The foundations of Wesson’s induced matter theory are analyzed. It is shown that the empty—without matter—5-dimensional bulk must be regarded as a Weylian space rather than as a Riemannian one. Revising the geometry of the bulk, we have assumed that a Weylian connection vector and a gauge function exist in addition to the metric tensor. The framework of a Weyl–Dirac version of Wesson’s theory is elaborated and discussed. In the 4-dimensional hypersurface (brane), one obtains equations describing both fields, the gravitational (...) and the electromagnetic. The result is a geometrically based unified theory of gravitation and electromagnetism with mass and current induced by the bulk. In special cases on obtains on the brane the equations of Einstein–Maxwell, or these of the original induced matter theory. (shrink)

The Weyl theory of gravitation and electromagnetism, as modified by Dirac, contains a gauge-covariant scalar β which has no geometric significance. This is a flaw if one is looking for a geometric description of gravitation and electromagnetism. A bimetric formalism is therefore introduced which enables one to replace β by a geometric quantity. The formalism can be simplified by the use of a gauge-invariant physical metric. The resulting theory agrees with the general relativity for phenomena in the solar system.

Elementary particles, regarded as the constituents of quarks and leptons, are described classically in the framework of the general relativity theory. There are neutral particles and particles having charges±1/3e. They are taken to be spherically symmetric and to have mass density, pressure, and (if charged) charge density. They are characterized by an equation of state P=−ρ suggested by earlier work on cosmology. The neutral particle has a very simple structure. In the case of the charged particle there is one outstanding (...) model described by a simple analytic solution of the field equations. (shrink)

An integrable version of the Weyl-Dirac geometry is presented. This framework is a natural generalization of the Riemannian geometry, the latter being the basis of the classical general relativity theory. The integrable Weyl-Dirac theory is both coordinate covariant and gauge covariant (in the Weyl sense), and the field equations and conservation laws are derived from an action integral. In this framework matter creation by geometry is considered. It is found that a spatially confined, spherically symmetric formation made of pure geometric (...) quantities is a massive entity. This may be treated either as a fundamental particle or as a cosmic body. In an F-R-W universe at the very beginning of the expansion phase the cosmic matter is created from an initial Planckian egg made of geometry, and during the following expansion geometric fields continue to stimulate the matter production. (shrink)

Issuing from a geometry with nonmetricity and torsion we build up a generalized classical electrodynamics. This geometrically founded theory is coordinate covariant, as well as gauge covariant in the Weyl sense. Photons having arbitrary mass, intrinsic magnetic currents, (magnetic monopoles), and electric currents exist in this framework. The field equations, and the equations of motion of charged (either electrically or magnetically) particles are derived from an action principle. It is shown that the interaction between magnetic monopoles is transmitted by massive (...) photons. On the other hand, the photon is massive only in the presence of magnetic currents. We obtained a static spherically symmetric solution, describing either the Reissner-Nordstrom metric of an electric monopole, or the metric and field of a magnetic monopole. The latter must be massive. In the absence of torsion and in the Einstein gauge one obtains the Einstein-Maxwell theory. (shrink)

In order to get to a geometrically based theory of gravitation and electromagnetism, a gauge covariant bimetric tetrad space-time is introduced. The Weylian connection vector is derived from the tetrads and it is identified with the electromagnetic potential vector. The formalism is simplified by the use of gauge-invariant quantities. The theory contains a contorsion tensor that is connected with spinning properties of matter. The electromagnetic field may be induced by conventional sources and by spinning matter. In absence of spinning matter, (...) the equations are identical with those of the gauge-covariant bimetric theory.(23). (shrink)

A spherically symmetric entity with the Weyl-Dirac geometry holding in its interior is investigated. The structure is determined by the presence of the Dirac gauge function, which creates a mass density. Two models are obtained, one that can describe a cosmic body, the other an elementary particle.

It is suggested that the dark matter of the universe is due to the presence of a scalar field described by the gauge function introduced by Dirac in his modification of the Weyl geometry. The behavior of such dark matter is investigated.

Spherically symmetric entities filled with matter and induced by the 5D bulk may be built in the empty 4D space-time. The substance of the entity, the latter regarded as a fundamental particle, is characterized by the prematter equation of state P=−ρ. The particle is covered in a Schwarzschild-like envelope and from the outside it is characterized by mass and radius. One can regard these entities as neutral fundamental particles being constituents of quarks and leptons. The presented classical models are developed (...) in the framework of a Weyl–Dirac version of Wesson’s Induced Matter Theory. (shrink)

The problem of measurement in theories based on geometry with nonmetricity and contorsion is analyzed. In order to enable the use of atoms as measuring standards, one has to remove the nonintegrability of length in the interior of atoms. Geometrical descriptions appropriate fo this purpose are found in the general case and in the case of two-covariant theories.

