The great richness of the work of Louis Bouyer is well known. In his first publications, Bouyer initiates a return to the sources of the liturgy, the Word and the Fathers. Very characteristically of this movement is Le mystère pascal (1945), which rehabilitates theologically many profound views more or less forgotten. Nevertheless, we also find that, in this work, the author, after opening new avenues, comes to close them. The status Bouyer gives to Holy Saturday manifests this lack of consistency. (...) The present article attempts to explain this situation. At the end, Bouyer’s own approach appears to be a link between the theologies of Thomas Aquinas and Hans Urs von Balthasar. (shrink)

Antoine Arnauld and Pierre Nicole were philosophers and theologians associated with Port-Royal Abbey, a centre of the Catholic Jansenist movement in seventeenth-century France. Their enormously influential Logic or the Art of Thinking, which went through five editions in their lifetimes, treats topics in logic, language, theory of knowledge and metaphysics, and also articulates the response of 'heretical' Jansenist Catholicism to orthodox Catholic and Protestant views on grace, free will and the sacraments. In attempting to combine the categorical theory of (...) the proposition with a Cartesian account of knowledge, their Logic represents the classical view of judgment which inspired the modern transformation in logic and semantic theory by Frege, Russell, Wittgenstein and recent philosophers. This edition presents a new translation of the text, together with a historical introduction and suggestions for further reading. (shrink)

The paper presents a research programme for the neuroscience of consciousness called 'neurophenomenology' and illustrates it with a recent pilot study . At a theoretical level, neurophenomenology pursues an embodied and large-scale dynamical approach to the neurophysiology of consciousness . At a methodological level, the neurophenomenological strategy is to make rigorous and extensive use of first-person data about subjective experience as a heuristic to describe and quantify the large-scale neurodynamics of consciousness . The paper focuses on neurophenomenology in relation to (...) three challenging methodological issues about incorporating first-person data into cognitive neuroscience: first-person reports can be biased or inaccurate; the process of generating first-person reports about an experience can modify that experience; and there is an 'explanatory gap' in our understanding of how to relate first-person, phenomenological data to third-person, biobehavioural data.

Recent brain imaging studies using functional magnetic resonance imaging (fMRI) have implicated insula and anterior cingulate cortices in the empathic response to another’s pain. However, virtually nothing is known about the impact of the voluntary generation of compassion on this network. To investigate these questions we assessed brain activity using fMRI while novice and expert meditation practitioners generated a loving-kindness-compassion meditation state. To probe affective reactivity, we presented emotional and neutral sounds during the meditation and comparison periods. Our main hypothesis (...) was that the concern for others cultivated during this form of meditation enhances affective processing, in particular in response to sounds of distress, and that this response to emotional sounds is modulated by the degree of meditation training. The presentation of the emotional sounds was associated with increased pupil diameter and activation of limbic regions (insula and cingulate cortices) during meditation (versus rest). During meditation, activation in insula was greater during presentation of negative sounds than positive or neutral sounds in expert than it was in novice meditators. The strength of activation in insula was also associated with self-reported intensity of the meditation for both groups. These results support the role of the limbic circuitry in emotion sharing. The comparison between meditation vs. rest states between experts and novices also showed increased activation in amygdala, right temporo-parietal junction (TPJ), and right posterior superior temporal sulcus (pSTS) in response to all sounds, suggesting, greater detection of the emotional sounds, and enhanced mentation in response to emotional human vocalizations for experts than novices during meditation. Together these data indicate that the mental expertise to cultivate positive emotion alters the activation of circuitries previously linked to empathy and theory of mind in response to emotional stimuli..

Nonlocal “realistic” Leggett models can be considered refuted by the before-before experiment. “Single preferred frame” models are not refuted by this experiment but bear severe oddities.

