This study examines the relationships of servant leadership to organizational commitment, voice behaviors, and antisocial behaviors. Adopting a multifaceted approach to commitment, we hypothesized that servant leadership would be positively related to affective, normative, and perceived sacrifice commitment, but unrelated to few alternatives commitment. We further hypothesized that affective commitment would be positively related to voice behaviors, controlling for the other commitment components, and would mediate a positive relationship between servant leadership and voice behaviors. Similarly, we hypothesized that normative commitment (...) would be negatively related to antisocial behaviors, controlling for the other commitment components, and would mediate a negative relationship between servant leadership and antisocial behaviors. These predictions were tested using matched data from a sample of 181 Canadian customer service employees and their managers. Results largely supported the above predictions. Importantly, affective commitment mediated a positive relationship between servant leadership and voice behaviors. Yet, while servant leadership was positively related to normative commitment and the latter was negatively related to antisocial behaviors, the indirect effect of servant leadership on these behaviors through normative commitment was nonsignificant. Theoretical implications and future research directions are discussed. (shrink)

Dall-E2 and Stable Diffusion promote their text-to-image models based on their level of (photo)realism. The use of photographic language is not superficial or accidental but indicative of a broader tendency in computer science and data practice. To nuance the general application of photorealism, I position the term alongside photographic realism and computational photorealism. To contextualize important nuances between these three terms, contemporary examples from astrophotography are analysed and reconstructed using text-to-image models. From the comparative analysis, computational photorealism emerges as a (...) modified term that recognizes the relationship between photography and text-to-image models without conflating their ontological and epistemological differences.

Background To characterize patients dying in a community hospital with or without attempting cardiopulmonary resuscitation and to describe patient involvement in, documentation of, and compliance with decisions on resuscitation. Methods All patients who died in Kalmar County Hospital during January 1, 2016 until December 31, 2016 were included. All information from the patients’ electronic chart was analysed. Results Of 660 patients female), 30 were pronounced dead in the emergency department after out-of-hospital CPR. Of the remaining 630 patients a DNAR order (...) had been documented in 558 patients. Seventy had no DNAR order and 2 an explicit order to do CPR. In 43 of these 70 patients CPR was unsuccessfully attempted while the remaining 27 patients died without attempting CPR. In 2 of 558 patients CPR was attempted despite a DNAR order in place. In 412 patients the DNAR order had not been discussed with neither patient nor family/friends. Moreover, in 75 cases neither patient nor family/friends were even informed about the decision on code status. Conclusions In general, a large percentage of patients in our study had a DNAR order in place. However, 27 patients died without CPR attempt or DNAR order. DNAR orders had not been discussed with the patient/surrogate in almost three fourths of the patients. Further work has to be done to elucidate the barriers to discussions of CPR decisions with the patient. (shrink)

Brian Epstein has argued (in The Ant Trap and ‘Anchoring versus grounding’) that social kinds ‘export’ across worlds. Although the conditions for war criminality are not ‘fixed’ in the Empire, for instance, Darth Vader is a war criminal there. And, according to Epstein, an account of social construction should imply that he is. Ultimately, he argues that ‘grounding-only’ accounts of social construction – like those proposed by Jonathan Schaffer and Aaron Griffith – imply that social kinds do not export across (...) worlds. As a result, he argues that we need more than grounding; in particular, we need both grounding and what he calls ‘anchoring’ to account for it. In this paper, I argue that, once we draw a distinction between what I call ‘thick’ and ‘thin’ social kinds, Epstein’s argument is either invalid or irrelevant. (shrink)