In Weyl’s geometry the nonintegrability problem and difficulties in defining measuring standards are reconsidered. Approaches removing the nonintegrability of length in the interior of atoms are given, so that atoms can serve as measuring standards. The Weyl space becomes a well founded framework for classical theories of electromagnetism and gravitation.

It is shown that all spherically symmetric distributions of prematter in the framework of general relativity are static. These results provide a justification for the models of elementary particles proposed previously.

Einstein's approach to unified field theories based on the geometry of distant parallelism is discussed. The simplest theory of this type, describing gravitation and electromagnetism, is investigated. It is found that there is a charge-current density vector associated with the geometry. However, in the static spherically symmetric case no singularity-free solutions for this vector exist.

The Bible ridicules idolaters for bowing down to sticks and stones. Since idolaters worship what the sticks and stones stand for, not the sticks and stones themselves, isn’t the biblical position confused? At the basis of the Bible’s consistent refusal to observe the preceding distinction are found the conceptual underpinnings of its critique of idolatry. Men and women alone among creatures are inspired with God’s breath. Men and women alone among creatures, that is, are like God. They alone among creatures (...) are persons. Since mere pieces of nature cannot understand prayers, entreaties, etc., and hence cannot respond in the personal way, idolatrous practices are incoherent. But while it is true that (sub-person) elements of nature cannot enter into inter-personal relations, idolatry has a sequel: the scientific interrogation of nature, an interrogation which has been magnificently effective in eliciting responses. Elijah’s dramatic confrontation with the Baalites is a stylized version of the clash between the biblical view of men and women as in an irreducible respect non-natural, and the naturalizing scientific view. On the Carmel, the prophets of the Baal are soundly defeated. Must those who inherit from them lose too? That is a live question. Read closely, the story of Elijah implies that those behind the Bible would defend the view of human distinctiveness against the renascent idolatry. (shrink)

How can Scripture address the crucial justice issues of our time? In this book Mark Brett offers a careful reading of biblical texts that speak to such pressing public issues as the legacies of colonialism, the demands of asylum seekers, the challenges of climate change, and the shaping of redemptive economies. Brett argues that the Hebrew Bible can be read as a series of reflections on political trauma and healing -- the long saga of successive ancient empires violently asserting (...) their sovereignty over Israel and of the Israelites forced to live out new pathways toward restoration. Brett retrieves the prophetic voice of Scripture and applies it to our contemporary world, addressing current justice issues in a relevant, constructive, compelling manner. (shrink)

This paper offers a new way to make sense of disagreement expansion from a polylogical perspective by incorporating various places in addition to players and positions into the analysis. The concepts build on prior implicit ideas about disagreement space by suggesting how to more fully account for argumentative context, and its construction, in large-scale complex controversies. As a basis for our polylogical analysis, we use a New York Times news story reporting on an oil train explosion—a significant point in the (...) broader controversy over producing oil and gas via hydraulic fracturing.

A specific issue for argumentation theory is whether information and communication technologies play any role in governing argument — that is, as parties engage in practical activities across space and time via ICTs, does technology matter for the interplay of argumentative content and process in managing disagreement? The case made here is that technologies do matter because they are not merely conduits of communication but have a role in the pragmatics of communication and argumentation. In particular, ICTs should be recognized (...) as communication-information services that are delegated degrees of responsibility for managing disagreements arising from practical activities. These services are organized around practical theories for designing disagreement space. However, recognizing this relationship between argument and technology requires accounting for procedures, techniques, or rules and speech acts that are not argumentative propositions in any strict sense but that are consequential for what becomes argumentation in any setting. An account about designing disagreement space, grounded in Jackson and Jacobs’s theory of Disagreement Management, is put forward to address these issues while more generally contributing to understanding argument in context.

It is argued here that large-scale organization and networked computing enable new divisions of communicative work aimed at shaping the content, direction, and outcomes of societal conversations. The challenge for argumentation theory and practice lies in attending to these new divisions of communicative work in constituting contemporary argumentative realities. Goffman’s conceptualization of participation frameworks and production formats are applied to articulate the communicative work of organizations afforded by networked computing that invents and innovates argument in all of its senses—as product, (...) process, and procedure. Communicative work, however, may be scaffolding argumentative contexts and practices that are quite different than what has constituted past argumentative realities. The computerization of argument happens as organizations invent and innovate argument practice relative to the demands and opportunities of interorganizational communication. The cases and examples examined here suggest that argument practice is evolving around the logic of conversation and the principle of personalization. The analysis challenges argumentation theory to seriously engage with the construction of communicative contexts and the realization of ideas about disagreement management in organizational practice and information infrastructures. Directions for integrating insights from a design perspective on argument with insights from organizational and information systems theory are proposed for coming to terms with an era of large-scale organization and computerization, in particular the evolution of argument practice, the inscription of argument in the built environment, and the absorption of socio-cultural argument practices by organizations and computation.

