Physical theories often characterize their observables with real number precision. Many non-fundamental theories do so needlessly: they are more precise than they need to be to capture the physical matters of fact about their observables. A natural expectation is that a truly fundamental theory will require its full precision in order to exhaustively capture all of the fundamental physical matters of fact. I argue against this expectation and I show that we do not have good reason to expect that the (...) standard of precision set by successful theories, or even by a truly fundamental theory, will match the granularity of the physical facts.

Approaches to the interpretation of physical theories provide accounts of how physical meaning accrues to the mathematical structure of a theory. According to many standard approaches to interpretation, meaning relations are captured by maps from the mathematical structure of the theory to statements expressing its empirical content. In this article I argue that while such accounts adequately address meaning relations when exact models are available or perturbation theory converges, they do not fare as well for models that give rise to (...) divergent perturbative expansions. Since truncations of divergent perturbative expansions often play a critical role in establishing the empirical adequacy of a theory, this is a serious deficiency. I show how to augment state-space semantics, a view developed by Beth and van Fraassen, to capture perturbatively evaluated observables even in cases where perturbation theory is divergent. This new semantics establishes a sense in which the calculations that underwrite the empirical adequacy of a theory are both meaningful and true, but requires departure from the assumption that physical meaning is captured entirely by the exact models of a theory.

Haag's theorem has been interpreted as establishing that quantum field theory cannot consistently represent interacting fields. Earman and Fraser have clarified how it is possible to give mathematically consistent calculations in scattering theory despite the theorem. However, their analysis does not fully address the worry raised by the result. In particular, I argue that their approach fails to be a complete explanation of why Haag's theorem does not undermine claims about the empirical adequacy of particular quantum field theories. I then (...) show that such empirical adequacy claims are protected from Haag's result by the techniques that are required to obtain theoretical predictions for realistic experimental observables. I conclude by showing how Haag's theorem is illustrative of a general tension between the foundational significance of results that can be obtained in perturbation theory and non-perturbative characterizations of the content of quantum field theory.

Individuals differ greatly in their ability to learn and navigate through environments. One potential source of this variation is “directional sense” or the ability to identify, maintain, and compare allocentric headings. Allocentric headings are facing directions that are fixed to the external environment, such as cardinal directions. Measures of the ability to identify and compare allocentric headings, using photographs of familiar environments, have shown significant individual and strategy differences; however, the neural basis of these differences is unclear. Forty-five college students, (...) who were highly familiar with a campus environment and ranged in self-reported sense-of-direction, underwent fMRI scans while they completed the Relative Heading task, in which they had to indicate the direction of a series of photographs of recognizable campus buildings (i.e., “target headings”) with respect to initial “orienting headings”. Large individual differences were found in accuracy and correct decision latencies, with gender, self-reported sense-of-direction, and familiarity with campus buildings all predicting task performance. Using linear mixed models, the directional relationships between headings and the experiment location also impacted performance. Structural scans revealed that lateral orbitofrontal and superior parietal volume were related to task accuracy and decision latency, respectively. Bilateral hippocampus and right presubiculum volume were related to self-reported sense-of-direction. Meanwhile, functional results revealed clusters within the superior parietal lobule, supramarginal gyrus, superior frontal gyrus, lateral orbitofrontal cortex, and caudate among others in which the intensity of activation matched the linear magnitude of the difference between the orienting and target headings. While the retrosplenial cortex and hippocampus have previously been implicated in the coding of allocentric headings, this work revealed that comparing those headings additionally involved frontal and parietal regions. These results provide insights into the neural bases of the variation within human orientation abilities, and ultimately, human navigation. (shrink)

I present an original model in judgment aggregation theory that demonstrates the general impossibility of consistently describing decision-making purely at the group level. Only a type of unanimity rule can guarantee a group decision is consistent with supporting reasons, and even this possibility is limited to a small class of reasoning methods. The key innovation is that this result holds when individuals can reason in different ways, an allowance not previously considered in the literature. This generalizes judgment aggregation to subjective (...) decision situations, implying that the discursive dilemma persists without individual agreement on the logical constraints. Notably, the model mirrors the typical method of choosing political representatives, and thus suggests that no voting procedure other than unanimity rule can guarantee representation that reflects electorate opinion. Finally, I apply the results to a normative argument for unanimity rule in contract theory and juries, as well as to problems posed for deliberative democratic theory and the concept of representation.

