In this paper we argue that there are valuable consonances between democratic theory and music theory, and between democratization and musical performance and enjoyment. We suggest that this connection is not as trite as it may first appear, but that, since democracy is learned and practiced in a myriad ofways, music is one such place to learn democratic citizenship. The paper begins with a normative account of democratic theory that is present in two movements. The first, “foundations,” explicates the essential (...) components, criteria, and conditions of democracy. The second, “flows,” addresses the dynamism of democratization. Here is an account of what democracy looks like in action. We then turn to an explication of music theory and improvisation. Here, we focus on jazz as a way to hear the kind of interplay, responsiveness, accountability, discipline, and extemporaneousness that occurs in good jazz, and in authentic (radical) democracy.

Rob Clifton was one of the most brilliant and productive researchers in the foundations and philosophy of quantum theory, who died tragically at the age of 38. Jeremy Butterfield and Hans Halvorson collect fourteen of his finest papers here, drawn from the latter part of his career (1995-2002), all of which combine exciting philosophical discussion with rigorous mathematical results. Many of these papers break wholly new ground, either conceptually or technically. Others resolve a vague controversy intoa precise technical problem, (...) which is then solved; still others solve an open problem that had been in the air for soem time. All of them show scientific and philosophical creativity of a high order, genuinely among the very best work in the field. The papers are grouped into four Parts. First come four papers about the modal interpretation of quantum mechanics. Part II comprises three papers on the foundations of algebraic quantum field theory, with an emphasis on entanglement and nonlocality. The two papers in Part III concern the concept of a particle in relativistic quantum theories. One paper analyses localization; the other analyses the Unruh effect (Rindler quanta) using the algebraic approach to quantum theory. Finally, Part IV contains striking new results about such central issues as complementarity, Bohr's reply to the EPR argument, and no hidden variables theorems; and ends with a philosophical survey of the field of quantum information. The volume includes a full bibliography of Clifton's publications. Quantum Entanglements offers inspiration and substantial reward to graduates and professionals in the foundations of physics, with a background in philosophy, physics, or mathematics. (shrink)

I argue that the most promising approach to understanding J.J. Gibson's "affordances" takes affordances themselves as ontological primitives, instead of treating them as dispositional properties of more primitive things, events, surfaces, or substances. These latter are best treated as coalescences of affordances present in the environment (or "coalescences of use-potential," as in Sanders (1994) and Hilditch (1995)). On this view, even the ecological approach's stress on the complementary organism/environment pair is seen as expressing a particular affordance relation between the (...) world and the analyst. That the world is parsed in any way among events and objects, perceivers and worlds, etc., reflects equally features of certain real or possible perspectives on the world and features of the world itself. In section 1, I begin by contending that, contrary to the apparent expectations of some in the field, the bare existence of affordances is surely quite uncontroversial. In section 2, I argue that the most reasonable approach to foundational ontology is a relativistic one. In section 3, I address the claim that affordances must be ontologically complemented by effectivities for the sake of completeness, and I shall argue against that claim on grounds that I take to reflect some of Gibson's most important insights. This work will help to clarify the way affordances are to be used in the fourth and final section, where I argue that ontological work, even within special sciences, should not be merely "regional," and that the most attractive general approach to ontological questions is one that is based on affordances, rather than upon things, events, surfaces, and the like.

give a proof of the existence of nonlocal influences acting on correlated spin-1/2 particles in the singlet state which does not require any particular interpretation of quantum mechanics (QM). (Except Stapp holds that the proof fails under a many-worlds interpretation of QM—a claim we analyse in 1.2.) Recently, in responding to Redhead's ([1987], pp. 90-6) criticism that the Stapp 1 proof fails under an indeterministic interpretation of QM, Stapp [1989] (henceforth Stapp 2), has revised the logical structure of his proof (...) including its crucial locality assumption. Our main aim is to show that this revision is a step in the wrong direction because it faces two difficulties which undermine the resulting proof's significance (3.1) and validity (3. 2). We also clarify and extend the Stapp 1 proof (1. 1) with the aid of Lewis' analysis of counterfactuals (1. 2) and causal dependence (2. 2 and 2. 3). In so doing, we are able to identify two new defects in the Stapp 1 proof (1. 3 and 2. 1) in addition to corroborating Redhead's criticism (2. 2). Also, the additional assumptions which save the Stapp 1 proof's validity are detailed (2. 3) and some new difficulties for the determinist are pointed out by exploiting a slightly extended version of the proof (2. 4). In providing this full analysis of the Stapp 1 proof, we also construct the necessary framework within which to provide a critique of Stapp 2's proof (3). *Portions of this paper were presented by R. K. Clifton to the 1988 British Society for the Philosophy of Science Conference at the University of Southampton. R. K. Clifton wishes to thank the Natural Sciences and Engineering Research Council of Canada, the Royal Commission for the Exhibition of 1851, and the Governing Body of Peterhouse at Cambridge University for support during this work.

The centerpiece of Jeffrey Bub's book Interpreting the Quantum World is a theorem (Bub and Clifton 1996) which correlates each member of a large class of no-collapse interpretations with some 'privileged observable'. In particular, the Bub-Clifton theorem determines the unique maximal sublattice L(R,e) of propositions such that (a) elements of L(R,e) can be simultaneously determinate in state e, (b) L(R,e) contains the spectral projections of the privileged observable R, and (c) L(R,e) is picked out by R and e (...) alone. In this paper, we explore the issue of maximal determinate sets of observables using the tools provided by the algebraic approach to quantum theory; and we call the resulting algebras of determinate observables, "maximal *beable* subalgebras". The capstone of our exploration is a generalized version of Bub and Clifton's theorem that applies to arbitrary (i.e., both mixed and pure) quantum states, to Hilbert spaces of arbitrary (i.e., both finite and infinite) dimension, and to arbitrary observables (including those with a continuous spectrum). Moreover, in the special case covered by the original Bub-Clifton theorem, our theorem reproduces their result under strictly weaker assumptions. This added level of generality permits us to treat several topics that were beyond the reach of the original Bub-Clifton result. In particular: (a) We show explicitly that a (non-dynamical) version of the Bohm theory can be obtained by granting privileged status to the position observable. (b) We show that Clifton's (1995) characterization of the Kochen-Dieks modal interpretation is a corollary of our theorem in the special case when the density operator is taken as the privileged observable. (c) We show that the 'uniqueness' demonstrated by Bub and Clifton is only guaranteed in certain special cases -- viz., when the quantum state is pure, or if the privileged observable is compatible with the density operator. We also use our results to articulate a solid mathematical foundation for certain tenets of the orthodox Copenhagen interpretation of quantum theory. For example, the uncertainty principle asserts that there are strict limits on the precision with which we can know, simultaneously, the position and momentum of a quantum-mechanical particle. However, the Copenhagen interpretation of this fact is not simply that a precision momentum measurement necessarily and uncontrollably disturbs the value of position, and vice-versa; but that position and momentum can never in reality be thought of as simultaneously determinate. We provide warrant for this stronger 'indeterminacy principle' by showing that there is no quantum state that assigns a sharp value to both position and momentum; and, a fortiori, that it is mathematically impossible to construct a beable algebra that contains both the position observable and the momentum observable. We also prove a generalized version of the Bub-Clifton theorem that applies to "singular" states (i.e., states that arise from non-countably-additive probability measures, such as Dirac delta functions). This result allows us to provide a mathematically rigorous reconstruction of Bohr's response to the original EPR argument -- which makes use of a singular state. In particular, we show that if the position of the first particle is privileged (e.g., as Bohr would do in a position measuring context), the position of the second particle acquires a definite value by virtue of lying in the corresponding maximal beable subalgebra. But then (by the indeterminacy principle) the momentum of the second particle is not a beable; and EPR's argument for the simultaneous reality of both position and momentum is undercut. (shrink)

We show that the Bub-Clifton uniqueness theorem (1996) for 'no collapse' interpretations of quantum mechanics can be proved without the 'weak separability' assumption.

