The phase space realizations of quantum groups are discussed using *-products. We show that on phase space, quantum groups appear necessarily as two-parameter deformation structures, one parameter (v) being concerned with the quantization in phase space, the other (η) expressing the quantum groups as “deformation” of their Lie counterparts. Introducing a strong invariance condition, we show the uniqueness of the η-deformation. This suggests that the strong invariance condition is a possible origin of the quantum groups.

The Mesillas Yesharim / Path of the Just was the masterpiece of Rabbi Moshe Chaim Luzzatto, the great mystic, philosopher, sage, and saint. For centuries, this classic text for better living has been every man's primer for ideal life. Wherever there were Jews there was a well-thumbed Mesillas Yesharim. In this book, Rabbi Twerski applies the text and themes of Mesillas Yesharim to the everyday challenges of the 90s. He shows us how we can succeed in the quest for a (...) better life and in bettering ourselves. (shrink)

We consider quantum deformations of the real symplectic (or anti-De Sitter) algebra sp(4), ℝ ≅ spin(3, 2) and of its singleton and (4-dimensional) zero-mass representations. For q a root of −1, these representations admit finite-dimensional unitary subrepresentations. It is pointed out that Uq (sp(4, ℝ)), unlike Uq (su(2, 2)), contains Uq (sl 2 ) as a quantum subalgebra.

In this volume, the third in his classic series on art theory, Moshe Barasch traces the hidden patterns and interlocking themes in the study of art, from impressionism to abstract art. Barasch details the immense social changes in the creation, presentation, and reception of art which have set the history of art theory on a vertiginous new course: the decreased relevance of workshops and art schools; the replacement of the treatise by the critical review; and the emerging interrelationship between scientific (...) inquiry and artistic theory. The consequent changes in the ways in which critics as well as artists conceptualized paintings and sculptures were radical, marked by an obsession with intense sensory experiences, psychological reflection on the effects of art, and an attraction to the exotic and alien--making for the most exciting and fertile period in the history of art criticism.

The literature on conscientious objection in medicine presents two key problems that remain unresolved: Which conscientious objections in medicine are justified, if it is not feasible for individual medical practitioners to conclusively demonstrate the genuineness or reasonableness of their objections? How does one respect both medical practitioners’ claims of conscience and patients’ interests, without leaving practitioners complicit in perceived or actual wrongdoing? My aim in this paper is to offer a new framework for conscientious objections in medicine, which, by bringing (...) medical professionals’ conscientious objection into the public realm, solves the justification and complicity problems. In particular, I will argue that: an “Uber Conscientious Objection in Medicine Committee” —which includes representatives from the medical community and from other professions, as well as from various religions and from the patient population—should assess various well-known conscientious objections in medicine in terms of public reason and decide which conscientious objections should be permitted, without hearing out individual conscientious objectors; medical practitioners should advertise their conscientious objections, ahead of time, in an online database that would be easily accessible to the public, without being required, in most cases, to refer patients to non-objecting practitioners.

I offer a novel two-stage reconstruction of Hume’s general-point-of-view account, modeled in part on his qualified-judges account in ‘Of the Standard of Taste.’ In particular, I argue that the general point of view needs to be jointly constructed by spectators who have sympathized with (at least some of) the agents in (at least some of) the actor’s circles of influence. The upshot of the account is two-fold. First, Hume’s later thought developed in such a way that it can rectify the (...) problems inherent in his Treatise account of the general point of view. Second, the proposed account provides the grounds for an adequate and well-motivated modest ideal observer theory of the standard of virtue. (shrink)

The consequent changes in the ways in which critics as well as artists conceptualized paintings and sculptures were radical, marked by an obsession with intense, immediate sensory experiences, psychological reflection on the effects of art, and a magnetic pull to the exotic and alien, making for the most exciting and fertile period in the history of art criticism.

