Because theories of visual perception have traditionally concentrated on form, artists have generally dealt with the problem of color through their own observation and intuition. In _Color Harmonies,_ Augusto Garau systematically investigates the role of both color and form in visual perception and presents an original theory of the aesthetic relations among colors. Garau, a painter who teaches the psychology of form, pays particular attention to the way colors behave when organized in patterns. His theory of color combination addresses two (...) principal compositional elements: the relations between figure and ground and the phenomenon of transparency. Garau meticulously analyzes the use of color in paintings by masters such as Cézanne, Picasso, and Matisse to show how his theory applies to actual works of art. Containing many full-color examples, his introduction to the workings of color relations is of great practical use to art historians and critics, artists, interior decorators, fashion and set designers, and anyone who works with color to display information or convey emotions. "In an area of the psychology of art where reliable guidance is still so hard to come by, [Garau's] well-supported contributions to the theory of color composition ought to be welcomed by practitioners and scholars alike."—from the Foreword by Rudolf Arnheim.

The article addresses the question of how should scientific peers revise their beliefs (if at all) upon recognized disagreement. After presenting the basics of peer disagreement in sections 1 and 2, we focus, in section 3, on a concrete case of scientific disagreement, to wit, the dispute over the evidential status of randomized control trials in medical practice. The examination of this case motivates the idea that some scientific disagreements permit a steadfast reaction. In section 4, we support this conclusion (...) by providing a normative argument in the same direction; if we are correct, typical reasons for conciliation are absent in this kind of scientific disagreements.

Après avoir identifié quelques-uns des multiples biais intellectuels qui obèrent trop souvent l’analyse de la réalité économique africaine, cette introduction précise la perspective de ce numéro. Il tente de définir l’esprit d’une économie politique lucide appliquée aux pays d’Afrique, avant de présenter brièvement les articles du dossier.

Trichromacy may result from an adaptation to the regularities in terrestrial illumination. However, we suggest that a complete characterization of the challenges faced by colour perception must include changes in surface surround and illuminant changes due to inter-reflections between surfaces in cluttered scenes. Furthermore, our trichromatic system may have evolved to allow the detection of brownish-reddish edibles against greenish backgrounds. [Shepard].

The metaverse is the extension of this virtual world in which our avatars and other holograms will socialize. Should we speak of incarnation when it is virtual beings that represent us rather than physical bodies?

La sous-traitance peut être analysée comme une forme contemporaine de l’extraction du surtravail qui met en œuvre le principe de la dépendance économique au niveau des relations inter-entreprises. Elle contribue à contourner le droit du travail et à transférer un ensemble de risques des employeurs vers les travailleurs. À travers les cas du secteur forestier en Afrique du Sud, du secteur de la construction en Australie et d’une analyse intersectorielle en France, ce texte montre que la sous-traitance s’est diffusée très (...) largement depuis trente ans et contribue à redéfinir en profondeur l’organisation globale des rapports de production dans les économies capitalistes.

Une classe capitaliste nationale peut-elle émerger dans les pays africains nouvellement indépendants? Débattue il y a quarante ans à propos du Kenya, la question se pose également pour l’Éthiopie des trois dernières décennies. Bien que ce pays n’ait jamais été colonisé, son passage il y a trente ans d’un régime militaire à un État démocratique et développeur a marqué un tournant comparable à celui des pays africains anciennement colonisés. Cette transition politique promettait d’accorder un rôle économique plus important au secteur (...) privé national, jusqu’alors très limité. Cette transition s’est toutefois accompagnée d’importantes contradictions en matière de propriété du capital, compte tenu de la centralisation de la politique industrielle par l’État éthiopien. Cet article analyse les tentatives de l’État éthiopien de stimuler la formation d’une classe capitaliste productive et autochtone, dans le secteur des métaux et de l’ingénierie, au cours de la dernière décennie.

Les dynamiques de classe du changement agraire en Afrique ont fait l’objet de débats importants. Dans son ouvrage de référence, Femmes, greniers et capitaux, Meillassoux prédisait en 1975 la cannibalisation de la paysannerie, avec la domination croissante des relations capitalistes dans les campagnes. Pourtant, près d’un demi-siècle plus tard, la paysannerie reste une construction sociale, économique et politique pertinente. En s’appuyant sur le cas du Mozambique, cet article explore les significations contradictoires de la paysannerie dans le capitalisme contemporain. La première (...) section retrace la création du paysan-prolétaire en Afrique australe, en s’appuyant sur les travaux de Meillassoux sur la « communauté domestique ». La deuxième partie explore les différentes manières dont les camponeses improvisent leur subsistance à travers trois cas. L’article conclut que la paysannerie incarne un ensemble contradictoire de significations qui reflètent les processus de production de marchandises plutôt qu’un passé précapitaliste. (shrink)

The planning/control distinction is an important tool in the study of sensorimotor transformations. However, published data from our laboratories suggest that, contrary to what is predicted by the proposed model, (1) structures in the superior parietal lobe of both monkeys and humans can be involved in movement planning; and (2) fast pointing actions can be immune to visual illusions even if they are performed without visual feedback. The planning–control model as proposed by Glover is almost certainly too schematic.