This introduction to a special Tradition and Discovery issue on Polanyi’s realism summarizes, and comments on the views of Jha, Gulick, Mullins, Cannon, Puddefoot, Meek and Sanders. All agree that Polanyi advocated a scientific realism hanging on the theses that reality is independent of human conceptualizations and that it is partially and fallibly knowable. Major differences concern its scope. All agree that it is comprehensive, pertaining not only to common sense and science but to intrinsic and ultimate values, and (...) perhaps the divine realities as well. Whereas Jha and Gulick argue a more limited scope, others defend a Polanyian position by drawing in various ways on the personal (Cannon) and social (Mullins, Sanders, Puddefoot) coefficients of the practice of inquiry. The debates show clearly that the relationship between Polanyi’s epistemology, axiology and hermeneutics deserve further scrutiny. (shrink)

John Taurek has argued that, where choices must be made between alternatives that affect different numbers of people, the numbers are not, by themselves, morally relevant. This is because we "must" take "losses-to" the persons into account (and these don't sum), but "must not" consider "losses-of" persons (because we must not treat persons like objects). I argue that the numbers are always ethically relevant, and that they may sometimes be the decisive consideration.

In a recent article in this journal, Richard Gale and Alexander Pruss offer a new cosmological proof for the existence of God relying only on the Weak Principle of Sufficient Reason, W-PSR. We argue that their proof relies on applications of W-PSR that cannot be justified, and that our modal intuitions simply do not support W-PSR in the way Gale and Pruss take them to.

In his recent article On Relativity Theory and Openness of the Future (1991), Howard Stein proves not only that one can define an objective becoming relation in Minkowski spacetime, but that there is only one possible definition available if one accepts certain natural assumptions about what it is for becoming to occur and for it to be objective. Stein uses the definition supplied by his proof to refute an argument due to Rietdijk (1966, 1976), Putnam (1967) and Maxwell (1985, 1988) (...) that Minkowski spacetime leaves no room for objective becoming whatsoever. However, Stein's proof does not seem to go far enough. By considering only what events have become from the standpoint of any given event, Stein's uniqueness proof fails from the outset to allow for a more general kind of becoming whereby it is understood to occur from the standpoint of events on the particular worldlines followed by observers. This suggests that there may, after all, be more than one way to define objective becoming in Minkowski spacetime once each observer's worldline is allowed to figure in the definition. This suspicion is further aroused by two recent proposals for objective, worldline-dependent becoming due to Peacock (1992) and Muller (1992) who advocate ways of defining becoming that are not equivalent to the definition Stein's uniqueness proof delivers. Nevertheless, we show that Stein's uniqueness proofcan be extended in a natural way to cover this more general kind of becoming, provided one does not enrich standard Minkowski spacetime by privileging certain sets of worldlines over others in an unwarranted manner. Thus we aim to reinforce Stein's point that standard Minkowski spacetime does make room for objective becoming, but in essentially only one way, despite arguments and proposals to the contrary.

My aim in this paper is a modest one. I do not have any particular thesis to advance about the nature of entanglement, nor can I claim novelty for any of the material I shall discuss. My aim is simply to raise some questions about entanglement that spring naturally from certain developments in quantum information theory and are, I believe, worthy of serious consideration by philosophers of science. The main topics I discuss are different manifestations of quantum nonlocality, entanglement-assisted communication, (...) and entanglement thermodynamics. (shrink)

This is a more detailed version of my "On 'Cuteness'", which appeared in the British Journal of Aesthetics in April 1992. For John Morreall, cuteness is an abstract general attribute of infants that causes adults to want to care for them (or which is the reason, or at least important reason, for such solicitousness). I shall try to show, in what follows, that this is, if not an altogether fallacious way of explaining the matter, at least an extremely misleading one. (...) As it stands, in particular, it is too easy to infer from Morreall's line of reasoning 1) that infants in general might conceivably never have developed cuteness, and 2) that infants, because of this deficiency, would then not be cared for as adequately by their parents. An equally wrong further implication, which further helps to express my difficulty with Morreall's formulation of the matter, would be that if baby spiders (for example) had happened to have the abstract general characteristic called 'cuteness', while human children did not have it, then human adults would have been more inclined to care for baby spiders than for baby humans. It is to avoid such oddities as these that, it seems to me, a further consideration of the problem is warranted. (shrink)

In Anarchy, State and Utopia, Robert Nozick argues, first, that free-market anarchism is unstable -that it will inevitably lead back to the state; and, second, that without a certain "redistributive" proviso, the model is unjust. If either of these things is the case, the model defeats itself, for its justification purports to be that it provides a morally acceptable alternative to government (and therefore to the state). I argue, against Nozick's contention, that his "dominant protection agency" neither meets his monopoly (...) condition for statehood nor need run afowl of his redistributive requirement. This being the case, his argument against free market anarchism fails. (shrink)

George Berkeley's apparently strange view – that nothing exists without a mind except for minds themselves – is notorious. Also well known, and equally perplexing at a superficial level, is his insistence that his doctrine is no more than what is consistent with common sense. It was every bit as crucial for Berkeley that it be demonstrated that the colors are really in the tulip, as that there is nothing that is neither a mind nor something perceived by a mind. (...) In what follows, I shall attempt to re-examine Berkeley's argument in terms of what it appears to have meant to him. I am especially interested in the connection between Berkeley's thought concerning the relation between perception and metaphysics and that of Maurice Merleau-Ponty, with whom, perhaps surprisingly, Berkeley shared a great many intuitions and concerns. Thus part of my objective is to compare and contrast the work of two thinkers who had many common interests, and whose thought frequently led them down similar paths. I shall be especially interested in apparent points of departure, both those that turn out to reflect real divergences and those which reflect confusions of one kind or another. My main objective, however, is not mere textual analysis. Like both Berkeley and Merleau-Ponty, my main hope is to make progress in clarifying how things are. As odd as some of Berkeley's pronouncements may sound to contemporary ears – concerning especially the metaphysical consequences of what he regarded as perceptual facts – I shall argue that, in substance, he was often not far wrong at all – at least as measured by important strands of more contemporary work on the subject. More particularly, I shall contend that for going a long way down an extraordinarily fruitful path which has been subsequently explored more fully by (especially) Martin Heidegger, Merleau-Ponty, Nelson Goodman and Hilary Putnam, Berkeley deserves considerably more credit than he is usually accorded as a progenitor of contemporary approaches to metaphysical issues.

