With armed conflict in the Persian Gulf now upon us, Harvard archaeologist Steven LeBlanc takes a long-term view of the nature and roots of war, presenting a controversial thesis: The notion of the "noble savage" living in peace with one another and in harmony with nature is a fantasy. In Constant Battles: The Myth of the Peaceful, Noble Savage , LeBlanc contends that warfare and violent conflict have existed throughout human history, and that humans have never lived in (...) ecological balance with nature. The start of the second major U.S. military action in the Persian Gulf, combined with regular headlines about spiraling environmental destruction, would tempt anyone to conclude that humankind is fast approaching a catastrophic end. But as LeBlanc brilliantly argues, the archaeological record shows that the warfare and ecological destruction we find today fit into patterns of human behavior that have gone on for millions of years. Constant Battles surveys human history in terms of social organization-from hunter gatherers, to tribal agriculturalists, to more complex societies. LeBlanc takes the reader on his own digs around the world -- from New Guinea to the Southwestern U.S. to Turkey -- to show how he has come to discover warfare everywhere at every time. His own fieldwork combined with his archaeological, ethnographic, and historical research, presents a riveting account of how, throughout human history, people always have outgrown the carrying capacity of their environment, which has led to war. Ultimately, though, LeBlanc's point of view is reassuring and optimistic. As he explains the roots of warfare in human history, he also demonstrates that warfare today has far less impact than it did in the past. He also argues that, as awareness of these patterns and the advantages of modern technology increase, so does our ability to avoid war in the future. (shrink)

Van Rensselaer Potter (1911-2001), le biologiste à l’origine du terme « bioéthique » dans les écrits nord-américains, considère que « real bioethics falls in the context of the ideals of […] Aldo Leopold », un forestier, philosophe et poète ayant marqué le XXe siècle. Associer Leopold à Potter a pour effet de placer la bioéthique dans la famille des éthiques de l’environnement, ce qui la différencie du sens conventionnel retenu en médecine et en recherche depuis le Rapport Belmont (1979), une (...) déclaration ayant propulsé l’institutionnalisation de la bioéthique en Amérique du Nord. Cependant, diviser la bioéthique entre le médical et l’environnemental est réducteur. Potter propose au contraire une bioéthique globale s’intéressant aux enjeux situés à leur interface, dont ceux concernant la terre, la vie sauvage, la surpopulation, la consommation, etc. Cet article vise à amorcer un nouveau chantier d’analyse de la pensée de Potter en s’appuyant sur l’héritage de Leopold en biologie. Une synthèse de cette vision potterienne est proposée de manière à considérer son œuvre comme un tout cohérent s’intégrant aux grands débats qui transcendent les XXe et XXIe siècles. Sa vision apparaît comme une sagesse collective et prospective sous la forme d’une science de la survie et d’un code de bioéthique. Dépassant l’éthique de l’environnement, son association avec Leopold offre un modèle de la complexité s’imposant comme cas indissociable du contexte qui l’englobe, en améliorant nos façons d’intervenir en pratique dans un monde en constante transformation, à titre de gouvernance adaptative et de sagesse de la responsabilité.

Surveillance programs supporting the management of One Health issues such as antibiotic resistance are complex systems in themselves. Designing ethical surveillance systems is thus a complex task (retroactive and iterative), yet one that is also complicated to implement and evaluate (e.g., sharing, collaboration, and governance). The governance of health surveillance requires attention to ethical concerns about data and knowledge (e.g., performance, trust, accountability, and transparency) and empowerment ethics, also referred to as a form of responsible self-governance. Ethics in reflexive governance (...) operates as a systematic critical-thinking procedure that aims to define its value: What are the “right” criteria to justify how to govern “good” actions for a “better” future? The objective is to lay the foundations for a methodological framework in empirical bioethics, the rudiments of which have been applied to a case study to building reflexive governance in One Health. This ongoing critical thinking process involves “mapping, framing, and shaping” the dynamics of interests and perspectives that could jeopardize a “better” future. This paper proposes to hybridize methods to combine insights from collective deliberation and expert evaluation through a reflexive governance functioning as a community-based action-ethics methodology. The intention is to empower individuals and associations in a dialogue with society, which operation is carried out using a case study approach on data sharing systems. We based our reasoning on a feasibility study conducted in Québec, Canada (2018–2021), envisioning an antibiotic use surveillance program in animal health for 2023. Using the adaptive cycle and governance techniques and perspectives, we synthesize an alternative governance model rooted in the value of empowerment. The framework, depicted as a new “research and design (R&D)” practice, is linking operation and innovation by bridging the gap between Reflexive, Evaluative, and Deliberative reasonings and by intellectualizing the management of democratizing critical thinking locally (collective ethics) by recognizing its context (social ethics). Drawing on the literature in One Health and sustainable development studies, this article describes how a communitarian and pragmatic approach can broaden the vision of feasibility studies to ease collaboration through public-private-academic partnerships. The result is a process that “reassembles” the One Health paradigm under the perspective of global bioethics to create bridges between the person and the ecosystem through pragmatic ethics. (shrink)

