This work-in-progress paper consists of four points which relate to the foundations and physical realization of quantum computing. The first point is that the qubit cannot be taken as the basic unit for quantum computing, because not every superposition of bit-strings of length n can be factored into a string of n-qubits. The second point is that the “No-cloning” theorem does not apply to the copying of one quantum register into another register, because the mathematical representation of this copying is (...) the identity operator, which is manifestly linear. The third point is that quantum parallelism is not destroyed only by environmental decoherence. There are two other forms of decoherence, which we call measurement decoherence and internal decoherence, that can also destroy quantum parallelism. The fourth point is that processing the contents of a quantum register “one qubit at a time” destroys entanglement. (shrink)

To what extent should parents be allowed to use reproductive technologies to determine the characteristics of their future children? Is there something morally wrong with choosing what their sex will be, or with trying to 'screen out' as much disease and disability as possible before birth? Stephen Wilkinson offers answers to such questions.

When we speak, we mean more than we say. In this book Stephen C. Levinson explains some general processes that underlie presumptions in communication.

Zoos and animal rights seem utterly opposed to each other. In this controversial and timely book, Stephen Bostock argues that they can develop a more harmonious relationship. He examines the diverse ethical and technical issues involved, including human cruelty, human domination over animals, the well-being of wild animals outside their natural habitat, and the nature of wild and domestic animals. In his analysis, Bostock draws attention to the areas which give rise to misconceptions. This book explores the long history (...) of zoos, as well as current philosophical debates, to argue for a conservational view of their role in the modern world. Anyone concerned with humanity's relationship with other animals and the natural world will find this to be thought-provoking and rewarding reading. (shrink)

In the seventeenth century, a vision arose which was to captivate the Western imagination for the next three hundred years: the vision of Cosmopolis, a society as rationally ordered as the Newtonian view of nature. While fueling extraordinary advances in all fields of human endeavor, this vision perpetuated a hidden yet persistent agenda: the delusion that human nature and society could be fitted into precise and manageable rational categories. Stephen Toulmin confronts that agenda—its illusions and its consequences for our (...) present and future world. "By showing how different the last three centuries would have been if Montaigne, rather than Descartes, had been taken as a starting point, Toulmin helps destroy the illusion that the Cartesian quest for certainty is intrinsic to the nature of science or philosophy."—Richard M. Rorty, University of Virginia "[Toulmin] has now tackled perhaps his most ambitious theme of all.... His aim is nothing less than to lay before us an account of both the origins and the prospects of our distinctively modern world. By charting the evolution of modernity, he hopes to show us what intellectual posture we ought to adopt as we confront the coming millennium."—Quentin Skinner, New York Review of Books. (shrink)

There is a trend toward the use of predictive systems in communications networks. At the systems and network management level predictive capabilities are focused on anticipating network faults and performance degradation. Simultaneously, mobile communication networks are being developed with predictive location and tracking mechanisms. The interactions and synergies between these systems present a new set of problems. A new predictive network management framework is developed and examined. The interaction between a predictive mobile network and the proposed network management system is (...) discussed. The Rapidly Deployable Radio Network is used as a specific example to illustrate these interactions. (shrink)

In this work, which has survived only in manuscript form and in Italian, Gardiner analyses the great dynastic changes in England's past in order to provide Phillip II with a guide to ruling England and establishing a Catholic dynasty. Gardiner's work is perhaps the clearest example of an attempt to relate Machiavelli's political theories to practical political problems.

