I outline some of my work and results on my matter-gravity entanglement hypothesis, according to which the entropy of a closed quantum gravitational system is equal to the system’s matter-gravity entanglement entropy. The main arguments presented are: that this hypothesis is capable of resolving what I call the second-law puzzle, i.e. the puzzle as to how the entropy increase of a closed system can be reconciled with the asssumption of unitary time-evolution; that the black hole information loss puzzle may be (...) regarded as a special case of this second law puzzle and that therefore the same resolution applies to it; that the black hole thermal atmosphere puzzle can be resolved by adopting a radically different-from-usual description of quantum black hole equilibrium states, according to which they are total pure states, entangled between matter and gravity in such a way that the partial states of matter and gravity are each approximately thermal equilibrium states ; that the Susskind–Horowitz–Polchinski string-theoretic understanding of black hole entropy as the logarithm of the degeneracy of a long string cannot be quite correct but should be replaced by a modified understanding according to which it is the entanglement entropy between a long string and its stringy atmosphere, when in a total pure equilibrium state in a suitable box, which ) goes over, at strong-coupling, to a black hole in equilibrium with its thermal atmosphere. The modified understanding in is based on a general result, which I also describe, which concerns the likely state of a quantum system when it is weakly coupled to an energy-bath and the total state is a random pure state with a given energy. This result generalizes Goldstein et al.’s ‘canonical typicality’ result to systems which are not necessarily small. (shrink)

We provide a suitable theoretical foundation for the notion of the quantum coherent state which describes the electrostatic field due to a static external macroscopic charge distribution introduced by the author in 1998 and use it to rederive the formulae obtained in 1998 for the inner product of a pair of such states. (We also correct an incorrect factor of 4π\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$4\pi$$\end{document} in some of those formulae.) Contrary to what one might expect, (...) this inner product is usually non-zero whenever the total charges of the two charge distributions are equal, even if the charge distributions themselves are different. We actually display two different frameworks that lead to the same inner-product formulae, in the second of which Gauss’s law only holds in expectation value. We propose an experiment capable of ruling out the latter framework. We then address the problem of finding a product picture for QED—i.e. a reformulation in which it has a total Hamiltonian, arising as a sum of a free electromagnetic Hamiltonian, a free charged-matter Hamiltonian and an interaction term, acting on a Hilbert space which is a subspace (the physical subspace) of the full tensor product of a charged-matter Hilbert space and an electromagnetic-field Hilbert space. (The traditional Coulomb gauge formulation of QED isn’t a product picture in this sense because, in it, the longitudinal part of the electric field is a function of the charged matter operators.) Motivated by the first framework for our coherent-state construction, we find such a product picture and exhibit its equivalence with Coulomb gauge QED both for a charged Dirac field and also for a system of non-relativistic charged balls. For each of these systems, in all states in the physical subspace (including the vacuum in the case of the Dirac field) the charged matter is entangled with longitudinal photons and Gauss’s law holds as an operator equation; albeit the electric field operator (and therefore also the full Hamiltonian) while self-adjoint on the physical subspace, fails to be self-adjoint on the full tensor-product Hilbert space. The inner products of our electrostatic coherent states and the product picture for QED are relevant as analogues to quantities that play a rôle in the author’s matter-gravity entanglement hypothesis. Also, the product picture provides a temporal gauge quantization of QED which appears to be free from the difficulties which plagued previous approaches to temporal-gauge quantization. (shrink)

Ludwig Wittgenstein was a brilliant, intense, complex man, and this novel, a work of historical fiction but based on fact, explores his early thinking, which led him to publish one of the most important works of logic ever written. The story is told by David Pinsent, a student in mathematics who meets Wittgenstein at Trinity College in Cambridge, England, just before World War I. Despite Wittgenstein’s odd mannerisms and difficult personality, David is attracted to him, recognizing his genius immediately and (...) forming a friendship that is as volatile as it is rewarding. Wittgenstein, under the tutelage of the eminent mathematician and philosopher Bernard Russell, has developed a picture theory of meaning to explain human language through the lens of logic, and he is tormented by the idea that he will die before he is able to put it into book form and present it to the world. -/- Both David and Ludwig are welcomed into the elite intellectual circles at Cambridge, which consist of some of the most notable philosophers, mathematicians, and logicians of the day, including not just Russell but also men like John Maynard Keynes and G.E. Moore, as well as the famous Bloomsbury Set. However, David is troubled by the mysteries that surround Wittgenstein. Ludwig, he learns, has developed an innovative propeller that can be used on a flying bomber, and David finds himself caught up in international intrigue as both England and Germany vie for the design to give them an advantage in the impending war. -/- But David and Ludwig have become both emotionally and physically intimate, and as war looms, David is forced to confront the role that their forbidden relationship plays in the escalating risks to Wittgenstein’s safety. Their story is one of tragedy and inspiration, and it aptly illustrates the deeply human core of philosophical ideas. This novel illuminates and clarifies the complex philosophical, linguistic, and mathematical issues that engaged some of the best thinkers of the early twentieth century. -/- There is an accompanying guidebook for this novel.

