Following Dirac's generalized canonical formalism, we develop a quantization scheme for theN-dimensional system described by the Lagrangian $L_0 (\dot y,y) = \frac{1}{2}h_{ij} (y)\dot y^i \dot y^j + b_i (y)\dot y^i - w(y)$ which is supposed to be invariant under the gauge transformation $y^i \to y\prime ^i = y^i + (\rho ^i _\alpha + \sigma ^i _{\alpha j} \dot y^j )\delta \Lambda ^\alpha + \tau ^i _\alpha \delta \dot \Lambda ^\alpha$ . The gauge invariance necessarily implies that the Lagrangian is singular. (...) The identities imposed by the gauge invariance are enumerated and reduced to simpler forms. There are primary and secondary constraints, both of which are of first class. The reduced identities are solved explicitly for the case where the secondary constraints constitute the generators of the groupSO(M), and thus an explicit expression for the manifestly gauge-invariant Lagrangian is obtained. By fixing the gauge appropriately, the unphysical variables are eliminated and a quantization is achieved using only physical variables. Our formulation is covariant under an arbitrary point transformation of physical variables. The problem of formulating a quantum action principle is also commented on briefly. (shrink)

Schwinger's action principle is formulated for the quantum system which corresponds to the classical system described by the LagrangianL c( $\dot x$ , x)=(M/2)gij(x) $\dot x$ i $\dot x$ j−v(x). It is sufficient for the purpose of deriving the laws of quantum mechanics to consider onlyc-number variations of coordinates and time. The Euler-Lagrange equation, the canonical commutation relations, and the canonical equations of motion are derived from this principle in a consistent manner. Further, it is shown that an arbitrary point (...) transformation leaves the forms of the fundamental equations invariant. The judicious choice of the quantal Lagrangian is essential in our formulation. A quantum mechanical analog of Noether's theorem, which relates the invariance of the quantal action with a conservation law, is established. The ambiguities in the quantal Lagrangian are also discussed and it is pointed out that the requirement of invariance is not sufficient to determine uniquely the quantal Lagrangian and the Hamiltonian.

Studies with primates in sequence production tasks reveal that chimpanzees make action plans before initiating responses and making on-line adjustments to spatially exchanged stimuli, whereas such planning isn't evident in monkeys. Although planning may rely on phylogenetically newer regions in the inferior parietal lobe – along with the frontal lobes and basal ganglia – it dates back to as far as five million years ago.

A scholium in codex Vaticanus graecus 156 provides evidence that Cassius Dio's Roman History once contained an explicit reference to the ludi saeculares of a.d. 204, something that has been denied in recent scholarship.

Recoiling from the power that Athenian democracy placed in the hands of the poor, the founding fathers of the United States took Athens as primarily an anti-model, whereas nineteenth-century defenders of slavery found Athens a very congenial model indeed, seeming as it did to lend a mantle of legitimacy to an unspeakable practice. After a “honeymoon period” in which democracy was idealized as the only legitimate form of government, now at the outset of the twenty-first century the alliance of democracy (...) with a capitalism that often proves heartless to the less fortunate has raised some troubling questions about democracy itself. Despite its small size, classical Athens offers valuable guidance for tempering current difficulties in both the United States and elsewhere by adopting and adapting the selection of some officials by sortition, direct election by popular vote of elected officials, a rigorous system of accountability, and the fostering of civic and community values.

In a time of increasing polarization, how can we address sensitive topics and ensure that university classrooms remain places of healthy discussions and ethical deliberations? This paper addresses this important question by drawing on unique qualitative data from our students’ accounts of their experience in an organizational ethics course. We developed the course using a novel pedagogical strategy centered around the creation of an artistic portfolio. We find that student engagement in an alternative individual space, such as the artistic portfolio, (...) supports them in developing (inter)personal skills in preparation for constructive participation in sensitive discussions and ethical deliberation in the classroom. Additionally, engagement with the artistic portfolio provides them with an alternative means for alleviating tension that arises from these discussions and a space for expressing their opinions. Our findings highlight the role of the portfolio as an individual safe haven that supports teachers in facilitating a positive classroom atmosphere and guides students through challenging discussions and deliberations intrinsic to responsible management education. Considering these new insights, we advocate for a shift from a collective to an individual perspective on safety in academia. This transition liberates the classroom from the constraints and limitations often associated with the establishment of collective safe spaces. (shrink)

Kat Williams and Scott R. Stroud’s essay is about televised debates, but it is also about the value of television in a democracy. In Amusing Ourselves to Death, Neil Postman argues that television is devoid of serious content, that it is superficial. But while the debates contain superficialities, they also reveal substantive issues about the candidates, the electorate, and the state of our democracy.