_Bodies for Sale: Ethics and Exploitation in the Human Body Trade _explores the philosophical and practical issues raised by activities such as surrogacy and organ trafficking. Stephen Wilkinson asks what is it that makes some commercial uses of the body controversial, whether the arguments against commercial exploitation stand up, and whether legislation outlawing such practices is really justified. In Part One Wilkinson explains and analyses some of the notoriously slippery concepts used in the body commodification debate, including exploitation, harm (...) and consent. In Part Two he focuses on three controversial issues outlining contemporary regulation and investigating both the moral issues and the arguments for legal prohibition. (shrink)

In light of many recent critiques of Western modernity and its conceptual foundations, the problem of adequately justifying our most basic moral and political values looms large. Without recourse to traditional ontological or metaphysical foundations, how can one affirm — or sustain — a commitment to fundamentals? The answer, according to Stephen White, lies in a turn to “weak” ontology, an approach that allows for ultimate commitments but at the same time acknowledges their historical, contestable character. This turn, White (...) suggests, is already underway. His book traces its emergence in a variety of quarters in political thought today and offers a clear and compelling account of what this might mean for our late modern self-understanding. (shrink)

In The Things We Mean I argue that there exist such things as the things we mean and believe, and that they are what I call pleonastic propositions. The first two chapters offer an initial motivation and articulation of the theory of pleonastic propositions, and of pleonastic entities generally. The remaining six chapters bring that theory to bear on issues in the theory of content: the existence and nature of meanings; knowledge of meaning; the meaning relation and compositional semantics; the (...) relation between content-involving facts and underlying physical facts; vagueness and indeterminacy; conditionals; normative discourse; and the role of propositional content in explanation, prediction, and knowledge acquisition.

I critically examine the semantic view of theories to reveal the following results. First, models in science are not the same as models in mathematics, as holders of the semantic view claim. Second, when several examples of the semantic approach are examined in detail no common thread is found between them, except their close attention to the details of model building in each particular science. These results lead me to propose a deflationary semantic view, which is simply that model construction (...) is an important component of theorizing in science. This deflationary view is consistent with a naturalized approach to the philosophy of science. (shrink)

Our knowledge of the world comes from various sources. But it is sometimes said that testimony, unlike other sources, transmits knowledge from one person to another. In this book, Stephen Wright investigates what the transmission of knowledge involves and the role that it should play in our theorising about testimony as a source of knowledge. He argues that the transmission of knowledge should be understood in terms of the more fundamental concept of the transmission of epistemic grounds, and that (...) the claim that testimony transmits knowledge is not only defensible in its own right, but indispensable to an adequate theory of testimony. This makes testimony unlike other epistemic sources. (shrink)

The concept of "practices"—whether of representation, of political or scientific traditions, or of organizational culture—is central to social theory. In this book, Stephen Turner presents the first analysis and critique of the idea of practice as it has developed in the various theoretical traditions of the social sciences and the humanities. Understood broadly as a tacit understanding "shared" by a group, the concept of a practice has a fatal difficulty, Turner argues: there is no plausible mechanism by which a (...) "practice" is transmitted or reproduced. The historical uses of the concept, from Durkheim to Kripke's version of Wittgenstein, provide examples of the contortions that thinkers have been forced into by this problem, and show the ultimate implausibility of the idea. Turner's conclusion sketches a picture of what happens when we do without the notion of a shared practice, and how this bears on social theory and philosophy. It explains why social theory cannot get beyond the stage of constructing fuzzy analogies, and why the standard constructions of the contemporary philosophical problem of relativism depend upon this defective notion. This first book-length critique of practice theory is sure to stir discussion and controversy in a wide range of fields, from philosophy and science studies to sociology, anthropology, literary studies, and political and legal theory.

The core niche for language use is in verbal interaction, involving the rapid exchange of turns at talking. This paper reviews the extensive literature about this system, adding new statistical analyses of behavioral data where they have been missing, demonstrating that turn-taking has the systematic properties originally noted by Sacks et al. (1974 ; hereafter SSJ). This system poses some significant puzzles for current theories of language processing: the gaps between turns are short (of the order of 200 ms), but (...) the latencies involved in language production are much longer (over 600 ms). This seems to imply that participants in conversation must predict (or ‘project’ as SSJ have it) the end of the current speaker’s turn in order to prepare their response in advance. This in turn implies some overlap between production and comprehension despite their use of common processing resources. Collecting together what is known behaviorally and experimentally about the system, the space for systematic explanations of language processing for conversation can be significantly narrowed, and we sketch some first model of the mental processes involved for the participant preparing to speak next.