In this contribution we will approach language and images in different modalities: speech and face, anticipated and imagined movements, illusions on the sound by the image. It will be the opportunity for us to revisit the Gestalt concepts which were considered obsolete since structuralism in Humanities. As instantiated by Gilbert Durand in The Anthropological Structures of the Imaginary (1999, French 1st ed. 1960), we shall recall that Gestalt is not—even implicitly—an exclusively static approach to cognition. On the contrary we will (...) emphasize that forms can emerge from movements and stabilize in memory, thence morphology. And for speech, we will consider phonology as the stabilized outcome from audible and visible gestures of the mouth—caught in the time-course of a flow of some four in six syllables by second—via the perception of motor coordinations: which is necessary to master the most common expression of language between humans. We will adopt here also for the perceptual flows of spoken language, Multimodal Scene Analysis, the ongoing legacy of Gestalt Theory, including one of our main research topics: the gestural expression of the face and the hand for Deaf people, who practise as an augment French LPC (Langue française Parlée Complétée), adapted in 1967 from Cued Speech by its originator Dr Richard Cornett.

The haploid male germ cell differentiation program controls essential steps of male gametogenesis and relies partly on a significant number of sex chromosome‐linked genes. These genes need to escape chromosome‐wide transcriptional repression of sex chromosomes, which occurs during meiosis and is largely maintained in post‐meiotic cells. A newly discovered histone lysine modification, crotonylation (Kcr), marks X/Y‐linked genes that are active in post‐meiotic male germ cells. Histone Kcr, by conferring resistance to transcriptional repressors, could be a dominant element in maintaining these (...) genes active in the globally repressive environment of haploid cell sex chromosomes. Furthermore, the same mark was found associated with post‐meiotically activated genes on autosomes. Histone Kcr therefore appears to be an indicator of the male haploid cell gene expression program and a notable element of genome programming in the post‐meiotic phases of spermatogenesis. (shrink)

Chora – le «cratère à mélanger» maternel, vannant et secouant de Platon – remplit «l’écart explicatif» entre les paradigmes formels «intelligibles et toujours existants» (48E5) et un monde encosmique «généré et visible». Proclus traite la gamme polysémique des termes utilisés par Platon pour chôra : hypodochê (réceptacle), kratêr (cratère à mélanger), etc., comme désignant des forces actives dans un univers où la sympathie cosmique règne, à partir des plus élevées, jusqu’aux plus basses manifestations de l’ «Un» transcendant. L’univers proclusien est (...) un «hénothéisme», dans lequel une «unité» dominante surgit sur la totalité de l’Être et du Devenir. Chôra permet à la fois au monde immatériel et au monde matériel de recevoir, de manière appropriée à chacun, les mêmes dons transcendants que leurs homologues intellectifs‑intelligibles superieurs. Aucun niveau de la réalité n’est dépourvu de cette donation. La réceptivité (hypodochê), indéterminée, mais toujours active, est présente à tous les niveaux. L’âme reçoit l’Intellect, la temporalité reçoit le temps monadique, la matière reçoit la structure géométrique polyédrique, etc. Chôra n’est pas l’equivalent de la matière, mais permet à la matière d’être imprimée par des paradigmes formels. Dans son rôle de «cratère à mélanger», elle protège la matière de sa potentielle itérabilité et dissolution infinie. Dans l’univers proclusien, le Bien atteint la dernière et la plus extrême de ses limites, il est espace et lieu, recevant à la fois l’expansivité et une capacité à donner place à la forme pour qu’elle puisse s’imposer à la matière. Après tout, les dons lui sont accordés depuis la plus haute hypostase, celle de la Limite et de l’Illimité, premier niveau après l’Un lui‑même. Vitale pour la création, la Chôra est alors la «mère» de tout. Il n’est donc pas étonnant que, comme nous le dit Proclus, la chôra soit, en fait, la déesse Rhéa. En hommage à la littérature révélatrice antique, comme les Oracles chaldaïques, Homère et Hésiode, Proclus fournit une élucidation non seulement philosophique, mais aussi théologique, de la chôra. À la différence de Platon, il théologise la Physique. (shrink)

Through a fieldwork study of the practice of methadone substitution at a French addiction clinic, the classic ‘theory of action’ is criticized and an alternative one proposed. A sketch of the debates among French drug specialists, drug users and legislators shows the pertinence for these practitioners of such a theoretical question; further, the ethnographic data suggest that they can be seen as actually trying out an alternative to this ‘theory of action’.

