Although young children might be uncertain about the nature of certain representations, most modern adults would explicitly maintain that photographs have no ongoing physical connection the objects that they depict. We demonstrate here in three studies that destruction of a photograph of a sentimental object produces significantly more electrodermal activity than destruction of photographs of other control objects. This response is not attributable to anxiety about being observed whilst destroying the picture, nor is it entirely due to simple visual association (...) ‐ the same response occurs when the photograph does not resemble the object. We suggest that this effect may reflect a tacit acceptance of “sympathetic magic”. (shrink)

The prime number theorem, established by Hadamard and de la Vallée Poussin independently in 1896, asserts that the density of primes in the positive integers is asymptotic to 1/ln x. Whereas their proofs made serious use of the methods of complex analysis, elementary proofs were provided by Selberg and Erdos in 1948. We describe a formally verified version of Selberg's proof, obtained using the Isabelle proof assistant.

In lieu of an abstract, here is a brief excerpt of the content:276 HISTORY OF PHILOSOPHY appointment as the shepherd of the sheep from Christ. Nevertheless, his successors are chosen by men. Thus they are not of divine appointment and their power, in any case limited by Scriptural precept and natural law, is strictly circumscribed. Since they are placed in their position by men, they can be judged and deposed by men if they misuse their power. Throughout his career Ockham (...) violently repudiated the Avignonese papacy because it "professed errors and manifest heresies" and practiced injustice both in Church and state. He likewise regarded the college of cardinals as a purely human administrative institution and denied that they, along with the pope, were successors of the apostles. Since the Roman Church as well as the general Council could err, Ockham held that on occasion it is necessary to defend the true faith against the Roman Church, the pope, the general Council, and all the bishops and clergy (p. 277). The chief bond of Christians is the true faith. This is found both in the Scriptures and in tradition. This faith is to be maintained in its purity by true popes and general Councils. Their fidelity to the faith is the only guarantee of their authority. Therefore, a denial of, or a deviation from, the orthodox faith is heresy which he regarded as the major crime. De Lagarde severely criticizes Ockham by claiming that he reduced the Church to an aggregate of individuals bound together by common faith alone. This was destructive of the Church considered as a hierarchical and ~cramental institution. He traces Ockham's influence upon the dominant personalities of the subsequent decades all the way to Luther. The outstanding nominalists like Pierre d'Ailly and Jean Gerson, and reformers like Dietrich of Niem, John Wyclif, and John Huss, were either his professed disciples or were deeply influenced by Ockham. It may be remarked that the two last-named thinkers can hardly be included in this category: de Lagarde was either poorly informed or biased. For although he quotes in his support the two-volume works of Dora Paul de Vooght (L'h~rgsle de Jean Huss and Huss/ana), he ignores the general characterizations and the careful distinctions de Vooght makes between the positions of these two men, and repeats the uncritical views against which de Vooght energetically protests. It may also be added that the author omits a bibliography which is essential to a work of this kind. Nevertheless, his work is a massive and enlightening contribution to the hitherto neglected study of the post-Thomistic thinkers of the fourteenth century, among whom William of Ockham occupies a dominant place. MATr~sw SPINKA Claremont Graduate School and University Center Giordano Bruno and the Hermetic Tradition. By Frances A. Yates. (Chicago, University of Chicago Press, 1964. Pp. xiv + 466. $7.50.) In many ways the Renaissance of western civilization is reminiscent of Graeco-Roman Hellenism. While it is true that this parallelism cannot be drawn too closely, the similarity of the cultural forces facing both eras is instructive. This parallel suggests the importance of the resurgence of Hermetic gnosticism during the period from the fifteenth through the seventeenth centuries for an understanding of the religious and scientific developments taking place at this time. It is to this point that Profes~r Yates has written a major work of scholarship in the history of ideas. The importance of the Hermetic tradition in the intellectual framework of Renaissance religion and science is placed in its historical evolution from the time of the recovery of the texts and their translation into Latin by Ficino until its gradual decay in the seventeenth century after the correct dating of the texts by Isaac Casaubon. Obviously with so broad an undertaking it would be impossible to treat adequately in one volume the philosophical import of the ideas of the Hermetic texts and their development. Professor Yates wisely chooses Giordano Bruno as the focal point for her penetrating analysis of the Hermetic tradition as a philosophical movement. This has great significance for the student of Bruno, for as she remarks: "... it is only in putting him into the context of the history of Hermeticism in the Renaissance... (shrink)

The options in a decision problem generally have outcomes with common features. Putting aside the common features simplifies deliberations, but the simplification requires a philosophical justification that this book provides.