Nietzsche once proclaimed himself the 'Buddha of Europe', and throughout his life Buddhism held enormous interest for him. While he followed Buddhist thinking in demolishing what he regarded as the two-headed delusion of Being and Self, he saw himself as advocating a response to the ensuing nihilist crisis that was diametrically opposed to that of his Indian counterpart. In this book Antoine Panaïoti explores the deep and complex relations between Nietzsche's views and Buddhist philosophy. He discusses the psychological models (...) and theories which underlie their supposedly opposing ethics of 'great health' and explodes the apparent dichotomy between Nietzsche's Dionysian life-affirmation and Buddhist life-negation, arguing for a novel, hybrid response to the challenge of formulating a tenable post-nihilist ethics. His book will interest students and scholars of Nietzsche's philosophy, Buddhist thought and the metaphysical, existential and ethical issues that emerge with the demise of theism. (shrink)

This paper analyzes an explicit instantiation of the program of “neurophenomenology” in a neuroscientific protocol. Neurophenomenology takes seriously the importance of linking the scientific study of consciousness to the careful examination of experience with a specific first-person methodology. My first claim is that such strategy is a fruitful heuristic because it produces new data and illuminates their relation to subjective experience. My second claim is that the approach could open the door to a natural account of the structure of human (...) experience as it is mobilized in itself in such methodology. In this view, generative passages define the type of circulation which explicitly roots the active and disciplined insight the subject has about his/her experience in a biological emergent process.

The capacity to stabilize the content of attention over time varies among individuals, and its impairment is a hallmark of several mental illnesses. Impairments in sustained attention in patients with attention disorders have been associated with increased trial-to-trial variability in reaction time and event-related potential deficits during attention tasks. At present, it is unclear whether the ability to sustain attention and its underlying brain circuitry are transformable through training. Here, we show, with dichotic listening task performance and electroencephalography, that training (...) attention, as cultivated by meditation, can improve the ability to sustain atten- tion. Three months of intensive meditation training reduced variability in attentional processing of target tones, as indicated by both enhanced theta-band phase consistency of oscillatory neural responses over anterior brain areas and reduced reaction time variability. Furthermore, those individuals who showed the greatest increase in neural response consistency showed the largest decrease in behav- ioral response variability. Notably, we also observed reduced variability in neural processing, in particular in low-frequency bands, regardless of whether the deviant tone was attended or unattended. Focused attention meditation may thus affect both distracter and target processing, perhaps by enhancing entrainment of neuronal oscillations to sensory input rhythms, a mechanism important for controlling the content of attention. These novel findings highlight the mechanisms underlying focused attention meditation and support the notion that mental training can significantly affect attention and brain function. (shrink)

Understanding the emergence of a tangible 4-dimensional space-time from a quantum theory of gravity promises to be a tremendously difficult task. This article makes the case that this task may not have to be carried. Space-time as we know it may be fundamental to begin with. I recall the common arguments against this possibility and review a class of recently discovered models bypassing the most serious objection. The generic solution of the measurement problem that is tied to semiclassical gravity as (...) well as the difficulty of the alternative make it a reasonable default option in the absence of decisive experimental evidence.

Ethical concerns are motivating the search for alternative methods to obtain pluripotent stem cells without destroying human embryos. The supporters of these methods stress the importance of ensuring that the biological entities used in these alternative methods are not “disabled or sick human embryos.” In this article the authors argue that biological entities bearing anomalies or alterations that directly inhibit the appearance of neural activity (DIANA anomalies) share the moral status of human organisms fulfilling the clinical criteria for brain death. (...) By contrast, in the absence of DIANA anomalies, the moral status of a person cannot be denied. National Catholic Bioethics Quarterly 7.2 (Spring 2007): 315–335. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:BOOK REVIEWS 347 Anoelus Silesius, le POlerin ChOrubinique. By Eugene Susini. (Paris: Presses Universitaires de France, 1964. 2 vols.) "II a fallu pratiquement attendre le vingti~me si~cle pour que ffit donn~e sa vdritable place Angelus Silesius (de son vrai nom Johannes Scheffier) tomb~ dans l'oubli ou presque pendant plus de deux cents ans," ~crit M. Eugene Susini, Professeur en Sorbonne, dans son introduction au P$lerin Ch~rubinique. Mais si les (...) travaux consacr~s ~ ce podte mystique sont ddj~ nombreux, on n'avait jusqu'~ present ~ditd en France que quelques fragments, ~parpill~s dans des anthologies. Depuis l'ouvrage de M. Henri Plard (1943), il n'y avait pas eu d'ddition qui present ~t ~ nouveau le texte original et une traduction en regard. C'est maintenant chose faite, et M. Susini fair plus que combler cette lacune. En effet, les textes d'Angelus Silesius (16241677 ) sont prdcddds d'une introduction historique, biographique et litt~raire, dtude substantielle sur le milieu off v~cut Angelus Silesius, et sur son itin~raire spirituel. L'originalitd profonde de ce catholique converti se ddgage de cette dtude, dont l'ampleur et la concision forcent l'admiration. Ce n'est pas tout. Ace premier volume un second fait suite, consaer~ ~ d'abondantes notes (178 p.) relatives aux distiques et aux quatrains; ces derni~res s'~elairent les unes les autres, et grace ~ une minutieuse critique interne et externe, ces vers sont replaces dans un contexte plus vaste que le prdsentateur a pris soin d'~clairer par de constantes r~f~rences ~ des passages d'autres oeuvres mystiques, ou des Ecritures elles-mdmes. Enfin, un index alphabdtique complete tr~s utilement ces notes (p. 179 s 257). On ne salt ce qu'il convient d'admirer le plus, le travail de l'~rudit et de l'historien, ou celui du traducteur. La t~iche n'dtait pas aisde; il fallait rendre en alexandrins ce qui avait dt~ compos~ de m~me, afin de laisser aux sentences non seulement leur saveur, mais aussi leur forme d'dpigrammes-proverbes. I1 faut dire que la r~ussite est totale. Le P~lerin Ch~rubinique est en m~me temps un ouvrage ddfinitif, car on ne volt pasce que pourrait apporter une nouvelle traduction, une prgsentation du texte original different, ou un nouveau recueil de notes--ces derni~res ~tant ici d'une grande ampleur.

