Objective: The dopamine hypothesis is one of the most influential theories of the neurobiological background of schizophrenia (SCZ). However, direct evidence for abnormal dopamine-related subcortical-cortical circuitry disconnectivity is still lacking. The aim of this study was therefore to test dopamine-related substantia nigra (SN)-based striato-thalamo-cortical resting-state functional connectivity (FC) in SCZ. Method: Based on our a priori hypothesis, we analyzed a large sample resting-state functional magnetic resonance imaging (fMRI) dataset from first-episode drug-naïve SCZ patients (n = 112) and healthy controls (n (...) = 82) using the SN as the seed region for an investigation of striato-thalamo-cortical FC. This was done in the standard band of slow frequency oscillations and then in its subfrequency bands (Slow4 and Slow5). Results: The analysis showed in SCZ: (1) reciprocal functional hypo-connectivity between SN and striatum, with differential patterns for Slow5 and Slow4; (2) functional hypo-connectivity between striatum and thalamus, as well as functional hyper-connectivity between thalamus and sensorimotor cortical areas, specifically in Slow4; (3) correlation of thalamo-sensorimotor functional hyper-connectivity with psychopathological symptoms. Conclusions: We demonstrate abnormal dopamine-related SN-based striato-thalamo-cortical FC in slow frequency oscillations in first-episode drug-naive SCZ. This suggests that altered dopaminergic function in the SN leads to abnormal neuronal synchronization (as indexed by FC) within subcortical-cortical circuitry, complementing the dopamine hypothesis in SCZ on the regional level of resting-state activity.

The aim of this article is to fill a certain gap in the assessment of relativism by drawing on Joseph Ratzinger’s (1927–2022) criticism of the normative transformation since Kant. During the Enlightenment, Natural Law was doubted as a cultural feature of Christianity that had no bearing on pluralist society. Consequently, this jurisprudential tradition underwent de-Hellenization and branched out in radical directions, the most decisive of which was Kant’s post-metaphysical system of natural values. Positivism and German Idealism attempted to restore (...) the unity of philosophy that Kant’s philosophy had disrupted. Yet even more influentially, in the nineteenth and twentieth centuries it was Marxism that relativized the doxological aspect of normativity by emphasizing the importance of praxis. Since philosophy became neither an exact science as Kant had conceived it to be, nor a practical programme for social justice as Marxism had promised, the Existentialists, and particularly Sartre, advocated a more radical philosophy of freedom. Ratzinger argues that despite the nuances of post-Kantian philosophy, Positivism, Existentialism, and Marxism failed to comprehend the human condition and that the positivist method resulted in an overwhelming relativism that has reduced normativity to a matter of correct procedures rather than regarding it as the foundation of the inviolable dignity of the human being.

In this dissertation we discuss infinite regress arguments from both a historical and a logical perspective. Throughout we deal with arguments drawn from various areas of philosophy. ;We first consider the regress generating portion of the argument. We find two main ways in which infinite regresses can be developed. The first generates a regress by defining a relation that holds between objects of some kind. An example of such a regress is the causal regress used in some versions of the (...) Cosmological Argument. The second sort of regress is generated by defining a certain procedure that can be repeated indefinitely many times. This will often be a procedure of analysis or of explanation. ;We then argue that for purposes of discussing regressive viciousness it is helpful to divide regresses into two main types. One type raises primarily epistemological issues. In this class we find the regress of justification often used in foundational arguments in epistemology. We also discuss certain arguments that treat theories of predication as attempts to explain predication. Our other class contains those regresses that raise primarily metaphysical problems. This class includes the causal regress as well as those arguments concerned with predication as an ontological problem. ;We agree with some philosophers that one problem that arises in the case of vicious regression is circularity. We show how this problem can be generalized to include other apparently non-circular regresses. The other main problem in epistemological regresses arises as a result of certain conditions that are placed on the relation involved. We look in detail at the epistemological justification regress to illustrate this last point. ;With respect to metaphysical regresses we again find several types of viciousness arguments. One problem is whether the infinite collection required for the regress is even possible. Another problem is whether an infinite number of events can occur in a finite time. These we deal with only briefly. The main difficulty with these regresses, considered as regresses and not just as infinite sets, again turns out to be certain conditions built into the relation involved. We focus on some arguments about causal regression to illustrate this point. ;Finally, we find no absolutely general conditions for regressive viciousness. There is, however, a certain limited range of ways in which a regress may be vicious. We make these ways explicit. (shrink)