Stanislaw Lesniewski’s interests were, for the most part, more philosophical than mathematical. Prior to taking his doctorate at Jan Kazimierz University in Lvov, Lesniewski had spent time at several continental universities, apparently becoming relatively attached to the philosophy of one of his teachers, Hans Comelius, to the chapters of John Stuart Mill’s System of Logic that dealt specifically with semantics, and, in general, to studies of general grammar and philosophy of language. In these several early interests are already to be (...) found the roots of the work that was to occupy Lesniewski’s life: a search for a definitive doctrine of what sorts of things there are in the world, or better, of what language must be like if it is adequately and efficiently to represent the world.

Harry Heft's Ecological Psychology in Context is an important book in many ways. For one thing, it adds considerably to our understanding of the historical background of J.J. Gibson's thought. But more than that, Heft aims to place ecological psychology not just historically, but philosophically. He says "This volume shows that radical empiricism stands at the heart of Gibson's ecological program, and it can usefully be employed as the conceptual centerpiece for ecological psychology more broadly construed" (p. xvi). While I (...) was impressed with Harry's argument to this effect, I'm not yet entirely persuaded. In these brief remarks I'll try to explain why. (shrink)

Entanglement has long been the subject of discussion by philosophers of quantum theory, and has recently come to play an essential role for physicists in their development of quantum information theory. In this paper we show how the formalism of algebraic quantum field theory (AQFT) provides a rigorous framework within which to analyse entanglement in the context of a fully relativistic formulation of quantum theory. What emerges from the analysis are new practical and theoretical limitations on an experimenter's ability to (...) perform operations on a field in one spacetime region that can disentangle its state from the state of the field in other spacelike-separated regions. These limitations show just how deeply entrenched entanglement is in relativistic quantum field theory, and yield a fresh perspective on the ways in which the theory differs conceptually from both standard non-relativistic quantum theory and classical relativistic field theory.

Artificial agents (AAs), particularly but not only those in Cyberspace, extend the class of entities that can be involved in moral situations. For they can be conceived of as moral patients (as entities that can be acted upon for good or evil) and also as moral agents (as entities that can perform actions, again for good or evil). In this paper, we clarify the concept of agent and go on to separate the concerns of morality and responsibility of agents (most (...) interestingly for us, of AAs). We conclude that there is substantial and important scope, particularly in Computer Ethics, for the concept of moral agent not necessarily exhibiting free will, mental states or responsibility. This complements the more traditional approach, common at least since Montaigne and Descartes, which considers whether or not (artificial) agents have mental states, feelings, emotions and so on. By focussing directly on mind-less morality we are able to avoid that question and also many of the concerns of Artificial Intelligence. A vital component in our approach is the Method of Abstraction for analysing the level of abstraction (LoA) at which an agent is considered to act. The LoA is determined by the way in which one chooses to describe, analyse and discuss a system and its context. The Method of Abstraction is explained in terms of an interface or set of features or observables at a given LoA. Agenthood, and in particular moral agenthood, depends on a LoA. Our guidelines for agenthood are: interactivity (response to stimulus by change of state), autonomy (ability to change state without stimulus) and adaptability (ability to change the transition rules by which state is changed) at a given LoA. Morality may be thought of as a threshold defined on the observables in the interface determining the LoA under consideration. An agent is morally good if its actions all respect that threshold; and it is morally evil if some action violates it. That view is particularly informative when the agent constitutes a software or digital system, and the observables are numerical. Finally we review the consequences for Computer Ethics of our approach. In conclusion, this approach facilitates the discussion of the morality of agents not only in Cyberspace but also in the biosphere, where animals can be considered moral agents without their having to display free will, emotions or mental states, and in social contexts, where systems like organizations can play the role of moral agents. The primary cost of this facility is the extension of the class of agents and moral agents to embrace AAs. (shrink)

If the term "relativism" is understood as relativists take it, everyone is a relativist. If, on the other hand, one understands "relativism" as absolutists do, no one really could consistently be a relativist, despite what they might think. As I hope to show, however, much of this positioning of persons and philosophies is foolish. It misses much that is important in philosophical discussion and focuses attention in directions that lead to dead ends.

My objective in this paper is to address a handful of issues that typically get raised in discussions of philosophical anarchism. Some of these issues arise in discussions among partisans of anarchism, and some are more likely to be raised in efforts to defend the state against its opponents. My hope is to focus the argument in such a way as to make clearer the main issues that are at stake from the point of view of at least one version (...) of philosophical anarchism. (shrink)

Cognitive science is ready for a major reconceptualization. This is not at all because efforts by its practitioners have failed, but rather because so much progress has been made. The need for reconceptualization arises from the fact that this progress has come at greater cost than necessary, largely because of more or less philosophical (at least metatheoretical) straightjackets still worn - whether wittingly or not - by those doing the work. These bonds are extremely hard to break. Even some of (...) those who have directed powerful arguments against them have failed entirely to shake them off. The bonds are often attributed to the work of René Descartes, but they are really much older than that. If even in the present effort, I fail entirely to remove the straightjacket myself (even though I am making every attempt to get it off), this will testify to its tight grip. The straightjacket I am thinking about, of course, is the vague picture of the human situation that imagines centralized, internal minds in control of bodily machines. While almost no one in the contemporary cognitive science arena imagines minds to be the kind of thing Descartes took them to be - instantiations of a unique, fully non-material substance - there is nevertheless a deep resistance, even among the most fervent professed "materialists," to giving up this picture. In what follows, I shall try to offer an approach which on the one hand capitalizes on the excellent progress that has been made in cognitive science in the last few decades, and which on the other hand offers a general approach that may help at some level in the attempt to shake "Cartesian" bonds. The approach, as the alert reader already knows from the title of the essay, is an "ecological" approach. (shrink)

These are notes designed to bring the beginning student of the philosophy of quantum mechanics 'up to scratch' on the mathematical background needed to understand elementary finite-dimensional quantum theory. There are just three chapters: Ch. 1 'Vector Spaces'; Ch. 2 'Inner Product Spaces'; and Ch. 3 'Operators on Finite-Dimensional Complex Inner Product Spaces'. The notes are entirely self-contained and presuppose knowledge of only high school level algebra.

David Malament (1996) has recently argued that there can be no relativistic quantum theory of (localizable) particles. We consider and rebut several objections that have been made against the soundness of Malament’s argument. We then consider some further objections that might be made against the generality of Malament’s conclusion, and we supply three no‐go theorems to counter these objections. Finally, we dispel potential worries about the counterintuitive nature of these results by showing that relativistic quantum field theory itself explains the (...) appearance of “particle detections.”.