Yet, the central conviction that informs this volume is that phenomenology provides extraordinary insights into many of the issues that are directly addressed ...

In this paper I reflect upon my personal experience of chronic progressive multiple sclerosis in order to provide a phenomenological account of the human experience of disability. In particular, I argue that the phenomenological notion of lived body provides important insights into the profound disruptions of space and time that are an integral element of changed physical capacities such as loss of mobility. In addition, phenomenology discloses the emotional dimension of physical disorder. The lived body disruption engendered by loss of (...) mobility includes a change in the character of surrounding space, an alteration in one's taken-for-granted awareness of objects, the disruption of corporeal identity, a disturbance in one's relations with others, and a change in the character of temporal experience. The loss of upright posture is of particular significance since it not only concretely diminishes autonomy but affects the way one is treated by others. Such a change in posture is, therefore, particularly disruptive in the social world of everyday life. An understanding of the lived body disruption engendered by disability has important applications for the clinical context in devising effective therapies, as well as for the social arena in determining how best to resolve the various challenges posed by chronic disabling disorders.

This essay argues that philosophical phenomenology can provide important insights into the patient-physician relationship. In particular, it is noted that the physician and patient encounter the experience of illness from within the context of different "worlds", each "world" providing a horizon of meaning. Such phenomenological notions as focusing, habits of mind, finite provinces of meaning, and relevance are shown to be central to the way these "worlds" are constituted. An eidetic interpretation of illness is proposed. Such an interpretation discloses certain (...) essential characteristics that pertain to the experience of illness, per se , regardless of its manifestation in terms of a particular disease state. It is suggested that, if a shared world of meaning is to be constituted between physician and patient, the eidetic characteristics of illness must be recognized by the physician.

This paper suggests that the paradigm of lived body (as it is developed in the works of Merleau-Ponty, Sartre and Zaner) provides important insights into the experience of illness. In particular it is noted that, as embodied persons, we experience illness primarily as a disruption of lived body rather than as a dysfunction of biological body. An account is given of the manner in which such fundamental features of embodiment as bodily intentionality, primary meaning, contextural organization, body image, gestural display, (...) lived spatiality and temporality, are disrupted in illness causing a concurrent disorganization of the patient's self and world. The paradigm of lived body has important applications for medical practice. It provides a fuller account of illness than does the prevailing reductionist Cartesian paradigm of body, more directly addresses the existential predicament of illness, and orients the clinical focus around the personhood of the patient.

In this paper I briefly summarize Pellegrino’s phenomenological analysis of the ethics of the physician–patient relationship. In delineating the essential elements of the healing relationship, Pellegrino demonstrates the necessity for health care professionals to understand the patient’s lived experience of illness. In considering the phenomenon of illness, I identify certain essential characteristics of illness-as-lived that provide a basis for developing a rigorous understanding of the patient’s experience. I note recent developments in the systematic delivery of health care that make it (...) difficult for health care professionals to realize Pellegrino’s ethical model of the role of healer. Such developments limit both the physician’s freedom to act on behalf of the patient without the constraint of third parties and the physician’s freedom to act in light of his or her own ethical or religious convictions. Given these difficulties, I note MacIntyre’s call for the development of moral communities, as an alternative to the prevailing culture, and share a first-hand example illustrating how intentional Christian community provides an alternative nurturing context that permits the full development of the healing relationship.

This essay argues that, while much has been gained by medicine's focus on the spatial aspects of disease in light of developments in modern pathology, too little attention has been given to the temporal experience of illness at the subjective level of the patient. In particular, it is noted that there is a radical distinction between subjective and objective time. Whereas the patient experiences his immediate illness in terms of the ongoing flux of subjective time, the physician conceptualizes the illness (...) as a disease state according to the measurements of objective time. A greater understanding of this disparity in temporal experiencing provides insights into the lived experience of illness and can preclude difficulties in communication between physician and patient.

