The search for a quantum theory of the gravitational field is one of the great open problems in theoretical physics. This book presents a self-contained discussion of the concepts, methods and applications that can be expected in such a theory. The two main approaches to its construction - the direct quantisation of Einstein's general theory of relativity and string theory - are covered. Whereas the first attempts to construct a viable theory for the gravitational field alone, string theory assumes that (...) a quantum theory of gravity will be achieved only through a unification of all the interactions. However, both employ the general method of quantisation of constrained systems, which is described together with illustrative examples relevant for quantum gravity. There is a detailed presentation of the main approaches employed in quantum general relativity: path-integral quantisation, the background-field method and canonical quantum gravity in the metric, connection and loop formulations. The discussion of string theory centres around its quantum-gravitational aspects and the comparison with quantum general relativity. Physical applications discussed at length include the quantisation of black holes, quantum cosmology, the indications of a discrete structure of spacetime, and the origin of irreversibility. This book will be of interest to researchers and students working in relativity and gravitation, cosmology, quantum field theory and related topics. It will also be of interest to mathematicians and philosophers of science. (shrink)

The ontological status of esse cognitum was at the center of complex debates throughout the Scotist tradition (Alnwick vs. Aesculo, Mastri vs. Punch). This article investigates the Scotist Angelo Volpe’s discussion of esse cognitum enjoyed by possible creatures in the divine intellect. Volpe responds to two religious warnings, one against assuming any eternal real being for merely possible creatures, and a second against depriving God’s eternal knowledge of a corresponding object, since that would endanger this knowledge itself. Volpe opts for (...) a solution that allows possible creatures the status of beings of reason (entia rationis) due to their own ontological merit, and the status of real beings (entia realia) due to God’s knowing that they as possibles are not in opposition to real existence. He rejects the view that esse cognitum is a kind of being that holds a middle position between real being and being of reason. Volpe’s historical significance is emphasized. (shrink)

This book discusses Henry Odera Oruka's sage philosophy, rethinking it in light of recent debates in African philosophy and African Studies. The chapters engage perspectives from anthropology, literature, and postcolonial scholarship, questioning and exploring the relevance of sage philosophy for current challenges, including decolonialization.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Ideas 61.2 (2000) 263-283 [Access article in PDF] Contesting Metaphors and the Discourse of Consciousness in William James Jill M. Kress Ah, not to be cut off,not by such slight partitionto be excluded from the stars' measure.What is inwardness?What if not sky intensified,flung through with birds and deepwith winds of homecoming? --Rainer Maria Rilke William James's lifelong attention to questions about human mental (...) experience elucidates the development of the concept of consciousness through its realization in fields as disparate as natural science, radical empiricism, and religious mysticism. 1 Over the course of a career that both establishes and traverses disciplinary boundaries, James's work embodies tensions between scientific explanations for mental phenomena and the inescapability of metaphysical arguments. Jamesian psychology thus alternates between materialist and spiritualist assumptions of scientists and philosophers at the turn of the century, joining their compulsive investigations into the nature of consciousness. 2 Most readers [End Page 263] of James puzzle over the theoretical contradictions within his work, debating central philosophical dilemmas concerning the status of the conscious self. Perhaps the most paradoxical aspect of James's theories, his response to dualism, emerges as he attempts to negotiate ethereal explanations for consciousness with bodily processes. 3 The mind-body problem disrupts James's more delicately balanced theories, a disruption registered explicitly through the metaphors in his texts.Reading The Principles of Psychology (1890) alongside "Does 'Consciousness' Exist" (1904), this essay demonstrates how figurative language directs James's study of consciousness. I argue that metaphor does more than describe consciousness; metaphor constructs James's arguments, governs his conflicting theories of mind through a series of rhetorical configurations and provokes the continual reconstruction of his ideas of human subjectivity. Furthermore, while it is impossible for James to explain and to study consciousness without metaphor, he experiences great anxiety about using language, figurative or otherwise, to represent his object of study. The language becomes more powerful than his intentions or designs and, indeed, raises implications that James cannot control. James possesses a heightened awareness of what he crafts with words; he also, perhaps more penetratingly, acknowledges the inadequacy of any linguistic system to realize concepts thoroughly. 4 Struggling over appropriate "names" and "terms" for consciousness, James presupposes some clearly delineated concept around which we might wrap a verbal expression; yet he also seems painfully aware that every new metaphor launches an entirely new theory. Fluid and unpredictable, consciousness becomes like language itself, yielding its power precisely because it can be so many things at once. The ultimate principle of Jamesian consciousness seems to be its creative capacity; still, once James admits that the problem of consciousness is a problem of language, his carefully constructed designs begin to unravel. Though consciousness will be translated into James's notion of "pure experience" by the time he writes the radical empiricism [End Page 264] essays, James remains simultaneously committed to his figures (especially of the "stream of consciousness") and ambivalent about the account of consciousness that they provide. James helps create the modern self with its enhanced individuality, though his metaphors at once direct us inward to a centered, private self and propel us outward to find consciousness materializing in the fluxional cycle of the natural world.In presenting his initial theory of the stream of our thoughts, James argues for its coherence. His most famous metaphor of the "stream" of consciousness appears to saturate the varied material of the mind, its water washing over and through any distinctions or separations which the mind might present: Consciousness, then, does not appear to itself chopped up in bits. Such words as "chain" or "train" do not describe it fitly as it presents itself in the first instance. It is nothing jointed; it flows. A "river" or a "stream" are the metaphors by which it is most naturally described. In talking of it hereafter, let us call it the stream of thought, of consciousness, or of subjective life. 5James's desire to find words that are more "natural... (shrink)

