Este artigo recorda os principais aspectos e motivações da Expedição Langsdorff, missão de reconhecimento do interior do Brasil iniciada em 1821, composta pelo cônsul russo barão Langsdorff, o pintor alemão Moritz Rugendas, Aimé-Adrien Taunay, Nicolas-Antoine Taunay, o polígrafo Hercules Florence e o especialista em mapas Néster G. Rubtsov. Busca diferenças entre esta expedição e iniciativas outras, a título de exemplo, as dos bandeirantes e jesuítas, bem como a expedição indigenista de Rondon, e propõe o aprofundamento das investiga­ções. Apresenta atributos (...) resgatados pela poesia brasileira contemporânea e elementos cons­titutivos da identidade cultural brasileira presentes na Expedição Langsdorff, os quais os auto­res sugerem ser relevantes para pesquisadores do tema e para a inserção do Brasil no contexto internacional político, diplomático e econômico nos tempos hodiernos.

RésuméL'objet du présent article est de dégager la signification philosophique des différents théoriémes de métamathématique relatifs à la puissance des formalisations. Ces théorèmes représentent la partie de l'épistémologie qui peut être exposée dans la forme technique de la science elle‐même et rassemblant les éléments d'une réflexion autocritique de la pensée mathématique sur elle‐même. Au‐delà, ils invitent à comprendre l'acte de la pensée mathématique comme déploiement d'un projet pensant supposant à la fois une initiative volontaire de la pensée, un champ intuitif (...) absolument indéfini et une exigence logique régulatrice, et amènent la philosophie de la science à se demander si, telles qu'ellcs sont, les mathématiques sont l'unique forme de synthèse rigoureuse possible entre ces trois moments de la pensée.

In this brief essay Vanhoutte treats the complex structure of the Gorgias with remarkable care. Freedom and constraint in human responses and in the form of discussion are the key strands he separates.--R. P.

Not a conventional history, this work is organized in terms of the author's understanding of the developing ideas of philosophy from the Italian Renaissance to the twentieth century. The first part of the work is developed along the tensions between the empiricist and Platonic traditions; thus Berkeley is seen in relation to Locke and Hume but also to the Cambridge Platonists. A novel facet of the middle part of the work is the large section separating Leibniz and Kant, devoted to (...) the developing critical spirit in Les Philosophes from Bayle to the Encyclopedia and to Rousseau and Condillac, as well as Thomas Reid and the Scottish school of common sense. After the Hegelians the work closes with a brief discussion of the philosophies of action and process and existentialism. Boas gives to many of his subjects interesting and valuable reinterpretations within the perspective of a concern for the development of ideas.--R. P. (shrink)

In this article, we present results from a literature review of intrinsic, instrumental, and relational values of nature conducted for the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services, as part of the Methodological Assessment of the Diverse Values and Valuations of Nature. We identify the most frequently recurring meanings in the heterogeneous use of different value types and their association with worldviews and other key concepts. From frequent uses, we determine a core meaning for each value type, which is (...) sufficiently inclusive to serve as an umbrella over different understandings in the literature and specific enough to help highlight its difference from the other types of values. Finally, we discuss convergences, overlapping areas, and fuzzy boundaries between different value types to facilitate dialogue, reduce misunderstandings, and improve the methods for valuation of nature's contributions to people, including ecosystem services, to inform policy and direct future research. © 2023 The Author(s).

Les décisions politiques sur les risques environnementaux complexes font fréquemment intervenir des éléments scientifiques contestés. Il n’y a généralement pas de « faits » qui conduisent à une politique correcte unique. Les éléments de preuve qui sont intégrés dans les avis scientifiques destinés à une décision politique nécessitent une évaluation de leur qualité. En 2003, l’Agence néerlandaise d’évaluation environnementale a adopté une méthode standardisée, désignée sous le nom de « guide », dans le cadre de laquelle les principaux aspects de (...) la production et de l’utilisation des connaissances sont présentés grâce à une liste de contrôle visant à l’évaluation et à la communication des incertitudes. Dans cet article, nous présentons des résultats de l’application de ce guide à la controverse sur les risques des particules en suspension. La délibération active sur l’incertitude dans un contexte d’expertise entraîne un processus d’apprentissage commun entre les experts et les décideurs politiques, ce qui conduit à une meilleure prise de conscience du phénomène d’incertitude et de ses implications politiques.Policy decisions on complex environmental risks often involve disputed science. Typically, there are no “ facts” to support a single unequivocally correct policy. The evidence provided in scientific studies for policy-making decisions requires high-quality assessment. In 2003, the Netherlands Environmental Assessment Agency adopted a standardized method, referred to as “guidelines”, whereby key quality aspects of knowledge production and use are presented in the form of a checklist for uncertainty assessments and communication. In this article, we present the outcomes of applying the guidelines in controversies on the risks of ambient particulate matter. In the policy–advisory context, active deliberation on uncertainty produces a common learning process for advisors and policy makers, which leads to a deeper understanding and increased awareness of the phenomenon of uncertainty and its policy implications.

A well-written translation of Cournot's Essai sur les fondements de nos connaissances et sur les caractères de la critique philosophique. The author, little known in this country except for his work in mathematics and economics, first published this work in 1851. The Essay is part rationalism, part empiricism. The first half of the Essay argues for Cournot's theory of knowledge; the second relates his theory to problems of mathematics, logic, law, history, psychology, ethics, esthetics, and to his philosophical predecessors. It (...) is a work which will reward careful study and which will be of special interest to students of Peirce and Bergson. The translator has provided a lengthy introduction which will be of value to those unfamiliar with Cournot and Cournot literature, and an excellent index. --R. P. (shrink)

Les professeurs Macey et Miller analysent la relation entre l’assurance des dépôts et l’ inadé quation dans la structure des échéances des actifs et passifs des banques commerciales. Après avoir critiqué l’hypothèse traditionnelle concernant la réglementation, d’après laquelle les banques sont incitées à financer les actifs à long terme par des passifs à court terme parce que l’assurance des dépôts garantie par l’Etat stimule le crédit des banques et subventionne les passifs à court terme, ils utilisent l’analyse économique des décisions (...) publiques pour soutenir qu’une version modifiée de l’hypothèse de la réglementation est la meilleure explication de la déstructuration des échéances des actifs et passifs bancaires.Finalement, ils considèrent que soutenir l’hypothèse de la réglementation n’entraîne pas l’ acceptation du modèle d’assurance des dépôts garantie par l’Etat tel qu’il existe aux Etats-Unis aujourd’hui.Professors Macey and Miller explore the relationship between deposit insurance and the mismatch in the term structure of commercial banks’ assets and liabilities. After criticizing the traditional regulatory hypothesis, which posits that banks have incentives to fund long-term assets with short-term liabilities because government-sponsored deposit insurance enhances bank credit and subsidizes short-term liabilities, they use public choice theory to argue that a modified version of the regulatory hypothesis is the best explanation for the mismatch in the term structure of banks’ assets and liabilities. Finally, they argue that embracing the regulatory hypothesis does not imply acceptance of the government-sponsored deposit insurance scheme as it exists in the U.S. today. (shrink)
