Part I. Gnosticism and other religious movements of antiquity -- part II. Crossing boundaries : Gnosticism and Platonism.

This book explores the intimate connections, conflicts and discontinuities between religion and philosophy in the Platonic and Neoplatonic traditions from Antiquity to the early Medieval period. It presents a broader comparative view of Platonism by examining the strong Platonist resonances among different philosophical/religious traditions, primarily Jewish, Christian, Islamic and Hindu, and suggests many new ways of thinking about the relation between these two fields or disciplines that have in modern times become such distinct and, at times, entirely separate domains.

Written in the form it discusses, _Reorienting Rhetoric _is both a narrative weaving out of a theme and a systematic treatment of a set of these ideas. The theme is the role of narration in the history of Western rhetoric. The ideas include the gradual tendency to privilege only systematic language, to discard all traditional modes of thinking, and to view narrative as an object but not as a means of thinking. _Reorienting Rhetoric_ argues that narration is a mode of (...) thinking as important as logic and that as narration goes, so goes rhetoric. O'Banion's perspective is heavily indebted to Quintilian, whose rhetorical question captures the essence of rhetorical thinking: "What difference is there between a proof and a statement of facts [narratio] save that the latter is a proof put forward in continuous form, while a proof is a verification of the facts as put forward in the statement?" Because narration has largely been ignored as a mode of thinking, O'Banion considers the gradually truncated role of narration in Western rhetorical, philosophical, and literary history; the resurgence of the importance of narrative in the twentieth century, especially in the work of Kenneth Burke; and the contributions of scholars in a variety of disciplines to understanding the importance of narrative and the limitations of logic for their fields of study and, inadvertently, for rhetoric.

In this paper, we examine whether ethics officers are able to perform their assigned duties independently of organizational management. Specifically, we investigate whether inherent conflicts of interest with company management potentially hinder the ability of ethics officers to serve as an effective monitor and deterrent of unethical activity throughout the organization. As part of our analysis, we conducted 10 detailed phone interviews with current and retired ethics officers in order to determine whether practicing ethics officers feel the need for additional (...) independence protection from management. We propose that the current system in which ethics officers report to management must be changed in order for ethics officers to effectively perform their jobs. Specifically, we maintain that ethics officers should (1) be hired by, (2) be fired by, and (3) report directly to the corporate board of directors rather than company management. Such a change in the reporting environment would greatly enhance the independence of ethics officers. (shrink)

An infinite lottery machine is used as a foil for testing the reach of inductive inference, since inferences concerning it require novel extensions of probability. Its use is defensible if there is some sense in which the lottery is physically possible, even if exotic physics is needed. I argue that exotic physics is needed and describe several proposals that fail and at least one that succeeds well enough.

The essays in this volume are concerned with our everyday and developed scientific systems of explanation of human behavior in terms of beliefs, attitudes,...

We introduce the computable FS-jump, an analog of the classical Friedman–Stanley jump in the context of equivalence relations on the natural numbers. We prove that the computable FS-jump is proper with respect to computable reducibility. We then study the effect of the computable FS-jump on computably enumerable equivalence relations (ceers).

1. Introduction. David Malament has described a natural and satisfying resolution of the traditional problems of Newtonian cosmology—natural in the sense that it effects the escape by altering Newtonian gravitation theory in a way that leaves its observational predictions completely unaffected. I am in full agreement with his approach. There is one part of his account, however, over which Malament has been excessively modest. The resolution requires a modification to Newtonian gravitation theory. Malament presents the modification as so straightforward as (...) to be automatic. This trivializes the crucial postulate, which I shall call the “relativity of acceleration.” It is a significant physical statement in its own right and requires careful justification. Moreover the postulate proved easy to overlook for decades of discussion of the paradox. It really only becomes natural from the perspective of the newer geometric methods Malament exploits. There the postulate has become a commonplace. My purpose here is to develop the following: While Newtonian cosmology can be repaired satisfactorily, in its traditional form it remains deeply troubled. These troubles can be expressed most vividly as the paradoxical contradictions indicated below. They persist in both the integral and differential formulations of Newtonian gravitation theory. Malament's careful geometric treatment is necessarily dense. By taking some liberties with precision, his core result can be expressed in a far simpler form. Attempts to avoid the resolution Malament describes do lead to disaster. Therefore this episode can be inverted and used as the strongest extant argument for the relativity of acceleration in Newtonian gravitation theory. (shrink)

We introduce a new family of jump operators on Borel equivalence relations; specifically, for each countable group [Formula: see text] we introduce the [Formula: see text]-jump. We study the elementary properties of the [Formula: see text]-jumps and compare them with other previously studied jump operators. One of our main results is to establish that for many groups [Formula: see text], the [Formula: see text]-jump is proper in the sense that for any Borel equivalence relation [Formula: see text] the [Formula: see (...) text]-jump of [Formula: see text] is strictly higher than [Formula: see text] in the Borel reducibility hierarchy. On the other hand, there are examples of groups [Formula: see text] for which the [Formula: see text]-jump is not proper. To establish properness, we produce an analysis of Borel equivalence relations induced by continuous actions of the automorphism group of what we denote the full [Formula: see text]-tree, and relate these to iterates of the [Formula: see text]-jump. We also produce several new examples of equivalence relations that arise from applying the [Formula: see text]-jump to classically studied equivalence relations and derive generic ergodicity results related to these. We apply our results to show that the complexity of the isomorphism problem for countable scattered linear orders properly increases with the rank. (shrink)

