Recent research has shown that a phase transformation of diamond to a different form of carbon is involved when diamonds are polished in the traditional fashion. The question as to how this phase transformation is activated and maintained to produce high wear rates is of great technological interest since it may radically change the way we view the processing of diamond. This paper describes the use of Raman spectroscopy to examine debris produced on the diamond polishing wheel, both during its (...) preparation and during polishing. In addition, polished diamond surfaces were examined for the possible existence of non-diamond surface layers in an attempt to identify material removal mechanisms. Raman spectroscopy proves ideal for these analyses because its relatively high spatial resolution is well suited to the analysis of small wear features and debris particles, and because of the wealth of information it reveals about chemical structure. This level of structural information has been lacking in previous analyses of diamond polishing debris. In addition to the non-diamond carbon found in the wear debris, significant quantities of two iron oxides, magnetite (Fe3O4) and haematite (α-Fe2O3), were also found. An interesting observation was that a transformation from magnetite to haematite could be induced either by using high power laser excitation or by frictional heating during polishing. It is suggested that some of the Raman peaks previously attributed to lonsdaleite might better be explained by the presence of these oxides. (shrink)

This article seeks to situate pharmacological cognitive enhancement as part of a broader relationship between cultural understandings of the body-brain and the political economy. It is the body of the worker that forms the intersection of this relationship and through which it comes to be enacted and experienced. In this article, we investigate the imaginaries that both inform and are reproduced by representations of pharmacological cognitive enhancement, drawing on cultural sources such as newspaper articles and films, policy documents, and pharmaceutical (...) marketing material to illustrate our argument. Through analysis of these diverse cultural sources, we argue that the use of pharmaceuticals has come to be seen not only as a way to manage our brains, but through this as a means to manage our productive selves, and thereby to better manage the economy. We develop three analytical themes. First, we consider the cultural representations of the brain in connection with the idea of plasticity – captured most graphically in images of morphing – and the representation of enhancement as a desirable, inevitable, and almost painless process in which the mind-brain realizes its full potential and asserts its will over matter. Following this, we explore the social value accorded to productive employment and the contemporary ethos of working on or managing oneself, particularly in respect of improving one’s productive performance through cognitive enhancement. Developing this, we elaborate a third theme by looking at the moulding of the worker’s productive body-brain in relation to the demands of the economic system. (shrink)

The two dogmas at issue are the Humean dogma that “‘is’ statements do not imply ‘ought’ statements” and the Kantian dogma that “‘ought’ statements imply ‘can’” statements. The extant literature concludes these logically contradict each other. On the contrary, it is argued here that while there is no derivable formal contradiction, the juxtaposition of the dogmas manifests a philosophical disagreement over how to understand the logic of prescriptions. This disagreement bears on how to understand current metaethical debate between realists and (...) non-realists about morality in a way not heretofore investigated. The conclusion is that realists have the resources to account for both dogmas, while non-realists, if they strictly adhere to the “is”/“ought” gap, cannot give an adequate account of why “ought” implies “can”.

After the setbacks suffered in the 1970s as a result of the ‘Lighthill Report’ (Lighthill, 1973), the science of Artificial Intelligence (AI) has undergone a dramatic revival of fortunes in the 1980s. But despite the obvious enormity and complexity of the problems tackled by AI, it still remains rather parochial in relation to the import of alternative though potentially fruitful ideas from other disciplines. With this in mind, the aim of the present paper is to utilise ideas from the sociology (...) of science in order to explore some current issues in AI and, in particular, the branch of expert systems.It is argued that the sociology of sciences shares a common focus of enquiry along with AI — namely, the nature of knowledge — and has a role to play in the understanding, design and future development of expert systems.

