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)

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.

Die Abhandlung betrachtet “Verantwortlichkeit für menschliches Handeln” als die quintessentielle Forderung der Aufklärung, welche Herder, nicht weniger als Thomasius und Kant, befürwortete. Was Herder, und diese Abhandlung, in Frage stellen, ist die enge Identifizierung des Aufklärungsbegriffes “Mündigkeit” mit Rationalität, Sittlichkeit, und Politik schlechthin.

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.

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.

For Hannah Arendt, spontaneous, ‘initiatory’ human action and interaction are suppressed by the normalizing pressures of society once ‘life’ - that is, sheer life - becomes the primary concern of politics, as it does, she finds, in the modern age. Arendt’s concept of the social is indebted to Martin Heidegger’s analysis of everyday Dasein in Being and Time , and contemporary political philosophers inspired by Heidegger, such as Jean-Luc Nancy, Philippe Lacoue-Labarthe, and Giorgio Agamben, tend to reproduce her account of (...) the withdrawal of the political in modernity. In this article, I complicate Arendt’s theory by turning to Michel Foucault’s parallel but diverging understanding of the nature of power in modern society to show, surprisingly, that Foucault’s narrative of the emergence of modern power pictures a society that is more, not less, politicized. Key Words: Hannah Arendt • bio-power • Michel Foucault • Philippe Lacoue-Labarthe • modernity • Jean-Luc Nancy • pastoral power • the social • rulership. (shrink)

The core of J.G. Herder's philosophy of nationalism lies in the conviction that human creativity must be embedded in the particular culture of a communal language. While he acknowledged that this cultural particular must be integrated into a more universal humanity, he insisted that each culture should preserve its incommensurable distinctiveness. He also called for a new method of enquiry regarding history, one that demands empathetic sensitivity toward the uniquely individual while realizing that there are few gains without losses. F.M. (...) Barnard demonstrates that Herder, despite his innovative work on the idea of nationality, was fully aware of the dangers of ethnic fanaticism, but also of the hazards of what is now known as globalization, recognizing that these must be tempered by a sense of universal humanity. Barnard shows that Herder anticipated modern theories of the dynamics of cultures and traditions through the problematic interplay of persistence and change and that his speculations on cultural and political pluralism, on language as a democratic bond, and on the possible fusion of communitarian and liberal dimensions of public life remain relevant to contemporary debates.

This is a critical discussion of the argument that since intentions are "logically connected" with their objects, Intentional actions cannot include intentions as their causes. Various versions of the argument are discussed, And it is argued that none of them shows the causal theory of intention to be inconsistent. It is argued that the causal theory is nevertheless wrong since intentions must be understood teleologically and as being, Therefore, Non-Contingently linked with actions.

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)

If Martin Heidegger was a philosopher who poetized, Wallace Stevens was a poet who philosophized. In "The Sail of Ulysses," one of his later poems, Stevens speaks enigmatically of a "right to be." The phrase is straightforward, if taken to indicate the right to life. But Stevens is rarely, if ever, straightforward. The poem is much more understandable if we take "being" in a Heideggerian sense, as an understanding of what it means to be.

The 21st century, otherwise unremarkable after the Great Climate Change Scare of its early decades was revealed to be a hoax, is remembered for its solution to an age-old problem.

Johann Gottfried Herder (1744-1803) has been called the German Rousseau. Yet while Rousseau is recognized as a political thinker, Herder is not. This book explores each thinker's ideas--on nature and culture, selfhood and mutuality, paternalism, freedom, and autonomy--and compares their conceptions of legitimate statehood. Arguing that the crux of political legitimacy for both men was the possibility of "extended selfhood," Barnard shows that Herder, like Rousseau, profoundly altered human self-understandings, thus influencing modes of justifying political allegiance.

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)