Among the metaphors used in the target article are “musical instruments,” “water waves,” and other types of mechanical oscillators. The corresponding equations have inertial properties and lead to standing waves that depend on boundary conditions. Other, physiologically relevant quantities like refractory times are not contained in the mechanical oscillator model but occur naturally, for instance, in biological forest fire metaphors.

The target article provides stimulating evidence for culture in cetaceans but does not provide a coherent theoretical framework. We argue that a complex, adaptive systems approach not only can provide such a framework but also can contribute advanced data analysis and simulation methods. For humpback whale songs, we suggest the framework of to model the observed spatio-temporal dynamics.

Die Philosophie des Barockscotismus war einerseits durch die rückwärtsgewandte Anknüpfung an den mittelalterlichen Denker Johannes Duns Scotus, andererseits durch die Anknüpfung an die Entwicklung in der zeitgenössischen Scholastik, vor allem der Jesuitenscholastik, geprägt. Welche Art von Metaphysik hat diese besondere philosophiehistorische Konstellation hervorgebracht? Um diese Frage zu beantworten, analysiert die vorliegende Arbeit das Metaphysikwerk des wichtigsten Repräsentanten des frühneuzeitlichen Scotismus, Bartholomaeus Mastrius (1602-1673); sie erschließt außerdem eine Vielzahl von kaum bis gar nicht erforschten Metaphysikwerken aus der Franziskanerscholastik des 17. und (...) 18. Jahrhunderts. Das eigenartige, erstaunliche Vielfalt einschließende Profil einer in Vergessenheit geratenen philosophischen Tradition wird deutlich. Durch den Fokus auf ein philosophiehistorisches Phänomen außerhalb des Mainstreams leistet die Arbeit einen Beitrag zu einer differenzierteren Sichtweise der intellektuellen Kultur der europäischen Frühmoderne. Baroque-age Scotist philosophy was, on the one hand, characterised by recourse to the Medieval thinker John Duns Scotus and, on the other hand, by an adaptation to trends in contemporary scholasticism, first of all that of the Jesuits. What kind of metaphysics did this particular constellation within the history of philosophy produce? In order to answer this question, the present book analyses the work on metaphysics by the most important representative of early modern Scotism, Bartolomeo Mastri (1602-1673). In addition, the book investigates a multitude of scarcely or never studied works on metaphysics from the Franciscan scholastic tradition of the 17th and 18th centuries. The peculiar profile of a forgotten philosophical tradition with its astonishing plurality becomes apparent. By focusing on a phenomenon from the history of philosophy outside the mainstream, this work contributes to a more differentiated view on the intellectual culture in early modern Europe. (shrink)