Patočka has never developed the political and historical concept of dissidence. But trying to sketch its phenomenological foundation in the writings of the Czech philosopher, who experienced human liberty as an act of dissidence, could be an original way in qualifying his alternative idea of the modern subjectivity in phenomenology: between finitude and autonomy. The first part of the article presents the radical criticism aimed by Patočka to the transcendental subjectivism of Husserl, and thinks the requirement of a split between (...) autofoundation and autonomy. Then, it is analysed the articulation between the movement of life and the movement of existence, in which lies the very idea of dissidence. In a third and final part, one shows to what extent the dissident subjectivity fully reveals itself in the political life. (shrink)

This paper draws on an in-depth phenomenological analysis of some interviews taken from volunteers, inviting them to reflect on their lived experiences of meaningfulness in the context of volunteering and citizenship. It is found that while some testimonies reinforce the standard conceptions of meaningfulness, other testimonies vary from it. The main challenge of this contribution consists in phenomenologically describing this alternative picture of meaningfulness, depicted as the event of wit(h)nessing. In a final part, the authors consider how volunteering is at (...) times especially prone to further experiences of wit(h)nessing. (shrink)

In this comment on Johan Von Essen’s contribution on the meaning of volunteering we make some remarks about Von Essen’s starting point, which reveals a particular perspective on meaningfulness, namely that people perceive reality as meaningful when their actions and the things they encounter are part of a meaningful whole. By introducing another perspective on meaningfulness, namely that the shattering of a meaningful whole is full of meaning, we question if practices of volunteering which occur in face-to-face situations—and thus outside (...) the public realm—can be fully captured by the five predicates that make up the phenomenological structure of volunteering.

Peter Singer est un philosophe utilitariste de renommée internationale. Il est titulaire de la chaire de bioéthique à Princeton. Depuis une trentaine d’années il s’intéresse à des questions éthiques telles que le statut moral des animaux, la bioéthique, l’environnement, et la manière de lutter contre la pauvreté dans le monde. C’est à cette question qu’il consacre son dernier ouvrage, paru en France en 2009 : Sauver une vie. Agir maintenant pour éradiquer la pauvreté.Sauver une vie n’est pas ..

Dans un régime comme celui de la République populaire de Chine, où prévaut la suprématie d’un Parti-État unique, la politique et le politique constituent, a fortiori plus qu’ailleurs, la chasse gardée de l’élite dirigeante du pays, à savoir les cadres du Parti communiste. Cet article tente de saisir qui sont les élites politiques aux commandes de la Chine d’aujourd’hui à travers l’analyse du modus operandi de l’École des cadres du Parti de Shanghai. L’étude de cette institution, qui participe à la (...) régulation de la circulation des élites et constitue l’un des lieux privilégiés de la transmission et de l’exercice du pouvoir, permet, par-delà son propre fonctionnement, d’éclairer la nature et le devenir même du régime. S’il apparaît que les forces modernisatrices, en assimilant davantage l’École du Parti à un institut d’administration publique, œuvrent à la professionnalisation du métier de cadre, c’est également et avant tout afin de mieux perpétuer l’hégémonie du Parti-État unique.In a regime where the one Party-State rule still prevails, as is the case in the People’s Republic of China, the polity and politics constitute – here more than anywhere else – the private ground of the country’s ruling elite, i.e. the cadres of the Communist Party. This article attempts to grasp who the political elites in control of contemporary China are, by analyzing the modus operandi of the Shanghai Party School for Cadres. The study of an institution that takes part in the circulation of the elites and hence constitutes one of the privileged playing fields for the transmission and the exercise of power, allows, beyond the understanding of its own working, to shed light on the very nature and evolution of the regime. If the modernizing forces appear to work towards the professionalization of the cadres’ craft by equating the Party School to an institute of public administration, they ultimately do so in order to better perpetuate the supremacy ofthe one-Party system.

