In a recent article Humphreys has developed an intriguing proposal for making sense of emergence. The crucial notion for this purpose is what he calls "fusion" and his paradigm for it is quantum nonseparability. In what follows, we will develop this position in more detail, and then discuss its ramifications and limitations. Its ramifications are quite radical; its limitations are substantial. An alternative approach to emergence that involves quantum physics is then proposed.

This paper involves one crucial assumption; namely, that the statistical predictions of quantum mechanics for Bell's variant of the EPR experiment will continue to be verified as detector efficiencies are improved and the need for coincidence counters is eliminated. This assumption entails that any hidden-variables theory for quantum mechanics must violate Bell's inequality--the inequality derived in Bell (1964). It is shown here that four locality conditions are involved in the derivation of Bell's inequality; and that a violation of any of (...) the four locality conditions will either entail the existence of superluminal influences or the existence of superluminal signals (superluminal influences that can be used to transmit information), if conspiratorial theories can be ruled out. The attempts so far to rule out conspiratorial theories are all found to be rather dubious, but there are other considerations developed here that rule them out convincingly. Finally, it is demonstrated that violations of each of the four locality conditions can be used to transmit information superluminally, if certain auxiliary conditions are satisfied. This is of particular interest because one of these conditions corresponds to a condition dubbed "completeness" by Jon Jarrett. Jarrett and others have suggested that violations of completeness cannot be used to send information superluminally. Demonstrating otherwise is, perhaps, the most significant result obtained in this paper. (shrink)

An examination of determinism in the context of chaotic dynamics.

Conventional wisdom has it that chaotic behavior is either strongly suppressed or absent in quantum models. Indeed, some researchers have concluded that these considerations serve to undermine the correspondence principle, thereby raising serious doubts about the adequacy of quantum mechanics. Thus, the quantum chaos question is a prime subject for philosophical analysis. The most significant reasons given for the absence or suppression of chaotic behavior in quantum models are the linearity of Schrödinger’s equation and the unitarity of the time-evolution described (...) by that equation. Both are shown in this essay to be irrelevant by demonstrating that the crucial feature for chaos is the nonseparability of the Hamiltonian. That demonstration indicates that quantum chaos is likely to be exhibited in models of open quantum systems. A measure for probing such models for chaotic behavior is developed, and then used to show that quantum mechanics has chaotic models for systems having a continuous energy spectrum. The prospects of this result for vindicating the correspondence principle (or the motivation behind it, at least) are then briefly examined. (shrink)

Two notions of evidence are focused on in this essay, Carnap's positive-relevance notion of evidence (1962, pp. 462 ff.), and Achinstein's notion of potential evidence (1978; and 1983, pp. 322–350). Achinstein creates several interesting examples in his attempt to find faults in Carnap's notion of evidence; his motive, ultimately, is to impel us towards potential evidence. The purpose of this essay is to show that positive relevance is significantly more promising than potential evidence with respect to capturing the scientific sense (...) of the term evidence. This is accomplished by finding faults in the notion of potential evidence, and by defending positive relevance against Achinstein's examples. (shrink)

This paper is a critical discussion of a recent article by Bas van Fraassen in which he suggests the following view: we should admit that we have no explanation of the EPR correlations, but refuse to consider the correlations as mysterious nevertheless. We shall focus on just three of the claims made by van Fraassen in support of this view. The three claims are these:The EPR correlations cannot be explained by signals being transmitted from one component of an EPR compound (...) to the other.There is, in the EPR situation, no empirically verifiable action at a distance.The demand for an explanation of the EPR correlations is similar to the Aristotelian demand of the post-Newtonian proponents of the law of inertia to explain what keeps a body moving if there are no forces impressed on it.

I defend the projection postulate against two of Margenau's criticisms. One involves two types of nonideal measurements, measurements that disturb and measurements that annihilate. Such measurements cannot be characterized using the original version of the projection postulate. This is one of the most interesting and powerful objections to the projection postulate since most realistic measurements are nonideal, in Margenau's sense. I show that a straightforward generalization of the projection postulate is capable of handling the more realistic kinds of measurements considered (...) by Margenau. His other objection involves the EPR (Einstein-Podolsky-Rosen) situation. He suggests that there is a significant potential for violations of the no-superluminalsignals requirement of the special theory of relativity, if projections occur in this situation and others like it. He also suggests that what is paradoxical about this situation disappears if the projection postulate is rejected. I show that it is not possible to use measurements on pairs of spatially-separated systems whose states are entangled to transmit information superluminally, and generalize this result to include nonideal measurements. I also show that EPR's dilemma does not really depend on the projection postulate. (shrink)

The purpose of this paper is to solve a serious problem for the projection postulate involving the time-energy uncertainty relation. The problem was recently raised by Teller, who believes that the problem is insoluble and, consequently, that the projection postulate should no longer be regarded as a serious focus for interpretive investigation.

The standard mathematical formulation of quantum mechanics is specified. Bohm's ontological interpretation of quantum mechanics is then shown to be incapable of providing a suitable interpretation of that formulation. It is also shown that Bohm's interpretation may well be viable for two alternative mathematical formulations of quantum mechanics, meaning that the negative result is a significant though not a devastating criticism of Bohm's interpretation. A preliminary case is made for preferring one alternative formulation over the other.