Kant holds that the human cognitive power is divided into two "stems", understanding and sensibility. This doctrine has seemed objectionably dualistic to many critics, who see these stems as distinct parts, each able on its own to produce representations, which must somehow interact, determining or constraining one another, in order to secure the fit, requisite for cognition, between concept and intuition. This reading cannot be squared, however, with what Kant actually says about theoretical cognition and the way understanding and sensibility (...) cooperate in it. Such cognition, as Kant conceives of it, satisfies two conditions: it has unity, and it depends on the existence of its object. The first of these conditions entails that the cognitive power must lie in spontaneity, or understanding, while the second implies that this spontaneity depends on receptivity, or sensibility, to be the cognitive power that it is. Consideration of how these capacities must be conceived as cooperating in cognition reveals them to be related, not as interacting parts, but as form and matter. Such a conception of their relation may at first glance seem to be merely another version of dualistic thinking; in fact, however, a proper appreciation of it eliminates the appearance of dualism and helps allay an associated concern that Kant's distinction would taint our cognition with an unacceptable subjectivism.

Scientific pluralism is an issue at the forefront of philosophy of science. This landmark work addresses the question, Can pluralism be advanced as a general, philosophical interpretation of science? Scientific Pluralism demonstrates the viability of the view that some phenomena require multiple accounts. Pluralists observe that scientists present various—sometimes even incompatible—models of the world and argue that this is due to the complexity of the world and representational limitations. Including investigations in biology, physics, economics, psychology, and mathematics, this work provides (...) an empirical basis for a consistent stance on pluralism and makes the case that it should change the ways that philosophers, historians, and social scientists analyze scientific knowledge.

Since 2000, 11 human uterine transplantation procedures (UTx) have been performed across Europe and Asia. Five of these have, to date, resulted in pregnancy and four live births have now been recorded. The most significant obstacles to the availability of UTx are presently scientific and technical, relating to the safety and efficacy of the procedure itself. However, if and when such obstacles are overcome, the most likely barriers to its availability will be social and financial in nature, relating in particular (...) to the ability and willingness of patients, insurers or the state to pay. Thus, publicly funded healthcare systems such as the UK9s National Health Service (NHS) will eventually have to decide whether UTx should be funded. With this in mind, we seek to provide an answer to the question of whether there exist any compelling reasons for the state not to fund UTx. The paper proceeds as follows. It assumes, at least for the sake of argument, that UTx will become sufficiently safe and cost-effective to be a candidate for funding and then asks, given that, what objections to funding there might be. Three main arguments are considered and ultimately rejected as providing insufficient reason to withhold funding for UTx. The first two are broad in their scope and offer an opportunity to reflect on wider issues about funding for infertility treatment in general. The third is narrower in scope and could, in certain forms, apply to UTx but not other assisted reproductive technologies (ARTs). The first argument suggests that UTx should not be publicly funded because doing so would be inconsistent with governments’ obligations to prevent climate change and environmental pollution. The second claims that UTx does not treat a disorder and is not medically necessary. Finally, the third asserts that funding for UTx should be denied because of the availability of alternatives such as adoption and surrogacy. (shrink)

The Value of Life is an exploration of the actual and perceived importance of biological diversity for human beings and society. Stephen R. Kellert identifies ten basic values, which he describes as biologically based, inherent human tendencies that are greatly influenced and moderated by culture, learning, and experience. Drawing on 20 years of original research, he considers: the universal basis for how humans value nature differences in those values by gender, age, ethnicity, occupation, and geographic location how environment-related activities (...) affect values variation in values relating to different species how vlaues vary across cultures policy and management implications Throughout the book, Kellert argues that the preservation of biodiversity is fundamentally linked to human well-being in the largest sense as he illustrates the importance of biological diversity to the human sociocultural and psychological condition.

