In lieu of an abstract, here is a brief excerpt of the content:Buddhist-Christian Studies 22 (2002) 149-162 [Access article in PDF] Buddhist-Christian Complementarity in the Perspective of Quantum Physics Lai Pan-chiu Chinese University of Hong Kong Introduction The idea of Buddhist-Christian complementarity is by no means new. 1 But what is meant by "complementarity"? In quantum physics, the concept of "complementarity" has been extensively discussed due to the principle of complementarity introduced by Niels Bohr (1885-1962). (...) This principle is also one of the hotly debated issues in the areas of religion and natural science. Many scholars attempt to show that there are cases in Christian theology comparable to the complementarity in quantum physics. The most discussed case is perhaps the Christological doctrine of two natures in Jesus Christ. 2 Some scholars even attempt to interpret the relationship between theology and science in terms of complementarity. 3 This kind of discussion is not merely fanciful imagination originated by Christian theologians, since even Niels Bohr himself did advise Christian theologians to apply the complementary way of thinking in theology. 4 An interesting question may then be whether the principle of complementarity in quantum physics may cast light on the problem concerning Buddhist-Christian complementarity. This is the issue this essay attempts to address. Complementarity in Quantum Physics Modern physics, especially the theory of relativity and quantum physics, as Werner Heisenberg pointed out, brings forth to us an important philosophical issue—the relationship between language and reality. Some modern physicists find that they have to make use of ordinary language to establish a visual understanding or presentation of some events, which can hitherto only be expressed by a bundle of mathematical formulae. However, the ordinary language, together with its derived concepts, used in classical physics cannot adequately interpret some of the discoveries of modern physics. For example, conventional concepts of time and space can no longer apply directly in the general theory of relativity. The inadequacy of the classical concepts of "wave" and "particle" in quantum physics is another illustrative case. According to Bohr's theory, physicists can make use of these classical concepts in a [End Page 149] loose way, even though these concepts may seem to contradict each other when applied together. 5The principle of complementarity proposed by Niels Bohr refers specifically to the use of the two seemingly contradictory concepts in classical physics—"particle" and "wave"—to explain the behavior of a particular entity, light. Wave and particle are mutually exclusive concepts in classical physics. According to the classical understanding, wave possesses some characteristics that particle does not have, such as reflection, refraction, diffusion and interference. In reverse, particle also possesses some characteristics that wave does not have, such as occupying certain space. However, quantum physicists have discovered that in some experiments, light "behaves" as wave, whereas in others it behaves as particle. The results of experiments seem to suggest that neither "wave" nor "particle" can adequately explain the quantum phenomena. For this reason, some physicists, including Albert Einstein, suggest abandoning the use of the concepts of wave and particle in the subatomic realm. Contrary to this view, Bohr insists that the concepts of "wave" and "particle" remain usable and useful in quantum physics because "however far the phenomena transcend the scope of classical physical explanation, the account of all evidence must be expressed in classical terms." 6 As Bohr puts it, "the fundamental postulate of the indivisibility of the quantum of action is itself, from the classical point of view, an irrational element which inevitably requires us to forego a causal mode of description and which, because of the coupling between phenomena and their observation, forces us to adopt a new mode of description designated as complementary in the sense that any given application of classical concepts precludes the simultaneous use of other classical concepts which in a different connection are equally necessary for the elucidation of the phenomena." 7The principle of complementarity can thus be understood as a method or "mode of description" using two or more mutually exclusive concepts of a specific realm (classical physics) to explain a phenomenon of another realm (quantum physics) that...

This paper issues a call to arms and seeks to entice the reader with some of the most captivating philosophical puzzles arising in quantum gravity. The analysis will be prefaced, in Section 1, by general considerations concerning the need for finding a quantum theory of gravity and the methods used in the pursuit of this goal. After mapping the field in Section 2, loop quantum gravity is introduced as an important competitor and particularly rich source of (...) philosophical trouble in Section 3. The so-called problem of time, i.e. the puzzle that no genuine physical quantity can change, is discussed in Section 4. Finally, Section 5 analyzes how the familiar continuous spacetime structure might re-emerge from the fundamental, non-spatiotemporal structure. (shrink)

We interpret the philosophy of Niels Bohr as related to the so called ''linguistic turn'' and consider paraconsistency in the light of the Bohrian notion of complementarity. Following [16], Jean-Yves Beziau has discussed the seemingly contradictory perspectives found in the quantum mechanical double slit experiment in terms of paraconsistent view-points [7, 8]. This interpretation goes in line with the well known Bohrian Neo-Kantian epistemological account of quantum mechanics. In the present paper, we put forward the idea that (...) one can also consider, within quantum mechanics and departing from the philosophy of the danish physicist, a more radical paraconsistency found within one of the main formal elements of the theory, namely, quantum superpositions. We will argue that, rather than epistemological, the contradictions found within quantum superpositions could be interpreted as ontological contradictions. (shrink)

J. Baird Callicott seeks to resolve the problem of the intrinsic value of nature by utilizing a nondualistic paradigm derived from quantum theory. His approach is twofold. According to his less radical approach, quantum theory shows that properties once considered to be “primary” and “objective” are in fact the products of interactions between observer and observed. Values are also the products of such interactions. According to his more radical approach, quantum theory’s doctrine of internal relations is (...) the model for the idea that everything is intrinsically valuable because the “I” is intrinsically valuable and related to everything else. I argue that humanity’s treatment of nature will become respectful only as humanity’s awareness evolves toward nondualism, and that such nondualistic awareness will not be produced by changes in scientific theory alone. Nevertheless, as Callicott suggests, such changes may be harbingers of evolutionary trends in human awareness. I conclude with a sketch of how nondualism, especially in its panentheistic version, provides the basis for environmental ethics. (shrink)

This essay offers a reaction to the recent resurgence of presentism in the philosophy of time. What is of particular interest in this renaissance is that a number of recent arguments supporting presentism are crafted in an untypically naturalistic vein, breathing new life into a metaphysics of time with a bad track record of co-habitation with modern physics. Against this trend, the present essay argues that the pressure on presentism exerted by special relativity and its core lesson of (...) Lorentz symmetry cannot easily be shirked. A categorization of presentist responses to this pressure is offered. As a case in point, I analyze a recent argument by Monton (2006) presenting a case for the compatibility of presentism with quantum gravity. Monton claims that this compatibility arises because there are quantum theories of gravity that use fixed foliations of spacetime and that such fixed foliations provide a natural home for a metaphysically robust notion of the present. A careful analysis leaves Monton's argument wanting. In sum, the prospects of presentism to be alleviated from the stress applied by fundamental physics are faint. (shrink)

Quantum theory is a tremendously successful physical theory, but nevertheless suffers from two serious problems: the measurement problem and the problem of interpretational underdetermination. The latter, however, is largely overlooked as a genuine problem of its own. Both problems concern the doctrine of realism, but pull, quite curiously, into opposite directions. The measurement problem can be captured such that due to scientific realism about quantum theory common sense anti-realism follows, while theory underdetermination usually counts as an argument (...) against scientific realism. I will also consider the more refined distinctions of ontic and epistemic realism and demonstrate that quantum theory in its most viable interpretations conflicts with at least one of the various realism claims. A way out of the conundrum is to come to the bold conclusion that quantum theory is, possibly, wrong (in the realist sense). (shrink)

