The occurrence of oscillatory behaviours in living cells can be viewed as a visible consequence of stable, regulatory homeostatic cycles. Therefore, they may be used as experimental windows on the underlying physiological mechanisms. Recent studies show that growing pollen tubes are an excellent biological model for these purposes. They unite experimental simplicity with clear oscillatory patterns of both structural and temporal features, most being measurable during real‐time in live cells. There is evidence that these cellular oscillators involve an integrated input (...) of plasma membrane ion fluxes, and a cytosolic choreography of protons, calcium and, most likely, potassium and chloride. In turn, these can create positive feedback regulation loops that are able to generate and self‐sustain a number of spatial and temporal patterns. Other features, including cell wall assembly and rheology, turgor, and the cytoskeleton, play important roles and are targets or modulators of ion dynamics. Many of these features have similarities with other cell types, notably with apical‐growing cells. Pollen tubes may thus serve as a powerful model for exploring the basis of cell growth and morphogenesis. BioEssays 23:86–94, 2001. © 2001 John Wiley & Sons, Inc. (shrink)

Violence in schools is a pervasive, highly emotive and, above all, global problem. Bullying and its negative social consequences are of perennial concern, while the media regularly highlights incidences of violent assault - and even murder - occurring within schools. This unique and fascinating text offers a comprehensive overview and analysis of how European nations are tackling this serious issue. _Violence in Schools: The Response in Europe_, brings together contributions from all EU member states and two associated states. Each chapter (...) begins by clearly outlining the nature of the school violence situation in that country. It then goes on to describe those social policy initiatives and methods of intervention being used to address violence in schools and evaluates the effectiveness of these different strategies. Commentaries from Australia, Israel and the USA and an overview of the book's main themes by eminent psychologist Peter K. Smith complete a truly international and authoritative look at this important - and frequently controversial - subject. This book constitutes an invaluable resource for educational administrators, policymakers and researchers concerned with investigating, and ultimately addressing, the social and psychological causes, manifestations and effects of school violence.

In these challenging pages, Unger argues for the extreme skeptical view that, not only can nothing ever be known, but no one can ever have any reason at all for anything. A consequence of this is that we cannot ever have any emotions about anything: no one can ever be happy or sad about anything. Finally, in this reduction to absurdity of virtually all our supposed thought, he argues that no one can ever believe, or even say, that anything is (...) the case. (shrink)

By contributing a few hundred dollars to a charity like UNICEF, a prosperous person can ensure that fewer poor children die, and that more will live reasonably long, worthwhile lives. Even when knowing this, however, most people send nothing, and almost all of the rest send little. What is the moral status of this behavior? To such common cases of letting die, our untutored response is that, while it is not very good, neither is the conduct wrong. What is the (...) source of this lenient assessment? In this contentious new book, one of our leading philosophers argues that our intuitions about ethical cases are generated not by basic moral values, but by certain distracting psychological dispositions that all too often prevent us from reacting in accord with our commitments. Through a detailed look at how these tendencies operate, Unger shows that, on the good morality that we already accept, the fatally unhelpful behavior is monstrously wrong. By uncovering the eminently sensible ethics that we've already embraced fully, and by confronting us with empirical facts and with easily followed instructions for lessening serious suffering appropriately and effectively, Unger's book points the way to a compassionate new moral philosophy.

The topic of personal identity has prompted some of the liveliest and most interesting debates in recent philosophy. In a fascinating new contribution to the discussion, Peter Unger presents a psychologically aimed, but physically based, account of our identity over time. While supporting the account, he explains why many influential contemporary philosophers have underrated the importance of physical continuity to our survival, casting a new light on the work of Lewis, Nagel, Nozick, Parfit, Perry, Shoemaker, and others. Deriving from (...) his discussion of our identity itself, Unger produces a novel but commonsensical theory of the relations between identity and some of our deepest concerns. In a conservative but flexible spirit, he explores the implications of his theory for questions of value and of the good life. (shrink)

Play takes up much of the time budget of young children, and many animals, but its importance in development remains contested. This comprehensive collection brings together multidisciplinary and developmental perspectives on the forms and functions of play in animals, children in different societies, and through the lifespan. The Cambridge Handbook of Play covers the evolution of play in animals, especially mammals; the development of play from infancy through childhood and into adulthood; historical and anthropological perspectives on play; theories and methodologies; (...) the role of play in children's learning; play in special groups such as children with impairments, or suffering political violence; and the practical applications of playwork and play therapy. Written by an international team of scholars from diverse disciplines such as psychology, education, neuroscience, sociology, evolutionary biology and anthropology, this essential reference presents the current state of the field in play research.