Timothy J. Golden presents an existential, phenomenological, and political interpretation of Douglass's use of narrative. Reading Douglass with Kierkegaard, Kafka, Kant, and Levinas, Golden argues that analytic theism is an inauthentic preoccupation with knowledge at the expense of a concrete moral sensibility that Douglass's narrative provides.

James Baldwin writes that "I underwent, during the summer that I became fourteen, a prolonged religious crisis."1 Baldwin dealt with this crisis in his literary works through the strategic use of Christian theological themes and imagery to make compelling critiques of bourgeois cultural and Christian values. So "prolonged" was his "religious crisis" that Christian theological themes permeate Baldwin's immense literary corpus.2 Baldwin thus both was influenced by Christianity and critiqued it in his works. Considering these two points, I think it (...) appropriate to begin this essay with a biblical reference to the Christian narrative of the "fall" of humanity. I choose this biblical starting point not only because of .. (shrink)

Recent studies have demonstrated neural overlap between resting state activity and self-referential processing. This “rest-self” overlap occurs especially in anterior cortical midline structures like the perigenual anterior cingulate cortex (PACC). However, the exact neurotemporal and biochemical mechanisms remain to be identified. Therefore, we conducted a combined electroencephalography (EEG)-magnetic resonance spectroscopy (MRS) study. EEG focused on pre-stimulus (e.g., prior to stimulus presentation or perception) power changes to assess the degree to which those changes can predict subjects’ perception (and judgment) of subsequent (...) stimuli as high or low self-related. MRS measured resting state concentration of glutamate, focusing on PACC. High pre-stimulus (e.g., prior to stimulus presentation or perception) alpha power significantly correlated with both perception of stimuli judged to be highly self-related and with resting state glutamate concentrations in the PACC. In sum, our results show (i) pre-stimulus (e.g., prior to stimulus presentation or perception) alpha power and resting state glutamate concentration to mediate rest-self overlap that (ii) dispose or incline subjects to assign high degrees of self-relatedness to perceptual stimuli.

Inducing the rubber hand illusion (RHI) requires that participants look at an imitation hand while it is stroked in synchrony with their occluded biological hand. Previous explanations of the RHI have emphasized multisensory integration, and excluded higher cognitive functions. We investigated the relationship between the RHI and higher cognitive functions by experimentally testing task switch (as measured by switch cost) and mind wandering (as measured by SART score); we also included a questionnaire for attentional control that comprises two subscales, attention-shift (...) and attention-focus. To assess experience of RHI, the Botvinick and Cohen (1998) questionnaire was used and illusion onset time was recorded. Our results indicate that rapidity of onset reliably indicates illusion strength. Regression analysis revealed that participants evincing less switch cost and higher attention-shift scores had faster RHI onset times, and that those with higher attention-shift scores experienced the RHI more vividly. These results suggest that the multi-sensory hypothesis is not sufficient to explain the illusion: higher cognitive functions should be taken into account when explaining variation in the experience of ownership for the rubber hand.

