In lieu of an abstract, here is a brief excerpt of the content:THE EUCHARISTIC THEOLOGIES OF LAUDA SION AND THOMAS AQUINAS'S SUMMA THEOLOGIAE THOMAS J. BELL Emory University Atlanta, Georgia MANY works associated with Thomas Aquinas stand both the Office and Mass for the Feast of Corpus Christi.1 The earliest witness to this association comes from two of Thomas's Dominican brothers and younger contemporaries, Tolomeo of Lucca and William of Tocco. Around 1317 Tolomeo wrote in (...) his Historia Ecclesiastica: " Thomas composed [the Corpus Christi Office] in full, including the lessons and all the parts to be recited by day or night; the Mass, too, and whatever has to be sung on the day." 2 William, in his Historia beati Thomae completed around 1320, lists the liturgy of Corpus Christi among Thomas's works and informs us that Thomas wrote the liturgy " at the request of Pope Urban [IV]." 3 It is known that on August 11, 1264, Urban, in the bull Transiturus, declared that the Feast of Corpus Christi was to be celebrated throughout Christendom according to a "new, Roman," liturgy.4 Thomas had returned from Paris to Italy, his 1 This does not mean that Thomas created the liturgy for the feast de nova. Rather it means that Thomas selected and combined older elements from the Scriptures, the Fathers, and existing liturgies, only venturing to write from scratch those hymns and prayers necessary for expressing the theological and devotional views central to the Feast of Corpus Christi. In other words, Thomas wrote or pieced together texts " proper " to the feast and united them with the " ordinary " texts of the Mass and Office. 2 James A. Weisheipl, Friar Thomas d'Aquino: His Life, Thought and Works (Washington, D.C., 1974), p. 177. a Ibid., pp. 132, 177. 4 Ibid., pp. 179, 183. For a partial translation of the bull Transiturus see also Darwell Stone, A History of the Doctrine of the Holy Eucharist (London, 1909), vol. 1, 344-46. This "new, Roman" liturgy promulgated by Urban IV was, indeed, a new 163 164 THOMAS J. BELL homeland, five years before the bull was published. Furthermore, by 1264 he had developed a "warm friendship" with Urban, whom we know to have commissioned Thomas to write several works between 1261 and 1265.5 These facts have led most scholars since the early fourteenth century to conclude that Urban's "new" liturgy was the work of Thomas.6 In recent years, however, Cyrille Lambot has questioned whether Thomas wrote or compiled the liturgy promulgated by Urban. He has noted that Reginald of Piperno, Thomas's amanuensis and companion from 1259 to 1274, did not include the liturgy for Corpus Christi in his list of Thomas's works. Moreover, the Dominican Order, like most Orders and dioceses, did not adopt Urban's liturgy for the Feast of Corpus Christi until 1317, when John XXII required its use throughout Western Christendom.7 If Thomas had written the liturgy, argues liturgy composed for the celebration of Corpus Christi. Around 1246 a certain John, a religious of Mont-Cornillon, had compiled a liturgy for the " Body of the Lord " that was in place throughout the diocese of Liege. Being so impressed by the solemnities of the Liege eucharistic celebration, Hugh of Saint-Cher, a Dominican and the cardinal legate of Germany, declared in 1252 that the feast of Corpus Christi was to be celebrated throughout the territory under his leadership. Jacques Pantaleon, the future Urban IV, knew the solemnities of Liege from his time as the city's archdeacon. It seems that upon his election as Pope, Urban was urged by many people to establish the Feast throughout Christendom. Eventually he did this with the publication of the bull Transiturus. For more details, see Weisheipl, Friar Thomas d'Aquino, pp. 178-79. 0 Weisheipl, Friar Thomas d'Aquino, p. 147. 6 The liturgy for the Feast of Corpus Christi that is associated with Thomas is not identical with the one currently used in both the Roman rite and Dominican rite. The modern texts for the Feast reflect the liturgical reforms that have occurred since Thomas's day. Notwithstanding these reforms, the Mass for the Feast (Cibavit eos), which includes Lauda Sion, has for the most part... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Journal of Aesthetic Education 38.2 (2004) 116-120 [Access article in PDF] Art History in the Age of Bellori: Scholarship and Cultural Politics in Seventeenth-Century Rome, edited by Janis Bell and Thomas Willette. Cambridge: Cambridge Universtiy Press, 2002, 396 pp. Giovan Pietro Bellori is a name familiar to all who have studied seventeenth-century Italian art. His magisterial book, The Lives of the Modern Painters, Sculptors, and Architects (...) (Le vite de' pittori, scultori, ed architetti moderni), published in Rome in 1672, continued in the grand tradition of artists' biographies established by Giorgio Vasari in the sixteenth century, while at the same time espousing a classical theory of artistic creation that has often been seen as the foundation of academic classicism, popular well into the nineteenth century. He is, in other words, an immensely significant figure, as a source of information on artists' lives, and, more importantly, as a cogent, early spokesperson for one of the dominant aesthetic modes of Western European culture.Given this importance, the relative dearth of publications dedicated toBellori, especially in the Anglo-American world, is surprising. PerhapsBellori's famously negative assessment of Caravaggio, or his complete avoidance of two of the most successful Italian artists of the seventeenth century, Pietro da Cortona and Gian Lorenzo Bernini, account for the scarcity ofscholarly treatments, or maybe his supposed insistence that all great art should be grounded in rules is to blame. The reasons are hard to pin down, but the volume of essays under consideration here goes some significant way towards rectifying the situation. Stemming from a 1996 conference organized by the Association for Textual Scholarship in Art History and held at the American Academy in Rome, the volume is divided into two roughly equal sections, one on "Bellori and the Republic of Letters in Seventeenth-Century Rome," and the other on "Bellori's Lives: History, Criticism, Theory." It comprises twelve essays, including a long and very useful introduction by Janis Bell, one of the editors of the book. The overall goal of the collection is to treat Bellori's activity as a whole, rather than focus single-mindedly on the Lives. After all, as Bell points out, the preponderance of Bellori's publishing was not dedicated to aesthetic theory, or even artists' biographies, but to antiquarian studies. In this, the present volume is very different from the other major new work on Bellori, a two-volume cataloguepublished in 2000 to accompany anexhibition held at the Palazzo delle Esposizioni in Rome, L'idea del Bello: viaggio per Roma nel Seicento con Giovan Pietro Bellori. The exhibition did acknowledge Bellori's antiquarian interests, but was aimed principally at something else: making visible his aesthetic theory. Unfortunately, the authors of Art History in the Age of Belloriwere not able to take into account fully [End Page 116] the conclusions of this important study,although it should be noted that several authors are represented in both publications.The first group of essays in the book, six in number, treats a wide range of themes, with the intention of crafting a context, both literary and political, for understanding Bellori's achievement. Giovanna Perini's essay, the first of section one, describes Bellori's career trajectory, and, more significantly, how this path had an impact on his life as a scholar. Bellori did not come from the wealthiest stratum of society. On the contrary, he was of relatively modest means, which meant that he had to rely on employment income. One implication of being economically beholden to his employers was that his writing had to conform to their political agendas. The Vite, for instance, are famous for lionizing the French artist Nicolas Poussin, of obvious appeal to his Francophile patrons. Diego Velázquez, however, was not included in the Vite, perhaps because he was Spanish and would thus have appealed to the opposing political faction in Rome at the time, which was linked to Spain. At the same time, Perini convincingly argues that Bellori's own voice was not drowned out in the process... (shrink)