In this paper, I will present an argument against Husserl’s analysis of picture consciousness. Husserl’s analysis of picture consciousness (as it can be found primarily in the recently translated volume Husserliana 23) moves from a theory of depiction in general to a theory of perceptual imagination. Though, I think that Husserl’s thesis that picture consciousness is different from depictive and linguistic consciousness is legitimate, and that Husserl’s phenomenology avoids the errors of linguistic theories, such as Goodman’s, I submit that his (...) overall theory is unacceptable, especially when it is applied to works of art. Regarding art, the main problem of Husserl’s theory is the assumption that pictures are constituted primarily as a conflict between perception/physical picture thing and imagination/picture object. Against this mentalist claim, I maintain, from a hermeneutic point of view, that pictures are the result of perceptual formations [Bildungen]. I then claim that Husserl’s theory fails, since it does not take into account what I call “plastic perception” [Bildliches Sehen], which plays a prominent role not only within the German tradition of art education but also within German art itself. In this connection, “plastic thinking” [Bildliches Denken] was prominent especially in Klee, in Kandinsky, and in Beuys, as well as in the overall doctrine of the Bauhaus. Ultimately, I argue that Husserl’s notion of picture consciousness and general perceptive imaginary consciousness must be replaced with a more dynamic model of the perception of pictures and art work that takes into account (a) the constructive and plastic moment, (b) the social dimension and (c) the genetic dimension of what it means to see something in something (Wollheim).

What is the task of educational theory or philosophy if it is not merely conceived as specification of philosophical doctrines in the realm of education? In my view it is the particular task of educational-philosophical theory to work critically on the historically developed cultural constructs that shape our (educational) experience. Thus, the activity that educational theorists are to perform is the critical reflection of the “limits of our world” by drawing on philosophical references and theories. In this text I describe (...) this activity drawing from my own research practice with a particular focus on its relation to what is called thinking. (shrink)

Hilary Putnam has argued that from a realist perspective, quantum mechanics stands in need of an interpretation. Ironically, this hypothesis may appear vulnerable against arguments drawing on Putnam's own work. Nancy Cartwright has urged that his 1962 essay on the meaning of theoretical terms suggests that quantum mechanics needs no interpretation and thus stands in tension with his claim of three years later. She furthermore contends that this conflict should be resolved in favour of the earlier work, (...) as quantum mechanics, like all successful theories, does not need an interpretation. The first part of this essay deflates both of these objections. The second part addresses and evaluates Putnam's own assessments of the main interpretative options available in 1965 and 2005. Although we may disagree on some aspects, his pessimistic conclusion will come out largely unscathed, and, in fact, enhanced. I will close by briefly stating the historical relevance of this work.

This is a chapter of the planned monograph "Out of Nowhere: The Emergence of Spacetime in Quantum Theories of Gravity", co-authored by Nick Huggett and Christian Wüthrich and under contract with Oxford University Press. (More information at www<dot>beyondspacetime<dot>net.) This chapter introduces causal set theory and identifies and articulates a 'problem of space' in this theory.

A local, deterministic, and realistic model within a Friedmann-Robertson-Walker spacetime with constant spatial curvature is presented which describes simultaneous measurements of the spins of two fermions emerging in a singlet state from the decay of a spinless boson. Exact agreement with the probabilistic predictions of quantum theory is achieved in the model without data rejection, remote contextuality, superdeterminism, or backward causation. An event-by-event numerical simulation of the model is presented, which confirms our analytical results with the (...) accuracy of 4 in 10,000 parts. (shrink)

In this paper we derive a theorem which proves that the physical interpretation implied by the first postulate of quantum mechanics is inconsistent with the orthodox formalism. In order to expose this inconsistency we will analyze how the concept of ‘physical system’ is built within classical theories through the notion of invariance and explain in what sense a vector in Hilbert space is not capable of fulfilling these same mathematical conditions. Through an analysis of the mathematical formalism we (...) derive a No Dynamical Invariance theorem which proves that, contrary to what is claimed in the first postulate, a vector in Hilbert space cannot be interpreted coherently as the state of a physical system. We conclude the paper by analyzing the consequences of the NDI theorem with respect to several ongoing debates in QM. (shrink)

Ernest Barnes was invited to Aberdeen as Gifford Lecturer (1927-1929) to deliver lectures under the title of 'Scientific Theory and Religion'. The lectures were originally published in 1933 and sought to bring Christian doctrines together with the possibility of life on other planets. The magnitude of the universe, accompanied with some basic observations on biological development within it, makes speculation about the possibility of intelligent life in distant galaxies reasonable. Barnes believed that the Creation was made precisely (...) for the higher forms of' consciousness. The scope of the background to scientific theory and religious ideas of creation presented here is extensive and covers topics including Jewish cosmology as the basis for later Christian thought to early quantum mechanics and evolutionary biology. However, as Barnes himself noted of this scope in his lectures, 'Wide as is their range, they have an inner coherence. I trust that they express the attitude of the modern man of science who, as he hopefully makes theories, is aware of the limitations of his knowledge and also, in part because of his loyalty to truth, bears in mind the reality and the claims of the spiritual world.'.

Quantum theory is perhaps our best confirmed theory for a description of the physical properties of nature. On top of demonstrating great empirical effectiveness, many technological developments in the 20th century (such as the interpretation of the periodic table of elements, CD players, holograms, and quantum state teleportation) were only made possible with Quantum theory.Despite its success in the past decades, even today it still remains without a universally accepted interpretation.This book provides an interdisciplinary perspective on (...) the question; 'What is Quantum Mechanics talking about?', a question which continues to be one of the most fascinating and important questions in science.Using an interdisciplinary approach to foundational problems in Quantum Mechanics (QM), ranging from philosophical questions about the interpretation of QM to technical problems in quantum computation, this book explores quantum mechanics from different perspectives (physical, logical, philosophical and mathematical), by researchers from Europe, North America, and South America.

Perhaps no other classical philosophical tradition, East or West, offers a more complex and counter-intuitive account of mind and mental phenomena than Buddhism. While Buddhists share with other Indian philosophers the view that the domain of the mental encompasses a set of interrelated faculties and processes, they do not associate mental phenomena with the activity of a substantial, independent, and enduring self or agent. Rather, Buddhist theories of mind center on the doctrine of no-self (Pāli anatta, Skt.[1] (...) anātma), which postulates that human beings are reducible to the physical and psychological constituents and processes which comprise them.

Many attempts have been made to provide Quantum Field Theory with conceptually clear and mathematically rigorous foundations; remarkable examples are the Bohmian and the algebraic perspectives respectively. In this essay we introduce the dissipative approach to QFT, a new alternative formulation of the theory explaining the phenomena of particle creation and annihilation starting from nonequilibrium thermodynamics. It is shown that DQFT presents a rigorous mathematical structure, and a clear particle ontology, taking the best from the mentioned perspectives. Finally, (...) after the discussion of its principal implications and consequences, we compare it with the main Bohmian QFTs implementing a particle ontology. (shrink)

Quantum gravity--the marriage of quantum physics with general relativity--is bound to contain deep and important lessons for the nature of physical time. Some of these lessons shall be canvassed here, particularly as they arise from quantum general relativity and string theory and related approaches. Of particular interest is the question of which of the intuitive aspects of time will turn out to be fundamental, and which 'emergent' in some sense.