Soul is the self-moving, self-constituting entity linking the transcendent with the immanent. Proclus distinguishes many types of souls. This chapter concentrates on the World Soul and the rational human soul. The World Soul infuses the sensible, temporal, divided, and material cosmos with unity and Forms ultimately deriving from the One and Intelligible Being, in a manner reminiscent of human phantasia. The mathematical psychology of the Timaeus is explained as referring to the Soul’s activity, rather than its essence. Concerning the human (...) soul, with its eternal essence and temporal activity, the authors concentrate on the function and nature of the many ‘vehicles’, assisting the soul’s descent and, in a different manner, its ascent.

These hominins used their ability to choose freely to distance themselves from God at some point in history. These stories follow the Augustinian heritage. Some like contend that neither paleoanthropological nor genetic data lend credence to the existence of a superhuman society. This analysis shed light on the variety of religious and scientific writings. A detailed summary would be outside the purview of the study. Because the terms "science" and "religion" are so broad, the literature has split into many areas (...) of "science-engaged theology," where a particular scientific claim or subfield is examined in light of a particular theological argument. Asking whether Christian eschatology is consistent with scientific claims about cultural evolution or the cosmic fate of the cosmos would be a more pertinent question than whether Christianity is consistent with Science. The range of subjects that Science and religion can address grows as their respective fields become more global and expansive. All the religious philosophies say that this world will end one day, and there will be a day of judgment after it. Same in the Case of Science, nowadays metaphysics proves that this universe will end a day after some time. If there will be an end of the world, there will also be a day of judgment. So, aspects of the end of the world and the Day of Judgment have also been proved by scientific studies and religious philosophies. (shrink)

Background: Autonomy is a central concept in both bioethics and rehabilitation. Bioethics has emphasized autonomy as self-governance and its application in treatment decision-making. In addition to discussing decisional autonomy, rehabilitation also focuses on autonomy as functional independence. In practice, responding to patients with diminished autonomy is an important component of rehabilitation care, but also gives rise to tensions and challenges. Our objective was to better understand the complex and distinctive ways that autonomy is understood and upheld in the context of (...) rehabilitation care by reviewing how autonomy is discussed in the rehabilitation literature. Methods: We conducted a scoping review addressing issues of autonomy in the context of mental and physical rehabilitation. Our process followed three sequential steps. We extracted and analyzed bibliometric information. We then examined how autonomy was defined and conceptualized. Finally, we examined how the articles discussed the roles of rehabilitation health professionals in responding to patient autonomy. Findings: The articles include 16 empirical reports, 17 case studies and 30 theoretical papers. The most common conceptual accounts of autonomy drew upon principlism, rights-based and legal analyses, and relational/social approaches. We identified four broad approaches for responding to patient autonomy: supporting, promoting, respecting and advocating. Conclusion: This review helps clarify some of the ambiguities and conceptual distinctions underlying discussions and practices related to autonomy in rehabilitation. It also draws attention to a wide range of activities that health professionals can undertake with the goal of supporting, promoting, respecting and advocating for patient autonomy in rehabilitation care.

Background/ObjectiveSeveral studies have examined the impact of Parkinson’s disease on the quality of couples’ relationships. To date, few studies have explored how couples experience their relationship dynamic by taking into account the disease stage. The objectives of this study were to understand the experience of each partner and to study the mechanisms that underlie their couple organization in the advanced stage of PD.MethodsSemistructured individual interviews conducted with fifteen patients and their partners were the subject of a dyadic interpretative phenomenological analysis.ResultsThree (...) themes were identified from the analysis: the first, “A Closeness That Separates,” allows the identification of different patterns of interactions that lead to emotional distancing between the partners; the second, “The Adversity Is Not Unbearable, But Going It Alone Would Be,” emphasizes the importance of how the assisting partner provides support; and the third, “Be Prepared for Anything and Facing an Uncertain Future,” reveals the extent and modes of the dyadic regulation of the emotions linked to what the future may hold.ConclusionPsychological support is important to help couples express both their feelings and their respective needs in the evolving context of PD.

