In The Platonizing Sethian Background of Plotinus's Mysticism, Zeke Mazur offers a radical reconceptualization of Plotinus with reference to Gnostic thought and praxis. A crucial element in the thought of the third-century CE philosopher Plotinus-his conception of mystical union with the One-cannot be understood solely within the conventional history of philosophy, or as the product of a unique, sui generis psychological propensity. This monograph demonstrates that Plotinus tacitly patterned his mystical ascent to the One on a type of visionary (...) ascent ritual that is first attested in Gnostic sources. These sources include the Platonizing Sethian tractates Zostrianos (NHC VIII,1) and Allogenes (NHC XI,3) of which we have Coptic translations from Nag Hammadi and whose Greek Vorlagen were known to have been read in Plotinus's school.

Le livre d’Alexandre (Zeke) Mazur [= AZM] est une édition posthume de sa thèse de doctorat soutenue en 2010 à l’Université de Chicago. Cette publication était très attendue, car, bien avant que la soutenance ait eu lieu, les vues originales d’AZM sur la mystique plotinienne attiraient l’attention des spécialistes. Dans les années 2003-2004, le jeune chercheur a fait une entrée remarquée dans le débat universitaire, en publiant un long article en deux parties : « Unio Magica, Part 1 : (...) On the M...

It is certainly the case that morality governs the interactions that take place between individuals. But what if morality exists because of these interactions? This book, first published in 2007, argues for the claim that much of the behaviour we view as 'moral' exists because acting in that way benefits each of us to the greatest extent possible, given the socially structured nature of society. Drawing upon aspects of evolutionary game theory, the theory of bounded rationality, and computational models of (...) social networks, it shows both how moral behaviour can emerge in socially structured environments, and how it can persist even when it is not typically viewed as 'rational' from a traditional economic perspective. This book also provides a theory of how moral principles and the moral sentiments play an indispensable role in effective choice, acting as 'fast and frugal heuristics' in social decision contexts.

This paper examines two questions about scientists’ search for knowledge. First, which search strategies generate discoveries effectively? Second, is it advantageous to diversify search strategies? We argue pace Weisberg and Muldoon (2009) that, on the first question, a search strategy that deliberately seeks novel research approaches need not be optimal. On the second question, we argue they have not shown epistemic reasons exist for the division of cognitive labor, identifying the errors that led to their conclusions. Furthermore, we generalize the (...) epistemic landscape model, showing that one should be skeptical about the benefits of social learning in epistemically complex environments. (shrink)

Early German Romanticism sought to respond to a comprehensive sense of spiritual crisis that characterised the late eighteenth century. The study demonstrates how the Romantics sought to bring together the new post-Kantian idealist philosophy with the inheritance of the realist Platonic-Christian tradition. With idealism they continued to champion the individual, while from Platonism they took the notion that all reality, including the self, participated in absolute being. This insight was expressed, not in the language of theology or philosophy, but through (...) aesthetics, which recognised the potentiality of all creation, including artistic creation, to disclose the divine. In explicating the religious vision of Romanticism, this study offers a new historical appreciation of the movement, and furthermore demonstrates its importance for our understanding of religion today.

Evolutionary game theoretic accounts of justice attempt to explain our willingness to follow certain principles of justice by appealing to robustness properties possessed by those principles. Skyrms (1996) offers one sketch of how such an account might go for divide-the-dollar, the simplest version of the Nash bargaining game, using the replicator dynamics of Taylor and Jonker (1978). In a recent article, D'Arms et al. (1998) criticize his account and describe a model which, they allege, undermines his theory. I sketch a (...) theory of evolutionary explanations of justice which avoids their methodological criticisms, and develop a spatial model of divide-the-dollar with more robust convergence properties than the models of Skyrms (1996) and D'Arms et al. (1998). (shrink)

This article argues that we could improve the design of research protocols by developing an awareness of and a responsiveness to the social contexts of all the actors in the research enterprise, including subjects, investigators, sponsors, and members of the community in which the research will be conducted. ?Social context? refers to the settings in which the actors are situated, including, but not limited to, their social, economic, political, cultural, and technological features. The utility of thinking about social contexts is (...) introduced and exemplified by the presentation of a hypothetical case in which one central issue is limitation of the probability of injury to subjects by selection of individuals who are not expected to live long enough for the known risks of the study to become manifest as harms. Benefits of such considerations may include enhanced subject satisfaction and cooperation, community acceptance, and improved data quality, among other desirable consequences. (shrink)