In a previous essay I argued that quantum chaos cannot be exhibited in models of quantum systems within von Neumann's mathematical framework for quantum mechanics, and that it can be exhibited in models within Dirac's formal framework. In this essay, the negative thesis concerning von Neumann's framework is elaborated further by extending it to the case of Hamiltonian operators having a continuous spectrum. The positive thesis concerning Dirac's formal framework is also elaborated further by constructing a chaotic model of an (...) open quantum system in which an entropy measure is shown to approach its maximum value as time goes to infinity. Having such an entropy measure is a characteristic that is closely connected to chaotic behavior in phase space models of classical systems. (shrink)

Jarrett has demonstrated that "strong locality," one of the conditions used by Bell to derive his well known inequality, is equivalent to the conjunction of two other conditions which he calls "hidden locality" and "completeness." He has also demonstrated that if it is possible to control the hidden states of the measured system, then violations of hidden locality can be used to transmit information superluminally; and that this is not so with respect to violations of completeness. This he has taken (...) to mean that it is not possible to use violations of completeness to do so under any circumstances. In this essay, it is argued that such violations can be used to do so, if one other condition is satisfied. (shrink)

Bell (1964) demonstrated that if two restrictions are imposed on the hypothetical hidden variables supposed to underlie quantum mechanical states, then it is possible to derive an inequality that is violated by certain predictions of QM (Quantum Mechanics); the predictions concern pairs of systems whose states are strongly correlated. The two restrictions are denoted herein as SL (Strong Locality) and HA (Hidden Autonomy)1, and the inequality as BI (the Bell Inequality). Since SL and HA together entail BI, and QM violates (...) BI, it follows that any HVT (Hidden-Variables Theory) for QM must violate either SL or HA.It is well known that a condition known as PA (Perfect Anti-correlation) was also used by Bell to derive the inequality. PA says that parallel experiments (experiments with parallel spin-analyzer orientations) never yield the same results. (shrink)

The four essays in this volume examine the most central issues that face liberal democratic regimes. They tackle the protection of individual liberty, the basic principles of ethics, the benefits and the costs of representative institutions, and the central importance of gender equality in society.

This is a sophisticated, nontechnical introduction to the main issues in the philosophy of physics. It is exceptionally well-written. The issues are well-chosen, the prose are clear and concise, the text is organized into manageable sections arranged in a logical manner, and the treatment of various positions on the main issues is evenhanded. Also, each of the three central chapters is supplemented by an annotated bibliography that will serve well as a selective guide for motivated readers.

Can a corporation have a conscience? What is wrong with reverse discrimination? Can ethical management and managed care coexist? Hoffman, Frederick, and Schwartz address these and many other current, intriguing, often complex issues in corporate morality. This introductory business ethics text contains a thorough general introduction on ethical theory, 54 readings, and 25 cases. Divided into five parts, each with an introduction that presents the major themes of its articles and cases, the text contains an impartial, point-counterpoint presentation of (...) different perspectives on the most important issues being debated in business ethics. Each chapter ends with questions that can be used for student discussion, review, tests/quizzes, or for student assignments. The fourth edition has 27 new readings, 15 new cases, and 10 new mini-cases. (shrink)

Contemporary liberal theorists generally support open borders and some argue that liberalism is incompatible with substantive immigration control. We argue that it has not been shown that there is an inconsistency in the idea of a liberal state enforcing such controls and that it may be obligatory for a liberal state to impose substantive restrictions on immigration. The immigration control on which we focus is that concerning people from societies that resemble closed societies, particularly those in which Islamic fundamentalism is (...) endemic. We suggest that, if the threat we envision is real, then a liberal state has a right to limit immigration from such societies. (shrink)

Recently, Rueger and Sharp (1996) and Koperski (1998) have been concerned to show that certain procedural accounts of model confirmation are compromised by non-linear dynamics. We suggest that the issues raised are better approached by considering whether chaotic data analysis methods allow for reliable inference from data. We provide a framework and an example of this approach.

This book is the first comprehensive study of Rousseau's rich and complex theory of the type of self-love (amour proper) that, for him, marks the central difference between humans and the beasts. Amour proper is the passion that drives human individuals to seek the esteem, approval, admiration, or love--the recognition--of their fellow beings. Neuhouser reconstructs Rousseau's understanding of what the drive for recognition is, why it is so problematic, and how its presence opens up far-reaching developmental possibilities for creatures that (...) possess it. One of Rousseau's central theses is that amour proper in its corrupted, manifestations--pride or vanity--is the principal source of an array of evils so widespread that they can easily appear to be necessary features of the human condition: enslavement, conflict, vice, misery, and self-estrangement. Yet Rousseau also argues that solving these problems depends not on suppressing or overcoming the drive for recognition but on cultivating it so that it contributes positively to the achievement of freedom, peace, virtue, happiness, and unalienated selfhood. Indeed, Rousseau goes so far as to claim that, despite its many dangers, the need for recognition is a condition of nearly everything that makes human life valuable and that elevates it above mere animal existence: rationality, morality, freedom--subjectivity itself--would be impossible for humans if it were not for amour proper and the relations to others it impels us to establish.