In a series of televised interviews in spring 2022, Bruno Latour explained, in clear and straightforward terms, how humans have changed the planet and why environmental disasters are an intrinsic part of modern life. We have now come to realize that all life depends on a thin skin of our planet that is only few kilometres thick - what scientists call the 'critical zone'. Our capacity to continue to live on a planet we are transforming is now at risk (...) and if we wish to survive as a species, we must put an end to the mechanisms of destruction, rethink our connection to living beings and face head-on the confrontation between the extractivists who are exploiting the Earth's resources and the ecologists. This poignant reflection on the greatest challenge of our time is also an opportunity for Latour to explain the underlying thread that guided his work throughout his career, from his pathbreaking research on the social construction of scientific knowledge to his last writings on the Anthropocene.

Une envie de transmettre, d'expliquer. De s'expliquer aussi. Sur la cohérence d'une pensée que l'apparente dispersion et variété des sujets qu'il a abordés avait, en partie, masquée. Bruno Latour s'est livré à cette série d'entretiens avec une simplicité, une jubilation et une puissance qui n'adviennent que dans les moments où l'on sait que la vie, et notamment celle de l'esprit, se condense. Un apaisement lié au sentiment d'urgence, une immanence indissociable de l'imminence et de la nécessité à tout concentrer, (...) résumer, déployer. Un souci de clarté, un plaisir de la conversation, un art de la performance. Comme si tout s'éclaircissait alors que la fin approchait"--Page 4 of cover. (shrink)

In this article, we present findings from a participatory action research program in France on the exercise of human rights and supported and substitute decision-making, inspired by the United Nations Convention on the Rights of Persons with Disabilities (“CRPD”). Bringing together persons with the lived experience of disability, academics, and health and social care and support professionals, the project used the method of “experience-based construction of public problem” to transform experience into collective expertise. This enabled the exploration of support that (...) persons in vulnerable situations, whose capacity to exercise their human rights has weakened, need to make decisions in their lives and participate meaningfully in public debate. The relationship between the awareness of rights and exercise of rights is discussed. We argue for the need to balance out the positions of different contributors in participatory action research, in a reasoned manner, by recognizing the scientific and citizen-based participation of all partners.

Dans cet entretien, Nicola Manghi invite Donna Haraway à revisiter les nombreuses années de proximité et d’échanges qui ont vu son travail croiser celui de Bruno Latour. Des études féministes au catholicisme, des guerres des sciences à la lutte des classes, c’est une période et une mouvance importantes de la pensée contemporaine qui se trouvent ainsi revisitées, avec en prime quelques considérations de Donna Haraway sur ses pratiques de recherche et d’écriture, ainsi que sur sa conception de Gaïa.

Las reflexiones que conforman el presente artículo intentan brindar un aporte a la cuestión de la naturaleza y de la problemática medioambiental desde el punto de vista de lo que denominaremos una filosofía del suelo. Se emprenderá dicha tarea a través de los planteos de una serie de autores y autoras pertenecientes a la contemporaneidad filosófica, que se han preocupado, en distinta medida y de modos muy diferentes, por la problemática de la tierra o el suelo: Donna Haraway, Tim Ingold (...) y Bruno Latour. Para esto, nos serviremos de una serie de elementos que extraeremos de la experiencia visual y táctil de las Líneas de Nazca, legado de nuestro pasado amerindio en el desierto peruano. El trabajo se dividirá en tres partes, dedicada cada una de ellas a explicitar ciertas reflexiones de los autores que puedan asociarse a una filosofía como la que pretendemos mentar. El enfoque priorizará los entrelazos entre los mismos y el desarrollo de elementos que nos permitan un entrecruzamiento de sus respectivas teorías. (shrink)

This article situates actor-network theory in the history of evolutionary anthropology. In the 1980s, this attempt at explaining the social through the mediation of nonhumans received important impulses from Bruno Latour’s conversations with primatologist Shirley Strum. In a re-articulation of social evolutionism, they proposed that the utilization of objects distinguished humans from baboons and that the use of a growing number of objects set industrialized human populations apart from hunter-gatherers, enabling the formation of larger collectives. While Strum’s and Latour’s (...) early work presented baboons as almost human and suggested that we moderns had never been modern, the Anthropocene has reawakened curiosity about the original question of anthropology: how do modern humans, including modern scientists, differ from premoderns and animals? This 18th-century question is gaining new significance and urgency as we recognize our transmutation into a super-dominant species. But the answer might not lie solely in the use of more objects.