Our likes and dislikes--our senses and sensibilities--did not fall ready-made from the sky, argues internationally acclaimed author John D. Barrow. We know we enjoy a beautiful painting or a passionate symphony, but what we don't necessarily understand is that these experiences conjure up latent instincts laid down and perpetuated over millions of years. Now, in The Artful Universe, Barrow explores the close ties between our aesthetic appreciation and the basic nature of the Universe, challenging the commonly held view that (...) our sense of beauty is entirely free and unfettered. Barrow argues that the laws of the Universe, its environments and its astronomical appearance, have imprinted themselves upon our thoughts and actions in subtle and unexpected ways. Why do we like certain types of art or music? What games and puzzles do we find challenging? Why do so many myths and legends have common elements? Who created the cornucopia of constellations in the night sky? And why? In this eclectic and entertaining survey, Barrow answers these questions and more as he explains how the landscape of the Universe has influenced the development of philosophy and mythology, and how millions of years of evolutionary history have fashioned our attraction to certain patterns of sound and color. Barrow casts the story of human creativity and thought in a fascinating light, considering such diverse topics as our instinct for language, the origins and uses of color in Nature, why we divide time into intervals as we do, the sources of our appreciation of landscape painting, and whether computer-generated fractal art is really art. Barrow reconsiders the question of whether intelligent extraterrestrial life exists, showing that the benefits (and even the likelihood) that might follow from the discovery of life on other worlds could be very different from what we might have been led to expect. Remarkably, we find that some of the properties of the Universe that are essential for the existence of any form of life play a key role in determining psychological and religious responses to the Cosmos. Drawing on a wide variety of examples, from the theological questions raised by St. Augustine and C.S. Lewis to the relationship between the pure math of Pythagoras and the music of the Beatles, The Artful Universe covers new ground and enters a wide-ranging debate about the meaning and significance of the links between art and science. It will change our view of the creation of art and the way we see the world in which we live. (shrink)

In Leo Szilard’s 1929 thought experiment, a Maxwell demon manipulates a one-molecule gas to reverse the second law of thermodynamics. The demon must fail, Szilard argued, since there is hidden entropy creation in the demon’s collecting of information. This thought experiment is an inconsistent muddle of improper idealizations. It diverted an already successful literature of exorcism into degenerating speculations about about a connection between thermodynamic entropy and information. These confusions persist today in a voluminous literature. Narrative conventions in a thought (...) experiment allow thought experimenters great latitude in deciding which processes are typical and bear generalization and which can be idealized away as incidental. For its abuse of this latitude and the extent of the harm it caused, this thought experiment merits the distinction of the worst thought experiment in science. (shrink)

I am grateful to Peter Achinstein, Don Howard, and the other participants at the conference, 'The Role of Experiments in Scientific Changer', Virginia Polytechnic Institute and State University, 30 March to 1 April, 1990, for helpful discussion, and especially to Ron Laymon for his discussion comments presented at the conference on an earlier version of this paper.

How can we reconcile two claims that are now both widely accepted: Kretschmann's claim that a requirement of general covariance is physically vacuous and the standard view that the general covariance of general relativity expresses the physically important diffeomorphism gauge freedom of general relativity? I urge that both claims can be held without contradiction if we attend to the context in which each is made.

Both natural and engineered systems are fundamentally dynamical in nature: their defining properties are causal, and their functional capacities are causally grounded. Among dynamical systems, an interesting and important sub-class are those that are autonomous, anticipative and adaptive (AAA). Living systems, intelligent systems, sophisticated robots and social systems belong to this class, and the use of these terms has recently spread rapidly through the scientific literature. Central to understanding these dynamical systems is their complicated organisation and their consequent capacities for (...) re- and self- organisation. But there is at present no general analysis of these capacities or of the requisite organisation involved. We define what distinguishes AAA systems from other kinds of systems by characterising their central properties in a dynamically interpreted information theory. (shrink)

The thesis that observation necessarily fails to determine theory is false in the sense that observation can provide overwhelming evidence for a particular theory or even a hypothesis within the theory. The saga of quantum discontinuity illustrates the power of evidence to determine theory and shows how that power can be underestimated by inadequate caricatures of the evidential case. That quantum discontinuity can save the phenomena of black body radiation is the widely known result, but it leaves open the possibilities (...) of other accounts. That these phenomena, with the aid of minimal assumptions, entail quantum discontinuity is the crucial but now largely forgotten result. It was first demonstrated by Ehrenfest and Poincaré in 1911 and 1912. (shrink)