Individuals are faced with the many opportunities to pirate. The decision to pirate or not may be related to an individual''s attitudes toward other ethical issues. A person''s ethical and moral predispositions and the judgments that they use to make decisions may be consistent across various ethical dilemmas and may indicate their likelihood to pirate software. This paper investigates the relationship between religion and a theoretical ethical decision making process that an individual uses when evaluating ethical or unethical situations. An (...) ethical decision making model was studied for general unethical scenarios and for the unethical behavior of software piracy. The research model was tested via path analysis using structural equation modeling and was found to be appropriate for the sample data. The results suggest that there is a relationship between religion and the stages of an ethical decision making process regarding general ethical situations and software piracy. (shrink)

Philosophical reflection on quantum field theory has tended to focus on how it revises our conception of what a particle is. However, there has been relatively little discussion of the threat to the ‘reality’ of particles posed by the possibility of inequivalent quantizations of a classical field theory, i.e. inequivalent representations of the algebra of observables of the field in terms of operators on a Hilbert space. The threat is that each representation embodies its own distinctive conception of what a (...) particle is, and how a ‘particle’ will respond to a suitably operated detector. Our main goal is to clarify the subtle relationship between inequivalent representations of a field theory and their associated particle concepts. We also have a particular interest in the Minkowski versus Rindler quantizations of a free Boson field, because they respectively entail two radically different descriptions of the particle content of the field in the very same region of spacetime. We shall defend the idea that these representations provide complementary descriptions of the same state of the field against the claim that they embody completely incommensurable theories of the field.

Against David Schenck's interpretation, I argue that it is not absolutely clear that Merleau-Ponty ever meant to replace what Schenck refers to as the "unity of meanings" interpretation of "structure" with a "material meanings" interpretation. A particular problem-setting -- for example, an attempt to understand the "truth in naturalism" or the "truth in dualism" -- may very well require a particular mode of expression. I argue that the mode of expression chosen by Merleau-Ponty for these purposes, while unfortunate in some (...) of its apparent implications, need not be interpreted as recommitting him to the doctrine he spent his life working to renounce. I have argued that this would have been clearer had he been able to avail himself of James J. Gibson's notion of affordances, which capture perfectly what he was reaching for. (shrink)

Interest in "embodiment", and over how one may best express the implications of embodiment, is no parochial question, of interest only to a small number of effete philosophers. It confronts perceptual psychologists, developmental psychologists, and psychotherapists, of course. It may not be surprising, either, that it has become an important issue to some students of history and sociology, and to linguists, literary theorists and aestheticians. But that's not all. As physicists -- working within the very bastion of "objective" analysis -- (...) have tried to find expression for what seems to be going on in the domain of sub-atomic nature, they have begun to suggest that physical description itself is inevitably situated. And within the study of artificial intelligence, support is growing for the contention that intelligence cannot be understood entirely formalistically. Intelligence must at least be embodied -- it must somehow display "engaged agency" -- if it is to be recognizable as intelligence. It is within this context that the contribution offered by this essay must be understood. I shall contend that a particular conception -- that of "affordances" -- can, when suitably qualified, offer a conceptual tool of quite exceptional value in the construction of a positive theory of embodied agency, and of its philosophical consequences. (shrink)

While there are numerous differences between the approaches taken by Maurice Merleau-Ponty and James J. Gibson, the basic motivation of the two thinkers, as well as the internal logic of their respective views, is extraordinarily close. Both were guided throughout their lives by an attempt to overcome the dualism of subject and object, and both devoted considerable attention to their "Gestaltist" predecessors. There can be no doubt but that it is largely because of this common cause that the subsequent development (...) of their ideas is so similar. It is not my objective in what follows merely to demonstrate a similarity between two lines of thought. Instead, I will try to show that each approach gains considerably from attention to the other. There are numerous ways to begin such a project, each about as arbitrary as the next. For present purposes, I shall take as of central importance the question of the character of the perceived world, both in relation to the traditionally opposed mental and material "substances", and in relation to its identification and individuation of things vis a vis one another and vis a vis ourselves. This will implicate especially Gibson's "affordances" and Merleau-Ponty's thesis concerning the "materiality of meaning.". (shrink)

VP ellipsis generally requires a syntactically matching antecedent. However, many documented examples exist where the antecedent is not appropriate. Kehler (2000, Linguistics and philosophy 23(6), 533–575. 2002, Coherence, Reference and the Theory of Grammer, CSLI Publications. Stanford.) proposed an elegant theory which predicts a syntactic antecedent for an elided VP is required only for a certain discourse coherence relation (resemblance), not for cause-effect relations. Most of the data Kehler used to motivate his theory come from corpus studies and thus (...) do not consist of true minimal pairs. We report five experiments testing predictions of the coherence theory, using standard minimal pair materials. The results raise questions about the empirical basis for coherence theory because a syntactically-matching antecedent is preferred for all coherence relations, not just resemblance relations. Further, strict identity readings, which should not be available when a syntactic antecedent is required, are influenced by parallelism per se, holding the discourse coherence relation constant. This draws into question the causal role of coherence relations in processing VP ellipsis. (shrink)

While there is no shortage of scholarship on the topic, there appears to be no widely accepted definition of critical thinking. This is coupled with the troublesome fact that those in higher education often believe their definitions are the norm. In this article, we demonstrate a lack of uniformity through a representative sample of historically influential definitions for critical thinking. These definitions are then classified into two distinct categories: context specific and cross-disciplinary definitions. From this lack of uniformity we argue (...) that at least two problems in higher education arise: lack of proper critical thinking assessment and difficulty in interdisciplinary collaboration on the topic of critical thinking. Given the current focus on critical thinking assessment alongside a movement toward greater interdisciplinary collaboration within higher education, we conclude with a call for a uniform definition of critical thinking.

Numerous searches have failed to identify a single co-occurrence of total blindness and schizophrenia. Evidence that blindness causes loss of certain NMDA-receptor functions is balanced by reports of compensatory gains. Connections between visual and anterior cingulate NMDA-receptor systems may help to explain how blindness could protect against schizophrenia.

Sensation should be understood globally: some infant behaviors do not make sense on the model of separate senses; neonates of all species lack time to learn about the world by triangulating among different senses. Considerations of natural selection favor a global understanding; and the global interpretation is not as opposed to traditional work on sensation as might seem.

We show that three fundamental information-theoretic constraints -- the impossibility of superluminal information transfer between two physical systems by performing measurements on one of them, the impossibility of broadcasting the information contained in an unknown physical state, and the impossibility of unconditionally secure bit commitment -- suffice to entail that the observables and state space of a physical theory are quantum-mechanical. We demonstrate the converse derivation in part, and consider the implications of alternative answers to a remaining open question about (...) nonlocality and bit commitment. (shrink)

My main objective, in this paper, is to present at least a rough sketch of a new model for understanding time. Since many people are quite content with the model that they have, it will be worth while to show why a new model might be desirable, or even necessary. As it happens, looking at the problems involved in the more usual conception of time leads one naturally to look in certain directions for solutions, and such an introduction can therefore (...) explain why the new model looks the way it does. With all this in mind, then, this paper will be broken down into three parts. In the first part, I’ll try to show that no-one has ever experienced time as such. In the second part, I shall argue that one good reason for this is that there is no such thing as time proper. Finally, in the third part, I’ll try to reassemble what’s left of the conception of time after all this demolition, and I’ll offer a positive model (albeit rather vague) of what I prefer to call "temporality".