This book describes Carmeli's cosmological general and special relativity theory, along with Einstein's general and special relativity. These theories are discussed in the context of Moshe Carmeli's original research, in which velocity is introduced as an additional independent dimension. Four- and five-dimensional spaces are considered, and the five-dimensional braneworld theory is presented. The Tully-Fisher law is obtained directly from the theory, and thus it is found that there is no necessity to assume the existence of dark matter in the halo (...) of galaxies, nor in galaxy clusters.The book gives the derivation of the Lorentz transformation, which is used in both Einstein's special relativity and Carmeli's cosmological special relativity theory. The text also provides the mathematical theory of curved space?time geometry, which is necessary to describe both Einstein's general relativity and Carmeli's cosmological general relativity. A comparison between the dynamical and kinematic aspects of the expansion of the universe is made. Comparison is also made between the Friedmann-Robertson-Walker theory and the Carmeli theory. And neither is it necessary to assume the existence of dark matter to correctly describe the expansion of the cosmos. (shrink)

Vardi, M.Y., Verification of concurrent programs: the automata-theoretic framework, Annals of Pure and Applied Logic 51 79–98. We present an automata-theoretic framework to the verification of concurrent and nondeterministic programs. The basic idea is that to verify that a program P is correct one writes a program A that receives the computation of P as input and diverges only on incorrect computations of P. Now P is correct if and only if a program PA, obtained by combining P and A, (...) terminates. We formalize this idea in a framework of ω-automata with a recursive set of states. This unifies previous works on verification of fair termination and verification of temporal properties. (shrink)

Answers to the questions of what justifies conscientious objection in medicine in general and which specific objections should be respected have proven to be elusive. In this paper, I develop a new framework for conscientious objection in medicine that is based on the idea that conscience can express true moral claims. I draw on one of the historical roots, found in Adam Smith’s impartial spectator account, of the idea that an agent’s conscience can determine the correct moral norms, even if (...) the agent’s society has endorsed different norms. In particular, I argue that when a medical professional is reasoning from the standpoint of an impartial spectator, his or her claims of conscience are true, or at least approximate moral truth to the greatest degree possible for creatures like us, and should thus be respected. In addition to providing a justification for conscientious objection in medicine by appealing to the potential truth of the objection, the account advances the debate regarding the integrity and toleration justifications for conscientious objection, since the standard of the impartial spectator specifies the boundaries of legitimate appeals to moral integrity and toleration. The impartial spectator also provides a standpoint of shared deliberation and public reasons, from which a conscientious objector can make their case in terms that other people who adopt this standpoint can and should accept, thus offering a standard fitting to liberal democracies.

John Rawls raises three challenges – to which one can add a fourth challenge – to an impartial spectator account: (a) the impartial spectator is a utility-maximizing device that does not take seriously the distinction between persons; (b) the account does not guarantee that the principles of justice will be derived from it; (c) the notion of impartiality in the account is the wrong one, since it does not define impartiality from the standpoint of the litigants themselves; (d) the account (...) would offer a comprehensive, rather than a political, form of liberalism. The narrow aim of the article is to demonstrate that Adam Smith's impartial spectator account can rise to Rawls's challenges. The broader aim is to demonstrate that the impartial spectator account offers the basis for a novel and alternative framework for developing principles of justice, and does so in the context of a political form of liberalism.

Multinational corporations' international staffing policies have been evaluated in terms of cost and efficiency arguments. Research has not addressed, however, the ethical impact of these policies on diverse stakeholder groups. This paper presents a conceptual framework by which ethnocentric, polycentric and geocentric staffing policies are theoretically linked to underlying decision-making modes of instrumentality, bounded rationality and economic rationality, respectively. It goes on to describe the ethical rationales associated with each policy type, namely, distributive justice, moral rights of man, and utilitarianism. (...) An investigation of resulting ethical dilemmas affecting relevant MNC stakeholder groups is incorporated and offered as a tool for analyzing the true and full costs of trade-offs when choosing one policy over another. The paper concludes with a discussion of the implications of the conceptual framework for theory and practice and directions for future research. (shrink)