During the middle of the twentieth century, philosophers generally agreed that, by contrast with science, philosophy should offer no substantial thoughts about the general nature of concrete reality. Instead, philosophers offered conceptual truths. It is widely assumed that, since 1970, things have changed greatly.

This bold and original work of philosophy presents an exciting new picture of concrete reality. Peter Unger provocatively breaks with what he terms the conservatism of present-day philosophy, and returns to central themes from Descartes, Locke, Berkeley, Hume and Russell. Wiping the slate clean, Unger works, from the ground up, to formulate a new metaphysic capable of accommodating our distinctly human perspective. He proposes a world with inherently powerful particulars of two basic sorts: one mental but not physical, the (...) other physical but not mental. Whether of one sort or the other, each individual possesses powers for determining his or her own course, as well as powers for interaction with other individuals. It is only a purely mental particular--an immaterial soul, like yourself--that is ever fit for real choosing, or for conscious experiencing. Rigorously reasoning that the only satisfactory metaphysic is one that situates the physical alongside the non-physical, Unger carefully explains the genesis of, and continual interaction of, the two sides of our deeply dualistic world. Written in an accessible and entertaining style, while advancing philosophical scholarship, All the Power in the World takes readers on a philosophical journey into the nature of reality. In this riveting intellectual adventure, Unger reveals the need for an entirely novel approach to the nature of physical reality--and shows how this approach can lead to wholly unexpected possibilities, including disembodied human existence for billions of years. All the Power in the World returns philosophy to its most ambitious roots in its fearless attempt to answer profoundly difficult human questions about ourselves and our world. (shrink)

In this short but meaty book, Peter Unger questions the objective answers that have been given to central problems in philosophy. As Unger hypothesizes, many of these problems are unanswerable, including the problems of knowledge and scepticism, the problems of free will, and problems of causation and explanation. In each case, he argues, we arrive at one answer only relative to an assumption about the meaning of key terms, terms like "know" and like "cause," even while we arrive at (...) an opposite answer relative to quite different assumptions, but equally arbitrary assumptions, about what the key terms mean.

Wittgenstein’s remarks on Frazer’s The Golden Bough were first edited and published in 1967 by Rush Rhees as Wittgenstein’s Bemerkungen über Frazers ‘The Golden Bough’. However, there is another edition, called Ludwig Wittgenstein: Remarks on Frazer’s Anthropology, edited and translated by Kenneth Laine Ketner and James Leroy Eigsti. In this paper I outline at least part of the history of this edition. At the same time, I shall describe some of the characteristic features of the Ketner and Eigsti edition. This (...) presentation takes as its point of departure the correspondence contained in the box “Wittgenstein 143” at the von Wright and Wittgenstein Archives, consisting of twelve letters that passed between Ketner and Eigsti, G.E.M. Anscombe, Rhees, and G.H. von Wright in 1972 and 1973. The presentation will also indirectly throw light on a number of issues concerning the editorial principles applied in publishing Wittgenstein’s remarks. (shrink)

This paper outlines an interpretation of Ludwig Wittgenstein’s remark in the _Big Typescript_ in which he compares the philosopher bewitched by the workings of language to “the suffering of an ascetic”. The interpretation takes as its starting point Friedrich Nietzsche’s terse account of the philosopher, the history of philosophy, and his diagnosis of ascetic self-misunderstanding, from the Third Essay, “What do ascetic ideals mean?”, in _On the Genealogy of Morality_. In its assumption of an affinity between Wittgenstein’s remark and Nietzsche’s (...) descriptions, and in its analysis, this paper introduces a “method of voice borrowing” to approach the question: “Wittgenstein and Nietzsche?” The juxtaposition of Wittgenstein’s conception of the philosopher’s linguistic self-misunderstanding with Nietzsche’s notion of the ascetic self-misunderstanding leads finally to the question of what is gained by introducing this method, and hence by reading Wittgenstein’s remark on the suffering of an ascetic with the help of Nietzsche’s voice.

Few people, if any, still argue that science in all its aspects is a value-free endeavor. At the very least, values affect decisions about the choice of research problems to investigate and the uses to which the results of research are applied. But what about the actual doing of science? -/- As Science, Values, and Objectivity reveals, the connections and interactions between values and science are quite complex. The essays in this volume identify the crucial values that play a role (...) in science, distinguish some of the criteria that can be used for value identification, and elaborate the conditions for warranting certain values as necessary or central to the very activity of scientific research. -/- Recently, social constructivists have taken the presence of values within the scientific model to question the basis of objectivity. However, the contributors to <I>Science, Values, and Objectivity</I> recognize that such acknowledgment of the role of values does not negate the fact that objects exist in the world. Objects have the power to constrain our actions and thoughts, though the norms for these thoughts lie in the public, social world. -/- Values may be decried or defended, praised or blamed, but in a world that strives for a modicum of reason, values, too, must be reasoned. Critical assessment of the values that play a role in scientific research is as much a part of doing good science as interpreting data. (shrink)

This volume presentsa definitive introduction to the core areas of philosophy of science.