Dans son ouvrage La libération animale, Peter Singer développe trois grandes idées : le principe d'égale considération des intérêts, le rejet du spécisme et la nécessité de mettre un terme à certains types d'exploitation des animaux, notamment ceux qui ont trait à la recherche et à l'élevage industriel. Cette oeuvre phare a connu un retentissement immense, à tel point que sa publication, en 1975, a été présentée comme le moment clef dans l'émergence du mouvement éponyme. Cependant, le mouvement de libération (...) animale ne saurait se réduire à la seule pensée singerienne. Ce mouvement extrêmement protéiforme a fait l'objet de débats intenses à l'interne, entre les défenseurs des animaux eux-mêmes qui privilégient des approches diverses, comme à l'externe, entre ceux qui défendent le statu quo ou contestent les arguments animalistes. L'objet de ce recueil est de revenir sur le lien entre le mouvement de libération animale et les théories de Peter Singer qui, à tort ou à raison, en est perçu comme le père fondateur. Comment l'éthique animale de l'auteur a-t-elle été accueillie depuis la publication de La libération animale, et comment a-t-elle évolué? Quelle place la doctrine utilitariste occupe-t-elle dans le travail de Singer et dans les débats qu'il a engendrés? C'est en effet dans cette doctrine parente que résident les écueils auxquels s'est heurté le travail de l'auteur. C'est aussi là que son système a trouvé sa force et sa simplicité caractéristiques. C'est aussi, semble-t-il, ce qui fait la fécondité de ses idées. (shrink)

The idea that mythos and logos are incompatible, and that truth is a product of scientific and dialectical thinking, was certainly disproven by later Platonic philosophers. Deploying the works of Hesiod and Homer, Homeric Hymns and other such literature, they considered myth a valuable and significant augment to philosophical discourse. Plato’s denigration of myth gave his followers an incentive to read myth as allegory. The Stoics and first-century philosophers such as Philo, treated allegory as a legitimate interpretive strategy. The Middle (...) Platonists incorporated myth, for example, deifying the Monad and Dyad, as did 2nd century Platonists. Plutarch’s Isis and Osiris, for example, equates Isis and Osiris with form and matter: the god sows in matter logoi from himself. Porphyry’s allegorizing of Plato’s Cave of the Nymphs is another example. Plotinus is a strong influence on how the late Neoplatonists regarded myth. This paper argues that these philosophers’ use of allegory prepared the way for the Neoplatonists treatment of myth as inspired symbolism. Proclus and Syrianus, as reported by Hermias, did something more extreme by using mythology to construct inspired symbolic argument. Mythos becomes another type of logos, a vehicle for representing the invisible world of being, another kind of truth that can even serve a function in anagogic ascent. (shrink)

Cette note de recherche prend pour point de départ un certain nombre d’observations empiriques sur les pratiques d’écritures relatives à la « rédaction web ». Son ancrage est celui de l’analyse du discours, envisagée comme discipline interprétative et lecture critique des énoncés mais aussi comme démarche susceptible d’apporter sa contribution à une didactique de l’écrit. Nous y livrons quelques premiers éléments de réflexion pour la caractérisation discursive des textes issus de la rédaction web, prenant en compte pour cela à la (...) fois la composante discursive de ces productions et les discours construisant la rédaction web comme pratique d’écriture. A partir de deux exemples, nous montrons que les normes dominantes de la rédaction web, liées notamment aux contraintes du support et à des enjeux économiques, sont diversement prises en compte suivant la sphère d'activité où sont produits les textes.