Clive Bell’s Art, published in 1913, is widely seen as a founding document in contemporary aesthetics. Yet his formalism and his attendant definition of art as “significant form” is widely rejected in contemporary art discourse and in the philosophy of art. In this paper I argue for a reconsideration of his thought in connection with current discussions of “the aesthetics of everyday life.” Although some, notably Allen Carlson, have argued against application of Bell’s formalism to the aesthetics of (...) everyday life, I claim that this is based on an interpretation of the concept that is overly narrow. First, Li Zehou offers an interpretation of “significant form” that allows in sedimented social meaning. Second, Bell himself offers a more complex theory of significant form by way of his “metaphysical hypothesis,” one that stresses perception of significant form outside the realm of art. Bell’s idea that the artist can perceive significant form in nature allows for significant form to not just be the surface-level formal properties of things. It stresses depth, although a different kind than the cognitive scientific depth Carlson wants. This is a depth that is consistent with the anti-dualism of Spinoza, Marx and Dewey. Reinterpreting Bell in this direction, we can say we are moved by certain relations of lines and colors because they direct our minds to the hidden aspect of things, the spiritual side of the material world referred to by Spinoza and developed by Dewey in his concept of experience. Bell hardly “reduces the everyday to a shadow of itself,” as Carlson puts it, since the everyday, as experienced by the artist or the aesthetically astute observer, has, or potentially has, deep meaning. If we reject Bell’s dualism and his downgrading of sensuous experience, we can rework his idea of pure form to refer to an aspect of things detached, yes, from practical use, but not from particularity or sedimented meaning, not purified of all associations.