For many, the very idea of an artificialintelligence has always been ethicallytroublesome. The putative ability of machinesto mimic human intelligence appears to callinto question the stability of taken forgranted boundaries between subject/object,identity/similarity, free will/determinism,reality/simulation, etc. The artificiallyintelligent object thus appears to threaten thehuman subject with displacement and redundancy.This article takes as its starting point AlanTuring''s famous ''imitation game,'' (the socalled ''Turing Test''), here treated as aparable of the encounter between human originaland machine copy – the born and the made. Thecultural (...) resonances of the recent on-lineperformance of a ''Turing Test'' for computergenerated art are then explored. Arttraditionally taken to stand for all that isconsidered quintessentially human – andtherefore resistant to mechanisation –represents in this sense a kind of ''criticalcase'' in the advance of machine intelligence.The article focuses on the moral status of thebody, human agency, and social knowledge in theongoing (re-)constructions of copy, original,and of the difference between them.

This is the first book to offer the best essays, articles, and speeches on ethics and intelligence that demonstrate the complex moral dilemmas in intelligence collection, analysis, and operations. Some are recently declassified and never before published, and all are written by authors whose backgrounds are as varied as their insights, including Robert M. Gates, former Director of the Central Intelligence Agency; John P. Langan, the Joseph Cardinal Bernardin Professor of Catholic Social Thought at the Kennedy Institute of Ethics, Georgetown (...) University; and Loch K. Johnson, Regents Professor of Political Science at the University of Georgia and recipient of the Owens Award for contributions to the understanding of U.S. intelligence activities. Creating the foundation for the study of ethics and intelligence by filling in the gap between warfare and philosophy, this is a valuable collection of literature for building an ethical code that is not dependent on any specific agency, department, or country.

Miller's reply to Nelson misses the point because it does not attend to the difference between identifying the truth conditions for a proposition and explaining why those conditions are the ones in which the proposition is true.

The volume will act as a useful collection of scholarship by top figures, and as a resource and course book on an important topic.

We explored the relationship between qualities of victims in hypothetical scenarios and the appearance of framing effects. In past studies, participants’ feelings about the victims have been demonstrated to affect whether framing effects appear, but this relationship has not been directly examined. In the present study, we examined the relationship between caring about the people at risk, the perceived interdependence of the people at risk, and frame. Scenarios were presented that differed in the degree to which participants could be expected (...) to care about the group and the extent to which the group could be construed as interdependent. A framing effect was found only for the scenario describing the victims as the participants’ friends who did not know each other (high caring/low interdependence), and this went in the opposite direction from typical framing effects. Finally, perceived interdependence and caring affected choice both within and across scenarios, with more risky choices made by participants with high interdependence ratings and high caring ratings.

Over recent decades International Relations scholars have investigated norm dynamics processes at some length, with the norm entrepreneur concept having become a common reference point in the literature. The focus on norm entrepreneurs has, however, resulted in a bias towards investigating the agents and processes of successful normative change. This book challenges this inherent bias by explicitly focusing on those who resist normative change - norm antipreneurs. The utility of the norm antipreneur concept is explored through a series of case (...) studies encompassing a range of issue areas and contributed by a mix of well-known and emergent scholars of norm dynamics. In examining the complexity of norm resistance, particular attention is paid to the nature and intent of the actors involved in norm-contestation, the sites and processes of resistance, the strategies and tactics antipreneurs deploy to defend the values and interests they perceive to be threatened by the entrepreneurs, and whether it is the entrepreneurs or the antipreneurs who enjoy greater inherent advantages. This text will therefore be of interest to scholars and students of International Relations, International Law, Political Science, Sociology and History. ". (shrink)

Morality seems to play a special role in human life distinct from conventional norms, like those of etiquette, or simple preferences based on subjective tastes. There are various theories of the foundations of morality, some of which treat morality as 'subjective' in an important way. 'Moral realism' is however a family of theories that take morality to have an objective factual basis, such that morality is not 'up to us' and is not 'under our control'. The contributions in this handbook (...) explore the central ideas and themes constituting moral realism and defend particular views about it. (shrink)

It is the foundation of all traditional and modern analyses of Sanskrit, as well as having great historical and theoretical interest in its own right. Western grammatical theory has been influenced by it at every stage of its development for the last two centuries. The early 19th century comparativists learned from it the principles of morphological analysis. Bloomfield modeled both his classic Algonquian grammars and the logical-positivist axiomatization of his Postulates on it. Modern linguistics acknowledges it as the most (...) complete generative grammar of any language yet written, and continues to adopt technical ideas from it. (shrink)