Traditionally it has been thought that scientific controversies can always be resolved on the basis of empirical data. Recently, however, social constructionists have claimed that the outcome of scientific debates is strongly influenced by non-evidential factors such as the rhetorical prowess and professional clout of the participants. This volume of previously unpublished essays by well-known philosophers of science presents historical studies and philosophical analyses that undermine the plausibility of an extreme social constructionist perspective while also indicating the need for a (...) richer and more realistic account of scientific rationality.

The current research applied a mid-level evolutionary theory that has been successfully employed across numerous animal species—life history theory—in an attempt to understand the Dark Triad personality trait cluster (narcissism, psychopathy, and Machiavellianism). In Study 1 (N = 246), a measure of life history strategy was correlated with psychopathy, but unexpectedly with neither Machiavellianism nor narcissism. Study 2 (N = 321) replicated this overall pattern of results using longer, traditional measures of the Dark Triad traits and alternative, future-discounting indicators of (...) life history strategy (a smaller-sooner, larger-later monetary dilemma and self-reported risk-taking behaviors). Additional findings suggested two sources of shared variance across the Dark Triad traits: confidence in predicting future outcomes and openness to short-term mating. (shrink)

This is the first book to focus on Descartes's changing views, and it is welcome."--Roger Ariew, University of South Florida.

In this paper I suggest that play is a distinctive behavioural category whose adaptive significance calls for explanation. Play primarily affords juveniles practice toward the exercise of later skills. Its benefits exceed its costs when sufficient practice would otherwise be unlikely or unsafe, as is particularly true with physical skills and socially competitive ones. Manipulative play with objects is a byproduct of increased intelligence, specifically selected for only in a few advanced primates, notably the chimpanzee.The adaptiveness of play in pongid (...) evolution is traced through the probable changes in selective pressures that occurred in hominid evolution. It is argued that fantasy was an emergent property in hominids, made possible by symbolic intelligence and language, and serving to make play complex enough to continue to provide useful practice for increasingly complex later skills.The advent of organised instruction and education has meant that play's unplanned, intrinisic goal-setting could be replaced by extrinsic goal-setting in the systematic development of particular skills. However, the need to ensure adequate motivation has continued to give play educational value. In addition, its capacity to enhance innovative behaviour seems to be a residual function of play which has acquired a new cultural importance. (shrink)

A historical investigation of the exclusion of Africa and Asia from modern histories of philosophy.

This book is the only contemporary, systematic study of the relationship of time and conscious experience. Peter K. Mclnerney examines three tightly interconnected issues: how we are able to be conscious of time and temporal entities, whether time exists independently of conscious experience, and whether the conscious experiencer exists in time in the same way that ordinary natural objects are thought to exist in time. Insight is drawn from the views of major phenomenological and existential thinkers on these issues. (...) Building on a detailed explication and critique of the views of Kant, Husserl, Heidegger, and Sartre, Mclnerney develops and defends his own positions. He argues that a revised version of Husserl’s three-feature theory of time-consciousness provides the best explanation of our awareness of temporal features, but that an independently real time is necessary to explain our experience of temporal passage. He also shows that human existence has some special temporal features in addition to those it shares with other entities. Time-consciousness, the conscious exercise of powers, and personal identity through time require that any temporal part of human existence be defined by and "reach across" to earlier and later parts.

Courts and commentators have struggled for years to identify rules to explain and justify certain widely-shared intuitions about impossibility attempts, and they have proposed rules variously based upon (1) what mistakes actors make, (2) what intentions actors possess, and (3) what conduct actors perform. None of the proposals fully succeeds, however, and none is able to explain the widely-shared intuition, which underlies Sandy Kadish's inventive hypothetical regarding Mr. Law and Mr. Fact, that some attempts based upon mistakes of law are (...) just as blameworthy as attempts based upon mistakes of fact. I propose an alternative rule that, I believe, not only explains where and why people possess widely-shared intuitions regarding impossibility attempts (including regarding Mr. Law and Mr. Fact), but also explains where and why people have conflicting intuitions. I argue that widely-shared intuitions of blameworthiness and non-blameworthiness regarding impossibility attempts are a function, respectively, of whether informed citizens of the jurisdiction that enacted the statutory offense that the defendant allegedly attempted to commit widely believe or disbelieve that he would have been a threat to interests that the statute seeks to protect - a determination, in turn, that is a function of whether they widely believe or disbelieve that he would have committed the offense under counterfactual circumstances that they fear could have obtained.

