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..

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)

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)

We use the theory of triposes to prove that every locale H is the set of truth values of a complete and co-complete quasi-topos into which the category of topological spaces embeds and the topos of sheaves over H reflectively embeds.

We introduce a typed version of the intuitionistic epsilon calculus. We give a categorical semantics of it introducing a class of categories which we call \-categories. We compare our results with earlier ones of Bell :323–337, 1993).

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.

The discovery of the concrete basis for genes, and especially the clarification of mechanisms regulating gene expressions (in particular those that bear on the stepwise processing of hereditary information from the sequences of DNA nucleotides to the proteins) was to give flesh to the concept of a genetic program, for these regulations introduce relationships of order between the various elements of information contained in the genes. These order relations are then revealed during the time-dependent expression of the genetic program. They (...) can lead, in the case of a given program, to a plethora of particular outcomes, because the number of possible combinations rapidly becomes enormous. Since the discoveries of Jacob and Monod, it is clear that the genes specifying the regulatory functions will be responsible for phenotypic variability, especially for the apparently ideal adaptation of a living organism to its environment, and more generally for all the genotype-bound manifestations as they unfold in time. -/- Thus we are led to consider three particular characteristics that allow for the representation of living beings: a program, which summarizes the hereditary constraints and is, in fact, the abstract notion underlying the definition of all individuals in a given class (species); an initial state of the system that represents the context in which the program must express itself at the time of the individual's birth; and a particular outcome of each program, which coincides with individual development. The set of all outcomes constitutes the genetic envelope and allows the essential characteristics of the program to be obtained by induction. Theoretically, a structured set equivalent to the aforementioned one could be reconstructed by providing the program, the initial state, and the totality of the events of the external environment, producing any interaction whatever with the individual. -/- As a consequence, the observation of a phenotype does not tell in any straightforward way, what is the direct consequence of the expression of a particular gene, or of a specific feature of the environment. A phenocopy is a particular example of a phenotype that is the result of a gene expression mimicking a particular gene-directed phenotype, without however corresponding to a pparticular mutation of a known gene.

Assembly of minimal genomes revealed many genes encoding unknown functions. Three overlooked functional categories account for some of them. Cells are prone to make errors and age. As a first key function, discrimination between proper and changed entities is indispensable. Discrimination requires management of information, an authentic, yet abstract, cur- rency of reality. For example proteins age, sometimes very fast. The cell must identify, then get rid of old proteins without destroying young ones. Implementing discrimination in cells leads to the (...) second set of functions, usually ignored. Being abstract, information must nevertheless be embodied into material entities, with unavoidable idiosyncratic properties. This brings about novel unmet needs. Hence, the buildup of cells elicits specific but awkward material implementations, ‘kludges’ that become essential under particular settings, while difficult to identify. Finally, a third functional category char- acterizes the need for growth, with metabolic implementations allowing the cell to put together the growth of its cytoplasm, membranes, and genome, spanning different spatial dimensions. Solving this metabolic quandary, critical for engineering novel synthetic biology chassis, uncovered an unexpected role for CTP synthetase as the coordinator of nonhomothetic growth. Because a significant number of SynBio constructs aim at creating cell factories we expect that they will be attacked by viruses (it is not by chance that the function of the CRISPR system was identified in industrial settings). Substantiating the role of CTP, natural selection has dealt with this hurdle via synthesis of the antimetabolite 30-deoxy-30,40-didehydro- CTP, recruited for antiviral immunity in all domains of life.

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.

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. La Convention de 1972 sur l’Interdiction des Armes Biologiques et à Toxines (CIABT), entrée en vigueur en 1975, est aujourd’hui signée par 183 pays (ratifiée par 175) sur un total de 193, sans compter Taïwan qui l’a ratifiée mais n’est pas reconnu par l’ONU. Elle interdit la mise au point, la fabrication, l’acquisition, le transfert, la conservation, le stockage et l’utilisation des armes bio- logiques et à toxines. Elle constitue un élément essentiel de la lutte contre la prolifération des armes de destruction massive. (shrink)

L’article analyse les effets de la cohabitation sur un même terrain, d’un sociologue, enquêtant sur les élèves d’une classe préparatoire pour des bacheliers d’origine modeste, et d’une équipe de tournage réalisant un documentaire à leur sujet. Analysant la réception différenciée du tournage parmi les élèves et ses effets sur la conduite de l’enquête, l’article revient sur la collaboration entre le sociologue et les réalisateurs. Il montre comment cette expérience, malgré les difficultés qu’elle suscite, peut aussi s’avérer heuristique.

In Social Justice in Practice, Juha Räikkä addresses a wide variety of subjects, tackling each one with competence and originality. The twelve essays collected in the book cover topics such as the relationship between theory and practice, the impact of “ideal justice” and its requirements on individuals’ expectations, the difficulties connected to the selection of second-best options and the role of presumption rules. In addition, Räikkä focuses on conspiracy theories, on the right to privacy, on the possibility of concealing information (...) in social relations, as well as on the moral dilemmas connected to “alien beliefs”, namely beliefs beyond individuals’ self-awareness and conflicting with their considered judgments. He also discusses the fairness of demanding forgiveness and clarifies the notion of self-deception, by investigating its connection with adaptive preferences and religious beliefs. Räikkä makes each topic accessible and appealing also to readers unfamiliar with them. Moreo .. (shrink)

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)

"Comment faites-vous pour défendre l'assassin d'un enfant?" C'est souvent cette question que les avocats pénalistes entendent à propos de leur métier. L'avocat est représenté, dans la fiction, sous les traits d'un être ambigu, sans cesse sur le fil... La réalité est sans doute tout autre. C'est elle que ce livre tente d'approcher en comblant un manque dans les réflexions contemporaines de l'avocature. Rares sont, en effet, les travaux qui abordent l'éthique de l'avocat pénaliste. Quelles sont ses interrogations, ses incertitudes lorsqu'il (...) est confronté à des choix de défense? A travers une enquête menée auprès d'avocats, l'auteur s'intéresse aux intentions, aux pratiques quotidiennes effectives et aux enjeux de responsabilité du pénaliste. Comment les mutations juridiques et politiques de la défense pénale orientent-elles les valeurs de l'avocat et sa manière d'agir? Par-delà la dimension déontologique de son métier, quelles relations d'ordre éthique l'avocat entretient-il avec lui-même mais aussi avec l'autre : son client, qu'il soit prévenu, accusé ou victime, les jurés, les magistrats? Peut-on parler du rapport de l'avocat à la vérité? Cette vérité est-elle spécifique? Plurielle? Le procès équitable permet-il d'affirmer une égalité des armes devant la justice? Comment l'avocat peut-il construire des lignes de défense tout en restant partenaire de justice? En définitive, est-il possible de comprendre l'acte même de défense des actes extrêmes, des crimes monstrueux sans prendre conscience de la complexité d'une réflexion éthique? Avocats, magistrats, policiers, journalistes, bâtonniers, et bien sûr tous ceux qui se destinent à ces professions, et puis encore les citoyens qui s'intéressent à la justice et les citoyens qui la découvrent en tant que jurés, tous ceux-là, pour des raisons très diverses, tireront profit de la lecture de cet ouvrage.

Blaise Pascal is a marquee name, yet little read outside France. Antoine Compagnon provides an ideal introduction to one of the great intellects, contextualizing Pascal in his own time and offering insightful readings of the Pensées and the Provincial Letters. Compagnon proves a welcoming guide to Pascal's challenging and rewarding thought.

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)