In the latter part of the fifteenth century, a Jewish translator, working together with a Slavic amanuensis, translated into the East Slavic language of the Grand Duchy of Lithuania three medieval Hebrew translations of Arabic philosophical texts: the Logical Terminology, a short work on logic attributed to Maimonides (but probably by a different medieval Jewish author); and two sections of the Muslim theologian Al-Ghazali's famous Intentions of the Philosophers. Highlighting the unexpected role played by Jewish translators as agents of cultural (...) transmission in the heady messianic atmosphere leading up to the year 1492, these texts drew the attention of the Orthodox Church authorities as being in the possession of the enlightened heretical sect known as the Judaizers, which had emerged in Novgorod and spread to Moscow. Reflecting three and even four layers of translation, Prof. Moshe Taube's new triple-language critical edition of the Logika of the Judaizers displays the Slavic texts alongside the Hebrew translations on which they are based and accompanies them with a modern English translation. In his comprehensive introduction and commentary, Taube surveys earlier scholarly efforts to identify the provenance and purport of the translations, discusses the linguistic and textological issues raised by these early Ruthenian texts, puts forward the likely dissimilar motivations of the Jewish translator and the Christians who commissioned the work, and reveals the translator's probable identity. The present publication, a long-awaited desideratum, will be of interest not only to historians of the Great Duchy of Lithuania and of the principality of Muscovy, but also to scholars of Jewish history and of the history of philosophy and science, as well as to linguists studying the history of the Belorussian, Ukrainian and Russian languages.

Two problems seem to plague Adam Smith’s account of sympathy and approbation in The Theory of Moral Sentiments (TMS). First, Smith’s account of sympathy at the beginning of TMS appears to be inconsistent with the account of sympathy at the end of TMS. In particular, it seems that Smith did not appreciate the distinction between ‘self-oriented sympathy’ and ‘other-oriented sympathy’, that is, between imagining being oneself in the actor’s situation and imagining being the actor in the actor’s situation. Second, Smith’s (...) account of approbation, according to which a sentiment of approval arises when there is recognition of concordance between the spectator’s sympathetic passion and the actor’s original passion, seems to face the following problem: since the spectator attains both his own sympathetic passion and the actor’s original passion by sympathizing with the actor, the sympathetic passion of the spectator and the original passion of the actor will necessarily be identical. Therefore, Smith’s account of approbation requires that the spectator utilize both self-oriented and other-oriented sympathy (‘the double-sympathy model of approbation’). I offer a novel developmental account of sympathy in TMS that renders Smith’s account of sympathy consistent and allows for the utilization of the double-sympathy model of approbation. (shrink)

A critical assessment of the second chapter of Samuel Fleischacker’s Being Me Being You, where Fleischacker makes use of Smith’s account of empathy to develop a distinctive Smithian conception of ‘humanity’.

Physicians frequently ask whether they should give patients what they want, usually when there are considerations pointing against doing so, such as medicine’s values and physicians’ obligations. It has been argued that the source of medicine’s values and physicians’ obligations lies in what has been dubbed “the internal morality of medicine”: medicine is a practice with an end and norms that are definitive of this practice and that determine what physicians ought to do qua physicians. In this paper, I defend (...) the claim that medicine requires a morality that is internal to its practice, while rejecting the prevalent characterization of this morality and offering an alternative one. My approach to the internal morality of medicine is constructivist in nature: the norms of medicine are constructed by medical professionals, other professionals, and patients, given medicine’s end of “benefitting patients in need of prima facie medical treatment and care.” I make the case that patients should be involved in the construction of medicine’s morality not only because they have knowledge that is relevant to the internal morality of medicine—namely, their own values and preferences—but also because medicine is an inherently relational enterprise: in medicine the relationship between physician and patient is a constitutive component of the craft itself. The framework I propose provides an authoritative morality for medicine, while allowing for the incorporation, into that very morality, of qualified deference to patient values. (shrink)

I build on Adam Smith’s account of the impartial spectator in The Theory of Moral Sentiments in order to offer a modest ideal observer theory of moral judgment that is adequate in the following sense: the account specifies the hypothetical conditions that guarantee the authoritativeness of an agent’s (or agents’) responses in constituting the standard in question, and, if an actual agent or an actual community of agents are not under those conditions, their responses are not authoritative in setting this (...) standard. However, in the account that I provide, the hypothetical conditions can themselves be constructed from the psychology and interactions of actual human beings. In other words, facts about the morally appropriate and inappropriate are determined from hypothetical conditions that––while agents in a given society might have yet to attain them––can be constructed from those agents’ shared experiences. Thus, the account offers both an attainable standard of moral judgment and a standard that can transcend the biases of the society which gave rise to it. I also defend the account against three challenges: (a) ideal observer theories do not offer the right kind of motivation to act on the verdicts of the ideal observer; (b) ideal observer theories cannot explain why the idealization in question is well-motivated and not objectionably ad hoc; (c) the standard used in ideal observer theories cannot be defended upon further reflection, because we would need a non-arbitrary, second-order standard to govern our reflection on the first-order standard of moral judgment.