By Koenraad W. Swart. (Archives Internationales d'Histoire des Idles, 7; The Hague : M. Nijhoff, 1964. Pp. xi + 272. Gld. 27.50.) "Seek and ye shall find!" Scholars have generally followed this injunction and found in history pretty much what they set out to discover. For a long time, the nineteenth century was seen as an age of progress, its own self-image seeming to bear this out. More recently our own concern with decadence has led us to discover similar views in earlier times. After A. E. Carter, 1 Professor Koenraad Swart has given us The Sense o] Decadence in NineteenthJCentury France (The Hague : 1964), the seventh volume to appear in Martinus Nijhoff's International Archives of the History of Ideas. This is a broader chronicle than Carter's. It presents the antecedents of the idea of decadence from antiquity to the French Revolution, its modern forms rooted in a diversity of romantic reactions, its fin-de-si~cle culmination and its (temporary) waning before the brief affirmative revival that preceded World War I. In terms of present preoccupations, this is a timely book. A solid concluding chapter sketches "the foreign perspective," in which French developments appear as part of a broader context. The study provides a mine of information, a convenient companion and counterindicator to Bury's Idea o] Progress. Why, then, is it a dull and unsatisfactory book? In the first place because, having suggested the existence of another dimension to the histoire de grand-papa, the history of ideas cannot be written as, simply, another version of the serial chronicle of events.

Heidegger opposait a la barbarie contemporaine l'exemplarite du style philosophique kantien. Mais les grands postkantiens le jugeaient plutot exemplairement barbare, parce que non thematise, impropre, et meme autocontradictoire. L'ouvrage prend au serieux ce verdict, pour mieux l'inverser. Il identifie le statut de la connaissance critique, elucide les procedures de validation qu'elle convoque et montre que referer les theses kantiennes au regime de discours qui les etablit permet de prendre la mesure de leur radicalite. Il etablit que le philosopher kantien releve (...) d'une reflexion qui signifie discursivite, et dont le theme transcendantal repugne a etre connu sur un mode objectivant. La fidelite de la connaissance critique a la nature de son theme ne peut toutefois l'autoriser a transgresser les limites qu'elle assigne a tout savoir. Les enonces critiques appellent donc un mode de probation qui les refere indirectement a l'intuition, ou au fait qui peut en tenir lieu. Forme du discours qui n'est pas sans effets de contenu: factualite d'un transcendantal impuissant a repondre a la question de son propre pourquoi, facticite de la structure qui possibilise une connaissance dont elle partage la contingence metaphysique, indeductibilite d'une loi morale dont l'absoluite sort renforcee de ne pouvoir etre expliquee et ne cesse de feconder la pensee finie.