Despite the recent proliferation of scientific, clinical, and narrative accounts of auditory verbal hallucinations, the phenomenology of voice hearing remains opaque and undertheorized. In this article, we outline an interdisciplinary approach to understanding hallucinatory experiences which seeks to demonstrate the value of the humanities and social sciences to advancing knowledge in clinical research and practice. We argue that an interdisciplinary approach to the phenomenology of AVH utilizes rigorous and context-appropriate methodologies to analyze a wider range of first-person accounts of AVH (...) at 3 contextual levels: cultural, social, and historical; experiential; and biographical. We go on to show that there are significant potential benefits for voice hearers, clinicians, and researchers. These include informing the development and refinement of subtypes of hallucinations within and across diagnostic categories; “front-loading” research in cognitive neuroscience; and suggesting new possibilities for therapeutic intervention. In conclusion, we argue that an interdisciplinary approach to the phenomenology of AVH can nourish the ethical core of scientific enquiry by challenging its interpretive paradigms, and offer voice hearers richer, potentially more empowering ways to make sense of their experiences.

Since the validity of Bell's inequalities implies the existence of joint probabilities for non-commuting observables, there is no universal consensus as to what the violation of these inequalities signifies. While the majority view is that the violation teaches us an important lesson about the possibility of explanations, if not about metaphysical issues, there is also a minimalist position claiming that the violation is to be expected from simple facts about probability theory. This minimalist position is backed by theorems due (...) to A. Fine and I. Pitowsky.Our paper shows that the minimalist position cannot be sustained. To this end,we give a formally rigorous interpretation of joint probabilities in thecombined modal and spatiotemporal framework of `stochastic outcomes inbranching space-time' (SOBST) (Kowalski and Placek, 1999; Placek, 2000). We show in this framework that the claim that there can be no joint probabilities fornon-commuting observables is incorrect. The lesson from Fine's theorem is notthat Bell's inequalities will be violated anyhow, but that an adequate modelfor the Bell/Aspect experiment must not define global joint probabilities. Thus we investigate the class of stochastic hidden variable models, whichprima facie do not define such joint probabilities. The reasonwhy these models fail supports the majority view: Bell's inequalities are notjust a mathematical artifact. (shrink)

Many believe that the ethical problems of donation after cardiocirculatory death (DCD) have been "worked out" and that it is unclear why DCD should be resisted. In this paper we will argue that DCD donors may not yet be dead, and therefore that organ donation during DCD may violate the dead donor rule. We first present a description of the process of DCD and the standard ethical rationale for the practice. We then present our concerns with DCD, including the following: (...) irreversibility of absent circulation has not occurred and the many attempts to claim it has have all failed; conflicts of interest at all steps in the DCD process, including the decision to withdraw life support before DCD, are simply unavoidable; potentially harmful premortem interventions to preserve organ utility are not justifiable, even with the help of the principle of double effect; claims that DCD conforms with the intent of the law and current accepted medical standards are misleading and inaccurate; and consensus statements by respected medical groups do not change these arguments due to their low quality including being plagued by conflict of interest. Moreover, some arguments in favor of DCD, while likely true, are "straw-man arguments," such as the great benefit of organ donation. The truth is that honesty and trustworthiness require that we face these problems instead of avoiding them. We believe that DCD is not ethically allowable because it abandons the dead donor rule, has unavoidable conflicts of interests, and implements premortem interventions which can hasten death. These important points have not been, but need to be fully disclosed to the public and incorporated into fully informed consent. These are tall orders, and require open public debate. Until this debate occurs, we call for a moratorium on the practice of DCD. (shrink)

We shall discuss afterwards three possible interpretations of the experimental violation of these inequalities.

