The subjective Bayesian interpretation of quantum mechanics and Rovelli’s relational interpretation of quantum mechanics are both notable for embracing the radical idea that measurement outcomes correspond to events whose occurrence is relative to an observer. Here we provide a detailed study of their similarities and especially their differences.

A recent paper has given a lucid treatment of Bell’s notion of local causality within the framework of the relational interpretation of quantum mechanics. However, the authors went on to conclude that the quantum violation of Bell’s notion of local causality is no more surprising than a common cause. Here, I argue that this conclusion is unwarranted by the authors’ own analysis. On the contrary, within the framework outlined by the authors, I argue that far from saving the notion of (...) ‘locality’ from the grip of Bell’s theorem, the authors have deprived it of a meaningful definition.

According to the subjective Bayesian interpretation of quantum mechanics, the instruments used to measure quantum systems are to be regarded as an extension of the senses of the agent who is using them, and quantum states describe the agent’s expectations for what they will experience through these extended senses. How can QBism then account for the fact that instruments must be calibrated before they can be used to ‘sense’ anything; some instruments are more precise than others; more precise instruments can (...) lead to discovery of new systems? Furthermore, is the agent ‘incoherent’ if they prefer to use a less precise instrument? Here we provide answers to these questions. (shrink)

A model of reality is called separable if the state of a composite system is equal to the union of the states of its parts, located in different regions of space. Spekkens has argued that it is trivial to reproduce the predictions of quantum mechanics using a separable ontological model, provided one allows for arbitrary violations of ‘dynamical locality’. However, since dynamical locality is strictly weaker than local causality, this leaves open the question of whether an ontological model for quantum (...) mechanics can be both separable and dynamically local. We answer this question in the affirmative, using an ontological model based on previous work by Deutsch and Hayden. Although the original formulation of the model avoids Bell’s theorem by denying that measurements result in single, definite outcomes, we show that the model can alternatively be cast in the framework of ontological models, where Bell’s theorem does apply. We find that the resulting model violates local causality, but satisfies both separability and dynamical locality, making it a candidate for the ‘most local’ ontological model of quantum mechanics.

In recent works, Časlav Brukner and Jacques Pienaar have raised interesting objections to the relational interpretation of quantum mechanics. We answer these objections in detail and show that, far from questioning the viability of the interpretation, they sharpen and clarify it.

"The four essays in this volume constitute Derrida's most explicit and sustained reflection on the art work as pictorial artifact, a reflection partly by way of philosophical aesthetics (Kant, Heidegger), partly by way of a commentary on art works and art scholarship (Van Gogh, Adami, Titus-Carmel). The illustrations are excellent, and the translators, who clearly see their work as both a rendering and a transformation, add yet another dimension to this richly layered composition. Indispensable to collections emphasizing art criticism and (...) aesthetics."--Alexander Gelley, Library Journal. (shrink)

This text proposes an evaluation of what remains of cinema in the age of the digital, and of an ever increased circulation between movie theatres and museums. Much has changed in the social and aesthetic status of cinema, at least since the appearance of video art; but cinema, in general, has not disappeared, quite to the contrary, and remains a very important social practice. Two important factors, however, have undergone deep changes: 1°, film no longer has the exclusivity of the (...) moving image, which it has to share with television and contemporary art; 2°, the recent hegemony of the digital image has driven film toward a massive return to the “Méliès path” of film art, that of a direct intervention on the film image. The contention here is that, though the art of film is obviously not what it was, it has kept a number of qualities which still make it the positive reference for any thinking of the moving image in general. The article puts forward three kinds of reasons to support this argument: 1°, cinema has invented a specific way to see moving images, resting on what is termed here the production of a gaze; 2°, time is essential to the film form itself; 3°, film is the only art which has developed an aesthetic of the encounter (with the real) – and the co-presence of these three ranges of value remain absolutely specific.