It has long been maintained that Descartes believed animals are nothing more than complex living machines. Throughout the centuries many have criticized Descartes for holding such a doctrine, for it has been used by others to justify a total disregard for the well-being of animals. However, a trend in Cartesian scholarship suggests that Descartes’s reputation for justifying cruelty to animals is undeserved because Descartes apparently lacked confidence in the truth of his own doctrine. This paper reviews the arguments calling for (...) a revision of the standard interpretation, examines Descartes’s statements about animal intelligence and consciousness, considers his treatment of animals, and reaffirms the standard interpretation.

The representational theory of measurement provides a collection of results that specify the conditions under which an attribute admits of numerical representation. The original architects of the theory interpreted the formalism operationally and explicitly acknowledged that some aspects of their representations are conventional. There have been a number of recent efforts to reinterpret the formalism to arrive at a more metaphysically robust account of physical quantities. In this paper we argue that the conventional elements of the representations afforded by the (...) representational theory of measurement require careful scrutiny as one moves toward such an interpretation. To illustrate why, we show that there is a sense in which the very number system in which one represents a physical quantity such as mass or length is conventional. We argue that this result does not undermine the project of reinterpreting the representational theory of measurement for metaphysical purposes in general, but it does undermine a certain class of inferences about the nature of physical quantities that some have been tempted to draw.

Artificial Intelligence (AI) contributes to common goods and common harms in our everyday lives. In light of the Collingridge dilemma, information about both the actual and potential harm of AI is explored and myths about AI are dispelled. Catholic health care is then presented as being in a unique position to exert its influence to model the use of AI systems that minimizes the risk of harm and promotes human flourishing and the common good.

The mechanisms by which most receptor protein‐tyrosine kinases (RTKs) transmit signals are now well established. Binding of ligand results in the dimerization of receptor monomers followed by transphosphorylation of tyrosine residues within the cytoplasmic domains of the receptors. This tidy picture has, however, some strange characters lurking around the edges. Cases have now been identified in which RTKs lack kinase activity, but, despite being “dead” appear to have roles in signal transduction. Even stranger are the cases in which genes encoding (...) RTKs produce protein products consisting of only a portion of the kinase domain. At least one such “fractured” RTK appears to be involved in signal transduction. Here we describe how these strange molecules might function and discuss the questions associated with their evolution. BioEssays 23:69–76, 2001. © 2001 John Wiley & Sons, Inc. (shrink)

Charney's dismissal of well-established methods in behavioral genetic research is misguided. He claims that studies of heritability and genetic association depend for their validity on six assumptions, but he cites no sources to support this claim. We explain why none of the six assumptions is strictly necessary for the utility of either method of genetic analysis.

This paper analyzes individual probabilistic predictions of state outcomes in the 2008 U.S. presidential election. Employing an original survey of more than 19,000 respondents, ours is the first study of electoral forecasting to involve multiple subnational predictions and to incorporate the influence of respondents’ home states. We relate a range of demographic, political, and cognitive variables to individual accuracy and predictions, as well as to how accuracy improved over time. We find strong support for wishful thinking bias in expectations, as (...) Republicans gave higher probabilities to McCain victories and were worse at overall prediction. In addition, we find that respondents living in states with higher vote shares for Obama performed better at prediction and displayed less wishful thinking bias. We conclude by showing that suitable aggregations of our respondents’ predictions outperformed Intrade (a prediction market) and fivethirtyeight.com (a poll-based forecast) at most points in time.

This paper places Julian Schwinger's development of the Euclidean Green's function formalism for quantum field theory in historical context. It traces the techniques employed in the formalism back to Schwinger's work on waveguides during World War II, and his subsequent formulation of the Minkowski space Green's function formalism for quantum field theory in 1951. Particular attention is dedicated to understanding Schwinger's physical motivation for pursuing the Euclidean extension of this formalism in 1958.