The question “Why is it bad to be bad?” might seem either tautologous or poorly formed. It may seem like a tautology because it seems logical to think that badness is necessarily bad and so it must, of course, follow that it is bad to be bad. It might seem to be malformed because it may seem like anyone who asks the question, “Why is it bad to be bad?” must fail to understand the meaning of the words they are (...) using: generally, if something is X, it cannot fail to be X. If so, then it may seem as if there must be something wrong with the question itself or with the linguistic abilities of the person asking it. The inclusion of “all things considered” is crucial. Some think that there is a problem with the idea of an all-things-considered point of view since it seems to them that the plurality of values one attempts to bring together in a single perspective may be incommensurable, so there is a problem in the idea of engaging such a perspective.

Many experiments with infants suggest that they possess quantitative abilities, and many experimentalists believe that these abilities set the stage for later mathematics: natural numbers and arithmetic. However, the connection between these early and later skills is far from obvious. We evaluate two possible routes to mathematics and argue that neither is sufficient: (1) We first sketch what we think is the most likely model for infant abilities in this domain, and we examine proposals for extrapolating the natural number concept (...) from these beginnings. Proposals for arriving at natural number by (empirical) induction presuppose the mathematical concepts they seek to explain. Moreover, standard experimental tests for children's understanding of number terms do not necessarily tap these concepts. (2) True concepts of number do appear, however, when children are able to understand generalizations over all numbers; for example, the principle of additive commutativity (a+b=b+a). Theories of how children learn such principles usually rely on a process of mapping from physical object groupings. But both experimental results and theoretical considerations imply that direct mapping is insufficient for acquiring these principles. We suggest instead that children may arrive at natural numbers and arithmetic in a more top-down way, by constructing mathematical schemas. (shrink)

There is little more common in ethics than to think pain is intrinsically bad and pleasure is intrinsically good. A Humean-style error theory of the axiology of pain and pleasure is developed against these commonsense claims. We defend the thesis that the value of pain and pleasure is always contingent and only instrumental. We survey prominent theories of both intrinsic value and pain/pleasure, all of which assume that pain and pleasure are intrinsically valuable. We base our error theory on counterexamples (...) to this assumption, upon which these theories falter, and a theory of pain and pleasure which derives their value solely from their evolutionary function.

The incredible achievements of modern scientific theories lead most of us to embrace scientific realism: the view that our best theories offer us at least roughly accurate descriptions of otherwise inaccessible parts of the world like genes, atoms, and the big bang. In Exceeding Our Grasp, Stanford argues that careful attention to the history of scientific investigation invites a challenge to this view that is not well represented in contemporary debates about the nature of the scientific enterprise. The historical record (...) of scientific inquiry, Stanford suggests, is characterized by what he calls the problem of unconceived alternatives. Past scientists have routinely failed even to conceive of alternatives to their own theories and lines of theoretical investigation, alternatives that were both well-confirmed by the evidence available at the time and sufficiently serious as to be ultimately accepted by later scientific communities. Stanford supports this claim with a detailed investigation of the mid-to-late 19th century theories of inheritance and generation proposed in turn by Charles Darwin, Francis Galton, and August Weismann. He goes on to argue that this historical pattern strongly suggests that there are equally well-confirmed and scientifically serious alternatives to our own best theories that remain currently unconceived. Moreover, this challenge is more serious than those rooted in either the so-called pessimistic induction or the underdetermination of theories by evidence, in part because existing realist responses to these latter challenges offer no relief from the problem of unconceived alternatives itself. Stanford concludes by investigating what positive account of the spectacularly successful edifice of modern theoretical science remains open to us if we accept that our best scientific theories are powerful conceptual tools for accomplishing our practical goals, but abandon the view that the descriptions of the world around us that they offer are therefore even probably or approximately true.

persusasions are in addition impressed by its remarkable conciseness, and by the rigorous consistency with which it deploys its semi-formalized metalanguage, a grammatically and lexically regimented form of Sanskrit. Empiricists like Bloomfield also admired it for another, more specific reason, namely that it is based on nothing but very general principles such as simplicity, without prior commitments to any scheme of “universal grammar”, or so it seems, and proceeds from a strictly synchronic perspective. Generative linguists for their part have (...) marveled especially at its ingenious technical devices, and at intricate system of conventions governing rule application and rule interaction that it presupposes, which seem to uncannily anticipate ideas of modern linguistic theory (if only because many of them were originally borrowed from P¯.