Fisher’s 1918 paper accomplished two distinct goals: unifying discrete Mendelian genetics with continuous biometric phenotypes and quantifying the variance components of variation in complex human characteristics. The former contributed to the foundation of modern quantitative genetics; the latter was adopted by social scientists interested in the pursuit of Galtonian nature-nurture questions about the biological and social origins of human behavior, especially human intelligence. This historical divergence has produced competing notions of the estimation of variance ratios referred to as heritability. Jay (...) Lush showed that they could be applied to selective breeding on the farm, while the early twin geneticists used them as a descriptive statistic to describe the degree of genetic determination in complex human traits. Here we trace the early history of the heritability coefficient now used by social scientists. (shrink)

Arguing About Human Nature covers recent debates--arising from biology, philosophy, psychology, and physical anthropology--that together systematically examine what it means to be human. Thirty-five essays--several of them appearing here for the first time in print--were carefully selected to offer competing perspectives on 12 different topics related to human nature. The context and main threads of the debates are highlighted and explained by the editors in a short, clear introduction to each of the 12 topics. Authors include Louise Anthony, Patrick Bateson, (...) David Buller, John Dupre, Paul Griffiths, Sally Haslanger, Richard Lewontin, Ron Mallon, and E.O. Wilson. Contributors Rachel Cooper, Nancy Holmstrom, Kim Sterelny, and Elizabeth Cashdan provide brand new chapters in these debates. Suggested Reading lists offer curious readers new resources for exploring these debates further. A rguing About Human Nature is the first volume of its kind, designed to introduce to an interdisciplinary student audience some of the most important arguments on the subject generated by scientific research and philosophical reflection.

In just a few years, children achieve a stable state of linguistic competence, making them effectively adults with respect to: understanding novel sentences, discerning relations of paraphrase and entailment, acceptability judgments, etc. One familiar account of the language acquisition process treats it as an induction problem of the sort that arises in any domain where the knowledge achieved is logically underdetermined by experience. This view highlights the cues that are available in the input to children, as well as childrens skills (...) in extracting relevant information and forming generalizations on the basis of the data they receive. Nativists, on the other hand, contend that language-learners project beyond their experience in ways that the input does not even suggest. Instead of viewing language acqusition as a special case of theory induction, nativists posit a Universal Grammar, with innately specified linguistic principles of grammar formation. The nature versus nurture debate continues, as various poverty of stimulus arguments are challenged or supported by developments in linguistic theory and by findings from psycholinguistic investigations of child language. In light of some recent challenges to nativism, we rehearse old poverty-of stimulus arguments, and supplement them by drawing on more recent work in linguistic theory and studies of child language.

This essay responds to Hirstein, Sifferd and Fagan’s book, Responsible Brains, which claims that executive function is the guiding mechanism that supports both responsible agency and the necessity for some excuses. In contrast, I suggest that executive function is not the universal acid and the neuroscience at present contributes almost nothing to the necessary psychological level of explanation and analysis. To the extent neuroscience can be useful, it is virtually entirely dependent on well-validated psychology to correlate with the neuroscientific variables (...) under investigation. The essay considers what executive function is and what the neuroscience adds to our understanding of it. Then it addresses moral and legal responsibility generally, and specific doctrines. Executive function is seldom found to be the most perspicuous approach to any of the general or specific moral and legal questions. (shrink)

One widely held view of prenatal screening is that its foremost aim is, or should be, to enable reproductive choice; this is the Pure Choice view. The article critiques this position by comparing it with an alternative: Public Health Pluralism. It is argued that there are good reasons to prefer the latter, including the following. Public Health Pluralism does not, as is often supposed, render PNS more vulnerable to eugenics-objections. The Pure Choice view, if followed through to its logical conclusions, (...) may have unpalatable implications, such as extending choice well beyond health screening. Any sensible version of Public Health Pluralism will be capable of taking on board the moral seriousness of abortion and will advocate, where practicable, alternative means of reducing the prevalence of disease and disability. Public Health Pluralism is at least as well-equipped as the Pure Choice model to deal with autonomy and consent issues. (shrink)