"The cinema is, as a photographic medium, an art form of light. But the mastery of lightning and the 'dark' side of his rhizomatic, interactive net have led very early to the configuration of shade and shadow and refer, ergo, to something which is perpetually related to all forms of figurative art. To film, 'night' means, however, something different, as it brings the configuration of the skies in a state of darkness with it. This is in disagreement with his usual (...) depiction. It entails embarking on a singular figurative project, which approximates a contradiction in itself. This project demonstrates the autonomy of the configuration process precisely through this contradiction.". (shrink)

The article discussed the idea of skilled helping in relation to what has been put forward as practical theological facilitation. It has been argued that various helping relationships, amongst which the author refers to coaching, facilitation, and therapy has more in common than what differentiates them if epistemology is viewed as a unifying concept. As such the scope of practical theology in terms of the contexts and themes in which it might be involved is said to widen. The public dimension (...) of the organisational context, more so than the congregational context, has been put forward as an important habitus of practical-theological facilitation. The organisational involvement of the practical-theological facilitator in terms of professional-vocational skilled helping takes on an actual role through facilitation and other helping modalities.

The study focused on the adventure-based experiential learning component of the North-West University peer helper training program. The aim of this study was to explore and describe a group of peer helpers’ subjective experiences of their participation in an ABEL program, with a focus on how these experiences related to the concept of grit. A total of 26 students at the North-West University, both male and female, participated in the study. A qualitative research approach with a case study research design (...) was used. The participants completed daily reflective diaries for the duration of the three-day ABEL program. After 3 months of performing their duties as peer helpers, the same individuals participated in focus group interviews. Themes were identified through inductive analysis and discussed regarding their relevance to the concept of grit. The main themes that emerged from both phases of data collection included intra-, inter-, and transpersonal/transcendent aspects, within which participants regularly referred to elements of grit. It was concluded that ABEL, due to its unique nature and demands, provides an ideal mechanism for the facilitation of personal growth on various levels. More specifically, through its clear association with the improvement and/or development of participants’ grit, it could equip these students to be more effective in their role as peer helpers.

While it is well-established that poverty and disease are intimately connected, the nature of this connection and the role of poverty in disease causation remains contested in scientific and social studies of disease. Using the case of HIV/AIDS in South Africa and drawing on a theoretically grounded analysis, this paper reconceptualises disease and poverty as ontologically entangled. In the context of the South African HIV epidemic, this rethinking of the poverty-disease dynamic enables an account of how social forces such as (...) poverty become embodied in the very substance of disease to produce ontologies of HIV/AIDS unique to South Africa.

The discovery of a new homonin species called Homo naledi evoked unprecedented interest, even outside the scientific disciplines who are researching extinct homonin species. The reason for this is that Prof. Lee Berger, attached to the University of the Witwatersrand and his team, known as the Rising Star-expedition, came to the conclusion that the fossils that were discovered in the Dinaledi cave room in Sterkfontein outside Johannesburg in 2013, were placed there deliberately. The theory postulates the possibility of symbolic or (...) ritual behaviour by a species that lived and later became extinct approximately 1 to 2 million years ago. If this is indeed the case, it also offers theologians the opportunity to join the conversation with regard to the evolvement of our spirituality and religiousness. This article is an attempt to render a contribution, with the data available to us, about the value of the prehistoric signs of spirituality with specific reference to the so-called cemetery theory. Together with this, other usable theories will be employed to consider the possible signs of ritual and symbolic behaviour by Homo naledi. The condition for a meaningful discussion about the evolvement of our spirituality and religiousness is that epistemological contours be clearly drawn. With the first part of the article these contours are drawn and with the second part the possible implications of the cemetery theory are reviewed. (shrink)

This volume brings together four of Jacques Derrida's essays on Maurice Blanchot's fictions: "Pace Not(s)," "Living on," "Title To Be Specified," and "The Law of Genre.".

"I shall speak of ghost, of flame, and of ashes." These are the first words of Jacques Derrida's lecture on Heidegger. It is again a question of Nazism--of what remains to be thought through of Nazism in general and of Heidegger's Nazism in particular. It is also "politics of spirit" which at the time people thought--they still want to today--to oppose to the inhuman. "Derrida's ruminations should intrigue anyone interested in Post-Structuralism. . . . . This study of Heidegger (...) is a fine example of how Derrida can make readers of philosophical texts notice difficult problems in almost imperceptible details of those texts."--David Hoy, London Review of Books "Will a more important book on Heidegger appear in our time? No, not unless Derrida continues to think and write in his spirit. . . . Let there be no mistake: this is not merely a brilliant book on Heidegger, it is thinking in the grand style."--David Farrell Krell, Research in Phenomenology "The analysis of Heidegger is brilliant, provocative, elusive."--Peter C. Hodgson, Religious Studies Review. (shrink)