What characterizes most technical or theoretical accounts of memory is their reliance upon an internal storage model. Psychologists and neurophysiologists have suggested neural traces (either dynamic or static) as the mechanism for this storage, and designers of artificial intelligence have relied upon the same general model, instantiated magnetically or electronically instead of neurally, to do the same job. Both psychology and artificial intelligence design have heretofore relied, without much question, upon the idea that memory is to be understood as a (...) matter of internal storage. In what follows, I shall first sketch the most important reasons for skepticism about this model, and I shall then propose an outline of an alternative way of talking about memory.

Benjamin Franklin's social and political thought was shaped by contacts with and knowledge of ancient aboriginal traditions. Indeed, a strong case can be made that key features of the social structure eventually outlined in the United States Constitution arose not from European sources, and not full-grown from the foreheads of European-American "founding fathers", but from aboriginal sources, communicated to the authors of the Constitution to a significant extent through Franklin. A brief sketch of the main argument to this effect is (...) offered in this essay. (shrink)

Progress in the last few decades in what is widely known as “Chaos Theory” has plainly advanced understanding in the several sciences it has been applied to. But the manner in which such progress has been achieved raises important questions about scientific method and, indeed, about the very objectives and character of science. In this presentation, I hope to engage my audience in a discussion of several of these important new topics.

There is a great deal that might be said about justice in property claims. The strategy that I shall employ focuses attention upon the initial acquisition of property -- the most sensitive and most interesting area of property theory. Every theory that discusses property claims favorably assumes that there is some justification for transforming previously unowned resources into property. It is often this assumption which has seemed, to one extent or another, to be vulnerable to attack by critics of particular (...) justifications of property. Nevertheless, this assumption is frequently left undefended by property theorists, and where it is defended, the defense is often remarkably weak. That some initial claim to property be defensible is required by any theory which holds that certain present distributions may be justified, that certain transfers of property are justified, or that restitution ought to be made for previous injustice in transfer or acquisition. The initial acquisition of property, and its justification, is crucial to the remainder of property theory. (shrink)

Freedom is generated in at least two distinct ways: as the ability to avoid perceived dangers and pursue perceived goods, and even to pursue complicated plans in those directions, freedom evolves. But as a social and political matter, freedom seems more subject to human will. The best social institutions -- the kind that serve to encourage or constrain freedom of choice -- also appear to be evolutionary products in some sense. Can there be too much freedom? Of course there can. (...) No constraint at all would guarantee personal and social disaster. Individual activity can pose serious dangers to nature and to culture. But how may we ensure that the constraints we may chose to impose our ones that are good for us? What we need to do is to find, as consistently as possible with the necessity that human individuals be able to use their local perception of local opportunity in pursuit of their own interests, a framework that emerges out of human practice; we should take advantage of lessons learned about evolution: those strategies work that are in tune with the forces at work within the niche. In our attempts to solve social problems, we can't afford to take our eyes off the characteristics of the individuals that make up the social world we hope to change. And in my view, here as elsewhere, the smallest intervention is likely to be the best. (shrink)

For John Morreall, cuteness is an abstract general attribute of infants that causes adults to want to care for them (or which is the reason, or at least important reason, for such solicitousness). I shall try to show, in what follows, that this is, if not an altogether fallacious way of explaining the matter, at least an extremely misleading one. As it stands, in particular, it is too easy to infer from Morreall's line of reasoning 1) that infants in general (...) might conceivably never have developed cuteness, and 2) that infants, because of this deficiency, would then not be cared for as adequately by their parents. An equally wrong further implication, which further helps to express my difficulty with Morreall's formulation of the matter, would be that if baby spiders (for example) had happened to have the abstract general characteristic called 'cuteness', while human children did not have it, then human adults would have been more inclined to care for baby spiders than for baby humans. It is to avoid such oddities as these that, it seems to me, a further consideration of the problem is warranted. (shrink)

We prove a uniqueness theorem showing that, subject to certain natural constraints, all 'no collapse' interpretations of quantum mechanics can be uniquely characterized and reduced to the choice of a particular preferred observable as determine (definite, sharp). We show how certain versions of the modal interpretation, Bohm's 'causal' interpretation, Bohr's complementarity interpretation, and the orthodox (Dirac-von Neumann) interpretation without the projection postulate can be recovered from the theorem. Bohr's complementarity and Einstein's realism appear as two quite different proposals for selecting (...) the preferred determinate observable--either settled pragmatically by what we choose to observe, or fixed once and for all, as the Einsteinian realist would require, in which case the preferred observable is a 'beable' in Bell's sense, as in Bohm's interpretation (where the preferred observable is position in configuration space). (shrink)

Although Bohr's reply to the EPR argument is supposed to be a watershed moment in the development of his philosophy of quantum theory, it is difficult to find a clear statement of the reply's philosophical point. Moreover, some have claimed that the point is simply that Bohr is a radical positivist. In this paper, we show that such claims are unfounded. In particular, we give a mathematically rigorous reconstruction of Bohr's reply to the _original_ EPR argument that clarifies its logical (...) structure, and which shows that it does not rest on questionable philosophical assumptions. Rather, Bohr's reply is dictated by his commitment to provide "classical" and "objective" descriptions of experimental phenomena. (shrink)

I try in this essay to accomplish two things. First I offer some first thoughts toward a clarification of the ethical foundations of private property rights that avoids pitfalls common to more strictly Lockean theories, and is thus better prepared to address arguments posed by critics of standard private property arrangements. Second, I'll address one critical argument that has become pretty common over the years. While versions of the argument can be traced back at least to Pierre Joseph Proudhon, I'll (...) focus on a formulation given it by Jeremy Waldron. The basic idea is that the only sound arguments for private property rights lead to the conclusion that society has an obligation to insure that every citizen possess private property. In Waldron's formulation, what is justifiable is a general, rather than a special, right to private property. I shall try to suggest that this conclusion is unwarranted. (shrink)

In a pair of articles (1996, 1997) and in his recent book (1998), Miklos Redei has taken enormous strides toward characterizing the conditions under which relativistic quantum field theory is a safe setting for the deployment of causal talk. Here, we challenge the adequacy of the accounts of causal dependence and screening off on which rests the relevance of Redei's theorems to the question of causal good behavior in the theory.