Some scientific categories seem to correspond to genuine features of the world and are indispensable for successful science in some domain; in short, they are natural kinds.

By the time of his death in 2006, Sir Peter Strawson was regarded as one of the world's most distinguished philosophers. Unavailable for many years,_ Scepticism and Naturalism_ is a profound reflection on two classic philosophical problems by a philosopher at the pinnacle of his career. Based on his acclaimed Woodbridge lectures delivered at Columbia University in 1983, Strawson begins with a discussion of scepticism, which he defines as questioning the adequacy of our grounds for holding various beliefs. He then (...) draws deftly on Hume and Wittgenstein to argue that we must distinguish between 'hard', scientific naturalism; or 'soft', humanistic naturalism. In the remaining chapters the author takes up several issues in which sceptical doubts play an important role, in particular the nature of transcendental arguments and including the objectivity of moral philosophy, the mental and the physical, and the existence of abstract entities. _Scepticism and Naturalism_ is essential reading for those seeking an introduction to the work of one of the twentieth century’s most important and original philosophers. This reissue includes a substantial new foreword by Quassim Cassam and a fascinating intellectual autobiography by Strawson, which together form an excellent introduction to his life and work.

We typically assume that the standard for what is beautiful lies in the eye of the beholder. Yet this is not the case when we consider morality; what we deem morally good is not usually a matter of opinion. Such thoughts push us toward being realists about moral properties, but a cogent theory of moral realism has long been an elusive philosophical goal. Paul Bloomfield here offers a rigorous defense of moral realism, developing an ontology for morality that models (...) the property of being morally good on the property of being physically healthy. The model is assembled systematically; it first presents the metaphysics of healthiness and goodness, then explains our epistemic access to properties such as these, adds a complementary analysis of the semantics and syntax of moral discourse, and finishes with a discussion of how we become motivated to act morally. Bloomfield closely attends to the traditional challenges facing moral realism, and the discussion nimbly ranges from modern medical theory to ancient theories of virtue, and from animal navigation to the nature of normativity. Maintaining a highly readable style throughout, Moral Reality yields one of the most compelling theories of moral realism to date and will appeal to philosophers working on issues in metaphysics or moral philosophy.

The concept of normal is so familiar that it can be hard to imagine contemporary life without it. Yet the term entered everyday speech only in the mid-twentieth century. Before that, it was solely a scientific term used primarily in medicine to refer to a general state of health and the orderly function of organs. But beginning in the middle of the twentieth century, normal broke out of scientific usage, becoming less precise and coming to mean a balanced condition to (...) be maintained and an ideal to be achieved. In Normality, Peter Cryle and Elizabeth Stephens offer an intellectual and cultural history of what it means to be normal. They explore the history of how communities settle on any one definition of the norm, along the way analyzing a fascinating series of case studies in fields as remote as anatomy, statistics, criminal anthropology, sociology, and eugenics. Cryle and Stephens argue that since the idea of normality is so central to contemporary disability, gender, race, and sexuality studies, scholars in these fields must first have a better understanding of the context for normality. This pioneering book moves beyond binaries to explore for the first time what it does—and doesn’t—mean to be normal. (shrink)

Traditional theories of how children learn the positive integers start from infants' abilities in detecting the quantity of physical objects. Our target article examined this view and found no plausible accounts of such development. Most of our commentators appear to agree that no adequate developmental theory is presently available, but they attempt to hold onto a role for early enumeration. Although some defend the traditional theories, others introduce new basic quantitative abilities, new methods of transformation, or new types of end (...) states. A survey of these proposals, however, shows that they do not succeed in bridging the gap to knowledge of the integers. We suggest that a better theory depends on starting with primitives that are inherently structural and mathematical. (shrink)