This contribution builds on the idea of integrating truth-fulfilling entities into a truth-conditional semantics. It asks which kind of truth conditions are to be considered for statements of something being really there – as opposed to just being an intentional object. The adverbial theory of perception treats experiences, for example appearances (visual experiences), as ‘adverbially’ classified. As a further approach towards how an object is related to its appearance (being experienced visually), semantical externalism is considered. On this basis, it is (...) proposed that the notion of existence can be understood as a disposition to be experienced: y being really there is explicated as a disposition to experiences that are adverbially characterized as y-experiences. This approach helps to understand the different perspectives of the natural sciences and the arts and humanities. While the natural sciences are directed towards y, the arts and humanities primarily deal with y-experiences. (shrink)

The goal of this paper is to re-assess reflective equilibrium (“RE”). We ask whether there is a conception of RE that can be defended against the various objections that have been raised against RE in the literature. To answer this question, we provide a systematic overview of the main objections, and for each objection, we investigate why it looks plausible, on what standard or expectation it is based, how it can be answered and which features RE must have to meet (...) the objection. We find that there is a conception of RE that promises to withstand all objections. However, this conception has some features that may be unexpected: it aims at a justification that is tailored to understanding and it is neither tied to intuitions nor does it imply coherentism. We conclude by pointing out a cluster of questions we think RE theorists should pay more attention to. (shrink)

Content and substance (Gehalt) in music is the difficult theme of this volume. The central questions are: in what manner is music more than immanence, structure and autonomous meaning, and to what degree do "extramusical" ideas and conceptions shape the work so that more appears to be in it than music alone. This theme is above all relevant for contemporary music of the 21st century, as ever more composers are interested both in cultural discourse and in a content-orientation for their (...) music. This volume presents essays by twelve composers who were invited to ponder the relationship between musical structure and the substance of music in light of their own musical practices. (shrink)

The paper starts by exploring the negative contingencies that are associated with the core institution of capitalist societies, the labour contract: unemployment, poverty, and denial of autonomy. It argues that these are the three conditions that basic income schemes can help prevent. Next, the three major normative arguments are discussed that are raised by opponents of basic income proposals: the idle should not be rewarded, the prosperous don’t need it, and there are so many things waiting to be done in (...) the world. After demonstrating that proponents of basic income stand in no way empty-handed when facing these objections, a third part considers basic income in functional terms: would its introduction help to resolve problems of social and economic order that are unlikely to be resolved in more conventional ways?

This book examines the theological methodology of Dutch theologian, Herman Bavinck (1854-1921). The focus of the book is on the influence of the German historicist movement on his theological method and uses Bavinck's doctrine of the Trinity as a way to test the argument that while not embracing all of the relativising implications of the movement, the role of history as a force that both shapes the present and allows for development into the future has a demonstrable influence on his (...) theological methodology. To make this argument the book considers Bavinck's larger nineteenth century context. It traces the development of both history and theology being understood as sciences in the university and how this required a reimagining of both disciplines. It could be said that the theology is thoroughly historicised in the nineteenth century. The book then considers the three principia of Bavinck's theological methodology: Revelation, Confession, and Christian Consciousness, demonstrating how Bavinck both appropriates and adapts historicist assumptions.

This book deals with the role of international standards for corporate governance in the context of corporate social responsibility. Based on the fundamentals of moral theory, the book examines governance and CSR in general, addressing questions such as: Is "good governance" not affected by moral concerns? How do the principles and practices of CSR standards adhere to or conflict with insights from business ethics and moral theory? To what extent do the standards and governance models provide normative guidance? Do the (...) standards and governance guidelines provide an adequate means of benchmarking and auditing? Are these standards a help or a hindrance to stakeholder engagement and transparency? The book provides insightful and thought-provoking answers to these and many other important questions concerning CSR standards, and offers a valuable resource for practitioners, academics and students at business schools and other institutions.