We assess John Bishop’s theory of the nature of Christian faith in God, as most recently expressed in ‘Reasonable Faith and Reasonable Fideism’, although we dip into other writings as well. We explain several concerns we have about it. However, in the end, our reflections lead us to propose a modified theory, one that avoids our concerns while remaining consonant with some of his guiding thoughts about the nature of Christian faith in God. We also briefly examine (...) three normative issues Bishop’s views present. (shrink)

This paper first examines surviving testimonies on the doctrine of the Great Year in Heraclitus and attempts to demonstrate the reliability of Aëtius’ version handed down by the mss., according to which the Great Year is equal to 18,000 solar years. On the basis of such evidence it is also possible to newly examine Diogenes of Babylon’s views about this topic. In the second part, the paper better defines the relationship between the Great Year and the theory of cosmic (...) conflagration. It argues that in the sources at our disposal there are enough elements to credit Heraclitus with the doctrine of Ekpyrosis, although, in all probability, the philosopher never provided an in-depth description of it. Finally, the same problem is analysed in relation to Diogenes of Babylon. In the most mature phase of his career, this Stoic departed from the Ekpyrosis doctrine of the early Stoics and especially of his master Chrysippus. The paper formulates some hypotheses on the reasons for this choice (arguing that it most probably reflects an original attitude towards Heraclitus on Diogenes’ part) and highlights that it was hardly an isolated, ‘heterodox’ stance during the final phase of the early Stoa.

In this paper we analyze and discuss the historical and philosophical development of the notion of logical possibility focusing on its specific meaning in classical and quantum mechanics. Taking into account the logical structure of quantum theory we continue our discussion regarding the Aristotelian Square of Opposition in orthomodular structures enriched with a monadic quantifier. Finally, we provide an interpretation of the Orthomodular Square of Opposition exposing the fact that classical possibility and quantum possibility behave formally (...) in radically different manners.

The concept of classical r matrices is developed from a purely canonical standpoint. The final purpose of this work is to bring about a synthesis between recent developments in the theory of integrable systems and the general theory of quantization as a deformation of classical mechanics. The concept of quantization algebra is here dominant; in integrable systems this is the set of dynamical variables that appear in the Lax pair. The nature of this algebra, a solvable Lie algebra in such (...) models as the Sine-Gordon and Toda field theories but semisimple in the case of spin systems, provides a useful scheme for the classification of integrable models. A completely different classification is obtained by the nature of the r matrix employed; there are three kinds: rational, trigonometric, and elliptic. All cases are studied in detail, with numerous examples. Some of the problems connected with quantization are discussed. (shrink)

The meaning and validity of Kant’s Kant’s doctrine of schematism remains contested until today. In neo-Kantianism and post-War transcendental philosophy, Kant’s schematism of the pure concepts of understanding is transformed drastically. Kant’s thesis of heterogeneity is overcome by taking it back into the internal relationships of the structure of cognition. The spontaneity of thought, performing schematizations, is retained, but Kant’s project of conceiving of the foundations of knowledge in the fashion of a theory of apperception of the I as (...) well as the externality of the given and the determination of the given that goes along with it is sublated by an objective order of validity-noematic constitution and regulation. Kant’s doctrine of schematism, then, shows to be methodology. (shrink)

More often than not, recently popular structuralist interpretations of physical theories leave the central concept of a structure insufficiently precisified. The incipient causal sets approach to quantum gravity offers a paradigmatic case of a physical theory predestined to be interpreted in structuralist terms. It is shown how employing structuralism lends itself to a natural interpretation of the physical meaning of causal set theory. Conversely, the conceptually exceptionally clear case of causal sets is used as a foil to illustrate how (...) a mathematically informed rigorous conceptualization of structure serves to identify structures in physical theories. Furthermore, a number of technical issues infesting structuralist interpretations of physical theories such as difficulties with grounding the identity of the places of highly symmetrical physical structures in their relational profile and what may resolve these difficulties can be vividly illustrated with causal sets.

Approaches to quantum gravity often involve the disappearance of space and time at the fundamental level. The metaphysical consequences of this disappearance are profound, as is illustrated with David Lewis's analysis of modality. As Lewis's possible worlds are unified by the spatiotemporal relations among their parts, the non-fundamentality of spacetime---if borne out---suggests a serious problem for his analysis: his pluriverse, for all its ontological abundance, does not contain our world. Although the mere existence---as opposed to the fundamentality---of spacetime (...) must be recovered from the fundamental structure in order to guarantee the empirical coherence of the non-spatiotemporal fundamental theory, it does not suffice to salvage Lewis's theory of modality from the charge of rendering our actual world impossible.

Suppose that the members of a group each hold a rational set of judgments on some interconnected questions, and imagine that the group itself has to form a collective, rational set of judgments on those questions. How should it go about dealing with this task? We argue that the question raised is subject to a difficulty that has recently been noticed in discussion of the doctrinal paradox in jurisprudence. And we show that there is a general impossibility theorem that (...) that difficulty illustrates. Our paper describes this impossibility result and provides an exploration of its significance. The result naturally invites comparison with Kenneth Arrow's famous theorem (Arrow, 1963 and 1984; Sen, 1970) and we elaborate that comparison in a companion paper (List and Pettit, 2002). The paper is in four sections. The first section documents the need for various groups to aggregate its members' judgments; the second presents the discursive paradox; the third gives an informal statement of the more general impossibility result; the formal proof is presented in an appendix. The fourth section, finally, discusses some escape routes from that impossibility. (shrink)

I demonstrate that Bell's theorem is based on circular reasoning and thus a fundamentally flawed argument. It unjustifiably assumes the additivity of expectation values for dispersion-free states of contextual hidden variable theories for non-commuting observables involved in Bell-test experiments, which is tautologous to assuming the bounds of ±2 on the Bell-CHSH sum of expectation values. Its premises thus assume in a different guise the bounds of ±2 it sets out to prove. Once this oversight is ameliorated from Bell's argument by (...) identifying the impediment that leads to it and local realism is implemented correctly, the bounds on the Bell-CHSH sum of expectation values work out to be ±2√2 instead of ±2, thereby mitigating the conclusion of Bell's theorem. Consequently, what is ruled out by any of the Bell-test experiments is not local realism but the linear additivity of expectation values, which does not hold for non-commuting observables in any hidden variable theories to begin with. I also identify similar oversight in the GHZ variant of Bell's theorem, invalidating its claim of having found an inconsistency in the premisses of the argument by EPR for completing quantum mechanics. Conceptually, the oversight in both Bell's theorem and its GHZ variant traces back to the oversight in von Neumann's theorem against hidden variable theories identified by Grete Hermann in the 1930s.

In a recent paper on ‘The Many as One’, Lewis A. Kornhauser and Lawrence G. Sager look at an issue that we take to be of great importance in political theory. How far should groups in public life try to speak with one voice, and act with one mind? How far should public groups try to display what Ronald Dworkin calls integrity? We do not expect the many on the market to be integrated in this sense. But should (...) we expect integration among the many in the legislature, for example, or among the many on the courts? We agree with Kornhauser and Sager about a number of their claims but think that they miss out on important detail and do not achieve a fully general perspective on the issues raised. Our own contribution is in three sections. We address, first, the nature of the integrity challenge; second, the range of cases in which the challenge arises; and third, the question of whether public groups should be designed and required to meet that challenge.

Information theory presupposes the notion of an epistemic agent, such as a scientist or an idealized human. Despite that, information theory is increasingly invoked by physicists concerned with fundamental physics, physics at very high energies, or generally with the physics of situations in which even idealized epistemic agents cannot exist. In this paper, I shall try to determine the extent to which the application of information theory in those contexts is legitimate. I will illustrate my considerations using the (...) case of black hole thermodynamics and Bekenstein's celebrated argument for his formula for the entropy of black holes. This example is particularly pertinent to the theme of the present collection because it is widely accepted as `empirical data' in notoriously empirically deprived quantum gravity, even though the laws of black hole thermodynamics have so far evaded direct empirical confirmation.

