Results are suggestive of appropriate application of Army values to the dilemmas and of ethical reasoning aligning with Army excellence. The sample does slightly less well, however, for justification than for (...) action reasoning, and there are differences following initial training for infantry and artillery officers versus other branches of service. Dilemmas involving anti-torture methods and not covering up soldiers' failings generated best results compared to those requiring balance between compassion and mission, and negotiating personal relationships with military needs. Gender differences favouring women were less than those observed for other professional groups using similar measures. This research further develops a much-needed measure of ethical reasoning among junior Army officers, with potential for use among other ranks. This approach is advocated for other professional groups. (shrink)

David Miller explores and develops Michael Walzer's notion of complex equality as a way of bringing together the potentially conflicting ideas of distributive justice and social equality. He examines the empirical plausibility of the notion of complex equality and argues that Walzer's theory of the spheres of justice allows the construction of an understanding of distributive justice and social equality that is different from, and superior to, mainstream political philosophy.

A full range of sources is drawn upon and the reader can follow the fascinating story of Marx's marriage and family life amid extraordinary privations, his activities in the Communist League and the First International, and the ful extent and subtlety of his thought as it developed.

David Hume is, arguably, the most important philosopher ever to have written in English. Although best known for his contributions to epistemology, metaphysics, and the philosophy of religion, Hume also made substantial and influential contributions to psychology and the philosophy of mind, ethics, the philosophy of science, political and economic theory, political and social history, and, to a lesser extent, aesthetic and literary theory. All facets of Hume's output are discussed in this volume, the first genuinely comprehensive overview of (...) his work. The picture that emerges is of a thinker who, though critical to the point of scepticism, was nonetheless able to build on that scepticism a profoundly important, and still viable, constructive philosophy.

Objective Gather information from physicians about factors contributing to unnecessary noninvasive imaging and impact of possible solutions. Methods Qualitative study of 14 physicians using a phenomenological approach and the Theoretical Domains Framework. Results Most participants self-reported that >10% of the imaging tests they order are unnecessary. External sources of pressure included: peer-review, patient demands, nursing expectations, specialist requests, as well as prior experience with patient advocates, and the compensation and pension system. Internal sources of pressure included reliance on anecdote, self-doubt (...) about diagnoses, and fear of missing a diagnosis and of professional liability. Participants expressed both optimism and concern about potential solutions, such as adopting decision support software. Conclusion Physicians are under pressure from multiple sources to order unnecessary imaging. Peer review, nursing expectations, and perceptions about Veteran compensation and pension are newly reported contributing factors. (shrink)

abstract Many people assume that invasive research on animals is justified because of its supposed benefits and because of the supposed mental inferiority of animals. However probably most people would be unwilling to sign a living will which consigns themselves to live biomed‐ical experimentation if they ever, through misfortune, end up with a mental capacity equivalent to a laboratory animal. The benefits would be greater by far for medical science if living will signatories were to be used, and also the (...) mental superiority boast would no longer apply. Ultimately, it is argued that invasive biomedical experiments would be unacceptable in a democratic society whose members are philosophically self‐consistent. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Rhetoric 36.3 (2003) 177-188 [Access article in PDF] Chaïm Perelman's "First Philosophies and Regressive Philosophy":Commentary and Translation David A. Frank Michelle K. Bolduc Chaïm Perelman's 1949 article, "First Philosophies and Regressive Philosophy," has remained unavailable to readers unable to read French. Our commentary and translation is intended to provide English readers access to the context, influences, and themes that make the article an extraordinarily important work (...) in the history of twentieth-century rhetoric. In this article, Perelman offers a powerful critique of first philosophies and anticipates the problems of radical postmodernity. "First Philosophies" remains a strikingly elegant attempt to foil what Foucault (1984, 41-42) has called the "Enlightenment blackmail of reason," the assumption held by logical positivists and radical skeptics that if reason does not yield absolute and eternal Enlightenment knowledge, there can be no knowledge.Perelman and Lucie Olbrechts-Tyteca's New Rhetoric project avoids Enlightenment blackmail by charting a third way between logical positivism and radical relativism, and "First Philosophies" sets forth the project's philosophical blueprint. Commencing in 1947 and culminating in 1958 with the publication of Traité de l'argumentation: La nouvelle rhétorique, Perelman and Olbrechts-Tyteca sought, discovered, and developed a philosophical system designed as a rapprochement between dialectic (reason and logic) and rhetoric (the art of adapting arguments to audiences). Historians of rhetoric judge the work a "grand revolution" (Meyer 1999, 259), believing it marks a rhetorical renaissance in Europe, and suggest nothing like it will appear for another 100 years after its publication (Johnstone 1971). The New Rhetoric project influenced Gadamer and a host of post-war European and American thinkers (Mootz 1998). Michael Leff calls the 1970 English translation of Traité a "bombshell" (1994, 510). Beyond its historical importance, Crosswhite suggests that the New Rhetoric project is "the single most important event in contemporary rhetorical theory" (1996, 35)and "First Philosophies" marks Perelman's turn from logical [End Page 177] positivism to rhetoric, offering prescient answers to the post-World War II crises of reason, and the ideas in the article provide the Traité'sphilosophical glue (see in particular the English translation, 62).Perelman joined many post-war theorists, including Horkheimer and Adorno (1972), in the resistance to the reign of a disembodied Enlightenment rationality. However, Perelman identified what Habermas (1987, 119) would later call the "performative contradiction" in the conclusion that radical skepticism was the only alternative to Enlightenment rationality. In "First Philosophies," Perelman responds directly to Sartre's 1943 Being and Nothingness (198; see translation below) by exposing the failure of radical skeptics to see that they had been held hostage by Enlightenment blackmail in accepting the Enlightenment criterion for truth, rejecting it, and then making skepticism an absolute. Indeed, "First Philosophies" navigates from this performative contradiction to chart a third way between Enlightenment rationality and radical skepticism with an approach that he labels regressive philosophy. Regressive philosophy, Perelman argues, provides the human community with a mode of philosophical reasoning located between the extremes of Enlightenment rationality and radical skepticism. In this space between extremes, Perelman identifies contingent truths and values dependent on a rhetorical mode of reasoning, one making moral judgments possible.To best understand "First Philosophies," we recognize the importance of historical context in the development of social theories of knowledge (see Delacampagne 1999; Kennedy 1999). The intellectual networks in which philosophers operate also influence the development of philosophical systems, as Randall Collins has aptly documented. In addition to historical context and intellectual networks, Frederick Beiser has recently noted: "[t] he best introduction to any philosophy is the biography of the person who created it" (1999, 5). He argues that textual analysis alone cannot illuminate the motivation or meaning of a philosophy. A sense of Perelman's biography and the cultural influences that gave rise to "First Philosophies" are necessary for a proper understanding of its themes. For Perelman, the primary intellectual exigencies of the post-war period were the interrelated crises of justice, philosophical reasoning, and responsibility to which "First Philosophies" is a...