In today’s world, on the one hand, the traditional networks of civic solidarity face an increasing number of challenges to overcome in the context of the politically uncontrolled economic modernization. On the other hand, the mere fact that we have become neighbours by virtue of globalization does not make us automatically brothers. At stake is the question of solidarity; civic cooperation in the today specific situation. In order to get a glimpse of the problem, this article attempts to examine some (...) outlines of the current situation of global market economy as it is understood by Joseph Ratzinger. It is an important sign of our times that demands pre-political morality from societies across the world so as to bring about an authentic cooperation. (shrink)

For half a century the idea of rational thought has been challenged by discoveries that call into question some of its foundations. How we actually think seems to be at odds with descriptive and prescriptive models that once held sway in the development of modern science and scholarship. One response to these challenges has been a loss of nerve. Another—the one on display in Rationality: Contexts and Constraints—is an active attempt to revise those models, so as to enhance their compatibility (...) with new discoveries, in a maximally coherent and inclusive way. Rationality: Contexts and Constraints is an inter-disciplinary reappraisal of the nature of rationality. In method it is pluralistic, drawing upon the analytic approaches of philosophy, linguistics, neuroscience, and more. These methods guide exploration of the intersection between hoary scholarship and cutting-edge philosophical or scientific research. In this way, Rationality: Contexts and Constraints contributes to development of a suitably revised, comprehensive understanding of rationality, one that befits the 21st century, one that is adequately informed by recent investigations of science, pathology, non-human thought, emotion, and even enigmatic Chinese texts that might previously have seemed to be expressions of irrationalism. • Addresses recent challenges and Identifies a direction for future research on rationality • Investigates the relationship between rationality and mental disorders such as delusion and depression • Assesses reasoning in artificial intelligence and nonhuman animals • Reflects on ancient Chinese Philosophy and possible cultural differences in human psychology • Employs philosophical reflection along with linguistic, probabilistic, and logical techniques -/- .

Most mental disorders affect only a small segment of the population. On the reasonable assumption that minds or brains are prone to occasional malfunction, these disorders do not seem to pose distinctive explanatory problems. Depression, however, because it is so prevalent and costly, poses a conundrum that some try to explain by characterizing it as an adaptation—a trait that exists because it performed fitness-enhancing functions in ancestral populations. Heretofore, proposed evolutionary explanations of depression did not focus on thought processes; instead, (...) they emphasized that it facilitates navigation of adverse social circumstances or promotes immune response to infectious agents. According to a new hypothesis, the “analytical rumination hypothesis” (ARH), however, depression’s crucial adaptive trait is rumination—negative, intrusive thought. ARH holds that, (i) social dilemmas trigger depressed mood; (ii) depressed mood induces changes in body systems that facilitate ruminative analysis aimed at solving dilemmas; and, (iii) depressive rumination is a fitness-enhancing trait that was selected for in evolutionary time. Jointly, (i)~(iii) imply that we should not think of rumination as a disorder; instead, it is a trade-off, an eminently rational one. In the same way that fever solves a problem—coordination of the immune system in response to infection—so too does depressive rumination solve a problem, a social dilemma, albeit at the cost of inducing anhedonia and other maladies. But they argue that the cost is worthwhile, something that should be endured “until the problem is solved.” First, we argue that there are two distinct types of rumination, brooding and pondering; the former is associated with a disposition for depression, not the latter. But only the latter has the problem-solving capabilities that ARH requires. Second, recent brain imaging studies of depression reveal resting state hypoactivity in lateral regions and hyperactivity in paralimbic regions; this asymmetric pattern correlates with heightened levels of brooding, self-focused rumination. In other words, on the personal level, patients are trapped within self, isolated from the external world and suffused with negative affect; on the subpersonal level, this pattern is reflected by an asymmetric pattern of lateral vs. paralimbic resting state activity. Third, we proceed to conjecture that rational responses (e.g., pondering) to social dilemmas are those that strike a balance between internal and external considerations in the process of belief formation. Fourth, because the asymmetric resting state activity blocks those who suffer with depression from accessing and processing potentially positive stimuli from the external world, the capacity for rational, analytic response—hence, problem-solving—is constrained. Fifth, it follows that, although there might be conditions for which suffering should be endured rather than pharmacologically alleviated, depression is not one of those. Indeed, in view of the effects of the asymmetric resting state pattern, it is unlikely that depressive rumination would have been useful even for ancestral populations. (shrink)