This paper examines Irish campaigns for condom access in the early 1990s. Against the backdrop of the AIDS crisis, activists campaigned against a law which would not allow condoms to be sold from ordinary commercial spaces or vending machines, and restricted sale to young people. Advancing a conception of ‘transformative illegality’, we show that illegal action was fundamental to the eventual legalisation of commercial condom sale. However, rather than foregrounding illegal condom sale as a mode of spectacular direct action, we (...) show that tactics of illegal sale in the 1990s built on 20 years of everyday illegal sale within the Irish family planning movement. Everyday illegal sale was a long-term world-making practice, which gradually transformed condoms’ legal meanings, eventually enabling new forms of provocative and irreverent protest. Condoms ‘became legal’ when the state recognised modes of condom sale, gradually built up over many years and publicised in direct action and in the courts. (shrink)

"Reading with John Clare argues that poetry and its repression lies at the heart of biopolitical thinking. By rereading the emergence of biopolitics and focusing on the exemplary case of John Clare, it renews our understanding of the relation between aesthetics and politics from romanticism to the present"--.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Rhetoric of Romantic ProphecySara GuyerThe Rhetoric of Romantic Prophecy. Ian BalfourStanford: Stanford University Press, 2002. Pp. 368. $70.00, cloth; $29.95, paperback.Not insignificantly, Walter Benjamin and Maurice Blanchot are the first two names to appear in Ian Balfour's excellent study The Rhetoric of Romantic Prophecy. Benjamin and Blanchot are authors of two of the most influential essays on romanticism, essays that, it just so happens, Ian Balfour is (...) responsible for introducing to an English-reading audience. 1 Thus, The Rhetoric of Romantic Prophecy is not only a long awaited, prize-winning book by a major theorist of romanticism, it is also a book written by the first English translator of Benjamin's and Blanchot's essays. Both Blanchot's "The Athenaeum" and Benjamin's "On the Concept of Criticism in German Romanticism" expose the incompletion of the romantic project and unsettle the relation between the past and the present. They also provide a context for understanding the kind of book that Ian Balfour has written. Like its eminent predecessors, this book focuses on local phenomena, yet its force far exceeds the field that it so thoughtfully treats. In it, Balfour shows how a turn to the past (to a set of historical texts) has the effect of unsettling the present, and he argues that an apparent turn to the future (prophecy) has as its issue the present.The book's introduction, entitled "The Call of Prophecy and the Future (After Benjamin)," alerts us to the fact that Benjamin and Blanchot, who have written extensively on language, also have written compellingly on the prophetic. While the prophetic today most often seems to signify religion's naive or violent claims on the future (and by implication on the present), in Benjamin's and Blanchot's work—and in Balfour's work—"the prophetic" (by which Balfour means not a genre, but a "mode") poses problems of referentiality and interpretation. Benjamin's treatment of messianism and allegory in the "Theses on the Philosophy of History" offers Balfour a clear framework for undertaking this examination. And, in style and approach, Benjamin is the thinker with whom Balfour has the closest kinship. Like Benjamin's The Origin of German Tragic Drama, Balfour's The Rhetoric of Romantic Prophecy is a historical study that is not historicist, that is, it does not aim to account for a historical phenomenon, but is a philosophical and rhetorical investigation into language.However, it is Blanchot's brief essay "Prophetic Speech"—a review of André Neher's L'essence du prophétisme—that informs Balfour's thinking about the prophetic. Indeed, Balfour's book can be read as a meditation on the rhetorical implications of Blanchot's suggestion that: [End Page 257]Prophetic speech announces an impossible future, or makes the future it announces, because it announces it, something impossible, a future one would not know how to live and that must upset all the sure givens of existence. When speech becomes prophetic it is not the future that is given, it is the present that is taken away, and with it any possibility of a firm, stable, lasting presence. 2With this passage, Blanchot not only recasts the conventional account of prophecy (and, implicitly, the symbolic reading upon which prophecy relies), but also shows that if prophecy turns the future into a referent—and hence becomes history—the present is lost. Balfour's transfer of Blanchot's account of the prophetic to romanticism is broadly explained by the debates within romanticism (and contemporary criticism of romanticism) about referentiality and the primacy of symbol over allegory, debates that today are most well-known to non-romanticists through Paul de Man's "The Rhetoric of Temporality."Balfour offers a lucid account of his project—and its relation to history and historicist criticism—when he explains:If there is a historical force to the analysis here, it lies not in the attempt to show how representative these texts were of some larger, pervasive phenomenon—although they sometimes are—but rather to mark what was possible to be thought and done at a given moment. More than that, the analysis implicitly and sometimes explicitly confronts... (shrink)