This volume is a collection of twenty-three interviews given over the last two decades. It illustrates the extraordinary breadth of Derrida's concerns, touching upon such subjects as the teaching of philosophy, sexual difference and feminine identity, the media, AIDS, language and translation, nationalism, politics, and Derrida's early life and the history of his writings. Often, as in the interviews on Heidegger, on drugs, or on the nature of poetry, these interviews offer something available nowhere else in his work. The informality (...) of the interview process frequently leads to the most succinct and lucid explications of many of the most important and influential aspects of Derrida's thought. Sixteen of the interviews appear in English for the first time, including an interview conducted especially for this volume, concerning the recent exchange of letters in the New York Review of Books.

This brings together five pieces written by Jacques Derrida as extended lectures. The most important theme is Derrida's redefinition of speech acts and the 'event' as a particular kind of performative. The effects of globalization and mechanization, along with arising issues, provide a second constellation of themes. The first four essays involve a specific act of speech: the lie, the excuse, perjury and profession. The last two essays continue Derrida's powerful series of meditations on professional and institutional questions. The (...) final essay, 'Psychoanalysis Searches the States of Its Soul', confronts the task facing psychoanalysis today: coming to terms in new ways with worldwide cruelty and accommodating itself to the modern juridical concepts of crime against humanity. The phrase 'without alibi' (alibi, of course, being another speech act) is used throughout the essay as a leitmotif indicating that the responsibility psychoanalysis has to respond to globalization cannot be evaded.

An edition of three essays by the leading French philosopher and theorist Jacques Derrida on the ethical, political and linguistic issues posed by the act of 'naming'. Passions: An Oblique Offering is a reflection on the question of the response, on the duty and obligation to respond, and on the possibility of not responding - which is to say, on the ethics and politics of responsibility. Sauf le nom (Post Scriptum) considers the problematics of naming and alterity, or transcendence, (...) raised inevitably by a rigorous negative theology. Much of the text is organised around close readings of the poetry of Angelus Silesius. The final essay, Khora, explores the problem of space or spacing, of the word 'khora' in Plato's Timaeus. Even as it places and makes possible nothing less than the whole world, 'khora' opens, dislocates and displaces all the categories that govern the production of that world, from naming to gender.

One of Jacques Derrida’s richest and most provocative works, Life Death challenges and deconstructs one of the most deeply rooted dichotomies of Western thought: life and death. Here Derrida rethinks the traditional philosophical understanding of the relationship between life and death, undertaking multidisciplinary analyses of a range of topics, including philosophy, linguistics, and the life sciences. In seeking to understand the relationship between life and death, he engages in close readings of Freudian psychoanalysis, the philosophy of Nietzsche and Heidegger, (...) French geneticist François Jacob, and epistemologist Georges Canguilhem. Derrida gave his “Life Death” seminar over fourteen sessions between 1975 and 1976 at the École normale supérieure in Paris as part of the preparation for students studying for the agrégation, a notoriously competitive qualifying exam. The theme for the exam that year was “Life and Death,” but Derrida made a critical modification to the title by dropping the coordinating conjunction. The resulting title of Life Death poses a philosophical question about the close relationship between life and death. Derrida argues that death must be considered neither as the opposite of life nor as the truth or fulfillment of it, but rather as that which both limits life and makes it possible. Through these captivating sessions, Derrida thus not only questions traditional understandings of the relationship between life and death, but also ultimately develops a new way of thinking about what he calls “life death.”.