According to the predictive coding theory of psychosis, hallucinations and delusions are explained by an overweighing of high-level prior expectations relative to sensory information that leads to false perceptions of meaningful signals. However, it is currently unclear whether the hypothesized overweighing of priors represents a pervasive alteration that extends to the visual modality and takes already effect at early automatic processing stages. Here, we addressed these questions by studying visual perception of socially meaningful stimuli in healthy individuals with varying degrees (...) of psychosis proneness. In a first task, we quantified participants’ prior for detecting faces in visual noise using a Bayesian decision model. In a second task, we measured participants’ prior for detecting direct gaze stimuli that were rendered invisible by continuous flash suppression. We found that the prior for detecting faces in noise correlated with hallucination proneness as well as delusion proneness. The prior for detecting invisible direct gaze was significantly associated with hallucination proneness but not conclusively with delusion proneness. Our results provide evidence for the idea that overly strong high-level priors for automatically detecting socially meaningful stimuli might constitute a processing alteration in psychosis. (shrink)

What is life? Is it just the biologically familiar--birds, trees, snails, people--or is it an infinitely complex set of patterns that a computer could simulate? What role does intelligence play in separating the organic from the inorganic, the living from the inert? Does life evolve along a predestined path, or does it suddenly emerge from what appeared lifeless and programmatic? In this easily accessible and wide-ranging survey, Claus Emmeche outlines many of the challenges and controversies involved in the dynamic (...) and curious science of artificial life. Emmeche describes the work being done by an international network of biologists, computer scientists, and physicists who are using computers to study life as it could be, or as it might evolve under conditions different from those on earth. Many artificial-life researchers believe that they can create new life in the computer by simulating the processes observed in traditional, biological life-forms. The flight of a flock of birds, for example, can be reproduced faithfully and in all its complexity by a relatively simple computer program that is designed to generate electronic "boids." Are these "boids" then alive? The central problem, Emmeche notes, lies in defining the salient differences between biological life and computer simulations of its processes. And yet, if we can breathe life into a computer, what might this mean for our other assumptions about what it means to be alive? The Garden in the Machine touches on every aspect of this complex and rapidly developing discipline, including its connections to artificial intelligence, chaos theory, computational theory, and studies of emergence. Drawing on the most current work in the field, this book is a major overview of artificial life. Professionals and nonscientists alike will find it an invaluable guide to concepts and technologies that may forever change our definition of life. (shrink)

Cultures and moral expectations differ around the globe, and so the management of corporate responsibilities has become increasingly complex. Is there, however, a humanistic consensus that can bridge cultural and ethnic divides and reconcile the diverse and contrary interests of stakeholders world-wide? This book seeks to answer that question.

In summary, the creation and maintenance of the Wistar Rats as standardized animals can be attributed to the breeding work of Helen Dean King, coupled with the management and husbandry methods of Milton Greenman and Louise Duhring, and with supporting documentation provided by Henry Donaldson. The widespread use of the Wistar Rats, however, is a function of the ingenuity of Milton Greenman who saw in them a way for a small institution to provide service to science. Greenman's rhetoric, as captured (...) in his Director's Reports, prepared annually from 1905 until his death in 1937, shows that he was unusually sensitive to his times and to the economics of science and of society. In the era when biology was being defined, he recognized in the rat the potential to be a living analog to the pure chemicals that legitimated experimental science. From management literature he extracted the ideals of uniformity of product, standards of quality, and efficiency of production, applying them to scientific practice to generate an animal model that thrives as standard equipment in laboratories throughout the world today.I will close with a quote from Frederick W. Taylor that is a cogent statement of the contribution to science and scientific progress made by standardized tools and their creators. Equating the surgeon and the workman, Taylor wrote: [He is given] the finest implements, each one of which has been the subject of special study and development ... [and] the very best knowledge of his predecessors; and, provided with standard implements and methods which represent the best knowledge of the world up to date, he is able to use his own originality and ingenuity to make real additions to the world's knowledge, instead of reinventing things which are old.Standardized tools, whether surgeons' implements or laboratory-bred rats, are one of the vehicles for carrying scientific knowledge forward from generation to generation. In this sense, Greenman's Wistar Rats have done their job, in his words, of “providing service to science.”. (shrink)

The ancient virtue of practical wisdom has lately been enjoying a remarkable renaissance in management literature. The purpose of this article is to add clarity and bring synergy to the interdisciplinary debate. In a review of the wide-ranging field of the existing literature from a philosophical, theological, psychological, and managerial perspective, we show that, although different in terms of approach, methodologies, and justification, the distinct traditions of research on practical wisdom can indeed complement one another. We suggest a conciliatory conception (...) of the various features of practical wisdom in management. This we take as a point of departure for a discussion of the significant implications of the subject for the theory and practice of management and for the direction of further research in the field.