As a singular witness and actor of the tumultuous 20th century, Ernst Jünger remains a controversial and enigmatic figure known above all for his vivid autobiographical accounts of experience in the trenches of the First World War. This article will argue that throughout his entire oeuvre, from personal diaries to novels and essays, he never ceased to grapple with what he viewed as the central question of the age, namely that of the problem of nihilism and the means to overcome (...) it. Inherited from Nietzsche’s diagnosis of Western civilization in the late 19th century, to which he added an acute observation of the particular role of technology within it, Jünger would employ this lens to make sense of the seemingly absurd industrial slaughter of modern war and herald the advent of a new voluntarist and bellicist order that was to imminently sweep away timorous and decadent bourgeois societies obsessed with security and self-preservation. Jünger would ultimately see his expectations dashed, including by the forms of rule that National Socialism would take, and eventually retreated into a reclusive quietism. Yet he never abandoned his central problematique of nihilism, developing it further in exchanges with Martin Heidegger after the Second World War. And for all the ways in which he may have erred, his life-long struggle with meaning in the age of technique and its implications for war and security continues to make Jünger a valuable interlocutor of the present.

In the present article I attribute to the common topic in the Rhetoric a two-fold suggestive function and a guarantee function. These three functions are possible because this type of topic, while often quite abstract, nevertheless contains thought-steering, substantial terms, and formulates a generally empirical or normative endoxon. Assuming that according to Aristotle an enthymeme has at least two premises, it would appear that a common topic is the abstract principle behind the often implicit major premise. This means that the (...) topic may be regarded as the – generalizing – if-then statement in a modern argumentation scheme. Therefore it should be possible to see the enthymemes of Rhetoric 2.23 as a combination of a logical argument form (which can usually be reconstructed as modus ponens) and an argumentation scheme – even though we may not attribute this idea to Aristotle himself.

John Law left a remarkable legacy of economic concepts from a time when economic conceptualization was very much at an embryonic stage. Yet he is best known--and generally dismissed--today as a rake, duellist, and gambler. This intellectual biography offers a new approach to Law, one that shows him to have been a significant economic theorist with a vision that he attempted to implement as policy in early-eighteenth-century Europe. Law's style, marked by a clarity and use of modern terminology, stands out (...) starkly against the turgid prose of many of his contemporaries. His vision of a monetary and financial system was certainly one of a later age, for Law believed in an economy of banknotes and credit where specie had no role to play. Ultimately Law failed as a policy-maker, in part because of the entrenchment of the financiers and their aristocratic backers and in part because of theoretical flaws in his vision. His struggle for power took place against the background of Europe's first major stock boom and collapse. The collapse of the Mississippi System, which he had conceived, and the South Sea Bubble led to a lasting impression of Law as a failure. It is this impression that Antoin Murphy seeks to dispel.

Synthetic biology aims at reconstructing life to put to the test the limits of our understanding. It is based on premises similar to those which permitted invention of computers, where a machine, which reproduces over time, runs a program, which replicates. The underlying heuristics explored here is that an authentic category of reality, information, must be coupled with the standard categories, matter, energy, space and time to account for what life is. The use of this still elusive category permits us (...) to interact with reality via construction of self-consistent models producing predictions which can be instantiated into experiments. While the present theory of information has much to say about the program, with the creative properties of recursivity at its heart, we almost entirely lack a theory of the information supporting the machine. We suggest that the program of life codes for processes meant to trap information which comes from the context provided by the environment of the machine. (shrink)

Attention to internal body sensations is practiced in most meditation traditions. Many traditions state that this practice results in increased awareness of internal body sensations, but scientific studies evaluating this claim are lacking. We predicted that experienced meditators would display performance superior to that of nonmeditators on heartbeat detection, a standard noninvasive measure of resting interoceptive awareness. We compared two groups of meditators (Tibetan Buddhist and Kundalini) to an age- and body mass index-matched group of nonmeditators. Contrary to our prediction, (...) we found no evidence that meditators were superior to nonmeditators in the heartbeat detection task, across several sessions and respiratory modulation conditions. Compared to nonmeditators, however, meditators consistently rated their interoceptive performance as superior and the difficulty of the task as easier. These results provide evidence against the notion that practicing attention to internal body sensations, a core feature of meditation, enhances the ability to sense the heartbeat at rest. (shrink)

Results of recent research on hydatidiform moles and teratomas show that during pregnancy the embryo does not receive any message or information from the mother able to control the mechanisms of development or to produce the type of cellular differentiation necessary for building the tissues of the new human adult. Thus, the biological identity of the new human being does not depend on the sojourn in the uterus; the preimplantation embryo is the same individual of the human species as the (...) adult, into whom the embryo can in principle develop.