Schelling und Hegel benutzen in ihren philosophischen Texten mathematische und naturwissenschaftliche Modelle wie Unendlichkeit oder Gleichgewicht. Die Strukturen dieser Begriffe liefern einen Massstab fur den Vergleich der Positionen Schellings und Hegels, der fur Schellings Identitatsphilosophie und Hegels erste Jenaer Schriften durchgefuhrt wird. Als wichtigstes Resultat kann eine grundlegende Differenz zwischen beiden Positionen bereits um 1801 nachgewiesen und gezeigt werden, dass diese auf einer unterschiedlichen Auffassung der Rolle des Absoluten beruht.

The relationship between students and higher education is seen to have become increasingly transactional. We approach the study of the student–HE relationship in a novel way, by focusing on students’ behaviour post-university, rather than on student narratives. Conceptually, the article builds on multidimensional views of student engagement and the differentiation between psychological transactional contracts – where students who achieve better academic results are more likely to donate – and relational contracts – where students donate more following engagement in social experiences. (...) Making use of longitudinal data on donation behaviour from over 50,000 alumni from an English university over two decades, we find that while students who get better degree outcomes are more likely to donate, the association between participation in social experiences and donations is much stronger. This questions prevalent transactional models of HE and underlines the limitations of purely consumerist views of the relation between students and higher education institutions, even in the marketized UK context.

An agent often does not have precise probabilities or utilities to guide resolution of a decision problem. I advance a principle of rationality for making decisions in such cases. To begin, I represent the doxastic and conative state of an agent with a set of pairs of a probability assignment and a utility assignment. Then I support a decision principle that allows any act that maximizes expected utility according to some pair of assignments in the set. Assuming that computation of (...) an option's expected utility uses comprehensive possible outcomes that include the option's risk, no consideration supports a stricter requirement. (shrink)

Die MISCELLANEA MEDIAEVALIA präsentieren seit ihrer Gründung durch Paul Wilpert im Jahre 1962 Arbeiten des Thomas-Instituts der Universität zu Köln. Das Kernstück der Publikationsreihe bilden die Akten der im zweijährigen Rhythmus stattfindenden Kölner Mediaevistentagungen, die vor über 50 Jahren von Josef Koch, dem Gründungsdirektor des Instituts, ins Leben gerufen wurden. Der interdisziplinäre Charakter dieser Kongresse prägt auch die Tagungsakten: Die MISCELLANEA MEDIAEVALIA versammeln Beiträge aus allen mediävistischen Disziplinen - die mittelalterliche Geschichte, die Philosophie, die Theologie sowie die Kunst- und (...) Literaturwissenschaften sind Teile einer Gesamtbetrachtung des Mittelalters. (shrink)

The centrality of death rituals has in anthropologically informed studies of Buddhism been little documented. The current volume brings together a range of perspectives on Buddhist death rituals including ethnographic, textual, historical and theoretically informed accounts, and presents the diversity of the Buddhist funeral cultures of mainland Southeast Asia and China. It arises out of the University of Bristol's Centre for Buddhist Studies research project Buddhist Death Rituals in Southeast Asia and China, funded by the United Kingdom's Arts and Humanities (...) Research Council. This project involved extensive new research in Thailand, Laos and China. Other items from that project included several public exhibitions, extensive stills photographs, and several video films. The project-team produced two 30 minutes films on the ghost festival in Laos and China, one on urban funerals in Chiang Mai (Thailand) and several shorter clips dealing with funeral cultures in Laos, Thailand and China. Most of this material (and an extensive bibliography on the topic) is available free of charge from the project website located at the webpage of the Department of Theology and Religious Studies (Centre for Buddhist Studies) at the University of Bristol.

This article contends that the evolution toward interdisciplinary collaboration that we are witnessing in the sciences must also occur in the humanities to ensure their very survival. That is, humanists must be open to working with scientists and social scientists interested in similar research questions and vice versa. Digital humanities is a positive first step. Complexity science should be the next step. Even though much of the ground-breaking work in complexity science has been done in the natural sciences and mathematics, (...) it can, if critically adapted, provide the needed metaphor for a broad integration of disciplines, humanistic and otherwise. Given its almost a-disciplinary nature, a complexity approach to the research problems in the humanities necessarily breaks down silos. Moreover, it can restore and reframe the seamless intellectual fabric sought by researchers before the atomization of the various disciplines in the nineteenthcentury academy. (shrink)

What should authorities establish as the job of ethics committees and review boards? Two answers are: review of proposals for consistency with the duly established and applicable code and review of proposals for ethical acceptability. The present paper argues that these two jobs come apart in principle and in practice. On grounds of practicality, publicity and separation of powers, it argues that the relevant authorities do better to establish code-consistency review and not ethics-consistency review. It also rebuts bad code and (...) independence arguments for the opposite view. It then argues that authorities at present variously specify both code-consistency and ethics-consistency jobs, but most are also unclear on this issue. The paper then argues that they should reform the job of review boards and ethics committees, by clearly establishing code-consistency review and disestablishing ethics-consistency review, and through related reform of the basic orientation, focus, name, and expertise profile of these bodies and their actions.