Philosophy textbook for Mongolian undergraduate and post-graduate students.

Cosmological arguments for the existence of God face a gap problem. This is the problem of convincingly arguing that their intermediate conclusions that some first cause or necessary being exists provide evidence for their main conclusion that God exists. This paper develops a simple and innovative approach to solving this problem, applicable to many cosmological arguments. According to the proposal, the best explanation for why the necessary being is found to have necessary existence is that it is a perfect being. (...) Since a perfect being would be God, the intermediate conclusions of the relevant cosmological arguments provide abductive evidence for their main conclusions. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:354 BOOK REVIEWS (continuously) revisable character, he falls back on an account of theology as rhetoric so as to make the best of a bad job. For persuasion is what we use when we know demonstration is hopeless. As a result, Professor Cunningham's study, which could most usefully have "placed" a variety of theologies of past, present, and, prospectively, future on the spectrum of (onto-) logic, poetic, and rhetoric, (...) concludes instead that theology must regard itself as rhetorical or perish! This inevitably narrows the several services theologies of different kinds can perform for the Church. Imagine how biblical studies would be reduced were the exegete only to treat his text as paraenesis, and never as history or as a symbolic world. Nonetheless, on the way from its (as I find) unsatisfactory startingpoint and to its depressing conclusion, Faithful Persuasion has worthwhile points to make about a number of authors (of various periods) and topics, though it might have made them more persuasively (its author's key term) had the intended audience (middle-brow or academic?) been more clearly viewed in advance. AIDAN NICHOLS, O.P. Blackfriars Cambridge, England Church and Culture: German Catholic Theology, 1860-1914. By THOMAS FRANKLIN O'MEARA, O.P. Notre Dame/London: University of Notre Dame Press, 1991. Pp. x + 260. $35.95 (cloth). " In 1925, Baden's Kultusminister, a Protestant, began an address to the Gorresgesellschaft in Heidelberg by describing this era: ' Brave men like Hertling, Schell, Julius Bachem, and Carl Muth, shook the German Catholic world in order to lead it out of its fortress, to lead it again into the midst of the life and activity of the entire people, even when this seemed at first strange and uncomfortable ' " (pp. 159f.). Even to many theologians, the era in question-the last four decades of the nineteenth century through the outbreak of the "Great War"is comparatively unknown. There has been, of course, renewed interest in prominent theological figures like John Henry Newman, but his German-speaking contemporaries are for the most part strangers to the English-speaking world. And this is the first reason why this book is important: it describes a forgotten world of a century or so ago, yet one whose theological problematic was strikingly similar to our own. The " contours " of this period, deftly described in the first part of this book, were both varied and complex. Politically speaking, during the nineteenth century, " Germany " changed from an assortment of BOOK REVIEWS 355 geographically contiguous minor and medium-sized states to an Empire dominated by Prussia. Such a political re.arrangement had ecclesiastical implications: Roman Catholics, who previously had been the majority in places like Bavaria found themselves a persecuted minority during the Kulturkampf under Bismarck. And like many other victims of persecution, Roman Catholics adopted a "fortress mentality"fearful of Berlin, which was influenced by both the Lutheran Reformation and the Enlightenment, and mesmerized by Rome, which was coming under the increasing influence of neoscholasticism in doctrine and ultramontanism in discipline. German Catholic theologians found themselves in a quandary: what direction should they take? Many, like Joseph Kleutgen, took refuge in Rome; a few, like Joseph Schnitzer, found the appeal of Berlin more attractive; still others, however, tried to steer an independent course in dialogue with the culture of their day. The second and major part of this book focuses on five such theologians: Matthias Joseph Scheeben, Alois Schmid, Paul Schanz, Herman Schell, and Carl Braig. Scheeben (1835-88), "the best known and the most read in the first half of the twentieth century " (p. 53), pursued an independent route in seeking a " transcendent synthesis " incorporating both patristic and idealist thought; indeed, his lengthy Mysteries of Christ"ianity continued to enjoy a certain popularity up till the time of Vatican II, though more as a resource for spiritual reading than as a work of systematic theology. Like Newman, Scheeben's thought was sui generis, "and inspired the most divergent evaluations " (p. 65) ; unlike Newman, Scheeben has few disciples today. In contrast to Scheeben, the other four theologians attempted to emerge from the " fortress " of Roman Catholic defensiveness and to engage the historical and philosophical currents of their age.