We develop a utilitarian framework to assess different decision rules for the European Council of Ministers. The proposals to be decided on are conceptualized as utility vectors and a probability distribution is assumed over the utilities. We first show what decision rules yield the highest expected utilities for different means of the probability distri- bution. For proposals with high mean utility, simple bench- mark rules (such as majority voting with proportional weights) tend to outperform rules that have been proposed in (...) the political arena. For proposals with low mean utility, it is the other way round. We then compare the expected utilities for smaller and larger countries and look for Pareto- dominance relations. Finally, we provide an extension of the model, discuss its restrictions, and compare our approach with assessments of decision rules that are based on the Penrose measure of voting power. (shrink)

The ability to read emotions in faces helps humans efficiently assess social situations. We tested how this ability is affected by aspects of familiarization with face masks and personality, with a focus on emotional intelligence. To address aspects of the current pandemic situation, we used photos of not only faces per se but also of faces that were partially covered with face masks. The sample, the size of which was determined by an a priori power test, was recruited in Germany (...) and consisted of healthy individuals of different ages [M = 24.8 years]. Participants assessed the emotional expressions displayed by six different faces determined by a 2 × 3 design. Each person was presented with six different emotional displays with or without a face mask. Accuracy and confidence were lower with masks—in particular for the emotion disgust but also for happiness, anger, and sadness. When comparing the present data collected in July 2021 with data from a different sample collected in May 2020, when people first started to familiarize themselves with face masks in Western countries during the first wave of the COVID-19 pandemic, we did not detect an improvement in performance. There were no effects of participants’ emotional intelligence, sex, or age regarding their accuracy in assessing emotional states in faces for unmasked or masked faces. (shrink)

Computer simulations are often claimed to be opaque and thus to lack transparency. But what exactly is the opacity of simulations? This paper aims to answer that question by proposing an explication of opacity. Such an explication is needed, I argue, because the pioneering definition of opacity by P. Humphreys and a recent elaboration by Durán and Formanek are too narrow. While it is true that simulations are opaque in that they include too many computations and thus cannot be checked (...) by hand, this doesn’t exhaust what we might want to call the opacity of simulations. I thus make a fresh start with the natural idea that the opacity of a method is its disposition to resist knowledge and understanding. I draw on recent work on understanding and elaborate the idea by a systematic investigation into what type of knowledge and what type of understanding are required if opacity is to be avoided and why the required sort of understanding, in particular, is difficult to achieve. My proposal is that a method is opaque to the degree that it’s difficult for humans to know and to understand why its outcomes arise. This proposal allows for a comparison between different methods regarding opacity. It further refers to a kind of epistemic access that is important in scientific work with simulations. (shrink)

Over the last two decades, network-focused approaches have become highly popular in diverse fields of biology, including neuroscience, ecology, molecular biology and genetics. While the network approach continues to grow very rapidly, some of its conceptual and methodological aspects still require a programmatic foundation. This challenge particularly concerns the question of whether a generalized account of explanatory, organisational and descriptive levels of networks can be applied universally across biological sciences. Consequently, the central focus of this theme issue will be on (...) the definition, motivation and application of key concepts in biological network science, such as levels, hierarchies, and explanatory directionality. A unification will be achieved by formulating norms for delimiting the distinctively network-topological class of explanations that connect general as well as very specific biological research questions. The impact of this theme issue is broad and encompassing, as it is highly interdisciplinary and opens a uniquely normative perspective on the foundational aspects of network-based explanations and modelling. This theme issue is intended to become a landmark publication for practical research as well as funding policy decisions, by unifying network approaches in biological sciences in terms of fundamental concepts and informing the public understanding of the network science.