Dans un monde dominé par les conflits, il arrive qu’il faille se défendre. L’invention des armes a évolué en parallèle avec le savoir technique, puis scientifique, et il est même arrivé que la recherche d’applications militaires ait joué un rôle moteur dans la découverte scientifique. Lorsque les armes ne servent pas à attaquer d’autres nations, leur fabrication et leur commerce se justifient morale- ment. Il faut cependant qu’elles ne puissent échapper à ceux qui les construisent et doivent en contrôler la (...) diffusion. Facilement mise en œuvre, la guerre utilisant des organismes vivants ou ce qu’ils pro- duisent comme armes est très ancienne. Or l’originalité des êtres vivants est qu’ils se multiplient, qu’un seul individu suffit à recouvrir la Terre de ses descendants. La biologie ne se prête jamais à un usage militaire moralement défendable parce que le confinement au champ de bataille est impossible. De ce fait, les applications de la biologie ont été vite écartées du domaine de la Défense permise par les traités internationaux.

According to portfolio managers, agriculture in general, and farmland in particular, can be considered an emerging asset class. Specialized financial vehicles, such as private equity and mutual funds, are emerging and competing to attract potential investment in this asset class. In recent years, there has been significant development of such vehicles targeting South Africa’s farming sector. These innovations are led by a group of market intermediaries who endeavour to “re-shape” South African farmland as an opportunity for institutional investors. These “pioneers” (...) engage in a multifaceted mediation process between global financial investors on one hand, and the South African agricultural sector on the other. Drawing upon an empirical study of such intermediaries in South Africa, this paper analyses the concrete mechanisms that facilitate this particular form of commodification. The paper presents and compares the intermediaries, giving particular attention to their structure, governance mechanisms and asset allocations within this “market in the making”. It describes how intermediaries develop different paths of asset valorization to unlock the “financial value” of South African farmlands. But, it also highlights some of the difficulties faced in the process of translating between international investors and local managers, questioning the “land-asset fiction” that is materializing through the subordination of farmland to the needs of financial society.

It is common to argue that something x is distinct from something y by pointing out that x and y do not share all their essential properties. I show that arguments of this type are unsound. This unsoundness is rooted in the fact that sentences of the form ‘x is essentially F’ are ambiguous. Under one reading, the sentence says of x that it has a property of a unique and special kind. Interpreted in that way, the sentence is false, (...) for there are no such properties. Under another reading, the sentence says of x that it has a property and adds that this property is essential to x. Interpreted in that way, the sentence may be true but it does not allow to reach the desired conclusion that x is distinct from y. Thus, if someone argues that x is distinct from y by pointing out that x and y differ in essential properties, they face the following dilemma: either one of the argument’s premises implies the existence of the special property and it is false, or none of the premises implies the existence of the special property and the argument is invalid.

In the following article, starting from a progressive understanding of his own subjectivity, a determining factor in developing his capacity to listen to adolescents, the author puts forward the hypothesis that a professional position he describes as "in-between" requires rigor and flexibility, enabling professionals to remain permeable to the unconscious mobilizations of the adolescent-subjects as well as to his own. The author will draw on the results of a longitudinal, partnership-based study that he conducted with ten adolescents, from 2015 to (...) 2020, involving a team of specialized prevention educators. More specifically, the author will retrospectively analyze some excerpts from his encounter with one of the teenagers to reveal possible ways in which a "professional of the social bond" might adopt a rigorous in-between position.

We argue that ecology in general and biodiversity and ecosystem function research in particular need an understanding of functions which is both ahistorical and evolutionarily grounded. A natural candidate in this context is Bigelow and Pargetter’s evolutionary forward-looking account which, like the causal role account, assigns functions to parts of integrated systems regardless of their past history, but supplements this with an evolutionary dimension that relates functions to their bearers’ ability to thrive and perpetuate themselves. While Bigelow and Pargetter’s account (...) focused on functional organization at the level of organisms, we argue that such an account can be extended to functional organization at the community and ecosystem levels in a way that broadens the scope of the reconciliation between ecosystem ecology and evolutionary biology envisioned by many BEF researchers. By linking an evolutionary forward-looking account of functions to the persistence-based understanding of evolution defended by Bouchard and others, and to the theoretical research on complex adaptive systems, we argue that ecosystems, by forming more or less resilient assemblages, can evolve even while they do not reproduce and form lineages. We thus propose a Persistence Enhancing Propensity account of role functions in ecology to account for this overlap of evolutionary and ecological processes. (shrink)