The Catholic moral tradition has a rich foundation that applies broadly to encompass all areas of human experience. Yet, there is comparatively little in Catholic thought on the ethics of the collection and use of data, especially in healthcare. We provide here a brief overview of terminology, concepts, and applications of data in the context of healthcare, summarize relevant theological principles and themes (including the Vatican’s Rome Call for AI Ethics), and offer key questions for ethicists and data managers to (...) consider as they analyze ethical implications pertinent to data governance and data management.

_Clinical Interaction and the Analysis of Meaning_ evinces a therapeutic vitality all too rare in works of theory. Rather than fleeing from the insights of other disciplines, Dorpat and Miller discover in recent research confirmation of the possibilities of psychoanalytic treatment. In Section I, "Critique of Classical Theory," Dorpat proposes a radical revision of the notion of primary process consonant with contemporary cognitive science. Such a revised conception not only enlarges our understanding of the analytic process; it also provides analysis (...) with a conceptual language that can articulate meaningful connections with a growing body of empirical research about the development and nature of human cognition. In Section II, "Interactional Theory," Miller reverses the direction of inquiry. He begins with the literature on cognitive development and functioning, and proceeds to mine it for concepts relevant to the clinical process. He shows how a revised understanding of the operation of cognition and affect can impart new meaning to basic clinical concepts such as resistance, transference, and level of psychopathology. In Section III, "Applications and Exemplifications," Dorpat concludes this exemplary collaboration by exploring select topics from the standpoint of his and Miller's new psychoanalytic theory. At the heart of the authors' endeavor it "meaning analysis," a concept that integrates an up-to-date model of human information processing with the traditional goals of psychoanalysis. The patient approaches the clinical encounter, they argue, with cognitive-affective schemas that are the accumulatice product of his life experience to date; the manifold meanings ascribed to the clinical interaction must be understood as the product of these schemas rather than as distortions deriving from unconscious, drive-related fantasies. The therapist's goal is to make the patient's meaning-making conscious and thus available for introspection. (shrink)

ABSTRACT Certain problems in commonsense reasoning lend themselves to the use of non-standard formalisms which we call active logics. Among these are problems of objects misidentification. In this paper we describe some technical issues connected with automated inference in active logics, using particular object misidentification problems as illustrations. Control of exponential growth of inferences is a key issue. To control this growth attention is paid to a limited version of an inference rule for negative introspection. We also present some descriptive (...) statistics for comparison with earlier active-logic approaches. (shrink)

Within Luis Buñuel's classic surrealist film The Exterminating Angel is a philosophical motif which expresses, demonstrates, and develops two of Ludwig Wittgenstein's central concepts: language lays traps for the unwary that can lead to illogical thought and mind-bending quests; and any picture of the world is formed through cultural habits that cannot be rationally expressed but can be changed. This article argues that what we find in Buñuel's Angel is a “picture” that is at one level rational and habitual and (...) at another entirely absurd. These apparently rational preconceptions – the insular habits of privilege and the language that maintains it – produce a certain “aspect” which, when clung to, can entrap us. In this effort we thread a series of chance meetings into a web of encounters: of people at a dinner party, of a philosopher and a filmmaker, and perhaps most significantly, of games that form a totality of gamesmanship – a chance meeting of the game...

This book contributes to current bioethical debates by providing a critical analysis of the philosophy of human death. Bernard N. Schumacher discusses contemporary philosophical perspectives on death, creating a dialogue between phenomenology, existentialism and analytic philosophy. He also examines the ancient philosophies that have shaped our current ideas about death. His analysis focuses on three fundamental problems: the definition of human death, the knowledge of mortality and of human death as such, and the question of whether death is 'nothing' to (...) us or, on the contrary, whether it can be regarded as an absolute or relative evil. Drawing on scholarship published in four languages and from three distinct currents of thought, this volume represents a comprehensive and systematic study of the philosophy of death, one that provides a provocative basis for discussions of the bioethics of human mortality.