For Van Rensselaer Potter (1911–2001), Global Bio-Ethics is about building on the legacy of Aldo Leopold (1887–1948), one of the most notable forest managers of the twentieth century who brought to light the importance of pragmatism in the sciences and showed us a new way to proceed with environmental ethics. Following Richard Huxtable and Jonathan Ives's methodological 'Framework for Empirical Bioethics Research Projects' called 'Mapping, framing, shaping,' published in BMC Medicine Ethics (2019)), we propose operationalizing a framework for Global Bio-Ethics (...) by hybridizing approaches in empirical bioethics and ecosystem management. We explain this framework using the metaphor of forest management. This mixed approach is articulated through three phases: (1) mapping the “landscape” to build a working theory, (2) framing the “scene” to prepare the fieldwork, and (3) shaping bioethics “tools” to stimulate cooperation. Applying this methodology, an adaptive management cycle is outlined to help ensure that political processes are sustainable and socially acceptable, still based on strategic and ethical thinking, but also capable of reshaping failing policies.

On the basis of Anton Marty’s 1867 Preisschrift, this article offers a reconstruction of the semiotic and linguistic investigations the Swiss philosopher develops just before becoming a student of Brentano. The paper then compares this account with the view on signs that will be given in Marty’s later work, as well as within the Austro-German tradition.

Potterian bioethics plays a proactive role, when carried out in collaboration with multidisciplinary teams with a mandate to operationalize public policy, as highlighted in the Canadian Journal of Bioethics in 2022 where several articles on Van Rensselaer Potter’s thinking appeared on the 50th anniversary of the first publication of the term bioethics in the North American literature. This global perspective, which is still insufficiently detailed, critically reflects on the place, the role and the imperative of bioethics as an adaptive management (...) of the environment; and it aims to accompany empirical projects in the operation of their scientific, political and public visions, which are sometimes synergistic, and other times conflicting. In order to specify the operationalization of this global perspective of bioethics, it is pertinent to mobilize theoretical notions from sociology and philosophy of science, in particular the Latourian concept of Hybrid Forum and the Paradigm associated to Thomas Kuhn. To illustrate this, the argument presented here mobilizes the empirical case of a project to design a monitoring of antibiotic use in Quebec, Canada (2018-2022), and expands on the importance of being aware of context (technological, sociological and anthropological) in order to deepen and pose constructive criticism. This article presents an alternative perspective to the act of governing by proposing a proactive process of governance. (shrink)

En 1964, Van Rensselaer Potter soulignait l’importance de mailler le Droit, la Science et les communautés afin de bien traduire les savoirs humains en actions responsables – pour la qualité de vie et envers l’environnement. Cette réponse rappelle les enseignements de ce scientifique et précurseur de la bioéthique, dont la pensée demeure encore aujourd’hui marginale, au profit d’une vision juridique, philosophique, voire théologique axée sur la valeur de la santé humaine.

Understanding arithmetic word problems involves a complex interaction of text comprehension and mathematical processes. This article presents a computer simulation designed to capture the working memory demands required in “bottomup” comprehension of arithmetic word problems. The simulation's sentence‐level parser and text integration component reflect the importance of processing the problem from its original natural language presentation. Children's probability of solution was analyzed in exploratory regression analyses as a function of the simulation's sentence‐level and text integration processes. Working memory variables measuring (...) the combined effects of concepts to remember and text integration inferences account for a significant proportion of variance in children's solution probabilities across the first four grade levels (K‐3). Consistent with previous results from others, which highlighted the significance of small changes in problem wording, the simulation offers a process‐oriented perspective as to why natural language presentation constrains the comprehension of mathematical relationships.

Recent corporate scandals have put company boards in the spotlight. Legislation, codes of conduct, and guidelines have been developed to improve corporate governance. But while many prescriptions for improving corporate governance focus on the structure of boards, Dr. Richard Leblanc's research suggests that there is no direct causal relationship between board structure and corporate performance. Indeed, many recent failed corporations had exemplary board structure. Richard Leblanc discusses how to assess board effectiveness and improve it.

Kolmogorov's account in his [1933] of an absolute probability space presupposes given a Boolean algebra, and so does Rényi's account in his [1955] and [1964] of a relative probability space. Anxious to prove probability theory ‘autonomous’. Popper supplied in his [1955] and [1957] accounts of probability spaces of which Boolean algebras are not and [1957] accounts of probability spaces of which fields are not prerequisites but byproducts instead.1 I review the accounts in question, showing how Popper's issue from and how (...) they differ from Kolmogorov's and Rényi's, and I examine on closing Popper's notion of ‘autonomous independence’. So as not to interrupt the exposition, I allow myself in the main text but a few proofs, relegating others to the Appendix and indicating as I go along where in the literature the rest can be found.