We report results of a study that utilizes a BCI to drive an interactive interface countermeasure that allows users to self-regulate sustained attention while performing an ecologically valid, long-duration business logistics task. An engagement index derived from EEG signals was used to drive the BCI while fNIRS measured hemodynamic activity for the duration of the task. Participants ( n = 30) were split into three groups (1) no countermeasures (NOCM), (2) continuous countermeasures (CCM), and (3) event synchronized, level-dependent countermeasures (ECM). (...) We hypothesized that the ability to self-regulate sustained attention through a neurofeedback mechanism would result in greater task engagement, decreased error rate and improved task performance. Data were analyzed by wavelet coherence analysis, statistical analysis, performance metrics and self-assessed cognitive workload via RAW-TLX. We found that when the BCI was used to deliver continuous interface countermeasures (CCM), task performance was moderately enhanced in terms of total 14,785 (σ = 423) and estimated missed sales 7.46% (σ = 1.76) when compared to the NOCM 14,529 (σ = 510), 9.79% (σ = 2.75), and the ECM 14,180 (σ = 875), 9.62% (σ = 4.91) groups. An “actions per minute” (APM) metric was used to determine interface interaction activity which showed that overall the CCM and ECM groups had a higher APM of 3.460 ( SE = 0.140) and 3.317 ( SE = 0.139) respectively when compared with the NOCM group 2.65 ( SE = 0.097). Statistical analysis showed a significant difference between ECM - NOCM and CCM - NOCM ( p p. (shrink)

In the course of history, many individuals have the dubious honor of being remembered primarily for an eponym of which they would disapprove. How many are aware that Joseph-Ignace Guillotin actually opposed the death penalty? Another notable case is that of Maria Agnesi, an Italian woman of privileged, but not noble, birth who excelled at mathematics and philosophy during the eighteenth century. In her treatise of 1748, Instituzioni Analitiche, she provided a comprehensive summary of the current state of knowledge concerning (...) both integral calculus and differential equations. Later in life she was elected to the Bologna Academy of Sciences and, in 1762, was consulted by the University of Turin for an opinion on the work of an up-and-coming mathematician named Joseph-Louis Lagrange.

Irenaeus, Coleridge and Gadamer all wrote about religion in distinct historical periods, however the work that each produced reflects the anthropological condition of the middle position. Furthermore, each thinker provides an opportunity for self-reflection about the motivations of faith without requiring the individual to abandon their religious belief in order to do so. In this manner they present a productive alternative to the required external views of the social sciences. The individual's position in mid-creation, his moral freedom and his historical (...) contingence all require the acceptance, commitment and trust of faith. Gnosticism, Empiricist thought and the desire to overcome historical contingency all reveal intellectual impatience in riposte to this condition. This intellectual impatience seeks the absolute without the need for faith. For Irenaeus, Coleridge and Gadamer such absolute, logocentric, complete systems end up alienating man from the reality of the incomplete condition that permeates his existence and the faith-requiring mythos that ultimate realities necessitate in order to be communicated.

This book elucidates T. F. Torrance’s reconstruction of natural theology as it appears within its intellectual context and broader Christological method. Irving argues that Torrance’s work on natural theology is an important affirmation of the priority of grace in theological method and knowledge alongside the integrity of human agency.

After over 300 years of scrutiny, the subject of Galileo continues to be pursued with unabating intensity. Dava Sobel's Galileo's Daughter points to the popular interest in the man and his legacy. The Catholic Church, understandably interested in dispelling the notion that its censure of Galileo centuries ago is proof positive that religious faith and science as well as ecclesiastical authority and free pursuit of scholarship are irreconcilable, continues to offer explanations. New books, articles and conferences probe both in breadth (...) and in depth the magnetic field charged by Galileo, science, and the Church. Galileo's analysis of the physics of motion has also received considerable attention. In particular, a great deal has been written during the past thirty years about the structure and objectives of three experiments with inclined planes. Galileo had carried them out in Padua and recorded them in his working papers. The assessments of the three experiments differ widely in points of detail, but all regard them as sophisticated, ingenious, and remarkable. This article presents a new critical study of these experiments. Its conclusion is that one of the experiments is indeed a success, but that the other two fail and are abandoned because Galileo did not have a firm enough grip on the underlying physical principles and mathematical relationships.