Canada has recently published a new Clinical Practice Guideline on the diagnosis and management of brain death. It states that consent is not necessary to carry out the interventions required to make the diagnosis. A supporting article not only sets out the arguments for this but also contends that ‘UK laws similarly carve out an exception, excusing clinicians from a prima facie duty to get consent’. This is supplemented by the claim that recent court decisions in the UK similarly confirm (...) that consent is not required, referencing two judgements inBattersbee. We disagree with the authors’ interpretation of the law on consent in the UK and argue that there is nothing inBattersbeeto support the conclusion that consent to testing is not necessary. Where there is a disagreement about testing for brain death in the UK, court authorisation is required. (shrink)

Artificial intelligence (AI) will drastically change the healthcare system. Radiology is one speciality that is most affected as AI algorithms are increasingly used in diagnostic imaging. AI‐enhanced health technologies will, inter alia, increase workflow efficiency, improve diagnostic accuracy, reduce healthcare‐related costs, and help alleviate medical personnel shortages in under‐resourced settings. However, the development of AI‐enhanced technologies in healthcare is fraught with legal, ethical, and human rights concerns. Currently, the use of AI in South African healthcare is not governed by sui (...) generis legislation or ethical guidance focused exclusively and specifically on AI, although various provisions and principles from law and ethics find application. This article outlines these normative principles and explains their relationship with the extant legal obligations and regulatory framework as applied to the use of AI in radiology services in South Africa. The article concludes with three key recommendations for radiology practitioners using AI in South Africa. These are the need for: vigilant monitoring of AI use in practice, reforms to the liability framework, and appropriate guidance from local regulators and the Health Professions Council of South Africa on the ethical use of AI.

Extends the ideas of social constructivism to the philosophy of mathematics, developing a powerful critique of traditional absolutist conceptions of mathematics, and proposing a reconceptualization of the philosophy of mathematics.

This paper provides an axiomatic formalization of a theory of foundational relations between three categories of entities: individuals, universals, and collections. We deal with a variety of relations between entities in these categories, including the is-a relation among universals and the part-of relation among individuals as well as cross-category relations such as instance-of, member-of, and partition-of. We show that an adequate understanding of the formal properties of such relations – in particular their behavior with respect to time – is critical (...) for formal ontology. We provide examples to support this thesis from the domain of biomedicine. (shrink)

This article outlines the features and application of a set of model curriculum materials that utilize eco-democratic principles and humanities-based content to cultivate critical analysis of the cultural foundations of socio-environmental problems. We first describe the goals and components of the materials, then discuss results of their use in two different types of classrooms: an undergraduate humanities seminar at a mid-sized four-year college, and a developmental writing course at a community college.

We propose an ontological theory that is powerful enough to describe both complex spatio-temporal processes and the enduring entities that participate therein. For this purpose we introduce the notion a directly depicting ontology. Directly depicting ontologies are based on relatively simple languages and fall into two major categories: ontologies of type SPAN and ontologies of type SNAP. These represent two complementary perspectives on reality and employ distinct though compatible systems of categories. A SNAP (snapshot) ontology comprehends enduring entities such as (...) organisms, geographic features, or qualities as they exist at some given moment of time. A SPAN ontology comprehends perduring entities such as processes and their parts and aggregates as they unfold themselves through some temporal interval. We give an axiomatic account of the theory of directly depicting ontologies and of the core parts of the metaontological fragment within which they are embedded. (shrink)

In this paper, I focus on three issues intertwined in current debates between endurantists and perdurantists—(i) the dimension of persisting objects, (ii) whether persisting objects have timeless, or only time-relative, parts, and (iii) whether persisting objects have proper temporal parts. I argue that one standard endurantist position on the first issue is compatible with standard perdurantist positions on parthood and temporal parts. I further argue that different accounts of persistence depend on the claims about objects' dimensions and not on the (...) auxiliary claims about parthood and temporal parts. (shrink)