In this paper (which is, at best, a work in progress), I discuss different modes of scientific explanation identified by philosophers (Hempel, Salmon, Kitcher, Friedman, Hughes) and examine how well or badly they capture the "explanations" of phenomena that modern quantum theory provides. I tentatively conclude that quantum explanation is best seen as "structural explanation", and spell out in detail how this works in the case of explaining vacuum correlations. Problems and prospects for structural explanation in quantum theory are also (...) discussed. (shrink)

Orthodox quantum mechanics includes the principle that an observable of a system possesses a well-defined value if and only if the presence of that value in the system is certain to be confirmed on measurement. Modal interpretations reject the controversial ‘only if’ half of this principle to secure definite outcomes for quantum measurements that leave the apparatus entangled with the object it has measured. However, using a result that turns on the construction of a Kochen–Specker contradiction, I argue that modal (...) interpretations cannot deliver a metaphysically tenable conception of properties in quantum mechanics unless they also abandon the less controversial ‘if’ half of the orthodox principle.

The most important voices concerning the changes now occurring in Central and Eastem Europe are those that come from within, for those voices are informed not only by indifferent data and objective reports, but by personal hopes, fears, desires and needs. Without careful consideration of what such voices say, judgment can only be sterile. Furthermore, policy decisions made without the benefit of the intemal perspective are likely to be flawed, and ineffectual. Policies won’t work if they do not take into (...) account the point of view of those who are supposed to be affected by them. There nevertheless remains an important role for outsiders to play in the discussion of the impact of political change on the future of philosophical thought, especially if the outside perspective can serve as a test of the internal view.

In The Libertarian Idea, Jan Narveson explains his interpretation of social contract theory this way: "The general idea of this theory is that the principles of morality are (or should be) those principles for directing everyone's conduct which it is reasonable for everyone to accept. They are the rules that everyone has good reason for wanting everyone to act on, and thus to internalize in himself or herself, and thus to reinforce in the case of everyone." It is plain, here, (...) that Narveson believes that social contract is to provide justification -- a foundation, in fact -- for 'the principles of morality'. The burden assumed in this essay is to examine how far Narveson has succeeded in making this foundational claim plausible. (shrink)

In the midst of even the most tragic circumstances attending the aftermath of disaster, and co-existing with a host of complex emotions, arises a practical consideration: how might similar tragedies be prevented in the future? The complexity of such situations must not be neglected. More than mere prevention must usually be taken into consideration. But the practical question is of considerable importance. In what follows, I will offer some reasons for being concerned that efforts to fix the problem -- efforts, (...) that is, directed toward insuring that similar tragedies do not occur in the future -- can easily be obstructed by attempts to fix blame -- that is, efforts directed toward determining which agent among those involved is guilty of wrong-doing. This is the case, I shall contend, even where some agent or another really is guilty of wrong-doing. The problem is further complicated by a pervasive human tendency to imagine that some agent or another must be responsible in some way for any tragedy that occurs -- even when this is not really true -- but its influence is not at all limited to such cases. As I shall suggest, philosophical attitudes toward issues of determinism and free will may be implicated in the different approaches people take to the problem of assessing what has gone wrong in a particular case and how to fix it, but such deep philosophical problems need not be resolved here. The point is not that humans are never guilty of wrong-doing (since their actions, the argument might go, are all products of outside forces), but rather that whatever the case may be about guilt, tracking down guilty persons is a different business from fixing institutionally-embedded problems so as to lessen the likelihood of their recurrence.

Risk is not always nasty. Risk can be the cost of opportunity, of course; but sometimes risk is regarded not as a cost at all, but as a close attendant of pleasure. Many things that people invest considerable time and resources in would not be pursued at all if not for the attendant risk. Attempting to offer clarification of the role that risk plays in human affairs is thus itself a risky business. People largely want to avoid unnecessary risk except (...) when they deliberately seek it out. One might be tempted to say that people are funny that way. In what follows, I shall attempt to undermine the temptation to say this. I shall argue that there is nothing at all odd or funny about the fact that people are sometimes drawn to and sometimes repelled by risk. I would contend, further, that a clear understanding of the way value enters human affairs not only allows but requires this. (shrink)

In their article "On What It Takes To Be a World", David Albert and Jeffrey Barrett raise "a rather urgent question about what the proponents of a many-worlds interpretation [of quantum mechanics] can possibly mean by the term 'worlds' " (1995, 35). I argue that their considerations do not translate into an argument against the Many-Worlds conception of a world unless one requires that the dispositions that measurement devices display through the outcomes they record be explainable in terms of facts (...) particular to the worlds in which those devices do their recording. Granting that their conception of a world takes away the possibility of such an explanation, a Many-Worlds proponent can claim that the Universal quantum state, which does not represent a fact about any world in particular, is enough to ground the dispositions of measurement devices.

The paper provides a critical review of thedebate on the foundations of Computer Ethics(CE). Starting from a discussion of Moor'sclassic interpretation of the need for CEcaused by a policy and conceptual vacuum, fivepositions in the literature are identified anddiscussed: the ``no resolution approach'',according to which CE can have no foundation;the professional approach, according to whichCE is solely a professional ethics; the radicalapproach, according to which CE deals withabsolutely unique issues, in need of a uniqueapproach; the conservative approach, accordingto which CE (...) is only a particular appliedethics, discussing new species of traditionalmoral issues; and the innovative approach,according to which theoretical CE can expandthe metaethical discourse with a substantiallynew perspective. In the course of the analysis,it is argued that, although CE issues are notuncontroversially unique, they are sufficientlynovel to render inadequate the adoption ofstandard macroethics, such as Utilitarianismand Deontologism, as the foundation of CE andhence to prompt the search for a robust ethicaltheory. Information Ethics (IE) is proposed forthat theory, as the satisfactory foundation forCE. IE is characterised as a biologicallyunbiased extension of environmental ethics,based on the concepts of information object/infosphere/entropy rather thanlife/ecosystem/pain. In light of the discussionprovided in this paper, it is suggested that CEis worthy of independent study because itrequires its own application-specific knowledgeand is capable of supporting a methodologicalfoundation, IE.

In this paper, I try to explain the philosophical problems that Niels Bohr felt had been exposed by the discovery of the "quantum of action," and by the emergence of the quantum theory that arose in large part as a result of his efforts. I won't have space to make the case adequately here, but my own view is that we have not yet fully digested the message brought to us by Bohr's "Copenhagen Interpretation" of Quantum Mechanics, and I suspect (...) that it will finally prove to be every bit as revolutionary as Bohr thought it was.