For some fifty years now, nearly all work in mainstream analytic philosophy has made no serious attempt to understand the _nature of_ _physical reality,_ even though most analytic philosophers take this to be all of reality, or nearly all. While we've worried much about the nature of our own experiences and thoughts and languages, we've worried little about the nature of the vast physical world that, as we ourselves believe, has them all as only a small part.

In _The Metaphysics of Media_, award-winning media critic Peter K. Fallon tackles the complicated question of how a succession of dominant forms of media have supported—and even to some extent created—different conceptions of reality. To do so, he starts with the basics: a critical discussion of the very idea of objective reality and the various postmodern responses that have tended to dominate recent philosophical approaches to the subject. From there, he embarks on a survey of the evolution of communication (...) through four major eras: orality; literacy; print; and electricity. Within each era, Fallon argues, the dominant form of media supported particular ways of understanding the world, from the ascendance of reason that followed the development of alphabets to the obliteration of space and time that we associate with electronic communications. Fallon concludes with a hard look at the mass ignorance that prevails today despite the sea of information with which contemporary life is surrounded. A stirring, philosophically rich investigation, _The Metaphysics of Media_ offers not only a clear picture of where our society has been but also a road map to a more engaged, informed, and fully human future.

Emerging as a hot topic in the mid-twentieth century, causality is one of the most frequently discussed issues in contemporary philosophy. Thinking about Causes brings together top philosophers from the United States and Europe to focus on causality as a major force in philosophical and scientific thought.

Two prominent theoretical frameworks in moral psychology, Moral Foundations and Dual Process Theory, share a broad foundational assumption that individual differences in human morality are dispositional and in part due to genetic variation. The only published direct test of heritability, however, found little evidence of genetic influences on moral judgments using instrumentation approaches associated with Moral Foundations Theory. This raised questions about one of the core assumptions underpinning intuitionist theories of moral psychology. Here we examine the heritability of moral psychology (...) using the moral dilemmas approach commonly used in Dual Process Theory research. Using such measures, we find consistent and significant evidence of heritability. These findings have important implications not only for understanding which measures do, or do not, tap into the genetically influenced aspects of moral decision-making, but in better establishing the utility and validity of different intuitionist theoretical frameworks and the source of why people differ in those frameworks.

The various aesthetic phenomena found repeatedly in the scientific enterprise stem from the role of God as artist. If the Creator is an artist, how and why natural scientists study the divine art work can be understood using theological aesthetics and the philosophy of art. The aesthetic phenomena considered here are as follows. First, science reveals beauty and the sublime in natural phenomena. Second, science discovers beauty and the sublime in the theories that are developed to explain natural phenomena. Third, (...) the search for beauty often guides scientists in their work. Fourth, where beauty is perceived, feelings of the sublime often also follow upon further contemplation. This linkage of beauty in science with truth and the sublime runs counter to most aesthetic theory since Kant. Scholarship in theological aesthetics has recently argued that the modern and postmodern elevation of the sublime over beauty is merely a preference that reveals a bias against transcendence—against God. If doing and understanding science can show this sundering of the sublime from the beautiful to be in error, science also gives evidence of transcendence. (shrink)

He also employs this definition against certain materialists, but in what follows I wish only to address myself to the proposed definition.

I shall show that his definition is (...) too restrictive. (shrink)

While well-known for his book-length work, philosopher Peter Unger's articles have been less widely accessible. These two volumes of Unger's Philosophical Papers include articles spanning more than 35 years of Unger's long and fruitful career. Dividing the articles thematically, this first volume collects work in epistemology and ethics, among other topics, while the second volume focuses on metaphysics. Unger's work has advanced the full spectrum of topics at the heart of philosophy, including epistemology, metaphysics, philosophy of language and philosophy (...) of mind, and ethics. Unger advances radical positions, going against the so-called "commonsense philosophy" that has dominated the analytic tradition since its beginnings early in the twentieth century. In epistemology, his articles advance the view that nobody ever knows anything and, beyond that, argue that nobody has any reason to believe anything--and even beyond that, they argue that nobody has any reason to do anything, or even want anything. In metaphysics, his work argues that people do not really exist--and neither do puddles, plants, poodles, and planets. But, as Unger has often changed his favored positions, from one decade to the next, his work also advances the opposite, "commonsense" positions: that there are in fact plenty of people, puddles, plants and planets and, quite beyond that, we know it all to be true. On most major philosophical questions, both of these sides of Unger's significant work are well represented in this major two volume collection. Unger's vivid writing style, intellectual vitality, and fearlessness in the face of our largest philosophical questions, make these volumes of great interest not only to the philosophical community but to others who might otherwise find contemporary philosophy dry and technical.