This paper traces the application of information theory to philosophical problems of mind and meaning from the earliest days of the creation of the mathematical theory of communication. The use of information theory to understand purposive behavior, learning, pattern recognition, and more marked the beginning of the naturalization of mind and meaning. From the inception of information theory, Wiener, Turing, and others began trying to show how to make a mind from informational and computational materials. Over the last 50 years, (...) many philosophers saw different aspects of the naturalization of the mind, though few saw at once all of the pieces of the puzzle that we now know. Starting with Norbert Wiener himself, philosophers and information theorists used concepts from information theory to understand cognition. This paper provides a window on the historical sequence of contributions made to the overall project of naturalizing the mind by philosophers from Shannon, Wiener, and MacKay, to Dennett, Sayre, Dretske, Fodor, and Perry, among others. At some time between 1928 and 1948, American engineers and mathematicians began to talk about `Theory of Information' and `Information Theory,' understanding by these terms approximately and vaguely a theory for which Hartley's `amount of information' is a basic concept. I have been unable to find out when and by whom these names were first used. Hartley himself does not use them nor does he employ the term `Theory of Transmission of Information,' from which the two other shorter terms presumably were derived. It seems that Norbert Wiener and Claude Shannon were using them in the Mid-Forties. (shrink)

The dorsal anterior cingulate cortex is a key node in the human salience network. It has been ascribed motor, pain-processing and affective functions. However, the dynamics of information flow in this complex region and how it responds to inputs remain unclear and are difficult to study using non-invasive electrophysiology. The area is targeted by neurosurgery to treat neuropathic pain. During deep brain stimulation surgery, we recorded local field potentials from this region in humans during a decision-making task requiring motor output. (...) We investigated the spatial and temporal distribution of information flow within the dACC. We demonstrate the existence of a distributed network within the anterior cingulate cortex where discrete nodes demonstrate directed communication following inputs. We show that this network anticipates and responds to the valence of feedback to actions. We further show that these network dynamics adapt following learning. Our results provide evidence for the integration of learning and the response to feedback in a key cognitive region. (shrink)

This chapter provides a critical reflection on an ethnographic approach led by a non-Indigenous researcher in partnership with an Indigenous community-controlled health organization, and a team of Indigenous and non-Indigenous supervisors, advisors, critical friends, and mentors. The chapter explores the way the three interrelated principles of Indigenist research informed the study, as a critical reflection of the methodology’s achievement of a decolonizing research agenda. The flow of Maiwah provides a metaphor for the chapter’s diverse authorship. Maiwah’s tributaries, inlets, and banks (...) represent author voices at different points while the one River flowing represents coming together to form a broader collective story of the research that still respects the authors’ individual positioning. Maiwah’s flow also signifies the dialogical approach of the research – “tricky ground” for non-Indigenous researchers seeking to privilege Indigenous voices while remaining accountable to their own White privilege, particularly given that at its most basic level, research requires the “extraction of ideas” from participants. Yet, the flow of Maiwah also shows us the possibilities of research, where in this case, researcher and participants together cocreated new knowledge in support of their agendas. This process enabled both research outcomes and increased research capacity and confidence in the host agency and researcher. On this account, decolonizing research is perhaps more about relationship and devolving control over the process than it is about particular methods, and the respectful negotiation of epistemological meanings and representation of particular knowledges that can result.

Consider predicates like 'is a fictional character' and 'is a mythical object'. Since their ascription entails a corresponding Negative Existential claim, call these 'NE-characterizing predicates'. Objectualists such as Parsons, Sylvan, van Inwagen, and Zalta think that NE-characterizing properties are genuine properties of genuinely non-existent objects. But how, then, to make room for statements like 'Vulcan is a failed posit' and 'that little green man is a trick of the light'? The predicates involved seem equally NE-characterizing yet on the surface fail (...) to mark a genuine property o f things. Instead, the truth of such predications strongly supervenes on types of referential failure. Kendall Walton's anti-objectualist account of talk about fiction provides a neat solution to this supervenience problem by invoking special games of make-believe. The present paper claims that while Walton's view thereby gains an important advantage over objectualism, the solution faces problems of its own. The rest of the paper desribes another solution, one that assigns a large role to the idea of metaphor. (shrink)

In the history of philosophy, Fichte's thought marks a crucial transitional stage between Kant and post-Kantian philosophy. Fichte radicalized Kant's thought by arguing that human freedom, not external reality, must be the starting point of all systematic philosophy, and in Foundations of Natural Right, thought by many to be his most important work of political philosophy, he applies his ideas to fundamental issues in political and legal philosophy, covering such topics as civic freedom, rights, private property, contracts, family relations, and (...) the foundations of modern political organization. This volume offers a complete translation of the work into English, by Michael Baur, together with an introduction by Frederick Neuhouser that sets it in its philosophical and historical context.