Recent years have seen a growing consensus in the philosophical community that the grandfather paradox and similar logical puzzles do not preclude the possibility of time travel scenarios that utilize spacetimes containing closed timelike curves. At the same time, physicists, who for half a century acknowledged that the general theory of relativity is compatible with such spacetimes, have intensely studied the question whether the operation of a time machine would be admissible in the context of the same theory and (...) of its quantum cousins. A time machine is a device which brings about closed timelike curves—and thus enables time travel—where none would have existed otherwise. The physics literature contains various no-go theorems for time machines, i.e., theorems which purport to establish that, under physically plausible assumptions, the operation of a time machine is impossible. We conclude that for the time being there exists no conclusive no-go theorem against time machines. The character of the material covered in this article makes it inevitable that its content is of a rather technical nature. We contend, however, that philosophers should nevertheless be interested in this literature for at least two reasons. First, the topic of time machines leads to a number of interesting foundations issues in classical and quantum theories of gravity; and second, philosophers can contribute to the topic by clarifying what it means for a device to count as a time machine, by relating the debate to other concerns such as Penrose's cosmic censorship conjecture and the fate of determinism in general relativity theory, and by eliminating a number of confusions regarding the status of the paradoxes of time travel. The present article addresses these ambitions in as non-technical a manner as possible, and the reader is referred to the relevant physics literature for details. (shrink)

It is argued that the `problem of time' in quantum gravity necessitates a refinement of the local inertial structure of the world, demanding a replacement of the usual Minkowski line element by a 4+2n dimensional pseudo-Euclidean line element, with the extra 2n being the number of internal phase space dimensions of the observed system. In the refined structure, the inverse of the Planck time takes over the role of observer-independent conversion factor usually played by the speed of light, (...) which now emerges as an invariant but derivative quantity. In the relativistic theory based on the refined structure, energies and momenta turn out to be invariantly bounded from above, and lengths and durations similarly bounded from below, by their respective Planck scale values. Along the external timelike world-lines, the theory naturally captures the `flow of time' as a genuinely structural attribute of the world. The theory also predicts expected deviations---suppressed quadratically by the Planck energy---from the dispersion relations for free fields in the vacuum. The deviations from the special relativistic Doppler shifts predicted by the theory are also suppressed quadratically by the Planck energy. Nonetheless, in order to estimate the precision required to distinguish the theory from special relativity, an experiment with a binary pulsar emitting TeV range gamma-rays is considered in the context of the predicted deviations from the second-order shifts.

The theory of Lebesgue and Sobolev spaces with variable integrability is experiencing a steady expansion, and is the subject of much vigorous research by functional analysts, function-space analysts and specialists in nonlinear analysis. These spaces have attracted attention not only because of their intrinsic mathematical importance as natural, interesting examples of non-rearrangement invariant function spaces but also in view of their applications, which include the mathematical modeling of electrorheological fluids and image restoration.The main focus of this book is to (...) provide a solid functional analytic background for the study of differential operators on spaces with variable integrability. It includes some novel stability phenomena which the authors have recently discovered.At the present time, this is the only book which focuses systematically on differential operators on spaces with variable integrability. The authors present a concise, natural introduction to the basic material and steadily move toward differential operators on these spaces, leading the reader quickly to current research topics.

São muitas e, até hoje, muito controvertidas as opiniões referentes à função e ao lugar sistemático da filosofia da história de Kant no todo do seu projeto crítico-transcendental; nem há consenso quanto à importância ou relevância filosófica dos diversos escritos em que Kant aborda e defende os seus teoremas histórico- políticos. – No presente trabalho, pretende-se interpretar a “doutrina” histórico-filosófica kantiana – não obstante o seu caráter fragmentário e até aparentemente nem sempre coerente – na perspectiva da sua possível homogeneidade (...) e compatibilidade com os elementos centrais da própria teoria-base transcendental. Isso significa, antes de mais nada, ler os respectivos teoremas não como resultados de um raciocínio dogmático baseado num saber do processo histórico, mas como um conjunto de teses e postulados baseados no mero suposto subjetivo-racional de um progresso, ou seja, na idéia não só da possibilidade mas da necessidade (subjetiva) da razão de implantar princípios racionais na história.

ABSTRACT There are many different and controversial opinions about the function and the systematic place of Kant’s philosophy of history in the context of his critical-transcendental project on the whole, as well as about the philosophic relevance of his historical-political writings. – This paper aims to interpret Kant’s historical-philosophical “doctrine” – in despite of its fragmentary character and of some apparent incoherences – in the horizon of its possible homogeneity and compatibility with the central elements of the basic transcendental theory. That means, above all: read the theorems in question not as results of a dogmatic thought based on the knowledge of historical processes, but as a set of thesis and postulates based on the mere subjective- rational supposition of progress, that is, on the idea that it is not only possible, but a (subjective) need of reason to implant rational principles in history.