Everyone wants to be virtuous, but recent psychological investigations suggest that this may not be possible. Mark Alfano challenges this theory and asks, not whether character is empirically adequate, but what characters human beings could have and develop. Although psychology suggests that most people do not have robust character traits such as courage, honesty and open-mindedness, Alfano argues that we have reason to attribute these virtues to people because such attributions function as self-fulfilling prophecies - children become more studious (...) if they are told that they are hard-working and adults become more generous if they are told that they are generous. He argues that we should think of virtue and character as social constructs: there is no such thing as virtue without social reinforcement. His original and provocative book will interest a wide range of readers in contemporary ethics, epistemology, moral psychology and empirically informed philosophy. (shrink)

Like much in this book, the title and dust jacket illustration are clever. The first evokes Hume's remark in the Treatise that ‘Reason is, and ought only to be the slave of the passions.’ The second, which represents a cross between a dance-step and a clinch, links up with the title and anticipates an example used throughout the book to support its central claims: that Ronnie, unlike Bradley, has a reason to go to a party – namely, that there will (...) be dancing at the party – because Ronnie, unlike Bradley, loves dancing. So, the explanation of why Ronnie's and Bradley's reasons differ lies in their respective psychologies.Schroeder argues for a version of the Humean Theory of Reasons he calls Hypotheticalism, which says that every reason is explained by a desire in the same way as Ronnie's is. Schroeder argues that on almost every count, Hypotheticalism is as good as, or preferable to, the Humean and non-Humean alternatives; and he defends it against an array of objections. For example, he explains that while Hypotheticalism claims that ‘desires have to serve in the explanation of every reason because desires are part of the correct analysis of reasons’, it does not claim that a desire that explains a reason is part of that reason: rather it is a background condition for it. This, Schroeder argues, allows him to rebut a variety of objections that depend on conflating reasons with their background conditions. Other …. (shrink)

In this largely antimetaphysical treatment of free will and determinism, Mark Balaguer argues that the philosophical problem of free will boils down to an open scientific question about the causal histories of certain kinds of neural events. In the course of his argument, Balaguer provides a naturalistic defense of the libertarian view of free will. The metaphysical component of the problem of free will, Balaguer argues, essentially boils down to the question of whether humans possess libertarian free will. Furthermore, (...) he argues that, contrary to the traditional wisdom, the libertarian question reduces to a question about indeterminacy--in particular, to a straightforward empirical question about whether certain neural events in our heads are causally undetermined in a certain specific way; in other words, Balaguer argues that the right kind of indeterminacy would bring with it all of the other requirements for libertarian free will. Finally, he argues that because there is no good evidence as to whether or not the relevant neural events are undetermined in the way that's required, the question of whether human beings possess libertarian free will is a wide-open empirical question.

YouTube has been implicated in the transformation of users into extremists and conspiracy theorists. The alleged mechanism for this radicalizing process is YouTube’s recommender system, which is optimized to amplify and promote clips that users are likely to watch through to the end. YouTube optimizes for watch-through for economic reasons: people who watch a video through to the end are likely to then watch the next recommended video as well, which means that more advertisements can be served to them. This (...) is a seemingly innocuous design choice, but it has a troubling side-effect. Critics of YouTube have alleged that the recommender system tends to recommend extremist content and conspiracy theories, as such videos are especially likely to capture and keep users’ attention. To date, the problem of radicalization via the YouTube recommender system has been a matter of speculation. The current study represents the first systematic, pre-registered attempt to establish whether and to what extent the recommender system tends to promote such content. We begin by contextualizing our study in the framework of technological seduction. Next, we explain our methodology. After that, we present our results, which are consistent with the radicalization hypothesis. Finally, we discuss our findings, as well as directions for future research and recommendations for users, industry, and policy-makers. (shrink)