Teddy Seidenfeld recently claimed that Kolmogorov's probability theory transgresses the Substitutivity Law. Underscoring the seriousness of Seidenfeld's charge, the author shows that (Popper's version of) the law, to wit: If (∀ D)(Pr(B,D)=Pr(C,D)), then Pr(A,B)=Pr(A,C), follows from just C1. 0≤ Pr(A,B)≤ 1 C2. Pr(A,A)=1 C3. Pr(A & B,C)=Pr(A,B & C)× Pr(B,C) C4. Pr(A & B,C)=Pr(B & A,C) C5. Pr(A,B & C)=Pr(A,C & B), five constraints on Pr of the most elementary and most basic sort.

Intellectual historians have rarely attended to the genre of fighting manuals, but these provide a new window on long-debated questions such as the relationship between Scholasticism and Humanism. This article offers a close comparison of the first known fencing manual, the 14-th century Liber de Arte Dimicatoria (Leeds, Royal Armouries FECHT 1, previously and better known as MS I.33), and the corpus of fighting manuals which underwent a remarkable expansion during the 15th and 16th centuries. While the former clearly shows (...) its origins in a scholastic background, the latter is mainly viewed as reflecting its humanist context. To this historiographical division corresponds a linguistic one: MS I.33 is a Latin text, while the rest of the corpus is mainly written in German and Italian. However, exceptions arise, amongst which, Heinrich von Gunterrodt’s Sciomachia et Hoplomachia: sive de Veris Principiis Artis Dimicatoriae (1579), the first text which explicitly refers to I.33. This article will compare these two texts, in order to interrogate their common relation to Scholasticism, namely the traditional frame of the knowledge within the medieval and early modern universities. The intent is to show that (at least some) Renaissance fight books include references to Scholasticism and to provide a better qualification of the nature of such references. The general hypothesis is that a large part of the texts―and products of culture―of the Renaissance that have been read, until recently, exclusively in relation to a humanist intellectual background can valuably be interpreted in the context of a Scholasticism that is still vivid during the period in question.

L’idée d’une gouvernance collaborative gagne en popularité. Cependant, comment être véritablement collaboratif ? Les systèmes de prises de décision diversifiés en intervenants doivent composer avec des parties prenantes aux positions, aux rôles, aux intérêts, aux missions, aux observations et aux valeurs différents. Par sa formule facile d’utilisation pour les éthicien·ne·s professionnel·le·s, l’outil de bioéthique co P·R·I·M·O·V (Position, Rôle, Intérêt, Mission, Observation, Valeurs) vise à améliorer la pratique des initiatives technosociales pour un développement durable, collaboratif et démocratique. L’outil reprend la logique (...) d’analyse des conflits d’intérêts (CI) issue des cadres en éthique organisationnelle. Les CI, comme unité analytique en éthique, permettent d’anticiper et de gérer les problèmes pouvant compromettre à court et à long termes les activités d’un programme et sa gouvernance. L’outil a été construit à la suite d’une étude de cas sur la mise en œuvre d’un monitorage de l’utilisation des antibiotiques en santé animale au Québec, Canada. L’usage de cet outil de bioéthique est stratégique et aide à la négociation des positions, puis à la coconstruction d’un référentiel commun entre les parties prenantes en vue de préparer le terrain à une gouvernance collaborative favorisant la coopération.

La Divine Comédie est le récit poétique d'une vision, d'une expérience surnaturelle qui se fait toujours plus intense, et que le langage peine toujours davantage à traduire. La mission de Dante consiste à rapporter cette vision. La question que nous pose la Divine Comédie réside dans la différence entre l'intraduisible et l'indicible: y a-t-il un intraduisible dicible? Ou en d'autres termes : quelle est, au-delà du topos de l'indicible poétique, et au-delà de la figure rhétorique de la prétérition, la signification (...) conceptuelle de l'expression du "dire" dans la Divine Comédie?

Nous présentons ici la traduction d’une conférence donnée par Ernst Cassirer au Cercle linguistique de New York en 1945, intitulée « Le structuralisme dans la linguistique moderne ». Dans ce texte, Cassirer propose une généalogie de l’approche structurale dans la linguistique moderne, en faisant remonter la problématique aux débats épistémologiques des xviiie et xixe siècles sur la constitution des sciences du vivant. La conférence de Cassirer revêt ainsi à nos yeux un double intérêt : d’une part, elle rend compte de (...) l’unité de l’œuvre cassirerienne, puisque l’auteur y mobilise des concepts dont il a posé les premiers jalons dès 1910 dans Substance et fonction ; d’autre part, elle permet de rendre compte de la spécificité méthodologique des sciences de la culture, à partir d’une généalogie conceptuelle de la méthode en train de naître dans les cercles linguistiques de l’époque. Nous tâcherons de présenter les différentes étapes de l’argumentation de Cassirer, allant d’une redéfinition de la nécessité dans le domaine linguistique, en passant par l’analogie entre science du vivant et science du langage, pour finir par interroger la place accordée à la notion de structure dans la philosophie de Cassirer.