Early in this volume, David Ehrenfeld describes what prophecy really is. Referring to the biblical prophets, he says they were not the "holy fortunetellers that the word prophet has come to signify....The business of prophecy is not simply foretelling the future; rather it is describing the present with exceptional truthfulness and accuracy." Once this is done, then it can be seen that broad aspects of the future have suddenly become apparent. The twentieth century is drawing to a chaotic close (...) amidst portents of unprecedented change and upheaval. The unravelling of societies and civilizations and the destruction of nature march together--linked--a fact whose enormous significance is often lost. In Beginning Again, David Ehrenfeld has undertaken the difficult task of describing the present clearly enough to reveal the future. Out of his broad vision emerges a glimpse of a new millennium: a vision at once frightening and comforting, a scene of great devastation and great rebuilding. Ehrenfeld ranges far and wide to present a coherent vision of our relationship with Nature--its many aspects and implications--as our century opens into the next millennium. Whether he is writing about the problem of loyalty to organizations, rights versus obligations, our over-managed society, the vanishing of established knowledge, the failure of experts, the triumph of dandelions, Dr. Seuss, Edward Teller, or the future of farming, he is always concerned with the intricate interaction between technology and nature. As in his classic book, The Arrogance of Humanism, Ehrenfeld never loses sight of our fatal love affair with the fantasy of control. We now have no choice, he argues, but to transform the dream of control, of progress, from one of overweening hubris, love of consumption, and the idiot's goal of perpetual growth, to one based on "the inventive imitation of nature," with its honesty, beauty, resilience, and durability. Few American writers and even fewer scientists can describe these timeless, transcendent qualities of nature so well. In "Places," the opening chapter, David Ehrenfeld tells about nightly vigils he spent alone on the moonlit beach of Tortuguero, watching giant sea turtles emerging from the sea to lay their eggs in the black sand where they were born. "I could watch the perfect white spheres falling," he writes. "Falling as they have fallen for a hundred million years, with the same slow cadence, always shielded from the rain or stars by the same massive bulk with the beaked head and the same large, myopic eyes rimmed with crusts of sand washed out by tears. Minutes and hours, days and months dissolve into eons. I am on an Oligocene beach, an Eocene beach, a Cretaceous beach--the scene is the same. It is night, the turtles are coming back, always back; I hear a deep hiss of breath and catch a glint of wet shell as the continents slide and crash, the oceans form and grow.". (shrink)

Receiving social support from community and extended family has been typical for mothers with infants in human societies past and present. In non-industrialised contexts, infants of mothers with extended family support often have better health and higher survival through the vulnerable infant period, and hence shared infant care has a clear fitness benefit. However, there is scant evidence that these benefits continue in industrialised contexts. Better infant health and development with allocare support would indicate continued evolutionary selection for allocare. The (...) research reported here used multiple logistic regression analysis to test whether a lack of family and other social support for mothers was associated with an increased risk of developmental delay in 9-month-old infants in the UK Millennium Cohort (analysis sample size, 15,696 infants). Extended family-based childcare during work hours and more maternal time spent with friends were the most influential kin and social support variables: infants of mothers with kin-based childcare versus all other childcare arrangements had a lower risk of developmental delay (OR = 0.61, 95% CIs: 0.46–0.82). Infants of mothers who spent no time with friends when compared with those who saw friends every day had double the odds of delay. Greater paternal involvement in infant care was associated with a lower odds of developmental delay. In conclusion, shared care of infants and social support for mothers may influence fitness-related traits in industrialised societies rather than being factors that influenced selection only in the past and in societies which retain close kin networks and a strong local community focus.