Such policies, he posits, would not only achieve a more comprehensive agenda of peacemaking but would also approach more closely the vision of Dr. Martin Luther King Jr.'s "Beloved Community."McCarthy's project is ambitious and multifaceted. He sets out to synthesize critiques of prevailing rule- and strategy-based assessments of nonviolent [End Page 204] peacemaking, making proposals for a virtue-based assessment from Christian, Hindu, and Muslim sources as well as with the best contributions of human rights theory in order to supplement a virtue approach. At the outset he states, "My thesis is that a virtue-based assessment of nonviolent peacemaking enhanced by aspects of human rights discourse largely resolves key limits of rule-based and strategy-based assessments of nonviolent peacemaking for public discourse and policy" (2). To prove this, he grapples with influential scholars on the subject, such as James Childress and Gene Sharp, to show how deontology and consequentialism too narrowly constrain the vision of what nonviolent peacemaking can achieve, both in effect and the formation of agents' character. Addressing the work of Bernard Häring, Stanley Hauerwas, and Lisa Sowle Cahill, he brings the fruit of Christian theological ethics to bear on the advantages of a virtue-based assessment of nonviolence. Though that is significant enough, McCarthy also presents the life and work of both Mahatma Gandhi and Abdul Ghaffar Khan to demonstrate the consonance of a virtue approach even across cultural and religious lines. He finally plots a way forward using the best of rights theory and virtue theory to show how nonviolent peacemaking fulfills the Catholic social tradition's vision of human dignity and the common good.McCarthy lends much to the argument that "we ought to consider nonviolent peacemaking a distinct virtue rather than merely subsuming it in the paradigmatic actions of other virtues" (75). With scripture at its foundation and positioned within the traditions of virtue ethics and the Catholic social doctrine, he weaves a tight argument for nonviolence within a Christian context while also aiming to be approachable and sympathetic to non-Christian perspectives. Because of the contemporary context of McCarthy's project, he does focus his attention almost exclusively on twentieth- and twenty-first-century sources; it would be helpful to be already familiar with virtue ethics and its classic sources, like Aristotle, Cicero, and Aquinas.McCarthy writes clearly and directly to readers, making the schema of his argument explicit in each chapter. His extensive referencing and ample bibliography engage both academic research and popular journalism, making this a great resource for those pursuing public theology and students in advanced undergraduate and professional study. His last chapter, which provides a case study regarding the Sudanese genocide in Darfur, applies his peacemaking proposals in a compelling thought experiment. One can hope McCarthy's continued research yields not only more case studies that invite creative problem-solving through the virtue of nonviolent peacemaking but also a book-length study that challenges US domestic policy as successfully as his investigation of US foreign policy here.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 40.1 (2002) 126-127 [Access article in PDF] Book Review Natural Law Theories in the Early Enlightenment T. J. Hochstrasser. Natural Law Theories in the Early Enlightenment. New York: Cambridge University Press, 2000. Pp. xiii + 246. Cloth, $54.95. In a worthy addition to Cambridge's Ideas in Context series, T. J. Hochstrasser undertakes an excavation. His aim is to provide a description, and to (...) demonstrate the importance within the German Frühaufklärung, of a largely forgotten philosophical approach: eclecticism. Hochstrasser argues that the triumph of Wolffian rationalism in the Protestant universities in the middle of the eighteenth century occluded the importance of eclecticism for Kant, who in turn occluded it for everyone afterward. But the price of forgetting eclecticism is high. Not only are we left with no account--or a skewed account--of the development of German thought from the first stirrings of the Enlightenment to the emergence of the Critical philosophy, but our understanding of the development of the historiography of philosophy is badly compromised. For among their many accomplishments--in natural jurisprudence, in university reform--the eclectics were the first critical historians of philosophy, their distinctive genres being historically aware treatises on natural law and Whig histories of natural jurisprudence. Hochstrasser's study traces the development of eclecticism, from the work of its founders, Samuel Pufendorf and Christian Thomasius, through a devolution in the hands of Thomasius's later disciples, to the eventual oblivion in the middle of the eighteenth century. This review will focus on the beginning of this narrative, as Pufendorf is the leading figure in the book.Eclecticism began with Pufendorf's attempt, in his mature work on natural law, to reconcile his conflicting inheritances from Grotius and Hobbes without simply endorsing the work of either. He was impressed both by Grotius's explanation of the law of nations in terms of human sociability--but also by Hobbes's criticisms of Grotius, rooted in the latter's analysis of the state of nature. At the same time, he wished to reject Grotius's method of induction from sociological observation and Hobbes's minimally constrained voluntarism. Contributing further to his perplexity was his increasing disaffection from the geometric approach he had adopted in his Elementa Jurisprudentiae Universalis.The way out of this impasse, Hochstrasser contends, was revealed to Pufendorf in correspondence with Hermann Conring, the leading constitutional lawyer of his time, and Johann Böcler, Grotius's most erudite commentator. Böcler chastised Pufendorf for his neglect of history, and both of Pufendorf's correspondents pointed out his need for some non-Hobbesian criterion by which he could validate his first principles, whatever they turned out to be. Stung particularly by Böcler's remarks, Pufendorf returned to the Stoics and there discovered a via media between Hobbes's pessimism and Grotius's optimism: a synthesis anticipating Kant's doctrine of "unsocial sociability." For the purposes of Hochstrasser's study, the key aspects of Pufendorf's solution are these: first, it avoids mere voluntarism; second, it does this by means of a moral epistemology that sharply distinguishes natural law [End Page 126] from moral theology; finally, the validating criterion for Pufendorf's first principles is located in critical appropriation of the history of moral philosophy. These were to be hallmarks of Pufendorf's school.On the first and second points, Hochstrasser seems to me substantively correct, though I think he misunderstands the nature of Pufendorf's escape from mere voluntarism and thereby underplays the religious dimensions of Pufendorf's theory. Among recent Anglo-American commentators on Pufendorf, only Robert Adams has in my view properly construed Pufendorf's thought: that it involves a command theory of obligation proper, but posits the natural advantageousness of some hierarchies as a buttress against mere voluntarism. Hochstrasser is thus right to insist, against Leibniz, that Pufendorf's account of obligation is coherent. But he is wrong to suggest that "there was nothing in Pufendorf's theory... to oblige him to introduce fear of punishment by a superior... " (105). He is... (shrink)

In this paper we address a deeply interesting debate that took place at the end of the last millennia between David Mermin, Adan Cabello and Michiel Seevinck, regarding the meaning of relationalism within quantum theory. In a series of papers, Mermin proposed an interpretation in which quantum correlations were considered as elements of physical reality. Unfortunately, the very young relational proposal by Mermin was too soon tackled by specially suited no-go theorems designed by Cabello and Seevinck. In this (...) work we attempt to reconsider Mermin's program from the viewpoint of the Logos Categorical Approach to QM. Following Mermin's original proposal, we will provide a redefinition of quantum relation which not only can be understood as a preexistent element of physical reality but is also capable to escape Cabello’s and Seevinck's no-go-theorems. In order to show explicitly that our notion of ontological quantum relation is safe from no-go theorems we will derive a non-contextuality theorem. We end the paper with a discussion regarding the physical meaning of quantum relationalism. (shrink)

On several levels, there is now a debate whether the concept of God can be made compatible with modern science. In an attempt to elucidate this debate, I give an account of my own experiences from writing a book on the foundation of quantum mechanics. In my opinion, one can give two independent arguments for the existence of God by taking as departure an epistemic (knowledge-based) interpretation of quantum theory. However, I also argue that any religious belief (...) should be the result of an existential choice governed by each person’s own context (history and culture). In particular, I give my account of Christianity as a religion connected to our western culture, how one as a scientist can relate to the relevant dogmas. (shrink)