The inaugural title in the new, Open Access series BSPS Open, The Material Theory of Induction will initiate a new tradition in the analysis of inductive inference. The fundamental burden of a theory of inductive inference is to determine which are the good inductive inferences or relations of inductive support and why it is that they are so. The traditional approach is modeled on that taken in accounts of deductive inference. It seeks universally applicable schemas or rules or a single (...) formal device, such as the probability calculus. After millennia of halting efforts, none of these approaches has been unequivocally successful and debates between approaches persist. The Material Theory of Induction identifies the source of these enduring problems in the assumption taken at the outset: that inductive inference can be accommodated by a single formal account with universal applicability. Instead, it argues that that there is no single, universally applicable formal account. Rather, each domain has an inductive logic native to it. Which that is, and its extent, is determined by the facts prevailing in that domain. Paying close attention to how inductive inference is conducted in science and copiously illustrated with real-world examples, The Material Theory of Induction will initiate a new tradition in the analysis of inductive inference.

John D. Caputo explores the very roots of religious thinking in this thought-provoking book. Compelling questions come up along the way: 'What do I love when I love my God?' and 'What can Star Wars tell us about the contemporary use of religion?' Why is religion for many a source of moral guidance in a postmodern, nihilistic age? Is it possible to have 'religion without religion'? Drawing on contemporary images of religion, such as Robert Duvall's film _The Apostle_, Caputo (...) also provides some fascinating and imaginative insights into religious fundamentalism. (shrink)

Newtonian cosmology is logically inconsistent. I show its inconsistency in a rigorous but simple and qualitative demonstration. "Logic driven" and "content driven" methods of controlling logical anarchy are distinguished.

A substantial body of research has established that even when we are not consciously aware of the faces of others we are nevertheless sensitive to, and impacted by their facial expression. In this paper, we consider this body of research from a new perspective by examining the functions of unconscious perception revealed by these studies. A consideration of the literature from this perspective highlights that existing research methods are limited when it comes to revealing possible functions of unconscious perception. The (...) critical shortcoming is that in all of the methods, the perceived facial expression remains outside of awareness. This is a problem because there are good reasons to believe that one important function of unconsciously perceived negative faces is to attract attention so that they are consciously perceived; such conscious perception, however, is never allowed with existing methodologies. We discuss recent studies of emotional face perception under conditions of visual search that address this issue directly. Further, we suggest that methodologies that do not examine cognitive processes as they occur in more natural settings may result in fundamental misunderstandings of human cognition. (shrink)

Written with poignancy and compassion, Do We Still Need Doctors? is a personal account from the front lines of the moral and political battles that are reshaping America's health care system. Using compelling firsthand experiences, clinical vignettes, and moral arguments, John D. Lantos, a pediatrician, asks whether, as we proceed with the redesign of our health care system, doctors will -- or should -- continue to fulfill the roles and responsibilities that they have in the past. Interspersing moving personal (...) stories of his young patients suffering from AIDS, cancer, and other chronic or terminal illnesses with his own stirring dilemmas of truth telling, creative navigation of HMO bureaucracy, and reflections on the identity crisis of medical education, Dr. Lantos reveals how changes in out health care system and new technologies are fostering new ways of understanding and responding to illness. He taps into the public's sense of wanting doctors and hospitals to do something other than what they do now and the frustrating disagreement about what they should do in the future. (shrink)

Sadi Carnot’s 1824 Reflections on the Motive Power of Fire created the new science of thermodynamics. It succeeded in its audacious goal of finding a very general theory of the efficiency of heat engines, by introducing and exploiting the strange and unexpected notion of a thermodynamically reversible process. The notion is internally contradictory. It requires the states of these processes to be both in unchanging equilibrium, with a perfect balance of driving forces, while also changing. The work of Sadi’s father, (...) Lazare Carnot, on the efficiency of ordinary machines provided Sadi with a template of a very general theory of the efficiency of ordinary machines; and a characterization of the most efficient processes in them as those that minimize differences of driving forces and can be run in reverse. Lazare’s work could provide these resources because of its choice of a dissipative ontology of inelastic collisions among hard bodies. This historically ill-fated choice meant that Lazare’s machines were analogous to Sadi’s heat engines in their key aspects: they are built from essentially dissipative processes. Lazare’s strategies for controlling dissipation and optimizing his machines were transferrable to the analogous problems Sadi found in heat engines. The unanswerable historical question is whether Sadi would have sought a general theory of heat engines at all or found these general theoretical devices without the template provided in analogy by the prior work of Lazare.

In this commentary, I critically discuss the respective views of Gert and Beauchamp–Childress on the nature of so-called common morality and its promise for enriching ethical reflection within the field of bioethics. Although I endorse Beauchamp and Childress’ shift from an emphasis on ethical theory as the source of moral norms to an emphasis on common morality, I question whether rouging up common morality to make it look like some sort of ultimate and universal foundation for morality, untouched by the (...) dialectics of time and reflective equilibrium, was an equally good move. As for Gert’s magisterial conception of common morality, I conclude that certain elements of his system are controversial at best and woefully inadequate at worst. He has a tendency to find in common morality what he himself put there, and his highly restricted conception of duties of assistance strikes this reader as ad hoc, inadequately defended, and unworthy of a project whose goal is to lessen the amount of misery in the world.