In athletics, coaches and athletes share a unique and important relationship. Recently Jowett and her colleagues (Jowett & Cockerill, 2003; Jowett & Meek, 2000; Jowett & Ntoumanis, 2003, 2004; Jowett & Timson-Katchis, 2005) utilized relationship research (focusing on, for example, marital, familial and workplace relationships) from conjoining fields, and in particular social and cognitive psychology, to develop and test a four-component model (4 C’s) that depicts the most influential relational and emotional components (closeness, commitment, complementarity and co-orientation) of coach-athlete relationships. (...) Proceeding from a review of the literature on human touch communication to examine research on the power of touch to exchange relational and emotional messages (Hertenstein et al., 2006), the present study explores coaches’ and athletes’ collective experiences of communicating via touch, utilizing in-depth interviews with eight college coaches and athletes. A phenomenological approach was used to gather, analyze and interpret the data, drawing on Merleau-Ponty’s (1945/1962) philosophical exploration of perception and human experience, which emphasizes the body as a means of communicating with the world. The findings indicate that touch between coaches and athletes increased at major events when emotions and tensions ran high. In addition, touch involved showing appreciation, instructing, comforting and giving attention, and affected perceptions of relationships. The findings also show that touch communication is influenced by societal factors, such as gender, relational stage, and what spectators, parents and other athletes may think. By illustrating how touch is enacted and experienced by a group of college coaches and athletes, the study represents an initial step toward understanding touch communication in the coach-athlete dyad.

The practice of freedom that is finite, realistically libertarian, and relational is vital for the wholesome development of human beings. In promoting this idea, Michael Miller challenges traditional Christian teachings that have hindered the pursuit of freedom by human beings on the basis of their humanity per se. It also provides theological, ethical, and ecclesiological insights to inspire ventures in freedom and guidance to those who are on the path of freedom.

"The work of Jacques Lacan is associated more with literature and philosophy than mainstream American psychology, due in large part to the dense language he often employs in articulating his theory - often at the expense of clinical illustration. As a result, his contributions are frequently fascinating, but their utility in the therapeutic setting can be difficult to pinpoint. Lacanian Psychotherapy aims to fill in this clinical gap by presenting theoretical discussions in clear, accessible language and applying them to several (...) chapter-length case studies, thereby demonstrating their clinical relevance. The central concern of this book is the application of Lacan’s notion that the unconscious is structured like, and by, language. This implies a peculiar manner of listening ("to the letter") and intervention, which Miller applies to a number of common clinical concerns - including case formulation, dreams, transference, and diagnosis - in the context of psychotherapy"–Provided by publisher.

One of the most powerful traditions of the Jewish fascination with language is that of the Name. Indeed, the Jewish mystical tradition would seem a two millennia long meditation on the nature of name in relation to object, and how name mediates between subject and object. Even within the tide of the 20th century's linguistic turn, the aspect most notable in - the almost entirely secular - Jewish philosophers is that of the personal name, here given pivotal importance in the (...) articulation of human relationships and dialogue. The Name of God in Jewish Thought examines the texts of Judaism pertaining to the Name of God, offering a philosophical analysis of these as a means of understanding the metaphysical role of the name generally, in terms of its relationship with identity. The book begins with the formation of rabbinic Judaism in Late Antiquity, travelling through the development of the motif into the Medieval Kabbalah, where the Name reaches its grandest and most systematic statement - and the one which has most helped to form the ideas of Jewish philosophers in the 20th and 21st Century. This investigation will highlight certain metaphysical ideas which have developed within Judaism from the Biblical sources, and which present a direct challenge to the paradigms of western philosophy. Thus a grander subtext is a criticism of the Greek metaphysics of being which the west has inherited, and which Jewish philosophers often subject to challenges of varying subtlety; it is these philosophers who often place a peculiar emphasis on the personal name, and this emphasis depends on the historical influence of the Jewish metaphysical tradition of the Name of God. Providing a comprehensive description of historical aspects of Jewish Name-Theology, this book also offers new ways of thinking about subjectivity and ontology through its original approach to the nature of the name, combining philosophy with text-critical analysis. As such, it is an essential resource for students and scholars of Jewish Studies, Philosophy and Religion. (shrink)