continent. 1.4 (2011): 279—285. Concerning its Transitive Nature, the Conversion of Native Americans of Spanish Colonial California, Indoctrinated Catholicism, & the Creation There’s no direct archaeological evidence that Jesus ever existed. 1 I memorized the Act of Contrition. I don’t remember it now, except the beginning: Forgive me Father for I have sinned . . . This was in preparation for the Sacrament of Holy Reconciliation, where in a confessional I confessed my sins to Father Scott, who looked like Jesus, (...) at least in Western cultural representations of Jesus since the middle ages, and if Jesus put on a few pounds. Father Scott was long-haired, redheaded, bearded, chubby, and tall. When he left church with the procession of altar servers and Eucharistic ministers, yelling, “Sing a Good Song Unto the Lord,” he smiled, hands folded, and he gazed over his parishioners, and bounced along. For four months every year he lived among the Crow Nation in Montana, where towards the end of his tenure at Our Lady of Refuge, they adopted him as an honorary member of their tribe. * This is the prayer we chanted, holding hands, every night before dinner: Bless us oh Lord, for these our gifts, which we are about to receive, our bounty through Christ, our Lord, Amen. Then we all said, God bless the cook! When we were with my grandparents, Grandpa said, God bless Chicky, and Holly, and Harvey, and Boots—all the dead dogs. * My sister tells me that she sits next to a handsome man on a flight across the country. After chitchat, she withdraws her book. She’s reading Kevin Sampsell’s A Common Pornography . After a few moments, the handsome man also reads from his book—his leather-bound Bible. Sister thinks, Oh, Jesus—too bad. She falls asleep. Later, settled in Nashville, she opens her volume and out falls a Jesus-covered card that reads, You can still find God and Salvation! Because that handsome God-fearing young man saw that word— pornography . * I suppose Father Jim’s dark hair, beard, and glasses made me think doctoral-ly of him. He called while I was in the midst of a breakup, after I’d twice attempted suicide, and my mother was desperate for help. She somehow found and phoned him. And Jim, now years out of Our Lady of Refuge’s parish, twenty years since my baptism, years even since he’d left the priesthood and the Catholic faith, still made the effort to bring me back into the fold. He said, “Have you seen a priest?” I did not respond, as I was more shocked to hear his voice than anything, so I said, “How are you, Father Jim? Sorry, I guess I shouldn’t call you ‘Father.’” And I said, “Why did you leave the priesthood? Do you have a girlfriend?” He said that I should call him just “Jim.” He said, “Do you need someone to talk to?” I said, “Not really.” He said, “Call your mother; she’s worried about you.” That was the last time I talked to Father Jim. * Mother let me know just how disappointed Jesus was. I cried and cried, and said I was sorry. Into my hands she placed my missal, ordered forty Rosaries. She said next Saturday I would go to confession. I hated confession. Who wouldn’t? * I realize, of course, that this page is a kind of confessional. * The Kumeyaay, Ipai, Tipai, Chumash, Esselen, Rumsen—all Native Americans of Alta California—shared similarities in their religions. Southern Californian tribes made use of Datura, or jimpson weed, a hallucinogen, for religious rituals. In the creation, God made brother sky and sister earth. Brother and sister mated, and sister gave birth to all things on Earth, including people, but it was difficult to distinguish people from all other aspects of Earth because everything was alive: granite and obsidian, the Pacific and its waves, the San Diego and Los Angeles Rivers. Wiyot—a hero—was very powerful, born from lightning, the son of the Creator and a virgin. When Wiyot thought that human women’s legs were more beautiful than Frog’s, Frog became jealous and poisoned Wiyot. The dying Wiyot went to all the people’s villages, and he distributed his power among them. He said, “When I die, I should be cremated.” The people built the fire and funeral pyre. When the fire was ready, and the people about to place Wiyot’s body upon it, Coyote came and snatched away Wiyot’s heart. * My friend Nick told me once how he ate some jimpson weed and that he hallucinated for three days. His family took a road trip and, while driving over the Sierra Nevada mountains, he kept seeing dinosaurs roaming the open meadows and charging down snowy slopes. So it’s no wonder that Native Americans who ingested this plant would have developed religion. * Walking Castroville’s streets after school I got into fights but mostly watched other boys scrabbling on the asphalt. I went to Burger King for Whoppers. Me and my friends cussed. Antonio admonished me when I said, “damn,” while strutting a sidewalk alongside the church. He said, “Jaime”—pronounced Hi-May, which was what all the Mexicans called me—“you’re crazy, eh. Don’t cuss at the church.” He meant while at church, as in, within its vicinity. I said, “We’re not in church.” Once we’d crossed the street, Tony said, “Damn dude, you’re fuckin crazy!” * Blessed Father Fray Junípero Serra raised the Eucharistic goblet to his lips, and candlelight danced on the blood’s tiny waves. Incense clouded the church so completely that some of the Pame natives grew nauseous. So, too, felt Blessed Father Fray Junípero Serra later that night, as he bent over a ceramic bowl and vomited blood, not only the Lord’s, but his own, for poison had laced the sacred vessel into which he poured the sacrament. The physician tending to the sick prelate urged him to take the remedy he’d prepared. But Blessed Father Fray Junípero Serra refused, said that he would pray, for he had never taken any medicine in his life, and he never would. * The Chumash of El Valle de Los Osos called themselves the Stishni, separating themselves from Chumash of other regions, those varying tribes of the central California coast that spoke mutually unintelligible dialects of their Hokan language. This made learning their languages impossible for the Spanish friars, to say nothing of translating the Doctrina. Thus the priests baptized few natives, despite the help that the tribes offered the fledgling settlements in the form of meat and acorn meal, which the Spaniards found repugnant. Some from these cultures, feeling threatened by the newcomers, shot flaming arrows into the thatched roofs of the mission structures. And why wouldn’t they feel threatened when priests chastised them for performing, for example, their Coyote Dance, wherein a man donning a coyote-skin-and-skull costume dances while a singer sings his tale, which laments the human feces strewn imaginatively about the Earth? Coyote, meantime, tries to get an onlooker to lick his genitals, and finally engages in public sexual intercourse with a female tribe member or two, then ends the dance by defecating. Though the Franciscans called such forbidden acts devilry , the Chumash maintained their Datura cult religion, along with the enforced Christianity. For the Chumash, the Earth was made of two enormous snakes that caused earthquakes when they slithered past one another—a vast reptilian tectonics. In the 20th century, long after Blessed Father Fray Junípero Serra and his cohorts had died, when asked by an anthropologist about religious contradictions, conflating the Datura and Christian cults, a Chumash man replied, incredulous: “But these are two different religions.” * When Portolá ordered that if by March 19th, the feast day of St. Joseph, the San Antonio had not arrived in San Diego Bay to relieve them, the Sacred Expedition to Nueva California would be abandoned, Blessed Father Fray Junípero Serra prayed a novena for San José’s intercession. And lo, a lookout sighted the San Antonio ’s sails—what seemed to the priest a miracle—that very Saint’s feast day. Europeans would stay in California, and Blessed Father Fray Junípero Serra would continue to reap a great harvest of souls for the Lord. By the end of mission secularization in 1836—sixty-six years after the San Antonio rescued the Spaniards—Native American populations in California had declined by seventy-three percent. * When Peter the Aleut would not renounce his Eastern Orthodox faith the padre of San Francisco had a toe severed from each foot with each refusal, totaling ten. The native Ohlones employed in this gruesome task—their obsidian chiseled knives tearing through skin and grinding bone—continued as per their orders, and cut off also each of Peter’s fingers (equals a total of twenty refusals). They quartered the martyr, spilled his bowels, as if from bear attack, attack by a bear in the shape of a Catholic. * Blessed Father Fray Junípero Serra absolutely believed that the slow rate of conversion for the native people was due to the influence of the Devil, who had been outraged by the coming of the Catholics to California, this region that he had long held in his dominion. * In his reception speech for the Nobel Prize for Literature, John Steinbeck said, “Man himself has become our greatest hazard and our only hope. So that today, St. John the Apostle may well be paraphrased: In the end is the Word, and the Word is Man—and the Word is with Men.” * In 1602, when Sebastián Vizcaíno and his friars sang mass on Catalina Island, as many as a hundred Pimungans witnessed the rite, asking by signs what it was about. According to Vizcaíno’s records, the Californians marveled not a little at the idea of Heaven and at the image of Jesus crucified. * Vizcaíno was brought to a prairie on Santa Catalina Island where the Pimungans worshipped their sun god. Upon the prairie they had placed an icon, a headless figure with horns protruding from the body, a figure that Vizcaíno predictably described as a demon. The Pimungans urged Vizcaíno not to approach the image of their deity, but he ignored them. He placed his crucifix against the wooden figurine and prayed the Our Father. Vizcaíno told the natives that his prayer was from Heaven, and that their god was the Devil. Vizcaíno held out his crucifix, encouraging the Pimungans to touch it and receive Jesus. He pointed at the sky and indicated Heaven. The Pimungans worshipped a sun deity, so they were impressed with this white man and his description of his god, for their gods seemed to be one and the same. It’s no wonder then that Vizcaíno’s diary reports the natives being pleased with this exchange. “Surely,” the diary says, “they will be converted to our Holy Faith.” * The Miwok women wailed and scratched at their faces when their men consorted with Sir Francis Drake and the other Englishmen who had landed on California’s coast in the summer of 1579. “The blood streaming downe along their brests, besides despoiling the upper parts of their bodies of those single coverings . . .they would with furie cast themselves upon the ground . . . on hard stones, knobby hillocks, stocks of wood, and pricking bushes.” Drake and his men fell themselves to their knees in prayer, their eyes Heavenward, so that the natives might see they prayed to God and they too might worship God then their eyes that had been so blinded by the deceiver might be opened. * Father Fray Antonio de la Ascención—Carmelite friar in Vizcaíno’s party—writes that the Indians of California can “easily and with very little labor be taught our Holy Catholic faith, and that they would receive it well and lovingly.” He calls for two hundred older and honorable soldiers to ensure brotherhood during the conquest, so that peace and love—the best tools to pacify pagans—should reign. The religious, the friar says, should likewise be wise and loving to easily quell animosities between Spaniards and the heathen, and therefore avoid war. The Spaniards should bring with them trinkets—beads, mirrors, knives—to distribute amongst the gentiles, so that they might come to love the Christians, and see “that they are coming to their lands to give them that of which they bring, and not to take away the Indians’ possessions, and may understand that they are seeking the good of their souls.” No women are to accompany the conquest, says Father Fray Antonio, “to avoid offenses to God.” * In 1955 Wallace Stevens admitted himself to St. Francis Hospital in Hartford, Connecticut. There, it’s rumored he converted to Catholicism before dying of stomach cancer, exclaiming to his priest after the baptism, “Now I am in the fold.” Stevens’s late-career poems seem less cynical, more in awe of being and death (read “Metaphor as Degeneration” from The Auroras of Autumn ). He could have chosen from at least three secular hospitals in Hartford at the time. * I was reading Stevens’s Collected Poems when I joined eHarmony and listed that as my “currently reading” book among the “more than twelve” books a year that I would read. I fell in love with my wife when she said, “Are you sending your work out to literary journals?” Prior to this, the first girl I talked to on the phone, when I explained my doctoral exams, said, “So, you’re like, reading Stephen King and stuff?” When I said not exactly she responded defensively: “He must be doing something right, since he makes all that money.” * Mom walked me, my brother, and sister, through the Stations of the Cross. We did this on Ash Wednesdays, or whenever she thought we needed extra God after church. It might’ve happened before church, though that’s unlikely because we were always late. Anyway, it’s easiest to walk the Stations of the Cross when there’s no one else around. To walk the actual Stations means one goes to Jerusalem and walks the Via Dolorosa to the Church of the Holy Sepulchre. So the Stations elsewhere—usually paintings, or low-relief sculptures upon church walls—serve as a kind of virtual Dolorosa. Mom held our hands and started from the rear of Our Lady of Refuge: the First Station. Mom said we should say a prayer at each Station and to think of all the pain Jesus went through so that we could go to Heaven. It was hard to keep thinking about that one thing for so long. My mind went to that Saturday’s little league game, to the donut and chocolate milk (our after-church reward from Castroville Bakery), and as I grew older I thought about girls. When you’re thirteen you can’t not think about the girl’s butt in the pew in front of yours as she kneels and stands to pray throughout mass. * It grew increasingly juvenile to lie awake at night daring myself to utter a simple sentence. Even if I said I didn’t believe in God, wouldn’t He know the truth? He was omniscient, like a narrator. Even the idea of Him as a him ceased making sense. Not only did this come with a budding realization of my paternalistic culture, but due to the simple question of why? If God was everything, everywhere, all knowing, then why would he be a man? There’s that question: If God is a man then God must have a penis, and if so, what for? * The Catholic Church incorporates some modern scientific research into its dogma concerning the formation of the Universe, Solar System, and Earth, as well as evolution. According to Catholic doctrine, in approximately the fifth millennia BCE, humans began to worship the one true God. Those humans were Adam and Eve, though the Church says humans had been around for thousands of years prior to Adam and Eve. The Church claims to be infallible. Every time the Church changes its doctrine it remains infallible. * One Catholic writer, Tom Meagher, writes that “Modernism[—]the idea that we come to our beliefs individually through emotional or personal experiences[—]has crept into our Catholic schools.” * Catholics believe that evil spirits, given power through Original Sin, can imbue ordinary inanimate objects of everyday use. Thus, such objects should be blessed in order to induce in them the desire to serve the good. Such objects are not limited to, but include, “new ships and boats, railways and trains, bridges, fountains, wells, cornmills, limekilns, smelting furnaces, telegrams, steam engines, and machines for providing electricity.” * In The Sound of Music Julie Andrews and Christopher Plummer sing together: “Nothing comes from nothing, nothing ever could...” * To explain competing theories on the very early universe, and pre-verse would be another book. What was the inflaton? Did (mem)branes collide, initiating the Big Bang, as opposed to Lemaître’s primordial atom, a singularity? Without a unified theory there’s gravity hanging out there, fucking everything up. We cannot make sense of the mechanics of the Planck Epoch—0-10-34 seconds into the Universe’s creation—named for Max Planck, who stumbled into the discovery of quantum mechanics in the early twentieth century. * My students often ask if I believe in God, since I espouse evolution, the Big Bang, Science, reject a strictly biblical or creationist theory of the Universe. I tell them that yes, I believe in God, though not the God that they imagine one must believe in. * When questioned regarding the rumor that, before his death, founder of quantum mechanics Max Planck had converted to Catholicism, he replied that he did not believe “in a personal God, let alone a Christian God.” * Physicist and Catholic priest George Lemaître, who formulated the theory and wrote the 1946 book The Primeval Atom Hypothesis , was made a household name by then-detractor Fred Hoyle, who pejoratively referred to the idea as a “Big Bang.” * Suicide is a mortal sin. To end one’s own life one must have despair, which is to lose hope, which is to lose faith, and to disbelieve in God. * Archaeology has uncovered graffiti in all of California’s missions—Indian pictographs inscribed into the adobe, covered with layers of whitewash. Native deities and depictions of cultural practices show that tribespeople never fully gave up their native traditions even after baptism and coming to the missions. There was something inside Native Californians that would never die. (shrink)