Book reviewed in this article: The Meaning of Illness. By S. Kay Toombs.

Time is analyzed as being those processes by which a system notes the processes which comprise its own existence. The directionality of time is given by the concepts, past, present, and future. To understand the meaning of these concepts, a set of experiments was carried out with four male subjects in which areas of time were expanded or ablated by means of post-hypnotic suggestions. These operations were carried out singly or in combination. The data suggest that the present is primarily (...) associated with stimulus input, the past with the criteria for defining that input as well as the development of response inhibitions and the future with the directionality of that input. Marked personality changes which range from the occurence of catatonic-like states to obsessive types of reaction and manic-like reactions are associated with different combinations of time alterations. Some of the changes are in accord with the serialist position on time of J. W. Dunne. The concept of death is very important both with regard to one’s view of time and how one lives. While it is important to live in the present, the present has no meaning without at least a past or a future. Implications of these findings for psychopathology in general and schizophrenia in particular are considered. (shrink)

In this essay I discuss Edith Stein's analysis of empathy and note its application in the field of clinical medicine. In identifying empathy as the basic mode of cognition in which one grasps the experiences of others, Stein notes, 'I grasp the Other as a living body and not merely as a physical body'. The living body is given in terms of five distinctive characteristics - characteristics that disclose important facets of the illness experience. Empathy plays an important role in (...) clinical practice in aiding physicians to grasp the content of first-person reports of bodily disorder, and to comprehend the meaning of illness-as-lived. I suggest that an important task for medical education should be that of developing students' capacity for empathic understanding and I note several ways in which this task might be accomplished.

Later reprinted by Deborah Charles Publications (and not available from Amazon), this book expounds and comments on the application of Greimasian semiotics to a legal text, as found in the article by Greimas and Landowski in Greimas, Sémiotique et Sciences Sociales (1976), compares this with the semiotic presuppositions of Hart, Dworkin, MacCormick and Kelsen, and offers my own analysis of the implications of such semiotic analysis for legal theory, including some more recent radical non-positivist accounts.

In order to gain greater insight into the nature of corporate social responsibility (CSR) during a time of crisis, the study examines the commitment of firms to continue to engage in CSR activity despite financial pressures to divert their slack resources elsewhere. The setting of the study is CSR activity during the perhaps unprecedented global crisis associated with the COVID-19 pandemic. Based on a qualitative research method approach, both a variety of media sources and the relevant academic literature are reviewed (...) in order to identify examples of CSR activity related specifically to COVID-19. The examples are then categorized and situated according to Professor Archie Carroll’s well-known CSR Pyramid framework describing the economic, legal, ethical, and philanthropic domains of CSR. As such, this study is the first to extend the rich literature stream utilizing Carroll’s CSR Pyramid within the unique context of a global pandemic. (shrink)

This book reviews the classical schools of jurisprudence with particular reference to their linguistic presuppositions, and summarises an alternative account based on Paris school semiotics. Detailed ToC available from linked web page. NOT available from Amazon.

Originally written in 1990, this reviews largely late 20th century debates on the study of law as Logic, Discourse, or Experience; the Unity of the Legal System and the Problem of Reference; Semiotic Presuppositions of Traditional Jurisprudence (Austin, Hart, Kelsen, Dworkin, Legal Realisms); then turns to legal philosophies explicitly Employing Forms of Semiotics (Kalinowski, the Italian Analytical School, Rhetorical and Pragmatic Approaches, Sociological and Socio-Linguistic Approaches, Peircian Legal Semiotics, Greimasian Legal Semiotics and Aesthetic/Symbolic Approaches). A major section then offers (from (...) a largely Greimasian point of view) some hypotheses for legal semiotics on the Problem of Reference, Semantic and Pragmatic Levels, Semiotic Groups and “The Legal Culture”, Normativity and Justification, and finally considers the implications for particular legal phenomena: the “Legal System”, Legal Institutions, Legal Codes, Legal Rules, Rights, Courtroom Behaviour: Witness and Counsel, The Judge: Justification of Decisions on Law, and the Criminal Justice Process. A conclusion addresses the status of legal semiotics. (shrink)

