This book consists of a series of papers "read and discussed at the first Symposium of Exact Philosophy" at Montreal in 1971. "Exact philosophy," the editor says, means "mathematical philosophy, i.e., philosophy done with the explicit help of mathematical logic and mathematics." Judging from the contents, a more accurate statement would be that "exact philosophy" means formal semantics and modal logic. Two thirds of the papers are on these topics. The others include an essay on "Concepts of Randomness" by Peter (...) Kirschenmann; a characteristically difficult paper on "Plato’s Phaedo Theory of Relations" by Hector Castañeda; a somewhat inexact discursus on "Foundations as a Branch of Mathematics" by William Hatcher with a reply by Charles Castonguay; and a paper by Raimo Tuomela on "Deductive Explanation of Scientific Laws", or, more exactly, on Ohmer’s discussion of that topic. The subject’s are highly specialized and their treatment is complex. In addition to those mentioned, other essays are "Matters of Relevance" by Hugues Leblanc, with an answer by Brian Chellas; "Translation and Reduction" by Lars Svenonius; "A Program for the Semantics of Science" by Mario Bunge; "S-P Interrogatives" by Nuel Belnap; "The Logic of Conditional Obligation" by Bas C. Van Frassen with commentary by Harry Beaty; and "The Intuitive Background of Normative Legal Discourse and Its Formalization" by Carlos E. Alchourron.—M.H. (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)

This evenhanded treatment addresses the decades-old dispute among probability theorists, asserting that both statistical and inductive probabilities may be treated as sentence-theoretic measurements, and that the latter qualify as estimates of the former. Beginning with a survey of the essentials of sentence theory and of set theory, the author examines statistical probabilities, showing that statistical probabilities may be passed on to sentences, and thereby qualify as truth-values. An exploration of inductive probabilities follows, demonstrating their reinterpretation as estimates of truth-values. Each (...) chapter is preceded by a summary of its contents. Illustrations and footnotes elucidate definitions, theorems, and technicalities. 1962 ed. (shrink)

I investigate the mystic's claim that God, or the experience of God, is "beyond" language. Taking St John of the Cross as a primary text, I isolate the reasons that he gives for the ineffability that he claims, determine the theory or theories of language that underlie these reasons, and ask whether these are adequate reasons for ineffability. ;St John of the Cross offers various suggestions about why he should be unable to find the right words to describe his experience. (...) I elucidate these suggestions in terms of his own tradition, and then consider them in light of other, more systematic, philosophies of language. ;On the surface, SJC's position seems incoherent, since his descriptions of mystical rapture refute what seem to be his metalinguistic views. I argue that SJC's ineffability claims are strictly speaking false. ;To say that the ineffability claims are false, however, is not to say they are without value. I argue that in context, expressions like 'It is more than I can say' actually function not as claims, but as disclaimers. These disclaimers have a characteristic rhetorical force: they serve as intensifiers, which further delineate the content of description; they have a certain imperative force; and they warn the aspiring mystic not to be turned from contemplation towards mundane values.

This edited collection of eight original essays pursues the aim of bringing the spotlight back on Anton Marty. It does so by having leading figures in the contemporary debate confront themselves with Marty’s most significative contributions, which span from philosophy of mind, philosophy of language and ontology to meta-metaphysics and meta-philosophy. -/- The book is divided in three parts. The first part is dedicated to themes in philosophy of language, which were at the centre of Marty’s philosophical thinking throughout his (...) life. The second part focuses on the problem of the objectivity and phenomenology of time and space, upon which Marty was working in the final years of his life. The final part turns to Marty’s meta-metaphysical and meta-philosophical considerations. The intended audience of this book are primarily scholars and students interested in the relevant contemporary debates, as well as scholars working on the Austrian tradition. (shrink)