The article deals with the problem of the philosophy of interdisciplinarity, set forth in the work of the same name by J.K. Schmidt. The main goal the author sets for himself is to define the inner meaning of the concepts and goals of interdisciplinarity. In accordance with this, the tasks performed by the respective fields of work, divided into intrascientific and extrascientific. The first ones are related to fundamental research, rethinking the forms of scientific knowledge, methodologies, the relationship between man (...) and nature. The latter, embedded in social reality, are related to analysis of the problems of technoscience, knowledge production and science policy. Prof. Schmidt considers two approaches to interdisciplinarity: instrumental or strategic and critical-reflexive or communicative. The first of them is presented as a limited tool for solving actual problems of interdisciplinarity due to its proximity to soluchionism and its predominant focus on organizational and managerial problems of science. The critical-reflexive approach is, on the contrary, associated with a fundamental rethinking of the concept of knowledge. Interdisciplinarity is characteristic of the field of scientific research, while transdisciplinarity and its particular forms – object- and problem-oriented approaches – are associated with solving problems of the real world. The author conducts a comprehensive analysis of the problem of interdisciplinarity, analyzing the historical roots of technoscientific issues, assesses the current state of science, and proposes a paradigmatic ProTA program related to the realization of the predictive potential of the critical-reflexive approach to interdisciplinarity.

This book defends a comprehensive new vision of what addiction is and how people with addictions should be treated. The author argues that, in addition to physical and intellectual disabilities, there are volitional disabilities – disabilities of the will – and that addiction is best understood as a species of volitional disability. -/- This theory serves to illuminate long-standing philosophical and psychological perplexities about addiction and addictive motivation. It articulates a normative framework within which to understand prohibition, harm reduction, and (...) other strategies that aim to address addiction. The argument of this book is that these should ultimately be evaluated in terms of reasonable accommodations for addicted people and that the priority of addiction policy should be the provision of such accommodations. What makes this book distinctive is that it understands addiction as a fundamentally political problem, an understanding that is suggested by standard legal approaches to addiction, but which has not received a sustained defense in the previous philosophical or psychological literature. -/- This text marks a significant advance in the theory of addiction, one which should reshape our understanding of addiction policy and its proper aims.

The Art of Randomness teaches readers to harness the power of randomness (and Python code) to solve real-world problems in programming, science, and art through hands-on experiments-from simulating evolution to encrypting messages to making machine-learning algorithms. Each chapter describes how randomness plays into the given topic area, then proceeds to demonstrate its problem-solving role with hands-on experiments to work through using Python code.

Moral distress names a widely discussed and concerning clinician experience. Yet the precise nature of the distress and the appropriate practical response to it remain unclear. Clinicians speak of their moral distress in terms of guilt, regret, anger, or other distressing emotions, and they often invoke them interchangeably. But these emotions are distinct, and they are not all equally fitting in the same circumstances. This indicates a problematic ambiguity in the moral distress concept that obscures its distinctiveness, its relevant circumstances, (...) and how individual clinicians and the medical community should practically respond to it. We argue that, in a range of situations that are said to be morally distressing, the characteristic emotion can be well‐understood in terms of what Bernard Williams calls “agent‐regret.” We show what can thereby be gained in terms of a less ambiguous concept and a more adequate ethical response to this distinctive and complex clinician experience.

Explores mind-body philosophy from an Asian perspective.

This paper continues a recent exchange in this journal concerning explanationist accounts of epistemic justification. In the first paper in this exchange, Byerly argues that explanationist views judge that certain beliefs about the future are unjustified when in fact they are justified. In the second paper, McCain defends a version of explanationism which he argues escapes Byerly’s criticism. Here we contribute to this exchange in two ways. In the first section, we argue that McCain’s defense of explanationism against Byerly’s objection (...) is unsuccessful. Then, in the second section, we develop an independent objection to explanationism from a different direction. If our arguments in each section are sound, then not only do explanationist accounts of epistemic justification judge beliefs that are justified to be unjustified, but they judge beliefs that are unjustified to be justified. Explanationism faces problems on both sides. (shrink)

Many pantheists have claimed that their view of the divine is motivated by a kind of spiritual experience. In this paper, I articulate a novel argument, inspired by recent work on moral exemplarism, that gives voice to this kind of motivation for pantheism. The argument is based on two claims about the emotion of awe, each of which is defended primarily via critical engagement with empirical research on the emotion. I also illustrate how this pathway to pantheism offers pantheists distinctive (...) resources for responding to persistent objections to their view, and how it might lead to more exotic views incorporating pantheistic elements.