Contre toute attente, si l’on adopte la perspective d’un « augustinisme politique », les concepts de « cité céleste » et de « cité terrestre » ne font justement l’objet d’aucune interprétation politique dans les milieux intellectuels franciscains du xiii e siècle. Jérusalem et Babylone représentent d’abord des manières d’être et de vivre ensemble, et font donc l’objet d’une lecture spirituelle. Les frères mineurs n’en ont pas moins essayé d’esquisser, à l’écart des deux cités mystiques, un espace intermédiaire, cité des (...) hommes, qui pouvait prendre la forme d’une république chrétienne universelle (Roger Bacon), d’une théocratie juridique dont le pape est le sommet terrestre (Bonaventure), ou plus radicalement d’une anticipation de la Jérusalem céleste.

Adaptive phenotypic plasticity allows organisms to cope with environmental variability, and yet, despite its adaptive significance, phenotypic plasticity is neither ubiquitous nor infinite. In this review, we merge developmental and population genetic perspectives to explore costs and limits on the evolution of plasticity. Specifically, we focus on the role of modularity in developmental genetic networks as a mechanism underlying phenotypic plasticity, and apply to it lessons learned from population genetic theory on the interplay between relaxed selection and mutation accumulation. We (...) argue that the environmental specificity of gene expression and the associated reduction in pleiotropic constraints drive a fundamental tradeoff between the range of plasticity that can be accommodated and mutation accumulation in alternative developmental networks. This tradeoff has broad implications for understanding the origin and maintenance of plasticity and may contribute to a better understanding of the role of plasticity in the origin, diversification, and loss of phenotypic diversity.

After reviewing the literature on current knowledge about consciousness in humans, we present a state-of-the art discussion on consciousness and related key concepts in animals. Obviously much fewer publications are available on non-human species than on humans, most of them relating to laboratory or wild animal species, and only few to livestock species. Human consciousness is by definition subjective and private. Animal consciousness is usually assessed through behavioural performance. Behaviour involves a wide array of cognitive processes that have to be (...) assessed separately using specific experimental protocols. Accordingly, several processes indicative of the presence of consciousness are discussed: perception and cognition, awareness of the bodily-self, self-related knowledge of the environment (including social environment). When available, specific examples are given in livestock species. Next, we review the existing evidence regarding neuronal correlates of consciousness, and emphasize the difficulty of linking aspects of consciousness to specific neural structures across the phyla because high-level cognitive abilities may have evolved independently along evolution. Several mammalian brain structures (cortex and midbrain) are involved in the manifestations of consciousness, while the equivalent functional structures for birds and fishes would likely be the pallium/tectum and midbrain. Caution is required before excluding consciousness in species not having the same brain structures as the mammalian ones as different neural architectures may mediate comparable processes. Finally, specific neurophysiological mechanisms appear to be strongly linked to the emergence of consciousness, namely neural synchrony and neural feedback. Considering the limited amount of data available and the few animal species studied so far, we conclude that different manifestations of consciousness can be observed in animals but that further refinement is still needed to characterize their level and content in each species. Further research is required to clarify these issues, especially in livestock species. (shrink)

Paul Henri Thiry d'Holbach financed and contributed to Diderot's Encyclopedia. He hosted many of Europe's best minds in the eighteenth century. The first half of this chapter describes these roles with a focus on atheism in Enlightenment France. Holbach was also a prolific writer. The second half of this chapter defends an interpretation of his atheism. Holbach held that God does not exist and that the knowledge of this fact is a great benefit to those who come to have it.