Time is an essential feature in bipolar disorder (BP). Manic and depressed BP patients perceive the speed of time as either too fast or too slow. The present article combines theoretical and empirical approaches to integrate phenomenological, psychological, and neuroscientific accounts of abnormal time perception in BP. Phenomenology distinguishes between perception of inner time, ie, self-time, and outer time, ie, world-time, that desynchronize or dissociate from each other in BP: inner time speed is abnormally slow (as in depression) or fast (...) (as in mania) and, by taking on the role as default-mode function, impacts and modulates the perception of outer time speed in an opposite way, ie, as too fast in depression and too slow in mania. Complementing, psychological investigation show opposite results in time perception, ie, time estimation and reproduction, in manic and depressed BP. Neuronally, time speed can be indexed by neuronal variability, ie, SD. Our own empirical data show opposite changes in manic and depressed BP (and major depressive disorder [MDD]) with abnormal SD balance, ie, SD ratio, between somatomotor and sensory networks that can be associated with inner and outer time. Taken together, our combined theoretical-empirical approach demonstrates that desynchronization or dissociation between inner and outer time in BP can be traced to opposite neuronal variability patterns in somatomotor and sensory networks. This opens the door for individualized therapeutic “normalization” of neuronal variability pattern in somatomotor and sensory networks by stimulation with TMS and/or tDCS. (shrink)

Social science, history, and philosophy have often been neglect in thinking through their fundamentally intertwined relationship. The result is often an inattention to philosophy where social science and history is concerned, or a neglect of historicity and social analysis where philosophy is concerned. Meanwhile, the place of values in research is often uneasily passed over in silence. The inattention to, and loss of, the intersection between these different disciplines and their subject matters, leaves our investigations all the more impoverished as (...) a result. In resolving these problems, it is not enough to strive for cooperation or integration, but to rethink of the nature of the disciplines themselves; their interests, purposes, and presuppositions. In this volume, contributors explore different facets of these relationships, and move beyond the problematics erected by positivism often cast in terms of value-free or value-neutral science, that is, a science obsessed with empirical data, schematic classifications, and the pursuit of law-like forms. While positivism has been subject to critique, the influence and legacy of positivism remains. It remains in the way in which we often think about science; the line drawn between the sciences and the humanities; the norms researchers should follow; what a successful explanation looks like; and the ethical, normative, and political implications of scientific research. Aimed at students and researchers of philosophy, history and the social sciences, this book is driven by a desire to revindicate questions concerning ontology and social ontology, to rethink the nature of explanation, and to resituate normativity and values within scientific, social scientific, and historical pursuits.

The following assumptions are necessary to get the contemporary problem of mental causation off the ground.

In a recent Opinion article, Sui and Humphreys [1] argue that experimental findings suggest self is ‘special’, in that self-reference serves a binding function within human cognitive economy. Contrasting their view with other functionalist positions, chiefly Dennett's [2], they deny that self is a convenient fiction and adduce findings to show that a ‘core self representation’ serves as an ‘integrative glue’ helping to bind distinct types of information as well as distinct stages of psycho- logical processing. In other words, where (...) Dennett regards self as analogous to a center of gravity, a simplification posited by observers, Sui and Humphreys regard self as a function that modulates mental processes. In practice, however, the concept of ‘self’ they employ is not unlike Dennett's. We side with Sui and Humphreys in hold- ing that self-reference modulates mental processes: reference to self during a task can bind memory to source, increase perceptual integration, and link attention to decision making, among other things. What is more, these functions are not reducible to other factors such as semantic coding, familiarity, or reward [3]. But whereas Sui and Humphreys contribute important empirical detail, the binding functions they describe are compatible with Dennett's version of functionalism, which treats self as an artifact of social process.

Review of Paul Pietroski, Causing Actions.