Moral reasoning traditionally distinguishes two types of evil:moral (ME) and natural (NE). The standard view is that ME is theproduct of human agency and so includes phenomena such as war,torture and psychological cruelty; that NE is the product ofnonhuman agency, and so includes natural disasters such asearthquakes, floods, disease and famine; and finally, that morecomplex cases are appropriately analysed as a combination of MEand NE. Recently, as a result of developments in autonomousagents in cyberspace, a new class of interesting and (...) importantexamples of hybrid evil has come to light. In this paper, it iscalled artificial evil (AE) and a case is made for considering itto complement ME and NE to produce a more adequate taxonomy. Byisolating the features that have led to the appearance of AE,cyberspace is characterised as a self-contained environment thatforms the essential component in any foundation of the emergingfield of Computer Ethics (CE). It is argued that this goes someway towards providing a methodological explanation of whycyberspace is central to so many of CE's concerns; and it isshown how notions of good and evil can be formulated incyberspace. Of considerable interest is how the propensity for anagent's action to be morally good or evil can be determined evenin the absence of biologically sentient participants and thusallows artificial agents not only to perpetrate evil (and forthat matter good) but conversely to `receive' or `suffer from'it. The thesis defended is that the notion of entropy structure,which encapsulates human value judgement concerning cyberspace ina formal mathematical definition, is sufficient to achieve thispurpose and, moreover, that the concept of AE can be determinedformally, by mathematical methods. A consequence of this approachis that the debate on whether CE should be considered unique, andhence developed as a Macroethics, may be viewed, constructively,in an alternative manner. The case is made that whilst CE issuesare not uncontroversially unique, they are sufficiently novel torender inadequate the approach of standard Macroethics such asUtilitarianism and Deontologism and hence to prompt the searchfor a robust ethical theory that can deal with them successfully.The name Information Ethics (IE) is proposed for that theory. Itis argued that the uniqueness of IE is justified by its beingnon-biologically biased and patient-oriented: IE is anEnvironmental Macroethics based on the concept of data entityrather than life. It follows that the novelty of CE issues suchas AE can be appreciated properly because IE provides a newperspective (though not vice versa). In light of the discussionprovided in this paper, it is concluded that Computer Ethics isworthy of independent study because it requires its ownapplication-specific knowledge and is capable of supporting amethodological foundation, Information Ethics.

Both professors and institutions of higher education benefit from a vision of academic life that is grounded more firmly in myth than in history. According to the myth created by that traditional vision, scholars pursue research wherever their drive to knowledge takes them, and colleges and universities transmit the fruits of that research to contemporary and future generations as the accumulated wisdom of the ages. Yet the economic and social forces operating on colleges and universities as institutions, as well as (...) on the interests of faculty members within them, are making the myth embodied in the traditional ideal of the academy more and more difficult to sustain. Questions about what an institution of higher education ought to be, about what professors ought to do, and about what relations professors ought to have to the institutions which employ them are being raised and pushed to the fore. These are not theoretical questions, but practical questions of immediate import that must be answered relatively quickly -- and wisely -- if institutions of higher education and professors are not to find themselves inextricably in the grip of forces they cannot change. The myth of disinterested academic research-however beautiful -- and however beneficial -- is under siege. (shrink)

I begin this essay with a notion of "authority" that makes a sharp distinction between authority and power, and grant that such authority is not only legitimate, but perhaps even necessary in human affairs. I then trace the devaluation of this idea through varying degrees of institutionalization, culminating in its political cooptation. I argue, finally, that what goes by the name of political authority is the very antithesis of the legitimate and necessary element that we began with.

Which risks are bad? This is not an easy question to answer in any non-circular way. Not only are risks sought out for various reasons, but risks are plainly discounted in many situations. What may seem "risky" when examined all by itself, may not seem risky when encountered in a real lived situation. Thus risks that are imposed by others, in particular, might seem horrendous when considered in abstraction, but quite acceptable when encountered in life. What we need to do, (...) among other things, is to examine this "seeming." Are people being deluded or distracted when they fail to take seriously the riskiness of activities undertaken by others, or does this make some rational sense? There can be no doubt that people sometimes are deluded, of course. We are all fallible. But risks are not unalloyed evils. They are typically taken because of their association with something positive. So questions about whether people are making wise judgments when they don’t care about certain risks that they take, or, on the other side of the coin, when they become absolutely hysterical when confronted with a risk that appears to others to be insignificant, hinge on a web of further factors.

The Einstein-Podolsky-Rosen argument for the incompleteness of quantum mechanics involves two assumptions: one about locality and the other about when it is legitimate to infer the existence of an element-of-reality. Using one simple thought experiment, we argue that quantum predictions and the relativity of simultaneity require that both these assumptions fail, whether or not quantum mechanics is complete.

People have been arguing about natural law for at least a couple of thousand years now. During that time, a number of substantially different sorts of theory have been identified as falling within the natural law tradition. Even within each sort of natural law theory, there has been a variety of quite different arguments proposed, both in behalf of and in opposition to the theory. These facts about the natural law tradition serve to confound its critics. It's extremely tough to (...) get a tidy formulation of just what natural law theory is, and such a formulation is needed if the theory is to be analyzed as to its adequacy, truth, value, or whatever. I am going to try to perform such an analysis nonetheless, and to do it as neatly as possible within a fairly short space. (shrink)

This paper examines the question of whether the theory of simply foreknowledge (SF) provides God with greater providential control than does the theory of present knowledge (PK).

To see whether this is the case I first distinguish two different versions of how God’s foreknowledge is accessed according (...) to simple foreknowledge. These two versions are then utilized to examine seven different areas of divine providence to assess the utility of simple foreknowledge.

While I strongly agree with Patrick Grim that abstract relationships are real, and that it is possible to get them right, the danger that we will get them wrong is just as real. The use of visual representation of abstract phenomena, precisely because of our predilection to see patterns in everything and because we don't have to think so hard about visible representations generally, may lead us to see things that aren't there.

An understanding of the ethical problems that have arisen in the funding of scientific research at universities requires some attention to doctrines that have traditionally been held about science itself. Such doctrines, we hope to show, are themselves central to many of these ethical problems. It is often thought that the questions examined by scientists, and the theories that guide scientific research, are chosen for uniquely scientific reasons, independently of extra-scientific questions of value or merit. We shall argue that this (...) is an illusion. It is an illusion to think, especially in the present era, that science can even have a coherent direction apart from extra-scientific considerations.

The distinguishing feature of ‘modal’ interpretations of quantum mechanics is their abandonment of the orthodox eigenstate–eigenvalue rule, which says that an observable possesses a definite value if and only if the system is in an eigenstate of that observable. Kochen's and Dieks' new biorthogonal decomposition rule for picking out which observables have definite values is designed specifically to overcome the chief problem generated by orthodoxy's rule, the measurement problem, while avoiding the no-hidden-variable theorems. Otherwise, their new rule seems completely ad (...) hoc. The ad hoc charge can only be laid to rest if there is some way to give Kochen's and Dieks' rule for picking out which observables have definite values some independent motivation. And there is, or so I will argue here. Specifically, I shall show that theirs is the only rule able to save Schrödinger's cat from a fate worse than death, and sidestep the Bell–Kochen–Specker no-hidden-variables theorem, once we impose four independently natural conditions on such rules.

In response to Professor Rorty’s reaction to Professor Habermas’s paper in this symposium, I confess that I am still not sure I understand Rorty’s hostility to ideals such as the ideal of truth. Such ideals as the ideal of truth -- and ideals like those of reason and morality surely stand and fall with the ideal of truth -- seem plainly to have an enormous pragmatic value. They lure us out of our too-constrained, too-limited ethnocentric or idiosyncratic frames of reference. (...) It is always possible, of course, that such ideals may be abused; they have frequently been deployed, in particular, as clubs used to beat down views and modes of behavior that are threatening or otherwise disliked. But they need not be abused. Their proven and potential value is quite extraordinary. They offer us standards which pay explicit respect to the principle that the criteria we use for evaluating ideas and modes of behavior should be nonethnocentric and nonidiosyncratic. They offer us standards that we can appeal to in luring ourselves or others to step outside of our relatively narrow present points of view here and now and toward a broader perspective that can serve us better tomorrow and elsewhere.