Bruno Latour reconnaît l’influence de Gilbert Simondon sur son oeuvre, en particulier quant à sa compréhension de la technique. Latour semble ainsi réaliser en grande partie le programme de « non-anthropologie » de Simondon. Mais une apparente contradiction existe dans le traitement de l’énonciation par Latour : sa compréhension de la matérialité et des modes d’existence semble prendre le détour de la sémiotique. Cela a mené certains critiques à mettre en doute son approche de la matérialité. Toutefois, vue à (...) travers la lentille de l’influence que Simondon a eue sur Latour, il est possible de relire la théorie latourienne de l’énonciation en comprenant la communication comme passage de l’action d’un être à l’autre, et la signification de cette action comme résultat de sa participation à un processus de constitution des êtres. Latour est donc résolument un penseur du décentrement de l’humain.Bruno Latour recognizes the influence of Gilbert Simondon on his work, especially with respect to his understanding of technique. Latour appears, in that sense, to actualize a large proportion of Simondon’s “non-anthropology”. Yet, what appears to be a contradiction remains in his treatment of enunciation: indeed, his understanding of materiality seems to take the detour of semiotics. This has led some critics to question his approach to materiality. However, seen through the lens of Simondon’s influence on him, it is possible to revisit Latour’s theory of enunciation and to understand communication as the passage of action from one being to the next, and signification as the outcome of action’s participation to the constitution process of a being. This way, Latour is a thinker resolutely committed to de-centering the focus of research away from human beings. (shrink)

Translator's introduction : At the end of July 2014 there was a week-long workshop held at the Ecole des Mines in Paris, Bruno Latour's former work-place. This was a final workshop, convened by Latour's project, An Inquiry into Modes of Existence, which was not only a book, but a website that was an experiment in interactive metaphysics that had been going on for four years. About 30 participants gathered to workshop and rewrite some key contested areas that had been (...) challenged on the site with discussions and counter-examples. One of the round tables working away during the week, occasionally with changes in personnel, was on Nature. Their job (like the other round tables on Politics, Diplomacy, Religion and Economics) was to ‘reboot’ or reinstitute a concept close to the heart of the Moderns. The assumption was that the traditional concept of nature, as developed through modern European history, would no longer be adequate to a future beset by environmental crises. The main people working on a draft were Didier Debaise, Pablo Jensen, Pierre Montebello, Nicolas Prignot, Isabelle Stengers and Aline Wiame. When they finished the draft, I translated it and it was presented, in French and English, in a final two-day public session at Science Po, to a group of seven international scholars designated as “chargés d'affaires,” or “diplomats from the future” whose job was to assess the results of our labours in terms of how they might be met by Gaia, the ur-representative of future planetary crises. The text, originally under the title of Our “Nature,” was as follows. [Stephen Muecke]. (shrink)

Dans un contexte de compréhension de l’être humain en tant que créé à l’image et à la ressemblance divine, Nicolas de Cues a considéré que la vision et l’union avec l’Absolu conduit, d’une part, au bonheur, et implique aussi, d’autre part, l’expression de la plus grande liberté que puisse atteindre l’humain, c’est-à-dire la pleine possession de soi. Cette conviction se présente dans son œuvre, le De visione Dei, dans une ambiance mesurée par l’attitude de la personne en prière, qui (...) s’adresse à Dieu dans la recherche de soi-même, et dans l’aspiration à accéder à ce qui est sciemment inaccessible. À la fin de la Renaissance, Giordano Bruno est l’auteur qui marquera indiscutablement le tournant anthropologique dans le sens d’une subjectivité ne prétendant plus à une union avec l’Absolu, mais qui se retourne vers elle-même. Cela se produit dans un système dans lequel l’être humain et le monde s’auto-impliquent dans une totalité dynamique qui ne laisse pas de place à un Absolu transcendant. (shrink)

À l’origine de cet ouvrage, il y a le postulat que la conception historique de la laïcité « à la française » est un héritage problématique plus que dogmatique. C’est-à-dire un héritage, comme l’évoque la conclusion, « qui ne saurait être envisagé comme une question à clore, mais bien plutôt comme un champ susceptible de reconfiguration perpétuelle ». La spécificité de cet ouvrage dans ce champ repose alors quant à elle sur deux points. Il s’agit d’abord de prendre le temps (...) du recul, du suspen.. (shrink)