The technology of undersea communications, from stranded-wire telegraph cables in the 1850s to fiber-optic cables at the end of the twentieth century, and its social, political, and economic impact. By the end of the twentieth century, fiber-optic technology had made possible a worldwide communications system of breathtaking speed and capacity. This amazing network is the latest evolution of communications technologies that began with undersea telegraph cables in the 1850s and continued with coaxial telephone cables a hundred years later. Communications under (...) the Seas traces the development of these technologies and assesses their social, economic, and political effects. If we cannot predict the ultimate consequences of today's wired world--its impact on economic markets, free expression, and war and peace--or the outcome of the conflict between wired and wireless technology, we can examine how similar issues have been dealt with in the past. The expert contributors to this volume do just that, discussing technical developments in undersea cables, management of the cables by private and public interests, and the impact on military and political activities. Chapters cover such topics as the daring group of nineteenth-century entrepreneurs who wove a network of copper wires around the world ; the opening of the telegraphic network to general public use; the government- and industry-forced merger of wireless and cable companies in Britain; and the impact of the cable network on diplomacy during the two world wars.

In this paper, I ask whether mishpat ivri (Jewish Law) is appropriately conceived as a “legal system”. I review Menachem Elon’s use of a “Sources” Theory of Law (based on Salmond) in his account of Mishpat Ivri; the status of religious law from the viewpoint of jurisprudence itself (Bentham, Austin and Kelsen); then the use of sources (and the approach to “dogmatic error”) by halakhic authorities in discussing the problems of the agunah (“chained wife”), which I suggest points to a (...) theory more radical than the “sources” theory of law, one more akin to the ultimate phase of the thought of Kelsen (the “non-logical” Kelsen) or indeed to some form of Legal Realism (with which that phase of Kelsen’s thought has indeed been compared)?

This article is partly an exercise in academic autobiography, seeking to make sense of the different ways in which I have applied semiotics to secular law on the one hand, Jewish law on the other. The very fact that it can be applied to both shows that its claims are methodological. But it also indicates a possible reformulation of the semiotic issues in philosophical terms: we may view the relationship between the semantic and pragmatic levels in terms of the relationship/balance (...) between certainty/truth (the semantic level) on the one hand and trust (the pragmatic level) on the other. What may distinguish the secular and religious systems is the manner in the issue of trust is be ideologically concealed. (shrink)

In considering Van Schooten’s study of the Eric O. case (s.1), I ask whether the different approaches taken by the two different “legal institutions”—the prosecuting authorities on the one hand, the courts on the other—are reflective of different images of warfare (a semantic difference) or of the different images each group holds of its own role (a pragmatic difference). If we consider these two “legal institutions” as distinct semiotic groups (s.2), is there an inevitable “communication deficit” between them (and the (...) public)? (shrink)

Review of Lenn Goodman's On Justice (1st 3d.).

After a section of Methodological Preliminaries, I consider Truth and Argumentation in the Jewish Legal Tradition, under the following subheadings: Truth in Judaism, Truth and Norms, Truth and Language, Truth and Logic, Truth and Argumentation. I thus use an external framework in order to pose questions to the Jewish legal tradition, and identify internal resources which may provide partial answers to these questions. But are these partial answers so peculiar, theological, culturally contingent as to lack any value in terms of (...) a potential contribution to these same issues as posed within Western jurisprudence? This may be doubted, given the West’s adoption or construction of the divine right of kings on the one hand and of holistic theories of interpretation on the other, derived from the Bible and later Jewish tradition, mediated and fortified through a Christianised Rome.

This article reviews the opportunities for legal semiotics to contribute to legal philosophy, legal sociology, the reading of legal texts and the analysis of legal language (with bibliography) and surveys the institutional development of legal semiotics.

Despite the efforts of some modern Jewish law scholars, it is difficult to apply models of secular jurisprudence (whether positivist or Dworkinian) to the Jewish legal system. Internal analysis suggests that the “secondary rules” of the system are far too fragile. Rather, the system appears to privilege trust over objectively determinable truth. (But perhaps trust is a concept to which greater attention should be paid also in secular jurisprudence, as a legal realism informed by semiotics might maintain.) The practical implications (...) of this difference are here illustrated both from research on reform of Jewish marriage law and recent developments in the area of law and religion, in the wake of Archbishop Rowan Williams’ advocacy in 2008 of a model of “transformative accommodation”.
