Background: While religious faith remains one of the most significant features of human life, little is known about its relationship to ordinary belief at the level of the brain. Nor is it known whether religious believers and nonbelievers differ in how they evaluate statements of fact. Our lab previously has used functional neuroimaging to study belief as a general mode of cognition, and others have looked specifically at religious belief. However, no research has compared these two states of mind directly. (...) Methodology/Principal Findings: We used functional magnetic resonance imaging to measure signal changes in the brains of thirty subjects - fifteen committed Christians and fifteen nonbelievers - as they evaluated the truth and falsity of religious and nonreligious propositions. For both groups, and in both categories of stimuli, belief was associated with greater signal in the ventromedial prefrontal cortex, an area important for self-representation, emotional associations, reward, and goal-driven behavior. This region showed greater signal whether subjects believed statements about God, the Virgin Birth, etc. or statements about ordinary facts. A comparison of both stimulus categories suggests that religious thinking is more associated with brain regions that govern emotion, self-representation, and cognitive conflict, while thinking about ordinary facts is more reliant upon memory retrieval networks. Conclusions/Significance: While religious and nonreligious thinking differentially engage broad regions of the frontal, parietal, and medial temporal lobes, the difference between belief and disbelief appears to be content-independent. Our study compares religious thinking with ordinary cognition and, as such, constitutes a step toward developing a neuropsychology of religion. However, these findings may also further our understanding of how the brain accepts statements of all kinds to be valid descriptions of the world. © 2009 Harris et al. (shrink)

Our objective is to test an optimality model of human fertility that specifies the behavioral requirements for fitness maximization in order (a) to determine whether current behavior does maximize fitness and, if not, (b) to use the specific nature of the behavioral deviations from fitness maximization towards the development of models of evolved proximate mechanisms that may have maximized fitness in the past but lead to deviations under present conditions. To test the model we use data from a representative sample (...) of 7,107 men living in Albuquerque, New Mexico, between 1990 and 1993. The model we test proposes that low fertility in modern settings maximizes number of grandchildren as a result of a trade-off between parental fertility and next generation fertility. Results do not show the optimization, although the data do reveal a trade-off between parental fertility and offspring education and income.We propose that two characteristics of modern economies have led to a period of sustained fertility reduction and to a corresponding lack of association between income and fertility. The first is the direct link between costs of investment and wage rates due to the forces of supply and demand for labor in competitive economies. The second is the increasing emphasis on cumulative knowledge, skills, and technologies in the production of resources. Together they produce historically novel conditions. These two features of modern economies may interact with evolved psychological and physiological mechanisms governing fertility and parental investment to produce behavior that maximizes the economic productivity of lineages at the expense of fitness. If cognitive processes evolved to track diminishing returns to parental investment and if physiological processes evolved to regulate fertility in response to nutritional state and patterns of breast feeding, we might expect non-adaptive responses when returns from parental investment do not diminish until extremely high levels are reached. With high economic payoffs from parental investment, people have begun to exercise cognitive regulation of fertility through contraception and family planning practices. Those cognitive processes maynot have evolved to handle fitness trade-offs between fertility and parental investment. (shrink)

Background: Nurses, social workers, and medical residents are ethically mandated to engage in policy advocacy to promote the health and well-being of patients and increase access to care. Yet, no instrument exists to measure their level of engagement in policy advocacy. Research objective: To describe the development and validation of the Policy Advocacy Engagement Scale, designed to measure frontline healthcare professionals’ engagement in policy advocacy with respect to a broad range of issues, including patients’ ethical rights, quality of care, culturally (...) competent care, preventive care, affordability/accessibility of care, mental healthcare, and community-based care. Research design: Cross-sectional data were gathered to estimate the content and construct validity, internal consistency, and test–retest reliability of the Policy Advocacy Engagement Scale. Participants and context: In all, 97 nurses, 94 social workers, and 104 medical residents were recruited from eight acute-care hospitals in Los Angeles County. Ethical considerations: Informed consent was obtained via Qualtrics and covered purposes, risks and benefits; voluntary participation; confidentiality; and compensation. Institutional Review Board approval was obtained from the University of Southern California and all hospitals. Findings: Results supported the validity of the concept and the instrument. In confirmatory factor analysis, seven items loaded onto one component with indices indicating adequate model fit. A Pearson correlation coefficient of.36 supported the scale’s test–retest stability. Cronbach’s α of.93 indicated strong internal consistency. Discussion: The Policy Advocacy Engagement Scale demonstrated satisfactory psychometric properties in this initial test. Findings should be considered within the context of the study’s limitations, which include a low response rate and limited geographic scope. Conclusion: The Policy Advocacy Engagement Scale appears to be the first validated scale to measure frontline healthcare professionals’ engagement in policy advocacy. With it, researchers can analyze variations in professionals’ levels of policy advocacy engagement, understand what factors are associated with it, and remedy barriers that might exist to their provision of it.