The belief that the spirits of the dead can return to haunt the living exists either as a tenet or as a marginal conviction in all civilizations, whether ancient or modern. More often than not, the dead do not return to reunite the living with their loved ones but rather to lead them into some dreadful snare, entrapping them with disastrous consequences. To be sure, all the departed may return, but some are predestined to haunt: the dead who have been (...) shamed during their lifetime or those who took unspeakable secrets to the grave. From the brucolacs, the errant sprits of outcasts in ancient Greece, to the ghost of Hamlet’s vengeful father, and on down to the rapping spirits of modern times, the theme of the dead—who, having suffered repression by their family or society, cannot enjoy, even in death, a state of authenticity—appears to be omnipresent on the fringes of religions and, failing that, in rational systems. It is a fact that the “phantom,” whatever its form, is nothing but an invention of the living. Yes, an invention in the sense that the phantom is meant to objectify, even if under the guise of individual or collective hallucinations, the gap that the concealment of some part of a loved one’s life produced in us. The phantom is, therefore, also a metapsychological fact. Consequently, what haunts are not the dead, but the gaps left within us by the secrets of others.Because the phantom is not related to the loss of a loved one, it cannot be considered the effect of unsuccessful mourning, as is the case of melancholics or of all those who carry a tomb within themselves. It is the children’s or descendants’ lot to objectify these buried tombs through diverse species of ghosts. What comes back to haunt are the tombs of others. The phantoms of folklore merely objectify a metaphor active within the unconscious: the burial of an unspeakable fact within the loved one.Here we are in the midst of clinical psychoanalysis and still shrouded in obscurity, an obscurity, however, that the nocturnal being of phantoms can, paradoxically, be called upon to clarify. The most recently published book of essays by Nicolas Abraham is Rythmes de l’oeuvre, de la traduction et de la psychanalyse . “Notes on the Phantom” is the preliminary statement of his theory of transgenerational haunting. Nicholas Rand, assistant professor of French at the University of Wisconsin—Madison, is the English-language editor of Abraham’s works. (shrink)

This monograph proposes a new way of implementing interaction in logic. It also provides an elementary introduction to Constructive Type Theory. The authors equally emphasize basic ideas and finer technical details. In addition, many worked out exercises and examples will help readers to better understand the concepts under discussion. One of the chief ideas animating this study is that the dialogical understanding of definitional equality and its execution provide both a simple and a direct way of implementing the CTT approach (...) within a game-theoretical conception of meaning. In addition, the importance of the play level over the strategy level is stressed, binding together the matter of execution with that of equality and the finitary perspective on games constituting meaning. According to this perspective the emergence of concepts are not only games of giving and asking for reasons, they are also games that include moves establishing how it is that the reasons brought forward accomplish their explicative task. Thus, immanent reasoning games are dialogical games of Why and How. (shrink)

Les travaux sociologiques ne manquent pas pour souligner la précarité de l’emploi des artistes et de leur carrière. Un questionnement émerge de ce constat : pourquoi des individus souhaitent-ils s’engager dans un secteur d’activité marqué du sceau de l’incertitude? Pourquoi et comment certains persistent-ils malgré les épreuves? En relatant les récits d’artistes en devenir, l’ouvrage de J-C. Pita Castro apporte un éclairage complémentaire au travail de L.

This book features 20 essays that explore how Latin medieval philosophers and theologians from Anselm to Buridan conceived of habitus, as well as detailed studies of the use of the concept by Augustine and of the reception of the medieval doctrines of habitus in Suàrez and Descartes. Habitus are defined as stable dispositions to act or think in a certain way. This definition was passed down to the medieval thinkers from Aristotle and, to a lesser extent, Augustine, and played a (...) key role in many of the philosophical and theological developments of the time. Written by leading experts in medieval and modern philosophy, the book offers a historical overview that examines the topic in light of recent advances in medieval cognitive psychology and medieval moral theory. Coverage includes such topics as the metaphysics of the soul, the definition of virtue and vice, and the epistemology of self-knowledge. The book also contains an introduction that is the first attempt at a comprehensive survey of the nature and function of habitus in medieval thought. The material will appeal to a wide audience of historians of philosophy and contemporary philosophers. It is relevant as much to the historian of ancient philosophy who wants to track the historical reception of Aristotelian ideas as it is to historians of modern philosophy who would like to study the progressive disappearance of the term “habitus” in the early modern period and the concepts that were substituted for it. In addition, the volume will also be of interest to contemporary philosophers open to historical perspectives in order to renew current trends in cognitive psychology, virtue epistemology, and virtue ethics.