"In the gorgeous and rugged terrain of Jewish thought, there is no higher mountain to climb than Maimonides, and no more slippery or exhilarating ascent. Halbertal has made it all the way to the top, and his survey of the whole of the Maimonidean landscape is trustworthy and masterful. This is the richest and most intellectually sophisticated book on Maimonides I have ever read."--Leon Wieseltier "In this learned and penetrating work, Halbertal offers us a Maimonides who draws on the dominant (...) Greco-Islamic thought of his time while creating a system of thought that is fully Jewish. He shows us how the early "Commentary on the Mishnah" links up with the "Mishneh Torah" and with the "Guide of the Perplexed," written at the end of his life, to form an unexpected and radical intellectual unity. Beautifully written, "Maimonides" brings out both Maimonides's intellectual success and the paradoxical critical approaches to him after his death."--David J. Wasserstein, Vanderbilt University "Insightful and learned. Halbertal is perhaps the leading philosopher of Jewish law today. His book on Maimonides, like his other writings, reflects wide erudition and is written clearly and sharply."--Warren Zev Harvey, professor emeritus, Hebrew University of Jerusalem "Displaying the marvelous depth and clarity that mark all his work, Halbertal explains in abundant detail the transformations that Maimonides sought to effect in the Jewish world. He provides incisive interpretations of both legal and philosophical writings, yet he is also a biographer, binding together Maimonides's life, self-perception, and intellectual agenda. This is an exceptionally rich book, one that offers fresh perspectives for experts and a highly accessible introduction for general readers."--David Shatz, Yeshiva University "An outstanding and thrilling portrait of Maimonides. Halbertal's analytic lucidity and psychological depth are singular, and his talents are abundantly apparent on every page. This is an extraordinary book."--Menachem Lorberbaum, Tel Aviv University.

This is an introduction to set theory and logic that starts completely from scratch. The text is accompanied by many methodological remarks and explanations.

My question in the chapter is this: could (and should) the role of the physician be construed as that of a friend to the patient? I begin by briefly discussing the “friendship model” of the physician-patient relationship—according to which physicians and patients could, and perhaps should, be friends—as well as its history and limitations. Given these limitations, I focus on the more one-sided idea that the physician could, and perhaps should, be a friend to the patient (a “physician-qua-friend model” of (...) the physician-patient relationship). I show that given recent developments in our understanding of the physician-patient relationship, this idea is far from asinine. I then make the case that the most plausible conception of the physician-qua-friend model incorporates the following components: (a) a common goal, that is, one that physician and patient share; (b) certain forms of equality between physician and patient; (c) an ideal of a caring physician. Finally, I show how the model can be instantiated in a certain type of physician-patient interaction, namely, in physician-assisted dying. (shrink)

During the twelfth and thirteenth centuries, great new trends of Jewish thought emerged whose widely varied representatives--Kabbalists, philosophers, and astrologers--each claimed that their particular understanding revealed the actual secret of the Torah. They presented their own readings in a coded fashion that has come to be regarded by many as the very essence of esotericism. Concealment and Revelation takes us on a fascinating journey to the depths of the esoteric imagination. Carefully tracing the rise of esotericism and its function in (...) medieval Jewish thought, Moshe Halbertal's richly detailed historical and cultural analysis gradually builds conceptual-philosophical force to culminate in a masterful phenomenological taxonomy of esotericism and its paradoxes. Among the questions addressed: What are the internal justifications that esoteric traditions provide for their own existence, especially in the Jewish world, in which the spread of knowledge was of great importance? How do esoteric teachings coexist with the revealed tradition, and what is the relationship between the various esoteric teachings that compete with that revealed tradition? Halbertal concludes that, through the medium of the concealed, Jewish thinkers integrated into the heart of the Jewish tradition diverse cultural influences such as Aristotelianism, Neoplatonism, and Hermeticisims. And the creation of an added concealed layer, unregulated and open-ended, became the source of the most daring and radical interpretations of the tradition. (shrink)