The last few decades have witnessed the birth and growth of both virtue epistemology and the situationist challenge to virtue ethics. It seems only natural that eventually we would see the situationist challenge to virtue epistemology. This article articulates one aspect of that new challenge by spelling out an argument against the responsibilist brand of virtue epistemology. The trouble can be framed as an inconsistent triad: many people know quite a bit; knowledge is true belief acquired and retained through the (...) exercise of intellectual virtue; most people do not possess the intellectual virtues countenanced by responsibilism. Non‐skepticism is a Moorean platitude we should aim to preserve at most if not all costs. I muster evidence from cognitive and social psychology to argue for epistemic situationism. If my argument is correct, responsibilism must be revised or rejected, and reliabilists should avoid incorporating responsibilist components into their theories. (shrink)

Many scholars agree that the Internet plays a pivotal role in self-radicalization, which can lead to behaviours ranging from lone-wolf terrorism to participation in white nationalist rallies to mundane bigotry and voting for extremist candidates. However, the mechanisms by which the Internet facilitates self-radicalization are disputed; some fault the individuals who end up self-radicalized, while others lay the blame on the technology itself. In this paper, we explore the role played by technological design decisions in online self-radicalization in its myriad (...) guises, encompassing extreme as well as more mundane forms. We begin by characterizing the phenomenon of technological seduction. Next, we distinguish between top-down seduction and bottom-up seduction. We then situate both forms of technological seduction within the theoretical model of dynamical systems theory. We conclude by articulating strategies for combatting online self-radicalization.

References to energy of the universe have focussed upon the matter contribution, whereas the conservation laws must include a gravitational contribution as well. The conservation laws as applied to FRW cosmologies suggest a zero total energy irrespective of the spatial curvature when the value of the cosmological constant is taken to be zero. This result provides a useful constraint on models of the early universe and lends support to currently studied theories of the universe arising as a quantum fluctuation of (...) the vacuum.

Recent work in experimental philosophy has shown that people are more likely to attribute intentionality, knowledge, and other psychological properties to someone who causes a bad side effect than to someone who causes a good one. We argue that all of these asymmetries can be explained in terms of a single underlying asymmetry involving belief attribution because the belief that one’s action would result in a certain side effect is a necessary component of each of the psychological attitudes in question. (...) We argue further that this belief-attribution asymmetry is rational because it mirrors a belief-formation asymmetry, and that thebelief-formation asymmetry is also rational because it is more useful to form some beliefs than others.

Moral philosophers, legal theorists, and psychologists who study moral judgment are remarkably agreed in prescribing how to blame people. A blameworthy act occurs when an actor intentionally, negligently or recklessly causes foreseen, or foreseeable, harmful consequences without any compelling mitigating or extenuating circumstances. This simple formulation conveniently forestalls intricacies about how to construe concepts such as will, causation, foresight, and mitigation, but putting that aside for the moment, it seems fair to say that blame “professionals” share compatible conceptions of how (...) to make fair and rational blame ascriptions. Blame “amateurs,” on the other hand, sometimes stretch these rational prescriptions for blame beyond the breaking point. Numerous psychological studies on blame and responsibility, as well as the perplexing outcomes of high-profile criminal and civil trials, demonstrate that everyday blamers are capable of violating virtually every rational prescription that moral philosophers, legal scholars, and rational decision theorists hold dear.

When Thomas Nagel originally coined the expression “moral luck,” he used the term “luck” to mean lack of control. This use was a matter of stipulation, as Nagel’s target had little to do with luck itself, but the question of how control is related to moral responsibility. Since then, we have seen several analyses of the concept of luck itself, and recent contributors to the moral luck literature have often assumed that any serious contribution to the moral luck debate must (...) begin with a robust concept of luck simpliciter. I argue here that this assumption is a mistake, on the basis of three reasons: the issue was originally conceived as an issue about responsibility and control, analyses of luck tend to distort and needlessly to complicate what is at issue when shoehorned into the moral luck debate, and these analyses have very little (if anything) to contribute to the discussion.

Virtue ethics has been challenged on empirical grounds by philosophical interpreters of situationist social psychology. Challenges are necessarily challenges to something or other, so it’s only possible to understand the situationist challenge to virtue ethics if we have an antecedent grasp on virtue ethics itself. To this end, I first identify the non-negotiable “hard core” of virtue ethics with the conjunction of nine claims, arguing that virtue ethics does make substantive empirical assumptions about human conduct. Next, I rearticulate the situationist (...) challenge in light of these nine claims. I then turn to a discussion of specifications of several responses typically made by defenders of virtue ethics against the situationist challenge, arguing that most of them either are unsound or give up one of the elements in the hard core. A few, however, survive this criticism, and so I conclude by suggesting ways in which the situationist challenge might be not so much resisted as co-opted. Situational influences can be used to help people simulate virtue, a phenomenon I call factitious virtue. (shrink)