The meaning of Lorentz contraction in special relativity and its connection with Bell’s spaceships parable is discussed. The motion of Bell’s spaceships is then compared with the accelerated motion of a rigid body. We have tried to write this in a simple form that could be used to correct students’ misconceptions due to conflicting earlier treatments.

This paper examines the role of management's earnings preannouncements on judgments about its trustworthiness by nonprofessional investors. We predict that management's preannouncement decision and the resulting direction of the earnings surprise influence investors' ethical judgments about management's trustworthiness; these judgments, in turn, are associated with investors' other investment related judgments. We test our predictions in an experiment in which MBA students make investment-related judgments under four different preannouncement strategies. Consistent with our predictions, the results of our study show that managers' (...) preannouncement decisions are significantly associated with investors' evaluations of management's trustworthiness. Specifically, holding the size of the earnings surprise constant, we find that judgments of management's trustworthiness are damaged more following a negative as opposed to a positive earnings surprise, and the release of a preannouncement compared to when management does not issue a preannouncement. Also consistent with our predictions, we find that evaluations of management's trustworthiness are significantly and positively associated with judgments of the attractiveness of the firm's equity as an investment. Based on our findings, we encourage further research to explore whether managers understand the trust implications associated with their preannouncement decisions and the extent to which this understanding influences their disclosure decisions.

Whether regarded as a perplexing object, a morally captivating force, an ineffable entity beyond language, or an inescapably embodied human practice, music has captured philosophically inclined minds since time immemorial. In turn, musicians of all stripes have called on philosophy as a source of inspiration and encouragement, and scholars of music through the ages have turned to philosophy for insight into music and into the worlds that sustain it. In this Handbook, contributors build on this legacy to conceptualize the rich (...) interactions of Western music and philosophy as a series of meeting points between two vital spheres of human activity. They draw together key debates at the intersection of music studies and philosophy, offering a field-defining overview while also forging new paths. Chapters cover a wide range of musics and philosophies, including concert, popular, jazz, and electronic musics, and both analytic and continental philosophy. (shrink)

Over the last decade, numerous interventions and techniques that aim to engender, strengthen, and expand compassion have been created, proliferating an evidence base for the benefits of compassion meditation training. However, to date, little research has been conducted to examine individual variation in the learning, beliefs, practices, and subjective experiences of compassion meditation. This mixed-method study examines changes in novice meditators’ knowledge and contemplative experiences before, during, and after taking an intensive course in CBCT®, a contemplative intervention that is increasingly (...) used for both inter- and intrapersonal flourishing. The participants in this study were Christian healthcare chaplains completing a 1-year residency in Clinical Pastoral Education who learned CBCT as part of their professional chaplaincy training curriculum. Prior to and upon completion of training, we surveyed participants to assess their beliefs about the malleability of compassion, types of engagement in compassion meditation, and perceptions of the impact of taking CBCT. We also conducted in-depth interviews with a subset of participants to gain a qualitative understanding of their subjective experiences of learning and practicing compassion meditation, a key component of CBCT. We found that participants reported increases in the extent to which they believed compassion to be malleable after studying CBCT. We also found high levels of variability of individual ways of practicing and considered the implications of this for the study of contemplative learning processes. This multi-methodological approach yielded novel insights into how compassion practice and compassion-related outcomes interrelate, insights that can inform the basic scientific understanding of the experience of learning and enacting compassion meditation as a means of strengthening compassion itself.

A point charge accelerating under the influence of an external force emits electromagnetic radiation that reduces the increase in its mechanical energy. This causes a reduction in the particle's acceleration. We derive the decrease in acceleration due to radiation reaction for a particle accelerating parallel to its velocity, and show that it has a negligible effect.

We estimate the effect on business start-ups of a program that significantly speeds up firm registration procedures. The program was implemented in Mexico in different municipalities at different dates. Our estimates suggest that new start-ups increased by about 4% in eligible industries, and we present evidence that this is a causal effect. Most of the effect is temporary, concentrated in the first 10 months after implementation. The effect is robust to several specifications of the benchmark control group time trends. We (...) find that the program was more effective in municipalities with less corruption and cheaper additional procedures. (shrink)

I first show why Davidson was wrong to maintain that there is no such thing as metaphorical meaning, that which paraphrases strive to capture. I then sketch a conception of metaphors as utterances in contexts, and suggest how such utterances can acquire metaphorical meanings despite there being no semantic rules for the projection of such meanings. I next urge the essentiality of a metaphor's verbal formulation to its being the metaphor it is, and I conclude with some reflections on common (...) and uncommon metaphors, and on the difficulty of finding strings of words resistant to metaphorical construal.