This essay examines some of the arguments in David Deutsch's book The Fabric of Reality , chief among them its case for the so-called many-universe interpretation of quantum mechanics (QM), presented as the only physically and logically consistent solution to the QM paradoxes of wave/particle dualism, remote simultaneous interaction, the observer-induced 'collapse of the wave-packet', etc. The hypothesis assumes that all possible outcomes are realized in every such momentary 'collapse', since the observer splits off into so many parallel, coexisting, (...) but epistemically non-interaccessible 'worlds' whose subsequent branchings constitute the lifeline-or experiential world-series- for each of those proliferating centres of consciousness. Although Deutsch concedes that his 'multiverse' theory is counter-intuitive, he none the less takes it to be borne out beyond question by the sheer observational/predictive success of QM and the conceptual dilemmas that supposedly arise with alternative (single-universe) accounts. Moreover, he claims the theory resolves a range of longstanding philosophical problems, notably those of mind/body dualism, the various traditional paradoxes of time, and the freewill/determinism issue. The essay suggests on the contrary, that Deutsch unwittingly transposes into the framework of presentday quantum debate speculative themes from the history of rationalist metaphysics, often with bizarre or philosophically dubious results, and that he rules out at least one promising rival account, namely Bohm's 'hidden variables' theory. It goes on to consider reasons for resistance to that theory among proponents of the 'orthodox' (Copenhagen) doctrine, and for the strong anti-realist, at times even irrationalist bias that has characterized much of this discussion since Bohr's debates with Einstein about quantum non-locality, observer-intervention, and the limits of precise measurement. Finally, the contrast is pointed out between Deutsch's ontologically extravagant use of the many-worlds hypothesis (akin to certain ideas advanced by speculative metaphysicians from Leibniz down) and those realist modes of counterfactual reasoning- e.g. in Kripke and the early Putnam- which deploy similar arguments to very different causal-explanatory ends.