The word “emotion” has named a psychological category and a subject for systematic enquiry only since the 19th century. Before then, relevant mental states were categorised variously as “appetites,” “passions,” “affections,” or “sentiments.” The word “emotion” has existed in English since the 17th century, originating as a translation of the French émotion, meaning a physical disturbance. It came into much wider use in 18th-century English, often to refer to mental experiences, becoming a fully fledged theoretical term in the following century, (...) especially through the influence of two Scottish philosopher-physicians, Thomas Brown and Charles Bell. This article relates this intellectual and semantic history to contemporary debates about the usefulness and meaning of “emotion” as a scientific term. (shrink)

ABSTRACT Socioeconomic disparities between whites and blacks are pervasive in American society. Structuring of the discussion of these disproportions is the liberal race relations paradigm. According to Racial Liberalism, racial inequalities are an impermanent feature of American society because they are due primarily to race prejudice and discriminatory practices, which are continuously diminishing among whites. Challenging this view is Racial Realism. Racial Realism attributes the persistence of racial inequality to institutional privileges whites retain and refuse to relinquish whether or not (...) they are conscious of them. I argue that Racial Realism, with some qualification, is the better explanation for the persistence of racial inequality. Racial inequalities will persist, because American society and its entrenched institutions continue to affirm, white supremacy. (shrink)

In this article I investigate several possibilities to define the concept of “temporal non-locality” within the standard framework of quantum theory. In particular, I analyze the notions of “temporally non-local states”, “temporally non-local events” and “temporally non-local observables”. The idea of temporally non-local events is already inherent in the standard formalism of quantum mechanics, and Basil Hiley recently defined an operator in order to measure the degree of such a temporal non-locality. The concept of temporally non-local states enters as soon (...) as “clock-representing states” are introduced in the context of special and general relativity. It is discussed in which way temporally non-local measurements may find an interesting application for experiments which test temporal versions of Bell inequalities. (shrink)

Today, scientific biography is primarily thought of as a way of writing contextual history of science. But the genre has other functions as well. This article discusses seven kinds of ideal–typical subgenres of scientific biography. In addition to its mainstream function as an ancilla historiae, it is also frequently used to enrich the understanding of the individual construction of scientific knowledge, to promote the public engagement with science, and as a substitute for belles-lettres. Currently less acknowledged kinds of scientific biography (...) include its use as a medium for public and private, respectively, commemoration. Finally, the use of scientific biography as a research ethical genre, providing examples of ‘the good life in science’, is emphasized. (shrink)

Most of the nearly innumerable attempts to provide for a sound understanding of the gedanken experiment of Einstein, Podolsky, and Rosen (EPR) contain additional ideas, notions or features imposed on pioneer or traditional quantum mechanics (TQM). In the present paper the problem is analyzed without employing any new or philosophically contested concept. We do even without referring to the probability calculus, and we especially avoid any admixture of realistic ideas. Neither entanglement nor special features of “states” are used. Instead, formulating (...) strictly within the framework of TQM and using an ensemble approach, the crucial point is boiled down to the decision between separability and non-separability. The corresponding second-order correlation functions Δs and Δn−s, resp., which predict the experimental outcome, may differ by a factor of 2 if certain operator pairs are maximally non-commuting. Even in the case of commuting pairs, an experimentally relevant difference between the Δ-functions might exist. Taking into account the experimental evidence, it is unavoidable to accept that the sub-ensembles involved in EPR-type experiments are in fact non-separable. This result has been obtained without resort to Bell's inequality. (shrink)

A violation of Bell’s inequalities is generally considered to be the Holy Grail of experimental proof that a specific natural phenomenon cannot be explained in a classical framework and is based on a non-boolean structure of predications. Generalized quantum theory allows for such non-boolean predications. We formulate temporal Bell’s inequalities for cognitive two-state systems and indicate how these inequalities can be tested. This will introduce the notion of temporally non-local measurements. The Necker-Zeno model for bistable perception predicts a (...) violation of these temporal Bell’s inequalities. (shrink)

According to Zurek, the emergence of a classical world from a quantum substrate could result from a long selection process that privileges the classical bases according to a principle of optimal information. We investigate the consequences of this principle in a simple case, when the system and the environment are two interacting scalar particles supposedly in a pure state. We show that then the classical regime corresponds to a situation for which the entanglement between the particles (the system and the (...) environment) disappears. We describe in which circumstances this factorisability condition is fulfilled, in the case that the particles interact via position-dependent potentials, and also describe in appendix the tools necessary for understanding our results (entanglement, Bell inequalities and so on).