The General Data Protection Regulation (GDPR) of the EU confirms the protection of personal data as a fundamental human right and affords data subjects more control over the way their personal information is processed, shared, and analyzed. However, where data are processed by artificial intelligence (AI) algorithms, asserting control and providing adequate explanations is a challenge. Due to massive increases in computing power and big data processing, modern AI algorithms are too complex and opaque to be understood by most data (...) subjects. Articles 15 and 22 of the GDPR provide a modest regulatory framework for automated data processing by, among other things, mandating that data controllers inform data subjects about when it is being used, and its logic and ramifications. Nevertheless, due to the phrasing of the articles and the numerous exceptions they allow, doubts have arisen about their effectiveness. In this paper, we empirically evaluate the quality and effectiveness of AI disclosures as mandated by the GDPR. By means of an online survey (N = 835), we investigated how data subjects expect to be informed about the automated processing of their data. We then conducted a content analysis of the AI disclosures of N = 100 companies and organizations. The combined findings reveal that current GDPR-mandated disclosures do not meet the expectations and needs of data subjects. Explanations drawn up following the guidelines of the generic formulations of the GDPR differ widely and are often vague, incomplete and lack transparency. In our conclusions we identify a path towards standardizing and optimizing AI information notices. (shrink)

In this wide-ranging conversation, Michael Hardt reflects on recent transformations within Empire. Several unique themes emerge concerning power and pedagogy as they intersect with subjectivity and global crisis. Drawing on the common in conjunction with the tradition of love in education uncovers a different path that attends to today’s real political, ecological, and social needs. Finally, a focus on collectivity points to a possible strategy—collective intellectuality—for educators to revise traditional notions of leadership to encourage more ethical, democratic, and sustainable futures. (...) Yet, what this looks like in practice remains for us to imagine. (shrink)

With the earliest known reference to angling with a fly dating from the Chou Dynasty, more than 2,300 years ago, it should come as no surprise that when asked to justify their passionate devotion to fly fishing, many anglers will refer to the rich and venerable literature the sport has generated. Ranging from Plutarch's references to Nile fishing in the Life of Antonius, to Pliny the Elder's Historia Naturalis, to the fifteenth century classic, Dame Julian Berner's The Treatyse of Fysshynge (...) wyth an Angle, to the sport's bible, the 17th century The Compleat Angler by Izaak Walton, to literary treatments in the work of authors such as John Donne, Gerard Manley Hopkins, William Butler Yeats, Ezra Pound and Ernest Hemingway, the wealth of literature devoted to fly fishing appears to be out of proportion to what is, ultimately, just a way of seducing an animal with a brain the size of a pea into inhaling a hook upon which some feathers, furs and tinsels have been lashed. What then, one may legitimately ask, is it about this sport that creates fanatical devotion on the part of its practitioners, who tend to regard it with such zeal and passion as is commonly reserved for art and religion?

At the very end of the 19th century, Gabriele Tarde wrote that all society was a product of imitation and innovation. This view regarding the development of society has, to a large extent, fallen out of favour, and especially so in those areas where the rational actor model looms large. I argue that this is unfortunate, as models of imitative learning, in some cases, agree better with what people actually do than more sophisticated models of learning. In this paper, I (...) contrast the behaviour of imitative learning with two more sophisticated learning rules (one based on Bayesian updating, the other based on the Nash-Brown-von Neumann dynamics) in the context of social deliberation problems. I show for two social deliberation problems, the Centipede game and a simple Lewis sender-receiver game, that imitative learning provides better agreement with what people actually do, thus partially vindicating Tarde.