This is a long-awaited reissue of Jerrold Levinson's 1990 book which gathers together the writings that made him a leading figure in contemporary aesthetics. These highly influential essays are essential reading for debates on the definition of art, the ontology of art, emotional response to art, expression in art, and the nature of art forms.

In "Literal Meaning," John Searle claims to refute the view that sentences of a natural language have a meaning independent of the social contexts in which their utterances occur. The present paper is a reply on behalf of this view. In the first section, I show that the issue is not a parochial dispute within a narrow area of the philosophy of language, of interest only to specialists in the area, but is at the heart of a wide range of (...) important philosophical problems, those on which the recent linguistic turn in philosophy has properly taken a grammatical perspective. In the second section, I reply to Searle's criticisms of the view. (shrink)

In the nearly one hundred years that have elapsed since Freud’s publication of his pioneering work with “Little Hans,” psychoanalysis has transformed not only our clinical work with children, but has immeasurably enriched our understanding of normal child and adolescent development as well as developmental deviations and derailments. We have gradually come to understand childhood and adolescence as a complex tapestry of developmental themes, conflicts, and crises; sometimes discontinuous or discrete, at other times, harmonious and integrated, yet always occurring within (...) a transactional matrix of environmental influences and internal experience. In this transdisciplinary anthology, eight authors explore the changing terrain of child and adolescent psychoanalysis and psychoanalytic therapy. The contributions, which reflect theoretical and clinical heterogeneity, are both innovative and varied, and range from the highly abstract and theoretical to those that consider very specific dimensions of clinical process. Collectively, they make a compelling case for the continued relevance of psychoanalytic ideas in the treatment of children and adolescents. With insightful contributions by expert psychoanalysts, clinical social workers, and clinical psychologists, Psychoanalytic Approaches to the Treatment of Children and Adolescents: Tradition and Transformation is essential reading for child and adolescent therapists. Psychoanalytic Approaches to the Treatment of Children and Adolescents will increase your knowledge of: the function of play in normal development--and within the treatment relationship psychoanalytic theories and research investigations linking early object loss to depression the nature of adolescent depression the theoretical and clinical dimensions of a two-systems approach to understanding psychopathology and the clinical process the dynamic meaning and clinical management of drug and alcohol abuse, promiscuity, eating disorders, violence, and other self-destructive behaviors the complexities of treating children with neuropsychological deficits.

[Derek Matravers] Jerrold Levinson maintains that he is a realist about aesthetic properties. This paper considers his positive arguments for such a view. An argument from Roger Scruton, that aesthetic realism would entail the absurd claim that many aesthetic predicates were ambiguous, is also considered and it is argued that Levinson is in no worse position with respect to this argument than anyone else. However, Levinson cannot account for the phenomenon of aesthetic autonomy: namely, that we cannot be put (...) in a position to make an aesthetic judgement by testimony alone. Finally, Levinson's views on the ontology of aesthetic properties are considered and found wanting. /// [Jerrold Levinson] Being an aesthetic realist is hard work. Derek Matravers has raised a number of concerns for the brand of aesthetic realism that I have defended in the past, and that I continue to defend, albeit with modification. Much turns on the nature of aesthetic properties, and on the reasons for acknowledging their existence. I here try to provide further illumination on both scores, suggesting in particular that many aesthetic properties can be viewed as manifest higher-order ways of appearing. Toward the end of my discussion the question of whether or not aesthetic properties are response-dependent is addressed, and I offer the tentative conclusion that some are, and some are not.

Chomsky's criticism of Bloomfieldian structuralism's conception of linguistic reality applies equally to his own conception of linguistic reality. There are too many sentences in a natural language for them to have either concrete acoustic reality or concrete psychological or neural reality. Sentences have to be types, which, by Peirce's generally accepted definition, means that they are abstract objects. Given that sentences are abstract objects, Chomsky's generativism as well as his psychologism have to be given up. Langendoen and Postal's argument in (...) The Vastness of Natural Languages to show that there are more than denumerably many sentences is flawed. But, with the view that sentences are abstract objects, the flaws can be corrected. Once psychologism and generativism are abandoned, the revolution against Bloomfieldian structuralism can be brought to completion and linguistics can be put on a sound philosophical basis. (shrink)