In lieu of an abstract, here is a brief excerpt of the content:Rhetoric in History as Theory and Praxis: A Blast from the PastThomas B. FarrellPhilosophies of history have fallen on hard times. Grand comic metanarratives were the first casualty, auguring ironically in the futility of their own pronouncements. Positive and negative teleologies were next to fall. But if finalized themes and Utopian schemes are not exactly in vogue, it remains the case that history—as systematic documentation and reminiscence about the (...) past—is and must be ongoing. This is transparently because things that matter continue to happen: with ideas, cultures, nature itself. And even if we never really learn from history, all other things being equal, history has shown that it is helpful to keep careful records. In an age that personalizes nearly everything, it is easy enough to recognize the familiar dissociation of act and accountability on a personal scale. What may appear as nothing more serious than petty truancy for a person may become amnesia, revisionism, and much worse when the zone of accountability is widened, the deeds are deepened, the stakes are increased. In each case, the argument is the same: identification through a sort of opaque empathy. In short, you had to be there.I intend this essay to be a meditation on some of the ways my amorphousarea of study, rhetorical theory, finds itself implicated with history, some possible avenues it may open for invention and judgment in history. Time permitting, I will also hazard a speculation on that great chimera [End Page 323] that dangles before fields of scholarship and historical projects alike: that of progress.Aristotle’s famous definition of rhetoric, “that its function is not to persuade but to see the available means of persuasion in each case” (1991, 35), begins my inquiry in a productively ambiguous way. For one thing, the definition locates the function of rhetoric directly within the sphere of human history, through the terms available and in each case. For unless we believe that means of persuasion are fixed and that cases are eternally recurring, what the rhetorician “sees” must vary with the times. A second note maybe in order here. For Aristotle’s term for seeing, theoresai, also happens to be the Greek root term for what we call “theory.” In its most fundamental sense, then, the ocular-centered aesthetic of Greek tradition gives us theory as a mode of “seeing.” I could add at this point that this “seeing” needs to be shared with others and that there are many ways of “seeing,” but this maybe a less-than-productive ambiguity, given my aims here.Instead, I wish to consider three distinct construals of what sort of practice rhetoric is, along with some implications of these construals for the place of rhetoric as theory and practice in human history. These three construals are rhetoric as productive art, rhetoric as constitutive art, and rhetoricas inventional art.We begin with the conception of rhetoric as productive art. Simply put, this means that rhetoric makes things, prototypically speeches. Such a conception, like the other two I will be discussing, has ebbed and flowed throughout the long history of rhetorical tradition. The Sophists, when not purporting to teach virtue, did profess their competence in instructing other show to create persuasive documents. Such a preoccupation also appears in rhetorics of belles lettres and elocution. Today it can be found in modern composition curricula and in the rather different world of the professional speechwriter.There have been very few attempts to link an exclusively productive art conception of rhetoric to Aristotle and still fewer successful attempts. To view the matter this way, one would need to think of the Rhetoric and the Poetics as essentially parallel documents (one makes poems; the other, speeches). One would also have to ignore a wealth of disconfirming evidence. Nonetheless, Alan G. Gross is able to write (in the aptly titled collection Rereading Aristotle’s “Rhetoric”), “‘What did Aristotle mean by rhetoric?’ At this juncture, I can do little more than reiterate my claim that rhetoric is a productive art, and only a productive art” (2000, 35). George Kennedy, the translator of our earlier passage, sees the matter rather differently: “What [End Page 324] kind of... (shrink)

Many argued (Accardi and Fedullo, Pitowsky) that Kolmogorov's axioms of classical probability theory are incompatible with quantum probabilities, and that this is the reason for the violation of Bell's inequalities. Szabó showed that, in fact, these inequalities are not violated by the experimentally observed frequencies if we consider the real, “effective” frequencies. We prove in this work a theorem which generalizes this results: “effective” frequencies associated to quantum events always admit a Kolmogorovian representation, when these events are collected through (...) different experimental setups, the choice of which obeys a classical distribution.