In this paper I describe and analyze an economic situation involving two competitive organizations. I put forth the argument that because of the systemic nature of decision making relative to managing the requirements of utilizing a descriptive equation that determines how many people an economic system can support, that even if all the players in the situation act ethically, the results will still be harmful, and necessarily so, to the system and to many innocent people. I will demonstrate that harming (...) innocent people is required and morally defensible given the choices available. The best one can do is slow down the increase in disutilities and possibly operate the system within a range of acceptable behavior that minimizes the resulting harm to innocent people, even if we cannot entirely remove this harm. In this context ethics becomes the study of the acceptable as opposed to the preferable. (shrink)

Die Musikpädagogik als Disziplin begann sich erst Anfang des 19. Jahrhunderts zu konstituieren. Gleichwohl hat Johann Gottfried Herder zahlreiche musikpädagogische Ideen benannt und reflektiert. Als leidenschaftlicher Musikliebhaber und Pädagoge kreisten seine Gedanken in retrospektiver Ferne und interkultureller Weite, ohne theoriebildenden Anspruch für die Musikerziehung zu erheben. Dennoch wurde Herder häufig als Gewährsmann verschiedener ideologischer Perspektiven bemüht. Die Studie will sachlich, ehrlich und unbefangen aufräumen, indem sie erstens Herders Spuren zur Erziehung durch Musik gründlich folgt, zweitens Irrtümer sowie Missdeutungen aus dem (...) Weg räumt, um drittens Herder als Wegbereiter durch Dokumentation seiner immensen Rezeption zu würdigen. (shrink)

Cheap talk has often been thought incapable of supporting the emergence of cooperation because costless signals, easily faked, are unlikely to be reliable (Zahavi and Zahavi, 1997). I show how, in a social network model of cheap talk with reinforcement learning, cheap talk does enable the emergence of cooperation, provided that individuals also temporally discount the past. This establishes one mechanism that suffices for moving a population of initially uncooperative individuals to a state of mutually beneficial cooperation even in the (...) absence of formal institutions.

One of the more recalcitrant issues in the philosophy of time concerns the question of temporal asymmetry. Some theorists, many of them, like Einstein, physicists, believe that time is fundamentally reversible. According to this view, the physical universe is indifferent to the direction of time; consequently, something like an arrow of time is held to be a human subjective imposition on an otherwise temporally isotropic world. Another position, held by Alfred North Whitehead and contemporary process philosophers, maintains that temporal asymmetry (...) is a primitive condition of the universe, and that therefore even the most basic physical processes, such as those occurring at the subatomic level, display a distinct temporal direction. Finally, the philosopher of time J.T. Fraser (1978) claims that temporal asymmetry is an emergent feature of the universe, appearing for the first time with biogenesis. According to Fraser, with the emergence of life comes a present, or “now”, a temporal dimension whose absence in more primitive levels of cosmic evolution prohibits the attribution of an arrow of time to any pre-biotic entity.

Despite promising early work into the role of immune cells such as eosinophils in adipose tissue (AT) homeostasis, recent findings revealed that elevating the number of eosinophils in AT alone is insufficient for improving metabolic impairments in obese mice. Eosinophils are primarily recognized for their role in allergic immunity and defence against parasitic worms. They have also been detected in AT and appear to contribute to adipose homeostasis and drive energy expenditure, but the underlying mechanisms remain elusive. It has long (...) been recognized that immune cells such as macrophages respond to external signals to regulate adipose homeostasis and energy balance, however, less is known about the relevance of eosinophil activity in AT. As the authors propose in this review, given recent debate over the relative importance of their tissue‐specific abundance, the stage is now set for exploring the functionality and activation states of AT eosinophils.

Platonism has played a central role in Christianity and is essential to a deep understanding of the Christian theological tradition. At times, Platonism has constituted an essential philosophical and theological resource, furnishing Christianity with an intellectual framework that has played a key role in its early development, and in subsequent periods of renewal. Alternatively, it has been considered a compromising influence, conflicting with the faith's revelatory foundations and distorting its inherent message. In both cases the fundamental importance of Platonism, as (...) a force which Christianity defined itself by and against, is clear. Written by an international team of scholars, this landmark volume examines the history of Christian Platonism from antiquity to the present day, covers key concepts, and engages issues such as the environment, natural science and materialism.