J. L. Austin famously thought that facts about the circumstances in which it is ordinarily appropriate and reasonable to make claims to knowledge have a great bearing on the propriety of a philosophical account of knowledge. His major criticism of the epistemological doctrines about which he wrote was precisely that they lacked fidelity to our ordinary linguistic practices. In The Significance of Philosophical Scepticism, Barry Stroud argues that Austin was misguided: it is one thing for it to be inappropriate under (...) ordinary circumstances to deny that someone knows that P, another thing for it to be true that she knows that P. Thus, to the philosophical enterprise of determining which knowledge attributions are true, Austin’s form of criticism is beside the point. I argue that, attractive though it may be, this response to Austin badly underestimates the force of his sort of criticism. (shrink)

Objective: To examine changes in patients’ desired control of the deep brain stimulator and perception of global life control throughout DBS.Methods: A consecutive cohort of 52 patients with Parkinson’s disease was recruited to participate in a prospective longitudinal study over three assessment points. Semi-structured interviews assessing participants’ desire for stimulation control and perception of global control were conducted at all three points. Qualitative data were coded using content analysis. Visual analog scales were embedded in the interviews to quantify participants’ perceptions (...) of control over time.Results: Participants reported significant increases in their perception of global control over time and significant declines in their desired control of the stimulation. These changes were unrelated to improvements in motor symptoms. Improvements in global control were negatively correlated with a decline in desired stimulation control. Qualitative data indicate that participants have changed, nuanced levels of desired control over their stimulators. Increased global life control following DBS may be attributed to increased control over PD symptoms, increased ability to engage in valued activities, and increased overall self-regulation, while other domains related to global control remained unaffected by DBS.Conclusions: There are few empirical data documenting patients’ desire for stimulation control throughout neuromodulation and how stimulation control is related to other aspects of control despite the growing application of neuromodulation devices to treat a variety of disorders. Our data highlight distinctions in different types of control and have implications for the development of patient-controlled neurostimulation devices. (shrink)

Plato is the first philosopher to see courage as primarily a philosophical virtue. This innovation, the necessary link between courage and philosophy, stands in stark opposition to the traditional view linking courage with military or civic affairs. Plato makes courage so central to the life of philosophy that this fact alone sets him apart from almost every other author in the western philosophical canon. Courage of a new type, philosophical courage, emerges in his writings, a kind of courage necessary for (...) and configured to the philosophical life. ;The Introduction presents an overview of the pre-philosophical development of courage from Homer to Thucydides in order to prepare the transition to the Platonic understanding. Chapter One discusses the Laches, the most extensive Platonic text on courage. Chapter Two takes up the Protagoras, which discusses the issue of knowledge and its relation to courage. Chapter Three turns to the Republic and argues that whereas the highest civic activity is characterized by a desire for honor, whose psychological basis is thumos, the life of philosophy is essentially erotic. Thus, thumos and eros are connected respectively to two distinct types of courage and the move from thumos to eros is the key to explaining the move from courage in the conventional sense to philosophical courage. ;Philosophical courage implies faith in the abiding power of reason to shed light on how to face ignorance, evil, and injustice with the conviction that the remedy is philosophy itself. Plato's account of the life of philosophy is, in its very essence, characterized by philosophical courage as an enduring commitment to the project of showing that the good is the ruling principle of the universe. Philosophy remains, therefore, a quest and philosophical courage is the virtue needed to endure in that quest. Philosophical courage sustains the life of philosophy, the striving after wisdom, by maintaining the conviction of the ultimate goodness of such a life in the absence of complete and comprehensive knowledge. If the life of philosophy represents the highest human activity, then the type of courage associated with this life is correspondingly highest. (shrink)

Contemporary philosophy standardly accepts Frege's conceptions of sense as the determiner of reference and of analyticity as (necessary) truth in virtue of meaning. This paper argues that those conceptions are mistaken. It develops referentially autonomous notions of sense and analyticity and applies them to the semantics of natural kind terms. The arguments of Donnellan, Putnam, and Kripke concerning natural kind terms are widely taken to refute internalist and rationalist theories of meaning. This paper shows that the counter-intuitive consequences about the (...) reference of natural kind terms depend as much on Frege's conceptions of sense and analyticity as on what such theories of meaning say about the senses of natural kind terms. Rather than refuting the internalist and rationalist theories of meaning, the arguments of Donnellan, Putnam, and Kripke are best recast as refutations of their own Fregean assumptions. The paper also shows how autonomous notions of sense and analyticity enable us to reconstruct such theories, formulate an internalist/ rationalist account of semantic knowledge, and preserve Donnellan's, Putnam's, and Kripke's insights about reference.