Quantum mechanics predicts non-local correlations in spatially extended entangled quantum systems, and these correlations are empirically very well confirmed. This raises philosophical questions of how nature could be that way, prompting the study of purported completions of quantum mechanics by hidden variables. Bell-type theorems connect assumptions about hidden variables with empirical predictions for the outcome of quantum correlation experiments. From among these assumptions, the Setting Independence assumption has received the least formal attention. Its violation is, however, central in the (...) recent discussion about super-deterministic models for quantum correlation experiments. In this paper, we focus on the non-local modal correlations in the GHZ experiment. We model the introduction of hidden variables in the form of instruction sets via structure extensions in the framework of Branching Space-Times. This framework allows us to show in formal detail how the introduction of non-contextual instruction sets results in a specific violation of Setting Independence; a similar result is derived for contextual instruction sets. Our discussion provides additional reasons for foregoing the introduction of local hidden variables, and for accepting non-local quantum correlations as a resource provided by nature. (shrink)

A novel conceptual framework for theoretical psychology is presented and illustrated for the example of bistable perception. A basic formal feature of this framework is the non-commutativity of operations acting on mental states. A corresponding model for the bistable perception of ambiguous stimuli, the Necker–Zeno model, is sketched and some empirical evidence for it so far is described. It is discussed how a temporal non-locality of mental states, predicted by the model, can be understood and tested.

This book explores and articulates the concepts of the continuous and the infinitesimal from two points of view: the philosophical and the mathematical. The first section covers the history of these ideas in philosophy. Chapter one, entitled ‘The continuous and the discrete in Ancient Greece, the Orient and the European Middle Ages,’ reviews the work of Plato, Aristotle, Epicurus, and other Ancient Greeks; the elements of early Chinese, Indian and Islamic thought; and early Europeans including Henry of Harclay, Nicholas of (...) Autrecourt, Duns Scotus, William of Ockham, Thomas Bradwardine and Nicolas Oreme. The second chapter of the book covers European thinkers of the sixteenth and seventeenth centuries: Galileo, Newton, Leibniz, Descartes, Arnauld, Fermat, and more. Chapter three, 'The age of continuity,’ discusses eighteenth century mathematicians including Euler and Carnot, and philosophers, among them Hume, Kant and Hegel. Examining the nineteenth and early twentieth centuries, the fourth chapter describes the reduction of the continuous to the discrete, citing the contributions of Bolzano, Cauchy and Reimann. Part one of the book concludes with a chapter on divergent conceptions of the continuum, with the work of nineteenth and early twentieth century philosophers and mathematicians, including Veronese, Poincaré, Brouwer, and Weyl. Part two of this book covers contemporary mathematics, discussing topology and manifolds, categories, and functors, Grothendieck topologies, sheaves, and elementary topoi. Among the theories presented in detail are non-standard analysis, constructive and intuitionist analysis, and smooth infinitesimal analysis/synthetic differential geometry. No other book so thoroughly covers the history and development of the concepts of the continuous and the infinitesimal. (shrink)

Les notions de «mort» et de «mourir», parfois utilisées sans distinctions dans la littérature, font référence à deux dimensions fort différentes pour la personne en fin de vie, de même que pour toutes les personnes appelées à en prendre soin .

Si l’espoir de «connaître une belle mort» se conçoit aisément, le mourir n’en demeure pas moins le moment le plus tragique de l’existence humaine. (shrink)

La mécanique quantique est une théorie physique contemporaine réputée pour ses défis au sens commun et ses paradoxes. Depuis bientôt un siècle, plusieurs interprétations de la théorie ont été proposées par les physiciens et les philosophes, offrant des images quantiques du monde, ou des ontologies, radicalement différentes.

Après avoir discuté de la définition de l'interprétation d'une théorie physique, ce livre présente trois principales interprétations (...) quantiques, empiriquement équivalentes : l'interprétation dite orthodoxe, l'interprétation de Bohm, et l'interprétation des mondes multiples.