I shall speak of ghost [revenant], of flame and of ashes.And of what, for Heidegger, avoiding means.What is avoiding? Heidegger on several occasions uses the common word Vermeiden: to avoid, to flee, to dodge. What might he have meant when it comes to “spirit” or the “spiritual”? I specify immediately: not spirit or the spiritual but Geist, geistig, geistlich, for this question will be, through and through, that of language. Do these German words allow themselves to be translated? In another (...) sense: are they avoidable?Sein und Zeit : what does Heidegger say at that time? He announces and he prescribes. He warns [avertit]: a certain number of terms will have to be avoided . Among them, spirit . In 1953, more than twenty-five years later—and this was not just any quarter-century—in the great text devoted to Georg Trakl, Heidegger notes that Trakl always took care to avoid the word geistig. And, visibly, Heidegger approves him in this; he thinks the same. But this time, it is not Geist nor even geistlich that is to be avoided, but geistig.How are we to delimit the difference, and what has happened? What of this meantime? How are we to explain that in twenty-five years, between these two warning signals , Heidegger made a frequent, regular, marked use of all this vocabulary, including the adjective geistig? And that he often spoke not only of the word “spirit” but, sometimes yielding to the emphatic mode, in the name of spirit? Jacques Derrida is Directeur d’Études at the École des Hautes Études en Sciences Sociales and also teaches at the University of California, Irvine. His most recent contribution to Critical Inquiry is “Like the Sound of the Sea Deep within a Shell: Paul de Man’s War” .

This volume contains the speech given by Derrida at Emmanuel Levinas’s funeral on December 27, 1995, and his contribution to a colloquium organized to mark the first anniversary of Levinas’s death.

Cet ouvrage aurait pu s'intituler " matière et vie ". L'auteur nous guide sur le long chemin qui va des constituants élémentaires d'un jeune univers, dans lequel la vie est évidemment absente, jusqu'aux formes complexes de la matière. Il explique comment et pourquoi la matière se complexifie dans le coeur des étoiles de premières générations, dans la nébuleuse protosolaire, sur la jeune Terre envoie de différenciation, dans les premiers océans terrestres. Il décrit ce que l'on croit savoir, mais aussi passe (...) en revue tout ce que l'on ignore à propos de la génération spontanée des premières cellules vivantes. Lorsque la vie apparaît, l'histoire de la matière devient dépendante de l'évolution biologique. Après trois milliards d'années environ, celle-ci conduit à l'apparition de l'homme, seul être vivant capable de faire évoluer la matière. Ce livre propose ainsi une fresque d'une réelle ampleur, sans équivalent à ce jour, écrite pour être accessible à tous. Et pourtant, les questions abordées relèvent de nombreuses disciplines, comme l'astrophysique, la biologie, la chimie, le génie génétique et l'histoire des techniques. (shrink)

This volume reflects Derrida's engagement in the late 1970s with French political debates on the teaching of philosophy and the reform of the French university system. While addressing specific contemporary political issues, the essays deal mainly with much broader concerns. With his typical rigor and spark, Derrida investigates the genealogy of several central concepts which any debate about teaching and the university must confront. Thus there are essays on the 'teaching body', both the faculty corps and the strange interplay in (...) the French tradition between the mind and body of the professor; on the question of age in teaching, analyzed through a famous letter of Hegel; on the class, the classroom, and the socio-economic concept of class in education; on language, especially so-called 'natural languages' like French; and on the legacy of the revolutionary tradition, the Estates General, in the university.

Completing the translation of Derrida’s monumental work Right to Philosophy (the first part of which has already appeared under the title of Who’s Afraid of Philosophy?), Eyes of the University brings together many of the philosopher’s most important texts on the university and, more broadly, on the languages and institutions of philosophy. In addition to considerations of the implications for literature and philosophy of French becoming a state language, of Descartes’ writing of the Discourse on Method in French, and of (...) Kant’s and Schelling’s philosophies of the university, the volume reflects on the current state of research and teaching in philosophy and on the question of what Derrida calls a “university responsibility.” Examining the political and institutional conditions of philosophy, the essays collected here question the growing tendency to orient research and teaching towards a programmable and profitable end. The volume is therefore invaluable for the light it throws upon an underappreciated aspect of Derrida’s own engagement, both philosophical and political, in struggles against the stifling of philosophical research and teaching. As a founding member of the Research Group on the Teaching of Philosophy and as one of the conveners of the Estates General of Philosophy, Derrida was at the forefront of the struggle to preserve and extend the teaching of philosophy as a distinct discipline, in secondary education and beyond, in the face of conservative government education reforms in France. As one of the founders of the Collège International de Philosophie, he worked to provide a space for research in and around philosophy that was not accepted or legitimated in other institutions. Documenting and reflecting upon these engagements, Eyes of the University brings together some of the most important and incisive of Derrida’s works. (shrink)
