The statistical properties of a single quantum object and an ensemble of independent such objects are considered in detail for two-level systems. Computer simulations of dynamic zero-point quantum fluctuations for a single quantum object are reported and compared with analytic solutions for the ensemble case.

Reductionist explanations in biology generally assume that biological mechanisms are highly deterministic and basically similar between individuals. A contrasting view has emerged recently that takes into account the degeneracy of biological processes—the ability to arrive at a given endpoint by a variety of available paths, even within the same individual. This perspective casts significant doubt on the prospects for the ability to predict behavior accurately based on brain imaging or genotyping, and on the ability of neuroscience to stipulate ethics.

A theologian answers the question: What is the relationship between the hallucinogenic drugs, such as hashish, marihuana, mescaline, psilocybin, LSD, and both mysticism and morality?

Only a negative fundamental option, that is, the engagement of man's core awareness and freedom, can bring about the reality known as mortal sin.

In lieu of an abstract, here is a brief excerpt of the content:Big Women:Mark Adamo's Lysistrata, or the Nude Goddess Between Monteverdi and Musical ComedyRalph HexterWe live in an age when opera companies across America are regularly presenting new operas, and some of them are even making hesitant first steps into repertory status, though it is too soon to tell how long- or short-lived their performance history will be. Opera itself began—Peri's Dafne (1597) is commonly regarded as the starting point—as (...) an attempt to recreate Greek tragedy on the stage, and for at least its first two hundred years, plots drawing on classical material, if not always classical literary texts, were staples. Nineteenth-century opera composers were relatively less inclined to turn to the classics for plots and characters, but the twentieth century witnessed renewed activity in classically based operas, from Strauss' Elektra (1909) and Stravinsky's Oedipus Rex (1927) to Hans Werner Henze's Venus und Adonis (1997) and Randolph Peters' The Golden Ass (1999), to name but a few significant examples. Mark Adamo's Lysistrata, or the Nude Goddess, which premiered in Houston in 2005, is among the first operas in our new century to continue the tradition.Accompanied by a trio of distinguished distaff classicists, I attended the 2006 revival of Lysistrata, or the Nude Goddess at the New York City Opera. Some months later, as word of the outing—any resemblance to this or any other Aristophanic comedy is purely accidental—trickled out, AJP's editor asked me to write this "Brief Mention." The reader will infer, then, that I neither watched nor listened with the idea of writing such a notice. What follows are reflections based partially on recollection of my immediate impressions (especially of the music) but also on subsequent study of the published libretto,1 Adamo's earlier and quite popular Little Women (1998), and stray remarks of the composer in published or online [End Page 119] interviews. In no sense is it a review of the particular April 2nd matinee performance that I saw. Of that let me say that my impression was almost uniformly positive. The principals, who have very demanding parts (and not only vocally), were strong; several were reprising roles they had taken in the Houston world premiere.Adamo states on the title page of the libretto that the opera is "[f]reely adapted from the play by Aristophanes," and this is both true and to the good. Before I turn to the adaptation itself, it might be worth observing that within the reception history of ancient stageworks in opera, the tradition of classical comedies turned into operas is relatively slight. I put it that way because, of course, one might well argue that New Comedy in its Roman form is the ultimate source of all opera buffa. I say nothing new when I place Figaro directly in the line of servi callidi.2Greek Old Comedy (i.e., given the state of preservation, Aristophanes) has only infrequently provided fodder for opera. One of the most interesting cases is Walter Braunfels' setting of Aristophanes Birds—Die Vögel—premiered in 1920. Braunfels (1882–1954) was fired from his teaching post by the Nazis in 1933—he was half Jewish—and his works were banished from the repertory. Die Vögel, his most successful stagework, has been recently revived, and a recording is available in Decca's "Entartete ["degenerate"] Musik" series. One must also recall the famous Frogs performed in the pool of Yale's Payne Whitney Gymnasium in 1941, since, a generation later, in 1975, the piece was revived, provided with music and lyrics by Stephen Sondheim and, like so many other shows, transferred from New Haven (if not the Shubert) to Broadway.3Aristophanes is more at home, I would argue, in American musical comedy than in opera, at least opera as it has come to be received by modern audiences treated almost without exception to post-Gluckian opera, with major houses, until recently, shunning the more interesting hybrids. (Think even of Carmen and how long it took for it to lose the recitatives by Guiraud that replaced the original opéra comique spoken dialogue.) To modern spectators or readers, Aristophanes, with...

The life sciences in the 20th century were guided to a large extent by a reductionist program seeking to explain biological phenomena in terms of physics and chemistry. Two scientists who figured prominently in the establishment and dissemination of this program were Jacques Loeb in biology and Ivan P. Pavlov in psychological behaviorism. While neither succeeded in accounting for higher mental functions in physical-chemical terms, both adopted positions that reduced the problem of consciousness to the level of reflexes and associations. (...) The intellectual origins of this view and the impediment to the study of consciousness as an object of inquiry in its own right that it may have imposed on peers, students, and those who followed is explored.

In this paper, we discuss the macroscopic quantum behavior of simple superconducting circuits. Starting from a Lagrangian for electromagnetic field with broken gauge symmetry, we construct a quantum circuit model for a superconducting weak link (SQUID) ring, together with the appropriate canonical commutation relations. We demonstrate that this model can be used to describe macroscopic excitations of the superconducting condensate and the localized charge states found in some ultrasmall-capacitance weak-link devices.

We expand on the article “Ethical Challenges Arising in the COVID-19 Pandemic: An Overview from the Association of Bioethics Program Directors (ABPD) Task Force” to consider the ways in which rural...

Published in 1913 as _La Philosophie Bergsonienne_, this incisive critique of the thought of Henri Bergson was Jacques Maritain's first book. In it he shows himself already to have an authoritative grasp of the thought of St. Thomas Aquinas and an uncanny ability to demonstrate its relevance to alternative philosophical systems such as that of Henri Bergson. Volume 1 in the series _The Collected Works of Jacques Maritain_, this edition faithfully reproduces the 1955 translation published by the Philosophical Library. It (...) would be difficult to overestimate Bergson’s role in extricating French philosophy from the deadening materialism that dominated the Sorbonne. It was that cultural milieu that brought Maritain and his wife Raïssa to the brink of suicide. They drew back for two major reasons. First were the lectures of Henri Bergson at the Collège de France, in which the Maritains found a defense of metaphysics, of the transcendent beyond the material, within which they could find meaning in life. The second reason was their conversion to Catholicism, a move they and many of their contemporaries made after being introduced to Bergson’s work. Soon after his conversion, Jacques Maritain immersed himself in the thought of Thomas Aquinas and was struck by the comparative weaknesses of Bergson. This book is Maritain’s relentless criticism of the philosophy of the man whose lectures had meant so much to him. Its ferocity marks it as a young man’s book, written in part to exorcize the defects of Bergson’s philosophy as they were understood by one now schooled in Thomism. Twenty-five years later, Maritain, while not retracting his criticisms, regretted their intemperance and, as a result, moderated his assessment of Bergson in a long preface to the second edition. In it, we find a philosopher who mastered his craft and a critic of rare perception and refinement. (shrink)