This book provides a rich, systematic, and accessible introduction to moral psychology, aimed at undergraduate philosophy and psychology majors. There are eight chapters, in addition to a short introduction, prospective conclusion, and extensive bibliography. The recipe for each chapter will be: a) to introduce a philosophical topic (e.g., altruism, virtue, preferences, rules) and some prominent positions on it, without assuming prior acquaintance on the part of the reader b) to canvass and explain the relevance of a particular domain of empirical (...) inquiry (e.g., evolutionary psychology, behavioral economics, neuroscience) to the topic c) to argue for some tentative conclusions about the topic d) to suggest further avenues for conceptual and empirical research The guiding theme of the book is that moral philosophy without psychological content is empty, whereas psychological investigation without philosophical insight is blind. Thus, I advocate a holistic approach that pictures moral psychology as a project of collaborative inquiry into the descriptive and normative aspects of the human condition. Ideally, students will come away from (a course built around) the book with the sense that, though philosophy may not be the queen of the sciences, its role is not merely to interpret scientific results.

Because obituaries are succinct and explicitly intended to summarize their subjects’ lives, they may be expected to include only the features that the author finds most salient but also to signal to others in the community the socially-recognized aspects of the deceased’s character. We begin by reviewing studies 1 and 2, in which obituaries were carefully read and labeled. We then report study 3, which further develops these results with a semi-automated, large-scale semantic analysis of several thousand obituaries. Geography, gender, (...) and elite status all turn out to be associated with the virtues and values associated with the deceased. (shrink)

The turn to descriptive studies of ethics is inspired by the sense that our ethical theorizing needs to engage ethnography, history, and literature in order to address the full complexity of ethical life. This article examines four books that describe the cultivation of virtue in diverse cultural contexts, two concerning early China and two concerning Islam in recent years. All four emphasize the significance of embodiment, and they attend to the complex ways in which choice and agency interact with the (...) authority of tradition. In considering these books, this article examines the relations between our academic claims concerning the self and ethics, conceptual or theoretical claims made in the elite writings of traditions, and the lived experiences of the people we study. The conclusion turns to our methodological foundations for studying these topics both comparatively and constructively. (shrink)

In this paper, I describe some of what I take to be the more interesting features of friendship, then explore the extent to which other virtues can be reconstructed as sharing those features. I use trustworthiness as my example throughout, but I think that other virtues such as generosity & gratitude, pride & respect, and the producer’s & consumer’s sense of humor can also be analyzed with this model. The aim of the paper is not to demonstrate that all moral (...) virtues are exactly like friendship in all important respects, but rather to articulate a fruitful model in which to explore the virtues. Section 2 explores the relational nature of friendship, drawing on Aristotle’s discussion of friendship in the Nicomachean Ethics. Section 3 catalogues four motivations for taking seriously the friendship model of virtue. Section 4 applies the friendship model in depth to the virtue of trustworthiness. (shrink)

This book is an examination of the nature of economic explanation. The opening chapters introduce current thinking in the philosophy of science and review the literature on methodology. Professor Blaug then turns to the troublesome question of the logical status of welfare economics, giving the reader an understanding of the outstanding issues in the methodology of economics. This is followed by a series of case studies of leading economic controversies, which shows how controversies in economics may be illuminated by paying (...) attention to questions of methodology. A final chapter draws the strands together and gives the author's view of what is wrong with modern economics. This book is a revised and updated edition of a classic work on the methodology of economics, in which Professor Blaug develops his discussion of the latest developments in macroeconomics, general equilibrium theory and international trade theory. A new section on the rationality postulate is also added. (shrink)

Experimental moral philosophy emerged as a methodology in the last decade of the twentieth century, as a branch of the larger experimental philosophy (X-Phi) approach. Experimental moral philosophy is the empirical study of moral intuitions, judgments, and behaviors. Like other forms of experimental philosophy, it involves gathering data using experimental methods and using these data to substantiate, undermine, or revise philosophical theories. In this case, the theories in question concern the nature of moral reasoning and judgment; the extent and sources (...) of moral obligations; the nature of a good person and a good life; even the scope and nature of moral theory itself. This entry begins with a brief look at the historical uses of empirical data in moral theory and goes on to ask what, if anything, is distinctive about experimental moral philosophy—how should we distinguish it from related work in empirical moral psychology? After discussing some strategies for answering this question, the entry examines two of the main projects within experimental moral philosophy, and then discusses some of the most prominent areas of research within the field. As we will see, in some cases experimental moral philosophy has opened up new avenues of investigation, while in other cases it has influenced longstanding debates within moral theory. (shrink)