Peter Lewis ([1997]) has recently argued that the wavefunction collapse theory of GRW (Ghirardi, Rimini and Weber [1986]) can only solve the problem of wavefunction tails at the expense of predicting that arithmetic does not apply to ordinary macroscopic objects. More specifically, Lewis argues that the GRW theory must violate the enumeration principle: that 'if marble 1 is in the box and marble 2 is in the box and so on through marble n, then all n marbles are in the (...) box' ([1997], p. 321). Ghirardi and Bassi ([1999]) have replied that it is meaningless to say that the enumeration principle is violated because the wavefunction Lewis uses to exhibit the violation cannot persist, according to the GRW theory, for more than a split second ([1999], p. 709). On the contrary, we argue that Lewis's argument survives Ghirardi and Bassi' s criticism unscathed. We then go on to show that, while the enumeration principle can fail in the GRW theory, the theory itself guarantees that the principle can never be empirically falsified, leaving the applicability of arithmetical reasoning to both micro- and macroscopic objects intact.

Pragmatists, as I understand them, have their own view of what truth and progress are. William James, quite famously, offered a straightforward pragmatic definition of truth.

This paper proposes a notion, the ?ambit? of an action, that allows the degree of distribution of an action in a multiagent system to be quantified without regard to its functionality. It demonstrates the use of that notion in the design, analysis and implementation of dynamically-reconfigurable multi-agent systems. It distinguishes between the extensional (or system) view and intensional (or agent-based) view of such a system and shows how, using the notion of ambit, the step-wise derivation paradigm of Formal Methods can (...) be used to derive the latter from the former. In closing it addresses the manner in which these ideas inform studies in the ethics of systems of artificial agents. (shrink)

In support of a recent conjecture by Nielsen (1999), we prove that the phenomena of ‘incomparable entanglement’— whereby, neither member of a pair of pure entangled states can be transformed into the other via local operations and classical communication (LOCC)—is a generic feature when the states at issue live in an infinite-dimensional Hilbert space.  2002 Elsevier Science B.V.

Democratically inspired critics identify a number of problems with the contemporaryidentification of survey research and public opinion. Surveys are said tonormalize or rationalize opinion, to promote state or corporate rather thandemocratic interests, to constrain authentic forms of participation, and to forcean individualized conception of public opinion. Some of these criticisms arerelatively easily answered by survey researchers. But the criticisms contain acomplaint that survey researchers have largely failed to address: that surveyresearch discourages the public, visible, and face-to-face generation of opinion.Public opinion (...) researchers who use surveys paradoxically seek the opinions ofcitizens in private, nonpolitical situations. But nothing inherent in the methodsof survey research requires this private focus. The author argues that by reframingthe survey's unit of analysis and considering alternatives to standard,national samples in political surveys, new democratic possibilities within surveyresearch may be found.

As complicated an affair as it may be to give a fully acceptable general characterization of professional codes of ethics that will capture every nuance, one theme that has attracted widespread attention portrays them as contrivances whose primary function is to secure certain obligations of professionals to clients, or to the external community. In contrast to such an "externalist" characterization of professional codes, it has occasionally been contended that, first and foremost, they should be understood as internal conventions, adopted among (...) professionals as a device for securing the "interests" of the professionals themselves. In what follows, I will argue that both of these lines are incomplete. As important as service to the community and the interests of professionals may be in the full understanding of the multiple role that "codes of ethics" play in many professions, it is equally important to see them as expressive of the romance of a profession. Professional codes should be understood not only in terms of their utility to the community, or in terms of their utility to practitioners, but as expressions of callings. Analyses of professional codes of ethics that do not take into consideration their role in evoking the romance of a professional calling are thus not entirely adequate. Professional standards and codes can be fully understood only if one appreciates that they are designed to contribute to and evoke feelings of dignity, self-worth-and, for better or for worse, even the superiority--of the professionals themselves; the code may seem to them to express essential features of what the profession really is.

Analyzing three key cases that arose in 1993, I argue that the practice of sending in "testers" -- persons posing as job applicants -- to ferret out workplace discrimination is easier to defend from an ethical standpoint in an agency's investigation stems from an actual complaint. By contrast, defendants may rightfully challenge the legitimacy of the procedures used for "test" subjects when an investigation is based solely on the general goals of an antidiscrimination agency.

I examine the claim that the underlying importance given to freedom within a society's scheme of values varies with historical circumstance and social context (I shall sometimes call this the "relativist claim"). The point of the examination will be to attempt to determine the manner in which, and the extent to which, this claim really endangers the liberal argument, which seems to suggest that freedom is valuable everywhere and always. It will be seen that several apparent challenges may be dismissed, (...) since for one reason or another they do not really threaten traditional liberalism. When these apparent (but non-threatening) challenges are pared away from the relativist claim, it will be seen that the remaining threat is on the one hand weaker, and on the other hand more dubious, than might have been supposed at first. This rather formal work will then set the stage for a proffered definition of the sort of "freedom" that is at stake in this discussion, and for my own attempt to offer answers to the questions about the value of freedom that I raise.

By exhibiting a violation of a novel form of the Bell-CHSH inequality, \.{Z}ukowski has recently established that the quantum correlations exploited in the standard perfect teleportation protocol cannot be recovered by any local hidden variables model. Allowing the quantum channel state in the protocol to be given by any density operator of two spin-1/2 particles, we show that a violation of a generalized form of \.{Z}ukowski's teleportation inequality can only occur if the channel state, considered by itself, violates a Bell-CHSH (...) inequality. On the other hand, although it is sufficient for a teleportation process to have a nonclassical fidelity---defined as a fidelity exceeding $2/3$---that the channel state employed violate a Bell-CHSH inequality, we show that such a violation does \emph{not} imply a violation of \.{Z}ukowski's teleportation inequality or any of its generalizations. The implication does hold, however, if the fidelity of the teleportation exceeds $2/3(1+1/2\sqrt{2})\approx .90$, suggesting the existence of a regime of nonclassical values of the fidelity, less than $.90$, for which the standard teleportation protocol can be modelled by local hidden variables.

The most recent attempt at factually establishing a "true" value for the one-way velocity of light is shown to be faulty. The proposal consists of two round-trip photons travelling first in vacuo and then through a medium of refractive index n before returning to their common point of origin. It is shown that this proposal, as well as a similar one considered by Salmon (1977), presupposes that the one-way velocities of light are equal to the round-trip value. Furthermore, experiments of (...) this type, involving regions of space with varying refractive indices, cannot "single out" any factual value for the Reichenbach-Grünbaum ε factor thus posing no threat to the conventionalist thesis.