In a world where every person is exposed daily through the mass media to images of violence and suffering, as most dramatically exemplified in recent years by the ongoing tragedy in Darfur, the question naturally arises: What responsibilities do we, as bystanders to such social injustice, bear in holding accountable those who have created the conditions for this suffering? And what is our own complicity in the continuance of such violence—indeed, how do we contribute to and benefit from it? How (...) is our responsibility as individuals connected to our collective responsibility as members of a society? Such questions underlie Stephen Esquith’s investigation in this book. For Esquith, being responsible means holding ourselves accountable as a people for the institutions we have built or tolerated and the choices we have made individually and collectively within these institutional constraints. It is thus more than just acknowledgment; it involves settling accounts as well as recognizing our own complicity even as bystanders. (shrink)

The Limits of Influence is a detailed examination and defense of the evidence for largescale-psychokinesis.

Science and the End of Ethics examines some of the most important positive and negative implications that science has for ethics. Addressing the negative implications first, author Stephen Morris discusses how contemporary science provides significant challenges to moral realism. One threat against moral realism comes from evolutionary theory, which suggests that our moral beliefs are unconnected to any facts that would make them true. Ironically, many of the same areas of science (e.g. evolutionary biology, neuroscience, psychology) that present difficulties (...) for moral realism point to a new ethical approach that focuses on achieving some of the key practical goals shared by ethicists. Chief among these is how to increase amicable behavior among people. (shrink)

Biologists, climate scientists, and economists all rely on models to move their work forward. In this book, I explore the use of models in these and other fields to introduce readers to the various philosophical issues that arise in scientific modeling. I show that paying attention to models plays a crucial role in appraising scientific work. -/- After surveying a wide range of models from a number of different scientific disciplines, I demonstrate how focusing on models sheds light on many (...) perennial issues in philosophy of science and in philosophy in general. For example, reviewing the range of views on how models represent their targets introduces readers to the key issues in debates on representation, not only in science but in the arts as well. Also, standard epistemological questions are cast in new and interesting ways when we confront the question, "What makes for a good (or bad) model?". (shrink)

Leslie Stephen (1832–1904) was a writer, philosopher and literary critic whose work was published widely in the nineteenth century. As a young man Stephen was ordained deacon, but he later became agnostic and much of his work reflects his interest in challenging popular religion. This two-volume work, first published in 1876, is no exception: it focuses on the eighteenth-century deist controversy and its effects, as well as the reactions to what Stephen saw as a revolution in thought. (...) Comprehensive and full of detailed analysis, this is an important work in the history of ideas. Volume 2 focuses on eighteenth-century moral philosophy, political philosophy and literature, and on the literary and religious reactions to the revolution in thought. Utilitarianism is discussed at length, as well as the work of thinkers such as Shaftesbury, Mandeville, Burke and Adam Smith. (shrink)

What happens to scientific knowledge when researchers outside the natural sciences bring elements of the latest trend across disciplinary boundaries for their own purposes? Researchers in fields from anthropology to family therapy and traffic planning employ the concepts, methods, and results of chaos theory to harness the disciplinary prestige of the natural sciences, to motivate methodological change or conceptual reorganization within their home discipline, and to justify public policies and aesthetic judgments. Using the recent explosion in the use of chaos (...) theory, _Borrowed Knowledge and the Challenge of Learning across Disciplines _examines the relationship between science and other disciplines as well as the place of scientific knowledge within our broader culture. Stephen H. Kellert’s detailed investigation of the myriad uses of chaos theory reveals serious problems that can arise in the interchange between science and other knowledge-making pursuits, as well as opportunities for constructive interchange. By engaging with recent debates about interdisciplinary research, Kellert contributes a theoretical vocabulary and a set of critical frameworks for the rigorous examination of borrowing. (shrink)