We posit that the weight a person assigns a moral principle is not stable between ideal, or un-contextual assessments and the weight the same moral principle is allocated when applied in a contextual dilemma. Second, we postulate that past behavior is the best predictor of future behavior or judgment. Results indicate that the importance of moral principles is dynamic and that patterned moral behavior is a significant predictor of moral judgments.

A large proportion of the total global burden of disease is caused by emergency medical conditions. Emergency care research is essential to improving emergency medicine but this research can raise some distinctive ethical challenges, especially with regard to (1) standard of care and risk–benefit assessment; (2) blurring of the roles of clinician and researcher; (3) enrolment of populations with intersecting vulnerabilities; (4) fair participant selection; (5) quality of consent; and (6) community engagement. Despite the importance of research to improve emergency (...) care in low-income and middle-income countries (LMICs) and the widely acknowledged ethical challenges, very little has been written on the ethics of emergency care research in LMICs. This paper examines the ethical and regulatory challenges to conducting emergency care research with human participants in LMICs. We outline key challenges, present potential solutions or frameworks for addressing these challenges, and identify gaps. Despite the ethical and regulatory challenges, conducting high-quality, ethical emergency care research in LMICs is possible and it is essential for global health. (shrink)

Walt Disney is largely responsible for popularizing the princess story in American culture. These stories are the centerpieces of the Disney collection and their flagship theme parks. Indeed, Cinderella's castle itself is at the heart of Disney's Magic Kingdom. The first of Disney's theme parks, the Magic Kingdom was intended to capture the magic and imagination of the Disney movies, and bring to life the settings of Disney stories. Epcot was the second of four parks built at the Walt Disney (...) World Resort location in Florida. While Liberty Square in the Magic Kingdom celebrates the independence of those who live in liberal democracies, the World Showcase at Epcot celebrates multiculturalism, and the possibility of appreciating and learning from a multitude of cultures. The chapter provides a better understanding of the philosophical tensions in Disney's theme park by taking a tour of the underlying political ideas lurking inside the Epcot and Magic Kingdom theme parks.

This essay proposes African-based ethical solutions to profound human problems and a working African model to address those problems. The model promotes sustainability through advanced agroecological and information communication technologies. The essay’s first section reviews the ethical ground of that model in the work of the Senegalese scholar, Cheikh Anta Diop. The essay’s second section examines an applied African model for translating African ethical speculation into practice. Deeply immersed in European and African ethics, Godfrey Nzamujo developed the Songhaï Centers to (...) solve the problem of rural poverty in seventeen African countries. Harnessing advanced technologies within a holistic agroecological ecosystem, Nzamujo’s villages furnish education spanning the fields of ethics, information communication technology, microbiology, international development, and mechanical, electrical, civil and biological engineering in a community-based and centered development enterprise. The essay proposes a global consortium of ecovillages based on Nzamujo’s model. The final section explores funding methods for the consortium. The conclusion contemplates a return to Africa to supplement environmental ethics that enhance life’s future on earth. (shrink)

In the final minutes of the Season 3 finale of Sons of Anarchy, it appears that Jax Teller has betrayed the MC and lived up to his nickname: “The Rat Prince.” But it is actually a set‐up to reduce the jail time for SAMCRO members. The life of freedom and camaraderie that J.T. sought when forming the MC became increasingly impossible due to the means he needed to employ to secure the club's success. The social order he founded turned out (...) to be incompatible with the very values he intended for it to foster. Jax's inward struggles offer an accurate depiction of the nuances at the heart of Machiavellian politics. He values the club beyond self‐interest, and his “public‐spiritedness” ultimately redeems his actions. Even as he engages in deceit and violence, Jax expresses sentiments closely aligned with his father's concern for the well‐being of the club and lives its members. (shrink)

In this thorough compendium, nineteen accomplished scholars explore, in some manner the values they find inherent in the world, their nature, and revelence through the thought of Frederick Ferré. These essays, informed by the insights of Ferré and coming from manifold perspectives—ethics, philosophy, theology, and environmental studies, advance an ambitious challenge to current intellectual and scholarly fashions.