Unlike our basic theories of space and time, quantum mechanics is not a locally causal theory. This well known fact was brought forth by Einstein, Podolsky, and Rosen in 1935. Today it is widely believed that any hopes of restoring local causality within a realistic theory have been undermined by Bell's theorem and its supporting experiments. By contrast, we provide a strictly local, deterministic, and realistic explanation for the correlations observed in two such supporting experiments performed at Orsay and (...) Innsbruck. To this end, a pair of local variables is constructed to simulate detections of photon polarizations at various angles, chosen freely by Alice and Bob. These generate purely random outcomes: A = +/-1 and B = +/-1. When these outcomes are compared, however, the correlation between them turn out to be exactly equal to -cos2, with the corresponding CHSH inequality violated for the polarization angles alpha, alpha', beta, and beta' in precisely the manner predicted by quantum mechanics. The key ingredient in our explanation is the topology of 3-sphere, which remains closed under multiplication, thus preserving the locality condition of Bell. (shrink)

Quantum probability (QP) theory provides an alternative account of empirical phenomena in decision making that classical probability (CP) theory cannot explain. Cognitive architectures combine probabilistic mechanisms with symbolic knowledge-based representations (e.g., heuristics) to address effects that motivate QP. They provide simple and natural explanations of these phenomena based on general cognitive processes such as memory retrieval, similarity-based partial matching, and associative learning.

Radical ontic structural realism (ROSR) asserts an ontological commitment to ‘free-standing’ physical structures understood solely in terms of fundamental relations, without any recourse to relata that stand in these relations. Bain ([2013], pp.1621–35) has recently defended ROSR against the common charge of incoherence by arguing that a reformulation of fundamental physical theories in category-theoretic terms (rather than the usual set-theoretic ones) offers a coherent and precise articulation of the commitments accepted by ROSR. In this essay, we argue that category theory (...) does not offer a more hospitable environment to ROSR than set theory. We also show that the application of category-theoretic tools to topological quantum field theory and to algebraic generalizations of general relativity do not warrant the claim that these theories describe ‘object-free’ structures. We conclude that category theory offers little if any comfort to ROSR. 1 Introduction: Ridding Structures of Objects2 The Set-theoretic Peril for Radical Ontic Structural Realism3 Bain’s Categorial Strategy to Save Radical Ontic Structural Realism4 Throwing out the Relations with the Relata5 Categorial and Set-theoretical Structures6 Radical Suggestions from Topological Quantum Field Theory?7 Sheaves of Einstein Algebras as Radical Structures?8 Conclusions.

This paper examines two objections by Colin McGinn to panexperientialist metaphysics as a solution to the mind-body problem. It begins by briefly stating how the `ontological problem' of the mind-body relationship is central to the philosophy of mind, summarizes the difficulties with dualism and materialism, and outlines the main tenets of panexperientialism. Panexperientialists, such as David Ray Griffin, claim that theirs is one approach to solving the mind-body problem which does not get stuck in accounting for interaction nor in (...) the difficulties with emergentism and epiphenomenalism . McGinn attacks panexperientialism on two fronts: the Whiteheadian distinction between `consciousness' and `experience' and the notion of consciousness emerging from `non-conscious experience'; and the implicit `absurdities' inherent in the notion of experience and self-agency in the fundamental particles of physics. Griffin's defence fails to satisfactorily address challenge ; though a model is presented by the author which may offer panexperientialism a way out. McGinn's challenge is an attempted reductio which Griffin rejects: that panexperientialism contradicts the evidence of modern quantum- relativistic physics. The author's analysis of the opposing positions shows that both philosophers are arguing from incompatible `geometries of discourse' and radically inconsistent metaphysical assumptions. The paper concludes that a resolution of both the mind-body problem in general, and of the McGinn-Griffin dispute in particular, needs to involve an epistemological shift to include extra-rational ways of knowing.

This essay considers and evaluates recent results and arguments from classical chaotic systems theory and non-relativistic quantum mechanics that pertain to the question of whether our world is deterministic or indeterministic. While the classical results are inconclusive, quantum mechanics is often assumed to establish indeterminism insofar as the measurement process involves an ineliminable stochastic element, even though the dynamics between two measurements is considered fully deterministic. While this latter claim concerning the Schrödinger evolution must be qualified, the former (...) fully depends on a resolution of the measurement problem. Two alleged proofs that nature is indeterministic, relying, in turn, on Gleason's theorem and Conway and Kochen's recent 'free will theorem', are shown to be wanting qua proofs of indeterminism. We are thus left with the conclusion that the determinism question remains open. (shrink)

Two widely different conceptions of electromagnetic radiation were compared by Einstein in his 1916 papers, namely, the classically diffuse form and the fully directional form. The emission process of each kind of radiation is examined hereafter from a relativistic point of view. The necessary covariance of any physical description, further specifying the original directional property, points to a strictly quantized form of radiation as the only one consistent with relativity, thus showing a deep relationship between this latter and (...) class='Hi'>quantum theory.

This article presents an edited excerpt from a hitherto unknown fragmentary treatise by Rush Rhees. In the treatise, Rhees gives his account of the problem of continuity that he had started elaborating before he became acquainted with Wittgenstein. The excerpt, which contains Rhees' original distinction between outer and inner surfaces of bodies, builds on Brentano's theory of the continuum and his doctrine of plerosis. This treatment of continuity sheds light on Rhees' early philosophical development and confirms that even (...) though he and Wittgenstein discussed the problem of continuity, Rhees' own approach remained distinct from that of Wittgenstein.

In dialogue with Jürgen Habermas's communicative ethics, Covenant and Communication constructively explores a covenantal-communicative model of Christian ethics. Author Hak Joon Lee analyzes themes of freedom, equality, and reciprocity in Habermas's theory of communication from the perspective of the Reformed Christian doctrines of covenant and the Trinity.

The law of the future faces fundamental challenges that it cannot overcome by means of ‘tried and trusted’ dogmatics alone. Nor can it, from a methodological standpoint, take refuge in a purportedly apolitical hermeneutics or a one-sided application of empirical methods. Its responsibilities are not exhausted in mere steering, innovation or stimulating operations, but also encompass critical-emancipatory functions. Methodological reflection and legal critique - understood as social theory in the ‘interior’ of law - enable legal doctrine to meet the (...) particular demands that arise from the simultaneous affiliation of jurisprudence to the systems of law and science. The future development of legal studies thus requires a foundational research approach that preserves the interdisciplinary connection to neighbouring disciplines in the humanities and social sciences, and provides impetus for enlightened self-critique and self-reflection. Only in this way - through the emergence of jurisprudence from its self-incurred ignorance regarding its social function - might legal practice assert itself in everyday legal life and confront the injustices of the legal world with its own thinking. Such critical legal thinking demands more than just the perpetuation of traditions based on the history of ideas. Nor can it be satisfied through the mere cultivation of empirical approaches to reality. It must aim to develop and unfold a normative concept of law, and write this forward into the future. It derives its essential reflective potential from social-theoretical modelling and methodological development. In the process, the reciprocal confrontation and translation of rival theoretical models opens new learning possibilities not to solve legal conflicts, but to treat them more judiciously. Here, it is above all the foundational legal subjects that, through their discrete approaches and perspectives, open diverse and flexible entryways to the potentialities and actualities of law and, particularly in light of new cases, ensure the necessary variance of options for perception and action. The future of law resides in experimental testing and innovative discovery, in the creative quest for alternative possibilities and possible realities, in the critical and constructive struggle for the law of the future - as the ecological law of future life in the next bio-digital society.
